Stomach ulcer bug causes bad breath
Bacteria that cause stomach ulcers and cancer could also be giving us bad breath, according to research published in the December issue of the Journal of Medical Microbiology. view more (2008-11-24)
Glowing Results-Pitt Researchers Use Fluorescence to Develop Fast, Simple Method for Detecting Mercury in Fish and Dental Fillings
Researchers at the University of Pittsburgh have developed a simple and quick method for detecting mercury in fish and dental samples, two substances at the center of public concern about mercury contamination. view more (2008-11-19)
The risk factors of abdominal venous thrombosis
Abdominal venous thrombosis may present as BCS or SVT. Hereditary and acquired risk factors have been implicated in the etiopathogenesis of abdominal venous thrombosis view more (2008-10-13)
DNA editing tool flips its target
Imagine having to copy an entire book by hand without missing a comma. Our cells face a similar task every time they divide. They must duplicate both their DNA and a subtle pattern of punctuation-like modifications on the DNA known as methylation. view more (2008-09-04)
Anti-Cancer Flower Power
Could a substance from the jasmine flower hold the key to an effective new therapy to treat cancer? view more (2008-08-26)
Mustard - hot stuff for natural pest control
Researchers, growers and Industry specialists from 22 countries will share the latest research into the use of Brassica species, such as mustard, radish, or rapeseed, to manage soil-borne pests and weeds - a technique known as biofumigation. view more (2008-07-28)
'Smothered' genes combine with mutations to yield poor outcome in cancer patients
Johns Hopkins Kimmel Cancer Center researchers have identified a set of genes in breast and colon cancers with a deadly combination of traditional mutations and "smothered" gene activity that may result in poor outcomes for patients. view more (2008-07-16)
Our genome changes over lifetime, Johns Hopkins experts say
Researchers at Johns Hopkins have found that epigenetic marks on DNA-chemical marks other than the DNA sequence-do indeed change over a person's lifetime, and that the degree of change is similar among family members. view more (2008-06-25)
Molecular 'clock' could predict risk for developing breast cancer
A chemical reaction in genes that control breast cancer provides a molecular clock that could one day help researchers more accurately determine a woman's risk for developing breast cancer and provide a new approach for treatment, UT Southwestern Medical Center researchers have found. view more (2008-05-14)
Previously unseen switch regulates breast cancer response to estrogen
A tiny modification called methylation on estrogen receptors prolongs the life of these growth-driving molecules in breast cancer cells, according to research by scientists at Emory University's Winship Cancer Institute. view more (2008-05-09)
Alternatives to ozone-depleting pesticide studied
Methyl bromide, an odorless, colorless gas used as an agricultural pesticide, was introduced in the 1980s as an effective way to control weeds and increase fruit yields. view more (2008-05-08)
Epigenetic research uncovers new targets for modification enzymes
Enzymes regulating genetic expression can be just as important as the genome itself, increasing evidence shows. The expanding field of epigenetics focuses on the multiple influences on DNA and surrounding molecules that determine whether genes are turned on or off during development and disease... view more (2008-04-28)
Mouth may tell the tale of lung damage caused by smoking
Cells lining the mouth reflect the molecular damage that smoking does to the lining of the lungs, researchers at The University of Texas M. D. Anderson Cancer Center report today at the annual meeting of the American Association for Cancer Research. view more (2008-04-14)
Sea salt worsens coastal air pollution: study
Air pollution in the world's busiest ports and shipping regions may be markedly worse than previously suspected, according to a new study showing that industrial and shipping pollution is exacerbated when it combines with sunshine and salty sea air. view more (2008-04-09)
Dental chair a possible source of neurotoxic mercury waste
Mercury is a large component of dental fillings, but it is not believed to pose immediate health risks in that form. When exposed to sulfate-reducing bacteria, however, mercury undergoes a chemical change and becomes methylated, making it a potent, ingestible neurotoxin. view more (2008-03-27)
Scientists unravel the genetic coding of the pea
The pea is one of many important crop species that is unsuited to the Agrobacterium-based genetic modification techniques that are commonly used to work with crops. view more (2008-02-26)
Researchers explore the antidepressant effects of ketamine
Drug treatments for depression can take many weeks for the beneficial effects to emerge. The excruciating and disabling nature of depression highlights the urgency of developing treatments that act more rapidly. view more (2008-02-22)
Paired microbes eliminate methane using sulfur pathway
Anaerobic microbes in the Earth's oceans consume 90 percent of the methane produced by methane hydrates - methane trapped in ice - preventing large amounts of methane from reaching the atmosphere. view more (2008-01-17)
New treatment mechanisms for schizophrenia
The field of schizophrenia research has come alive with many exciting new potential approaches to treatment. From the introduction of chlorpromazine to the current day, all treatments approved by the U.S. Food and Drug Administration have had, at their core, a single treatment mechanism, the... view more (2008-01-09)
The dopamine transporter gene influences alcohol withdrawal seizures
The physiological component of alcoholism is defined by tolerance and/or withdrawal: the more severe the dependency on alcohol, the more severe the clinical complications, such as greater intensity and/or complications of alcohol withdrawal. view more (2008-01-04)
Novel mechanism for long-term learning identified by Carnegie Mellon researchers
Practice makes perfect - or at least that's what we're told as we struggle through endless rounds of multiplication tables, goal kicks and piano scales - and it seems, based on the personal experience of many, to be true. view more (2008-01-04)
'Swish-and-spit' test accurate for cancer
A morning gargle could someday be more than a breath freshener - it could spot head and neck cancer, say scientists at the Johns Hopkins Kimmel Cancer Center. Their new study of a mouth rinse that captures genetic signatures common to the disease holds promise for screening those at high risk,... view more (2008-01-02)
Cough medicine fights dyskinesias in Parkinson's
A cough suppressant and a drug tested as a schizophrenia therapy curb the involuntary movements that are disabling side effects of taking the Parkinson's disease medication levodopa, Portland scientists have found. view more (2007-11-08)
Gene defects could be new cause of male infertility
Scientists at the University of North Carolina at Chapel Hill have identified a gene crucial to the final step of the formation of a functional sperm cell. view more (2007-10-18)
New molecules discovered that block cancer cells from modifying cell DNA
Researchers have discovered new small molecules that may prevent prostate cancer cells from turning off normal genes in a process that transforms normal cells into cancer cells. view more (2007-10-12)
