In this study, a straightforward spectrophotometric method was developed for quantifying the total content of chalcones in a sample. The method exhibits linearity, accuracy, precision, repeatability, and enables the estimation of total chalcone content in trans-chalcone equivalents for a sample diluted in carbon tetrachloride and added to antimony pentachloride. The analytical wavelength was determined to be 390 nm.

We used linked national dispensing and pathology data to identify people aged 14+ years initiating PrEP in 2018. We estimated non-adherence using the proportion of days covered (PDC), defining non-adherence as PDC < 60%.

- The study aims to provide updated evidence for managing stage I colon cancer (CC) post-surgery, focusing on recurrence rates and risk factors.
- Despite low recurrence risk, some guidelines suggest intensive follow-up is unnecessary, but data on actual recurrence rates is limited.
- The findings reveal a 5% recurrence rate, primarily systemic, with significant risk factors including tumor characteristics and patient demographics, suggesting a need for improved postoperative follow-up strategies.
Purpose: Acute appendicitis during pregnancy poses unique challenges due to altered anatomical and physiological dynamics and concern about foetal well-being. This study aimed to assess management strategies and outcomes of acute appendicitis during pregnancy, focusing on non-operative management versus surgical intervention.
Methods: The study is based on the computerized healthcare utilization database of Lombardy.
Solid-state batteries offer significant advantages but present several challenges. Given the complexity of these systems, it is good practice to begin the study with simpler models and progressively advance to more complex configurations, all while maintaining an understanding of the physical principles governing solid-state battery operation. The results presented in this work pertain to cells without traditional electrodes, thus providing a foundation for guiding the development of fully functional solid-state cells.
