Mitochondrial DNA mutations play significant role in prostate cancer
Mutations in mitochondrial DNA (mtDNA) playan important role in the development of prostate cancer, according toresearch by scientists at Emory University School of Medicine and theUniversity of California, Irvine. The findings are published onlinethis week in the Proceedings of the National Academy of Sciences(PNAS). Mitochondrial DNA, which is separate from nuclear DNA, is foundin the hun...Female sex hormones play a vital role in defense against sexually transmitted diseases
Two McMaster University studies, to be published in the Journal of Virology, show that sex hormones have a profound effect on susceptibility of female mice to the herpes simplex virus, type 2 (HSV-2 ), one of the most common sexually transmitted diseases. Charu Kaushic, assistant professor and supervisor of the studies, says the implication of this work is quite significant. "The research...An HIV Protein Plays a Surprising Role in Gene Activation
Retroviruses are expert manipulators when it comes to co-opting their host's cellular resources. A great deal of human complexity stems from the vast repertoire of proteins and mechanisms dedicated to the business of regulating gene expression, and retroviruses like HIV have evolved myriad ways of redirecting that machinery to their own benefit. Humans and other eukaryotes have three type...Critical role in programmed cell death identified
Dartmouth Medical School geneticists have found links in the cell death machinery of worms and mammals, opening new avenues for studying and targeting a process vital to development and implicated in cancer and autoimmune diseases. The work, reported in the February 17 issue of Nature, demonstrates the role of mitochondria, the cellular power plant, in prompting worm cells to self destruc...White blood cell waste disposal system plays critical regulatory role
A new research study identifies a critical inhibitory step that is a key component of the feedback circuit regulating the balance between neutrophil production and destruction. The research, published in the March issue of Immunity, suggests that the process for disposal of dying neutrophils is actively linked to neutrophil production. A clear understanding of the processes that control neutrophi...Chemical-petroleum executive joins Virent Energy board

According to Pediatrics journal, a new study states that teenagers who use the media with high sexual content have twice the chance to have sex by the time they are 16 than// those kids who use the media lesser. There seems to be a marked increased of sexual activity among the teenagers between 12 and 14, who are more exposed to media. Researchers at the University of North Carolina at...Role of fats and oils in vision care
The balance of fats and oils in your diet can affect your vision, according to a new study. Age-related macular degeneration (AMD) is a currently untreatable disease of the eye causing fuzziness, shadows and severe visual impairment. As the name suggests, it gets worse with age and diet has been implicated in its development. // Researchers at the Massachusetts Eye and Ear Infirmary c...Antidepressants-important role
According to a new study, there is no significant difference between three commonly prescribed drugs for depression. The selective serotonin reuptake inhibitors (SSRIs) are now very widely used in the treatment of depression.// They raise levels of a brain chemical called serotonin that plays an important role in mood. But there is no evidence on how individual SSRIs compare with one anot...The Prolex E.coli O157 Latex Test Reagent Kit
