Physical Activity of Children With and Without Long-Term Illness or Disability

2011

Background:We know very little about physical activity in children with long-term illness or disability compared with those children without disabilities. Previous studies indicate low physical activity levels among all adolescents.Methods:The sample consisted of Canadian (n = 2720) and Finnish pupils (n = 3459) approximately 13.5 and 15.5 years of age in general (mainstreamed) education. The study is a part of the Health Behavior in School-aged Children (HBSC) study. Nationally representative data were collected in 2002 using a standardized questionnaire. The moderate-to-vigorous intensity physical activity screening measure was used.Results:Approximately one-fifth of the pupils in both co…

Smoking trends among adolescents from 1990 to 2002 in ten European countries and Canada.

2006

Abstract Background Daily smoking adolescents are a public health problem as they are more likely to become adult smokers and to develop smoking-related health problems later on in their lives. Methods The study is part of the four-yearly, cross-national Health Behaviour in School-aged Children study, a school-based survey on a nationally representative sample using a standardised methodology. Data of 4 survey periods are available (1990–2002). Gender-specific daily smoking trends among 14–15 year olds are examined using logistic regressions. Sex ratios are calculated for each survey period and country. Interaction effects between period and gender are examined. Results Daily smoking preval…

Una tipología de desajustes entre competencias y educación utilizando un análisis comparativo entre países

2015

This paper aims to discuss the value of the diplomas and the situation of downgrading on the labour market. Its novelty is to compare skills both acquired and required in employment, using a self - assessment carried out by young higher education graduates a cross nine countries of Europe, Japan and Canada. More precisely, we illustrate the incidences of diploma and skill mismatches using three higher education graduate surveys, two international surveys (CHEERS, REFLEX) and a Canadian survey (NGS). We define possible over - education and skill mismatches and then present an empirical typology to show the most frequent cases of mismatches. The ideal situation which corresponds to a perfect …

Neonatal Outcomes and Long-Term Follow-Up of Children Born from Frozen Embryo, a Narrative Review of Latest Research Findings

2022

In recent years, the growing use of ART (assisted reproductive techniques) has led to a progressive improvement of protocols; embryo freezing is certainly one of the most important innovations. This technique is selectively offered as a tailored approach to reduce the incidence of multiple pregnancies and, most importantly, to lower the risk of developing ovarian hyperstimulation syndrome when used in conjunction with an ovulation-triggering GnRH antagonist. The increase in transfer cycles with frozen embryos made it possible to study the effects of the technique in children thus conceived. Particularly noteworthy is the increase in macrosomal and LGA (large for gestational age) newborns, i…

Cryopreserved primary hepatocytes as a constantly available in vitro model for the evaluation of human and animal drug metabolism and enzyme inductio…

2000

The use of primary hepatocytes is now well established for both studies of drug metabolism and enzyme induction. Cryopreservation of primary hepatocytes decreases the need for fresh liver tissue. This is especially important for research with human hepatocytes because availability of human liver tissue is limited. In this review, we summarize our research on optimization and validation of cryopreservation techniques. The critical elements for successful cryopreservation of hepatocytes are (1) the freezing protocol, (2) the concentration of the cryoprotectant [10% dimethyl-sulfoxide (DMSO)], (3) slow addition and removal of DMSO, (4) carbogen equilibration during isolation of hepatocytes and…

Ronneburgite, K2MnV4O12, a new mineral from Ronneburg, Thuringia, Germany: Description and crystal structure

2001

Ronneburgite is a new chain vanadate mineral from Ronneburg, Thuringia, Germany. It occurs as reddish-brown crystals of equant, flattened, or short prismatic habit, up to 0.5 mm in length. The crystals have an adamantine luster and are translucent. Ronneburgite is biaxial negative with refractive indices n α = 1.925(5), n β = 1.960(10), n γ = 1.988(4), and 2 V x = 82°. Electron microprobe analysis (K 2 O = 16.93, MnO = 12.44, MgO = 0.62, V 2 O 5 = 68.54; total = 98.53 wt%) gives the empirical formula K 1.91 Mn 0.93 Mg 0.08 V 4.00 O 11.96 , which simplifies to K 2 MnV 4 O 12 . Ronneburgite is mono-clinic, space group P 2 1 / n , with a = 8.183(3), b = 9.247(3), c = 8.651(2) A, and β = 109.74…
