Microwave-assisted, sulfhydryl-modified β-cyclodextrin-silymarin inclusion complex: A diverse approach to improve oral drug bioavailability via enhanced mucoadhesion and permeation.

The current study aimed to generate a sulfhydryl-modified β-cyclodextrin-silymarin complex (sulfhydryl-modified β-CD-SMN complex) and to evaluate the enchantment in solubility, permeability, and bioavailability of a model BCS Class IV drug silymarin (SMN). For this purpose, sulfhydryl-modified β-CD was synthesized by replacing all primary and secondary -OH groups at the β-CD backbone with sulfhydryl groups via a novel microwave-assisted technique. Afterward, sulfhydryl-modified β-CD was complexed with silymarin and characterized by FTIR and H NMR spectroscopy.

Efficacy of Lasers in Debonding Ceramic Brackets: Exploring the Rationale and Methods.

The development of ceramic brackets in orthodontics three decades ago emerged as a response to the increasing patient demand for less visible orthodontic appliances. While these brackets provide superior aesthetics, they are characterized by lower fracture toughness and higher bond strength in contrast to metal brackets. These properties present challenges during the debonding step, including the risk of enamel micro-fractures and cracks.

Green Synthesis of Uncoated and Olive Leaf Extract-Coated Silver Nanoparticles: Sunlight Photocatalytic, Antiparasitic, and Antifungal Activities.

The circular economy, which attempts to decrease agricultural waste while also improving sustainable development through the production of sustainable products from waste and by-products, is currently one of the main objectives of environmental research. Taking this view, this study used a green approach to synthesize two forms of silver nanoparticles: coated silver nanoparticles with olive leaf extract (Ag-olive) and uncoated pure silver nanoparticles (Ag-pure), which were produced by the calcination of Ag-olive at 550 °C. The extract and the fabricated nanoparticles were characterized by a variety of physicochemical techniques, including high-performance liquid chromatography (HPLC), thermal gravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM).

Photocatalytic Degradation of Rhodamine-B and Water Densification via Eco-Friendly Synthesized CrO and Ag@CrO Using Garlic Peel Aqueous Extract.

The purification and densification of wastewater play an important role in water recycling, especially if the materials used in water recycling are other types of recycled waste. Therefore, considering this view in this study, the biosynthesis of silver-decorated chromium oxide nanoparticles utilizing a wasted (garlic) peel extract is investigated. The aqueous extract of garlic peel (GPE) was treated with silver nitrate, chromium nitrate, and a mixture of silver nitrate and chromium nitrate to synthesize silver nanoparticles (Ag-garlic), chromium oxide nanoparticles (CrO-garlic), and silver-decorated chromium oxide nanoparticles (Ag@CrO-garlic), respectively.

Phytosynthesis via wasted onion peel extract of samarium oxide/silver core/shell nanoparticles for excellent inhibition of microbes.

The aqueous onion peel extract (OPE) was used to synthesize silver nanoparticles (Ag-onion), samarium oxide nanoparticles (SmO-onion), and silver/samarium oxide core/shell nanoparticles (Ag@SmO-onion). The produced nanoparticles were characterized by thermal gravimetric analysis (TGA), infrared spectra (FT-IR), absorption spectra (UV-Vis), energy band gap, X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), zeta potential, and transmission electron microscopy (TEM). OPE and NPs were tested for the disinfection of some water microbes.

A Pediatric Case of Spinal Intradural Epidermoid Cyst: A Rare Encounter.

Intradural epidermoid cysts of the spine are rare congenital lesions. Their etiology is thought to stem from ectodermal remnants during embryonic development. They result in a diverse clinical presentation, often marked by an insidious onset and variable neurological deficits.

Preparation, Characterization of Pregabalin and Extract-Loaded Topical Gel and Their Comparative Effect on Burn Injury.

The current study depicts the comparative effects of nanogel using extract, pregabalin alone, and a co-combination gel. The gels prepared were then analyzed for conductivity, viscosity, spread ability, globule size, zeta potential, polydispersity index, and TEM. The globule size of the co-combination gel, determined by zeta sizer, was found to be (329 ± 0.

Extraction Optimization of Mucilage from Seeds of by Response Surface Methodology.

seed mucilage (MPM) is composed of glucuronoxylan, which is a swellable, pH-responsive and non-toxic biomaterial. Herein, we aimed to extract MPM from seeds (MP seeds) to ascertain optimization of extraction conditions to get highest yield by response surface methodology, via Box-Behnken design (RSM-BBD). MPM was extracted from MP seeds by a hot water extraction method.
