Clotrimazole drug used to treat skin conditions is a marine pollutant

Clotrimazole is a common ingredient in over-the-counter skin creams. Recent results from the University of Gothenburg, Sweden, now show that it is associated with major environmental risks. "The pharmaceuticals and chemicals in everyday use form a mixture in the ocean that has a direct impact on the growth and reproduction of organisms", says scientist Tobias Porsbring.

Environmental cardiology - the relationship between air pollution and heart disease

We are used to thinking of heart disease as a product of genetic factors or lifestyle choices, such as what we eat and how much we exercise.

Human adult testes cells can become embryonic-like

Using what they say is a relatively simple method, scientists at Georgetown University Medical Center have extracted stem/progenitor cells from testes and have converted them back into pluripotent embryonic-like stem cells.

Tiny genetic change keeps nicotine from binding to muscle cells

A tiny genetic mutation is the key to understanding why nicotine--which binds to brain receptors with such addictive potency--is virtually powerless in muscle cells that are studded with the same type of receptor.

Gulf War veterans display abnormal brain response to specific chemicals

A new study by UT Southwestern Medical Center researchers is the first to pinpoint damage inside the brains of veterans suffering from Gulf War syndrome - a finding that links the illness to chemical exposures and may lead to diagnostic tests and treatments.

Quantum effect may hold promise for low-cost DNA sequencing, sensor applications

A ghostly property of matter, called quantum tunneling, may aid the quest for accurate, low-cost genomic sequencing, according to a new paper in Nature Nanotechnology Letters by Stuart Lindsay and his collaborators at the Biodesign Institute of Arizona State University.

Naltrexone can reduce relapse rates among alcohol-dependence patients

Naltrexone, an opioid antagonist approved in 1994 by the U.S. Food and Drug Administration for alcohol-dependence (AD) treatment, can reduce relapse rates among AD patients.

Discovery of new pathway that regulates inflammation

Inflammation, the body's earliest response to damage or infection, can aid the healing process and trigger an immune response against invading pathogens.

Researchers probe mechanisms of infection

A newly discovered receptor in a strain of Escherichia coli might help explain why people often get sicker when they're stressed.

How chemicals present in cranberries prevent urinary tract infections

Chemicals present in cranberries - and not the acidity of cranberry juice, as previously thought - prevent infection-causing bacteria from attaching to the cells that line the urinary tract, as documented in a report published in Journal of Medicinal Food.

Human sweat contains emotional meanings

When threatened, many animals release chemicals as a warning signal to members of their own species, who in turn react to the signals and take action.

Powder-free latex gloves decrease allergy risk in hospitals

Using powder-free latex gloves rather than those with cornstarch powder greatly reduced the number of workers' compensation claims related to latex-related illness, a recent Geisinger study found.

FDA shuts down a flour tortilla manufacturer for repeated violations

The U.S. Food and Drug Administration (FDA) has announced that Del Rey Tortilleria Inc., Chicago, Ill., its president, and two general managers have entered into a consent decree of permanent injunction that prevents Del Rey Tortilleria from manufacturing and distributing soft-shell flour tortillas until the company obtains FDA approval.

Research trial call for pregnant smokers

Mums-to-be across the East Midlands are being invited to take part in research that aims to establish whether nicotine patches are safe and effective for pregnant smokers.

Drugs that act on 'fasting signal' may curb insulin resistance in obese

A report in the March issue of Cell Metabolism , a Cell Press publication, has found that a signal known to play a role during fasting also switches on early in the fat tissue of obese mice as they progress toward type 2 diabetes.

Instant immunity through chemically programmable vaccination and covalent self-assembly

The experiments, thus far performed only in mice, appear to overcome a major drawback of vaccinations - the lag time of days, or even weeks, that it normally takes for immunity to build against a pathogen.

Protein complex shown to play pivotal role in stem cell development

Scientists at the Stanford University School of Medicine have identified a protein complex important in controlling whether embryonic stem cells retain their ability to become any cell in the body - a quality called pluripotency - or instead embark on a pathway of maturation and specialization.

Scientists develop general-purpose method for detecting trace chemicals

Described in an advance, online publication of the journal Nature Biotechnology on February 22, 2009, the team's general method could be adapted for detecting a wide variety of compounds, including many that are relevant to diagnostic medicine and environmental work.
