Risk For Bladder Cancer Increased By 2 Components Of Red Meat Combined With Alteration In DNA Repair
Date: Oct-19-2012Two components of red meat - dietary protein and dietary iron - may combine to form powerful carcinogens, N-nitroso compounds, which increase risk for bladder cancer. Moreover, individuals with reduced ability to reverse the effects of N-nitroso compounds because of a genetic variation in their RAD52 gene could be at particularly high risk. Chelsea Catsburg, a doctoral student at the Keck School of Medicine of the University of Southern California, Los Angeles, presented these data at the 11th Annual AACR International Conference on Frontiers in Cancer Prevention Research, held Oct...
Findings On Cold Virus Proteins May Spur New Cancer Treatments
Date: Oct-19-2012Cold viruses generally get a bad rap - which they've certainly earned - but new findings by a team of scientists at the Salk Institute for Biological Studies suggest that these viruses might also be a valuable ally in the fight against cancer. Adenovirus, a type of cold virus, has developed molecular tools - proteins - that allow it to hijack a cell's molecular machinery, including large cellular machines involved in growth, replication and cancer suppression...
Insights Into How Sleep Deprivation Impacts Dementia, Different Types Of Memory, And Learning
Date: Oct-19-2012New findings just presented report the important role sleep plays, and the brain mechanisms at work as sleep shapes memory, learning, and behavior. The findings were presented at Neuroscience 2012, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health. One in five American adults show signs of chronic sleep deprivation, making the condition a widespread public health problem. Sleeplessness is related to health issues such as obesity, cardiovascular problems, and memory problems...
Imaging Technology Allows Scientists To Link What We Eat To What (And How) We Think
Date: Oct-19-2012Studies just released explore the neurological component of dietary disorders, uncovering evidence that the brain's biological mechanisms may contribute to significant public health challenges - obesity, diabetes, binge eating, and the allure of the high-calorie meal. The findings were presented at Neuroscience 2012, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health...
Basic Social Behaviors Recorded In Distinct Regions Of Social Brain
Date: Oct-19-2012New insights into the wiring and firing of the "social brain" in humans and primates reveals the brain areas important in altruistic motives and behavior, and the brain regions that respond to the pain of discrimination. The findings were presented at Neuroscience 2012, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health. The social brain consists of the structures and circuits that help people understand others' intentions, beliefs, and desires, and how to behave appropriately...
New Disease Subtypes Of Stomach Cancer Revealed Through Epigenetic Analysis
Date: Oct-19-2012Researchers at the Duke-NUS Graduate Medical School in Singapore have identified numerous new subtypes of gastric cancer that are triggered by environmental factors. Reported in the journal Science Translational Medicine, the findings are based on the science of epigenetics, a study of gene activity. The insights into the complexities of stomach cancer could lead to better treatment approaches for the second leading cancer killer in the world, behind lung cancer...
Giving A Voice To Children With ADHD: Study Finds Medication Frees Them To Choose Between Right And Wrong
Date: Oct-19-2012Children living with ADHD tend to feel they benefit from medication to treat the condition and do not think the medication turns them into 'robots', according to a report just published. In fact, they report that medication helps them to control their behaviour and make better decisions. The study, which gives a voice to the children themselves, provides valuable insights into their experiences and the stigma they face...
Social Rejection May Be Linked Through Immune Response To Later Health Outcomes
Date: Oct-19-2012No matter which way you look at it, rejection hurts. Experiencing rejection from a boss, a friend, or a partner is difficult enough for many adults to handle. But adolescents, who are dealing with the one-two punch of biological and social change, may be the most vulnerable to its negative effects...
Link Between Abnormal Involuntary Eye Movements In Amblyopia And Changes In Subcortical Regions Of Brain
Date: Oct-19-2012Little is known about oculomotor function in amblyopia, or "lazy eye," despite the special role of eye movements in vision. A group of scientists has discovered that abnormal visual processing and circuitry in the brain have an impact on fixational saccades (FSs), involuntary eye movements that occur during fixation and are important for the maintenance of vision...
Cost-Effective Treatment For Early Endometrial Cancer Could Be Common Birth Control Device
Date: Oct-19-2012A common birth control device is effective in treating early-stage endometrial cancer in morbidly obese and high-risk surgery patients, said Georgia Health Sciences University Cancer Center researchers, and could lead to a cost-effective treatment for all women with this cancer type. Endometrial cancer, which starts in the lining of the uterus, is the third most common gynecologic cancer, striking more than 47,000 American women every year, particularly the obese. "Total hysterectomy, sometimes with removal of lymph nodes, is the most common treatment for this type of cancer...
