Saccharomyces cerevisiaeSaccharomyces cerevisiae est une espèce de levures employée notamment dans la fermentation de la bière. Elle occupe une place particulière parmi les ferments, levains et levures utilisés depuis la Haute Antiquité : de nombreux peuples, tels que les Égyptiens, Babyloniens ou Celtes, l’utilisaient pour la fabrication de boissons fermentées, du pain, du kéfir, du vin et de la bière de fermentation haute.
Attachment therapyAttachment therapy (also called "the Evergreen model", "holding time", "rage-reduction", "compression therapy", "rebirthing", "corrective attachment therapy", and "coercive restraint therapy") is a pseudoscientific child mental health intervention intended to treat attachment disorders. It is found primarily in the United States, and much of it is centered in about a dozen clinics in Evergreen, Colorado, where Foster Cline, one of the founders, established his clinic in the 1970s.
Protein filamentIn biology, a protein filament is a long chain of protein monomers, such as those found in hair, muscle, or in flagella. Protein filaments form together to make the cytoskeleton of the cell. They are often bundled together to provide support, strength, and rigidity to the cell. When the filaments are packed up together, they are able to form three different cellular parts. The three major classes of protein filaments that make up the cytoskeleton include: actin filaments, microtubules and intermediate filaments.
Attachment in childrenAttachment in children is "a biological instinct in which proximity to an attachment figure is sought when the child senses or perceives threat or discomfort. Attachment behaviour anticipates a response by the attachment figure which will remove threat or discomfort". Attachment also describes the function of availability, which is the degree to which the authoritative figure is responsive to the child's needs and shares communication with them.
Spindle pole bodyThe spindle pole body (SPB) is the microtubule organizing center in yeast cells, functionally equivalent to the centrosome. Unlike the centrosome the SPB does not contain centrioles. The SPB organises the microtubule cytoskeleton which plays many roles in the cell. It is important for organising the spindle and thus in cell division. The molecular mass of a diploid SPB, including microtubules and microtubule associated proteins, is estimated to be 1–1.5 GDa whereas a core SPB is 0.3–0.5 GDa.
VimentineLa vimentine est une protéine, membre de la famille des filaments intermédiaires. Les filaments intermédiaires sont des protéines structurelles importantes des cellules eucaryotes. Ils constituent, avec les microtubules et les microfilaments d'actine, le cytosquelette. Bien que la plupart des filaments intermédiaires soient des structures stables, dans les fibroblastes, la vimentine est une structure dynamique. Un monomère de vimentine, comme tous les autres filaments intermédiaires, a un domaine en hélice alpha, avec à chaque extrémité des têtes aminées non-hélicoïdales et des queues carboxylées.
Mating of yeastThe yeast Saccharomyces cerevisiae is a simple single-celled eukaryote with both a diploid and haploid mode of existence. The mating of yeast only occurs between haploids, which can be either the a or α (alpha) mating type and thus display simple sexual differentiation. Mating type is determined by a single locus, MAT, which in turn governs the sexual behaviour of both haploid and diploid cells. Through a form of genetic recombination, haploid yeast can switch mating type as often as every cell cycle. S.
Levure en vinification300px|vignette|Fermentation alcoolique lors de la vinification. Lorsque les levures consomment le sucre du moût, elles produisent de l'éthanol et du dioxyde de carbone. Ce gaz forme des bulles dans la cuve et mousse à la surface. Le rôle des levures en vinification est l'élément clé de la fermentation. Il permet de transformer le moût en vin. Les levures transforment les sucres du raisin, principalement en éthanol et en dioxyde de carbone.
Filament intermédiaireLes filaments intermédiaires ont une dimension intermédiaire (de 8 à 12 nm) entre les filaments fins d'actine et les microtubules formant à eux trois, le cytosquelette. Décrits d'abord dans les muscles, ce sont les structures les plus stables du cytosquelette. En effet, les traitements dissolvant les microtubules et les microfilaments laissent apparaître le réseau de filaments intermédiaires. De plus, ces structures semblent ne pas être désassemblées aussi souvent que les microtubules et les microfilaments.
Dynamic-maturational model of attachment and adaptationThe dynamic-maturational model of attachment and adaptation (DMM) is a biopsychosocial model describing the effect attachment relationships can have on human development and functioning. It is especially focused on the effects of relationships between children and parents and between reproductive couples. It developed initially from attachment theory as developed by John Bowlby and Mary Ainsworth, and incorporated many other theories into a comprehensive model of adaptation to life's many dangers.
