The inability of pre-emergence herbicides alone to give season-long weed control in maize production justifies the need for supplementary control. Field trials were conducted evaluate intercropped groundnut and jack bean enhanced efficacy two 2013/2014 2015 cropping seasons at Federal University Agriculture, Abeokuta, Nigeria. experiment was arranged split-plot fitted a randomized complete bloc...
Objectives This study evaluated the amount of remaining root canal filling materials after retreatment procedures performed by undergraduate students using manual, rotary, and reciprocating techniques through micro-computed tomographic analysis. The incidence of instrument fracture and the instrumentation time were also evaluated. Materials and Methods Thirty maxillary single rooted teeth wer...
OBJECTIVES We investigated whether the Na+-H+ exchange inhibitor, HOE642 (Hoe), and/or the Na channel blocker, mexiletine (Mex), enhance a cardioprotective effect on St. Thomas' Hospital cardioplegic solution (STS) to clarify the mechanism by which intracellular Na+ is accumulated after cardioplegic arrest. MATERIALS AND METHODS Isolated working rat hearts were perfused with Krebs-Henseleit b...
Acute hypertension inhibits proximal tubule (PT) fluid reabsorption. The resultant increase in end proximal flow rate provides the error signal to mediate tubuloglomerular feedback autoregulation of renal blood flow and glomerular filtration rate and suppresses renal renin secretion. To test whether the suppression of the renin-angiotensin system during acute hypertension affects the magnitude ...
field experiments were conducted in amirkabir sugarcane agro-industry (khuzestan province, iran) farms to evaluate the efficacy of integrated chemical and mechanical methods in controlling weeds. experiments were carried out in a split plot-randomized complete blocks design with four replications. the main plot consisted of four mechanical treatments, namely: hilling up, sweep cultivator, disc ...
BACKGROUND The accumulation of intracellular sodium during myocardial ischemia couples an inappropriate calcium influx and depressed cardiac recovery during subsequent reperfusion. The effects of the selective sodium/ hydrogen exchange inhibitor HOE 694 are evaluated during myocardial ischemia and reperfusion. METHODS Ten isolated rat hearts were subjected to a 2-minute infusion of St. Thomas...
Background: Nowadays, there's a growing demand for the natural antioxidants due to the harmful effects of synthetic antioxidants. Therefore, introduction of new natural antioxidants (especially those with plant origin) is very important. Objective: The present study explores the chemical constitution and antioxidant activity of leaf extract of Hyssopus officinalis L. and extract of aerial part...
We studied the role of brain kinins in the regulation of cardiovascular function. Intracerebroventricular injection of 380 pmol bradykinin increased mean blood pressure by 20 +/- 2 mm Hg (P < .01) in normotensive Wistar-Kyoto (WKY) rats. Complete inhibition of this effect was achieved with intracerebroventricular administration of the newly synthesized, long-acting B2 receptor antagonist D-Arg,...
objective: the aim of this study was to evaluate and compare the cleaning ability and instrumentation time of manual and rotary methods used for preparation of primary anterior teeth. materials and methods: forty-four primary anterior teeth were used in this experimental study. access cavities were prepared and india ink was injected into the canals. the samples were divided into three groups a...
