Development of Fe/SiBr/Si₃N₄/silica fume nanocomposites from recycled metal waste for industrial applications.

Due to the high cost of raw materials, this work aims to benefit from metal waste, especially iron (Fe) and silicon bronze, which results from turning workshops and recycling them to obtain nanocomposites for industrial applications. In this respect, Fe/SiBr/SiN/silica fume nanocomposites possessing superior mechanical, wear, and magnetic characteristics have been produced using powder metallurgy (PM) technology. Milled sample particle size, crystal size, and phase composition were investigated using X-ray diffraction (XRD) technique and transmission electron microscopy (TEM).

Spanlastic Nano-Vesicles: A Novel Approach to Improve the Dissolution, Bioavailability, and Pharmacokinetic Behavior of Famotidine.

: Drugs exhibiting poor aqueous solubility present a challenge to efficient delivery to the site of action. Spanlastics (a nano, surfactant-based drug delivery system) have emerged as a powerful tool to improve solubility, bioavailability, and delivery to the site of action. This study aimed to better understand factors affecting the physicochemical properties of spanlastics, quantify their effects, and use them to enhance the bioavailability of famotidine (FMT), a model histamine H2 receptor antagonist (BCS class IV).

Molecular characterization and risk analysis of Giardia duodenalis assemblages in corticosteroid-treated and non-treated patients in Ismailia, Arab Republic of Egypt.

Background: Giardia duodenalis (G. duodenalis) is an intestinal protozoan parasite of human and animal hosts. The present study investigated and compared the assemblages of G.

The phenotypic spectrum of gene variants.

Introduction: Classically, Usher syndrome is characterized by the association of sensorineural hearing loss (SNHL), retinitis pigmentosa (RP) and possible vestibular dysfunction. Pathogenic bi-allelic variants in cause atypical autosomal recessive Usher syndrome, which is associated with SNHL and photoreceptors dysfunction without vestibular signs. To date, only 19 scattered descriptions have been reported.
