Modification de la composition lipidique membranaire chez les bactéries lactiques en conditions de stress : étude du rôle physiologique des Acides Gr…
2010
The results obtained in this work have shown that in both lactic acid bacteria models, L. lactis subsp. cremoris and O. oeni, transcription of the cfa gene, encoding the Cfa synthase is stimulated when cells enter stationary phase of growth or when the cells are grown under stress conditions (acidic or presence of ethanol in the medium). The role of the CFAs has been apprehended by the comparative physiological analysis of the parental strain L. lactis subsp. cremoris and a Δcfa mutant generated in this strain. The high percentages of survival obtained in strains grown at pH 5.0 and undergoing acid stress (pH 3.0) prove that the cyclopropanation of unsaturated fatty acids is not essential t…
The metabolic responses to electrical pulse-induced contractions in C2C12 myotubes are greater in high glucose medium
2021
Osaa liikunnan terveyshyötyjen mekanismeista on vaikeaa tutkia ihmisillä tai koe-eläimillä. Viljeltyjen C2C12 myotuubien sähköpulssistimulaatiolla (EPS, engl. electrical pulse stimulation) voidaan mallintaa lihassupistuksia ja liikuntaa in vitro –olosuhteissa. EPS:n vaikutusta C2C12 myotuubien aineenvaihduntaan ei kuitenkaan tunneta tarkasti. Lisäksi C2C12 myotuubeja viljellään yleensä korkeassa ei-fysiologisessa 25 mM glukoosipitoisuudessa, mikä voi vaikuttaa EPS-vasteisiin. Tässä tutkimuksessa C2C12 myotuubeja sähköpulssistimuloitiin 24 tunnin ajan sekä matalan 5.5 mM (MG) että korkean 25 mM (KG) glukoosipitoisuuden olosuhteissa, ja aineenvaihduntatuotteiden konsentraatiot analysoitiin se…
Composite femoro-tibial bypass as alternative solution in complicated revascolarization: Case report
2021
Introduction Peripheral Arterial Disease (PAD) in diabetic patients is a significant cause of Morbility. Long arterial occlusion in patient previously treated can require unusual and complex solution. Herein we report a case of complicated bypass in diabetic patient with history of bypass for bilateral popliteal aneurysm. Presentation of case A 51-year-old male, smoker, with hypertension and diabetes mellitus was referred to our hospital for rest pain in left limb and peripheral cyanosis. Ultrasound doppler (US) showed an occlusion after common femoral artery with patency of Anterior-tibial artery (ATA) two centimeters after the origin. The unavailability of adequate autologous conduit nece…
Revisiting the “The Breakfast Club”: Testing Different Theoretical Models of Belongingness and Acceptance (and Social Self-Representation)
2021
The current work tests different theoretical models of belongingness and acceptance as fundamental needs for human motivation. In the current study, 372 participants were presented with 52 different items measuring five different theoretical models of belongingness (with a total of 32 items) and three different theoretical models of acceptance (with a total of 20 items). In a first step, Confirmatory Factor Analysis (CFA) failed to provide support for these eight theoretical models. In a second step, we therefore applied Exploratory Factor Analysis yielding three factors, which we interpreted as communicating: (1) Belongingness, (2) Emotion-Acceptance, and (3) Social Self-Representation. In…
