Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

The Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

Prediction of Relapse and Glucocorticoid Dependence in Eosinophilic Granulomatosis With Polyangiitis: Findings From a Large European Cohort

Arthritis &Rheumatology, EarlyView.
Objective Eosinophilic granulomatosis with polyangiitis (EGPA) is a small vessel vasculitis characterized by eosinophilia, asthma, and ear, nose, and throat (ENT) involvement. Although glucocorticoids (GCs) are effective in controlling symptoms, relapses and GC dependence are common. The aim of this study was to develop predictive models for vasculitis

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease

Arthritis &Rheumatology, EarlyView.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

Management of severe bone loss in patients at risk of medication‐related osteonecrosis of the jaw with microsurgery and guided bone regeneration: A case study

Clinical Advances in Periodontics, EarlyView.
Abstract Background Medication‐related osteonecrosis of the jaw (MRONJ) is a challenging complication associated with antiresorptive medications. Its exact pathophysiology remains unclear, but dental extractions and infections are known triggers, complicating prevention, and treatment.

Implant‐related orofacial pain managed with implant apicoectomy: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background In recent years, the use of implants has emerged as a widely accepted method for the replacement of missing teeth. Although rare, chronic pain associated with implant placement has been reported in the literature. Conversely, apicoectomy, the removal of the apical portion has been integrated into the implantology field in cases with
