Memoria oral y alimentación: estrategias de supervivencia durante la Guerra Civil Española (1936-1939) y la posguerra (1939-1955)
2011
El principal objetivo de nuestro tra bajo es delimitar las prácticas de reciprocidad que se llevaron a cabo durante el período de tiempo analizado y que permitieron reproducirse socialmente a los grupos menos favorecidos por la guerra y la posguerra . Nuestro análisis demuestra que la alimentación es un sistema de comuni - cación mediante el cual se crean o mantienen prácticas de poder , así como expre - siones de identidad y/o defensa o ruptura de las normas morales que comparte un grupo social .
EAACI Position paper on the standardization of nasal allergen challenges.

DR. FARID, S.H. M.H. M. Kn. - FR FARID/0000-0003-0372-4963; Gevaert, Philippe/0000-0002-1629-8468; Hox, Valerie/0000-0003-2390-294X; Wagenman, Martin/0000-0002-9734-0241; Vent, Julia/0000-0001-5071-9580 WOS: 000438710600002 PubMed: 29377177 Nasal allergen challenge (NAC) is an important tool to diagnose allergic rhinitis. In daily clinical routine, experimentally, or when measuring therapeutic success clinically, nasal allergen challenge is fundamental. It is further one of the key diagnostic tools when initiating specific allergen immunotherapy. So far, national recommendations offered guidance on its execution; however, international divergence left many questions unanswered. These differ…
Short-term preseasonal birch pollen allergoid immunotherapy influences symptoms, specific nasal provocation and cytokine levels in nasal secretions, …
1999
Backround Birch pollen allergic rhinitis can be sufficiently treated with specific subcutaneous allergoid immunotherapy (IT). However, little is known about the clinical and immunological effects of short-term therapy protocols. Objective To investigate the clinical efficacy of a birch pollen allergoid IT using seven preseasonal injections and to evaluate immunological parameters that might explain clinical findings. Methods Thirty-seven patients were included into the study and randomized to either a symptomatic treatment or allergoid IT plus symptomatic treatment. Patients were examined during the pre-IT season, at two extraseasonal visits both before and after IT and during the post-IT s…
Nasal IgE in subjects with allergic and non-allergic rhinitis
2020
Abstract Purpose The prevalence of "ocal allergic rhinitis" within individuals suffering from perennial rhinitis remains uncertain, and patients usually are diagnosed with non-allergic rhinitis. The aim of this study was to evaluate the prevalence of a potential "local allergic rhinitis" in subjects suffering from non-allergic rhinitis in a non-selected group of young students. Methods 131 students (age 25.0 ± 5.1 years) with a possible allergic rhinitis and 25 non-allergic controls without rhinitis symptoms (age 22.0 ± 2.0 years) were recruited by public postings. 97 of 131 students with rhinitis were tested positive (≥3 mm) to prick testing with 17 frequent allergens at visit 1. Twenty-fo…
Airways Hyperresponsiveness and the Effects of Lung Inflation
2001
Lung inflation has a beneficial effect on the airways of healthy subjects. It acts as a bronchoprotector, that is to prevent bronchoconstriction, and as a bronchodilator, in that it reverses bronchial obstruction. The bronchoprotective effect of deep inspiration is more potent than the bronchodilatory one, and the two phenomena appear to advocte different mechanisms. Asthmatics and rhinitics with airways hyperresponsiveness show an impairment in bronchoprotection induced by deep breaths, whereas the bronchodilatory effect, although reduced, is still effective. The lack of the bronchoprotective effect of deep inspiration may contribute to the development of airways hyperresponsiveness. The m…
A Multicenter Trial of Specific Local Nasal Immunotherapy
2000
Objective: To assess the efficacy and safety of specific local nasal immunotherapy (LNIT) in powder form in patients with allergic rhinitis, using subjective and objective parameters. Study Design: A double-blind randomized multicenter trial of 102 patients with allergic rhinitis who were treated with specific LNIT for 8 consecutive months. Methods: After identifying allergens with the skin prick test and sensitization threshold dose with the specific nasal provocation test, 102 patients were selected, of whom 55 were allergic to mites and 47 were allergic to Graminaceae or Parietaria pollen. The specific treatments were self-administered using an insufflator in two phases (phase 1: increas…
Defects in yttrium aluminium perovskite and garnet crystals: atomistic study
2000
Native and impurity point defects in both yttrium aluminium perovskite (YAP) and garnet (YAG) crystals are studied in the framework of the pair-potential approximation coupled with the shell model description of the lattice ions. The calculated formation energies for native defects suggest that the antisite disorder is preferred over the Frenkel and Schottky-like disorder in both YAP and YAG. The calculated values of the distortion caused by the antisite YAl x in the lattice turn out to be in an excellent agreement with the EXAFS measurements. In non-stoichiometric compounds, the calculated reaction energies indicate that excess Y2 O3 or Al2 O3 is most likely to be accommodated by the forma…
A rietveld study of the cation substitution between uvarovite and yttrium-aluminum synthetic garnets, obtained by sol-gel method
1994
A series of synthetic garnets solid solutions with compositions between Y 3 Al 2 Al 3 O 12 (Y-Al garnet) (YAG) and Ca 3 Cr 2 Si 3 O 12 (uvarovite) was synthesized using the sol-gel method. The expected general formula is (Ca x Y 1-x ) 3 (Cr x Al 1-x ) 2 (Si x Al 1-x ) 3 O 12 where x=0 to x=1. The cation distribution in dodecahedral, octahedral and tetrahedral sites and bond distances in these synthetic garnets were determined using the Rietveld method. It shows the incomplete substitution in small sites. The smaller site the smaller substitution there is
Inuentiones y translationes de S. Mercurio
2019
Inuentiones and translationes of the relics are part of the hagiographic dossier of a saint and provide interesting information about his cult over the centuries. For S. Mercurius of Caesarea the original texts in Greek have been lost, but we have two collections miracles in Coptic that narrate the inuentio and translatio of his relics and there is also a medieval tradition about his translatio to Benevento (Italy). From all these texts is deduced a healing cult of S. Mercurius based on the usual topics.
First record of the enigmatic coleoid genus Longibelus from Sakhalin (Far East Russia): a contribution to our understanding of Cretaceous coleoid hab…
2021
AbstractA newly collected specimen of the enigmatic coleoid genus Longibelus is recorded from lower Turonian strata along the River Shadrinka in Sakhalin (Russian Far East). To date, this is the first record of Late Cretaceous coleoid cephalopods from the island and, in fact, from the entire Pacific coast of the Russian Federation. Lithological characteristics, coupled with published geochemical analyses (δ13C and Corg content), suggest the habitat of this coleoid taxon to have been the middle to outer (i.e. distal) shelf. Its provenance from the stratigraphical level that is known as the Scaphites Event, characterised by a mass occurrence of Scaphites and Yesoites, may be indicative of occ…
