Knowledge and regulation on fungal contamination of sand and water: progress re...
Gangneux, Jean-Pierre; Brandão, João; Segal, Ester; Arikan-Akdagli, Sevtap; Barac, Aleksandra; Bertout, Sébastien; Bostanaru, Andra-CristinaFungal flora in coastal/inland beach sand and recreational water is a neglected field of study, despite its potential impact on human health. A joint International Society for Human and Animal Mycology/European Confederation for Medical Mycology (ISHAM/ECMM) working group was formed in 2019 with the task to set up a vast international initiative aimed at studying the fungal contamination of beaches and bathing ...
Flexible visual identity systems in cultural institutions
Figueira, Maria; Raposo, Daniel; Brandão, JoãoThis article aims to contribute to knowledge about the characteristics of a Visual Identity System, including a design exploratory study for the Museu Marítimo de Ílhavo, Portugal. The study focuses on Flexible Visual Identity Systems in the context of cultural organisations, particularly museums. The methodology includes non-interventionist components such as a literature review, a descriptive case study, dire...
Detection of enteric viruses and SARS-CoV-2 in beach sand
Robalo, A.; Brandão, João; Shibata, T.; Solo-Gabriele, H.; Santos, R.; Monteiro, S.Beach sand harbors a diverse group of microbial organisms that may be of public health concern. Nonetheless, little is known about the presence and distribution of viruses in beach sand. In this study, the first objective was to evaluate the presence of seven viruses (Aichi virus, enterovirus, hepatitis A virus, human adenovirus, norovirus, rotavirus, and severe acute respiratory syndrome coronavirus 2 (SARS-Co...
Impacto das alterações climáticas na saúde ambiental: possíveis efeitos em One ...
Valério, Elisabete; Brandão, João; Rebelo, HelenaO conceito One Health reconhece a interconexão entre pessoas, ani- mais, plantas e ambiente, indicando que a saúde humana está ligada a todos os seres vivos e ao ambiente em geral. Neste contexto, é fácil perceber que são muitos os fatores que podem afetar a saúde humana. Este artigo tem como objetivo apontar alguns fatores com capacidade de causar problemas de saúde ambiental, assim como despertar a consciênci...
Strategies for Monitoring Microbial Life in Beach Sand for Protection of Public...
Brandão, João; Valério, Elisabete; Weiskerger, Chelsea; Veríssimo, Cristina; Sarioglou, Konstantina; Novak Babič, Monika; Solo-Gabriele, Helena M.The 2021 revised guidelines of the World Health Organization recommend monitoring the quality of sand in addition to water at recreational beaches. This review provides background information about the types of beaches, the characteristics of sand, and the microbiological parameters that should be measured. Analytical approaches are described for quantifying fungi and fecal indicator bacteria from beach sand. T...
Uso da ferramenta Microbial Source Tracking para identificar a origem da contam...
Valério, Elisabete; Brandão, João; Porteiro, Filipe M.; Cardoso, Fernando J.A.P.; Costa, Margarida M.P.Os espaços balneares referem-se a qualquer área costeira, estuarina ou de água doce, onde um número significativo de pessoas realiza atividades recreativas. Dada a sua natureza, estes constituem um habitat favorável para o abrigo, a multiplicação e a disseminação de uma variedade de microrganismos, podendo assim expor os utilizadores a diversos riscos. Em Julho de 2020, após o levantamento das restrições após o...
Health risk posed by direct ingestion of yeasts from polluted river water
Steffen, Heidi Christa; Smith, Katrin; van Deventer, Corné; Weiskerger, Chelsea; Bosch, Caylin; Brandão, João; Wolfaardt, Gideon; Botha, AlfredRiver water is an essential human resource that may be contaminated with hazardous microorganisms. However, the risk of yeast infection through river water exposure is unclear because it is highly dependant on individual susceptibility and has therefore not been well-studied, to date. To evaluate this undefined risk, we analysed the fungal communities in less polluted (LP) and highly polluted (HP) river water, ...
Quasiclassical study of a termolecular reaction: a more detailed description of...
Mogo, César; Brandão, João; Wang, Wenli; Coelho, Daniela; Rio, CarolinaWe present detailed studies of the collisional stabilization of the HO*2 radical in a mixture of hydrogen atoms and oxygen molecules using molecular dynamic studies and accurate potential energy surfaces. Following previous work on this process's global temperature and pressure dependencies, we analyze each collider's role and estimate specific rate constants and their temperature dependence.
Caspian Sea Mycosands: The Variety and Abundance of Medically Important Fungi i...
Moazeni, Maryam; Hedayati, Mohammad Taghi; Haghani, Iman; Abastabar, Mahdi; Jahantigh, Abolfazl Saravani; Kheshteh, Maryam; Nabili, MojtabaSamples from a total of 67 stations, distributed amongst 32 cities along the Caspian Sea coastline, were collected during the summer of 2021 on sunny days. The samples were collected from each station, including both dry/wet sand and shoreline water. The grown samples were primarily analyzed for the macro/microscopic morphologic features of the fungi. Moreover, identification by PCR-RFLP was performed for yeast...
Endotoxin as a Marker for Water Quality
Sattar, Anas A.; Good, Christian R.; Saletes, Margaux; Brandão, João; Jackson, Simon K.Background: Water quality testing is vital to protect human health. Current testing relies mainly on culture-based detection of faecal indicator organisms such as Escherichia coli (E.coli). However, bacterial cultures are a slow process, taking 24-48 h and requiring specialised laboratories and trained personnel. Access to such laboratories is often sparse in developing countries and there are many fatalities d...
