Trends in land cover and in pollen concentration of Quercus genus in Alentejo, ...
Galveias, Ana; Duarte, Ediclê; Raposo, Mauro; Costa, Maria João; Costa, Ana; Antunes, CéliaMediterranean forests dominated by Quercus species are of great ecological and economic value. The Quercus pollen season, peaking in April, varies in concentration due to geographical and climatic factors and has a remarkable allergenic potential. This study investigates Quercus trends in the Alentejo region of Portugal and examines the influence of meteorological parameters on DPC, PSD and SPIn, as well as the...
Pollen- and Weather-Based Machine Learning Models for Estimating Regional Olive...
Galveias, Ana; Fraga, Helder; Costa, Ana; 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 ...
Congelação com vidragem na conservação de carne de “porco preto”
Rouxinol, Maria Inês; Galveias, Ana; Capelo Soares, Patrícia; Agulheiro-Santos, Ana Cristina; Potes, Maria Eduarda; Laranjo, Marta; Rodrigues, SaraA oxidação das gorduras limita a validade de alimentos congelados. O processo de congelação por vidragem é normalmente utilizado para conservar peixe uma vez que reduz a ocorrência de ranço por oxidação. Estudaram-se dois processos de conservação de carne (secretos) de porco preto: congelação por criogenia (controlo) e congelação por criogenia seguida de vidragem. Realizaram-se as seguintes análises: microbioló...
Estudo do efeito de uma película reciclável na textura, cor e avaliação sensori...
Rouxinol, Maria Inês; Galveias, Ana; Martins, Rita; Capelo Soares, Patrícia; Agulheiro-Santos, Ana Cristina; Potes, Maria Eduarda; Laranjo, MartaA embalagem dos produtos alimentares é essencial para a sua preservação, protecção da influência de factores externos (físicos, químicos, microbiológicos), responsáveis pela qualidade, segurança e higiene dos alimentos. Ao longo dos últimos anos o uso de películas e embalagens biodegradáveis e recicláveis tem vindo a ser estudado devido às suas características não tóxicas e respeito pelo ambiente. Desta forma, ...
Outdoor airborne allergens: Characterization, behavior and monitoring in Europe
Grewling, Lukasz; Ribeiro, Helena; Antunes, Célia; Apangu, Godfrey; Çelenk, Sevcan; Costa, Ana; Eguiluz-Garcia, Ibon; Galveias, Ana; Roldan, NestorAeroallergens or inhalant allergens, are proteins dispersed through the air and have the potential to induce allergic conditions such as rhinitis, conjunctivitis, and asthma. Outdoor aeroallergens are found predominantly in pollen grains and fungal spores, which are allergen carriers. Aeroallergens from pollen and fungi have seasonal emission patterns that correlate with plant pollination and fungal sporulation...
The impacts of land use on the prevalence of allergic sensitization to olive po...
Antunes, Célia; Belchior, Marisa; Galveias, Ana; Rodrigues Costa, AnaAllergic diseases are a serious public health problem mainly in industrialized countries. In Portugal, pollen allergy affects about 20% of the population, with grasses and olive trees being among the most allergenic. The growing increase in the cultivation of olive groves in Alentejo as well as its use as an ornamental plant may have an impact on exposure to allergens, which may influence the risk of sensitizat...
Seasonal particulate matter protein and lipid content: a preliminary study in É...
Custodio, Mariana; Galveias, Ana; Rodrigues Costa, Ana; Costa, Maria João; Antunes, CéliaThe PM existing in the atmosphere, is considered as one of the most harmful pollutants for human health and exposure to PM by inhalation, depending on its variable composition over the different seasons, can cause several inflammatory responses. However, there is little knowledge about the seasonal composition and its impacts on human respiratory health is not yet fully understood. The aim of this preliminary s...

Search for environmental allergens in indoor samples using molecular techniques
Marchã Pennha, Alexandra; Galveias, Ana; Antunes, Célia; Morais, Manuela; Rodrigues Costa, AnaIndoor air quality is one of the most important factors that significantly influence the life quality of the population. Indoor environments are characterized by several sources of pollution, and the health problems associated with bad indoor air quality have acquired high importance in recent years. The biological particles present in the indoor environment can be of various types between viruses and bacteria,...
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...
