Brain images reveal effects of antidepressants

Researchers used functional magnetic resonance imaging (fMRI) to study the effects of antidepressant venlafaxine on clinically depressed patients. The study found that the drug produced robust alterations in the anterior cingulate area of the brain within two weeks, which may help predict treatment response.

Neurofibromin: It's so degrading

The discovery of neurofibromin regulation may help develop targeted therapies to block neurofibromin degradation in NF1 patients and treat cancers with amplified Ras activity. Nf1 heterozygous cells show increased sensitivity to growth factors, suggesting even diminished neurofibromin levels can affect normal cell behavior.

US researchers find first conclusive evidence that lead is linked to male infertility

A study by US researchers found a significant association between high lead levels in seminal plasma and low fertilization rates. Lead was shown to interfere with sperm function, including binding to the egg and penetrating its coating. The findings suggest that lead may be a contributory factor of declining sperm counts.
