BACKGROUND The aim of the study was to identify differences in psychological characteristics between couples with fertility disorders, especially idiopathic infertility, and a representative sample. MATERIAL AND METHODS A total of 564 couples was examined using psychological questionnaires pertaining to sociodemographic factors, motives for wanting a(More)
A 56-kDa protein isolated from the mucus of the European sea hare Aplysia punctata shows a prefer ential toxicity to autonomously growing transformed mammalian cells. Cell death induced by this protein differs from both apoptosis and necrosis. The cytotoxic effects are irreversible and become apparent at nanomolar concentrations in a cell type-dependent(More)
BACKGROUND & AIMS Leukocyte telomere length (LTL) shortens with age and short LTL has been associated with increased mortality and increased risk for some age-related outcomes. This study aims to analyse the associations of smoking habits with LTL and rate of LTL change per year in older adults. METHODS LTL was measured by quantitative PCR at baseline in(More)
Both telomere length and frailty were observed to be associated with aging. Whether and to what extent telomere length is related to frailty is essentially unknown. In this cross-sectional analysis of baseline data of 3537 community-dwelling adults aged 50 to 75 years of a large German cohort study, we assessed the hypothesis that shorter telomere length(More)
OBJECTIVE Telomere length (TL) has been proposed as a biomarker of ageing, which might be used to identify individuals at higher risk of age-related diseases. Obesity is a well-known risk factor for several diseases. This study aims to analyse the associations of BMI with TL and the rate of TL change in older adults. METHODS Leukocyte TL (LTL) was(More)
The C1D gene is expressed in a broad spectrum of mammalian cells and tissues but its product induces apoptotic cell death when exceeding a critical level. Critical levels are achieved in a fraction of cells by transient transfection with EGFP-tagged C1D expression constructs. However, transfected cells expressing sub-critical levels of C1D(EGFP) escape(More)
Little is known about prognostic factors in the treatment of bulimic patients. In the context of an ongoing study we looked at 1-year symptomatic outcome of 37 outpatients fulfilling DSM-III-R criteria for bulimia nervosa in relation to a variety of measures at first assessment. These included multiple measures of depression, measures of borderline(More)
