Axon, 2023 Come le altre, anche la ϝράτρα per gli Elei è un oracolo di Zeus Olimpio; in questo caso, il dio ordina di trattare lo straniero – e segretario – Patrias come fosse un eleo, quando sia vittima di una maledizione.

Intra-axonal mechanisms driving axon regeneration
Brain Research, 2020 Traumatic injury to the peripheral and central nervous systems very often causes axotomy, where an axon loses connections with its target resulting in loss of function. The axon segments distal to the injury site lose connection with the cell body and degenerate.

Flamingo Regulates R8 Axon-Axon and Axon-Target Interactions in the Drosophila Visual System [PDF]
Current Biology, 2003 Photoreceptors (R cells) in the Drosophila retina connect to targets in three distinct layers of the optic lobe of the brain: R1-R6 connect to the lamina, and R7 and R8 connect to distinct layers in the medulla. In each of these layers, R axon termini are arranged in evenly spaced topographic arrays. In a genetic screen for mutants with abnormal R cell

Molecular Oncology, EarlyView.Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

La tablette de bronze d’Idalion
Axon, 2021 Contrat conclu entre le roi et la cité d’Idalion, d’une part, et le médecin Onasilos et ses frères, de l’autre part, au sujet de la récompense de ceux-ci pour avoir soigné les blessés pendant le siège de la ville par les Mèdes et les Kitiens.

Neuronal Dynamics and Axonal Flow: Axonal Peristalsis [PDF]
Proceedings of the National Academy of Sciences, 1972 By time-lapse, phase-contrast cinemicrography of sensory nerve fibers of young mice, isolated with their originating spinal ganglia in nutrient solution, the postulated peristaltic surface drive of the cellulifugal propulsion of the semisolid axonal column at a rate of the order of 1 mm/day (1 μm/min) could be verified and quantitatively analyzed.

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells
FEBS Open Bio, EarlyView.Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

Microchannels as Axonal Amplifiers
IEEE Transactions on Biomedical Engineering, 2008 An implantable neural interface capable of reliable long-term high-resolution recording from peripheral nerves has yet to be developed. Device design is challenging because extracellular axonal signals are very small, decay rapidly with distance from the axon, and in myelinated fibres are concentrated close to nodes of Ranvier, which are around 1 mum ...
