Eficácia de um novo índice de nocicepção na avaliação da dor no pós-operatório ...

Auditoria à prática profilática e incidência de náuseas e vómitos pós-operatóri...

Introdução: As NVPO são uma das principais queixas dos doentes do pós-operatório. Este trabalho teve como objetivo registar a prática farmacológica para profilaxia de NVPO em cirurgia programada e avaliar a sua eficácia. Metodologia: Incluídos todos os doentes submetidos a cirurgia programada das especialidades de Cirurgia Geral, Urologia e Cirurgia Vascular entre 3 e 21 de Dezembro de 2012. Excluídos se alta...

Influence of volumetric oxygen transfer coefficient (kLa) on xylanases batch pr...

Oxygenation is an important parameter involved in the design and operation of mixing-sparging bioreactors and it can be analyzed by means of the oxygen mass transfer coefficient (kLa). In this study, batch fermentations in stirred tank bioreactor (STB) and airlift bioreactor (ALB) were operated under a range of kLa values, in attempts to optimize and compare the activities of extracellular xylanase and β-xylosi...

Development of a quasi-dry electrode for EEG recording

The present work reports on the development of a novel polymer-based electrode prototype for electroencephalography (EEG). The new electrode concept lies between the classic “wet” and “dry” electrodes, allowing addressing most of their drawbacks, while keeping the advantages of both. A localized skin hydration effect at the electrode/scalp contact point is achieved by the release of a small amount of a moisturi...

Chemopreventive Efficacy of Atorvastatin against Nitrosamine-Induced Rat Bladde...

To investigate the anti-carcinogenic effects of Atorvastatin (Atorva) on a rat bladder carcinogenesis model with N-butyl-N-(4-hydroxibutil)nitrosamine (BBN), four male Wistar rat groups were studied: (1) Control: vehicle; (2) Atorva: 3 mg/kg bw/day; (3) Carcinogen: BBN (0.05%); (4) Preventive Atorva: 3 mg/kg bw/day Atorva + BBN. A two phase protocol was used, in which the drug and the carcinogen were given betw...

Smart RTD for multiphase flow systems

A relatively new concept is presented for evaluation of the fluid age distribution a = a(x,t) within the interior of an apparatus. In the standard RTD approach, the tracer study is performed and the residence time distribution is obtained. In the new approach denoted as SRTD, the fluid age is considered as the field quantity and the governing equation is formulated for its spatio-temporal distribution within th...

Electrochemical methods for speciation of trace elements in marine waters. Dyna...

The contribution of electrochemical methods to the knowledge of dynamic speciation of toxic trace elements in marine waters is critically reviewed. Due to the importance of dynamic considerations in the interpretation of the electrochemical signal, the principles and recent developments of kinetic features in the interconversion of metal complex species will be presented. As dynamic electrochemical methods, onl...

Surgical complications in 2000 renal transplants

INTRODUCTION: Renal transplantation is the best treatment for end-stage renal disease. In the last years, we have seen improvements in immunosuppressive treatment, which have allowed patients to experience a better quality of life and graft survival. Nevertheless, surgical complications remain important problems that increase morbidity, mortality, costs, and hospitalization. Our purpose was to evaluate surgical...
