Differential Quercus spp pollen-particulate matter interaction is dependent on ...
Galveias, Ana; Ribeiro, Helena; Guimarães, Fernanda; Costa, Maria João; Rodrigues, Pedro; R Costa, Ana; Abreu, Ilda; M Antunes, CéliaParticulate matter (PM) and pollen interaction, either airborne or at the respiratory mucosa needs further clarification, as allergic reaction intensification can be related to the PM physical characteristics and toxicity. This study aimed to investigate the physical-chemical properties of PM that can adhere to the pollen wall during its transport or inhalation, using Quercus spp. as a model, in three Portugues...
Cupressaceae Pollen in the City of Évora, South of Portugal: Disruption of the ...
Galveias, Ana; R Costa, Ana; Bortoli, Daniele; Alpizar-Jara, Russell; Salgado, Rui; Costa, Maria João; M Antunes, CéliaResearch Highlights: Daily airborne Cupressaceae pollen disruption ranged from 20 to 90%; relative humidity (RH), rainfall and atmospheric pressure (AtP) were the major meteorological determinants of this phenomenon. Background and Objectives: Cupressaceae family includes several species that are widely used as ornamental plants pollinating in late winter-early spring and might be responsible for allergic outbr...
Air pollutants NO2- and O3-induced Dactylis glomerata L. pollen oxidative defen...
Galveias, Ana; Arriegas, Rute; Mendes, Sara; Ribeiro, Helena; Abreu, Ilda; R Costa, Ana; M Antunes, CéliaAir pollutants impact airborne pollen biochemistry. Oxidative damage to lipids, proteins and nucleic acids or protein nitration are among ozone (O3) and nitrogen dioxide (NO2) described deleterious effects possibly causing pollen physiology damage and enhanced allergenic activity, contributing to aggravate pollen driven respiratory allergy in urban areas. The goal of this research was to evaluate the effects of...
The inventory of the pollen monitoring networks worldwide: results of the TF-40...
M Antunes, Célia; Galveias, Ana; Oteros, J; Galan, Carmen; Werchan, M; Thibaudon, M; Buters, Jntroduction:It is expected that about 600 stations for pollen andother biological particles in ambient air exist worldwide (Buters2014). However, currently no comprehensive information on pollenmonitoring sites is available as the map in the“Atlas of allergy”(Buters 2014) is already outdated and/or incomplete. In fact, in manycases no information, limited information, or false information onwho, where, what and...
Q. rotundifolia and p. hybrida pollenextracts induced basophil degranulation: s...
M Antunes, CéliaIntroduction:Currently skin prick test remains the favorite tech-nology in allergy diagnosis to aeroallergens. These tests, however,cause discomfort to the patient. Several biochemical methods basedon IgE analysis are available but have limited diagnostic power asbiological response, hence elicitation of allergic reaction, is not pre-dicted by these tests.Objectives:The aim of this work was to investigate wheth...
Allergy medications sales: An usefulsurrogate marker for pollinosis health impa...
Rodrigues Costa, Ana; Arriegas, Rute; Afonso, Anabela; Galveias, Ana; C Silva, Joaquim; M Antunes, Céliantroduction:The burden of pollen allergies has been increasingworldwide. Due to their environmental-related aetiology, manage-ment of the disease in a changing environment has proven challeng-ing. Several strategies have been used aiming the monitoring of thedisease health impacts with limited outcomes.Objectives:The aim of this work was to investigate the associationbetween the sale of antiallergic drugs with ...
