Elimination of Ni(II) from wastewater using metal-organic frameworks and activated algae encapsulated in chitosan/carboxymethyl cellulose hydrogel beads: Adsorption isotherm, kinetic, and optimizing via Box-Behnken design optimization.

The study investigated the enhancement of stability and efficacy in the removal of bivalent nickel ions (Ni(II)) by utilizing a cerium metal-organic framework (Ce-MOF) encapsulated within a food-grade algal matrix. This composite material is integrated into a dual-layer hydrogel containing chitosan and carboxymethyl cellulose. The enhancement of structural integrity in the final product can be attributed to the cross-linking process with epichlorohydrin, leading to the development of Ce-MOF-FGA/CMC-CS hydrogel beads.

Healthy Aging and the Gut Microbiome in People With and Without HIV.

Background: Aging-related comorbidities are more common in people with human immunodeficiency virus (HIV) compared to people without HIV. The gut microbiome may play a role in healthy aging; however, this relationship remains unexplored in the context of HIV.

Methods: 16S rRNA gene sequencing was conducted on stool from 1409 women (69% with HIV; 2304 samples) and 990 men (54% with HIV; 1008 samples) in the MACS/WIHS Combined Cohort Study.

Antimicrobial use in animal farms in Egypt: rates, patterns, and determinants.

Background: While antimicrobial use (AMU) in human healthcare has received significant attention as a key driver of antimicrobial resistance (AMR), less emphasis has been placed on AMU practices and attitudes in animal husbandry. To address this gap, this study examines the patterns and underlying drivers of AMU on animal farms.

Methods: A survey instrument was distributed to farm staff in 150 animal farms across 15 Egyptian governorates.

Mangiferin mitigates methotrexate-induced liver injury and suppresses hepatic stellate cells activation in rats: Imperative role of Nrf2/NF-κB/NLRP3 signaling axis.

Ethnopharmacological Relevance: Mangifera indica (family Anacardiaceae), often acknowledged as mango and renowned for being a plant of diverse ethnopharmacological background since ancient times, harbors the polyphenolic bioactive constituent, mangiferin (MNG). MNG is a major phytochemical of Mangifera indica and other plants with a wide range of reported pharmacological activities, including antioxidant, anti-inflammatory, neuroprotective and hepatoprotective effects. MNG has also been utilized in traditional medicine; it is reportedly a major bioactive element in over 40 polyherbal products in traditional Chinese medicine (TCM), and two prominent anti-inflammatory, immunomodulatory and antiviral Cuban formulations.

Synthesis of photo-responsive κ-carrageenan-based hydrogels for drug delivery application.

Natural polymer-based hydrogels may act as versatile platforms in controlled drug delivery. In this regard, photoactive κ-carrageenan (κ-Crg) hydrogels modified with cinnamate (CN) groups are developed for pH-sensitive release of drugs. κ-Crg-CN derivatives containing 17 %, 33 %, and 49 % cinnamate contents, named κ-Crg-CN1, κ-Crg-CN2, and κ-Crg-CN3, respectively, are prepared and cross-linked by UV-induced [2π + 2π] cycloaddition.
