We show that limit transitions from Askey-Wilson polynomials to q-Racah, little and big q-Jacobi polynomials can be made rigorous on the level of their orthogonality measures in a suitable weak sense. This allows us to derive the orthogonality relations and norm evaluations for the q-Racah polynomials, little and big q-Jacobi polynomials by taking limits in the orthogonality relations and norm ...

Exposure to hexavalent chromium compounds is associated with the risk of lung cancer, dermatitis, gastrointestinal ulcers, and other tissue damages. The aim of this study was to compare liver isoenzyme and total serum activities of aspartate aminotransferase (AST) as cytotoxic biomarkers of acute and chronic cytotoxicity of Cr(VI). We investigated the extent of cell damage caused by chromium(VI...

objectives: diabetes mellitus is associated with biochemical, physiological and pathological alterations in the liver. the aim of this study was to investigate the effects of hydroalcoholic extract of prangos ferulacea (l.) lindle (p.f) on changes in rats´ liver structure and serum activities of alanin and aspartate aminotransferases after alloxan injection. materials and methods: in this study...
