OBJECTIVES To explore the changes of multifocal electroretinograms (mfERG) before and after retinal detachment surgery and to evaluate its clinical significance. METHODS Twenty-three patients (23 eyes) with rhegmatogenous retinal detachment underwent mfERG before and after surgery. The latencies and average response densities of N(1)-wave and P(1)-wave of(More)
Gankyrin is an important oncoprotein that is overexpressed in human hepatocellular carcinoma (HCC). However, the gradual alteration of Gankyrin in successive stages during human HCC development and the mechanism of Gankyrin-mediated hepatocarcinogenesis remain largely unknown. In this study, we evaluated the pattern and level of Gankyrin protein expression(More)
Myocardial ischemia reperfusion (I/R) can induce altered expression of microRNAs (miRNAs). The miRNAs—miR-15a, miR-15b and miR-16 have been shown to play a role in apoptosis, although not in cardiac-related models. We investigated the roles of miR-15b in hypoxia/reoxygenation (H/R)-induced apoptosis of cardiomyocytes. Quantitative real time polymerase chain(More)
OBJECTIVE To compare temperature curve and ablation zone between 915- and 2450-MHz cooled-shaft microwave antenna in ex vivo porcine livers. MATERIALS AND METHODS The 915- and 2450-MHz microwave ablation and thermal monitor system were used in this study. A total of 56 ablation zones and 280 temperature data were obtained in ex vivo porcine livers. The(More)
This study investigated whether pharmacological postconditioning with lactic acid and hydrogen rich saline can provide benefits similar to that of mechanical postconditioning. To our knowledge, this is the first therapeutic study to investigate the co-administration of lactic acid and hydrogen. SD rats were randomly divided into 6 groups: Sham, R/I, M-Post,(More)
The effects of local myocardial administration of lactic acid and low-dose edaravone were investigated to determine if this combination provides benefits similar to mechanical postconditioning. We randomly divided 108 rats into 6 groups: sham, reperfusion injury, postconditioning (Post), lactic acid (Lac), low-dose edaravone (Eda), and lactic acid +(More)
The aim of the present study was to investigate whether a gradually increasing reperfusion algorithm, in which the brief reperfusion was lengthened as the duration of each reperfusion/reocclusion cycle remained fixed, enhances cardioprotection. Rats were randomized into 5 groups: the sham, reperfusion injury (R/I), gradually decreased reperfusion (GDR;(More)
Laparoscopic radial nephrectomy (LRN) and microwave ablation (MWA) are optional treatment for renal cell carcinoma (RCC). However, the comparative study with two techniques remains lacking. The aim of this study was to evaluate midterm results of MWA vs. LRN in patients with small RCC. A total of 426 patients with ≤ 4 cm RCC were included from April 2006 to(More)
