Opettajien ammatillinen identiteetti, toimijuus ja sitoutuminen väljä- ja tiukkakytkentäisessä koulutusorganisaatiossa

2012

This article examines teachers’ work and their professional identity negotiations in two different organisation: a vocational institute and a university department of teacher education. It illustrates how the administrative regulation of educational organisations can restrict and support teachers’ professional orientation, agency and commitment to their own organisation. The research data consisted of 24 open-ended narrative interviews, which were analysed applying qualitative content analysis and thematic analysis. The analysed organisations represent different ways of managing and controlling teachers’ work, which lead the researchers to describe one of them a loosely-coupled organisation…

A novel nutrient blend mimics calorie restriction transcriptomics differentially in multiple tissues of mice

2017

Identification of caloric restriction mimetics (CRMs), compounds that mimic the beneficial effects of caloric restriction (CR) without restriction of dietary energy would be an advancement in anti-aging science. The present study investigated whether the transcriptional profiles of a putative CRM nutrient blend could mimic that of CR in diverse tissues following long-term feeding in B6C3F1 male mice. Study design: Young Controls (YC; 5 mo.) and 3 groups treated from 14-30 mo.: Old Controls (OC), Old CR (OCR; 25% CR) and Old Supplemented (OS); n=7/group. Gene expression profiling in cerebral cortex (CCT), skeletal muscle (gastrocnemius)(SKL), heart (HRT), white adipose tissue (WAT) and liver…

Exercise, the endocannabinoid system and metabolic health

2013

As obesity and associated metabolic disorders, such as type 2 diabetes and dyslipidemia, are becoming one of the most serious health problems worldwide, development of effective therapies is a high priority. In the search for treatments, the recently discovered endocannabinoid system (ECS) has begun to garner attention, and a wealth of research is now focusing on this unique neuromodulatory system named after the plant that led to its discovery. The ECS consists of G protein-coupled cannabinoid receptors (CB1 and CB2), their endogenous lipid-derived ligands (endocannabinoids, N-arachidonoylethanolamine, named anandamide (AEA) and 2-arachidonoylglycerol (2-AG)) and the enzymes for ligand syn…

Distribution of Ha-ras alleles in patients with colorectal cancer and Crohn's disease.

1991

The allele distribution of the Ha-ras gene on chromosome 11p was analysed by the restriction fragment length polymorphism of the enzymes Mspl/Hpall in 238 individuals. The investigation covered 116 patients with colorectal carcinoma and 122 patients with Crohn's disease, representing two patient populations with the same ethnic origin, one with a malignant and the other a benign disease of the same organ system. A total of 17 different alleles were detected belonging to the common, intermediate, and rare classes according to the original nomenclature of Ha-ras alleles. Patients with Crohn's disease showed no difference in the distribution of Ha-ras alleles when compared with expected freque…

The Effects of Restriction Pressures on the Acute Responses to Blood Flow Restriction Exercise

2019

Purpose: No current guidelines or recommendations exist informing the selection of restriction pressure during blood flow restriction exercise (BFRE). Moreover, the effects of specific relative restriction pressures on the acute muscle, metabolic and cardiopulmonary responses to BFRE are unclear. The purpose of this study was to characterize these acute responses at different levels of restriction pressure. Methods: Participants (n = 10) completed rhythmic isometric knee extension exercise across five experimental trials in a balanced randomized order. Three were BFRE trials {B-40 [restriction pressure set to 40% LOP (total limb occlusion pressure)]; B-60 (60% LOP); and B-80 (80% LOP)) with…

The Mediterranean diet improves the systemic lipid and DNA oxidative damage in metabolic syndrome individuals. A randomized, controlled, trial.

2013

Summary Background & aims Metabolic syndrome (MetS), in which a non-classic feature is an increase in systemic oxidative biomarkers, presents a high risk of diabetes and cardiovascular disease (CVD). Adherence to the Mediterranean Diet (MedDiet) is associated with a reduced risk of MetS. However, the effect of the MedDiet on biomarkers for oxidative damage has not been assessed in MetS individuals. We have investigated the effect of the MedDiet on systemic oxidative biomarkers in MetS individuals. Methods Randomized, controlled, parallel clinical trial in which 110 female with MetS, aged 55–80, were recruited into a large trial (PREDIMED Study) to test the efficacy of the traditional MedDie…

The purpose of this study was to investigate the prevalence of self-reported restrictive eating, current or past eating disorder, and menstrual dysfunction and their relationships with injuries. Furthermore, we aimed to compare these prevalences and associations between younger (aged 15–24) and older (aged 25–45) athletes, between elite and non-elite athletes, and between athletes competing in lean and non-lean sports. Data were collected using a web-based questionnaire. Participants were 846 female athletes representing 67 different sports. Results showed that 25%, 18%, and 32% of the athletes reported restrictive eating, eating disorders, and menstrual dysfunction, respectively. Higher ra…

Comparison of the ability of alternative birthweight and fetal weight standards to identify preterm newborns at increased risk of perinatal death

2013

Objective To compare prediction of perinatal deaths among preterm infants based on fetal weight standards versus a new subpopulation-based birthweight standard. Design Population-based cohort study. Setting France. Population A total of 9100 preterm singletons, born between 24 and 36 weeks of gestation in 2000–09, in Burgundy (France). Methods We first classified all newborns as either small for gestational age (SGA) or not, based on alternative fetal weight or birthweight standards, including a new birthweight standard that excludes infants born to mothers with disease related to the weight of a fetus. Based on discrepancies between the different classifications, we then divided the newbor…

Effect of CYP1A1 Gene Polymorphisms on Estrogen Metabolism and Bone Density

2004

UNLABELLED: In this study, we evaluated the effect of polymorphisms of the CYP1A1 gene, linked to hormone-related cancers, on estrogen metabolism and BMD. We found that variants carrying the A allele (CA and AA) for the C4887A polymorphism have a significantly higher degree of estrogen catabolism and lower femoral BMD. INTRODUCTION: Polymorphisms of the CYP1A1 gene, one of the key enzymes that metabolize estrogen, have been linked with hormone-related cancers. We investigated the impact of these polymorphisms on estrogen metabolism and BMD, which is another hormone-dependent health issue. MATERIALS AND METHODS: One hundred seventy postmenopausal women (mean age, 63.5 +/- 0.6 years) particip…
