Preparation, antioxidant, antibacterial, and in vivo evaluation of pomegranate flower extract nanofibers based on thiolated chitosan and thiolated gelatin for treating aphthous stomatitis.

Recurrent aphthous stomatitis (RAS) is a common condition that manifests as ulcerative lesions in the oral mucosa. In this study, bilayer, mucoadhesive nanofibers loaded with pomegranate flower extract (PFE) were prepared using thiolated gelatin (TGel) and thiolated chitosan (TCS) as the active layer and drug-free polycaprolactone (PCL) as the backing layer. Gelatin (Gel) and chitosan (CS) were successfully thiolated (proven by Ellman's assay, solubility, H NMR, FTIR, Raman spectroscopy, and XRD) and electrospun into active nanofibrous layers with a diameter of 356.

Impact of saline irrigation on the early mechanical characteristics and microstructure of bone cement.

Very high heat is generated during the polymerization of poly (methyl methacrylate) (PMMA) bone cement, which is used for implant fixation in orthopedic surgery. As such, it has been suggested that irrigating the bone cement layer in the surgical site with a saline solution is a way of cooling the layer. In this study, we aimed to determine the influence of irrigation with a saline solution on the flexural strength and the microstructure of the test specimens of two PMMA bone cement brands: Simplex P and FIX 1.

Analysis of essential oil composition and assessing the antibacterial and antioxidant properties of the ethanol extract.

The increasing issue of antibiotic resistance in bacterial infections has led to challenging and costly treatments. Free radicals significantly contribute to the progression of several diseases, such as cardiometabolic disorders, neurodegenerative conditions, and cancers. Antioxidants can help alleviate or prevent these health problems.

Thermosensitive multivesicular liposomal hydrogel: a potential platform for loco-regional drug delivery in the treatment of osteomyelitis caused by antibiotic-resistant biofilm-forming bacteria.

Biofilm-mediated osteomyelitis presents significant therapeutic challenges. Given the limitations of existing osteomyelitis treatment approaches, there is a distinct need to develop a localized drug delivery system that is biocompatible, biodegradable, and capable of controlled antibiotic release. Multivesicular liposomes (MVLs), characterized by their non-concentric vesicular structure, distinct composition, and enhanced stability, serve as the system for a robust sustained-release drug delivery platform.

Comparison of the Efficacy of Povidone-Iodine with Mupirocin in Decolo-nizing Staphylococcus aureus from the Nasal Cavity of Healthcare Work-ers: A Single-Blinded Randomized Controlled Trial.

Background: Nasal colonization of Staphylococcus aureus increases the risk of nosocom-ial infections. Therefore, medications that can decolonize this pathogen can help prevent such infec-tions.

Objective: Our study aimed to compare the efficacy of povidone-iodine solution with intranasal mupi-rocin ointment in decolonizing S.
