background: pregnant women with previous gestational diabetes mellitus are at increased risk of progressive carotid artery disorders. the current study evaluated carotid intima-media thickness (imt) in pregnant women with gestational diabetes at two time points of mid-term and full-term pregnancy to determine whether gestational diabetes mellitus causes increased imt. methods: this cross-sectio...

background: it is not clear whether the latest activation sites in the left ventricle (lv) are matched with infracted regions in patients with ischemic cardiomyopathy (icm). we aimed to investigate whether the latest activation sites in the lv are in agreement with the region of akinesia in patients with icm.   methods: data were analyzed in 106 patients (age = 60.5 ± 12.1 y, male = 88.7%) with...

introduction: we aimed to investigate of effect of left bundle branch block (lbbb) on perfusion and functional parameters in dipyridamole tc99m-mibi gated myocardial perfusion spect which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 70 patients with low pre-test probability of coronary artery disease in two groups:  35 patients with lbbb and  35 subjects...

catecholamine is a group of neurotransmitters that is believed to be responsible for the normal function of animal brain. physiological and behavioral changes of human body have been reported due to the damage of the brain function following lead exposure. due to the assumption of lead disposal in brain tissue with two year for its half-life, which results in alteration of brain function, we in...

The primary purpose of the present study was to explore whether there was any significant relationship between attitude, self-efficacy, and job satisfaction of Iranian EFL teachers on the one hand, and their choice of teaching strategies. Strategies mostly used by participants of the study with low, mid, and high levels of self-efficacy comprised another purpose of the study. To this end, a que...

Gene identity by descent (IBD) is a fundamental concept that underlies genetically mediated similarities among relatives. Gene IBD is traced through ancestral meioses and is defined relative to founders of a pedigree, or to some time point or mutational origin in the coalescent of a set of extant genes in a population. The random process underlying changes in the patterns of IBD across the geno...

Existing research argues that the muscular male body ideal, often promoted in the media, is associated with male body dissatisfaction and increasingly problematic attempts to attain unrealistic body shape by young males. The present study sought to examine the influence of ‘‘lad magazines”, a highly popular media sector over the last decade, and also the role of dating, or relationship, status,...

We present a simple Monte Carlo method for estimating the age of the most recent common ancestor (MRCA) of a sample of DNA sequences. We show that Templeton's (1993) estimator of the age of the MRCA based on the maximum number of nucleotide differences between two sequences in a sample is inaccurate, and we demonstrate the new method by reanalyzing a sample of DNA sequences from human Y chromos...

A feasibility design study was undertaken to assess the requirements of a mid-infrared echelle spectrograph (MIRES) with a resolving power of 120,000 and its associated mid-infrared adaptive optics (MIRAO) system on the Thirty-Meter Telescope. Our baseline design incorporates a 2Kx2K Si:As array or array mosaic for the spectrograph and a 1Kx1K Si:As array for the slit viewer. Various tradeoffs ...
