Phasic transmitter release at synapses in the mammalian CNS is regulated by local [Ca2+] transients, which control the fusion of readily releasable vesicles docked at active zones (AZs) in the presynaptic membrane. The time course and amplitude of these [Ca2+] transients critically determine the time course and amplitude of the release and thus the frequency and amplitude tuning of the synaptic...

To study the cellular mechanisms of efferent actions, we recorded from vestibular-nerve afferents close to the turtle posterior crista while efferent fibers were electrically stimulated. Efferent-mediated responses were obtained from calyx-bearing (CD, calyx and dimorphic) afferents and from bouton (B) afferents distinguished by their neuroepithelial locations into BT units near the torus and B...

The antioxidant bioactivities of the whole isolated anthocyanins from Hibiscus sabdariffa (HS) calyx were evaluated and compared with the bioactivity of vitamin C as a standard water soluble antioxidant vitamin. They were assessed for antioxidant activity based on their ability to impair 2, 4-dinitrophenylhydrazine (DNPH)-induced oxidative tissue damage in toxicant exposed rabbits. Exposure of ...

One of the most important matters in international trades for many local apple industries and auctions is accurate fruit quality classification. Defect recognition a key online computer-assisted sorting machines. Because cavity structure stem calyx regions, system tends to mistakenly treat them as true defects. Furthermore, there no small-scale machine with smart vision classification where it ...

BACKGROUND The specific properties of a synapse determine how neuronal activity evokes neurotransmitter release. Evaluating changes in synaptic properties during sustained activity is essential to understanding how genetic manipulations and neuromodulators regulate neurotransmitter release. Analyses of postsynaptic responses to high-frequency stimulation have provided estimates of the size of t...

A new species, Alysicarpus poklianus Gholami & Pandey from Sinhgarh, Maharashtra, India is described. It is morphologically most similar to Alysicarpus hamosus but differs in having ovate leaves, rounded-ovate bracts, larger size of calyx, pods comprising 5-7 longer than broad joints with easily separable septa. In this study, a comprehensive description, and identification key of Alysicarpus p...

A new species of Vigna Savi, subgenus Ceratotropis (Piper) Verdc., Vignayadavii S.P. Gaikwad, R.D. Gore, S.D. Randive & K.U. Garad, sp. nov. is described and illustrated here. It is morphologically close to Vignadalzelliana (Kuntze) Verdc. but differs in its underground obligate cleistogamous flowers on positively geotropic branches, hairy calyx, small corolla, linear style beak and dimorphic s...

PURPOSE To search the place of non contrast abdominal computed tomography to detect the stone-free rate after percutaneous nephrolithotomy (PNL) and the clinical importance of its superiority against to plain film radiography (KUB). MATERIALS AND METHODS Between February 2006 and July 2010, 62 patients including 27 women had no stone detected peroperative fluoroscopy and nephroscopy during PN...

The nuclei of bovine spermatids and spermatozoa are surrounded by dense cytoplasmic webs sandwiched between the nuclear envelope and the acrosome and plasma membrane, respectively, filling most of the cytoplasmic space of the sperm head. This web contains a complex structure, the perinuclear theca, which is characterized by resistance to extractions in nondenaturing detergents and high salt buf...
