Genome-wide association study identifies genetic variants underlying footrot in...
Gaspar, Daniel; Ginja, Catarina; Carolino, Nuno; Leão, Célia; Monteiro, Helena; Tábuas, Lino; Branco, Sandra; Padre, Ludovina; Caetano, PedroOvine footrot caused by Dichelobacter nodosus (D. nodosus) is a contagious disease with serious economic and welfare impacts in sheep production systems worldwide. A better understanding of the host genetic architecture regarding footrot resistance/susceptibility is crucial to develop disease control strategies that efficiently reduce infection and its severity. A genome-wide association study was performed usi...
Genome-wide association study identifies genetic variants underlying footrot in...
Gaspar, Daniel; Ginja, Catarina; Carolino, Nuno; Leão, Célia; Monteiro, Helena; Tábuas, Lino; Branco, Sandra; Padre, Ludovina; Caetano, PedroThis is the first attempt to identify molecular markers associated with footrot in Portuguese Merino sheep. These findings provide relevant information on a likely genetic association underlying footrot resistance/susceptibility and the potential candidate genes affecting this trait. Genetic selection strategies assisted on the information obtained from this study could enhance Merino sheep-breeding programs, i...
Harmful Algal Blooms on the Portuguese coast: Cross-checking events with remote...
Monteiro, Helena; Goela, Priscila; Pinto, Raquel; Cristina, SóniaPhytoplankton plays a vital role in marine ecosystems, serving as a primary food source for a diverse array of organisms, including commercially important bivalves, crustaceans, and fish. However, in some situations, the proliferation of algae can cause serious economic losses for aquaculture, fishing, and tourism and have major environmental and human health impacts. Increases in the occurrence of toxic phytop...
A metagenomics approach to characterize the footrot microbiome in Merino sheep
Usié, Ana; Leão, Célia; Gaspar, Daniel; Monteiro, Helena; Tábuas, Lino; Bettencourt, Elisa; Caetano, Pedro; Padre, Ludovina; Carolino, NunoIn the Portuguese Alentejo region, Merino sheep breed is the most common breed, reared for the production of meat, dairy, and wool. Footrot is responsible for lameness, decreased animal welfare, and higher production losses, generating a negative economic impact. The disease is caused by Dichelobacter nodosus that interacts with the sheep foot microbiome, to date largely uncharacterized. In fact, Dichelobacter ...
Integrated life cycle assessment of a southern European house addressing differ...
Monteiro, Helena; Soares, NelsonThe construction industry is responsible for a substantial fraction of materials and energy consumption, waste generation, CO2 and other pollutant emissions. Life cycle assessment (LCA) can be used to study and compare the environmental impacts of buildings under different scenarios. This study comparatively assesses the impact of several design options, envelope solutions and operational conditions on the ener...
O Voluntariado nas IES Nacionais: Práticas de Gestão no Instituto Politécnico d...
Marques, C. G.; Monteiro, Helena; Ferreira, Isabel; Cartaxo, MarcoAs Instituições de Ensino Superior para além de agentes de transmissão de conhecimento científico, também devem contribuir para o desenvolvimento de qualidades humanas e de competências sociais dos seus estudantes, de modo a se tornarem cidadãos mais ativos e conscientes. No contexto do Ensino Superior, a prática de voluntariado tem sido estudada, e tem sido demonstrado que os seus estudantes saem beneficiados ...
Life cycle energy of vehicles on lightweighting and alternative powertrain stra...
Monteiro, Helena; Alonso, Rita; Gonçalves, Margarida; Iten, Muriel; Caetano, Nídia S.To improve vehicles environmental performance, different strategies have been explored namely to reduce the use stage energy. In order to avoid problem shifting, a life cycle perspective should be used to compare alternative solutions. This paper aims to compare existing studies focused on life cycle energy (LCE) of vehicles to analyze the impacts and benefits regarding two trending improvement strategies: ligh...
Ovine footrot in Southern Portugal: detection of Dichelobacter nodosus and Fuso...
Albuquerque, Catarina; Cavaco, Sandra; Caetano, Pedro; Branco, Sandra; Monteiro, Helena; Ramos, Marcos; Usié Chimenos, Anabel; Leão, Célia; Botelho, AnaThe Mediterranean climate region of Alentejo in the Southern of Portugal is an important sheep production centre but little is known about the presence and characteristics of Dichelobacter nodosus in association with Fusobacterium necrophorum in the different footrot lesion scores. DNA from 261 interdigital biopsy samples, taken from 14 footrot affected flocks and from three non-affected flocks, were analysed f...

Dixe, Maria dos Anjos Coelho Rodrigues; Querido, Ana; Mendonça, Susana; Sousa, Pedro; Monteiro, Helena; Carvalho, Daniel; Lopes, Paulo; Rodrigues, PedroFalls are a public health problem that cause serious damage to people’s health and health systems. This study aims to estimate the validity and reliability of the Memorial Emergency Department Fall Risk Assessment Tool for the European Portuguese population. The sample included 186 adults from an emergency department of a District Hospital in Portugal. Reliability and precision (inter-rater reliability) are ass...
Indoor Air Quality Improvement Using Nature-Based Solutions: Design Proposals t...
Mata, Teresa M.; Oliveira, Gisela M.; Monteiro, Helena; Silva, Gabriela Ventura; Caetano, Nídia; Martins, António A.Low indoor air quality is an increasingly important problem due to the spread of urbanization. Because people spend most of their time inside, poor indoor air quality causes serious human health issues, resulting in significant economic losses. In this work, the current state of affairs is presented and analyzed, focusing on the current problems and the available solutions to improve the quality of indoor air, ...
