Associação entre a competência motora e o tempo de reação em crianças do ensino...

Este relatório final de estágio, realizado no âmbito do 2.º ciclo de Estudos em Ensino de Educação Física no Instituto Piaget, em Almada, apresenta uma reflexão sobre as competências adquiridas durante a Prática de Ensino Supervisionada (PES). Estruturado em quatro áreas — Profissional, Social e Ética; Desenvolvimento do Ensino e Aprendizagem; Participação na Escola e Relação com a Comunidade; e Desenvolvimento...

Breaking the virus: yeast glucans as an effective alternative to acyclovir in H...

Glucans, structural polysaccharides in the yeast cell wall, are known for their biological and immunomodulatory capacities, helping in prevention and management of infections. Herpes simplex virus type 1 (HSVI) is a prevalent infection that causes great comorbidity and is challenging to treat due to the adverse effects of standard antiviral drugs like acyclovir. This study assessed the potential of yeast glucan...

Modeling microgravity using clinorotation in a microfluidic environment: a nume...

Microgravity simulation is essential for studying particle dynamics in space-related applications where traditional gravitational effects are absent. This study presents a numerical investigation of particle behavior in a clinostat-driven microfluidic channel, aiming to simulate microgravity conditions. A computational model was developed in COMSOL Multiphysics to analyze the impact of channel size, particle di...

Chemical and Mineralogical Characterization ofWaste from Abandoned Copper and M...

ABSTRACT: This study examines the chemical and mineralogical composition of waste materials from abandoned copper and manganese mines in the Iberian Pyrite Belt, Portugal, as a first step toward their potential recycling for critical and strategic raw materials (CRM and SRM). Using portable X-ray fluorescence (pXRF) and other analytical techniques, this research highlights the presence of valuable elements, inc...

Potential for trophic transfer of microplastics in the smallspotted catshark’s ...

Microplastics (MPs) are increasingly prevalent pollutants in marine environments, raising concerns about their potential to transfer across trophic levels. However, the extent and significance of such transfer remain uncertain. This study aimed to (i) characterise MPs in the digestive tracts (GITs) of three ecologically connected species — the small-spotted catshark (Scyliorhinus canicula), pouting (Trisopterus...

Nurses' Social Representations of Men's Sexual Health Care Access: Preliminary ...

Men’s access to sexual health care is influenced by the nurses’ symbolic universes, translated into maps of signification and normative idealization that structure their practices. Aim: The aim of the study was to analyze nurses’ social representations of men’s sexual health, considering the barriers and possibilities in accessing health care. Methods: Descriptive study with qualitative approach. Data were coll...

Circular economyeast: saccharomyces cerevisiae as a sustainable source of gluca...

Glucans, a polysaccharide naturally present in the yeast cell wall that can be obtained from side streams generated during the fermentation process, have gained increasing attention for their potential as a skin ingredient. Therefore, this study focused on the extraction method to isolate and purify water-insoluble glucans from two different Saccharomyces cerevisiae strains: an engineered strain obtained from s...

Exploring cannabidiol (CBD) and cannabigerol (CBG) safety profile and skincare ...

Cannabinoids have long been known for their bioactive properties, with their topical application as anti-inflammatory compounds being at the forefront of research for the past decade. Concurrently, the cosmetic market is a fast-growing industry in constant need of new biomolecules. In this work, we studied the safety profile for topical applications of two cannabinoids: cannabidiol (CBD) and cannabigerol (CBG) ...

Anti-aging potential of a novel ingredient derived from sugarcane straw extract...

Natural and sustainable anti-aging ingredients have gained attention from the cosmetic industry. This study evaluated the anti-aging potential of a sugarcane straw extract-based (SSE) cosmetic ingredient. First, cytotoxicity tests were assessed in keratinocytes and fibroblast cell lines, and sensitization was carried out through the direct peptide reactivity assay. Subsequently, various anti-aging properties we...
