3. Nicotine as a Catalyst for Chlorination Promoted by Hypochlorous Acid: Experimental and Theoretical Studies
There is robust evidence of the hypochlorous acid (HClO)-mediated damage in biomolecules, and nicotine boosts the chlorination potency of HClO. We present experimental and theoretical evidence of the mechanism by which nicotine catalyzes the chlorination of pyranine. The rate constants for chlorination of pyranine by HClO were measured in the presence (5.3 �

4. Thrombotic thrombocytopenic purpura presenting as recurrent thrombocytopenia in a young female — A case report
Objective: This randomized controlled trial examined the efficacy and safety of N-acetylcysteine as an adjunctive treatment for smoking cessation. Methods: Heavy smokers were recruited from smoking cessation treatment for this 12- week randomized controlled trial. Eligible tobacco use disorder outpatients (n=34) were randomized to N-acetylcysteine or place

6. In-Vitro Model of Scardovia wiggsiae Biofilm Formation and Effect of Nicotine
Resumo Recentemente, foi relatado que Scardovia wiggsiae está fortemente associado à formação de cáries. Este estudo teve como objetivo estabelecer um modelo in vitro de biofilme de S. wiggsiae e investigar o efeito da nicotina no crescimento de unidades formadoras de colônias (UFC) de S. wiggsiae. O biofilme de S. wiggsiae foi cultivado durante a noit

8. Ameliorative Effects of Thymoquinone on Sperm Parameters and Testosterone Level of Nicotine-Treated Sprague Dawley Rats
Abstract Thymoquinone (TQ), the main constituent of the volatile oil derived from Nigella sativa has shown pharmacological benefits against various diseases while nicotine is an active component in cigarette that is known to be detrimental. This study was conducted to assess the ameliorating effects of TQ on sperm count, membrane, mitochondria and testostero

9. Use of derived adipose stem cells to reduce complications of cutaneous scarring in smokers. An experimental model in rats
Abstract Purpose To evaluate the use of adipose-derived stem cells (ADSC) in reducing the necrosis area in an experimental model of cutaneous ischemic flap in rats submitted to subcutaneous nicotine injection to simulate a smoker patient. Methods In an experimental study, 30 rats were enrolled and divided into two experimental groups of 15 animals all su

10. Experimentation with tobacco during adolescence as a factor influencing treatment of smoking in adulthood. A retrospective cohort
ABSTRACT BACKGROUND: There are still few studies on predictors of smoking cessation in Brazilian samples. Experimentation with tobacco during adolescence (ETA) may be one of the important predictors. OBJECTIVE: This study aimed, within the context of a treatment-seeking group of subjects, to test the hypothesis that ETA negatively affects the outcome of

11. Laser Photobiomodulation in the acute inflammatory response of the calcaneal tendon injury in rats exposed to cigarette smoke
RESUMO A nicotina retarda o processo de cicatrização e eleva os níveis da enzima mieloperoxidase (MPO), a qual possui um papel fundamental na produção de espécies reativas de oxigênio durante o processo inflamatório. A fotobiomodulação laser (FBM) é um dos agentes eletrofísicos mais utilizados no tratamento do tendão calcâneo, no entanto, os se

12. Effect of MDR C3435T polymorphism on Varenicline treatment in quit smoking
Despite so many global efforts, smoking still remains to be one of the most common addictions worldwide. Even though most smokers wish to quit smoking, many of them fail. In this respect, genetic variants are thought to be remarkable factors in nicotine dependence and in treatment of smoking cessation. This is a paper investigating a single variant p-glycopr
