Distinct ultrastructural differences exist at the neuromuscular junctions of red, white, and intermediate fibers of a mammalian twitch skeletal muscle (albino rat diaphragm). The primary criteria for recognizing the three fiber types are differences in fiber diameter, mitochondrial content, and width of the Z line. In the red fiber the neuromuscular relationship presents the least sarcoplasmic ...

A diet high in fiber (particularly fruit and vegetable fiber) and low in fat and red meat may help to decrease the risk of symptomatic diverticular disease (strength of recommendation [SOR]: C, case-control studies and a large prospective cohort study). For people with diverticular disease, a diet high in fiber might decrease the risk of complications (SOR: C, case series). No studies have eval...

Two trials examined genetic and environmental influences on muscle fiber type proportions. Trial 1 compared Polypay and Coopworth x Polypay male lambs either left intact or castrated early, mid or late in growth. Trial 2 compared Hampshire-sired lambs (females, early castrate wethers and late castrate wethers) from Suffolk x Coopworth dams and whiteface x Coopworth dams. Half the lambs in each ...

Several lines of research have shown that the excitability of the inferior olive is suppressed during different phases of movement. A number of different structures like the cerebral cortex, the red nucleus, and the cerebellum have been suggested as candidate structures for mediating this gating. The inhibition of the responses of the inferior olivary neurons from the red nucleus has been studi...

Collagen plays a vital role in maintaining structural integrity and in determining tissue function. Therefore, methods to detect, quantify, and analyze collagen are valuable. Nevertheless, stains historically employed to detect collagen have disadvantages, principally a poor specificity for thin fibers. Conversely, picrosirius red, which has the capability to detect thin fibers, although freque...

FAULKNER, JOHN A., LEO C.MAXWELL, AND DAVID A. LIEBERMAN. Histochemical characteristics of muscle Jibers from trained and detrained guinea pigs. Am. J. Physiol. 222(4) : 836-840. 1972.~Sixweek-old guinea pigs have nearly 12,000 fibers per plantaris cross section. With aging, some 2,700 fibers were lost. Daily endurance running prevented the loss of fibers and fibers were smaller. Trained animal...

We present an adaptive numerical filter for analyzing fiber-length dependent properties of optical rogue waves, which are highly intense and extremely red-shifted solitons that arise during supercontinuum generation in photonic crystal fiber. We use this filter to study a data set of 1000 simulated supercontinuum pulses, produced from 5 ps pump pulses containing random noise. Optical rogue wave...

The generation and evolution process of red shifting in a ultrafast fiber laser with the soliton self-frequency shift are investigated by numerical simulation. And effect different parameters including pump strength, length dispersion fiber, modulation depth saturable absorber initial field on analyzed for first time to our knowledge. By optimizing these parameters, maximum beyond laser's gain ...
