Association Between Passive Smoking and Menstrual Discomfort: A Cross-Sectional Study of 2,571 Non-smoking Chinese Nurses.

Introduction: Menstrual discomfort affects women's quality of life, which is an important public health issue. Evidence confirming the link between passive smoking and menstrual discomfort is limited. Therefore, the aim of this study is to investigate the aforementioned topic on the basis of a cross-sectional study of 2,571 non-smoking Chinese nurses.

Association Between Passive Smoking and Health Among Chinese Nurses: A Cross-Sectional Study.

This study aimed to investigate the association between passive smoking and physical and psychological health in Chinese nurses. Participants of this cross-sectional study comprised 2,484 non-smoking nurses. Passive smoking and demographic information were assessed using a self-administered questionnaire.

Constructing an integrated gene similarity network for the identification of disease genes.

Background: Discovering novel genes that are involved human diseases is a challenging task in biomedical research. In recent years, several computational approaches have been proposed to prioritize candidate disease genes. Most of these methods are mainly based on protein-protein interaction (PPI) networks.

[Genotyping of 210 Mycobacterium tuberculosis strains with Spoligotyping and MIRU-VNTR among pediatric tuberculosis patients in Chongqing].

Objective: To evaluate the application of spacer oligonucleotide typing (Spoligotyping) and mycobacterial interspersed repetitive unit-variable-number tandem repeat (MIRU-VNTR) analysis in the molecular-epidemiological study of tuberculosis and to discuss the characteristics of pediatric Mycobacterium (M.) tuberculosis strains in Chongqing.

Methods: M.

[Monocyte chemotactic protein-1 gene polymorphism and monocyte chemotactic protein-1 expression in Chongqing Han children with tuberculosis].

Objective: The aims of this study were to evaluate whether the presence of -2518A/G polymorphism in the distal regulatory region of the monocyte chemotactic protein-1 (MCP-1) was associated with tuberculosis (TB) in Chongqing Han population and to find whether it has a significant impact on the pediatric patient.

Method: One hundred children [ < or = 15 years old, mean age (7.3+/-4.

Combined MBR with photocatalysis/ozonation for bromoamine acid removal.

A combined biological (augmented membrane bioreactor (MBR)) and photochemical (photocatalysis and ozonation) treatment has been proposed for bromoamine acid (BAA) removal in dyeing wastewater. It was demonstrated that the color and chemical oxygen demand removal in the sequential augmented MBR was about 90% and 50%, respectively. By ribosomal intergenic spacer analysis, it was found that the introduced strain QYY was maintained as the predominant species and the diversity of the system was relatively low throughout the operation.

Population dynamics in bioaugmented membrane bioreactor for treatment of bromoamine acid wastewater.

The performances and microbial population changes in laboratory-scale membrane bioreactor (MBR) augmented with Sphingomonas xenophaga QYY were investigated in the present study. It was demonstrated that after 30 days acclimation, the non-augmented MBR system were able to degrade bromoamine acid (BAA) well. However, the efficiency of the system decreased with BAA concentration increasing.
