In this paper, we introduce the notion of the radical of a $PMV$-algebra $A$ and we charactrize radical $A$ via elements of $A$. Also, we introduce the notion of the radical of a $cdot$-ideal in $PMV$-algebras. Several characterizations of this radical is given. We define the notion of a semimaximal $cdot$-ideal in a $PMV$-algebra. Finally we show that $A/I$ has no nilpotent elemen...
Phenolic compounds including flavonoids and phenolic acids are plants secondary metabolites. Due to their ability to act as antioxidant agents, there is a growing interest to use those components in traditional medicine for cancer prevention or treatment. The aim of this study was to measure the amounts of total phenolics and flavonoids as well as anti-proliferative effect of aqueous extract of...
Free radical formation has been investigated in diverse experimental models of LPS-induced inflammation. Here, using electron spin resonance (ESR) and the spin trap alpha-(4-pyridyl-1-oxide)-N-tert-butylnitrone, we have detected an ESR spectrum of alpha-(4-pyridyl-1-oxide)-N-tert-butylnitrone radical adducts in the lipid extract of mouse skin treated with LPS for 6 h. The ESR spectrum was consi...

The influence of molecular structure (branched vs linear) on product formation in the heterogeneous oxidation of unsaturated organic aerosol is investigated. Particle phase product isomers formed from the reaction of squalene (C30H50, a branched alkene with six C═C double bonds) and linolenic acid (C18H30O2, a linear carboxylic acid with three C═C double bonds) with OH radicals are identified a...
PURPOSE Because laparoscopic radical prostatectomy remains a challenging procedure, rectal injury is always a potential complication. We review the incidence of rectal injuries at our institution in the first 110 consecutive laparoscopic extraperitoneal radical prostatectomies. MATERIALS AND METHODS Nine (8%) out of the first 110 laparoscopic extraperitoneal radical prostatectomies performed ...
چکیده این پژوهش با هدف مقایسه سبک های حل مسئله و باورهای خودکارآمدی در دانش آموزان دوره دبیرستان مدارس نمونه و عادی شهر شبستر در سال تحصیلی 1391-1390 با استفاده از روش تحقیق توصیفی - پیمایشی انجام گرفت. جامعه آماری تحقیق شامل تمامی دانش آموزان دبیرستان های نمونه و عادی شبستر با تعداد 3839 نفر بود و حجم نمونه 350 نفر با استفاده از روش نمونه گیری تصادفی طبقه ای انتخاب شد. برای گردآوری داده ها از...
The present study was carried out to evaluate the antimicrobial and antioxidant activities of methanol extract of Careya arborea (MECA) stem barks (Myrtaceae) in various in-vitro systems. Antimicrobial activities of MECA were carried out using disc diffusion methods with Gram positive and Gram negative bacteria and some fungal species. MECA showed broad-spectrum antimicrobial activity against a...
Photolysis of dibenzyl ketone derivatives adsorbed on ZSM-5 zeolites produces persistent benzyl radicals (initiator radicals), which add to methyl acrylates (monomers) to generate persistent adduct radicals. Both initiator and adduct radicals are readily observable by conventional steady-state EPR spectroscopy at room temperature and are persistent for time periods ranging from seconds to many ...
