Abstract: Ulcerative colitis is considered frequent in majority of European and North American population and exceptional in most of the developing Asian countries. There is a dearth of reported data from South India on the incidence of the disease and its prevalence. Hence the present study was designed to estimate the prevalence of ulcerative colitis in a tertiary care hospital of Hyderabad, South India. The study population consisted of 157 Ulcerative colitis and 204 healthy subjects. All subjects were interviewed by means of a questionnaire for general demographical details and socioeconomic conditions, health related quality of life and history of UC. Patients were categorized based on disease severity; moderate: 95, and severe: 62 and disease manifestation: 73 (46.5%) pancolitis, 60 (38.2%) left-sided colitis and 24 (15.3%) had proctosigmoiditits. Disease prevalence was high in patients of <35 years age. Junk/outside food consumers were significantly high in Ulcerative colitis than controls 68 (43.3%) vs 67 (32.8%) p = 0.048. There was no significant difference of disease prevalence with diet, drinking habits and alcoholic consumption. Whereas UC prevalence was high in nonsmokers than smokers (p = 0.025). This report establishes the importance of various factors in ulcerative colitis. This is the first population based study from South India that reports the prevalence of ulcerative colitis. Ulcerative colitis is more predominant in young age. Further, junk food consumers and Non-smokers/ex-smokers were found to be high in terms of UC prevalence.
Primary sclerosing cholangitis and Biliary cirrhosis associated with Ulcerative colitis

Journal of Medical and Allied Sciences , 2011,
Abstract: Primary sclerosing cholangitis and Ulcerative colitis are caused by progressive inflammation of the bile duct and large intestine respectively. The existence of any plausible association between Primary sclerosing cholangitis and Ulcerative colitis remains highly elusive. Little is known about the incidence and prevalence of primary sclerosing cholangitis with concomitant Ulcerative colitis in the Indian subcontinent. We report a case of Primary sclerosing cholangitis with long standing Ulcerative colitis which later also developed Primary biliary cirrhosis.
Las competencias del profesorado en el entorno CDIO

REDU : Revista de Docencia Universitaria , 2012,
Abstract: La iniciativa CDIO (Concebir-Dise ar-Implementar-Operar) es un entorno cooperativo nacido en el MIT y las universidades suecas de Chalmers, Linkoping y KTH en el que actualmente participan más de 80 instituciones de más de 25 países. Define un marco educativo innovador para la formación en ingeniería. En el marco CDIO se promueve el aprendizaje de las bases fundamentales y los contenidos disciplinares avanzados de la ingeniería, en un entorno con referencias claras al ejercicio profesional de la ingen iería como contexto adecuado para su aprendizaje. El conjunto de competencias definido por la iniciativa CDIO (el CDIO Syllabus) se distingue de otros listados de competencias por su amplitud, grado de concreción y por el hecho de incluir no sólo competencias genéricas, personales e interpersonales, que pueden corresponder a cualquier disciplina, sino también las que se han identificado como propias de la ingeniería, y que corresponden a las habilidades necesarias para desarrollar productos y sistemas complejos en un entorno cooperativo. CDIO define también 12 estándares que facilitan el dise o de planes de estudio que incorporen dichas competencias. Por lo que respecta a las competencias del profesorado, objeto de este artículo, dos de los estándares hablan específicamente de la necesidad de formar al profesorado para la adquisición de dichas competencias y de la capacidad para transmitirlas (estándar 9) y también de la adopción de metodologías activas que permitan una integración efectiva de los contenidos y las competencias (estándar 10). Mientras que las competencias genéricas personales e interpersonales están adecuadamente cubiertas por los programas de formación del profesorado, las más específicas de la ingeniería precisan de una mayor interacción con la industria e incluso de mecanismos que proporcionen experiencias profesionales reales al profesorado. ABSTRACT Faculty teaching skills in the CDIO initiative The CDIO initiative (Conceive-Design-Implement-Operate) is a collaborative framework initially created by the MIT and the Swedish universities of Chalmers, KTH and Linkoping. Over 80 institutions from over 25 countries are currently involved in CDIO. The initiative defines an innovative educational framework for engineering education. CDIO promotes learning the fundamentals and advanced disciplinary contents of engineering in a context with clear references to the practice of engineering. The set of skills defined by the CDIO initiative (the CDIO Syllabus) differs from other listings of skills due to its size, its depth in specification and th

Abstract: the population of india harbors one of the world's most highly diverse gene pools, owing to the influx of successive waves of immigrants over regular periods in time. several phylogenetic studies involving mitochondrial dna and y chromosomal variation have demonstrated europeans to have been the first settlers in india. nevertheless, certain controversy exists, due to the support given to the thesis that colonization was by the austro-asiatic group, prior to the europeans. thus, the aim was to investigate pre-historic colonization of india by anatomically modern humans, using conserved stretches of five amino acid (epiya) sequences in the caga gene of helicobacter pylori. simultaneously, the existence of a pathogenic relationship of tyrosine phosphorylation motifs (tpms), in 32 h. pylori strains isolated from subjects with several forms of gastric diseases, was also explored. high resolution sequence analysis of the above described genes was performed. the nucleotide sequences obtained were translated into amino acids using mega (version 4.0) software for epiya. an mj-network was constructed for obtaining tpm haplotypes by using network (version 4.5) software. the findings of the study suggest that indian h. pylori strains share a common ancestry with europeans. no specific association of haplotypes with the outcome of disease was revealed through additional network analysis of tpms.
A Dual Fast and Slow Feature Interaction in Biologically Inspired Visual Recognition of Human Action
Bardia Yousefi,C. K. Loo
Computer Science , 2015,
Abstract: Computational neuroscience studies that have examined human visual system through functional magnetic resonance imaging (fMRI) have identified a model where the mammalian brain pursues two distinct pathways (for recognition of biological movement tasks). In the brain, dorsal stream analyzes the information of motion (optical flow), which is the fast features, and ventral stream (form pathway) analyzes form information (through active basis model based incremental slow feature analysis ) as slow features. The proposed approach suggests the motion perception of the human visual system composes of fast and slow feature interactions that identifies biological movements. Form features in the visual system biologically follows the application of active basis model with incremental slow feature analysis for the extraction of the slowest form features of human objects movements in the ventral stream. Applying incremental slow feature analysis provides an opportunity to use the action prototypes. To extract the slowest features episodic observation is required but the fast features updates the processing of motion information in every frames. Experimental results have shown promising accuracy for the proposed model and good performance with two datasets (KTH and Weizmann).
Bio-Inspired Human Action Recognition using Hybrid Max-Product Neuro-Fuzzy Classifier and Quantum-Behaved PSO
Bardia Yousefi,Chu Kiong Loo
Computer Science , 2015,
Abstract: Studies on computational neuroscience through functional magnetic resonance imaging (fMRI) and following biological inspired system stated that human action recognition in the brain of mammalian leads two distinct pathways in the model, which are specialized for analysis of motion (optic flow) and form information. Principally, we have defined a novel and robust form features applying active basis model as form extractor in form pathway in the biological inspired model. An unbalanced synergetic neural net-work classifies shapes and structures of human objects along with tuning its attention parameter by quantum particle swarm optimization (QPSO) via initiation of Centroidal Voronoi Tessellations. These tools utilized and justified as strong tools for following biological system model in form pathway. But the final decision has done by combination of ultimate outcomes of both pathways via fuzzy inference which increases novality of proposed model. Combination of these two brain pathways is done by considering each feature sets in Gaussian membership functions with fuzzy product inference method. Two configurations have been proposed for form pathway: applying multi-prototype human action templates using two time synergetic neural network for obtaining uniform template regarding each actions, and second scenario that it uses abstracting human action in four key-frames. Experimental results showed promising accuracy performance on different datasets (KTH and Weizmann).

Abstract: We report total ten isolates of F. semitectum recovered from different hosts. Identity of these isolates was determined by morphological and cultural characteristics and confirmed by RAPD-PCR analysis using forty random primers. Morphologically all the ten isolates showed similarity, but based on RAPD-PCR analysis, these isolates can be categorized in three groups depending upon similarity co-efficient. Genetic similarity coefficients between pair wise isolates varied from 0.00 to 1.95 based on an unweighted paired group method of arithmetic average (UPGMA) cluster analysis. RAPD-PCR technique can be used as an important tool for the genetic differentiation among isolates of F. semitectum.

Avinash Daga, Smita Sharma
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.312238
Abstract: The equilibrium crystal structure parameter and bulk modulus of the SrMoO3 perovskite has been calculated with ab-initio method based on density functional theory (DFT) using both local density approximation (LDA) and generalized gradient approximation (GGA). The corresponding total free energy along with its various components for SrMoO3 was obtained. The lattice parameter and bulk modulus calculated for SrMoO3 within LDA are 3.99 A and 143.025 GPa respectively whereas within GGA are 4.04 A and 146.14 GPa respectively, both agree well with the available experimental data. The total energy calculated within LDA and GGA is almost the same however lower results are obtained for GGA. All calculations have been carried out using ABINIT computer code.

International Journal of Pharmacology , 2005,
Abstract: Fistulas, occurring in about 20 to 40% of Crohn’s disease patients, are usually resistant to conventional therapy of CD. Biologic therapies, which have revolutionary beneficial effects on diseases with an immunologic background, are a new horizon in treating fistulizing CD. The aim of this study was to evaluate the efficacy of biologic agents used to treat fistulizing CD after a brief overview on epidemiology and pathophysiology of fistulizing CD and definition of biologic therapy. Also it focuses on the trials and adverse effects of the biologic agents proved to be effective (Infliximab and CDP571).

Journal of Biomaterials and Nanobiotechnology (JBNB) , 2011, DOI: 10.4236/jbnb.2011.24050
Abstract: The ability to precisely control the size of semiconductor nanocrystals can create an opportunity for producing functional materials with new properties, which are of importance to applications such as Light emitting diodes, biomedical diagnosis, solar cells, and spintronics. And size of nanoparticle can be controlled with efficient capping agent. For the same purpose we reported, two types of capping, one will lead to nanomatrix and other to Shelled nanostructures. Enhancement in emission intensity observed with Shell nanostructures compare to matrix. PVP is used to control the particle size, to prevent agglomeration and making thin films. A blue shift in energy level at the nanoscale is demonstrated by optical absorption. Electron microscopy studies with an SEM and TEM show a particle size of 10 nm and 15 nm. We also investigated the particle size distribution of nanoparticles by small angle scattering (SAXS) study.
