In an academic semester, living in social isolation and under restrictions of the pandemic, we organized weekly multidisciplinary seminars from a postgraduate course program in Curitiba, Southern Brazil, integrating students from different regions of Brazil and South America. Outstanding researchers from Brazil, Germany, France, Argentina, Mexico,…

This study explores the relevance of the breathalyzer test as a harm reduction tool in outreach interventions implemented in nightlife environments. Specifically, it analyzes (i) gender and age differences on Blood Alcohol Concentration (BAC); (ii) the association between BAC levels and expected effects and (iii) the relationship between BAC…

We explore the integration of societal issues in undergraduate training within the life sciences. Skills in thinking about science, scientific knowledge production and the place of science in society are crucial in the context of the idea of responsible research and innovation. This idea became institutionalized and it is currently well-present in…

Circular dichroism (CD) has emerged as one of the standard biophysical techniques for the study of guaninequadruplex (G4) folding, cation effect, and ligand binding. The utility of this technique is based on its robustness, ease of use, and requirement of only small quantities of nucleic acid. This experiment is also extendable to the classroom…

An integrative laboratory study addressing fundamentals of enzyme catalysis and their application to reactors operation and modeling is presented. Invertase, a ß-fructofuranosidase that catalyses the hydrolysis of sucrose, is used as the model enzyme at optimal conditions (pH 4.5 and 45 °C). The experimental work involves 3 h of laboratory time…

Access to higher education in Portugal is governed by a quota system (numerus clausus). The purpose of this article is to answer two questions: First, how does the "numerus clausus" system shape the demand for medical studies? Second, how do non-enrolled medical candidates influence the global allocation system and generate waves of…

The biochemistry and molecular biology of the extracellular matrix (ECM) is difficult to convey to students in a classroom setting in ways that capture their interest. The understanding of the matrix's roles in physiological and pathological conditions study will presumably be hampered by insufficient knowledge of its molecular structure.…

A multi-method active learning approach (MALA) was implemented in the Medical Biochemistry teaching unit of the Biomedical Sciences degree at the University of Aveiro, using problem-based learning as the main learning approach. In this type of learning strategy, students are involved beyond the mere exercise of being taught by listening. Less…

[beta]-lactamases are hydrolytic enzymes that inactivate the [beta]-lactam ring of antibiotics such as penicillins and cephalosporins. The major diversity of studies carried out until now have mainly focused on the characterization of [beta]-lactamases recovered among clinical isolates of Gram-positive staphylococci and Gram-negative…

Our previous studies have shown that Portuguese primary school pupils and teachers have three main difficulties in the representation of the digestion process: the sequence of the digestive tract, blood absorption, and the relationship of the digestive function with other human functions. In this study we analysed the topic of digestion in 63…

The biochemistry degree has been taught at Lisbon University for 25 years. Since its creation, the curriculum is characterized for being widely eclectic and multidisciplinary. The adoption of the concepts proposed in Europe by the Declaration of Bologna and incorporation of these ideas at Lisbon University is discussed here for the biochemistry…
