Scientometric Update and Structured Synthesis of Microgreens Under Artificial Lighting: Trends and Reporting Gaps from 2022 to 2025

Microgreens have rapidly become a relevant topic in horticulture, controlled-environment agriculture, food quality and functional nutrition. Because artificial lighting is a central factor in indoor production, this study updated the scientometric panorama of microgreens research...

Landscape and mutational dynamics of G-quadruplexes across the complete human genome

Abstract Background G-quadruplexes (G4s) are alternative DNA structures with diverse biological roles, but their examination in highly repetitive parts of the human genome has been hindered by the lack of reliable sequencing technologies. Recent long-read based genome assemblies...

On linear equations over split-octonions

Over an algebraically closed field, we describe the affine varieties of solutions to the linear equations (ax)b=c and a(bx)=c over the split-octonions. We also determine the dimensions of the solution sets of arbitrary linear monomial equations in the split-octonions. Moreover, w...

The role of solid-state phase transformation mechanisms on the hydrogenation of multicomponent TiZrFeNi and Ni-Zr binary alloys

This study investigates solid-state phase transformations during hydrogenation of multicomponent TiZrFeNi and Ni-Zr binary alloys sharing the Ni 10 Zr 7 phase. The multicomponent alloy was designed using semi-empirical criteria and predicted by CALPHAD calculations. The phase equ...

Sliding Trajectories of Generic Inelastic Piecewise-Linear Dynamical Systems on the Torus

Abstract We consider piecewise smooth differential equations $$Z_{X_-X_+}$$ Z X - X + , where $$X_-$$ X - and $$X_+$$ X + are linear inelastic vector fields on $$\mathbb {R}^3$$ R 3 with the torus as the discontinuity manifold. Under suitable assumptions, we classify the tangency...

Multimodal Magnetic Resonance Imaging and Machine Learning Uncovers Distinct Progression Patterns in Friedreich Ataxia

Abstract Background Friedreich ataxia (FRDA) is a rare neurodegenerative disorder with heterogenous clinical progression, complicating prognosis and trial design. Neuroimaging offers objective biomarkers of disease progression, yet variability in progression patterns remains poor...

Differential Diagnosis of Mucopolysaccharidoses Types I, II , III , IVA , and VI Through Analysis of Leukocytic Inclusions

ABSTRACT Mucopolysaccharidoses (MPS) are lysosomal storage disorders characterized by the accumulation of glycosaminoglycans (GAGs), which can lead to cytoplasmic alterations in leukocytes. The objective of this study was to characterize leukocyte inclusions in patients with diff...

Bioactivity and nutritional profiling of underexplored unconventional food plants with potential for applications as functional foods

Abstract This study evaluated the bioactive and nutritional properties of six Amazonian unconventional food plants: Piper peltatum , Mansoa alliacea , Leuenbergeria bleo , Bidens bipinnata , Costus spiralis , and Urera caracasana . The phenolic compounds were identified and quant...

Solanum vegetables as potential neuroprotective functional foods in Alzheimer's disease management: A unifying mechanism

Alzheimer's disease (AD) is a multi-etiological neurological condition that requires a holistic therapeutic approach in its management. In view of this functional foods and nutraceuticals have become --promising candidates in AD research. This is because functional foods and nutr...

Can vision-language models estimate patient age? evidence from panoramic radiographs

Abstract Objective To explore the performance and limitations of three vision-language models (VLMs) in estimating chronological age from panoramic radiographs. Materials and Methods A sample of 140 panoramic radiographs from individuals aged 7 to 20 years was uploaded to three V...

A First-Principles Study of Surface-Dependent Synergy between H2O and O2 on Silver-Based Oxide Semiconductors

Abstract Silver-based ternary oxides, including Ag3PO4, β-Ag2MoO4, and the α- and γ-Ag2WO4 polymorphs, are promising photocatalysts for generating reactive oxygen species (ROS). In this work, density functional theory calculations were employed to disclose the atomic site-specifi...

Computational Design of Three-Dimensional Nitrogenated Holey Graphene Structures with Phase-Dependent Optoelectronic Properties

Abstract In this work, we propose and comprehensively characterize two novel three-dimensional nitrogenated holey graphene (3D-NHG) structures, designated as the α and β phases. These architectures are predicted through a computational protocol based on the controlled compression...

Methodological Quality and Overlap of Systematic Reviews Comparing Carotid Endarterectomy versus Carotid Artery Stenting in Symptomatic Contralateral Carotid Occlusion: An Overview of Reviews

Background: Symptomatic contralateral carotid occlusion (CCO) is considered a high-risk scenario for carotid revascularization, yet the comparative evidence for carotid endarterectomy (CEA) versus carotid artery stenting (CAS) is largely derived from observational data and repeat...

Screening of Brazilian Isolated Yeasts Reveals Multiple Potential Chassis for Industrial Biotechnology

ABSTRACT The future of sustainable industrial biotechnology relies on microbial hosts that can thrive where conventional strains fail. Although Saccharomyces cerevisiae remains the dominant industrial yeast, its metabolic constraints and stress sensitivity highlight the need for...

Integrating menopausal neurocognitive and psychosocial dynamics into economic behavior: the Behavioral Finance–Menopausal Cognition (BF-MC) Model (MARiE WP2A study)

Objective: Traditional behavioral finance—which examines how cognitive biases, emotions, and context shape economic decision-making— often assumes cognitive stability, rationality, and consistent risk evaluation, based largely on male-dominated samples. Emerging evidence from the...
