Exposition continue à des mélanges de perturbateurs endocriniens

2012

Dans ce projet, il est question d’explorer les effets de mélanges de perturbateurs endocriniens sur plusieurs générations, en considérant des cibles différentes (appareil reproducteur, glande mammaire, os, dent, tissu adipeux, glandes salivaires, cerveau...) et adaptées à chaque âge pour essayer de mieux comprendre comment agissent des perturbateurs endocriniens, en particulier ceux qui interfèrent avec les hormones sexuelles. Parmi les questions majeures que se pose le scientifique, figurent celles de l’effet d’une exposition prolongée à des mélanges de perturbateurs endocriniens depuis la conception jusqu’à l’âge adulte, et de la possibilité que ces expositions aient des répercussions sur…

Sports and exercise medicine clinic in public hospital settings: A real-life concept and experiences of the treatment of the first 1151 patients

2022

AbstractExercise has been shown to have a multitude of health-promoting effects, including improvements in cardiorespiratory and muscular fitness, function, symptoms and risk factors. Furthermore, exercise may slow down, stop or even reverse the progression of various non-communicable diseases (NCDs). Despite the overwhelming evidence, exercise is still not comprehensively used as a treatment component either in primary care or in hospital settings. The outpatient Sports and Exercise Medicine Clinic (SEMC) is the first specialized clinic in Finland to use exercise as part of patient protocols in the public health care system. Patients needing specialist attention due to NCDs, usually combin…

Effect of doping and crystallite size on the electrochemical performance of Li4Ti5O12

2016

Defect spinel phase lithium titanate (Li4Ti5O12) has been suggested as a promising negative electrode material for next generation lithium ion batteries. Flame spray pyrolysis has been shown to be a viable fast, one-step process for synthesis of nanoparticulate Li4Ti5O12. However, due to the rapid quenching that is integral to the process the crystallite size remain very small and non-uniform. To overcome this shortcoming a vertical flow tube furnace was used to increase the high-temperature residence time. This resulted in an increase in the crystallite size and crystallinity of the product. As a result of this increase the electrochemical performance of the Li4Ti5O12 was markedly improved…

Study of the Effect of Two Phases in Li4SiO4–Li2SiO3 Ceramics on the Strength and Thermophysical Parameters

2022

This research was funded by the Science Committee of the Ministry of Education and Science of the Republic of Kazakhstan (No. BR11765580). The research of the team from Latvia (A.M., V.P. and A.I.P.) has been carried out within the framework of the EUROfusion Consortium, funded by the European Union via the Euratom Research and Training Programme (Grant Agreement No. 101052200—EUROfusion). Views and opinions expressed are however those of the author(s) only and do not necessarily reflect those of the European Union or the European Commission.

Impact of Genetic and Cultural Factors on Extra-Virgin Olive Oil Composition

Phytochemical profile and phototoxicity of eleven Hypericum species extracts

2017

The genus Hypericum (family Hypericaceae) contains 484 species, one of which, Hypericum perforatum, is largely used in medicine as antidepressant, as well as antinflammatory, and antimicrobial agent. Hypericin, together with the other naphthodianthrone derivatives named hypericins (the red pigments recognized as partially responsible for biological activities of this plant), has been identified largely in more than 300 Hypericum species (Skalkos et al., 2006). Particularly, hypericins are one of the most potent naturally occurring photodynamic agents; indeed, upon light irradiation, they very effectively induce apoptosis and/or necrosis of cancer cells (Karioti et al., 2010) and thus might …

Semiconductors: Growth and Characterization

2018

Semiconducting materials are widely used in several applications such as photonics, photovoltaics, electronics and thermoelectrics, because of their optical and electro-optical features. The fundamental and technological importance of these materials is due to the unique physical and chemical properties. Over the years, numerous methods have been developed for the synthesis of high efficient semiconductors. Besides, a variety of approach and characterization methods have been used to study the numerous and fascinating properties of the semiconducting materials. This book collects new developments about semiconductors, from the fundamental issues to the synthesis and applications. Special at…

CulnSe2/Zn(S,O,OH) junction on Mo foil by electrochemical and chemical route for photovoltaic applications

2014

Electrodeposition is a convenient technique for the development of low cost materials for photovoltaic (PV) device processing. Using a single step electrodeposition route, several groups have fabricated CIS (CuInSe) and CIGS (CuInGaSe) films [1]. One of the most important requirements for successful application of one-step electrodeposition film formation, is the ability to control composition of the deposited films and to develop polycrystalline microstructures with a low surface roughness and high sintered density. In this preliminary work, CIS films were produced by single bath electrodeposition finding the optimal conditions in order to achieve a dense film with high crystallinity and u…

Assessment of Physical and Chemical Stability of Different Magnesium Compounds in Tablets

2020

Modern lifestyle, excessive chemicalization of agricultural products, excessive processing and refining of food, cause a decrease in daily intake of magnesium, cation with an extremely important role in prevention and treatment of many diseases. As a result, there arises the need for extra magnesium intake in the form of dietary supplements. In this study were evaluated the physical and chemical stability of magnesium-containing tablets, depending on the active compound and the excipients used. Magnesium tablets in the form of orotate, lactate, citrate, oxide and hydroxide were taken into study and physical and chemical stability were observed over the validity period, at 6 and at 12 month…
