MetaChip provides quick, efficient toxicity screening of potential drugs

A large, multisite trial designed to examine the safety and preliminary effectiveness of two candidate topical microbicides to prevent HIV infection has opened to volunteer enrollment. The trial, sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, represents a partnership among various research institutions in Africa and the U...

Boosting HIV screening can increase survival and is cost effective

Expanded HIV screening can increase patient life span, prevent the spread of the disease, and is cost effective, researchers at Yale, Harvard and the Massachusetts General Hospital report in the February 10 issue of the New England Journal of Medicine (NEJM). .. . "The publication of these papers repre...

Researchers develop assay that could be applied to drug screening

Using state of the art imaging technology a team from Yale School of Medicine has glimpsed one of the cell's most important 'nano-machines' in action. The work, performed in collaboration with English and French scientists, provides new insight into the machinery cells use to internalize cell surface receptors. . All cells traffic protein cargos across their outer membrane, and one of the most im...

Aptamer-based Biosensor screens Air Force personnel and equipment

Air Force personnel will soon know within minutes if they or their equipment are contaminated with a biological agent, thanks to a new technology developed by the Air Force and a national laboratory. .. . "The system will provide an increased capability for Air Force Special Operations personnel to rapidly determine the presence of biological warfare agents in a combat environment," said Dr. Rich...

NIH creates nationwide network of molecular libraries screening centers

The National Institutes of Health (NIH) today announced it is awarding $88.9 million in grants to nine institutions over three years to establish a collaborative research network that will use high-tech screening methods to identify small molecules that can be used as research tools. Small molecules have great potential to help scientists in their efforts to learn more about key biological proces...

Screen all at risk for HIV, plus pregnant women

The new surgical assistant at the University of North Carolina Hospitals arrived in February sporting three arms, a computerized brain and a glowing track record in helping to repair heart valves, remove cancerous prostates, bypass blocked coronary arteries and perform gastric bypass operations for morbid obesity. . .. The robot has been used successfully at UNC for prostate removal surgery...

UT Southwestern researchers develop 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. . .. "Our assay is unique from other conventional ones in its sensitivity and cost- and time-efficiency," sai...

Creeping crinoids! Sea lilies crawl to escape predators, new video shows

.. . But videos taken from a submersible research vessel at a depth of 430 meters (1410 feet) near Grand Bahama Island reveal that some sea lilies ca...

Screening blood for West Nile virus

A recent mandate to screen blood donations in all US states for West Nile virus (WNV) makes little sense from a public health point of view, say researchers from Columbia University and Harvard School of Public Health. . .. WNV can be detected in blood samples by recently developed and approved tests. These tests detect some but not all case...

Mosquito spray increases toxicity of pyrethroids in creek, study finds

A relatively benign compound contained in a widely used group of insecticides can mix with and increase the toxicity of existing pesticides in the environment, according to a new study led by biologists at the University of California, Berkeley. . .. The study's results, reported in the July 26 online edition of Environmental Science & Technology, send a message to environmental regulators t...

Gene screen for breast cancer better than pathologist's 'eye'

Johns Hopkins scientists have found that a method they developed to screen body fluids for certain kinds of cells and some of their genetic blueprint is twice as accurate at spotting breast cancer cells as a pathologist's view with a microscope. . .. Reporting in the June 1 issue of Clinical Cancer Research, the scientists say they have tested their screening tool on breast fluid, in...

Newborn screening can cause unnecessary parental stress

Virtually all babies in the U.S. have their heels pricked soon after birth to get a blood sample for genetic testing. These "heel stick" tests identify rare metabolic disorders before they cause irreversible damage, but as more disorders are added to the screening ?many states now test for 30 or more ?false-positive results are on the rise. In the June issue of Pediatrics, researchers from Childr...

Handling HPV vaccines and screening: The views of 100 authors

Amsterdam, 21 September, 2006 - Elsevier is delighted to announce the publication of a unique supplement to the journal Vaccine: HPV Vaccines and Screening in the Prevention of Cervical Cancer. This special monograph provides a comprehensive and invaluable update for paediatricians, gynaecologists, health educators, policy decision makers, industry and major donor institutions worldwide. . With t...

Pesticides need sunscreen to beat the heat

A pesticide with a new in-built sunscreen will help farmers beat the heat in crop protection. This means that the bug sprays last longer, as they are protected from the strong rays of sunshine, reports Chemistry & Industry, the magazine of the SCI. This is becoming increasingly important as temperatures rise, with the Met Office announcing that several heat records were broken in the UK this...

New sunscreen ingredient to heal sunburn and help prevent skin cancer

People who suffer from sunburn could soon benefit from a new sunscreen ingredient that actively repairs sunburnt skin and helps prevent the onset of skin cancer, according to research published in the Journal of Investigative Dermatology. . .. This reduces the inflammation and pain that goes with sunburn ?which is exacerbated by the iron - and also prevents the build up of harmfu...

Hair-growth drug artificially lowers PSA levels in prostate cancer screening, study finds

The popular hair-growth drug finasteride, taken by millions of balding men, artificially lowers the results of the prostate-specific antigen (PSA) test, the standard screening test for prostate cancer, a multicenter study has found. . The study, involving 308 men ranging in age from 40 to 60 years old, is available online in the British medical journal The Lancet and is scheduled to be published...

Global 'sunscreen' has likely thinned, report NASA scientists

A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases ?sunlight blocked by dust, pollution and other aerosol particles ?appears to have lost ground. . The thinning of Earth’s "sunscreen" of aerosols since the early 1990s could have given an extra push to the rise in global surface temperatures. The finding, published today in the journal Sci...

Childhood obesity among Quebec Cree raises concerns

Childhood obesity is increasing among the general population in Canada, but the statistics are even more alarming among First Nations, Inuit and Métis children. In a study published recently in the American Journal of Public Health, University of Alberta researchers found that up to 65 per cent of Cree preschoolers in northern Quebec communities were overweight or obese. . Dr. Noreen Willows, a c...

Fat screen delivers plant-derived chemical with antidiabetic effects

After screening hundreds of compounds for their effects on fat development, researchers have discovered that an ingredient found in some plants fights diabetes in mice without some of the side effects attributed to other antidiabetes drugs. The chemical they pinpointed, known as harmine, was first isolated more than 150 years ago from plants traditionally included in ritual and medicinal preparat...
