BACKGROUND We investigated the effect of acute hypothyroidism on lipid concentrations especially on high density lipoprotein (HDL-cholesterol) level in athyroatic patients. MATERIALS AND METHODS Thirty-one patients, with a history of differentiated thyroid carcinoma and total thyroidectomy, who were candidates of radioiodine therapy, enrolled in the study. Their lipid profiles and serum thyro...

NE type of viable chromosomal rearrangement frequently induced 0 by X-ray treatment is a translocation in which a piece of a chromosome is taken from its normal position and inserted into some other part of the chromosomal complex. When such a rearrangement is intrachromosoma1 the name “transposition” is applied and when it involves two chromosomes it is called an insertional translocation. A n...

OBJECTIVES Instruction of local anesthesia injection in an important part of dental education curricula. This study was performed to compare dental students' preference with regard to tactile or visual determination of injection site for an inferior alveolar nerve block (IANB) in children. MATERIALS AND METHODS This crossover randomized clinical trial was conducted on dental students of Zahed...

Any future Internet architecture must offer improved protection and resilience over today’s network, which is subject to pervasive and persistent attacks. A recently emerging architecture, Named-Data Network (NDN), treats content as the primitive entity. This leads to decoupling location from identity, security and access, and retrieving content by name. NDN security is based on the establishme...

Activity of the P family of transposable elements in Drosophila melanogaster is regulated primarily by a cellular condition known as P cytotype. It has been hypothesized that P cytotype depends on a P element-encoded repressor of transposition and excision. We provide evidence in support of this idea by showing that two modified P elements, each with lesions affecting the fourth transposase exo...

The ph(P1) allele of Drosophila melanogaster encodes a chimeric P-Ph protein that contains the DNA-binding domain of the P-element transposase and the Ph protein lacking 12 amino-terminal amino acids. It has been shown that the P-Ph protein is responsible for the formation of a repressive complex on P elements inserted at the yellow locus. Here we demonstrate that an enhancer element can suppre...

Multi-exponent algorithms are frequently used in cryptographic protocols, for example, digital signature algorithms, some commitment schemes, etc. The previously known efficient algorithms use special exponent recording algorithms like wNAF or the joint sparse form. Those algorithms can only be applied starting at the least significant bit. Therefore, they require additional memory for the reco...

Although prostaglandins (PGs)-lipid signals produced downstream of cyclooxygenase (COX) enzymes-regulate actin cytoskeletal dynamics, their mechanisms of action are unknown. We previously established Drosophila oogenesis, in particular nurse cell dumping, as a new model to determine how PGs regulate actin remodeling. PGs, and thus the Drosophila COX-like enzyme Pxt, are required for both the pa...

we consider the concept of ω-distance on a complete partially ordered g-metric space and prove some common fi xed point theorems.

the wiener index $w(g)$ of a connected graph $g$‎ ‎is defined as $w(g)=sum_{u,vin v(g)}d_g(u,v)$‎ ‎where $d_g(u,v)$ is the distance between the vertices $u$ and $v$ of‎ ‎$g$‎. ‎for $ssubseteq v(g)$‎, ‎the {it steiner distance/} $d(s)$ of‎ ‎the vertices of $s$ is the minimum size of a connected subgraph of‎ ‎$g$ whose vertex set is $s$‎. ‎the {it $k$-th steiner wiener index/}‎ ‎$sw_k(g)$ of $g$ ...
