Relationship between vitamin D deficiency and early implant failure and osseointegration

Periodontology 2000, EarlyView.
Abstract Background This systematic review investigated the relationship between pre‐operative vitamin D levels and implant osseointegration and implant‐related outcomes. It also assessed studies involving vitamin D supplementation before implant placement.

Understanding exosomes in facial esthetics and skin aging

Periodontology 2000, EarlyView.
Abstract Background Skin aging is a multifactorial process mediated by intrinsic (genetic and metabolic) and extrinsic (environmental) factors leading to functional and structural deterioration, including wrinkles, loss of collagen and elastin, as well as various pigmentation disorders.

Understanding exosomes in regenerative dentistry

Periodontology 2000, EarlyView.
Abstract Background Regenerative dentistry is shifting from cell‐based strategies to cell‐free biologics capable of orchestrating intricate tissue repair. Exosomes, nanosized extracellular vesicles carrying bioactive molecular payloads, have emerged as central modulators of intercellular communication.

Understanding extracellular vesicle biology, isolation, and characterization: The theory of EV‐erything

Periodontology 2000, EarlyView.
Abstract Background Extracellular vesicles (EVs), especially exosomes, are nanoparticles increasingly recognized as key regulators of intercellular communication in both physiological and pathological aspects. Despite rapid progress, inconsistencies in nomenclature, isolation, and characterization continue to restrict translational advancement.

Intersex Across the Interstellar: The Andromeda Constellation in Medieval and Early Modern Astronomical and Astrological Treatises

Renaissance Studies, EarlyView.
ABSTRACT This article examines the iconography of the Andromeda constellation as an intersex figure within medieval and early modern astrological traditions. It focuses on the origins of this imagery in the thirteenth‐century astrological writings of Scot and its reappearance nearly three centuries later in Ratdolt's illustrated 1482 edition of Hyginus'
