Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

The Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance

The challenge of translating ischemic conditioning from animal models to humans: the role of comorbidities

Disease Models & Mechanisms, 2014
Following a period of ischemia (local restriction of blood supply to a tissue), the restoration of blood supply to the affected area causes significant tissue damage.

Crossing the Blood–Brain Barrier with Molecularly Imprinted Polymeric Nanocarriers: An Emerging Frontier in Brain Disease Therapy

Advanced Science, Volume 13, Issue 7, 3 February 2026.
Molecularly imprinted polymeric nanocarriers (nanoMIPs) offer robust, antibody‐mimetic platforms to overcome the blood‐brain barrier. The article surveys nanoMIP design and ligand‐directed surface engineering that harness receptor‐mediated transcytosis, and highlights therapeutic and diagnostic applications in neurodegeneration, brain tumors and ...

New Insights on Heat Shock Proteins as Regulators of Reactive Oxygen Species Across Various Stressors in Diseases

Cell Biochemistry and Function, Volume 44, Issue 2, February 2026.
ABSTRACT Living beings are persistently challenged by stress. Stress can be induced by internal stressors and external stressors. External stressors, including radiation, heat, heavy metals, nutritional imbalances, infections, and psychological stress, can induce protein denaturation, leading to misfolded or aggregated proteins.

Mitochondrial Transporter ABCB10 Protects Against Doxorubicin‐Induced Respiratory Muscle Dysfunction Independent of Changes to Diaphragm Accumulation

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 1, February 2026.
ABSTRACT Background Doxorubicin (DOX) is a highly effective chemotherapeutic agent whose use can cause respiratory toxicity, increasing patient fatigue and negatively impacting quality of life and survival. These adverse effects occur due to diaphragm muscle mitochondrial accumulation of DOX, where it causes reactive oxygen species production and iron ...

Mitochondrial Intercellular Transfer via Platelets After Physical Training Exerts Neuro‐Glial Protection Against Cerebral Ischemia

MedComm, Volume 7, Issue 2, February 2026.
Treadmill training protects against white matter injury and reduces cerebral infarction. Muscle‐derived mitochondrial transfer via platelets is promoted by treadmill training. Platelet transfusion emerges as a potential low‐risk therapeutic strategy for sequelae and vascular dementia.

Autonomization of Microvascular Free Flaps in Reconstructive Surgery: A Narrative Review

Microsurgery, Volume 46, Issue 2, February 2026.
ABSTRACT Background Microvascular free tissue transfer is a key technique in reconstructive surgery, enabling functional and aesthetic restoration of complex defects. While initial flap survival relies on the vascular pedicle, some flaps may become independent through a process known as autonomization, where new vascular connections form between the ...
