OBJECTIVE Antiacid drugs, including omeprazole and ranitidine, were prescribed to Helicobacter pylori-infected subjects in combination with antibiotics during eradication treatment. Several reports suggest that these drugs have additional pharmacological properties, such as antineutrophil, antiapoptotic and antioxidant characteristics. The aim of this work(More)
BACKGROUND Pro-inflammatory cytokines, such as tumour necrosis factor (TNF)-alpha, are known to be involved in the establishment of insulin resistance. Insulin resistance plays a key role in the development of obesity-related pathologies, such as type 2 diabetes and non-alcoholic fatty liver disease (NAFLD). The state of chronic inflammation associated with(More)
Analysis of blood and lymphatic vessel in colorectal cancer is controversial in the literature, possibly due to variations in the methods of analysis. In this study, it was aimed to search for a reliable approach in the quantification of angio- and lymphangiovascular density and area as a prognostic factor and to compare such vessel counts in normal mucosa,(More)
Blood and lymphatic vessel proliferation is essential for tumor growth and progression. Most colorectal carcinomas develop from adenomas (adenoma-carcinoma sequence) in a process due to accumulation of molecular genetic alterations. About 5% of adenomatous polyps are expected to become malignant, but data on the differential angiogenic patterns of these(More)
OBJECTIVE Helicobacter pylori infection is related to gastric cancer development, and chronic inflammation is presumed to be the main cause. The aim of the present study was to evaluate the influence of H. pylori cagA, vacA, iceA, and babA genotypes on COX-2, IL-1beta, and IL-8 expression. MATERIAL AND METHODS Of the 217 patients included in the study, 26(More)
The aim of this study was to investigate whether the AgNOR technique could be helpful for the cytologic diagnosis of neoplastic and non-neoplastic urinary tract lesions. We analysed the AgNOR pattern in urinary cytology in samples from 70 patients. In every case the average number of silver precipitations per nucleus was counted and the range between the(More)
The AgNor reaction was performed on effusions and peritoneal washings, and the silver dots were counted on normal or reactive mesothelial cells vs. carcinomatous cells, ascertained by previous HE staining. The mean values were 1.64 for the former (n = 20) and 4.90 for the latter (n = 10). The intersection between the two group distributions was 2.78,(More)
