An Upgraded Solid-Phase Assembly of Chelators (DOTA and NOTA) Enabled Bacterial Uptake Studies of Radiolabeled Peptide.

Among popular radio metal chelators, DOTA and NOTA have been remarkably considered in radionuclide therapy and imaging studies due to several advantages in pharmacology. Here, we developed a practical and general method for assembling DOTA and NOTA in the solid phase peptide (pseudo-dilute conditions) using a wide range of solvents with easily accessible and economical feedstocks, which mitigated unprecedented challenges associated with previously reported methods. This upgraded approach enabled an efficient installation of these two chelators on various bioactive peptide sequences.

"I was in a very deep, dark place... I wasn't prepared for that": A qualitative assessment of the emotional well-being needs of patients undergoing cystectomy.

Introduction: Studies have shown that cystectomy has a large psychological burden on patients with bladder cancer. However, there has been little work characterizing areas of improvement. This project aimed to understand cystectomy patients' experiences and to identify patient-centered methods to improve perioperative support.

Agar dilution test and its Merits and Drawbacks in evolving dynamics of colistin susceptibility.

Objectives: Automated results for determining colistin susceptibility tests are unreliable, micro broth dilution requires expertise, and CBDE has limited dilutions. International Consensus Document of 2022 suggested that agar dilution was unacceptable due to varying results in the literature.

Methods: The study was designed to evaluate the agar dilution method for colistin susceptibility in CRE isolates compared to CBDE.

"…I Wish Someone Told Me About That…": A Qualitative Assessment of the Educational Needs of Patients Undergoing Cystectomy.

Objective: To utilize patient feedback to identify areas of need for information and ways to improve delivery of education, due to recognition that cystectomy and urinary diversion is a complex operation often overwhelming patients and caregivers.

Methods: We conducted 5 focus groups of bladder cancer patients (separated by gender and diversion type) treated with cystectomy and urinary diversion (n = 17). Questions focused on areas of improvement for patient education.

Harnessing a bis-electrophilic boronic acid lynchpin for azaborolo thiazolidine (ABT) grafting in cyclic peptides.

Chemical modifications of native peptides have significantly advanced modern drug discovery in recent decades. On this front, the installation of multitasking molecular grafts onto macrocyclic peptides offers numerous opportunities in biomedical applications. Here, we showcase a new class of borono-cyclic peptides featuring an azaborolo thiazolidine (ABT) graft, which can be readily assembled utilizing a bis-electrophilic boronic acid lynchpin while harnessing the inherent reactivity difference (>10 M s) between the N-terminal cysteine and backbone cysteine for rapid and highly regioselective macrocyclization (∼1 h) under physiological conditions.
