Comparative morphology of the primate tongue.

Ann Anat 2019 Feb 6;223:19-31. Epub 2019 Feb 6.

Department of Anatomy, The Nippon Dental University School of Life Dentistry at Niigata, Niigata, Japan.

To clarify the role of the primate tongue as a means to better understand the evolution of oral function among primates - an example of adaptation within the restricted phylogenetic group - we review the morphological knowledge of the tongues of extant primates in relation to phylogenetic classification. Prosimians tongues are more effective than those of Haplorhini for taking up food with the tongue alone, because they are capable of fine movement when outside the oral cavity. However, the role of the tongue in food uptake has diminished when juxtaposed with progress in hand manipulation of food and tools in Haplorhini, especially with the manipulation of tools by Homininae.

Numerical investigations of bone remodelling around the mouse mandibular molar primordia.

Ann Anat 2018 Dec 30;222:146-152. Epub 2018 Dec 30.

Endowed Chair of Oral Technology, University of Bonn, Bonn, Germany.

The formation of the alveolar bone, which houses the dental primordia, and later the roots of tooth, may serve as a model to approach general questions of alveolar bone formation. In this respect, this study aimed to investigate the potential interactions between the alveolar bone formation and tooth eruption by using finite element (FE) methods, and to figure out whether the expanding tooth systems induce shear stresses that lead to alveolar bone formation. 3D geometric surface models were generated from the 3D histological data of the heads of mice (C57 Bl/6J) ranging from stages embryonic (E) to postnatal (P) stages E15 to P20 using the reconstruction software 3-Matic.

Role of HSP70 protein in human periodontal ligament cell function and physiology.

Ann Anat 2019 Jan 22;221:76-83. Epub 2018 Sep 22.

Department of Orthodontics, Dental Clinic, University of Bonn, Germany.

Objective: Heat pre-treatment of mechanically loaded human periodontal ligament cells (hPDL) dampens the inflammatory cellular response, as evidenced by a reduced expression of pro-inflammatory cytokines, inhibition of monocyte adhesion and osteoclastic differentiation. These findings imply heat shock proteins (HSP) as cell protective molecules acting in the PDL that are up-regulated upon ischemia caused by mechanical loading. HSP70 and its inhibition by VER155008 as the active agent in several pharmaceuticals are established targets and strategies, respectively, in the treatment of neoproliferative diseases. Read More

Lymphatic vessels of the eye - old questions - new insights.

Ann Anat 2019 Jan 18;221:1-16. Epub 2018 Sep 18.

Klinik für Augenheilkunde, Universitätsklinikum Düsseldorf, Heinrich Heine Universität Düsseldorf, Moorenstrasse 5, 40225 Düsseldorf, Germany.

Due to its accessible position and tissue heterogeneity, the eye is ideally suited for studying the lymphatic system. As early as the 19th century, questions about the origin and function of this system were discussed. For example, whether Schlemm's canal, which is of particular importance in the pathogenesis of glaucoma, is a lymphatic vessel, or does this vascular system begin with finger-shaped protuberances? Despite the discovery of lymphatic endothelial molecules and the use of molecular imaging technologies, these questions are still discussed controversially today. Read More
