The potential sustainable development of health-related tourism in Libya and its influence on the European tourist's attraction : a study in touristi…

2017

This study focuses on sustainable development potential in the health tourism industry in Libya. It attempts to explain the difference between medical tourism and health tourism, for which the country’s natural and human resources are a veritable wealth. Our research begins with the realisation that health tourism in Libya may contribute to the economic development of the country and participate in long-term sustainable development inasmuch as it has fewer negative effects on the environment and the population. Indeed, for the last 54 years the Libyan economy has been dependent on oil. For this reason and others, we believe that sustainable development in the health tourism field is one of …

Cortical taste activity in response to sucrose and sweeteners solutions: a study using gustatory evoked potential

2016

Introduction: Sweeteners are widespread in overweight or diabetic patients because of their high sweetening power and their light effect on glycaemia. Sweeteners effects on cortical activity, reflecting both cortical analysis and gustatory signalization pathway, are not well known. We observed previously that gustatory evoked potentials (GEPs) in response to sucrose varied in latency and/or in amplitude with sucrose concentration of the solution, the pleasantness of taste and the feeding status. The aim was to compare the gustatory cortical activity by recording GEPs in response to sucrose, aspartame and stevia solutions.Methods: Twenty healthy non-smoker adult volunteers were included (mea…

Etude du contrôle hédonique de la prise alimentaire par l'analyse des potentiels évoqués gustatifs

2016

Hedonic control of food intake has been studied using neurophysiological investigations in animals and functional imaging in humans. Gustatory evoked potentials (GEPs), a higher time resolution technique than functional imaging, have never been used for this purpose. The first aim of this thesis was to establish a reliable recording of GEPs in humans, in response to a sapid stimulus. The second aim was to determine the GEPs modifications according to the hedonic value of food intake. GEPs recording was performed in response to an intermittent stimulation of a sapid solution in more than 100 young healthy subjects. The comparisons between cerebral recordings in response to water or paraffin …

Electronic implementation of a non-linear oscillator subjected to noise : application to the modeling of neuronal information coding

2011

We study the nonlinear FitzHugh-Nagumo model witch describes the dynamics of excitable neural element. It is well known that this system exhibits three different possible responses. Indeed, the system can be mono-stable, oscillatory or bistable. In the oscillatory regime, the system periodically responds by generating action potential. By contrast, in the mono-stable state the system response remains constant after a transient. Under certain conditions, the system can undergo a bifurcation between the stable and the oscillatory regime via the so called Andronov-Hopf bifurcation. In this Phd thesis, we consider the FitzHugh-Nagumo model in the stable state, that is set near the Andronov-Hopf…

Elaboration of a list of substances of interest as regards to a potential endocrine activity and prioritisation strategy for assessment

2021

Endocrine Disruptor Chemicals (EDCs) are substances that alter function(s) of the endocrine system and consequently cause adverse health effects. The endocrine system consists of many cells and tissues that interact with each other and the rest of the body by means ofhormones. This system is responsible for controlling a large number of processes in the body from gamete formation, to conception and early developmental processes such as organogenesis, and to most tissue and organ functions throughout life. EDCs interfere withendocrine function by many ways and, in doing so, lead to adverse effects on the health of humans and/or wildlife. Some of the observed health effects associated with ED…
