Drew Weatherhead, Katherine S White
What do infants hear when they read lips? In the present study, twelve-to-thirteen-month-old infants viewed a talking face produce familiar and unfamiliar words. The familiar words were of three types: in Experiment 1, they were produced correctly (e.g., "bottle"); in Experiment 2, infants saw and heard mispronunciations in which the altered phoneme either visually resembled the original phoneme (visually consistent, e.g. "pottle"), or did not visually resemble the original phoneme (visually inconsistent, e...

INTRODUCTION: Cardiovascular disease (CVD) caused significant burden to Malaysia as it accounted for 36% of total deaths. This study aims to evaluate the burden of cardiovascular risk factors among Malaysian adult and assess the difference between urban and rural population in the selected communities. METHODS: This study is part of the ongoing Prospective Urban Rural Epidemiology (PURE) database, whereby the baseline data were collected since June 2008. CVD risk was measured using INTERHEART risk score which comprised of eleven risk factors i...

Objective: To investigate the changes of aortic stiffness and its influencing factors in patients with chronic kidney diseases (CKD). Methods: Eightyfour patients with CKD from Department of Nephrology, Zhejiang Provincial People's Hospital were divided into the dialysis group (CKD stage 5, n=48) and non-dialysis group (CKD stage 3-5, n=36). Clinical data, biochemical parameters and echocardiography findings were collected. SphygmoCor pulse wave analysis system was used to obtain pulse wave analysis (PWA) parameters including central aortic systolic blood pressure (CSP), central pulse pressure (CPP), augmented pressure (AP), augmentation index (AIX), and heart rate 75-adjusted augmentation index (HR75AIX)...

OBJECTIVES: To provide contemporary Australian data on the public's training in cardiopulmonary resuscitation (CPR) and awareness of hands-only CPR. METHODS: A cross-sectional telephone survey in April 2016 of adult residents of the Australian state of Victoria was conducted. Primary outcomes were rates of CPR training and awareness of hands-only CPR. RESULTS: Of the 404 adults surveyed (mean age 55 ± 17 years, 59% female, 73% metropolitan residents), 274 (68%) had undergone CPR training...

The pentamidine analog PA-6 was developed as a specific inward rectifier potassium current (IK1) antagonist, because established inhibitors either lack specificity or have side effects that prohibit their use in vivo. We previously demonstrated that BaCl2, an established IK1 inhibitor, could prolong action potential duration (APD) and increase cardiac conduction velocity (CV). However, few studies have addressed whether targeted IK1 inhibition similarly affects ventricular electrophysiology. The aim of this study was to determine the effects of PA-6 on cardiac repolarization and conduction in Langendorff-perfused guinea pig hearts...

BACKGROUND: Treatments that reduce mortality and morbidity in patients with heart failure with reduced ejection fraction, including angiotensin-converting enzyme inhibitors (ACEI), angiotensin receptor blockers (ARB), β-blockers (BB), mineralocorticoid receptor antagonists (MRA), and angiotensin receptor-neprilysin inhibitors (ARNI), have not been studied in a head-to-head fashion. This network meta-analysis aimed to compare the efficacy of these drugs and their combinations regarding all-cause mortality in patients with heart failure with reduced ejection fraction...

BACKGROUND: Heart failure with reduced ejection fraction caused by ischemic heart disease is associated with increased morbidity and mortality. It remains unclear whether revascularization by either coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) carries benefits or risks in this group of stable patients compared with medical treatment. METHODS AND RESULTS: We performed a meta-analysis of available studies comparing different methods of revascularization (PCI or CABG) against each other or medical treatment in patients with coronary artery disease and left ventricular ejection fraction ≤40%...

For heart regeneration, the proliferative potential of cardiomyocytes in postnatal mice is under intense investigations. However, solely relying on immunostaining of proliferation markers, the long term proliferation dynamics and potential of the cardiomyocytes cannot be readily addressed. Previously, we found that a p53 promoter driving reporter predominantly marked the proliferating lineages in mice. Here, we established a p53 based genetic tracing system to investigate postnatal cardiomyocyte proliferation and heart regeneration...

Heart transplantation results in complete denervation of the donor heart with loss of afferent and efferent nerve connections. The majority of patients remain completely denervated during the first 6-12 months following transplantation. Evidence of reinnervation is usually found during the second year after transplantation and involve the myocardial muscle, sinoatrial node, and coronary vessels, but remains incomplete and regionally limited many years post-transplant. Restoration of cardiac innervation can improve exercise capacity as well as blood flow regulation in the coronary arteries, and hence improve quality of life...

AIMS: The adult human sinoatrial node (SAN) has a specialized fibrotic intramural structure (35-55% fibrotic tissue) that provides mechanical and electrical protection from the surrounding atria. We hypothesize that late gadolinium-enhanced cardiovascular magnetic resonance (LGE-CMR) can be applied to define the fibrotic human SAN structure in vivo. METHODS AND RESULTS: LGE-CMR atrial scans of healthy volunteers (n olu, 23-52 y.o.) using a 3 Tesla magnetic resonance imaging system with a spatial resolution of 1...

AIMS: Atrial fibrillation (AF) is the leading rhythm disorder in western countries. A direct relationship between left atrium (LA) enlargement and electromechanical remodelling has been established. A causative link between epicardial fat (EF), visceral adipose tissue deposited around the heart, and AF has been hypothesized. Several reports suggested the association between EF and the presence of AF. The aim of this study was to verify the relationship between AF and EF depot, performing a meta-analysis of observational case series studies...

INTRODUCTION: Atrial fibrillation (AF) is a cause of stroke and a marker of atherosclerosis and of all patients with stroke, around 17% have AF. The screening and treatment of AF could prevent about 12% of all strokes. Several relatively low-cost devices with good accuracy now exist which can detect AF including WatchBP and AliveCor. However, they can only measure the ECG or pulse over short time periods. Inexpensive devices such as heart rate monitors, which are widely available, can measure heart rate for prolonged periods and may have potential in screening for AF...

: Background The influence of cardiac sympathetic innervation on electrical activation in normal and chronically infarcted ventricular myocardium is not understood. Methods and Results Yorkshire pigs with normal hearts (NL, n=12) or anterior myocardial infarction (MI, n=9) underwent high-resolution mapping of the anteroapical left ventricle, at baseline, and during left and right stellate ganglion stimulation (LSGS & RSGS, respectively). Conduction velocity (CV), activation times (AT), & directionality of propagation were measured...

: To promote drug accumulation and cell-killing ability at tumor tissue, we have prepared a stepwise targeted drug delivery system that can remain stealthy and long-circulating in the blood vessels, improve drug retention at extracellular stimuli, enhance cellular uptake through special targeting ligands, and then achieve rapid drug release to improve toxicity to tumor cells at intracellular stimuli. Herein, galactose-grafted, ultra-pH-sensitive drug carriers (POEAd-g-LA-DOX micelles), which could respond to both extracellular and intracellular pH, and combine with galactose-receptors in cell membrane, were constructed by a facile method, therefore achieving: (i) remaining stable at pH 7...

: Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) provide an unlimited cell source to treat cardiovascular diseases, the leading cause of death worldwide. However, current hiPSC-CMs retain an immature phenotype that leads to difficulties for integration with adult myocardium after transplantation. To address this, we recently utilized electrically conductive silicon nanowires (e-SiNWs) to facilitate self-assembly of hiPSC-CMs to form nanowired hiPSC cardiac spheroids...
