1. Comparison between dexmedetomidine and fentanyl bolus in attenuating the stress response to laryngoscopy and tracheal intubation: a randomized double-blind trial
Abstract Background and objectives: Laryngoscopy and tracheal intubation lead to a sympathoadrenal response. We compared the efficacy of dexmedetomidine with fentanyl bolus to attenuate this response. Methods: One hundred patients admitted for routine surgical procedures under general anesthesia were enrolled in this double blind, randomized, controlled st

2. Characterization of the intestinal graft in a swine hypotensive after brain death model
Abstract Purpose: To establish a hypotensive brain death pig model and observe the effects of hypotension on small bowel donors. Methods: The hypotensive brain death model was produced using the modified intracranial water sac inflation method in ten domestic crossbred pigs. Effects of hypotensive brain death on small bowel tissue morphology were evaluated

3. ENERGY PERFORMANCE IN DISC HARROWING OPERATION IN DIFFERENT GRADIENTS AND GAUGES
ABSTRACT The operational performance of the agricultural tractor can be increased by adjusting parameters such as tire inflation pressure, axle mass distribution and gauge opening, which is a very divergent factor in controlled-traffic production. The objective of the experiment was to measure the energy performance of a 93 kW agricultural tractor in interme

4. Does obesity affect intraocular pressure during laparoscopic surgery?
RESUMO Objetivo: A obesidade é aceita como um fator de risco para a perda visual pós-operatória devido a possíveis elevações perioperatórias da pressão intraocular. Este estudo investigou se as alterações na pressão intraocular diferem de acordo com o índice de massa corporal dos pacientes submetidos à colecistectomia laparoscópica. Métodos:

6. On the stability of internally pressurized thick-walled spherical and cylindrical shells made of functionally graded incompressible hyperelastic material
Abstract In this paper, stability analysis of thick-walled spherical and cylindrical shells made of functionally graded incompressible hyperelastic material subjected to internal pressure is presented. Instability point happens in the inflation of above mentioned shells and in this paper effect of material inhomogeneity and shell thickness has been investig

7. Sex differences on solid organ histological characteristics after brain death1
PURPOSE: To investigate gender differences in the evolution of the inflammatory process in rats subjected to brain death (BD). METHODS: Adult Wistar rats were divided into three groups: female; ovariectomized female; and male rats. BD was induced using intracranial balloon inflation and confirmed by maximal pupil dilatation, apnea, absence of reflex, and

8. High-pressure balloon assessment of pelviureteric junction prior to laparoscopic “vascular hitch”
ABSTRACT Aim To assess if calibration of the ureteropelvic junction (UPJ) using a high-pressure balloon inflated at the UPJ level in patients with suspected crossing vessels (CV) could differentiate between intrinsic and extrinsic stenosis prior to laparoscopic vascular hitch (VH). Materials and Methods We reviewed patients with UPJO diagnosed at childho

9. Numerical Simulation and Experimental Validation of the Inflation Test of Latex Balloons
Abstract Experiments and modeling aimed at assessing the mechanical response of latex balloons in the inflation test are presented. To this end, the hyperelastic Yeoh material model is firstly characterized via tensile test and, then, used to numerically simulate via finite elements the stress-strain evolution during the inflation test. The numerical pressur

10. Mesenteric hypoperfusion and inflammation induced by brain death are not affected by inhibition of the autonomic storm in rats
OBJECTIVES: Brain death is typically followed by autonomic changes that lead to hemodynamic instability, which is likely associated with microcirculatory dysfunction and inflammation. We evaluated the role of the microcirculation in the hemodynamic and inflammatory events that occur after brain death and the effects of autonomic storm inhibition via thoraci

11. The effect of intracuff alkalinized 2% lidocaine on emergence coughing, sore throat, and hoarseness in smokers
OBJECTIVE: We evaluated whether endotracheal tube (ETT) intracuff alkalinized lidocaine was superior to saline in blunting emergence coughing, postoperative sore throat, and hoarseness in smokers. METHODS: In our prospective, double-blind trial, we enrolled 50 smoking patients undergoing surgery under general anesthesia including nitrous oxide (N2O). Patient

12. ANÁLISE DE DESEMPENHO EM TRAÇÃO DE RODADO SIMPLES E DUPLO EM UM TRATOR AGRÍCOLA / ANALYSIS OF TRACTION PERFORMANCE OF SINGLE AND DUAL TIRES IN AN AGRICULTURAL TRACTOR
A major problem of agricultural tractor during several operations in which it is used is the difficulty of working in various moisture conditions and soil types affect your ability to traction force, slip and fuel consumption. What has been observed is that with increased contact surface between the tire of the tractor and the ground, there is the possibilit
