Researchers develop new method to track movement of carcinogenic PAHs in the human body

Researchers develop new method to track movement of carcinogenic PAHs in the human body

Researchers for the first time have developed a method to track through the human body the movement of polycyclic aromatic hydrocarbons, or PAHs, as extraordinarily tiny amounts of these potential carcinogens are biologically processed and eliminated. [More]
Resveratrol in red wine may prevent cancer

Resveratrol in red wine may prevent cancer

Alcohol use is a major risk factor for head and neck cancer. But an article published in the November issue of the journal Advances in Experimental Medicine and Biology shows that the chemical resveratrol found in grape skins and in red wine may prevent cancer as well. [More]

Epigem challenges students to come up with solutions to improve quality, safety of milk

Epigem, a high-tech British micro-engineering company, has challenged 15 students from the Durham University-led SOFI CDT (Centre for Doctoral Training in Soft Matter and Functional Interfaces), to come up with solutions to prevent a dangerous carcinogen from contaminating milk. [More]
Scientists discover ways to detect several toxic flame retardants in people's bodies

Scientists discover ways to detect several toxic flame retardants in people's bodies

A new peer-reviewed study found that people are contaminated with several toxic flame retardants rarely studied in the US, including one that has never before been detected in Americans called TCEP. Scientists tested urine samples of California residents for biomarkers of six chemicals, all of which were present. [More]
Genetically diverse mouse model can predict human response to chemical exposures

Genetically diverse mouse model can predict human response to chemical exposures

A genetically diverse mouse model is able to predict the range of response to chemical exposures that might be observed in human populations, researchers from the National Institutes of Health have found. Like humans, each Diversity Outbred mouse is genetically unique, and the extent of genetic variability among these mice is similar to the genetic variation seen among humans. [More]
Hand blenders can emit chlorinated paraffins during normal household use

Hand blenders can emit chlorinated paraffins during normal household use

Eight out of twelve tested models of hand blenders are leaking chlorinated paraffins when used according to the suppliers' instructions. [More]

Routine gasoline spills can potentially impact public health

A new study suggests that drops of fuel spilled at gas stations — which occur frequently with fill-ups — could cumulatively be causing long-term environmental damage to soil and groundwater in residential areas in close proximity to the stations. [More]
Testosterone therapy raises risk of prostate tumors in rats

Testosterone therapy raises risk of prostate tumors in rats

A researcher who found that testosterone raised the risk of prostate tumors and exacerbated the effects of carcinogenic chemical exposure in rats is urging caution in prescribing testosterone therapy to men who have not been diagnosed with hypogonadism, according to a new study published in the Endocrine Society's journal Endocrinology.

Sequencing the Asian liver fluke genome: an interview with Dr Neil Young

Sequencing the Asian liver fluke genome: an interview with Dr Neil Young

Opisthorchis viverrini is a parasitic flatworm (or liver fluke) endemic throughout Thailand, the Lao People’s Democratic Republic, Vietnam and Cambodia. Humans are infected with this parasite when they eat a fluke encysted in inadequately cooked/preserved freshwater fish. [More]
Scientists crack genetic code of liver fluke parasite

Scientists crack genetic code of liver fluke parasite

Singapore-An international team of scientists from Singapore, Thailand, China and Australia has cracked the genetic code of the liver fluke parasite, Opisthorchis viverrini, using a unique DNA analysis technique developed at A*STAR's Genome Institute of Singapore (GIS). [More]
Viewpoints: Va. GOP's 'Medicaid charade'; Paul Ryan's health Rx for poverty; giving the sick unapproved drugs

Viewpoints: Va. GOP's 'Medicaid charade'; Paul Ryan's health Rx for poverty; giving the sick unapproved drugs

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). [More]
Nicotine, cotinine can potentially inhibit DNA damage caused by NNK in tobacco smoke

Nicotine, cotinine can potentially inhibit DNA damage caused by NNK in tobacco smoke

A new in vitro study has revealed that nicotine and cotinine, a metabolite of nicotine, can potentially inhibit DNA damage caused by a certain carcinogen in smoke. [More]
Chemoprevention and colon cancer: an interview with Dr. John Letterio, Case Western Reserve University School of Medicine

Chemoprevention and colon cancer: an interview with Dr. John Letterio, Case Western Reserve University School of Medicine

The basic idea of cancer chemopre­vention is to arrest or reverse the progression of pre­malignant cells towards full malignancy, using physiological mechanisms that do not kill healthy cells. [More]
Research highlights potential cancer risk in non-smokers

Research highlights potential cancer risk in non-smokers

Research led by the University of York has highlighted the potential cancer risk in non-smokers - particularly young children - of tobacco smoke gases and particles deposited to surfaces and dust in the home. [More]
Health concerns over arsenic in rice-especially for children

Health concerns over arsenic in rice-especially for children

Inorganic arsenic in rice and rice-based foods poses health concerns in infants and young children, and steps should be taken to minimize exposure, according to a commentary in the Journal of Pediatric Gastroenterology and Nutrition, official journal of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition.

Mice exposed to low doses of arsenic in drinking water develop lung cancer

Mice exposed to low doses of arsenic in drinking water develop lung cancer

Mice exposed to low doses of arsenic in drinking water, similar to what some people might consume, developed lung cancer, researchers at the National Institutes of Health have found. [More]
Study explores metabolic activities of unique microbes for cleaning environmental contaminants

Study explores metabolic activities of unique microbes for cleaning environmental contaminants

Chlorinated chemicals perform a host of societally useful functions, but they also have a dark side. Once their use life has ended, such agents often become environmental contaminants, sometimes resistant to bioremediation. [More]
Researchers find way to diagnose aggressiveness of oral cancer

Researchers find way to diagnose aggressiveness of oral cancer

Studying mouth cancer in mice, researchers have found a way to predict the aggressiveness of similar tumors in people, an early step toward a diagnostic test that could guide treatment, according to researchers at Washington University School of Medicine in St. Louis. [More]
New vaccine effective at preventing lung cancer in mice

New vaccine effective at preventing lung cancer in mice

Tweaking a protein expressed by most liver cancer cells has enabled scientists to make a vaccine that is exceedingly effective at preventing the disease in mice. [More]
