Neuronal nicotinic acetylcholine receptors (nAChRs) are a family of ligand-gated ion channels present in the central and peripheral nervous systems, that are permeable to mono- and divalent cations. They share a common basic structure but their pharmacological and functional properties arise from the wide range of different subunit combinations making up(More)
It has been suggested that nutritional manipulations during the first weeks of life can alter the development of the hypothalamic circuits involved in energy homeostasis. We studied the expression of a large number of the hypothalamic neuropeptide mRNAs that control body weight in mice that were overfed during breastfeeding (mice grown in a small litter,(More)

We have found that mice fed a high fat diet do not show the anorectic effect of chronic nicotine treatment, but do increase their body weight following nicotine withdrawal. Nicotine withdrawal is(More)
PURPOSE To examine the characteristics of effective preceptors, using the perceptions of students who are enrolled in a Dietetic Internship (DI), and to evaluate the influence of the following factors on preceptor behavior: a preceptors' area of practice, credentials, and type of DI program where the student is enrolled. METHODS Three hundred fifty-one(More)
