Introduction: An ultra high-frequency (70 MHz) ultrasound device has recently been approved for human use. This study was conducted to determine if this device facilitates counting of fascicles within the median nerve at the wrist. Methods: Twenty healthy …

Off the shelf scaffolds for replacing ultra-small diameter vascular grafts are valuable for reconstruction of diseased or damaged vessels. The limitations for such grafts include optimal handling with ready availability of varied lengths of grafts, graft …

Metformin, a small molecule antihyperglycaemic agent, is well-known as an AMP-activated protein kinase (AMPK) activator and protects against cardiac fibrosis. However, the underlying mechanisms remain elusive. Transforming growth factor-β1 (TGFβ1) is a …

BACKGROUND Hyaluronan (HA) is required for endothelial-to-mesenchymal transition and normal heart development in the mouse. Heart abnormalities in hyaluronidase 2 (HYAL2)-deficient (Hyal2(-)(/-) ) mice and humans suggested removal of HA is also important …

Objectives—The goal of this study is to investigate the role of sex and age of the negative chronotropic effect after exposure of 3.5-MHz pulsed ultrasound (US) to the rat heart. Methods—Forty F344 rats were exposed transthoracically to ultrasonic pulses …

Background-—Sex-related differences in cardiac function and iron metabolism exist in humans and experimental animals. Male patients and preclinical animal models are more susceptible to cardiomyopathies and heart failure. However, whether similar …

Gold nanoparticles hold great promise as anti-cancer theranostic agents against cancer by actively tar- geting the tumor cells. As this potential has been supported numerously during in vitro experiments; the effective application is hampered by our …

Adipocytes play important roles in regulating cardiovascular health and disease. However, the molecular mechanism underlying the endocrine role of brown adipose tissue (BAT) in pathological cardiac remodeling remains unknown. Herein we show that adenosine …

Augmented inositol 1,4,5-trisphosphate (IP3) receptor (IP3R2) function has been linked to a variety of cardiac pathologies including cardiac arrhythmias. The functional role of IP3- induced Ca2+ release (IP3ICR) within ventricular excitation-contraction …

High frequency micro-ultrasound (µUS) transducers with central frequencies up to 50 MHz facilitate dynamic visualization of patient anatomy with minimal disruption of the surgical work flow. Micro-ultrasound improves spatial resolution over conventional …
