Rhazya stricta, a perennial shrub native to the Middle East and South Asia, has been used in traditional medicine for various therapeutic purposes, including antimicrobial action. The current study aimed to compare the antifungal properties of 96% and 50% ethanolic extracts of R. stricta leaves and their biogenic silver nanoparticles (AgNPs).

Background: Denture stomatitis, frequently encountered, is generally addressed symptomatically, with limited exploration of preventive approaches involving antifungal medicinal plants.

Objective: This study assessed the impact of Artemisia sieberi extracts on the candida growth of conventional and digitally processed acrylic materials.

Method: Thirty acrylic resin discs (3 mm thickness × 10 mm diameter) were prepared by conventional or CAD/CAM technology (milling and 3D printing).

One of the most promising, non-toxic, and biocompatible developments for many biological activities is the green synthesis of nanoparticles from plants. In this work, we investigated the antifungal activity of silver nanoparticles (AgNPs) biosynthesized from Rhazya stricta aqueous extract against several plant pathogenic fungi. UV-visible spectroscopy, Zeta potential analysis, Fourier-transform infrared spectroscopy (FTIR), and transmitted electron microscopy (TEM) were used to analyze the biosynthesized AgNPs.

Currently, the bioremediation of petroleum hydrocarbons employs microbial biosurfactants because of their public acceptability, biological safety, and low cost. These organisms can degrade or detoxify organic-contaminated areas, such as marine ecosystems. The current study aimed to test the oil-biodegradation ability of the fungus , which was isolated from contaminated soil samples in Riyadh, Saudi Arabia.

The green silver nanoparticles (green AgNPs) exhibit an exceptional antimicrobial property against different microbes, including bacteria and fungi. The current study aimed to compare the antifungal activities of both the crude aqueous extract of or different preparations of green AgNPs biosynthesized by mixing that aqueous extract with silver nitrate (AgNO). Two preparations of the green AgNPs were synthesized either by mixing the aqueous extract of  with silver nitrate (AgNO) (normal AgNPs) or either irradiation of the AgNPs, previously prepared, under Co γ-ray using chitosan (gamma-irradiated AgNPs).

Background: Candidiasis infection is associated with high morbidity and mortality. Fungicidal resistance of some commercially used fungicides ascended the need for a naturally effective alternative. The current study aimed to evaluate the fungicidal activity of Vitex agnus-castus extracts in vitro against some Candida species.

Grape seed extract (GSE) is a natural source of polyphenolic compounds and secondary metabolites, which have been tested for their possible antimicrobial activities. In the current study, we tested the antibacterial and antifungal activities of aqueous GSE and the biosynthesized silver nanoparticles loaded with GSE (GSE-AgNPs) against different pathogens. The biosynthesized GSE-AgNPs were assessed by UV spectroscopy, dynamic light scattering (DLS), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), and gas chromatography/mass spectrometry (GC/MS).

The green biosynthesis of nanoparticles by plant extracts is an attractive and promising technique for medicinal applications. In the current study, we chose one of the daisy plants, (which grows in the Najd region, Saudi Arabia), to investigate its anti-microbial efficacy, in combination with silver nanoparticles. The biosynthesized nanoparticles were evaluated for antibacterial activity against (Gram-positive), and (Gram-negative) using the disc diffusion method, while the antifungal activity was assessed against The potential phytoconstituents of the plant extracts were identified by Fourier-transform infrared spectroscopy (FT-IR) techniques, the Field emission scanning electron microscopy (FE-SEM), Chromatography/Mass Spectrometry (GC-MS) techniques, and Zeta potential analysis.

This study was designed to investigate the potential defensive strategy of Sana Makki extract (SME) against Cd-induced in vivo nephrotoxicity and its underlying mechanisms. Male albino rats were used in a thirty days study comparing control, SME-treated, CdCl2-treated, and combined SME and Cd treatment. Pre-treatment with SME significantly reduced serum kidney biomarkers (urea and creatinine), the concentration of renal KIM-1, and kidney index values.
