A Comparison of Body Composition Across Two Phases of the Menstrual Cycle Utilizing Dual-Energy X-Ray Absorptiometry, Air Displacement Plethysmography, and Bioelectrical Impedance Analysis

International Journal of Exercise Science, 2017
The purpose of this investigation was to utilize several different technologies to compare body composition results across two phases of the menstrual cycle, and to investigate whether being on hormonal birth control or not has any effect on results. The

Non‐epileptic paroxysmal events in Rett syndrome: A systematic review of case‐based and observational evidence

Developmental Medicine &Child Neurology, EarlyView.
This systematic review identifies and categorizes the spectrum of non‐epileptic paroxysmal events in Rett syndrome. Respiratory disturbances, behavioural episodes, and motor events were the most commonly reported. Improving clinician awareness and diagnostic clarity is key to avoiding unnecessary treatment and enhancing quality of life for individuals ...

Low Frequency Forced Oscillation Lung Function Test Can Distinguish Dynamic Tissue Non-linearity in COPD Patients

Frontiers in Physiology, 2019
This paper introduces the use of low frequencies forced oscillation technique (FOT) in the presence of breathing signal. The hypothesis tested is to evaluate the sensitivity of FOT to various degrees of obstruction in COPD patients. The measurements were

Extracellular vesicle microRNAs are biomarkers of focal epilepsy but not epilepsy‐related respiratory dysfunction

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to evaluate the diagnostic value of a set of preselected candidate microRNAs (miRNAs) extracted from plasma‐based extracellular vesicles (EVs) to identify patients with seizure‐related respiratory dysfunction. Methods A two‐step design was applied.

Development of an Oxygen Saturation Monitoring System by Embedded Electronics [PDF]

, 2017
Measuring Oxygenation of blood (SaO2) plays a vital role in patient’s health monitoring. This is often measured by pulse oximeter, which is standard measure during anesthesia, asthma, operative and post-operative recoveries.

Respiratory dysfunction and fatal apnea during pilocarpine‐induced status epilepticus

Epilepsia, EarlyView.
Abstract Objective Status epilepticus (SE) is second only to sudden unexpected death in epilepsy as a cause of seizure‐related mortality. The progression of respiratory dysfunction during experimental SE remains poorly characterized. We investigated how pilocarpine‐induced SE affects respiration in mice.

Aortic frequency response determination via bioimpedance plethysmography

, 2019
Objective: Arterial stiffness is an important marker to predict cardio vascular events. Common measurement techniques to determine the condition of the aorta are limited to the acquisition of the arterial pulse wave at the extremities.
