high yield photolytic reduction of a series of thiaphosphoranes z p sr to give z p h with uv-light-induced tri-n-butyltin hydride through phosphoranyl radical z p is described. this reaction is inhibited by a-methylstyrene and initiated by a radical initiator such as azobisisobutyronitrile

radical feminism is definable as a movement in second half of twentieth century that considers patriarchy or maledomination at the root of women’s oppression. according to this idea, the problem is born within the family and non equal relations between it’s male and female members, and then from hear goes to society and politics. the radical feminists were inspired by dominant discourse of new ...

discussion of the many faces of relativism occupies a highly prominent place in the epistemological literature. protagoras in ancient greece and nelson goodman in the modern period are two most notable proponent of relativism. in the present article, i discuss and explain relativistic approaches of this two important relativist. i will first briefly define and review some faces of relativism. t...

reactions of free radicals and reactive oxygen species (ros) with biological molecules in vivo play an important physiological role in many diseases. 2,2-diphenyl-1-picrylhydrazyl (dpph) is a stable free radical and often used as a routine reagent to evaluate the antioxidant capacity of an antioxidant. this study was undertaken to investigate the free radical-scavenging and antioxidant activiti...

Background & Aim: Chorisia is an important Bombacaceous plant that is traditionally used for a variety of ailments. Due to its richness in several bioactive phytocompounds, some Chorisia species showed a wide range of important biological effects. Accordingly, the present work was undertaken to comparatively evaluate the antioxidant potential and effects on adipogenesis of <em...

Let $k$ be field of characteristic $p$, andlet $G$ be any finite group with splitting field $k$. Assume that $B$ is a $p$-block of $G$.In this paper, we introduce the notion of radical $B$-chain $C_{B}$, and we show that the $p$-local rank of $B$ is equals the length of $C_{B}$. Moreover, we prove that the vertex of a simple $kG$-module $S$ is radical if and only if it has the same vertex of th...

background: this study compared the early success, complication and patient satisfaction rates of modified extraperitoneal radical cystectomy (mainz ii urinary diversion) with standard intraperitoneal radical cystectomy (continent ileocecal urinary diversion) in a group of patients with muscle invasive urothelial carcinoma of the urinary bladder. methods: from september 2009 until november 2013...

conclusions there were no significant differences in the survival rates and short-term postoperative complications between the laparoscopic partial nephrectomy group and the laparoscopic radical nephrectomy group for small rcc, but the former was slightly more effective. background renal cell carcinoma (rcc) is a common malignancy of the urinary system with high rates of morbidity and mortality...
