As an important structural analogue of bisphenol A (BPA), bisphenol S (BPS) has been used as alternatives to BPA in industrialized production. However, the immunotoxicity of BPS remains poorly understood. As a critical model in inflammatory responses, macrophages are used to explore the immunotoxic potential and mechanisms of BPS at environmentally relevant concentrations in our study. Here, we are combining molecular toxicology and mass spectrometry (MS)-based global metabolomics and lipidomics study together to estimate the variation of cytokines profiling and metabolism characteristic following BPS exposure...

Cardiac allograft rejection (CAR) may occur after transplantation and remains silent, until hemodynamic deterioration takes place. Endomyocardial biopsy (EMB) is applied to early detect CAR. Although, flexible bioptoms have decreased the incidence of lethal complications, EMB remains an invasive procedure carrying risk of tamponade and permanent heart block. Therefore, a new non-invasive approach is needed. Areas covered: AlloMap molecular expression testing and graft-derived cell-free DNA (GcfDNA) test can be used as blood indices of acute and chronic CAR, respectively...

To evaluate the right ventricular (RV) function in relation to that of the left ventricle (LV) in patients with dilated cardiomyopathy (DCM). Echocardiographic examination was done using tissue Doppler imaging (TDI) and two-dimensional speckle tracking echocardiography (2D-STE) for 32 pediatric patients with DCM comparing them to another 32 normal matched controls. The global longitudinal strain (GLS) derived from 2D-STE was used to reflect the LV systolic function. Tricuspid annular plan systolic excursion (TAPSE) and the following RV TDI derived indexes: peak systolic velocity (S'), peak early diastolic velocity E', peak late diastolic velocity A', isovolumic acceleration (IVA) and myocardial performance index (MPI) were measured...

BACKGROUND AND AIM: NO synthase 2 (NOS2) was recently identified as one the most overexpressed genes in intestinal samples of premature infants with necrotizing enterocolitis (NEC). NOS2 is widely implicated in the processes of epithelial cell injury/apoptosis and host immune defense but its specific role in inflammation of the immature human intestinal mucosa remains unclear. Interestingly, factors that prevent NEC such as epidermal growth factor (EGF) attenuate the inflammatory response in the mid-gestation human small intestine using serum-free organ culture while drugs that are associated with NEC occurrence such as the non-steroidal anti-inflammatory drug, indomethacin (INDO), exert multiple detrimental effects on the immature human intestine...

BACKGROUND: High sensitive troponin T (hsTnT), a marker of myocardial injury, appears to be a promising diagnostic tool in patients with congenital heart disease. However, little is known about its distribution among adults with systemic right ventricle (sRV). We aimed to assess the distribution of hsTnT concentrations in patients with congenitally corrected transposition of the great arteries (ccTGA) and to evaluate its relationship with sRV function and NT-proBNP. METHODS: A cross-sectional study of adults with ccTGA was conducted...

Three-dimensional (3D) speckle tracking echocardiography (STE) is a reliable clinical tool for accurate measurements of left ventricular (LV) volumes and ejection fraction (EF). In this prospective study, we sought to identify an association between 3DSTE longitudinal strain abnormalities and areas of late gadolinium enhancement (LGE). In 50 patients (52 ± 18.5 years old) referred to our hospital for clinically indicated CMR, 3D full-volume trans-thoracic acquisitions on apical views were performed within 1 h of CMR, in order to obtain LV volumes and ejection fraction as well as global and segmental peak systolic longitudinal strain...

Evaluation of myocardial mechanics after heart transplant is important in monitoring allograft function and identifying rejection. Speckle tracking global longitudinal strain (GLS) may be more sensitive to early regional changes from rejection. This study aimed to determine feasibility of GLS in pediatric hearts during surveillance echocardiograms, compare their GLS to published norms (-18% to -22%), and assess association of GLS with other indices of graft function. Retrospective review of transplant echocardiograms from 2013 to 2014...

BACKGROUND: Cardiac allografts are routinely evaluated by left ventricular ejection fraction (LVEF) before and after transplantation. However, myocardial deformation analyses with LV global longitudinal strain (GLS) are more sensitive for detecting impaired LV myocardial systolic performance compared with LVEF. METHODS: We analyzed echocardiograms in 34 heart donor-recipient pairs transplanted at Duke University from 2000-2013. Assessments of allograft LV systolic function by LVEF and/or LV GLS were performed on echocardiograms obtained pre-explanation in donors and serially in corresponding recipients...

BACKGROUND: Left ventricular ejection fraction (LVEF) is a predictor of adverse outcomes in hemodialysis patients. LVEF is, however, an integral parameter determined by contractility, loading condition, and coupling. We sought to determine whether these components would better predict adverse outcomes and have incremental prognostic value over a validated clinical score and EF. METHODS: Two hundred thirty-four hemodialysis patients were prospectively followed up for primary composite endpoint: all-cause death, nonfatal myocardial infarction, and hospitalization due to worsening heart failure (HF)...
