Fragile X-associated tremor/ataxia syndrome difficult to diagnose

Fragile X-associated tremor/ataxia syndrome can be difficult to diagnose and should have guidelines for diagnostic testing, according to a study in the July 26 issue of Neurology, the scientific journal of the American Academy of Neurology. A second study found chemotherapy aggravated symptoms in one woman's case.

Gene that regulates normal embryonic development is found at high levels in virtually all forms of breast cancer

A gene that appears to help regulate normal embryonic development is found at high levels in virtually all forms of breast cancer, according to a new study led by Laszlo Radvanyi, Ph.D., associate professor of breast and melanoma medical oncology at The University of Texas M. D. Anderson Cancer Center.

Stem cell therapy can be used effectively to treat heart attacks, or myocardial infarction, in pigs

In just two months, stem cells harvested from another pig's bone marrow and injected into the animal's damaged heart restored heart function and repaired damaged heart muscle by 50 percent to 75 percent.

Medical scans can trigger airport alarms for up to 30 days after

According to a new study, patients who have had medical scans should be warned that they could set off security alarms at airports for as long as a month afterwards.

Radioisotopes from scans can trigger airport radiation alarms

People having a scan that involves radioisotopes should be warned that they could set off security radiation alarms in airports for up to 30 days after the procedure, state the authors of a case report in this week’s issue of The Lancet.

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.
