Circulating tumor cells (CTCs) are important targets for treatment and critical surrogate markers when evaluating cancer prognosis and therapeutic response. A sensitive methodology for detecting CTCs in gastric cancer (GC) patients is needed. In this study we demonstrate a device for enrichment and cultivation of CTCs. In total, 22 patients with GC, all(More)
UNLABELLED The aim of the study was the investigation of relationship between cachexia syndrome and serum resistin, adiponectin, and apelin in patients with gastroesophageal cancer (GEC). MATERIAL AND METHODS Adipocytokines concentrations were measured in sera of 85 GEC patients and 60 healthy controls. They were also evaluated in tumor tissue and(More)
PURPOSE The purpose of this study was to evaluate midkine, multipotential cytokine, and growth factor in colorectal cancer (CRC) stratified by tumor location. METHODS Midkine was assessed immunoenzymatically in paired cancerous and noncancerous tissues from 53 CRCs and referred to CRC stage, tumor location, and size, and circulating cytokine levels. (More)
Tumor progression is associated with cell migration, invasion and metastasis. These processes are accompanied by the activation of specific proteases that are either linked to cellular membranes or are secreted into extracellular spaces. TNF-α is known to play an important role in various aspects of tumor progression. The aim of this work was to assess the(More)
BACKGROUND The optimal therapeutic schedule in patients with achalasia is still under discussion. The aim of this study was to review our institution's experience with myotomy and dilation in patients with achalasia. MATERIAL AND METHODS Clinical data were available for 59 patients who had ever had myotomy (n=38), dilation (n=21), or both procedures (n=8)(More)
Introduction. The aim of the study was evaluation of the diagnostic utility of serum oxidized low-density lipoproteins (oxLDL), antibodies against oxLDLs (o-LAB), and CEA as risk markers of colorectal cancer (CRC). Material and Methods. The serum levels of study factors were measured in 73 patients with CRC and in 35 healthy controls who were gender- and(More)
INTRODUCTION Prostaglandin-2 (PGE-2), one of the products of cyclooxygenase-2 (COX-2) induced catalysis, may play a critical role in the carcinogenesis of esophageal squamous cell carcinoma (ESCC). We investigated the efficacy of using serum PGE-2 concentration as a biomarker for this cancer type. MATERIAL AND METHODS Prostaglandin-2 levels were analyzed(More)
Maroon-fronted Parrot (Rhynchopsitta terrisi) is an endangered parrot endemic to pine-oak forests in north-eastern Mexico. According to all present classifications, R. terrisi as well as Rhynchopsitta pachyrhyncha are treated as a separate species based on some morphological and behavioral discrepancies. Despite this formal separation of the two species,(More)
Fatty acyl-CoA esters are extremely important in cellular homeostasis. They are intermediates in both lipid metabolism and post-translational protein modifications. Among these modification events, protein palmitoylation seems to be unique by its reversibility which allows dynamic regulation of the protein hydrophobicity. The recent discovery of an enzyme(More)
