We present an adaptive mimetic finite difference method for the approximate solution of variational inequalities. The adaptive strategy is based on a heuristic hierarchical type error indicator. Numerical experiments that validate the performance of the adaptive MFD method are also presented. 1 The Obstacle Problem Throughout the paper we will use standard notations for Sobolev spaces, norms an...

The aim of this study was to explore if estimates of renal function could explain variability of (123)I-metaiodobenzylguanidine ((123)I-MIBG) assessed myocardial sympathetic activity. Furthermore estimates of renal function were compared to (123)I-MIBG as predictors of cardiac death in chronic heart failure (CHF). Semi-quantitative parameters of (123)I-MIBG myocardial uptake and washout were ca...

Toxplasmosis is an important zoonotic disease caused by protozoan parasite Toxoplasma gondii. Transmission of the disease is mainly by ingestion of food or water contaminated with oocysts. Congenital toxoplasmosis occurs from the transplacental passage of from mother to fetus. Diagnosis of toxoplasmosis can be established by the direct detection of the parasite or serological methods. Among 150...

Previous studies have shown that the expression of miR-211 was downregulated in hepatocellular carcinoma (HCC). However, the molecular function and mechanism of miR-211 in HCC growth and invasion are largely unclear. We found that miR-211 is downregulated in HCC tissues and cell lines, respectively. Further results showed that low miR-211 associated with TNM stage, vein invasion status, and poo...

To determine the efficacy of Venastent - a novel iliac vein stent for non-thrombotic lesions (NIVLs). From October 2018 to January 2021, 256 NIVL patients were recruited at 19 Chinese hospitals. A randomised controlled trial was conducted compare new stent-Venastent (Tianhong China) with Zilver (Cook USA). All allocated randomly two groups: experimental group used Venastent, while control recei...

BACKGROUND Myocardial ischemia and reperfusion are associated with increased production of endothelin (ET)-1. METHODS AND RESULTS We examined the effects of BQ-123, a selective ET(A) receptor antagonist, in 80 patients. All patients were randomly allocated to an intracoronary infusion of saline or BQ-123 (6 micromol/L over 20 minutes). The reference group consisted of 20 patients undergoing c...
