Association of sleep-disordered breathing and alcohol consumption with hypertension among Japanese male bus drivers.

There is limited evidence regarding the combined effects of sleep-disordered breathing (SDB) and alcohol consumption on hypertension. The aim of this study was to examine the combined effects of SDB and alcohol consumption on hypertension in Japanese male bus drivers. This cross-sectional study included 2525 Japanese male bus drivers aged 20-65 years.

Work-family conflict and insomnia symptoms among women working in aged care services in Japan.

Objective: The association between work-family conflict and insomnia has not been thoroughly studied. Therefore, we sought to examine the relationship between work-family conflict and insomnia symptoms among Japanese working women.

Methods: In a cross-sectional study, 608 women aged 18-60 years old who worked in aged care services between 2015 and 2016 were selected, and 445 of these women were ultimately included.

Risk factors for resignation from work after starting infertility treatment among Japanese women: Japan-Female Employment and Mental health in Assisted reproductive technology (J-FEMA) study.

Objective: To elucidate the risk factors associated with resignation from work of Japanese women undergoing infertility treatment.

Methods: A total of 1727 female patients who attended a private fertility clinic in Japan participated in the Japan-Female Employment and Mental health in Assisted reproductive technology study. Questions related to demographic, clinical and socioeconomic characteristics were employed in the questionnaire.

Self-assessed health and menopausal symptoms among 50-year-old Japanese women: cross-sectional surveys in Northern Kawasaki in 1998 and 2008.

Objective: The aim of this study was to determine whether self-assessed health changed over the last decade in association with menopausal symptoms among community-dwelling Japanese women.

Methods: Cross-sectional surveys of 50-year-old women living in Northern Kawasaki were conducted in 1998 (n = 1,492) and 2008 (n = 1,274).

Proliferation of mitogen-stimulated human peripheral blood mononuclear cells is inhibited by extracellular arginine deiminase of Granulicatella elegans isolated from the human mouth.

Granulicatella elegans is a member of normal human oral flora and is thought to be a potent pathogen in endocarditis, especially so-called "culture-negative" endocarditis. To elucidate the pathogenicity of this microorganism in inflammatory diseases, the effect of the extracellular products of this bacteria on human peripheral blood mononuclear cells (PBMCs) was examined. Culture supernatants produced by oral isolates of G.

Employing dmft score as a risk predictor for caries development in the permanent teeth in Japanese primary school girls.

The aim of this study was to examine the significance of evaluating dmft for predicting the incidence of permanent teeth caries in Japanese girls. The subjects were two birth cohorts in a Primary girls' school: cohort I composed of 45 girls born in 1981 and 1982 and cohort II composed of 53 girls born in 1989 and 1990.

Nicotine and lipopolysaccharide stimulate the formation of osteoclast-like cells by increasing macrophage colony-stimulating factor and prostaglandin E2 production by osteoblasts.

Several studies have indicated that one of the causes of alveolar bone destruction with periodontitis is lipopolysaccharide (LPS) from the cell wall of Gram-negative bacteria in plaque and that tobacco smoking may be an important risk factor for the development and severity of periodontitis. The present study was undertaken to determine the effect of nicotine and LPS on the expression of macrophage colony-stimulating factor (M-CSF), osteoprotegerin (OPG), and prostaglandin E2 (PGE2) in osteoblasts, and the indirect effect of nicotine and LPS on the formation of osteoclast-like cells. Saos-2 cells were cultured with 10(-3) M nicotine, or 1 or 10 microg/ml LPS and 10(-3) M nicotine, for up to 14 days.
