Link found between vitamin D insufficiency and asthma severity

Serum levels of vitamin D in more than 600 Costa Rican children were inversely linked to several indicators of allergy and asthma severity, including hospitalizations for asthma, use of inhaled steroids and total IgE levels, according to a study that will appear in the first issue for May of the American Journal of Respiratory and Critical Care Medicine.

Lymphocytes promote cancer spread

Researchers at the UC San Diego School of Medicine and the Moores UCSD Cancer Center have new evidence that a type of immune system cell thought to be part of the first line of defense against breast cancer may also help promote its spread.

First human study of pioneering 'cell bandage' technology

A company co-founded by Professor Anthony Hollander has raised over £1.6 million to fund trials, including the first human study, of its pioneering 'cell bandage' technology, which aims to save thousands of patients from the type of knee surgery that currently leads to premature osteoarthritis.

Cells from human blood can morph into stem cells

In a recent study, U.S. researchers have reprogrammed cells found in circulating blood into cells that are molecularly and functionally indistinguishable from embryonic stem cells, a revolutionary achievement that provides a readily accessible source of stem cells and an alternative to harvesting embryonic stem cells.

Discovery of gene that protects against leukemia

Researchers have identified a gene that controls the rapid production and differentiation of the stem cells that produce all blood cell types -- a discovery that could eventually open the door to more streamlined treatments for leukemia and other blood cancers, in which blood cells proliferate out of control.
