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

Cell 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,

The pollination ecology and mouthpart morphology of a pollen‐feeding fly Incurviseta cf. maculifrons (Diptera: Lauxaniidae) in the Australian Alpine

Physiological Entomology, EarlyView.
The Lauxaniid fly Incurviseta cf. maculifrons (Malloch, 1925) is a locally abundant but poorly understood flower visitor in the Australian Alpine. We describe the flower visitation, pollen transport, pollen diet and mouthpart morphology of I. cf. maculifrons using field observations, pollen analyses and scanning electron microscopy. I. cf.

Prolonged exposure to artificial light and carcinogenesis: A systematic review of oncostatic mechanisms associated with melatonin pathways

Photochemistry and Photobiology, EarlyView.
Exposure to artificial light at night (ALAN), particularly at blue wavelengths, disrupts circadian rhythms by suppressing melatonin, thereby increasing cancer susceptibility. This systematic review consolidates evidence linking prolonged ALAN exposure to an elevated risk of breast and prostate tumors.

Long‐term stability of conventional non‐regenerative periodontal treatment for furcation defects

Periodontology 2000, EarlyView.
Abstract Background Furcation involvement (FI) in multi‐rooted teeth poses significant challenges in periodontal therapy due to complex anatomy and difficulty in achieving effective maintenance. FI is associated with increased periodontal destruction, especially in sites with narrow furcation entrances and deep root concavities.

Bacterial biofilm in salivary gland stones: Cause or consequence? [PDF]

, 2016
OBJECTIVE: The pathogenesis of salivary calculi is not yet clear; however, 2 theories have been formulated: (1) "the classic theory," based on calcium microdeposits in serous and ductal acinous cells, successively discharged into the ducts; (2) "the ...
