Scientists test device to track medication adherence in patients with HIV/AIDS |
|
Monday, 21 April 2008 |
Most of us have missed a dose of antibiotic or forgotten to take a
daily vitamin. But when the stakes are higher — as they are for people
with HIV/AIDS — a skipped pill could mean the difference between health
and hazard for the entire population.
Now, a breath monitoring
device developed by scientists at the University of Florida and Xhale
Inc. could help prevent the emergence of drug-resistant strains of HIV
by monitoring medication adherence in high-risk individuals.

As If Having a Tumor Isn't Enough... |
|
Monday, 21 April 2008 |
|
New research has shown that the function of a type of cell that
helps modulate immune responses is impaired inside tumors in mice.
Researchers also identified several factors that may contribute
to an accumulation of these cells, called T regulatory cells (Tregs),
within and around the tumor, which may be how they respond to their
loss of functionality. The study, by scientists at the National
Cancer Institute (NCI), part of the National Institutes of Health,
appeared online April 18, 2008, in The Journal of Immunology.

Stem Cells And Cancer: Scientists Investigate A Fine Balancing Act |
|
Monday, 14 April 2008 |
|
Speaking at the UK National Stem Cell Network Annual Science Meeting in
Edinburgh, on April 11, Professor Silvia Marino shows how the
mechanisms normally involved in balancing different functions of stem
cells may also contribute to cancer. Her team from Barts and the London
School of Medicine and Dentistry is currently delving into these
mechanisms to understand how stem cells are normally regulated and what
role they may play in malignant brain tumours.

Gene Linked to Inherited Blood Biomarker Associated with Asthma Risk |
|
Monday, 14 April 2008 |
|
Risk for developing asthma is linked to variants in a gene called
CHI3L1, which can be measured by checking levels of an inherited
blood protein regulated by that gene, according to new research
sponsored by the National Heart, Lung, and Blood Institute (NHLBI)
of the National Institutes of Health. Researchers identified gene variants which are associated with
increased susceptibility to asthma and reduced lung function in
three study populations. The variants regulate the level of a blood
protein called YKL-40, which, through previous NHLBI-funded research,
has been shown to be elevated in people with asthma and correlate
with asthma severity. This new research shows that the YLKL-40
protein is inherited, and can be measured from birth.
