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

open access: yesInternational 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

Exact Green's functions and Bosonization of a Luttinger liquid coupled to impedances [PDF]

open access: yes, 2007
The exact Green's functions of a finite-size Luttinger Liquid (LL) connected to impedances are computed at zero and finite temperature. Bosonization for a LL with Impedance boundary conditions (IBC) is proven to hold. The LL with open boundary conditions (for both Neumann and Dirichlet cases) is explicitly recovered as a special limit when one has ...

Validity of non‐traditional measures of obesity compared to total body fat across the life course: A systematic review and meta‐analysis

open access: yesObesity Reviews, Volume 26, Issue 6, June 2025.
Summary IntroductionTraditional obesity measures including body mass index, waist circumference, waist‐to‐hip ratio, and waist‐to‐height ratio have limitations. The primary objective of this study was to identify and review the validity of non‐traditional obesity measures, using measures of total body fat as the reference standard, that have been used ...

How do glucagon‐like Peptide‐1 receptor agonists affect measures of muscle mass in individuals with, and without, type 2 diabetes: A systematic review and meta‐analysis

open access: yesObesity Reviews, EarlyView.
Summary Glucagon‐like peptide‐1 receptor agonists (GLP1RAs) are used for the management of type 2 diabetes (T2DM) and obesity. GLP1RAs induce significant weight loss but concerns have been raised regarding the associated effects on muscle mass (MM). We therefore conducted a systematic review and meta‐analysis assessing the effects of GLP1RAs on various

Fixed CPAP at 10 cmH2O May Replace Manual Titration in Moderate to Severe OSA Patients: A Preliminary Randomised Controlled Trial

open access: yesRespirology, EarlyView.
ABSTRACT Background and Objectives Patient compliance with continuous positive airway pressure (CPAP) is similar using manual‐titrated pressure compared to auto‐titration, although auto‐titration pressures are usually 2–5 cmH2O higher than manual pressure, indicating that CPAP moderately higher than the optimal pressure will not necessarily impair ...

Impact of artificial airway resistances on regional ventilation distribution during airway closure

open access: yesCurrent Directions in Biomedical Engineering, 2020
Electrical impedance tomography (EIT), a noninvasive and radiation-free imaging technique can be used in pulmonary function monitoring for determining regional ventilation distribution within the lung.

Correlation of Air Displacement Plethysmography with Alternative Body Fat Measurement Techniques in Men and Women [PDF]

open access: yes, 2012
International Journal of Exercise Science 5(4) : 367-378, 2012. Obesity has reached epidemic proportions with serious health consequences. Techniques used to measure body fat (BF) yield variable BF estimates, and this variability may lead to ...

Stochastic Impedance [PDF]

open access: yes, 2019
The concept of impedance, which characterises the current response to a periodical driving, is introduced in the context of stochastic transport. In particular, we calculate the impedance for an exactly solvable model, namely the stochastic transport of particles through a single-level quantum dot.

Resistance exercise breaks during prolonged sitting augment the blood flow response to a subsequent oral glucose load in sedentary adults

open access: yesExperimental Physiology, EarlyView.
Abstract Sitting‐induced impairments in postprandial blood flow are an important link between sedentary behaviour and cardiometabolic disease risk. The objective of this work was to examine the effects of resistance exercise breaks (REB) performed every 30 min during an otherwise sedentary 3‐h period on the vasodilatory response to a subsequent oral ...
