Ferroptose‐induzierender Co(III) Polypyridin Sulfasalazin Komplex für die verbesserte Krebstherapie

open access: yesAngewandte Chemie, Volume 136, Issue 48, November 25, 2024.
Der gezielte Einsatz der Ferroptose ist ein neuer Weg, um die Grenzen der apoptotischen Krebsbekämpfung zu überwinden. Der hier beschriebene Co(III)‐Polypyridin‐Sulfasalazin‐Komplex wirkt als starker Ferroptose‐Induktor für die Krebstherapie. Dieser Komplex reichert sich selektiv in Mitochondrien an, wobei er reaktive Sauerstoffspezies erzeugt, die ...

Die Click‐to‐Release‐Aktivierung des Reserveantibiotikums Colistin am Zielort verringert dessen Nierentoxizität

open access: yesAngewandte Chemie, Volume 136, Issue 47, November 18, 2024.
Wir berichten, wie über eine Zwei‐Komponenten‐Strategie die starke Nierentoxizität des Antibiotikums Colistin verringert werden kann. Dazu werden nicht‐nephrotoxische trans‐Cycloocten‐Colistin‐Derivate durch das tetrazinverknüpfte, bakterienspezifische Peptid Ubiquicidin (29–41) über einen click‐to‐release‐Mechanismus aktiviert.

Enfortumab vedotin‐induced cutaneous eruption: Ring mitotic figures as a distinctive histopathologic feature

open access: yesJournal of Cutaneous Pathology, Volume 51, Issue 11, Page 847-851, November 2024.
Abstract Enfortumab vedotin (EV), a nectin‐4‐binding agent that affects microtubules, has become standard therapy for advanced urothelial carcinoma. The agent, now given in combination with pembrolizumab, frequently induces cutaneous reactions. Here, we report a severe EV‐induced cutaneous eruption.

Apoptose e expressão de Bcl-2 e das caspases 3 e 8 em placenta bovina, em diferentes estádios de gestação Apoptosis and expression of Bcl-2 and caspases 3 and 8 in placenta of cows at different pregnancy stages

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2010
Apoptose e seus mecanismos reguladores são eventos fisiológicos cruciais para a manutenção da homeostase placentária, e o desequilíbrio desses processos pode comprometer a função placentária e, consequentemente, o sucesso da gravidez.

Apoptose e maturação placentária bovina: um estudo imunohistoquímico e morfométrico

open access: yesPesquisa Veterinária Brasileira, 2016
Resumo: A liberação da placenta após o parto envolve a perda da adesão materno-fetal e ocorre somente após a maturação completa do placentoma, que está relacionada com a diminuição da celularidade dos tecidos fetal e materno. A apoptose é requerida tanto
