arginine vasopressin as a supplementary vasopressor in septic shock restores vascular tone and mean arterial pressure, meanwhile decreases dose and exposure time to catecholamines. the objective of this study was to evaluate the effect of vasopressin on lactate and lactate clearance as markers of tissue perfusion during septic shock. in this prospective, randomized, controlled trial, 30 patient...

introduction: different vasoactive factors can modulate cardiovascular adaptation to hemorrhagic shock including nitric oxide (no). in this study we investigated the effect of  the no synthase inhibitor for treatment of  decompensated hemorrhagic shock in normotensive and hypertensive rats. methods: twenty‑four male wistar rats were divided into two groups: the normotensive and hypertensive gro...

Tungsten and its alloys are considered to be the most nominated plasma-facing materials in fusion reactors, which will exposed enormously rigorous conditions such as thermal load, plasma exposure, neutron radiation. At present, research on behavior of oxide particle-reinforced tungsten-based under long-term steady-state heat load transient shock is insufficient. The purpose this study investiga...

T his paper investigates the movement between stock market bubbles and fluctuations in aggregate variables within a DSGE model for the Iranian economy. We apply a new Keynesian monetary framework with nominal rigidity in wages and prices based on the study by Ikeda (2013), which is developed with appropriate framework for the Iranian economy. We consider central bank behavior differe...

Unsteady dynamic behavior of TTCP model with different wrap around fin sets were investigated in a trisonic wind tunne. The aerodynamic coefficient force measurement in this wind tunnel shows good agreement in comparison with that of the NASA Langley Research Center in static case. The model was sinusoidally oscillated at three different frequencies of 1, 3 and 8 Hz at M=2.0 and the effects of ...

Aluminium phosphide (AlP) is used to kill rodents in grain storage. It produces phosphine gas which is toxic for mitochondria. The exact mechanism of action is unclear, but phosphine is thought to produce toxicity by blocking cytochrome-c oxidase, which inhibits oxidative phosphorylation and result in cell death. This poisoning has a high mortality, and survival is unlikely if more than 1.5 g i...

Investigations of flutter in transonic turbine cascades have shown that the movement of unsteady normal shocks has an important effect on the excitation of blades. In order to predict this phenomenon correctly, detailed studies concerning the response of unsteady blade pressures versus different parameters of an oscillating shock wave should be performed, if possible isolated from other flow ef...
