Objective: Endometriosis ultrasound is an accurate, cost-effective, and non-invasive diagnostic tool that can help improve the diagnostic delay that patients with endometriosis experience. As an emerging diagnostic method, the perspectives of patients undergoing endometriosis ultrasound remain unexplored. Therefore, the objective of this study was to develop and validate an assessment tool that evaluates patient-reported experiences with endometriosis ultrasound as a decision-making tool.

Article Synopsis
  • The study developed a new adsorbent (AlNi-LDH/CS) by combining layered double hydroxide with chitosan for more effective removal of bivalent Pb(II) from solutions.
  • The material was thoroughly analyzed using various techniques to evaluate its properties, showing a specific surface area of 71.95 m²/g and an average pore size of 2.537 nm, which is crucial for its adsorption capabilities.
  • The research identified optimal conditions for adsorption, finding that at pH 5 with a specific dosage, the adsorbent can remove up to 453.05 mg/g of Pb(II), while also demonstrating strong stability and reusability across multiple cycles.

A ternary mixture incorporating Hydroxyzine hydrochloride (HYX), Ephedrine hydrochloride (EPH) and Theophylline (THP) frequently prescribed for the treatment of respiratory diseases. Herein, two spectrophotometric methods are designated and applied to resolve these three components in their mixture. Method A is ratio-subtraction combined with derivative spectrophotometry, where THP can be determined directly at its λmax 271 nm (neither HYX or EPH interfere), then for determination of HYX and EPH, the ternary mixture was divided by 22 μg/mL of THP and after subtraction of the plateau region, HYX can be determined directly at its λmax 234.

A cost-effective, selective, sensitive, and operational TLC-densitometric approach has been adapted for the concurrent assay of Hydroxyzine Hydrochloride (HYX), Ephedrine Hydrochloride (EPH), and Theophylline (THP) in their pure powder and pharmaceutical forms. In the innovative TLC-densitometric approach, HYX, EPH, and THP were efficaciously separated and quantified on a 60F silica gel stationary phase with chloroform-ammonium acetate buffer (9.5:0.
