Acute effects of strength exercises and effects of regular strength training on cell free DNA concentrations in blood plasma.
2017
Creatine kinase (CK) is a marker for muscle cell damage with limited potential as marker for training load in strength training. Recent exercise studies identified cell free DNA (cfDNA) as a marker for aseptic inflammation and cell damage. Here we overserved in a pilot study the acute effects during strength exercise and chronic effects of regular strength training on cfDNA concentrations over a period of four weeks in three training groups applying conservation training (CT) at 60% of the 1 repetition maximum, high intensity-low repetition training (HT) at 90% of the 1 repetition maximum and differential training (DT) at 60% of the 1 repetition maximum. EDTA-plasma samples were collected b…

Impact of antenatal glucocorticoid therapy and risk of preterm delivery on intelligence in term-born children
2015
Context: Women at risk of preterm delivery are routinely treated with synthetic glucocorticoids (sGCs). Although this therapy substantially reduces neonatal morbidity, concerns remain whether sGC excess may disrupt neurodevelopmental trajectories underlying cognitive functioning. Objective: The present study is the first to disentangle direct effects of antenatal sGC treatment on possible long-term cognitive disadvantages from those of pregnancy complications and prematurity. Design, Setting, and Participants: This cross-sectional study included a mixed-sex cohort of 222 term-born children (aged 6–11 years) consisting of three groups: children of mothers admitted to hospital for threatening…
A case-control study on lip cancer risk factors in Ragusa (Sicily).
1984
Incidence rates of lip cancer in males in Ragusa (Sicily) are amongst the highest in Europe [age-standardized rate (world) for 1980-82: 7.5 per 100,000]. A case-control study was conducted on 53 male cases and 106 controls matched for sex, age (+/- 2 1/2 years), residence and hospital from which cases had been drawn. Individual interviews were carried out for the evaluation of ethnic, environmental, pathologic and occupational risk factors. Lip cancer was significantly associated with: fair, brown, or red hair (relative odds = 2.3), blue eyes (r.o. = 5.3), fair skin (r.o. = 8.0), sensitivity to sunburns (r.o. = 4.1), working outdoors (r.o. = 4.9), coexistence of non-specific lesions of expo…
Relationships of working conditions, health problems and vehicle accidents in bus rapid transit (BRT) drivers
2018
Background The aim of this study was to estimate accident risk rates and mental health of bus rapid transit (BRT) drivers based on psychosocial risk factors at work leading to increased stress and health problems. Methods A cross-sectional research design utilized a self-report questionnaire completed by 524 BRT drivers. Results Some working conditions of BRT drivers (lack of social support from supervisors and perceived potential for risk) may partially explain Bogota's BRT drivers' involvement in road accidents. Drivers' mental health problems were associated with higher job strain, less support from co-workers, fewer rewards and greater signal conflict while driving. Conclusions To preve…
The Construct of Sexual Openness for Females in Steady Intimate Relationships
2017
The analysis of open-minded attitudes towards sexuality in general requires a construct based on attitudinal dimensions. Although several existing studies involve sexual attitudes, they differ substantially and standardized conceptual work is missing. Thus, the authors introduce the latent variable sexual openness to develop a construct based on self-oriented attitudes towards different sexual topics. Available survey data of female German students in a steady relationship allowed providing a first empirical test for the applicability of this construct. Five subdimensions are acknowledged central for sexual openness: sexual practices, masturbation, bisexuality, permissiveness, and pornograp…
Want a tip? Service performance as a function of emotion regulation and extraversion.
2011
Surface acting and deep acting with customers are strategies for service performance, but evidence for their effectiveness is limited and mixed. We propose that deep acting is an effective strategy for most employees, whereas surface acting's effect on performance effectiveness depends on employee extraversion. In Study 1, restaurant servers who tended to use deep acting exceeded their customers' expectations and had greater financial gains (i.e., tips) regardless of extraversion, whereas surface acting improved tips only for extraverts, not for introverts. In Study 2, a call center simulation, deep acting improved emotional performance and increased the likelihood of extrarole service beha…
Tracing patterns of activity in the human skeleton: an overview of methods, problems, and limits of interpretation.
2009
Studies of patterns of activity in human skeletal remains have grown in number over the last few years. Different methods have been used to reconstruct activity patterns in past populations. In this review of the available literature the common themes of these studies have been isolated in order to show that many studies do not truly conform to the standards of the field. Inadequate sample size, too far-reaching conclusions and neglect of other possible explanations are among the problems easily recognised in the literature. Many assumptions are lacking a sound experimental basis, and it becomes increasingly evident that there are many more problems and limits of interpretations than have b…
Methodological Aspects of the Application of the Naka-Rushton Equation to Clinical Electroretinogram
1993
The nonlinear relation between stimulus intensity and response amplitude of the electroretinogram (ERG) scotopic b wave can be described by a curve based on the Naka-Rushton (NR) equation. Up to now, the NR equation has been used to assess the features of the normal and pathological ERG, but the best approach for a correct evaluation of the parameters is still debatable. The parameters are thought to be related to the different conditions of retinal activities. The method is well known in experimental laboratories but is quite unusual at the clinical level. In the present paper the derivative analysis of the NR function is proposed as an easier approach to understand the variations of the N…
Role of Octreoscan and Correlation with MR Imaging in Graves' Ophthalmopathy
1995
Since the identification of somatostatin receptors on lymphocytes, orbital infiltration with mononuclear cells in Graves' ophthalmopathy has provided a rationale for receptor imaging with the radiolabeled somatostatin analog Octreotide. In 40 patients with Graves' ophthalmopathy and 10 controls, 110 MBq indium-Octreotide were administered i.v., and scans were performed at 4 and 24 h after injection. An uptake ratio between the orbits and the brain was determined. In 20 ophthalmophathy patients, magnetic resonance imaging (MRI) of the orbits was performed and the T2 relaxation time was measured within the rectus muscles. Compared to controls (4 h Octreotide uptake: median 6.0 counts/pixel/MB…
