Growth and shortening of microtubules: a two-state model approach.
In this study, a two-state mechanochemical model is presented to describe the dynamic instability of microtubules (MTs) in cells. The MT switches between two states, the assembly and disassembly states. In assembly state, the growth of MTs includes two processes: free GTP-tubulin binding to the tip of protofilament (PF) and conformation change of PF, during which the first tubulin unit that cur...

مطالعات قبلی بازار بیمه را به صورت کلی در نظر می گرفتند اما در این مطالعه صنعت بیمه به عنوان متغیر مستفل به بیمه های زندگی و غیر زندگی شکسته شده و هم چنین بیمه های زندگی به رشته های مختلف بیمه ای که در بازار بیمه ایران سهم قابل توجهی دارند تقسیم میشود. با استفاده از روشهای اقتصاد سنجی داده های برای دوره های 48-89 از مراکز ملی داده جمع آوری شد سپس با تخمین مدل خود بازگشتی برداری همراه با تعدادی ...
15 صفحه اولDynamic Simulation and Mechanical Properties of Microtubules
This work is conducted to obtain mechanical properties of microtubule. For this aim, interaction energy in alpha-beta, beta-alpha, alpha-alpha, and beta-beta dimers was calculated using the molecular dynamic simulation. Force-distance diagrams for these dimers were obtained using the relation between potential energy and force. Afterwards, instead of each tubulin, one sphere with 55 KDa weight ...
متن کاملShort-Term Clinical Outcomes of Radial Shortening Osteotomy and Capitates Shortening Osteotomy in Kienböck Disease
Background: There is no consensus on the best surgical treatment in Kienböck disease. We compared the shortterm outcomes of radial shortening osteotomy and capitate shortening osteotomy in patients affected with this disease. Methods: In a retrospective study of 21 patients with Lichtman stage IIIA of Kienböck disease, 12 patients with an average follow up of 3.2 ± 0.6 years had radial short...
متن کاملAxon growth: roles of microfilaments and microtubules.
The motile tips of elongating axons consist of growth cones from which microspikes protrude. Cytochalasin B causes retraction of microspikes, rounding-up of growth cones, and cessation of axon elongation. Drug withdrawal is followed by resumption of growth cone and microspike activity and of axon elongation. In contrast, colchicine causes shortening and retraction of axons, but it does not init...
