Abstract

La matière active, dans les bonnes conditions, peut servir à transporter des objets dans son environnement. Nous étudions ainsi la motilité d'une superstructure composée d'une membrane enfermant des particules actives capables d'auto-organisation. Nous identifions les facteurs indispensables à sa mise en mouvement ainsi que ceux menant à sa motilité optimale. Les paramètres d'alignement, de densité et de rigidité de la membrane sont investigués, et nous trouvons qu'une combinaison des deux premiers favorise le déplacement de la superstructure. L'amorce de ce dernier est dû à l'existence d'une brisure de symétrie dans la distribution des particules formant des amas et nous assimilons ce phénomène au démon de Maxwell granulaire. Une telle étude offre à la fois des possibilités d'édification de technologies autonomes et intelligentes, et des aperçus sur la dynamique de migration d'une cellule biologique.

Abstract

Cell motility is a fascinating example of cell behavior which is fundamentally important to a number of biological and pathological processes. It is based on a complex self-organized mechano-chemical machine consisting of cytoskeletal filaments and molecular motors. In general, the cytoskeleton is responsible for the movement of the entire cell and for movements within the cell. The main challenge in the field of cell motility is to develop a complete physical description on how and why cells move. For this purpose new ways of modeling the properties of biological cells have to be found. This long term goal can only be achieved if new experimental techniques are developed to extract physical information from these living systems and if theoretical models are found which bridge the gap between molecular and mesoscopic length scales. Cell Motility gives an authoritative overview of the fundamental biological facts, theoretical models, and current experimental developments in this fascinating area.

Abstract

This Special Issue covers both the in vitro and in vivo evaluation of marine carotenoids with anti-inflammatory and anticancer activities as well as clinical trials conducted in humans. Among the properties of carotenoids discussed in this book, it is worth highlighting the potential of astaxanthin and its precursor metabolite, adonixanthin, since oral administration of these carotenoids has shown beneficial effects on glioblastoma for the first time by suppressing cell proliferation and migration. In addition, astaxanthin has been shown to inhibit Helicobacter pylori-induced gastric carcinoma cell motility and, consequently, cancer progression through the inhibition of cytoskeleton reorganization. In addition, a carotenoid-containing lipid extract of Gloeothece sp. has demonstrated antioxidant, anti-inflammatory, and anticancer properties in vitro.
