Covalent Attachment of a Platinum(II) Complex inside DNA Duplexes

ChemistryEurope, EarlyView.
Oxidative addition is used for the site‐specific incorporation of an organometallic PtII complex as an artificial nucleobase into a DNA duplex. The platination stabilizes the duplex and confers it with phosphorescence. An organometallic phosphorescent PtII complex is introduced into DNA duplexes via oxidative addition to a tailor‐made artificial ...

Caffeine Content Assessment in Beverages and Food Supplements: Regulatory Challenges and Health Implications

ChemFoodChem, EarlyView.
ABSTRACT This study presents an analysis of caffeine content in food supplements and evaluates current regulatory frameworks against established safety guidelines. High‐caffeine products, particularly sports, and food supplements, were assessed for compliance with the safety opinion of the European Food Safety Authority (EFSA). The investigation during

Evolved DNAzymes and Stable Activation Chemistry Enable High‐Efficiency DNA Ligation

Chemistry – A European Journal, EarlyView.
In vitro selection of pre‐structured DNA libraries and chemical screening of alternative activation groups yielded trans‐acting DNAzymes with faster ligation rates and enhanced DNA substrate stability. The combination of C3S1 DNAzymes and phosphobenzimidazole‐activated DNA substrates provides improved DNA ligation performance, offering promise for ...

Metabolic changes during cardiac regeneration in the axolotl

Developmental Dynamics, EarlyView.
Abstract Background The axolotl is a prominent model organism of heart regeneration due to its ability to anatomically and functionally repair the heart after an injury that mimics human myocardial infarction. In humans, such an injury leads to permanent scarring. Cardiac regeneration has been linked to metabolism and the oxygenation state, but so far,

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.
