Research ArticleOpen accessIn the abstractEvaluation 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 abstractHistological Features and ki-67 Index In Cervical Atypical LesionsD. Cabibi, L. Giovannelli, M. Cacciatore et al.One of the most frequent challenges in routine diagnostic assessment of cervical biopsies consists of some lesions in which histological features of HPV infection are either inconsistently present or only mildly/focally evident. We named them Atypical Lesions (AL) because differential diagnosis with metaplastic/reactive lesions and LSIL is difficult. It would be important to identify among them those lesions that are … …American Journal of Infectious Diseases, Vol. 4, Issue 3 · 30 Sep 2008 · 7,231 accessesView PDFCite
Research ArticleOpen accessIn the abstractCost Analysis of A System with Preventive Maintenance by Using the Kolmogorov’s Forward Equations MethodKhaled Moh. El-SaidThis study deals with cost analysis of a two- unit cold standby redundant system with preventive maintenance.The random failure occurs at random times which follow an exponential distribution and also the repair time are assumed to be exponentially distributed. Using the Kolmogorov’s forward equations method. Several reliability characteristics are obtained. The mean time to system failure (MTSF) and the profit … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,063 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormetic Interventions in AgingSuresh I.S. RattanSingle or multiple exposure to low doses of potentially harmful agents can have a variety of anti-aging and longevity-extending hormetic effects. These hormetic stressors include irradiation, physical activity, food limitation, heat, hypergravity, dietary components and reactive oxygen species. Molecular mechanisms facilitating the hormetic effects are being elucidated and comprise a cascade of stress response and maintenance and repair pathways. Although … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,831 accessesView PDFCite
Research ArticleOpen accessIn the abstractCorrelation Between MMP-3, TIMP-3 Expression and Neuronal Apoptosis After Ischemia -Reperfusion Injury in RatesZi Xiaohong, Mutasem Abuhamed, Yuan Yi et al.Matrix metalloproteinases (MMPs) play a central role in many biological processes, such as embryogenesis, normal tissue remodeling, wound healing, and angiogenesis. How MMP3, TIMP3 expression and neuronal apoptosis (Fas, Fas-L and Bcl) may provide detrimental or beneficial actions during the injury and repair processes after cerebral ischemia-reperfusion injury in rates was studied. Adult rats underwent middle cerebral artery occlusion (MCAO) … …American Journal of Immunology, Vol. 3, Issue 2 · 30 Nov 2007 · 7,175 accessesView PDFCite
Research ArticleOpen accessIn the abstractStochastic Analysis of a Compound Redundant System Involving Human FailureRitu Gupta, S. K. Mittal, C. M. BatraThis study deals with a compound standby redundant system consisting of three sub-systems A, B, and C connected in series. The sub-system B consists of one main unit and the other is its standby redundant unit. These units further consist of two sub-units connected in series. The sub - units of main unit are connected to sub-units of standby unit … …Journal of Mathematics and Statistics, Vol. 2, Issue 3 · 30 Sep 2006 · 6,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioceramics for Tissue Engineering Applications-A ReviewSunho Oh, Namsik Oh, Mark Appleford, Joo L. OngThree dimensional (3-D) scaffolds have been explored in an attempt to persuade the body to heal or repair tissues that do not do so spontaneously. Considerable advances in tissue engineering and regeneration have been accomplished over the last decade. However, the material and 3-D scaffolds ideal for optimal regeneration of missing or lost tissues has not been identified. While current … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 10,420 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial Distribution and Evaluation of Heavy Metal Pollution in Soil Based on Three-Dimensional Model and Kriging InterpolationBaoshun Liu, Yonghong Zhang, Jun Yao, Jian SuSoil heavy metal pollution is an important content for soil environmental governance. Based on the three-Dimensional (3D) geological modeling technology and ordinary Kriging method, this study described and analyzed the soil pollution status and spatial distribution characteristics of a site in Zhongshan, Guangxi. The results showed that combining 3D geological model and the Kriging interpolation method can well evaluate soil … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 2 · 10 Jun 2022 · 6,144 accessesView PDFCite
Research ArticleOpen accessIn the abstractAgricultural Mechanization in Niger: What Role do Animals Play?Warouma Arifa, Chaibou Mahamadou, Saley Adamou LaoualiThe intensification of agriculture through the use of animal energy has been used since colonial times. This study aims to analyze the level of mechanization in Niger while relying on the role played by animals used for farming in the regions of Maradi and Zinder (Niger Republic). Data collection was carried out between June and August 2020, using a questionnaire … …American Journal of Applied Sciences, Vol. 19, Issue 1 · 7 Feb 2022 · 6,947 accessesView PDFCite
