Fasting extends reproductive life span

However, a new study suggests that in case of nematode worms, this does not hold true.

According to Marc Van Gilst and colleagues at the Fred Hutchinson Cancer Research Centre, during starvation, sexually mature adult worms stop ovulating and the germline component of their reproductive system — the sex cells, including mature and maturing eggs — dies off and leaves behind nothing but a few stem cells. However, once normal food conditions resume, the conserved stem cells can produce a brand new crop of sex cells, complete with youthful and fertile eggs. This turning back of the reproductive clock all takes place in tiny C elegans soil worms that are up to15 times older than normally fed worms in their reproductive prime.

“For many, it has been assumed that cells and organs remain relatively stable during periods of starvation or caloric restriction,” said Van Gilst.

Marriage helps in beating cancer
They may joke that marriage raises their blood pressure but married people have the best chance of surviving cancer, a new study has found. What’s more, those going through the pain of separation have the poorest survival rates, the study claimed.

According to the study’s authors, the results suggest that the stress associated with marital separation may compromise an individual’s immune system and lead to a greater susceptibility to cancer.

Research has shown that personal relationships have a significant role in physical health-specifically that good relationships are beneficial and poor relationships are deleterious.

High insulin levels linked to cancer
Researchers have found that high insulin levels might increase the risk of developing prostate cancer.

Lead researcher Demetrius Albanes, of the Nutritional Epidemiology Branch, Division of Cancer Epidemiology and Genetics at the National Cancer Institute in Bethesda, examined the relationship of the level of serum insulin and glucose, as well as surrogate indices of insulin resistance, to the development of prostate cancer.

The study showed that elevated insulin levels in the normal range appear to be associated with an increased risk of prostate cancer. When subjects in the second through fourth quartiles of serum insulin concentration were compared with those in the first or lowest quartile, higher insulin levels within the normal range were associated with statistically significantly increased risk of prostate cancer.

H2O2 helps in healing wounds
A study on the zebrafish suggests that the body might be using hydrogen peroxide as an envoy that marshals troops of healing cells to wounded tissue.

Timothy Mitchison of Harvard Medical School and Thomas Look of Dana Farber Cancer Institute have observed that when the tail fins of these creatures are injured, a burst of hydrogen peroxide is released from the wound and into the surrounding tissue.

The researchers say that teams of rescue-working white blood cells respond to this chemical herald, crawl to the site of damage, and get to work.
