When chronic aortic dissection (CAD) is associated with aortic dilatation, the risk of aortic rupture increases. We report a case of CAD complicated by acute aortitis that was depicted in contrast-enhanced magnetic resonance imaging (MRI). Contrast-enhanced MRI allows early detection of subtle changes in the aortic wall as well as disease activity. Inflammation of aortic wall in the aortic diss...

Thyroid hormones (THs) play a pivotal role in cardiac homeostasis. TH imbalances alter cardiac performance and ultimately cause cardiac dysfunction. Although short-term hyperthyroidism typically leads to heightened left ventricular (LV) contractility and improved hemodynamic parameters, chronic hyperthyroidism is associated with deleterious cardiac consequences including increased risk of arrhy...

Additive manufacturing (AM) enables diversity in honeycomb structure configuration, which benefits optimization of the structure. In present study, we proposed two locally enhanced triangular structures to improve in-plane compressive performance by avoiding diagonal fracture band. The behaviors and failure mechanism original made 316L steel were studied experiments numerical simulations. resul...

This paper presents a magnetic resonance imaging (MRI)-based virtual cystoscopy system, which extracts the bladder wall from T1-weighted MR images where the wall is enhanced while the urine and surrounding fat tissues are suppressed by a fully non-invasive imaging procedure. The system analyzes the extracted wall and detects abnormal features automatically. Test results are encouraging by FROC ...

Lichens are unique extremophilic organisms due to their phenomenal resistance adverse environmental factors, including ultraviolet (UV) irradiation. Melanization plays a special role in the protection of lichens from UV-B stress. In present study, we analyzed binding melanins with components cell walls mycobiont upper cortex melanized lichen thalli Lobaria pulmonaria. Using scanning electron an...

Abstract This paper aims to develop and validate an analytical equation predict the concentration of residual chlorine exiting a typical pipe junction. In order investigate trend incoming flow rates before leaving junction, experiments with inflow (North West) ranging from 0.18 2.17 L/s, Reynolds numbers 14,324 110,780, free concentrations 0.5 1.80 mg/L were performed. The results showed that f...

Introduction: Double Inversion Recovery or Saturation Band Black Blood imaging has been used to image vessel wall morphology and plaque composition. However, due to their reliance on blood inflow, problems arise at areas with slow or in-plane flow. Recently, the feasibility of vessel wall imaging using a flow-insensitive technique, Susceptibility Weighted Imaging (SWI), has been demonstrated [1...
