Cleft Palate Surgery: Evolving Surgical Techniques and Reconstructive Principles for Oronasal Fistula and Velopharyngeal Dysfunction: A Narrative Review

Background Despite more than a century of surgical innovation, no single palatoplasty technique has demonstrated consistently superior outcomes across the spectrum of cleft palate phenotypes. Objective This review examines the historical evolution of cleft palate reconstruction a...

Green synthesis for production of chromium(III) oxide nanoparticles in fine powder

In this paper, a green synthesis method for chromium(III) oxide nanoparticles (Cr 2 O 3 NPs) is presented. The proposed route utilizes weed biomass as a reducing agent to produce a solid solution that readily precipitates as a fine powder of Cr₂O₃ nanoparticles. The synthesized C...
