SARS‐CoV‐2 targets mitochondria, exacerbating COVID‐19 pneumonia

The Journal of Physiology, EarlyView.
Abstract figure legend Following entry into airway epithelial cells (AECs), SARS‐CoV‐2 releases its single‐stranded RNA into the cytoplasm, where it is translated into viral proteins. Several of these viral proteins localize to mitochondria and interact with key mitochondrial components.

Ventilatory efficiency: Physiological modelling and mechanistic validation

The Journal of Physiology, EarlyView.
Abstract figure legend From post‐threshold ventilatory linearization to ceiling‐normalized efficiency – conceptual framework underlying ηV̇E$\eta {{\dot{V}}_{\mathrm{E}}}$ Conventional V̇E${{\dot{V}}_{\mathrm{E}}}$–V̇CO2${{\dot{V}}_{{\mathrm{C}}{{{\mathrm{O}}}_2}}}$ slopes are typically derived under submaximal conditions and may become physiologically

Ventilatory and heart rate responses to hypoxia in pre‐ and post‐menopausal ethnically Tibetan women residing at ∼3800 m in Mustang, Nepal

The Journal of Physiology, EarlyView.
Abstract figure legend Tibetan women livingat high altitude exhibit distinct physiological traits that can enhance oxygen transport in chronic hypoxia. Menopausal status influences cardiopulmonary responses to hypoxia in women living at low altitudes.

Quantitative Imaging of Pyruvate Metabolism in a Patient With Anaplastic Thyroid Cancer

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 826-838, August 2026.
ABSTRACT Purpose Magnetic resonance imaging using hyperpolarized (HP) [1‐13C]‐pyruvate enables assessment of pyruvate metabolism in vivo and offers new insight into metabolic changes in response to cancer therapy. Widely used semi‐quantitative metrics of pyruvate metabolism can be affected by physiological factors that are extrinsic to intracellular ...
