People with recurrent depression or those exposed to chronic stress exhibits shorter telomeres in white blood cells. This is shown by a research team at Umeå University in a coming issue of Biological Psychiatry. The telomere is the outermost part of the chromosome. With increasing age, telomeres shorten, and studies have shown that oxidative stress […]
Studies in institutionalized Romanian children have found that the length of time spent in conditions of social deprivation and neglect correlates with lower IQ and behavioral problems. A new study, led by researchers at Children’s Hospital Boston and Tulane University, shows that early adversity even affects children’s chromosomes – prematurely shortening the chromosome tips, known […]
Adults with post-traumatic stress disorder (PTSD) and a history of childhood trauma had significantly shorter telomere length than those with PTSD but without childhood trauma in a study by researchers at the San Francisco VA Medical Center and the University of California, San Francisco. The results are published in the online Articles in Press section […]
Results of a study presented at the AACR 102nd Annual Meeting 2011, held from April 2-6, lend credence to the idea that improving quality of life affects stress-related biological markers and possibly the health of people with cancer. Researchers know that telomeres shorten and deteriorate with aging, but they are learning that stress also affects […]
Research work carried out at the Hebrew University of Jerusalem arouses a cautionary warning in the growing field of the development of stem cells as a means for future treatment of patients through replacement of diseased or damaged tissues by using the patient’s own stem cells. The research indicates a possible danger of cancerous tissue […]
Positive psychological changes that occur during meditation training are associated with greater telomerase activity, according to researchers at the University of California, Davis, and the University of California, San Francisco. The study is the first to link positive well-being to higher telomerase, an enzyme important for the long-term health of cells in the body. The […]
Research published today provides the first direct evidence that attention-deficit/hyperactivity disorder (ADHD) is a genetic condition. Scientists at Cardiff University found that children with ADHD were more likely to have small segments of their DNA duplicated or missing than other children. Included in this report is a video interview with the lead researcher who discusses […]
New research from the Centre for Addiction and Mental Health (CAMH) and The Hospital for Sick Children (SickKids), both in Toronto, Canada provides further clues as to why Autism Spectrum Disorder (ASD) affects four times more males than females. The scientists discovered that males who carry specific alterations of DNA on the sole X-chromosome they […]
