A dynamic bacterial cytoskeleton.
Actin and tubulin are the major components of the cytoskeleton that pervades the cytoplasm of all eukaryotic cells. These proteins were traditionally thought not to be present in prokaryotes, but structural and functional homologues of tubulin (FtsZ) and actin (MreB) are now known to be present virtually throughout the eubacteria and in some archae. FtsZ protein is a key player in cell division...
متن کاملCytoskeleton dynamics
Four of six talks in the Cytoskeleton Dynamics Minisymposium described work on filament end-binding proteins: a reflection of the central role they play in cytoskeletal organization. Scott Hansen's single-molecule study of purified vasodilator-stimulated phosphoprotein (VASP) demonstrated that it is a weakly processive actin polymerase that is targeted to filament ends by actin monomers. Hansen...
متن کاملdynamic coloring of graph
در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...
15 صفحه اولChiral dynamics with strange quarks
In the first part of the talk, I review what we know (or rather do not know) about the structure of the QCD vacuum in the presence of strange quarks. Chiral perturbation theory allows to study reactions of pions and kaons and to further sharpen our understanding of symmetry violation in QCD. I review recent progress on the description of pion-kaon scattering, in particular concerning isospin vi...
متن کاملDynamic imaging of neuronal cytoskeleton.
Growth cones are the motile tips of growing axons. During development growth cones guide axons along specific pathways to appropriate targets by extending toward or retracting away from attractive or inhibitory guidance cues in their environment. Growth cone motility as well as extension, retraction, and turning behaviors are directed by the neuronal cytoskeleton, principally actin filaments an...
