let g be a group. a subset x of g is a set of pairwise noncommuting elements if xy ̸= yx for any two distinct elements x and y in x. if |x| ≥ |y | for any other set of pairwise non-commuting elements y in g, then x is said to be a maximal subset of pairwise non-commuting elements. in this paper we determine the cardinality of a maximal subset of pairwise non-commuting elements in any non-abelian...

BACKGROUND It is not well established whether the increased number of leukocytes in the seminal fluid impairs the outcomes of assisted reproductive technology (ART). This investigation analysed the outcomes of the intracytoplasmic sperm injection (ICSI) and intracytoplasmic morphologically selected sperm injection (IMSI) cycles in couples in which the male partner exhibited leukocytospermia. ...

The aim of this study was to evaluate the reproductive efficiency of short and long term treatment with progestagens in addition to pregnant mare serum gonadotropin (PMSG) in Arabian ewes during the non-breeding season. A total of 56 ewes were divided into three groups: in group I vaginal sponges (60 mg medroxy progesterone acetate; MAP) were applied and removed after 6 days; in group II, vagin...

INTRODUCTION The laparoscopic and endoscopic approaches to internal drainage of pancreatic pseudocysts (PP) are the current minimally invasive management options. Indications, and early and late results of endoscopic and laparoscopic approaches are being discussed. AIM To present experience in treatment of PP by laparoscopic pseudocystogastrostomy (LPGS) and endoscopic pseudocystogastrostomy ...

let $g$ be a non-abelian group of order $p^n$‎, ‎where $nleq 5$ in which $g$ is not extra special of order $p^5$‎. ‎in this paper we determine the maximal size of subsets $x$ of $g$‎ ‎with the property that $xyneq yx$ for any $x,y$ in $x$ with‎ ‎$xneq y$‎.

Results The study group comprised 317 FMF patients (170 females, 147 males) with a mean age of 12.2 ± 5.7 years. There were 267 patients (84.3%) in group I and 50 patients (15.7%) in Group II. Median attack frequency before colchicine therapy was 24/year in Group I and 12/year in Group II (p<0,05). Although the frequency of majority of the clinical features did not differ between the groups, fe...

BACKGROUND In this report, we compare the long-term outcome of pediatric liver transplantation (LTx) patients maintained with tacrolimus-based and with cyclosporine (CsA)-based immunosuppressive therapy. We examine long-term patient and graft survival, the incidence of rejection, and immunosuppression-related complications. METHOD There were 233 consecutive primary LTx in children (ages <18 y...
