In Europe, although less frequent, estimates point to an expense of 1,500 million euros in these products. Despite a rising world market, experts warn that many supplements are unnecessary and even, in some cases, dangerous. Read the rest of this entry »

High doses of this mineral may cause undesirable effects on health

Although the selenium content is variable depending on soil cultivation, the main dietary sources are nuts, fish, whole grains (bread, pasta, rice), wheat germ and sunflower seeds. In recent years, has been assigned a preventive role against various diseases, especially for some types of cancer, including prostate and stomach cancer. Thus, supplementation with this element is, in some areas, habitual. Read the rest of this entry »

A program called ‘Canine Hereditary Cancer Consortium’ has the objective of studying the natural occurrence of cancer in dogs, to find any indication of why this disease develops in pets and people.

The researchers analyzed DNA obtained from saliva of dogs to find the root of some of the rarer cancers.

“Rare diseases in humans also occur in dogs,” said Mark Neff, director of the program. “By studying the DNA of dogs, hopefully we can get faster to the discovery of the causes of this evil and soon we will find the best way to treat dogs and humans.”

The project, developed by the Translational Genomics Research Institutes (TGen) and Van Andel Research (VARI), will have the cooperation of owners of various breeds of dogs, they will donate samples of saliva from your pets, and even tumors blood, to be examined.

A new study at the Institute of Cellular Physiology, UNAM (Mexico) on the initiation and progression of cancer, which can be found in the ‘envelope’ of DNA in a structure called chromatin.

After seven years of research it was discovered that DNA is not naked inside the nucleus of cells, is involved in chromatin, a structure whose function is as a link that contains genetic information. If the league is compact and focused, you can not read the DNA, but if you relax and stretch it can be read.
The scientist Felix Recillas Targa and his team found that changes in chromatin structure resulting in not express proteins that regulate the activation of two tumor suppressor genes in humans, called p53 and Retinoblastoma.

Not suppressor genes turned on, it opens the way to cancer, although there is no genetic mutation, explained.

The prognosis of primary peritoneal cancer is one of the things that do not just want to feel less alone with approx. But mostly, you know someone or heard of anyone that this devastating disease.

Women with low vitamin D levels had a 94 percent chance the cancer would spread through the body, ten years after diagnosis
Vitamin D levels and mortality of breast cancers among women are directly related, according to a Canadian study released by the American Society of Clinical Oncology.

According to the study, women diagnosed with breast cancer and low vitamin D levels have twice the chance of disease spreading through his body and 73 percent more likely to die from cancer than women with high amounts of the vitamin.

In the more northern countries of the world-including Canada-a lack of vitamin D is endemic due to the few hours of sunshine during the long winters. The lack of sunlight prevents the body naturally produces vitamin through contact of skin with ultraviolet rays.
