A comparison of the effectiveness of standard anterior bracket placement versus smile arc protection method: A randomized clinical trial.
J World Fed Orthod
March 2025
Dental Research Center, Orthodontics Department, Mashhad University of Medical Sciences, Mashhad, Iran. Electronic address:
Objectives: This randomized two-arm parallel trial aimed to compare the effectiveness of standard anterior bracket positioning with the smile arc protection (SAP) method in terms of occlusal and smile morphometric indices, and perceived post-treatment smile aesthetics.
Methods: Patients needing nonextraction orthodontic treatment were randomly assigned to either the SAP or standard bracket placement group. Inclusion criteria were ages 11 to 25 years, nonextraction treatment, and good oral hygiene, all treated using the Roth 0.
Omega-3 index improves upon the pooled cohort equation in predicting risk for CVD.
J Clin Lipidol
February 2025
Fatty Acid Research Institute, Sioux Falls, SD, USA (Drs Tintle, Marchioli, and Harris); Department of Internal Medicine, Sanford School of Medicine, University of South Dakota, Sioux Falls, SD, USA (Dr Harris).
Background: Accurate predictive tools are crucial for identifying patients at increased risk for atherosclerotic cardiovascular disease (ASCVD). The Pooled Cohort Equation (PCE) is commonly used to predict 10-year risk for ASCVD, but its accuracy remains imperfect.
Objective: This study examined the extent to which the omega-3 index (O3I; the proportion of eicosapentaenoic acid+docosahexaenoic acid in erythrocyte membranes) improved the predictive capability of PCE.
Deep-Learning-Assisted Understanding of the Self-Assembly of Miktoarm Star Block Copolymers.
ACS Nano
March 2025
School of Chemical Science and Engineering, Tongji University, 1239 Siping Road, Shanghai 200092, China.
The self-assemblies of topological complex block copolymers, especially the AB type miktoarm star ones, are fascinating topics in the soft matter field, which represent typical self-assembly behaviors analogous to those of biological membranes. However, their diverse topological asymmetries and versatile spontaneous curvatures result in rather complex phase separations that deviate significantly from the common mechanisms. Thus, numerous trial-and-error experiments with tremendous parameter space and intricate relationships are needed to study their assemblies.

The Health Research Unit Zimbabwe, Biomedical Research and Training Institute, Harare, Zimbabwe.
Low vitamin D associated with high parathyroid hormone (PTH) is commonly reported in the context of HIV infection. We determined the association between total 25-hydroxyvitamin-D [25(OH)D] and PTH in adolescents living with HIV, in Zambia and Zimbabwe. Adolescents (11-19 years) perinatally-infected with HIV and established on antiretroviral therapy (ART) for ≥6 months were recruited into a cross-sectional study.
