Pathological alterations in the liver of post-juvenile African Catfish (Clarias gariepinus) exposed to sublethal concentrations of the herbicide Glyphosate.
The use of histopathological techniques allows investigators to examine specific target organs and cells to determine how they are affected by exposure to environmental chemicals like pesticides. Moreover, it offers a means of detecting acute and chronic harmful effects of exposure in the tissues and organs of individual animals. In this study, histopathological alterations in the liver of post-juvenile African catfish Clarias gariepinus exposed to varying concentration of the commonly used herbicide glyphosate (IPA 360g/L) were used as biomarkers of effect, and alterations were both concentration and time specific. Cellular rupture, aggregation of inflammatory cells, vacuolar degeneration in the hepatocytes, focal areas of necrosis, and rupture of blood vessels that resulted in haemorrhage were characteristic of Glyphosate-exposed liver. The observed alterations in the liver of C. gariepinus further provide evidence to support the use of pathological change in fish as an indicator for monitoring the effect of exposure to low levels of toxicants, which are capable of altering the physiological profile of an organism.

Nutritional characteristics and minerals of Lardosa cowpea landraces : a strategic legume species for the future
Cowpeas have been cultivated at least since the 8th century BC. [1; 2]. This grain legume (Vigna unguiculata L. Walp.), one of Africa's natural food gifts to the world, is characterized by its high nutritional value, ability to fix nitrogen and great tolerance to drought. The tolerance of this legume to low fertility soils, high temperatures and scarce water regimes makes this one of the most resistant crops to adverse edaphoclimatic conditions. It is certainly a very important culture in southern European countries like Portugal.Cultivar-Rede de competências para o desenvolvimento sustentável e inovação no setor Agroalimentar (CENTRO-01-0145-FEDER-000020).info:eu-repo/semantics/publishedVersio

Orange snacks as a solution for orange surplus in Portugal
In the summer of 2022, Portugal experienced a downfall of the price of oranges, mainly due to
pressure of the agricultural commodity market and the change in trade dynamics in Europe due
to the war in Ukraine. One way to add value to a product is to transform it into something new.CULTIVAR (CENTRO-01-0145-FEDER-000020) e FUSILIinfo:eu-repo/semantics/publishedVersio
Crispy orange: a multi-purpose ready-to-eat snack
Póster premiado no evento IMTFWith the war in Ukraine reshaping world trade, there is now a surplus of orange production in
Europe, affecting the price in Portugal. Algarve is no exception, where producers are offering the
fruit for lack of buyers. An innovative solution is on the agenda: transforming this Mediterranean
diet fruit into a crispy ready-to-eat snack. The crispy orange snack is made exclusively from
dehydrated oranges (and no other ingredients) and is not yet available in the market. Not only can
this product be made from surplus orange production, but it can also be used in a variety of ways,
including as a crunchy, ready-to-eat snack, as an edible cake topper, or even as an ingredient in
beverages such as sparkling and tonic water, or gin. Following development, the product was fully
characterized regarding nutritional value, water activity (aw), microbiology and sensory analysis
with 66 consumers. Interestingly, unlike other orange products such as 100% orange juice, the
crispy orange snack has a high fibre content (10% of the recommended daily dose). This is a major
point as fibre is essential for regulating blood sugar levels. Furthermore, 95.5% of consumers who
tested the product would buy it if it were available.info:eu-repo/semantics/publishedVersio
Gravitational Collapse of Phantom Fluid in (2+1)-Dimensions
This investigation is devoted to the solutions of Einstein's field equations
for a circularly symmetric anisotropic fluid, with kinematic self-similarity of
the first kind, in -dimensional spacetimes. In the case where the radial
pressure vanishes, we show that there exists a solution of the equations that
represents the gravitational collapse of an anisotropic fluid, and this
collapse will eventually form a black hole, even when it is constituted by the
phantom energy.Comment: 10 page
Potential Use of Near-Infrared Spectroscopy to Predict Fatty Acid Profile of Meat from Different European Autochthonous Pig Breeds
Autochthonous pig breeds provide products of differentiated quality, among which quality control is difficult to perform and insufficient for current market requirements. The present research evaluates the predictive ability of near‐infrared (NIR) spectroscopy, combined with chemometric methods as a rapid and affordable tool to assure traceability and quality control. Thus, NIR technology was assessed for intact and minced muscle Longissimus thoracis et lumborum samples collected from 12 European autochthonous pig breeds for the quantification of lipid content and fatty acid composition. Different tests were performed using different numbers of samples for calibration and validation. The best predictive ability was found using minced presentation and set with 80% of the samples for the calibration and the remaining 20% for the external validation test for the following traits: lipid content and saturated and polyunsaturated fatty acids, which attained both the highest determination coefficients (0.89, 0.61, and 0.65, respectively) and the lowest root mean square errors in external validation (0.62, 1.82, and 1.36, respectively). Lower predictive ability was observed for intact muscles. These results could contribute to improve the management of autochthonous breeds and to ensure quality of their products by traditional meat industry chains
Será a laranja-crocante uma solução para a valorização do setor dos citrinos?
Embora originária do sudoeste asiático, a laranja é um fruto que está presente na bacia do mediterrâneo há
vários séculos. A laranjeira tem sido cultivada na Península Ibérica desde o século IX1 e, embora não
nativa, a sua adaptabilidade às condições edafoclimáticas locais, em conjugação com o valor
nutricional e os benefícios para a saúde dos seus frutos, fazem da laranja um dos componentes incontornáveis
da dieta Mediterrânica2. A Europa (terceira maior produtora mundial) conta com os países mediterrânicos,
Portugal inclusive, um dos maiores produtores.M.C., A.C., A.M., V.V. são financiados pelo projeto Cultivar Iniciativa cofinanciada pelo Centro 2020, pelo Portugal 2020 e pela União Europeia através do FEDER.
