Article Synopsis
- Ultrasound tomography needs low-frequency data to ensure accurate imaging and prevent errors in full-waveform inversion (FWI)
- The method can generate low-frequency data from high-frequency signals using frequency-difference beamforming
- Simulations and experiments show significant improvements in image quality and clarity of internal structures due to this technique.
Purpose: This study aimed to determine the perceptions of senior medical students and recent graduates from College of Medicine (CMED) at Qatar University regarding their undergraduate education and training related to prescribing, their confidence in achieving the learning outcomes specified in the curriculum and their preparedness to prescribe in practice.
Patients And Methods: This was a cross-sectional web-based survey with qualitative elements, utilizing a 22-item pre-validated questionnaire developed through a multi-phase iterative process. The survey was administered to all senior medical students (year 4-6) and recent graduates of CMED at Qatar University.
Article Synopsis
- The study investigates the anti-cancer and anti-bacterial properties of medicinal plant extracts, focusing on two specific herbs, through various extraction methods.
- The extracted compounds were tested against methicillin-resistant bacteria and various cancer cell lines, showing significant antibacterial activity and effective dose-dependent anti-cancer effects.
- Findings revealed the presence of active metabolites that may serve as potential therapeutic agents, paving the way for future research into their applications in treating infections and cancer.
: We developed delafloxacin (Dela)-loaded PLGA nanoparticles (PNPs) for potential ocular application a topical route to treat eye infections caused by Gram-positive and Gram-negative bacteria. : Dela-PNPs were formulated using the emulsification-solvent evaporation method and stabilized using poly(vinyl alcohol) (PVA). Size and morphology were characterized by using dynamic light scattering (DLS) and scanning electron microscopy (SEM).

Knowledge of the pathology of uncommon renal neoplasms along with radiological and clinical correlations often aids in correct diagnosis.
Aims: The present study aims to describe the cytomorphological and immunohistochemical findings in the varied spectrum of renal tumors, other than renal cell carcinomas (RCC).
