High‐Resolution Imaging of Extracellular pH in Mouse Liver Tumor

NMR in Biomedicine, Volume 39, Issue 9, September 2026.
High‐resolution imaging of extracellular pH (pHe) using 1H‐BIRDS with REduced Spherical Encoding with GAussian Weighting (RESEGAW) was achieved in an orthotopic mouse liver tumor (Hepa1–6) model and was validated with 31P MRSI using 3‐aminopropylphosphonate, showing excellent agreement between the two methods.

Oxygenaging: A Physiological Framework for Geroscience

Aging Cell, Volume 25, Issue 9, September 2026.
Mechanisms of aging disrupt oxygen homeostasis through three converging processes: oxygen‐cascade impairment, microvascular dysfunction, and molecular maladaptation. “Oxygenaging” integrates these domains to explain how declining oxygen delivery and utilization drive mitochondrial instability and amplify the effect of the hallmarks of aging.

Aged Mitochondrial DNA Is Associated With Aberrant Acute Exercise‐Induced Redox Responses in Human Skeletal Muscle

Aging Cell, Volume 25, Issue 9, September 2026.
Findings from this study suggest that aging is accompanied by altered skeletal muscle mitochondrial redox regulation and exercise responsiveness, with decreased mtDNA copy number, increased mtDNA mutation deletion frequency, and selective redox remodeling of key mitochondrial proteins representing potential contributors to these changes. ABSTRACT Redox

Aging Alters Hair Cell Physiological Properties in Mice With Late‐Onset Age‐Related Hearing Loss

Aging Cell, Volume 25, Issue 9, September 2026.
Hidden hearing loss during aging is associated with peripheral auditory system decline. We discovered that aging sensory hair cells decrease in size. In addition, inner hair cells exhibit a reduced K+ current carried out by BK channels, accompanied by an elevated resting membrane potential, suggesting an age‐related functional impairment.

Recent advances in phosphocreatine metabolism and its role in cancer research

Zhongguo aizheng zazhi
Phosphocreatine (PCr), traditionally recognized as an intracellular high-energy phosphate compound, mainly functions as a rapid energy buffer through the creatine kinase system to meet the high-energy demands of cells.
