OBJECTIVE To determine associations between younger youths' susceptibility to smoking and four household variables related to tobacco socialization: parental and sibling smoking, restrictions on smoking in the home and exposure to smoking in vehicles. METHODS A secondary analysis of the 2004/05 Canadian Youth Smoking Survey used logistic regression to investigate the relationships between you...

PURPOSE Cigarette smoking has been associated with increased occurrence of multiple sclerosis (MS), as well as clinical disability and disease progression in MS. We aimed to assess the effects of smoking on the white matter (WM) in patients with clinically isolated syndrome (CIS) using diffusion tensor imaging. METHODS Smoker patients with CIS (n=16), smoker healthy controls (n=13), nonsmoker...

OBJECTIVE Maternal cigarette smoking is reportedly associated with miscarriage, fetal growth restriction and placental abruption, and is paradoxically associated with a decreased risk of developing preeclampsia. In the present study, we investigated the gene expression levels of villous tissues in early gestation. We compared the expression levels of the genes related to angiogenesis and apopto...

Chronic obstructive pulmonary disease (COPD) is a disease which genetic and environmental factors play an important role in COPD development. VDBP (Vitamin D Binding Protein ) gene might be responsible for COPD development. The purpose of this study to investigate the possible effect of VDBP on development of COPD. We studied VDBP genotypes in 75 COPD patients, 36 smoker healthy subjects and 19...

BACKGROUND Cigarette smoking is reported to decrease survival and induce chemotherapy resistance in patients with various cancers. However, the impact of cigarette smoking on patients with esophageal squamous cell carcinoma (ESCC) remains unknown. METHODS A total of 1,084 ESCC patients were retrospectively enrolled from a southern Chinese institution. Patients were divided into two groups acc...

various substances in cigarette smoke including nicotine have been shown to promote/induce cancer cell proliferation. since cotinine has a longer half life and stability in the blood, it has become the preferred biomarker for cigarette smoking exposure. seventy-three gastric cancer patients were included in this study. the tumor tissues were stained with h and e for pathological evaluation. the...

This study proposes a calibration method and analyses the effect of this in lung measures, using minimally invasive electrical impedance spectroscopy with 3-electrode method, for tissue differentiation between healthy neoplasm tissue. Tissue measurements were performed 99 patients [54 15 neoplastic samples obtained] an indicated bronchoscopy. Statistically significant difference (P < 0.001) fou...

BACKGROUND Since 2000 various tobacco control measures have been implemented in the UK. Changes in the smoking status of low and high socioeconomic status (SES) groups in England during this period (2001-08) are explored. METHODS Secondary analysis of the Health Survey for England general population samples was undertaken. Over 88 000 adults, age 16 or over, living in England were included. S...

Despite the detrimental impact of smoking on health, its prevalence remains high. Empirical research has provided insight into the many causes and effects of smoking, yet lay perceptions of smoking remain relatively understudied. This study used a form of network analysis to gain insight into the causal attributions for smoking of both smoking and non-smoking college students. The analyses resu...

Periodontitis is one of the most common oral inflammatory diseases, and results in connective tissue degradation and gradual tooth loss. It manifests with formation of periodontal pockets, in which anaerobic and Gram‑negative bacteria proliferate rapidly. Consequently, alteration of the subgingival microbiota is considered the primary etiologic agent of periodontitis. Previous studies have repo...
