Dissociation Between Instrumented Mobility and Self-Reported Function in Adults Aged 70 Years or Older After Unilateral Total Knee Arthroplasty: A Preliminary Longitudinal Study Using an Inertial Sensor and the WOMAC

Background and Objectives: Total knee arthroplasty (TKA) reliably reduces pain and improves self-reported function, yet objective mobility may remain impaired in older adults. We examined the relationship between inertial-sensor-based mobility and the Western Ontario and McMaster...

Soil-plant-animal properties and microbial reassembly distinguish cattle oral disease prevalence across converted Amazon pasture systems

Forest-to-pasture conversion can alter soil properties, forage composition, and microbial communities, but whether these changes are associated with bovine periodontitis remains unclear. We compared eight pasture systems in the Western Brazilian Amazon classified by high or low h...

Vocal repertoire and variability in the advertisement call of Ololygon goya Andrade, Santos, Rocha, Pombal & Vaz-Silva 2018 (Anura: Hylidae): influence of climatic and morphological attributes

Most anuran species exhibit complex vocal behavior, capable of producing a variety of sounds that are used, primarily, in the context of mating and resource defense. Understanding how acoustic traits vary among individuals and respond to climatic and morphological factors is fund...

Landscape genomics on Acrocomia aculeata trees aiming breeding selection

Abstract Acrocomia aculeata is a promising oil-producing palm whose breeding is constrained by its long juvenile period, high costs of phenotypic evaluations, and limited genomic resources. Here, we present an integrative framework combining landscape genomics and genomic selecti...

SGA-based volleyball teaching with explicit life skills instruction is associated with technical-tactical, psychosocial, and motivational improvements in school students

This quasi-experimental study examined whether a school volleyball unit based on the Step-Game-Approach model combined with explicit life skills teaching (SGA + LS) was associated with changes in technical-tactical performance, life skills, motivation, and perception of success....

Singular perturbations for superlinear problems in non-reflexive fractional Orlicz–Sobolev spaces

Abstract In this work, we investigate the existence and multiplicity as well as regularity of solutions for a huge class of concave–convex problems involving the fractional upper Phi $\Phi$ Φ -Laplacian operator in non-reflexive setting. The main difficulty arises from the lack o...

Bacillary hemoglobinuria in a dairy cow in Goiás State, Central-West Brazil, without demonstrable evidence of active fascioliasis

Abstract In a dairy herd in the state of Goiás, Central-West Brazil, a cow died following an acute illness characterized by jaundice and hemoglobinuria. Necropsy revealed jaundice, dark-red urine and dark-red discoloration of the kidneys, and a diffusely copper-colored liver with...

Nickel-Glycerolate/MOF-Based Electrode Materials for Energy Storage and Water-Splitting Applications

Abstract Herein, binary coordination compounds based on Ni-Gly/ZIF-67 and Ni-Gly/CoFe-ZIF-67 were employed as electrode materials for energy storage and water-splitting applications, respectively. The structure and morphology of the binary electrodes were characterized by XRD, XP...

Healthcare occupancy data as an early warning indicator of infectious disease surges in São Paulo

Early detection of infectious disease surges is critical for effective public health response, yet traditional surveillance systems often suffer from delayed reporting. Here, we investigate whether passively collected occupancy data from healthcare facilities can act as an early...

First Brazilian instrument for assessing patient engagement in patient safety: a cross-cultural adaptation and content validation study

Abstract Background Patient safety is highlighted as a global health challenge, requiring changes and the implementation of initiatives to minimize risks, prevent care failures, and avoid harm to patients. Patient engagement has been one of the most recommended strategies for imp...

From glow to risk: degree of exposure of Arctiinae moths (Lepidoptera: Erebidae) to light pollution in the Neotropics

Abstract The accelerated decline of insects is driven by anthropogenic pressures such as habitat loss, pesticide use, and climate change. Species vulnerability varies according to their exposure, sensitivity, and adaptive capacity to these threats. Artificial light at night (ALAN...

Association of Interleukin‐17F Polymorphisms (rs763780, rs9382084, rs2397084, and rs12203582) With Gastric Cancer Susceptibility According to Helicobacter pylori Infection Status

ABSTRACT Single nucleotide polymorphisms (SNPs) in the interleukin‐17F (IL‐17F) gene may modulate inflammatory responses, with distinct effects on inflammation and tumour progression. Helicobacter pylori infection, a Group 1 carcinogen, is strongly associated with gastric cancer...

Evaluation of Passiflora edulis Seed Extract and Piceatannol in Attenuating Hyperglycemia and Oxidative Stress Using Human and Nonhuman Antidiabetic Enzymes, Human Neutrophil Oxidative Burst, and Embryonic Zebrafish Hyperglycemia Model

Abstract Passiflora edulis seeds are frequently discarded as agro-industrial residues despite being a source of bioactive compounds such as piceatannol (PIC). Their valorization through ethanolic extraction aligns with circular economy principles and enables the investigation of...

Introducing Acid–Base Titration on Paper-Based Analytical Devices in a High-School Chemistry Laboratory for the Determination of Acetylsalicylic Acid

Abstract In this study, paper-based analytical devices (PADs) were used to introduce a simple, rapid, portable, and low-cost acid–base titration method in high school chemistry laboratories. Students performed conventional and paper-based titrations to determine the amount of ace...

Genetic Variant-based Machine Learning Prediction of Diabetic Nephropathy: A Pilot Study in Brazilian Patients

Abstract Purpose Diabetic nephropathy (DN) is a major microvascular complication of type 2 diabetes, where genetic predisposition significantly influences susceptibility. Genetic variants that exacerbate oxidative stress and endothelial injury can disrupt glomerular microvascular...

Interleukin-17RA polymorphisms rs887796 and rs1468488 are not associated with gastric cancer

Abstract Background Gastric cancer is a multifactorial disease in which Helicobacter pylori ( H. pylori ) infection plays a central carcinogenic role through inflammation mediated by cytokines, including interleukin-17 (IL-17). The IL-17RA receptor is a key component of this sign...

Identifying Co‐Expressed lncRNAs Correlated With Traits of Interest in an Animal Model for Metabolic Diseases in Humans

Nutrigenomics investigates how nutrients modulate gene expression. Among them, fatty acids (FA) play important roles in regulating gene transcription, while long non-coding RNAs (lncRNAs) may be associated with gene regulation and metabolic diseases. This study aimed to analyze t...

Iteration of Complexity and Asymptotic Analysis of Gradient-Type Methods with Non-monotone Line Search on Riemannian Manifolds

Abstract This paper investigates gradient-type methods for solving optimization problems on Riemannian manifolds. In this approach, we utilize a search direction based on the gradient direction and employ a general non-monotone line search scheme to determine the stepsize at each...

Multistability and global dynamics of orthogonally coupled von Mises trusses with unilateral contact

Abstract This work investigates the nonlinear dynamics of a system composed of two orthogonally coupled von Mises trusses connected through a unilateral elastic element. A discrete model is derived using an energy-based formulation, accounting for geometric nonlinearities and uni...
