The role of nm23 gene in colorectal carcinogenesis.

The aim of this study was to investigate the correlation of immunohistochemical expression of nm23 gene in colorectal cancer cells with tumor stage according to Dukes, tumor differentiation, occurrence of distant metastases and patient survival. This retrospective study included 100 colorectal cancer patients who underwent surgical treatment. Both pathological and clinical data were analyzed according to sex, age, immunohistochemical expression of nm23, tumor stage, tumor differentiation, occurrence of distant metastases and patient survival.

Relationships between structure and activity of carbon as a multifunctional support for electrocatalysts.

We report on new insights into the relationships between structure and activity of glassy carbon (GC), as a model material for electrocatalyst support, during its anodization in acid solution. Our investigation strongly confirms the role of CFGs in promotion of Pt activity by the "spill-over" effect related to CO(ads) for methanol electrooxidation (MEO) on a carbon-supported Pt catalyst. Combined analysis of voltammetric and impedance behaviour as well as changes in GC surface morphology induced by intensification of anodizing conditions reveal an intrinsic influence of the carbon functionalization and the structure of a graphene oxide (GO) layer on the electrical and electrocatalytic properties of activated GC.

Percutaneous embolization of persistent low-output enterocutaneous fistulas.

Objectives: To present and retrospectively evaluate the technique of percutaneous embolization of chronic enterocutaneous fistulas (ECFs) using n-butyl-2-cyanoacrylate and Lipiodol under fluoroscopic guidance.

Methods: Six patients with a total of seven post-operative low-output ECFs of the large intestine were treated. After fistulography a hydrophilic guide wire and a catheter were advanced through the ECF into the intestine.

Advantages of the spared surgical treatment of the spleen injuries in the clinical conditions.

Background/aims: Aim of this study was to compare clinical, biochemical and hematological parameters of the patients after posttraumatic splenectomy, posttraumatic spleen preservation and auto transplantation and the control group of the patients.

Methodology: The study included data on 169 patients treated at the University Surgery Department, University Hospital Split, from 1998 till 2006. There were 127 male, and 42 female patients, mean age was 40,3 years (range 15-74), 137 of the patients underwent surgery and 32 were treated without operation.

High activity of Pt(4)Mo alloy for the electrochemical oxidation of formic acid.

Surface processes on Pt4Mo alloy well-defined by X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) were studied in acid solution by cyclic voltammetry. It was established that Mo in the alloy is much more resistant toward electrochemical dissolution than pure Mo. During the potential cycling of Pt4Mo surfaces in completely quiescent electrolyte, hydrous Mo-oxide could be generated on Mo sites.
