Effects of Salts and Other Contaminants on Ciprofloxacin Removal Efficiency of Green Synthesized Copper Nanoparticles.

Ciprofloxacin (CIP), a broad-spectrum fluoroquinolone antibiotic, is commonly used in aquaculture to prevent and treat bacterial infections in aquatic animals. For this reason, aquatic environments contain CIP and its derivatives, which lead to the development of drug-resistant bacteria. In the present study, copper nanoparticles were prepared using extract (GME-CuNPs) as a reducing agent and evaluated for their CIP removal efficiency (CRE).

Modification of Polyethylene Glycol-Hydroxypropyl Methacrylate Polymeric Micelles Loaded with Curcumin for Cellular Internalization and Cytotoxicity to Wilms Tumor 1-Expressing Myeloblastic Leukemia K562 Cells.

Curcumin loaded in micelles of block copolymers of ω-methoxypoly(ethylene glycol) and N-(2-hydroxypropyl) methacrylamide modified with aliphatic dilactate (CD) or aromatic benzoyl group (CN) were previously reported to inhibit human ovarian carcinoma (OVCAR-3), human colorectal adenocarcinoma (Caco-2), and human lymphoblastic leukemia (Molt-4) cells. Myeloblastic leukemia cells (K562) are prone to drug resistance and differ in both cancer genotype and phenotype from the three mentioned cancer cells. In the present study, CD and CN micelles were prepared and their effects on K562 and normal cells were explored.

Effects of plant-based copper nanoparticles on the elimination of ciprofloxacin.

Ciprofloxacin (CIP) is frequently detected in the environment and causes the emergence of drug-resistant bacteria. High levels of CIP in the environment are also harmful to humans and animals. Therefore, effective elimination of CIP is required.

Masculinizing Effects of Chrysin-Loaded Poloxamer Micelles on Siamese Fighting Fish.

Siamese fighting fish () are freshwater fish that are commonly found in Thailand and other Southeast Asian countries. In the present study, chrysin-loaded polymeric micelles (CPs) were developed and investigated for the masculinizing effects, survival rate, growth indices, and toxicity on Siamese fighting fish. CPs were prepared using a poloxamer.

Investigation of antiaromatase activity using hepatic microsomes of Nile tilapia (Oreochromis niloticus).

Microsomal aromatase enzymes of humans and rats have been used in antiaromatase assays, but enzyme activity is species-specific. The current study extracted hepatic microsomes of Nile tilapia (Oreochromis niloticus) to investigate and compare the antiaromatase activity of chrysin, quercetin, and quercitrin. This activity was evaluated using a dibenzylfluorescein (DBF) assay.

Development of chrysin loaded poloxamer micelles and toxicity evaluation in fish embryos.

Poloxamer micelles promise safety and efficacy for many water insoluble drugs. Chrysin has been reported to have anticancer, anti-inflammatory, antioxidant, and anti-aromatase activities but its water insoluble properties limit its pharmaceutical application. In the present study, chrysin loaded poloxamer micelles were developed.

Analysis of the 5.8S rRNA and internal transcribed spacers regions of the variant Naegleria fowleri Thai strain.

The aim of this study was to analyze the internal transcribed spacers regions (ITS) of the of 5.8S ribosomal RNA (rRNA) gene of four isolants of Naegleria fowleri. Three of four Thai strains were isolated from patients and one from the environment.
