The combined study of stable isotopes and ancient proteins is a very promising approach to reconstructing past human diets. This study uses stable isotope carbon (C), nitrogen (N), and sulfur (S) signatures from dental calculus, dentin, and bone of individuals from a monastic cemetery at Dalheim (North Rhine-Westphalia, Germany) dating to the ninth-twelfth centuries CE. In addition, we examined ancient proteins from the dental calculus of these individuals, complemented by the analysis of a second medieval site in Baar-Früebergstrasse (Zug, Switzerland) dating to the seventh century CE.

The objective was to study the organizational impact of the UC performed before bladder instillations, defined as the number and proportion of BCG instillations postponed due to a positive urine culture result.
Methods: Induction BCG records in a single academic center between 2015 and 2020 were retrospectively reviewed.
We present a novel light-locked dynamic covalent polymerization methodology to synthesize conjugated polymers based on BisAzaCoroneneDiimides (BACDs). This metal-free process converts reversible poly imines into kinetically locked conjugated polymers using visible light, generating minimal side products. By incorporating aldehyde-functionalized comonomers, the approach enables the creation of diverse n-type semiconducting polymers with tunable optical band gaps and low LUMO levels.

Methods: French certified and in-training urologists were invited to participate in an online survey between April and May 2024, including 18 questions assessing demographics, practice trends, awareness of the new guidelines, their dissemination and impact on daily practice.
Introduction: Outpatient transurethral resection of bladder tumors (TURBT) is not widespread, involving only 5% of patients. Our aim was to assess the feasibility of TURBT in an outpatient setting and to evaluate factors possibly associated with conversion to inpatient care.
Methods: All consecutive outpatient-TURBT performed between January 2016 and December 2022 in one academic center was retrospectively analyzed.
