INTRODUCTION First antiretroviral therapy (ART) is often switched to simpler, more potent or better tolerated regimens (1, 2). Although discontinuation rates are frequently studied, the durability of regimens is rarely approached. MATERIALS AND METHODS Retrospective study with the following objectives: analyze first ART schemes and their durability in(More)
Wheat straw was subjected to three different processes prior to saccharification, namely alkaline pulping, natural pulping and autohydrolysis, in order to study their effect on the rate of enzymatic hydrolysis. Parameters like medium concentration, temperature and time have been varied in order to optimize each method. Milling the raw material to a length(More)
An integrated strategy was followed to valorise rice straw, one of the most relevant biomass feedstocks available worldwide, to selectively recover solubilised hemicelluloses and lignin. The pathway encompassed the use of autohydrolysis to hydrolyse the hemicelluloses and an ethanol-based organosolv process to solubilise lignin. Several autohydrolysis(More)
OBJECTIVES To assess prevalence, predictive factors, and prognostic impact on in-hospital mortality of anemia, iron deficiency anemia (IDA), iron deficiency with or without anemia (ID), and iron deficiency without anemia (IDWA) in patients admitted to an internal medicine ward. METHODS This 1-year prospective study collected data on demographics, medical(More)
Matos LV, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-219873 Description Liver abscess (LA) refers to a suppurated cavity caused by the invasion of liver parenchyma, most commonly by Gram-negative bacteria. Although rare, it is potentially life-threatening. Giant LA (>10 cm) is even more uncommon. Symptoms and signs are non-specific and the diagnosis(More)
This work evaluates the bifidogenic potential of substituted xylo-oligosaccharides (XOS) obtained from a lignocellulosic feedstock (corn straw). Autohydrolysis was used to selectively hydrolyse the xylan-rich hemicellulosic fraction and the soluble oligosaccharides were purified by gel filtration chromatography. Selected oligosaccharides fractions within(More)
Pheochromocytomas are rare tumours originating in chromaffin cells, representing 0.1-1% of all secondary hypertension (HT) cases. The majority are benign and unilateral, characterised by the production of catecholamines and other neuropeptides. Mainly located in the adrenal gland, they are more frequent between the 3rd and 5th decades of life; however,(More)
The hydrolysis of hemicellulosic oligosaccharides (OS) was investigated using acid-activated clays (prepared from natural Porto Santo montmorillonite clay) as catalysts. Acid activation was performed in HCl solution or with aluminium exchange. The clay catalysts were characterized by XRD, N2 adsorption isotherms, CEC, FTIR, titration of acid sites in water(More)
