Nitric oxide, a chemical messenger involved in bodily functions shuts down a protein involved in Parkinson's disease

Johns Hopkins researchers have discovered that nitric oxide, a chemical messenger involved in bodily functions from erection to nerves' communication, also shuts down a protein involved in Parkinson's disease.

Scientist discovers why skin turns leathery

“The reason our skin becomes more leathery and thick as we age might be due to a loss of elasticity in the cells,” says Igor Sokolov of Clarkson University, who presented his latest research findings during a session on bio-imaging techniques at the Annual American Physical Society (APS) March meeting in Montreal.

Metabolic syndrome may make arteries thicker and stiffer

A cluster of cardiovascular disease risk factors, known as the metabolic syndrome, may “age” arteries, according to a new study in the April 21, 2004 issue of the Journal of the American College of Cardiology.

New research findings about T-cell transport shed light on immune system

New research findings about T-cell transport shed light on how the normal immune system functions and could have implications in fighting autoimmune and inflammatory diseases, say researchers at University of Texas Southwestern Medical Center, Dallas.

Repeated pregnancies may increase cardiovascular disease

The study was designed to measure the blood pressure responses to phenylephrine and to acute stress in conscious age-matched repeatedly breed (RB) and virgin rats.

Mercy Hospital opens new cardiovascular catheterization laboratory

The $40 million expansion of The Cardiac Centers of Mercy & Unity Hospitals reaches a significant milestone this week with the opening of the most technologically advanced cardiovascular catheterization laboratories in Minnesota.

Leeches back to relieve pain

The leech was indispensable in 19th Century medicine for bloodletting, a practice believed to be a cure for anything from headaches to gout. Leeching was largely abandoned as medical science advanced, only occasionally being called upon to treat bruising and black eyes.

Latest developments in prostate cancer research

New research on genes linked to hereditary prostate cancer helps scientists better understand how prostate cancer grows. Tests to find abnormal prostate cancer genes could also help tell which men are at high risk. They could then be tested more often. Further research could provide answers about the chemical changes that lead to prostate cancer. Then, perhaps, we could design drugs to reverse those changes.

A drug that improves function of retinal blood vessels may be able to reduce the risk of stroke

The small study found that endothelial function is abnormal in eye blood vessels of patients who have early-stage hypertension, but that treatment with an angiotensin-receptor blocker (ARB) drug improves endothelial function. The endothelium is the lining of vessel walls and plays a key role in the vessels’ ability to relax and to constrict.

Cinacalet helps control overactive thyroids, a major complication of advanced kidney disease

A new drug can help control an overactive thyroid, a major complication of advanced kidney disease, by playing a trick on the gland, a new study finds. The drug, cinacalet, is much more effective at keeping the parathyroid gland working normally than a placebo, according to the study. It may be a good alternative to standard therapy, researchers said.

Patients with coronary artery blockages can be treated safely using drug coated stents

The researchers followed 155 consecutive patients treated with multiple sirolimus-eluting stents between April 2002 and March 2003. Each patient had at least two lesions blocking blood flow in different coronary arteries. Earlier studies have demonstrated that patients with a single, simple artery narrowing held open with a sirolimus-eluting stent are less likely to need retreatment than similar patients who received a bare metal stent. However, those studies excluded patients with complex or multiple artery lesions.

Oral sildenafil improved exercise tolerance, cardiac output and quality of life in 22 patients with primary pulmonary hypertension

Oral sildenafil (Viagra®) improved exercise tolerance, cardiac output and quality of life in 22 patients with primary pulmonary hypertension, according to the results of the first randomized, placebo-controlled, double-blind, crossover study, reported in the April 7, 2004 issue of the Journal of the American College of Cardiology.

Fluorescent molecule used to examine real time chemical reactions that result in smooth-muscle contraction

Smooth muscle, found in the walls of blood vessels and in internal organs such as lungs, stomach and the bladder, contracts as the end result of a series of chemical reactions. In a new study, UT Southwestern researchers report that one set of chemical reactions resulting in the contraction of the smooth-muscle cells is augmented by a second chemical pathway that kicks in when the first pathway is limited.

New center enables genetic treatments and advances

A new state-of-the-art research facility dedicated to helping produce modified cells for treatment of cancer and other diseases recently opened at the Siteman Cancer Center.

Natural compound in snake venom for treatment of malignant tumours

Researchers at the University of South Australia have made a major discovery using a natural compound in snake venom that shows very promising anti-cancer effects. The compound works by activating the destruction of cells which make up the blood vessels that supply nutrients to tumours, according to Associate Professor Tony Woods from UniSA’s School of Pharmaceutical, Molecular and Biomedical Sciences.

Novel uses for bacterial cellulose, artificial blood vessels, bioengineered wound dressing

New and unique products created from bacterial cellulose — from electronic paper to treatment for wounds — will highlight a one-day symposium at the 227th national meeting of the American Chemical Society, the world's largest scientific society.

Emerging technologies in tissue engineering and regenerative medicine analysis

Pathbreaking developments in tissue engineering and regenerative therapies are facilitating the design and growth of new organs in labs using biopolymer scaffolds and matrices. Analysis of potential markets for tissue engineering reveals that basic problems such as vascularity must be solved before such implants can gain acceptance as standard treatment methods.

Snake venom launders out all stains

Purveyors of snake oil and its mythical powers may not have had it all wrong, if preliminary findings with the Florida cottonmouth, bloodstains and a washing machine stay on target. An enzyme extracted from the viper's venom appears to help launder out notoriously stubborn blood spots on clothing.

Researchers have successfully grafted human breast tissue into the mammary glands of mice

The last few years have witnessed critical advances in breast cancer therapies. Still, the disease afflicts one in eight American women, and scientists have yet to develop a living model with which they can study the intricacies of human breast-tumor behavior.

Super glue and vascular graft surgery

Got a broken teacup, an art project, or a leaky blood vessel? “Super glue” it. Surgeons at Baylor College of Medicine in Houston are studying whether a liquid sealant, similar to common household “super glue,” forms a tight seal around blood vessels used in vascular graft surgery.
