Identifying developmental coordination disorder: MOQ-T validity as a fast screening instrument based on teachers' ratings and its relationship with praxic and visuospatial working memory deficits.
No full textThe present study was devoted to test the validity of the Italian adaptation of the Motor Observation Questionnaire for Teachers (MOQ-T, Schoemaker, Flapper, Reinders-Messelink, & De Kloet, 2008) as a fast screening instrument, based on teachers' ratings, for detecting developmental coordination disorders symptoms and to study its relationship with praxic and visuospatial working memory deficits. In a first study on a large sample of children, we assessed the reliability and structure of the Italian adaptation of the MOQ-T. Results showed a good reliability of the questionnaire and a hierarchical structure with two first-order factors (reflecting motor and handwriting skills), which are influenced by a second-order factor (general motor function) at the top. In a second study, we looked at the external validity of the MOQ-T and found that children with symptoms of Developmental Coordination Disorder (children with high scores on the MOQ-T) also had difficulty reproducing gestures, either imitating others or in response to verbal prompts. Our results also showed that children with high MOQ-T scores had visuospatial WM impairments. The theoretical and clinical implications of these findings are discussed
Italian adaptation of the MOQ-T as a fast screening instrument based on teachers' ratings for identifying developmental coordination disorder symptoms
No full textThe present study was designed to collect data on the Italian adaptation of the Motor Observation Questionnaire for Teachers (MOQ-T, Schoemaker, Flapper, Reinders-Messelink, & De Kloet, 2008). We provide data for 2nd, 3rd, 4th and 5th grades, in some cases distinguishing males from females. On the basis of the present and previous evidence (Giofrè et al., 2014) the MOQ-T appears a valid and a fast screening instrument for detecting developmental coordination disorders (DCD) symptoms (on the basis of teachers' ratings) in children and can be very important as a first step in the process for diagnosing DCD

Charles Prosper Wolff Schoemaker & Vincent Van Romondt: Modernism and national characteristics
No full textIn this booklet, the architectural theorist and Professor at York University Abidin Kusno discusses two lectures given by two influential professors in the former Dutch colony of Indonesia. The first one, ‘The aesthetics of architecture and the art of the moderns’, was given by C. Wolff Schoemaker in 1930. The second, entitled ‘Towards an Indonesian Architecture’, was delivered by Vincent Van Romondt in 1954. Schoemaker and Van Romondt held different views on the challenges of architecture in the world as well as in Indonesia. They nevertheless both sought to bring the notion of modernism and tradition into the context of their time. The lectures are published here for the first time in English

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The role of calcitonin gene-related peptide (CGRP) in ischemic preconditioning in isolated rat hearts
No full textBrief coronary artery occlusion can protect the heart against damage during subsequent prolonged coronary artery occlusion; ischemic preconditioning. The role of calcitonin gene-related peptide (CGRP) in ischemic preconditioning is investigated in isolated perfused rat hearts, by measuring CGRP release during ischemic preconditioning and mimicking this by exogenous CGRP infusion, either in the absence or presence of the CGRP antagonist BIBN4096BS. CGRP increased left ventricular pressure and coronary flow in a concentration dependent manner, which was effectively antagonized by BIBN4096BS. Rat hearts (n = 36) were subjected to 45 min coronary artery occlusion and 180 min reperfusion, which was preceded by: (1) sham pretreatment, (2) BIBN4096BS infusion (1 mu M), (3) preconditioning by 15 min coronary artery occlusion and 10 min reperfusion, (4) as 3, but with BIBN4096BS, (5) 15 min CGRP infusion (5 nM) and 10 min washout, (6) as 5, but with BIBN4096BS. Cardiac protection was assessed by reactive hyperaemia, creatine kinase release, infarct size related to the area at risk (%), and left ventricular pressure recovery. Preconditioning increased CGRP release into the coronary effluent from 88 +/- 13 to 154 +/- 32 pg/min/g, and significantly protected the hearts by decreasing reactive hyperaemia (35%), reducing creatine kinase release (53%), limiting infarct size (48%), and improving left ventricular pressure recovery (36%). Exogenous CGRP induced preconditioning-like cardioprotection. BIBN completely abolished the cardioprotection induced by preconditioning as well as by exogenous CGRP. In conclusion, since cardioprotection of preconditioning-induced CGRP release can be mimicked by exogenous CGRP, and both can be blocked by a CGRP antagonist, results indicate an important role for CGRP in ischemic preconditioning.

Pharmacological therapy can increase capillary density in post-infarction remodeled rat hearts
No full textObjective: Postinfarction hypertrophied hearts have been shown to display a lower capillary density and reduced mechanical efficiency amplified by tachycardia. We investigated whether pharmacological reduction of postinfarction tachycardia would induce capillary growth by treating myocardial infarcted (MI) rats with aspirin, methylprednisolone, moxonidine or captopril, during the first 3 weeks after infarction. Methods and Results: Effects on in vivo heart rate were measured in Conscious unrestrained rats, while in vitro heart rate effects were evaluated in isolated perfused hearts. Compared to sham-rats, MI-rats manifested a significant in vivo as well as in vitro tachycardia (increase 9% and 20% vs. sham, respectively). Whereas aspirin, methylprednisolone and moxonidine significantly reduced postinfarction in vivo tachycardia, captopril rather increased in vivo heart rate. In vitro tachycardia of MI-hearts was reduced to sham-values with aspirin and methylprednisolone (P <0.05), but not with moxonidine and captopril. Capillary density defined as the number of Lectin stained capillaries per tissue area, which significantly decreased in MI-hearts (decrease 42% vs. sham), was restored by all treatments (P <0.05). Concentric left ventricular hypertrophy after MI, defined as increased cross-sectional area of transversally cut Gomori stained myocytes, was indicated by almost double myocyte size (P <0.05), while capillary to myocyte ratio remained unchanged. Methylprednisolone, moxonidine and captopril, but not aspirin, prevented hypertrophy (P <0.05). However, treatment with aspirin and methylprednisolone, but not moxonidine and captopril, increased capillary to myocyte ratio (P <0.05) Lip to twice the values of non-treated MI hearts, indicating newly formed capillaries. Conclusions: The above findings confirm that post-MI pharmacological treatment can increase capillary density in the remodeled left ventricle. Whereas prevention of left ventricular hypertrophy normalizes capillary density without actually affecting capillary number, increased capillary to myocyte ratio (at preserved hypertrophic response) indicates actual capillary growth.
