Stem Cell :: Effects of aging in stem cells
In highly purified hematopoietic stem cells from mice aged 2 to 21 months, gene expression analysis indicates a deficit in function, yet an increase in stem cell number with advancing age.
Evidence
Heart :: Use of pulmonary artery catheter decreases substantially in US
Use of the pulmonary artery catheter decreased by 65 percent in the US between 1993 and 2004, possibly due to growing evidence that this invasive procedure does not reduce the risk of death for hospitalized patients, according to a study in the July 25 issue of JAMA.
Healthcare :: Health reform bills could improve quality and efficiency, but fall short of national plan
Several health reform bills before Congress could lead to significant improvements in health care quality and efficiency, but they fall short of an overarching, coordinated plan that would create a better overall health care system for the country, according to an analysis released today by the Commonwealth Fund and prepared for the Commonwealth Fund Commission on a High Performance Health System.
Cancer :: Many Americans believe unsubstantiated claims about cancer
A new study from American Cancer Society researchers finds a surprising number of Americans believe scientifically unsubstantiated claims concerning cancer, and that population segments suffering the greatest burden of cancer are the most likely to be misinformed.
Diabetes :: Top-10 comparison of diabetes drugs give metformin top grade
A type 2 diabetes drug taken orally and in widespread use for more than a decade has been found to have distinct advantages over nine other, mostly newer medications used to control the chronic disease, according to a study by researchers at Johns Hopkins.
Influenza :: Detecting transmissibility of avian influenza virus in human households
Recent outbreaks of emerging diseases such as SARS and H5N1 avian influenza have underlined the fact that animal pathogens may acquire the ability to spread efficiently in humans ? but as yet have not. Monitoring the transmissibility of pathogens from animals in humans is therefore key for early detection of epidemic spread, and for effective control.
Gene :: Call for EU to launch major project to map out all our proteins
Biologists still have no clear idea how many active genes there are coding for proteins in humans and other organisms, even though for some species the genomes have been completely sequenced.
Gene :: Gene for itch sensation discovered
Itching for a better anti-itch remedy” Your wish may soon be granted now that scientists at Washington University School of Medicine in St. Louis have identified the first gene for the itch sensation in the central nervous system.
HIV :: Treating HIV infected infants early helps them live longer
Hundreds of thousands of babies around the world are born each year with HIV–more than half a million in 2006 alone. Caring for these children is complicated by the fact that their immune systems are not fully developed in the first year of life, which makes them especially susceptible to rapid HIV disease progression and death.
Pregnancy :: Prenatal alcohol exposure alters brain activity in the frontal-striatal areas
Heavy prenatal alcohol exposure does not always lead to fetal alcohol syndrome (FAS); sometimes it can lead to cognitive and behavioral deficits in the absence of craniofacial features needed to make an FAS diagnosis.
