OBJECTIVES This study sought to examine the role of Nox2 in the contractile dysfunction associated with pressure-overload left ventricular hypertrophy (LVH). BACKGROUND Reactive oxygen species (ROS) production is implicated in the pathophysiology of LVH. The nicotinamide adenosine dinucleotide phosphate oxidase isoform, Nox2, is pivotally involved in angiotensin II-induced hypertrophy but is ...

The development of myocardial fibrosis as a result of cardiac hypertrophy was studied in 11 cats in which the pulmonary artery was banded, six rabbits in which the ascending aorta was banded, and eight cats with various congenital cardiac anomalies. Histological examination of the myocardium revealed multifocal areas of degeneration and necrosis with healing by fibrosis in the right ventricle o...

Abstract. If A is a banded matrix with a banded inverse, then A = BC = F1 . . . FN is a product of block-diagonal matrices. We review this factorization, in which the Fi are tridiagonal and N is independent of the matrix size. For a permutation with bandwidth w, each Fi exchanges disjoint pairs of neighbors and N < 2w. This paper begins the extension to infinite matrices. For doubly infinite pe...

b a ckground: the brown-banded cockroach, supella longipalpa is known as a carrier of pathogenic bacteria in urban environments, but its role is not well documented regarding the carriage of antibiotic-resistant pathogenic bacte- ria in iran. the aim of this study was to determine the resistance bacteria isolated from the brown-banded cockroach in ahvaz, south west of iran. m e t hods: totally ...

Abstract Subtropical grasslands are highly susceptible to habitat conversion and number among South America’s most threatened ecosystems. The of northeastern Argentina have been identified as a priority conservation area for capuchino seedeaters because they constitute the main breeding these migratory birds. Iberá Seedeater (Sporophila iberaensis) is newly described species in Wetlands whose b...

Starch gel electrophoresis was used for examining the transferrin gene locus (Tf) and two esterase gene loci (Est-1 and Est-D1) of a pirarucu (Arapaima gigas) population sample collected from Santa Cruz Lake, Tefé River, Amazonas, Brazil. The Tf locus was tentatively classified as being polymorphic, showing two double-banded patterns (Tf(12) and Tf(22)) of the three theoretically expected ones ...

An a priori analysis of subfilter-scale (SFS) species structure important to estimate chemical reaction rates in large-eddy simulation (LES) is performed using direct numerical (DNS) turbulent premixed flame at turbulence Reynolds number Re0=329 and Karlovitz Ka0=7.23 with semi-detailed finite-rate chemistry. Differences between the complete extracted from DNS those estimated LES-filtered varia...

Matched asymptotic solutions for the steady banded flow of the diffusive Johnson-Segalman model in various geometries ⋆ Abstract We present analytic solutions for steady flow of the Johnson-Segalman (JS) model with a diffusion term in various geometries and under controlled strain rate conditions , using matched asymptotic expansions. The diffusion term represents a singular perturbation that l...

We present a software toolbox for symmetric band reduction, together with a set of testing and timing drivers. The toolbox contains routines for the reduction of full symmetric matrices to banded form and the reduction of banded matrices to narrower banded or tridiagonal form, with optional accumulation of the orthogonal transformations, as well as repacking routines for storage rearrangement. ...
