Alveolar bone remodeling following orthodontic closure of missing mandibular first molar spaces: a CBCT-based morphometric study

Progress in Orthodontics
Background Loss of the mandibular first molar is a common and detrimental clinical issue that often leads to alveolar bone resorption in the edentulous area, complicating future prosthetic or orthodontic interventions.

Developmental differences in cortical bone structure in chimpanzee and human femora reflect early locomotor independence in humans

The Anatomical Record, EarlyView.
Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

Table_1_The Injectable Woven Bone-Like Hydrogel to Perform Alveolar Ridge Preservation With Adapted Remodeling Performance After Tooth Extraction.DOCX

, 2020
Grafting bone substitute is paramount to prevent the alveolar ridge resorption after tooth extraction and facilitate the subsequent implant treatment. An ideal bone substitute should acquire the excellent osteogenic property, more importantly, possess ...

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Redescription of the cranial morphology of Amphisbaena braestrupi and Amphisbaena laurenti (Squamata: Amphisbaenidae) from the Pleistocene of Brazil using x‐ray computed tomography

The Anatomical Record, EarlyView.
Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena braestrupi and Amphisbaena laurenti from the Pleistocene of Lagoa Santa ...

Mechanical Stress Regulates Alveolar Bone Remodeling Via Neat1-Induced Lymphangiogenesis

International Dental Journal
Aim or purpose: This study investigates the role of mechanical stress in alveolar bone remodeling through lymphangiogenesis, focusing on the involvement of periodontal ligament stem cells (PDLSCs) and the lncRNA NEAT1 in regulating the VEGFC/FLT4 ...

Biomechanical strain patterns in Meckel's cartilage underlie mandibular variation in FGFR2 mouse models

The Anatomical Record, EarlyView.
Abstract Sequence variations in fibroblast growth factor receptor 2 (FGFR2) are associated with craniosynostosis syndromes, disrupting craniofacial development, yet early mandibular alterations remain poorly characterized. This study examined Meckel's cartilage (MC) and mandibular morphology in mouse models of Apert (Fgfr2+/P253R) and Crouzon ...

Dual Effects of β‐TrCP2 Deletion in Bone Homeostasis: Suppression of Osteoclastogenesis and Enhancement of Osteoblast Activity

Arthritis &Rheumatology, EarlyView.
Objective The aim of this study was to elucidate the role of beta‐transducin repeat‐containing protein 2 (β‐TrCP2) in bone homeostasis for its potential as a therapeutic target for osteoporosis. Methods The role of β‐TrCP2 in bone phenotypes was investigated using systemic β‐TrCP1 knockout (KO) and β‐TrCP2KO mice, along with myeloid‐specific ...

Extracellular Vesicles‐Based Biological Macromolecule Delivery Systems: Biogenesis, Characterization, and Emerging Clinical Applications

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are nanoscale membrane‐bound structures that play a pivotal role in intercellular communication by transporting bioactive molecules, including proteins, lipids, nucleic acids, and organelles, between cells. Originating from the endosomal pathway, EVs reflect the physiological and pathological status of their parent
