LIGHT DIFFRACTION BY SINGLE STRIATED MUSCLE FIBERSf

Light Diffraction by Single Striated Muscle Fibers

Direct memory access of diffraction patterns from striated muscle--a software view.

Complete software support has been developed for a direct memory access microprocessor system used to store and analyze diffraction data from striated muscle. These studies are based on the premise that the regularly alternating light and dark regions of the fiber behave like a phase grating to incident laser light. A knowledge of the position of a diffracted order can thus be used to determine...

Insight into the actin-myosin motor from x-ray diffraction on muscle.

The origin of reflections in the x-ray diffraction pattern from striated muscle and their use for understanding the structural organization of the contractile machinery are presented and discussed. Results of x-ray diffraction experiments obtained by a number of research groups using a variety of protocols revealed structural changes in contracting muscles which are interpreted in terms of mole...

Effects of Buthus eupeus Venom on Neuromuscular Transmission on Striated Muscle In Vitro

In this study, effects of Buthus eupeus venom on chick biventer cervices nerve-muscle preparation were investigated by twitch tension method. The venom, at 1.3 ?g/ml, increased contractile responses in indirect stimulations. These effects were milder in direct muscle stimulations. It also caused significant enhancement in postjunctional sensitivity as assessed by responses to exogenous acetylch...
