Assessment of Lumbar Vertebrae L1-L7 and Proximal Femur Microstructure in Sheep as a Large Animal Model for Osteoporosis Research.

Sheep have been widely used as a model for osteoporosis research. This study aimed to characterise changes in microstructure and composition in lumbar vertebrae L1-L7 and the proximal femur after implementation of a bone loss induction protocol (in this species). A sham control and experimental group (glucocorticoid-treated ovariectomized sheep) were used ( = 6/group), with a study duration up to the 24th postoperative week.

Evaluation of thymol application for anaesthesia of adult zebrafish.

The use of anaesthetics has become extremely important in promoting responsible welfare practices in aquaculture and research. However, adverse reactions and side effects have been described for commonly used anaesthetics such as MS-222 and eugenol. This study examined thymol as a new anaesthetic for adult zebrafish (Danio rerio), a species for which no previous thymol anaesthesia studies have been reported.

Thymol and menthol as anaesthetics for short transportation of zebrafish larva.

Transportation-induced stress is a major concern in aquaculture, often causing physiological and behavioural disruptions in fish. To alleviate these effects, anaesthesia is commonly used, but the most widely used anaesthetics, MS-222 and eugenol, have been linked to adverse effects, and alternatives are lacking. This study evaluated the anaesthetic efficacy of thymol and menthol, in comparison with MS-222 and eugenol, under stress conditions induced by a simulated 4-h transportation of 96 hpf zebrafish larvae.

Hormone receptor discrepancy and molecular subtype changes in canine mammary carcinomas and synchronous lymph node metastasis.

Mammary tumors are the most prevalent neoplasms in intact female dogs; up to 50 % are considered malignant and have the potential to metastasize to regional lymph node and distant organs. Changes in tumor molecular subtype, including its receptor status, can occur during mammary tumor progression. This study aimed to explore hormone receptor discrepancies and the relationship between molecular subtypes in primary mammary tumors (PTs) and paired lymph node metastases (LNMs).

Advancing Zebrafish () Welfare Using Immersion Analgesics.

Growing evidence of pain perception in fish has raised concerns about their welfare in different contexts, including research and aquaculture, where potentially painful procedures are standard. Despite ongoing efforts to advance fish analgesia, the field remains underdeveloped, particularly regarding less invasive methods that could improve welfare, such as immersion-based analgesia. As one of the most widely used models in research, zebrafish () are often at the front of these concerns.

Assessing Q Fever Exposure in Veterinary Professionals: A Study on Seroprevalence and Awareness in Portugal, 2024.

Due to their frequent contact with animals, veterinarians may be at preferential risk of exposure due to occupational contact with livestock. This study assesses the seroprevalence and risk factors associated with seropositivity in Portuguese veterinarians. A cross-sectional study compared IgG anti- in veterinarians' sera to a demographically matched control group.

Harnessing deep learning to monitor people's perceptions towards climate change on social media.

Social media has become a popular stage for people's views over climate change. Monitoring how climate change is perceived on social media is relevant for informed decision-making. This work advances the way social media users' perceptions and reactions towards climate change can be understood over time, by implementing a scalable methodological framework grounded on natural language processing.

A Revisit of Plant Food Waste Along Food Supply Chains: Impacts and Perspectives.

More than one billion tons of the food produced in the world ends up being wasted every year, accounting for about one-third of the food produced globally. For this reason, the problem of food waste management has been the focus of the different actors intervening in the food supply chains, who recognize that food waste has not only environmental but also economic and social impacts. This review focuses on foods of plant origin wasted at different stages of their life, namely primary production, transformation/processing, transportation, sales, catering and the domestic level.

Non-Alcoholic Wines: Sensory Pleasantness and Health Benefits.

Non-alcoholic wine is becoming popular as a healthier alternative to traditional wine, offering potential health benefits without the risks of alcohol consumption. Sensory attributes, such as taste and aroma, significantly influence consumer preferences, with sweet, sour, and balanced fragrances favored over bitter or medicinal notes. A lower alcohol content can enhance the complexity of sensory properties, suggesting that non-alcoholic wines provide an appealing experience.

Almond By-Products: A Comprehensive Review of Composition, Bioactivities, and Influencing Factors.

One of today's major environmental and economic challenges is the fight against both agro- and industrial-waste. Almond production and industrial processing exemplifies this issue, as it generates tons of waste and by-products, with hulls and shells accounting for about 70% of the total fruit's weight while skins represent about 6% of the shelled kernel. Since the edible kernel, about 23% of the total fruit weight, holds the highest commercial value, there has been growing interest within the scientific community in exploring the potential of these by-products.

Food Habits of the Wolf in a Low-Density Territory in the Northeast of Trás-os-Montes (Portugal).

The study of carnivores' diets is an important conservation tool, which can minimize conflicts with different stakeholders and provide proper substantiations for management measures. The main aim of this study was to understand the diet of a small, isolated pack named Mogadouro Sul, present in the Northeast of Trás-os-Montes (Portugal). Scat analysis was the method used to determine what wolves consumed.

Renal Biomarkers in Companion Animals-A Review.

Recent advancements in molecular biology have led to the discovery of potential biomarkers for the diagnosis of acute kidney disease (AKD) and chronic kidney disease (CKD). The use of multiple biomarkers in the diagnosis of kidney disease has the potential to enhance both specificity and sensitivity, enabling early detection and intervention that could ultimately reduce morbidity and mortality rates. This review provides an overview of studies on urine and blood biomarkers and examines their utility and significance in various clinical settings.

Current Biological Insights of Mill. to Improve Crop Sustainability to Climate Change.

The sustainability of agriculture is seriously threatened by climate change. In Europe, chestnut ecosystems, which are growing mainly in Mediterranean climate, are facing during summertime increasing of heat and drought stresses. These induce fragilities on trees, leading to a reduction in productivity and predisposing them to pest and disease attacks.

Fire suppression and land-use strategies drive future dynamics of an invasive plant in a fire-prone mountain area under climate change.

Woody invasive alien species can have profound impacts on ecosystem processes and functions, including fire regulation, which can significantly affect landscape resilience. Acacia dealbata, a widespread invasive alien plant in the Iberian Peninsula, holds well-known fire-adaptation traits (e.g.

Chitosan-Enclosed Menadione Sodium Bisulfite as an Environmentally Friendly Alternative to Enhance Biostimulant Properties against Drought.

Biostimulants are an interesting strategy to increase crop tolerance to water deficits, and there is an extensive bibliography on them. However, most of them need to be treated continuously to increase protection throughout the growth cycle. In this context, we chose menadione sodium bisulfite, whose protective effect against water deficit has been previously demonstrated but only for a short period of time.
