Neurogenesis plays a beneficial role in exercise-induced response to stress, sexual behavior and reproduction

Two studies published by an interdisciplinary team of Hong Kong researchers in the current special issue of Cell Transplantation (20:1), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/ , link the regrowth of key adult brain cells (neurogenesis) in two critical areas of the brain to both the benefits of exercise as a stress reducer and also to sexual behavior and reproductive issues.

Psychosocially hazardous neighborhood may influence cognitive function in older age

Residing in a psychosocially hazardous neighborhood is associated with worse cognitive function in older age for persons with the apolipoprotein E ε4 allele, according to a report in the March issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

New insight: p53 protein controls molecular crossroads in glucose metabolic pathway

The gene for the protein p53 is the most frequently mutated in human cancer. It encodes a tumor suppressor, and traditionally researchers have assumed that it acts primarily as a regulator of how genes are made into proteins.

Treat discomfort not fever say the new pediatric guidelines

According to a new report from the American Academy of Pediatrics (AAP), fevers alone are not a cause for intervention in children. Dr. Janice Sullivan, the lead author of the report says, “The focus should be on comfort and not on absolute temperature.” That’s because fever can be help fight illness, by slowing down the reproduction of bacteria and viruses or stimulating the body’s immune response she explains. “That’s a benefit of fever…and may shorten the time that your child remains ill,” she adds.

G-CSF treatment improves inadequate endometrium during IVF cycles

During in vitro fertilization cycles, treatment with a medication called granulocyte-colony stimulating factor significantly improves inadequate endometrium, according to a report published electronically on February 15 in Fertility and Sterility - the official journal of the American Society for Reproductive Medicine.

New study: PCBs linked to embryo implantation failure during IVF

According to a new study published February 24 in the peer-reviewed journal Environmental Health Perspectives, serum polychlorinated biphenyls at concentrations found in the general U.S. population are associated with the failure of fertilized embryos to implant in the uterus after in vitro fertilization.

Pretreatment with FDA-approved drug allows successful pregnancies in radiation-exposed rhesus monkeys

A strategy developed by Massachusetts General Hospital (MGH) researchers to shield the ovaries of female mammals from the damaging effects of radiation and chemotherapy has passed an important milestone. A collaborative study with investigators from Oregon Health and Sciences University (OHSU), published online in the journal Fertility and Sterility, reports that brief preexposure of the ovaries to an FDA-approved agent called FTY720 preserved the fertility of female rhesus monkeys exposed to potentially lethal doses of radiation.

New approaches for controlling sleeping sickness caused by trypanosomes

The research could eventually lead to new approaches for controlling sleeping sickness in humans and wasting diseases in livestock which are caused by trypanosomes carried by the bloodsucking tsetse fly.

Skeleton regulates fertility in males, but not females

Researchers at Columbia University Medical Center have discovered that the skeleton acts as a regulator of fertility in male mice through a hormone released by bone, known as osteocalcin.

Researchers find blue-green algae may be responsible for producing estrogen-like compound in water

University of Tennessee, Knoxville, researchers have found that blue-green algae may be responsible for producing an estrogen-like compound in the environment which could disrupt the normal activity of reproductive hormones and adversely affect fish, plants and human health.

Some fat is essential for body function

It's common knowledge that too much cholesterol and other fats can lead to disease, and that a healthy diet involves watching how much fatty food we eat. However, our bodies need a certain amount of fat to function—and we can't make it from scratch.

Researchers describe the complete genome of Daphnia

From an environmental perspective, Daphnia pulex -- the waterflea - is the best-studied organism on the planet. Scientists know how this species responds to pollution, predators, day and night, making it an important model for ecological and evolutionary research. Its genome, however, remained elusive, limiting understanding of how the environment and genes interact.

New strategy needed for monitoring and assessment of marine species

Scientists are having a difficult time gauging the recovery of marine species from the Deepwater Horizon oil spill in the Gulf of Mexico because they lack sufficient data about historical population size and the distribution, growth rates and reproduction rates of many species.
