Article Abstract
Incorporating bioactive substances into synthetic bioceramic scaffolds is challenging. In this work, oxygen-carboxymethyl chitosan (O-CMC), a natural biopolymer that is nontoxic, biodegradable and biocompatible, was introduced into magnesium potassium phosphate cement (K-struvite) to enhance its mechanical properties and cytocompatibility. This study aimed to develop O-CMC/magnesium potassium phosphate composite bone cement (OMPC), thereby combining the optimum bioactivity of O-CMC with the extraordinary self-setting properties and mechanical intensity of the K-struvite. Our results indicated that O-CMC incorporation increased the compressive strength and setting time of K-struvite and decreased its porosity and pH value. Furthermore, OMPC scaffolds remarkably improved the proliferation, adhesion and osteogenesis related differentiation of MC3T3-E1 cells. Therefore, O-CMC introduced suitable physicochemical properties to K-struvite and enhanced its cytocompatibility for use in bone regeneration.

Currently, no suitable parameter to predict the occurrence of azotaemic chronic kidney disease (CKD) after hyperthyroidism treatment in cats exists. The aim of this study was to evaluate various clinical and laboratory parameters as well as renal cortical thickness (assessed by ultrasound) as predictors of azotaemic CKD after radioiodine therapy (RAIT).Cats presented for RAIT (April 2021-April 2022) were prospectively enrolled.

Spider silk is highly attractive material because of its superior mechanical properties and excellent biocompatibility, enabling it to self-assemble into a wide range of morphological structures for drug delivery system. However, most spider silk particles developed as drug carriers are based on complex repetitive domains of spider silk proteins and exhibit relatively large particle sizes (> 300 nm), which limits their biomedical applications. In this study, we engineered a novel recombinant spider silk protein (NC-iRGD) by integrating terminal domains derived from major ampullate silk and the tumor-penetrating peptide iRGD.

Fumonisins, primarily produced by spp. and , are common contaminants in maize, cereal grains, and other processed and derived products, representing a significant risk to food safety and public health. This study presents the development and optimisation of a high-performance liquid chromatography method with fluorescence detection (HPLC-FLD) for the quantification of fumonisin B1 (FB1) and B2 (FB2) in various food matrices.

Purpose: Diabetic ketoacidosis (DKA) is a serious complication in pediatric patients with type 1 diabetes, requiring careful management of electrolyte imbalances, particularly for hypokalemia. This study evaluates the clinical outcomes of different potassium supplementation strategies during DKA treatment.
Methods: This retrospective cohort study analyzed pediatric DKA cases treated in a pediatric emergency department over a 13-year period.
Optimization of Hydroponic Wheat Sprouts as an Alternative Livestock Feed: Yield and Biochemical Composition Under Different Fertilization Regimes.

This study investigated the effects of macronutrient type and concentration on the biomass yield and biochemical composition of hydroponically grown wheat sprouts (HWS), with the aim of identifying fertilization strategies that optimize both productivity and feed quality. HWS were cultivated using a nutrient film technique over a 7-day period under controlled environmental conditions, with treatments including calcium nitrate (CN1-CN3), potassium phosphate (CP1-CP3), potassium sulfate (CK1-CK2), and a balanced NPK 20-20-20 fertilizer (NPK1-NPK3), each applied at three increasing concentrations. The quantitative parameters assessed included biomass yield per unit of dry seed (DP, kg kg) and dry matter content (DM, %), while qualitative traits included crude protein (CP), ether extract (EE), crude fiber (CF), and ash content.
