1. Concurrent resting and postural tremors of patients with idiopathic Parkinson's disease were monitored using transducers responding to angular velocity of rotation. Spectra and correlation functions were calculated for each pair of records. 2. When concurrent tremor spectra share indistinguishable fundamental frequencies, have statistically significant peaks in their coherence spectra at tho...

Objective: The aim of this study was to differentiate tremors on the basis of the electromyographic examination. Methods: A total of 100 patients, having different kind of tremors were prospectively analyzed. A detailed neurological and electromyographic examination was performed. The tremor was studied in all limbs positions. Clinically, patients were divided into seven diagnostic groups fulfi...

Deep Slow Slip and Tremors (SSTs) are a combination of transient clusters tectonic tremors slow slip associated with extremely elevated fluid pressures. SSTs thought to reflect transition from viscous brittle plate interface rheology likely exert first-order control on megathrust seismicity. Nevertheless, the deformation mechanisms governing source remain elusive. We herein document occurrence ...

OBJECTIVE To evaluate the cause, frequency and determinants of tremors at secondary care settings. METHODS A hospital based cross-sectional study for seven years (2002-2009) was carried out at Sindh Govt. Hospital (SGH) Liaqatabad No.10, Karachi. Sample size was 403 and sampling technique was Convenience sampling. A data collection form was designed and all essential variables were recorded r...

Patients with nonparkinsonian tremors are the second largest group treated with functional neurosurgery. We summarize the present pathophysiological knowledge of these conditions. Essential tremor (ET) may be due to oscillations within the olivocerebellar circuit. There is experimental evidence from animal models for such a mechanism, and clinical data indicate an abnormal function of the cereb...

Abstract Much effort was taken to elucidate how organic precursors appeared in early Earth, and attention paid two impact experiments: hypervelocity impacts by a propellant gun which simulated meteorite collides Earth forming fatty acids amino from inorganics, micro-impacts planetary ball-mill formed ammonium acetic acid inorganics. Our extended study on showed the formation of carboxylic acids...
