A new look at the architecture and dynamics of the Hydra nerve net. [PDF]
Elife, 2023 Abstract The Hydra nervous system is the paradigm of a “simple nerve net”. Nerve cells in Hydra, as in many cnidarian polyps, are organized in a nerve net extending throughout the body column. This nerve net is required for control of spontaneous behavior: elimination of nerve cells leads to polyps that do not move and are incapable of ...

The Nerve Net of the Actinozoa [PDF]
Journal of Experimental Biology, 1935 ABSTRACTStimulation of the column of the anemone Calliatis parasitica elicits a graded series of responses. Each response is primarily due to the action of a single set of muscles. The means by which this effect is produced is physiologically simple.

Hydra: Imaging Nerve Nets in Action [PDF]
Current Biology, 2017 Mapping whole-brain activity during behavior represents one of the biggest and most exciting challenges of systems neuroscience. New research has taken advantage of the unique biology of an ancient organism to bring us a step closer to that goal.

Journal of the American Medical Association, 1920 From biologic studies it must be inferred that the sole reason for life—vegetable, animal and human— is to continue the species, and that man's superior brain and body are for the purpose of better protecting the germ plasm as well as for social life, the pleasure of work and the joy of mental effort. We worship the mind and its products, and outwardly

Maintenance and Regeneration of the Nerve Net in Hydra [PDF]
American Zoologist, 1988 Description des proprietes et de la dynamique du reseau nerveux. On observe comment ces proprietes sont impliquees dans la maintenance du reseau nerveux dans le contexte de la dynamique du tissu chez l'adulte ainsi que pendant le developpement du reseau nerveux au moment de la regeneration de la ...

Cnidarian Nerve Nets and Neuromuscular Efficiency [PDF]
Integrative and Comparative Biology, 2015 Cnidarians are considered "nerve net animals" even though their nervous systems include various forms of condensation and centralization. Yet, their broad, two-dimensional muscle sheets are innervated by diffuse nerve nets. Do the motor nerve nets represent a primitive organization of multicellular nervous systems, do they represent a consequence of ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
