Hemodynamic responses to Lachesis muta (South American bushmaster) snake venom in anesthetized rats.

In this work, we examined the hemodynamic responses to Lachesis muta (South American bushmaster) venom in anesthetized male Wistar rats. Venom (1.5 mg/kg, i.

Pharmacological analysis of hemodynamic responses to Lachesis muta (South American bushmaster) snake venom in anesthetized rats.

In this work, we examined some mechanisms involved in the hypotension caused by Lachesis muta (South American bushmaster) venom in anesthetized rats. Venom (1.5 mg/kg, i.

Orbitofrontal sulcal and gyrus pattern in human: an anatomical study.

Unlabelled: The anatomical characterization of the orbitofrontal cortex in human is limited in literature instead of many functional and clinical studies involving it.

Objective: Anatomically define the orbitofrontal region aiming to possible neurosurgical treatments and unify the scientific nomenclature as well.

Method: We analyze eighty four human hemispheres using a surgical microscope.

Strain gauges's analysis on implant-retained prosthesis' cast accuracy.

Introduction: A proper cast is essential for a successful rehabilitation with implant prostheses, in order to produce better structures and induce less strain on the implants.

Aims: The aim of this study was to evaluate the precision of four different mold filling techniques and verify an accurate methodology to evaluate these techniques.

Materials And Methods: A total of 40 casts were obtained from a metallic matrix simulating three unit implant-retained prostheses.

Comparison of the Accuracy of Different Transfer Impression Techniques for Osseointegrated Implants.

The aim of this study was to evaluate 3 transfer techniques used to obtain working casts of implant-supported prostheses through the marginal misfit and strain induced to metallic framework. Thirty working casts were obtained from a metallic master cast, each one containing 2 implant analogs simulating a clinical situation of 3-unit implant-supported fixed prostheses according to the following transfer impression techniques: group A, squared transfers splinted with dental floss and acrylic resin, sectioned, and re-splinted; group B, squared transfers splinted with dental floss and bis-acrylic resin; and group N, squared transfers not splinted. A metallic framework was made for marginal misfit and strain measurements from the metallic master cast.

Rat atrial responses to Bothrops jararacussu (jararacuçu) snake venom.

Envenoming by the pitviper Bothrops jararacussu produces cardiovascular alterations, including coagulopathy, systemic hemorrhage, hypotension, circulatory shock and renal failure. In this work, we examined the activity of this venom in rat isolated right atria. Incubation with venom (0.

Cardiovascular responses to Bothrops alternatus (Urutu) snake venom in anesthetized dogs.

The cardiovascular responses to Bothrops alternatus snake venom in anesthetized dogs were investigated. Venom (0.3 mg/kg, i.

The influence of master cast technique on the cast precision of implant-retained fixed prostheses.

The aim of this study was to evaluate the precision of three different mold filling techniques in order to obtain a cast simulating a three-unit, implant-retained, fixed prosthesis. Thirty casts (n = 10) were obtained using three different mold filling techniques. Group 1 used a unique fulfillment technique, Group 2 used a two-step fulfillment technique, and Group 3 used a latex cylinder technique.
