Illegal additives such as oxyphenisatine and its esters are prevalent in the slimming food industry, necessitating a robust analytical method for their detection. This study presents a novel UPLC-MS/MS method for the rapid and accurate quantification of total oxyphenisatine levels in fermented green plum, following hydrolysis of its esters. An efficient ultrasonic extraction with a methanol and 0.

Purpose: The purpose of this study was to characterize whether pulsed ultrasound (PUS) affects transscleral drug delivery.
Methods: Fluorescein sodium (NaF, 376 Da) and fluorescein isothiocyanate-conjugated dextran 40 (FD-40, 40 kDa) were used as model drugs. Human sclera grafts were placed in modified Franz diffusion cells and were treated by PUS (1 megahertz [MHz], 0.

Acute Kidney Injury (AKI) is a significant medical condition characterized by the abrupt decline in kidney function.Low-intensity pulsed ultrasound (LIPUS), a non-invasive therapeutic technique employing low-intensity acoustic wave pulses, has shown promise in promoting tissue repair and regeneration. A novel LIPUS system was developed and evaluated in rat AKI models, focusing on its effects on glomerular filtration rate (GFR), blood urea nitrogen (BUN), serum creatinine (SCr), and the Notch1-Akt-eNOS signaling pathway.

Craniosynostosis is rarely diagnosed in utero. Prenatal diagnosis has the potential to improve patient outcomes and streamline care, however, and is becoming more feasible as technology improves. The objective of this study is to examine existing literature on prenatal diagnosis of nonsyndromic craniosynostosis.

Background: Treatment of deep carious lesions poses significant challenges in dentistry, as complete lesion removal risks compromising pulp vitality, while selective removal often reduces the longevity of restorations. Herein, we propose a minimally invasive approach using High-Intensity Focused Ultrasound (HIFU) for microscale removal of carious dentine. Concurrently, HIFU's antimicrobial effects against associated cariogenic biofilms and the corresponding thermal and biological impacts on surrounding tissues were investigated.
