Genetic finding could lead to targeted therapy for neuroblastoma
Researchers have identified a genetic glitch that could lead to development of neuroblastoma, a deadly form of cancer that typically strikes children under 2. view more (2009-06-25)
A novel method to measure circadian cycles
The variation in individual circadian rhythms is an anecdotal as well as experimentally verified fact. But, until now, to systematically study circadian differences (and thereby hope to rout out the underlying genetic causes), scientists have had to rely on prolonged behavioural observation. view more (2005-09-27)
Genes may make some people more prone to anxiety
Inborn differences may help explain why trauma gives some people bad memories and others the nightmare of post-traumatic stress. Scientists in Germany and the United States have reported evidence linking genes to anxious behavior. The findings appear in the August issue of Behavioral Neuroscience, published by the American Psychological... view more... (2008-08-11)
Scientists find shared genetic link between the dental disease periodontitis and heart attack
The relationship between the dental disease periodontitis and coronary heart disease (CHD) has been known for several years. view more (2009-05-26)
New Study Looks At Sensitivity To Sun
A project designed to try and explain the way genes influence sensitivity to sun is underway at the University of Edinburgh. The study will look not only at the role of ultraviolet radiation in causing skin cancer, but at its benefits in treating of patients with psoriasis, eczema and a range of other skin conditions. Professor of Dermatology... view more... (2002-04-24)
Primary care practitioners need to become genetically literate
Increasing availability of DNA based tests and demand by patients for genetic information and advice mean that primary care practitioners will need to become genetically literate. A paper in this week's BMJ discusses the implications of genetic advances for primary care. Currently, the most important elements for primary care are prediction of... view more... (2001-04-24)
Positioning pelvic cancer patients on stomachs for radiation yields better results
Oregon Health & Science University Cancer Institute researchers have found that positioning pelvic cancer patients on their stomachs rather than their backs is a better method for delivering radiation therapy. view more (2007-10-29)
Estimation of isolation times in the Drosophila simulans complex
The Drosophila simulans species complex continues to serve as an important model system for the study of new species formation. The complex is comprised of the cosmopolitan species, D. simulans, and two island endemics, D. mauritiana and D. sechellia. view more (2008-06-26)
Genetic Testing May Be Valuable in Treating Colorectal Cancer
For the 29,000 patients in the United States with metastatic colorectal cancer, chemotherapy with irinotecan is a standard treatment that has been shown to improve survival. view more (2009-07-28)
Study finds hereditary link to premenstrual depression
A specific genetic variation may be tied to an increased risk for severe premenstrual depression, scientists at the University of North Carolina at Chapel Hill and the National Institute of Mental Health have found. view more (2007-07-18)
Genetic markers identified for alcohol response in UCSF Gallo study
Researchers at the UCSF Ernest Gallo Clinic and Research Center have identified a region on the human genome that appears to determine how strongly drinkers feel the effects of alcohol and thus how prone they are to alcohol abuse. view more (2008-12-10)
Researchers Evaluate Cost-Effectiveness of Genetic Screening to Guide Initial HIV Treatment
A major study from a team of researchers from Weill Cornell Medical College and Massachusetts General Hospital has found that a recent change to HIV-treatment guidelines recommending genetic screening is cost-effective under certain conditions. view more (2008-09-18)
St. Jude shows gene test not needed if cancer drug given in low doses
Investigators at St. Jude Children's Research Hospital have shown that when the cancer drug irinotecan is given in low doses for multiple days, it eliminates the need to delay treatment to perform costly genetic testing that determines if the patient is at risk for serious treatment side effects, such as neutropenia. view more (2007-06-20)
Is there any association between COX2 and colon cancer?
Non-steroidal anti-inflammatory drugs (NSAIDs), which are known to reduce the risk of colon cancer, act directly on cyclooxygenase-2 (COX2) and reduce its activity. view more (2009-05-22)
Coping and copulation behavior may help calculate diabetes risk
Discussion of a man's background, attitude, and sexual history isn't just the fodder of Sex and The City episodes - in the future, it could also be a way of evaluating his risk of diabetes. view more (2008-11-06)
Scientists propose the creation of a new type of seed bank
While an international seed bank in a Norwegian island has been gathering news about its agricultural collection, a group of U.S. scientists has just published an article outlining a different kind of seed bank, one that proposes the gathering of wild species -- at intervals in the future -- effectively capturing evolution in action. view more (2008-10-16)
First molecular evidence of body's internal clock in controlling blood pressure
It has been known for decades that heart attacks and strokes occur most frequently in the early-morning hours. Now, researchers at the University of Pennsylvania School of Medicine have provided the first evidence for the role of our body's internal molecular clock in controlling blood pressure and a mechanism by which this occurs. view more (2007-02-20)
Dog DNA study yields clues to diverse size of breeds
From the smallest Chihuahua to the largest Great Dane, dogs dramatically vary in size, much more than most other animals. Now scientists have discovered a genetic basis for this diversity. view more (2007-04-06)
New technology used to construct the first map of structural variation in the human genome
Beyond the simple stream of one-letter characters in the human genome sequence lies a complex, higher-order code. In order to decipher this level of architecture, scientists have developed powerful new experimental and algorithmic methods to detect copy number variants (CNVs)-defined as large deletions and duplications of DNA segments. view more (2006-11-27)
Ethnic differences in response to HIV medicines
Researchers from the University of Massachusetts and the University of Pennsylvania have shown that race/ethnicity is a predictor of plasma lipids in patients with HIV-1 on HAART (highly active antiretroviral therapy). view more (2006-01-24)
