The aim of this study was to observe autophagy in chondrocytes from degenerative human cervical vertebral end-plates and to investigate the significance of variations in autophagy in the degeneration of cervical vertebral end-plate chondrocytes. Cartilage end-plates were obtained from 48 inpatients admitted to hospital between February 2011 and August 2012. The patients were divided into the co...

This article considers the seismic behavior of beam-to-column joints in steel frames for different bolt arrangements by using of finite element modeling. As the most important beam-to-column joint type, the beam-to-column joints with end-plate is chosen for the analysis. Four different specimens have been analyzed. These models had some differences such as bolt arrangement and the presence or a...

Plant cytokinesis, the final event of cell division, generates two daughter cells by partitioning the cytoplasm of a mother cell. This depends on targeted secretion to generate a new plasma membrane (PM; Whaley and Mollenhauer, 1963; Samuels et al., 1995; Jurgens, 2005a, 2005b). Plant cells control cytokinesis by constructing a plant-specific cytoskeletal configuration, the phragmoplast (Zhang ...

The effects of sodium hydrosulfide (NaHS), the donor of hydrogen sulfide (H2S), on the exo/endocytosis cycle of synaptic vesicles in the motor nerve ending of the mouse diaphragm were studied using intracellular microelectrode technique and fluorescent microscopy. NaHS increased the frequency of miniature end plate potentials (MEPPs), without changing their amplitude–time parameters. NaHS also ...
