Single particle tracking of internalized metallic nanoparticles reveals heterogeneous directed motion after clathrin dependent endocytosis in mouse chromaffin cells
(IOP Publishing, 2018-01)
Most accepted single particle tracking methods are able to obtain high-resolution trajectories for relatively short periods of time. In this work we apply a straightforward combination of single-particle tracking microscopy ...
Estudo das alterações no potencial de repouso neuronal induzidas por prostaglandina E2 em culturas primárias de gânglio da raiz dorsal de ratos por meio de microscopia de fluorescênciaStudy of changes in neuronal resting potential induced by prostaglandin E2 in primary cultures of the dorsal root ganglia of mice by means of fluorescence microscopy

Progression of Diet-Induced Diabetes in C57BL6J Mice Involves Functional Dissociation of Ca(2+) Channels From Secretory Vesicles
(AMER DIABETES ASSOC, 2010)
OBJECTIVE The aim of the study was to elucidate the cellular mechanism underlying the suppression of glucose-induced insulin secretion in mice fed a high-fat diet (HFD) for 15 weeks. RESEARCH DESIGN AND METHODS-C57BL6J ...
Efeito dos anestésicos gerais inalatórios Sevoflurano e Isoflurano na exocitose de vesículas sinápticas em junção neuromuscular de diafragma de camundongo
(Universidade Federal de Minas GeraisUFMG, 2014-05-28)
Sevoflurane and isoflurane are halogenated anesthetics used for induction and maintenance of anesthesia. Despite being routinely used in clinical practice, their synaptic mechanisms of action are not clearly understood. ...
Sodium-dependent action potentials induced by brevetoxin-3 trigger both IP3 increase and intracellular Ca2+ release in rat skeletal myotubes
(CHURCHILL LIVINGSTONE, 2008-09)
Brevetoxin-3 (PbTx-3), described to increase the open probability of voltage-dependent sodium channels, caused trains of action potentials and fast oscillatory changes in fluorescence intensity of fluo-3-loaded rat skeletal ...
Bothropstoxin-I reduces evoked acetylcholine release from rat motor nerve terminals: Radiochemical and real-time video-microscopy studies
(2013-01-01)
Understanding the biological activity profile of the snake venom components is fundamental for improving the treatment of snakebite envenomings and may also contribute for the development of new potential therapeutic agents. ...

TRP, TRPL and Cacophony Channels Mediate Ca2+ Influx and Exocytosis in Photoreceptors Axons in Drosophila
(2012)
In Drosophila photoreceptors Ca2+-permeable channels TRP and TRPL are the targets of phototransduction, occurring in photosensitive microvilli and mediated by a phospholipase C (PLC) pathway. Using a novel Drosophila brain ...
Modulation of intracellular pH by secretagogues and the Na+/H+ antiporter in cultured bovine chromaffin cells
(1991)
The possible physiological role of cytosolic pH changes in adrenal medullary chromaffin cell secretion was examined by investigating the effects of catecholamine secretagogues on cytosolic pH, which was monitored using the ...
Possible link of different slow calcium signals generated by membrane potential and hormones to differential gene expression in cultured muscle cells
(SOCIEDAD BIOLOGIA CHILE, 2004)
The study of fluorescent calcium signals from cultured rat myotubes has provided interesting results in the past few years. Both K+ depolarization and tetanic electrical stimulation were shown to produce slow Ca2+ signals, ...
