Dietary microalgal-fabricated selenium nanoparticles improve Nile tilapia biochemical indices, immune-related gene expression, and intestinal immunity
Background Feed supplements, including essential trace elements are believed to play an important role in augmenting fish immune response. In this context, selenium nanoparticles (SeNPs) in fish diets via a green biosynthesis strategy have attracted considerable interest. In this investigation, selenium nanoparticles (SeNPs, 79.26 nm) synthesized from the green microalga Pediastrum boryanum were incorporated into Nile tilapia diets to explore ... Read more

Self‑assembling Organogels Loaded with Tenoxicam for Local Intensive Pain and Inflammation Cure: In Vitro and In Vivo Correlation
Due to tenoxicam (TX)’s poor aqueous solubility (0.072 mg/ml), it is poorly absorbable in the GIT, and the long-term oral administration of TX may cause severe GIT disturbances. Topical administration of TX can help in bypassing the GIT adverse effects. Therefore, in the present work, we constructed different pluronic/lecithin organogels (PLOs) for topical delivery of TX. PLO was constructed simply ... Read more

Recent Advances in the Pharmaceutical and Biomedical Applications of Cyclodextrin-Capped Gold Nanoparticles
The real problem in pharmaceutical preparation is drugs’ poor aqueous solubility, low permeability through biological membranes, and short biological t1/2. Conventional drug delivery systems are not able to overcome these problems. However, cyclodextrins (CDs) and their derivatives can solve these challenges. This article aims to summarize and review the history, properties, and different applications of cyclodextrins, especially the ability of ... Read more

Protective effect of chitosan and chitosan nanoparticles on dioxin induced haematotoxicity and nephrotoxicity in male albino rats
Chitosan (CH) is a natural product produced from the shells of crustaceans. Both CH and Chitosan nanoparticles (CHNPs) have recently been used in various pharmaceutical and biomedical applications. The present study aimed to evaluate the potency of chitosan or chitosan nanoparticles in reducing the negative effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)- induced haematotoxicity and nephrotoxicity in albino rats. Methods: Twenty adult male ... Read more

Nutritional and immunological evaluation of Nannochloropsis oculata as a potential Nile tilapia-aquafeed supplement.
_Nannochloropsis oculata_ (_N. oculata_) is a marine microalga containing bioactive compounds and a high omega-3 polyunsaturated fatty acid (ω-3 PUFAs). Therefore, it is very promising for nutraceutical and the functional food industry applications. Three groups of Nile tilapia (forty-five fish/group) were fed on basal diets or diets containing 5% (N5) or 10% (N10) of the microalga _N. oculata_ for seven ... Read more
