Experiments on mouse models of Alzheimer’s disease suggest that treatment with male sex hormones might slow its progression. The findings, published in the Dec. 20 issue of the Journal of Neuroscience, provide new insight into the relationship between testosterone loss and AD, which affects 4.5 million Americans.
Researchers at the University of Maryland School of Medicine in Baltimore will begin a clinical trial in January to test the first cell culture-based pandemic influenza vaccine to see if it will provide immunity faster and more reliably than a vaccine produced in eggs. The new study is also the first test in the United States of a whole virus vaccine for avian influenza, which could produce a stronger response by the immune system.

How would distribution of wealth change if the United States were to enter a period of inflation?

Whether reopening narrowed kidney arteries benefits patients is a $1.7 billion question a North American study hopes to answer.
Viewing prior mammograms in association with current mammograms significantly improves radiologist performance and may decrease unnecessary recalls by up to 44 percent, according to a study in the January issue of Radiology.
Right now there’s no rapid way to diagnose sepsis, a fast-moving blood infection that is a leading cause of death in hospital intensive care units. New research at Washington University School of Medicine in St. Louis suggests that doctors one day could quickly distinguish sepsis from widespread non-infectious inflammation based on genetic profiles of patients’ blood.
Three more cases of a new strain of MRSA have been identified at the University Hospital of North Staffordshire where two people have already died from the “superbug” – Methicillin-resistant Staphylococcus aureus (MRSA).
People with low levels of LDL cholesterol are more likely to have Parkinson’s disease than people with high LDL levels, according to University of North Carolina at Chapel Hill researchers.
