Role of G-proteins and phosphorylation in the distribution of AGS3 to cell puncta.

Activator of G-protein signaling 3 (AGS3, also known as GPSM1) exhibits broad functional diversity and oscillates among different subcellular compartments in a regulated manner. AGS3 consists of a tetratricopeptide repeat (TPR) domain and a G-protein regulatory (GPR) domain. Here, we tested the hypothesis that phosphorylation of the AGS3 GPR domain regulates its subcellular distribution and functionality.

Protective role of erdosteine pretreatment on oleic acid-induced acute lung injury.

Background: Erdosteine is a mucolytic agent with antioxidant and anti-inflammatory effects. We evaluated the protective effect of erdosteine pretreatment on oleic acid (OA)-induced acute lung injury.

Materials And Methods: Twenty-four male Wistar Albino rats were assigned to four treatments: control (oral saline + 50 μL intravenous [i.

Zofenopril attenuates injury induced by ischemia-reperfusion on rat ovary.

Aim: The aim of the study was to investigate the effectiveness of zofenopril in an experimental model of ovarian torsion in rats with histologic and biochemical assessments.

Material And Methods: Experimental procedures were performed on 35 female rats (Wistar albino). Rats were randomly divided into five groups as: sham (sham operated, n = 7); vehicle group 1 (torsion-detorsion, n = 7) with 2 h ischemia and 2 h reperfusion; vehicle group 2 (torsion-detorsion, n = 7) with 2 h ischemia and 5 days' reperfusion; zofenopril group 1 (torsion-detorsion, n = 7) with 2 h ischemia, 2 h reperfusion and a signal dose of oral 15 mg/kg zofenopril; and zofenopril group 2 (torsion-detorsion, n = 7) with 2 h ischemia, 5 days' reperfusion and 5 days' oral 15 mg/kg zofenopril.

Protective effect of colchicine on ovarian ischemia-reperfusion injury: an experimental study.

Objective: The aim of the present study is to investigate the efficiency of colchicine in the experimental rat ovarian torsion model in the light of histological and biochemical data.

Study Design: A total of 35 Wistar albino female rats were randomly divided into 5 groups, group 1: (control-sham operated, n = 7); group 2: (torsion/detorsion, n = 7) 2 hours of ischemia and 2 hours of reperfusion; group 3: (torsion/detorsion, n = 7), 2 hours of ischemia and 5 days of reperfusion; group 4: (torsion/detorsion, n = 7) 2 hours of ischemia and 2 hours of reperfusion and a signal dose of oral 1 mL/kg colchicine; and group 5: (torsion/detorsion, n = 7), 2 hours of ischemia and 5 days of reperfusion and 5 days of oral 1 mg/kg colchicine. Histopathologic evaluation was performed by a scoring that assesses congestion, bleeding, edema, and cellular degeneration in the ovarian tissue.

Protective effect of leflunomide against oxidative intestinal injury in a rodent model of sepsis.

Background: Sepsis is defined as an uncontrolled inflammatory response in a host. The process may lead to severe sepsis, multisystem organ failure and even death. Leflunomide has important immunomodulatory and anti-inflammatory effects, which may mitigate host response to bacterial translocation.
