Sustainability assessment of collagen extraction from fish skins: A comparative...

ABSTRACT: Collagen from blue shark skins offers a promising solution to utilize fishery by-products, reducing waste and improving resource efficiency. This study develops green chemistry-based extraction processes to minimize reliance on traditional chemical methods and lower environmental impacts, prioritizing sustainability and circularity. Two methods for collagen extraction are compared: a conventional alka...

School and family ecosystem: Incentives and barriers to school–family communica...

The aim of the study was to explore the factors and barriers related to the incentive and opportunity of school–family communication. This work is part of the HOUSE-Colégio F3 Project, ULisbon, which included 1,143 first-year university students from the University of Lisbon, with average age of 19.61 ± 3.96 years. The young people who had better communication with their parents, greater family support and bett...

COVID-19 and lockdown, as lived and felt by university students

In the last 2 years, the COVID-19 pandemic has spread all over the world, forcing the closure of universities, among other unusual measures in recent history. (1) Background: This work is based on the study HOUSE-ULisbon, a survey carried out during the second confinement (March-May 2021) in Portugal with the collaboration of all the Faculties of the University of Lisbon (UL). The present work aims to explore g...

Chronic conditions and school participation of first-year university students: ...

Students with chronic conditions (CC) tend to experience several barriers in terms of their school participation and performance. Therefore, the present study aims to explore the factors related to the time of diagnosis of CC (recent/non-recent), the barriers to participation and academic success (health condition, people's attitude towards CC and school physical environment), the physical and mental health (ph...

Combined hydrothermal pre-treatment and enzymatic hydrolysis of corn fibre: pro...

ABSTRACT: Ferulic acid may be used as a nutraceutical ingredient or as a substrate to produce bio-vanillin. There is an increasing market demand for ferulic acid obtained from natural sources such as low-cost agro-industrial by-products, due to its potential applications as nutraceutical ingredient and as a substrate to produce biovanillin. This work aims to study ferulic acid recovery from corn fibre (one of t...

Evaluation of the fusion inhibitor P3 peptide as a potential microbicide to pre...

Microbicides are an important strategy for preventing the sexual transmission of HIV but, so far, the most advanced tenofovir-based microbicides have had modest efficacy. This has been related to adherence problems and high prevalence of tenofovir-resistant HIV-1 strains. P3 is a new peptide with potent activity against HIV that may be a good microbicide candidate. In this work P3 was formulated in a gel of hyd...

Analysis of phenolic compounds in Muscatel wines produced in Portugal

A liquid chromatography method associated with mass spectrometry and diode array, fluorescence and electrochemical detectors was used in order to study phenolic composition of Muscatel sweet wines from Setubal region in Portugal. Samples were collected during winemaking production at different representative producers of this region. Total phenolic contents of samples were also determined using the Folin-Ciocal...

Identification of flavonol glycosides in winemaking by-products by HPLC with di...
