BACKGROUND A gastro-tracheal fistula following esophagectomy for cancer is a rare but potentially lethal complication. We report the successful surgical closure after failed endoscopic treatment, of a gastro-tracheal fistula following esophago-gastrectomy for cancer after induction chemo-radiotherapy. CASE PRESENTATION A 58 year-old male patient presented with a distal third uT3N1 carcinoma o...

Cross-linked hyaluronic acid gel (CHAG) has been used to prevent postoperative adhesion of abdominal tumorectomy. However, its effect on tumor cells is still unknown. This paper was designed to investigate the effect of CHAG on metastasis and growth of tumor cells. Migration and invasion assays, Western blotting, pull down assay, siRNA interference, and nude mice implantation tumor model were a...

Many corporate events are self-selected, but the relative impact of internal (firm-specific) and external (environmental) influences on discretionary corporate decisions remains largely unknown. In this paper, focusing on corporate debt issuance, we apply the contemporary push-pull theory to establish whether bond issuance are pushed by the firms due to internal considerations, or pulled by the...

BACKGROUND Iron deficiency anemia (IDA) and abdominal pain are commonly seen in a pediatric emergency department (8 and 18% incidence respectively in our center). They are manifestations of a wide variety of diseases ranging from benign to immediately life-threatening. Trichobezoar is an under-diagnosed entity that has to be considered in children and adolescents, expecially female, suffering f...

Association of some plasma membrane bicarbonate transporters with carbonic anhydrase enzymes forms a bicarbonate transport metabolon to facilitate metabolic CO(2)-HCO(3)(-) conversions and coupled HCO(3)(-) transport. The transmembrane carbonic anhydrase, CAIX, with its extracellular catalytic site, is highly expressed in parietal and other cells of gastric mucosa, suggesting a role in acid sec...

Strengthening muscles of the back may have various implications for improving functions of daily living, aiding in the transfer of power in throwing, and assist in injury prevention of the shoulder complex. While several versions of the pull-up exist, there is currently no literature comparing their differences. The purpose of this investigation was to compare the electromyographical activity o...

The Klebsiella oxytoca pullulanase secreton (type II secretion system) components PulM and PulL were tagged at their N termini with green fluorescent protein (GFP), and their subcellular location was examined by fluorescence microscopy and fractionation. When produced at moderate levels without other secreton components in Escherichia coli, both chimeras were envelope associated, as are the nat...

The objectives of this study were to determine the mechanical work, the power output, and the angular kinematics of the lower limb and the linear kinematics of the barbell during the first and second pulls in the snatch lift event of the 2010 Women's World Weightlifting Championship, an Olympic qualifying competition, and to compare the snatch performances of the women weightlifters to those re...
