recent studies have shown that glucocorticoids may have modulatory effect on anxiety reactions. this effect may occur with opioid system interference. according to that, the purpose of this research is to assess the effect of dexamethasone as glucocorticoid agonist and its interaction with opioidergic system on the anxiety modulatory effect in plus maze model in mice. male white mice with mediu...

The heat loss through the walls of Internal Combustion Engines (ICEs) needs to be minimized and improved since it has a detrimental impact on overall thermal efficiency engine. This study focuses investigating transfer in flat-wall impinging diesel spray flame, simulating conditions, optimize engine parameters. effects factors such as various injection pressures, nozzle hole diameters, impingem...

background: monitoring of post-operative pain is one of the most important problems for patient and surgeon. using a method with minimal pain and disability is desirable for both sides. this study aimed to compare analgesic effects of subcutaneous and subfascial administration of marcaine in inguinal hernia surgery. methods: in a double blind randomized controlled trial, 128 cases of unilateral...

Background and Objective: The effect of opioids on the reproductive system has been studied as an attractive research field. In this study, the effect of morphine as an analgesic opioid was evaluated on the ovarian polycystic induction in the rat. Materials & Methods: In this study, 24 female virgin Wistar rats weighing 200-250 g were injected with morphine (1-10 mg/kg/day) for 9 days. Control ...

Objective : Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders that can lead to irregular menstrual cycles and hyperandrogenism. Reduced levels of progesterone and increased estrogen in these women can perpetually stimulate the endometrial tissue of the uterus. In this study, the effect of PCOS induction was studied using estradiol valerate. MaterialsAndMethods Adult ...

Introduction: In implantation, endometrial epithelium is affected by the release of steroid hormones secreted from the ovary and allows the blastocyst to bind. This course is called the “implantation window” and occurs about 4-10 days after the onset of progesterone secretion. Therefore, the endometrium undergoes changes in the configuration of microvilli in the apical membrane, as well as the ...

A 2.0T gasoline engine was modified to a dual-injection engine. Numerical simulation method is used study the influence of fuel type and injection strategy on in-cylinder mixture formation process, combustion process soot emission The results show that an appropriate increase in intake port ratio can improve uniformity air-fuel mixture. Increasing system, proportion directly injected into cylin...

A combined experimental and numerical investigation of partially premixed laminar methane-air flames undergoing side-wall quenching (SWQ) is performed. well-established SWQ burner adapted to allow the seeding main flow with additional gaseous products issued from a (secondary) wall inlet close flame’s point. First, characteristics flame that quenches at are assessed using planar laser-induced f...

A crude cell wall fraction of Listeria monocytogenes was prepared by sonic disruption and differential centrifugation of viable, washed cultures. When injected into mice, this sterile, crude cell wall fraction protected mice against an intraperitoneal challenge with 18 to 85 50% mean lethal dose of L. monocytogenes. Resistance was greatly enhanced when bacterial endotoxin (lipopolysaccharide) w...

An advanced chromodynamics, Rothmann-Keller (RK) type lattice Boltzmann model (LBM) is used in this study. The new benefits from high stability and capability of independently setting the interfacial tension fluids as an input parameter. In addition, coupled with a wall-density approach to simulate hydrophilic or hydrophobic properties wall surfaces. Finally, injection wetting (non-wetting) flu...
