Backache beaten by good vibrations?

...ns: "Sciatica is an extremely common and disabling condition treated by physiotherapists. "The pain caused by inflammation of lumbar nerve roots could potentially be reduced with the application of TU, a form of electrotherapy commonly used by physiotherapists to accelerate the resolution of the inflammator...

...ces, such as computers. The research focuses on a condition called the completely locked-in state (CLIS, a total lack of muscle control). In a CLIS situation, intentional thoughts and imagery can rarely be acted upon physically and, therefore, are rarely followed by a stimulus. The research suggests that as t...

How fish mend a broken heart

...that the capacity for regeneration is an ancestral condition that has occasionally been lost in the course of vertebrate evolution." Poss said. "Thus, most biologists suspect that the machinery to optimize regeneration from progenitor cells is present, but lies dormant, in mammals." In an earlier study, Poss...

Gene key to taste bud development identified

...tations can develop a tracheoesophageal fistula, a condition in which there is an abnormal connection between the windpipe and throat that requires surgery for correction. Cancer patients receiving chemotherapy or radiation therapy often report the loss of taste during treatments. These therapies target cell...

Mechanical 'artificial hearts' can remove need for heart transplant by returning heart to normal

...ssed by the dramatic, sustained improvement in the condition of these severely ill patients and we believe that this is due to the additive effects of the particular combination therapy used. The improvement observed was far greater than what has been reported to date for any other therapy in patients with sev...

Stem cell therapy shows promise in regenerating damaged muscle in heart attack patients

... Provacel experienced improvement in their overall condition at six months as compared to those receiving placebo (42% vs. 11%, p=0.027). Provacel is a preparation of adult stem cells pre-formulated for intravenous delivery by the drug's manufacture, Osiris Therapeutics. Patients were administered an infus...

Sleep enforces the temporal sequence in memory

...other. Afterwards they slept, whereas in a control condition no sleep was allowed. Later, recall was tested by presenting one word and asking which one came before and which one came after during learning. Sleep was found to enhance word recall, but only when the students were asked to reproduce the learned wo...

Einstein's tea leaves inspire new blood separation technique

...ase remains stationary. To satisfy a zero-velocity condition at the base, an inward force near the bottom of the liquid is generated, suppressing the centrifugal force there. Thus the microscopic particles spiral inward toward the bottom of the chamber like a miniature tornado, leaving a clear layer of plasma ...
