The one-pot transamination reactions on a zwitterionic benzoquinonemonoimine yield either a quinoxaline derivative or bis-zwitterionic macrocycles, depending on the number of carbon atoms bridging primary polyamines. These latter products, featuring two confined donor cavities, are the result of a [2 + 2] condensation without the need for template effect or high dilution conditions.

Understanding SSIs' incidence and risk factors is crucial for improving patient outcomes. This study aimed to identify the various risk factors contributing to SSIs in a tertiary hospital, with the goal of informing better clinical practices and preventive measures.

This study aims at comparing the postoperative outcomes and complication rates of monopolar transurethral resection of the prostate (TURP) in BPH patients with and without AUR. By examining the differences in postoperative outcomes, the study seeks to highlight the impact of AUR on complications such as UTIs, prolonged catheterization, and extended hospital stays, and assess the potential clinical implications for improving treatment strategies in these patients.

Their heuristic and groundbreaking work proposed that combining multiple polymethine subunits within a single chromophore enables orbital coupling, consequently narrowing the HOMO-LUMO gap, and yielding redshifted optical properties. These outcomes are particularly valuable for developing organic dyes tailored for visible-to-near-infrared applications.

Identifying the clinical and biochemical risk factors associated with these abnormalities can aid in early intervention and prevention strategies. This study aimed to assess the association between lipid profiles, age, gender, smoking habits, hypertension, and carotid wall abnormalities in patients.
