Evaluation of the Volatile Sulfur Compound Stability in Breath Samples for Halitosis Remote Diagnosis

Oral Diseases, EarlyView.
ABSTRACT Background This study assessed the feasibility of remote halitosis diagnosis by evaluating VSC stability over 7 days and their association with periodontal parameters. Methods One hundred adult patients attending a periodontal examination were included.

Advances in Breath Analysis-Based Disease Diagnosis Technology and Standardization Requirements

Zhipu Xuebao
The composition and content of volatile organic compounds (VOCs) in exhaled breath are closely related to change in the human physiological state. Some biosignature molecules generated by human metabolism, including disease marker molecules, are expelled

An integrated behavioral change model for smoking cessation in periodontal care: The four‐stage behavioral support staircase

Periodontology 2000, EarlyView.
Abstract Objectives Smoking tobacco is a critical modifiable risk factor for periodontal and peri‐implant diseases. This narrative review integrates established behavioral theories with communication‐based psychological processes to propose an evidence‐based model for smoking cessation support in periodontal care.

Self-powered triboelectric nanogenerator sensor for detecting humidity level and monitoring ethanol variation in a simulated exhalation environment

Scientific Reports
Respiration stands as a vital process reflecting physiological and pathological human health status. Exhaled breath analysis offers a facile, non-invasive, swift, and cost-effective approach for diagnosing and monitoring diseases by detecting ...

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Sex differences in the prefrontal cortex and muscle oxygenation during exercise until exhaustion in endurance‐trained individuals

Experimental Physiology, EarlyView.
Abstract figure legend During cardiopulmonary exercise testing, the decline in oxygenation in the prefrontal cortex of women is striking. This crucial brain area is directly involved in planning motor tasks. The decline is particularly pronounced at higher exercise intensities, especially after reaching the respiratory compensation point or anaerobic ...

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

Experimental Physiology, EarlyView.
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 ...

Splenic contraction associated with sudden, transient hypotension and sympathoexcitation in humans

Experimental Physiology, EarlyView.
Abstract The spleen is traditionally recognised for its roles in immunity and blood filtration, and it is known to contract and release stored erythrocytes in hypoxic conditions. Recent findings suggest that the spleen may also contribute to cardiovascular regulation.

Daily hot‐water immersion preserves altitude‐induced haemoglobin mass expansion following descent independent of erythropoietin

Experimental Physiology, EarlyView.
Abstract High‐altitude exposure increases haemoglobin mass (Hbmass), a key determinant of arterial oxygen‐carrying capacity, but following descent this adaptation can regress toward baseline within 7 days. Long‐term heat acclimation has emerged as an alternative stimulus for Hbmass expansion; however, whether post‐altitude passive‐heat exposure can ...

Effects of nocturnal periodic breathing on sympathetic nerve activity and ventilatory control at high altitude: a randomised, crossover study

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the randomised crossover study investigating the effects of nocturnal periodic breathing (nPB) on sympathetic activity and ventilatory acclimatisation in hypobaric hypoxia equivalent to 4000 m altitude. Participants completed two 3‐day sojourns where nPB was inhibited by increasing inspiratory CO2 fraction ...
