TORONTO, November 23, 2009 - The time of day matters to forest trees dealing with drought, according to a new paper produced by a research team led by Professor Malcolm Campbell, University of Toronto Scarborough's vice-principal for research and colleagues in the department of cell and systems biology at the St. George campus.
A new study by Mount Sinai researchers has for the first time found that patients with more difficult to treat forms of hepatitis C are half as likely to initiate treatment for the disease, when co
COLD SPRING HARBOR, N.Y. (Mon., Nov. 2, 2009) -- The introduction of high-throughput laboratory methods has greatly increased the pace of research into the genetics of complex diseases.
COLUMBIA, Mo. ¬ -- Pairing a new approach to prepare ancient DNA with a new scientific technique developed specifically to genotype a cow, an MU animal scientist, along with a team of international researchers, created a very accurate and widespread "family tree" for cows and other ruminants, going back as far as 29 million years.
The xenotropic murine leukemia virus-related virus (XMRV) which has previously been linked to prostate cancer has been found to have a dramatically lower prevalence among German prostate cancer patients, if any.
BOSTON -- Although a wide spectrum of human papillomavirus is seen across the population of India, HPV-16 and HPV-18 are the most common types and a vaccination targeting these types could eliminate 75 percent of the cervical cancers in the region, according to data presented at the American Association for Cancer Research Frontiers in Basic Cancer Research Meeting.
A search through decades-old frozen infant stool samples has yielded rich dividends for scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. The team customized a laboratory technique to screen thousands of samples for norovirus, a major cause of acute gastroenteritis outbreaks in people of all ages.
Cytokines are small proteins secreted by cells that serve as molecular messengers between cells. Pro-inflammatory cytokines -- which function in the immune system -- may be involved in alcohol dependence (AD).
- Interaction of gene/gene, gene/environment and environment/environment factors can contribute to alcoholism.
New research looks at the influence of gene/environment interaction on alcoholism among Mexican Americans.
Findings show that interaction between education and a polymorphism of the reward gene contribute to severe alcoholism among Mexican Americans.
More than seventy percent of people who contract Hepatitis C will live with the virus that causes it for the rest of their lives and some will develop serious liver disease including cancer. However, 30 to 40 percent of those infected somehow defeat the infection and get rid of the virus with no treatment.
Previous studies revealed that HBV genotypes as well as mutations in the core promoter, precore or HBx gene have been shown to have an association with the clinical outcome of liver disease, however, this is still controversial. It is likely that this depends on the HBV genotype distribution in certain region.
ROCHESTER, Minn. -- A Mayo Clinic study has found that two genes in mice were associated with good central nervous system repair in multiple sclerosis (MS). These findings give researchers new hope for developing more effective therapies for patients with MS and for predicting MS patients' outcomes.
Bee colonies are well known for high levels of cooperation, but new research published in Molecular Ecology demonstrates a conflict for reproduction between worker bees and their Queens, leading some workers to selfishly exploit the colony for their own needs.
Steep reductions in the abundance of fish, shellfish, and other aquatic fauna in recent centuries are not restricted to animals that live in the sea: historical records show that species in rivers and lakes worldwide also experienced sharp declines.
Patients with a certain genetic variation who received the antiplatelet drug clopidogrel had a decreased platelet response to treatment and among those who had percutaneous coronary intervention (procedures such as balloon angioplasty or stent placement used to open narrowed coronary arteries) had an increased risk of having a cardiovascular event in the following year than patients who did not
