background: arthroscopic intervention is very common for conducting orthopedic surgeries. after a knee arthroscopic surgery, different drugs are used through intra-articular administration to induce analgesia. the aim of this study was to evaluate analgesic effects of bupivacaine (marcaine), bupivacaine plus midazolam, and bupivacaine plus fentanyl in reducing pain after knee arthroscopic surge...

a $p$-group $g$ is called a $mathcal{cac}$-$p$-group if $c_g(h)/h$ is ‎cyclic for every non-cyclic abelian subgroup $h$ in $g$ with $hnleq‎ ‎z(g)$‎. ‎in this paper‎, ‎we give a complete classification of‎ ‎finite $mathcal{cac}$-$p$-groups‎.

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 Urotensin II is a vasoactive polypeptide. It is known that some vasoactive polypeptides are produced and secreted by tumor cells, and act as a paracrine growth stimulant. The aim of this study was to examine the relationship between urotensin II and its receptor's messenger RNA expression in breast cancer. MATERIAL/METHODS Fifty-nine women with breast cancer were included in this s...

BACKGROUND The standard treatment for patients with renal and/or ureteral malignancies is radical nephrectomy or nephroureterectomy. Frequently, intra-abdominal extra-urinary lesions are noted preoperatively or intra-operatively in the gastrointestinal or gynecologic tract. We reviewed our experience with patients during an 11-year period. METHODS From 1991 through 2001, 1059 patients underwe...

In this paper we show another representations of extra-special 2-groups. Based on this new representation, we infer a M matrix which obeys the extra-special 2-groups algebra relations. We also derive a unitary R̆(θ, φ)matrix from theM using the Yang-Baxterization process. A Hamiltonian for the two qubits is constructed from the unitary R̆(θ, φ) matrix. In this way, we study the Berry phase and en...

In group-living species with male dominance hierarchies where receptive periods of females do not overlap, high male reproductive skew would be predicted. However, the existence of female multiple mating and alternative male mating strategies can call into question single-male monopolization of paternity in groups. Ring-tailed lemurs (Lemur catta) are seasonally breeding primates that live in m...

Many patients with few cerebral metastases receive radiosurgery alone. The goal of this study was to create a tool to estimate the survival of such patients. To identify characteristics associated with survival, nine variables including radiosurgery dose, age, gender, Eastern cooperative oncology group performance score (ECOG-PS), primary tumor type, number/size of cerebral metastases, location...
