Background and aims: Various culture media along with some supplements and enrichment materials have been suggested for in vitro maturation. This study aims to investigate the effect of retinoic acid on nuclear maturation of immature mouse oocytes in vitro. Materials and methods: immature oocytes were obtained from 6-8 weeks old NMRI mice, 48 hours after intraperitoneal injection of 7.5 units ...

Measurement invariance (MI) entails that measurements in different groups are comparable, and is a logical prerequisite when studying difference or change across groups. MI is commonly evaluated using multi-group structural equation modeling through a sequence of chi-square and chi-square-difference tests. However, under the conventional null hypothesis testing (NHT) one can never be confident ...

introduction: several studies have shown the independent association of high plasma c - reactive protein (crp) levels with adverse prognosis in patients with acute myocardial infarction (mi). the aim of this study was to assess the prognostic value of quantitative crp (q-crp) to predict mi in patients with unstable angina. materials & methods: this cohort study was carried out between december ...

BACKGROUND The incidence of myocardial infarction (MI) in Norway has decreased substantially over the last two decades, according to recent publications based on data from the Norwegian Patient Registry. To better understand the development of cardiovascular disease over time we have investigated the development of MI mortality in light of the decrease in MI incidence. MATERIAL AND METHODS Da...

BACKGROUND In the present study, nitric oxide (NO) was investigated to see if it mediated effects of nebivolol on apoptosis in the rat myocardial infarction (MI) model. METHODS AND RESULTS Rats were divided into 3 groups: sham operated (sham-control), MI-induced (MI-control) and nebivolol treated (MI-nebivolol). The initial dose of nebivolol was administrated intravenously (iv) within 10 min ...

Background and Aim: White spot lesions (WSLs) are common occurrence following orthodontic treatment, this study sought to compare the remineralizing potential of fluoride, MI Paste Plus (CPP-ACP-F) and Remin Pro for treatment of WSLs. Materials and Methods: This in vitro study was conducted on 56 sound human premolars that extracted for orthodontic purposes. Teeth were cleaned and their root...

background: myocardial infarction (mi) is a main cause of death and disability worldwide, whichinvolves a number of genetic, physiopathologic and socio-economic determinants. the aim of thisstudy was to assess the patterns of association between education, wealth and some other risk factorswith non-fatal mi in tehran population.methods: data derived from a second round of large cross-sectional ...

OBJECTIVE To investigate the effects of using motor imagery (MI) in combination with a virtual reality (VR) program on healthy volunteers and stroke patients. In addition, this study investigated whether task variability within the VR-guided MI programs would influence corticomotor excitability. METHODS The present study included 15 stroke patients and 15 healthy right-handed volunteers who w...

It is a matter of debate as to what extent the long-term outcome of cystic fibrosis (CF) is affected by presenting with meconium ileus (MI). We compared long-term clinical outcomes of CF children who presented with MI, to those presenting with other symptoms (non-MI) in an era of non new-born-screening (NBS).We collected annual lung function data between the ages of 8-15 years in terms of perce...
