We used double label immunofluorescence and confocal microscopy to examine the organization of beta-spectrin and dystrophin at the sarcolemma of fast twitch myofibers in the Extensor Digitorum Longus (EDL) of the rat. Both beta-spectrin and dystrophin are concentrated in costameres, a rectilinear sarcolemmal array composed of longitudinal strands and ...

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

A previous study has demonstrated the ability to roughly estimate the percentage of fast-twitch muscle fibers for the vastus lateralis through the analysis of peak torque values during fatiguing isokinetic testing. We examined whether use of the hamstrings influenced peak torque and electromyographic (EMG) responses for the quadriceps during fatiguing ...

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

Both adipose tissue and skeletal muscle are highly dynamic tissues and interact at the metabolic and hormonal levels in response to internal and external stress, and they coordinate in maintaining whole-body metabolic homeostasis. In our previous study, we revealed that adipocyte-specific Rnf20 knockout mice (ASKO mice) exhibited lower fat mass but ...

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.

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 ...

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.
