Clues about how blood forms could yield new strategies for treating blood diseases

Biologists have long wondered why the embryonic heart begins beating so early, before the tissues actually need to be infused with blood.

New mathematical model predicts immune response to influenza A virus

Researchers at the University of Rochester have developed a mathematical model to predict immune responses to infection with influenza A viruses, including novel viruses such as the emergent 2009 influenza A (H1N1). This model examines the contributions of specific sets of immune cells in fighting influenza A virus.

Banned toxic chemicals in Australian everyday products

Australia's leading consumer advocacy organisation CHOICE says an investigation has revealed that many chemicals freely available in Australia are no longer registered in Europe because of safety concerns.

Meditation may increase gray matter

Push-ups, crunches, gyms, personal trainers - people have many strategies for building bigger muscles and stronger bones. But what can one do to build a bigger brain?

DHEA supplement combined with vitamin D and calcium significantly improves spinal bone density in older women

"The results of our study are very promising. Similar studies have demonstrated much smaller benefits for bone than we found. However, calcium and vitamin D deficiencies, which are present in half of older adults, may have prevented DHEA from improving bone density in the earlier studies," said Edward Weiss, Ph.D., associate professor of nutrition and dietetics at Saint Louis University's Doisy College of Health Sciences and lead author of the study.

Researchers screen the smallpox proteome

University of Florida researchers have learned more about how smallpox conducts its deadly business - discoveries that may reveal as much about the human immune system as they do about one of the world's most feared pathogens.

New genetic clues to treatment of hypertension

An international research team has identified a number of unsuspected genetic variants associated with systolic blood pressure (SBP), diastolic blood pressure (DBP), and hypertension (high blood pressure), suggesting potential avenues of investigation for the prevention or treatment of hypertension.

Closer to an effective treatment for gum disease in smokers

Scientists in the USA have discovered why smokers may be more prone to chronic gum disease (periodontitis). One of the bacteria responsible for this infection responds to cigarette smoke - changing its properties and the way it infects a smokers mouth.

Discovery of major new treatment target in diseased arteries

Removing a single protein prevents early damage in blood vessels from triggering a later-stage, frequently lethal complication of atherosclerosis, according to research published online today in the journal Nature Medicine. By eliminating the gene for a signaling protein called cyclophilin A (CypA) from a strain of mice, researchers were able to provide complete protection against abdominal aortic aneurysm (AAA).

Africa prepares for possible H1N1 flu outbreak amid concerns about HIV/AIDS, other diseases

African countries are preparing for the possibility that the H1N1 flu virus could expand in the continent, which already is experiencing epidemics of diseases such as HIV/AIDS and malaria, the AP/San Francisco Chronicle reports.

Study reveals current multi-component vaccines may need reworking

Current strategies for designing vaccines against HIV and cancers, for instance, may enable some components in multi-component vaccines to cancel the effect of others on the immune system, eliminating their ability to provide protection, according to an article to be published shortly in the Proceedings of the National Academy of Sciences (PNAS).

Wistar Institute obtains U.S. patent for a novel synthetic vaccine technology

The Wistar Institute today obtained a U.S. patent for a novel synthetic vaccine technology with the potential for further development into a universal flu vaccine which could eliminate the need for annual flu shots and protect against future flu pandemics.

A vaccine for swine flu will depend on what happens next

The World Health Organisation (WHO) says as of the 5th of May 2009, 21 countries have now officially reported 1,490 cases of influenza A (H1N1) infection (swine flu).

Mushrooms may boost the body's natural immune system

The potential for mushrooms to fight influenza is being examined following United States research suggesting the body's natural immune response against viral infections and tumours is boosted through the consumption of white button mushrooms.

Scientists coax skin cells to behave like muscle cells and vice versa

Even cells aren't immune to peer pressure. Scientists at the Stanford University School of Medicine have now shown that skin cells can be coaxed to behave like muscle cells - and muscle cells like skin cells - solely by altering who they hang out with: the relative levels of the ingredients inside the cell.
