background & objectives: good fasting practice is not only refraining from foods and drinks in a period of time, but should encompass several important factors including unexcessive eating habit during ifthor. understanding the effect of fasting accompanied by calorie restriction (cr) in oxidative stress indicators, malondialdehyde (mda) and 8-oxo-7,8-dihydro-2'deoxyguanosine (8-oxodg), th...

let $mathcal m$ be a factor von neumann algebra. it is shown that every nonlinear $*$-lie higher derivation$d={phi_{n}}_{ninmathbb{n}}$ on $mathcal m$ is additive. in particular, if $mathcal m$ is infinite type $i$factor, a concrete characterization of $d$ is given.

‎Let $M$ be a non-zero finitely generated module over a commutative Noetherian local ring $(R,mathfrak{m})$ with $dim_R(M)=t$‎. ‎Let $I$ be an ideal of $R$ with $grade(I,M)=c$‎. ‎In this article we will investigate several natural homomorphisms of local cohomology modules‎. ‎The main purpose of this article is to investigate when the natural homomorphisms $gamma‎: ‎Tor^{R}_c(k,H^c_I(M))to kotim...

epilepsy is one of the common neurologic disorders in children. drug side-effects are one of the important problems in treating patients with epilepsy. using the antiepileptic medication may cause different side effects such as disorder in bone and vitamin d metabolism. sodium valproate is one of the antiepileptic medications used widely. some of its side effects include digestive disorder, inc...

in this study 50 samples of ecstasy tablets seized in iran during the period of 2007 through 2008 were examined and their physical characteristics (appearance, marking, scored/not scored, color, weight, diameter, thickness) were determined. in order to determine the chemical characteristics of these tablets, color tests (marquis test, simon’s test, chen’s test and gallic acid test), thin layer ...

background: meict is the first chlorotoxin-like peptide isolated from the iranian scorpion mesobuthus eupeus. chlorotoxin (ctx) is a neurotoxin that specially binds to (mmp-2) on ma-lignant cells and now is used in treatment of glioma. in the present study, we have used homology modeling to propose the 3d structure of meictand analyze its interaction with mmp-2 and its snp types. methods:the st...

In this paper, we study a coupled system of nonlinear fractional differential equations with multi-point boundary condi- tions. The differential operator is taken in the Riemann-Liouville sense. Applying the Schauder fixed-point theorem and the contrac- tion mapping principle, two existence results are obtained for the following system D^{alpha}_{0+}x(t)=fleft(t,y(t),D^{p}_{0+}y(t)right), t in (0,...

covalent grafting of mcm-41 with 3-chloropropyl trimethoxysilane and subsequent reaction respectively with acacdien and complexation with moo2(acac)2 afforded moo2acacdien@mcm-41. x-ray diffraction and nitrogen sorption analyses revealed the preservation of the textural properties of the support as well as accessibility of the channel system despite sequential reduction in surface area, pore vo...

background: lymphomas are a group of malignancies affecting b, t and nk cells. cox-2 enzyme is one of the known inflammatory factors which increase in the inflammation process. increase in cox-2 expression inhibits apoptosis and increases tumor cells invasion and angiogenesis. increase in the cox-2 gene expression is seen in a group of cancers .specific cox-2 inhibition also can be beneficial i...

a novel catalytic synthesis of 3,3'-(arylmethylene)-bis-(4-hydroxy-2h-chromene-2-one) derivatives from a tandem condensation reaction of 4-hydroxycoumarin and aromatic aldehydes has been developed. the reaction occurs in water in the presence of melamine trisulfonic acid as catalyst to give the corresponding products in good to high yields. this green approach has several advantages such as sho...
