background: there are many controversies reported about the association between blood lead levels and blood pressure among lead exposed workers. studies have suggested incorporating lifestyle factors along with blood lead levels. the present study aimed to evaluate the effect of lead exposure on blood pressure changes among lead exposed workers in contemplation of lifestyle factors. materials a...

background nasal septal deviation (nsd) can cause upper airway obstruction, which results in hypoxia and therefore, pulmonary vasoconstriction, ventricular hypertrophy and right-sided heart failure. objectives the aim of this study is to determine the mean pulmonary arterial pressure (mpap) of the patients with nsd and the effect of septoplasty on pulmonary arterial pressure. patients and metho...

conclusions both remifentanil and magnesium had favorable outcomes in preventing hr and map elevation after tracheal extubation. however, remifentanil was associated with more rapid regaining of consciousness and reversal of muscular relaxation. results the hr was significantly lower, immediately after extubation and 3, 5, and 10 minutes after extubation, in both magnesium and remifentanil grou...

sudden pipe expansions have been known as efficient hydraulic energy dissipaters for a long time. the complex phenomenon of flow separation and velocity discontinuity at the interface of incoming jet and the recirculation flow, results in intensive shear and tensile rupture of the fluid and the associated destructive phenomenon of cavitation. this paper focuses on aeration in sudden pipe expans...
