Herpes Zoster is caused by the Varicella virus, characterized a unilateral vesicular rash, usually restricted to specific dermatome.

An ultrastructural study has been undertaken on the equatorial (sensory) region of the rat muscle spindle. Two kinds of intrafusal muscle fibers, a nuclear bag fiber and a nuclear chain fiber, have been identified in this region on the basis of fiber diameter, nuclear disposition, and M-band appearance. The large-diameter nuclear bag fiber contains an aggregation of tightly packed vesicular nuc...

Aim : to analyze the safety and effectiveness of method cold snaring resection with preliminary hydropreparation when removing superficially colorectal epithelial neoplasms a diameter 5 25 mm. Material methods . The number complications disease recurrence after endoscopic excisions by “cold” mm was assessed. Results Neoplasms were removed in single block 89/122 (72.95 %) cases. 9 100 % cases, 1...

The regulatory mechanisms that control intracellular vesicular trafficking play important roles in cellular function and viability. Neurons have specific vesicular trafficking systems for synaptic vesicle formation, release and recycling. Synaptic vesicular trafficking impairments induce neuronal dysfunction and physiological and behavioral disorders. Parkinson’s disease (PD) is an age-dependen...

The quantal nature of synaptic transmission requires a mechanism to transport neurotransmitter into synaptic vesicles without promoting non-vesicular efflux across the plasma membrane. Indeed, the vesicular transport of most classical transmitters involves a mechanism of H(+) exchange, which restricts flux to acidic membranes such as synaptic vesicles. However, vesicular transport of the princi...

The present work is focused on the preparation of biocompatible silica particles from sodium silicate, stabilized by a vesicular system containing oleic acid (OLA) and its alkaline salt (OLANa). Silica nanoparticles were generated by the partial neutralization of oleic acid (OLA), with the sodium cation present in the aqueous solutions of sodium silicate. At the molar ratio OLA/Na⁺ = 2:1, the m...

The morphological features of pinched-off presynaptic nerve terminals (synaptosomes) from rat brain were examined with electron microscope techniques; in many experiments, an extracellular marked (horseradish peroxidase or colloidal thorium dioxide) was included in the incubation media. When incubated in physiological saline, most terminals appeared approximately spherical, and were filled with...
