New rapid gene test for mitochondrial disease
A genetic test has been developed, providing a rapid diagnosis of mitochondrial disorders to identify the first patients with inherited mutations in a new disease gene. The team of medics and scientists working on the study have identified mutations in a gene, known as TMEM126B, involved in energy production in patient's muscles. (Source: ScienceDaily Headlines)

Cloning for Medicine: the Miracle that Wasn’t
By Editor, Sunday Times, Sri LankaJul 5 2016 (The Sunday Times - Sri Lanka)PARIS, AFP – When Dolly the cloned sheep was born 20 years ago on July 5, many hailed mankind’s new-found mastery over DNA as a harbinger of medical miracles such as lab-grown transplant organs. Others trembled at the portent of a “Brave New World” of identical humans farmed for spare parts or as cannon fodder.As it turns out, neither came to pass.Human cloning — complicated, risky and ethically contentious — has largely been replaced as the holy grail of regenerative medicine by other technologies, say experts.“It has ...

MENDing The Alzheimer's Brain
Alzheimer's Disease is a degenerative disease of the brain that is currently thought to affect nearly 44 million people in the world. In the United States alone, over 5 million people suffer the illness. It is estimated that, at current rates, that number will grow to more than 17 million by 2050. It is an expensive illness. The Alzheimer's Association predicts that the disease will cost our country 236 billion dollars in 2016. However, the human cost of the illness is incalculable. Despite the efforts of many, there has been no cure for the disease. At present, no one medication works to either prevent it or substanti...

Persian Gulf War Veterans Still Suffering Serious Health Problems
This year marks the 25th anniversary of the Persian Gulf War.
It was fought in late 1990 through early 1991 by a U.S.-led coalition of 34 countries against Iraq in response to Saddam Hussein's invasion of Kuwait.
It also was the first U.S. war to be waged after the advent of the 24-hour cable television news cycle.
The conflict was accompanied by memorably intense and round-the-clock coverage on CNN.
But there've been few recognitions of the war's 25-year milestone on the cable news networks, let alone in broadcast or print media.
For David Winnett, a Gulf War combat veteran who climbed the ranks from private to capta...

Long Distance Running Effects On Your Health
Long distance running is becoming more and more popular. Close to two million people every year drag themselves across the finish lines. And that’s just in half marathon races. Runners in these 13.1 mile events have increased six-fold over the past 25 years.
All these amateur athletes think they’re getting really healthy as they work themselves up to full marathons. But the truth is they are cutting years off their life.
You can see it for yourself if you stand at the finish line of any race. The hardcore runners look terrible. They look gaunt and malnourished. They are hunched over and have a stif...

Mobilizing mitochondria may be key to regenerating damaged neurons
(Rockefeller University Press) Researchers at the National Institute of Neurological Disorders and Stroke have discovered that boosting the transport of mitochondria along neuronal axons enhances the ability of mouse nerve cells to repair themselves after injury. The study, 'Facilitation of axon regeneration by enhancing mitochondrial transport and rescuing energy deficits,' which has been published in The Journal of Cell Biology, suggests potential new strategies to stimulate the regrowth of human neurons damaged by injury or disease.

[Perspective] The cancer predisposition revolution
Studies of rare cancer predisposition syndromes often lead to the identification of genes critical to carcinogenesis. In 1969, Li and Fraumeni described a constellation of various cancers in the family members of four unrelated children who were diagnosed with soft tissue sarcomas (1). They posited that the cancers best fit an autosomal dominant pattern of inheritance, attributable to a genetic defect. At that time, cancer was not generally thought of as a genetic disease. Their hypothesis set the stage for establishing germline mutations in the tumor suppressor gene TP53 as the underlying genetic event in Li-Fraumeni synd...
