Nitric oxide could one day help women in their 30s and 40s remain fertile longer

Researchers have found that an important chemical compound, nitric oxide, appears to slow or reverse the aging of eggs in mouse ovaries. The finding suggests nitric oxide could one day help women in their 30s and 40s remain fertile longer and increase their chances of having healthy babies, the scientists say.

MRC call for proposals in experimental medicine

The Medical Research Council (MRC) has launched a Call for Proposals in experimental medicine today as part of its £15 million commitment to promote the translation of laboratory research into clinical practice for the benefit of patients.

Methoxychlor (MXC) may interfere with proper development and function of the reproductive tract, leading to reduced fertility in women

The researchers found that MXC, which was manufactured as a safer replacement for the now-banned DDT, alters the estrogen-regulated gene Hoxa10 in the reproductive tract and reduces the ability of the uterus to support embryo implantation. The researchers used mice and then human cell lines to confirm their findings.

Anorexia may be caused by change in brain chemical

A new study has found that women who have had a certain type of anorexia nervosa show a change in the activity of a chemical in their brain that is widely associated with anxiety and other affective disorders, for as long as one year after recovery.

Third-year medical students receive on average one gift or attend one activity sponsored by a pharmaceutical company per week

...and most believe that sponsored educational events are likely to be biased, according to an article in the September 7 issue of JAMA: The Journal of the American Medical Association, a theme issue on medical education.

Enrollment at U.S. medical schools has changed very little over the last 10 years

The authors found that the number of medical students in 1994-1995 and in 2004-2005 remained constant, at about 67,000. The number of full-time faculty members increased from 90,016 in 1994-1995 to 119,025 in 2004-2005 (a 32 percent increase).

Study indicates that patients with a cervical spinal injury may harbor additional spinal damage not visible on regular x-rays

In fact, more than a third of patients who were thought to have low-risk injuries actually have additional damage that may include significant fractures with the potential to produce serious spinal problems if not detected and treated properly.

WHO urges responsible use of antimalarial medicines

In a new report published today, ''Susceptibility of Plasmodium Falciparum to Antimalarial Drugs,'' the World Health Organization (WHO) warns that as more and more people gain access to these life-saving malaria medicines, which combine a drug derived from the plant Artemisia annua with a second, synthetic drug, it is vital that countries closely monitor their effectiveness.

Testing for specific breast cancer genes unadvisable if no family history of disease exists

According to the Preventive Services Task Force in the U.S., routine testing for mutations in the BRCA1 and BRCA2 genes, which have been linked to breast and ovarian cancer, are not advised unless women have a family history of the disease.

Researchers uncover how the inhaled form of anthrax disarms bacteria-fighting white blood cells before they can fend off the disease

The lethal toxin in anthrax paralyzes neutrophils, the white blood cells that act as the body's first defense against infection, by impairing how they build tiny filaments that allow them to crawl throughout the body and eat invading bacteria.

Anorexia nervosa linked with alteration of the activity of serotonin in their brain

Women who have had a certain type of anorexia nervosa show an alteration of the activity of a chemical in their brain that is widely associated with anxiety and other affective disorders more than one year after recovery, according to a study in the September issue of Archives of General Psychiatry.

Human embryonic stem cell lines accumulate changes in their genetic material over time

The findings do not limit the utility of the cells for some types of research or for some future clinical applications, the researchers say, but draw attention to the need to closely monitor stem cell lines for genetic changes and to study how these alterations affect the cells' behavior.

Osteopontin protein found to be more common in patients with lung fibrosis

Idiopathic pulmonary fibrosis (IPF) is a scarring disease without a cure, irreparably damaging the ability of the tissue to transfer oxygen into the bloodstream.

Profile of immune cells in axillary lymph nodes predicts disease-free survival in breast cancer

Breast cancer often spreads through the lymph nodes in the arm pits (so-called axillary lymph nodes), and whether these lymph nodes are tumor-free or contain small metastases is an important factor in the decision of how aggressively to treat a patient.

Soldiers at risk for heat illnesses

A study reviewing 22 years of data on heat illness hospitalizations and deaths in the U.S. Army indicates soldiers remain at risk for exertional heat illness. While hospitalization rates for heat illnesses have declined over this period, cases of heat stroke have increased.

Shot in the arm for vaccines

A Flinders University research program to develop new forms of vaccine against infectious diseases has received over $3 million in funding from the United States Government's National Institutes of Health.

Observation of adult behavior may influence preschool children to view smoking as normal

When pretending to shop for a social evening, children two to six years old were nearly four times as likely to choose cigarettes if their parents smoked and children who viewed PG-13- or R-rated movies were five times as likely to choose wine or beer, according to a study in the September issue of Archives of Pediatrics & Adolescent Medicine.

New ways to enhance or block fertilization

Researchers have capitalized on the unique properties of a sperm cell to follow cell membrane fusion as it occurs during fertilization, tracking the full cascade of events for the first time. The findings could reveal new ways to enhance or block fertilization, as well as how to control the secretion of neurotransmitters and hormones such as insulin.
