A reflection on the essence of gratitude in palliative care: healing in severe disease and professional affirmation through accompanying patients until the end.

Background: Gratitude has sparked interest in the world of health. It is considered as a personality characteristic or as an emotion. However, little has been explored in the context of the interpersonal relationship of caring.

Diapause induces functional axonal regeneration after necrotic insult in C. elegans.

Many neurons are unable to regenerate after damage. The ability to regenerate after an insult depends on life stage, neuronal subtype, intrinsic and extrinsic factors. C.

The Molecular Interplay between Axon Degeneration and Regeneration.

Neurons face a series of morphological and molecular changes following trauma and in the progression of neurodegenerative disease. In neurons capable of mounting a spontaneous regenerative response, including invertebrate neurons and mammalian neurons of the peripheral nervous system (PNS), axons regenerate from the proximal side of the injury and degenerate on the distal side. Studies of Wallerian degeneration slow (Wld /Ola) mice have revealed that a level of coordination between the processes of axon regeneration and degeneration occurs during successful repair.
