Ambulatory Assessment of Skin Conductivity During First Thesis Presentation: Lower Self-Confidence Predicts Prolonged Stress Response
Applied Psychophysiology and Biofeedback, 2011Co-Authors: Achim Elfering, Simone GrebnerAbstract:In this field study self-confidence was tested to predict the course of galvanic electrodermal stress Response prior, during and after public speaking. Ten graduate students initially rated their self-confidence and afterwards presented their thesis proposals orally in a 10-min presentation to their supervisor and peers. Galvanic skin Response level was measured throughout and analysed for 10 min prior to, during, and 10 min after the presentation. Two major galvanic electrodermal stress Response types were observed. Five students showed a ‘Healthy Response’, i.e. an anticipatory increase in electrodermal conductance, followed by a decrease after termination of the presentation. The other five students showed a steady increase of skin conductance during and after their presentation (‘prolonged Response’). In line with the allostatic load model the ‘prolonged Response’ group reported significantly lower self-confidence before presentation than the ‘Healthy Response’ group ( p

Self-confidence is a resource in novices facing an unfamiliar stressor.

Impact of prolonged fasting on insulin secretion, insulin action and hepatic versus whole-body insulin secretion disposition indices in Healthy young males.
American journal of physiology. Endocrinology and metabolism, 2020Co-Authors: Sine Wanda Jørgensen, Line Hjort, Linn Gillberg, Louise Justesen, Sten Madsbad, Charlotte Brøns, Allan VaagAbstract:The extent to which reduced insulin secretion during prolonged fasting reflects failure to compensate for whole-body insulin resistance or a normal adjustment to potentially increased hepatic insulin action is unknown. We examined the effects of 36 versus 12 h fasting on insulin secretion and whole-body versus hepatic insulin action in 13 Healthy young males. Hepatic glucose production and insulin action was studied using stable isotopes, whereas whole-body insulin action and insulin secretion was studied using an intravenous glucose tolerance test (IVGTT) and minimal modelling. Insulin, glucose and lipid profiles were subsequently measured during a refeeding meal-test. Prolonged fasting caused a minor reduction of first-phase insulin secretion in a context of improved hepatic insulin action contrasting an increase in whole-body insulin resistance. Accordingly, prolonged fasting was associated with opposite directed effects on hepatic versus whole-body insulin secretion disposition indices. Thirty-six compared with 12 h fasting was associated with increased plasma insulin levels during the refeeding meal test. In conclusion, reduced insulin secretion during prolonged fasting may represent a Healthy Response to improved hepatic insulin action. Use of insulin secretion disposition indices without taking organ specific insulin action into account may lead to erroneous conclusions.

A mathematical model to study resistance and tolerance to infection at the animal and population levels: application to E. coli mastitis
Frontiers in genetics, 2012Co-Authors: Johann DetilleuxAbstract:A mathematical model is proposed that describes the colonization of host tissues by a contagious pathogen and the early nonspecific immune Response, the impact of the infection on the performances of the host, and the spread of the infection in the population. The model obeys specific biological characteristics: Susceptible hosts are infected after contact with an infected one. The number of pathogenic units that invade a susceptible host is dependent on the infectious dose provided by the infected host and on the ability of the susceptible host to resist the invasion. After entry in host, pathogenic changes over time are expressed as the difference between the intrinsic logistic growth rate and the Holling type II kill rate provided by the immune Response cells. Hosts have different ability to restrict reproduction of the pathogen units. The number of Response cells actively recruited to the site of infection depends on the number of the pathogenic units. Response cells are removed after having killed a fixed number of pathogenic units. The effects of the number of pathogenic units on the performances of the host depend upon its levels of tolerance to the deleterious effects of both pathogenic and Response cells. Pre-infection costs are associated to tolerance and resistance levels. Estimates of most biological parameters of the model are based on published experimental studies while resistance/tolerance parameters are varied across their allowable ranges. The model reproduces qualitatively realistic outcomes in Response to infection: Healthy Response, recurrent infection, persistent infectious and non-infectious inflammation, and severe immunodeficiency. Evolution across time at the animal and population levels is presented. Effects on animal performances are discussed with respect to changes in resistance/tolerance parameters and selection strategies are suggested.
