Description

• Application: Validation and application of an online extraction and liquid chromatography tandem mass spectrometry assay for the analysis of delamanid and its DM-6705 metabolite in human breast milk.: This study presents a validated method for analyzing delamanid and its metabolite in human breast milk, using ammonium carbonate in the sample processing phase. The technique offers a robust tool for therapeutic drug monitoring in breastfeeding mothers (Mkhize et al., 2024).Visualizing the Internal Nanocrystallinity of Calcite Due to Nonclassical Crystallization by 3D Coherent X-Ray Diffraction Imaging.: Research utilizing ammonium carbonate to influence the crystallization process of calcite, providing insights into the nonclassical pathways of nanocrystal formation and transformation in a controlled environment (Suzana et al., 2024).Ammonia measurement in human breath of subjects with Helicobacter pylori using photoacoustic spectroscopy.: This study details a method for detecting ammonia in the breath of patients infected with Helicobacter pylori, using ammonium carbonate as a calibration standard, which could lead to non-invasive diagnostic approaches (Popa et al., 2024).Determining Ultrasound Parameters for Bursting Polymer Microbubbles for Future Use in Spinal Cord Injury.: Discusses the development of ultrasound parameters for bursting polymer microbubbles encapsulating agents like ammonium carbonate, aimed at targeted therapies for spinal cord injuries (Oeffinger et al., 2024).
