Isolation of Surfactant-Resistant Pseudomonads from the Estuarine Surface Micro...

Bioremediation efforts often rely on the application of surfactants to enhance hydrocarbon bioavailability. However, synthetic surfactants can sometimes be toxic to degrading microorganisms, thus reducing the clearance rate of the pollutant. Therefore, surfactant-resistant bacteria can be an important tool for bioremediation efforts of hydrophobic pollutants, circumventing the toxicity of synthetic surfactants ...

Sedation with midazolam in flexible bronchoscopy - a prospective study

INTRODUCTION: Sedatives have been increasingly used to improve patient comfort during flexible bronchoscopy (FOB). Due to its rapid-onset, anxiolytic and amnestic properties, midazolam is one of the most commonly used sedatives. OBJECTIVES: To evaluate the effect of sedation with midazolam, including patient tolerance, complications and its potential use on a daily routine basis. MATERIAL AND METHODS: A multi-c...

Avaliação da segurança sísmica de pontes e reforço com FRP´s

A avaliação da segurança e a conservação das pontes têm vindo a suscitar interesse crescente nos últimos anos. O reforço destas estruturas para a acção sísmica é importante, uma vez que são infra-estruturas fundamentais para a intervenção das equipas de socorro em acções pós-sismo, mas também pelas consequências económicas e sociais associadas a eventuais danos severos ou colapso destas obras. O reforço sísmico...

On-demand hydrogen generation by hydrolysis of sodium borohydride in batch reac...

A study was undertaken in order to investigate the potential of hydrogen generation by hydrolysis of sodium borohydride in batch reactors, operating at moderate pressures, in the presence of a reused nickel-ruthenium based catalyst, to feed on-demand a proton exchange membrane fuel cell. The effect of the buffer pressure is explored and hydrogen generation rates are evaluated by changing catalyst amount, operat...

Spondylodiscitis associated with recurrent Serratia bacteremia due to a transju...

We report a case of spondylodiscitis caused by multiresistant Serratia marcescens in a cirrhotic patient who had several Serratia bacteremias after the placement of a transjugular intrahepatic portosystemic shunt (TIPS) device. We concluded that an endovascular stent that can not be removed makes management of recurrent bacteremia difficult. Furthermore, back pain due to bacteremia is indicative of spondylodisc...

Muscle strength but not functional capacity is associated with plasma interleuk...

The association of plasma interleukin-6 (IL-6) levels, muscle strength and functional capacity was investigated in a cross-sectional study of community-dwelling elderly women from Belo Horizonte, Brazil. Elderly people who present controlled chronic diseases with no negative impact on physical, psychosocial and mental functionality are considered to be community-dwelling. Psychological and social stress due to ...
