We introduce (dual) strongly relative CS-Rickart objects in abelian categories, as common generalizations of Rickart and extending (lifting) objects. gi...

background: stress is a cause of male infertility. although sex hormones and sperm quality have been shown to be low in stress, sperm physiology and testicular functional proteins, such as phosphotyrosine proteins, have not been documented. objective: to investigate the acrosome status and alterations of testicular proteins involved in spermatogenesis and testosterone synthesis in chronic stres...

Background: To determine the relationship between prepregnancy obesity and increasing risk of cesarean section (CS). Materials and Methods: The population studied included 887 women with live births after 37 weeks gestation in Shahid Sedoughi hospital between April 1, 2008, and April 1, 2009. Women who were obese before pregnancy were comparing with nonobese women with regard to mode of deliver...

preparation of chitosan (cs) microspheres as a novel drug delivery vehicle for intranasal immunization using high, medium and low cs molecular weight (mw) was investigated in this study. diphtheria toxoid (dt) was used as a model antigen. the emulsion-solidification method was adopted for microencapsulation of dt.  in the first step, following the purification of semi-crude dt by the ion-exchan...

Up until now, we have been introducing mathematical notation to capture concepts such as propositions, implications, predicates, and sets. We need this machinery in order to be able to argue properties of discrete structures in a rigorous manner. As we were introducing new concepts, we stated various facts and gave proofs of some of them, but we were not explicit about what a correct proof shou...
