AIMS To study the distribution of longitudinal systolic strain and strain rate (SR) as indicators of myocardial deformation according to age and sex in a healthy population. METHODS AND RESULTS Longitudinal strain and SR were determined in 1266 healthy individuals from three standard apical views, using a combination of speckle tracking (ST) and tissue Doppler imaging (TDI) to track regions o...

This article covers a theory of dense subsets in general semigroups, including basic algebraic properties of dense and disjunctive subsets, characterizations of dense subset preserving homomorphisms and some remarkable properties of dense elements.

suppose that $h$ is a subgroup of $g$‎, ‎then $h$ is said to be‎ ‎$s$-permutable in $g$‎, ‎if $h$ permutes with every sylow subgroup of‎ ‎$g$‎. ‎if $hp=ph$ hold for every sylow subgroup $p$ of $g$ with $(|p|‎, ‎|h|)=1$)‎, ‎then $h$ is called an $s$-semipermutable subgroup of $g$‎. ‎in this paper‎, ‎we say that $h$ is partially $s$-embedded in $g$ if‎ ‎$g$ has a normal subgroup $t$ such that $ht...

A measure preserving action of a countably in nite group Γ is called totally ergodic if every in nite subgroup of Γ acts ergodically. For example, all mixing and mildly mixing actions are totally ergodic. This note shows that if an action of Γ is totally ergodic then there exists a nite normal subgroup N of Γ such that the stabilizer of almost every point is equal to N. Surprisingly the proof r...

Background: During lactation, metabolic changes in the bone in different areas of the body may affect the amount of bone mineral density.The aim of this study was to determine the relationship between breastfeeding and bone mineral density in women. Materials and Methods:  In this study, articles were searched at Cochran, Medline (via PubMed), Scopus, and Web of Science databases until June 201...

Introduction: Non-target radiation effects are damages and effects that occur without the need for direct radiation exposure in cells. Bystander signals cause non-targeted irradiation effect that has been defined as radiation responses in which non-irradiated cells exhibit irradiated effects as a result of signals from adjacent irradiated cells. In this study, the bystander ef...
