    Notes: Rotaviruses are nonenveloped viruses that code for two glycoproteins: a structural glycoprotein (VP7) and a nonstructural glycoprotein (NS29). The precursor to VP7 (37K) was shown to contain a 1.5K cleavable signal sequence. The 37K precursor was authentically processed (signal sequence cleaved and the polypeptide “core” glycosylated) when synthesized in a cell-free system supplemented with dog pancreatic microsomes. Similar experiments were performed with the nonstructural glycoprotein precursor (20K); however, the 20K precursor contained an integral (noncleavable) signal sequence. Both precursors were inserted into membranes cotranslationally and both glycosylated products underwent post-translational oligosaccharide processing. The results suggest a morphogenetic scheme for the simian rotavirus SA11.

    Morphological and histochemical organization of the flexor carpi radialis muscle in the cat (1977)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Most studies concerning the structure and function of skeletal muscle have utilized the hind limb of the experimental animal. However, it has been shown that the number of behavioral tasks performed by the cat's forelimb is greater than that of the hind limb. In addition, the forelimb muscles exhibit a functional complexity not observed in hind-limb musculature. The purpose of this study was to investigate the distribution of fast-twitch and slow-twitch muscle fibers and muscle spindles in the flexor carpi radialis muscle (FCR) and to correlate the distributional patterns in these structures with muscle tendon architecture and muscle function. It was found that the FCR, a wrist flexor, contains 37% slow-twitch fibers and 63% fast-twitch fibers. However, the slow-twitch fibers were concentrated in the deep region located between the tendons of origin and insertion, while the fast-twitch-glycolytic fibers were concentrated more peripherally. Muscle spindles were associated with the slow-twitch region and were never found in the region containing high concentrations of fast-twitch-glycolytic fibers. Fast-twitch-oxidative-glycolytic fibers were uniformly distributed throughout the muscle. It is proposed that the association of muscle spindles with slow-twitch fibers and the differential distribution of muscle fibers into slow-twitch and fast-twitch regions might allow these regions to function independently of one another when called upon to perform complex behavioral tasks.
