Towards Polymer Composite‐Based Transient Electronic Systems

open access: yesAdvanced NanoBiomed Research, EarlyView.
Biodegradable electronic systems are gaining attention for implantable biomedical applications, targeting disease treatment and lifespan extension. This review covers advances in biocompatible, biodegradable polymer composites using synthetic and natural polymers with conductive, semiconductive, and insulating fillers.

Identification of the Micro‐Ribonucleic Acid Profiles of Plant‐Derived Extracellular Vesicles and their Potential Crosskingdom Regulation

open access: yesAdvanced NanoBiomed Research, EarlyView.
The present study employs small RNA sequencing to identify the types and content of microRNAs (miRNAs) in four widely utilized plant‐derived extracellular vesicles (pEVs). The functional annotation reveals that the pEV miRNAs are involved in regulating the progression of human cancer and viral infection, thereby demonstrating the crosskingdom ...

Bioimaging of sense organs and the central nervous system in extant fishes and reptiles in situ: A review

open access: yesThe Anatomical Record, EarlyView.
Bioimaging of the sense organs and brain of fishes and reptiles. Left panel: 3D reconstruction of the head and brain of the deep‐sea viperfish Chauliodus sloani following diceCT. Right panel: A 3D reconstruction of a 70‐day‐old embryo head of the bearded dragon Pogona vitticeps following diceCT, showing the position of the segmented brain within the ...

Axonal shortening and the mechanisms of axonal motility

Cell Motility, 1988
AbstractAxons in tissue culture retract and shorten if their tips are detached from the substrate. The shortening reaction of the axon involves contractile forces that also arise during normal axonal motility, elongation, and retraction. We studied shortening in axonal segments isolated from their parent axons by transecting the axon between the growth

Fast Axonal Transport in Squid Giant Axon

Science, 1982
Video-enhanced contrast-differential interference contrast microscopy has revealed new features of axonal transport in the giant axon of the squid, where no movement had been detected previously by conventional microscopy. The newly discovered dominant feature is vast numbers of "submicroscopic" particles, probably 30- to 50-nanometer vesicles and ...

Axonal transport of lipid in goldfish optic axons

Neurochemical Research, 1978
After injection of labeled glycerol, choline, or serine into the eye of goldfish, labeled lipids were axonally transported along the optic nerve to the optic tectum. Although the different precursors were presumably incorporated into somewhat different lipid populations, all three were approximately equally effective in labeling the lipids transported ...

Abnormalities of the axonal cytoskeleton in giant axonal neuropathy

Journal of Neurocytology, 1988
Intermediate filaments accumulate abnormally in a variety of cell types in individuals with human inherited giant axonal neuropathy (GAN). A characteristic feature of this disorder is the occurrence of focal axonal enlargements filled with accumulations of neurofilaments.

Persistence of Axonal Transport in Isolated Axons of the Mouse

European Journal of Neuroscience, 1993
AbstractWe have examined the hypothesis, for the case of mouse axons, that isolating an axon from its cell body will lead to a rapid failure of fast axonal transport as anterogradely moving organelles vacate the axon in a proximo‐distal direction, and retrogradely moving organelles vacate it in the opposite direction.

Axon Resealing Following Transection Takes Longer in Central Axons Than in Peripheral Axons: Implications for Axonal Regeneration

Experimental Neurology, 2001
Injury to axons in the CNS leads to little regenerative repair and loss of function. Conversely, injury to axons in the PNS results in vigorous regrowth of severed axons, usually with restoration of function. This difference is generally attributed to a CNS environment that either cannot support or actively inhibits regeneration and/or a failure of CNS

AXONAL REGENERATION

Biological Reviews, 1996
Axons damaged in a peripheral nerve are often able to regenerate from the site of injury along the degenerate distal segment of the nerve to reform functional synapses. Schwann cells play a central role in this process. However, in the adult mammalian central nervous system, from which Schwann cells are absent, axonal regeneration does not progress to ...
