In this study, the total phenolic content (TPC), antioxidant activity, and free radical scavenging activities (FRSA) of 70 samples comprising honeybee products (honey, pollen, royal jelly, and propolis) and their mixtures were determined. The TPC was determined in accordance with the Folin-Ciocalteu method, antioxidant activity with phosphomolybdenum, and FRSA with the 1,1-diphenyl-2-picryl hydrazyl (DPPH) assays. Honeybee propolis showed the greatest TPC, antioxidant activity, and FRSA followed by pollen, honey, and royal jelly, respectively. A positive correlation was observed between TPC and antioxidant activity of honey, pollen and mixed samples (respectively, =0.91, =0.93 and =0.92) (<0.01). Similarly, honey and mixed samples exhibited positive correlations with TPC and FRSA (respectively, =0.98 and =0.92) (<0.01). It was concluded that honeybee products and their mixtures have antioxidant activity and FRSA and these effects may be attributed to their phenolic content.

Plastic pollution and global warming are widespread issues that lead to several impacts on aquatic organisms. Despite harmful studies on both subjects, there are few studies on how temperature increases plastics' adverse effects on aquatic animals, mainly freshwater species. So, this study aims to clarify the potential impact of temperature increases on the toxicological properties of polyvinyl chloride nano-plastics (PVC-NPs) in Nile tilapia (Oreochromis niloticus) by measuring biochemical and oxidative biomarkers.

Myofibrillar myopathy (MFM) is characterized by segmental disarray of myofibrils and ectopic accumulation of a protein called desmin. Previously thought to be a glycogen storage disease, MFM is now recognized as a stand-alone myopathy. Endurance Arabians with MFM usually present with exertional rhabdomyolysis (MFM-ER) at the end of races, elevated serum muscle enzymes, and myoglobinuria.

Background: Real-time and rapid detection of ingredients in food has important significance for food safety. However, traditional detection methods not only require bulky and costly instruments but also are often based on single-mode analysis, limiting their accuracy and applications in point-of-care testing. Herein, an integrated and miniaturized dual-mode device based on colorimetric and photoacoustic (PA) principles is developed, using Au@Ag nanoparticles (Au@AgNPs) as signal probe and ascorbic acid (AA) and ascorbate oxidase (AAO) as analytes.

Gastric cancer (GC) is a significant global health challenge, particularly in high-incidence regions like East Asia. Despite improvements in screening and treatment, the progressive nature of precancerous lesions-such as atrophic gastritis, intestinal metaplasia, and dysplasia-necessitates effective prevention strategies. This review evaluates the role of chemoprevention in GC, focusing on agents designed to target these precancerous lesions.

Alkaline stress impairs fish productivity and performance and, therefore, is considered one of the major challenges facing aquaculture. In this work, the effects of supplementing diets with camel whey protein hydrolysates (WPH) on growth, digestion, antioxidant capacity, and gene expression were investigated in Nile tilapia (Oreochromis niloticus) under alkaline stress. A total of 160 fish (16.
