John Hopkins Medicine Find likely to aid drug development Researchers at Johns Hopkins have spotted a strong family trait in two distant relatives: The channels that permit entry of sodium and calcium ions into cells turn out to share similar means for regulating ion intake, they say. Both types of channels are critical to life. Having the right concentrations of sodium and calcium ions in cells enables healthy brain communication, heart contraction and many other processes. The new...

Biotechnology and Biological Sciences Research Council Researchers have uncovered how proteins found in our blood can reduce damage caused to blood vessels as we age, and in conditions such as atherosclerosis and arthritis. Calcification is a major risk factor for heart attack and stroke. Blood vessels can harden as calcium phosphate (CaP) crystals, normally found in bones and teeth, build up in soft tissue as we age or as a result of illness. This can lead to complications in patients...

Leading Parathyroid Expert Babak Larian, MD, FACS Comments on New Study About Vitamin D Supplementation Beverly Hills, CA (PRWEB) May 12, 2014 While there is debate within the medical community in regard to the benefits of vitamin D supplementation, and new research in The Lancet Diabetes & Endocrinology suggests that vitamin D supplements are unlikely to reduce health problems, vitamin D still plays a vital role in proper bodily functions. Dr. Babak Larian of the CENTER for Advanced...

For Simon Gilroy, sometimes seeing is believing. In this case, it was seeing the wave of calcium sweep root-to-shoot in the plants the University of Wisconsin-Madison professor of botany is studying that made him a believer. Gilroy and colleagues, in a March 24, 2014 paper in the Proceedings of the National Academy of Sciences, showed what long had been suspected but long had eluded scientists: that calcium is involved in rapid plant cell communication. It's a finding that has...

Dr. Babak Larian of the CENTER for Advanced Parathyroid Surgery in Beverly Hills comments on new bone health research and parathyroid hormone’s role in healthy bones. Beverly Hills, CA (PRWEB) March 25, 2014 Director of the CENTER for Advanced Parathyroid Surgery in Beverly Hills, Dr. Babak Larian, today responded to new research about bone health. Parathyroid hormone levels influence bone health and ways they contribute to bone conditions, such as osteoporosis. Hyperparathyroidism is...

Using multidisciplinary approach, researchers in Italy and Connecticut provide unprecedented glimpse of what happens to the heart during a heart attack A team of researchers at the University of Florence in Italy and the University of Connecticut Health Center have used a multidisciplinary approach to provide an unprecedented glimpse of what happens to the heart during an "infarction" -- a heart attack -- by looking at how the attack affects electrical activity and calcium release in heart...

Researchers have discovered the fundamental biology of calcium waves in relation to heart arrhythmias. The findings published this month in the January 19 edition of Nature Medicine outlines the discovery of this fundamental physiological process that researchers hope will one day help design molecularly tailored medications that correct the pathophysiology. Heart arrhythmias cause the heart to beat irregularly, resulting in symptoms such as dizziness and fainting, or in severe cases,...

Filtered from a vast sodium sea, more than 1 million calcium ions per second gush through our cells' pores to generate charges Scientists have figured out how calcium channels – the infinitesimal cell membrane pores that generate electrical signals by gating a charged-particle influx – have solved a "needle in a haystack" problem. The solution to the longstanding riddle is reported in the Nov. 24 advanced online edition of Nature by University of Washington and Howard Hughes Medical...

A crucial component of wound healing in many animals, including humans, is the migration of nearby skin cells toward the center of the wound. These cells fill the wound in and help prevent infection while new skin cells regenerate. How do these neighboring skin cells know which way to migrate? What directional cues are they receiving from the wound site? A new paper by Mark Messerli and David Graham of the MBL’s Eugene Bell Center for Regenerative Biology and Tissue Engineering clarifies...

Princeton University researchers have created “souped up” versions of the calcium-sensitive proteins that for the past decade or so have given scientists an unparalleled view and understanding of brain-cell communication. Reported July 18 in the journal Nature Communications, the enhanced proteins developed at Princeton respond more quickly to changes in neuron activity, and can be customized to react to different, faster rates of neuron activity....
