Vyšetření antigenu RhD molekulárně genetickými metodami / RhD antigen screening by molecular genetic methods

Bakerová, Dagmar January 2019 (has links)
Author: Bc. Dagmar Bakerová Supervisor: MUDr. Vít Řeháček Charles University, Faculty of Pharmacy in Hradec Králové Title of diploma thesis: RhD antigen screening by molecular genetic methods This thesis deals with the genotyping of weak and partial antigens using molecular genetic methods. The main aim is to evaluate the rate of the representation of individual types of variant and weak RhD antigens in first-time blood donors, patients and pregnant women. Testing took place at the Transfusion Department of University Hospital Hradec Králové between October 2015 and February 2019. The PCR-SSP method was used for RHD genotyping using commercially supplied BAGene SSP kits from BAGene Health Care. The study includes 32 samples from first-time blood donors in the reference period to determine the specific type of RhD antigen, and 188 samples from patients and pregnant women, for whom serological methods could not be used to unequivocally identify the RhD antigen. For all pregnant women, moreover, the genotyping result was a factor in determining whether to administer anti-D immunoglobulin. This RHD genotyping for all serologically ambiguous samples has made it possible to determine a specific type of partial or weak RhD antigen. In the donor group, the weak RhD antigen was detected in 1.12 % of cases...

Acreditação de laboratórios de ensaio segundo a norma ABNT NBR ISO/IEC 17025

Silva, Vítor Vasata Macchi January 2013 (has links)
Esta dissertação apresenta um estudo que possui como tema central a acreditação segundo a norma ABNT NBR ISO/IEC 17025 e os esforços dispendidos por laboratórios de ensaio e calibração para sua obtenção. O objetivo principal foi facilitar a implantação da norma ABNT NBR ISO/IEC 17025 em laboratórios de ensaio interessados em obter tal reconhecimento. O trabalho foi organizado conforme três artigos. No primeiro, foi estruturado um método de padronização de ensaios que atende aos requisitos da norma vinculados à seleção e validação de métodos e pode auxiliar os laboratórios a obter a acreditação almejada. No segundo, foram propostas diretrizes para criação, estruturação e acreditação de sistemas de gestão da qualidade que visem o atendimento dos requisitos da norma referida. No terceiro, foram identificados os impactos que requisitos listados pela norma ABNT NBR ISO 14971 e pela Resolução da Diretoria Colegiada (RDC) 16 da Anvisa, de 28 de Março de 2013, podem provocar em laboratórios de ensaio e calibração de equipamentos. Os resultados indicaram que são utilizados, predominantemente, critérios quantificáveis nas etapas que compõem o ciclo de vida de métodos de ensaio. Além disto, foi destacado que diretrizes como “treinar envolvidos em ABNT NBR ISO/IEC 17025” e “avaliar o Sistema de Gestão da Qualidade (SGQ) estruturado” podem contribuir para que sejam minimizadas as não conformidades identificadas durante a verificação a ser realizada pelo organismo acreditador. Posteriormente, foi identificado que o desenvolvimento de métodos de ensaio se relaciona diretamente com as demandas dos clientes dos laboratórios. Por fim, foi destacado que as principais dificuldades enfrentadas pelos laboratórios de ensaio e calibração estão relacionadas com a estruturação física e com o processo de estruturação do SGQ desses laboratórios. / This thesis reports a study whose central theme is ABNT NBR ISO/IEC 17025 accreditation, and the efforts to be exerted by testing and calibration laboratories to obtain it. The main objective was to facilitate the implantation of ABNT NBR ISO/IEC 17025 requirements in laboratories which seeks such recognition. The work was organized in terms of three articles. In the first, a test standardization method is described which meets the requirements specified for the selection and validation of methods, and which can help laboratories to obtain the desired accreditation. In the second, guidelines are proposed for the creation, definition of structural form and accreditation of quality management systems set up to meet the specified requirements. The third identifies the impacts which ABNT NBR ISO 14971 and RDC 16 from Anvisa, of 28 March 2013, can have on laboratories that undertake tests and calibration of equipment. The results show that the criteria used in the steps which make up the life-cycles of testing procedures are primarily quantitative. It is also emphasized that meeting requirements such as "training those involved in ABNT NBR ISO/IEC 17025" and "evaluate performance of the structured Quality Management System (QMS)" can contribute by minimizing the occurrence of failures to meet required specifications when the certifying body conducts its assessment. It was also found that the development of testing methods is directly related to the demands of clients served by the laboratories. Lastly, it was found that the main difficulties encountered by testing and calibration laboratories are related to the way in which their QMSs was established, and to their physical structure.

Shear and extensional rheology of hydroxypropyl cellulose melt using capillary rheometry

Paradkar, Anant R, Kelly, Adrian L., Coates, Philip D., York, Peter January 2009 (has links)
No / With increasing interest in hot melt extrusion for preparing polymer-drug systems, knowledge of the shear and extensional rheology of polymers is required for the formulation and process design. Shear and extensional rheology of three commercial grades of hydroxypropyl cellulose (HPC) was examined at 140, 145 and 150 degrees C using twin bore capillary rheometry at range of processing rates. The power law model fitted for shear flow behaviour up to shear strain rates of approximately 1000s(-1), above which measured shear viscosities deviated from the power law and surface instabilities were observed in the extrudate, particularly for higher molecular weight grades. Shear thinning index was found to be relatively independent of temperature and molecular weight, whilst the consistency index, indicative of zero shear viscosity increased exponentially with increase in molecular weight. Extensional viscosity of all grades studied was found to decrease with increasing temperature and increasing processing rate. Foaming of the extrudate occurred especially at low temperatures and with the high molecular weight grade. An understanding of the relationships between shear and extensional flows with temperature, processing rate and molecular weight is a useful tool for process design; optimisation and troubleshooting of Hot melt extrusion (HME) of pharmaceutical formulations.

Wear testing of high-alloy carbon steel used in mining tools

Olsson, Sara, Efsing, Linn January 2013 (has links)
Wear is a commonly occurring degradation mechanism for materials and components in the rock drilling industry. The wear can occur by either abrasion or adhesive wear. Further corrosion and presence of water or other lubricating fluids with or without particles may influence the behavior. Which mechanism, or mechanisms, and under which conditions it occurs, as well as the relative wear rate is dependent on the actual operating conditions for the component. In the present study, commonly available and general test methods for wear on high-alloy carbon steel has been analyzed. The project has been carried out through literature reviews and study visits at the tribology laboratory at KTH and at the Angstroms laboratory at Uppsala University. The present study indicates that it is difficult to suggest a feasible test method that is possible to use for all different situations of the wear that may occur. A test adapted to the actual situation is required to achieve a proper wear rate comparable to the wear rate in a real application.  According to the requirements from Ovako AB, a test that is general, cost effective and can be used when developing steel with higher wear-resistance, following wear testing methods has been compared: a pin-on-disk apparatus, a dry/wet sand/rubber wheel, a dry/wet sand/steel wheel, a tumbling mill, a particle erosion rig, a solid particle impingement using gas jets and a grinding machine. The tumbling mill, the grinder and the “Standard Test Method for Wear Testing with a Pin-On- Disk Apparatus” correspond to the requirements best. Ovako AB is recommended to continue the work with these testing methods. / Nötning är en vanlig mekanism som orsakar nedbrytning på material i gruvindustrin. Nötningen kan förekomma som abrasiv eller adhesiv nötning. Korrosion och närvaro av vatten eller andra smörjande vätskor med eller utan lösa partiklar kan påverka beteendet. Den eller de mekanismer som styr nötningen såväl som nötningstalet beror på de aktuella förhållanden vilka materialet eller materialen verkar i. I denna studie har en generell testmetod för att utvärdera nötning på höglegerat kolstål har undersökts. Arbetet har genomförts genom litteratursökning samt studiebesök vid tribologiska laboratoriet på KTH samt på Ångströmska i Uppsala. Utifrån arbetet har det visat sig att det inte förekommer några generella nötningstest för alla applikationer, då det krävs ett test som är anpassat efter verkligheten för att få ut korrekt nötningstal. Utifrån Ovako ABs önskemål om ett generellt test som är ekonomiskt hållbart samt kan användas för att utveckla nötningsbeständigheten i de stål där nötning förekommer har följande testmetoder jämförts: pinne/skiva-maskin, blött/torrt sand/gummihjul, blött/torrt sand/stålhjul, roterande trumma, ”Erofugen”, partikelsprutare och en slipmaskin. De test som motsvarar kravprofilen bäst är den roterande trumman, slipmaskinen samt den standardiserade pinne/skiva-maskinen. Utifrån dessa testmetoder rekommenderas Ovako AB att fortsätta arbetet.
