Peer-Assisted Learning vs Expert-Assisted Learning in Osteology: A Comparative Crossover Study in Medical Education

National Board of Examinations Journal of Medical Sciences
Background: Anatomy forms the structural foundation of medical education, and osteology is a core component of first year MBBS training. Despite its importance, osteology—particularly of the axial skeleton—is frequently perceived as difficult by students

Roles of Two F-Box Proteins: FBXL14 in the Periosteum and FBXW2 at Elastic Fibers

Osteology, 2023
I previously reported that F-box/leucine-rich repeat protein 14 (FBXL14) expressed in periosteum-derived cells, and F-box and WD-40 domain-containing protein 2 (FBXW2) in the periosteum form a fiber-like structure.

Sensory Nerve‐Derived CGRP Controls Osteoclastogenesis by Limiting Macrophage Bioenergetics in Bone Repair

Advanced Science, EarlyView.
Sensory nerves help bones heal. This study shows that the neuropeptide CGRP, released from sensory nerves, slows down macrophage energy production, preventing excessive bone breakdown. By revealing this nerve–immune–metabolism connection, the work provides new insight into how the body balances bone repair and opens doors to targeted treatments ...

Correlations Between Osteocyte Lacuno‐Canalicular Network and Material Characteristics in Healthy and Mechanically Stimulated Murine Tibiae

Advanced NanoBiomed Research, EarlyView.
This article reveals how calcium content, mineral nanostructure, and lacuno‐canalicular network (LCN) organization interact to shape bone heterogeneity in mouse tibiae. Advanced multimodal imaging uncovers that mechanical loading promotes mature mineral structures even in low‐calcium regions, highlighting LCN‐driven mineralization and offering new ...

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

The Anatomical Record, EarlyView.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Ontogenetic changes and sexual dimorphism in the cranium and mandible of the Atlantic walrus (Odobenus rosmarus rosmarus L.)

The Anatomical Record, EarlyView.
Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.

Rsk2 inhibition induces an aneuploid post-mitotic arrest of cell cycle progression in osteosarcoma cells

Cell Death Discovery
Osteosarcoma is the most common primary bone tumor, which is associated with a high mortality rate. The c-Fos transgenic mouse model has been described to spontaneously develop osteosarcoma, and the ribosomal S6 kinase 2 (Rsk2) was found to be essential ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

The Anatomical Record, EarlyView.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.
