Magnesium is an essential mineral in biological systems and has a significant impact on brain health. Its deficiency has been found to correlate with irregular metabolic processes and neurodevelopmental disorders. The objective of this research was to establish and validate an analytical approach based on the standard addition methodology for determining endogenous magnesium levels in the serum of autistic and healthy children.

Emissions of metals and metalloids as a result of industrial processes, entail a great risk to human health. A high time resolution study on arsenic levels in PM in the city of Huelva (SW Spain) was carried out between September 2021 and September 2022. Hourly data obtained with a near real-time technique based on X-ray fluorescence were inter-compared with other offline analytical instrumentation.

Meeting the contemporary demand for the development of functional, biocompatible, and environment friendly self-assembled structures using efficient, cost-effective, and energy-saving methods, the field of colloids has witnessed a surge in interest. Research into cationic and anionic (catanionic) surfactant combinations has gained momentum due to their distinct advantages and synergistic properties in this context. Catanionic self-assemblies have emerged as promising contenders for addressing these requirements.

The FDA "Food and Drug Administration" recently approved a novel co-crystal formulation of Celecoxib (CEX) and Tramadol (TRM) for the treatment of adults suffering from moderate to severe pain in several conditions. This novel combination has advantages over co-administration of the two drugs individually as better patient compliance, synergism and lower therapeutic cost. This work presents the first "High performance Thin Layer Chromatographic" (HPTLC) quantitative analytical technique for CEX and TRM simultaneous assay in bulk, their new dosage form and plasma.
