Assessing the Potential of Gabiroba Fruit Waste as an Oil Source via Ultrasound-Assisted Extraction: Physicochemical Parameters, Chemical Profile, and Biological Properties

This study aimed to evaluate the impact of ultrasound-assisted extraction (UAE) on the chemical composition and biological activities of gabiroba waste oil (GWO), compared to conventional Soxhlet extraction (SE). GWO was characterized for carotenoid content and analyzed by GC-MS...

Maternal Diabetes and a High-Fat Diet Program Transgenerational Dysfunction of the Endocrine Pancreas in Offspring

Background Maternal diabetes and exposure to a high‑fat diet (HFD) disrupt pancreatic development and glucose homeostasis, potentially inducing transgenerational metabolic changes. Objective Investigate how maternal diabetes and HFD exposure impact the endocrine pancreas across g...

Laminin-Derived Peptides and Isoforms: A Multifaceted Review of Their Roles in Cancer, Neurodegeneration, Inflammation, Tissue Regeneration, and Exercise Physiology

Background: Laminins are heterotrimeric basement membrane glycoproteins whose chain composition, molecular processing, receptor engagement, and cellular source determine their biological effects. Methods: We conducted an integrative narrative search of PubMed and manually screene...

Theory of Electron Correlation and Disorder in CrSb Altermagnet

Motivated by the altermagnet order reported for CrSb and evidence of electron correlations in this compound, we address the role of dynamical Coulomb interactions on its hexagonal Dirac fermion regime. We find that a Dirac-to-Fermi liquid crossover develops near half-filling upon...

Warming causes higher bilateral asymmetry in aquatic hemipterans from geothermal streams

Abstract Increase in temperature associated with climate change may alter community structure and disrupt developmental stability in ectothermic organisms. Using a natural geothermal gradient (20.6–40.3 °C) in Neotropical streams in central-western Brazil, we investigated how war...

Influence of therapeutic protocols and clinicopathological parameters on survival of dogs with leishmaniasis

Visceral leishmaniasis (VL) is a neglected disease caused by the protozoan Leishmania infantum , characterized by high lethality and predominantly affecting populations in conditions of social vulnerability. In Brazil, domestic dogs are the main urban reservoirs, and the treatmen...

Adherence, motivational factors, and injury rates in runners using minimalist vs. conventional shoes: A cross-sectional study of 4719 Brazilian runners

Background In the early 2010s, a movement advocating a more natural running style, such as running in minimalist shoes, emerged. However, little is known about runners' adherence to these shoes, interest in them, and injury rates associated with them. Objective To investigate adh...

Rapid increase of climate extremes reveals new areas of concern in Amazonia

Abstract Amazonia is highly sensitive to climate extremes, yet we lack an Amazon-wide assessment that examines the spatial-temporal changes in these extreme conditions. We address this within seasons and across the hydrological year, using a quantiles approach that integrates the...

Assemblage structure and ecological functions of dung beetles in exotic pastures in the Southwestern Amazon

Abstract The implementation of exotic pastures in the Amazon causes drastic negative impacts on its biodiversity. Nevertheless, some species with the ability to colonize pastures may provide important ecosystem services for livestock development in tropical pastures, as in the Am...

Improving Primary Healthcare: Applying Grapevine (Vitis vinifera) Principles to Lebanon’s Vision 2030

Background/Objectives: While Lebanon’s Vision 2030 prioritizes strengthening Lebanon’s chronically constrained, fragmented, and shocked primary healthcare system, implementation is hindered by weak sensing mechanisms, misaligned spatial distribution, and poorly integrated referra...

Fetal pneumonia and polyarthritis associated with Ureaplasma diversum infection in an aborted beef cattle fetus in Brazil

Abstract Ureaplasma diversum is an opportunistic bovine pathogen associated with reproductive disorders, including infertility, granular vulvovaginitis, placentitis, and abortion; however, detailed descriptions of fetal osteoarticular lesions remain exceptionally uncommon. This r...

Molecular and Phylogenetic Identification of Fungal Taxa Associated with Soybean Anomaly in Brazil

Soybean anomaly, characterized by immature pod and grain rot, has been reported in Brazilian soybean production fields, but the fungal taxa associated with symptomatic tissues remain poorly characterized. This study aimed to identify fungi associated with soybean plants showing a...

Sucessão ecológica, entropia e o Modelo Autonomia-Heteronomia para análise dos sistemas agrícolas

It is proposed a agronomic analytical model, Autonomy-Heteronomy, for description and analysis of agricultural systems. Autonomous systems are characterized by preferential use of local resources and strategies to meet local or regional needs. They are systems of low entropy and...

Fire absence favours tree growth above the flame zone threatening South American Cerrado vegetation

Tropical savannas, including the Brazilian Cerrado, face significant woody encroachment linked to fire suppression. We investigated floristic composition, horizontal and vertical structure, and Enhanced Vegetation Index (EVI) time series in a 1-hectare plot within Chapada dos Gui...

Effect of carcass electrical stimulation on sheep and goat meat quality: a meta-analysis study

Context The utilization of electrical stimulation (ES) in small ruminant carcasses is less common than in beef processing facilities. Nevertheless, ES shows promise in mitigating cold shortening and improving meat quality traits in small ruminants. Aim This meta-analysis assessed...

Gödel-symmetric backgrounds and explicit spacetime symmetry breaking

Abstract Explicit diffeomorphism breaking in gravitational theories with nondynamical background fields is constrained by the compatibility between the modified Einstein equations and the contracted Bianchi identities. We implement an isometry-based approach in which the backgrou...

Assessing fish diversity in the Amazon: The impact of primers and reference libraries in eDNA surveys

Abstract Selecting primers for DNA amplification poses a challenge in environmental DNA (eDNA) studies, particularly in biodiverse tropical ecosystems. Researchers must balance taxonomic coverage, primer specificity, and study feasibility when choosing between a single primer pai...

Thermoforesis from Generalized Caldeira-Leggett Models

Abstract The standard Caldeira-Leggett model addresses the problem of Brownian motion in a thermal equilibrium environment. Here, we look for generalizations of the Caldeira-Leggett model to account for thermal gradients in the environment. We devise two types of models, and disc...

Exact Boundary Controllability for Wave Equations With Space Variable Potential

ABSTRACT In this article, we study an exact boundary controllability problem for a wave equation with a potential that varies in the space on non‐smooth domains of , . The potential considered is a positive space variable function which has the short‐range property, that is when...

Contrasting effects of fire on reproductive structures: prescribed burns advance and extend flowering but reduce fruiting of Macairea radula (Bonpl.) DC (Melastomataceae) in the Brazilian Cerrado

Abstract Fire triggers flowering, stimulating and advancing flower production and, consequently, fruiting in some plants of the Cerrado , the Brazilian savanna. Integrated Fire Management (IFM) has been applied in several protected areas in the Cerrado to simulate natural fire re...
