Water Quality Assessment of a Hydro-Agricultural Reservoir in a Mediterranean R...

In regions where drought has become a common occurrence for most of the year and where agriculture is the main economic activity, the development of hydro-agricultural systems has made it possible to improve water management. Despite this, the intensification of agriculture combined with climate change leads to a potential decrease in water quality and water management practices are essential to improve agro-en...

Chronic obstructive pulmonary disease exacerbations' management in Portuguese h...

Introduction and Objectives: In order to improve the quality of chronic obstructive pulmonary disease (COPD) patients' care, better knowledge of clinical practice and the factors associated with patient outcomes are needed. This study aimed to evaluate the relation between clinical practice and the outcomes of patients admitted for COPD exacerbations in Portuguese hospitals. Materials and Methods: Observational...

The usefulness of ecotoxicological tools to improve the assessment of water bod...

This study aimed to analyse the added value of using ecotoxicological tools to complement and improve the assessment of natural water bodies status, in situations of climate change, with a higher frequency of extreme events as floods or droughts. Four water bodies of streams in the Guadiana Basin (Álamos, Amieira, Lucefécit, Zebro) were studied in 2017 and 2018 and classified based on the Water Framework Direct...

Occurrence and risk assessment of pesticides in a Mediterranean Basin with stro...

The study aimed to assess the occurrence and the environmental risk of a group of 51 selected pesticides in the Guadiana Basin (a biodiversity hotspot, in the Mediterranean). The most abundant pesticides were bentazone and 2,4-D, while terbuthylazine together with terbutryn constituted the most ubiquitous pesticides. Eighteen out of the 38 pesticides detected are no longer approved in Europe, and 5 of them are ...

Gastroenteropancreatic Neuroendocrine Neoplasia Characterization in Portugal: R...

Background: The incidence of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) has been increasing in the last five decades, but there is no large-scale data regarding these tumours in Portugal. We conducted a cross-sectional, multicentric study in main Portuguese centers to evaluate the clinical, pathological, and therapeutic profile of GEP-NENs. Methods: From November, 2012, to July, 2014, data from ...

Helicobacter pylori prevalence, histological and antibiotic resistance patterns...

Background : Decreasing prevalence of H. pylori infection has been reported worldwide, in parallel with the improvement in sociodemographic conditions. In contrast, in Portugal, there is still a high prevalence of infection, including in pediatric population, and of gastric carcinoma. Aim : This study aims to evaluate H. pylori prevalence, histological and antibiotic resistance patterns in symptomatic Portugues...

Removal efficiency of pharmaceutical metabolite caffeine by Vetiveria zizanioid...

Reliability of manual segmentation of cornea, contact lens and tear film using ...

In this study, we aimed to evaluate the intra/inter-session and intra/inter-observer variability of manual segmentation of thickness of the pre-lens tear film, contact lens (CL), post-lens tear film, epithelium, bowman’s layer, stroma and the whole cornea and CLs with a flat and a steep fit, using a commercial high-resolution spectral domain optical coherence tomographer (OCT). Two different observers obtained ...

Occupational exposure to fungi and particles in poultry and bovine slaughterhouses

Dust released due to slaughterhouses activities is largely organic and can be contaminated with bacteria, fungi and endotoxin which may represent a health hazard upon inhalation. In addition several respiratory symptoms have been reported among the exposed workers. Taking this information in consideration a study was performed intending to assess the fungal contamination and particles exposure in poultry and bo...

Influence of technological operations in the dissolved oxygen content of wines

Oxygen plays a crucial role in oenology. The oxygen leads to changes in the chemical and sensory profile of wines. On one hand, the impact of moderate oxygen exposure of red wine has a positive effect in its colour, aromatic bouquet and mouth-feel properties. On the other hand, oxygen has a negative effect on white wine’s quality, as well as the sensory and compositional levels. The purpose of this study was to...
