The European project HIALINE (Health Impacts of Airborne Allergen Information N...

Introduction. Exposure to allergens is pivotal in determining sensitization and allergic symptoms in individuals. Pollen grain counts in ambient air have traditionally been assessed to estimate airborne allergen exposure. However, the exact allergen content in ambient air is unknown. HIALINE therefore monitored atmospheric concentrations of Betula, Poaceae and Olea pollen grains and matched their major allergen...

Identification of potential sources of airborne 0lea pollen in the southwest Ib...

Regional scale transport of olive pollen can result in increased nighttime concentrations of this important aeroallergen. This could be particularly important in Mediterranean countries where people can be outdoors during this time due to climate and lifestyle. Such studies are valuable for allergy sufferers and health care professionals because the information can be incorporated into forecasts, the outputs of...

Identification of Potential Sources of Airborne Olea Pollen in the Southwest Ib...

This study aims to determine the potential origin of Olea pollen recorded in Badajoz in the Southwest of the Iberian Peninsula during 2009-2011. This was achieved using a combination of daily average and diurnal (hourly) airborne Olea pollen counts recorded at Badajoz (southwestern Spain) and Évora (southeastern Portugal), an inventory of olive groves in the studied area and air mass trajectory calculations com...

Hialine Project: allergen release from pollen across Europe

ln general it has been observed similar profiles lor airborne pollen and aeroallergens content in the air, being aeroal/ergens more associated to XL Iraction stage. On the olher hand, ii has been delected al/ergenic activity out Irom pol/en season, especiaily in the case 01 M stage. Smaller particles are more exposed to medium-Iong distant transporto Moreover, results have provides strong evidence that similar ...

The European Project HIALINE: Three Years of Monitoring Pollen and Allergens of...

The results in Italy should be compared with those from partners in other counlries. II will be important to confirm some observations during the first and second year of the projecl activity which showed the presence of a different allergenic power in difleren! geographical areas as observed for other types of pollen (Poaceae and Olea). The aim of lhe project was to measure the pollen's capacity to release all...

Synthesis and electrochemical characterization of aPEO-based polymer electrolyte

In this paper the preparation and purification of an amorphous polymer network, poly[oxymethylene-oligo(oxyethylene)], designated as aPEO, are described. The flexible CH2CH2O segments in this host polymer combine appropriate mechanical properties, over a critical temperature range from -20 to 60 ºC, with labile salt-host interactions. The intensity of these interactions is sufficient to permit solubilization of...

THE HIALINE PROJECT: ALLERGEN RELEASE FROM POLLEN ACROSS 10 EUROPEAN COUNTRIES

Exposure to allergens is one of severa1 factors determining sensitization and allergic symptoms in individuals. Exposure to aeroallergens from pollen is assessed by counting allergenic pollen in ambient air. However, proof is lacking that pollen count is representative for allergen exposure. We therefore monitored simultaneously birch, grass and olive pollen counts and their corresponding major pollen allergen...

Measurements of neutrons produced by high-energy muons at the Boulby Undergroun...

We present the first measurements of the muon-induced neutron flux at the Boulby Underground Laboratory. The experiment was carried out with an 0.73 tonne liquid scintillator that also served as an anticoincidence system for the ZEPLIN-II direct dark matter search. The experimental method exploited the delayed coincidences between high-energy muon signals and gamma-rays from radiative neutron capture on hydroge...

Associação de carcinoma papilífero da tireóide e hiperparatireoidismo

OBJETIVO: A ocorrência de carcinoma papilífero da tireóide (CPT) em doentes com hiperparatireoidismo (HPT) suscita dúvidas quanto a ser apenas coincidência ou apresentar relação causal. O objetivo deste trabalho é verificar se a incidência de CPT em diferentes formas de HPT é semelhante entre si e à incidência de CPT em achados de necropsias, assim como em doentes submetidos à tireoidectomia na mesma região. MÉ...
