Tomato responses to nitrogen, drought and combined stresses: shared and specifi...
Machado, J.; Fernandes, A. P. G.; Bokor, B.; Vaculík, M.; Kostoláni, D.; Kokavcová, A.; Heuvelink, E.; Vasconcelos, M. W.; Carvalho, S. M. P.Crops are often subjected to various abiotic stresses and interactions between them may occur, but how plants cope with them remains poorly understood. This study explored how combined nitrogen and drought stress impact tomato vascular stem anatomy, nutrient partitioning and amino acids profile. Tomato seedlings were exposed to control (CTR; 100N + 100%W), N stress (N; 50%N), drought stress (W; 50%W), or combin...
Carcass traits of pure Alentejano breed males reared outdoors and subjected to ...
Martins, J.M.; Tomaz, P.; Hernández-Garcia, F.; Izquierdo, M.; Lopes, J.; Machado, J.; Carreira, E.; Braz, M.; Payan-Carreira, R.; Charneca, R.Rearing intact male pigs may lead to an off-odor and flavor in meat and fat known as boar taint, especialy in animals slaughtered at older ages and high body weights (BW). This is a particular issue for a portuguese local breed, the Alentejano (AL) pig. To address this, males from this breed are generally physically castrated. However, with the potential prohibition of this surgical procedure in the European Un...
Effects of two immunocastration protocols on meat quality of pure Alentejano br...
Martins, J.M.; Tomaz, P.; Hernández-Garcia, F.; Izquierdo, M.; Lopes, J.; Machado, J.; Carreira, E.; Charneca, R.The Alentejano pig, a local portuguese breed, is known for its high-quality PDO and PGI meat and meat products. Traditionally, these animals are reared to older ages and heavier weights, with male castration used to prevent boar taint, which adversely affects meat flavor and odor, as well as to reduce aggressive behaviors. With the impending ban on surgical castration within the European Union, alternative solu...
Salmonella Saintpaul outbreak associated with cantaloupe consumption, the Unite...
McGeoch, L.J.; Hoban, A.; Sawyer, C.; Rabie, H.; Incident Team; Painset, A.; Browning, L.; Brown, D.; McCarthy, C.; Nelson, A.; Firme, A.; Pista, A.In September 2023, the UK Health Security Agency identified cases of Salmonella Saintpaul distributed across England, Scotland, and Wales, all with very low genetic diversity. Additional cases were identified in Portugal following an alert raised by the United Kingdom. Ninety-eight cases with a similar genetic sequence were identified, 93 in the United Kingdom and 5 in Portugal, of which 46% were aged under 10 ...
Outbreak of monkeypox in an STD clinic in Lisbon
Caldeira, M.; Fernandes, C.; Neves, J.; João, A.; Calado, R.; Pinto, A.R.; Borrego, M.J.; Cordeiro, R.; Machado, J.; Pelerito, A.; Lopes de Carvalho, I.We present the preliminary results of the first 43 patients with a definitive diagnosis of human infection with monkeypox virus, from the dermatovenereology department of Hospital Santo António dos Capuchos, Lisbon, in May 2022 [...].
Ongoing monkeypox virus outbreak, Portugal, 29 April to 23 May 2022
Duque, M.P.; Ribeiro, S.; Martins, J.V.; Casaca, P.; Leite, P. P.; Tavares, M.; Mansinho, K.; Duque, L.M.; Fernandes, C.; Cordeiro, R.; Borrego, M.J.Up to 27 May 2022, Portugal has detected 96 confirmed cases of monkeypox. We describe 27 confirmed cases (median age: 33 years (range: 22–51); all males), with an earliest symptom onset date of 29 April. Almost all cases (n = 25) live in the Lisbon and Tagus Valley health region. Most cases were neither part of identified transmission chains, nor linked to travel or had contact with symptomatic persons or with ...
Remote Gait type classification system using markerless 2D video
Albuquerque, P.; Machado, J.; Verlekar, T.; Correia, P. L.; Soares, L. D.Several pathologies can alter the way people walk, i.e., their gait. Gait analysis can be used to detect such alterations and, therefore, help diagnose certain pathologies or assess people’s health and recovery. Simple vision-based systems have a considerable potential in this area, as they allow the capture of gait in unconstrained environments, such as at home or in a clinic, while the required computations c...
Educar para a saúde laboral: perceção da qualidade de vida em relação a variáve...
Moreira, S.; Miranda, A.; Lima, C.; Gonçalves, C.; Mesquita, Cristina; Lopes, Sofia; Machado, J.; Santos, Paula ClaraOs trabalhadores de escritório permanecem em posições estacionárias durante longos períodos e estão sujeitos a elevadas cargas laborais que podem interferir com a Qualidade de Vida, em interação com caraterísticas do trabalhador (como personalidade, autonomia, competência e empenho no trabalho). A Qualidade de Vida é um conceito multidimensional influenciado por fatores sociodemográficos, de saúde e trabalho, q...
Impairment of swimming performance in Tritia reticulata (L.) veligers under pro...
Fonseca, J.G.; Laranjeiro, F.; Freitas, D. B.; Oliveira, I. B.; Rocha, R. J. M.; Machado, J.; Hinzmann, M.; Barroso, C. M.; Galante-Oliveira, S.Tritia reticulata (L.) is a neogastropod ubiquitous in the coastal communities of the NE Atlantic. Its life cycle relies on the swimming performance of planktonic early life stages, whose sensitivity to the climate conditions projected for the near future, namely of ocean acidification (OA) and warming (W), is, to our best knowledge, unknown. To examine the resilience of larval stages to future environmental co...
Accelerated aging of anticorrosive coatings: Two-stage approach to the AC/ DC/A...
da Silva Lopes, T.; Lopes, T.; Martins, D.; Carneiro, C.; Machado, J.; Adélio MendesOrganic coatings are nowadays the most common and cost-effective approach to extend the service life of metallic structures subjected to weathering conditions. The development of new and more effective protective coatings is closely related to the rapid assessment of the anticorrosive performance before industrialization. Currently, the coating/metallic substrate system evaluation is made using accelerated stan...
