Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Evaluation of Partial Volume Correction Techniques for Sodium MRI of the Achilles Tendon

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2180-2193, April 2026.
ABSTRACT Purpose To evaluate partial volume correction (PVC) techniques for sodium MRI of the Achilles tendon in situ and in vivo. Methods Five PVC methods were evaluated including a volume ratio of the proton and sodium segmentations (PSSR), a modified least trimmed square (3D‐mLTS) linear regression, a geometric transfer matrix (GTM) approach, a ...

A wireless acquisition system for monitoring the influence of loads on vertebral column behaviour [PDF]

, 2008
This paper presents a wireless acquisition module (WAM). This allows the monitoring of heavy loads influence on vertebral column’s behaviour. Each module makes the electromyography (EMG), to measure the electric potentials on the iliocostalis and ...

Complex Mechanical Loading and Pro‐Inflammatory Cytokines in Intervertebral Disc Degeneration

JOR SPINE, Volume 9, Issue 1, March 2026.
This study investigated the combined effects of dynamic compression and torsion with major pro‐catabolic cytokine interleukin‐1 beta (IL‐1β) and its inhibitor: interleukin‐1 receptor antagonist (IL‐1Ra), on bovine IVD in an ex vivo organ culture system and further evaluated the mechanical effects using a subject‐personalized finite element model based ...

Influence of the Intervertebral Disc Microenvironment on Matrix Synthesis and Metabolism in Goat Nucleus Pulposus Cells

JOR SPINE, Volume 9, Issue 1, March 2026.
Goat nucleus pulposus cells cultured under clinically relevant oxygen, glucose, pH, and osmolarity revealed pH to have the most influential impact on viability and glycosaminoglycan synthesis. Interactions between factors showed that disc cell behavior is shaped by the microenvironment, highlighting its importance in regenerative therapy design for the

Interacting Active Rectangles for Estimation of Intervertebral Disk Orientation [PDF]

, 2008
This paper presents a fast and efficient method to determine intervertebral disk orientation in a magnetic resonance (MR) image of the spine. The algorithm originates from active contour theory and enforces a shape constraint to avoid leaks through weak ...

Biomechanical Effects of Different Approaches and Titanium Mesh in Combined Anterior Cervical Corpectomy Decompression and Fusion: A Finite Element Study

Engineering Reports, Volume 8, Issue 2, February 2026.
Equivalent stress cloud maps of cervical spine flexion movement after four anterior approach methods. (a) VBSP‐S method. (b) AVBSP‐C method. (c) APSP‐S method. (d) APSP‐C method. ACCF biomechanics depend on fixation (AVBSP/APSP) and mesh shape (linear/curved). Adjacent disc sensitivity varies. Fixation choice affects titanium mesh stress.

Synaptic Vesicle Glycoprotein 2A Suppresses Amyloidogenesis Beyond Its Synaptic Role: A Novel Mechanism Disrupting BACE1 Binding and Altering APP Localization

Aging Cell, Volume 25, Issue 2, February 2026.
Synaptic vesicle glycoprotein 2A, the newly identified APP‐binding protein, reduces amyloid‐β plaque deposition in Alzheimer's disease by suppressing the amyloidogenic pathway through inhibition of BACE1‐APP interaction and alteration of APP endosomal‐lysosomal localization.

Correlation of radiographic and MRI parameters to morphological and biochemical assessment of intervertebral disc degeneration [PDF]

, 2018
Degenerative disc disease (DDD) is a common finding in MRI scans and X-rays. However, their correlation to morphological and biochemical changes is not well established.
