Researchers uncover molecular pathway critical to cardiac arrhythmia

University of Maryland School of Medicine researchers have uncovered a previously unknown molecular pathway that is critical to understanding cardiac arrhythmia and other heart muscle problems.

New insights into nephrotic syndrome and high blood pressure

Scientists have now begun to understand kidney damage on a cellular level and how the activity of certain molecules in damaged kidneys contributes to salt and water retention in nephrotic syndrome.

U-M Professor to review data from three prominent studies on heart failure

Roughly 5 million people in the United States live with heart failure, a condition in which the heart is unable to pump blood around the body effectively. The causes and types of heart failure vary greatly, and treatment must be tailored to each patient. In some cases, doctors will prescribe a class of diuretic drugs called aldosterone antagonists.

Individuals without ubiquitin ligase Nedd4L more likely to develop CF

Cystic fibrosis (CF), a chronic disease that clogs the lungs and leads to life-threatening lung infections, is caused by a genetic defect in a chloride channel called cystic fibrosis transmembrane conductase regulator.

UNC researchers develop technique that can observe cellular intricacies of CF

When researchers discovered the primary genetic defect that causes cystic fibrosis (CF) back in 1989, they opened up a new realm of research into treatment and a cure for the disease. Since then, scientists have been able to clone the defective gene and study its effects in animals. Now researchers at the University of North Carolina at Chapel Hill have developed a technique for observing the defects at work in human tissue donated by patients with CF.

High dietary salt intake and obesity together trigger abnormal activation of cellular protein

Dietary salt intake and obesity are two important risk factors in the development of high blood pressure. Each packs its own punch, but when combined, they deliver more damage to the heart and kidneys than the sum of their individual contributions.

Nanion’s automated patch clamp platforms show unparalleled results using stem cell derived cardiomyocytes

The Patchliner and the SyncroPatch 96 have successfully been used for compound analysis under current- and voltage clamp recording conditions using different stem cell-derived cardiomyocytes. The exceptional cell-platform-compatibility and the unique experimental possibilities offered by Nanion’s platforms open up whole new avenues for compound safety testing.

UB transgenic mouse model of Timothy Syndrome improves understanding of autism

The first transgenic mouse model of a rare and severe type of autism called Timothy Syndrome is improving the scientific understanding of autism spectrum disorder in general and may help researchers design more targeted interventions and treatments.

Chronic pain gene discovered

Scientists have found the gene responsible for chronic pain. It said that this could lead to drugs for treating long-lasting back pain.

Researchers describe new function of HCN channels in the heart

The heartbeat is the result of rhythmic contractions of the heart muscle, which are in turn regulated by electrical signals called action potentials. Action potentials result from the controlled flow of ions into heart muscle cells (depolarization) through channels in their membranes, and are followed by a compensating reverse ion current (repolarization), which restores the original state. If the duration of the repolarization phase is not just right, the risk of ventricular arrhythmia and sudden cardiac death increases significantly.

APS sponsors 7th International Symposium on Aldosterone and the ENaC/Degenerin Family of Ion Channels

The American Physiological Society is sponsoring the 7th International Symposium on Aldosterone and the ENaC/Degenerin Family of Ion Channels, being held September 18-22 at the Asilomar Conference Grounds in Pacific Grove, Calif. This scientific conference explores the connection between fluid balance in the body and hypertension, a growing global health concern.

UC Davis computer model can test effects of anti-arrhythmia medications

UC Davis researchers have developed an accurate computer model to test the effects of medications for arrhythmia, or abnormal heart rhythm, before they are used in patients.

Conference to explore new discoveries about origins, diagnosis and treatment of tinnitus

University at Buffalo research showing that a new drug that eliminated tinnitus with a single dose in animal models is among the advances that will be presented at the Fifth Tinnitus Research Initiative Conference, "The Neuroscience of Tinnitus," sponsored by UB's Center for Hearing and Deafness Aug. 19-21 in Grand Island, N.Y.

Vampire bats can smell blood-rich prey: Study

In the labs of University of California, San Francisco and from the wilds of Venezuela scientists have discovered how vampire bats have evolved over the years with a unique weapon that enables them to zero in for a ravenous feed on the warmest blood vessels of their prey.

Conference to focus on connection between fluid balance and hypertension

Each day we consume liquids in order to keep hydrated and maintain our body's fluid balance. But just as a water balloon can get overtaxed by too much liquid, the human body is negatively affected when it retains fluids because it is unable to eliminate them properly. One of the key variables influencing how much fluid we hold in our bodies is ordinary table salt.

Scientists reveal complete three-dimensional atomic structure of an activated GPCR

G protein-coupled receptors (GPCRs) are popular drug targets, accounting for about one-third of approved drugs and many hundreds of drugs currently in development. They act as molecular switches that transduce extracellular signals by activating heterotrimeric G proteins located at the inside of the cell.

Myelin regulates key protein involved in sending long-distance signals

The development of a new cell-culture system that mimics how specific nerve cell fibers in the brain become coated with protective myelin opens up new avenues of research about multiple sclerosis. Initial findings suggest that myelin regulates a key protein involved in sending long-distance signals.

Genetically engineered excitable cells made to generate and pass electrical current

By altering the genetic makeup of normally "unexcitable" cells, Duke University bioengineers have turned them into cells capable of generating and passing electrical current.
