Pollen- and Weather-Based Machine Learning Models for Estimating Regional Olive...
Galveias, Ana \; Fraga, Helder; Costa, Ana Rodrigues; Antunes, Célia M.The olive tree is one of the most common type of cultivation in the Mediterranean area, having high economic and social importance. The Alentejo region, Portugal, is an area with a high presence of olive groves, which in 2022 accounted for 201,474 hectares. The aim of this study was to assess the relationship between olive pollen, weather data, and olive tree production, between the years 2002 and 2022. Pollen ...

Atmospheric pollen allergen load and environmental patterns in central and sout...
Lara, Beatriz; Rojo, Jesús; Costa, Ana R.Costa; Burgos-Montero, Ana M.; Antunes, Célia M.Over one quarter of the population in industrialised countries suffers from some type of allergy and inhaled aeroallergens from pollen are the primary cause of allergic ailments. The networks for monitoring biological air quality measure the airborne pollen concentrations that characterize periods of exposure to major airborne aeroallergens but there are certain discrepancies in relation to the allergen-pollen ...
Automatic detection of airborne pollen: an overview
Buters, Jeroen; Clot, Bernard; Gehrig, Regula; Gilge, Stefan; Hentges, François; O’Connor, David; Sikoparija, Branko; Skjoth, Carsten; Tummon, FionaPollen monitoring has traditionally been carried out using manual methods first developed in the early 1950s. Although this technique has been recently standardised, it suffers from several drawbacks, notably data usually only being available with a delay of 3–9 days and usually delivered at a daily resolution. Several automatic instruments have come on to the market over the past few years, with more new devic...
XXI SPB CONGRESS BOOK
Antunes, Célia M.; Costa, Ana R.; Palma, Patrícia; Gastalho, Carlos; Marques, Mariana; Galveias, Ana; Cancela, Leonor; Aureliano, ManuelThe University of Évora welcomes YOU at the XXI SPB National Congress of Biochemistry 2020 in 14-16 October 2021 either in person or online! Under challenging conditions, due to the COVID-19 pandemic, we have managed to organize the National Congress of Biochemistry in a hybrid format, where at least 2/3 of the participants will come to Évora in person. With the pandemic under control and we hope to carry out t...
Cupressaceae Pollen in the City of Évora, South of Portugal: Disruption of the ...
Galveias, Ana; Costa, Ana R.; Bortoli, Daniele; Alpizar-Jara, Russell; Salgado, Rui; Costa, Maria João; Antunes, Célia M.Research 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...
Salsola Kali sensitization and cross-reactivity with Olea Europea in patients w...
Burgos-Montero, Ana; Costa, Ana R.; Galveias, Ana; Lara, Beatriz; Gonzalez-Sanchez, Luís A.; Antunes, Célia M.; Feo Brito, Francisco; Perez-Badia, RosaBackground : The Allergy Department of Alcázar de San Juan, in the Mancha Centro Hospital (ASJ- MCH), Ciudad- Real, Spain, attends patients with respiratory allergy to pollen of different species, such as Salsola kali . Patients mono- sensitive have symptoms in late sum-mer, in the pollination time of Salsola , but also in spring, when there is pollination time of other species such as Olea europaea . It is de-...
Sensitization to holm oak and plane tree pollen and cross- reactivity patterns ...
Antunes, Célia M.; Calhau, Isabel; Marques, D.; Silva, C.; Galveias, Ana; Arriegas, Rute; Martins, Luís; Fernandes, M.; Costa, Ana R.Background: Plane (Platanus hybrida) and holm oak (Quercus rotun-difolia) trees pollen are among the most prevalent in Alentejo with pollination peaks in the early spring (March and April). Despite the high level of exposure of the population, these pollen types are considered moderately allergenic and both the sensitization and their allergen profiles are yet poorly characterized in this region. In this work, ...
Effects of hyperleptinemia in rat saliva composition, histology and ultrastruct...
Lamy, Elsa; Neves, S; Ferreira, J; Rodrigues, Lénia; da Costa, G; Cordeiro, C; Fialho, Luisa; Lima, Mónica; Costa, Ana R.; Antunes, Célia M.OBJECTIVE: To study the effect of the satiety hormone, leptin, in saliva proteome and salivary gland histology and ultrastructure. DESIGN: Increases in blood leptin levels were induced through mini-pump infusion in male Wistar rats, during a period of 7 days. Saliva was collected before and at the end of the experimental period, for proteomic analysis, and major salivary glands were collected, at the end, for b...
Application of the adverse outcome pathway (AOP) concept to structure the avail...
van Bilsen, Jolanda H. M.; Sienkiewicz‑Szłapka, Edyta; Lozano‑Ojalvo, Daniel; Willemsen, Linette E. M.; Antunes, Célia M.; Molina, HelenaBackground: The introduction of whole new foods in a population may lead to sensitization and food allergy. This constitutes a potential public health problem and a challenge to risk assessors and managers as the existing understanding of the pathophysiological processes and the currently available biological tools for prediction of the risk for food allergy development and the severity of the reaction are not ...
