Organochlorine (OC) pesticides have been used broadly in China's past, yet very little is known about their atmospheric concentrations and transport. In this work, air samples were collected in the Taihu Lake Region, China, from July 23 to August 11, 2002, to measure concentrations of OC pesticides in air. The average concentrations of alpha and gamma-(More)
The Th17 subset and IL-17 have been found in increased frequencies within certain tumors. However, their relevance in cancer biology remains controversial. This study aimed to clarify the biological action of IL-17 on hepatocellular carcinoma (HCC). Effects and underlying molecular mechanisms of IL-17 on human HCC were explored in vitro using exogenous(More)
Submucosal tunneling endoscopic resection (STER) can be adequately adopted as an effective treatment for submucosal tumors (SMTs) originating from the muscularis propria (MP) layer at the esophagus and cardia. However, it has been seldom used for gastric SMTs. Our purpose was to evaluate the clinical impact of STER for gastric SMTs arising from the MP(More)
BACKGROUND AND STUDY AIMS Submucosal tunneling endoscopic resection (STER) has become a potential option for the endoscopic treatment of a selected group of patients with submucosal tumors (SMTs) originating from the muscularis propria layer in the upper gastrointestinal tract. The aim of this retrospective study was to analyze the incidence and management(More)
INTRODUCTION In the United States and elsewhere, recreational water quality is monitored for fecal indicator bacteria to help prevent swimming-associated illnesses. Standard methods to measure these bacteria take at least 24 hours to obtain results. Molecular approaches such as quantitative polymerase chain reaction (qPCR) can estimate these bacteria(More)
BACKGROUND Peroral endoscopic myotomy (POEM) has been developed to provide a less-invasive myotomy for achalasia in adults but seldom has been used in pediatric patients. OBJECTIVE To evaluate the feasibility, safety, and efficacy of POEM for pediatric patients with achalasia. DESIGN Single-center, prospective study. SETTING Academic medical center.(More)
BACKGROUND A circular muscle myotomy preserving the longitudinal outer esophageal muscular layer is often recommended during peroral endoscopic myotomy (POEM) for achalasia. However, because the longitudinal muscle fibers of the esophagus are extremely thin and fragile, and completeness of myotomy is the basis for the excellent results of conventional(More)
BACKGROUND Previous studies have indicated that CD151, a hydrophobic protein, forms a functional complex with the proto-oncogene that encodes an N-methyl-N'-nitro-N-nitroso-guanidine (MET) protein (c-Met), and CD151 overexpression reportedly is involved in metastasis/invasion of several tumors. The objective of the current study was to investigate the(More)
OBJECTIVE Renal cell carcinoma (RCC) of 4 cm or less is with a low incidence of multicentricity and metastasis and is usually considered suitable for nephron-sparing surgery (NSS). This study was designed to investigate the distance between extra-pseudocapsule cancer lesions and primary tumors, and to suggest the optimal margin of normal parenchyma in NSS(More)
OBJECTIVE To compare the accuracy of multiparametric magnetic resonance imaging (MP-MRI) with the Partin tables and Memorial Sloan-Kettering (MSK) nomogram for predicting extracapsular extension (ECE) in prostate cancer and to create a tool for clinicians to estimate pathologic ECE risk. METHODS A retrospective review of 112 patients who underwent 3T(More)
