Games are highly appreciated by the population, so due to the COVID-19 pandemic confinement we decided to carry out an Internet research of several games, in order to use them for the assimilation of new words of Biochemical students. Games found in puzzle books allow the stimulation of memory, reasoning and other brain capacities, such as keeping…

For centuries we have been using food for our well-being and health maintenance. As far back as Hippocrates (known as the father of medicine), food has been a center stone used as the good or suffering of humanity. The Bible references food and fasting, cleansing and revitalization to heal the spirit. Before the scientific discovery of synthetic…

Living cells are crowded. The presence of so many macromolecules packed into a confined environment affects the structure and function of biological components, and the kinetics and thermodynamics of biochemical reactions. In fact, crowding studies have already led to important biological insights, such as the existence of metabolons and other…

Two-stage collaborative testing is an assessment strategy that involves students initially writing a test individually and then immediately afterward writing the same (or similar) test again in groups. Current evidence shows that two-stage testing improves performance on multiple-choice tests as well as short-term retention of material, but little…

The bibliometric analysis of the Brazilian periodical "Journal of Biochemistry Education" (JBE) covered the 117 articles published in 15 volumes in the period 2001-2017. Our results showed a positive trend in JBE publications with a significant increase in the number of articles since 2014, which can be related to the increase in…

A laboratory experiment introducing the concept of chemical bioconjugation of proteins to undergraduate students in a therapeutically relevant context was developed. Initially, students installed an aldehyde functionality into a protein via the oxidation of the N-terminal threonine residue of the cholera toxin subunit B (CTB) protein, which was…

Introductory biochemistry courses are often challenging for students because they require the integration of chemistry, biology, physics, math, and physiology knowledge and frameworks to understand and apply a large body of knowledge. This can be complicated by students' persistent misconceptions of fundamental concepts and lack of fluency with…

In toddlers, the transition from home to childcare might elicit high levels of the stress hormone cortisol. Measuring cortisol may give an indicator for children's experience and hence, may help improve this transition. We applied linear mixed model analyses to investigate the cortisol levels of 119 toddlers during their transition to childcare…

Many large, undergraduate science courses, which still heavily rely on traditional lecture-based dissemination of content, passive learning, and exam-based assessments, have been forced online due to the COVID-19 pandemic. To address the challenges facing students in regards to engagement, self-directed learning, and the development of soft…

The use of a molecular viewer to visualize proteins has become more prevalent in high schools in recent years. We relied on the foundations of two theoretical frameworks to analyze questions in two learning tasks designed for 10th- to 12th-grade biotechnology majors that make use of Jmol. The two theoretical frameworks were: (i) classification of…

A laboratory exercise was developed for the study of the effect of three cations (Al, Ca, and Na) on the flocculation and dispersion of soil particles. The exercise was designed for Soil Science undergraduate students in the second-course in the Agricultural Engineering and Environmental Sciences department at the University of Vigo. The students'…

In this study, we explore the mechanistic relationship between growth factor signaling and kinase activity that supports the protein synthesis-dependent phase of long-term memory (LTM) consolidation for sensitization of "Aplysia." Specifically, we examine LTM for tail shock-induced sensitization of the tail-elicited siphon withdrawal…

The ability of the ventral hippocampus (VH) for long-lasting long-term potentiation (LTP) and the mechanisms underlying its lower ability for shortlasting LTP compared with the dorsal hippocampus (DH) are unknown. Using recordings of field excitatory postsynaptic potentials (EPSPs) from the CA1 field of adult rat hippocampal slices, we found that…

Anticipated learning outcomes (LOs) were defined and used for the backward design of a Course-based Undergraduate Research Experience (CURE). These LOs reflect the inquiry-based nature of CUREs and capture key knowledge and skills inherent to scientific practice and essential in research. The LOs were used to plan a formative and summative…

This research investigated the effect of problem-based learning (PBL) for the topic of "energy metabolism" in a biochemistry course on the academic achievements of students studying in the healthcare field in a nursing department. The study had a one-group pre-test and post-test research design. The study group consisted of first-year…
