In this paper is presented the research and development of a new myocardial contrast echocardiography (MCE)-based quantitative analysis system for myocardial microcirculation. The system can measure the values of A, beta, A x beta, A-EER (endo-epi ratio of A), beta-EER and A x beta-EER from the signal intensity of real-time 2-D grayscale images and power Doppler images; it can draw the time-intensity curves to indicate the variation of the intensity of microbubbles scattering in subendocardial layer and subepicardial layer with the varying of myocardial segments; and it can estimate the hemodynamic parameters by nonlinear regression analysis. So the MCE software system has brought the quantitative analysis of real-time MCE to success.

Fraud in alcoholic beverages through counterfeiting and adulteration is rising, significantly impacting companies economically. This study aimed to develop a method using near-infrared (NIR) spectroscopy (1596-2396 nm) through the bottle, along with machine learning (ML) modeling for beer authentication, quality traits, and control assessment. For this study, 25 commercial beers from different brands, styles, and three types of fermentation were used.

The anionic species of antimony(V) and phosphate(V) are commonly found in the contaminated soil of mining areas, exerting a significant influence on the sorption of heavy metals and thus affecting their migration. This study quantitatively discussed the sorption mechanism of Sb and P in promoting the sorption of Cd or Cu on goethite through a series of extraction methods. In the single sorption system, the majority of Cu (87-98%) is adsorbed on goethite in the form of EDTA-extractable Cu (EF Cu, possibly inner-sphere complexes) under pH conditions of 3.

Background: Telehomecare monitoring (TM) in patients with cancer is a complex intervention. Research shows variations in the benefits and challenges TM brings to equitable access to care, the therapeutic relationship, self-management, and practice transformation. Further investigation into these variations factors will improve implementation processes and produce effective outcomes.

The aim of this research is to analyze the attitude of future teachers toward death education and which are the factors that influence their predisposition about it. For this, a quantitative study with a descriptive-inferential cross-sectional design was carried out with a sample composed of 204 Primary Education Degree students from the University of Malaga. The Death Education Attitudes Scale-Teachers was implemented as a validated instrument, in which biological, emotional, identity, contextual, formative and motivational factors were considered within the attitude's incidence.

Purpose: The dentato-rubro-thalamo-cortical tract (DRTC) is considered to play a crucial role across tremor disorders including tremor dominant Parkinson's disease (TDPD) and essential tremor plus (ETP). This study aims to comprehensively evaluate microstructural integrity of the DRTC using single-compartment, i.e.
