Article Abstract
polysaccharides (SFPs) are acidic polysaccharides that possess significant medicinal and commercial potential. This review aims to summarize recent advances in the structure, extraction methods, and diverse biological activities of SFPs, including their antioxidant, antitumor, immunomodulatory, antiviral, intestinal flora-regulating, and anti-diabetic properties. The key findings reveal the complex composition of polysaccharides, highlighting alginic acid, fucoidan, and laminaran as the primary constituents, and detailing their structural features. At the same time, the characteristics as well as the advantages and disadvantages of hot water extraction, acid extraction, alkali extraction, ultrasonic extraction, microwave extraction, and enzyme extraction were systematically compared. Finally, this review concludes by emphasizing the necessity for further research to elucidate the structure-function relationships of SFPs, optimize their extraction techniques, and provide a theoretical foundation for subsequent studies.

Incorporation of madımak (Polygonum cognatum Meissn.) leaf powder into gluten-free bread formulations: Evaluation of their nutritional, antidiabetic, color, bioactive, textural, and sensory properties.
J Sci Food Agric
September 2025
Department of Nutrition and Dietetics, Hamidiye Faculty of Health Sciences, University of Health Sciences, Istanbul, Türkiye.
Background: This study aimed to develop gluten-free bread from chickpea flour by incorporation of varying levels (0 (B-C), 2.5 (B-1), 5 (B-2), and 10 g kg (B-3)) of madımak leaf powder (MLP), and to investigate its effect on physicochemical and bioactive properties, glycemic index, texture, and sensory attributes.
Results: Moisture ranged from 229 (B-3) to 244 g kg (control), while ash content increased with MLP, reaching 47 g kg in B-3 compared to 15.
Key locations of oxidative damage in human hair keratins after heat and ultraviolet light exposure.
Int J Cosmet Sci
September 2025
Smart Foods and Bioproducts, AgResearch, Lincoln, New Zealand.
Objective: This study investigated the locations of amino acid modifications within two major human hair keratins (Type I K31 and Type II K85) with probable implications for protein and hair structural component integrity. The particular focus was on cysteine modifications that disrupt intra-protein and inter-protein disulphide bonds.
Methods: Human hair was exposed to accelerated, sequential heat or UV treatments, simulating effects resulting from the use of heated styling tools and environmental exposure over a time frame approximating one year.
Minimizing Ionic Interference: An APCI-MS Strategy for Real-Time Reaction Monitoring in Ionic Liquids.

Ionic liquids (ILs) are a class of organic salts with melting points below 100°C. Owing to their unique chemical and physical properties, they are used as solvents and catalysts in various chemical transformations, progressively replacing common volatile organic solvents (VOCs) in green synthetic applications. However, their intrinsic ionic nature can restrict the use of mass spectrometric techniques to monitor the time progress of a reaction occurring in an IL medium, thus preventing one from following the formation of the reaction products or intercepting the reaction intermediates.

Introduction: We compared and measured alignment between the Health Level Seven (HL7) Fast Healthcare Interoperability Resources (FHIR) standard used by electronic health records (EHRs), the Clinical Data Interchange Standards Consortium (CDISC) standards used by industry, and the Uniform Data Set (UDS) used by the Alzheimer's Disease Research Centers (ADRCs).
Methods: The ADRC UDS, consisting of 5959 data elements across eleven packets, was mapped to FHIR and CDISC standards by two independent mappers, with discrepancies adjudicated by experts.
Results: Forty-five percent of the 5959 UDS data elements mapped to the FHIR standard, indicating possible electronic obtainment from EHRs.
Genetic Association of Lipids and Lipid-Lowering Drug Target Genes With Atopic Dermatitis: A Drug Target Mendelian Randomization Study.
Health Sci Rep

Department of Dermatology the Union Hospital, Fujian Medical University Fuzhou People's Republic of China.
Background And Aims: Several observational studies have reported inconsistent associations between dyslipidaemia, stains use and atopic dermatitis (AD). Nevertheless, the available data on the effects of -C-lowering as well as TG-lowering drugs remain inconclusive and limited. The aim of this study was to evaluate the causal association of lipid traits and long-term use of lipid-lowering drugs on AD risk.
