The growing demand for sustainable solutions in agriculture, driven by global population growth and increasing soil degradation, has intensified the search for sustainable soil conditioners. This study investigated the impact of adding nanoclay (NC) and nano lignin (NL) to thermoplastic starch (TPS) on its physical, chemical, and thermal properties, its effectiveness as a soil conditioner, and its resistance to UV-C degradation. TPS nanocomposites were prepared with varying NC (3 %, 5 %, 7 %) and NL (0.

The study aimed to assess the impact of dietary supplementation with tannic acid on the growth, health, and survival of Oreochromis niloticus following exposure to Aeromonas hydrophila. A total of 320 fish were divided into 16 tanks and assigned to four treatment groups: feed with 0.2 % tannic acid (TA), 0.

Cellulose tosylate (MCC-Tos) is a key derivative for surface modification and a crucial precursor for cellulose compatibilization in click reactions, enabling its functionalization for advanced applications. Replacing tosyl groups with alkyne groups broadens cellulose's potential in biocompatible reactions, such as thiol-yne click chemistry and protein/enzyme immobilization. To achieve this, we optimized the heterogeneous synthesis of MCC-Tos using a Doehlert matrix statistical design, evaluating the influence and interaction of the reaction conditions.

Background: Microvascular decompression (MVD) is the gold-standard surgical treatment for cranial nerve compression disorders, including trigeminal neuralgia (TN), hemifacial spasm (HFS), and glossopharyngeal neuralgia (GPN). This review synthesizes historical milestones, recent advances, and evolving techniques in MVD, with a primary focus on these conditions.

Methods: A comprehensive literature review was conducted using databases such as PubMed, SpringerLink, Google Scholar, BioMed Central, Scopus, and ScienceDirect.

Paeniclostridium sordellii is responsible for severe infections in horses, cattle, and sheep, however, conventional vaccines exhibit limitations in production and immunogenicity. This study assessed the immunogenicity of a recombinant bacterin composed of a chimera (rQTcsHL) that combines segments from the lethal (TcsL) and hemorrhagic (TcsH) toxins in mice and sheep. Both immunized animal groups exhibited elevated levels of IgG, with the mice demonstrating moderate protection (<50 %) against lethal challenges, comparable to that of the conventional vaccine.
