We hypothesized that there are no differences in left ventricular (LV) mechanoenergetics between after hyperpolarized cardioplegic arrest by nicorandil (nicorandil arrest) and after depolarized one by high potassium chloride (KCl arrest). The aim of the present study was to test this hypothesis using LV curved end-systolic pressure-volume relation (ESPVR) and linear pressure-volume area (PVA)-m...

A 54-year-old female patient was presented with upper extremity ischemia. Further investigation revealed ulcerated atherosclerosis plaque in aorta with intramural hematoma and clot formation. The subject underwent a successful surgical resection of mass with the assistance of cardiopulmonary bypass and total circulatory arrest.

AIM (1) To identify risk factors for in-hospital cardiac arrest; (2) to formulate activation criteria to alert a clinical response culminating in attendance by a Medical Emergency Team (MET); (3) to evaluate the sensitivity and specificity of the scoring system. METHODS Quasi-experimental design to determine prevalence of risk factors for cardiac arrest in the hospitalised population. Weighti...

Background: Cardiopulmonary Resuscitation (CPR) is an emergency procedure for the return of spontaneous circulation in patients with cardiac arrest. Many factors can affect success CPR. Objective: This study aims to investigate rate CPR and its related referred Dr. Heshmat Hospital Rasht, Iran. Methods: In this retrospective cohort study, participants were 1008 who had underwent Data collected ...

Abstract Aiming at the emergence of patients with outdoor cardiac arrest, to strive for more golden rescue time, a robot suitable arrest is proposed. Combined medical research on human thorax, dynamic model thorax established, kinematics and dynamics end effector mechanism are analyzed, simulated cardiopulmonary resuscitation in Adams software. The relationship between stroke, speed, accelerati...

Introduction: Considering the high incidence of preterm labor and its known complications, and that human myometrium contains receptors for human chronic gonadotropin (hCG) and that hCG can inhibit myometrial contractions on vitro, made me study treating effects of hCG on preterm labor. This clinical trial study was carried out to compare the effect of hCG, and magnesium sulfate (mgso4) on pre...

This paper examines perceptions of the criminal justice system held by young males using longitudinal survey data from the recent National Longitudinal Survey of Youth 1997 Cohort and the National Youth Survey. First, a model is developed to study how perceptions respond to individual information about the probability of arrest and how perceptions a ect criminal behavior. Then, the model is sho...

Aneurysmal subarachnoid hemorrhage (SAH) is an acute neurologic emergency. We report the case of a 48-year-old male with massive SAH caused by ruptured aneurysm vertebrobasilar transition. During urgent craniotomy, due to re-rupture, adenosine was given for flow arrest but no sinus pause observed. Esmolol administered and strategies cerebral protection were implemented. The surgeon able clip pa...

Background: This study was carried out to evaluate the pattern of reactive oxygen species (ROS) variations during in vitro oocyte maturation and embryo development in sheep, and to investigate whether embryo culture condition and the presence of cell-permeable superoxide dismutase mimetic [Manganese (III) meso-tetrakis (4-benzoic acid) porphyrin (MnTBAP)] can influence ROS pattern. Materials an...
