Genes play a role in heart function -- May determine who develops heart failure

...failure, is caused by a weakened heart muscle that prevents it from pumping enough blood. With both types, the body doesn't get enough oxygenated blood to meet its needs. The standard treatments for systolic heart failure include water pills and medications that cause the blood vessels to widen or increase t...

Vitamins C and E support breathing following an operation

...spired that the administration of vitamins C and E prevents many of the problems. After an encouraging experiment with vitamins C and E on an experimental animal, the researchers subjected 34 healthy men to a test. The volunteers received less oxygen than normal for a period of three minutes. Prior to this so...

Memorial Sloan-Kettering scientists uncover function of BRCA2 protein

...be a tumor suppressor -- a protective protein that prevents the development of cancer -- but exactly how the protein does its job was not understood. Now MSKCC scientists have been able to map out the structure of the protein, showing that it interacts directly with DNA and helps to repair genetic damage. An ...

NIAMS scientists find biochemical 'switch' directs muscle building

... It has been known for some time that deacetylase prevents the skeletal muscle gene from being expressed, which inhibits myoblasts from forming muscle. The research team has found that under certain conditions, deacetylase inhibitors (DIs) in myoblasts enhance muscle gene expression an...

Gene found that helps nerve cells survive by preventing cell suicide

...ts, those cells will die. "Hopefully, therapy that prevents cell death by delivering genes like Hsp27 will someday find its way into the clinic," says Woolf. "Patients with Lou Gehrig's disease, for example, suffer a progressive death of their motor neurons leading to paralysis. If Hsp27 were able to prevent ...

Type A and cant handle it?

... researcher. "The Kir6.2 protein senses stress and prevents damage to the heart by helping the cells maintain equilibrium even under peak workloads. Lack of Kir6.2 protein function causes sudden, irreversible damage to heart cells, which could lead to heart failure." In the study, the Mayo Clinic team led by...

Folic acid can help prevent heart disease, strokes University of Ulster research

...ich is found in dairy foods like milk and yoghurt, prevents the build up of homocysteine in people with this genetic make-up. Professor McNulty said: "The evidence appears to suggest that if riboflavin intake is good the genetic predisposition towards elevated homocysteine may be overcome. This is a classic ...

M. D. Anderson breast cancer prevention study reaches three-year mark

Gene therapy success in the laboratory buoys hope for Parkinson's disease

...eatment for late-stage Parkinson's. This treatment prevents overactivity in the substantia nigra. The team, led by Matthew During, M.D., formerly of Jefferson Medical College of Thomas Jefferson University and now at the University of Auckland, decided that instead of turning off the neurons in the subthalami...

Trauma surgeon seeks change in law that discourages counseling of problem drinkers

...s a result, the only effect of the UPPL is that it prevents doctors from identifying alcohol problems in their patients." This hampers their efforts to provide counseling to patients in urgent need of it, Gentilello has learned. "Since patients who do not receive help are twice as likely to be reinjured as pa...

Rigorous, short-term diet-exercise program lowers heart disease risk

...od vessels, thus reducing blood pressure. It also prevents cells in the walls of blood vessels from proliferating and clogging the arteries, a process that contributes to atherosclerosis. Oxidative stress refers to the presence of oxygen free radicals that can attack cells and tissues and contributes to car...

Bacterial protein kills tumors

...e p53 gene, known as a tumor suppressor because it prevents the formation of cancers through a cascade of molecular events that either stops cells from dividing or induces a process called programmed cell death. Normally, the p53 protein is short-lived, surviving just a few minutes in the cell before degradin...

Scripps Research Institute group designs DNA vaccine that inhibits growth of cancerous tumors

...he article, "A DNA vaccine against VEGF receptor 2 prevents effective angiogenesis and inhibits tumor growth" was authored by Andreas G. Niethammer, Rong Xiang, Jurgen C. Becker, Harald Wodrich, Ursula Pertl, Gabriele Karsten, Brian P. Eliceiri, and Ralph A. Reisfeld and appears in the November 4, 2002 online...

U.Va. team identifies gene that could halt spread of cancer

...orescu explained, the cell produces a protein that prevents the cancer cell from invading other organs. U.Va. scientists believe a future diagnostic test for low levels of this protein could be developed. The absence of the protein could serve as a red flag for physicians and help determine which cancers have...

Drug combination opens clogged arteries faster, keeps them open longer

...shown that giving a combination of a new drug that prevents platelets from clumping together, as well as a clot-busting drug, opens up clogged arteries faster and keeps them open longer. The researchers found that giving the anti-clotting drug eptifibatide along with a half-dose tenecteplase (TNK) -- a geneti...

Vaccine shortage study exposes nations 'patchwork' system

...MI An ongoing national shortage of a vaccine that prevents meningitis and pneumonia in children has left doctors scrambling to provide even the minimum number of shots, and has exposed gaps in the nation's "patchwork" vaccine system, the first-ever in-depth study of the problem finds. Three-quarters of 405 d...

Common heart surgery potentially dangerous

...ticoagulant heparin, given during surgery. Heparin prevents clots from forming in the heart-lung machine, which oxygenates and pumps blood for the body while the heart is stopped. Since protamine's approval in the early 1960s, no drug has been approved by the Food and Drug Administration (FDA) to reverse the ...

Investigate the molecular mechanism responsible for higher incidence of prostate cancer for men exposed to pesticides in California. Charact...

Compound developed from mussels may lead to safer, more effective medical implants

... to the surface of the implant, the repellant side prevents the build-up of cells and proteins that typically foul implant devices such as cardiac stents, urinary catheters and dialysis tubing. Such contamination can lead to device malfunction, blood clots or fatal bacterial infections, the researchers say. T...
