Sectional Anatomy Quiz-VII

This series involves a quiz pertaining to the identification of key anatomical landmarks and normal structures present at a given level on the computed tomography (CT) image. The current quiz demonstrates examples of normal and abnormal axial CT images at the level of origin of the coeliac artery. The representative image is subsequently followed by further images demonstrating various commonly encountered pathologies found at this level in clinical practice. In each image, readers are expected to identify highlighted anatomical structures and appreciate how given pathologies can alter the appearance of normal structures. This series aims to advance understanding of sectional anatomy and aid nuclear physicians in the interpretation of the CT component of single photon emission computed tomography (SPECT) and positron emission tomography (PET) studies

Methodologies and tools for OSS: current state of the practice

Over the years, the Open Source Software (OSS) development has matured and strengthened, building on some established methodologies and tools. An understanding of the current state of the practice, however, is still lacking. This paper presents the results of a survey of the OSS developer community with a view to gain insight of peer review, testing and release management practices, along with the current tool sets used for testing, debugging and, build and release management. Such an insight is important to appreciate the obstacles to overcome to introduce certification and more rigour into the development process. It is hoped that the results of this survey will initiate a useful discussion and allow the community to identify further process improvement opportunities for producing better quality software

Experimental Investigation of the Effects of Hydrogen Addition with Diesel on Performance and Emission of a Single Cylinder Diesel Engine

Need of the hour in present day scenario is to cope with energy crisis and human life in India and around the globe which is associated with depletion in the percentage of petroleum products and increase in the share of pollution caused due to emissions from diesel operated engines. This work tries to address these two major concern with the use of alternative fuel for diesel engine .A lot of research is going on the use of alternative and innovative fuels in the word, among those one of the most promising alternative ought to be hydrogen for being a clean and non carbon in nature. However various ongoing researches shown hydrogen blending to be proved to show positive effect on performance and emission of a diesel engine, which has to be carried forwarded. In this work a flow rate of 4 lpm, 6 lpm and 8 lpm respectively blend of hydrogen proportion where used along which diesel at loading at a constant speed of 1500 rpm to determine various engine performance parameters such as brake thermal efficiency, brake specific fuel consumption ,brake power, indicated thermal efficiency, mechanical efficiency, volumetric efficiency, torque output and power output. along with these various emission parameters such as percentage of CO,HC ,NOx gas temperature with varying blend proportion are also observed and compared

Identification and management of atypical Hemolytic Uremic Syndrome immediately post heart transplantation

Atypical hemolytic uremic syndrome (aHUS) is a serious hematologic disorder with high mortality if left untreated. A comprehensive literature review revealed only two cases of aHUS post–heart transplantation. In both cases the disease developed after induction of calcineurin inhibitor therapy. We report a case of immediate post–heart transplantation aHUS, manifested before the induction of, and therefore not associated with, calcineurin inhibitor

Homogeneous Gold Catalysis through Relativistic Effects: Addition of Water to Propyne

In the catalytic addition of water to propyne the Au(III) catalyst is not stable under non-relativistic conditions and dissociates into a Au(I) compound and Cl2. This implies that one link in the chain of events in the catalytic cycle is broken and relativity may well be seen as the reason why Au(III) compounds are effective catalysts.Comment: 12 pages, 3 figures, 1 tabl

The Potential Value of EGFR and P53 Immunostaining in Tumors of the Urinary Bladder

The expression of EGFR and p53 has not been adequately studied as a prognostic tool in urinary bladder tumors. We analyzed 74 bladder cancer samples from Egypt for EGFR and p53 expression using immunohistochemistry. The tumors were of different histological types, grades and clinical stages, and with established lymph node status. Almost 61% of the tumors showed positive membranous EGFR expression and 74.3% had positive nuclear staining of p53. Analysis of correlation of the IHC staining with clinical variables showed a significant correlation only between EGFR expression and histological type (p=0.002, ANOVA), in that the expression was higher in squamous cell carcinomas than in other histological types. There were no significant correlations between p53 or EGFR with the other clinicopathological variables, including age, sex, staging, grading, and lymph node status. Further studies are needed to determine if EGFR and p53 might be used as prognostic tools in bladder cancer

Sensory hypoinnervation in club foot

Abstract We have compared the density of nerve fibres in the synovium in club foot with that of specimens obtained from the synovium of the hip at operations for developmental dysplasia. The study focused on the sensory neuropeptides substance P; calcitonin gene-related peptide; protein gene product 9.5, a general marker for mature peripheral nerve fibres; and growth associated protein 43, a neuronal marker for new or regenerating nerve fibres. In order to establish whether there might be any inherent difference we analysed the density of calcitonin gene-related peptide-positive nerve fibres in the hip and ankle joints in young rats. Semi-quantitative analysis showed a significant reduction in the number of sensory and mature nerve fibres in the synovium in club foot compared with the control hips. Calcitonin gene-related peptide (CGRP) positive fibres were reduced by 28%, substance P-positive fibres by 36% and protein gene product 9.5-positive fibres by 52% in club foot. The growth associated protein 43-positive fibres also seemed to be less in six samples of club foot. No difference in the density of CGRP-positive nerve fibres was observed in the synovium between ankle and hip joints in rats. The lack of sensory input may be responsible for the fibrosis and soft-tissue contractures associated with idiopathic club foot

This project was initiated to better understand medical trainee perspectives on training and providing healthcare services to prison populations at one AMC specializing in the care of incarcerated patients: The University of Texas Medical Branch at Galveston (UTMB). We set out to characterize the attitudes and perceptions of medical trainees from the start of their training until the final year of Internal Medicine residency. Our goal was to analyze medical trainee perspectives on caring for incarcerated patients and to determine what specialized education and training is needed, if any, for the provision of ethical and appropriate healthcare to incarcerated patients. Results We found that medical trainees grapple with being beneficiaries of a state and institutional power structure that exploits the neglected health of incarcerated patients for the benefit of medical education and research. The benefits include the training opportunities afforded by the advanced pathologies suffered by persons who are incarcerated, an institutional culture that generally allowed students more freedom to practice their skills on incarcerated patients as compared to free-world patients, and an easy compliance of incarcerated patients likely conditioned by their neglect. Most trainees failed to recognize the extreme power differential between provider and patient that facilitates such freedom. Conclusions Using a critical prison studies/Foucauldian theoretical framework, we identified how the provision/withholding of healthcare to and from persons who are incarcerated plays a major role in disciplining incarcerated bodies into becoming compliant medical patients and research subjects, complacent with and even grateful for delayed care, delivered sometimes below the standard best practices. Specialized vulnerable-population training is sorely needed for both medical trainees and attending physicians in order to not further contribute to this exploitation of incarcerated patients.The University of Kansas (KU) One University Open Access Author Fun
