4. Linear and Nonlinear Heart Rate Variability Analysis in Gonadal Dysgenesis (Swyer Syndrome): A Case Report
Abstract Swyer syndrome is one of the disorders of sexual differentiation. Previous studies have demonstrated increased sympathetic activity with heart rate variability (HRV) analysis with decreasing estradiol levels. One patient presented a pure 46, XY gonadal dysgenesis with female phenotype. Cardiac autonomic modulation was assessed through HRV analysis w

5. Ditching candidate gene association studies: lessons from psychiatric genetics
Objective: Longitudinal measurement invariance analyses are an important way to assess a test’s ability to estimate the underlying construct over time, ensuring that cognitive scores across visits represent a similar underlying construct, and that changes in test performance are attributable to individual change in cognitive abilities. We aimed to evaluat

6. Acute Blood Pressure Response to Different Resistance Programs in Trained Men
Abstract Background Resistance training is used in different exercise programs, with different objectives and different levels of physical fitness. Training-related variables, such as volume, rest time and intensity, can affect the response of blood pressure (BP), but studies on the effect of these variables on BP are still needed. Objective To evaluate th

7. Robotic parastomal hernia repair
ABSTRACT Introduction and Objective: Annually, more than one hundred thousand new stomas are created in the United States and near 30-50% of those will develop parastomal hernia (1). Occasionally parastomal hernias may result in life threatening complications such as bowel obstruction or strangulation requiring urgent surgical intervention (2). The minimall

10. Liquid-phase RTD studies in a flotation column: an analysis between tanks-in-series and axial dispersion models
Abstract The objective of the present study is to evaluate the fluid dynamics of a flotation column (2" in diameter and 6 m in height) based on gas hold-up measurements and, in particular, by applying the liquid-phase RTD (residence time distribution) technique. Additionally, a comparative study is performed between different methodologies used to determine
