Research Links Poor Semen Quality To Higher Danger Of Various Health Problems

10 in Fertility and Sterility, may spur more-comprehensive approaches to treating male infertility. They also point to the wisdom of performing complete physical examinations of men experiencing reproductive difficulties. "About 15 percent of all couples have fertility issues, and in half of those cases the male partner has semen deficiencies," said the study's lead author, Michael Eisenberg, MD, assistant professor of urology and director of male reproductive medicine and surgery at Stanford. "We should be paying more attention to these millions of men. Infertility is a warning: Problems with reproduction may mean problems with overall health." A study Eisenberg co-authored a few years ago showed that infertile men had higher rates of overall mortality, as well as mortality linked to heart problems, in the years following an infertility evaluation.

Researchers suggest new strategy to control cellular identity and fate

Yi Xing, a UCLA associate professor of microbiology, immunology and molecular genetics, led the informatics analyses and was a co-corresponding author of the paper. Other corresponding authors were Dr. Cosmas Giallourakis, an assistant professor of medicine at Harvard Medical School and Massachusetts General Hospital, and Dr. Howard Chang, a professor of Stanford University's School of Medicine and a Howard Hughes Medical Institute investigator. The study of naturally occurring chemical modifications on RNAs is part of an emerging field known as epitranscriptomics. The m6A tag is the most commonly occurring modification known to scientists; it is found on RNAs of thousands of protein-coding genes and hundreds of non-coding genes in a typical cell type.

Study sheds new light on well-known mechanism required for immune response

Research findings may lead to new ways to thwart drug resistance Research findings may lead to new ways to thwart drug resistance Published on December 6, 2014 at 3:22 AM · No Comments Scientists reveal how penicillin deals bacteria a devastating blow -- work that may lead to new antibiotics Penicillin, the wonder drug discovered in 1928, works in ways that are still mysterious almost a century later. One of the oldest and most widely used antibiotics, it attacks enzymes that build the bacterial cell wall, a mesh that surrounds the bacterial membrane and gives the cells their integrity and shape. Once that wall is breached, bacteria die -- allowing us to recover from infection. That would be the end of the story, if resistance to penicillin and other antibiotics hadn't emerged over recent decades as a serious threat to human health. While scientists continue to search for new antibiotics, they still don't understand very much about how the old ones work. Now Thomas Bernhardt, associate professor of microbiology and immunobiology at Harvard Medical School, and his colleagues have added another chapter to the story.
