This study explores the impact of short-term annealing on the thermal stability and mechanical properties of oxygen-free copper subjected to high-pressure torsion (HPT). Copper samples were deformed through HPT with varying numbers of turns at room temperature and subsequently subjected to short-term annealing at temperatures of 398 K and 423 K. Microstructural analysis revealed that annealing led to grain growth and a reduction in dislocation density, with samples processed with fewer HPT turns exhibiting more significant grain coarsening.

Mg-8Al-1Zn magnesium alloy was successfully processed using deferential speed rolling (DSR) at temperatures of 400 and 450 °C for thickness reduction of 30, 50, and 70% with no significant grain growth and dynamic recrystallization. Using optical microscopy (OM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM), the rolled microstructures were examined. Although the results indicate a slight reduction in grain size from the initial condition, the DSR processing of alloy at an elevated temperature was associated with a significant number of twins and a distribution of the fine particles of the second phase.

Objectives: Creating environmentally sustainable healthcare culture within the dental field requires embedding the content in the dental curriculum at the undergraduate level. This study aimed to explore the current awareness and drivers among dental students and educators regarding environmentally sustainable dentistry (ESD) in the United Arab Emirates (UAE) and identify barriers and enablers to embrace it.

Methods: A cross-sectional survey using online questionnaires was carried out in six undergraduate dental education institutes within the UAE.

Objective: This is a comprehensive characteristic study of Kawasaki disease (KD) and Multi system inflammatory syndrome in children (MIS-C) in the Middle East that creates a formula to differentiate between the two.

Methods: We conducted a descriptive comparative study of KD and MIS-C in the United Arab Emirates. Retrospective MIS-C and KD cohorts were recruited between January 2017 until August 2021.

Article Synopsis
  • Significant healthcare challenges are posed by rare diseases in underserved areas like the Middle East, which lack genomic diagnostic services.
  • A clinical genomics facility was established in the UAE to diagnose and manage rare disease patients, utilizing methods like exome sequencing and chromosomal microarrays, demonstrating a cumulative diagnostic yield of 32.5%.
  • The majority of diagnosed Mendelian disorders were identified in young patients, with many receiving delayed diagnoses due to limited access to genetic testing, highlighting the importance of local genomic services for timely management.
