OBJECTIVE Strain and strain rate imaging is currently the most popular echocardiographic technique that reveals subclinical myocardial damage. There are currently no available data on this imaging method with regard to assessing right ventricular involvement in anterior myocardial infarction. Therefore, we aimed to evaluate right ventricular regional functions using a derived strain and strain ...

In this paper, accumulation of plastic deformation of AISI 1045 steel plates with circular cutouts under cyclic axial loading is studied. Loading was applied under force-control conditions. Experimental tests were performed using a Zwick/Roell servo hydraulic machine. Under force-control loading with nonzero mean force, plastic strain was accumulated in continuous cycles called ratcheting. Nume...

PURPOSE As cardiomyopathy is more prevalent and currently the leading cause of death in Duchenne muscular dystrophy (DMD), early detection of myocardial involvement is important. The purpose of this study was to analyze myocardial strain in DMD children, for the possibility of early detection of myocardial dysfunction. MATERIALS AND METHODS We reviewed medical records of DMD patients who were...

A strain of Absidia fusca was isolated from a pesticidecontaminated soil (Annaba, Algeria). The biotransformation capability of this strain towards two polycyclic aromatic hydrocarbons (PAHs): anthracene and fluoranthene was compared to that exhibited by another strain of A. fusca isolated from a noncontaminated milieu and considered as a control. The results obtained were statistically analyze...

The virulence of Pasteurella multocida (P. multocida) serotype A1 for chickens and mice was determined. Groups of chicken and mice were exposed intramuscularly and intraperitoneally to various concentration of P. multocida broth culture, respectively. This strain was highly virulent for chickens so that those exposed to only 7 c.f.u. of the organism died in less than 24 hours. Groups of mice ex...

Hairy root induction in plants has affected by many factors including type, age of explant and bacterial strain. In the present study, the effects of bacterial strains (A4, C58, 15834 and GM), two concentrations (OD600= 0.5 and 1) and two explants (leaves and stems) in hairy root induction of C. blumei</...

In an Escherichia coli strain lysogenic for lambda spc2 transducing phage, an extra copy of ribosomal protein (r-protein) genes in the spc and alpha operons are carried on the phage chromosome. Expression of genes in the spc operon in this merodiploid strain was compared with that in a control "haploid" strain carrying lambda trkA phage. It was found that the synthesis rate of spc mRNA, relativ...

The authors examined how dispute-related stressors predicted strain experienced by third parties (N = 270) and their perceptions of a potential strike by part-time faculty. Immediately preceding a strike deadline, the authors surveyed students on their support for the union, perceived fairness, perceived effects of the impending strike, and perceived control. The authors also measured perceptio...

Postreplication repair has been studied in ultraviolet light (UV)-irradiated fibroblast strains derived from eight apparently normal control donors and seven xeroderma pigmentosum patients. One control donor strain had an intermediate defect in postreplication repair similar to that in excision-deficient xeroderma pigmentosum fibroblasts. However, unlike the xeroderma pigmentosum strains, this ...
