Relating air Pollution and Respiratory Diseases Occurrences

Com o apoio RAADRI. ; In this article we study the impact of air pollution on children's health in Portugal. In particular, we focus our attention on the city of Barreiro. We use the general linear methods (GLM), taking advantage of all the ease of handling and analyzing data in order to relate air quality and health. We relate levels of air pollution and incidence of entries from children with symptoms of res...

On the development of an automatic voice pleasantness classification and intens...

WOS:000311524800005 (Nº de Acesso Web of Science) ; In the last few years, the number of systems and devices that use voice based interaction has grown significantly. For a continued use of these systems, the interface must be reliable and pleasant in order to provide an optimal user experience. However there are currently very few studies that try to evaluate how pleasant is a voice from a perceptual point of...

Oxidative stress responses and histological hepatic alterations in barbel, Barb...

Barbel (Barbus bocagei) a common species in Portuguese rivers was studied to assess the impact of water contamination on hepatic oxidative stress response, lipid peroxidation and histology. The Vizela River is a tributary of the Ave River, located in one of the most industrialized areas of Portugal. The oxidative stress biomarkers analyzed included superoxide dismutase, catalase, glutathione S-transferase, glut...

Coagulant properties of Moringa oleifera protein preparations : application to ...

This work aimed to characterize the coagulant properties of protein preparations from Moringa oleifera seeds to remove humic acids from water. Three distinct preparations were assayed, namely extract (seeds homogenized with 0.15 M NaCl), fraction (extract precipitated with 60 % w/v ammonium sulphate) and cMoL (protein purified with guar gel column chromatography). The extract showed the highest coagulant activi...

Antioxidant activity of Moringa oleifera tissue extracts

Moringa oleifera is an important source of antioxidants, tools in nutritional biochemistry that could be beneficial for human health; the leaves and flowers are used by the population with great nutritional importance. This work investigates the antioxidant activity of M. oleifera ethanolic (E1) and saline (E2) extracts from flowers (a), inflorescence rachis (b), seeds (c), leaf tissue (d), leaf rachis (e) and ...

Protein purification by affinity chromatography

Lactic acid production by new Lactobacillus plantarum LMISM6 grown in molasses:...

A Plackett-Burman experimental design was used to evaluate seven medium components added to molasses (corn steep liquor, sodium acetate, magnesium sulfate, manganese sulfate, ammonium citrate, potassium phosphate and Tween 80). Corn steep liquor (CSL), K2HPO4 and Tween 80 increased lactic acid production. The concentrations of these three components as well as the molasses were further optimized using the respo...

Miocardiopatia de etiologia isquémica versus não-isquémica: haverá diferenças n...

INTRODUCTION: Previous studies have associated heart failure (HF) of ischemic etiology with worse prognosis compared to HF from non-ischemic cardiomyopathy. HF treatment has evolved significantly in recent years. Has this evolution had an impact on this prognostic gap? OBJECTIVE: The aim of our study was to compare patients with advanced HF--nonischemic versus ischemic etiology--in terms of baseline characteri...

Interaction of Moringa oleifera seed lectin with humic acid

The aim of this work was to characterise the affinity of protein preparations from Moringa oleifera seeds, specifically extract (seeds homogenised with 0.15 M NaCl), fraction (extract precipitated with 390 mg mL−1 of ammonium sulphate) and cMoL (coagulant M. oleifera lectin) to bind humic acids using a haemagglutinating activity assay with rabbit erythrocytes and a radial diffusion assay in agarose gel. Specifi...

Coagulant and antibacterial activities of the water-soluble seed lectin from Mo...

Aims: The aim of this work was to analyse the coagulant and antibacterial activities of lectin isolated from Moringa oleifera seeds that are used for water treatment. Methods and Results:  The water-soluble M. oleifera lectin (WSMoL) was separated from nonhemagglutinating components (NHC) by chitin chromatography. WSMoL fluorescence spectrum was not altered in the presence of ions that are often present in hig...
