Calcium May be the Key to Understanding Alzheimer's Disease |
|
Monday, 21 July 2008 |
|
Researchers at the University of Pennsylvania School
of Medicine have shown that mutations in two proteins associated with
familial Alzheimer's disease disrupt the flow of calcium ions within
neurons. The two proteins, called PS1 and PS2 (presenilin 1 and 2),
interact with a calcium release channel in an intracellular cell
compartment.

|

organisation (NGO) providing HIV and Aids education and support, among
men who have sex with men (MSM) the proportion who contracted HIV had
shot up by 67 percent between 2006 and 2007.

Using the Net to Track Infectious Disease |
|
Tuesday, 08 July 2008 |
|
Could Internet discussion forums, listservs, and online news outlets
be an informative source of information on disease outbreaks? A team of
researchers from Children's Hospital Boston and Harvard Medical School
thinks so, and it has launched a real-time, automated data-gathering
system called HealthMap to gather, organize and disseminate this online
intelligence. They describe their project in this week's PLoS Medicine.

New antibiotic beats superbugs at their own game |
|
Thursday, 03 July 2008 |
|
The problem with antibiotics is that, eventually, bacteria outsmart
them and become resistant. But by targeting the gene that confers such
resistance, a new drug may be able to finally outwit them. Rockefeller
University scientists tested the new drug, called Ceftobiprole, against
some of the deadliest strains of multidrug-resistant Staphylococcus
aureus (MRSA) bacteria, which are responsible for the great majority of
staphylococcal infections worldwide, both in hospitals and in the
community.
