Segmental cardiac strain assessment by two‐dimensional speckle‐tracking echocardiography in surviving MIS‐c patients: Correlations with myocardial flow reserve (MFR) by 13 N‐ammonia PET‐CT

Gabriela Nunes Leal, Camila Astley, Marcos Santos Lima, Maria de Fátima Rodrigues Diniz, more

Background Multisystem inflammatory syndrome in children (MIS‐c) is associated with severe cardiovascular impairment and eventually death. Pathophysiological mechanisms involved in myocardial injury were scarcely investigated, and cardiovascular outcomes are uncertain. Autopsy studies suggested that microvascular dysfunction may be relevant to LV impairment. Objective We aimed to evaluate segmental...

00003 Biotech > 2018 > 8 > 7 > 1-9

In this study, we evaluated the potential of yeasts isolated from Amazon to produce second-generation ethanol from sugarcane bagasse delignified with alkaline hydrogen peroxide and hydrolysed with commercial enzyme preparation. The best efficiency savings in glucose and release of xylose were determined by considering the solids and enzyme loads. Furthermore, we selected Spathaspora passalidarum UFMG-CM-Y473...

Açai (Euterpe oleracea Mart.) dietary intake affects plasma lipids, apolipoproteins, cholesteryl ester transfer to high-density lipoprotein and redox metabolism: A prospective study in women

Daniela Pala, Priscila Oliveira Barbosa, Carla Teixeira Silva, Melina Oliveira de Souza, more

Clinical Nutrition > 2018 > 37 > 2 > 618-623

The açai fruit (Euterpe oleracea Martius), which is native to the Brazilian Amazon region, was shown to have high polyphenols and MUFA contents. In this study, we aimed to assess the effects of açai consumption on plasma lipids, apolipoproteins, the transfer of lipids to HDL (which is a relevant HDL function), and some biomarkers of redox metabolism. Forty healthy volunteer women aged 24 ± 3 years...

Load forecasting through functional clustering and ensemble learning

Fátima Rodrigues, Artur Trindade

Knowledge and Information Systems > 2018 > 57 > 1 > 229-244

In this paper a load forecasting methodology for 2 days-ahead based on functional clustering and on ensemble learning is presented. Due to the longitudinal nature of the load diagrams, these are segmented using a functional clustering procedure to group together similar daily load curves concerning its phase and amplitude. Next, ensemble learning of extreme learning machine models, developed for several...

A note on symmetry classes of tensors and Specht modules

J.A. Dias da Silva, Fátima Rodrigues, Pedro C. Silva, Maria M. Torres

Linear Algebra and its Applications > 2017 > 531 > C > 118-128

We construct induced bases for critical orbital spaces indexed by standard tableaux. As a corollary we obtain an explicit isomorphism of C[Sm]-modules between Specht modules and critical orbital spaces which yields a realization of the complete set of complex irreducible representations of the symmetric group in terms of decomposable symmetrized tensors.

Recycling the liquid fraction of alkaline hydrogen peroxide in the pretreatment of corn stover

Bárbara Ribeiro Alves Alencar, Alexandre Libanio Silva Reis, Raquel de Fatima Rodrigues de Souza, Marcos Antônio Morais, more

Bioresource Technology > 2017 > 241 > C > 928-935

The aim of this study was to evaluate the influence of recycling the liquid fraction of pretreatment with alkaline hydrogen peroxide (AHP) on the hydrolysis of corn stover. Corn stover was pretreated in the traditional condition with 7.5% v/v H₂O₂. After pretreatment, the solids were separated from the liquid fraction and five successive reuse cycles of the liquid fraction were tested. The solid fraction...

Alkaline hydrogen peroxide pretreatment of lignocellulosic biomass: status and perspectives

Emmanuel Damilano Dutra, Fernando Almeida Santos, Bárbara Ribeiro Alves Alencar, Alexandre Libanio Silva Reis, more

Biomass Conversion and Biorefinery > 2018 > 8 > 1 > 225-234

Lignocellulosic biomass is a renewable and abundant resource that is suitable for the production of bio-based materials such as biofuels and chemical products. However, owing to its complex chemical composition, it requires a process that enhances the release of sugars. Pretreatment is an essential stage in increasing the efficiency of enzymatic hydrolysis of lignocellulosic biomass. The most widely...

Lipid transfers to HDL are diminished in long-term bedridden patients: association with low HDL-cholesterol and increased inflammatory markers

Wilson Pascoalino Camargo Oliveira, Thauany Martins Tavoni, Fatima Rodrigues Freitas, Bruna Miranda Oliveira Silva, more

Lipids > 2017 > 52 > 8 > 703-709

Plasma lipids have been extensively studied in sedentary and in subjects practicing exercise training, but not in extreme inactivity as occurs in bedridden patients. This is important for the care of bedridden patients and understanding the overall plasma lipid regulation. Here, we investigated plasma lipids, lipid transfers to HDL and inflammatory markers in bedridden patients. Fasting blood samples...

Extending the Dimensional Templates Approach to Integrate Complex Multidimensional Design Concepts

Rui Oliveira, Fátima Rodrigues, Paulo Martins, João Paulo Moura

Lecture Notes in Computer Science > Data Warehousing and Knowledge Discovery > Physical and Conceptual Data Warehouse Models > 26-38

In the past, several approaches have been devised to semi- automate the multidimensional design (MDD) of Data Warehouse (DW) projects. Such approaches highly contribute to more expertise- independent and deterministic MDD results. Among them, only the Dimensional Templates Approach (DTA) focuses on solving the critical resource containment problems of DW prototypes. Originally, the DTA allows...

Dimensional Templates in Data Warehouses: Automating the Multidimensional Design of Data Warehouse Prototypes

Rui Oliveira, Fátima Rodrigues, Paulo Martins, João Paulo Moura

Lecture Notes in Business Information Processing > Enterprise Information Systems > Databases and Information Systems Integration > 184-195

Prototypes are valuable tools in Data Warehouse (DW) projects. DW prototypes can help end-users to get an accurate preview of a future DW system, along with its advantages and constraints. However, DW prototypes have considerably smaller development time windows when compared to complete DW projects. This puts additional pressure on the achievement of the expected prototypes’ high quality standards,...
