Langevin dynamics simulations are performed on linear-dendritic diblock copolymers containing bead-spring, freely jointed chains composed of hydrophobic linear monomers and hydrophilic dendritic monomers. The critical micelle concentration (CMC), micelle size distribution, and shape are examined as a function of dendron generation and architecture. For diblock copolymers with a linear block of ...

The work described here focuses on novel patterns of motoneuron dendritic organization and dendritic development in relation to the recruitment patterns of spinal motoneurons that drive swimming in larval zebrafish. I first looked at the dendritic organization of motoneurons in freely swimming fish and tracked its emergence in relation to the maturation of locomotor behavior. I used transient e...

variety of positive as well as negative regulatory signals are provided by antigen presenting cell in particular by dendritic cells. in this research, we studied the capacity of dendritic cells to expand antigen-specific t regulatory cells.we also investigated the role of tgf-beta in induction inhibitory functions of dendritic cells in mixed leukocyte reactions. dendritic cells were generated f...

In this paper, AlxCoFe1.9Ni2.1 (x = 0.5, 0.8, 1.0, 1.5) high entropy alloys are prepared by vacuum arc melting furnace. The effect of aluminum content on the microstructure and mechanical properties was studied. alloy characterized SEM, X-ray diffraction EDS. results show that with increase content, varies from FCC to FCC+BCC structure finally single BCC structures. And when is exhibits slender...

background: tumor necrosis factor alpha (tnf-α) is a primary mediator of immune regulation and might be required in the early stages of dc development from cd34+ cells. however, details of optimal timing of exposure to tnf-α in dc development process in monocytes or non-purified hematopoitic cells are still lacking and clear benefits of this approach to the development of dcs remain to be valid...

In the retina of teleost fish, continuous neuronal development occurs at the margin, in the peripheral growth zone (PGZ). We prepared tissue slices from the retina of rainbow trout that include the PGZ and that comprise a time line of retinal development, in which cells at progressive stages of differentiation are present side by side. We studied the changes in dendritic structure and voltage-d...
