L-Nicotine is classified as super toxic. Probable oral lethal dose in humans is less than 5 mg/kg or a taste (less than 7 drops) for a 70 kg (150 lbs.) person. It may be assumed that ingestion of 40-60 mg of nicotine is lethal to humans. There is fundamental difference between ...
Scores from 0.3 to 1.0 were classified as sign trackers, while scores from − 0.3 to − 1.0 were classified as goal trackers, and scores from − 0.3 to 0.3 were classified as intermediate. BDNF protein as detected by Western blots was normalized to the GAPDH loading control. To ...
nAchR's may be classified either as homopentameric, which consist of five identical subunits, or heteropentameric, which consist of at least one α subunit and one β subunit. The principal homomeric nAchR form is the α7 subtype, and the principal heteromeric form is the α4β2 subtype. ...
With an estimated one billion individuals worldwide classified as tobacco users—and tobacco use often being synonymous with nicotine addiction—nicotine is one of the world’s most common addictive substances, and a frequent comorbidity of misuse of other common addictive substances.

(±)-Nicotine focus on elucidating the role of these receptors in cognitive processes such as memory and attention. In addition, this compound is used in investigations into the molecular basis of addiction, where it serves as a tool to understand the neurological pathways and receptor mechanisms ...
Frequency of product use was classified based on self-reported every-day use or some-days use of cigarettes and/or e-cigarettes. Exploratory analyses were conducted among dual users to examine whether frequency of dual use was associated with concentration of nicotine and toxicants. A description ...
Although Park et al11 and Westling et al12 showed that adolescents can be classified into distinct trajectories of vaping, neither study examined the transition from adolescence to young adulthood. This is a population at high risk because transitions to college and/or the workforce and increased ...
