Does the heart contain stem cells that are self-renewing?

If you've ever used a loofah in the shower, you've stirred up some stem cells. As the outer layer of skin sloughs off, stem cells in the dermis rush to repair and replace those buffed away.

Good quality of life for cardiogenic shock patients after emergency procedures

Emergency bypass surgery or angioplasty procedures to counteract deadly complications that follow some heart attacks not only improve survival odds for cardiogenic shock patients, but the quality of life after such emergency revascularization procedures appears to be better than that of survivors who received less aggressive treatment, according to a new study in the July 19, 2005, issue of the Journal of the American College of Cardiology.

Engineered tissue is more viable with blood of its own

By adding small blood vessels to artificially grown muscle tissue, the chances of succesful tissue 'repair' rise. Without nourishing blood, thicker tissue has limited viability.

Maintaining a healthy weight in children may be one good way to keep a healthy blood lipid profile and a happy heart

A study of 400 high school age children with a variety of fitness and fatness levels showed that fatter youths had unfavorable lipid profiles, including higher levels of triglycerides and higher ratios of total cholesterol to the protective HDL cholesterol or high density lipoprotein.

Protein found in fat cells is a newly discovered cause of insulin resistance

A study led by researchers at Beth Israel Deaconess Medical Center (BIDMC) has shown that a protein found in fat cells is a newly discovered cause of insulin resistance, establishing a previously unidentified molecular link between obesity and type 2 diabetes and offering a potential new target for the development of drugs to treat diabetes.

Australian stem cell discovery hailed as a major medical and scientific development

Monash Institute of Medical Research (MIMR) senior scientist Dr Caroline Gargett's discovery of adult stem cells in the uterus that can be grown into bone, muscle, fat and cartilage, has been hailed as a major medical and scientific development by international reproduction experts.

Major stem cell discovery

Research published in Nature tomorrow (21 July) will outline for the first time the stem cell origin of the structure of the neck and shoulders in vertebrates.

Metformin should be in the first line of defense against type 2 diabetes

A new review of studies confirms that the drug metformin should be in the first line of defense against type 2 diabetes. Using metformin alone can improve control of blood glucose, while also reducing risk factors for heart disease such as excess body weight, cholesterol levels and hypertension, the review found.

Potential use of NH neurotransmitters as novel source for psychiatric drugs

Physiologists and medical researchers have long recognized the important endocrine roles played by the pituitary hormones oxytocin (OT) and vasopressin (VP) on peripheral systems in lactation, uterine contraction and urine concentration.

New theory on aging says popping pills and drinking orange juice no guarantee you'll live longer

In direct contrast to previous reports, researchers now say that drinking gallons of orange juice and popping vitamin pills may not be a guarantee that you will live longer.

Chemical sealant - poloxamer 188 can repair damage to cardiac muscle cell membrane

A common chemical used in the manufacturing and pharmaceutical industries can repair damage to cardiac muscle cell membranes and prevent heart failure in mice with the genetic mutation that causes Duchenne muscular dystrophy, according to scientists at the University of Michigan Medical School.

Nerve cells can also release neurotransmitters outside of synapses

Every neurobiology textbook invariably states that nerve cells communicate with each other through synapses, the specialized cell-cell contacts found at the end of the cells' threadlike extensions. In the journal Science, researchers at the Salk Institute for Biological Sciences and the University of California at San Diego report that nerve cells, or neurons, may not have to rely on traditionally defined synapses to "talk" to each other.

New molecular insights may one day lead to opportunities to stave off old age

Delving deep into the molecular subtleties of a strain of mice engineered to age rapidly, scientists have found that an accumulation of genetic mutations prompts a cascade of programmed cell death that seems to underpin the aging process.

Scientists have begun to clarify how one of the body's molecules controls the trafficking of T cells through the blood

...lymph nodes and on to tissues to fight infection -- a crucial response that sometimes goes awry, attacking the body's own tissues and causing autoimmune diseases.

Complicated plasminogen system yields potential therapeutic target; Implications for aging and degenerative diseases

Skeletal muscles naturally repair themselves very efficiently after injury. But when they don’t, otherwise successful recovery following damage from overuse during exercise, surgery or trauma can be stymied. Furthermore, as we age, muscle repair slows noticeably, and in Duchenne Muscular Dystrophy and other degenerative muscle diseases, normal repair functions can’t cope with disease progression.

Emergency physicians' fear of malpractice in evaluating patients with possible acute cardiac ischemia

A new survey of emergency physicians finds those most concerned about lawsuits are more likely to admit patients with cardiac symptoms and to order more tests. The results will be published by Annals of Emergency Medicine as an early online release July 13 (Emergency Physicians' Fear of Malpractice In Evaluating Patients With Possible Acute Cardiac Ischemia).

White blood cell called a neutrophil appears to be crucial to abdominal aortic aneurysm formation

Each year, 200,000 Americans find out that the largest blood vessel in their body, the aorta, may burst open at any time. About 20,000 die suddenly from such a rupture. And another 36,000 have surgery to repair or replace the swelling section of aorta before time runs out.

Body mass index proves to be an unexpectedly valuable tool for runners

The conspicuous size differences between beefy sprinters and lithesome distance runners are dictated by simple rules of form and function, according to researchers from Rice University and the Texas Medical Center's National Center for Human Performance.

Outer lining of the umbilical cord is a rich source of stem cells

CellResearch Corporation in Singapore and its team of scientists, headed by Chief Scientist, Dr Phan Toan Thang, have recently made a revolutionary discovery: that the outer lining of the umbilical cord is a rich source of stem cells.
