Alginate/chitosan hydrogel containing olfactory ectomesenchymal stem cells for sciatic nerve tissue engineering

Journal of Cellular Physiology, 2019
Regeneration and functional recovery after peripheral nerve damage still remain a significant clinical problem. In this study, alginate/chitosan (alg/chit) hydrogel was used for the transplantation of olfactory ectomesenchymal stem cells (OE‐MSCs) to ...

Olfactory ensheathing cells and olfactory nerve fibroblasts maintain continuous open channels for regrowth of olfactory nerve fibres

Glia, 2005
AbstractThe ensheathing cells of the olfactory nerves are arranged end‐to‐end to form a continuous channel enclosing the olfactory axons from their origin in the olfactory mucosa to their termination in the olfactory bulb. On their outer surface, the olfactory ensheathing cell channels have a basal lamina and an outer encirclement of olfactory nerve ...

Olfactory Nerve (Cranial Nerve I)

2003
All animals from simple single cell organisms through to complex vertebrates detect and react to chemicals/odors in their external environment, some at concentrations of only a few parts per million. These environmental odors are generally complex mixtures of individual chemicals/odorants; coffee, for example, may contain as many as 1000 separate ...

Neuroblastoma of the olfactory nerve

Acta Neurochirurgica, 1971
Two cases of an olfactory neuroblastoma are reported. The leading symptom was the increase in intracranial pressure. In spite of radical exstirpation—removal of the intracranial part including the infiltrated brain tissue as well as the part extending into the paranasal sinuses via a bifrontal transcranial approach—and postoperative radiation the ...

Slow transport in a nerve with embryonic characteristics, the olfactory nerve

Developmental Brain Research, 1988
The kinetics for slowly transported polypeptides have been examined in intact garfish olfactory nerves. The shape of the slow peak is essentially determined by alpha-and beta-tubulin which are by far the major polypeptides of the entire wave. The proximal area of the peak is similar to the slow component a (Sca) subcomponent defined in other nerves and

Olfactory nerves and their excitatory action in the olfactory bulb

Experimental Brain Research, 1972
Extracellular field potentials were recorded from the rabbit olfactory bulb following stimulation of the surface and the lateral olfactory tract. Experiments were also performed on olfactory nerve rootlets and a conduction velocity of .34 m/sec and an absolute refractory period of 2.7 msec were obtained.

Ensheathment of the olfactory nerves in the adult rat

Journal of Neurocytology, 2003
The ensheathment of the olfactory nerve fibres is achieved by cooperation of two cell types. The olfactory ensheathing cells have a rounded outer surface enclosed in a continuous single basal lamina, and enclose an inner compartment from which overlapping processes of the same and adjacent cells enwrap interweaving territories of tightly apposed ...

Dopaminergic modulation at the olfactory nerve synapse

Brain Research, 2000
Dopamine can change the membrane potential, regulate cyclic nucleotides, and modulate transmitter release in central neurons. In the olfactory bulb (OB), the dopamine synthetic enzyme, tyrosine hydroxylase, is largely confined to neurons in the glomerular layer. After demonstrating dopamine D2 receptors in the glomerular and olfactory nerve (ON) layers,

The spatial organization of olfactory nerve projections

Brain Research, 1987
The spatial organization of olfactory nerve projections was examined in the rat. The pathway was traced by orthograde transport of HRP following nasal lavage and by retrograde transport of HRP following injections into the olfactory bulb. The results indicated that there was a broad relationship between the epithelium and the olfactory bulb.

Survey on Olfactory Testing by Pediatric Neurologists: Is the Olfactory a “True” Cranial Nerve?

Journal of Child Neurology, 2020
Background: The olfactory nerve was conceptualized in the 4th century BC by Alcmaeon and described anatomically by Winslow in 1733. Cranial nerves (CNs) were named and numbered by Soemmerring in 1791. Notions still prevail that the olfactory (CN1) is not a “true” cranial nerve. Methods: To confirm our impression that the olfactory nerve is infrequently
