Optimization of Green Synthesis Formulation of Selenium Nanoparticles (SeNPs) Using Peach Tree Leaf Extract and Investigating its Properties and Stability.

Background: Selenium nanoparticles (SeNPs) are highly sought after in diverse industries for their distinct properties and advantages. SeNPs can be synthesized via several methods, including the use of microwave, bain-marie, autoclave, and heater.

Objective: The objective is to optimize the SeNP synthesis formulation, emphasizing stability, concentration, particle size minimization, and uniformity using central composite design.

Superparamagnetic MnFe alloy composite derived from cross-bindered of chitosan/rice husk waste/iron aluminate spinel hercynite for rapid catalytic detoxification of aflatoxin B1: Structure, performance and synergistic mechanism.

The contamination of foodstuffs with aflatoxins B1 (AFB1) as carcinogen/mutagens toxin produced by Aspergillus fungi that are a major threat to the economy, safe food supply, and human health. To, we present a facile wet-impregnation and co-participation strategies for the construction of a novel superparamagnetic MnFe biocomposite (MF@CRHHT), in which dual metal oxides MnFe were anchored in/on agricultural/forestry residues (chitosan/rice husk waste/hercynite hybrid nanoparticles) and applied for rapid AFB1 detoxification by destroying in a non-thermal/microbial way. Structure, and morphology were comprehensively characterized by various spectroscopic analyses.

Non-linear System of Multi-order Fractional Differential Equations: Theoretical Analysis and a Robust Fractional Galerkin Implementation.

This paper presents a comprehensive study of non-linear systems of multi-order fractional differential equations from aspects of theory and numerical approximation. In this regard, we first establish the well-posedness of the underlying problem by investigations concerning the existence, uniqueness, and influence of perturbed data on the behavior of the solutions as well as smoothness of the solutions under some assumptions on the given data. Next, from the numerical perspective, we develop and analyze a well-conditioned and high-order numerical approach based on an operational spectral Galerkin method.

Effects of Photobiomodulation Therapy with Various Laser Wavelengths on Proliferation of Human Periodontal Ligament Mesenchymal Stem Cells.

Several methods have been proposed to enhance the regeneration and healing time in periodontal therapy. Photobiomodulation therapy (PBMT) is a recently suggested novel technique for this purpose. This study aimed to compare the efficacy of PBMT with various laser wavelengths and energy densities on proliferation of human periodontal ligament mesenchymal stem cells (PDLMSCs).

Effects of blended aromatherapy using lavender and damask rose oils on the test anxiety of nursing students.

Background: People experience extreme anxiety in testing situations, so it considers as a psychological condition and can actually impair learning and hurt test performance. People experience some degree of stress and anxiety before and during examinations. This study aimed to investigate the effect of blended aromatherapy using lavender and damask rose oils on the test anxiety of nursing students.
