Perceptions of change in the environment caused by the COVID-19 pandemic: Impli...
Hidalgo-Triana, N.; Picornell, A.; Reyes, S.; Circella, G.; Ribeiro, H.; Bates, A. E.; Rojo, J.; Pearman, P. B.; Vivancos, J. M. Artes; Nautiyal, S.COVID-19 lockdown measures have impacted the environment with both positive and negative effects. However, how human populations have perceived such changes in the natural environment and how they may have changed their daily habits have not been yet thoroughly evaluated. The objectives of this work were to investigate (1) the social perception of the environmental changes produced by the COVID-19 pandemic lock...
Avaliação da qualidade do colostro e de transferência de imunidade passiva em b...
Cabral, J.; Pereira, C.; Ribeiro, H.; Pardal, P.A ingestão e a absorção de quantidades adequadas de imunoglobulinas colostrais afiguram-se essenciais para estabelecer a imunidade do vitelo recém nascido, até que o seu sistema imunitário se torne competente. Foi nosso objetivo avaliar a qualidade do colostro e o grau de transferência de imunidade passiva (TIP) obtido nos vitelos, no período de Primavera, numa vacada comercial de bovinos de carne cruzados, exp...
The Paradox cl. ‘Vlach’ multiplication and rooting rates are strongly affected ...
Campos, M. D.; Peixe, A.; Barroso, J.; Rato, A. E.; Ribeiro, A.; Ribeiro, H.The multiplication and rooting rates achieved from in vitro cultured explants of Paradox cl. ‘Vlach’, proved to be highly affected by their position in the original shoot. Explants taken until the 3 rd internode below the apical meristem, when systematically subcultured each 30 th days, lost their multiplication capacity on each subculture, their regeneration efficiency becoming almost null after 5 subcultures....
The Acacia bark phytotoxic potential: A non-synthetic bio-herbicide

Variable-rate mechanical pruning: a new way to prune vines
Botelho, M.; Cruz, A.; Mourato, C.; Castelo-Branco, J.; Ricardo-da-Silva, J.; Ribeiro, H.; Braga, R.Hand pruning is a precise operation, with a visual evaluation of each grapevine to adapt bud load to the vigor. With the advent of mechanical pruning the individual evaluation is lost, and the plant balance relies solely on self-regulation mechanisms. However, precision agriculture provides remote sensing tools for vigor evaluation that allow adapting mechanical pruning to the vine vigor. Variable-rate mechanic...
Low-temperature hydrothermally treated Eucalyptus globulus bark: From by-produc...
Chemetova, C.; Mota, D.; Fabião, A.; Gominho, J.; Ribeiro, H.Worldwide, the circular economy approach increased the need of waste-streams minimization, promoting byproducts re-circulation into the value chain which creates sustainable industrial synergies. Eucalyptus globulus bark fiber is a waste from pulp and paper industry that can be re-used in horticultural applications. This work aims to use low-temperature hydrothermally treated E. globulus bark as a fiber materia...
Response of Mycorrhizal ’Touriga Nacional‘ Variety Grapevines to High Temperatu...
Nogales, A.; Ribeiro, H.; Nogales-Bueno, J.; Hansen, L.D.; Gonçalves, E.F.; Coito, J.L.; Rato, A.E.; Peixe, A.; Viegas, W.; Cardoso, HéliaHeat stress negatively affects several physiological and biochemical processes in grapevine plants. In this work, two new methods, calorespirometry, which has been used to determine temperature adaptation in plants, and near-infrared (NIR) spectroscopy, which has been used to determine several grapevine-related traits and to discriminate among varieties, were tested to evaluate grapevine response to high temper...
Chemical inhibition of β-glucocerebrosidase does not affect phagocytosis and ea...
Ribeiro, H.; Rocha, M. I.; Castro, H.; Macedo, M. F.Gaucher disease is a lysosomal storage disease in which a genetic deficiency in β-glucocerebrosidase leads to the accumulation of glycosphingolipids in lysosomes. Macrophages are amongst the cells most severely affected in Gaucher disease patients. One phenotype associated with Gaucher macrophages is the impaired capacity to fight bacterial infections. Here, we investigate whether inhibition of β-glucocerebrosi...
SCARB2 mutations as modifiers in Gaucher disease: the wrong enzyme at the wrong...
Coutinho, M.F.; Lacerda, L.; Gaspar, A.; Pinto, E.; Ribeiro, I.; Laranjeira, F.; Ribeiro, H.; Silva, E.; Ferreira, C.; Prata, M.J.; Alves, S.Unlike most lysosomal proteins, β-glucocerebrosidase (GCase), the hydrolase defective in Gaucher disease (GD), is delivered to lysosomes through its interaction with the transmembrane protein LIMP2. A few years ago, mutations in its coding gene, SCARB2, were reported to modify the severity of GD phenotype. The existence of a great variety of GD phenotypes is well-known, with numerous patients who carry identica...
