Bio-Based Bisbenzoxazines with Flame Retardant Linker.

Polymers

Haubold TS, Puchot L, Adjaoud A, Verge P, Koschek K.
PMID: 34960884
Polymers (Basel). 2021 Dec 10;13(24). doi: 10.3390/polym13244330.

This work explores the strategy of incorporating a highly substituted reactive flame retardant into a benzoxazine moiety. For this purpose, a DOPO-based flame retardant received a chain extension via reaction with ethylene carbonate. It was then reacted with phloretic...

Role of extracellular calcium and calcium stores in the intracellular calcium rise induced by diethylstilboestrol in C6 rat glioma cells.

Toxicology in vitro : an international journal published in association with BIBRA

Tas P, Ambs S, Stopper H, Koschel K, Schiffmann D.
PMID: 20650070
Toxicol In Vitro. 1995 Apr;9(2):117-21. doi: 10.1016/0887-2333(94)00203-7.

The aneuploidy-inducing carcinogenic oestrogen diethylstilboestrol (DES) causes an elevation of the cytoplasmic Ca(2+) concentration of C6 rat glioma cells. It is known that the intracellular calcium concentration is a critical factor in mitosis. DES induces mitotic disturbances resulting in...
