Angewandte Chemie, EarlyView.O2 verbessert den Ladungstransfer in organischen n‐Typ‐Donor‐Akzeptor‐Ladungstransferkomplexen (CTCs) durch physisorptive Passivierung von Ladungsträgerfallen. Durch die Unterdrückung der Rekombination und die Förderung langlebiger delokalisierter Ladungsträger verbessert O2 den Elektronentransport und die Leitfähigkeit ohne Dotierung.

Angewandte Chemie, EarlyView.Vitamin D entfaltet über die Aktivierung des ligandenabhängigen Transkriptionsfaktors Vitamin‐D‐Rezeptor (VDR) komplexe und zellspezifische biologische Wirkungen in verschiedenen Geweben. Das photoschaltbare Vitamin‐D‐Mimetikum 10 wechselt durch Belichtung zwischen VDR‐Antagonisten‐ (E) und Agonisten‐Aktivität (Z) und bietet eine bislang einzigartige ...

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment
The Anatomical Record, EarlyView.Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

The Anatomical Record, EarlyView.Abstract Sexual differentiation in the equine fetus involves coordinated morphogenetic processes that shape both the gonads and the genital ducts. Although the formation of testes and ovaries has been relatively well documented, the temporal dynamics and morphometric patterns of the mesonephric (Wolffian) and paramesonephric (Müllerian) ducts remain ...

Multiparametric ultrasonography of the pediatric scrotum and in boys with undescended testes
, 2013 Due to its noninvasiveness and high resolving power, ultrasound examination is the examination of choice for the imaging of the structures of the pediatric scrotum. It allows to reveal changes impossible to find in the course of a clinical examination.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates
The Anatomical Record, EarlyView.Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.
