The Y chromosome is a unique genetic environment defined by a lack of recombination and male-limited inheritance. The Drosophila Y chromosome has been gradually acquiring genes from the rest of the genome, with only seven Y-linked genes being gained over the past 63 million years (0.12 gene gains per million years). Using a next-generation sequencing (NGS)-powered genomic scan, we show that gen...

background: centre of pressure displacement is an indicator of postural control. children with cerebral palsy have poor postural control. one common intervention to enhance their balance is vestibular stimulation. the aim of this research was to investigate the effect of vestibular stimulation on cop parameters in children with cerebral palsy (3-10 years old). methods: this study was a randomiz...

background the prevalence of epilepsy in the elderly is more than other age groups and treatment of epilepsy in this group is challenging for neurologists. the purpose of this study is to compare the efficacy and safety of phenytoin versus oxcarbazepine in the elderly patients with newly diagnosed secondary generalized seizure. material and methods we enrolled 142 elderly patients with epilepsy...

let g be a graph with p vertices and q edges and a = {0, 1, 2, . . . , [q/2]}. a vertex labeling f : v (g) → a induces an edge labeling f∗ defined by f∗(uv) = f(u) + f(v) for all edges uv. for a ∈ a, let vf (a) be the number of vertices v with f(v) = a. a graph g is said to be vertex equitable if there exists a vertex labeling f such that for all a and b in a, |vf (a) − vf (b)| ≤ 1 and the in...

OBJECTIVE The main aims of this study were to explore the molecular structural relationship between Human epididymis protein 4 (HE4) and Lewis y antigen by determining their expression patterns and clinical significance in ovarian epithelial carcinoma. METHODS The structural relationship between HE4 and Lewis y antigen was examined using immunoprecipitation and confocal laser scanning microsc...

Neuropeptide Y (NPY) is an inhibitory neuromodulator expressed abundantly in the central nervous system that is suspected of being an endogenous antiepileptic agent that can control propagation of limbic seizures. Electrophysiological and pharmacological data suggest that these actions of NPY are mediated by G protein-coupled NPY Y2 and NPY Y5 receptors. To determine whether the NPY Y5 receptor...

The competition graph of a digraph is defined to be the intersection graph of the family of the out-neighborhoods of the vertices of the digraph (see [6] for intersection graphs). A digraph D is a pair (V (D), A(D)) of a set V (D) of vertices and a set A(D) of ordered pairs of vertices, called arcs. An arc of the form (v, v) is called a loop. For a vertex x in a digraph D, we denote the out-nei...

Objective Selection of sperm for intra-cytoplasmic sperm injection (ICSI) is usually considered as the ultimate technique to alleviate male-factor infertility. In routine ICSI, selection is based on morphology and viability which does not necessarily preclude the chance injection of DNA-damaged or apoptotic sperm into the oocyte. Sperm with high negative surface electrical charge, named “Zeta p...

— We study three sequences of polynomials defined as successive derivatives with respect to a differential operator associated with a grammar (one of these sequences was originally introduced by Ramanujan). Combinatorial interpretations for these polynomials are found in terms of rooted trees and graphs of mappings from [n] to [n]. Introduction Dans [Ra], [B], Ramanujan (et B. Berndt à sa suite...
