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 impact of noise exposure in Air Force Military
Correia, Mariana; Matos, Teresa; Ribeiro, Helena; Lopes, Marina; Almada, SofiaIntroduction: Military aviation is characterized by multiple noise sources, which are worrying as they exceed the legal limits required. The objective of this study is to evaluate the need to extend the monitoring program for all military exposed to aviation noise in the Air Force Units, with the specific objectives of evaluating the noise level to which they are exposed during the day and assessing the impact ...
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...
New insights into the dermocosmetic potential of the red seaweed Gelidium corneum
Matias, Margarida; Martins, Alice; Alves, Celso; Silva, Joana; Pinteus, Susete; Fitas, Manuel; Pinto, Pedro; Marto, Joana; Ribeiro, HelenaThis work addresses the potential of the red seaweed Gelidium corneum as a source of bioactive ingredients for skin health and wellness in response to the growing awareness regarding the significance of sustainable strategies in developing new nature-based dermocosmetic products. Hydroalcoholic extracts from the dried biomass were subjected to sequential liquid–liquid partitions, affording five different fracti...
Design and Characterization of an Ethosomal Gel Encapsulating Rosehip Extract
Sallustio, Valentina; Farruggia, Giovanna; Di Cagno, Massimiliano Pio; Tzanova, Martina M.; Marto, Joana; Ribeiro, Helena; Gonçalves, LídiaRising environmental awareness drives green consumers to purchase sustainable cosmetics based on natural bioactive compounds. The aim of this study was to deliver Rosa canina L. extract as a botanical ingredient in an anti-aging gel using an eco-friendly approach. Rosehip extract was first characterized in terms of its antioxidant activity through a DPPH assay and ROS reduction test and then encapsulated in eth...

Ribeiro, Helena; Mabunda, Lígia; Freitas, Sílvia; Sitoe, Ana Raquel; Bettencourt, AnaThe National Medicines Regulatory Authority, I.P (ANARME, I.P) of Mozambique created several mechanisms to ensure the quality, safety and performance of medical devices (MDs) with the publication of the Ministerial Dispatch of January 13th, 2017. However, one of the main shortcomings of the current regulatory system is the fact that it does not cover the entire classification and registration system, in order t...
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...
