DURHAM, N.C. — Despite what you might have heard, genetic sequencing alone is not enough to understand human disease. Researchers at Duke University Medical Center have shown that functional tests are absolutely necessary to understand the biologi…
DURHAM, N.C. — Researchers from Duke University Medical Center have identified how nanoparticles from diesel exhaust damage lung airway cells, a finding that could lead to new therapies for people susceptible to airway disease.
The scientists a…
The best currently available screening tests can only slightly reduce ovarian cancer deaths. That is the conclusion of new research published early online in Cancer, a peer-reviewed journal of the American Cancer Society. The results suggest that st…
DURHAM, NC — Researchers have been stymied for years over the fact that people infected with the AIDS virus do indeed produce antibodies in response to the pathogen — antibodies that turn out to be ineffective in blocking infection.
Now, sci…
DURHAM, N.C. — Pathogenic fungi have been found to protect themselves against unwanted genetic mutations during sexual reproduction, according to researchers at Duke University Medical Center. A gene-silencing pathway protects the fungal genome fr…
ATLANTA, GA — Lupus puts children at higher risk for coronary artery disease when they become adults, but routinely using statins doesn’t provide enough benefit to warrant their regular use in children and adolescents, according to the largest st…
DURHAM, N.C. — Most doctors are spending a good deal of time counseling their patients about diet and weight loss, but for the most part, it isn’t making any difference, according to a new study appearing in the American Journal of Preventive Medi…
DURHAM, N.C. — An international consortium of scientists has discovered new genetic variants in five regions of the genome that affect the risk of ovarian cancer in the general population, according to two separate studies published today (Sunday)…
Biochemists have developed a computational method to design proteins that can specifically detect a wide array of chemicals from TNT to brain chemicals involved in neurological disorders. In a paper in the May 8, 2003, issue of the journal Nature, they demonstrate the breadth of their design method, and also that such sensor proteins can be re-incorporated into cells to activate cellular signaling and genetic pathways.
New research suggests that an overhaul of dietary and fitness habits to help prevent or control high blood pressure is feasible with proper coaching, contrary to the theory that too many changes would be overwhelming and ineffective for most people. The best results in the study were achieved when weight loss, salt restriction and exercise were paired with the DASH (Dietary Approaches to Stop Hypertension) diet, which is rich in fruits, vegetables and low fat dairy products.
Children who receive laboratory-expanded sheets of their own skin to cover severe burns are saved from certain death, but their new skin can have the cellular age of an 80 year old, according to a study at Duke University Medical Center. The process of growing small patches of human skin into larger sheets, called tissue engineering, makes cells divide so many times that the skin becomes prematurely aged at a cellular level.
Researchers at Duke University Medical Center have concluded, in a preliminary study published today, that the drug zonisamide (trade name Zonegran), an anticonvulsant used to treat some types of epileptic seizures, has appetite-reducing effects that could eventually offer hope to thousands of people as an effective therapy for weight loss.
