Progress made toward a genital herpes vaccine Posted: 04 Jan 2012 02:48 PM PST New research points investigators toward finding a genital herpes vaccine that works on both viruses that cause disease.

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.

Guidelines stress caution when combining anti-epileptic, HIV drugs Posted: 04 Jan 2012 02:48 PM PST New guidelines will help physicians better choose seizure drugs for people on HIV/AIDS medication, avoiding deadly drug interactions and preventing critical anti-HIV drugs from becoming less effective, possibly leading to a more virulent strain of the disease.

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.

Updated rotavirus vaccine not linked to increase in bowel obstruction, research shows Posted: 04 Jan 2012 10:54 AM PST The rotavirus vaccine was pulled from the marketplace in 1999 after being associated with painful gastrointestinal complications, however, the updated rotavirus vaccines do not appear to increase the occurrence of these potentially fatal side effects, according to a new study by child health experts.

Simple online tool to aid GPs in early ovarian cancer diagnosis Posted: 04 Jan 2012 10:54 AM PST The lives of hundreds of women could be saved every year, thanks to a simple online calculator that could help GPs identify women most at risk of having ovarian cancer at a much earlier stage.

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.

Exercise is good for your waistline -- but it's a writing exercise Posted: 04 Jan 2012 10:48 AM PST Is losing weight as simple as doing a 15-minute writing exercise? In a new study, women who wrote about their most important values, like close relationships, music, or religion, lost more weight over the next few months than women who did not have that experience.

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.

The cost of disabilities could reach 77.2% of household income Posted: 04 Jan 2012 10:31 AM PST Researchers have for the first time estimated the cost and impact of disabilities on the finances of disabled people. According to data, 90% of the population with a serious disability in Spain is in a state of moderate poverty and 56% lives in a state of extreme poverty.

Hypothermia underutilized in cardiac arrest cases treated in U. S. hospitals, study suggests Posted: 04 Jan 2012 10:31 AM PST Therapeutic hypothermia has been proven to reduce mortality and improve neurologic outcomes after a heart attack, yet it was rarely used in a sample of more than 26,000 patients, according to a new study.

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.

Blogging may help teens dealing with social distress Posted: 04 Jan 2012 08:51 AM PST Blogging may have psychological benefits for teens suffering from social anxiety, improving their self-esteem and helping them relate better to their friends, according to new research.

Older, cheaper vacuum cleaners release more bacteria and dust Posted: 04 Jan 2012 08:51 AM PST Some vacuum cleaners -- those basic tools for maintaining a clean indoor environment in homes and offices -- actually contribute to indoor air pollution by releasing into the air bacteria and dust that can spread infections and trigger allergies, researchers report in a new study.

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.

Experts urge BMI method for calculating weight in kids with eating disorders Posted: 04 Jan 2012 08:18 AM PST Researchers compared three common methods for calculating expected body weight of adolescents with eating disorders and found that the body mass index percentile method is recommended for clinical and research purposes.

Impaired quality of life: A warning signal after esophageal cancer surgery Posted: 04 Jan 2012 08:17 AM PST A new study shows that most patients who survive for at least five years after esophageal cancer surgery recover an average quality of life. However, quality of life deteriorates significantly for one in six patients to a level that remains much lower than the average population in the five years after surgery. This suggests, say the researchers, that hospitals must be better at identifying this patient group.

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.
