Father's Impact on Son's Gender Role Identity
1992
ABSTRACT The study investigates the similarities between the gender role identities of 12 year‐old boys and their fathers. An attempt was also made to determine the influence of father‐son interaction on the specific nature of these similarities. The study was carried out in Jyvaskyla and the subjects comprised 113 12 year‐old boys and their fathers. The sex role orientation of fathers and their sons was measured by a sex role inventory designed for the study. Father — son correlations were studied in relation to the frequency and quality of father‐son interaction, especially with regard to the paternal warmth and paternal control involved. The son's masculinity correlated positively with t…
Facilitators, teachers, observers, and play partners : Exploring how mothers describe their role in play activities across three communities
2019
The present study explored the perspectives of mothers from three communities regarding their role in play activities with their toddlers. The mothers of two-year-old children from Muenster, Germany (n = 34), Chennai, India (n = 36), and New York City, USA (n = 36), participated in the study. Qualitative content analysis was utilized to analyze the mothers' responses to semi-structured interview questions. Four roles were identified as characterizing the mothers' narratives, namely mothers as facilitators, teachers, play partners, or observers. The goal of facilitator was to support children's autonomy; teachers often described educational learning goals; and play partners and observers hig…
The relationships between school belonging and students’ motivational, social-emotional, behavioural, and academic outcomes in secondary education: a…
2019
This meta-analytic review examines the relationships between students' sense of school belonging and students' motivational, social-emotional, behavioural, and academic functioning in secondary education. Moreover, it examines to what extent these relationships differ between different student groups (grade level, SES), measurement instruments, and region. The meta-analysis included 82 correlational studies, published in peer-reviewed journals between 2000 and 2018. Results revealed, on average, a small positive correlation with academic achievement, and small to moderate positive correlations with motivational outcomes such as mastery goal orientations; with social-emotional outcomes such …
Data from: Evolution of male and female choice in polyandrous systems
2017
We study the evolution of male and female mating strategies and mate choice for female fecundity and male fertilization ability in a system where both sexes can mate with multiple partners, and where there is variation in individual quality (i.e. in the availability of resources individuals can allocate to matings, mate choice and production of gametes). We find that when the cost of mating differs between sexes, the sex with higher cost of mating is reluctant to accept matings and is often also choosy, while the other sex accepts all matings. With equal mating costs, the evolution of mating strategies depends on the strength of female sperm limitation, so that when sperm limitation is stro…
Cinnamaldehyde Induces Expression of Efflux Pumps and Multidrug Resistance in Pseudomonas aeruginosa
2019
Essential oils or their components are increasingly used to fight bacterial infections. Cinnamaldehyde (CNA), the main constituent of cinnamon bark oil, has demonstrated interesting properties in vitro against various pathogens, including Pseudomonas aeruginosa. In the present study, we investigated the mechanisms and possible therapeutic consequences of P. aeruginosa adaptation to CNA. Exposure of P. aeruginosa PA14 to subinhibitory concentrations of CNA caused a strong albeit transient increase in the expression of operons that encode the efflux systems MexAB-OprM, MexCD-OprJ, MexEF-OprN, and MexXY/OprM. This multipump activation enhanced from 2- to 8-fold the resistance (MIC) of PA14 to …
The effects of ezetimibe on LDL-cholesterol: quantitative or qualitative changes ?
2009
Ezetimibe represents the first of a new class of agents, the cholesterol absorption inhibitors, able to reduce low-density lipoproteins (LDL)-cholesterol by 15-25% from baseline in monotherapy and on top of statins and fibrates. To-date all the data regarding the efficacy of ezetimibe comes from the studies of its lipid-lowering power. Yet, recent findings from the ENHANCE study on atherosclerosis progression showed that the addition of ezetimibe to simvastatin in patients with heterozygous familial hypercholesterolemia did not affect the mean change in carotid intima-media thickness, although a significant reduction in LDL-cholesterol levels was present. Therefore, we cannot exclude that e…
Choosing an ideal pharmacotherapeutic strategy for dyslipidemia in children.
2018
Dyslipdiemia can manifest at a young age, and it is a risk factor for atherosclerotic cardiovascular disease (ASCVD), the principal cause of mortality in developed nations. Therefore, treating it a...
Blocking Jak/STAT signalling using tofacitinib inhibits angiogenesis in experimental arthritis
2021
Abstract Objective During rheumatoid arthritis (RA), the angiogenic processes, occurring with pannus-formation, may be a therapeutic target. JAK/STAT-pathway may play a role and the aim of this work was to investigate the inhibiting role of a JAK-inhibitor, tofacitinib, on the angiogenic mechanisms occurring during RA. Methods After ethical approval, JAK-1, JAK-3, STAT-1, STAT-3 and VEGF expression was evaluated on RA-synovial-tissues. In vitro, endothelial cells (ECs), stimulated with 20 ng/ml of VEGF and/or 1 μM of tofacitinib, were assessed for tube formation, migration and proliferation, by Matrigel, Boyden chamber assay and ki67 gene-expression. In vivo, 32 mice received collagen (coll…
Quantitative and qualitative effects of rosuvastatin on LDL-cholesterol: what is the clinical significance ?
2009
Summary Background: Statins have emerged as the global leader in pharmacologic therapy for dyslipidaemia, and rosuvastatin has demonstrated clinical efficacy as well as safety in several clinical trials and postmarketing analyses. Aim: The present article reviewed the effects of rosuvastatin on the quantity and the quality of low-density lipoproteins (LDL). Methods: We searched for and reviewed all the available evidence in a systematic way. A literature search (by Medline and Scopus) was performed using the following headings: ‘LDL-cholesterol’, ‘LDL size’, ‘LDL subclasses’, ‘small dense LDL’, ‘apolipoprotein B, apo B’ and ‘rosuvastatin’ up to 11 November 2008. The authors also manually…
Food as medicine in psychiatric care: Which profession should be responsible for imparting knowledge and use of omega-3 fatty acids in psychiatry
2011
Accepted version of an article in Complementary Therapies in Clinical Practice, 17 (2011), 107-112. Also available from the publisher: http://dx.doi.org/10.1016/j.ctcp.2010.08.001 The effect of omega-3 fatty acids on depression is well documented. The purpose of this study was to determine if and how food is used as medicine in psychiatric care, especially how omega-3 fatty acids are used as a supplement in the treatment of depression. This is a pilot study with a qualitative design using questionnaires and interviews among nursing students, tutor nurses and psychiatrists. Three main categories emerged: 1. Nutrition is considered important but few evaluations are made. 2. There was a lack o…
