Carbon nitride grafted with single-atom manganese and 2-hydroxy-4,6-dimethylpyrimidine: A visible-light-driven photocatalyst for enhanced ozonation of organic pollutants.

The development of durable and highly efficient visible-light-driven photocatalysts is essential for the photocatalytic ozonation process towards degrading organic pollutants. This study presents CN-MA, a novel photocatalyst synthesized by grafting carbon nitride (CN) with single-atom Mn and 2-hydroxy-4,6-dimethylpyrimidine (HDMP) via one-step thermal polymerization. Experimental characterization and theoretical calculation results reveal that incorporating single-atom Mn and HDMP into CN alters the charge density distribution on the heptazine rings.

Umbrella review of risk factors for inflammatory bowel disease: a study protocol.

Introduction: Inflammatory bowel disease (IBD) is a chronic idiopathic inflammatory disorder that arises from complex interactions between genetics, environment and gut microbiota. It encompasses Crohn's disease, ulcerative colitis and IBD-unclassified. The protracted course of IBD imposes a significant burden on patients' quality of life, economic productivity, social functioning, as well as treatment, hospitalisation and surgery.

Development and Pilot Usefulness Testing of an Interactive Computerized Patient Decision Aid for Intraocular Lens Selection Before Cataract Surgery.

Purpose: Modern cataract surgeries aim to treat impaired vision and also improve quality of life. An appropriate pre-operative selection of the intraocular lens is important to post-operative quality of life. Patients often have difficulty in choosing the best fit for individual needs.
