Elevated levels of anti-endotoxin antibodies in patients with bilateral idiopathic acute anterior uveitis
2010
. Purpose: Endotoxins have been proved to be responsible for acute anterior uveitis (AAU) in animals in a well-established experimental model of endotoxin-induced uveitis (EIU). The purpose of our study was the detection of antibodies against endotoxins of selected enterobacteria in the serum of patients with idiopathic AAU and searching for correlations between the levels of these antibodies and the presence of HLA-B27 antigen as well as characteristic signs of EIU such as bilaterality and the absence of spontaneous recurrences of the disease. Methods: Reactions of serum IgG antibodies with lipopolysaccharides (LPSs) of Escherichia coli O1, E. coli O10, E. coli O111, E. coli J5, and Kleb…
klebsiella pneumoniae-reactive t cells in blood and synovial fluid of patients with ankylosing spondylitis comparison with hla–b27 + healthy control …
1995
Objective To study the frequency of Klebsiella pneumoniae-responsive T cells in the peripheral blood (PB) of ankylosing spondylitis (AS) patients compared with that in healthy HLA-B27+ donors, and to examine T lymphocyte clones (TLC) derived from AS patient synovial fluid (SF) for the presence of Klebsiella reactivity. Methods Limiting dilution analysis of PB T cells in 8 patients with active AS and in 8 HLA-B27+ healthy subjects was used to determine the frequency of PB T cells responsive to K pneumoniae and Escherichia coli GroEL. SF T cells from a patient with active AS were cloned, and 125 TLC were characterized in proliferation assays. Results There were fewer T cells in the PB of AS p…
Ankylosing spondylitis in monozygotic twins: studies on immunological parameters
1999
OBJECTIVE—To examine immunological parameters that might explain disease discordance in monozygotic twin pairs with ankylosing spondylitis (AS). METHODS—11 monozygotic twin pairs (nine with AS, two with undifferentiated spondyloarthropathy) were investigated. The peripheral T cell receptor Vβ repertoire was investigated using FACS analysis and 14 different Vβ antibodies. In addition serum samples were tested for antibodies to Klebsiella pneumoniae, Streptococcus pyogenes, Candida albicans, Proteus mirabilis, and Escherichia coli. Peripheral blood lymphocyte reactivity against a number of bacteria was investigated by interferon γ ELISPOT assays. RESULTS—Twins suffering from AS showed cellula…
Assessment of Anthropogenic Ecological Systems in the Apold Depression to a Sustainable Management
2015
The vast majority of households in Ethiopia live in rural areas and agriculture is still the main economic activity. They rarely produce for the market and are highly dependent on climate for their subsistence. In this paper, the market options available to these farmers, as well as market related factors that are problematic were investigated. Multi-stage sampling procedure was employed to draw sample of 150 teff producers. Double hurdle model was used to identify factors affecting market participation and intensity of marketed surplus of teff. Market participation of smallholder farmers was significantly affected by access to credit, perception of farmers on lagged market price of teff, f…
Spatial and temporal distribution of ooids along a Jurassic carbonate ramp: Amellago outcrop transect, High-Atlas, Morocco
2010
Carbonate ramp systems are widespread throughout the geological record, but very few areas have seismic-scale, continuous and structurally undeformed outcrops that allow reliable interpretation of facies distributions and stacking patterns. The Amellago outcrop shows the detailed depositional and stratigraphic relationships of an ooid-dominated ramp system that is almost completely exposed along a dip profile (37 km long and 1000 m thick) in the Lower to Middle Jurassic of the southern High Atlas, Morocco. Ammonite and brachiopod fauna provide excellent biostratigraphic control on small scale stacking patterns. At Amellago, the evolution of depositional environments is evident at different …
Implementation of IFRS in Japan: An Analysis of Voluntary Adoption by Listed Firms
2019
Since 2010 Japanese listed firms can voluntarily use international financial reporting standards for their consolidated financial statements. Using financial and non-financial data, we carry out a comprehensive research into the adopters’ determinants. We employ a multi-period logit model that considers every annual decision made along the period 2010-2019. We find that the having outside networks through subsidiaries and a strong internal corporate governance system are key factors. We also confirm a contagion effect. Finally, our results suggest that goodwill is also relevant, since only Japanese accounting standards require annual amortization.
The Financing of Education : An Economic Issue ?
2000
Building on previous contributions on the same topic, this article gives a brief overview of the financial situation of Education in the different regions of the world then focuses on the shortcomings of the traditional treatment of financing issues by economist among them the quasi absence of equity consideration. It ends by discussing the main issues as they can be seen today : extent of the "right to education", demand side approach to education financing, choice between various types of subsides to students.
Neanderthal subsistence and short-term human occupation patterns during MIS 5. New data from Abrigo de la Quebrada (Valencia, Spain)
2019
Abstract Abrigo de la Quebrada (Chelva, Valencia) is a Middle Palaeolithic site with Neanderthal occupations, composed by nine archaeological levels that extend from MIS 3–5 in the upper levels (II-V), up to MIS 5 in the lower levels (VI-IX), with dates for level VI of 80.0 ± 4.7 ky and 83.2 ± 5.4 ka. Level IV show short and repeated human occupations, with a high density of materials related to hunting activities focus on several ungulates as ibex, equids and cervids. However, the lower levels (VII, VIII and IX) respond to different sedimentation rates and occupations. Archaeozoological and taphonomic studies show mixed occupations. Raptors or small carnivores seem to be responsible of the…
La Cuevona de Avín (Avín, Asturias, North Spain): A new Late Pleistocene site in the lower valley of the River Güeña
2022
The archaeological investigations carried out in the last twenty years in the Lower Valley of the River Güeña (Asturias, central part of northern Spain) have documented different prehistoric sites, particularly with Middle and Upper Palaeolithic occupations. This paper presents the results of the archaeological excavation carried out in the cave of La Cuevona de Avín. From the systematic study of the biotic and abiotic remains, a total of three occupation phases (Phases 1 to 3) have been determined, dated in the Late Pleistocene. The lithic studies indicate the use of local raw materials (mainly quartzite), but also regional ones (different types of flint) in the whole sequence. Retouched i…
Lifestyle, occupation, and whole bone morphology of the pre-Hispanic Maya coastal population from Xcambó, Yucatan, Mexico
2007
The present bioarchaeological study examines the external diaphyseal geometric properties of humeri, radii, femora and tibiae of the Classic period skeletal population of Xcambo, Yucatan, Mexico. The diaphysial proportions are evaluated using a biomechanical approach together with data from the material context and other osteological information. Our intent is to provide new answers to questions concerning lifestyle, domestic labour division and subsistence strategies of this coastal Maya settlement that was inhabited from the Late and Terminal Preclassic (300 BC–350 AD) to the Postclassic Period (900–1500 AD). Our results provide evidence for a marked sexual division of labour when compare…
