Co-construction et appropriation des savoirs en EPS et stratégies de management identitaire
2010
Les mécanismes psycho-sociologiques relatifs aux interactions groupales influent sur l'appropriation d'un savoir en EPS. Ainsi, les théories de l'identité sociale (Tajfel & Turner, 1986) et de l'auto-catégorisation (Oakes, Haslam & Turner, 1994) montrent que l'individu peut se définir en fonction de ses appartenances groupales. Ces positionnements sociaux émergent quand un ensemble humain est divisé en sous-groupes ; l'apparition chez l'individu de diverses distorsions (perception, évaluation, comportement) favorise son groupe (endogroupe) et peut être préjudiciable à un groupe extérieur (exogroupe). Les "stratégies de management identitaire" (Ellmers, 1993) permettent à l'individu de conse…
Microhydrological Niches in Soils: How Mucilage and EPS Alter the Biophysical Properties of the Rhizosphere and Other Biological Hotspots
2019
Plant roots and bacteria are capable of buffering erratic fluctuations of water content in their local soil environment by releasing a diverse, highly polymeric blend of substances (e.g. extracellular polymeric substances [EPS] and mucilage). Although this concept is well accepted, the physical mechanisms by which EPS and mucilage interact with the soil matrix and determine the soil water dynamics remain unclear. High-resolution X-ray computed tomography revealed that upon drying in porous media, mucilage (from maize [Zea mays L.] roots) and EPS (from intact biocrusts) form filaments and two-dimensional interconnected structures spanning across multiple pores. Unlike water, these mucilage a…
Immunosenescence and lymphomagenesis
2018
Abstract One of the most important determinants of aging-related changes is a complex biological process emerged recently and called “immunosenescence”. Immunosenescence refers to the inability of an aging immune system to produce an appropriate and effective response to challenge. This immune dysregulation may manifest as increased susceptibility to infection, cancer, autoimmune disease, and vaccine failure. At present, the relationship between immunosenescence and lymphoma in elderly patients is not defined in a satisfactory way. This review presents a brief overview of the interplay between aging, cancer and lymphoma, and the key topic of immunosenescence is addressed in the context of t…
Trial profile: pilot study of the multicentre randomised trial of H. pylori eradication and pepsinogen testing for prevention of gastric cancer morta…
2019
Purpose: The GISTAR Pilot study is part of a large multi-centre randomised trial conducted in Latvia with the main aim to evaluate preventive strategies to decrease mortality from gastric cancer in high-risk areas, especially in the Baltic States and Eastern Europe. Participants: A total of 3,447 apparently healthy, asymptomatic participants (40-64 y/o) were recruited between 2013 and 2015 for the GISTAR pilot study. Participants were interviewed for socio-economic status, lifestyle, environmental and occupational exposures, medical history, family history of diseases, and dietary habits. Participants were randomly assigned to either Intervention (n=1,724) or Control (n=1,723) group. The in…
Could Low-Frequency Electromyostimulation Training be an Effective Alternative to Endurance Training? An Overview in One Adult
2014
This preliminary study aimed to investigate the effects of a six-week low-frequency electromyostimulation training (10Hz) on the cardiovascular, respiratory and muscular systems. To that purpose, aerobic capacity, knee extensor muscles strength and architecture, muscle sympathetic nervous activity, blood pressure and heart rate have been evaluated in one healthy male subject (33 year-old, 1.73 m, 73 kg). Results showed improvement of aerobic capacity (+4.5% and +11.5% for maximal oxygen uptake and ventilatory threshold) and muscle strength (+11% and +16% for voluntary and evoked force). Moreover, for the first time, this study demonstrated low-frequency training effects on muscle architectu…
Early Steps -liikuntaohjelman yhteydet 4-5-vuotiaiden päiväkotilasten motoristen perustaitojen kehitykseen
2008
Fundamental motor skills (FMS) are necessary skills for children to cope with their daily lives and to acquire a physically active lifestyle. Researchers have recommended that preschool-age children participate in a developmentally appropriate practice of balance, locomotor and manipulative skills for the promotion of their FMS.The purpose of this study was to examine the following questions: 1) Does an international Early Steps preschool physical education curriculum (PEC) (Zachopoulou et al. 2007) which lasts eight months have any effects on the FMS development of 4-5-year-old girls and boys in the time of one year? 2) How do the FMS of the 4-5-year-old girls and boys develop in one year?…
Pairwise and higher-order measures of brain-heart interactions in children with temporal lobe epilepsy
2022
Abstract Objective. While it is well-known that epilepsy has a clear impact on the activity of both the central nervous system (CNS) and the autonomic nervous system (ANS), its role on the complex interplay between CNS and ANS has not been fully elucidated yet. In this work, pairwise and higher-order predictability measures based on the concepts of Granger Causality (GC) and partial information decomposition (PID) were applied on time series of electroencephalographic (EEG) brain wave amplitude and heart rate variability (HRV) in order to investigate directed brain-heart interactions associated with the occurrence of focal epilepsy. Approach. HRV and the envelopes of δ and α EEG activity re…
Effects of Long-Term Physical Activity and BCAA Availability on the Subcellular Associations between Intramyocellular Lipids, Perilipins and PGC-1&al…
2023
Cellular skeletal muscle lipid metabolism is of paramount importance for metabolic health, specifically through its connection to branched-chain amino acids (BCAA) metabolism and through its modulation by exercise. In this study, we aimed at better understanding intramyocellular lipids (IMCL) and their related key proteins in response to physical activity and BCAA deprivation. By means of confocal microscopy, we examined IMCL and the lipid droplet coating proteins PLIN2 and PLIN5 in human twin pairs discordant for physical activity. Additionally, in order to study IMCLs, PLINs and their association to peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) in cytosolic…
Lipodepsipeptides from Pseudomonas syringae are partially proteolyzed and are not absorbed by humans: An in vitro study
2008
There are some concerns about the use of Pseudomonas-based products as biocontrol agents because of the hemolytic activity shown by their metabolites. The effects of Pseudomonas lipodepsipeptides (LDPs) on mammals via ingestion and the LDP degradation during the digestion and intestinal permeability have not been evaluated. In this research, the susceptibility of different LDPs to degradation was assayed with enzymatic gastrointestinal digestion, and intestinal permeability to LDPs was investigated in an in vitro system based on an intestinal cell layer system. Results demonstrated that trypsin and chymotrypsin hydrolyze up to 50% of the various LDPs, and that proteolysis was further increa…
The Value of a Complete Blood Count (CBC) for Sepsis Diagnosis and Prognosis.
2021
Sepsis represents an important global health burden due to its high mortality and morbidity. The rapid detection of sepsis is crucial in order to prevent adverse outcomes and reduce mortality. However, the diagnosis of sepsis is still challenging and many efforts have been made to identify reliable biomarkers. Unfortunately, many investigated biomarkers have several limitations that do not support their introduction in clinical practice, such as moderate diagnostic and prognostic accuracy, long turn-around time, and high-costs. Complete blood count represents instead a precious test that provides a wealth of information on individual health status. It can guide clinicians to early-identify …
