| Attacking MRSA with metals from antibacterial clays Posted: 18 May 2013 12:37 PM PDT Medical researchers have come up with a new approach for developing effective, topical antibacterial agents -- one that draws on a naturally occurring substance recognized since antiquity for its medicinal properties: clay.  |
| Now we know why old scizophrenia medicine works on antibiotics-resistant bacteria Posted: 18 May 2013 12:37 PM PDT An old medicine for schizophrenia is effective at treating something completely different than it was designed for: antibiotic-resistant bacteria. So far it has been a mystery how this old schizophrenia medicine works, but now researchers have figured it out. This can lead to a new medicine against the increasingly threatening antibiotic-resistant bacteria.  |
| Youth who have their first drink during puberty have higher levels of later drinking Posted: 18 May 2013 12:37 PM PDT The earlier the age at which youth take their first alcoholic drink, the greater the risk of later alcohol problems.  |
| College women exceed NIAAA drinking guidelines more frequently than college men Posted: 18 May 2013 12:37 PM PDT In 1990, the National Institute on Alcohol Abuse and Alcoholism issued guidelines that define low-risk drinking, which differ for men and women. New research shows that female college student drinkers exceed NIAAA guidelines for weekly drinking more frequently than their male counterparts.  |
| Individuals who drink heavily and smoke may show 'early aging' of the brain Posted: 18 May 2013 12:34 PM PDT Alcohol treatment interventions work best when patients understand and are actively involved in the process. A first-of-its-kind study looks at the interactive effects of smoking status and age on neurocognition in one-month-abstinent alcohol dependent (AD) individuals in treatment. Results show that AD individuals who currently smoke have more problems with memory, ability to think quickly and efficiently, and problem-solving skills than those who do not smoke, effects which seem to become greater with increasing age.  |
| Posted: 18 May 2013 12:32 PM PDT Chronic trauma can inflict lasting damage to brain regions associated with fear and anxiety. Previous imaging studies of people with post-traumatic stress disorder, or PTSD, have shown that these brain regions can over-or under-react in response to stressful tasks.  |
| Ketamine shows significant therapeutic benefit in people with treatment-resistant depression Posted: 18 May 2013 12:32 PM PDT Drug associated with rapid antidepressant effect in largest clinical trial to-date.  |
| Women's reproductive ability may be related to immune system status Posted: 17 May 2013 12:24 PM PDT Anthropologists have showed that a woman's reproductive function may be tied to her immune system's status.  |
