| Posted: 27 Dec 2011 12:37 PM PST Oxidative stress damages DNA. Researchers have now decoded the mechanism that repairs DNA damaged in this way. This repair mechanism could lead to less invasive approaches in cancer therapy and contribute to the development of new tests for the early diagnosis of cancer. |
| Childhood hypersensitivity linked to OCD Posted: 27 Dec 2011 11:25 AM PST Medical researchers have established a direct correlation between sensory processing and ritualistic behaviors in children. A new study suggests that when children experience heightened levels of sensitivity, they develop ritualistic behaviors to better cope with their environment -- one potential pathway to OCD. |
| Mutation in gene that's critical for human development linked to arrhythmia Posted: 27 Dec 2011 11:25 AM PST The biologic and genetic mechanisms controlling the formation and function of the cardiac conduction system (CCS) are not well understood, but new research with mice shows that altered function of a gene called Tbx3 interferes with the development of the CCS and causes lethal arrhythmias. |
| Sea snails help scientists explore a possible way to enhance memory Posted: 27 Dec 2011 06:31 AM PST Efforts to help people with learning impairments are being aided by a species of sea snail. The mollusk, which is used by researchers to study the brain, has much in common with other species including humans. Neuroscientists have used this animal model to test an innovative learning strategy designed to help improve the brain's memory and the results were encouraging. |
| Women with celiac disease suffer from depression, disordered eating, study finds Posted: 27 Dec 2011 06:30 AM PST Women with celiac disease -- an autoimmune disorder associated with a negative reaction to eating gluten -- are more likely than the general population to report symptoms of depression and disordered eating, even when they adhere to a gluten-free diet, according to researchers. |
| Targeted blocking of cell death prevents fatal condition septic shock, study suggests Posted: 27 Dec 2011 06:29 AM PST Researchers have discovered a new approach to preventing septic shock, an often fatal extreme inflammatory reaction of the body. It is the most frequent cause of death at intensive care departments in hospitals. Researchers have described how blocking a particular form of cell death (necroptosis) fully protects mice against this fatal inflammation. |
| Quality of mother-toddler relationship linked to teen obesity Posted: 26 Dec 2011 06:33 AM PST The quality of the emotional relationship between a mother and her young child could affect the potential for that child to be obese during adolescence, a new study suggests. Researchers analyzed national data detailing relationship characteristics between mothers and their children during their toddler years. The lower the quality of the relationship in terms of the child's emotional security and the mother's sensitivity, the higher the risk that a child would be obese at age 15 years, according to the analysis. |
| Religious beliefs battle hypertension, study of church attendance suggests Posted: 23 Dec 2011 08:40 AM PST Does a belief in God confer any health benefits? Researchers have found a clear relationship between time spent in church and lower blood pressure in both women and men. |
