The aim of the study was to assess the value of multiparametric ultrasound in atherosclerotic cardiovascular disease risk screening of the carotid artery. We performed ultrasonography of carotid arteries in 96 adults in 3 age groups: senior (age ≥65 years, n = 44), middle age (age 45-64 years, n = 31), and young adults (age 20-44 years, n = 21). The senior group was then divided into subgroups: athletes (n = 21) and non-athletes (n = 23). Ultrasound parameters included carotid intima-media thickness, distensibility coefficient, and presence of plaque(s). Statistical analyses included one-way a

Abstract:

SUMMARY Detecting dependence between two random variables is a fundamental problem. Although the Pearson correlation coefficient is effective for capturing linear dependence, it can be entirely powerless for detecting nonlinear and/or heteroscedastic patterns. We introduce a new measure, G-squared, to test whether two univariate random variables are independent and to measure the strength of their relationship. The G-squared statistic is almost identical to the square of the Pearson correlation coefficient, R-squared, for linear relationships with constant error variance, and has the intuitive

We aimed to determine the exercise intensity eliciting the highest (FATmax) and the lowest (FATmin) fat oxidation rate in sedentary men with obesity and to examine if these intensities correlate with their individual aerobic (AeT) and anaerobic (AnT) thresholds, respectively. Nineteen obese males performed breath-by-breath analysis to assess maximal oxygen consumption (VO2max) and to calculate their fat oxidation rate. Pearson correlation coefficient (r), coefficient of determination (R2) and paired t-test were used to evaluate VO2 at AeT and at FATmax and VO2 at AnT and at FATmin, respectivel

Abstract:

The study of plant cover have been performed by the hyperspectral remote sensing method using ASD FieldSpec® 3FR and DJI STS-VIS measurements. The orthophotoplans are compiled for the test plots of interest at the spatial resolution of 2.5 cm. The substantial correlation for the results of terrestrial verification for the satellite image data in the range of Sentinel-2A bands are confirmed. 15 vegetation indices for the Sentinel-2А wavelength bands were drawn at the Pearson correlation coefficient r > 0.97, with a maximum value of the correlation error of 0.07.

Objectives To determine whether age, body mass index (BMI), hand length and forearm circumference were predictive of hand grip strength in healthy Saudi Arabian adult males. Methods This cross-sectional descriptive study recruited healthy adult male volunteers. Their anthropometric characteristics including age, BMI, hand length and forearm circumference were measured using routine techniques. Hand grip strength was assessed using a Jamar® Hydraulic Hand Dynamometer. The data were analysed using Pearson correlation coefficient ( r) as well as by a stepwise multiple linear regression analysis.

Abstract Molecular profiling strategies generally apply either transcriptomic or proteomic technologies for dissection of aberrant expression patterns between normal and diseased samples. Although studies in yeast (S. cerevisiae) demonstrate excellent concordance between gene/protein abundance, the lack of integrated comparisons using human systems prompted us to stringently dissect these relationships in a cellular model system (platelets) devoid of active transcriptional activity. Highly-purified platelets from four healthy donors were pooled for proteomic analyses which were completed in du

The monocrotaline-induced pulmonary hypertension model is the most used animal model. In this model, invasive and non-invasive hemodynamic variables that resemble human measurements have been used. Aim: To define if non-invasive variables can predict hemodynamic measures in the monocrotaline-induced pulmonary hypertension model.
