Prevalence and distribution of coronary calcium in asymptomatic Japanese subjects in lung cancer screening computed tomography.

Background: Coronary artery calcium (CAC) is associated with a risk of coronary heart disease. The prevalence and distribution of the CAC score have been examined in Western countries, but few studies have been performed in Asia, and especially in Japan. The goal of this study was to investigate CAC scores in an asymptomatic Japanese population.

Surveillance of chronic obstructive pulmonary disease in high-risk individuals by using regional lung cancer mass screening.

Background And Objective: Patients with chronic obstructive pulmonary disease (COPD) are at risk for lung cancer; the diseases have common etiologies, including cigarette smoking. We aimed to clarify the effectiveness of COPD detection using a regional mass-screening program for lung cancer.

Materials And Methods: A total of 7,067 residents of Togane, Chiba, Japan received lung cancer screening between May and July, 2011.

[Exploring the link between standard lifestyle questionnaires administered during specific medical check-ups and incidence of metabolic syndrome in Chiba Prefecture].

Objectives: The aim of this study was to clarify the relationship between standard lifestyle questionnaires and the development of metabolic syndrome (MetS).

Methods: We analyzed the data on 278,989 people (111,524 males and 167,465 females) living in Chiba Prefecture who underwent consecutive medical check-ups in 2008 and 2009. The standard lifestyle questionnaire administered during the check-ups consisted of 10 items, including three on exercise behaviors, four on dietary behaviors, and one each on drinking, smoking, and sleeping behaviors.

Study of experiment on leaching of bisphenol A from infant books to artificial saliva.

Objective: To assess the risk of bisphenol A (BPA) exposure when infants suck or chew infant books, the concentration of BPA leaching from infant books published by Japanese makers to artificial saliva was measured.

Methods: The concentration of BPA leaching from 10 infant books to 15 ml artificial saliva or water was measured at 37 degrees C for 20 hrs. BPA concentration was measured by high-performance liquid chromatography-electrochemical detection (HPLC-ECD) with solid-phase extraction.

Effects of bisphenol A on the development, growth, and sex ratio of the housefly Musca domestica.

The effects of bisphenol A (BPA) on the life cycle of the housefly Musca domestica were examined. The sex ratio of the imago shifted in favor of males when eggs and larvae were exposed to BPA in culture media at concentrations of 1,000 microg kg(-1) for five generations and 100 microg kg(-1) for seven generations. Notably, at an initial concentration of 100 microg kg(-1), BPA levels in the growth medium decreased 61% at 4 h after egg inoculation, and no BPA was detected after 24 h.

Determination of Bisphenol A (BPA) in Plasma of Hemodialysis Patients Using Three Methods: LC/ECD, LC/MS, and ELISA.

ABSTRACT Bisphenol A (BPA) values were compared in plasma of hemodialysis patients and in recycling solvents using LC/MS, LC/electrochemical detector (ECD), and enzyme linked immunosorbent assay (ELISA). BPA values in the plasma and the solvent were 0-8.4 ng/ml and 0-0.

[Relationship of normal levels of activity of daily living and daily habits among elderly women at home].

Purpose: The relationship of activities of daily living (ADL) with daily habits and age was investigated with a focus on the results of measurements of the normal speed (ordinary level: OL) and maximum speed (maximum capacity: MC) in performing items on a functional fitness test. The significance of the measurement of the ordinary level was also discussed.

Methods: The subjects were 69 women, aged 60-90 years old, who participated in a health workshop for the elderly sponsored by a local municipality and who performed at least 4 items on a functional fitness test.
