Research ArticleOpen accessIn the abstractExpression of the CD44 Protein in the Heart Valves Affected with Rheumatic Heart DiseaseR. Vijayalakshmi, S. Nayar, K.M. CherianProblem statement: The primary aim was to study the expression of CD44 protein in the heart valves removed surgically for either stenosis or regurgitation and to study the morphology of valves using histochemical staining. Approach: We studied 107 valves which were collected from the International Centre for Cardio Thoracic and Vascular Diseases. Results: Aortic and mitral valves were obtained from … …American Journal of Infectious Diseases, Vol. 6, Issue 4 · 31 Dec 2010 · 7,406 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparison of Tuberculin Skin Test and Interferon Gamma Assay for the Diagnosis Latent TuberculosisAbolfazl Poorhasan, Mehdi Haghdoost, Omid MashrabiProblem statement: After HIV infection, TB is the most common cause of mortality due to a single infectious agent.

Research ArticleOpen accessIn the abstractProperties of Absolute Stability in the Presence of Time LagsM. De la Sen, J. L. Malaina, A. Gallego, J. C. SotoThis study is concerned with the properties of absolute stability independent of the delays of time-delay systems, possessing non commensurate internal point delays, for any nonlinearity satisfying a Popov’s- type time positivity inequality. That property holds if an associate delay-free system is absolutely stable and the size of the delayed dynamics is sufficiently small. The results are obtained for nonlinearities … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,569 accessesView PDF Cite
