Neuronal nicotinic acetylcholine receptors (nAChRs) are ligand-gated ion channels that are
widely distributed both pre-and post-synaptically in the mammalian brain. By modulating …

Three radioligands have been commonly used to label putative nicotinic cholinoceptors in
the mammalian central nervous system: the agonists [3H] nicotine and [3H] acetylcholine …

Until recently, research on (S)-(-)-nicotine (1, hereafter simply nicotine) and nicotinic
acetylcholine receptors (nAChRs) emphasized two principal aspects. The first was the …

Tritiated acetylcholine was used to measure binding sites with characteristics of nicotinic
cholinergic receptors in rat brain. Regulation of the binding sites in vivo was examined by …

Nicotine is a very widely used drug of abuse, which exerts a number of neurovegetative,
behavioural and psychological effects by interacting with neuronal nicotinic acetylcholine …

In Alzheimer's disease (AD), there is a loss of presynaptic cholinergic markers in the
cerebral cortex, but the nature of cholinergic receptor changes is unclear. In this study,[3 …

This review summarizes studies that attempted to determine the subtypes of nicotinic
acetylcholine receptors (nAChR) expressed in the dopaminergic nerve terminals in the …

Natural products that have both plant growth regulatory properties and pharmaceutical
properties are examined in this book. This is the first and most up-to-date text linking …

Many smokers, ex-smokers, and scientists have strong opinions about the effects of
abstinence from tobacco. Some believe the effects are mild, are not true withdrawal …
