Atkins Diet Controls Weight and Stress
Written by WTJ on October 20, 2009 – 6:32 am -
Scientists from University of South Florida and Tampa VA Hospital found that Atkins diet helps in weight control and stress management better than American diet on rats. Atkins-type diet is a diet high in animal and vegetable fat with low level of sugar. American-type diet is high in both fat and sugar. The scientists found that rats fed with low carb diet (Atkins diet) exhibited lower fear memories in response to a scary experience.
Professor David Diamond, in the Departments of Psychology, Molecular Pharmacology and Physiology, University of South Florida, presented the findings at the Annual Society for Neuroscience conference in Chicago on Oct 17.

Protein Links to Stress and Depression
Written by WTJ on March 1, 2009 – 10:47 am -
Recent studies showed that a protein called kainate receptors response to certain antidepressants, and the protein also involved in depression and suicidal thought.
Scientists at Rockefeller University examined one of the five subunits of kainate receptors, KA1 in rats and the result may help to explain the mechanism of the protein reshaping the brain in response to stress. Researchers at Harold and Margaret Milliken Hatch Laboratory of Neuroendocrinology at Rockefeller University studied the impact of stress and steroid on rats. They induce stress to the rats by restraining them 6 hours per day for over three weeks. The production of KA1 in these rats increased in certain parts of hippocampus under the instruction sent by messenger RNA. Hippocampus involved in learning and memory functions. Scientists also tried to inject hormone called corticosteroids into the unstressed rats. Low dose of corticosteroids increased KA1 production but high dose did not.
Fortunately the brains will replace the retracted neurons once the stress is removed. The study was published in the journal PLos ONE. The authors were Richard G. Hunter, Rudy Bellani, Erik Bloss, Ana Costa, Katharine McCarthy, and Bruce S. McEwen.

Stressed Parents Smack Kids
Written by WTJ on December 19, 2007 – 10:17 am -New Zealand’s kids will hate you if you stressed their parents:
“We found that young parents are less likely to smack or use more severe physical punishment methods if they are caring for fewer children, have low levels of financial and relationship stress, and have had positive parenting role models on which to base their own.”
This research was published in New Zealand Medical Journal. Asian kids always got bitten by their parents, I guess they’re just stressed out.
Russell Peters urged white parents hit their kids, or else they’ll be discriminated by other races in school as every kids got smacked by their parents. Guess what my parents told my school teachers when I was in elementary school? “If you found that he’s naughty, just hit him, the harder the better.”
Rotan (in malay) a.k.a. rattan was the weapon that my parents use to smack me. The thinner it is, the more painful you would feel. This rotan thing is amazing. It very flexible, no matter how much you bend it, it won’t break into half. It’s not bamboo as it’s not hollow inside.
