On the optimization of carob seed peel extraction using aqueous-based acidic sy...
Medronho, Bruno; boutoub, Oumaima; Duarte, Hugo; Aliaño González, María José; Guerra, Rui; Brazio, António; Gonçalves, Sandra; Romano, AnabelaCarob fruit utilization remains limited, with most of their commercial value derived from locust bean gum, which is obtained from seed endosperm. Efficient extraction requires dehusking, which is traditionally performed under harsh conditions. This study aims to develop and optimize a milder, more sustainable dehusking method while preserving seed quality for industrial applications. Various aqueous-based solve...
From lignocellulosic residues to protein sources: insights into biomass pre-tre...
Vera dos Anjos, Isabela; Coelho, Natacha; Duarte, Hugo; Proença, Diogo Neves; Duarte, Maria F.; Jorge de Barros, Raúl José; Raposo, SaraWith the global population steadily rising, the demand for sustainable protein sources has become increasingly urgent. Traditional animal- and plant-based proteins face challenges related to scalability, resource efficiency, and environmental impact. In this context, single-cell protein has emerged as a promising alternative. Derived from microorganisms such as algae, bacteria, fungi, and yeast, single-cell pro...
Exploring professional practice environments and organisational context factors...
Furtado, Luís; Coelho, Fábio; Mendonça, Natália; Soares, Hélia; Gomes, Luís; Sousa, Joana Pereira; Duarte, Hugo; Costeira, Cristina; Santos, CátiaThis scoping review, conducted within the Joanna Briggs Institute (JBI) framework, analysed the recent literature (January 2018 to March 2023) addressing factors inherent to professional practice environments and organisational contexts influencing nurses’ adoption of evidence-based practice (EBP). This review included studies involving nurses regardless of sector, practice setting, and scope of practice. A sys...
Nursing care for acute stroke patients
Conde, Catarina; Duarte, Hugo; Conde, Catarina; Duarte, HugoIntroduction: Stroke is responsible for high levels of mortality. Implementing clinical procedures, such as work instructions, allows the application of interventions based on the latest scientific evidence and guidelines. In the emergency department, nurses play a fundamental role in approaching and caring for patients with suspected stroke in the acute phase. Objective: To determine the usefulness and feasibi...
The influence of pericardial fat on left ventricular diastolic function
Coelho, Patrícia; Duarte, Hugo; Alcafache, Carlos; Rodrigues, FranciscoAbstract: Background: Heart failure is a major cause of morbidity and mortality worldwide; left ventricular diastolic dysfunction plays a leading role in this clinical context. Diastolic dysfunction may be predisposed by increased abdominal fat and, consequently, increased pericardial and epicardial adiposity. This study aimed to determine whether pericardial fat (PF) and epicardial fat (EF) are associated with...
Poly(butylene succinate)-based composites with technical and extracted lignins ...
Melro, Elodie; Duarte, Hugo; Eivazi, Alireza; Costa, Carolina; Faleiro, Maria Leonor; Rosa Da Costa, Ana; Antunes, Filipe E.; Valente, Artur J. M.Poly(butylene succinate) (PBS) has been drawing attention as a reliable biodegradable and sustainable alternative to synthetic petroleum-based polymers. In this study, PBS-lignin composites were developed using a recently extracted lignin (LA-lignin) from pine wood residues employing an innovative sustainable approach. These composites were systematically compared with PBS-based composites formed with commonly ...
Advancements in detection and mitigation strategies for Petroleum-Derived conta...
Duarte, Hugo; Aliaño González, María José; Medronho, BrunoThe exponential increase in the production and transportation of petroleum-derived products observed in recent years has been driven by the escalating demand for energy, textiles, plastic-based materials, and other goods derived from petroleum. Consequently, there has been a corresponding rise in spills of these petroleum derivatives, particularly in water sources utilized for transportation or, occasionally, i...
On the valorization of olive oil pomace: a sustainable approach for methylene b...
Saoudi Hassani, El Mokhtar; Duarte, Hugo; Brás, João; Taleb, Abdeslam; Taleb, Mustapha; Rais, Zakia; Eivazi, Alireza; Norgren, Magnus; Romano, AnabelaCurrently, industrial water pollution represents a significant global challenge, with the potential to adversely impact human health and the integrity of ecosystems. The continuous increase in global consumption has resulted in an exponential rise in the use of dyes, which have become one of the major water pollutants, causing significant environmental impacts. In order to address these concerns, a number of wa...
Lignin-furanic rigid foams: Enhanced methylene blue removal capacity, recyclabi...
Duarte, Hugo; Brás, João; Saoudi Hassani, El Mokhtar; Aliaño González, María José; Magalhães, Solange; Alves, Luís; Valente, Artur J. M.Worldwide, populations face issues related to water and energy consumption. Water scarcity has intensified globally, particularly in arid and semiarid regions. Projections indicate that by 2030, global water demand will rise by 50%, leading to critical shortages, further intensified by the impacts of climate change. Moreover, wastewater treatment needs further development, given the presence of persistent organ...
Sustainable extraction of polyphenols from vine shoots using deep eutectic solv...
Duarte, Hugo; Aliaño-González, María José; Cantos-Villar, Emma; Faleiro, Leonor; Romano, Anabela; Medronho, BrunoVine shoots are the main by-products of grapevine pruning with no added value. In the present study, deep eutectic solvents (DESs) were used as alternatives to traditional chemical solvents, for the extraction of phyto chemicals from grapevine shoots. Three levulinic acid-based DESs were tested for the first time, and their per formance was compared to methanol (a standard chemical solvent) regarding the extrac...
