INVERSE RELATIONSHIP BETWEEN AORTIC ROOT DIAMETER AND RENAL FUNCTION IN HYPERTENSIVE SUBJECTS
2015
Introduction: Dilatation of aortic root is associated with presence and severity of aortic regurgitation and risk for aortic dissection. Recent studies performed in general population suggest that enlarged aortic root diameter (ARD) may predict cardiovascular events in absence of aneurysmatic alterations. Little is known about the influence of renal function on ARD. Aim: To assess the relationships between glomerular filtration rate (GFR) and ARD in hypertensive subjects. Methods: We enrolled 611 hypertensive individuals (mean age: 52 ± 15 years; men 63 %) consecutively attending our outpatient nephrology and hypertension unit. Patients on dialysis treatment, with valvulopathy more than mil…
Neck Pain and Rehabilitation
2016
Neck pain is par excellence one of the most common disorders of the musculoskeletal system, second only to low back pain. It constitutes 40 % of all backache. The International Association for the Study of Pain (IASP) defines pain of cervical origin coming from an area between the nuchal line and another imagi-nary line that passes through the lower end of the spinous process of the first thoracic vertebra and the sagittal plans tangent to the side edges of the neck. This definition considers therefore posterior pain which in turn can be divided into high pain, up to C3, and lower pain, down from C4. Also, as all diseases, it can be divided into acute and chronic neck pain, merely according…
Persistence in Italian rate of Unemployment in presence of breaks and regional asymmetries
2006
This work aims to test the persistence of Italian unemployment rate during last fifty years. To this scope we find evidences of a unit root, also when we allow for the presence of structural shifts so that the level of unemployment has a path dependant behaviour. Secondly, we test a possible explanation of the persistence through the presence of cointegration relationships with some institutional labour market variables, such as the union membership. Thirdly, there are asymmetric macroregional behaviours so that the great bulk of persistence is given by Center – Southern unemployment. It implies that changes in unemployment level have longer duration in the poorest part of the country.
Involvement of nitrate reductase and pyoverdine in competitiveness of Pseudomonas fluorescens strain C7R12 in soil
2001
ABSTRACT Involvement of nitrate reductase and pyoverdine in the competitiveness of the biocontrol strain Pseudomonas fluorescens C7R12 was determined, under gnotobiotic conditions, in two soil compartments (bulk and rhizosphere soil), with the soil being kept at two different values of matric potential (−1 and −10 kPa). Three mutants affected in the synthesis of either the nitrate reductase (Nar − ), the pyoverdine (Pvd − ), or both (Nar − Pvd − ) were used. The Nar − and Nar − Pvd − mutants were obtained by site-directed mutagenesis of the wild-type strain and of the Pvd − mutant, respectively. The selective advantage given by nitrate reductase and pyoverdine to the wild-type strain was as…
The adaptation of mechanically softened gutta-percha to the canal walls in the presence or absence of smear layer: a scanning electron microscopic st…
1995
Summary The objective of this study was to compare the adaptation of mechanically softened gutta-percha to the root canal wall in the presence and absence of smear layer. The root canals of 20 freshly extracted human maxillary incisors were cleaned and shaped. Prior to obturation, 10 root canals were irrigated with 20 ml of 50% citric acid followed by 20 ml of 5.25% sodium hypochlorite. All canals were obturated with mechanical compaction of gutta-percha and AH-26 sealer. After 72h, each tooth was fractured in half. Scanning electron microscopy demonstrated that the sealer had formed a continuous layer in contact with the canal walls, becoming progressively thinner towards the apex. The sea…
Intentions to drop-out of youth soccer: A test of the basic needs theory among European youth from five countries
2013
Research arising from self-determination theory (SDT; Deci, E. L., & Ryan, R. M. (2000). The “what” and “why” of goal pursuits: Human needs and the self-determination of behavior. Psychological Inquiry, 11(4), 227–268) indicates that the quality of the social interactions between athletes and coaches, and athletes' ensuing psychological responses, are critical determinants of intentions to drop out of youth sport. Little is known regarding whether these processes hold across countries. Grounded in SDT, this study tested the invariance of a model predicting youth sport dropout across five European countries. Seven thousand seven hundred and sixty-nine grassroots players (6641 males, 1020 fem…
Promoting Adolescent health through an intervention aimed at improving the quality of their participation in Physical Activity (PAPA): Background to …
2013
International audience; Funded by the European Commission, the Promoting Adolescent health through an intervention is aimed at improving the quality of their participation in Physical Activity (PAPA) project revolved around the potential of youth sport to promote children's mental and emotional health and physical activity engagement. A theoretically grounded coach education training programme (i.e. Empowering CoachingTM), which was designed to create a sporting environment which was more positive and adaptive for young children, was customised for grassroots soccer, delivered and evaluated via a multi-method cluster RCT across five European countries; namely, England, France, Greece, Norwa…
Reviewing 15 years of research on neoliberal conservation: Towards a decolonial, interdisciplinary, intersectional and community-engaged research age…
2021
Abstract In this paper, we undertake an extensive review of the neoliberal conservation literature with the aim to explore and substantiate the principal ways in which conservation is neoliberalized in practice as well as who has studied these processes and through which collaborative patterns. Using descriptive statistics and thematic content analysis, we explore selected characteristics of the peer-reviewed scholarship, including most commonly used concepts, methods and topics, geographical and co-authorship patterns, critical readings of key processes of neoliberalization, including commodification, privatization, dispossession, governance rescaling, governmentalities, and its engagement…
Exploring the contribution of grassroots innovations to justice: using the capability approach to normatively address bottom-up sustainable transitio…
2020
There is growing interest in the potential of grassroots innovations for the transition towards more just and sustainable societies. Nevertheless, there is lack of clear normative discussion regarding these processes. The paper strives to propose and test a framework that enables an analysis of how and in which sense specific grassroots innovation processes may be contributing to the construction of more just societies. To this end, we connect elements of the multi-level perspective on sociotechnical transitions (frequently used in the analysis of grassroots innovations) with elements of the capability approach, which offers a multi-dimensional perspective to justice. The framework is used …
Nanostructural changes in dentine caused by endodontic irrigants
2013
Objective: To study nanostructural dentinal changes produced by endodontic irrigants. Study Design: Experimental study. Nanoindentations were performed on peritubular (PD) and intertubular dentine (ID) with an atomic force microscopy. Stiffness and adhesion force were determined before and after application of 5.25% sodium hypochlorite (NaOCl) and 17% ethylenediaminetetraacetic acid (EDTA). Normalized differences before and after treatment for stiffness and adhesion forces were calculated. A paired T-test was used to compare stiffnes and adhesion force before and after irrigants application. Results: After treatment with EDTA there was a 29.80% reduction in stiffness in ID and a 63.53% redu…
