Lack of linkage between gene(s) controlling the synthesis of the seventh component of complement and the HLA region on chromosome No. 6 in man.
1976
The family of an individual was studied who lacks the seventh component of complement in his serum (C7 homozygous deficiency). Both parents are C7 heterozygousdeficient. In this investigation, the following parameters were determined: complement components in functional and immunochemical tests; HLA-A,B antigens, HLA-D (MLC) determinants; the Bf system; glyoxalase I and B cell antigens. No evidence for linkage between the immunogenetic linkage group on chromosome 6 and gene(s) controlling the synthesis of the seventh component of complement was obtained. This is in accordance with the assumption that only genes controlling components of the initiating rather than the membrane attack unit of…
Skills for competitiveness: an empirical analysis of the educational provision for oenologists offered by Italian universities
2022
Purpose: Whilst operating in the context of a high-income economy, the Italian labour market is affected by the considerable challenges of vertical mismatch, skill gaps and skill shortages. In such a context, the aim of this empirical study is to explore current university provision regarding the formal qualification of the oenologist, in order to assess its alignment with the professionalism demands from the wine sector. Design/Methodology/Approach: The following was deployed to analyse university provision with a mixed method approach including social network analysis, cluster analysis and desk analyses based on descriptive statistics. Findings: The comparative analysis outlined in the re…
A coordinated preventive care approach for healthy ageing in five European cities: A mixed methods study of process evaluation components
2019
To evaluate specific process components of the Urban Health Centres Europe (UHCE) approach; a coordinated preventive care approach aimed at healthy ageing by decreasing falls, polypharmacy, loneliness and frailty among older persons in community settings of five cities in the United Kingdom, Greece, Croatia, the Netherlands and Spain.Mixed methods evaluation of specific process components of the UHCE approach: reach of the target population, dose of the intervention actually delivered and received by participants and satisfaction and experience of main stakeholders involved in the approach.The UHCE approach intervention consisted of a preventive assessment, shared decision-making on a care …
Using concept mapping in the development of the EU-PAD framework (EUropean-Physical Activity Determinants across the life course): a DEDIPAC-study
2016
International audience; Background: A large proportion of European children, adults and older adults do not engage in sufficient physical activity ( PA). Understanding individual and contextual factors associated with PA behaviours is essential for the identification and implementation of effective preventative environments, policies, and programmes that can promote an active lifestyle across life course and can potentially improve health. The current paper intends to provide 1) a multi-disciplinary, Pan-European and life course view of key determinants of PA behaviours and 2) a proposal of how these factors may cluster. Methods: After gathering a list of 183 potential PA behaviours-associa…
Impact of the COVID-19 lockdown on a long-term care facility: the role of social contact
2021
Background: Long-term care facilities (LTCFs) have been harmed by the coronavirus, and older adults have remained isolated for a long time with many restrictions. The aim of this study was to measure the decline in cognitive, functional, and affective status in a care facility after the lockdown in the first wave of the COVID-19 pandemic and to compare it with previous measures in order to determine if this decline was accelerated. (2) Methods: Ninety-eight participants were recruited. Data from three retrospective pre-lockdown assessments and an additional postlockdown assessment were analyzed. Mixed ANOVA analyses were performed according to the Clinical Dementia Rating levels, considerin…
Coupling Lagrangian simulation models and remote sensing to explore the environmental effect on larval growth rate: The Mediterranean case study of r…
2023
The relationship between environmental conditions and early life-history traits of Sardinella aurita are investigated using material collected in two sites of the Central Mediterranean Sea. Individual mean daily growth during the planktonic phase has been determined by using otolith microstructure analysis, while Lagrangian simulation models allowed to estimate the daily position in space and time of each specimen from the hatching to the catch. Generalized Additive Mixed Models (GAMMs) have been implemented to explore the impact of environmental conditions at time t, t-1 day and t-2 days on the mean daily growth rate occurring at time t. Spatial analysis evidenced a wide dispersion of eggs…
Apparent transinhibition of peptide uptake in the scutellum of barley grain
1985
The uptake of glycylsarcosine (Gly‐Sar) into scutella separated from germinating grains of barley (Hordeum vulgare L. cv. Himalaya) is inhibited by other peptides; in most cases the inhibition is not purely competitive but of a mixed type (simultaneous increase in the apparent Km and decrease in Vmax) (Sopanen, T. 1979. FEBS Lett. 108: 447–450). The aim of the present experiments was to elucidate the mechanism of the mixed inhibition by studying how peptides already taken up into the cells affect the uptake of Gly‐Sar. When scutella were preincubated in the presence of various peptides, 11 of the 13 peptides tested inhibited the subsequent uptake of Gly‐Sar by 10 to 45%. The inhibition, stu…
Fusion of visual tools in virtual spaces
1996
Virtual space environment may be improved by combining it with graphical and visual tools. This paper analyses an integrated system able to merge fusion techniques, icons tools and a virtual space environment. A virtual space is characterised by a set of dynamic visual icons and by a heterogeneous virtual reality environment. Their integration is supported by virtual icon grammar (VIG) working on dynamic icons and virtual world. VIG allows to test the actions made by dynamic icons on the activated Virtual World metaphors at a time “t”, and a range of different transactions that place between user and VW(visual query, view and browse of under-world,...), moreover, user can define, modify and…
Variable selection in mixed models: a graphical approach
2014
Model selection can be defined as the task of estimating the performance of dif- ferent models in order to choose the (approximate) best one. The purpose of this article is to introduce an extension of the graphical representation of deviance proposed in the framework of classical and generalized linear models to the wider class of mixed models. The proposed plot is useful in determining which are the important explanatory variables conditioning on the random effects part. The applicability and the easy interpretation of the graph are illus- trated with a real data examples.
Quasihyperbolic boundary condition: Compactness of the inner boundary
2011
We prove that if a metric space satisfies a suitable growth condition in the quasihyperbolic metric and the Gehring–Hayman theorem in the original metric, then the inner boundary of the space is homeomorphic to the Gromov boundary. Thus, the inner boundary is compact. peerReviewed
