Carotid Stenting Not as Effective as Carotid Endarterectomy
15 Feb 01 | Carotid stenting in which a metal mesh tube is inserted into the main neck artery feeding the brain is less effective than surgery as a treatment for carotid blockages that can lead to stroke, a Duke University Medical Center neurologist reported.

Unique Duke Study to Probe how Genetics and Environment Influence Responses to Stress
12 Feb 01 | Being the main caregiver for a spouse suffering from Alzheimer's disease can be a physically and emotionally draining experience -- the slow, unrelenting progression of the disease and its certain outcome put caregivers under constant pressure.

Cognitive Decline After Bypass Surgery Predicts 5-Year Cognitive Decline
08 Feb 01 | While coronary artery bypass graft surgery has saved the lives of millions of Americans since its inception decades ago, physicians have long noticed a nagging problem many patients have noticed declines in their cognitive abilities.

Cell Membrane Plays Crucial Role in Releasing Nitric Oxide from Red Blood Cells
31 Jan 01 | Duke University Medical Center researchers report that the membranes of red blood cells are actively involved in storing and releasing nitric oxide, a molecule that regulates blood flow and oxygen delivery in humans.

Aerobic Exercise Improves Cognitive Functioning of Older Men and Women
16 Jan 01 | The team of Duke researchers who demonstrated that aerobic exercise is just as effective as medication in treating major depression in the middle-aged and elderly has now reported that the same exercise program appears to improve cognitive abilities.

High Mutation Rates in Cancer Cells Can Be Caused By Non-DNA-Damaging Stresses
14 Jan 01 | Duke University Medical Center researchers report for the first time that long-term genetic instability in cancer cells can be induced both by stresses that break DNA and those thought not to damage genetic material.

Duke Cardiologists Improve Outcomes of Angioplasty with Small Doses of Radiation
12 Jan 01 | While the widespread use of tiny flexible tubes called stents has greatly improved the outcomes for heart patients receiving angioplasty, cardiologists still find that the arteries of almost one-quarter of these patients will become clogged again.

Duke Medical Experts Highlight Palm Beach Forum
12 Jan 01 | Physician-scientists from Duke University Medical Center will present the latest in cardiology and genetics, osteoporosis, integrative medicine and other health topics during the 8th annual Duke Palm Beach Forum, Friday, March 2.

Physicians Present Most Comprehensive Clinical Review of St. John's Wort for Treating Depression
09 Jan 01 | Post-holiday blues and a bitter winter season for much of the nation could send many people to the bottle this year -- the bottle of St. John's wort, that is, though many questions remain about its safety and effectiveness, researchers say.

Knight Named CEO for Raleigh Community Hospital
08 Jan 01 | James Knight, who has been responsible for the Duke University Health System's network development programs, has been named the chief executive officer of Raleigh Community Hospital, a component of the Duke Health System.

Switching on Two Genes Activates Significant Regeneration of Spinal Cord Axons
04 Jan 01 | In experiments using cell cultures and gene-altered mice, researchers have found that switching on just two genes can induce considerable regeneration of damaged nerve fibers in the spinal cord.

Imprinted Gene Found on Human Chromosome 19; Mouse Version Involved in Nurturing Behavior
31 Dec 00 | Duke University researchers report that an unusual gene-control mechanism called "imprinting" is at work on human chromosome 19. For imprinted genes, the gene copy that is turned on depends only on whether it came from the mother or father.

Animal Study Shows That Heat-Sensitive Liposome Improves Chemotherapy Delivery to Tumors
15 Dec 00 | A tiny fat-based spherical structure called a liposome, modified at Duke to be sensitive to mild heating, can triple the amount of an anti-cancer drug delivered to tumors in mice compared to other liposome-based drug-delivery methods.

Trying a Long-Distance Approach to Reducing Stress for Lung Transplant Patients
14 Dec 00 | Researchers at Duke University Medical Center believe they can improve the outcomes for lung transplant patients through a systematic program of stress and anxiety reduction before the operation.

Duke Hosts Conference Evaluating Genetic 'Fingerprinting' Methods
12 Dec 00 | Researchers from around the world will gather at Duke University Medical Center to review and critically evaluate available methods for analyzing the large data sets generated from the latest genetic screening technology known as "microarrays."

Gene Initially Implicated in Obesity Appears to Play Role in Immune Responses and Production of Reactive Oxygen species
29 Nov 00 | The group of researchers from Duke University Medical Center and France who found a gene in 1997 that appeared to keep mice from getting obese on a high-fat diet have now identified a new, and possibly more important, role for the gene.

Lung Cancer News Tips from Duke Comprehensive Cancer Center
22 Nov 00 | At the Duke Comprehensive Cancer Center, members of the Thoracic Oncology Program are working to improve the treatment and care of patients with lung cancer, the nation's leading cancer killer in both men and women.

NIDDK Grant Supports Functional Genomics Center
22 Nov 00 | Duke's Center for Genome Technology, one of five centers that make up Duke's brand-new Institute for Genome Science and Policy, has received a grant from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).

New 'Shuttle' Mechanism Discovered by Which Nerve Cells' Connections are Altered
21 Nov 00 | In the process of strengthening or weakening their interconnections, brain cells use a "shuttle" system to increase or decrease the number of receptors for a key signal-transmitting chemical, a Duke University neurobiologist has discovered.

Morris Foundation Commits $2 Million for Prostate Cancer Research at Duke
20 Nov 00 | The Edwin A. Morris Charitable Foundation of Durham and Greensboro has made its largest single gift ever, a $1 million commitment to the Duke Comprehensive Cancer Center.
