Morphological diversity of saber‐tooth upper canines and its functional implications
The Anatomical Record, EarlyView.Abstract Elongated upper canine teeth, commonly known as saber‐teeth, have evolved three times within the sub‐order Feliformia. The species that wielded them flourished throughout the Cenozoic and have historically been separated into two morphological groups: the dirk‐tooths with longer, flatter canines, and the scimitar‐tooths with shorter, serrated ...

Reassessment of Xenodens calminechari with a discussion of tooth morphology in mosasaurs
The Anatomical Record, EarlyView.Abstract Xenodens calminechari is a mosasaurid taxon named by Longrich et al. (2021) based on the holotype MHNM.KH.331, a left maxilla with several teeth. This holotype was obtained nonscientifically (without technical supervision) from an area in Morocco that yields many manipulated or forged specimens. Examination of Longrich et al.

Tibial Implant Fixation in TKA Worth A Revision? -- How to Avoid Stress-Shielding Even for Stiff Metallic Implants [PDF]
arXiv, 2019 In total knee arthroplasty (TKA) force is transmitted into the tibia by a combined plate-stem device along with cemented or cementless stem fixation. The present work analyzes this force transmission in finite element simulations with the main aim to avoid reported postsurgical bone density reduction as a consequence of a reduced tibial bone loading ...

Acta orthopaedica. Supplementum, 2010 Acrylic bone cements are in extensive use in joint replacement surgery. They are weight bearing and load transferring in the bone-cement-prosthesis complex and therefore, inter alia, their mechanical properties are deemed to be crucial for the overall ...

The Anatomical Record, EarlyView.Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

China shares fossil treasures with the world
The Anatomical Record, EarlyView.Abstract China has been a rich source of fossils for nearly a century, beginning with the discovery of so‐called Peking man (Sinanthropus pekinensis), known today as Homo erectus pekinensis in the mid 1920s. The first Chinese dinosaurs were described in 1929, the sauropod Helopus (now Euhelopus) and the ornithopod Tanius, described by the Swedish ...
