Nitrate removal from water has been accomplished by heterotrophic biofilms using organic carbon as a source of reducing power. To overcome the natural limitation in organic carbon in water, a poly-epsilon-caprolactone based biofilm carrier that serves simultaneously as a biofilm carrier and as a source of organic carbon was developed and tested in the present work. The feasibility of the new biofilm carrier for...
In the elderly there is a high risk of inappropriate medication and adverse effects of polypharmacy. A 68 year-old female patient resorted to the Emergency Room for suspected stroke. According to the husband, in the six months prior to admission, she became progressively disorientated and dependent. She had resorted to various appointments from different specialties and was polymedicated. It was impossible to c...
Os autores descrevem um caso clínico dum lactente com um síndrome polimalformativo que foi internado com um mês e meio de idade na enfermaria de Pediatria do Hospital Geral de Santo António por um síndrome de dificuldade respiratória. Ao exame clínico apresentava um síndrome polimalformativo com: assimetria da comissura labial com o choro, inserção baixa dos pavilhões auriculares e hemivértebras dorsais detecta...
Direct electrochemical reduction of CO2 is a process that could contribute to the reduction of the emission of greenhouse gases by using CO2 as a raw material for fuel production. This paper focuses on voltammetric studies of functionalized electrodes for the electrochemical conversion of CO2 and reports on its use as a tool for electrode screening and optimization. Nickel substrates modified with copper and ru...
he mission of Omnidea, a Portuguese SME is to perform leading edge R&D in innovative energy concepts. In collaboration with Research Institutes Omnidea is developing a technology based upon a regenerative energy storage cycle. In this cycle the recharge system converts CO2 into hydrocarbons using a renewable source of power. The discharge system produces electrical energy when hydrocarbons and oxygen from the r...
Objectives: The aim of this study is to identify and quantify apoptosis in renal tissue, using a biochemical marker (TUNEL) in a pig haemorrhagic model, after intravascular volume replacement with Ringer's lactate RL) or Hydroxyethylstarch (HES) 130/0.4) solutions. Methods: 18 Large White pigs underwent total intravenous anaesthesia (TIVA) with propofol and remifentanil. 25 ml/kg of arterial blood were removed ...
TUNEL staining is one of the most frequently used method to detect apoptosis in renal tissues. The aim of this part of the study was to evaluate kidney damage after acute bleeding and volume replacement, with a colloid or a crystalloid, in a pig model
