A step toward tissue-engineered heart structures for children
Infants and children receiving artificial heart-valve replacements face several repeat operations as they grow, since the replacements become too small and must be traded for bigger ones. Researchers at Children's Hospital Boston have now developed a solution: living, growing valves created in the lab from a patient's own cells. view more (2007-09-13)
Safety, efficacy of corneal transplant procedure confirmed; an antibiotic can cause double vision
Highlights of September's Ophthalmology, the journal of the American Academy of Ophthalmology (Academy), include a 2009 review by the Academy of the safety and efficacy of a widely used corneal transplant procedure and a warning about an unusual but serious reaction to systemic fluroquinolones, a class of antibiotics used to treat a variety of... view more...

Transplanted fat cells restore function after spinal cord injury
A study published in the current issue of CELL TRANSPLANTATION (Vol.17, No. 8) suggests that mature adipocytes - fat cells - could become a source for cell replacement therapy to treat central nervous system disorders. view more (2008-12-11)
Cancer drugs my build and not tear down blood vessels
Scientists have thought that one way to foil a tumor from generating blood vessels to feed its growth - a process called angiogenesis - was by creating drugs aimed at stopping a key vessel growth-promoting protein. But now the opposite seems to be true. view more (2008-11-10)
Discovery of cardiac stem cells may advance regenerative heart therapy
An immediate early publication of the journal Cell, published by Cell Press, on Nov. 22, 2006 points to the possible existence of master cardiac stem cells with the capacity to produce all three major tissues of the mammalian heart. view more (2006-11-27)
Study helps explain origins of cardiac fibrosis in patients with heart disease
A report led by researchers at Beth Israel Deaconess Medical Center (BIDMC) helps explain the origins of cardiac fibrosis, a stiffening of the heart muscle that leads to a variety of cardiac diseases, most notably heart failure. view more (2007-07-30)
Diabetes Risk Factors Develop Earlier in Women than Men
The "diabetes clock" may start ticking in women years in advance of a medical diagnosis of the disease, new research has shown view more (2007-02-21)
Study: Women with hard to diagnose chest pain symptoms at higher risk for cardiovascular events
Many physicians are presented with the following scenario: a woman comes into the office complaining of chest pain, undergoes a stress test to evaluate the chest pain, and the stress test results suggest coronary artery disease, a condition in which plaque builds up inside the coronary arteries. view more (2009-05-12)
Bristol Scientists Discover New Molecule That Could Prevent Tumour Growth
Scientists at Bristol University have discovered a new molecule that could prevent tumour growth. Dr Dave Bates and Dr Steve Harper in the Microvascular Research Laboratories in the Department of Physiology, working in collaboration with clinicians at Southmead Hospital, have discovered a type of vascular endothelial growth factor (VEGF) found in... view more...

Magnetic nano-'shepherds' organize cells
The power of magnetism may address a major problem facing bioengineers as they try to create new tissue -- getting human cells to not only form structures, but to stimulate the growth of blood vessels to nourish that growth. view more (2009-04-01)
Nocturnal dialysis improves heart disease in patients with end-stage kidney failure
Night-time hemodialysis patients may have a greater capacity to repair their hearts and blood vessels compared to those on conventional dialysis three times a week. view more (2005-10-03)
New source of heart stem cells discovered
Researchers at Children's Hospital Boston are continuing to document the heart's earliest origins. Now, they have pinpointed a new, previously unrecognized group of stem cells that give rise to cardiomyocytes, or heart muscle cells. view more (2008-06-23)
Pittsburgh scientists identify human source of stem cells with potential to repair muscle
For the first time, scientists at Children's Hospital of Pittsburgh of UPMC have discovered a unique population of adult stem cells derived from human muscle that could be used to treat muscle injuries and diseases such as heart attack and muscular dystrophy. view more (2007-09-05)
Study reveals how blood flow force prevents clogged arteries
Machines on cell surfaces, mechanical and lifeless as bed springs, protect blood vessels by responding to blood flow force, according to research published today in the Journal of Cell Biology. view more (2008-08-26)
Genetic factors may predict depression in heart disease patients
Individuals with heart disease are twice as likely to suffer from depression as the general population, an association the medical community has largely been unable to explain. view more (2009-05-20)
Researchers warn milk eliminates cardiovascular health benefits of tea
Research published on-line (Tuesday 9 January) in European Heart Journal[1] has found that the protective effect that tea has on the cardiovascular system is totally wiped out by adding milk. view more (2007-01-09)

Researchers Find New Class of Nontoxic Cancer Treatments
A new class of compounds developed by two University of Kentucky researchers shows promise as a nontoxic treatment of some cancers previously treated with toxic chemotherapy, the researchers report today. view more (2007-05-02)
Researchers identify how binge drinking may drive heart disease
As the holidays arrive, a group of researchers has identified the precise mechanisms by which binge drinking contributes to clogs in arteries that lead to heart attack and stroke, according to a study published today in the journal Atherosclerosis. view more (2008-11-26)
Stem cell therapy may offer hope for acute lung injury
Researchers at the University of Illinois at Chicago College of Medicine have shown that adult stem cells from bone marrow can prevent acute lung injury in a mouse model of the disease. view more (2009-10-29)
