Gasification of Cork Wastes in a Fluidized Bed Reactor

Biomass gasification has been identified as an option for energetic valorisation of organic wastes. This work aimed to study the gasification of cork industry wastes using a semi-batch fluidized bed reactor. The experimental tests were performed using air as oxidizing agent and sand particles as bed material. The heating was performed with an electrical resistance of 3 kW. The effect of biomass load (2–5.6 g), ...

Glucose and Lipid Dysmetabolism in a Rat Model of Prediabetes Induced by a High...

Glucotoxicity and lipotoxicity are key features of type 2 diabetes mellitus, but their molecular nature during the early stages of the disease remains to be elucidated. We aimed to characterize glucose and lipid metabolism in insulin-target organs (liver, skeletal muscle, and white adipose tissue) in a rat model treated with a high-sucrose (HSu) diet. Two groups of 16-week-old male Wistar rats underwent a 9-wee...

Inhibition of bladder tumour growth by sirolimus in an experimental carcinogene...

To investigate the anticarcinogenic effects of sirolimus 2 mg/kg/day on a rat model of urinary bladder carcinogenesis induced with N-butyl-N(4-hydroxybutyl)nitrosamine (BBN).

Emergência pediátrica pré-hospitalar: experiência de uma Viatura Médica de Emer...

Introdução: As emergências pediátricas representam 5-10% das activações dos serviços de emergência. A VMER (Viatura Médica de Emergência e Reanimação) ao trabalhar no âmbito do pré-hospitalar desempenha um papel crucial na assistência às crianças gravemente doentes e no transporte primário diferenciado.

Omega-3 fatty acids inhibit tumor growth in a rat model of bladder cancer

Omega-3 (ω-3) fatty acids have been tested on prevention and treatment of several cancer types, but the efficacy on "in vivo" bladder cancer has not been analyzed yet. This study aimed at evaluating the chemopreventive efficacy of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) mixture in an animal model of bladder cancer. Forty-four male Wistar rats were divided into 4 groups during a 20-week protoc...

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...

Preventive but not curative efficacy of celecoxib on bladder carcinogenesis in ...

To evaluate the effect of a cyclooxygenase 2 inhibitor, celecoxib (CEL), on bladder cancer inhibition in a rat model, when used as preventive versus as curative treatment. The study comprised 52 male Wistar rats, divided in 5 groups, during a 20-week protocol: control: vehicle, carcinogen: 0.05% of N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN), CEL: 10  mg/kg/day of the selective COX-2 inhibitor Celebrex, preven...

S. Pyogenes invasive disease in a paediatric hospital: 1996-2009.

S. pyogenes is among the most common bacteria in Pediatrics, and is associated with a wide variety of infections and large range of severity.The aim was to evaluate trends of Group A Streptococcal invasive disease in a paediatric tertiary hospital.Retrospective analyses of the medical records of all children with group A streptococcal invasive disease (positive culture obtained from sterile sites), from January...
