ATR-FTIR Spectroscopy Combined with Machine Learning Enables Detection of Schistosomiasis-Associated Biochemical Signatures in Human Serum

Abstract Schistosomiasis, caused by Schistosoma mansoni, remains a major public health burden in endemic regions, demanding rapid and reliable diagnostic strategies. Here, we report a label-free diagnostic platform based on attenuated total reflectance Fourier transform infrared...

Phytochemical Screening and Protective Effects of Hancornia speciosa Leaf Extract Against Fatty Acid-Induced Lipotoxicity in HepG2 Cells

Hepatic steatosis is the hallmark of metabolic dysfunction-associated steatotic liver disease (MASLD), the most prevalent chronic liver disease worldwide. Lipotoxicity, resulting from excessive accumulation of fatty acids and bioactive lipid intermediates, is associated with incr...

Association between bedside oral health status and severe acute respiratory syndrome in hospitalized adults: a cross-sectional study

Hospitalized patients may experience oral health deterioration, particularly during acute respiratory illness. This study investigated the association between bedside oral health status and severe acute respiratory syndrome (SARS) in hospitalized adults. This cross-sectional stud...

Laminin-Derived Peptides and Isoforms: A Multifaceted Review of Their Roles in Cancer, Neurodegeneration, Inflammation, Tissue Regeneration, and Exercise Physiology

Background: Laminins are heterotrimeric basement membrane glycoproteins whose chain composition, molecular processing, receptor engagement, and cellular source determine their biological effects. Methods: We conducted an integrative narrative search of PubMed and manually screene...

Electrochemical characterization of laser-induced graphene electrodes and performance comparison to glassy carbon electrodes

Abstract Laser-induced graphene (LIG) has emerged as a versatile and high-performance carbon material in electroanalysis; however, the fundamental origins of its performance remain insufficiently clarified. Here, we systematically compare the electrochemical response of LIG elect...

Organic Matter Quality and Microbial Activity in Soils Managed With Brachiaria Succession

ABSTRACT Background Although succession systems and brachiaria improve soil quality, gaps remain in microbial community dynamics, activity, and soil organic matter stocks. Methods The objective was to evaluate the carbon (C) and nitrogen (N) stocks of soil organic matter fraction...

Comparative efficacy of platelet-rich fibrin protocols for alveolar ridge preservation: a systematic review and network meta-analysis

Abstract Objectives This systematic review and network meta-analysis (NMA) aimed to evaluate the effects of platelet-rich fibrin (PRF) in alveolar ridge preservation (ARP), as well as to compare and rank different PRF protocols according to their relative effectiveness. Methods E...

The Gemological Chameleon: Andalusite, Pleochroism, and the Problem of Gemstone Identity

Gemstones are commonly described according to their apparent color, yet in strongly pleochroic materials this visual attribute may vary systematically with crystallographic orientation, optical path length, cutting geometry, illumination, and viewing conditions. Andalusite provid...

Noninvasive or minimally invasive neuromodulation in animal models of acute ischemic stroke: A systematic review and meta‐analysis

Abstract Background Neuromodulation therapy has emerged as a potential brain cytoprotective strategy in the hyperacute phase of ischemic stroke (IS). This systematic review aimed to evaluate the cytoprotective effects of neuromodulation in animal models of IS. Methods A systemati...

The Oceanic Signature in Diamond: From Hydrothermal Alteration to Defect Architecture

Diamonds provide exceptionally durable records of geological processes occurring within Earth’s mantle, preserving information through mineral and fluid inclusions, isotopic compositions, growth structures, impurities, and lattice defects. Increasing evidence demonstrates that al...

Transformational leadership for environmental sustainability (TLES)

Purpose This study aims to adapt and expand the scale developed by Robertson (2018) to assess perceptions of Transformational Leadership for Environmental Sustainability (TLES). Design/methodology/approach To achieve this, 21 items were constructed using a five-point Likert scale...

Proteoglycans and Biomineralization of Bone and Dentin

Although many advances have been made during the last six decades, the controlled processes by which vertebrate hard tissues acquire, organize, and maintain their mineral component remain only partially understood. Mineralized tissues can be classified into two categories based o...

Intersectional racial and gender inequalities in food insecurity across socioeconomic conditions among undergraduate students: a cross-sectional study

Food insecurity is a key social determinant of health and reflects structural social inequities. In this study we examined sociodemographic and economic factors associated with food insecurity among undergraduate students, with particular emphasis on the intersections of race, ge...

Performance measurement and cross-functional cooperation: serial mediation of reciprocity and commitment

Purpose In social exchange theory (SET), intraorganizational social relationships are formed with the expectation of reciprocal benefits, reinforced by the support and efforts of those involved. This study aims to examine the serial mediation of reciprocity and commitment in the...

Histological reorganization and spatiotemporal distribution of cell wall epitopes during somatic embryogenesis in oil palm (Elaeis guineensis Jacq.)

Abstract Somatic embryogenesis is a key strategy for the clonal propagation of elite oil palm ( Elaeis guineensis Jacq.) genotypes. Although several protocols have been established, the structural aspects underlying the induction of embryogenic callus in this species remain unkno...

Efficient speech denoising using CleanUNet optimized with Mamba and hybrid spectral loss

Abstract Speech enhancement aims to recover clean speech from signals degraded by noise and adverse acoustic conditions, such as background interference and echo. CleanUNet has emerged as an effective solution for causal speech denoising, but its high computational demands limit...

Coding for sustainability? Investigating how sustainable practices emerge in software development

Abstract This study investigates the adoption of sustainable practices in software development through a mixed-method approach that integrates quantitative and qualitative analyses. Grounded in the best practices proposed by the Green Software Foundation (GSF), a research instrum...

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...
