Dual-action oral platform for integrated systemic and gut-targeted treatment of acute kidney injury

Abstract Acute kidney injury (AKI) involves oxidative stress, inflammation, and metabolic toxin accumulation, leading to renal dysfunction and systemic metabolic disorders. Current treatments provide limited efficacy and fail to address the interplay between renal and intestinal pathologies. Here, we present a noninvasive dual-action oral platform that integrates systemic and gut-targeted therapeutic effects to restore homeostasis...

Optimality conditions and solution analysis at infinity for nonsmooth optimization problems

Abstract In this study, we investigate a nonsmooth and nonconvex optimization problem with an unbounded feasible set. Leveraging recent advancements in variational analysis at infinity, we establish novel necessary and sufficient optimality conditions formulated in terms of the normal cone and limiting subdifferentials at infinity. Moreover, by introducing newly defined sets, we analyze asymptotic conditions...

Integrin αvβ3 is a Potential Therapeutic Target in Cholangiocarcinoma

Abstract Cell surface receptors play vital roles in cancer growth and metastasis. Integrin αvβ3 is overexpressed in various cancer cells and interacts with different growth factors to stimulate cancer progression. Thyroid hormone binds to αvβ3 to activate signal transduction and cell proliferation. However, thyroxine (T4) deaminated analogue, tetraiodothyronine (tetrac), competes for the binding on integrin...

On Hermitian factorizations of matrices over division rings

Abstract  This paper investigates conditions under which a matrix over an involutory division ring can be expressed as a product of Hermitian matrices, and estimates the minimal length of such factorizations. Let D be a division ring with center F and involution ⁎. Among others, we prove the following results: (1) every non-invertible square matrix over D is the product of...

Optimization of sulfuric acid–catalyzed hydrolysis of paper waste sludge for bacterial cellulose biosynthesis: A sustainable approach to industrial waste valorization

Abstract Paper waste sludge (PWS) generated by the pulp and paper industry is a cellulose-rich residue that remains largely underutilized and presents disposal challenges. In this study, an integrated chemical–biological process was developed to valorize PWS into high-value bacterial cellulose (BC) through sulfuric acid–catalyzed hydrolysis followed by fermentation with Acetobacter xylinum. The hydrolysis step was statistically...

MTAS: A temporal-aware multiview graph attention framework for early rumor detection on social media

Abstract The rapid growth of information dissemination on social networks such as Facebook and Twitter, along with the widespread of mobile devices, has intensified the need for early yet accurate rumor detection methods. While existing hybrid machine learning models integrating natural language processing (NLP) and graph neural networks (GNNs) show promising results but often lack...

Printable TiO₂@g-C₃N₄ photoelectrodes for efficient water splitting

Abstract In this work, TiO2@g–C3N4 was synthesized and formulated as a novel ready-to-use screen-printable paste for water splitting applications. Various analytical methods were employed to examine the composition, morphological characteristics, and optical properties of the individual materials and the resulting heterojunction. Photoelectrochemical (PEC) water splitting was investigated under illumination of 100 mW cm-2 using linear chopped-light chronoamperometry...

Coupled Evolution of Local Stress and Strain-Induced Crystallization Near a Circular Defect in Stretched Natural Rubber

Abstract We investigate the coupled evolution of heterogeneous strain, crystallinity, and stress fields in natural rubber (NR) sheets containing a circular hole during uniaxial stretching, with a focus on how strain-induced crystallization (SIC) influences local stress concentration at structural discontinuities. By high-resolution digital image correlation, an empirical strain-crystallinity relationship and a hyperelasticity analysis firmly grounded...

Hydrate technology for water desalination in the Mekong Delta, Vietnam

Abstract Freshwater scarcity is a critical issue in Vietnam, particularly in the Mekong Delta, a densely populated region with an agriculture-based economy. This scarcity is largely driven by saltwater intrusion during the dry season, severely affecting both agriculture and the local economy. In response, advanced desalination technologies have been proposed. In this study, we investigated...

Simultaneous treatment and enrichment of total phosphorus from livestock sewage using hydrate technology

Abstract The presence of phosphorus in livestock sewage is a key factor that causes eutrophication and the degradation of ecological water quality. Cyclopentane (CP) hydrate-based water treatment technique was utilized for the efficient total removal of phosphorus in effluents. This study assesses the treatment effectiveness and enrichment potential of hydrate technology when applied to real-world samples, specifically livestock wastewater....
