DESCRIPTION (provided by applicant): The overall goal of this Mentored Research Scientist Award (K01) application is to explore the behavioral and pharmacological ramifications of concurrent ethanol and nicotine administration while providing the candidate (Dr. Matthew Ford) with an enriched training environment and a diversified research experience that will serve to nurture his transition to an independent investigator. The candidate will complement already familiar and established self-administration procedures by working closely with the mentor/sponsor (Dr. Kathleen Grant) to establish proficiency in training drug discriminations for single drugs and drug mixtures. In addition to learning the theory behind the drug discrimination procedure, the concepts of associative blocking and overshadowing will be directly studied in relation to ethanol and nicotine interactions in the generation of a conditioned drug cue. The candidate will also become familiar with several pharmacological strategies that are commonly employed to evaluate the salience and characteristics of a discriminative drug cue, such as, generalization testing and dose-response curve assessments. The sponsor will also guide the candidate in the practice of data analysis, data interpretation and the identification of procedural limitations as specifically related to the drug discrimination procedure. The proposed studies will test specific aims that address the influence of nicotine exposure history and dose on ethanol selfadministration outcomes and evaluate the impact of nicotine on the stimulus control exhibited by an interceptive ethanol cue. This mentored training opportunity will permit the candidate to accumulate additional research skills and experience in neuropharmacological and behavioral approaches to studying alcohol and other abused drugs, and will cement a solid foundation on which to stand as an independent principal investigator. Relevance: An estimated 90% of alcoholics engage in smoking behavior. Through the investigation of concurrent nicotine and ethanol administration, this research application seeks to arrive at a more complete understanding of the functional interactions between nicotine and ethanol. This investigational approach will provide valuable insights into the prevalence of their co-abuse liability, with the added potential to identify treatment strategies for ethanol and nicotine co-dependence.

描述（由申请人提供）：本指导研究科学家奖（K01）申请的总体目标是探索同时施用乙醇和尼古丁的行为和药理学影响，同时为候选人（马修·福特博士）提供丰富的培训环境和多元化的研究经验将有助于培养他向独立研究者的转变。候选人将通过与导师/赞助者（凯瑟琳格兰特博士）密切合作来补充已经熟悉和建立的自我管理程序，以建立对单一药物和药物混合物的药物歧视培训的熟练程度。除了学习药物辨别程序背后的理论之外，还将直接研究与乙醇和尼古丁相互作用在条件药物提示生成过程中相关的联想阻断和遮蔽概念。考生还将熟悉几种常用于评估区别性药物线索的显着性和特征的药理学策略，例如泛化测试和剂量反应曲线评估。申办者还将指导候选人进行数据分析、数据解释和识别与药物歧视程序特别相关的程序限制。拟议的研究将测试具体目标，以解决尼古丁暴露史和剂量对乙醇自我给药结果的影响，并评估尼古丁对拦截性乙醇提示所表现出的刺激控制的影响。这种指导培训机会将使候选人能够在研究酒精和其他滥用药物的神经药理学和行为方法方面积累额外的研究技能和经验，并将为作为独立首席研究员奠定坚实的基础。相关性：估计 90% 的酗酒者有吸烟行为。通过对尼古丁和乙醇同时给药的研究，本研究应用旨在更全面地了解尼古丁和乙醇之间的功能相互作用。这种研究方法将为了解其共同滥用倾向的普遍程度提供有价值的见解，并有可能确定乙醇和尼古丁相互依赖的治疗策略。
