postconditioning is a simple and safe strategy for cardioprotection and infarct size limitation. our previous study showed that oxytocin (ot) exerts postconditioning effect on ischemic/reperfused isolated rat heart. the aim of this study was to investigate the involvement of ot receptor, mitochondrial atp-sensitive potassium channel (mkatp), nitric oxide (no) and cyclooxygenase (cox) pathways i...

Introduction: Cardiac preconditioning represents the most potent and consistently reproducible method of rescuing heart tissue from undergoing irreversible ischemic damage. The aim of the present study was to evaluate oxytocin (OT) induced cardioprotection and its signaling pathways on lactate dehydrogenase (LDH) and creatine kinase-MB isoenzyme (CK-MB) in the anesthetized rats. Methods: Ei...

background: the capability of embryonic carcinoma cells p19 in differentiation to cardiomyocyte was examined through inducing effects of oxytocin (ot) and 5-azacytidin (5az) individually and compared with each other in laboratory condition. materials and methods: p19 embryoid bodies (ebs) was formed through hanging drops method. then, ebs were treated with (5az) or (ot) and the eb medium (ctrl)...

A structurally simple, highly reactive chlorinating reagent, N-chloro-N-fluorobenzenesulfonylamine (CFBSA), was conveniently prepared from inexpensive Chloramine B in high yield. A wide range of substrates were chlorinated with it to obtain products in good to high yields and appropriate selectivity.

Malaria, a febrile illness mostly confined to the tropical countries is transmitted by bite of infected female Anopheles mosquito. In 2015 alone, 88% of the malaria burden and 90% deaths due to malaria were confined to the African and Asian countries. Although number of tests are available for rapid diagnosis and screening for malaria, peripheral blood smear examination remains the gold standar...

BACKGROUND Hematoxylin and eosin (H&E) is not an optimal stain to discriminate chief cells from parietal cells in gastric biopsies MATERIALS AND METHODS Fifteen sets of biopsies from the gastric corpus were consecutively stained with H&E and toluidine blue stains; chief cells stained deep blue with toluidine blue, thus contrasting with lightly-stained parietal cells. In well-oriented sections...

Operation Theatre (OT) is the most important area where precise controlled on indoor air quality is required because it is directly related to patient health and its recovery period. This work aims to study and visualize the airflow distribution of conventional flat air diffuser ventilation system and newly designed angular air ventilation system in OT. Angular Air Distribution (AAD) system is ...

Previous studies have suggested that oxytocin (OT) may be anxiolytic in female laboratory rats and mice. The elevated plus-maze was used to compare anxiety-related behaviors of OT-deficient (OT-/-) and wild-type (OT+/+) mice. Female OT-/- mice displayed increased anxiety-related behavior compared with OT+/+ mice. The percentage of entries (P < 0.0002) and time spent (P < 0.003) in the open arms...

background: an enchondroma is a benign and a well-differentiated chondrosarcoma is an invasive chondroid tumor with high recurrence potential. in spite of biologic differences, these two tumors have very similar histopathologic appearance. it has been shown that the biologic nature of the connective tissue around benign and malignant tumors varies in the number of mast cells. the aim of this st...
