Dynamic assessment of self-regulated learning in preschool.

The assessment of self-regulated learning is a relevant research topic in early childhood development. However, there are few ecologic measures to assess self-regulated learning in preschool as a dynamic and multidimensional process. This study aims to fill this gap by presenting the development and validation of the Dynamic Assessment of Self-regulated learning in Preschool (DASP) method.

Serious Game-based Psychosocial Intervention to Foster Prosociality in Cyberbullying Bystanders.

Bystanders of cyberbullying play an important role in the resolution of such situations and therefore, it is beneficial to promote self-regulation strategies that enable them to engage in prosocial behavior in these contexts. We propose that serious game-based psychosocial interventions with profile-based social agents can encourage prosocial bystander behavior in cyberbullying. A pilot quasi-experimental study with repeated and pre/post measurements was performed.

Portuguese higher education students' adaptation to online teaching and learning in times of the COVID-19 pandemic: personal and contextual factors.

The COVID-19 pandemic brought about a global crisis affecting all sectors of society. Higher education is no exception. The closure of higher education institutions has dictated a sudden and unexpected transition from face-to-face to remote teaching to mitigate the spread of the SARS-CoV-2.

Workplace Bullying and Presenteeism: The Path Through Emotional Exhaustion and Psychological Wellbeing.

Objective: Workplace bullying is an increasing phenomenon that concerns managers and employees. However, few studies have investigated how workplace bullying relates with work-related exhaustion and indicators of productivity loss due to presenteeism. Thus, the aim of the present study was to examine the intervening variables of emotional exhaustion and psychological wellbeing in the direct and indirect relationships between workplace bullying and indicators of productivity loss due to presenteeism.

Assessment of the non-protein amino acid BMAA in Mediterranean mussel Mytilus galloprovincialis after feeding with estuarine cyanobacteria.

To determine whether 2-amino-3-methylaminopropanoic acid (BMAA) could be taken up by marine organisms from seawater or their diet mussels Mytilus galloprovincialis, collected from the North Atlantic Portuguese shore, were exposed to seawater doped with BMAA standard (for up to 48 h) or fed with cyanobacteria (for up to 15 days). Mussels were able to uptake BMAA when exposed to seawater. Mussels fed with cyanobacteria Synechocystis salina showed a rise in BMAA concentration during feeding and a decline in concentration during the subsequent depuration period.

Prevalence of dental caries and fissure sealants in a Portuguese sample of adolescents.

Introduction: The aims of this study were to assess the prevalence of dental caries and the DMFT index, as well as the distribution pattern of pit and fissure sealants on permanent teeth in a Portuguese sample of adolescents, and to assess whether the existing usage of sealants and socio-demographic factors are correlated to caries prevalence on the examined sample.

Materials And Methods: A cross-sectional study was designed with a sample of 447 adolescents aged 12 to 18 years old, attending a public school in Sátão, Portugal. A self-administered questionnaire with questions about oral health behaviours and socio-economic status was answered by adolescents in the classroom.

Oral health behaviors in a sample of portuguese adolescents: an educational issue.

Background: The objective of this study was to determine the prevalence of oral health behaviors among a sample of Portuguese adolescents and to evaluate the association with socio-demographic factors.

Methods: This cross-sectional study was conducted among 447 adolescents aged 12-19 years, attending a public school in Sátão, Portugal. A self-administered questionnaire was applied for data collection.

Resective surgery in the treatment of super-refractory partial status epilepticus secondary to NMDAR antibody encephalitis.

Background: Anti-NMDAR encephalitis is an increasingly described clinical entity in children, comprising 40% of all cases. We present a case of super-refractory status epilepticus secondary to anti-NMDAR encephalitis treated with emergent resective surgery.

Case Study: A 7 years-old boy presented with progressive abnormal irritability.

Determination of polycyclic aromatic hydrocarbons in coastal sediments from the Porto region (Portugal) by microwave-assisted extraction, followed by SPME and GC-MS.

A simple low-cost, analytical method based on microwave-assisted extraction of sediments, followed by solid phase micro-extraction and gas chromatography mass spectrometry, was developed and validated for the quantification of sixteen polycyclic aromatic hydrocarbons (PAHs) in marine and estuarine sediment samples. The PAHs were those included in the United States Environmental Protection Agency (US EPA) priority list. Method detection limits were between 0.

Drug delivery systems: Advanced technologies potentially applicable in personalized treatments.

Advanced drug delivery systems (DDS) present indubitable benefits for drug administration. Over the past three decades, new approaches have been suggested for the development of novel carriers for drug delivery. In this review, we describe general concepts and emerging research in this field based on multidisciplinary approaches aimed at creating personalized treatment for a broad range of highly prevalent diseases (e.
