Research raises question on shark cartilage use as an anti-cancer treatment

The rising popularity of shark cartilage extract as an anti-cancer treatment is a triumph of marketing and pseudoscience over reason, with a tragic fallout for both sharks and humans, according to a Johns Hopkins biologist writing in the Dec. 1 issue of Cancer Research.

A vitamin B pill that drastically lowers blood levels of homocysteine could one day be used to prevent dementia

High blood levels of homocysteine are a risk factor for stroke and dementia, including Alzheimer’s disease. Raised levels damage nerves and blood vessels, and lead to a loss of brain tissue in patients.

New possibilities for the use of VEGF in the treatment of Amyotrophic Lateral Sclerosis

ALS is an incurable, paralyzing neurodegenerative disorder that strikes 5 persons in every 100,000. The disease commonly affects healthy people in the most active period of their lives − without warning or previous family history.

Bypass surgery on a beating heart is an excellent option for many patients with blocked heart arteries

Bypass surgery on a beating heart is an excellent option for many patients with blocked heart arteries, according to a study in Circulation: Journal of the American Heart Association.

More muscle facilitates the ability to regulate blood pressure

People with more muscle than fat have increased ability to regulate their blood pressure in response to stress, according to a Medical College of Georgia study.

Overexpression of a protein called Down Syndrome Critical Region 1 (DSCR-1) reduces tumor growth

Scientists have found that overexpression of a protein called Down Syndrome Critical Region 1 (DSCR-1) blocks the formation of new blood vessels and thus reduces tumor growth. Therapeutics based on this finding may potentially lead to new cancer treatments.

Unusual protein pair that stops blood vessels' growth in the developing back

In experiments with mice, a research team led by Johns Hopkins scientists has discovered an unusual protein pair that stops blood vessels' growth in the developing back.

Research provides more evidence of communication between developing nerves and blood vessels

In a developing embryo, the growth of nerves cannot outpace the establishment of life-giving blood vessels. Now, researchers have found that a protein intimately involved in blood vessel patterning actually belongs to a family of proteins known to guide neural development.

Keeping fit lowers C-Reactive protein in people with metabolic syndrome

In people with signs of metabolic syndrome, including high blood pressure, high triglycerides, high cholesterol, elevated blood glucose and obesity, physical activity appears to reduce a marker for inflammation which has been linked to heart disease

Fluorescent protein tool may speed identification of molecular changes that reveal cells' inner workings

Scientists at Johns Hopkins and the University of Texas Medical Branch have created a new tool that easily reveals when and where a key cellular signal is active.

Heart bypass gets new source for replacement blood vessels

The search for a stable, renewable source of blood vessels, especially for potential use in heart bypass surgery, has reached a milestone at the State University of New York at Buffalo.

Sirolimus drug-coated stent causes less inflammation than bare metal stents

In the treatment of coronary artery disease, a sirolimus drug-coated stent causes less inflammation than bare metal stents, according to preliminary research presented at the American Heart Association annual meeting by Loyola University Health System, Maywood, Ill.

Patients with type 2 diabetes and hypertension who kept their blood pressure very tightly controlled had fewer eye disorders caused by their diabetes

According to the article, type 2 diabetes and hypertension are often associated. At age 40, approximately 32 percent of patients with type 2 diabetes are also hypertensive, and that proportion increases to 47 percent by age 60, the article states.

MRI technique for measuring blood volume helps distinguish between abscesses and tumors in the brain

Dynamic susceptibility contrast (DSC) MRI allows physicians to differentiate between cerebral abscesses—inflamed areas in the brain caused by infection—and malignant brain tumors without surgery, says a new preliminary study by researchers from Duke University Medical Center in Durham, NC.

Doctors must choose and manage implanted cardiac defibrillators patients carefully

Implanted devices that can shock a failing heart back into regular rhythm do an excellent job of keeping patients alive, two new University of Michigan studies find.

Association between long-term air pollution exposure and the early stages of atherosclerosis

Air pollution may trigger and accelerate narrowing of carotid arteries, according to a study presented at the American Heart Association's Scientific Sessions 2004.

Researchers have identified a protein that transports the essential nutrient boron into cells

Researchers at UT Southwestern Medical Center at Dallas have identified a protein that transports the essential nutrient boron into cells, where it is important for cell growth and bone development. The findings are in the Nov. 5 edition of the journal Molecular Cell and are online.

Celebrex may one day be used to prevent and even treat breast tumors

The anti-inflammatory drug Celebrex, or celecoxib, reduces tumor mass by encouraging cell death and discouraging both cell proliferation and the sprouting of new blood vessels that feed growing tumors, according to a study reported in the November issue of Molecular Cancer Research.

Discovery of internal molecular clock that governs the metabolism of sugars and fats within the body

Researchers at the University of Pennsylvania School of Medicine have discovered that components of the internal molecular clock of mammals have an important role in governing the metabolism of sugars and fats within the body.
