University of Alberta obesity expert Dr. Arya Sharma, along with a researcher from Northwestern University in Chicago, Illinois, has proposed a classification system to help doctors assess and treat overweight patients. http://www.physorg.com/news153499978.html Medicine & Health Tue, 10 Feb 2009 14:53:38 EST news153499978 A new study in Psychological Science reveals that nonverbal cues can give away a person's socioeconomic status (SES). Volunteers whose parents were from upper SES backgrounds displayed more disengagement-related behaviors compared to participants from lower SES backgrounds. In addition, when a separate group of observers were shown 60 second clips of the videos, they were able to correctly guess the participants' SES background, based on their body language. http://www.physorg.com/news152973534.html Medicine & Health Wed, 04 Feb 2009 12:39:16 EST news152973534 A component of DNA that can both stimulate and suppress the immune system, depending on the dosage, may hold hope for treating cancer and infection, Medical College of Georgia researchers say. http://www.physorg.com/news152285494.html Medicine & Health Tue, 27 Jan 2009 13:32:07 EST news152285494 At Hogwarts, Harry Potter uses an invisibility cloak to hide from his enemies.

In the January issue of Cell Metabolism, Massachusetts General Hospital (MGH) investigators outline a system in which there may be several steady states to which an animal's weight tends to gravitate, rather than a single "set point." http://www.physorg.com/news151158880.html Other Sciences Wed, 14 Jan 2009 12:34:40 EST news151158880 New research published in the January issue of the Journal of the American College of Surgeons shows that morbidly obese patients are at higher risk than normal weight patients for complications after colectomy - surgical removal of all or part of the colon - for the treatment of cancer. http://www.physorg.com/news151152642.html Medicine & Health Wed, 14 Jan 2009 10:50:42 EST news151152642 A new randomized, prospective trial has shown that orlistat, a commonly prescribed inhibitor of fat absorption, does not help patients with fatty liver disease (FLD) lose weight, nor does it improve their liver enzymes or insulin resistance.

She said, "Compared to normal weight women who accurately assessed their pre-pregnancy weight status, the odds of gaining excessively during pregnancy were increased seven-fold among overweight and obese women who thought they weighed less than they really did. Normal weight women who thought they were overweight had twice the odds of excessive gestational weight gain." http://www.physorg.com/news149169633.html Medicine & Health Mon, 22 Dec 2008 12:00:33 EST news149169633 (PhysOrg.com) -- In 1980, when America was still dealing with the oil crisis from the previous decade, Ann Kolanowski, Elouise Ross Eberly Professor of Nursing at Penn State and director of the John A.
