Biomedical applications of polypeptide multilayer nanofilms and microcapsules

The past few years have witnessed considerable growth in synthetic polymer chemistry and physics, biomaterials science, and nano-scale engineering. Research on polypeptide multilayer films, coatings, and microcapsules is located at the intersection of these areas and are promising materials for applications in medicine, biotechnology, environmental science. Most envisioned applications of polypeptide multilayers have a biomedical bent. This dissertation on polypeptide multilayer film applications covers key points of polypeptides as materials, means of polymer production, film preparation, film characterization methods, and key points of current research in basic science. Both commercial and designed peptides have been used to fabricate films for in-vitro applications such as antimicrobial coatings and cell culture coatings and also microcapsules for drug delivery applications. Other areas of product development include artificial red blood cells, anisotropic coatings, enantioselective membranes, and artificial viruses

Design and fabrication of a data logger for atmospheric pressure, temperature and relative humidity for gas-filled detector development

A novel instrument has been developed to monitor and record the ambient pa- rameters such as temperature, atmospheric pressure and relative humidity. These parameters are very essential for understanding the characteristics such as gain of gas filled detectors like Gas Electron Multiplier (GEM) and Multi Wire Propor- tional Counter (MWPC). In this article the details of the design, fabrication and operation processes of the device has been presented.Comment: 11 pages, 12 figure

Current Concepts in the Management of Postoperative Nausea and Vomiting

Postoperative nausea and vomiting (PONV) are still common following surgery. This is not only distressing to the patient, but increases costs. The thorough understanding of the mechanism of nausea and vomiting and a careful assessment of risk factors provide a rationale for appropriate management of PONV. Strategy to reduce baseline risk and the adoption of a multimodal approach will most likely ensure success in the management of PONV

Comparative Studies On Man-biting Population Of Filarial Vector Cx. Quinquefasciatus (Diptera: Culicidae) Between Tribal And Non-tribal Areas Of Bankura District, West Bengal India

West Bengal, India is endemic for filariasis and the number of patients infected with bancroftian filariasis is increasing. There are no observation on the potential vector of filariasis from the tribal areas that make up considerable part in this state. This study investigate population of Cx. quinquefasciatus in tribal and non-tribal areas of Bankura district. Species composition of mosquitoes, per man-hour density, hourly densities of night biting Cx. quinquefasciatus, number of Cx. quinquefasciatus biting per man per day and per man per night. Preferential biting site and peak period of filarial transmission were recorded from both the study areas. Infection rate, infectivity rate of man-landing vector population and annual transmission potential were observed to be 0.31%, 0.00% and 0.00 in tribal areas and 0.73%, 0.23% and 359.71 in non-tribal areas respectively
