PTSD is Linked to Other Diseases in Fundamental and Surprising Ways

Gendron Recheche, #Cancer Post-traumatic stress disorder (PTSD) has become a prominent concern in American medical institutions and the culture at-large, with a new generation of military veterans returning home from Afghanistan and Iraq. Estimates indicate that as many as 35 percent of personnel deployed to Iraq and Afghanistan suffer from PTSD. New research from the University of South Carolina School of Medicine is shedding light on how PTSD is linked to other diseases in fundamental … http://dlvr.it/5Tjdnf

Hundreds of Genetic Mutations Found in Healthy Individuals

Gendron Recheche, #Cancer Genetic mutations are commonly studied because of links to diseases such as cancer. However, very little is known about mutations occurring in healthy individuals. In a study published online in iGenome Research/i, researchers detected over 400 mutations in healthy blood cells of a 115-year-old woman, suggesting that lesions at these sites are largely harmless over the course of a lifetime. Our blood is continually replenished by hematopoietic stem … http://dlvr.it/5Tjdk1

Guidelines for Genomics Studies

Gendron Recheche, #Cancer Leading to an explosion of studies comparing the genomes of people with and without a given disease, sequencing an entire human genome is faster and cheaper than ever before. Often clinicians and researchers studying genetic contributions to a certain disease encounter variations that appear to be responsible, only to find other people with the same mutation who don’t have the disease or who are affected to a lesser degree. How do doctors pinpoint the … http://dlvr.it/5Tjddm

Genes on the Y Chromosome Prove Essential for Survival of Men

Gendron Recheche, #Cancer The human Y chromosome has over the course of millions of years of evolution managed to preserve a small set of genes that has ensured not only its own survival but also the survival of men, despite a well-documented history of dramatic genetic decay. Moreover, the vast majority of these tenacious genes appear to have little if any role in sex determination or sperm production. Taken together, these remarkable findings-published this week in the journal … http://dlvr.it/5TjdYp

Scientists Find New Target for Prostate Cancer Treatment

Gendron Recheche, #Cancer When anti-hormone treatments stop working, then prostate cancer becomes deadly. Now a new study suggests a way to block the hormones at their entrance. Researchers from the University of Michigan Comprehensive Cancer Center have found that a protein called BET bromodomain protein 4 binds to the hormone androgen receptor downstream of where current therapies work - targeting androgen receptor signaling. This could mean that when prostate cancer becomes … http://dlvr.it/5TjdSN

Some Astronauts at Risk for Cognitive Impairment: Study

Gendron Recheche, #Cancer Rats exposed to high-energy particles, simulating conditions astronauts would face on a long-term deep space mission, show lapses in attention and slower reaction times, even when the radiation exposure is in extremely low dose ranges, report Johns Hopkins scientists. The cognitive impairments - which affected a large subset, but far from all, of the animals - appear to be linked to protein changes in the brain, the scientists say. The findings, if found to hold … http://dlvr.it/5Tj7d4

Scientists Discover Supermassive Black Holes

Gendron Recheche, #Cancer An international team of researchers has discovered a pair of supermassive black holes in orbit around one another. This is the first time such a pair could be found in an ordinary galaxy. They were discovered because they ripped apart a star when ESA’s space observatory XMM-Newton happened to be looking in their direction. On 10 June 2010, a tidal disruption event was spotted by XMM-Newton in galaxy SDSS J120136.02+300305.5, approximately 2 billion … http://dlvr.it/5Thf8z

Autologous Stem Cell Therapy Improves Motor Function in Stroke Patients

Gendron Recheche, #Cancer Stroke patients often suffer motor deficits with little potential to restore neurological function. However, a study conducted in Taiwan, that will be published in a future issue of emCell Transplantation/em, but is currently freely available on-line as an unedited early e-pub at: http:www.ingentaconnect.com/content/cog/ct/pre-prints/content-ct1168Chen, has found that when one group of stroke victims had their own peripheral blood stem cells (PBSCs) injected … http://dlvr.it/5Thf5K

Post-Apartheid World South Africa’s Institutions Crumbling Down

Gendron Recheche, #Cancer Emergency surgeries are carried out by the light of a cellphone and seriously ill patients are laid down 3 on a bed in Africa’s largest hospital. Twenty years after South Africans jubilantly swept apartheid aside, Johannesburg’s Chris Hani Baragwanath Hospital, like many of the country’s post-apartheid institutions, has failed to live up to the dream. Away from the country’s high-profile political scandals, a more pernicious institutional crisis is … http://dlvr.it/5Thf1K
