We have shown previously that the regulatory subunit (RII) of a type II cAMP-dependent protein kinase is an integral component of the mammalian sperm flagellum (Horowitz, J.A., H. Toeg, and G.A. Orr. 1984. J. Biol. Chem. 259:832-838; Horowitz, J.A., W. Wasco, M. Leiser, and G.A. Orr. 1988. J. Biol. Chem. 263:2098-2104). The subcellular localization of this flagellum-associated RII in bovine cau...

Plant-derived natural fibers have recently been used as a promising reinforcement in polymer matrix composites. Fibers from the inner sponge of luffa cylindrica fruit subject several studies various resins. However, no research has done on Sponge Gourd Outer Skin Fiber (SGOSF). The present work is aimed to extract and characterize chemical physical properties novel lignocellulosic fiber obtaine...

The features and mechanisms of the processes occurring during concrete centrifugation are considered. It was found that a significant difference in centrifugal centripetal forces acting on outer, middle inner layers cross-section leads to differences structure characteristics element layers. possibility regulating variatropia controlling properties seal by prescription factors is forms various ...

Galanin-like peptide (GALP) is a novel galanin-like peptide isolated from the porcine hypothalamus. To determine the distribution of GALP in the rat brain, we performed immunohistochemical studies using a monoclonal antibody toward the N-terminal sequence of GALP. GALP-immunoreactive neuronal cell bodies were observed only in the arcuate nucleus (Arc), which was further confirmed by in situ hyb...

The interfibrillar spaces of skeletal muscle fibers in adult vertebrates contain two distinct membranous systems, the T system and the sarcoplasmic reticulum. Most of the T system is oriented transversely between the fibrils. Occasionally, longitudinal connections between the transversely oriented T system are seen (14). The sarcoplasmic reticulum is, in general, oriented longitudinally between...

In this work, the interactions between tungsten (W) and silicon carbide (SiC) in Sigma SiC fibers at high temperatures were characterized using scanning and transmission electron microscopy. These fibers could have the potential for use in fusion-related applications owing to their high thermal conductivity compared with pure SiC-based fibers. The as-received fibers were composed of a 100-μm-th...

A significant problem associated with asphalt concrete mixtures is the lack of durability resulting from an inadequate asphalt cement content. Additional asphalt cement added to increase durability results in flushing, bleeding and a significant loss In stability. Fibers have been used in stone matrix asphalt and open-graded friction course pavements successfully throughout Europe to allow high...

Understanding the innervation of the lumbar spine can be a daunting task. Until recently, only macroscopic visualization and crude histological techniques were available to document the presence of nerve fibers in the anterior spinal canal. Using newer immunohistochemical techniques, studies have been able to more thoroughly investigate the innervation of the anterior spinal canal. The presence...
