The study explores whether racial identity and appearance-based trustworthiness judgments can affect recognition of pain in medical students differing in levels of resting heart rate variability (HRV), a measure of parasympathetic control of the heart. After undergoing HRV assessment, 68 medical students (37 females) participated in a dynamic pain…

The purpose of this study is to determine the effect of 8 weeks of HRV (Heart Rate Variability) training on the happiness and coherence levels of university students. According to this purpose, 20 sports management students from the same class volunteered to participate in the study. 10 students were selected randomly as the experimental group…

Medical personnel often experience stress when responding to a medical emergency. A known stress-response is a measurable reduction in heart rate variability. It is currently unknown if crisis simulation can elicit the same stress response as real clinical emergencies. We aim to compare heart rate variability changes amongst medical trainees…

Games and analogies can significantly enrich the learning experience when integrated with traditional expository teaching methods. With this aim, we developed "The Mystery of the Cell Kingdom," an online game designed to enhance understanding of the physiology of thyroid hormones through a medieval analogy. In the game, students are…

Anaerobic respiration reactions are of fundamental importance to global biogeochemical cycling of elements. Yet, the idea that cellular respiration can occur not only in the absence of oxygen but also involve the oxidation of inorganic substrates (e.g., AsO[subscript 3 superscript 3-], Fe[superscript 2+], H[subscript 2], H[subscript 2]S,…

Objective: To examine the association of CRF and adiposity with cardiometabolic risk factors and metabolic syndrome among emerging adults. Participants: 5681 (60.1% Men; 21 ± 1years) college students from a large university located in the northeast of the United States. Methods: Participants completed an objective health assessment that involved…

Math anxiety (MA) is an important affective factor that contributes to individuals' math proficiency. While self-reports are commonly used to measure MA, a number of limitations are inherently connected to this measuring method. Physiological responses are considered a promising alternative approach, but research is scarce and the empirical…

Objective: Impaired sleep is associated with insulin resistance (IR), a precursor to type 2 diabetes mellitus (T2DM), but is poorly understood in young adults. This cross-sectional study examined sleep characteristics, risk factors for T2DM, and IR in college students. Participants: Thirty-two college students (18--25 years) with either short…

As a rule, an experiment carried out at school or in undergraduate study courses is rather simple and not very informative. However, when the experiments are to be performed using modern methods, they are often abstract and difficult to understand. Here, we describe a quick and simple experiment, namely the enzymatic characterization of ptyalin…

The objective of the present study was to investigate whether class participation correlates with academic performance in a biochemistry and metabolism course for first-year veterinary school students. To increase engagement in this course, students had the opportunity to answer Poll Everywhere questions during many lectures in the course. These…

The present study was to teach metabolic syndrome (MetS) disease through a scenario developed according to the problem-based learning (PBL) approach in the biochemistry class. The study was designed as a single group pre-test and post-test research. The study group consisted of first-year students (N = 183) from the nursing department within the…

Subtle instructional changes that direct attentional focus can lead to changes in performance, potentially hindering a fitness assessment. An external attentional focus has been found to improve motor performance, however less is known about instructional effects on performance and the physiological response during an isometric endurance test. To…

Purpose: Hands-on training in tissue engineering is often associated with specialized labs and expensive equipment, such as CO[subscript 2] incubators. To minimize the use of costly commercial incubators and provide a more vivid engineering experience in a biology lab, we present a hands-on project that introduces medium to large groups of…

In this work extensive misconceptions of university students'--from nutrition area--about the metabolism of carbohydrates (CHM) in the human organism have been documented. The results lead to consider their difficulties concerning the learning of a complex set of imbricated biochemical models involved. Pursuant to these considerations, three…

Plant metabolite compounds have been applied on plant cellular metabolism, produces organic and inorganic compounds, primary and secondary bioactive molecules, such as glucose, amino acids, fat acids, alkaloids, flavonoids, and terpenoids. Undergraduate biology students learn about the plant terpenoid assisted by bioinformatics to store, manage,…
