Muscle mitochondria in sepsis

, 2006
Patients treated in the intensive care unit (ICU) for sepsis induced multiple organ failure often suffer from skeletal muscle fatigue after ICU discharge. Since mitochondria are the main determinants of muscle fatigability, their function in muscle of these patients was the theme of this thesis.

BIOCHEMICAL STUDIES ON THE MUSCLE MITOCHONDRIA

The KITAKANTO Medical Journal, 1959
The author has studied some biochemical and morphological properties of mitochondria of several kinds of muscle, chiefly giant mitochondria of flight muscle of dragon fly. The results were as follows;1) Giant mitochondria of flight muscle of dragon fly were situated on the A band region of myofibrils, and neither A substance nor I substance could be ...

Precision Nanomedicine for Traumatic Neural Injury: Functional Paradigms and Translational Frameworks

Advanced Science, EarlyView.
This review presents a pathology‐driven framework unifying nanomedicine across TBI, SCI, and PNI. Epidemiological evidence and comparative single‐cell transcriptomic reanalysis define shared pathological modules, injury‐specific effectors, and therapeutic bottlenecks. Six functional paradigms connect nanomaterial structure and biological fate to injury‐

Mitochondrial Quality Control in Degenerative Musculoskeletal Diseases: Signaling Networks and Therapeutic Landscapes

Advanced Science, EarlyView.
Mitochondrial quality control (MQC) collapse redefines osteoarthritis, intervertebral disc degeneration, and osteoporosis as disorders of organelle dysfunction. Damaged mitochondria leak mtDNA and metabolites, driving cGAS‐STING inflammation, epigenetic reprogramming, and metabolic memory.

A Biomimetic PLK1 Nanodelivery System Promotes Migrasome‐Mediated Mitocytosis to Restore Efferocytosis and Functional Recovery After Spinal Cord Injury

Advanced Science, EarlyView.
MM‐NPs@PLK1 are formed by encapsulating PLK1 plasmids within CBP5 and coating the nanocomplexes with macrophage membranes. After macrophage‐associated uptake, the NPs@PLK1 enter the cytoplasm and release the PLK1‐encoding plasmid in response to elevated intracellular ROS levels.

Astrocytic Ketogenesis Protects Central Nervous System Injury via CPT1A Stabilization and Epigenetic Regulation

Advanced Science, EarlyView.
A distinct astrocyte subpopulation, enriched at the lesion border, drives CNS repair through enhanced ketone body metabolism. This process promotes neuronal survival and axonal sparing via CPT1A stabilization and H3K9bhb‐dependent epigenetic reprogramming, positioning astrocytic ketogenesis as a promising therapeutic target for tissue regeneration ...

ALDH2 Suppresses Ferroptosis and Promotes Bortezomib Resistance in Multiple Myeloma Through the KEAP1‐NRF2 Feedback Loop

Advanced Science, EarlyView.
ALDH2, which is overexpressed in multiple myeloma, competitively binds KEAP1 to stabilize NRF2 by blocking its ubiquitin‐proteasomal degradation. Stabilized NRF2 translocates into the nucleus to upregulate the expression of GPX4. In parallel, NRF2 binds to the ALDH2 promoter to regulate its transcription, forming a positive feedback loop that represses

Lithium‐Doped Hydroxyapatite Nanowires Rejuvenate Senescent Macrophages Via the Lysosome‐Dependent Ferroptosis Axis to Promote Aged Bone Regeneration

Advanced Science, EarlyView.
Li‐nHAP+GelMA promotes mandibular bone regeneration in aged mice by remodeling the senescent immune microenvironment. Local delivery of Li‐nHAP restores lysosomal homeostasis in senescent macrophages, reduces intracellular labile Fe2+ accumulation, ROS production, and lipid peroxidation, thereby suppressing macrophage ferroptosis and senescence ...

Mitochondrial fusion and altered beta-oxidation drive muscle wasting in a Drosophila cachexia model

EMBO Reports
Cancer cachexia is a tumour-induced wasting syndrome, characterised by extreme loss of skeletal muscle. Defective mitochondria can contribute to muscle wasting; however, the underlying mechanisms remain unclear.
