Membrane systems are taking advantages of their selectivity, high surface area per unit volume, and their potential for controlling the level of contact and/or mixing between two phases. This review presents these various membrane processes by focusing more precisely on membrane materials, module design, operating parameters and the large range of possible applications. Ultrafiltration and microfiltration are well-known membrane separation processes, used i.e. for solvent removal, virus filtration, and antibiotics production. Membrane bioreactors are alternative approaches to classical methods of immobilizing biocatalysts, i.e. for the production of aminoacids, antibiotics, and anti-inflammatories. Chromatographic membranes may replace advantageously conventional resin-based chromatography columns, having the benefit of the absence of the long diffusion times that often occur in resin-based chromatography. Finally, membrane contactors involve using a pressure to force a dispersed phase to permeate through a membrane into a continuous phase, for the preparation of emulsions and various types of particles.</p></div>","PeriodicalId":100733,"journal":{"name":"ITBM-RBM","volume":"27 1","pages":"Pages 1-7"},"PeriodicalIF":0.0,"publicationDate":"2006-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.rbmret.2005.10.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91638079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indeed, installing a medical device within a pressure level much higher than atmospheric pressure and in an oxygen enriched atmosphere is an interesting challenge. In fact, few manufacturers dare engage in this way. Besides, for many years numerous working groups have emerged in hyperbaric medecine. Currently a european standard is being finalized and based on a risk analysis identifying, among other things, a certain number of potential hazards. They can potentially generate dangers during the use of a hyperbaric chamber. Installing a medical device in a hyperbaric chamber is not an easy thing to do. Indeed, the risks induced by a use in a hyperbaric chamber cannot be minimized. Furthermore the medical device must not cause additional risks within the chamber or, anyway, the risks must be evaluated, reduced and accepted. Consequently, prior to installing a medical device, this study proposes a methodology which enables to evaluate the risk management concerning the use of a medical device. Once the methodology completed, the manager of hyperbaric oxygen therapy unit is able to decide whether to install the device or not.</p></div>","PeriodicalId":100733,"journal":{"name":"ITBM-RBM","volume":"26 5","pages":"Pages 363-370"},"PeriodicalIF":0.0,"publicationDate":"2005-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.rbmret.2005.09.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75490663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model of the ventricle includes a description of the electromechanical phenomena occurring during cardiac contraction. It explains the global behaviour of the heart and is coupled with a model of the circulation. The whole cardiovascular system is under the influence of a regulation model. In fact, the cardiovascular system is regulated by the Autonomic Nervous System (ANS). In this work, only the influence of the short-term regulation of blood pressure (the baroreflex) is considered. The model allows the simulation of various physiological tests of the ANS, like the tilt test or the Valsalva manœuvre. These tests are usually used with patients to detect some pathology (syncope for example). But the interpretation of the signals obtained (blood pressure, heart rate) is often difficult because of the complexity of the SCV. It is then possible to improve the comprehension of the interaction between the SCV and the ANS thanks to the model; and to give a physiological interpretation of the signals obtained with the tilt test and the Valsalva manœuvre.</p></div>","PeriodicalId":100733,"journal":{"name":"ITBM-RBM","volume":"26 5","pages":"Pages 333-343"},"PeriodicalIF":0.0,"publicationDate":"2005-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.rbmret.2005.07.004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79517357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
