Biochar-Based Materials from Plant Waste: Physicochemical and Structural Characteristics, Zearalenone Binding in Vitro

Contamination of feed with zearalenone (ZEN) poses a threat to animal and human health, which drives interest in low-cost sorbents derived from plant waste. For non-activated biochars, the properties that govern ZEN binding remain not fully studied. A hypothesis was proposed stat...

Non-isothermal Cold Crystallization as a Tool for Analysis of Crystal Nucleation: The Example of Polytetrahydrofuran

Abstract Polytetrahydrofuran (PTHF) was employed for analysis of the effect of heating rate q on the peak temperature of cold crystallization Tp and enthalpy of cold crystallization Δhcc to follow crystal nucleation. The isothermal increase of the number of nuclei in the highly s...

Lifestyle-Associated Biomarkers of Cellular and Whole-Organism Aging: A Practical Roadmap for Human Geroscience Trials

Aging is a multidimensional biological process that is not adequately captured by chronological age alone. Geroscience—the study of biological mechanisms that drive age-related functional decline and disease susceptibility—therefore requires biomarker frameworks that can identify...

Big Data Governance and Financial Support

Abstract A framework and a set of indicators developed for monitoring the management system and financing mechanisms for working with big data are presented. The framework includes two components covering the very management system for the development and the use of big data tech...

Enhancement of hippocampal synaptic AMPA receptor function by the antidepressant tianeptine and by opioid peptides

Management of major depressive disorder (MDD) with conventional therapeutics that enhance monoaminergic neurotransmission requires prolonged treatment prior to clinical benefit and a substantial proportion of patients show little or no improvement. Identifying alternative molecul...

Zoophycos–Skolithos Ichnofabric in Viséan Deposits of the South Tatar Arch: Cross-Cutting Relationships and Evidence of Marine Influence

Bioturbated Viséan sandstone–siltstone intervals of the South Tatar Arch have been interpreted as recording short-lived marine influence, but their ichnological basis has not been examined in detail. This study assesses the palaeoecological significance of a Zoophycos–Skolithos i...

Strategic development of IT business on no-code platforms: conceptualisation of the notion and transformation of the corporate IT function

The article offers a conceptualisation of the strategic development of IT business on no-code platforms and describes the accompanying transformation of the corporate IT function. By contrasting three research approaches to the notion of IT business – the product, functional, and...

Assessment of factors affecting the timeliness and quality of forensic medical examinations in cases of inadequate medical care provided to children

The duration and quality of forensic medical examinations are key indicators that determine the effectiveness of forensic expert institutions and, ultimately, impact the administration of justice and the protection of children's rights. The article presents the results of an asse...

Atlas of cell types and regulatory elements underlying human facial diversity

Abstract Human genetic diversity generates an astonishing variety of facial shapes, and craniofacial anomalies rank among the most common birth defects. Identifying the cellular mechanisms that mediate the genome’s influence on facial variation remains a challenge. Here we create...

Metagenomic and Metabolomic Signatures of Gut Microbiota After Helicobacter pylori Eradication Therapy Supplemented with Butyric Acid and Inulin: Observational Study

The long-term impact of eradication therapy for Helicobacter pylori on the gut microbiota is a subject of significant interest. To evaluate the influence of the bismuth-based quadruple H. pylori eradication therapy supplemented with butyrate and inulin on functional alterations w...

Supramolecular Organization of Copper-Coordinated Segmented Polyurethanes

Abstract The supramolecular organization in segmented polyurethanes modified with various copper-containing metal complexes was studied using the small-angle X-ray scattering method and atomic-force microscopy. It was found that in series of CuCl2—N,N'-diethylhydroxylamine (MCS s...

Multi-criteria kinetic modeling of kerogen hydrothermal conversion: assessing network complexity and model selection

The kerogen-rich oil shale deposits constitute a strategically vital unconventional resource base. However, suitable kinetic studies that represent the reactions for developing appropriate technologies are scarce. This study systematically evaluates the predictive accuracy of kin...

Lysozyme-Based Microspherical Particles for Delivery of Nalidixic Acid: Preparation, Composition Optimization, and Solubility Study

Abstract The development of effective delivery systems for poorly soluble pharmaceuticals remains a critical challenge in modern pharmaceuticals. This study explores the use of lysozyme, a biopolymer with unique immunological and stabilizing properties, as a matrix for creating a...

Highly Contiguous Is Not Chromosomally Accurate: Integrated Cytogenetic and Genomic Mapping in Two Turtle Genome

Abstract High-quality genome assemblies are essential for robust research across biological and medical fields. Assembly errors can have far-reaching consequences for downstream analyses, including gene annotation and the inference of synteny. In contrast to the rapid growth of g...

Сharacteristics of aquatic invertebrates in the upper basin of Bakhta River (Krasnoyarsk Krai, Tungus Plateau) in the context of the distribution of relict and Baikal species

Pioneering studies were conducted on zooplankton, meiozoobenthos and macrozoobenthos assemblages in mountain-type taiga rivers: the Bakhta, Surindakan and Maigungda, as well as in the Yenisei River at the confluence with the Bakhta River. The studied watercourses are oligotrophic...

ASSESSMENT OF BRAKING PERFORMANCE OF NON-AUTONOMOUS MOTOR-CAR ROLLING STOCK BASED ON THE METHOD OF ACCOUNTING FOR DESIGN PERFORMANCE OF BRAKING MECHANISMS

The study objective is to develop a method for assessing the design perfection of a braking mechanism as the basis for assessing the braking efficiency of non autonomous motor-car rolling stock. To implement this method, the maximum deviation of the average values of the normal f...

Strong coupling between RF photons and plasmons of electrons on liquid helium

Plasmons, arising from the collective motion of electrons, can interact strongly with electromagnetic fields or photons; this capability has been exploited across a broad range of applications, from chemical reactivity to biosensing. Recently, there has been growing interest in p...

Transcriptional and histopathological profiling of skeletal muscle in Bla/J mice at the stage of dysferlinopathy manifestation

Dysferlinopathy is a rare muscular dystrophy characterized by chronic muscle damage and ineffective regeneration. While late-stage morphological changes, such as fibroadipose replacement, are well described, the early molecular mechanisms driving muscle fiber loss and regenerativ...
