Amphiphilic polymers are a class of polymers that self-assemble into different types of microstructure, depending on the solvent environment and external stimuli. Self assembly structures can exist in many different forms, such as spherical micelles, rod-like micelles, bi-layers, vesicles, bi-continuous structure etc. 2, record 1, English, - amphiphilic%20polymer

Kinesin is a dimeric motor protein that can move for several micrometers along a microtubule without dissociating. The two kinesin motor domains are thought to move processively by operating in a hand-over-hand manner, although the mechanism of such cooperativity is unknown. Recently, a ~50-amino acid region adjacent to the globular motor domain (termed the neck) has been shown to be sufficient for conferring dimerization and processive movement. Based upon its amino acid sequence, the neck is proposed to dimerize through a coiled-coil interaction. To determine the accuracy of this prediction and to investigate the possible function of the neck region in motor activity, we have prepared a serie of synthetic peptides corresponding to different regions of the human kinesin neck and analyzed each peptide for its respective secondary content and stability. 2, record 5, English, - synthetic%20peptide

De nombreux peptides amphiphiles existent dans la nature. Sous forme d’hélice, ils interagissent avec les bicouches lipidiques constituant les membranes cellulaires. En s’appuyant sur ce phénomène biologique, nous avons synthétisé en phase solide un peptide amphiphile contenant 26 acides aminés. C'est un peptide simple, constitué uniquement de deux acides aminés différents. Une chaîne formée de 20 résidus d’alanine constitue la partie hydrophobe et 6 résidus de lysine assurent l'hydrophilicité du peptide. Un tel peptide devrait avoir un comportement comparable aux peptides d’origine naturelle et être capable de s’insérer dans une bicouche lipidique. Nous étudions donc la conformation adoptée par ce peptide par différentes méthodes spectroscopiques telles que le dichroïsme circulaire et l'infra-rouge dans différentes conditions. Nous essayons ainsi de déterminer le pourcentage d’hélices présents dans ce peptide. Le comportement de ce peptide synthétique est comparé à ceux de la polylysine et de la polyalanine dans les mêmes conditions. 2, record 5, French, - peptide%20synth%C3%A9tique

GDNF increases motoneuron survival and cell number, neurite outgrowth and choline acethyltransferase (ChAT) activity (Henderson et al., 1994). The motoneurons can also be rescued from axotomy-induced or natural cell death by GDNF in mouse, rat and avian models (Henderson et al., 1994; Oppenheim et al., 1995). This response is not limited to developing motor neurons, but is also seen in the neurons of adult animals (Li et al., 1995; Yan et al., 1995) supporting the idea of the applicability of GDNF as a potential therapeutic agent in motor neuron diseases, such as amyotrophic lateral sclerosis (ALS), spinal muscular atrophy or in ischemic and mechanic injuries of the spinal cord. 1, record 6, English, - choline%20acethyltransferase

The property of surface activity is usually due to the fact that the molecules of the substance are amphipathic or amphiphilic, meaning that each contains both a hydrophilic and a hydrophobic (lipophilic) group. This assumes that one of the two phases is aqueous, and the other non-aqueous.
