Abcesso Hepático Amebiano. A Propósito de um Caso Clínico

A amebíase é uma das doenças parasitárias mais comuns no mundo. As principais formas invasivas da doença são a colite amebiana e o abcesso hepático. Apresenta-se o caso clínico de um homem de 42 anos admitido com um quadro agudo de febre elevada e dor abdominal no hipocôndrio direito com dois dias de evolução. A tomografia axial computorizada do abdómen revelou a presença de 3 lesões abcedadas a nível do lobo d...

The role of micro-ribonucleic acids in normal hematopoiesis and leukemic T-lymp...

Micro-ribonucleic acids (microRNAs) are small molecules containing 20-23 nucleotides. Despite their small size, it is likely that almost every cellular process is regulated by them. Moreover, aberrant microRNA expression has been involved in the development of various diseases, including cancer. Although many data are available about the role of microRNAs in various lymphoproliferative disorders, their impact o...

Erythropoietin doping as cause of sudden death in athletes: an experimental study

Aims: To evaluate the cardiovascular (CV) effects of rhEPO treatment in rats under chronic aerobic exercise and to assess the probable cause of sudden death in one rat. Protocol: Male Wistar rats: control - sedentary; rhEPO - 50 IU/Kg/3xwk; swimming (EX) -1 hr, 3x/wk; EX+EPO. Hematology, catecholamines and serotonin, redox status and inflammation, were assessed. One rat of EX+EPO group suffered a sudden death e...

Nematodes vs Macrofauna assemblages along an estuarine gradient (Mondego estua...

The spatial distribution of the nematodes and macrofauna communities in the subtidal sediments along estuarine gradient in the Mondego estuary was studied. The main aim is to compare the response of the nematodes and macrofauna communities structure adjusted for each estuarine stretch. Spatial distribution of nematode assemblages followed the estuarine gradients, allowing to distinguish: The freshwater and olig...

Opportunistic macroalgae metrics for transitional waters. Testing tools to asse...

Macroalgae communities constitute one of the ecological quality elements for the evaluation of the ecological quality status (EQS) of coastal and transitional waters, required to implement the WFD. While these algae are natural components of estuarine systems and play important roles in several estuarine processes, macroalgal blooms are of ecological concern because they can reduce the habitat quality. Several ...

Applying quality status criteria to a temperate estuary before and after the mi...

The Mondego estuary is a well-described polyhaline type of transitional water located at the North Atlantic Ocean Ecoregion, where cultural eutrophication progressed over the last decades of the 20th century. Consequently, and due to huge productivity of Ulva spp. Zostera noltii meadows were severely reduced causing the whole ecosystem to become impoverished in terms of macrofaunal abundance, biomass and specie...

Applicability of ecological evaluation tools in estuarine ecosystems: the case ...

Abstract In accordance with the Water Framework Directive guidelines (WFD, 2000, European Communities Official Journal L327 2000/60/EC), classification schemes and ecological evaluation tools (based on benthic invertebrate fauna data sets from 1990 to 2002) were applied in the lower Mondego estuary. Two distinct scenarios could be tested due to the implementation of mitigation practices in 1999, following a lo...

A simple ESR identification methodology for electrolytic capacitors condition m...

Electrolytic capacitors are usually used in power electronic systems for smoothing, energy storage or filtering. They have the best overall performance for these objectives being a critical element in the design of these systems, in several applications, with different requirements. But, unfortunately, in most cases, they are the most life-limiting device. The expected life of electrolytic capacitors depends on...
