Researchers led by Honglei Chen, MD, PhD from National Institute of Environmental Health Sciences looked at the length of telomeres, DNA sequences at the end of chromosomes that shorten as cells replicate and age.
The ageing and lifespan of normal, healthy cells are linked to the so-called telomerase shortening mechanism, which limits cells to a fixed number of divisions. During cell replication, the telomeres function by ensuring the cell's chromosomes do not fuse with each other or rearrange, which can lead to cancer. Elizabeth Blackburn, a telomere pioneer at the University of California San Francisco, likened telomeres to the ends of shoelaces, without which the lace would unravel.
With each replication the telomeres shorten, and when the telomeres are totally consumed, the cells are destroyed (apoptosis). Previous studies have also reported that telomeres are highly susceptible to oxidative stress.
Dr Chen and his co-workers noted that telomere length may therefore be a marker of biological ageing, and that multivitamins may beneficially affect telomere length via modulation of oxidative stress and chronic inflammation.
Genetic analysis of the new H1N1 virus reveals that three of its genes, including the hemagglutinin gene (the H in H1N1), originally came from the 1918 Spanish influenza virus and have been present in pigs ever since. The genes have not changed much, likely because pigs do not live long enough to get reinfected with the same virus,

Drink from plastic bottles can raise the body’s levels of a controversial ‘gender-bending’ chemical by more than two thirds, according to tests.
Experts have been concerned about the possible health effects of bisphenol A (BPA) - an everyday chemical used in many plastic food and drink containers and tins as well as clear baby bottles - which is officially classified as toxic in some countries.
A study found that participants who drank for a week from polycarbonate bottles showed a 69 per cent increase in their urine of BPA, which mimics the female sex hormone oestrogen.
A 66-year-old woman with terminal cancer has become the first person to die under Washington state's new assisted suicide law, an advocacy group said Friday. Linda Fleming, of Sequim, died Thursday night after taking drugs prescribed under the ''Death with Dignity'' law that took effect in March, said Compassion & Choices of Washington.
The organization said Fleming was diagnosed last month with advanced pancreatic cancer. She would have had to have been diagnosed by two doctors as terminal in order to qualify for assisted suicide.
American Academy of Environmental Medicine Calls for Immediate Moratorium on All Genetically Modified Foods
AAEM’s position paper stated, “Several animal studies indicate serious health risks associated with GM food,” including infertility, immune problems, accelerated aging, insulin regulation, and changes in major organs and the gastrointestinal system. They conclude, “There is more than a casual association between GM foods and adverse health effects. There is causation,” as defined by recognized scientific criteria. “The strength of association and consistency between GM foods and disease is confirmed in several animal studies.”
Virtually all "protein bars" on the market today are made with soy protein. Many infant formula products are also made with soy protein, and thousands of vegetarian products (veggie burgers, veggie cheese, "natural" food bars, etc.) are made with soy protein. That soy protein is almost always described as safe and "natural" by the companies using it. But there's a dirty little secret the soy product industry doesn't want you to know: Much of the "natural" soy protein used in foods today is bathed in a toxic, explosive chemical solvent known as hexane.
A Minnesota judge has ruled that a 13-year-old boy with a highly treatable form of cancer must seek conventional medical treatment over his parents' objections.
"I feel it's a blow to families," he said. "It marginalizes the decisions that parents face every day in regard to their children's medical care. It really affirms the role that big government is better at making our decisions for us."
