To assess the detection rate of nutcracker syndrome in children with isolated hematuria, renal Doppler ultrasound examinations were routinely performed on 216 consecutive (176 microscopic hematuria and 40 gross hematuria). Renal was also 32 healthy normal children. The peak velocity (PV) measured at hilar portion left vein (LRV) LRV between aorta superior mesenteric artery. PV aortomesenteric (P=0.003) ratios significantly higher than children, while not different. If a ratio least 4.1 (the...

To describe color Doppler ultrasonographic (US) findings in livers of neonates with biliary atresia (BA) and to compare them US non-BA control subjects.Institutional review board approval was obtained; acquisition informed consent exempted. were retrospectively reviewed 64 patients neonatal cholestasis 19 subjects. BA confirmed 29 35 patients, respectively. Three pediatric radiologists assessed images, independently documented their findings, resolved discrepancies by consensus. Triangular...

<b>Purpose:</b> To assess the variability of shear wave velocity (SWV) from acoustic radiation force impulse (ARFI) elastography at various depths using different frequencies. <b>Materials and Methods:</b> ARFI elasticity phantom normal liver was performed (2 – 5 cm) with convex (1 4 MHz) linear (4 9 probes. Ten valid SWV measurements each depth were performed. This repeated ten times in eight healthy volunteers (M:F = 3:5, age 20 34 years). The mean value standard deviation calculated....

To measure shear wave velocities (SWVs) by acoustic radiation force impulse (ARFI) ultrasound elastography in normal kidneys and hydronephrotic young children to compare SWVs between the hydronephrosis grades.This study was approved an institutional review board, informed consent obtained from parents of all included. Children under age 24 months were prospectively enrolled. Hydronephrosis grade evaluated on ultrasonography, three valid ARFI measurements attempted using a high-frequency...

The purpose of this study was to assess the diagnostic performance transient elastography and sonography for noninvasive evaluation liver fibrosis in infants with biliary atresia.Forty-seven atresia who underwent both before surgery were included study. Two types elastographic probes used: an M probe, which is used general adult population; S specific children. Transient measurements sonographic findings such as triangular cord thickness hepatic artery portal vein diameters compared METAVIR...

Purpose:To evaluate the effect of platelet-rich plasma (PRP) eye drops in treatment recurrent corneal erosions (RCE).Methods: A total 47 eyes were included this retrospective study.Clinical records 20 consecutive patients with RCE who had been treated conventional lubricant (conventional group) from June 2006 to December 2008 and 27 autologous PRP addition (PRP January 2009 September 2014 reviewed.Major minor recurrences recorded compared between two groups.Results: This study 31 men 16...

Controlled attenuation parameter (CAP) is a recently introduced, non-invasive and quantitative method to evaluate hepatic steatosis demonstrated in adults, but limited obesity not well evaluated children. The aim of this study was investigate the diagnostic performance for assessing grades using CAP children based on MR proton density fat fraction (PDFF).Children non-alcoholic fatty liver disease (NAFLD) who were assessed PDFF enrolled retrospectively. Hepatic 0-3 classified according cutoff...

Abstract Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), is often exacerbated upon coinfection, but the underlying immunological mechanisms remain unclear. Here, to elucidate these mechanisms, we use an Mtb and lymphocytic choriomeningitis virus coinfection model. Viral significantly suppresses Mtb-specific IFN-γ production, with elevated bacterial loads hyperinflammation in lungs. Type I IFN signaling blockade rescues response ameliorates lung immunopathology. Single-cell...

This paper explores the potential use of machine learning models in crude oil realized volatility forecasting through a variety empirical analyses and robustness checks. Although conventional Heterogeneous Autoregressive (HAR) model is widely accepted, with HAR factors can significantly improve its performance. We also found that macroeconomic variables such as supply factors, implied indices uncertainty be useful volatility.

To correlate a triangular area of high signal intensity in the porta hepatis on T2-weighted magnetic resonance (MR) cholangiograms biliary atresia with ultrasonographic (US) and histopathologic findings portal mass observed during Kasai procedure.Twenty-one consecutive neonates infants (age range, 13-88 days; mean age, 59 days) cholestasis underwent US single-shot MR cholangiography. In 12 patients diagnosed at examination, cholangiographic were correlated mass.At US, eight had round,...

Objective: To evaluate the relationship between anthropometric measurements and renal length volume measured with ultrasound in Korean children who have morphologically normal kidneys, to create simple equations estimate sizes using measurements. Materials Methods:We examined 794 under 18 years of age including a total 394 boys 400 girls without problems.The maximum (L) (cm), orthogonal anterior-posterior diameter (D) (cm) width (W) each kidney were on ultrasound.Kidney was calculated as...

Abstract Purpose: The aim of this study is to report the common location intrathyroid ectopic thymus and describe corresponding sonographic appearances in children. Methods: We retrospectively reviewed clinical data neck or thyroid ultrasonography (US) findings children from January 2003 May 2010. Intrathyroid lesions showing hypoechogenicity with multiple linear echogenic branching structures punctate foci were considered thymus. US features (location, side, size, shape) indication for...

A deficiency in bone morphogenetic protein receptor type 2 (BMPR2) signaling is a central contributor the pathogenesis of pulmonary arterial hypertension (PAH). We have recently shown that endothelial-specific Bmpr2 deletion by novel L1Cre line resulted hypertension. SMAD1 one canonical signal transducers BMPR2 pathway, and its reduced activity has been to be associated with PAH. To determine whether an important downstream mediator PAH, we analyzed phenotypes Smad1 -conditional knockout...
