The effects of different solvents, temperature conditions, solvent-solid ratios and particle sizes on solid-solvent extraction of the total phenolics, proanthocyanidins and flavonoids herein also referred to as antioxidant from pomegranate marc peel (PMP) was studied. Water, methanol, ethanol, acetone, and ethyl acetate extraction efficiencies at extraction times of 0.17 to 10 min, extraction t...

The underlying mechanisms of lung endothelial injury after intestinal ischemia-reperfusion (I/R) injury are not fully known. Here we investigated the effects of posttreatment with a neutrophil elastase inhibitor (NEI; ONO-5046) on lung injury after intestinal I/R injury in a rat model. Intestinal I/R was produced by 90 min of ischemia followed by either 60 or 240 min of reperfusion. For all exp...

UNLABELLED Our purpose was to evaluate the safety profile and biodistribution behavior in healthy human volunteers of the new myocardial perfusion tracer bis[(dimethoxypropylphosphanyl)ethyl]ethoxyethylamine N,N'-bis(ethoxyethyl)dithiocarbamato nitrido technetium(V) (99mTc-N-DBODC). METHODS Ten healthy male volunteers were injected with 99mTc-N-DBODC under both stress and rest conditions. Ant...

Background: Tension-free inguinal hernioplasty is sine-qua-non for a good hernia repair and is aptly fulfilled by both Lichtenstein’s mesh and a correctly done Abrahamson’s darn. Aims: This study compares the increasingly popular, yet costly, Lichtenstein’s mesh repair with the classical Abrahamson’s darn repair for inguinal hernia. Materials and Methods: A randomized, bias-free study was condu...

Germ-tube emergence in Aspergillus nidulans exhibits partial synchrony. Germ tubes were first detected at 210 min. after inoculation of spores into a liquid medium. Almost all spores produced germ tubes within 360 min., 4 9 3 % of them doing so between 240 and 300 min. Increase in dry weight was first detected at 120 min. and various constituents at the following times: RNA (30 min.), Kjeldahl ...

In the present study the pharmacokinetics and pharmacodynamics of tamsulosin were investigated in anesthetized male dogs. Hypogastric nerve stimulation elevated the intraurethral pressure (IUP), which was inhibited dose dependently by intraduodenal administration of tamsulosin (3-30 microg/kg). The inhibition peaked about 90 min after dosing and lasted up to 240 min. The basal mean blood pressu...

Proline accumulation is a common biochemical indicator for assessing environmental stress in plants. The objective of this study was to determine the effect of various doses of two types of magnetic fields on date palm (Phoenix dactylifera L. (cv. Khalas) seedlings based on proline accumulation. The first type involved static magnetic field (SMF) generated by an electromagnetic circuit set at 1...

PURPOSE To investigate the protective effects of ischemic pre and postconditioning, as well as the association of both methods, in skeletal muscle injury produced by ischemia and reperfusion in rats. METHODS An experimental study was designed using 40 Wistar rats divided in four groups (n=10): Control - rats submitted to ischemia for 240 minutes (min) and reperfusion for 60 min; Ischemic prec...

Intracellular collagen degradation by fibroblasts is an important but poorly understood pathway for the physiological remodeling of mature connective tissues. The objective of this study was to determine whether gingival fibroblasts that express endogenous alpha(2)beta(1) integrin, the collagen receptor, would exhibit the cellular machinery required for phagosomal maturation and collagen degrad...

kilka fish are known as the main industrial and pelagic species of iran that are captured abundantly in the southern caspian sea. this study was conducted to survey the effectiveness of refinement steps on kilka (clupeonella delicatula) crude oil quality and fatty acid profiles. neutralization, bleaching, winterization and deodorization were performed on crude oil with deodorization done under ...
