Development of image analysis methodologies to quantify intracellular PHA, poly...

In wastewater treatment plants (WWTP), enhanced biological phosphorus removal (EBPR) processes are performed by mixed cultures containing polyphosphate (PAO) and glycogen accumulating organisms (GAO). In these processes, it is of crucial importance to monitor the intracellular metabolism, namely glycogen, polyhydroxyalkanoates (PHA) and polyphosphate (polyP) inclusions, to determine its efficiency. However, tra...

Fuzzy expert system in the prediction of neonatal resuscitation

In view of the importance of anticipating the occurrence of critical situations in medicine, we propose the use of a fuzzy expert system to predict the need for advanced neonatal resuscitation efforts in the delivery room. This system relates the maternal medical, obstetric and neonatal characteristics to the clinical conditions of the newborn, providing a risk measurement of need of advanced neonatal resuscita...

Comparison of continental Portugal and Azores Islands aerosol during a Sahara d...

Copyright © 2002 Elsevier B.V. All rights reserved. ; Airborne particulate matter plays an important role in the Earth's energy balance. One of the main reasons is that the real size of a significant number of the particles, mainly those of anthropogenic origin, is similar to the wavelength of visible light. Knowledge of the composition of such particles, as well as their dynamics and trajectories in the atmos...

Analysis of Atmospheric Aerosols Using the Lisbon Nuclear Micropore

Proceedings of the XXXVI Zakopane School of Physics, Zakopane 2001. ; Copyright © 2001 Polish Academy of Sciences. ; The nuclear microprobe installed at Instituto Tecnológico e Nuclear, in Lisbon, was used in the analysis of aerosols collected at the Azores islands. Samples from two different aerosol groups were analysed. One referred to aerosols that were carried from North America and the other one containe...

Correlação anátomo-clínica: granulomatose sistêmica por talco em drogadicto hiv...

É descrita a correlação anatomopatológica de um paciente usuário de drogas injetáveis com talcose sistêmica acometendo pulmões, pleuras, fígado, baço e linfonodos e que desenvolveu hipertensão arterial pulmonar e cor pulmonale. Destaca-se o fato de que apesar do uso crônico de drogas injetáveis e outros comportamentos de alto risco para infecção pelo retrovírus, o paciente era HIV negativo, não apresentava linf...

The effect of selenium supplementation on polyunsaturated fatty acids in rat

The purpose of this work was to study plasma, adipose tissue, and liver fatty acids percentages of Wistar rats that drank water supplemented with several levels of sodium selenite for 1, 3, and 6 mo. In a general way, percentages of saturated, monounsaturated, and polyunsaturated fatty acids of supplemented groups were not different from those obtained with nontreated animals in the analyzed tissues. However, i...

Nocardia infection in renal transplant recipient: diagnostic and therapeutic co...

In the present report the authors discuss the diagnostic difficulties, therapeutic measures and the clinical course of Nocardia infection which occurred among renal transplant recipients at the University Hospital of the Faculty of Medicine of Ribeirão Preto, University of São Paulo (UH-FRP), from 1968 to 1991. Among 500 individuals submitted to renal transplant, 9 patients developed Nocardiosis at varying time...
