objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
The relationship between renal arterial pressure and renin release was examined in anesthetized dogs during complete or partial ureteral constriction. During complete ureteral occlusion ureteral pressure rose to 95+/-4 mm Hg and renin release increased from 1.7+/-0.7 to 22.3+/-3.1 mug/min; renal blood flow (RBF) was not significantly changed. Renin release was not further increased during subse...
blood pressure rises rapidly upon awakening and maybe responsible, in part, for the increased incidence of myocardial infarction and stroke during the morning hours. the aim of the present study was, therefore, to develop a novel chronotherapeutic formulation of metoprolol tartrate (mt) for night time dosing providing maximum effect in the morning hours. core tablets contained mt, sodium chlori...
Introduction: Tuberculosis (TB), with different types of respiratory tract involvements, has a high rate of mortality all around the world. Endobronchial involvement, which is a slightly common tuberculous infection, requires special attention due to its severe complications such as bronchostenosis. Aim of study of this study was describes, one type of pulmonary tuberculosis with less diagnosed...
BACKGROUND Patients with nocturnal hypertension are at higher risk for cardiovascular complications such as myocardial infarction and cerebrovascular insult. Published studies inconsistently reported decreases in nocturnal blood pressure with melatonin. METHODS A meta-analysis of the efficacy and safety of exogenous melatonin in ameliorating nocturnal blood pressure was performed using a rand...
This study aimed at compare influences of airway pressure release ventilation (APRV) and Synchronized Intermittent Mechanical Ventilation (SIMV) on intracranial pressure and oxygenation status in patients with traumatic brain injuries. A clinical trial was carried out in 40 patients with traumatic brain injuries in the intensive care unit in Kamyab neurosurgery Hospital, Mashhad, Iran. The pati...
