Heat‐ and Light‐Directed Cycloadditions Enable a Pericyclic Cascade Reaction From a Molecular Precursor

Angewandte Chemie, EarlyView.
A multi‐stimuli‐responsive material is designed that responds to light, heat, and mechanical force through distinct chemical reaction pathways. The pathway is directed by self‐assembly and the applied stimulus. A novel pericyclic reaction cascade is also achieved, and the mechanism is supported through density functional theory calculations.

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

An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation

The Anatomical Record, EarlyView.
Abstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood. In particular, striking cranial adornments such as the postorbital horns and parietal‐squamosal frill of Triceratops ...

Ursolic Acid Alleviates Orchitis via Modulating Ferroptosis in Peritubular Myoid Cells of Testis

Animal Research and One Health, EarlyView.
Ursolic acid modulates key ferroptosis‐related pathways in the peritubular myoid cells of the testis in forest musk deer. ABSTRACT Chronic stress adversely affects reproductive health, increasing susceptibility to pathologies such as orchitis. Additionally, the maintenance of iron homeostasis is essential for preserving the function of the testicles ...
