The directional flow of information in neurons depends on compartmentalization: dendrites receive inputs whereas axons transmit them. Axons and dendrites likewise contain structurally and functionally distinct subcompartments. Axon/dendrite compartmentalization can be attributed to neuronal polarization, but the developmental origin of subcompartments in axons and dendrites is less well underst...

objective(s):growing evidence indicates that extract of ginkgo biloba (egb) attenuates hippocampal-dependent memory deficit in aged individuals; however, very little is known about the effect of egb on the structure of hippocampus. therefore we examined the egb-induced morphological changes of the cornu ammonis (ca) region in aged rats. materials and methods: sixteen aged male wistar rats, 24 m...

The class-specific transcription factors Knot and Cut act during dendrite arbor development to define the characteristic dendrite branching pattern of the Drosophila class IV dendritic arborisation sensory neurons. Knot mediates dendrite arbor outgrowth and branching via a microtubule-based program that includes upregulation of the microtubule severing protein Spastin. On the other hand, Cut pr...

Diverse non-equilibrium eutectic structures have attracted numerous experimental and theoretical studies. One special type is the formation of a halo of one phase around a primary dendrite of another phase. In our experiments, it was occasionally observed that ScNi halos grow as dendritic morphology around the primary Sc 2 Ni dendrites in an arc-melted ScNi-Sc 2 Ni off-eutectic binary alloy. Th...

The lithium dendrite and parasitic reactions are two major challenges for (Li) metal anode—the most promising anode materials high-energy-density batteries. In this work, both the that occurred between liquid electrolyte Li-metal could be largely inhibited by regulating Li+-solvation structure. saturated species exist in commonly used LiPF6 needs extra energy to desolvation during Li-electrodep...

Eutectic structures in Ag-based brazing filler metals play an important role improving the properties of alloys and brazed joints. The typical microstructures morphological evolution Ag-Cu eutectic solidified at various cooling rates with addition different Sn contents were investigated. formation mechanisms anomalous structure (AES) transition from lamellar (LES) to AES elucidated. a slow rate...
