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...
Differences in salivary α-amylase levels among women ith different taste sensit...
Sequeira, Márcia; Rodrigues, Lénia; R Costa, Ana; Antunes, Célia; Pinheiro, Cristina; Lamy, ElsaSaliva is the main component of taste receptor cells external environment, and consequently it may have a decisive role in taste perception. Taste sensitivity varies among different individuals. Sensitivity to the compound n-6-propylthiouracil (PROP) has been considerably studied and besides the known influence of genetic background, the contribution of perireceptor environment is not completely clear yet. Sali...
