Botulinum neurotoxin serotypes A and E (BoNT/A and BoNT/E) block neurotransmitter release, presumably by cleaving SNAP-25, a protein involved in docking of synaptic vesicles with the presynaptic plasma membrane. Three excitation-secretion uncoupling

Neuroprotective effects of HU-211 (dexanabinol), a synthetic nonpsychotropic analog of tetrahydrocannabinol, on brain damage resulting from soman-induced seizures were examined in male Sprague-Dawley rats challenged with 1.6 LD50 soman. At 5 or 40 mi

The binding activity of a rabbit polyclonal antiserum raised against a 51-residue peptide (P51) homologous to human VAMP2 (residues 44–94) was examined. Human VAMP2 is an 18-kDa protein located on the external membrane of small synaptic vesicles an

The effects on membrane fluidity of inhibitors of acetylcholinesterase (A ChE) as well as those of certain nicotinic agonists have been examined in synaptosomes prepared from the electroplax of Torpedo californica. Electron paramagnetic resonance (EP

We have assessed the efficacy of MAP-2 immunohistochemistry as a marker of seizure-related brain damage and its suitability for quantitation of the damage using densitometric and morphometric image analysis. Seizures were produced in rats by administ

An in vitro mammalian model neuronal system to evaluate the intrinsic toxicity of soman and other neurotoxicants as well as the efficacy of potential countermeasures was investigated. The link between soman toxicity, glutamate hyperactivity and neuro

The effect of intravenous mannitol on soman-induced neuropathology and cardio-myopathy was studied in rats. Soman, an organophosphorus agent, irreversibly inhibits total body acetylcholinesterase and induces a cholinototoxic syndrome in rats which re

The role of butyrylcholinesterase (BuChE) and acetylcholinesterase (AChE) in regulating acetylcholine (ACh) lifetime was investigated by use of selective cholinesterase (ChE) inhibitors. Addition of 1 μM tetraisopropylpyrophosphoramide (iso-OMPA) le

Soman-induced respiratory failure was investigated in awake, behaving guinea pigs chronically instrumented to allow concurrent recordings of medullary respiratory-related unit (RRU) activity, diaphragm electromyogram (DEMG), and electrocorticogram. R
