Oxytocin Level and Mother-Child BondHumans are hard-wired to form enduring bonds with others. One of the primary bonds across the mammalian species is the mother-infant bond. Evolutionarily speaking, it is in a mother's best interest to foster the well-being of her child; however, some mothers just seem a bit more maternal than others do. Now, new research points to a hormone that predicts the level of bonding between mother and child.
In animals, oxytocin, dubbed "the hormone........Go to the Psychology news blog (Added on 10/15/2007 9:52:07 PM)
Night-time acid reflux can impact sleepAs per results of a survey presented at the 72nd Annual Scientific Meeting of the American College of Gastroenterology, nighttime acid reflux, along with some of the less typical manifestations or symptoms of gastroesophageal reflux disease (GERD), is linked to significant sleep impairment.
In a recent national survey, scientists assessed the prevalence of sleep impairment among people with GERD and people without GERD based on response to........Go to the GI news blog (Added on 10/15/2007 6:09:18 PM)
Serious, manifestations of acid refluxA number of people may not realize that symptoms such as chronic cough or chest pain can be caused by acid reflux into the esophagus, because they do not experience classic heartburn symptoms or acid regurgitation. Two new studies presented at the 72nd ACG Annual Scientific Meeting highlight the little known correlation between gastroesophageal reflux and seemingly unrelated problems.

Why some prostate cancer recurs after treatmentCancer scientists have long worked to understand why some prostate cancers recur after the use of therapies designed to stop the production of testosterone and other androgens that fuel cancer cell growth. New research has now detected that androgen-synthesizing proteins are present within cancer cells, which suggests that cancer cells may develop the capacity to produce their own androgens.
The presence of these proteins may explain why........Go to the Prostate-cancer-blog (Added on 10/11/2007 10:29:44 PM)
