Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Force-induced increased osteogenesis enables accelerated orthodontic tooth movement in ovariectomized rats

Scientific Reports, 2017
As the number of elderly orthodontic patients increases, the impact of postmenopausal osteoporosis on orthodontic tooth movement (OTM) has attracted a great deal of attention because OTM relies on alveolar bone remodeling.

The study on PAOO minimally invasive versus traditional surgery in accelerating orthodontic tooth movement and its mechanisms [PDF]

Kouqiang yixue
Objective To compare the periodontally accelerated osteogenic orthodontics(PAOO) effects of corticotomy with full mucoperiosteal flap(flapped corticotomy) and corticotomy-only on accelerating orthodontic tooth movement. Methods A total of 60 healthy male

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.

Craniofacial growth, modeling, and estimation of milestones

The Anatomical Record, EarlyView.
Abstract Understanding craniofacial growth is foundational for research into intra‐ and interspecies variation, evolution, and clinical care. The Craniofacial Growth Consortium Study (CGCS), combines cephalographs from historical growth studies to create a dense longitudinal record of growth from 6 to 22 years of age.

Extracorporeal shockwave treatment impedes tooth movement in rats

Head & Face Medicine, 2018
Background Accelerated tooth movement has been a topic of interest for orthodontic research recently. Surgically facilitated orthodontic treatment has been shown to be an effective approach to accelerate tooth movement; however, it remains invasive ...

Arthroscopic Remplissage With Knotless All‐Suture Anchors and Concomitant Bankart Repair: Technical Considerations

Arthroscopy Techniques, EarlyView.
Abstract Anterior shoulder instability is common in active patients. Traumatic dislocations may produce Bankart and Hill‐Sachs lesions that increase recurrence risk. In high‐demand individuals, isolated Bankart repair may be insufficient for off‐track or near‐track Hill‐Sachs lesions.

Targeting neutrophil extracellular traps in metabolic and immune niche: Nanomaterials for diabetes tissue regeneration

BMEMat, EarlyView.
The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.

Effect of autophagy on aging-related changes in orthodontic tooth movement in rats

BMC Oral Health
Background The number of adult orthodontic patients is increasing, and studies have shown that autophagy is involved in regulating orthodontic tooth movement and plays an important role in aging-related changes. Therefore, we aimed to explore the role of
