The recognition of specific genomic arrangements by rationally designed small molecules is fundamental for the expansion of targeted gene expression. Here, we report the first X-ray crystal structures that demonstrate single G (guanine) recognition by a highly selective diamidine (DB2447) in a mixed DNA sequence. The study presents detailed structural information on the mechanism of single G recognition by D2447 and its various interactions in the DNA minor groove. Molecular dynamics and binding studies were used to evaluate the details of our reported structures. The study provides structural insight and resources necessary for understanding single G selection in genomic sequences.

Objective: Unidentified sex differences in old-age cognition may emerge in psychometric networks, which look beyond mean scores into the unique cognitive structure of males and females. Accordingly, this study aims to examine cognition in well-functioning older males and females with psychometric network analysis.
Methods: The current cohort (N = 2,802) of community-dwelling adults (≥65 years) was derived from the Advanced Cognitive Training for Independent and Vital Elderly study.

Background: The effect of conservative treatments on sleep quality in carpal tunnel syndrome is unclear.
Purpose: Comparing the effect of splinting and kinesiotaping in carpal tunnel syndrome on functional status, pain, grip strength, nerve cross-sectional area and sleep quality.
Study Design: Randomized controlled study.

Background/purpose: The competency-based Internal Medicine Milestones (IMM) assesses physician training outcomes through six key competencies. This pilot study introduced IMM concepts through an echocardiography report interpretation course for postgraduate students (PGYs) and residents (Rs). We aimed to help young physicians understand and track competency development as they receive cardiovascular training, with a view to expanding IMM usage for all junior physicians.

Background: Ethanol ablation (EA) has been proposed as a first-line treatment modality for recurrent symptomatic cystic thyroid nodules following initial aspiration. The efficacy of EA can be compromised when the initial nodule volume exceeds 10 mL. This study assessed the efficacy of single-session EA in managing thyroid cysts with an initial volume of ≥10 mL.
