Background Trace elements play a crucial role in fish nutrition, with zinc (Zn) being one of the most important ele ments. BIO-sourced zinc nanoparticles were synthesized using the green microalga Pediastrum boryanum (BIO-ZnNPs, 29.35 nm). 30 or 60 mg/ kg dry feed of the BIO-ZnNPs (BIO-ZnNPs30 and BIO-ZnNPs60) were mixed with the Nile tilapia (Oreochromis niloticus) basal diet and fed ...

It is unclear how fish in freshwater ecosystems are affected by the combined presence of microplastics (MPs) and anionic surfactant detergents. So, our investigations focus on the nephrotoxic effects of both Polyethylene microplastics (PE-MPs) and Sodium lauryl sulfate (SLS) in single or combined exposure on African Catfish (Clarias gariepinus). In the current study, rearing water of catfish (Clarias gariepinus) was ... Read more

Several aquatic arthropodan classes, including Arachnida, Crustacea, and Ostracoda can parasitize on fish and might cause discomfort or serious harm to their tissues. These organisms can parasitize fish through either obligatory, facultative, or opportunistic relationships according to their behavior or the surrounding conditions. Free-living arthropods may be induced to parasitize fish by various physiological, environmental, or biological stimuli. Some other ... Read more

Background: Oreochromis niloticus has great economic value and potential for farming and development. Transportation of fish was done for breeding or trading purpose and it is a challenging aspect of aquaculture. This study aimed to investigate the effect of transportation in freshwater and brackish water on the resistance of O. niloticus as well as transportation stress mitigation effect of NaCl. ...

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

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

The current study evaluated the potential ameliorative effect of a dietary immune modulator, Nannochloropsis oculata microalga, on the mercuric chloride (HgCl2)-induced toxicity of Nile tilapia. Nile tilapia (45–50 g) were fed a control diet or exposed to ¼ LC50 of HgCl2 (0.3 mg/L) and fed on a medicated feed supplemented with N. oculata (5% and 10% (50 or 100 g/kg ... Read more

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

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

_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
