Taxonomic and functional diversity of benthic foraminifera as a promising proxy for tidewater glacier retreat

open access: yesBoreas, EarlyView.
Ice sheets and glaciers globally are losing mass at increasing rates, with the strongest changes occurring at tidewater glaciers. These are rapidly retreating and often transitioning to land‐terminating with implications for sea level change and ecosystem functioning.

The Effect of Crown Height and Retentive Height of Abutment on the Fracture Resistance of Fatigued Monolithic Zirconia Anterior Implant Crowns—An In Vitro Study

open access: yesClinical Oral Implants Research, EarlyView.
ABSTRACT Objectives This laboratory study investigated the effect of two different retentive heights of Ti‐base abutments (3.5 and 5.5 mm) and crown heights (13 and 16 mm) on the load at failure and survival of monolithic zirconia implant‐supported crowns replacing a maxillary central incisor.

Hypoxia Exacerbates Periapical Periodontitis‐Associated Pathological Bone Loss via the Hypoxia‐Inducible Factor‐2α‐Calmodulin‐Dependent Protein Kinase IV Axis

open access: yesCell Proliferation, EarlyView.
Hypoxia exposure activates HIF‐2α, which binds to the Camk4 promoter to enhance RANKL‐mediated osteoclast differentiation, leading to aggravated alveolar bone resorption in periapical periodontitis. ABSTRACT Periapical periodontitis is one of the most common inflammatory bone destructive diseases. Epidemiological evidence suggests that hypoxia exposure,
