How Red Wine's Resveratrol Confers Health Benefits
Scientists have found out why resveratrol, a chemical naturally found in red wine, grapes, and some other fruit and vegetables, has health benefits, according to an article published in the journal Cell, February 3rd issue...

Pneumonia Survival May Improve With Stimulation Of Brain Hormone Action
An international research team may have found a way to block a second wave of death that can result from pneumonia treatment. Antibiotics are effective at killing pneumococcus - the cause of about 50 percent of pneumonias - but as it dies the bacterium releases potentially lethal toxins...

Study Finds Testosterone Makes Us Less Cooperative And More Egocentric
Testosterone makes us overvalue our own opinions at the expense of cooperation, research from the Wellcome Trust Centre for Neuroimaging at UCL (University College London) has found. The findings may have implications for how group decisions are affected by dominant individuals...

Sugar - Attacking Health Globally
A recent study published in Nature by Robert Lustig, MD, Laura Schmidt, PhD, MSW, MPH, and Claire Brindis, DPH, and colleges at the University of California, San Francisco, reveals that sugar is as dangerous when over-consumed as tobacco or alcohol, and should be used in moderation...

What Is Brown Fat? What Is Brown Adipose Tissue?
Brown adipose tissue (BAT), also known as brown fat, is one of two types of fat humans and other mammals have - the other type is known as white or yellow fat. Human newborns and hibernating mammals have high levels of brown fat. Brown fat's main function is to generate body heat...

Caffeine Consumption Linked To Estrogen Changes
Asian women who consumed an average of 200 milligrams or more of caffeine a day - the equivalent of roughly two cups of coffee - had elevated estrogen levels when compared to women who consumed less, according to a study of reproductive age women by researchers at the National Institutes of Health and other institutions...

Caffeine Alters Estrogen Levels
Researchers at the National Institute of Health, along with other institutions, have released a study online in the American Journal of Clinical Nutrition, stating that Asian women have higher estrogen levels when drinking 200 milligrams or more of caffeine a day. This is about 2 cups of coffee...

Appetite Accomplice: Ghrelin Receptor Alters Dopamine Signaling
New research reveals a fascinating and unexpected molecular partnership within the brain neurons that regulate appetite. The study, published by Cell Press in the January 26 issue of the journal Neuron, resolves a paradox regarding a receptor without its hormone and may lead to more specific therapeutic interventions for obesity and disorders of dopamine signaling...

Brown Fat - Keeps You Warm And Keeps You Slim
People with more brown fat seem better able to stay warm when it is cold, Canadian researchers reported in the Journal of Clinical Investigation. They added that the findings of their study could eventually be used to find ways of fighting obesity. Not much has been known about brown fat, a type of good fat, until recently...

Use Of Iodinated Contrast Media In Imaging Procedures Appears To Affect Thyroid Function
Exposure to iodinated contrast media during imaging procedures is associated with changes in thyroid function, and increased risk of developing hyperthyroidism, according to a report in the Archives of Internal Medicine, one of the JAMA/Archives journals. "Iodinated contrast media (ICM) are commonly administered pharmaceutical agents," the authors write as background information...

How Estrogen Influences Mood Changes In Women
Women's emotional responses can vary significantly premenstrually. They may become depressed or grumpy during menstruation or the premenstrual phase, known as premenstrual syndrome (PMS). Roughly 75% of reproductive-age women report premenstrual mood swings or physical discomfort...

Red Wine Versus White Wine - Comparison Of Effects On Hormones Related To Breast Cancer Risk
Aromatase inhibitors (AIs) prevent the conversion of androgens to estrogens, and could play a role in the development of breast cancer. This study of 36 pre-menopausal women consisted of a cross-over intervention trial to determine if there were differences between red wine and white wine in their effects on AIs...

Warning: "Avoid Looking At Pictures Of Appetising Food As It Will Make You Hungry!
Max Planck researchers have proven something scientifically for the first time that laypeople have always known: the mere sight of delicious food stimulates the appetite. A study on healthy young men has documented that the amount of the neurosecretory protein hormone ghrelin in the blood increases as a result of visual stimulation through images of food...

Painful Period Symptoms Reduced By Oral Contraceptive Pill
In the United States, painful periods (Dysmenorrhoea) are estimated to cause 600 million lost working hours and cost two billion dollars in lost productivity...

Researchers Identify Triggering Conditions And Direct Link To Sex Hormones In Sudden Cardiac Death
Researchers in Rhode Island Hospital's Cardiovascular Research Center have published two new studies focusing on the causes of arrhythmia and sudden cardiac death (SCD) when a genetic disorder is present. The studies use a first-ever genetic animal model the researchers developed in 2008 to further their understanding of a genetic disorder known as Long QT Syndrome (LQTS)...
