• Nicotine tests can be conducted using both qualitative and quantitative means that detect nicotine, cotinine, and anabasine - a breakdown product of nicotine. (wotofo.com)
  • Previously, the identification of ancient plant residues relied on the detection of a limited number of biomarkers, such as nicotine, anabasine, cotinine and caffeine. (wsu.edu)
  • Specifically, biomarkers such as carbon monoxide, cotinine, and anabasine, measured at regular intervals, can provide clinicians with much clearer, clinically relevant and actionable assessments of current tobacco use by their patients. (biomedcentral.com)
  • The fibrillation of α-synuclein was studied in relation to five different compounds found in cigarette smoke: anabasine, cotinine, hydroquinone, nicotine and nornicotine. (usf.edu)
  • The presence of nicotine in biological specimens indicates exposure to tobacco, either through the active use of tobacco, or from passive exposure to secondhand smoke (SHS). (cdc.gov)
  • Lastly, anatabine and anabasine are nicotine analogs in tobacco product, and are precursors for nitrosamines. (cdc.gov)
  • Insurance firms treat nicotine presence as a reliable sign that the person is an active tobacco user if not an NRT (nicotine replacement therapy) product user that often implies an ex-smoker (and a person who is susceptible to returning to the smoking habit, as over 90% of NRT product users usually do).

  • Gang said the issue with this approach is while the presence of a biomarker like nicotine shows tobacco was smoked it doesn't distinguish which species it was. (wsu.edu)
  • The morphology of the oligomers stabilized by nicotine was evaluated by AFM, which showed the presence of three stable oligomers with an average height of 16 nm, 10 nm and 4 nm. (usf.edu)
  • In fresh N. tabacum , the alkaloid cortege typically consists of 93% S-nicotine 1 , 3.9% S-anatabine 2 , 2.4% S-nornicotine 3 , and 0.5% S-anabasine 4 [1]. (freemanvapejuice.com)
  • Analysis of a second pipe that was used by people living in Central Washington after Euro-American contact revealed the presence of a different tobacco species, N. rustica, which was grown by native peoples on the east coast of what is now the United States. (wsu.edu)
  • This's is often due to the presence of thiocyanate - a compound commonly found in foodstuffs such as cabbage and broccoli, and sometimes in various medications. (wotofo.com)
  • Cis-N-oxide, trans-N-oxide, myosmine, anatabine and anabasine were the most common additional compounds found. (nih.gov)
  • Lastly, anatabine and anabasine are nicotine analogs in tobacco product, and are precursors for nitrosamines. (cdc.gov)
  • Heavy tobacco users who abstain from tobacco for 2 weeks usually have urine nicotine values less than 30 ng/mL, cotinine less than 50 ng/mL, anabasine less than 2 ng/mL, and nornicotine less than 2 ng/mL. (clinlabnavigator.com)
  • Previously, the identification of ancient plant residues relied on the detection of a limited number of biomarkers, such as nicotine, anabasine, cotinine and caffeine. (wsu.edu)
  • We assessed nicotine content, content of the known nicotine degradation products and impurities, and presence of ethylene glycol and diethylene glycol. (nih.gov)
  • The presence of nicotine in biological specimens indicates exposure to tobacco, either through the active use of tobacco, or from passive exposure to secondhand smoke (SHS). (cdc.gov)
  • Two examples are anabasine and nornicotine, which are present in tobacco products, but not nicotine replacement therapies. (clinlabnavigator.com)
  • The presence of anabasine and nornicotine anabasine greater than 10 ng/mL or nornicotine greater than 30 ng/mL in urine indicates active use of a tobacco product, regardless of whether the individual is using nicotine replacement therapy. (clinlabnavigator.com)
  • The presence of nornicotine without anabasine is consistent with use of nicotine replacement products. (clinlabnavigator.com)
  • Gang said the issue with this approach is while the presence of a biomarker like nicotine shows tobacco was smoked it doesn't distinguish which species it was. (wsu.edu)
