Development of a Polyclonal Antibody-based AC-ELISA and Its Comparison with PCR for Diagnosis of Canine Parvovirus Infection

引用

Virologica Sinica 2010年第5期25卷 352-360页

作者： manoj kumar Sukdeb Nandi Sunil Chidri Virology Laboratory Centre for Animal Disease Research and DiagnosisIndian Veterinary Research Institute

A polyclonal antibody-based antigen-capture ELISA （AC-ELISA） has been developed for detection of Canine parvovirus （CPV） antigens in faecal samples of dogs. The assay uses rabbit anti-CPV polyclonal antibody as the capture antibody, guinea pig anti-CPV polyclonal antibody as tracing antibody and anti-guinea pig HRPO conjugate as the detection system. The optimum dilution of the capture antibody and the tracing antibody capable of detecting the CPV-2 antigens was found to be 1：1 600 and 1：400, respectively, in the check-board titration. In this study, a total of 152 samples （129 faecal samples and 23 cell culture supernatant） were tested both by AC-ELISA and by polymerase chain reaction （PCR）. Of the samples tested, 69 and 78 samples were found positive by AC-ELISA and PCR, respectively. The AC-ELISA had relative sensitivity, relative specificity and accuracy of 88.4%, 100.0% and 91.4% respectively. The analytical sensitivity of AC-ELISA was estimated to be 102.8 TCID50/mL whereas PCR sensitivity was 100.8 TCIDs0/mL. The AC-ELISA is a simple, quick and reliable method for screening large numbers of faecal samples of dogs suspected of CPV infection.

With the increasing use of humanoid robots in several sectors of industrial automation and manufacturing, navigation and path planning of humanoids has emerged as one of the most promising area of research. In this paper, a navigational controller has been developed for a humanoid by using fuzzy logic as an intelligent algorithm for avoiding the obstacles present in the environment and reach the desired target position safely. Here, the controller has been designed by careful consideration of the navigational parameters by the help of fuzzy rules. The sensory information regarding obstacle distances and bearing angle towards the target are considered as inputs to the controller and necessary velocities for avoiding the obstacles are obtained as outputs. The working of the controller has been tested on a NAO humanoid robot in V-REP simulation platform. To validate the simulation results, an experimental platform has been designed under laboratory conditions, and experimental analysis has been ***, the results obtained from both the environments are compared against each other with a good agreement between them.

采用带有气体保护装置的TIG自熔焊技术以对接接头结构形式焊接厚度为3 mm的Ti-6Al-4V合金板。在适当热输入条件下获得完全熔透的焊接接头后,结合较高焊接电流和扫描速度以减少热输入开展后续实验。对不同热输入条件下获得的焊接接头进行深入的显微组织分析。结果表明,显微硬度、拉伸强度和断裂强度之间存在强相关性。采用较低的热输入可以显著提高焊接接头的力学性能。这是由于在较低热输入条件下,热输入的变化导致初生α相、初生β相和马氏体α相发生改变,从而改善了焊接接头的力学性能。随着热输入从0.406 k J/mm降低到0.232k J/mm,焊接接头的拉伸强度和断裂强度分别从1020和1015 MPa增加到1070和1950MPa。在最小热输入(0.232k J/mm)的情况下,接头的拉伸强度达到基材的98%。实验结果证明在低热输入条件下TIG焊焊接Ti-6Al-4V合金的潜力。

AIM： To confirm the presence of recombination, fulllength hepatitis B virus （HBV） from chronic patients was sequenced and analyzed. METHODS： Full-length HBV genomes from 12 patients were amplified and sequenced in an automated sequencer. Phylogenetic analysis was carried out on full-length, Core and preS2/Surface regions using MEGA software. SimPIot Boot Scanning and amino acid sequence analysis were performed for confirmation of recombination. RESULTS： Eight patients were infected with genotype D strain; one patient with genotype A and three patients had genotype A and D recombination; two of them had cirrhosis and one had hepatocellular carcinoma. Phylogenetic analysis of core and preS2/surface regions separately showed evidence of genotype A and D recombination. The breakpoints of recombination were found to be at the start of preS2 and at the endof surface coding regions. CONCLUSION： We identified and characterized recombinant A and D genotype HBV in hepatitis B surface antigen （HBsAg）-positive patients.

Relevance of early intervention in Fahr's disease: understanding through a case study

General Psychiatry 2019年第1期32卷 43-45页

作者： Jamshed Ahmad Bandna Gupta Sujita kumar kar Department of Psychiatry King George's Medical UniversityLucknowUttar PradeshIndia

SUMMARY Intracranial calcification may result from disturbances in calcium metabolism. It often remains asymptomatic, but may present with symptoms like seizure and neurological deficits. Correction of the underlying metabolic disturbance before damage of neuronal tissues due to intracranial calcification may be useful in preventing irreversible neurological deficits. This window period may be the crucial period that needs a thorough clinical evaluation and urgent intervention. We highlight the case of an adult woman with Fahr's disease presented with generalised tonic-clonic seizure. The management priorities were also discussed along with review of literature.
