myocardial performance, utilizing the isolated canine heart preparation, was studied in two groups: normal control dogs and those subjected to hemorrhagic shock. a marked deterioration in myocardial functional capacity was observed in the shock group. from this study, myocardial incapacity resulting from the period of acute hypotension is felt to be a contributing factor in the death of animals...

abstract background: many people suffer from burn injuries every year, and burns make the patients undergo surgeries and years of rehabilitation. burns lead to more years of disability, compared to cancer or heart diseases. epidemiologic studies are needed to reveal the span, impact, and related factors of burns to help take appropriate efforts to reduce its mortality and morbidity. materials a...

trauma is the most common cause of mortality and morbidity in pediatric population. caring for the injured child requires special knowledge, precise management, and scrupulous attention to details. all clinicians who are responsible for the care of a pediatric trauma patient, including pediatricians, pediatric emergency room clinicians, and trauma surgeons, must be familiar with every tenet of ...

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...

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...

cacl2 treatment followed by heat shock is the most common method for artificial transformation. here, the cells were transformed using cacl2 treatment either with heat shock (standard protocol) or without heat shock (lab protocol) to comprehend the difference in transformation efficiency. the bl21 strain of escherichia coli (e. coli) was being susceptible using cacl2 treatment. some cells were ...
