Differential stoichiometric responses of tolerant and susceptible sugarcane cultivars to silicon under drought and bacterial leaf scald

Sugarcane production is frequently impacted by the simultaneous occurrence of water deficit and diseases such as leaf scald, caused by Xanthomonas albilineans . These stresses can disrupt water relations, nutrient balance, and biomass production. Silicon (Si) has been reported to...

A Cyber-Physical framework for Energy-Aware distributed optimization of 6-DOF robotic manufacturing cells via hybrid bioinspired metaheuristics

Abstract Energy-aware coordination is a fundamental cornerstone for the future of autonomous Cyber-Physical Systems (CPS). This work proposes a novel distributed CPS framework to address the decoupling between high-level coordination of autonomous agents and the nonlinear dynamic...

Barriers and opportunities in waste electrical and electronic equipment management in Brazil and Colombia: Insights from recycling companies and cooperatives

This study investigates the challenges and institutional dynamics of waste electrical and electronic equipment (WEEE) management in Brazil and Colombia through the perspectives of recycling companies and cooperatives. A qualitative research approach was employed using semi-struct...

Adaptive caste allocation modulated by resource distance in Pheidole oxyops

Abstract Caste deployment in social insects reflects trade-offs between resource profitability and spatial costs. We examined how Pheidole oxyops allocates minor and major workers when foraging on carbohydrate- (honey) and protein-rich (sardine) baits placed at two distances (1 m...

Machine learning survival models for colorectal cancer: advantages of random survival forests over classification algorithms

Colorectal cancer remains a major cause of cancer-related mortality worldwide, motivating the development of accurate prognostic models. Despite advances in machine learning for survival prediction, a common practice in the literature reformulates time-to-event outcomes as binary...

P1.002. Twenty Years Follow-Up in Barrett's Esophagus: Does Fundoplication Demonstrate Superiority in the Comprehensive Long-Term Control of the Disease?

Abstract Topic Benign Disease: Barrett’s Esophagus: Pathology and Pathophysiology; Non-invasive Neoplasia Background The study analyzed the long-term evolution of Barrett's Esophagus (BE) and the effectiveness of clinical and surgical treatments for Gastroesophageal Reflux Diseas...

Cation-aromatic nitrogen interaction as a design principle for sodium deep eutectic electrolytes

We report a combined experimental and ab initio molecular dynamics investigation into the role of nitrogen hybridization (sp2 vs sp3) and ring aromaticity in the sodium-based deep eutectic electrolyte formation and their potential use in sodium-ion battery electrolytes. Mixtures...

Nocturnal to diurnal switches of tuco-tucos (Ctenomys coludo) in semi-natural burrow systems inside the laboratory

Although many species are classified as strictly diurnal or nocturnal, the temporal distribution of daily activity can be flexible for several species. The subterranean rodent tuco-tuco ( Ctenomys coludo) presents this flexibility, switching from diurnality to nocturnality when t...

Impact of chronic doxycycline treatment in a mouse model of tauopathy

Tauopathies are neurodegenerative disorders characterized by the accumulation of hyperphosphorylated tau, leading to synaptic dysfunction, neuroinflammation, and both cognitive and motor impairments. Doxycycline (Doxy), a tetracycline antibiotic commonly used to treat bacterial i...

The metabokine β-aminoisobutyric acid mediates exercise performance and skeletal muscle adaptation through a PGC1α-BAIBA-PPARδ axis

Abstract Exercise orchestrates an interorgan communication network, in which skeletal muscle releases signaling molecules known as myokines that contribute to exercise training-induced adaptations. We identified the muscle-derived metabolite beta-aminoisobutyric acid (BAIBA) as a...

Caracterização da paisagem sensorial dos cafés de origem brasileiros: sustentabilidade, recursos naturais e expressão territorial da qualidade

Produtos agroalimentares associados à origem têm sua qualidade e reputação construídas pela interação entre território, recursos naturais, práticas produtivas e processos de transformação, relação particularmente relevante para o café. Esta pesquisa investiga como sustentabilidad...

Variation in apparent wood density of Tachigali vulgaris as affected by tree diameter, height, forking, and soil conditions in Amazonian plantations

Abstract Tachigali vulgaris has potential for energy purposes in the Amazon, but the relationship between several silvicultural factors and wood quality requires further investigation. This study evaluated the variation in the apparent density of T. vulgaris wood in two pure plan...

A communication and messaging framework to increase public awareness of ultra-processed foods in Australia

Abstract Background Evidence of the health, environmental, and broader societal impacts of ultra-processed foods (UPFs) is rapidly accumulating, yet public awareness remains limited. This study aimed to develop a communication and messaging framework to increase public awareness...

Light-curing performance of dual-cure and preheated luting materials under simulated restoration thicknesses: an in vitro study

Increased restoration thickness may reduce light transmission and compromise the light-curing performance of luting materials. Although preheated resin-based composites have been proposed as an alternative to conventional resin cements, their behavior under limited light availabi...

cAmbly, a peptide derived from the star tick Amblyomma sculptum salivary gland transcriptome, attenuates inflammatory pain by activating endogenous opioid pathways

Pain affects more than 1.5 billion people worldwide and remains a leading cause of disability, but currently available analgesics often have limited efficacy and significant adverse effects. In this context, bioactive molecules derived from animal venoms and secretions have emerg...

Reduced IP6K levels impair life-cycle transitions and intracellular development of Trypanosoma cruzi within human cardiomyocytes

Trypanosoma cruzi is the etiological agent of Chagas disease (CD). During its life cycle, T. cruzi undergoes several key differentiation processes that are essential for its survival. The precise mechanisms that regulate these processes remain elusive, and any interference in thi...

Functional neurological disorder: characterization, diagnosis, and outcome predictors in a Brazilian cohort

Abstract Functional neurological disorder (FND) is a prevalent, disabling neuropsychiatric condition recognized as a distinct clinical entity characterized by positive neurological signs. Despite growing international research, Brazilian data on this disoder remain scarce and pre...
