Early cognitive problems documented among those who eventually get Alzheimer's Posted: 28 Dec 2012 10:07 AM PST People who study or treat Alzheimer's disease and its earliest clinical stage, mild cognitive impairment (MCI), have focused attention on the obvious short-term memory problems. But a new study suggests that people on the road to Alzheimer's may actually have problems early on in processing semantic or knowledge-based information, which could have much broader implications for how patients function in their lives.

56% of female university students get drunk in record time, Spanish study suggests Posted: 28 Dec 2012 05:40 AM PST Researchers have studied university students' lifestyles; their analysis, which includes alcohol and illegal drug consumption habits, sport and food, concludes that most students indulge in unhealthy behavior. One of the main results of the study points to the high consumption of alcohol.

Trying to halt hepatitis C's molecular hijacking Posted: 27 Dec 2012 02:33 PM PST Researchers have figured out intimate details of how the hepatitis C virus takes over an invaded cell, a breakthrough that could point to way for new treatments for the virus.

Staphylococcus aureus: Why it just gets up your nose Posted: 27 Dec 2012 02:33 PM PST Researchers have identified a mechanism by which the bacterium Staphylococcus aureus colonizes our nasal passages. The study shows for the first time that a protein located on the bacterial surface called clumping factor B has high affinity for the skin protein loricrin.

The factor that could determine future breast cancer treatment Posted: 27 Dec 2012 02:33 PM PST Australian scientists have shown how a 'transcription factor' causes breast cancer to develop an aggressive subtype that lacks sensitivity to oestrogen and does not respond to anti-oestrogen therapies such as Tamoxifen and aromatase inhibitors. Transcription factors are molecules that switch genes on or off. In this case, the transcription factor known as 'ELF5' inhibits sensitivity to oestrogen very early in the life of a breast cancer cell.

Scientists home in on cause of osteoarthritis pain Posted: 27 Dec 2012 02:30 PM PST Researchers have identified a molecular mechanism central to the development of osteoarthritis (OA) pain, a finding that could have major implications for future treatment of this often-debilitating condition.

Cholesterol drug shows promise in fighting effects of malaria Posted: 27 Dec 2012 02:30 PM PST Researchers have discovered that adding lovastatin, a widely used cholesterol-lowering drug, to traditional antimalarial treatment decreases neuroinflammation and protects against cognitive impairment in a mouse model of cerebral malaria.
