Synaptic vesicle pool size, release probability and synaptic depression are sensitive to Ca2+ buffering capacity in the developing rat calyx of Held
(Associação Brasileira de Divulgação Científica, 2009)
The calyx of Held, a specialized synaptic terminal in the medial nucleus of the trapezoid body, undergoes a series of changes during postnatal development that prepares this synapse for reliable high frequency firing. These ...
How does the stimulus define exocytosis in adrenal chromaffin cells?
(Springer, 2018-01)
The extent and type of hormones and active peptides secreted by the chromaffin cells of the adrenal medulla have to be adjusted to physiological requirements. The chromaffin cell secretory activity is controlled by the ...
Prospecting for viral natural enemies of the fire ant Solenopsis invicta in Argentina
(Public Library of Science, 2018-02)
Metagenomics and next generation sequencing were employed to discover new virus natural enemies of the fire ant, Solenopsis invicta Buren in its native range (i.e., Formosa, Argentina) with the ultimate goal of testing and ...
Sustained exocytosis after action potential-like stimulation at low frequencies in mouse chromaffin cells depends on a dynamin-dependent fast endocytotic process
(Frontiers Media S.A., 2016-07)
Under basal conditions the action potential firing rate of adrenal chromaffin cells is lower than 0.5 Hz. The maintenance of the secretory response at such frequencies requires a continuous replenishment of releasable ...
Forest recovery of areas deforested by fire increases with elevation in the tropical Andes
(Elsevier Science, 2013-02)
In the tropical Andes, many montane forests have been destroyed, often through human-induced fires. To facilitate the recovery of these forests, it is important to understand the processes that drive secondary succession ...
Riqueza e abundância de espécies em diferentes compartimentos da comunidade vegetal no gradiente fisionômico do Cerrado em Assis, SP
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2012-08-03)
Fire protection has caused ongoing changes in savannas throughout the world, with the expansion of the woody component over more open vegetation. Although these changes have been documented at the landscape level, some ...
Tree carbon stock in evergreen forests of Chiloé, Chile
(Universidad Austral de Chile, Facultad de Ciencias Forestales y Recursos Naturales, 2015)
The carbon stock associated with tree biomass was estimated in evergreen forests near the town of Inío in Chiloé Island, Chile (43º21’ S,
74º07’ W), analyzing its relation with biotic and abiotic properties. A total of ...
