Screening wild birds for tick-borne zoonotic pathogens in Portugal
Loureiro, Filipa; Mesquita, João R.; Cardoso, Luis; Santos-Silva, S.; Moreira, G.; Bento, J. T.; Silva, F.; Barradas, P. F.; Matos, M.Wild birds may be involved in the transmission of agents of infectious diseases, including zoonoses, a circumstance which raises a number of public and animal health issues. Migratory bird species play a significant role in the introduction of tick-borne pathogens to new geographic areas, contributing to the dissemination of various etiological agents. This preliminary study aimed to assess the occurrence of fo...
Experimental observation of the motion of ions in a resonantly driven plasma wa...
Turner, M.; Walter, E.; Amoedo, C.; Torrado, N.; Lopes, N.; Sublet, A.; Bergamaschi, M.; Pucek, J.; Mezger, J.; van Gils, N.; Verra, L.We show experimentally that an effect of motion of ions, observed in a plasma-based accelerator, depends inversely on the plasma ion mass. The effect appears within a single wakefield event and manifests itself as a bunch tail, occurring only when sufficient motion of ions suppresses wakefields. Wakefields are driven resonantly by multiple bunches, and simulation results indicate that the ponderomotive force ca...
Can an Antisense Oligonucleotide Exon Skipping Rewrite the Story of N-Acetylglu...
Gonçalves, M.; Moreira, L.; Encarnação, M.; Gaspar, P.; Duarte, A.J.; Santos, J.I.; Coutinho, M.F.; Prata, M.J.; Omidi, M.; Pohl, S.; Silva, F.Mucolipidosis II (ML II) is a Lysosomal Storage Disorder caused by N-acetylglucosamine-1-phosphotransferase (GlcNAc-PT) deficiency, which impairs the trafficking of lysosomal hydrolases. Of all ML II mutations, c.3503_3504delTC in GNPTAB exon 19 is the most frequent, making it a good target for a personalized therapy. Here, we explored an innovative therapeutic strategy based on the use of antisense oligonucleo...
The Portuguese Large Wildfire Spread database (PT-FireSprd)
Benali, A.; Guiomar, N.; Gonçalves, H.; Mota, B.; Silva, F.; Fernandes, P.M.; Mota, C.; Penha, A.; Santos, J.; Pereira, J.M.C.; Sá, A.C.L.Wildfire behaviour depends on complex interactions between fuels, topography, and weather over a wide range of scales, being important for fire research and management applications. To allow for significant progress towards better fire management, the operational and research communities require detailed open data on observed wildfire behaviour. Here, we present the Portuguese Large Wildfire Spread database (PT...
Saliva Immunoglobulin Concentrations Are Associated with Colostrum Intake and w...
Silva, F.; Lamy, E.; Infante, P.; Conceição, C.; Cerqueira, J.; Ramalho, J.; González-Cabrera, M.; Caetano, P.; Martins, L.; Silva, S.The transfer of passive immunity (TPI) is vital for newborn calf health and is typically assessed through blood sampling to measure serum or plasma IgG or total protein levels. Saliva offers a less invasive alternative. This study evaluated the potential of saliva for assessing TPI. Saliva and serum samples were collected from 20 calves at birth and on days 1, 2, and 7 of life to measure IgG, IgA, IgM, and tota...
Mecanismos homeostáticos e homeorréticos decorrentes da aclimatização sazonal e...
Silva, F.; Cachucho, L.; Matos, C.; Geraldo, A.; Conceição, C.; Lamy, E.; Infante, P.; Pereira, A. M. F.The aim of this study was to compare the physiological responses of dairy cows, Holstein-Frisian breed, with different milk yield potential regarding the seasonal acclimatisation process. Using milk production values adjusted to 305 days in milk, 6 and 7 multiparous cows with a milk yield lower than 9000 kg (BP) and equal or higher that 9000 kg (AP), respectively, were selected. All cows were evaluated during 5...
Pastoreio contínuo versus diferido: Impacto na utilização de pastagens naturais...
Carreira, Emanuel; Serrano, João; Silva, F.; Pinto Gomes, C.; Lopes de Castro, J.; Carvalho, M.; Pereira, A.Objetivou-se avaliar o efeito da aplicação de calcário dolomítico e de diferentes sistemas de pastoreio, na taxa de utilização da pastagem e no número de dias de pastoreio. Assim, constituíram-se 4 tratamentos: P1UC- sem aplicação de calcário dolomítico (U) e pastoreio contínuo (PC- 7 ovelhas/ha); P2UD- U e pastoreio diferido (PD- 16 ovelhas/ha); P3TD- aplicação de calcário dolomítico (T) e PD; P4TC- T e PC. A ...
Sheep grazing preferences on pastures in the Montado: effect of soil amendment ...
Carreira, Emanuel; Serrano, João; Silva, F.; Gomes, C.; Castro, J.; Carvalho, M.; Pereira, A.The aim this study was to evaluate the effect of dolomitic limestone application (uncorrected, U and corrected, C) and two sheep grazing systems (continuous, CG and deferred, DG) in preferred grazing areas, in natural pastures. The stocking rate was of 7 sheep/ha in CG and 16 sheep/ha in DG. In 4 plots of 1ha each, four treatments were constituted: T1 (UCG); T2 (UDG); T3 (CDG); and T4 (CCG). The study was carri...
Gestão de pastagens no Montado com diferentes sistemas de pastoreio: Impacto na...
Carreira, Emanuel; Serrano, João; Silva, F.; Gomes, C.; Castro, J.; Carvalho, M.; Pereira, A.O Montado/Dehesa é um ecossistema agro-silvo-pastoril característico da região sudeste da Península Ibérica. A gestão das pastagens neste ecossistema é complexa, devido às interações entre estas e o solo, as árvores, os animais em pastoreio e o clima. As preferências alimentares dos ovinos em pastoreio podem ser influenciadas por fatores como a altitude das parcelas, o encabeçamento animal, a disponibilidade de...
The Relevance of Plant-Based Diets and Micronutrient Supplementation for Body C...
Pinheiro, C.; Silva, F.; Rocha, I.; Martins, C.; Giesteira, L.; Dias, B.; Lucas, A.; Alexandre, A.M.; Ferreira, C.; Viegas, B.; Bracchi, I.Objectives: This study aimed to compare the anthropometry and body composition of vegetarian and omnivorous adults living in Portugal, while exploring nutritional and health parameters underlying observed differences. Methods: 425 omnivorous (OMNI), lacto-ovo-vegetarian (LOV), or vegan (VEG) healthy adults were recruited. Anthropometry was measured, and bioelectrical impedance analysis was performed. Participan...
