Formaldehyde is a colorless, flammable, strong-smelling chemical that is used to manufacture building materials and to produce many household products. Formaldehyde sources in the home include pressed-wood products, cigarette smoke, and fuel-burning appliances. When exposed to formaldehyde, some individuals may experience various short-term health effects. Formaldehyde has been classified as a known human carcinogen (cancer-causing substance) by the International Agency for Research on Cancer and as a probable human carcinogen by the U.S. Environmental Protection Agency. Research studies of workers exposed to formaldehyde have suggested an association between formaldehyde exposure and cancers of the nasal sinuses, nasopharynx, and brain, and possibly leukemia.
Adding to growing evidence on the possible health risks of electronic cigarettes, a lab team at the Veterans Affairs San Diego Healthcare System tested two products and found they damaged cells in ways that could lead to cancer. The damage occurred even with nicotine-free versions of the products.
Diacetyl, a flavoring chemical linked to cases of severe respiratory disease, was found in more than 75% of flavored electronic cigarettes and refill liquids tested by researchers at Harvard T.H. Chan School of Public Health.
An interview with Gary Broomhead, discussing the potential sources of contamination in research and how controlling airflow in the laboratory can reduce this.
Most people think of allergists as the doctors who help solve sneezing, wheezing and itchy eyes. They might not realize allergists are the medical mystery detectives with the expertise to discover what is causing all sorts of unusual allergic responses.
During the next three years, researchers at Case Western Reserve University will team with NASA Glenn Research Center and firefighters nationally, from Cleveland to Oregon, to design and test sensors aimed at protecting firefighters from respiratory damage and illnesses.
Most of the debate around e-cigarettes has focused on the developed world, but the devices are becoming more widely available in some low- and middle-income countries, where there is even greater potential for impact on public health, say two Stanford University School of Medicine researchers.
An algorithm dubbed ENVE could be the Google for genetic aberrations — and it comes from Case Western Reserve.
Smokeless tobacco and, more recently, e-cigarettes have been promoted as a harm reduction strategy for smokers who are "unable or unwilling to quit."
Biomedical engineers at the University of Toronto have invented a new device that more quickly and accurately "listens in" on the chemical messages that tell our cells how to multiply.
Chromatrap®, a business unit of Porvair Sciences, has introduced a new Formaldehyde Fixed Paraffin-Embedded (FFPE) ChIP Kit which overcomes the widely acknowledged shortfalls of the technique.
Unlike standard cigarettes, the components of electronic cigarettes are not regulated and standardized, thus they vary widely between products.
A novel investigational West Nile virus vaccine discovered and developed by scientists at the Oregon National Primate Research Center at Oregon Health & Science University is being evaluated in an NIH-sponsored Phase 1, first-in-human, clinical trial at Duke University. Although several early-stage West Nile virus vaccine clinical trials have been completed to date, no human vaccine has been approved for commercial use.
Stem cells naturally cling to feeder cells as they grow in petri dishes. Scientists have thought for years that this attachment occurs because feeder cells serve as a support system, providing stems cells with essential nutrients.
VTT has developed a quick, easy-to-use ketosis test for consumers that can detect acetone on exhaled breath. The test will benefit diabetics and dieters in particular, but it can easily be adapted to other uses as well, such as the detection of the air pollutants formaldehyde or acetaldehyde. VTT is now seeking a partner to commercialise the product.
Dr. Anne Steinemann, Professor of Civil Engineering, and the Chair of Sustainable Cities, from the Department of Infrastructure Engineering, Melbourne School of Engineering, is a world expert on environmental pollutants, air quality, and health effects.
In a study with mice, Johns Hopkins Bloomberg School of Public Health researchers have found that e-cigarettes compromise the immune system in the lungs and generate some of the same potentially dangerous chemicals found in traditional nicotine cigarettes.
Virginia lawmakers will convene in a special session next month to address the question of expanding Medicaid and, more broadly, the fact that hundreds of thousands of poor and disabled people in the state have no health insurance coverage. Democrats and some moderate Republicans have advanced a variety of ideas to tackle that problem. Conservative Republicans, who control the legislature in Richmond, have rejected those solutions while proposing no alternative. Does the GOP intend for the special session to be anything more than a charade at taxpayers' expense? (8/15).
High-voltage electronic cigarettes (e-cigarettes) may expose users to increased levels of toxic chemicals, including formaldehyde and acetaldehyde, according to research led by Maciej Goniewicz, PhD, PharmD, a researcher in the Department of Health Behavior at Roswell Park Cancer Institute (RPCI).
In a first-of-its-kind study, a team of environmental engineers from the Cockrell School of Engineering at The University of Texas at Austin found that infants are exposed to high levels of chemical emissions from crib mattresses while they sleep.
More and more people are developing an itchy, painful rash in an effort to stay clean. A dermatologist at The Ohio State University Wexner Medical Center says a preservative in many types of pre-moistened wipes is linked to a dramatic rise in allergic reactions.
