The resting membrane potential and intracellular potassium and sodium concentration of three guinea pig hind limb muscles were studied. These properties are related to the gross color, the speed of contraction, and the biochemically defined fiber type composing the muscle. The resting membrane potential and intracellular content were: white vastus (grossly white, fast-twitch glycolytic) -85.3 m...

This paper presents the fabrication process and operation of a bio-sensor based on tapered optical fiber by using spectrum shift in presence PBS buffer dissolved streptavidin. The taper-fiber sensors are 18 24 μm diameter fabricated use an oxy-butane torch. is obtained broadband light source analyzer (OSA) 40 nm wavelength range. existence streptavidin surface confirmed. experiments have shown ...

The hyperemic response in exercising skeletal muscle is dependent on muscle fiber-type composition and fiber recruitment patterns, but the vascular control mechanisms producing exercise hyperemia in skeletal muscle remain poorly understood. The purpose of this study was to test the hypothesis that arterioles from white, low-oxidative skeletal muscle are less responsive to adenosine-induced dila...

The sudden shift from a commercial energy-rich, fiber-poor diet to natural food is assumed as one of the causes of the low success of gamebird restocking. We fed farmed red-legged partridge (Alectoris rufa) chicks with a diet rich in fiber from their first month of life to the time of their release to assess the possible effects on morphometric characteristics and plasma biochemistry and whethe...

The kinetics of hemoglobin S gelation are critical in sickle disease because microvascular obstruction can be avoided if red blood cells pass these vessels during the delay time, before polymerization and gelation occur in sufficient degree to rigidify the cells. Kinetics, including the delay time and the closely related exponential progress rate, are highly sensitive to hemoglobin concentratio...

The true digestibility of amino acids of 5 groups of different Trifolium varieties and hybrids was established by using the balance method adapted for geese. Digestibility of the most important amino acids Lysine varies from 70.40 (for tetraplod red clover) to 81.78 (for medium leafy white clover varieties); for Methionine from 60.54 (for Trifolium repens f. giganteum) to 89.42 (diploid red clo...

A red-shift optical filter all-optical wavelength converter compatible to all-optical WDM networks is introduced and demonstrated at 40 and 10 Gb/s. The wavelength converter provides reshaping and can act as a power equalizer. We use the device to overcome wavelength blocking in a looped-fiber network demonstration equivalent to 42 cross-connect switches and a 16800 km transmission distance.

background fenton (fe2+ and h2o2) and modified fenton (fe3+ and h2o2) are two popular methods used in advanced oxidation processes (aop) and degradation of persistent organic pollutants (pops), such as dye compounds. in these processes, fe2+ and fe3+ as catalysts and h2o2 as the oxidizing agent are added to the reactor. objectives the aim of the current study is to assess the abovementioned met...

A comparative investigation of the mammalian diaphragm has revealed a correlation between certain cytological aspects of red and white muscle fibers and functional activity. This skeletal muscle presents the advantage of a similar and constant function among the mammals, but its functional activity varies in a quantitative manner. Both the rate of breathing (and hence the rate of contraction of...

PURPOSE To conduct high-resolution imaging of the retinal nerve fiber layer (RNFL) in normal eyes using adaptive optics scanning laser ophthalmoscopy (AO-SLO). METHODS AO-SLO images were obtained in 20 normal eyes at multiple locations in the posterior polar area and a circular path with a 3-4-mm diameter around the optic disc. For each eye, images focused on the RNFL were recorded and a mont...
