Acute intermittent hypercapnic hypoxia augments left ventricular contractility

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...

The role of group III/IV afferent feedback in the ventilatory, pressor and metabolic responses to exercise in normoxia and hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Participants completed cycling exercise with (placebo) and without (25 µg intrathecal fentanyl) intact group III/IV muscle afferent feedback in three settings: normoxia, acute hypoxia and chronic hypoxia after 7–9 days of acclimatisation (∼3800 m). Blocking afferent feedback suppressed exercise hyperpnoea across all environments,

Peroxynitrite‐induced structural remodeling and aggregation of hemoglobin under nitroxidative stress

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract Peroxynitrite (PN), generated by the reaction of nitric oxide with superoxide, is a potent reactive nitrogen species (RNS) implicated in nitroxidative protein damage in cardiovascular and neurodegenerative diseases. Hemoglobin (Hb), the principal oxygen‐transport protein of erythrocytes, is a key intravascular scavenger and target of PN ...

You Are Always on My Mind: Neural Synchrony Between Mothers and Their 2‐Year‐Olds During Collaborative Play

open access: yesDevelopmental Science, Volume 29, Issue 5, September 2026.
ABSTRACT Working with others is an essential skill for everyday life. Interpersonal neural synchrony (INS) has been suggested as a potential neurobiological correlate of collaboration between parents and school‐aged children. This study investigated whether interpersonal neural synchrony (measured using Wavelet Transform Coherence) is also a correlate ...

Donor Screening and Stoichiometry Engineering‐Driven Supramolecular Charge‐Transfer Complexes for Synergistic Tumor Near‐Infrared‐II Phototherapy

open access: yesAggregate, Volume 7, Issue 8, August 2026.
This work presents 2A‐D2, a supramolecular charge‐transfer complex via donor screening and stoichiometry modulation for near‐infrared‐II phototherapy. Optimizing the assembly ratio induces loose molecular packing, mitigating reactive oxygen species quenching while maintaining high photothermal effects. This synergistic photothermal therapy/photodynamic

Evaluating Sleep Apnea: In‐Lab Versus at‐Home Recording Time and the Impact of Positional Disease

open access: yesThe Laryngoscope, Volume 136, Issue 8, Page 3639-3647, August 2026.
We evaluated the minimum recording time needed for in‐lab polysomnography (PSG1) and home sleep apnea test Type 3 portable monitoring (HSAT) to accurately reflect the full‐night apnea–hypopnea index (AHI) in patients with suspected obstructive sleep apnea (OSA).

Differentiating solar lentigines from post‐inflammatory hyperpigmentation with hyperspectral imaging: A pilot study

open access: yesInternational Journal of Cosmetic Science, Volume 48, Issue 4, Page 738-746, August 2026.
This preliminary study attempted to characterize solar lentigines and post‐inflammatory hyperpigmentation (PIH) observed on Japanese women. Colorimetric features and chromophore concentrations were measured using hyperspectral imaging for each hyperpigmentation type.

Reference Values for Pulse Oximetry Testing in Permanent Teeth: A Systematic Review and Meta‐Analysis

open access: yesInternational Endodontic Journal, Volume 59, Issue 8, Page 1557-1585, August 2026.
ABSTRACT Background Pulse oximetry is an accurate diagnostic method for assessing the condition of the dental pulp; however, the normal oxygen saturation levels for each tooth type are yet to be clearly defined. Objectives This systematic review and meta‐analysis aims to answer the question: What are the reference values for pulse oximetry testing in ...

Interindividual variability in static apnoea performance is partly explained by genetic factors

open access: yesExperimental Physiology, Volume 111, Issue 8, Page 3718-3730, 1 August 2026.
Abstract A large interindividual variability exists in maximal apnoea duration and the physiological adjustments that occur during apnoea. Although a few genes have been found to be associated with some of the cardiovascular responses during apnoea, the extent to which genetic and environmental factors contribute to individual differences in apnoea ...

Integrating mechanical, physiological, and muscle oxygenation responses during field‐based tethered repeated‐sprint exercise in male professional soccer players

open access: yesPhysiological Reports, Volume 14, Issue 15, August 2026.
Abstract Repeated‐sprint ability is a key determinant of soccer performance. However, some mechanical and physiological responses underlying this task remain incompletely understood. This study characterized mechanical responses (force, velocity, and power) and regional muscle oxygen saturation (rSmO2) in the vastus lateralis (VL) and biceps brachii ...
