Health New Round Up – 5/11/2013

in-the-news

So Guy Fawkes night is here! WOW! The march of Christmas is upon us. I went for a birthday meal for some one last weekend at a holiday camp and as I walked in I was greeted by a six foot tall Santa!!! In my opinion this is far too early to start Christmas! (1st of November). I like Christmas and I love the build up (most of the time the build up is more exciting than the day itself) but I think there should be a rule that no Christmas decorations should be allowed before December 1st. That way we protect the Christmas spirit and on the 1st of December BOOM! The magic begins! In recent years but the time December 1st rolls around I’m sick of Jingle bells! So what does all this have to do with the Health news round up? Absolutely nothing.

So here we go, my pick of note worthy news and info from the world of health. I have picked through the propaganda and rubbish to show what I find interesting and informative and I hope you do to.

Health News update 16th of June 2013

in-the-news

The world of health is full of news as usual and I have shared some of my best stories from various sources below.
Stories from Natural News range from B Vitamins slowing the progression of Alzheimers to proof that being kinky in the bedroom is good for the mind!!! GreenMedInfo shares the health benefits of the much used but often overlooked Orange, and Turmerics benefits on Alzheimers disease. Science daily shares a study once again confirming why we all need to be reduce our sugar consumption and new study’s show how sugar can damage the heart!

Potential Way to Protect Neurons in Parkinson’s, Alzheimer’s, ALS

ScienceDaily (Mar. 14, 2011) — Cell biologists pondering the death of neurons — brain cells — have now shown that by eliminating one ingredient from the cellular machinery, they prolonged the life of neurons stressed by a pesticide chemical. The finding identifies a potential therapeutic target to slow changes that lead to neurodegenerative disorders such as Parkinson’s and Alzheimer’s diseases.


The researchers, from The University of Texas Health Science Center San Antonio, found that neurons lacking a substance called caspase-2 were better able to withstand pesticide-induced damage to energy centers known as mitochondria.

Master switch

Caspase-2 appears to be a master switch that can trigger either cell death or survival depending on the amount of cellular damage, the team found. Neurons that lacked caspase-2 showed an increase in protective activities, including the efficient breakdown of obsolete or used proteins. This process, called autophagy, delays cell death.

“This research shows, for the first time, that in the absence of caspase-2 neurons increase autophagy to survive,” said study co-author Marisa Lopez-Cruzan, Ph.D., investigator in the cellular and structural biology department at the Health Science Center.

Role of energy centers

Evidence suggests that mitochondrial dysfunction plays an important role in neuronal death in conditions such as Parkinson’s disease, Alzheimer’s disease, amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease) and Huntington’s disease.

“Identifying initiators in the cell death process is important for determining therapeutic approaches to provide the maximum protection of neurons during neurodegenerative conditions,” said senior author Brian Herman, Ph.D., vice president for research and professor of cellular and structural biology at the Health Science Center.

Young adult mice

The team studied neurons from young adult mice. This was intended to model the early changes that take place in neurodegenerative diseases.

The research is in the March 11 issue of the Journal of Biological Chemistry.

Dr. Lopez-Cruzan, director of Dr. Herman’s laboratory, came up with the idea that caspase-2 protects cells from mitochondrial stress. Meenakshi Tiwari, Ph.D., postdoctoral fellow, expanded upon the initial work and is first author of the paper.

The work was supported by the National Institute on Aging and is part of a second National Institutes of Health MERIT award to Dr. Herman.
