The mechanism involved in the detection of hyperosmolarity by TRP channels is clarified, with a newly discovered molecule preventing apoptosis. A large change in the volume of a cell, from its basal level, is detrimental to its health. Therefore, our cells are equipped with mechanisms to maintain their constant volume. When a cell detects an environmental change that will alter its volume, due to changes in the osmotic pressure, it will adjust its internal water content...

Cardiac Death Controlled By Circadian Clock
2012-02-23 05:49:51

Researchers have discovered a new link between the time of day and sudden cardiac death (SCD). Abnormal heart rhythms are the most common cause of sudden cardiac death, which happens most often in the morning hours, followed by a smaller peak during the evening hours. This phenomenon has been observed for years but doctors are just now beginning to understand the molecular reason. The researchers found that Krupple-like Factor 15 (KLF15) links the body´s circadian rhythm to the...

In two landmark papers in the journal Nature this week, scientists at The Scripps Research Institute report that they have identified a class of proteins that detect "painful touch." Scientists have known that sensory nerves in our skin detect pressure, pain, heat, cold, and other stimuli using specialized "ion channel" proteins in their outer membranes. They have only just begun, however, to identify and characterize the specific proteins involved in each of these sensory pathways. The...

Finnish researchers break ground in neonatal brain research In the past few years, researchers at the University of Helsinki have made several breakthroughs in discovering how the brain of preterm babies work, in developing treatments to protect the brain, and in developing research methods suitable for hospital use. Each year, the brains of hundreds of Finnish children, and therefore their future lives, are at risk due to premature birth or intrapartum asphyxia. The brain is a...

That flutter in your heart may have more to do with the movement of sodium ions than the glance of a certain someone across a crowded room. Using the Canadian Light Source synchrotron, researchers from the University of British Columbia have revealed, for the first time, one of the molecular mechanisms that regulates the beating of heart cells by controlling the movement of sodium in out of the cells — and what calcium has to do with it. The findings, published February 14 in the...

Researchers reveal a novel mechanism through which the brain may become more reluctant to function as we grow older New findings, led by neuroscientists at the University of Bristol and published this week in the journal Neurobiology of Aging, reveal a novel mechanism through which the brain may become more reluctant to function as we grow older. It is not fully understood why the brain's cognitive functions such as memory and speech decline as we age. Although work published this year...

Image 1 - Device Could One Day Read Your Mind By Decoding Brain Waves

[ Watch the Video ] Have you ever imagined taking on the role of Spock in the popular Star Trek shows and films, using your mind melding abilities to read the thoughts of others. Well that could one day become a reality, in a roundabout way. Researchers at the University of California, Berkeley and University of California, San Francisco, have demonstrated a new method to reconstruct words, based on signals from the brains of patients thinking of those words. While it is a far cry from...

Scientists have now discovered how different brain regions cooperate during short-term memory Holding information within one´s memory for a short while is a seemingly simple and everyday task. We use our short-term memory when remembering a new telephone number if there is nothing to write at hand, or to find the beautiful dress inside the store that we were just admiring in the shopping window. Yet, despite the apparent simplicity of these actions, short-term memory is a complex...

Researchers discover dual role of key player in immune system Northwestern University Feinberg School of Medicine researchers have identified a new and unusual role for a key player in the human immune system. A protein initially believed to regulate one routine function within the cell has proven vital for another critical step in the activation of the immune system. That protein, STIM1, was previously known to sense a change in calcium within immune cells, a process that occurs when...

Researchers at the University of California, San Diego School of Medicine have created a new generation of fast-acting fluorescent dyes that optically highlight electrical activity in neuronal membranes. The work is published in this week's online Early Edition of the Proceedings of the National Academy of Sciences. The ability to visualize these small, fast-changing voltage differences between the interior and exterior of neurons — known as transmembrane potential — is...

Electrocardiography
2013-04-30 09:55:53

Electrocardiography, sometimes called ECG or EKG, is a measurement of the electrical activity of the heart as the linear process unfolds. With the use of electrodes that are attached to the skin, this non-invasive test can provide vast information as to the patient’s status. By leaving the electrodes attached, the patient’s status can be monitored over intervals of time and recorded on the device. This data can be sent electronically for consults about potential treatments without delay....

Electrooculography

Electrooculography, sometimes shortened to EOG, is the tracing of electricity used for operation of the retina in different phases, specifically the resting potential. The results are recorded on an electrooculogram. These are interpreted for opthalmological diagnosis and in recording eye movements. Eye movement measurements: Usually, pairs of electrodes are placed either above and below the eye or to the left and right of the eye. If the eye is moved from the center position towards one...
