How can Lyme disease be prevented and controlled? Posted: 04 Jan 2012 02:48 PM PST A new article assesses the potential reasons for the continued lack of success in prevention and control of Lyme disease and identifies areas where additional knowledge could be used to improve Lyme disease prevention and control strategies.

Benefits of statin therapy may extend beyond lowering lipids Posted: 04 Jan 2012 12:37 PM PST A new study has identified a molecular pathway that leads to abnormal cardiovascular blood clotting and turned it off using a popular class of cholesterol-lowering drugs, statins.

New gene that regulates body weight discovered Posted: 04 Jan 2012 12:37 PM PST While studying a brain protein related to the involuntary body movements that are side effects of drugs used to treat Parkinson's disease and schizophrenia, a pharmacy professor discovered that the protein also plays a role in regulating body weight.

Fish oil during pregnancy does not protect against excessive adipose tissue development, study suggests Posted: 04 Jan 2012 12:37 PM PST Is obesity in infants "programmed" in the womb? Previously, researchers assumed that consumption of "bad" fats during pregnancy contribute to excessive infant adipose tissue growth and that "good" omega-3 fatty acids prevent expansive adipose tissue development. A new study showed no evidence to support this "perinatal programming" theory.

No more free rides for 'piggy-backing' viruses Posted: 04 Jan 2012 12:37 PM PST Scientists have determined the structure of the enzyme endomannosidase, significantly advancing our understanding of how a group of devastating human viruses including HIV and Hepatitis C hijack human enzymes to reproduce and cause disease.

inflammatory bowel disease emerges as a global disease Posted: 04 Jan 2012 10:54 AM PST The incidence and prevalence of inflammatory bowel disease are increasing with time and in different regions around the world.

Cancer-killing compound spares healthy cells Posted: 04 Jan 2012 10:48 AM PST Lithocholic acid (LCA), naturally produced in the liver during digestion, has been seriously underestimated. A new study shows that LCA can kill several types of cancer cells, such as those found in some brain tumors and breast cancer.

Experimental vaccine partially protects monkeys from HIV-like infection Posted: 04 Jan 2012 10:48 AM PST New vaccine research in monkeys suggests that scientists are homing in on the critical ingredients of a protective HIV vaccine and identifies new HIV vaccine candidates to test in human clinical trials.

Antiestrogen therapy may decrease risk for melanoma Posted: 04 Jan 2012 08:51 AM PST Women with breast cancer who take antiestrogen supplements may be decreasing their risk for melanoma, according to a new study.

Dried licorice root fights the bacteria that cause tooth decay and gum disease, study finds Posted: 04 Jan 2012 08:51 AM PST Scientists are reporting identification of two substances in licorice -- used extensively in Chinese traditional medicine -- that kill the major bacteria responsible for tooth decay and gum disease, the leading causes of tooth loss in children and adults. In a new study, they say that these substances could have a role in treating and preventing tooth decay and gum disease.

Protein that may represent new target for treating type 1 diabetes identified Posted: 04 Jan 2012 08:50 AM PST Researchers have discovered a new protein that may play a critical role in how the human body regulates blood sugar levels. The research team says the protein may represent a new target for treating type 1 diabetes.

A gene for depression localized Posted: 04 Jan 2012 08:19 AM PST Psychiatric disorders can be described on many levels, the most traditional of which are subjective descriptions of the experience of being depressed and the use of rating scales that quantify depressive symptoms. Over the past two decades, research has developed other strategies for describing the biological underpinnings of depression, including volumetric brain measurements using magnetic resonance imaging and the patterns of gene expression in white blood cells.

Major variation in bladder cancer subtype trends highlights need for focused research Posted: 04 Jan 2012 08:17 AM PST A major study of 128,000 patients has found significant differences between the most common cancer tumors growing inside and on the surface of the bladder. Papillary transitional cell carcinoma rose by 56% between 1973 and 2007 and non-papillary transitional cell carcinoma fell by 53% over the same period, suggest that they may be two disease entities with different causes. This significant finding underlines the importance of future research differentiating between these two subtypes.
