Respiratory parameters measured by whole-body barometric plethysmography (WBBP). [PDF]

, 2015
Means (m) and standard deviations of the means (sd) of RR, Te/Ti, PEF/PIF, and MV/BW were calculated for 20 breaths collected from each dog.RR = respiratory rate (breath per minute); Te/Ti = expiratory time (s) /inspiratory time(s); PEF/PIF = peak ...

Determination of Ventilatory Volume in Mice by Whole Body Plethysmography.

The Japanese Journal of Physiology, 1997
We examined the reliability of whole-body plethysmography (WBP) for determining the ventilatory volume in mice. The degree of agreement of tidal volume (VT) determined consecutively by WBP with that by direct plethysmography (DP) or pneumotachography (PT) was analyzed using urethane-anesthetized young male 129/Sv mice.

The abdominal circulatory pump. [PDF]

PLoS ONE, 2009
Blood in the splanchnic vasculature can be transferred to the extremities. We quantified such blood shifts in normal subjects by measuring trunk volume by optoelectronic plethysmography, simultaneously with changes in body volume by whole body ...

Positive correlation of airway resistance and serum asymmetric dimethylarginine (ADMA) in bronchial asthma patients lacking evidence for systemic inflammation

Allergy, Asthma & Clinical Immunology, 2018
Background Contribution of nitric-oxide (NO) pathway to the pathogenesis of bronchial asthma (asthma) is ambiguous as NO may confer both protective and detrimental effects depending on the NO synthase (NOS) isoforms, tissue compartments and underlying ...

Whole body air displacement plethysmography compared with hydrodensitometry for body composition analysis [PDF]

Archives of Disease in Childhood, 2000
To assess the acceptability and feasibility of whole body air displacement plethysmography in children and to determine its precision and agreement with hydrodensitometry, an appropriate reference method.Age specific two component model equations were used to predict fat mass from body density in 22 children aged 8-12 years and in 10 adults for ...

An open-source tool for automated analysis of breathing behaviors in common marmosets and rodents

eLife, 2022
The respiratory system maintains homeostatic levels of oxygen (O2) and carbon dioxide (CO2) in the body through rapid and efficient regulation of breathing frequency and depth (tidal volume).

Evaluation of the Sensory Stimulation Intensity of Representative Spicy Flavor Substances Using Whole-Body Plethysmography [PDF]

Shipin Kexue
This study aimed to investigate the impact of spicy stimuli on the respiratory status of rats inhaling aerosols of spicy substances. The intensity of spicy stimuli was characterized by examining changes in multiple respiratory function indicators ...

Inhalable ROS‐Responsive Nanospray Activates PPAR‐γ to Restore Macrophage Mitochondrial Homeostasis and Attenuate Radiation‐Induced Lung Injury

Advanced Science, EarlyView.
A nebulized nanoassembly alleviates radiation‐induced lung injury by reprogramming macrophages through coordinated ROS scavenging, NAD+ replenishment, and PPAR‐γ activation. Redox balance, mitochondrial homeostasis, and immune regulation are restored, revealing a microenvironment‐centered strategy for localized radioprotection.

Evaluation of air-displacement plethysmography in children aged 5-7 years using a three-component model of body composition [PDF]

, 2003
The aim of the present study was to evaluate air-displacement plethysmography (ADP) in children aged 5-7 years. Body-composition measurements were obtained by ADP, H-2 dilution and anthropometry in twenty-eight children. Calculation of body volume by ADP
