A New Concept of Mosaicplasty: Autologous Osteoperiosteal Cylinder Graft Covered With Cellularized Scaffold. [PDF]

open access: yesArthrosc Tech, 2022
Abstract A concern regarding osteochondral autograft transfer for chondral defects is donor‐site morbidity of the knee, the most common source of the autograft. To avoid the drawbacks of osteochondral autograft transfer, a cylindrical osteoperiosteal graft harvested from the iliac crest covered by a same‐sized cylinder of hyaluronic acid–based polymer ...

Conditioned serum in vitro treatment of chondrocyte pellets and osteoarthritic explants. [PDF]

open access: yesEquine Vet J, 2023
Abstract Background Autologous conditioned serum (ACS) is used to treat osteoarthritis in horses, although its effects are not fully investigated. Objectives To investigate the effects of equine serum and conditioned serum on chondrocytes stimulated with interleukin (IL)‐1β and cartilage explants with mild osteoarthritis.

Inhibition of SDF-1/CXCR4 Axis to Alleviate Abnormal Bone Formation and Angiogenesis Could Improve the Subchondral Bone Microenvironment in Osteoarthritis. [PDF]

open access: yesBiomed Res Int, 2021
The pathogenesis of the osteoarthritis (OA) is complex. Abnormal subchondral bone metabolism is an important cause of this disease. Further understanding on the pathology of the subchondral bone in OA may provide a new therapy. This research is about to investigate the role of SDF‐1 in the subchondral bone during the pathological process of OA.

Morphological Investigation of the Roe Deer (Capreolus capreolus) Os Hyoideum and Creating a 3D Model. [PDF]

open access: yesVet Med Sci
With this study, detailed morphological, morphometric and 3D printing data of the roe deer os hyoideum were obtained for the first time and its similarities and differences with other animal species were compared. The os hyoideum consisted of six parts, but the processus lingualis, which is found in ruminants, was not present in the roe deer.

A survey of the uncinate bone and other poorly known ossicles associated with the lacrimal/ectethmoid complex of the avian skull

open access: yesThe Anatomical Record, Volume 305, Issue 9, Page 2312-2330, September 2022., 2022
Abstract In several taxa of Neornithes (crown group birds), the lacrimal/ectethmoid complex exhibits small bones, the comparative osteology of which is poorly studied. Some of these ossicles—which are commonly known as uncinate bones (ossa uncinata or ossa lacrimopalatina)—were already described two centuries ago, but knowledge of their distribution ...

Rheumatoid arthritis: Development after the emergence of a chemokine for neutrophils in the synovium

open access: yesBioEssays, Volume 43, Issue 10, October 2021., 2021
Events before synoviocyte (purple spindles) proliferation. In the beginning, CXCL5 (red rectangle) is produced by synoviocytes, followed consecutively by neutrophils (N) and monocyte (M) recruitment, IL‐17A secretion, CCL20 (yellow rectangles) expression, recruitment of CCR6‐expressing cells (dark brown circles), secretion of many chemokines (gray‐ and

Digital dissection of the head of the frogs Calyptocephalella gayi and Leptodactylus pentadactylus with emphasis on the feeding apparatus

open access: yesJournal of Anatomy, Volume 239, Issue 2, Page 391-404, August 2021., 2021
Our study presents MicroCT‐scans of two frog species in order to reconstruct the complete anatomical condition of the whole feeding apparatus for the first time. The figure depicts a sagittal section through the heads of Calyptocephalella gayi (A) and Leptodactylus pentadactylus (B). Abstract Micro‐computed tomography (microCT) of small animals has led

The tadpoles of the funnel‐mouthed dendrobatids (Anura: Dendrobatidae: Colostethinae: Silverstoneia): external morphology, musculoskeletal anatomy, buccopharyngeal cavity, and new synapomorphies

open access: yesJournal of Zoological Systematics and Evolutionary Research, Volume 59, Issue 3, Page 691-717, April 2021., 2021
After describing the external, buccopharyngeal, muscle, and chondrocranium morphology of the funnel‐mouthed dendrobatid tadpoles of the genus Silverstoneia and their relatives, we delimited 16 new larval characters, including 12 new synapomorphies for the genus.

Savannah roars: The vocal anatomy and the impressive rutting calls of male impala (Aepyceros melampus) – highlighting the acoustic correlates of a mobile larynx

open access: yesJournal of Anatomy, Volume 236, Issue 3, Page 398-424, March 2020., 2020
Male impala retract the larynx while producing their impressive rutting roars. The low fundamental frequency of these roars is produced by a highly modified vocal fold, a ‘vocal keel’. The anatomical and acoustical correlates of male impala's mobile larynx are discussed.

Convergence and functional evolution of longirostry in crocodylomorphs

open access: yesPalaeontology, Volume 62, Issue 6, Page 867-887, November 2019., 2019
Abstract During the Mesozoic, Crocodylomorpha had a much higher taxonomic and morphological diversity than today. Members of one particularly successful clade, Thalattosuchia, are well‐known for being longirostrine: having long, slender snouts. It has generally been assumed that Thalattosuchia owed their success in part to the evolution of longirostry,
