Mushrooms are good source of vitamin D

The Institute of Medicine (IOM) recently released the results of its 24-month review on dietary reference intakes (DRIs) for vitamin D and calcium, which validated the importance of vitamin D as an essential nutrient for promoting bone health. The committee set the recommended intake level at 600 IU, which is triple the previously recommended amount from 1997.

Research on ribosome could aid antibiotic development against MRSA infection

Theoretical biologists at Los Alamos National Laboratory have used a New Mexico supercomputer to aid an international research team in untangling another mystery related to ribosomes-those enigmatic jumbles of molecules that are the protein factories of living cells.

Scientists propose new effort to identify proteins in cancer cells

Scientists are proposing an international effort, on the scale of the Human Genome Project (HGP), to identify all the proteins present in cancer cells. HGP was the international scientific research project that identified and mapped all the genes in humans.

Study of proteins under jam-packed conditions may open new treatment for diseases

People in a jetliner act and feel one way when crammed together like sardines in a can. But they have quite a different mindset when the middle seat is empty and they have more personal space. Scientists are pursuing a remarkable parallel that exists among the proteins involved in health and disease inside living cells.

Quitting smoking eases symptoms of depression

Quitting smoking is certainly healthy for the body, but doctors and scientists haven't been sure whether quitting makes people happier, especially since conventional wisdom says many smokers use cigarettes to ease anxiety and depression. In a new study, researchers tracked the symptoms of depression in people who were trying to quit and found that they were never happier than when they were being successful, for however long that was.

New approach to biomarker detection for early lung cancer diagnosis

Even with astounding advances in genomic science, genetic analysis of disease remains largely a measure of risk rather than actual disease state. A truer and more immediate measure of health can be obtained by analysis of proteins, especially those that are biomarkers of disease state.

Trillium presents results from cancer stem cell program at ASH Annual Meeting

Trillium Therapeutics Inc. (TTI), a biopharmaceutical company developing innovative immune-based biologics, today announced that preliminary results from its cancer stem cell program, targeting the CD47 protein, will be reported in an oral presentation at the 52nd American Society of Hematology (ASH) Annual Meeting to be held in Orlando, Florida, December 4-7, 2010.

MicroRNA linked to mosquito blood digestion and egg development identified

Each year, dengue fever infects as many as 100 million people while yellow fever is responsible for about 30,000 deaths worldwide. Both diseases are spread by infected female Aedes aegypti mosquitoes, which require vertebrate blood to produce eggs. The blood feeding and the egg development are tightly linked to how the mosquito transmits the disease-causing virus.

Study on animal model may impact treatment of stroke

The results of two studies published in the current issue of Cell Transplantation (19:9) using animal models of cerebral ischemia and ischemic stroke in rats may significantly impact the treatment of stroke in humans.

Emotional, social self-efficacy beliefs may contribute on strengthening major expressions of positive orientation

This study demonstrates that emotional and social self-efficacy beliefs may contribute on strengthening major expressions of positive orientation. The more people draw, from experience, their beliefs to be able to properly handle their emotions and their relations with others, the more they can preserve and enhance a positive evaluation of self, life and the future.

AVMA condemns actions of animal rights activists against UCLA research neuroscientist

Citing its policy on the use of animals in research, testing and education, the American Veterinary Medical Association (AVMA) today condemned the recent actions of animal rights activists who have targeted a University of California research neuroscientist. The scientist's work includes the use of nonhuman primates to research biochemical factors that contribute to methamphetamine and tobacco addiction in adolescents, as well as to better understand cognitive problems that contribute to behavioral, speech and reasoning disabilities in schizophrenics.

IOF commends IOM's new vitamin D and calcium intake recommendations

On November 30, 2010, the Institute of Medicine of the National Academy of Sciences (IOM) in the US released new recommendations on daily reference intakes for vitamin D and calcium across all ages. The report is based on available evidence in the literature, with higher quality studies, supporting the role of these nutrients on bone health. Vitamin D deficiency is an important health issue to address as it has been linked to the pathogenesis of osteoporosis and hip fractures as well as other skeletal and non-skeletal disorders.

Impairments to health and physical performance are due to unfavorable lifestyle habits and lack of exercise

Impairments to health and physical performance are not primarily a result of aging but of unfavorable lifestyle habits and lack of exercise. This is the position taken by Dieter Leyk and his coauthors in the new issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2010; 107[46]: 809-16).

Scientists find new protein to break-up blood clots in prion diseases

The joy of a juicy hamburger could make a comeback thanks a new discovery by scientists from the University of Kentucky. In a new research report in the December 2010 print issue of The FASEB Journal, scientists found that a protein our body uses to break up blood clots speeds up the progress of prion diseases. This substance, called plasminogen, is a new drug target for prion diseases in both humans and animals.
