applied enzyme histochemistry for succinate dehydrogenase (SDH) activity, reflecting oxidative metabolism, in serial sections. Using this approach, they were able to show that 1) motor units are homogeneous in fiber type composition, based on SDH staining; 2) units composed of small SDH-positive fibers or large SDH-negative fibers are both fast-twitch units; but 3) they differ with respect to resistance to fatigue. Units composed of SDH-negative fibers undergo rapid decline in tension following repetitive stimulation, whereas units composed of SDH-positive fi- Downloaded from physrev.physiology.org on March 15, 2012 1448 Physiol Rev • VOL 91 • OCTOBER 2011 • www.prv.org STEFANO SCHIAFFINO AND CARLO REGGIANI proved electrophoretic procedure led to the identification of a distinct type 2D MyHC band (46, 789). The identity of 2X and 2D MyHC was demonstrated by Western blotting (455); however, it was not established whether this MyHC is a different isoform or results from posttranslational modification of other MyHCs until definitive evidence for the presence of a distinct MyHC-2X transcript in type 2X fibers was obtained (184). Motor units composed of type 2X fibers have twitch properties (contraction and half-relaxation time) similar to those of 2A and 2B units, and their resistance to fatigue is intermediate between that of 2A and 2B units (463). In rat skeletal muscle, type 2X fibers have moderate to strong SDH staining (463, 709), and their maximal velocity of…

Sales might be completely isolated from Supply Chain Management, even though M/S sells what SCM procures and produces. Thus, you might conclude that what happens in one functional area is not closely related to what happens in others. As you will learn in this chapter, however, functional areas are interdependent, each requiring data from the others. The better a company can integrate the activities of each functional area, the more successful it will be in today’s highly competitive…

take into account, mainly Bluetooth and WLAN Standards due to their relatively high data rates (for example up to 450 MBit/s for IEEE 802.11 draft n). But even in perfect transmission circumstances, the video data would have to be scaled down, but this would contradict the wish to get the best possible visual impression of the ballast water tank state for the surveyor. Additionally, since the ballast water tanks are made of ship construction steel and very confined, we expect wireless…

parte da palavra são normalmente frafadas em minúsculo, verticais e terminam com ponto. Ex. conc., concentrado. Quando a abreviatura retém a letra final da palavra original, o ponto é omitido. Exemplo em inglês: concn, concentration. Substâncias químicas - elementos químicos são representados por uma ou duas letras no latim, na vertical, sem ponto (a primeira letra é sempre maiúscula e a segunda é sempre minúscula). - SÍMBOLOS E NOMENCLATURA - 5 O ponto é sempre omitido…

difficulty in drawing clear distinctions between physical and chemical resistance factors. Cell wall reinforcement for enhanced leaf toughness results from the deposition of ‘chemicals’, including macromolecules such as lignin, cellulose, suberin, and callose, small organic molecules (e.g., phenolics), and even inorganic silica particles (Schoonhoven et al. 2005). Enhanced synthesis and/or deposition of these chemicals after wounding leads to induced physical resistance (McNaughton and…

characteristics of physical systems. I detail these forces as they relate to the gyromodel in 2.4.6. Life 2012, 2 8 2.1.5. Gyre Summary The prior sections demonstrate that the gyre is a basic and concrete model of broad applicability, a profound heuristic, and an unchanging form that changes. Further, the gyre evidently fulfills many of the modeling requirements of complexity, emergence, chaos, systems, information, and evolutionary theory [44-51]. As such, the burden of…

studies on botanicals, it also may be helpful to consider knowledge of prior human experience and traditional use to choose the end point most relevant to the plant’s use. This will increase the likelihood of obtaining a reproducible and desired clinical end point. Ancient and traditional ethnomedicines are now often modified from “teastyle” consumption (i.e., a diluted form) to concentrates (powders and tablets) by the modern industry. Accompanying claims of safety based on a long…
