Structured Weight Loss Program Helps Kids from Low-Income Families Lower BMI

Posted: 13 Mar 2013 09:16 AM PDT

Overweight and obese children in low-income households can meet or exceed the Expert Committee Recommendations Regarding the Prevention, Assessment, and Treatment of Childhood and Adolescent Overweight and Obesity when given access to a structured weight management program, according to a new study published in Academic Pediatrics.

Neuron Loss in Schizophrenia and Depression Could Be Prevented With an Antioxidant

Posted: 13 Mar 2013 09:12 AM PDT

Gamma-aminobutyric acid (GABA) deficits have been implicated in schizophrenia and depression. In schizophrenia, deficits have been particularly well-described for a subtype of GABA neuron, the parvalbumin fast-spiking interneurons. The activity of these neurons is critical for proper cognitive and emotional functioning.

New Technique Creates Stronger, Lightweight Magnesium Alloys

Researchers from North Carolina State University have developed a new technique for creating stronger, lightweight magnesium alloys that have potential structural applications in the automobile and aerospace industries.

Polycystic ovary syndrome puts glucose control in double jeopardy

Posted: 13 Mar 2013 08:24 AM PDT

Polycystic ovary syndrome, a condition affecting about 10 percent of women and characterized by excess male hormone and increased risk of diabetes and heart disease, appears to cause a sort of double jeopardy for those struggling the hardest to control blood sugar levels, researchers report.

Humans use insulin and other non-insulin mechanisms to convert blood sugar, or glucose, into energy and control levels in the blood, where it becomes a destructive force.

Extreme water

Earth is the only known planet that holds water in massive quantities and in all three phase states. But the earthly, omnipresent compound water has very unusual properties that become particularly evident when subjected to high pressure and high temperatures. In the latest issue of the Proceedings of the National Academy of Sciences (PNAS), a German-Finnish-French team published what happens when water is subjected to pressure and temperature conditions such as those found in the deep Earth.

Using Fat to Fight Brain Cancer

In laboratory studies, Johns Hopkins researchers say they have found that stem cells from a patient’s own fat may have the potential to deliver new treatments directly into the brain after the surgical removal of a glioblastoma, the most common and aggressive form of brain tumor.
