Riding roller coasters may actually be 'death-defying' for people with heart disease

...ng episode of atrial fibrillation, a rapid chaotic electrical activity in the upper chambers of the heart. "After the ride stopped, nearly half of the participants had irregular heartbeats or significant sinus arrhythmia, even though their heartbeat rates had returned to normal and were inside the range of a no...

Connective tissue cells from lungs fused with heart muscle to form biological pacemaker

...ther gene, If, which produces proteins involved in electrical signaling, called pacemaker channels. Such channels are protein structures that permit electrical signals, the ions, to pass in and out of cells. Within three minutes of fusion, the cells showed sig...

Squinting while staring at a computer monitor can cause painful dry eye

...d to an electromyogram, a machine that records the electrical activity of muscles. In this case, the researchers wanted to record the action of the orbicularis oculi muscle, which encircles the eye socket and allows the eye to both blink and squint. The electromyogram measured the different degrees of squint. ...

World first trial to test human implant of HeartPOD

...the left atrium, the core body temperature and the electrical conduction of the heart. It is implanted in the patients' left atrial chamber by a cardiac catheterization procedure. The sensor system sends information about the way the heart is working by wireless transmission to a handheld computer, which then a...

Just how these specific glial cells then connect to neurons within the brain to relay information about glucose level, which then prompts glucagon secretion, remains unknown. TITLE: Regulation of glucagon secretion by glucose transporter t...

Mayo Clinic researchers redefining how heart functions

...the body's blood vessels through well synchronized electrical and mechanical waves traveling from the heart's tip (apex) towards the base of the heart." Dr. Belohlavek, a scientist at Mayo Clinic in Rochester, Minn., engaged in more accurately defining how the heart functions, explains, "Relaxation (diastole)...

Sooner is better with cochlear implants, Stanford scientist shows

...r. Their brains learn to understand the artificial electrical stimulation that the implants provide to the cochlea as sound. A Stanford neurobiologist teamed with child-development specialists at the University of Maryland to see if children with cochlear implants were able to meld their newly acquired hearing ...

Inflammation linked to chronic pain: Study

...ainful event, receptors in the injury site send an electrical impulse up the spine and to the brain. The signal triggers receptors called glutamate AMPA and kainate, which flare up initially but do not directly alter the physiology of the cells. When the painful event also triggers inflammation, the nerves send...

How the neuron sprouts its branches

...t functional properties, molecular composition and electrical properties. So, when a cargo reaches a branch point, it's like a highway intersection, and the cargo needs to be directed. We've found that these dendritic Golgi outposts are located at the strategic points to do just that. And I believe this is the ...
