Variation and development of the turtle chondrocranium, with a description of the common musk turtle (Sternotherus odoratus, Kinosternidae, Cryptodira, Testudines)

The Anatomical Record, Volume 308, Issue 7, Page 1994-2037, July 2025.
Abstract Based on histological cross‐sections, the chondrocranium of the common musk turtle (Sternotherus odoratus) was reconstructed, described, and compared with other turtles. It differs from that of other turtle chondrocrania by possessing elongated, slightly dorsally orientated nasal capsules with three dorsolateral foramina, which might be ...

The Inter‐Cratonic Neoproterozoic Katangan Basin of Central Africa: Rift Basin Formation, Orogenic Inversion and Potential Fluid Pathways

Tectonics, Volume 44, Issue 7, July 2025.
Abstract The tectono‐stratigraphic development of continental basins is critical to an understanding of continental tectonics and the formation of metal deposits. The Neoproterozoic, inter‐cratonic Katangan copper basin of Central Africa records a tectono‐stratigraphic evolution and the generation of potential metal transporting fluid pathways ...

Synthesis and Characterization of A3[ReO4][ReO3N] and A′2[ReO3N] (A = Rb, Cs; A′ = K, Cs)

European Journal of Inorganic Chemistry, Volume 28, Issue 17, June 17, 2025.
Various new nitridotrioxidorhenate compounds were successfully obtained via flux syntheses. By employing different equivalents of ammonium salts as a nitrogen source, it is possible to incorporate different amounts of nitrogen into perrhenates. Four new structures namely Rb3[ReO4][ReO3N], Cs3[ReO4][ReO3N], K2[ReO3N], and Cs2[ReO3N]—were elucidated and ...

A Rare Case of Intramediastinal Humeral Head Fracture Dislocation Through the Thoracic Inlet

Clinical Case Reports, Volume 13, Issue 4, April 2025.
ABSTRACT Intramediastinal fracture dislocation of the humeral head due to a blunt trauma is very rare. It may be accompanied by local and systemic injuries associated with high‐energy trauma. Only one case has been reported in the literature; therefore, an appropriate treatment modality remains unclear. We present a case of a 71‐year‐old woman involved
