Implanting embryonic cardiac cells prevents arrhythmias

When researchers at Cornell, the University of Bonn and the University of Pittsburgh transplanted living embryonic heart cells into cardiac tissue of mice that had suffered heart attacks, the mice became resistant to cardiac arrhythmias, thereby avoiding one of the most dangerous and fatal consequences of heart attacks.

Life-threatening gene defect related to thoracic aortic disease discovered

A research team led by scientists at The University of Texas Medical School at Houston has identified a defective gene that affects vascular smooth-muscle cells in people who suffer from hereditary thoracic aortic disease, which can kill victims with little warning in the prime of their lives.

Are all heart palpitations dangerous?

Palpitations - the sensation that the heart has started to race or pound, or feels like it has skipped a beat - are usually caused by a harmless hiccup in the heart's rhythm.

Sildenafil increases release of key reproductive hormone oxytocin

Researchers at the University of Wisconsin-Madison report this month that sildenafil increases the amount of oxytocin released by stimulation of the posterior pituitary gland, a small structure directly underneath the brain that regulates hormone levels in response to neural signals.

Four hours in ecomony class doubles the risk for deep vein thrombosis

According to the World Health Organization (WHO) the chances of developing deep vein thrombosis ( DVT) double after traveling for four hours or more; this says WHO equates to one in 6,000 long-haul passengers at risk of potentially dangerous blood clots.

Botox decreases pain and intensity of spasticity following a stroke

Final results from a multi-center study shows that repeated treatments of botulinum toxin type A (BoNTA or Botox?) over one year is well tolerated and results in a significant decrease in spasticity, pain frequency and average pain intensity in upper limbs following stroke, according to research from a neurologist at Wake Forest University Baptist Medical Center.

Identifying cardiorespiratory neurocircuitry involved in central command during exercise in humans

For almost one hundred years the brain's ,central command, system , whose charge includes controlling the body's cardiorespiratory response to exercise , has been pursued. Animal experiments and functional imaging studies have provided clues to the location of this system, but the underlying electrophysiological activity has never been measured.

African Americans may be at higher risk of heart failure because of racial variations in heart muscle's pumping ability

Scientists have known for nearly a decade that African Americans have higher rates of hospitalization for heart failure than other major U.S. racial or ethnic groups, but until now they have had limited information other than socio-economic and demographic characteristics to explain why this is so.
