Nyctereutes terblanchei: The raccoon dog that never was [PDF]

, 2012
Fossils of the raccoon dog (genus Nyctereutes) are particularly rare in the African PlioPleistocene record, whilst the sole living representative, Nyctereutes procyonoides, is found in eastern Asia and parts of Europe. In southern Africa, only one fossil

Biomimetic Mineralization of Keratin Scaffolds for Enamel Regeneration

Advanced Healthcare Materials, EarlyView.
Keratin‐based films guide biomimetic enamel remineralization by promoting organized hydroxyapatite growth under physiological conditions. Advanced biophysical characterization confirms keratin's structural adaptability and mineral ions‐binding affinity, supporting mineral nucleation and hierarchical crystal assembly. This study establishes keratin as a

Metronidazole‐Loaded Cyclodextrin Nanogels for Antibacterial Therapy and Microbiota Regulation in Periodontitis

Advanced Healthcare Materials, EarlyView.
A methacrylamide β‐cyclodextrin‐based nanogel (MACD nGel) is developed to load the antimicrobial drug Metronidazole (MNZ) for topical delivery for the treatment of periodontitis. It is demonstrated that cyclodextrin nanogel (nGel) loaded with metronidazole provides an efficient drug delivery route but also has potential clinical applications and offers

Biometric analysis of the dental arches and teeth position in partially edentulous patients

Zaporožskij Medicinskij Žurnal, 2020
An edentulous state often causes changes in the dental arch shape first in the defect area, and then spreads to the entire dental arch. Secondary deformities of the tooth arches, which occur during pathological displacement of individual teeth ...

Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

Advanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

Genetic and environmental determinants of dental occlusal variation in South Australian twins

Australasian Orthodontic Journal, 1998
As part of an ongoing study of dentofacial morphology in South Australian twins, several occlusal traits were compared between forty eight monozygous and thirty four dizygous twin pairs, as well as estimating genetic variances for these features ...
