Application


  • Phosphoryl Trichloride-Method of Determination in Workplace Air.: This study focuses on the analytical determination of phosphoryl trichloride in workplace air using hydrochloric acid as a reagent. The method was validated and applied to assess the exposure of workers to this hazardous compound in industrial settings (Kowalska et al., 2023).

  • Interference of Preservatives on Urinary Iodine Measurement by Sandell-Kolthoff Method.: This research examines the impact of preservatives, including hydrochloric acid, on the accuracy of urinary iodine measurements. The study highlights the need for careful selection of preservatives to avoid analytical interference (Kaya et al., 2022).

  • Monitoring the Extraction of Copper from Chicken Dung Leachate Using an Aluminium Electrode as an Indicator.: The study explores the use of hydrochloric acid in the leaching process of copper from chicken dung. It demonstrates the effectiveness of hydrochloric acid in extracting metals from organic waste materials (Kugeria et al., 2019).

  • Determination of Single-Ion Activities of H+ and Cl- in Aqueous Hydrochloric Acid Solutions by Use of an Ionic Liquid Salt Bridge.: The research provides a novel approach to determining the activities of hydrogen and chloride ions in hydrochloric acid solutions using an ionic liquid salt bridge, contributing to the understanding of ion behavior in aqueous solutions (Sakaida et al., 2011).

Maturation of functional neuronal circuits during central nervous system development relies on sophisticated mechanisms. First, axonal and dendritic growth should reach appropriate targets for correct synapse elaboration. Second, pruning and neuronal death are required to eliminate redundant or inappropriate neuronal

CYP2D metabolically activates codeine to morphine, which is required for codeine analgesia. Permeability across the blood-brain barrier, and active efflux, suggests that initial morphine in the brain after codeine is due to brain CYP2D metabolism. Human CYP2D is higher in

Metformin is the mainstay therapy for type 2 diabetes (T2D) and many patients also take salicylate-based drugs [i.e., aspirin (ASA)] for cardioprotection. Metformin and salicylate both increase AMP-activated protein kinase (AMPK) activity but by distinct mechanisms, with metformin altering cellular
