Stem cell research can continue to get federal funding, appeals court rules
Los Angeles Times    Share    Share on FacebookTwitterShare on LinkedinE-mail
A U.S. appeals court cleared the way for continued federal funding of research using human embryonic stem cells, a ruling that scientists hailed as a victory for medical progress. Stem cells from embryos are believed to hold great promise for treating hard-to-treat illnesses or conditions, such as Parkinson's disease or spinal cord injuries. But the research itself remains controversial because it makes use of cells from early-stage embryos. More

Medscape    Share    Share on FacebookTwitterShare on LinkedinE-mail article
HIV infection is a risk factor for heart failure, with ongoing viral replication associated with higher risk, according to the results of a population-based, retrospective study reported in the Archives of Internal Medicine.

Amyloid beta 1-42 linked to outcome after cardiac arrest
Medscape    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A new study using a sensitive assay technology shows a time-dependent rise in amyloid beta 1-42 (Aβ-42) in the blood of patients resuscitated after cardiac arrest. A strong correlation was seen between the rise and fall of Aβ-42 in the hours after arrest and clinical outcomes, suggesting the elevated Aβ-42 level is derived from the brain of these patients. It also suggests this might be used as a marker of damage in the same way that troponins reflect cardiac damage after myocardial infarction. More
