Can Biotechnology Solve World Hunger? – Good Herald

June 5th, 2017 8:41 pm

Hunger and scarcity of food is one of the major problems in most of the developing countries. Moreover with the increased food price in the developing countries, more than 100 million people are suffering from scarcity of food and hunger. So these are the major recurring challenges that have tackled for centuries. To overcome from these issues, new technologies have enabled the significant changes for improving the quality of life.

Todays modern molecular biotechnology has enabled new solution to overcome from these challenges. The evolution of molecular biotechnology industry has substantially increased its efforts to find alternative to synthetic food and new innovations on the conventional plant breeding technologies. Also the advanced biotechnology offers an exciting and environmentally new way to reach the customer demand for sustainable agriculture growth.

Here we shall have a brief discussion on modern biotechnology and how it solves world hunger.

1. Prevent Hunger And Malnutrition

The term malnutrition is the medical terminology for the people who are all suffering from the hunger. As per the recent survey from the Agricultural Organization, more than 900 million people suffering from malnutrition in worldwide. Children are the major victims for the malnutrition. To overcome from this researchers have created Golden Rice which contains three new genes. This rice is available for mass distribution at low cost. This is just one sample, there are hundreds of new biotech products which prevent hunger and malnutrition.

2. Longer Lasting Produce

Most of the food products will spoil soon, especially in areas with limited transportation and refrigeration capability. But the biotech products could reduce looses to spoilage. In most of the developing countries, farmers can get benefits from crops with delayed ripening fruits or vegetables. This also allows greater flexibility in distribution of products in remote places.

3. Nutritionally Rich Food

Molecular biotechnology researchers have developed nutritionally rich food with beta-carotene and precursor to Vitamin A food for the low poverty level people at low cost. The United Nations Food and Agricultural Department have stated: The potential to grow rice with an enhanced micronutrient can contribute to reducing malnutrition.

4. Tackling New Diseases

Before some of the genetic engineers was only dealing with pharmaceutical industry. But now biotechnology field has spread its wings wider in the health care industry and contribute to treat medical diseases by avoiding the use of insulin and other chemicals. With biotechnology, it includes interferon therapy to dissolve ones immune system and introduced hepatitis B vaccine for low cost.

Arthritis symptoms – gentle jogging could benefit knee and hip joints … – Express.co.uk

June 5th, 2017 8:41 pm

GETTY

A gentle jog could benefit the knees and hips and reduce the risk of the osteoarthritis, which affects millions of people in the UK.

There is currently no cure for the condition but sufferers can treat the condition with drugs - commonly non-steroidal anti-inflammatory drugs and by changing certain lifestyle factors.

Previously, experts have suggested jogging could damage the major joints and recommend other exercises such as pilates.

A new study looked at more than 110,000 people across the world. It found 3.5 per cent of people who run for fun and to stay fit developed arthritis in the knees or hips.

GETTY

This, experts said was compared to 10.2 per cent of those who didn't do any running - and was true for both men and women.

However the researchers said people should be wary of doing too much - as training and running competitively increased the risk to 13.3 per cent.

Dr Eduard Alentorn-Geli, of the Mayo Clinic in Rochester, Minnesota, and orthopaedic surgeon said: "The principal finding in this study is that, in general, running is not associated with osteoarthritis.

"The novel finding in our investigation is the increased association between running and arthritis in competitive - but not in recreational - runners.

When a joint develops osteoarthritis, some of the cartilage covering the ends of the bones gradually roughens and becomes thin, and the bone underneath thickens.

Running is not associated with osteoarthritis

According to Arthritis Research UK, over eight million people in the UK suffer from osteoarthritis - a condition perceived as only a disorder that affects the elderly.

Dr Alentorn-Gel and researchers from Spain, Sweden, and Canada pooled data from 17 studies involving a total of 114,829 people to evaluate the association of osteoarthritis with running.

The researchers compared the prevalence of the disease between runners and sedentary individuals who did not run.

Runners were considered 'competitive' if they were identified themselves as professional or elite athletes or participated in international competitions.

The researchers calculated the rate and odds ratio for osteoarthritis between runners at both competitive and recreational levels and people who did no exercise individuals.

They also looked at the location of arthritis in the hip or knee, gender and the years of exposure to running - less or more than 15 years.

GETTY

Dr Alentorn-Geli and his colleagues were not able to determine the amount of running that is safe for these joints.

The study was published in the Journal of Orthopaedic & Sports Physical Therapy.

Olivia Belle from Arthritis Research UK has previously told Express.co.uk said: If you have joint pain or mild osteoarthritis you might not always feel much like exercising.

But keeping active is one of the best ways to manage the symptoms.

Regular, safe, simple and effective exercise has been proven to greatly reduce pain and stiffness in joints.

Its also important for your joints that you maintain a healthy weight for you, and exercising regularly will help you with that.

Arthritis cure: Ditching THIS from your diet could ease symptoms – Express.co.uk

June 5th, 2017 8:41 pm

Reducing carbohydrates, such as bread and pasta, could better kickstart your immune system to fight disease.

One of its components - glucose - interferes with some of the bodys immune cells.

The simple sugar is generated when we digest carbs, and as well as being vital for energy its also important in cell division and growth.

However, in some cases it can stop the immune system working properly, and therefore help drive disease.

GETTY

Research by Trinity College Dublin discovered that when certain cells are starved of glucose, they stimulated the immune system.

Research by Trinity College Dublin discovered that when certain cells are starved of glucose, they stimulated the immune system.

These dendritic cells are the part of the immune system that monitors our body for signs of danger.

When they arent given of glucose, they push the immune systems T lymphocytes into action.

Indeed, they are what directly fight cancer and inflammatory diseases, such as arthritis and heart problems.

There are other immune cells, however, which become dysfunctional if they're starved of glucose.

This is because when responding to infection they have a high demand for it.

The research outlines how various cells may interact with glucose differently.

GETTY

The study authors believe the new findings could open up new approaches to treating cancers and immune-related conditions.

David Finlay, lead researcher, said: It is becoming clear that glucose is an important signaller in our immune system, in that cells that have access to glucose behave very differently to those that do not.

We have discovered that dendritic cells are actually better at stimulating immune responses when starved of glucose, which is not the case for any of the other immune cells that have been analysed.

The discovery that T cells and dendritic cells compete with each other for glucose offers a new and exciting insight into how glucose can regulate dendritic cell function.

Walkers stepping up to stamp out arthritis – Tbnewswatch.com

June 5th, 2017 8:41 pm

THUNDER BAY - Even though damp, cold weather can make even standing up difficult for people living with severe arthritis, dozens of people braved a grey morning to walk in support of the Arthritis Society.

On Sunday, more than 70 people participated in the 8th Annual Walk to Fight Arthritis at Prince Arthurs Landing.

Mariann Sawicki, committee member with the Arthritis Society of Thunder Bay, said she is happy with the turn out.

The weather probably deterred some people, she said. There are a lot of people out here. It just goes to show the importance. Everybody wants to do what they can for different diseases. They are very eager to help out and show their support.

This year, the fundraising target was $19,000 and prior to the walk starting the Arthritis Society had already raised $12,000. The money raised will be used to fund research for arthritis treatments and finding a cure.

Arthritis refers to a number of different disorders that target the joints in the body. It can cause stiffness, swelling, and reduced motion of joints. Types of arthritis include osteoarthritis, rheumatoid arthritis, lupus, gout, and Lyme Disease.

Sawicki said sometimes there are misconceptions that arthritis is a disease that only affects people as they age, but she said it can affect anyone.

I think there may be some misconception, she said. A lot of people may think it is for older people, but thats not the case. Im a registered nurse and Ive seen all kind of different types of arthritis. People need to realize that.

And despite the weather on Sunday, people were out not only in support of stamping out arthritis, but also practicing one of the best treatments for the disease.

Movement with arthritis is one of the best things for you and your joints, Sawicki said. Being active really helps. This weather is kind of damp, so it does trigger some symptoms for people, but people are still out here and ready to go.

Gene therapy could wipe immune memory and "turn off" severe allergies – New Atlas

June 5th, 2017 6:44 am

The team hopes to develop a single, injected, gene therapy treatment that could eliminate many severe allergic responses (Credit: University of Queensland)

Scientists may be one step closer to discovering a way to genetically "turn off" allergic responses with a single injection. A team of researchers at the University of Queensland has developed a new process that has successfully silenced a severe allergic response in mice, using blood stem cells engineered with a gene that can target specific immune cells.

The big challenge previous allergy researchers faced was that immune cells, known as T-cells, tended to develop a form of "memory" so that once someone developed an immune response to an allergen, it would easily recur upon future contact. The key was finding a way to erase that "memory" response to the protein in the allergen causing the immune reaction.

NEW ATLAS NEEDS YOUR SUPPORT

It's just US$19 a year.

"We take blood stem cells, insert a gene which regulates the allergen protein and we put that into the recipient," says Professor Ray Steptoe, explaining the new process developed by his team at The University of Queensland. "Those engineered cells produce new blood cells that express the protein and target specific immune cells, 'turning off' the allergic response."

The team's initial clinical investigations looked at an experimental asthma allergen, with the new process found to successfully terminate established allergic responses in sensitized laboratory mice. While the initial research has focused on a very specific asthma allergen, Professor Steptoe believes the process could be applied to many other severe allergic responses, such as peanuts, bee venom and shell fish.

The long-term goal of the research would be to develop a therapy that could cure specific allergies with a single injection, much like a vaccine.

"We haven't quite got it to the point where it's as simple as getting a flu jab," says Professor Steptoe, "so we are working on making it simpler and safer so it could be used across a wide cross-section of affected individuals."

The team is realistic about the time it will take before this discovery results in practical benefits for allergy sufferers, with at least five years more laboratory work needed before even human trials can be conducted. But this new discovery could mean that, within 10 or 15 years, asthma and other lethal allergic responses might be eliminated with a single, one-time treatment.

The findings were recent published in the journal JCI Insight.

What Are Stem Cells – Checkbiotech.org (press release)

June 5th, 2017 6:43 am

Tissue-specific stem cells

Tissue-specific stem cells, which are sometimes referred to as adult or somatic stem cells, are already somewhat specialized and can produce some or all of the mature cell types found within the particular tissue or organ in which they reside. Because of their ability to generate multiple, organ-specific, cell types, they are described as multipotent. For example, stem cells found

Stem cells are the foundation cells for every organ and tissue in our bodies. The highly specialized cells that make up these tissues originally came from an initial pool of stem cells formed shortly after fertilization. Throughout our lives, we continue to rely on stem cells to replace injured tissues and cells that are lost every day, such as those in our skin, hair, blood and the lining of our gut. Stem cells have two key properties: 1) the ability to self-renew, dividing in a way that makes copies of themselves, and 2) the ability to differentiate, giving rise to the mature types of cells that make up our organs and tissues.

Tissue-specific stem cells Tissue-specific stem cells, which are sometimes referred to as adult or somatic stem cells, are already somewhat specialized and can produce some or all of the mature cell types found within the particular tissue or organ in which they reside. Because of their ability to generate multiple, organ-specific, cell types, they are described as multipotent. For example, stem cells found within the adult brain are capable of making neurons and two types of glial cells, astrocytes and oligodendrocytes. Tissue-specific stem cells have been found in several organs that need to continuously replenish themselves, such as the blood, skin and gut and have even been found in other, less regenerative, organs such as the brain. These types of stem cells represent a very small population and are often buried deep within a given tissue, making them difficult to identify, isolate and grow in a laboratory setting. Neuron Dr. Gerry Shaw, EnCor Biotechnology Inc. Astrocyte Abcam Inc. Oligodendrocyte Dhaunchak and Nave (2007). Proc Natl Acad Sci USA 104:17813-8 http://www.isscr.org Embryonic stem cells Embryonic stem cells have been derived from a variety of species, including humans, and are described as pluripotent, meaning that they can generate all the different types of cells in the body. Embryonic stem cells can be obtained from the blastocyst, a very early stage of development that consists of a mostly hollow ball of approximately 150-200 cells and is barely visible to the naked eye. At this stage, there are no organs, not even blood, just an inner cell mass from which embryonic stem cells can be obtained. Human embryonic stem cells are derived primarily from blastocysts that were created by in vitro fertilization (IVF) for assisted reproduction but were no longer needed. The fertilized egg and the cells that immediately arise in the first few divisions are totipotent. This means that, under the right conditions, they can generate a viable embryo (including support tissues such as the placenta). Within a matter of days, however, these cells transition to become pluripotent. None of the currently studied embryonic stem cell lines are alone capable of generating a viable embryo (i.e., they are pluripotent, not totipotent). Why are embryonic stem cells so valuable? Unlike tissue-specific (adult) stem cells, embryonic stem cells have the potential to generate every cell type found in the body. Just as importantly, these cells can, under the right conditions, be grown and expanded indefinitely in this unspecialized or undifferentiated state. These cells help researchers learn about early human developmental processes that are otherwise inaccessible, study diseases and establish strategies that could ultimately lead to therapies designed to replace or restore damaged tissues. Induced pluripotent stem cells One of the hottest topics in stem cell research today is the study of induced pluripotent stem cells (iPS cells). These are adult cells (e.g., skin cells) that are engineered, or reprogrammed, to become pluripotent, i.e., behave like an embryonic stem cell. While these iPS cells share many of the same characteristics of embryonic stem cells, including the ability to give rise to all the cell types in the body, it is important to understand that they are not identical. The original iPS cells were produced by using viruses to insert extra copies of three to four genes known to be important in embryonic stem cells into the specialized cell. It is not yet completely understood how these three to four reprogramming genes are able to induce pluripotency; this question is the focus of ongoing research. In addition, recent studies have focused on alternative ways of reprogramming cells using methods that are safer for use in clinical settings. Disease- or patient-specific pluripotent stem cells One of the major advantages of iPS cells, and one of the reasons that researchers are very interested in studying them, is that they are a very good way to make pluripotent stem cell lines that are specific to a disease or even to an individual patient. Disease-specific stem cells are powerful tools for studying the cause of a particular disease and then for testing drugs or discovering other approaches to treat or cure that disease. The development of patientspecific stem cells is also very attractive for cell therapy, as these cell lines are from the patient themselves and may minimize some of the serious complications of rejection and immunosuppression that can occur following transplants from unrelated donors. Moving stem cells into the clinic Clinical translation is the process used to turn scientific knowledge into real world medical treatments. Researchers take what they have learned about how a tissue usually works and what goes wrong in a particular disease or injury and use this information to develop new ways to diagnose, stop or fix what goes wrong. Before being marketed or adopted as standard of care, most treatments are tested through clinical trials. Sometimes, in attempting new surgical techniques or where the disease or condition is rare and does not have a large enough group of people to form a clinical trial, certain treatments might be tried on one or two people, a form of testing sometimes referred to as innovative medicine. For more information on how science becomes medicine, please visit http://www.closerlookatstemcells.org. Current therapies Blood stem cells are currently the most frequently used stem cells for therapy. For more than 50 years, doctors have been using bone marrow transplants to transfer blood stem cells to patients, and more advanced techniques for collecting blood stem cells are now being used to treat leukemia, lymphoma and several inherited blood disorders. Umbilical cord blood, like bone marrow, is often collected as a source of blood stem cells and in certain cases is being used as an alternative to bone marrow transplantation. Additionally, some bone, skin and corneal diseases or injuries can be treated by grafting tissues that are derived from or maintained by stem cells. These therapies have also been shown to be safe and effective. Potential therapies Other stem cell treatments, while promising, are still at very early experimental stages. For example, the mesenchymal stem cell, found throughout the body including in the bone marrow, can be directed to become bone, cartilage, fat and possibly even muscle. In certain experimental models, these cells also have some ability to modify immune functions. These abilities have created considerable interest in developing ways of using mesenchymal stem cells to treat a range of musculoskeletal abnormalities, cardiac disease and some immune abnormalities such as graft-versus-host disease following bone marrow transplant. Remaining challenges Despite the successes we have seen so far, there are several major challenges that must be addressed before stem cells can be used as cell therapies to treat a wider range of diseases. First, we need to identify an abundant source of stem cells. Identifying, isolating and growing the right kind of stem cell, particularly in the case of rare adult stem cells, are painstaking and difficult processes. Pluripotent stem cells, such as embryonic stem cells, can be grown indefinitely in the lab and have the advantage of having the potential to become any cell in the body, but these processes are again very complex and must be tightly controlled. iPS cells, while promising, are also limited by these concerns. In both cases, considerable work remains to be done to ensure that these cells can be isolated and used safely and routinely. Second, as with organ transplants, it is very important to have a close match between the donor tissue and the recipient; the more closely the tissue matches the recipient, the lower the risk of rejection. Being able to avoid the lifelong use of immunosuppressants would also be preferable. The discovery of iPS cells has opened the door to developing patient-specific pluripotent stem cell lines that can later be developed into a needed cell type without the problems of rejection and immunosuppression that occur from transplants from unrelated donors. Third, a system for delivering the cells to the right part of the body must be developed. Once in the right location, the new cells must then be encouraged to integrate and function together with the bodys other cells. http://www.isscr.org Glossary Blastocyst A very early embryo that has the shape of a ball and consists of approximately 150-200 cells. It contains the inner cell mass, from which embryonic stem cells are derived, and an outer layer of cells called the trophoblast that forms the placenta. Cell line Cells that can be maintained and grown in a dish outside of the body. Clinical translation The process of using scientific knowledge to design, develop and apply new ways to diagnose, stop or fix what goes wrong in a particular disease or injury. Differentiation The process of development with an increase in the level of organization or complexity of a cell or tissue, accompanied by a more specialized function. Embryo The early developing organism; this term denotes the period of development between the fertilized egg and the fetal stage. Embryonic stem cell Cells derived from very early in development, usually the inner cell mass of a developing blastocyst. These cells are self-renewing (can replicate themselves) and pluripotent (can form all cell types found in the body). Induced pluripotent stem (iPS) cell Induced pluripotent cells (iPS cells) are stem cells that were engineered (induced) from non-pluripotent cells to become pluripotent. In other words, a cell with a specialized function (for example, a skin cell) that has been reprogrammed to an unspecialized state similar to that of an embryonic stem cell. Innovative medicine Treatments that are performed on a small number of people and are designed to test a novel technique or treat a rare disease. These are done outside of a typical clinical trial framework. In vitro fertilization A procedure in which an egg cell and sperm cells are brought together in a dish to fertilize the egg. The fertilized egg will start dividing and, after several divisions, forms the embryo that can be implanted into the womb of a woman and give rise to pregnancy. Mesenchymal stem cells Mesenchymal stem cells were originally discovered in the bone marrow, but have since been found throughout the body and can give rise to a large number of connective tissue types such as bone, cartilage and fat. Multipotent stem cells Stem cells that can give rise to several different types of specialized cells, but in contrast to a pluripotent stem cell, are restricted to a certain organ or tissue types. For example, blood stem cells are multipotent cells that can produce all the different cell types that make up the blood but not the cells of other organs such as the liver or brain. Pluripotent stem cells Stem cells that can become all the cell types that are found in an implanted embryo, fetus or developed organism. Embryonic stem cells are pluripotent stem cells. Self-renewal The process by which a cell divides to generate another cell that has the same potential. Stem cells Cells that have both the capacity to self-renew (make more stem cells by cell division) and to differentiate into mature, specialized cells. Tissue-specific stem cells (also known as adult or somatic stem cells) Stem cells found in different tissues of the body that can give rise to some or all of the mature cell types found within the particular tissue or organ from which they came, i.e., blood stem cells can give rise to all the cells that make up the blood, but not the cells of organs such as the liver or brain. Totipotent stem cells Stem cells that, under the right conditions, are wholly capable of generating a viable embryo (including the placenta) and, for humans, exist until about four days after fertilization, prior to the blastocyst stage from which embryonic stem cells are derived.

Do Carrots Really Help Your Vision? : The Salt : NPR – NPR

June 5th, 2017 6:43 am

Many lifelong carrot eaters feel a little betrayed.

"There is no way [carrots] affect eyesight," says Silvio Fontecchio, a project manager at a print shop in Tallahassee, Fla., whose parents told him when he was young that munching the orange veggie would help his eyes. "As a kid, my go-to snack was carrots and ranch [dressing], and I have really bad nearsighted vision."

For some, disillusion comes even earlier: When Rozalynn Goodwin, a health care executive in Columbia, S.C., told her 6-year-old son to eat his carrots to help his eyesight, he said, "I've been eating carrots, and I still had to get glasses." Goodwin didn't have a response.

We've all been sold the bill of goods that carrots improve eyesight. Yet many faithful crunchers still find themselves squinting at street signs. So, do carrots actually help us see better?

Absolutely, according to ophthalmologist Rebecca Taylor, a clinical spokesperson for the American Academy of Ophthalmology and one of the most enthusiastic carrot champions around.

"There's a reason why these adages become adages: in large part because they're true," says Taylor. "When you eat a carrot, you're helping your body take a light source [and interpret it]. ... That makes food pretty darn important. That's the stuff that will keep me up at night, it's so exciting."

For eyesight, a carrot's nutritional punch comes from beta carotene, a "carotenoid" the body can convert into vitamin A, according to T. Michael Redmond, chief of the Laboratory of Retinal Cell and Molecular Biology at the National Eye Institute. Vitamin A enables opsin proteins to form in "cone cells" and rhodopsin protein to form in "rod cells" near the back of the eye. Cone cells process light in daytime conditions, while rhodopsin does the same in dim light. When light hits rhodopsin or cone opsins, it creates an electric impulse that travels to the brain for interpretation, helping us see.

Vitamin A deficiency can lead to night blindness, a condition in which people have difficulty adjusting their vision to low levels of light. "You go into a movie theater," Taylor explains, "and you see nothing. You can't process the little bit of light that's in there."

But night blindness is rare in the U.S. because vitamin A deficiency is rare in this country, according to the Centers for Disease Control and Prevention. That may help explain why carrot enthusiasts don't have superior eagle eyes compared with carrot detractors: Even without carrots, most people are getting enough vitamin A from other sources. (Sweet potatoes can provide even more vitamin A than carrots do, and dark leafy greens like spinach and kale are also vitamin A treasure troves.)

Enabling vision is not the same as improving vision. According to the online World Carrot Museum which exists the British government began touting carrots' health benefits during World War II to lure consumers away from rationed foods. Part of that campaign emphasized vitamin A's role in seeing in the dark. From the campaign, the myth grew that carrots improved already-healthy vision in the dark for example, during blackouts. That claim is false, according to Harvard Health Publications.

"Vitamin A will [help] keep your vision healthy; it won't improve your vision," Taylor says. "It won't keep you from needing glasses or contacts."

There's one more catch to vitamin A's powers. Because vitamin A is a fat-soluble vitamin, one needs to eat it with fat in order to fully absorb it and its benefits. Eating a raw carrot won't deliver as much vitamin A punch. "That's why you need to dip it in ranch," quips Taylor.

Because the process of converting beta carotene to vitamin A is somewhat inefficient, the National Eye Institute's Redmond says it's important to eat orange-colored foods frequently, as well as other foods with vitamin A, like dairy and fish.

To make nourishing the eye easier, Taylor recommends an ideal plate for healthy vision. Most of the plate would be taken up with a spinach and kale salad, red peppers, almonds and carrots on top good sources of vitamin A, E and C, all of which support eye health. An oily dressing helps with intake of fat-soluble vitamins A and E. (Some hard-boiled eggs would also add carotenoids that protect vision, as well as fat to help absorption.) On the side, kiwi and oranges provide vitamin C, and fish like swordfish or salmon offer zinc, another key ingredient for eye health.

But if that doesn't tickle your fancy, Taylor recommends a favorite from childhood. "I used to grow carrots with my daddy in the garden," Taylor says. "Try roasting carrots, parsnips, beets and fingerling potatoes with olive oil, rosemary and sea salt. ... Life just doesn't get better than that."

The Eyesight of Dogs – Good Herald

June 5th, 2017 6:43 am

Dogs are said to have the ability to see spirits and other paranormal entities unseen by man. In spite of this ability, vision is said to be the least sensitive sense of a dog. Our four legged friends are noted to have excellent hearing abilities and ultra sensitive noses but vision of dogs is inferior to that of its human friends.

So what kind of vision do dogs have? In spite of the similarity in genetics, dogs vision is different from humans. There was once a theory that dogs are living in a colorless world as they do not have the ability to see colors. Studies have proven that dogs can see colors but unlike humans that have trichomatic vision, dogs are noted to have dichromatic vision. Due to the dichromatic vision, dogs can only see some colors in the spectrum. Although not scientifically verified, dogs are believed to be able to see only shades of yellow and blue. Because dogs have fewer photoreceptor cones, mans best friends do not have the ability to distinguish red and orange colors.

Dogs see better in dim lights. This ability enables dogs to hunt and capture prey even in the night. Running in the dark at high speed would not be a problem to dogs because of their ability to see in the dark. Dogs make dependable guards not only because of their alert and protective nature but also because of this night time vision. Dogs can see better in the dark because they have the ability to dilate the pupils to let more light in.

Behind the dogs retina is a layer of reflective cells known as tapetum lucidum that has the function of reflecting light so that object the dog see in the dark would appear to be well lighted. Dogs have a more accurate and developed wide angle vision and peripheral vision. Dogs can detect the slightest movement even at a distance.

Dogs though find it hard to focus on the shape of object because they are known to have low visual acuity. These animals can detect movements at a distance but they would not be able to distinguish the shape of the moving object. Dog can see distant movements but objects that can be seen clearly by humans as far as 75 feet will be seen by dogs clearly if the object is only 20 feet away

Dogs indeed see the world in a different manner. Even with its inferior vision, dogs still have the qualities that make them endearing pets.

Now that you have read some about how dogs see. How about learning more about related topics like can dogs see colors? Sarahs Dogs answers this and many other questions about dogs.

Tour de Cure raises money for diabetes prevention – NEWS10 ABC – NEWS10 ABC

June 5th, 2017 6:43 am

SARATOGA SPRINGS, N.Y. (NEWS10) Cyclists took over the Spa City today for the 2017 Saratoga Tour de Cure.

Its one of the biggest events in the Capital Region to raise awareness for diabetes, taking place at Saratoga State Park.

All these cyclists here to raise money for diabetes research, the heroes of the event are the ones donning red.

To get that many people out here to show support its just overwhelming, said Randy Lewis of Clifton Park.

For the past seven years, Type 1 diabetes patient, Lewis has biked in Saratogas Tour de Cure.

His family was there to cheer him on.

Two years ago, his youngest daughter joined him on the ride, when she too was diagnosed with the disease.

Even though Ive watched my dad for 24 years, grow up with this disease, I honestly thought my life was over, said Sydnie Lewis.

Around 1500 cyclists, some riding as far as 100 miles came to show support at the event.

This was an emotional day for the Red Riders, people who are biking with Type 1 or Type 2 diabetes.

Crossing the finish line the first time, I did it, I had tears in my eyes, said Red Rider, Jen Edmiston.

Ben Heidbreder, a 13-year old trained for months to bike 50 miles with his dad.

Very proud of him he raised over $2,300 for diabetes research. Hes a champion rider, said Jeff Heidbreder of his son.

The event is something Sydnie and her father look forward to every year.

A reminder that life can be a tough ride, but youre never alone.

Theres so many people around you whether have it or they know someone or they just know of the disease. You have a huge support group no matter where you go, said Sydnie Lewis.

The goal is to raise $1.1 million and all proceeds go towards mission of American Diabetes Association, to prevent and to cure diabetes.

The Real World, Diabetes: As cameras roll, patients seek healing – STAT

ONTEGO BAY, Jamaica The man who boasts ofchanging the face of diabetes spreads his arms out wide, like the Christ the Redeemer statue, but in neon orange shorts and bare feet. He looks earnestly into the rolling camera.

Welcome to Reversed, he intones. Seated behind him are four of his disciples: Americans with type 2 diabetes whove flown to this tropical beach town to participate in a reality TV show marketed as a momentous opportunity to restore their health.Over eight days, theyll learn to exercise and eat right and bare their struggles in cathartic therapy sessions.

Their host, Charles Mattocks, is a smooth-talking, fast-moving entrepreneur, who has leveraged his family fame (his uncle was Bob Marley) and his own medical history (he uses diet and exercise, not insulin, to manage his diabetes) to set himself up as a guru to diabetics everywhere.

In an age where nearly 1 in 10 Americans has diabetes, a disease that can bring a lifetime of painful complications, patients are often desperate for miraculous turnarounds and theres a booming trade in supplements, diets, and self-help books that promise answers. Now, theres a TV show, too.

But Reversed is unlikely to prove anyones salvation.

The show,which will begin airing next month on cable, is at once a vehicle for Mattocks to proselytize his gospel of self-help, a marketing gambit by a pharma company thats running out of money, and a season-long advertisement for a luxury getaway at the sparkling resort where it was filmed.

The carefully choreographed, relentlessly upbeat atmosphere cultivatedunderthe Jamaican sun feels, well, unreal. Back at home, the shows stars like the viewers expected to tune in dont have in-house chefs to cook them healthy meals or mentors toguide them through yoga lessons.

Instead, theyre grappling with the stubborn realities and compounding challenges so common inpatients with chronic disease: deteriorating vision, nerve damage in their feet,congestive heart failure, hypertension, high body fat, the inability to work and even to walk. Just before the show, one of the participantslost her home; two others, a married couple, had been relying on food banks because they hadnt been able to afford to go to a grocery store for months.

Mattocks, the shows executive producer and creator, said he originally imagined Reversedas The Biggest Loser meets diabetes a reference to the long-running weight-loss competition on NBC.

But the participants on Reversed arent competing. Judging from the two days of filming that STAT observed, the show has more in common with the reality TV tradition of putting a bunch of strangers in a house together and seeing what happens. Call it The Real World: Diabetes, featuring burned kale chips, frowned-on cigarette breaks, and one participants dramatic decision to quit the show. (I dont think he was coming here for the right reasons at all, Mattocks told STAT, borrowing the ultimate reality TV insult.)

So it went for the weekof filming, as Mattocks put his cast members through a quirky array of activities:There were massages, just steps from the glittering Caribbean. Trust exercises featuring blindfolds, a basketball, and a banana. Lessons about natural remedies and medicinal plants on a day trip to a nearby farm.

Where are all the new diabetes drugs?

The camera operators scurried on instinct toward any hint of drama or tears. And they didnt always abide by the shows lessons for good health: At lunch one day, for instance, the diabetics ate seasoned vegetablesand sipped water while some crew members chowed on hamburgers and swigged from plastic bottles of Ting, a sugary citrus soda popular in the Caribbean.

The debut 10-episode season airs this summer on Discovery Life, a cable channel that specializes in medical programming starring real people, like The Boy With No Brain and Untold Stories of the ER. Last year it drew an average of 88,000 viewers a night during prime time, according to Valeria Almada, a spokeswoman for the channel. That ranks around 97th among networks, by one recent estimate of viewership.

The shows primary sponsor is MannKind, an insulin manufacturer thats in bad financial shape. Neither the show nor the company would say how much the sponsorship cost, but MannKind willget advertising spots for its struggling insulin inhaler, Afrezza, during commercial breaks and perhaps a brief mention of the product on the show itself.

Mattocks makes a point of telling STAT that hes not promising anyone they can reverse their diabetes. But he has, in the past, said exactly that.

And one of the sponsors of his show expressly promised that, too on camera. The company, OneCare, makes software to help patients manage their diabetes. And in exchange for his $6,000 sponsorship, CEO Gary Austin got to film a segment on set in Jamaica in which he explains to the cast members how his product works and tells them it will help them vanquish diabetes. Its possible, he told them. You can reverse it.

Three of thepatients Mattocks recruited for the show are convinced.I truly believe that within the next year I will no longer be called a diabetic, said Lisa Campbell, cheerful and effortlessly expressive in her Southern drawl.

I truly believe that within the next year I will no longer be called a diabetic.

Lisa Campbell, cast member

At 54, she has a litany of health complaints so severe, they forced into retirement from her career as an elementary school teacher four years ago. Her right foot isswollen and her ankle deteriorated from complications ofdiabetic nerve damage, known as neuropathy. Her vision is so blurred by retinopathy that she recently went blind for four months. To get around her home near Atlanta, she juggles between a wheelchair, walker, and cane.

Her 49-year-old husband, Roger, who joined her on set, has also been ravaged by diabetes: His left leg was amputated a few inches below the knee in 2015 and shortly before the filming, hedbeen diagnosed with congestive heart failure. Hed also developed a wound on his stump, but didnt tell his doctor because he suspected hed get hospitalized and have to skipthe trip, his first ever out of the country. He refused to miss it.

For patients with such advanced conditions, the hope of vanquishing diseaseis often an unrealistic one. And criticsworryReversedwill add fuel to aflourishingcottage industry premised on the idea that diabetes can be reversed.

You can manage it. You can control it. You cant reverse it. All this talk about reversing diabetes is a huge load of BS, said David Kliff, who has type 1 diabetes and publishes the newsletter Diabetic Investor.

To be sure, diabetics, like everyone else, can only benefit from a healthy diet and exercise. But theres no cure for diabetes. Type 1 diabetics cant quit their medicine, ever. And its extremely difficult for type 2 diabetics to do so, barring bariatric surgery. More than 2,200 such patients went on an intense diet and exercise regimen for a studypublished in 2012; after one year, only 11.5 percent were able to get off their medicine or get their blood sugar levels down to a certain threshold. After four years, just 7 percent were still there.

The whole reversed idea is: run screaming from the meds, said Amy Tenderich, a vocal patient advocate with type 1 diabetes. She worries that it might send the wrong message that if you continue to need medication or have to go on insulin, that you have failed.

Rick Phillips, a blogger with type 1 diabetes, shares that concern. He wrote inablog postthat he saw the TV shows title as an affront,the latest in a line of rhetoric that blames diabetics for their own disease. He cited recent comments from White House budget director Mick Mulvaney suggesting that American taxpayers shouldnt have to pay for the health care of the person who sits home drinks sugary drinks, and doesnt exercise, and eats poorly, and gets diabetes.

Mattocks did not take kindly to Phillipss critique of his show. Instead, he jumped on Twitter to call Phillips irrelevant and a clown. He added: Go be miserable some other place.

Mattocks insists that his show demonstrates its possible to slow the progress of the disease by reversing the way patients live their lives. He brought ahandful of experts onto the set to dispensetips about healthy habits, like how to read nutritional labels on breakfast cereal and how to tell if blood sugar levels are in a safe range.

He also sought to effectively scare his stars straight.Cast memberswere taken on a day trip to a dialysis center and a diabetes clinic in Kingston, Jamaicas capital, where they gaped at local patients in the advanced stages of diabetes.

You can manage it. You can control it. You cant reverse it. All this talk about reversing diabetes is a huge load of BS.

David Kliff, publisher, Diabetic Investor

Then there wasthescene filmed on Day 6: Participants had toput on baggy jeans, a long belt, and a big checkered shirt using only one hand a challenge meant to show them what daily life is like for patients whove lost limbs due to complications from advanced diabetes.

Roll sound. And action!

Margie Rivera, a bubbly grandmother from Tampa, Fla., went first, though she hardly needed the exercise to introduce her to the debilitating effects of diabetes. She lost her job as a dialysis technician a year ago after diabetic retinopathy eroded her vision. Just before filming began, another blow: She and her husband lost the house they had been renting with intent to buy.

Now, Rivera, 53, used her teeth to get the big shirt on. The pants went on easily enough until she struggled to lace the belt through the belt loops. God, this is hard, she murmured.

Next up was Jerome Hughes, a 43-year-old former retail manager from Atlanta whos quick to crack jokes. He had the bright idea of lacing the belt through the pants before putting them on. But he struggled mightily to get the bulky denim up over his black high-top shoes. As he grew more and more frustrated, Mattocks put a supportive arm over his shoulder and stepped in to help. Hughes struggled some more with the shirt, never getting it fully on, until Mattocks marched him away from the cameras. Both of their faces were creased with emotion.

Everyone on this show has been reversed, Mattocks later told STAT. Mentally, physically, emotionally, and even spiritually in a sense.

Mattocks, 46, is the opposite of what youd expect Bob Marley to be like. Tightly wound and usually multitasking, Mattocks buzzes around his set, always intentional and in control. He talks in real life in much the same way he does on camera: in a quiet and soothing voice, peppering his speech with phraseslike healing and journey and changing lives.

Mattocks only met his famous uncle twice, in brief encounters as a child. But the reggae legend has been his inspiration to make a difference in this world, he said.

He started out as a rapper and actor, then turned to cooking, branding himself as The Poor Chef demonstratinghealthy meals that could be made for just $7.

Mattocks was diagnosed with type 2 diabetes at age 38. His doctor gave him no guidance about lifestyle changes, he said. But on his own, he was determined to turn his health around. He stopped bulking up in the gym. He started walking, and then running. He stayed away from fried foods. He lost about 20 pounds in 2 1/2months.

Once-promising diabetes breakthrough comes unglued with a major retraction

Mattocks never went on insulin, and spent just nine months on metformin before his doctor advised him he could stop, he said.

That led to yet another career pivot: He became an evangelist for managing diabetes.

To that end, he vouched foran energysupplement aimed at diabetics. He wrote a childrens bookabout a furry diabetic bear named Charlie B. Marley. At one point, he even created a sugar-free chocolate bar infused with coconut oil and called it the Charles Bar.

Mattocks, who lives in Tampa, was careful when he talked to STAT about his journey: He made clear that he has not reversed his own diabetes but simply has it under control. But hes been much more aggressive about dangling the promise of reversal in other public outreach.

What if I told you that you could reverse your diabetes? he wrote in a 2015 op-ed.

And in the trailer for his documentary The Diabetic You: We did it, he says, We proved that diet and exercise, lifestyle changes, you can reverse diabetes. Then he breaks down with emotion, hand over his eyes, as the screen turns to black.

His swaggering confidence in his ability to tame a chronic diseasecomes across especially clearly in the recently released first issue of his new Reversed Magazinefor diabetics. Hes listed as chief editor.

Its in large part a tribute to himself, an Oprah magazine with lower production standards and more self-flattery.

Mattocks poses on the cover wearing a cowboy hat, bandanna, and a big-buckled belt. The tagline: Theres a new sheriff in town. Under that: Charles Mattocks changes the face of diabetes. An article inside says we must admire Charles Mattocks.

There were no auditions for Reversed.Mattocks picked the five stars of his show by plucking out old friends and friends of friends with an eye toward appealing to a broad audience. (Shes going to be great for the Latin American community, he said of Rivera, who was born in Puerto Rico.)

In the spirit of marriage boot camp reality shows, the producers put the Campbells on camera together as much as possible.Theyre a match of opposites Lisa lively and talkative; Roger, quiet and concise and that dynamic was on display duringon-camera therapy sessions, trust exercises, and cooking scenes.

With cameras rolling and the on-set dietician murmuring encouragement, the couple tore kale into strips, sprinkled on some olive oil, and gently massaged the oil into the leaves during one such scene. Lisa chattered happily about how much she loves preparing kale chips. Roger, who used to manage a paint store before his worsening health put him on disability, dutifully lowered the pan layered with kale stripsinto the oven.

(That was acting. I made them just for the camera. I do not like them, he later confessed to STAT.)

The crew moved on to the next shoot helping Rivera prepare healthy ice cream made from frozen strawberries and bananas.

Then a producer jumped in. Theyd forgotten about the kale chips!

Sure enough, they were burning in the oven. Much of the batch was charred to a crisp.

The setting was undeniably gorgeous: Most of the show was filmed in a 14-bedroom villanestled in lush green hills, with aglistening turquoise swimming pool out backand, far below, the ocean.

Still, the filming wasnt always easy for the Campbells. After Lisa took a tumble walking up an outdoor ramp, she mostly stuck to a wheelchair on set. For his part, Roger had experienced an alarming low blood sugar episode on Day 2of filming. He was often claustrophobic and felt too hot to sleep. And he needed frequent breaks to smoke. (Mattocks and the others gently chastised him about his cigarettesbut never asked him to stop.)

Despite it all, both he and Lisa made it to the shows graduation ceremony in the nearby resort town of Negril, where they donned black caps and gowns to acceptcertificates of accomplishment.

Just before the cameras started rolling, a crew member spotted a problem: a telltale green bottle of Ting, resting on a ledge. Get that soda out of the shot! he bellowed.

Mattocks is betting big on Reversed. Hes funding the project in part with his own savings, though he wouldnt specify how much. The shows total budget is very low, he said. Its more of a work of love, you know what Im saying?

To help pay the bills, Mattocks secured a few sponsors, including the struggling pharma company MannKind.

It was an unusual fit, given that Mattocks has long been a self-described outspoken critic of drugcompanies and their advertising. And, indeed, despite the sponsorship, the vibe on the Reversed setwas markedly anti-pharmaceutical.For a few days of filming, Mattocks brought in a health coach (a doctor who doubles as a naturopath and uses his website tosell supplements) to work with the cast members.

Everyone on this show has been reversed mentally, physically, emotionally, and even spiritually in a sense.

Charles Mattocks, executive producer

The diabetic stars of the show spoke in often bitter terms about their distaste for the drug industry and their desire to get off drugs for good.

We are naturally getting ourselves weaned off of this insulin, Lisa Campbell confidently told STAT.

In phone interviews nearly two months after returning home, three ofthe participants said they were on their way to reversing their diabetes. (Hughes, for his part, said he thought in terms of reversing his mindset.) They raved about their double-digit weight loss, their new diets packed with vegetables, and their reduced need for insulin. They were undaunted by the long odds they face in their quest to restore their health, saying that the mentoring they got on the show would give them an edge.

Even Roger Campbell, who hasnt managed to cut all of his unhealthy habits, speaks with pride about his progress. Sure, hes still smoking cigarettes, but hes down to half a pack a day, compared to a full pack a day before filming. And, yes, he hasnt given up soda completely, but hes replaced his bottle of Diet Coke every other day with a Coke Zero once a week. He credits those and other changes with cutting in half his use of insulin.

I actually feel like I am reversing my diabetes, Roger Campbell said. I hope to eradicate it completely.

Yet many of the challenges that shape their lives are unchanged: Roger Campbells congestive heart failure makes it hard for him to do much exercise. Lisa Campbell still struggles to see clearly and cooks her (newly healthy) breakfasts from her wheelchair. And money is still painfully tight. The couple remains reliant on food banks, where fresh produce can be limited.

Mattockss team recently released an pathos-heavytrailer for Reversed,which debuts at 7 p.m. on July 18.

Theres Rivera honing her arm muscles by stretching a resistance band. Hughes meditates, his eyes closed and hands clasped. Lisa Campbell splashesin the swimming pool. Gloved hands clean theopen wound on Roger Campbells leg stump. The cast member who quitwalksout the front door.

Five lives came for HOPE, banner text reads. Five lives will NEVER be the same.

New diabetes tech is coming. But will it make much difference?

Mattocks is already planning a second season. Another producer said theyrethinking about setting it in Latin America this time. Especially if next season we have a bigger budget and a bigger crew and a different location, I think we can rival any show out there, Mattocks mused.

In the meantime, hes begun marketing a new offering: a diabetes getaway, branded as the Reversed retreat, in the Jamaican resort house where the show was filmed.

For a week in September (just before the season finale of Reversed), instructors will be on hand to guide vacationers through the many of the same exercises the cast carried out for the cameras: early morning yoga. A juicing workshop. Group meditation.

The cost: up to $4,000 for the week, for those who spring for a private suite.

Airfare is not included.

Mild-to-moderate obstructive sleep apnea is associated with hypertension, diabetes – Medical Xpress

June 5th, 2017 6:43 am

Preliminary data from two studies suggest that mild-to-moderate obstructive sleep apnea is associated with an increased risk of developing hypertension and diabetes.

"We found that even mild sleep apnea was strongly associated with increased risk of developing hypertension by 4 times compared to individuals without sleep apnea," said principal investigator and lead author Alexandros N. Vgontzas, MD, Professor in the Department of Psychiatry at Pennsylvania State University College of Medicine. "Similarly, moderate sleep apnea was associated with increased risk of developing diabetes by almost 3 times compared to individuals without sleep apnea."

Results also show that these associations were strongest in young and middle-aged adults.

"In young and middle-aged adults, our findings suggest that early detection and treatment of mild-to-moderate sleep apnea is warranted in order to prevent future cardiometabolic disease," said lead author and postdoctoral scholar Yun Li, MD. "Given the stronger association of sleep apnea with metabolic abnormalities in this age group, emphasis should be placed on yearly monitoring of indices of metabolic symptoms and lifestyle interventions, such as weight control, healthy diet, regular exercise, and stress management."

According to the American Academy of Sleep Medicine, nearly 30 million adults in the U.S. have obstructive sleep apnea, a chronic disease that involves the repeated collapse of the upper airway during sleep. Common warning signs include snoring and excessive daytime sleepiness. While previous research has established that severe sleep apnea increases the risk of hypertension and diabetes, data regarding mild-to-moderate sleep apnea were unclear.

Both studies involved the Penn State Adult Cohort, a random general population sample of 1,741 adults. Participants completed a detailed medical history interview at baseline and were evaluated in a sleep center during an overnight sleep study. Those without hypertension or diabetes at baseline were followed up after 10 years.

The research abstracts were published recently in an online supplement of the journal Sleep and will be presented Monday, June 5, and Wednesday, June 7, in Boston at SLEEP 2017, the 31st Annual Meeting of the Associated Professional Sleep Societies LLC (APSS), which is a joint venture of the American Academy of Sleep Medicine and the Sleep Research Society.

TPR Lifeline: Diabetes And Brittle Bones – Texas Public Radio

June 5th, 2017 6:43 am

Diabetics are at risk of many serious side effects like heart trouble, nerve damage, kidney failure, blindness and amputations. Now, theres growing evidence the disease also puts people at greater risk of bone fractures. In todays TPR Lifeline, Bioscience-Medicine reporter Wendy Rigby talks to Dr. Ajeya Joshi of South Texas Spinal Clinic about the link between diabetes and brittle bones. Here is a transcript of the interview.

Rigby: This will be news to many people that having diabetes puts you at greater risk of brittle bones. Dr. Joshi, whats happening here to increase the risk of osteoporosis in type one and type two diabetics?

Joshi: Diabetes can affect practically every organ in the body. But now we know that it impacts bone. And if you think about diabetes as having too much sugar floating around in your bloodstream, well the bones have blood flowing to them. And so that sugar lands inside the bone matrix and corrodes it, if you will. So its not that you necessarily have less bone, but the bone that you do have is not of a good quality.

Rigby: So even if you get a normal bone scan, if you have diabetes you might be more at risk than someone without diabetes of fracture.

Joshi: Thats absolutely right. So we know that for diabetics we have to interpret their bone scans differently. And thats an understanding that we didnt necessarily routinely have five or ten years ago. So they are at risk at fracturing at bone scores that would be considered normal for other people.

Rigby: And what part of the body is most affected?

Joshi: You could see fractures like a wrist fracture in a 50-year-old female tennis player that might have fallen on the tennis court. Vertebral fractures are common, of the spinal column if you will in many of us. An important metric to follow in any medical office is how tall is our adult patient. And you see people losing height over time and that might be very important. And the final area thats common are shoulders and hips as we get into our seventies and eighties.

Rigby: What could you do for someone whos diabetic if you knew or you could tell that they were developing this side effect from the disease?

Joshi: We need to now recalibrate or adjust how we think of diabetics and think of an earlier threshold for helping them with their bone density studies when theyre low. For our diabetic patients whether its avoiding vascular problems like heart disease or stroke or dialysis from kidney failure, controlling your sugars is important for one more reason.

Rigby: This paper you recently published used data from University Health System. Where was it published and what audience were you trying to reach with this particular message?

Joshi: We were excited to be involved in this research which was published in the Journal of Immigrant and Minority Health.

Rigby: What did you find in particular about Hispanic diabetics?

Joshi: Being both diabetic and Hispanic raised the risk of fracture above the population that was diabetic but not Hispanic by one-and-a-half to two times. And that makes us say weve got to pay particular attention to these patients, communicate with them, educate them and their primary doctors and in the future, dedicate more attention and resources to understanding the background behind that.

Rigby: So people who are listening to this and saying I might fall into that category may wonder what happens if I have this? Is there something that can be done for me so that I can keep my bones strong?

Joshi: I would say that if you fall into a category where youre diabetic or Hispanic and diabetic, the key takeaways are being aware and being very attuned to lifestyle, exercise, sugar control and knowing that this is one more reason to control your sugars. And weight-bearing exercise is incredibly important. So there are factors like exercise which the bones love. Our bones being loaded. So the astronauts in space lose bone mass because theres no gravity. So walking is a great and important way to help your bone mass.

Rigby: Do you think more research will be done on this topic?

Joshi: I expect that we will be seeing a lot more attention devoted to this area in the years to come.

Rigby: Dr. Joshi of the South Texas Spinal Clinic, thank you so much for joining us.

Joshi: Its a pleasure to be here. Thank you.

How Diabetes Is Transforming People Into Real-Life Cyborgs – Geek … – Geek

June 5th, 2017 6:43 am

Diabetes both type 1, which is an incurable autoimmune disorder, and type 2 which is a lifestyle disease that can be reversed or cured are among the fastest-growing diagnoses in the world. Left untreated, they can cause life-threatening conditions and death. So its not surprising that the medical establishment is pumping resources into new methods of management.

What makes them worthy of talking about here on Geek is that technology is playing a major role. Todays diabetic is often wired up with Bluetooth sensors and custom software that turn them into virtual cyborgs with an awareness of their body chemistry that normal people cant match.

Heres a quick rundown of diabetes if youre not familiar with the condition. When you eat food, its split into three basic categories: carbohydrates, fats, and proteins. Carbohydrates, which are found primarily in plant products, break down into a sugar called glucose in your digestive system. That glucose is turned into fuel to power your mind and muscles.

The body does that conversion with a hormone called insulin, which is produced by beta cells in the pancreas. Type 1 diabetics dont make it at all their immune system destroys those beta cells for an as yet unknown reason. Type 2 diabetics make it, but for some reason its less efficient at breaking down glucose into energy.

When the body cant break down glucose, it has to get energy from other places mostly fat, but nothing is safe. That leads to a state of ketosis, where acids released from fats build up. Those acids can cause a wide variety of nerve and tissue damage.

So the life of a diabetic is basically monitoring their carbohydrate intake and then injecting an appropriate amount of insulin, based on a series of complex mathematical formulas, to match it. Too little and they go into ketosis. Too much insulin can drop their blood sugar dangerously low, which can lead to comas and death. Its a delicate tightrope that they walk every day.

The last few decades have seen advances in diabetes treatment that will blow your mind. To put them into context, lets rewind 50 years or so to look at what treatment was like.

Back in the day, a diabetic would wake up every morning and pee into a test tube. Theyd then drop a tablet into it that would change color to tell them what range their blood sugar was in high, normal or low. Theyd then take a single injection of long-lasting time-release insulin that would do for the entire day and hope for the best. When they were done, theyd take the syringe, boil it on the stove to sterilize it and put it back for tomorrow.

Needless to say, the life expectancy for diabetics was pretty short. Without a way to detect highs or lows, their bodies were at the mercy of a variety of factors and many died.

So there were two problems facing diabetics: being able to monitor blood sugar and being able to deliver the appropriate amount of insulin, no more, no less.

Monitoring got easier with the invention of the fingerprick blood glucose monitor in 1981. A drop of blood is introduced to an enzyme, and then an electrical current is passed through it. The number of electrons the sample loses correlates to the amount of glucose present in the sample. This allowed for significantly more precision, delivering a numerical representation of the patients current blood sugar.

That was coupled with the development of faster-acting insulin, so diabetics could treat highs as they happened. The next wave of diabetes care required them to be a more active participant in their management, checking glucose throughout the day and making adjustments as needed. As cool as this was, technology was about to get involved in a big way.

Fingerprick glucose is accurate but requires the diabetic to go through a process every time they want to check (and only works when theyre awake). The threat of low blood sugars at night is a very real one, as glucose levels can drop quickly. An accidental scientific discovery in the mid-1990s helped change the lives of diabetics around the world.

Researchers were experimenting with the bodys cell fluid in the skin and discovered that it basically mirrors the blood glucose level with about a 15-minute delay. In 1999, MiniMed got FDA approval for the first continuous glucose monitor an electrode thats inserted into a diabetics skin that transmits a reading every five minutes without the need to draw blood. Now patients could get real-time feedback on their blood sugar throughout the day. Those early sensors were good for about three days before the bodys immune system rejected them, but modern ones can go for a week or more before theyre changed.

Monitoring that accurate is all well and good, but a diabetic would still need to give themselves an injection to bring high blood sugar down. However, an earlier invention made that process significantly easier. In 1973, Dean Kamen (inventor of the Segway) debuted the worlds first wearable insulin pump, a device that could dose any amount of insulin to a diabetic through a cannula, or small tube, that attached to the body. This gave diabetics even more control over their treatment, enabling them to microdose and control exactly how much of the hormone they receive.

Pumps have advanced significantly over the last decade, with one the Omnipod not needing a tube at all, but affixing directly to the skin and communicating wirelessly with a control device. Patients who manage diabetes with these devices are uniformly in better condition, and even though only one in a thousand diabetics currently uses a pump, that number is rising.

The next step is the artificial pancreas, a device that combines the two into one. These have passed clinical trials and are being rolled out slowly by endocrinologists around the country. Using complex algorithms, they monitor blood glucose and treat it at the same time in a closed-loop system, also administering glucose when blood sugars are too low. Early results are incredibly positive. Like existing pumps and CGMs, they still have to be changed out regularly, but the system marks a significant advance in treatment.

The future of diabetes is even more exciting. Companies are working on insulin that doesnt have to be injected, but rather is absorbed through the skin with a sound-activated patch. Another brand can be inhaled before a meal. Google is collaborating with contact lens manufacturer Alcon on a lens that measures blood sugar through the eye.

So if you see somebody walking around with some little gray boxes attached to their arms or stomach, its highly possible that theyre toting around a cyborg pancreas, wired into the cloud and keeping them healthy.

World-First Trials Have Been Launched to Treat Parkinson’s And Blindness With Embryonic Stem Cells – ScienceAlert

June 5th, 2017 6:42 am

In a world first, surgeons in the Chinese city of Zhengzhou are planning to inject stem cells derived from human embryos into the brains of patients with Parkinson's disease with the aim of treating their debilitating symptoms.

Meanwhile, another medical team in the same city is aiming to target vision loss using embryonic stem cells (ESC) to replace lost cells in the retina, marking a new direction in China in the wake of major changes in how the country regulates stem cell treatments.

While similar treatments on Parkinson's patients have already been tested in Australia, those trials relied on cells taken from eggs that were forced to divide without first being fertilised in an effort to circumvent any ethical concerns.

Stem cells are a little like blank slates that are yet to take on a specific task. If you rewind the clock on any of your body's tissues, its cells will become less specialised, until you're left with a cell with a lot of potential to become nearly anything.

In the case of both kinds of embryonic stem cells, divided egg cells are subjected to various treatments to encourage them to develop into replacement cells that could treat a condition in a recipient.

The symptoms of Parkinson's disease are largely caused by a loss of nervous tissue deep inside the brain in an area called the basal ganglia.

Losing those cells means a loss of a neurotransmitter called dopamine, and with it a lower ability to control nervous impulses that would prevent muscles in the extremities from activating.

In the case of a condition called macular degeneration, damage to a layer of tissue called the retinal pigment epithelium at the back of the eye causes the light-catching cells above it to die.

By turning ESC into cells that can naturally develop into the tissues that have deteriorated such as the precursors to neurons that can produce dopamine, or into retinal tissue and then injecting it into the target site, the researchers hope to improve the lost functions.

Not everybody is convinced of the success of trials such as those being done in China and last year in Australia.

A stem cell biologist from the Scripps Research Institute in California, Jeanne Loring, believes the choice of cell used in both Parkinson's disease trials won't be specialised enough to match expected results.

"Not knowing what the cells will become is troubling," Loring told David Cyranoski at Nature.

But the research team in China remains confident in its decision.

Qi Zhou from the Chinese Academy of Sciences Institute of Zoology in Beijing is the stem cell specialist leading both sets of ESC trials, and says four years of animal trials conducted on monkeys have so far showed promising results.

"We have all the imaging data, behavioural data, and molecular data to support efficacy," Zhou told Nature.

He also claims the team conducting the Parkinson's trial have been selective with their potential candidates, choosing patients who will have the least chance of rejecting the ESCs from the cell bank.

In 2015, China introduced tough new regulations to deal with the growing problem of 'rogue clinics' offering stem cell treatments without due record keeping or process, making it hard to evaluate safety, or even the types of cells used in the treatments.

The changes are set to improve the ethics and safety of stem cell treatments by enforcing the use of cells through a regulatory body, ensuring informed patient consent, and permitting treatments only through authorised hospitals.

Time will tell if the regulations can be enforced, but for stem cell researchers, the changes are positive.

"It will be a major new direction for China," stem cell scientist Pei Xuetaotold Nature.

If the results are as good as the teams in Australia and China predict, it could also set new standards for the world.

The Canadian biotechnology business is a picture of good health.

On Friday, management of Vancouver-based cancer therapy developer Zymeworks Inc. rang the bell on the Toronto Stock Exchange, five weeks after its stock debuted in a $59-million (U.S.) initial public offering in Canada and on the New York Stock Exchange. It was by far the largest biotech IPO on a Canadian exchange in a decade and came on the heels of one of the largest stock offerings ever by a Canadian biotech firm, after dual-listed lupus-drug developer Aurinia Pharmaceuticals Inc. raised $150.5-million in March.

Choosing a Biotechnology College in Canada

How you start your career depends on where you have studied, to a great extent. The biotechnology programs that have met the national technology accreditation requirements established by the Canadian Council of Technicians and Technologists (CCTT) and the Canadian Technology Accreditation Board (CTAB) offer better placement opportunities.

It is important to ask the following questions before enrolling into a biotechnology college or course in Canada:

Is the program accredited by the Canadian Technology Accreditation Board (CTAB)? Is the program affiliated to the Canadian Council of Technicians and Technologists (CCTT)? Does it combine laboratory work with classroom learning? Does the college allow you to apply for certification through the Ontario Association of Certified Engineering Technicians and Technologists for using the designation: Certified Technician? Does the program incorporate training in Occupational Health and Safety, HACCP, GMP or WHMIS to industry standards? Does the prospective college allow you to apply academic credits earned during the program to study for an advanced program? Does the program incorporate independent microbiology projects?

A program is worth considering if answer to all these questions is a yes. Centennial Colleges two-year post-secondary program in biotechnology meets all the above mentioned criteria. In addition, a special feature of the program is the project approach. It allows students to design independent projects to help them enhance their problem-solving and research approach. With this, the program is also a repeat recipient of the College Presidents Academic Program Recognition Award for outstanding student satisfaction.

Studying Biotechnology

The post-secondary diploma program in biotechnology typically runs for two years and covers a wide range of subjects. Students develop strong fundamentals in chemistry, inorganic chemistry, mathematics for applied science, and statistics for applied science, biotechnology, microbiology and technical report writing.

With this, they also study occupational health and safety, microbiology techniques, food microbiology, analytical chemistry, pharmaceutical microbiology and recombinant DNA technology. The program also lays a strong emphasis on computer education and covers microcomputer applications for technology A.

Enrolling in a Biotechnology Program

Students interested in applying for this program need to submit:

Secondary school diploma or equivalent English Grade 12 C or University or equivalent scores Mathematics Grade 11 M or 12 C or University or equivalent scores

Students currently in high school can also apply for this program. Their grades will be automatically transferred to the college.

Studying Biotechnology And Microbiology For Career Building – Good Herald

June 5th, 2017 6:41 am

Science has multiple wings and streams and studying one of them and specializing in it can open up various career prospects for the candidates. A couple of such streams that are gaining importance and popularity are biotechnology and microbiology. Both are integral parts of biological science and both have their respective uses. Pursuing a graduation or masters degree in the field may prove extremely rewarding for the users. Many students these days are pursuing the BSc Biotechnology and higher degrees in search of building up their career graph.

Understanding Biotechnology

Biotechnology involves the use of genetic as well as biochemical processes related to the living organisms for using them for humans. There are numerous genetically modified crops in the field of agriculture and there are also multiple genetically modified vaccines in the field of healthcare and medications. In some of the leading science colleges in Dehradun particular emphasis is given to the application of the principles of biotechnology in DNA applications and cell regulation in human anatomy. While the BSc degrees offered by these colleges include basic applications in the field the MSc Biotechnology degree offers higher levels of use of the biochemical processes and their impact studies.

Work Placement and Laboratory Works

Students seeking to obtain the MSc Biotechnology degree may not find the task easy enough. There are very strong optional work placements involved and the course also includes high degrees of laboratory works. This ensures practical experience induction in the student preparing him or her to be strong enough to face all the challenges that come their way. Thus the courses are intelligent combination of theories and practices.

Biotechnology Course Components

Course components for the students studying for obtaining graduation or masters degree in biotechnology include biology, chemistry, and mathematics. Physics is not normally included but students can separately study physics and even go up to the level of passing MSc Physics. In degree courses there are no majors. Students may however opt to specialize in a subject and choose the honors course in it. Taking honors has two benefits. First it can enhance job prospects and second it would make entry into the MSc course easier.

Job Prospects in the Field

People with graduate or masters degree in biotechnology get job opportunities in a host of industries. These are pharmaceuticals, environment, agriculture, horticulture, research, and forensic science among others. Job opportunities are available in both public as well as private sectors. Consulting services, academes, research organizations and NGOs are other major job sources.

Study of Microbiology

An important wing of biotechnology is microbiology that deals with organisms in microscopic sizes. They include bacteria, viruses, protozoa and algae as well as fungi affecting the life of human beings. Studying their characteristics, impact on human anatomy and remedial solutions constitute the basic features of the MSc Microbiology.

Biotechnology is not a new invention and has been in use for over six thousand years. The technology has been used to prepare foodstuff like bread and cheese, for preservation of dairy products and also for fermenting beer. Candidates need a good college to pursue their course of BSC or MSc Microbiology or any other wing of the biotechnology. To choose the right academy the need information and a qualitative site can provide the required information for them.
