Objective: The genus Marrubium is used for treatment of joint pain, gout, stomach-ache and colic in Iranian Traditional Medicine. Marrubium astracanicum Jacq. (M. astracanicum) is a native species in the flora of Iran. The aim of this study was to evaluate the antinociceptive properties of various extracts of aerial parts of M. astracanicum.Materials and Methods: Antinociceptive activities of t...

Motivated by the problem of domain formation in chromosomes, we studied a co–polymer model where only a subset of the monomers feel attractive interactions. These monomers are displaced randomly from a regularly-spaced pattern, thus introducing some quenched disorder in the system. Previous work has shown that in the case of regularly-spaced interacting monomers this chain can fold into structu...

Introduction: In this study, Antibacterial and antioxidant activities of the essential oil and methanolic extract of the endemic plant, Zataria multiflora Boiss. have been studied. Method: The antioxidant potential of the samples was evaluated using two separate methods of inhibition of free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ammonium thiocyanate systems. Antibacterial activity wa...

Purpose: The aim of this study is to compare the amount of Bis-GMA, UDMA, and TEGDMA released from four different types of composite resins in three different time periods using the HPLC device. Materials and Methods: Four different composite resin materials with nanofiller content were used in the study. A total of 40 sample discs were prepared and polished to provide 10 pieces for each mater...

?-Diimine Ni and Pd complexes are one of the most examined late-transition organometallics in application catalyzed ethylene (co)polymerization. These organometallic catalysts provide unique advantages particular opportunities to tailor architectures, composition, topology synthesized polymers through polymerization. Two decades after their initial discovery, they still drawing extensive attent...

We show that certain DNA sequences have the ability to influence the positioning of RecA monomers in RecA-DNA complexes. A tendency for RecA monomers to be phased was observed in RecA protein complexes with several oligonucleotides containing a recombinational hotspot sequence, the chi-site from Escherichia coli. This influence was observed in both the 5' to 3' and 3' to 5' directions with resp...

Some of the Adamantane properties were calculated in this study. Chemical shift, free energy ofsolvation, free energy of cavity formation, Henry's law constant, and other properties ofAdamantane in dry phase, three solvents and three temperatures have been calculated with Abinitio method base on density functional theory (DFT) at B3lyp/6-31g, B31yp/6-31g*, B3lyp/6-31+g* and B3lyp/6-31++g** leve...

The present study was aimed to evaluate the effects of food simulating liquids and thermocycling on the elution of monomers from a nanofilled resin composite in different immersion times. Five Specimen discs were made from a nano-hybrid composite (Supreme 3M) for each group (Total = 180) and immersed in distilled water (control), citric acid, lactic acid, and 75% aqueous ethanol solution. The d...
