Article Abstract
The influence of different solvents on the extraction medium and the RP-HPLC mobile phase composition were investigated by statistical mixture designs to optimize solvent proportions to prepare the fingerprint of a medicinal herbal extract. For modeling, the number of peaks was used as a measure of fingerprint information. The optimum compositions of solvent to extract chemical substances from green tea and for mobile phase chromatographic analysis were ethyl acetate/ ethanol/dichloromethane (20:5:75 v/v/v) and MeOH/ACN/water (7.5:57.5:35 v/v/v), respectively. This system results in 26 peaks in the chromatographic fingerprint. These results show that an incorrect choice of modifiers for mobile phase composition and solvent extraction hampers the detection of a maximum number of peaks and produces a poor chromatographic fingerprint.

Background: Breast cancer treatment, particularly during the perioperative period, is often accompanied by significant psychological distress, including anxiety and uncertainty. Mobile health (mHealth) interventions have emerged as promising tools to provide timely psychosocial support through convenient, flexible, and personalized platforms. While research has explored the use of mHealth in breast cancer prevention, care management, and survivorship, few studies have examined patients' experiences with mobile interventions during the perioperative phase of breast cancer treatment.

Background: The ability to access and evaluate online health information is essential for young adults to manage their physical and mental well-being. With the growing integration of the internet, mobile technology, and social media, young adults (aged 18-30 years) are increasingly turning to digital platforms for health-related content. Despite this trend, there remains a lack of systematic insights into their specific behaviors, preferences, and needs when seeking health information online.

Background: Mobile health (mHealth) interventions can be effective for people living with HIV, who are sensitive to privacy breach risks. Understanding the perceived experiences of intervention participants can provide comprehensive insights into potential users and predict intervention effectiveness. Thus, it is necessary to plan engagement measurement and consider ways to enhance engagement during the app development phase.

Background: Existing research fails to address the complex nature of nonspecific chronic lower back pain (cLBP ) despite its detrimental effect on economic, societal, and medical expenditures.
Objectives: We developed a nurse-led, mobile-delivered self-management intervention-Problem-Solving Pain to Enhance Living Well (PROPEL-M)-and evaluated its usability, feasibility, and initial efficacy for South Korean adults with nonspecific cLBP.
Methods: This study was composed of two phases: (a) lab and field usability testing for a gamified mobile device application; and (b) a pilot study employing a one-arm pre-test and post-test design among adults aged 18-60 years with nonspecific cLBP.

Nifurtimox (NFX) is a chiral drug used for the treatment of Chagas Disease. Little attention has been paid to the enantioselective properties of chiral drugs used for neglected tropical diseases, highlighting the need for further studies in this area. In this work, the enantioselective properties of NFX were carefully investigated by HPLC using different chiral stationary phases (CSPs) and chromatographic modes.
