Fishes and their parasites in the water district of Massaciuccoli (Tuscany, Central Italy).

This study has been conducted in the district of Massaciuccoli (lake, marsh and reclaimed areas with drainage channels) in Tuscany region (Central Italy). The aim of the research was to detect the presence of parasites in fishes, in particular of Opisthorchis felineus, which causes an important zoonosis. Between 2010-2012, the health status of 381 fishes was monitored, morphometric characteristics were determined, and parasites were searched for and identified.

West Nile seroprevalence study in Bolivian horses, 2011.

West Nile virus (WNV) is a mosquito-borne virus belonging to the family Flaviviridae included in the Japanese encephalitis antigenic complex (JEAC). A seroepidemiological study was carried out in 2011 using 160 horse sera collected from different areas of Bolivia to investigate the presence of WNV antibody. A high proportion (59.

Calodium hepaticum (Nematoda: Capillaridae) in a red fox (Vulpes vulpes) in Italy with scanning electron microscopy of the eggs.

Calodium hepaticum (Bancroft, 1893) Moravec, 1982 (syn. Capillaria hepatica) is a cosmopolitan capillariid nematode, infecting mainly rodents and occasionally other mammals, including humans. Reports of C.

Expression profiling of angiogenic genes for the characterisation of colorectal carcinoma.

The development of new blood and lymphatic vessels is a crucial event for cancer growth, metastatic spread and relapse after therapy. In this work, the expression levels of chemokines, angiogenic and angiostatic factors and their receptors were determined in paired mucosal and tumour samples of patients with colorectal carcinoma and correlated with clinical and histological parameters by advanced multivariate analyses. The most important predictors to discriminate between tumour and paired normal mucosa turned out to be the levels of expression of plexin-A1 and stromal cell-derived factor 1 (SDF-1), the former overexpressed and the latter downregulated in tumours.

Different estrogen receptor beta expression in distinct histologic subtypes of lung adenocarcinoma.

Adenocarcinoma is becoming the most common histologic type of lung cancer in both sex. Although most cases are seen in smokers, it develops more frequently than other histologic types in individuals who have never smoked. This evidence suggests that other putative etiologic factors, such as sex hormones, need to be investigated.

Vulpes vulpes: a possible wild reservoir for zoonotic filariae.

Foxes (Vulpes vulpes, n = 132) killed during the hunting seasons 2005-2006 in Central Italy (Tuscany region) were examined in order to investigate the possible importance of this animal as a wild reservoir for zoonotic filariae. In each specimen adult worms of Dirofilaria immitis and hematic microfilariae were searched for. Species identification was performed by morphology, morphometry, the Barka staining technique applied to pulmonary and splenic blood smears, and, finally, by molecular diagnostics -- polymerase chain reaction (PCR) and sequencing.

WWOX expression in different histologic types and subtypes of non-small cell lung cancer.

Purpose: Non-small cell lung cancer (NSCLC) has heterogeneous histopathologic classification and clinical behavior and very low survival rate. WWOX (WW domain-containing oxidoreductase) is a tumor suppressor gene, and its expression is altered in several cancers. The purpose of this study is to better define the role of WWOX in NSCLC tumorigenesis and progression by determining its pathogenetic and prognostic significance.

Applications of tissue microarray technology in immunohistochemistry: a study on c-kit expression in small cell lung cancer.

Tissue microarray technology allows the immediate evaluation of molecular profiles of numerous different tissues, with savings of money and time. It was created for rapid, large-scale molecular studies, and the main concern regarding its possible broad acceptance is that the analysis of tissue microarrays instead of whole tissue sections may lead to false negative or positive results because of tissue heterogeneity. In the present study, we analyzed in 54 small cell lung cancers, by immunohistochemistry, the expression of the antigen c-kit, which seems to be important in these neoplasms' tumorigenesis, and compared the staining obtained on whole sections with that of the corresponding tissue microarrays.
