6. Different levels of brain-derived neurotrophic factor and cortisol in healthy heavy smokers
Studies suggest that brain-derived neurotrophic factor (BDNF) and the hypothalamic-pituitary-adrenal (HPA) axis modulate dopaminergic activity in response to nicotine and that the concentrations of BDNF and cortisol seem to be dependent on the amount and duration of smoking. Therefore, we investigated BDNF and cortisol levels in smokers ranked by daily cigar

10. Single gas chromatography method with nitrogen phosphorus detector for urinary cotinine determination in passive and active smokers
A nicotina é uma substância presente no cigarro capaz de causar dependência, sendo biotransformada em vários metabólitos nos seres humanos, dentre eles a cotinina urinária, que é considerada um indicador biológico de exposição à nicotina, devido a suas altas concentrações, comparado a outras matrizes. Assim, o objetivo deste estudo foi desenvolv

12. Avaliação in vitro dos efeitos da nicotina e cotinina sobre a expressão de proteinas e capacidade de adesão e invasão de Porphyromonas gingivalis / In vitro evaluation of nicotine and cotinine effects on protein expression and adhesion and invasion abilities of Porphyromonas gingivalis
Cigarette smoking is associated with the development of periodontitis and the decreased response to periodontal therapy. P. gingivalis is an important colonizer of the subgingival biofilm and is one of the major pathogens involved in the initiation and progression of periodontal disease. However, the possible effects of major cigarette s derivatives on P. gi
