Chemical Fingerprinting for Authentication and Compositional Characterization of Cocos nucifera Bee Pollen

Abstract Bee pollen produced by Apis mellifera is formed by the agglutination of floral pollen grains with nectar and bee secretions. Monofloral or dominant bee pollen generally exhibits a more consistent chemical composition and quality. In this study, coconut (Cocos nucifera) b...

Enhanced Antibacterial Activity of Lippia grata Essential Oil by Nanoencapsulation

Abstract Background Nanoencapsulation of essential oil with polysaccharides improves the antimicrobial property by reducing the essential oil volatility and imprinting a synergic effect from the polyelectrolyte. This was investigated for Lippia grata essential oil encapsulated in...

Zirconium Dioxide Nanoparticles in Bone Tissue Engineering: Recent Advances, Biological Interactions, and Future Perspectives

Bone defects from trauma, tumor resection, infection, and degenerative disease remain a large clinical problem, and the grafting strategies used to treat them still carry familiar limitations: donor-site morbidity for autografts, variable integration and supply constraints for al...

Individual Differences in Self-Regulation Do Not Predict Firearm Skill Acquisition During Police Training: A Longitudinal Study of 205 Trainees

Police firearm training requires perceptual discrimination, decision-making, speed–accuracy control, and technical motor execution under institutional evaluation. This retrospective longitudinal study examined whether self-regulation-related psychological characteristics predicte...

Beyond financial literacy: the complementary role of self-control in the saving behaviour of family farmers

Purpose This study investigates the relationship between financial literacy and saving behavior among family farmers associated with cooperative organizations, examining whether self-control mediates this relationship within the framework of Social Cognitive Theory (SCT). Design/...

Monotonicity of the Period Function in Planar Separable Hamiltonian Systems: An Extension of Chicone’s Criterion

Abstract We investigate the monotonicity of the period function associated with planar Hamiltonian systems of the form $$H(x,y)=F(x)+G(y),$$ H ( x , y ) = F ( x ) + G ( y ) , where $$G$$ G is an even function. We derive explicit sufficient conditions, expressed solely in terms of...

Ultrasonographic and Thermographic Evaluation in Brachycephalic Dogs Before and After Physical Exercise in the Brazilian Northeast Semi-Arid Region

Brachycephalic dogs are predisposed to respiratory and thermoregulatory impairment, which may become evident during physical exertion. This study evaluated thermal and pulmonary ultrasonographic responses to standardized submaximal treadmill exercise in 41 clinically healthy brac...

Does Adding Mindfulness to Instability Resistance Training Enhance Dual-Task Mobility and Fall-Related Outcomes in Older Adults with Motoric Cognitive Risk Syndrome? A Randomized Controlled Trial

Background Older adults with motoric cognitive risk syndrome (MCR) exhibit impairments in dual-task mobility. Non-pharmacological interventions, such as physical exercise and cognitive strategies, have been proposed to mitigate physical and cognitive decline. However, the effecti...

Seasonal dynamics of coffee leaf rust in highland areas in the Brazilian Northeast and its management using fungicides and resistant genotypes

Abstract In the state of Pernambuco, Brazil, coffee has been grown in highland areas, whose climatic conditions differ from other typically producing regions. Despite the large number of small coffee producers and the production potential, there is no information on coffee leaf r...

Antimicrobial, antibiofilm, and molecular docking evaluation of silver nanoparticles biosynthesized from Ocimum campechianum against Staphylococcus spp

Abstract Antimicrobial resistance and the overuse of antimicrobials have driven the search for innovative therapies, particularly those based on natural compounds and medicinal plant derivatives, aiming to develop new drugs. This study aimed to investigate the antimicrobial and a...

Mango peel flour (Mangifera indica) as a source of antioxidants and dietary fiber in goat meat sausages

Abstract Lipid oxidation is a major cause of quality deterioration in meat products, while dietary fiber is scarce in these foods. This study evaluated the effects of mango peel flour (MPF), a natural source of antioxidants and dietary fiber, on the quality characteristics of goa...

Assessing Water and Sediment Contamination in the Sub-Middle São Francisco River (Brazil): Combining Physicochemical Analyses, Trace Metals, and Allium cepa L. Ecotoxicity

The Sub-middle São Francisco River (Northeast Brazil), a key water resource for regional socioeconomic development, is increasingly threatened by urban, industrial, and intensive irrigated agricultural activities. This study aimed to assess physicochemical parameters, nutrient an...
