the incidence and hematological effects of helminth infection during pregnancy were investigated among pregnant women in isiala, mbano, southeast nigeria.totally 282 pregnant women were enlisted for the study between october 2011 and september 2012. stool samples were examined for intestinal helminths using formalin-ether sedimentation technique. hemoglobin (hb) and packed cell volume (pcv) lev...

the present study was undertaken to compare the in hospital results of coronary artery bypass graft (cabg) with (on pump) or without (off pump) cardiopulmonary bypass (cpb). data were collected on all first-time isolated cabgs with saphenous vein and/or artery grafts at shahid madani hospital in tabriz-iran, between 2006 and 2009. age and clinical profile were marched between on pump and off pu...

in this article cuo/water nanofluid was synthesized by using polyvinylpyrolidone (pvp) as the dispersant.  thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. to study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different ph values and pvp surfactant concentrations; also thermal conductivity...

background: few studies have shown the limitation of the world health organization (who)/ international council for the control of iodine defi ciency (iccidd)-adopted thyroid gland volume references as universal normative values for thyroid gland volume. so we decided to measure thyroid gland volume by sonography in schoolchildren in rasht, gilan province, iran — rasht is a metropolitan city on...

in recent years, biosurfactants due to wide applications in chemical, petroleum, food andpharmaceutical industries, have been widely considered by researchers. biosurfactants are produced by aseries of microorganisms, so it is important to screen culture medium and operating conditions in miniaturized bioreactors prior to scaling up to large bioreactors.in this study, using a kind of miniaturiz...

measurement of the stroke volume and its changes over time can be very helpful for diagnosis of dysfunctions in the blood circulatory system and monitoring their treatments. impedance cardiography (icg) is a simple method of measuring the stroke volume based on changes in the instantaneous mean impedanceof the thorax. this method has received much attention in the last two decades because it is...

background and aims. basic periodontal treatment aims at eliminating supra- and sub-gingival plaque and establishing conditions which will allow effective self-performed plaque control. this aim is primarily achieved with sonic and ultrasonic scalers. however, generation of bacterial aerosols during these procedures is of great concern to patients, the dentist and the dental assistant. the aim ...

amniotic fluid volume (afv) is one of the important parameters in the assessment of fetal well-being. the ability of ultrasound measurements to represent the actual afv is unproven. this study was undertaken to compare correlation of conventional amniotic fluid index (afi) and radial amniotic fluid index (rafi) as a new method with actual fluid volume on phantom. as an experimental study, 10 to...
