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.

Children with sickle cell disease are living longer, dying less often from their disease

Children with sickle cell disease, an inherited red blood-cell disorder, are living longer, dying less often from their disease and contracting fewer fatal infections than ever before, researchers at UT Southwestern Medical Center at Dallas report. Their study, which will appear in the June edition of the scientific journal Blood, is the first to evaluate survival rates of children receiving the most modern treatments for sickle cell disease. It's also one of the largest published sickle cell studies to date. Researchers followed more than 700 Dallas-area children with the disease over two decades.

Stenting for Stroke Prevention is More Effective Than Surgery in Keeping Blood Vessels Open

Research presented in a six-hour symposium on carotid artery disease at the 29th Annual Scientific Meeting of the Society of Interventional Radiology showed carotid artery stenting to be safe and effective for highrisk patients. Currently, the standard of care for stroke prevention in patients with moderate to severely blocked carotid arteries is carotid endarterectomy surgery. The ARCHeR trials treated patients who were high-risk surgical candidates with carotid artery stenting with and without embolic protection, a device to capture debris that may break off during the procedure.

New Research Information on Tumor Necrosis Therapy

Researchers for Peregrine Pharmaceuticals presented today at the Strategic Research Institute’s Clinical-Stage Product Partnering Summit in La Jolla, CA a summary of clinical experience with Tumor Necrosis Therapy (TNT). The TNT technology is being developed in the U.S. and Europe by Peregrine under the trade name Cotara™. Over 200 patients have been treated with TNT world-wide and a TNT product has been approved to treat grade III or IV advanced lung cancer in the People’s Republic of China. A Cotara registration study for brain cancer has been approved by the U.S. Food and Drug Administration, and a Phase I colorectal cancer study is on-going at Stanford University Medical Center.

Risk Assessment of Diabetic Retiopathy Improved by Screening Methods

Eli Lilly and Company as part of a continued commitment to innovation in the area of diabetes, announced today the creation of a strategic relationship with EyeTel Imaging, Inc. to improve screening and detection of diabetic retinopathy, one of the potentially devastating diabetic microvascular complications. The agreement, which expands the relationship between the two companies, will provide EyeTel with on-going operational support from Lilly, allowing EyeTel to provide primary care physicians access to state-of-the-art patient risk assessment tools and education programs.

New research may help treatment of Norrie disease and familial exudative vitreoretinopathy (FEVR)

Researchers have discovered that genetic mutations underlying two inherited eye disorders arise in different components of a single intracellular signaling pathway that is responsible for development of blood vessels in the eye.
