In this study, the hepatoprotective effect of the methanol extract of aerial parts (shoot) from Otostegia persica Boiss (Golder) was investigated against the carbon tetrachloride (CCl4)-induced acute hepatotoxicity in male rats. Liver damage was induced through the oral administration of 50% CCl4 in liquid paraffin (2.5 mL/Kg bw, per os) 60 min after the administration of the methanol extract o...

Potassium (K(+)) is one of the essential nutrient elements for plant growth and development. Plants absorb K(+) ions from the environment via root cell K(+) channels and/or transporters. In this study, the Shaker K(+) channel Os-AKT1 was characterized for its function in K(+) uptake in rice (Oryza sativa) roots, and its regulation by Os-CBL1 (Calcineurin B-Like protein1) and Os-CIPK23 (CBL-Inte...

Five ethylene receptor genes, OS-ERS1, OS-ERS2, OS-ETR2, OS-ETR3, and OS-ETR4 were isolated and characterized from rice. The genomic structure of OS-ERS1 and OS-ERS2 revealed that the introns within the coding sequences occurred in conserved positions to those of At-ETR1 and At-ERS1, whereas each of the OS-ETR2, OS-ETR3, and OS-ETR4 genes contained 1 intron within its coding region located at a...

Anomalously high platinum group element concentrations have previously been reported for Upper Triassic deep-sea sediments, which are interpreted to be derived from an extraterrestrial impact event. Here we report the osmium (Os) isotope fingerprint of an extraterrestrial impact from Upper Triassic chert successions in Japan. Os isotope data exhibit a marked negative excursion from an initial O...

In this work, we dissect the performance of  two modern Perdew-Burke-Ernzerhof (PBE)-based double-hybrid (DH) density functionals to predict the isotropic and anisotropic polarizabilities of water nanoclusters (H2O)n [n = 2-6]. The considered models include the cubic integrand (CI) and quadratic integrand (QI) functions as well as the spin-opposite-scaled...

Butter, margarine and butter oil are three products which consume daily by Iranian’scommunity. Detection of type and existence of synthetic antioxidants (SAs) quantities in the margarine, butter and butter oil samples is so important in point of view of the safety. For this purpose, peroxide value (PV), oxidative stability (OS), iodine value (IV), fatty acid analysis (FA), type and amount of SA...

Background The aim of this study was to determine oxidative stress (OS) parameters after testicular torsion/detorsion in adult rats. MaterialsAndMethods In this experimental study, male adult Wistar rats were divided into four groups, each consisting of seven animals: group I-one hour right testicular torsion with subsequent orchiectomy, group II-one hour right testicular torsion followed by de...

osteosarcoma (os) is a malignant mesenchymal tumor, which rarely occurs in the maxilla. although variable histologic and radiographic features of os have been reported previously, in the majority of the cases painful swelling of the jaw is mentioned as the first clinical presentation. furthermore, early diagnosis and wide surgical resection of the tumor are the most important determinant factor...
