Repeated sampling of a drug solution that is recirculated through a perfused body increases the rate of drug disappearance from the perfusate. When the volume of the drug solution (VT) is maintained constant by addition of drug-free perfusate after sampling, the measured drug concentration (Ci) can be corrected for drug removed in previous samples by using(More)
In China, direct-reverse flotation is proved to be applicable to most phosphate ores. However, because the ratio of froth product is generally high, current direct-reverse technology faces challenges in terms of high reagent consumptions and cost. A new gravity and flotation combined process has been developed for the recovery of collophanite from(More)
BACKGROUND Most studies have found that osteopontin (OPN) expression level is related to the poor prognosis of gastric cancer. However, few studies have examined the relationship between OPN expression and gastric precancerous diseases, and the potential role of OPN in the formation and development of GC. We investigated the relationships between serum OPN(More)
OBJECTIVE The present study aimed to investigate the effectiveness of parenteral nutritional support with ω-3 PUFAs-based lipid emulsions in patients after liver resection. METHODS A total of 119 patients were randomly assigned to the immunonutrition (IM) group (n = 59) and control group (n = 60). The IM group was continuously given Omegaven(®) 10% 100(More)
BACKGROUND We investigated the prognostic significance of carcinoembryonic antigen (CEA) and vascular endothelial growth factor (VEGF) and their associations with clinicopathological features in patients with sigmoid colon carcinoma (SCC). METHODS We retrospectively reviewed patients with SCC treated with curative surgery from January 2001 to June 2010 at(More)
BACKGROUND Extrahepatic cholangiocarcinoma (ECCA) is a rare but devastating malignancy. Up to 90% of patients presenting with ECCA have no identifiable risk factors. The base excision repair (BER) pathway has a principal role in the repair of mutations caused by oxidized or reduced bases. The XRCC1 is one of the key proteins in the BER pathway. In this(More)
In this paper, we focus on multi -- scale modeling and simulation of piezo electric composite materials, Piezo electricity is the ability of some materials to generate an electric field or electric potential in response to applied mechanical stress.And it isreversible in piezoelectric materials.This property can be reflected in the constitutive relations as(More)
OBJECTIVE To investigate the association between serum concentration of insulin-like growth factor (IGF) and the risk of pancreatic cancer (PaC). METHODS We identified eligible studies in Medline and EMBASE databases (no reference trials from 2014 to 2016) in addition to the reference lists of original studies and review articles on this topic. A summary(More)
OBJECTIVES To examine the feasibility of three-dimensional computed tomography (3D-CT) image fusion in facilitating assessment of the ablative margin (AM) after radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC). METHODS This study involved 75 patients with solitary HCC who underwent RFA. The AM was evaluated using 3D-CT image fusion. All(More)
Simple magnetic separation for a certain magnetite mine with ultrafine disseminated lean ores has resulted in low performance, as the fine sizes and aggregation of ground mineral particles have caused inefficient recovery of the ultrafine minerals. In this study, we attempt to increase the apparent sizes of target mineral particles, and improve the(More)
