Compounds secreted by frog skin are potent blockers of HIV infection

The findings could lead to topical treatments for preventing HIV transmission, and they reinforce the value of preserving the Earth's biodiversity.

Plant-derived compounds appear to block the activity of an enzyme that triggers inflammation in joints

The findings came to light while the researchers were studying the wildly different ways in which cells in human blood vessels and joints respond to pressure gradients generated from liquid moving along their surface, a force called shear stress.

Nicotine has an unusual psychological property that may drive dependence

Associate Professor Athina Markou, Ph.D., who is in the Scripps Research Molecular and Integrative Neurosciences Department at Scripps Research’s La Jolla Campus, and Paul Kenny, Ph.D., a former Research Associate in her laboratory, report in an upcoming issue of the journal Neuropsychopharmacology that nicotine has an unusual psychological property that may drive dependence.

Nanoparticles as an invisible diet

Utah State University researchers are in the early stages of scientifically tricking the body into eating less and finding a treatment for obesity without dangerous side effects.

Fndings could lead to a treatment for idiopathic interstitial pneumonia

An incurable, deadly lung disorder, "idiopathic interstitial pneumonia" (IIP), whose causes were mysterious arises from a combination of a genetic predisposition and damage due to inhaled chemicals, notably from cigarette smoking, Duke University Medical Center researchers have found.

Computer program helps explain how the same proteins can play different roles in a wide range of cellular processes

University of California, San Diego biochemists have developed a computer program that helps explain a long-standing mystery: how the same proteins can play different roles in a wide range of cellular processes, including those leading to immune responses and cancer.

Israeli scientists successfully transplant ovaries in sheep and trigger early embryonic development

Israeli scientists report in Human Reproduction that they have successfully transplanted whole frozen and thawed ovaries in sheep, retrieved oocytes from these ovaries and triggered them in the laboratory into early embryonic development.

Presence of environmental chemicals in human milk does not necessarily indicate health risks for infants

"We strongly emphasize that the mere presence of an environmental chemical in human milk does not indicate that a health risk exists for breast-fed infants," said Cheston M. Berlin, Jr., M.D., Penn State University professor of pediatrics and pharmacology.

Significant death risk linked to airborne particles

Experts may be significantly underestimating air pollution's role in causing early death, according to a team of American and Canadian researchers, who studied two decades' worth of data on residents of the Los Angeles metro area.

Low-dose aspirin might prevent the cardiovascular damage known to arise from use of the painkiller rofecoxib (Vioxx)

Their findings that a chemical imbalance might underlie such damage could also lead to the development of anti-inflammatory drugs without the adverse side effects, the researchers said.

Compounds found in broccoli, cauliflower, and watercress block lung cancer progression

A family of compounds found in cruciferous vegetables, such as broccoli, cauliflower, and watercress, blocked lung cancer progression in both animal studies and in tests with human lung cancer cells, report researchers from Georgetown University Medical Center and the Institute for Cancer Prevention.

Methoxychlor (MXC), a common insect pesticide may lead to reduced fertility in women

Methoxychlor (MXC), a common insect pesticide used on food crops, may interfere with proper development and function of the reproductive tract, leading to reduced fertility in women, researchers at Yale School of Medicine write in the August issue of Endocrinology.

Screening test for cells that activate immune system

UT Southwestern Medical Center researchers are the first to create a large-scale, cell-based screening method that identifies which compounds activate immune-response cells that hold promise for future cancer-fighting vaccines.

Scientists characterize the most infectious prion protein particles

A new study of prions - apparently malformed proteins that initiate deadly brain diseases such as Creutzfeldt-Jakob disease in humans - has yielded surprising information about how the size of prions relates to their infectivity.

Cannabis drug could help fight obesity

Apparently scientists have discovered that a natural component of cannabis suppresses the appetite and that discovery may lead to a new class of drugs for treating obesity.

Bacteria lurking in household dust produce chemicals that may trigger asthma

These bacterial chemicals, called endotoxins, particularly those found on bedroom floors, were linked with increased respiratory problems in adults.

Call for more donations of brains to help researchers discover new treatments for neurological disorders

Speaking at the BA Festival of Science, at Trinity College, Dublin, Dr Kirstin Goldring from Imperial College London and Charing Cross Hospital is calling for more donations of brains to help researchers discover new treatments for neurological disorders.

7 Sep 2005

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.

Animal model of Parkinson's disease reveals striking sensitivity to common environmental toxins

In findings that support a relationship between agricultural chemicals and Parkinson's disease, two groups of researchers have found new evidence that loss of DJ-1, a gene known to be linked to inherited Parkinson's disease, leads to striking sensitivity to the herbicide paraquat and the insecticide rotenone.
