Transcriptome analysis of nicotine-exposed cells from the brainstem of neonate spontaneously hypertensive and Wistar Kyoto rats
(NATURE PUBLISHING GROUP, 2010)
In this study, the effects of nicotine on global gene expression of cultured cells from the brainstem of spontaneously hypertensive rat (SHR) and normotensive Wistar Kyoto (WKY) rats were evaluated using whole-genome ...
The role of nicotine, cotinine and caffeine on the electrochemical behavior and bacterial colonization to cp-Ti
(Elsevier B. V., 2015-11-01)
Although smoking promotes deleterious effect to bone healing, there is a lack of study investigating its role on the implant structure and biofilm growth. We hypothesized that nicotine, cotinine and caffeine would impair ...
The reward-attention circuit model: nicotine's influence on attentional focus and consequences on attention deficit hyperactivity disorder
(Elsevier Science Bv, 2017-06-14)
In this work we investigate the influence that nicotine exerts on attention focusing, modeling the coupling of reward and thalamocortical circuits. Each neuron in the neural networks that replicate such circuits is described ...
Exposure to acute restraint stress reinstates nicotine-induced place preference in rats
(Lippincott Williams & Wilkins, 2009-02-01)
Tobacco addiction is associated with high rates of relapse to drug use even after prolonged periods of abstinence. Relapse can occur upon reexposure to the drug of abuse, exposure to stress or to stimuli associated with ...
Antimicrobial photodynamic therapy minimizes the deleterious effect of nicotine in female rats with induced periodontitis
The aim of this study was to compare the use of antimicrobial photodynamic therapy (aPDT) as an adjunct to scaling and root planing (SRP) in the treatment of experimentally induced periodontitis in female rats that were ...
α7-type acetylcholine receptor localization and its modulation by nicotine and cholesterol in vascular endothelial cells
The neuronal-type 7 nicotinic acetylcholine receptor (7AChR) is also found in various non-neural tissues, including vascular endothelium, where its peculiar ionotropic properties (high Ca2+ permeability) and its supervening ...
Action of nicotine and ovariectomy on bone regeneration after tooth extraction in rats
(W B Saunders Co-elsevier Inc, 2010-11-01)
Purpose: The purpose of this study was to evaluate the effects of nicotine and ovariectomy on alveolar bone regeneration after exodontias in rats.Materials and Methods: For 30 days, sham ovariectomized (OVX)/NaCl, sham ...
Baclofen and 2-hydroxysaclofen modify acute hypolocomotive and antinociceptive effects of nicotine
(Elsevier Science, 2014-09)
The aim of the present study was to evaluate the possible involvement of GABAB receptors in nicotine-induced hypolocomotion and antinociceptive effects in mice. Animals were exposed to nicotine only once. Acute nicotine ...
Stress induces behavioral sensitization, increases nicotine-seeking behavior and leads to a decrease of CREB in the nucleus accumbens
(Pergamon-Elsevier B.V. Ltd, 2014)
Influence of nicotine on healing process of autogenous bone block grafts in the mandible: A histomorphometric study in rats
(QUINTESSENCE PUBLISHING CO INC, 2008)
Purpose: The aim of this study was to perform qualitative and quantitative analyses of the effect of nicotine on autogenous bone block grafts and to describe events in the initial healing phase and the differences in the ...
