Prostate Cancer :: Soy found protective against localized prostate cancer
The largest study examining the relationship between the traditional soy-rich Japanese diet and development of prostate cancer in Japanese men has come to a seemingly contradictory conclusion: Intake of isoflavone chemicals, derived largely from soy foods, decreased the risk of localized prostate cancer but increased the risk of advanced prostate cancer.
Heart Disease :: Researchers find heart disease in a marathon runner — is too much exercise a bad thing?
Doctors at the University of Maryland Medical Center had a mystery on their hands. A 51-year-old physician colleague who looked the picture of health?no cardiovascular risks, a marathon runner who had exercised vigorously each day for 30 years?had just flunked a calcium screening scan of his heart.
Screening :: Screening reduces sudden cardiac death rate in young athletes
A 12-point screening process could help reduce sudden cardiac death in high school and college competitive athletes, according to an updated American Heart Association scientific statement.
HIV :: ICC Cricket World Cup West Indies 2007 to highlight HIV
The International Cricket Council (ICC) will team up with UNAIDS, UNICEF and the Caribbean Broadcast Media Partnership on HIV/AIDS at the ICC Cricket World Cup 2007 to highlight the situation of children and young people living with and affected by HIV.
Depression :: Stress and nerve cells survival in rats, finding may open window for depression treatment
A single, socially stressful situation can kill off new nerve cells in the brain region that processes learning, memory and emotion, and possibly contribute to depression, new animal research shows.
DNA :: Stability of mRNA/DNA and DNA/DNA duplexes modulates mRNA transcription
The distribution of the four nucleotides along the DNA sequence encodes the genetic information in living systems. However, do nucleic acids possess other attributes that contribute to their biological functions? Recent work of a team led by Stoyno Stoynov, working at the Bulgarian Academy of Sciences, suggests that thermodynamic stability of DNA/DNA and RNA/DNA duplexes influences mRNA transcription. The manuscript appears in the March 14 issue of the international, peer-reviewed, open-access online journal PLoS ONE.
Smoking :: A short walk helps smokers quit
Smokers should do short bouts of exercise to help them resist the temptation to light up, say experts at the University of Exeter. A review, recently published in the international journal “Addiction,” concludes that when smokers abstain from smoking, exercise can help them to manage withdrawal symptoms and resist the urge to smoke.
Health Care :: Health care system for aging nerve cells
Uncontrolled neuronal death in the brain often gives rise to neurodegenerative illnesses like Parkinson or Alzheimer disease. Whether or not neurons have a long and healthy life is, apart from other factors, determined by the presence of neurotrophic factors. Scientists of the Max Planck Institute of Neurobiology have now provided unambiguous proof that the presence of the neurotrophic factor GDNF and its receptor Ret are essential for the survival of neurons in a specific brain region.
Cancer :: New cell type identified in cancer development
Scientists have discovered a new type of cell that appears to play a role in the development of cancer ? a highly volatile, precancerous stem cell that can either remain benign or become malignant, depending upon environmental cues.
