Neurobiology of nicotine dependence
Nicotine is a psychoactive ingredient in tobacco that significantly contributes to the harmful tobacco smoking habit. Nicotine dependence is more prevalent than dependence on any other substance. Preclinical research in animal models of the various aspects of nicotine dependence suggests a critical role of glutamate, g-aminobutyric acid (GABA), cholinergic and dopamine neurotransmitter interact...
متن کاملSusceptibility to nicotine dependence: the Development and Assessment of Nicotine Dependence in Youth 2 study.
OBJECTIVES The purpose of this work was to identify characteristics that predict progression from the first inhalation of a cigarette to dependence. We studied a cohort of 1246 public school 6th-graders in 6 Massachusetts communities (mean age at baseline: 12.2 years). METHODS We conducted a 4-year prospective study using 11 interviews. We assessed 45 risk factors and measured diminished auto...
متن کاملBehavioral responses to surveys about nicotine dependence.
Behavioral responses to surveys can significantly affect inferences about population prevalence unless correctly modeled statistically. An important case study is the prevalence of nicotine dependence, a formal psychiatric disorder satisfying clinical criteria. Data from the National Epidemiologic Survey on Alcohol and Related Conditions in the United States are used, along with a flexible semi...
متن کاملPerinatal nicotine exposure induces asthma in second generation offspring
BACKGROUND By altering specific developmental signaling pathways that are necessary for fetal lung development, perinatal nicotine exposure affects lung growth and differentiation, resulting in the offsprings' predisposition to childhood asthma; peroxisome proliferator-activated receptor gamma (PPARγ) agonists can inhibit this effect. However, whether the perinatal nicotine-induced asthma risk ...
متن کاملBrain uptake kinetics of nicotine and cotinine after chronic nicotine exposure.
Blood-brain barrier (BBB) nicotine transfer has been well documented in view of the fact that this alkaloid is a cerebral blood flow marker. However, limited data are available that describe BBB penetration of the major tobacco alkaloids after chronic nicotine exposure. This question needs to be addressed, given long-term nicotine exposure alters both BBB function and morphology. In contrast to...
