A basic phospholipase A₂ (LmrTX) isoform was isolated from Lachesis muta rhombeata snake venom and partially characterized. The venom was fractionated by molecular exclusion chromatography in ammonium bicarbonate buffer followed by reverse-phase HPLC on a C-5 Discovery® Bio Wide column. From liquid chromatography-electrospray ionization/mass spectrometry,(More)
A análise de tolueno, benzeno e n-hexano inalterados em urina e sangue humano é uma ferramenta para avaliar a exposição ocupacional a esses solventes. Um método simples usando microextração em fase sólida acoplada ao headspace (HS-SPME), usando fibras de carboxeno/ polidimetilsiloxano (CAR-PDMS) e PDMS, para análise simultânea por cromatografia gasosa de(More)
OBJECTIVE To characterize the relaxation induced by BAY 41-2272 in human ureteral segments. MATERIALS AND METHODS Ureter specimens (n = 17) from multiple organ human deceased donors (mean age 40 ± 3.2 years, male/female ratio 2:1) were used to characterize the relaxing response of BAY 41-2272. Immunohistochemical analysis for endothelial and neuronal(More)
In any study of the effect of malnutrition on the composition of tissues the first problem to be faced is the standard of reference. In the adult organism the deoxyribonucleic acid (DNA) of the nucleus seems to be the least variable of all tissue constituents. The amount of DNA in a cell is related to its genetic make-up, and in a given species seems to be(More)
O tolueno é amplamente usado em aplicações industriais e de laboratório, e está relacionado a problemas de abuso social. O tolueno inalterado em urina é considerado um bioindicador mais específico da exposição ocupacional ao solvente. Entretanto, sua análise apresenta algumas dificuldades de ordem analítica, relacionadas aos baixos valores detectados em(More)
INTRODUCTION MAGP1 is a glycoprotein present in the elastic fibers and is a part of the microfibrils components. MAGP1 interacts with von Willebrand factor and the active form of TGF-β and BMP. In mice lacking MAGP1, thrombus formation is delayed, increasing the occlusion time of carotid artery despite presenting normal blood coagulation in vitro.(More)
We report a rapid purification method using one-step chromatography of SVSP Rhombeobin (LMR-47) from Lachesis muta rhombeata venom and its procoagulant activities and effects on platelet aggregation. The venom was fractionated by a single chromatographic step in RP-HPLC on a C8 Discovery BIO Wide Pore, showing high degree of molecular homogeneity with(More)
