Respiratory function: A systems approach
… affecting V˙A, and the medullary pontine respiratory center (MPRC) in the brain stem. The MPRC is responsible for generating the basic rhythm of breathing and corrects for disturbances. Neurons inside the MPRC are organized into a central pattern generator (CPG), the functionality of which …

A three dimensional surface measurement and reconstruction system for respiratory function analysis
… understood, an accurate dynamic model of the respiratory system could be developed and the interaction between different inputs and outputs could be investigated in a straightforward fashion. Unfortunately, this is not the case and does not appear to be viable at this time. In addition, the …

Aspects of respiratory function during exercise in the thoroughbred horse in health and disease
The horse's enormous respiratory reserve enables it to increase the respiratory load on the lungs many fold during exercise, hence low-grade respiratory disease is difficult to detect at rest, although of vital importance during heavy exercise. Diagnostic exercise testing is, therefore, of great …

Assessing the Role of Inspiratory Muscle Training in Enhancing Respiratory Function among Adults with COPD
… Pulmonary Disease (COPD) is a progressive respiratory condition characterised by persistent airflow limitation, dyspnoea and reduced functional capacity. Inspiratory muscle dysfunction, particularly weakness of the diaphragm, plays a significant role in symptom burden and reduced quality of …

The relationship between markers of disease severity in obstructive sleep apnea patients and hemodynamic and respiratory function during graded exercise testing
… testing may reveal abnormalities in hemodynamic function in obstructive sleep apnea (OSA) patients, particularly with respect to cardiac output (Qc), mean arterial pressure (MAP), and TPR that may be related to polysomnography (PSG) markers of OSA severity. Cardiorespiratory and hemodynamic …

EFFECTS OF DAPAGLIFLOZIN ON EXERCISE CAPACITY, RESPIRATORY FUNCTION, BIOMARKERS, SLEEP APNEA, AND LEFT VENTRICULAR REMODELING IN PATIENTS WITH HEART FAILURE: A PROSPECTIVE, SINGLE CENTER, NON RANDOMIZED STUDY
… spanning metabolic, cardiovascular, and renal functions. Methods: A single prospective cohort of stable HFrEF patients was studied in two parallel, complementary investigations. The first focused on exercise capacity, cardiac remodelling, fluid status, and conventional biomarkers. The second …

The effects of gene replacement therapy on respiratory and gait function in a canine model of X-linked myotubular myopathy
… ventilator and wheelchair dependent, with respiratory failure as the leading cause of death. A potential gene therapy has been developed where AAV8 mediates MTM1 replacement. A naturally-occuring canine model of the disease displays a phenotype similar to that seen in patients, including …

Work of breathing in exercise and disease
… on developing new methods and outcomes to assess respiratory function that require little or no volitional effort on behalf of the participants being tested. Specifically to attempt to detach the behaviour of the patient from the accuracy of the test of respiratory function, resulting in …

AGE AND SPEECH BREATHING (KINEMATICS, PHYSIOLOGY, RESPIRATORY).
… speech breathing, selected measures of general respiratory function were obtained. These included measures of subdivisions of the lung volume and measures of resting tidal breathing. Results indicated that these 30 subjects were representative of other subjects studied with respect to measures …

Lipid metabolism and mitochondrial respiration in adipose tissue and liver during obesity
… during obesity, and shows impaired energetic function. In addition, the liver is a key site of ectopic fat deposition in obesity, resulting in changes in metabolic function. It has been proposed that changes in mitochondrial respiratory function are associated with WAT expansion and hepatic …

Characterization of the dynamic behavior of lung surfactant and its components
Lung surfactant is essential to respiratory function. Surfactant dysfunction in adult respiratory distress syndrome (ARDS) is associated with an increase in the minimum surface tension achieved on compression which can result in alveolar collapse and decreased lung compliance. Knowledge of the …

Characterization of molecular and functional changes regulating hypobaric hypoxia-induced right ventricular hypertrophy
… elicited direct effects on mitochondrial respiratory function and cardiac contractility. The data show that Wy-14,643 treatment attenuated mitochondrial respiration (state 3 respiration and rate of ADP phosphorylation) in the RV while promoting uncoupling of mitochondrial oxidative …

LUNG CLEARANCE INDEX: a new biomarker of ventilation inhomogeneity in pediatric respiratory diseases.
… has long been considered the primary test of respiratory function deficit in children and adults. However, performing forced breathing manoeuvres is challenging in an uncooperative child. Furthermore, recent evidence suggests that conventional spirometry is not sensitive for the early …

Mitochondrial function in sepsis - Temporal evolvement of respiratory capacity in human blood cells
… An impaired immunologic response, including dysfunctional peripheral blood immune cells has been described as part of the septic syndrome. Mitochondrial dysfunction has been suggested to be a contributing factor in the pathogenesis of these alterations and restoration of mitochondrial function …

NEUROACTIVE AGENTS-MEDIATED CHANGES IN NEURONAL NETWORK ACTIVITY CONTROLS SUSCEPTIBILITY TO SUDDEN UNEXPECTED DEATH IN EPILEPSY (SUDEP)
… In the majority of observed human SUDEP cases, respiratory dysfunction post-seizure is shown to be the primary initiating event leading to cardiac asystole and death. During seizures, several neuroactive agents are shown to be released, including serotonin and adenosine. Previous research has …
