Regulation of Neuromodulator Receptor Efficacy - Implications for Whole-Neuron and Synaptic Plasticity [PDF]

, 2004
Membrane receptors for neuromodulators (NM) are highly regulated in their distribution and efficacy - a phenomenon which influences the individual cell's response to central signals of NM release.

A role for epithelium‐derived 6‐nitrodopamine on human ureter contractility

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose To investigate the basal release of 6‐nitrodopamine (6‐ND) from human isolated ureter and the role of this novel catecholamine in the ureter contractility. Experimental Approach Ureters from 67 brain‐dead organ donors (40 males and 27 females) were used during kidney transplantation procedures.

Respiratory dysfunction and fatal apnea during pilocarpine‐induced status epilepticus

Epilepsia, EarlyView.
Abstract Objective Status epilepticus (SE) is second only to sudden unexpected death in epilepsy as a cause of seizure‐related mortality. The progression of respiratory dysfunction during experimental SE remains poorly characterized. We investigated how pilocarpine‐induced SE affects respiration in mice.

Allosteric Modulation of Muscarinic Acetylcholine Receptors

Pharmaceuticals, 2010
An allosteric modulator is a ligand that binds to an allosteric site on the receptor and changes receptor conformation to produce increase (positive cooperativity) or decrease (negative cooperativity) in the binding or action of an orthosteric agonist (e.

Spreading depolarization and its influence on epileptiform activity

Epilepsia, EarlyView.
Abstract Spreading depolarization (SD) is a transient disruption of electrographic activity that slowly propagates through the gray matter by chemical contiguity, and it is characterized by a large depolarization of neurons and glial cells. SD, which is associated with massive changes in ion homeostasis, including extreme increases in [K+]o, was shown ...

Cardiac muscarinic receptor overexpression in sudden infant death syndrome.

PLoS ONE, 2010
BackgroundSudden infant death syndrome (SIDS) remains the leading cause of death among infants less than 1 year of age. Disturbed expression of some neurotransmitters and their receptors has been shown in the central nervous system of SIDS victims but no

Management of an uncommon complication using botulinum toxin type A following prosthetic laryngoplasty

Equine Veterinary Education, EarlyView.
Summary An uncommon complication following prosthetic laryngoplasty was reported in a 4‐year‐old Andalusian mare. The mare was presented with a previously diagnosed left‐sided recurrent laryngeal neuropathy, after initial evaluation the mare underwent ventriculocordectomy and prosthetic laryngoplasty.

Arctic lake trout (Salvelinus namaycush) show evidence of seasonal acclimation of cardiac adrenergic sensitivity but not heat tolerance

Journal of Fish Biology, EarlyView.
Abstract Many Arctic fishes experience prolonged periods of extreme cold and large thermal variation over both rapid and seasonal time scales which challenge critical physiological functions. In the central Canadian Arctic, we caught wild adult lake trout (Salvelinus namaycush) acclimatized to winter and summer temperatures to determine the extent to ...
