SAT0374 IL-36A Axis is Modulated in Patients with Primary Sjogren's Syndrome and Implicated in the Regulation of Gamma-Delta T Cells Immune Functions
2015
Background IL-36a is a cytokine that predominantly acts on naive CD4+ T cells and gamma-delta T cells via the IL-36 receptor. IL-36a has been recently demonstrated to be involved in human disease, such as psoriasis, by modulating innate and adaptive immune responses. Objectives In this study we aimed to investigate the expression of IL-36 axis and to assess the role of γδ T cells in patients with primary Sjogren9s syndrome (pSS). Methods Blood and minor labial salivary glands (MSG) biopsies were obtained from 35 pSS and 20 nSS patients. Serum IL-36a was assayed by ELISA. IL-36a, IL-36R, IL-36RA, IL-38, IL-22, IL-17, IL-23p19, expression in MSGs was assessed by rt-PCR and tissue IL-36a and I…
Melampsora allii-fragilis f. sp. galanthi-fragilis reported for first time to cause rust on Galanthus plicatus in Latvia
2010
In Europe, Melampsora allii-fragilis f. sp. galanthi-fragilis (syn. Melampsora galanthi-fragilis) has been reported on leaves of snowdrop (Galanthus nivalis) in Romania (Savulescu, 1953; Bagyanarayana, 2005) and on Galanthus plicatus in Ukraine (Gutsevich, 1952). The GBIF Database has additional records of this fungus on G. nivalis from Austria, Czech Republic and France but the USDA SMML Specimens Database has also records from Hungary and Poland. According to this database, the established distribution area of M. allii-fragilis f. sp. galanthi-fragilis is ‘Central Europe’. Melampsora allii-fragilis f. sp. galanthi-fragilis belongs to the heteroecious rust fungi that require two hosts to c…
Solving Non-Stationary Bandit Problems by Random Sampling from Sibling Kalman Filters
2010
Published version of an article from Lecture Notes in Computer Science. Also available at SpringerLink: http://dx.doi.org/10.1007/978-3-642-13033-5_21 The multi-armed bandit problem is a classical optimization problem where an agent sequentially pulls one of multiple arms attached to a gambling machine, with each pull resulting in a random reward. The reward distributions are unknown, and thus, one must balance between exploiting existing knowledge about the arms, and obtaining new information. Dynamically changing (non-stationary) bandit problems are particularly challenging because each change of the reward distributions may progressively degrade the performance of any fixed strategy. Alt…
Thompson Sampling Guided Stochastic Searching on the Line for Adversarial Learning
2015
The multi-armed bandit problem has been studied for decades. In brief, a gambler repeatedly pulls one out of N slot machine arms, randomly receiving a reward or a penalty from each pull. The aim of the gambler is to maximize the expected number of rewards received, when the probabilities of receiving rewards are unknown. Thus, the gambler must, as quickly as possible, identify the arm with the largest probability of producing rewards, compactly capturing the exploration-exploitation dilemma in reinforcement learning. In this paper we introduce a particular challenging variant of the multi-armed bandit problem, inspired by the so-called N-Door Puzzle. In this variant, the gambler is only tol…
The use of constructed wetlands for the treatment and reuse of urban wastewater for the irrigation of two warm-season turfgrass species under Mediter…
2017
Constructed wetlands (CWs) represent low-cost technology for the treatment and reuse of wastewater in urban areas. This study aimed to evaluate the pollutant removal efficiency of a CW system and to assess the effects of irrigation using treated urban wastewater on soil and on two warm-season turf species. The research was carried out in Sicily (Italy) on a pilot-scale horizontal subsurface flow system which was fed with treated urban wastewater following secondary treatment from an activated-sludge wastewater treatment plant. The pilot system was located in an open urban park and comprised two separate parallel planted units. Experimental fields of Cynodon dactylon (L.) Pers. and Paspalum …
A la nación por la clase. La campaña electoral socialista de noviembre de 1933
2017
El artículo analiza la campaña electoral realizada por el Partido Socialista Obrero Español para las elecciones de noviembre del 1933. A partir de la importancia que la nueva historia sociocultural y política atribuye a los discursos en la conformación de las identidades y la acción colectiva, el artículo intenta poner de manifiesto la capital importancia que tuvo el uso de la narrativa nacional por parte del socialismo. Con ello, se trata de llamar la atención sobre una vía central en la (re)construcción y difusión social de la identidad nacional española, como los procesos de politización y el rol que el socialismo pudo jugar a tal efecto. The article deals with electoral campaign carried…
Prophenoloxidase activating system in tunicate hemolymph
1996
The activation sequence and related factors of the prophenoloxidase activating system in crustaceans was compared with the equivalent system in tunicates. Both solitary and colonial ascidians present in their hemolymph a copper-dependent phenoloxidase activity that may be inhibited by tropolone and phenylthiourea. Carbohydrates are able, to various extents, to trigger proPO system which requires serine protease cleavage for activation to phenoloxidase (PO). In some ascidians, hemocytes called ≪morula cells≫ show PO activity, while in Ciona intestinalis the ≪univacuolar refractile granulocytes≫ are positive after cytochemical staining with L-dopa. The relationships between proPO system and d…
SOILS WITH HIGH ORGANIC CARBON STORAGE CAPACITY IN DEPTH
2012
Most studies about soil organic carbon (OC) stock focus on the topsoil storage capacity, however, it has been proved that OC can reach relatively high values also in depth. The aim of this work was a preliminary investigation of the soil types with a high OC content in depth and the relationship with the main pedogenetic factors. The dataset was the 1,414 Italian National Soil Typologies (STU). The selected attributes were: mean value of OC in the superficial functional horizon (L1); weighted average value between 50 and 100 cm (L2) and under 100 cm (L3); WRB classification; main lithology, morphology and land-use. About 92% of typologies had more than 0.58% of OC in L1, about 30% in L2, an…
Anthropomorphic wooden reliquaries an integrated approach to restoration
2015
Two wood anthropomorphic reliquaries, belonging to Lipsanoteca of Epiphany Church, Trapani (Italy), were restored following procedures based on an interdisciplinary approach. The historic-artistic contextualization, constitutive materials and executive techniques were defined. Degradation events were correlated to physical-chemical factors, with particular attention to biodeteriogens. Insect infestation was revealed, by optical (OM) and scanning electron microscopy (SEM) of rosume and insect body remains, Anobium punctatum was identified. Microbial colonization was revealed and characterized by an integrated approach based on OM (Lugol’s staining), in vitro culture and molecular investigati…
ANTHROPOMORPHIC WOODEN RELIQUARIES FROM KNOWLEDGE TO RESTORATIOI{
2014
Two wood anthropomorphic reliquaries, belonging to the Lipsanoteca of Epiphany Church in Trapani (Ita1y) were restored following the consewative restoration procedures based on an interdisciplinary approach. The hystoric-artistic contextualization, the constitutive rnaterials and executive techniques were defined and physical-chemical-biological factors involved in degradation events were evaluated. The Saints relic (human bone or teeth), present in each reliquary were analysed through visual investigation. After restoration, the manufacts showed their peculiarities and their extraordinary cultural value.
