Depletion of putative chemosensitive respiratory neurons in the ventral medullary surface in multiple system atrophy.
Multiple system atrophy (MSA) is a disorder that may manifest with reduced respiratory chemosensitivity and central sleep apnoea. Chemosensitive glutamatergic and serotonergic neurons located just beneath the ventral medullary surface, corresponding to the human arcuate nucleus (ArcN), have recently been implicated in control of automatic breathing in response to hypercapnia and hypoxia. We sou...
متن کاملTitle Chemosensitive running droplet
Chemical control of the spontaneous motion of a reactive oil droplet moving on a glass substrate under an aqueous phase is reported. Experimental results show that the self-motion of an oil droplet is confined on an acid-treated glass surface. The transient behavior of oil-droplet motion is also observed with a high-speed video camera. A mathematical model that incorporates the effect of the gl...
متن کاملSolubilization of adrenal medullary opioid receptors.
The opioid-binding activity of digitonin extract of bovine adrenal medullary membranes was studied. [3H]Diprenorphine binding to the solubilized material was rapid and saturable. The dissociation constant of [3H]diprenorphine binding was 0.76 nM. Several opioids displaced the [3H]diprenorphine binding. The complex of [3H]diprenorphine and the solubilized binding sites was eluted as a single pea...

متن کاملCattaneo models for chemosensitive movement
We derive models for chemosensitive movement based on Cattaneo’s law of heat propagation with finite speed. We apply the model to pattern formation as observed in experiments with Dictyostelium discoideum, with Salmonella typhimurium and with Escherichia coli. For Salmonella typhimurium we make predictions on pattern formation which can be tested in experiments. We discuss the relations of the ...
