| Scientists discover mutations associated with skin disorder (DSAP) Posted: 16 Sep 2012 01:09 PM PDT Scientists have found strong genetic evidence of a link between mutations of the mevalonate kinase gene (MVK) and disseminated superficial actinic porokeratosis (DSAP). It is a major step toward discovering the genetic pathogenesis of DSAP, and sheds light on its further molecular diagnosis and treatment.  |
| Flu antibody’s 'one-handed grab' may boost effort toward universal vaccine, new therapies Posted: 16 Sep 2012 01:08 PM PDT Scientists have solved the co-crystal structure of a human antibody that can neutralize influenza viruses in a unique way. The antibody recognizes the crucial structure that flu viruses use to attach to host cells, even though previously this structure had been thought too small for an antibody to grab effectively. The immune protein manages to hit this precise spot by using just a small part of its target-grabbing apparatus. In so doing, it can neutralize a broad range of dangerous flu viruses.  |
| Breath analysis could help diagnose pulmonary nodules, study shows Posted: 16 Sep 2012 08:44 AM PDT A pilot study showed that breath testing could be used to discriminate between benign and malignant pulmonary nodules. The study looked at 74 patients who were under investigation for pulmonary nodules and attended a referral clinic in Colorado between March 2009 and May 2010.  |
| Abstinence from alcohol plus physical exercise can help reclaim bone loss due to alcoholism Posted: 14 Sep 2012 04:16 PM PDT Alcoholism is known to cause osteoporosis, or reduced bone mineral density (BMD). New findings indicate that as little as eight weeks of abstinence can initiate correction of an imbalance between bone formation and resorption due to alcohol's toxic effects. Physical activity can also serve as a protective factor against reduced BMD.  |
| Maternal drinking during pregnancy can damage the earliest fetal learning Posted: 14 Sep 2012 04:16 PM PDT Habituation refers to the ability of an organism to stop responding to repeated stimulation. A new study has examined the impact of maternal drinking on fetal habituation or learning abilities while still residing in the mother's womb. Results showed that those fetuses exposed to heavy binge drinking required significantly more trials to habituate, and also exhibited a greater variability in test performance.  |
