Pharmacists' perceptions of the impact of Objective Structured Clinical Examination on professional development and competence: a cross-sectional study in Qatar.

Objectives: The Objective Structured Clinical Examination (OSCE) is a key tool in healthcare education, assessing clinical skills and competencies. This study explores OSCE's impact on pharmacists' competence, confidence, and practice readiness, focusing on its role in professional development and long-term practice improvement.

Methods: A cross-sectional survey was conducted among Qatar University pharmacy graduates with at least a year of practice experience.

Wharton's Jelly Mesenchymal Stem Cells: Shaping the Future of Osteoarthritis Therapy with Advancements in Chitosan-Hyaluronic Acid Scaffolds.

This review explores the potential of Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs) in cartilage regeneration and osteoarthritis treatment. It covers key factors influencing chondrogenesis, including growth factors, cytokines, and hypoxia, focusing on precise timing. The effectiveness of three-dimensional cultures and scaffold-based strategies in chondrogenic differentiation is discussed.

Independent concentration extraction as a novel green approach resolving overlapped UV-Vis binary spectra and HPTLC-densitometric methods for concurrent determination of levocloperastine and chlorpheniramine.

Background: The proposed research study introduces independent concentration extraction (ICE) as a novel UV-Vis spectrophotometric approach. The approach can be used for extracting the concentration of two analytes with severely overlapped spectra from their binary mixtures. ICE is based on spectral extraction platform involving simple smart successive methods that can directly extract the original zero order spectra of the analytes at their characteristic (λ).

Organ-On-A-Chip Devices: Technology Progress and Challenges.

Organ-On-a-Chip (OOC) is a multichannel 3D-microfluidic cell-culture system incorporated in a chip that simulates the behavior of an organ. This technology relies on a multidisciplinary science that benefits from and contributes in the progress of many fields including microbiology, microfluidics, biomaterials, and bioengineering. This review article summarizes the progress and achievements of various organ-on-chip technologies.
