Secretoma da bactéria fitopatogênica Xanthomonas citri subsp. citri
(Universidade Estadual Paulista (UNESP), 2009-11-05)
O cancro cítrico está entre as principais doenças que afetam a produção de laranjas no Brasil e é causado pela bactéria fitopatogênica gram-negativa Xanthomonas citri subsp. citri (Xac). O presente trabalho teve por objetivo ...
Chemical composition of the dufour gland secretion in queens of Melipona bicolor (Hymenoptera, Meliponini)
We describe differences in the chemical composition of the Dufour gland secretion of virgin and physogastric queens of Melipona bicolor through gas chromatography and mass spectrometry. The Dufour gland secretion of virgin ...
Amphibian secretions for drug discovery studies: A search for new antiparasitic and antifungal compounds
The antiparasitic and antifungal activities of nine amphibian skin secretions were studied in different in vitro models. Seven secretions presented a considerable antiprotozoan activity and one showed promising results ...
Tetracaine stimulates insulin secretion through the mobilization of Ca2+ from thapsigargin- and IP3-insensitive Ca2+ reservoir in pancreatic beta-cells
(Natl Research Council Canada, 2000-06-01)
The effect of tetracaine on Ca-45 efflux, cytoplasmic Ca2+ concentration [Ca2+](i), and insulin secretion in isolated pancreatic islets and beta-cells was studied. In the absence of external Ca2+, tetracaine (0.1-2.0 mM) ...
Chemical composition of precloacal secretions of two Liolaemus fabiani populations: Are they different?
The chemical composition of secretions of precloacal pores from two populations of the lizard Liolaemusfabiani (Puilar and Punta-Brava) were compared. This is an endemic species from the Atacama Salt Flat (26°46'S 68° 14'W; ...
Consuming viscous prey: a novel protein-secreting delivery system in neotropical snail-eating snakes
(Biomed Central Ltd., 2014-03-25)
Background: Efficient venom delivery systems are known to occur only in varanoid lizards and advanced colubroidean snakes among squamate reptiles. Although components of these venomous systems might have been present in a ...
Distribution of non-LEE-encoded type 3 secretion system dependent effectors in enteropathogenic Escherichia coli
(Soc Brasileira Microbiologia, 2014-07-01)
Enteropathogenic Escherichia coli (EPEC) are important human gastroenteritis agents. The prevalence of six non-LEE genes encoding type 3 translocated effectors was investigated. The nleC, cif and nleB genes were more ...
