Research ArticleOpen accessIn the keywordsEvaluation of the Severity of Mitral Valvular Regurgitation with Doppler Echocardiography Using Proximal Flow Convergence MethodPinjari Abdul Khayum, M.N. Giriprasad, P.V. SrideviProblem statement: Valvular regurgitation is recognized as the central cause of morbidity and mortality. Even though the clinician can detect the presence of regurgitation by mere physical examination; diagnostic methods become inevitable while estimating the severity of valvular regurgitation and in the transformation of cardiac chambers as in reaction to the volume overload condition. Lately, a promising new technology, the … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,220 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Putative Serine protease from Larval Midgut of Red Palm Weevil Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae): Partial Purification and Biochemical CharacterizationAhmed Al Jabr, Mahmoud Abo-El-SaadA putative serine protease was isolated and partially purified from larval midgut of red palm weevil (RPW), Rhynchophorus ferrugineus (Olivier) using anion exchange chromatography, DE-52. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) of this protease showed that the major band has a molecular weight of approximately 24 kDa corresponding to the same molecular weight of mammalian trypsin.
