Woman’s Ear Regrown In Her Forearm | Singularity Hub | Longevity science | Scoop.it

Doctors at Johns Hopkins University were able to give a woman her ear back by first growing it beneath the skin of her forearm.

 

The doctors reconstructed an incomplete ear using the limited amount of skin she had left on her face and neck for reconstruction. The ear was then planted beneath the skin of her forearm.

 

Cartilage from Walter’s rib cage, and skin and arteries from other areas of her body were placed in her arm...

Scientists announce new treatment for type II diabetes

Scientists announce new treatment for type II diabetes | Longevity science | Scoop.it
Scientists have announced a new method of treating and preventing type II diabetes.

 

The new treatment focuses on VEGF-B, a protein within the body that affects how fat is transported and stored. Using an antibody/drug known as 2H10, the scientists were able to block the signaling of VEGF-B in mice and rats, which subsequently kept fat from accumulating in the “wrong” areas of the animals – namely their muscles, blood vessels and hearts.

 

The paper for this researched was published in Nature on Sept 26:

It's Not Just Salt: Sugar Boosts Blood Pressure, Too

It's Not Just Salt: Sugar Boosts Blood Pressure, Too | Longevity science | Scoop.it
Reducing sugary drinks, even just a few ounces a day, reduces your risk of blood pressure problems.

 

A study in 2010 found that decreasing the intake of sugar-sweetened beverages (already-known culprits of weight gain) lead to a reduction in blood pressure.

 

Elevations in blood pressure increase the risk of heart disease and stroke. Even a slight reduction, which could be achieved by cutting out 12 oz of sugary beverages per day, can make a difference in terms of heart health risk.

 

Scientists aren't certain why sugar affects blood pressure. One possible explanation is that sugar irritates the artery walls, which may prompts an increase in pressure.

Yasmeen Lee's comment, April 8, 2013 12:08 PM
I think I will apply these helpful eating tips the next time I am grocery shopping or eating at a restaurant. It is so hard to eat healthy food these days when fast food is more convenient and less expensive. Almost every time I go out with my friends I am dragged to the nearest burger joint or ice cream shop. Now that I am more health conscious I have decided to take matters into my own hands. While I cannot stop my friends from making poor eating habits I know that I can fix mine. For example, I never skip breakfast because it is the most important meal that helps you get your day started. I was surprised that by eating fruit and protein each morning, I was less hungry and more focused. In addition, instead of depending on the vending machine to give me a bag of chips or candy, I now plan what snacks I will bring and how much I should eat. I have replaced my usual tea and sugary beverage with water. When I was younger I always thought vegetables were tasteless and gross. Now that I am starting to cook for myself I have found ways to incorporate them into my diet without sacrificing taste. The next time my friends invite me to go eat out I will make sure to plan ahead and look for the healthiest option available.

UK, Japan scientists win Nobel for adult stem cell discovery

UK, Japan scientists win Nobel for adult stem cell discovery | Longevity science | Scoop.it

Scientists from Britain and Japan shared a Nobel Prize on Monday for the discovery that adult cells can be transformed back into embryo-like stem cells that may one day regrow tissue in damaged brains, hearts or other organs.

 

John Gurdon, 79, of the Gurdon Institute in Cambridge, Britain and Shinya Yamanaka, 50, of Kyoto University in Japan share the $1.2 million Nobel Prize for Medicine, for work Gurdon began 50 years ago and Yamanaka capped with a 2006 experiment that transformed the field of "regenerative medicine" - the search for ways to cure disease by growing healthy tissue.

Rapid genomic deep-sequencing testing pinpoints newborns' genetic diseases in a few days

Rapid genomic deep-sequencing testing pinpoints newborns' genetic diseases in a few days | Longevity science | Scoop.it

A faster DNA sequencing machine and streamlined analysis of the results can diagnose genetic disorders in days rather than weeks. 

 

Up to a third of the babies admitted to neonatal intensive care units have a genetic disease. Although symptoms may be severe, the genetic cause can be hard to pin down. Thousands of genetic diseases have been described, but relatively few tests are available, and even these may detect only the most common mutations.

 

Whole-genome sequencing could test for many diseases at once, but its cost, the complexity of the results and the turnaround time are prohibitive. In what they hope will be a prototype for other hospitals, a research team led by Stephen Kingsmore at Children’s Mercy Hospital in Kansas City, Missouri, has implemented a much faster, simpler system for finding relevant mutations in whole-genome sequences that is designed for physicians without specialized genetic training.

 

These kinds of innovation will help more hospitals bring sequencing into clinical care, says Richard Gibbs, director of the human genome sequencing centre at Baylor College of Medicine in Houston, Texas. “A lot of people are going to realize from this that the future is now.”

 

Sequencing has been used before to pinpoint the cause of mysterious diseases. In 2011, Gibbs led a team that sequenced 14-year-old twins with a neurological movement disorder and found a way to improve their treatment2. In another instance, whole-genome sequencing suggested that a mysterious case of severe inflammatory bowel disease had a genetic cause and could be relieved through a bone marrow transplant3. But both these examples required several weeks and a team of experts to resolve. The Children’s Mercy Hospital plans to offer routine sequencing in the neonatal intensive care unit by the end of the year.

 

To order a test, physicians will choose terms from pull-down boxes to describe the infant's symptoms. Software then compiles a list of potential suspect genes. After the genome is sequenced, the software hunts for and analyses mutations in only those genes, which allows it to compile a list of possible causative mutations more quickly. The team had early access to a new DNA sequencing machine from sequencing company Illumina, based in San DIego, California, that could generate a whole genome within 25 hours. The entire process, from obtaining consent to preliminary diagnosis, took 50 hours, not counting the time taken to ship DNA samples and computer hard drives between Illumina's lab in the UK, where the DNA sequencing was carried out, and the hospital, where analysis was conducted. Kingsmore estimates that the cost of sequence and analysis is $13,500 per child, including costs to verify variants in a laboratory certified to perform clinical tests.

 

Fast sequencing cannot diagnose all genetic diseases. Current sequencing technology tend to overlook mutations such as duplicated genes, for example. Nonetheless, deep sequencing will be able to provide diagnoses for many cases that would otherwise remain harrowing mysteries.

Does Fructose Fuel Cancer? - Vital Choice

Does Fructose Fuel Cancer? - Vital Choice | Longevity science | Scoop.it

Scientists reviewed the evidence that links fructose to cancer, and affirmed that “Fructose intake is associated with increased risk of pancreatic and small intestinal cancers, and possibly others … [it] is associated with more aggressive cancer behavior and may promote metastasis.” (Port AM et al. 2012)

 

The average American consumes more than 65 lbs of high fructose corn syrup per year. Though there is some fructose in fruits, for example, the most potent and dangerous sources are processed food and sweetened drinks.

Vitamin D Levels and Risk of Heart Disease: a Statistical Link

A large Danish study found a strong statistical link between low blood levels of vitamin D and increased risk of heart disease and death.

 

The population study measured baseline vitamin D levels, then followed up over 29 years. The researchers also performed a meta-analysis of 35 additional studies.

 

The team cautions that this is not a causal proof. However, there is a strong link. This could mean either that low vitamin levels indicate poorer health status, or that vitamin D levels do directly affect heart health.

 

The official conclusion of the study "We observed increasing risk of ischemic heart disease, myocardial infarction, and early death with decreasing plasma 25-hydroxyvitamin D levels."
