RATIONALE Individuals vary in their susceptibility to nicotine addiction. However, there is little evidence that behavioral sensitivity to nicotine is dependent upon the functional state of nicotinic cholinergic receptors (nAChRs). OBJECTIVE This study aims to determine the relationship between in vivo behavioral desensitization and in vitro(More)
cell carcinoma of the head and neck (SCCHN) is the sixth commonest human malignancy with an estimate of nearly 900 000 new cases occurring worldwide in 1995 (Parkin et al, 1993). In this review, head and neck cancer is defined as squamous cell carcinoma occurring in the upper aerodigestive tract, superior to the clavicles, excluding skin cancer and(More)
BACKGROUND Squamous cell carcinoma (SCC) of the tonsil is the most common malignant tumour of the oropharynx. Paediatric tonsillectomy is one of the most commonly performed procedures in Otorhinolaryngology. SCC of the tonsil remnant (SCCTR) in a previously tonsillectomised patient is rare. METHODS Retrospective review of patients with SCCTR presenting to(More)
The Lewis (LEW) strain of rat appears more sensitive to nicotine than other strains in self-administration, conditioned place preference, and drug discrimination behavioral studies. The present study sought to further evaluate the behavioral effects of chronic nicotine treatment in the LEW strain by assessing spontaneous activity, which has consistently(More)
This study, conducted in 36 human volunteers, was an evaluation of the effects of saline iontophoresis on skin temperature, irritation, and barrier function. The major objectives were to assess the effects of low-level ionic currents, to validate the proposed methodology of assessment, and to establish reproducibility in repeated saline iontophoresis(More)
Glia maturation factor (GMF) was tested on separate cultures of glioblasts and fibroblasts isolated from the same rate fetuses. The astrocytic marker glial fibrillary acidic (GFA) protein and the fibroblast marker fibronectin were visualized with immunofluorescence. Before GMF stimulation, glioblasts showed only background fluorescence for GFA protein and(More)
