Ventilação Mecânica numa Unidade de Cuidados Intensivos Pediátricos

Os autores fazem a análise dos doentes submetidos a ventilação mecânica na Unidade de Cuidados Intensivos Pediátricos do Hospital de Dona Estefânia, num período de 33 meses, desde a sua abertura em Abril de 1991 até ao final de Dezembro de 1993.Neste período foram internadas na Unidade 1513 crianças, das quais 264 (17.4%) foram ventiladas.A idade dos doentes ventilados variou entre os 28 dias e os 15 anos (médi...

Disposition of [U-2H7]glucose into hepatic glycogen in rat and in seabass

The stimulation of hepatic glycogenesis is a ubiquitous response to a glucose challenge and quantifying its contribution to glucose uptake informs its role in restoring euglycemia. Glycogenesis can be quantified with labeled water provided that exchange of glucose-6-phosphate hydrogen 2 (G6P-H2) and body water via glucose-6-phosphate isomerase, and exchange of positions 4, 5 and 6 hydrogens (G6P-H456) via trans...

Bilateral proliferative retinopathy as the initial presentation of chronic myel...

The authors report a rare case of a 48-year-old male with chronic myeloid leukemia (CML) who initially presented with a bilateral proliferative retinopathy. The patient complained of recent visual loss and floaters in both eyes (BE). Ophthalmologic evaluation revealed a best corrected visual acuity (BCVA) of 20/50 in the right eye and 20/200 in the left eye (LE). Fundoscopy showed the presence of bilateral peri...

Mould and yeast identification in archival settings: preliminary results on the...

This project was developed to fully assess the indoor air quality in archives and libraries from a fungal flora point of view. It uses classical methodologies such as traditional culture media – for the viable fungi – and modern molecular biology protocols, especially relevant to assess the non-viable fraction of the biological contaminants. Denaturing high-performance liquid chromatography (DHPLC) has emerged ...

Estudo in vitro da atividade do extrato etanólico de sementes de bacupari (Rhee...

Streptococcus mutans, principal microrganismo da cavidade oral, desempenha papel preponderante na formação de placas dentárias, sendo considerado o agente etiológico primário da cárie. Rheedia gardneriana, conhecida popularmente como bacupari, é uma planta utilizada com fins medicinais para o tratamento de diversas patologias, e por apresentar atividade antimicrobiana de compostos das folhas contra bactérias Gr...

Abordagem Mini Invasiva da Necrose Pancreática Infectada

Laboratory-induced endolithic growth in calcarenites : biodeteriorating potenti...

This study is aimed to assess the formation of photosynthetic biofilms on and within different natural stone materials, and to analyse their biogeophysical and biogeochemical deterioration potential. This was performed by means of artificial colonisation under laboratory conditions during 3 months. Monitoring of microbial development was performed by image analysis and biofilm biomass estimation by chlorophyll ...
