Spore-based arbuscular mycorrhizal fungal community in an olive cultivation area in southern Brazil

Abstract Arbuscular mycorrhizal fungi (AMF), belonging to the phylum Glomeromycota, establish symbiotic associations with approximately 90% of terrestrial plant species and play a key role in nutrient acquisition, tolerance to abiotic stresses, and agroecosystem functioning. Alth...

As arenas de Construção do Conhecimento Agroecológico como espaços para emergência de um “novo profissionalismo” da ação extensionista.

The present text approaches the transition that the professionals of the Technical Assistance and Rural Extension in Brazil points out, through the analysis of the experience of Dom Feliciano-RS, the possibility of the emergence of a space of change from a diffusionist perspectiv...

Theoretical Analysis of Androstenone Adsorption on Chimpanzee and Gorilla Olfactory Receptors (G‐Protein): Statistical Physics Modeling, Molecular Docking Simulation, and Thermodynamic Investigation

ABSTRACT An advanced theory based on statistical physics was applied to microscopically investigate androstenone adsorption and its relationship with olfactory perception in chimpanzees and gorillas. For this purpose, dose–response curves of androstenone on olfactory receptors of...

Common genetic mechanisms between obesity and COVID-19 severity: unravelling pleiotropic loci and biological pathways

Abstract COVID-19 and obesity are complex conditions marked by immune and metabolic dysfunction, with the former still ranking among the leading causes of death from infectious diseases worldwide and the latter reaching pandemic proportions. Clinical evidence consistently shows t...

Wood Properties: Measurement, Modeling, and Future Needs

Wood science has long been shaped by a fundamental challenge: the properties that determine material performance are intrinsically heterogeneous, anisotropic, scale-dependent, and sensitive to environmental and processing conditions [...]

Endovascular therapy versus best medical treatment in pediatric acute ischemic stroke: A systematic review and meta-analysis

Purpose This systematic review and meta-analysis evaluates endovascular therapy (EVT) versus best medical treatment (BMT) in pediatric acute ischemic stroke (AIS) due to large-vessel occlusion. Methods Systematic searches were conducted across PubMed, Cochrane, and Embase, incept...

Comparison of Fogarty and Vollmar thrombectomy for chronic jugular thrombosis in horses

Abstract Background Chronic jugular vein thrombosis may result in persistent venous obstruction and impaired head drainage. Although surgical thrombectomy is performed in selected cases, experimental comparisons between mechanical techniques for chronic thrombus removal in horses...

Phenotypes of painful TMDs and bruxism based on clinical, psychosocial and somatosensory features: a cluster analysis

To identify pain phenotypes among individuals with bruxism and painful temporomandibular disorders (TMD) by integrating clinical, psychosocial, and somatosensory variables. This cross-sectional observational study included 54 adults who self-reported and were clinically assessed...

Data and channel-aware device selection for split learning in resource-constrained B5G/6 G networks

Abstract Split learning (SL) is a promising distributed learning approach for fifth-generation/sixth-generation (B5G/6 G) networks. However, its performance is affected by bandwidth constraints and statistical heterogeneity in the data. Prior works have considered either channel-...

Optimizing mini nutritional assessment as a prognostic tool in oncology: evidence from 50 hospitals

Objectives Diagnosing malnutrition in older individuals with excess weight is challenging, as commonly used tools rely on anthropometric measures such as body mass index (BMI) and calf circumference (CC), which can be affected by excess weight. To partially address this concern,...

Terminology for describing the 24-h cycle of physical activity, sedentary behaviour, and sleep: a scoping review

Abstract Background Physical activity, sedentary behaviour, and sleep are three behaviours which occupy the 24-h cycle and interact to influence a multitude of health outcomes. Different terms are currently used to describe these behaviours collectively (e.g., movement behaviours...

Role of atmospheric sulfate from industrial gypsum emissions in shaping soil solution chemistry and aluminum speciation along the soil profile

, indicating vertical redistribution driven by water fluxes. PCA identified sulfate as the primary variable governing the organization of soil solution chemistry along the soil profile. Overall, these findings demonstrate that continuous atmospheric sulfate deposition from indust...

Telephone versus in-person administration of the Early Childhood Development Index 2030: a crossover study, Brazil, Canada, India and Malawi.

Objective: To examine agreement between telephone and in-person administration of the Early Childhood Development Index 2030 (ECDI2030) survey. Methods: -tests and intraclass correlation coefficients. Findings: : -0.36), regardless of modality. However, pooled and stratified intr...
