Summary The exact mechanism of migraine pathophysiology still remains unclear due to the complex nature pain. Salmon calcitonin ( SC ) exhibits antinociceptive effects in treatment various pain conditions. In this study, we explored mechanisms underlying analgesic effect salmon on migrane using glyceryltrinitrate GTN )‐induced model and ex vivo meningeal preparations rats. Rats were intraperitoneally administered saline, (10 mg/kg), vehicle, saline + , (50 μg/kg) alone. Also, applied...

Soluble ACE2 (sACE2) decoys are promising agents to inhibit SARS-CoV-2, as their efficiency is unlikely be affected by escape mutations. However, success limited relatively poor potency. To address this challenge, multimeric sACE2 consisting of SunTag or MoonTag systems developed. These extremely effective in neutralizing SARS-CoV-2 pseudoviral and clinical isolates, perform better than the dimeric trimeric sACE2, exhibit greater 100-fold neutralization efficiency, compared monomeric sACE2....

Aim: The aim of this study was to evaluate the effect Hypericum perforatum (HP) oil on wound-healing process in rabbit palatal mucosa. Materials and Methods: Thirty-six New Zealand albino rabbits were randomly allocated following groups; (1) HP (test, n = 18) (2) olive (control, 18). Palatinal excisional wounds created oils topically applied (0.1 ml, 30 s, twice a day). Gingival biopsies excised, analyzed for re-epithelialization (RE) granulation tissue maturation (GTM) days 3, 7, 14 after...

The aim of this study is to investigate the effects Protocatechuic acid and Corchorus olitorius on streptozotocin (STZ) induced diabetic rat testis tissue. Randomly selected Wistar Albino rats were divided into five groups as; Diabetes Mellitus, Mellitus treated with Olitorus (STZ+CO), Protacatechuic (STZ+PCA), (CO), (PCA) Control. Diabetic model was generated by intraperitoneal injection 60 mg/kg Streptozotosin. After 48 hours STZ injection, blood samples collected from tail vein in order...

Liver ischemia/reperfusion (IR) often affects distant organs, such as small intestine, kidney, and lung. Coriandrum sativum (CS) has an antioxidant anti-inflammatory effect on liver damage. The aim of this study was to investigate the antiapoptotic effects CS extract lung, kidney after IR injury. Small tissues were evaluated scored in terms cell degeneration, inflammation, congestion, well caspase-3 (Cas-3) cluster differentiation 31 (CD31) immunostainings carried out. Renal enzymes,...

Following an injury or resection, the mammalian liver has capacity to regain its former volume and functioning by restoring itself. Studies have demonstrated that antioxidants play a role in hepatic regeneration. This study investigated effect of 4-(3,4-dihydroxybenzoyloxymethyl) phenyl-O-β-D-glucopyranoside (PG) obtained from Origanum micranthum on Sixty Wistar Albino rats were used. In sham-operated group, midline abdominal laparotomy was performed without hepatectomy. partial hepatectomy...

Abstract Soluble ACE2 (sACE2) decoy receptors are promising agents to inhibit SARS-CoV-2, as their efficiency is less likely be affected by common escape mutations in viral proteins. However, success may limited relatively poor potency. To address this challenge, we developed a large library of sACE2 fusion proteins, generated with several protease inhibitors or multimerization tags. Among these decoys, multimeric consisting SunTag MoonTag systems, which were originally utilized for signal...

Anti-Müllerian hormone (AMH) and Inhibin B (INHB) in the glycoprotein structure are members of transforming growth factor β family expressed by granulosa cells from puberty. AMH is a that increases life span small developing follicles. For this reason, it widely used to determine ovarian reserve age. Inhibin-B secreted plays role regulation Follicle Stimulating Factor (FSH) determination follicle diameter. There few studies on effect these two age-related hormones histology rats. In study,...
