Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level
Aging and Cancer, EarlyView.This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
Advanced Functional Materials, EarlyView.The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

ROOT CANAL MORPHOLOGY; CONCEPT IN MANDIBULAR 3RD MOLAR BY CONVENTIONALLY ENDODONTIC TREATMENT
THE PROFESSIONAL MEDICAL JOURNAL, 2017 Morphological features of mandibular 3rd molar are always unpredictable, andshow a discrepancy by way of different individual. Nevertheless, restorative, prosthetic andorthodontic concerns of these mandibular third molars require root canal treatment in turn topreserve functional elements in the jaw.

An endodontic management of mandibular third molar with five root canals
Saudi Endodontic Journal, 2014 The existence of several anatomical variations in the root canal system may contribute to failure of the root canal therapy. The planning and performing of endodontic therapy requires knowledge of the internal dental morphology.

Root Canal Morphology of Mandibular Primary Molars: A Micro-CT Study [PDF]
, 2019 Objectives: Frequency of typical and non-typical root and canal morphology of primary teeth, which in clinical practice cannot be detected using 2D radiographic images, should be known by clinicians to decrease failures arising from complexity of root ...

Advanced Healthcare Materials, EarlyView.Mineralization alone does not establish a mature bone organoid. This Review integrates biological foundations, materials design, adaptive remodeling, and translational validation through the development‐to‐remodeling continuum (DRC). By separating biological functions from the evidence supporting them, the framework exposes critical gaps in current ...
