Sprint‐interval training with post‐exercise blood flow restriction increases mitochondrial content and respiration

The Journal of Physiology, EarlyView.
Abstract figure legend The mechanisms underpinning improved maximal oxygen uptake following sprint interval training (SIT) with post‐exercise blood flow restriction (BFR), compared to SIT alone, remain unclear. This study examined the effects of 6 week SIT with (BFR; n = 12) or without (CON; n = 8) post‐exercise BFR on V̇O2peak${{\dot{V}}_{{{{\mathrm{O}

Geminale Difunktionalisierung von Ketonen durch C–S Bindungs‐insertion photogenerierter Donor–Donor Diazoverbindungen

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Die geminale Difunktionalisierung leicht verfügbarer Bausteine ermöglicht einen schnellen Zugang zu molekularer Komplexität. Diese Arbeit stellt eine Strategie vor, um zwei unterschiedliche funktionelle Gruppen an einem Carbonylkohlenstoff zu installieren, indem dieser in eine Donor–Donor‐Diazo‐Verbindung überführt wird. Die Methode ist sowohl im Batch‐

Geminal Difunctionalization of Ketones via C─S Bond Insertion of Photogenerated Donor–Donor Diazo Compounds

Angewandte Chemie International Edition, Volume 65, Issue 25, 15 June 2026.
Geminal difunctionalization of readily available building blocks provides rapid access to molecular complexity. This work introduces a strategy for installing two distinct functional groups on a carbonyl carbon by transforming it into a donor–donor diazo compound, enabling both batch and flow applications with broad solvent compatibility.
