Purpose: To propose using the generalized least square (GLS) algorithm for combining multichannel single-voxel magnetic resonance spectroscopy (MRS) signals.
Materials And Methods: Phantom and in vivo brain MRS experiments on a 7 T scanner equipped with a 32-channel receiver coil, as well as Monte Carlo simulations, were performed to compare the coefficient of variation (CV) of the GLS method with those of two recently reported spectral combination methods.
Results: Compared to the two existing methods, the GLS method significantly reduced CV values for the simulation, phantom, and in vivo experiments.
Conclusion: The GLS method can lead to improved precision of peak quantification.

Objective: ADHD is one of the most common neurodevelopmental disorders, seen in children and adolescents, and is often treated with various pharmacological agents, especially methylphenidate. There are differing opinions in the literature regarding the cardiovascular safety of long-term methylphenidate use. Studies suggest that the drug may increase the risk of hypertension, myocardial infarction, ventricular arrhythmia, sudden cardiac death, cardiomyopathy, heart failure (HF), pulmonary hypertension, and stroke.

Aim: To investigate the relationship between epicardial adipose tissue (EAT) and myocardial strain and the severity of coronary artery disease (CAD), and to evaluate the predictive value of EAT parameters in early left ventricular (LV) diastolic dysfunction.
Materials And Methods: One hundred seventy patients with suspected CAD who underwent both coronary computed tomography angiography and echocardiography were enrolled in 2020. LV global strains were calculated using commercial software.

This study aims to evaluate the impact of factors representing the Board of Directors (BOD) and Audit Committee (AC) on financial information transparency (FIT) in a frontier market. FIT is measured through three indicators that reflect financial non-transparency: earnings aggressiveness (EA), earnings smoothing (ES) and loss avoidance (LA). Research data was collected from 338 companies listed on the Vietnam Stock Exchange (HOSE and HNX) from 2012 to 2022.

Background: Adipose tissue distribution plays a crucial role in the development of cardiovascular complications. In particular, visceral adipose tissue (VAT) has been linked to insulin resistance (IR) and cardiovascular disease (CVD). However, the relationship between VAT, cardiac dysfunction and the meditation capacity of VAT related to IR has not been fully characterized.

Background: Systemic light chain amyloidosis is a rare and debilitating disease, especially for which initially presented with digestive tract involvement. Myocardial amyloidosis is highly aggressive with generally poor prognosis and often resulted in missed diagnosis or misdiagnosis with routine examination tools. Multimodality imaging play an important role in diagnosing the amyloidosis effect on multiple organs.
