BACKGROUND Tobacco smoking is the most important risk factor for chronic obstructive pulmonary disease (COPD) development. Inhaled cigarette smoke can induce tumor necrosis factor-alpha (TNF-alpha) production by alveolar macrophages, which in turn may enhance the production of metalloproteinases (MMPs). MMPs have been involved in mediating airway(More)
Corpora amylacea (CA) are glycoprotein-based depositions that accumulate in the normal aging brain or consecutively to different neuro-degenerative diseases. Although controversies still exists in what it regards their origins and functions, their morphology is described simply as round basophilic entities based on bi-dimensional observations. The aim of(More)
Autophagy has emerged not only as an essential repair mechanism to degrade damaged organelles and proteins but also as a major player in protection of tumor cells from multiple stresses. It was shown that autophagy gene polymorphisms are correlated with development of chronic inflammatory lesions, which represent a risk factor for colorectal tumors. In this(More)

In the recent years, statistically significant associations between rheumatoid arthritis (RA) and periodontal disease have been identified. Emerging as a chronic inflammatory joint disease, RA displays various features and pathogenetic events similar to chronic periodontitis (CP). The purpose of this study was to evaluate the utility of determining systemic(More)
Pancreatic disorders have a high prevalence worldwide. Despite the fact that screening methods became more effective and the knowledge we have nowadays about pancreatic diseases has enhanced, their incidence remains high. Our purpose was to determine whether single nucleotide polymorphism (SNP) of VEGFR-2/KDR (vascular endothelial growth factor receptor(More)
Simultaneous presence of an epithelial and lymphoid tumor of the digestive tract is quite rarely met in literature. In this paper, we describe a case which presented such an association. Diagnosis was established by histological study, followed by immunohistochemistry. It is a synchronous colon tumor, associating a non-Hodgkin's lymphoma to a colon(More)
The pleomorphic adenoma, known also as mixed tumor of epithelioma with reshuffling stroma, is the most frequent salivary gland tumor, representing 45-75% of the total salivary gland tumors. In our study, we have investigated the immunohistochemical expression of E-cadherin and alpha-smooth muscle actin (α-SMA) in 15 cases of pleomorphic adenoma of salivary(More)
AIM Gastric carcinoma shows considerable variation in the histological pattern and degree of differentiation. The aim of the study was to assess especially the morphological differences between gastric carcinomas revealing one morphological feature and those including two morphological features. MATERIALS AND METHODS Two groups of patients were selected:(More)
