Arresting Active Carious Lesions Using Minimal Intervention Dentistry among a Group of Preschool Children: A Randomized Controlled Clinical Trial.

Objectives: This clinical trial investigated the effectiveness of three minimal intervention dentistry protocols in arresting dentin caries in primary molars of preschool children. Treatment time, anxiety in children, adverse events, and parents' esthetic perception were all assessed.

Materials And Methods: One hundred thirty-five 3-5-year-old children with active dentin caries lesions on the occlusal surface of primary molars were randomly allocated to the control group receiving atraumatic restorative treatment (ART) and two test groups receiving 38% silver diamine fluoride (SDF) or ultraconservative treatment (UCT).

Molecular Imprinting as a Tool for Exceptionally Selective Gas Separation in Nanoporous Polymers.

The alarming rise in atmospheric CO levels, primarily driven by fossil fuel combustion and industrial processes, has become a major contributor to global climate change. Effective CO capture technologies are urgently needed, particularly for the selective removal of CO from industrial gas streams, such as flue gas and biogas, which often contain impurities like N and CH. In this study, we report the design and synthesis of novel molecularly imprinted polymers (MIPs) using 4-vinylpyridine (4VP) and methacrylic acid (MAA) as functional monomers, and thiophene (Th) and formaldehyde (HC) as molecular templates.

Establishing the Saudi pediatric and youth diabetes registry: initial data and challenges.

The Saudi National Diabetes Registry focuses mainly on adult patients. In 2020, the National Guard Health Authority (NGHA) launched the Saudi Pediatric and Youth Diabetes Registry (SPYDR), for children and adolescents with diabetes. This report is about the first data and the challenges we faced during SPYDR initiation.

Comparative analysis of lipid-peptide nanoparticles prepared via microfluidics, reverse phase evaporation, and ouzo techniques for efficient plasmid DNA delivery.

In the current "era of lipid carriers," numerous strategies have been developed to manufacture lipid nanoparticles (LNPs). Nevertheless, the potential impact of various preparation methods on the characteristics, use, and/or stability of these LNPs remains unclear. In this work, we attempted to compare the effects of three different preparation methods: microfluidics (MF), reverse phase evaporation (RV), and ouzo (OZ) on lipid-peptide NPs (LPNPs) as plasmid DNA delivery carriers.
