Medical prospects of cryptosporidiosis control using biofabricated nanoparticles loaded with extracts by .

Background And Aim: Global efforts are continuing to develop preparations against cryptosporidiosis. This study aimed to investigate the efficacy of biosynthesized loading oil extract on new zinc oxide nanoparticles (ZnONPs shorten to ZnNPs) and silver nanoparticles (AgNPs) as alternative treatments for experimental infection in rats.

Materials And Methods: Oil extract was characterized by gas chromatography-mass spectrometry, loaded by on ionic-based ZnO and NPs, and then characterized by transmission electron microscopy, scanning electron microscopy, and X-ray diffraction.

Leaves: Polyphenolic Profile, Cytotoxicity, and Antioxidant Evaluation.

This study aimed to investigate the chemical composition of leaves and evaluate the antioxidant and antitumor effects of the total extract and its major metabolites. Four assays were used to determine the antioxidant activity, including radical scavenging abilities of 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS), radical cation, and ferric-reducing power. Additionally, vincristine was used as a reference medication to examine the anticancer activity on Ehrlich aesthete carcinoma cells (EACC).

A Comparative biochemical study on two marine endophytes, Bacterium SRCnm and Bacillus sp. JS, Isolated from red sea algae.

Two marine endophytic bacteria were isolated from the Red Sea algae; a red alga; Acanthophora dendroides and the brown alga Sargassum sabrepandum. The isolates were identified based on their 16SrRNA sequences as Bacterium SRCnm and Bacillus sp. JS.
