Media Tool Empowers Children to Skirt Alcohol

Media Tool Empowers Children to Skirt Alcohol
Playing "media detective" allows children to understand the intentions of marketers and the goals of advertising while empowering them to resist messages that encourage alcohol or tobacco use. A study reported in the current journal Pediatrics shows that teaching children as early as third grade to be more skeptical of media messages can help prevent substance use. The study, based on the research of Erica Weintraub Austin, director of the........Go to the Society medical news blog (Added on 8/24/2010 7:16:47 AM)


Genetic variation linked to lupus

Genetic variation linked to lupus
Genes reside along long chains of DNA called chromosomes. UCLA scientists have observed that a variation in a gene on the sex chromosome X may enhance an immune response that leads to lupus in men. Systemic lupus erythematosus (SLE) is an autoimmune disease that predominantly affects women. Interestingly, scientists observed that eventhough the variation occurred in a gene on the X, or female, chromosome, its influence was stronger in men........Go to the Rheumatology news blog (Added on 8/24/2010 7:10:14 AM)


Protein made by breast cancer gene purified

Protein made by breast cancer gene purified
A key step in understanding the origins of familial breast cancer has been made by two teams of researchers at the University of California, Davis. The scientists have purified, for the first time, the protein produced by the breast cancer susceptibility gene BRCA2 and used it to study the oncogene's role in DNA repair. The results will be published online Aug. 22 in the journals Nature, and Nature Structural and Molecular Biology. They open........Go to the Breast-cancer-blog (Added on 8/23/2010 7:14:19 AM)


Rectal cancer rates are rising

Rectal cancer rates are rising
A new analysis has observed that while colon cancer rates have remained steady over the past several decades among people under the age of 40, rectal cancer rates are increasing in this population across races and in both sexes. Published early online in Cancer, a peer-evaluated journal of the American Cancer Society, the study indicates that greater efforts are needed to diagnose rectal cancer in young individuals who show potential signs of........Go to the Cancer-blog (Added on 8/23/2010 7:11:26 AM)


Natural vaccine against malaria

Natural vaccine against malaria
A study reported in the journal Science Translation Medicine proposes that preventative therapy with affordable and safe antibiotics in people living in areas with intense malaria transmission has the potential to act as a 'needle-free' natural vaccine against malaria and may likely provide an additional valuable tool for controlling and/or eliminating malaria in resource-poor settings.

Hear sounds in cardiac failure

Hear sounds in cardiac failure
For emergency department patients with shortness of breath and a risk of heart failure, physicians usually grab one thing first: a stethoscope. It allows them to hear the S3, an abnormal third sound in the heart's rhythm strongly associated with cardiac disease and heart failure. However, the low-frequency, low-pitch sound is notoriously very difficult to hear with a stethoscope alone.

Menstrual cramps on brain structure

Menstrual cramps on brain structure
Primary dysmenorrhea (PDM), or menstrual cramps, is the most common gynecological disorder in women of childbearing age. Lower abdominal pain starts with the onset of menstrual flow and this ongoing pain stimulus can cause alterations throughout the nervous system. In a study scheduled for publication in the recent issue of PAIN, scientists report abnormal changes in the structure of the brain in PDM patients, whether or not they are in fact........Go to the OBGYN news blog (Added on 8/11/2010 6:58:22 AM)

His innovative method, soon to be reported in the journal Nanomedicine, uses heat to kill the tumor cells but........Go to the Cancer-blog (Added on 8/10/2010 7:06:33 AM)


How to fix a broken heart?

How to fix a broken heart?
These days people commonly don't die from a heart attack. But the damage to heart muscle is irreversible, and most patients eventually succumb to congestive heart failure, the most common cause of death in developed countries. Stem cells now offer hope for achieving what the body can't do: mending broken hearts.

Unlocking Secret of Rabies

Unlocking Secret of Rabies
Most infectious diseases infect multiple host species, but to date, efforts to quantify the frequency and outcome of cross-species transmission (CST) of these diseases have been severely limited. This lack of information represents a major gap in knowledge of how diseases emerge, and from which species they will emerge.

Brain connections break down as we age
It's unavoidable: breakdowns in brain connections slow down our physical response times as we age, a newly released study suggests.
