Magnetic Resonance Imaging in Multiple Sclerosis: An Analysis of the Implementa...
Cordeiro, Alyne; Marques, Ana João; Castro, Ana Rita; Silva, Cristiana; Carapinha, Duarte; Ferreira, Francisca; Schön, Miguel; Jardim Pereira, DanielaIntroduction: Magnetic resonance imaging (MRI) plays a critical role in diagnosing and monitoring people with multiple sclerosis (MS). The 2020 Portuguese Consensus on Magnetic Resonance Imaging in Multiple Sclerosis aimed to standardize MRI use. This study evaluated the implementation of the consensus in clinical practice.Methods: This is an observational, retrospective, longitudinal and multicentric study com...
Combination of SPE and pH adjustment for the simultaneous spectrophotometric de...
Ferreira, Francisca; Ribas, Tânia; Mesquita, Raquel; Rangel, AntónioCopper, zinc, and manganese are commonly found in both natural and treated water sources. Although these metals are essential micronutrients, their accumulation, even at low concentrations, can lead to serious health issues. Therefore, continuous and accurate monitoring of these elements in environmental and drinking water is crucial to ensure public safety. Solid Phase Extraction (SPE) is a widely used sample ...
Antibody blockade of the PSGL-1 immune checkpoint enhances T-cell responses to ...
Pereira, João L.; Arede, Liliana; Ferreira, Francisca; Matos, Andreia; Pereira, Dulcineia; Santos, Rita F.; Carmo, Alexandre M.; Oliveira, Maria J.Despite advancements in cancer immunotherapy, most lymphomas remain unresponsive to checkpoint inhibitors. P-selectin glycoprotein ligand-1 (PSGL-1), recently identified as a promoter of T-cell exhaustion in murine melanoma models, has emerged as a novel immune checkpoint protein and promising immunotherapeutic target. In this study, we investigated the potential of PSGL1 antibody targeting in B-cell lymphoma. ...
Evaluating the impact of high sugar diet on juvenile rats: a histomorphological...
Ferreira, Francisca; Leal, Sandra; Garcez, Fernanda; Nogueira, SofiaBackground: Intestinal barrier is an important structure that defends and maintains the homeostasis of the host. [1-3]. It is highly influenced by food due to the interaction between nutrients and gut microbiota [2]. A diet rich in sugar can disrupt gut homeostasis, leading to a dysfunctional barrier and causing chronic diseases [3]. The enterochromaffin cells (ECs) are dispersed throughout the intestine wall, ...
From piggery wastewater to wheat using microalgae towards zero waste
Ferreira, Alice; Figueiredo, Daniel; Ferreira, Francisca; Marujo, Ana; Bastos, Carolina R. V.; Martin-Atanes, Guillermo; Ribeiro, BelinaABSTRACT: Microalgae production is still expensive, driving the need to lower costs while strengthening the industry's environmental sustainability. Microalgae are recognized tools for efficient wastewater treatment, offering the recycling of nutrients and water for agriculture, and producing biomass rich in growth-promoting compounds to improve plant productivity and resistance to adverse conditions. The use o...
The Effect of a Healthy Lifestyle on Preventing and Improving Symptoms in Patie...
Silva, Carlos; Ferreira, Francisca; Santos Coelho, Francisco; Sá, Maria José; Guimarães, JoanaIntroduction: Multiple sclerosis (MS) patients expect healthcare professionals to provide them with information on healthy lifestyles. Thus, the purpose of this systematic review is to evaluate and compile measures with scientific evidence related to these lifestyles and to address solutions to the main barriers to their implementation. Methods: Research of articles in the international databases PubMed® and Sc...

Flexural performance of squared one-sided CFRP patches: modelling and experimen...
Abdelfattah, Ibrahim; Ferreira, Francisca; Nasr Saleh, Mohamed; Reis, Paulo N. B.; Freitas, Sofia Teixeira deThree-point bending analysis, experimental and numerical, is conducted for three different sizes, 30*30 mm, 40*40 mm and 60*60 mm, of one-sided square cross-ply TEXIPREG HS 160 RM carbon-fiber-reinforced polymer (CFRP) patches as well as intact and notched specimens. The tests are carried out with the aim to study the influence of the patch’s size on the flexural properties of the specimen. Hashin-2D damage ini...
Exploring different pretreatment methodologies for allowing microalgae growth i...
Ferreira, Alice; Figueiredo, Daniel; Cardeiras, Rodrigo; Nabais, Rui; Ferreira, Francisca; Ribeiro, Belina; Cordovil, Cláudia; Acien, GabrielABSTRACT: The overapplication of manure on agricultural soils leads to nitrogen and phosphorus discharge into the aquatic environment, resulting in serious eutrophication problems and decreased water quality. Piggery wastewater (PWW) can be treated by microalgae to recycle nutrients, but the toxic levels of ammonia and organic matter hinder their growth. Fresh water is usually used to dilute PWW, but it is a sc...
