1. Words of advice: teaching enzyme kinetics

Author:
Srinivasan, Bharath
Source:
TheFEBS journal 2021 v.288 no.7 pp. 2068-2083
ISSN:
1742-464X
Subject:
experimental design,   etc   ; enzyme kinetics; enzymes;     Show all 3 Subjects
Abstract:
... Enzymology is concerned with the study of enzyme structure, function, regulation and kinetics. It is an interdisciplinary subject that can be treated as an exclusive sphere of exhaustive inquiry within mathematical, physico‐chemical and biological sciences. Hence, teaching of enzymology, in general, and enzyme kinetics, in particular, should be undertaken in an interdisciplinary manner for a holis ...

Abstract:
... As environmental concerns do not translate into action, this study uses an experimental design to test the effectiveness of different priming strategies in terms of increasing green non‐purchase behaviour frequency. Green non‐purchase behaviours are particularly problematic as they are associated with sacrifice. While previous research focused on promoting green purchases, this research contribute ...

Abstract:
... The recent discussion on the reproducibility of scientific results is particularly relevant for preclinical research with animal models. Within certain areas of preclinical research, there exists the tradition of repeating an experiment at least twice to demonstrate replicability. If the results of the first two experiments do not agree, then the experiment might be repeated a third time. Sometime ...

Abstract:
... Measuring the dietary intakes of individuals for research and monitoring purposes is notoriously challenging and is subject to both random and systematic measurement error. In this review, the strengths and limitations of current methods to assess dietary and supplemental exposures are described. Traditional methods of dietary assessment include food records, food frequency questionnaires, 24-hour ...

Abstract:
... Predator functional responses describe predator feeding rates and are central to predator–prey theory. Ecologists have measured thousands of predator functional responses using the same basic experimental method. However, this design is ill‐suited to address many current questions regarding functional responses. We derive a new experimental design and statistical analysis that quantifies functiona ...

Abstract:
... Before starting any (animal) research project, review of the existing literature is good practice. From both the scientific and the ethical perspective, high-quality literature reviews are essential. Literature reviews have many potential advantages besides synthesising the evidence for a research question. First, they can show if a proposed study has already been performed, preventing redundant r ...

Abstract:
... The study of free‐living populations is important to generate knowledge related to the epidemiology of disease and other health outcomes. These studies are unable to provide the same level of control as is possible in laboratory studies and thus are susceptible to certain errors. The primary categories of study errors are random and systematic. Random errors cause imprecision and can be quantified ...
