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...

Abstract The Twakputs Gneiss is a garnetiferous, K-feldspar megacrystic, biotite granite-granodiorite orthogneiss. It represents major unit in the Kakamas Domain of Mesoproterozoic Namaqua-Natal Metamorphic Province extending about 250 km between Riemvasmaak South Africa and Grünau southern Namibia. occurs as foliation-parallel, sheet-like bodies tightly infolded together with granulite-facies ...

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 ...

     Periodic vegetation patterns (PVPs) are striking features of many global drylands. Although they have attracted wide research study, resulting in many hypotheses, their origin and controlling factors remain unresolved. Theoretical works dominate a large literature seeking to account for the occurrence and properties of PVPs, especially banded vegetation patterns (‘tiger bush’). In light of...

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 ...
