Iridium Nanocrystals Enriched with Defects and Atomic Steps to Enhance Oxygen Evolution Reaction Performance.

The presence of defects can significantly improve catalytic activity and stability, as they influence the binding of the reactants, intermediates, and products to the catalyst. Controlling defects in the structures of nanocrystal catalysts is synthetically challenging. In this study, we demonstrate the ability to control the growth of Ir nanocrystals, enabling the tuning of both structural and surface defects.

Performance assessment of artificial intelligence chatbots (ChatGPT-4 and Copilot) for sharing insights on 3D-printed orthodontic appliances: A cross-sectional study.

Objective: To evaluate and compare the performance of OpenAI's ChatGPT-4 and Microsoft Copilot in providing information on 3D-printed orthodontic appliances, with a focus on the accuracy, completeness of the content, and response generation time.

Methods: This cross-sectional study proceeded in five stages. Initially, three orthodontists created a total of 125 questions concerning 3D printed orthodontic appliances of which 105 questions were finalized to be incorporated into the study by a panel of senior orthodontists.

Assessment of attitude towards e-professionalism: Students' perspectives from a Private Medical College in Lahore, Pakistan.

Objective: This study was conducted to investigate the social media practices and attitudes towards e-professionalism among undergraduate medical students in a medical college of Pakistan.

Methods: This cross-sectional study was conducted on 220 undergraduate medical students from 2 to final-year MBBS, at CMH Lahore Medical College from March to August 2022.

Effect of Gender on Metabolic and Neurodevelopmental Parameters of Postnatally Growth-Restricted Rats Undergoing Catch-Up Growth.

Objective: To determine the long-term effects of early postnatal malnutrition and various degrees of catch-up growth on metabolic (serum glucose, leptin, triacylglycerides) and neurodevelopmental parameters (learning and memory) among male and female rodent models, mimicking human preterm infants.

Study Design: Randomized controlled trial. Place and Duration of the Study: CMH Multan Insitute of Medical Sciences, from September 2021 to December 2021.

From an incidental lipoma to ileo-ileal intussusception in an adult: A case report.

Introduction And Importance: Intussusception in adults is rare, constituting a miniscule number of bowel obstruction pathologies. Clinical practice often considers it a last-resort diagnosis, as other causes of mechanical small bowel obstruction are more common. The diagnosis is a challenging one to make, as the "telescoping" motion of the intestines fluctuates in a waxing-and-waning nature.
