OBJECTIVES The objective of this study was to examine the sex (gender) differentiation of indirect self-destructiveness intensity and its manifestations, as well as relationships between indirect self-destructiveness and its manifestations (categories) and the psychological dimensions of masculinity and femininity, also from the point of view of assessing occupational health and safety.

AIM Behaviours causing harm to a subject are generally called self-destructive behaviours. For some time now direct/acute self-destructiveness and indirect/chronic self-destructiveness have been distinguished. Human activity is determined to a large degree by not only biological (somatic) sex but also psychological gender. The aim of the study was to examine relationships between indirect self-...

OBJECTIVES To assess the associations between gender roles and depression in older men and women and whether gender roles are independent risk factors for depression. METHODS International cross-sectional study of adults between 65 and 74 years old (n = 1,967). Depression was defined by a score of 16 or over in the Center for Epidemiologic Studies Depression Scale (CES-D). A validated 12-item...

INTRODUCTION Ten viral genotypes (A-J) distributed in all continents have been described for hepatitis B virus (HBV). One of the methodologies for determining the viral genotype is the restriction fragment length polymorphism (RFLP) technique, a simple and relatively inexpensive method, albeit with some limitations. OBJECTIVE The initial objective of the project was to identify the HBV genoty...

BACKGROUND Previous studies have shown that personality characteristics affect sexual functioning. The aim of this exploratory study was to assess and describe the relationship between global personality traits and the stereotypical femininity and masculinity levels with the broad aspects of sexual behaviours and attitudes in the group of 97 heterosexual young adult men aged 19-39 and living in...

BsrDI and BtsI restriction endonucleases recognize and cleave double-strand DNA at the sequences GCAATG (2/0) and GCAGTG (2/0), respectively. We have purified and partially characterized these two enzymes, and analyzed the genes that encode them. BsrDI and BtsI are unusual in two respects: each cleaves DNA as a heterodimer of one large subunit (B subunit) and one small subunit (A subunit); and,...
