Synergism between toxin-gamma from Brazilian scorpion Tityus serrulatus and veratridine in chromaffin cells
(Amer Physiological Soc, 1998-06-01)
Toxin-gamma (T gamma) from the Brazilian scorpion Tityus serrulatus venom caused a concentration-and time-dependent increase in the release of norepinephrine and epinephrine from bovine adrenal medullary chromaffin cells. ...
Adverse effects induced by chromium VI, cadmium and arsenic exposure on hypothalamus-pituitary physiology
(Instituto de Histología y Embriología Dr. Mario H. Burgos (IHEM-CONICET), 2016-04)
Environmental contamination with some metalloids and heavy metals (M/HM) raises concern due to well known adverse effects on health. Among these pollutants, chromium VI (Cr VI), cadmium (Cd) and arsenic(As) are frequently ...
Anatomical site of pheromone accumulation and temporal pattern of pheromone emission in the ambrosia beetle Megaplatypus mutatus
(Wiley Blackwell Publishing, Inc, 2011-09)
Megaplatypus mutatus (Chapuis) is a native South American ambrosia beetle that attacks live hardwood trees (e.g. Populus spp.), causing important economic losses to commercial plantations. Male beetles release the main ...
Dehydromonocrotaline induces cyclosporine A-insensitive mitochondrial permeability transition/cytochrome c release
(Pergamon-Elsevier B.V. Ltd, 2009-07-01)
Monocrotaline (MCT) is a pyrrolizidine alkaloid present in plants of the genus Crotalaria that causes cytotoxicity and genotoxicity in animals and humans. It is well established that the toxicity of MCT results from its ...

Fertigation and gradual release of fertilizers for planting of sports turfgrassFertirrigação e fertilizantes de liberação gradual para a implantação de gramado esportivo
(2020-01-01)
Sports turfgrass requires care to show good development and playability. The type of fertilizer and the way of application of this fertilizer directly interfere with its quality. The objective of the present work was to ...
Thyrotropin-releasing hormone as a mediator of the central autonomic pathway controlling ovarian function
(KARGER, 2003-04)
We studied the effect of thyrotropin-releasing hormone (TRH) applied centrally on the sympathetic activity of the ovary in female rats. Intracerebroventricular (i.c.v.) administration of a dose of 25 ng/kg weight produced ...
Host response to Bothrops asper snake venom: analysis of edema formation, inflammatory cells, and cytokine release in a mouse model
(1993)
As part of tle characterization of the host reactivity to the venom of Bothrops
asper, we investigated the inflammatory responses in the mouse footpad model.
The subcutaneously iniected venom induced a rapid increase of ...

Functional gap junctions accumulate at the immunological synapse and contribute to T cell activation
(2011)
Gap junction (GJ) mediates intercellular communication through linked hemichannels from each of two adjacent cells. Using human and mouse models, we show that connexin 43 (Cx43), the main GJ protein in the immune system, ...
