Selective reinnervation of fast-twitch and slow-graded muscle fibers in the toad
Experimental Neurology, 1971The problem of selectivity during reinnervation of skeletal muscles was investigated in the toad. Nerves to the sartorius (homogeneous fast-twitch) and anterior semitendinosus (heterogeneous) muscles were transected and reunited so that each nerve was allowed to reinnervate either muscle. Experiments were performed 5–7 months after operation. Isometric

Velocity of shortening and myosin isozymes in two types of rabbit fast-twitch muscle fibers
American Journal of Physiology-Cell Physiology, 1986The fast-twitch tibialis anterior muscle of the rabbit was stimulated (10 Hz, 8 h/day for 7 wk) to cause complete transformation of the fibers from type IIb to type IIa. The velocity of unloaded shortening of permeabilized single fiber segments dissected from control and chronically stimulated tibialis anterior muscles was measured by the slack test ...

This study was designed to assess the changes in fiber-type distribution of the extensor digitorum longus (EDL) muscle of the mouse during the first 21 days of age following neonatal sciatic neurectomy. Denervated and normal muscles were compared at 7, 14, and 21 days of age and the normal EDL was also studied at 1 day of age.

Size and metabolic properties of fibers in rat fast-twitch muscles after hindlimb suspension
Journal of Applied Physiology, 1987Hindlimb suspension (HS) results in whole muscle atrophic and metabolic changes that vary in magnitude in different hindlimb muscles. The present study was designed to investigate these effects in single fibers. Fiber type and size and the activities of two metabolic marker enzymes were determined in a deep (close to the bone) and a superficial (away ...

Abstract Lactate dehydrogenase activity and LDH isoenzyme distribution were determined in supernatants of skeletal muscles consisting predominately of fast-twitch red, fast-twitch white, or slow-twitch intermediate fibers. The LDH activity was highest in the fast-twitch white.

The aim of the study was to evaluate the possibility to predict the muscle fiber-type proportion in men of different sports specialization by testing the maximal torque production by knee extensors at different velocities. For this reason the proportion of fast- and slow-twitch muscle fibers (MFs) in m. vastus lateralis of 23 athletes (11 endurance and

Indentations in the terminal cisternae were measured in freeze-fracture replicas of extensor digitorum longus (EDL) and soleus muscles from normal rats and from rats in which the spinal cord had been transected at the midthoracic level 6 weeks earlier. The density of indentations was compared with contraction time and characteristics of K-contractures.

Skeletal muscle fibers enzymatically dissociated from adult mouse flexor digitorum brevis muscles were maintained in culture for up to 8 days. After various times in culture, fibers were loaded with fura 2, and Ca2+ transients for trains of 1, 5, and 10 action potentials (100 Hz) triggered by external electrical stimulation were calculated from ...

A time course study was conducted to investigate the possibility of a relationship between fiber degeneration and glycogen depletion in chronically nerve-stimulated extensor digitorum longus muscle of the rabbit. Muscles were stimulated 12 h daily at 10 Hz using alternating one-hour periods of stimulation and rest.

The prognosis for cholangiocarcinoma remains dismal due to a low resection rate and early recurrence. Cancer cachexia is associated with decreased survival and poor quality of life. Herein, we present a rat model of cholangiocarcinoma and demonstrate that thalidomide attenuates tumor growth and improves cachexia.A cholangiocarcinoma model was ...
