1. Influence of cigarette smoke combined with different toothpastes on enamel erosion
Abstract: This in vitro study aimed to evaluate the effect of different toothpastes on dental enamel subjected to an erosive cycle with and without exposure to cigarette smoke. Bovine enamel specimens were randomly allocated into 12 groups (n = 12). For the in vitro simulation of smoking, half the groups underwent an exposure cycle of 20 cigarettes per day f

2. DNA Damage by Endogenous and Exogenous Aldehydes
The present overview describes the formation of deoxyribonucleic acid (DNA) adducts from endogenous and exogenous aldehydes, such as acetaldehyde, acrolein, crotonaldehyde, malonaldehyde, 4-hydroxy-2-nonenal and 2,4-decadienal. Malonaldehyde reacts with 2’-deoxyguanosine, 2’-deoxyadenosine, and 2’-deoxycytidine, yielding cyclic pyrimidopurinone and acy

3. 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

4. Biomass smoke COPD has less tomographic abnormalities but worse hypoxemia compared with tobacco COPD
Special attention has emerged towards biomass smoke-induced chronic obstructive pulmonary disease (COPD), providing new knowledge for prevention and therapeutic approach of non-smoker COPD patients. However, the understanding of biomass smoke COPD is still limited and somewhat controversial. The aim of the present study was to compare COPD exclusively caused

5. Mineral composition, histomorphometry, and bone biomechanical properties are improved with probiotic, prebiotic, and symbiotic supplementation in rats chronically exposed to passive smoking: a randomized pre-clinical study
RESUMO: A fumaça de cigarro em grandes centros é uma das causas mais importantes de doenças inflamatórias crônicas em saúde pública e esta associada à diminuição de massa óssea, processo de consolidação e remodelação óssea. Os alimentos funcionais suplementados na dieta, devido sua capacidade de melhorar a absorção intestinal e competir co

6. Neonatal tobacco smoke reduces thermogenesis capacity in brown adipose tissue in adult rats
Maternal smoking is a risk factor for progeny obesity. We have previously shown, in a rat model of neonatal tobacco smoke exposure, a mild increase in food intake and a considerable increase in visceral adiposity in the adult offspring. Males also had secondary hyperthyroidism, while females had only higher T4. Since brown adipose tissue (BAT) hypofunction i

8. The effects of passive tobacco smoking on the microcirculation of the abdominal wall in rats
ABSTRACT PURPOSE: To analysis the effects of passive smoking on the microstructure of tissues of the abdominal wall regarding microcirculation, using histopathological study of the tobacco exposed rats. METHODS: Twenty four male Wistar rats were divided in Control Group (CG = 8 animals) and Exposition Groups (EG = 16 animals). EG was exposed to cigarette

9. Oxidative stress and skeletal muscle dysfunction are present in healthy smokers
Chronic exposure to cigarette smoke seems to be related to an increase of pro-inflammatory cytokines, oxidative stress and changes in muscular and physical performances of healthy smokers. However, these parameters have not yet been evaluated simultaneously in previous studies. The participants of this study were healthy males divided into two groups: smoker

11. Short term exposure to cigarette smoke on general activity and anxiety
RESUMO OBJETIVO: Exposição à fumaça de cigarro em "sidestream" difere da exposição ativa, pois apresenta efeitos mais intensos. Nosso objetivo foi avaliar o desempenho de ratos expostos à fumaça do cigarro em "sidestream", a curto prazo, em testes em campo aberto e em labirinto elevado em cruz. MÉTODO: A exposição do cigarro foi realizada durant

12. Parental smoking patterns and their association with wheezing in children
OBJECTIVE: To investigate parental smoking patterns and their association with wheezing in children. METHODS: We performed a case-control study that included 105 children between 6 and 23 months of age who were divided into two groups: cases (children with 3 previous episodes of wheezing) and controls (healthy children without wheezing). The children's expo
