Early cross-striation formation in twitching Xenopus myocytes in culture.
Spontaneous release of neurotransmitter has been demonstrated in various types of synapses. Its physiological significance, however, is still unknown. In nerve-muscle cultures of embryonic Xenopus laevis, we observed that acetylcholine, which is released spontaneously at the synaptic terminal, caused frequent twitches of muscle cells. These muscle cells developed cross-striations earlier than n...
متن کاملsuppression of coke formation in thermal cracking by coke inhibitors
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولMechanical tension and spontaneous muscle twitching precede the formation of cross-striated muscle in vivo
Muscle forces are produced by repeated stereotypical actomyosin units called sarcomeres. Sarcomeres are chained into linear myofibrils spanning the entire muscle fiber. In mammalian body muscles, myofibrils are aligned laterally, resulting in their typical cross-striated morphology. Despite this detailed textbook knowledge about the adult muscle structure, it is still unclear how cross-striated...
متن کاملStriation Formation and Surface Finish in Laser Cutting of Mild
The mechanisms of melt ejection and striation formation in laser cutting of mild steel are discussed. It is argued that the melt ejection from the cutting front is not a steady state process, but rather shows a cyclic phenomenon. The striation are strongly affected by the unstable characteristic of the thin liquid film on the cutting front during the melt ejection, together with the oxidation a...
