Abstract
Hepatitis C virus (HCV) leads to persistent infection. Viral clearance can be obtained through pharmacological treatment or spontaneously. After viral clearance, anti-HCV antibodies (Abs) slowly decline and finally disappear. Subjects with a resolved HCV infection are reactive to anti-HCV screening assays for a long time. These subjects pose a diagnostic challenge, and therefore, a more accurate interpretation of laboratory tests is needed for cases with resolved HCV infection. However, the performances of anti-HCV screening assays against declining anti-HCV Abs have not been assessed. Here we evaluated 1509 samples with different screening assays. Screening assays provided discrepant results in patients with waning Abs. The identification of signal-to-cut-off values indicative of waning Abs for each anti-HCV assay could avoid unnecessary confirmatory tests and reduce the impact of misdiagnosis.

Abstract
INTRODUCTION Laboratory diagnosis of HIV infection is essential for the prevention of infection and the identification of infected individuals who could benefit from highly active antiretroviral therapy. Since the release of the first assays for the detection of anti-HIV antibodies, the technology of immunoassays has improved. AREAS COVERED Fourth generation assays - simultaneously detecting HIV p24 antigen and antibodies - have been developed and have been a major improvement in the detection of HIV infection, with a reduction of the diagnostic window. Studies have provided definite evidence for their clinical utility. Combination assays with separate results for anti-HIV antibodies and p24 antigen have been developed. Expert Commentary: In conclusion, fourth generation assays are an effective tool for the laboratory diagnosis of HIV infection. The ADVIA Centaur HIV Ag/Ab Combo assay is in line with most recent fourth generation assays and its clinical utility has been assessed.

Abstract
BACKGROUND Radical external beam radiotherapy (EBRT) is a standard treatment for prostate cancer patients. Despite this, the rate of intraprostatic relapses after primary EBRT is still not negligible. There is no consensus on the most appropriate management of these patients after EBRT failure. For these patients, local salvage therapy such as radical prostatectomy, cryotherapy, and brachytherapy may be indicated. OBJECTIVE The objectives of this review were to analyze the eligibility criteria for careful selection of appropriate patients and to evaluate the oncological results and complications for each method. METHODS A review of the literature was performed to identify studies of local salvage therapy for patients who had failed primary EBRT for localized prostate cancer. RESULTS Most studies demonstrated that local salvage therapy after EBRT may provide long-term local control in appropriately selected patients, although toxicity is often significant. CONCLUSIONS Our results suggest that for localized prostate cancer recurrence after EBRT, the selection of a local treatment modality should be made on a patient-by-patient basis. An improvement in selection criteria and an integrated definition of biochemical failure for all salvage methods are required to determine which provides the best oncological outcome and least comorbidity.

Abstract
Background A relationship between low levels of serum vitamin D and respiratory infections has been established. No study has examined the frequency and clinical relevance of vitamin D deficiency in patients with primary ciliary dyskinesia (PCD). Methods Vitamin D levels were measured in 22 PCD patients (7 females, 10.5 years, range, 2–34 years). In PCD, pulmonary function tests (PFTs), sputum microbiology, self-reported physical activity (PA) level, and quality of life (QoL) by means of the Saint George’s Respiratory Questionnaire (SGRQ), were also assessed. Results Seventy-two percent of PCD patients were vitamin-D deficient-to-insufficient and 28% were sufficient. No differences in PFTs parameters were found between vitamin D deficiency-to-insufficiency and sufficiency groups. Patients with vitamin D deficiency-to-insufficiency had significantly higher SGRQ total scores, and thus poorer QoL (p = 0.03). Seventy-nine percent of PCD subjects had limitations in performing vigorous activities, and 53% performed less than 3 hours of PA per week. Vitamin D deficiency-to-insufficiency and sufficiency groups did not show any differences in age at PCD diagnosis or at onset of respiratory symptoms, BMI, atopy, current asthma or bronchiectasis. However, 79% of patients with bronchiectasis had vitamin D deficiency-to-insufficiency. No differences were found in the rate of positive sputum cultures and in the number of antibiotic courses between the two groups. Conclusions Hypovitaminosis D is common in PCD patients, and is associated with poorer QoL. We recommend the assessment and treatment of hypovitaminosis D to be included in the routine management of PCD.

Abstract
BACKGROUND/AIM Several efforts have been made to find biomarkers that could help clinicians to preoperatively determine prostate cancer (PCa) pathological characteristics and choose the best therapeutic approach, avoiding over-treatment. On this effort, prostate cancer antigen 3 (PCA3), prostate health index (phi) and sarcosine have been presented as promising tools. We evaluated the ability of these biomarkers to predict the pathologic PCa characteristics within a prospectively collected contemporary cohort of patients who underwent radical prostatectomy (RP) for clinically localized PCa at a single high-volume Institution. MATERIALS AND METHODS The prognostic performance of PCA3, phi and sarcosine were evaluated in 78 patients undergoing RP for biopsy-proven PCa. Receiver operating characteristic (ROC) curve analyses tested the accuracy (area under the curve (AUC)) in predicting PCa pathological characteristics. Decision curve analyses (DCA) were used to assess the clinical benefit of the three biomarkers. RESULTS We found that PCA3, phi and sarcosine levels were significantly higher in patients with tumor volume (TV)≥0.5 ml, pathologic Gleason sum (GS)≥7 and pT3 disease (all p-values≤0.01). ROC curve analysis showed that phi is an accurate predictor of high-stage (AUC 0.85 [0.77-0.93]), high-grade (AUC 0.83 [0.73-0.93]) and high-volume disease (AUC 0.94 [0.88-0.99]). Sarcosine showed a comparable AUC (0.85 [0.76-0.94]) only for T3 stage prediction, whereas PCA3 score showed lower AUCs, ranging from 0.74 (for GS) to 0.86 (for TV). CONCLUSION PCA3, phi and sarcosine are predictors of PCa characteristics at final pathology. Successful clinical translation of these findings would reduce the frequency of surveillance biopsies and may enhance acceptance of active surveillance (AS).

Abstract
In humans, IL-17 is a proinflammatory cytokine that plays a key role in the clearance of extracellular bacteria promoting cell infiltration and production of several cytokines and chemokines. Here, we report on three Ciona intestinalis IL-17 homologues (CiIL17-1, CiIL17-2, CiIL17-3). The gene organization, phylogenetic tree and modeling supported the close relationship with the mammalian IL-17A and IL-17F suggesting that the C. intestinalis IL-17 genes share a common ancestor in the chordate lineages. Real time PCR analysis showed a prompt expression induced by LPS inoculation suggesting that they are involved in the first phase of inflammatory response. In situ hybridization assays disclosed that the genes transcription was upregulated in the pharynx, the main organ of the ascidian immune system, and expressed by hemocytes (granulocytes and univacuolar refractile granulocyte) inside the pharynx vessels.

Abstract
The most promising approach to improve the specificity of prostate-specific antigen (PSA) test relies on the measurement of different molecular isoforms of PSA in serum. Currently, in men with a total PSA (tPSA) level between 2 and 10 ng/mL, measurement of %fPSA (free to total PSA ratio ×100) is used as reflex testing to better distinguish between malignant and benign prostate disease. Recently, Beckman Coulter developed the prostate health index (PHI) and several studies suggested that this test may improve the diagnostic ability of %fPSA.We performed a meta-analysis to evaluate the usefulness of PHI compared with %fPSA in the detection of prostate cancer (PCa) at first biopsy in men with tPSA "gray" levels of 2-10 ng/mL. Data on sensitivity and specificity were extracted from 8 eligible studies. Only observational studies comparing the diagnostic ability of PHI and %fPSA in tPSA range of 2-10 ng/mL were included. A total of 8 studies involving 2969 patients with a tPSA range of 2-10 ng/mL undergoing first biopsy were included in this meta-analysis. Biopsy-confirmed PCa was detected in 1287 (43.3%) men. Selected studies determined both PHI and %fPSA as a reflex test. The areas under curve (AUCs) of PHI and %fPSA were 0.74 (95% confidence interval [CI], 0.70-0.77) and 0.63 (95% CI, 0.58-0.67), respectively. Meta-regression analysis confirmed the superiority of PHI which showed, compared with %fPSA, a relative diagnostic odds ratio of 2.81 (95% CI, 2.19-3.6; P < 0.0001). In conclusion, PHI instead of %fPSA as a reflex test in men with tPSA "gray" levels is a better predictor of positive first biopsy and can offer a reduction in unnecessary biopsies.

Abstract
Many efforts to reduce prostate specific antigen (PSA) overdiagnosis and overtreatment have been made. To this aim, Prostate Health Index (Phi) and Prostate Cancer Antigen 3 (PCA3) have been proposed as new more specific biomarkers. We evaluated the ability of phi and PCA3 to identify prostate cancer (PCa) at initial prostate biopsy in men with total PSA range of 2–10 ng/ml. The performance of phi and PCA3 were evaluated in 300 patients undergoing first prostate biopsy. ROC curve analyses tested the accuracy (AUC) of phi and PCA3 in predicting PCa. Decision curve analyses (DCA) were used to compare the clinical benefit of the two biomarkers. We found that the AUC value of phi (0.77) was comparable to those of %p2PSA (0.76) and PCA3 (0.73) with no significant differences in pairwise comparison (%p2PSA vs phi p = 0.673, %p2PSA vs. PCA3 p = 0.417 and phi vs. PCA3 p = 0.247). These three biomarkers significantly outperformed fPSA (AUC = 0.60), % fPSA (AUC = 0.62) and p2PSA (AUC = 0.63). At DCA, phi and PCA3 exhibited a very close net benefit profile until the threshold probability of 25%, then phi index showed higher net benefit than PCA3. Multivariable analysis showed that the addition of phi and PCA3 to the base multivariable model (age, PSA, %fPSA, DRE, prostate volume) increased predictive accuracy, whereas no model improved single biomarker performance. Finally we showed that subjects with active surveillance (AS) compatible cancer had significantly lower phi and PCA3 values (p<0.001 and p = 0.01, respectively). In conclusion, both phi and PCA3 comparably increase the accuracy in predicting the presence of PCa in total PSA range 2–10 ng/ml at initial biopsy, outperforming currently used %fPSA.

Abstract
Background The human ERBB2 gene is frequently amplified in breast tumors, and its high expression is associated with poor prognosis. We previously reported a significant inverse correlation between Myc promoter-binding protein-1 (MBP-1) and ERBB2 expression in primary breast invasive ductal carcinoma (IDC). MBP-1 is a transcriptional repressor of the c-MYC gene that acts by binding to the P2 promoter; only one other direct target of MBP-1, the COX2 gene, has been identified so far. Methods To gain new insights into the functional relationship linking MBP-1 and ERBB2 in breast cancer, we have investigated the effects of MBP-1 expression on endogenous ERBB2 transcript and protein levels, as well as on transcription promoter activity, by transient-transfection of SKBr3 cells. Reporter gene and chromatin immunoprecipitation assays were used to dissect the ERBB2 promoter and identify functional MBP-1 target sequences. We also investigated the relative expression of MBP-1 and HDAC1 in IDC and normal breast tissues by immunoblot analysis and immunohistochemistry. Results Transfection experiments and chromatin immunoprecipitation assays in SKBr3 cells indicated that MBP-1 negatively regulates the ERBB2 gene by binding to a genomic region between nucleotide −514 and −262 of the proximal promoter; consistent with this, a concomitant recruitment of HDAC1 and loss of acetylated histone H4 was observed. In addition, we found high expression of MBP-1 and HDAC1 in normal tissues and a statistically significant inverse correlation with ErbB2 expression in the paired tumor samples. Conclusions Altogether, our in vitro and in vivo data indicate that the ERBB2 gene is a novel MBP-1 target, and immunohistochemistry analysis of primary tumors suggests that the concomitant high expression of MBP-1 and HDAC1 may be considered a diagnostic marker of cancer progression for breast IDC.

Abstract
BACKGROUND Prostate health index (phi) and prostate cancer antigen 3 (PCA3) have been recently proposed as novel biomarkers for prostate cancer (PCa). We assessed the diagnostic performance of these biomarkers, alone or in combination, in men undergoing first prostate biopsy for suspicion of PCa. METHODS One hundred sixty male subjects were enrolled in this prospective observational study. PSA molecular forms, phi index (Beckman coulter immunoassay), PCA3 score (Progensa PCA3 assay), and other established biomarkers (tPSA, fPSA, and %fPSA) were assessed before patients underwent a 18-core first prostate biopsy. The discriminating ability between PCa-negative and PCa-positive biopsies of Beckman coulter phi and PCA3 score and other used biomarkers were determined. RESULTS One hundred sixty patients met inclusion criteria. %p2PSA (p2PSA/fPSA × 100), phi and PCA3 were significantly higher in patients with PCa compared to PCa-negative group (median values: 1.92 vs. 1.55, 49.97 vs. 36.84, and 50 vs. 32, respectively, P ≤ 0.001). ROC curve analysis showed that %p2PSA, phi, and PCA3 are good indicator of malignancy (AUCs = 0.68, 0.71, and 0.66, respectively). A multivariable logistic regression model consisting of both the phi index and PCA3 score allowed to reach an overall diagnostic accuracy of 0.77. Decision curve analysis revealed that this "combined" marker achieved the highest net benefit over the examined range of the threshold probability. CONCLUSIONS phi and PCA3 showed no significant difference in the ability to predict PCa diagnosis in men undergoing first prostate biopsy. However, diagnostic performance is significantly improved by combining phi and PCA3.

Abstract
Indication for prostate biopsy is presently mainly based on prostate-specific antigen (PSA) serum levels and digital-rectal examination (DRE). In view of the unsatisfactory accuracy of these two diagnostic exams, research has focused on novel markers to improve pre-biopsy prostate cancer detection, such as phi and PCA3. The purpose of this prospective study was to assess the diagnostic accuracy of phi and PCA3 for prostate cancer using biopsy as gold standard. Phi index (Beckman coulter immunoassay), PCA3 score (Progensa PCA3 assay) and other established biomarkers (tPSA, fPSA and %fPSA) were assessed before a 18-core prostate biopsy in a group of 251 subjects at their first biopsy. Values of %p2PSA and phi were significantly higher in patients with PCa compared with PCa-negative group (p<0.001) and also compared with high grade prostatic intraepithelial neoplasia (HGPIN) (p<0.001). PCA3 score values were significantly higher in PCa compared with PCa-negative subjects (p<0.001) and in HGPIN vs PCa-negative patients (p<0.001). ROC curve analysis showed that %p2PSA, phi and PCA3 are predictive of malignancy. In conclusion, %p2PSA, phi and PCA3 may predict a diagnosis of PCa in men undergoing their first prostate biopsy. PCA3 score is more useful in discriminating between HGPIN and non-cancer.

Abstract
BACKGROUND About 43% of men with low Gleason grade prostate cancer (PCa) at biopsy will be finally diagnosed with high-grade PCa at radical prostatectomy (RP). Gleason sum at RP is a good indicator of biochemical recurrence and poor clinical outcome. Therefore, there is a need to improve clinical evaluation of PCa aggressiveness in order to choice appropriate treatment. To this aim an easy-available tool is represented by circulating biomarkers. Among these, the best candidates are some molecules involved in PCa pathogenesis such as IGFBP-2 and IGFBP-3, IL-6, and its soluble receptor (SIL-6R). METHODS In this study, we evaluated the ability of preoperative IGFBP-2, IGFBP-3, IL-6, and SIL-6R serum levels to predict Gleason score upgrade in 52 PCa patients. RESULTS We found that IGFBP-3 median levels were significantly lower in patients who showed Gleason upgrading from biopsy to RP (P = 0.024). We also found an association between biopsy T-stage and Gleason Upgrade (P = 0.011). Using multivariate logistic regression model, we demonstrated that the association of IGFBP-3 serum levels together with biopsy T-stage and biopsy Gleason score was useful to calculate a prognostic risk score. ROC curve analysis of risk score showed a good ability to predict GSU (AUC = 0.81; 95% CI 0.69-0.93). CONCLUSIONS Our results suggest that preoperative IGFBP-3 circulating levels determination may be useful to predict Gleason score upgrading alone and/or in combination with biopsy T-stage and biopsy Gleason score.

Abstract
BACKGROUND Alpha-enolase is a glycolytic enzyme that catalyses the formation of phosphoenolpyruvate in the cell cytoplasm. α-Enolase and the predominantly nuclear Myc promoter-binding protein-1 (MBP-1) originate from a single gene through the alternative use of translational starting sites. MBP-1 binds to the P2 c-myc promoter and competes with TATA-box binding protein (TBP) to suppress gene transcription. Although several studies have shown an antiproliferative effect of MBP-1 overexpression on several human cancer cells, to date detailed observations of α-enolase and MBP-1 relative expression in primary tumors versus normal tissues and their correlation with clinicopathological features have not been undertaken. METHODOLOGY AND FINDINGS We analyzed α-enolase and MBP-1 expression in normal breast epithelium and primary invasive ductal breast carcinoma (IDC) from 177 patients by Western blot and immunohistochemical analyses, using highly specific anti-α-enolase monoclonal antibodies. A significant increase in the expression of cytoplasmic α-enolase was observed in 98% of the tumors analysed, compared to normal tissues. Nuclear MBP-1 was found in almost all the normal tissues while its expression was retained in only 35% of the tumors. Statistically significant associations were observed among the nuclear expression of MBP-1 and ErbB2 status, Ki-67 expression, node status and tumor grade. Furthermore MBP-1 expression was associated with good survival of patients with IDC. CONCLUSIONS MBP-1 functions in repressing c-myc gene expression and the results presented indicate that the loss of nuclear MBP-1 expression in a large number of IDC may be a critical step in the development and progression of breast cancer and a predictor of adverse outcome. Nuclear MBP-1 appears to be a novel and valuable histochemical marker with potential prognostic value in breast cancer.

Abstract
Prostate cancer is one of the most frequently diagnosed cancer in men. Treatment by radical prostatectomy, radiotherapy and anti-androgen drugs is successful in patients with localized cancer. However, prolonged androgen deprivation often leads to hormone refractory condition, associated with disease relapse. ErbB1 and ErbB2 activity has been correlated with androgen-independence. We determined the effects of GW2974, a dual inhibitor of ErbB-1 and ErbB-2 tyrosine kinase activity, on growth, NSE, chromogranin A and osteopontin cytosol content in the androgen-independent prostate cancer cell line PC-3. We found that PC-3 cell growth was inhibited by GW2974, whereas NSE and chromogranin A cell contents were stimulated and osteopontin cytosol level was not affected. The present data may have clinical implications for the treatment of advanced prostate cancer.

Abstract
A panel of tumour markers including carcinoembryonic antigen (CEA), carbohydrate antigen (Ca)15-3, Ca125 and Ca19-9 were measured in the lysate of sediments and in the supernatants of pleural effusions of patients with benign and malignant disease. The tumour markers were also measured in the serum of the same patients. Of these patients, 32 had benign diseases (12 trasudative effusions associated with cirrhosis and 20 with non-malignant exudates: 12 pleuritis and 8 other inflammations) and 103 had malignant effusions (37 breast cancers, 29 lung cancers, 10 ovary cancers, 6 kidney cancers, 11 mesotheliomas and 10 lymphomas). We showed the highest level of CEA in pleural effusions of lung cancer followed by that in pleural effusions of breast cancer; whereas Ca15-3 was very high in the pleural effusions of breast and lung cancer. Concerning the lysate of sediment, CEA was high in the pleural effusions of patients with lung cancer and Ca15-3 in those of patients with breast cancer. The other markers are much less useful. For the remaining tumours, none of the markers tested appear to aid in the diagnosis of disease. In conclusion, our data suggest that the combined determination of tumour markers on supernatants and sediments of pleural effusion may provide additional information on the nature of pleural effusion, especially for cases with negative cytology.

Abstract
Background: Tissue Polypeptide Specific antigen has recently been proposed as diagnostic marker of apoptosis in NonAlcoholic SteatoHepatitis. The aim of this study was to validate in patients suffering from NonAlcoholic SteatoHepatitis the clinical utility of this marker after different programs of weight reduction. Methods: Overweight/obese patients with visceral adiposity and liver histology compatible were assigned to a Calorically-Restricted diet (n = 22), a Calorically-Restricted diet plus EXercise (n = 19) or No Healthy Life Style (control group, n = 21) for six months. The presence of Body-Weight loss was assessed by a Body Mass Index decrease of at least three points. Serum ALanine aminoTransferase, HOmeostasis Model Assessment method value and Tissue Polypeptide Specific antigen concentrations were determined at time 0, after 3 and 6 months in both the Intervention groups and in the controls’ one. Results: In NonAlcoholic SteatoHepatitis patients who obtained Body-Weight reduction, a significant decrease of the serum Tissue Polypeptide Specific antigen values was showed with a clear linear trend across time, P = 0.0001. Decrement of Tissue Polypeptide Specific antigen concentrations best differentiated the Body-Weight loss from the body-weight maintenance in respect to Tissue Polypeptide Specific antigen and HOmeostasis Model Assessment method values. Conclusion: This study support the clinical utility of serum Tissue Polypeptide Specific antigen antigen levels in the follow-up of overweight/obese patients with NonAlcoholic SteatoHepatitis on weight reduction programs.

Abstract
CONTEXT The cardiovascular consequences of thyroid diseases are attributed to the altered secretion of thyroid hormones. The possibility that TSH also affects the cardiovascular system has been poorly explored. Endothelial cells and vascular smooth muscle cells possess TSH receptors. OBJECTIVE The study was designed to determine whether TSH exerts any effect on vascular homeostasis. SUBJECTS AND METHODS Two different double-blind, controlled studies were performed, one in eight healthy volunteers and the other in six thyroidectomized patients. Recombinant human (rh) TSH (or saline) was infused intrabrachially (1 mU/min) to raise TSH to severe hypothyroidism levels (approximately 100 microU/ml). Endothelium-dependent and -independent vasodilation was tested by intraarterial infusion of acetylcholine and sodium nitroprusside, respectively, and forearm blood flow was measured by plethysmography. RESULTS Endothelium-dependent vasodilation was potentiated by rhTSH (P < 0.05 for the treatment effect; general linear model). The dynamics of the response was also profoundly affected by rhTSH because the dose-response curve was much steeper than in controls (P < 0.02 for the interaction between TSH and acetylcholine). rhTSH had no effect on endothelium-independent vasodilation (P = NS for both treatment and interaction). During rhTSH infusion, free T(3) levels increased slowly from 2.3 +/- 0.2 to 3.6 +/- 0.2 pg/ml. In thyroidectomized patients, rhTSH potentiated endothelium-mediated vasodilation to an extent similar to that of healthy subjects (P = 0.05 for the treatment effect and P = 0.01 for the interaction), without affecting the response to nitroprusside. In these patients, thyroid hormones remained unchanged during rhTSH infusion. CONCLUSIONS rhTSH exerts marked effects on the resistance vessels by enhancing endothelial-mediated vasodilation, independent of changes in thyroid hormone concentration.

Abstract
PURPOSE To examine differences in peripheral vascular endothelial growth factor (VEGF), interleukin-6 (IL6) and cortisol concentrations between patients with both visceral obesity and metabolic syndrome, and lean controls. In a subsample of metabolic patients underwent abdominal surgery, the adipokine concentrations were measured in venous blood from the omentum to determine information on some processes of synthesis. METHODS Forty-two healthy lean controls and 46 overweight-obese patients with central adiposity and stigmata of metabolic syndrome were studied. In a subsample of 11 metabolic patients undergoing non-bariatric surgery, blood samples from omental and peripheral veins were taken intraoperatively to determine VEGF, IL6 and cortisol concentrations. RESULTS Median levels (range) of peripheral VEGF and IL6 were higher in patients than in controls [31.5 (3-112) pg/mL vs 21.35 (9-41.9) pg/mL (P < 0.05) and 5.50 (1.40-13) pg/mL vs 1.15 (0.3-1) pg/mL (P < 0.0001)]. On the other hand, concentrations of VEGF and IL6 from the omental and peripheral veins were similar in the surgery sub-group. Peripheral cortisol concentrations were not higher in patients than in controls, nor were omental concentrations different from the peripheral. Omental and peripheral VEGF and cortisol values were correlated, whereas no association was found between omental and peripheral IL6. CONCLUSIONS In the presence of abdominal obesity, VEGF and IL6 concentrations are increased in the systemic circulation. The contribution of visceral adipose tissue to circulating levels of VEGF and IL6 was modest.

Abstract
Matrix metalloproteinases (MMPs) are proteolytic enzymes that are implicated in multiple stages of cancer progression including invasion and metastasis. MMPs exert these effects by cleaving a diverse group of substrates, which include not only structural components of the extracellular matrix, but also growth factor receptors. By gelatin zymography we verified MMP activity in the pleural effusions of patients with benign and malignant disease. Of these patients, 32 had malignant pleural effusion, consisting of 20 breast cancer, 6 non-small cell lung carcinoma, 4 ovarian carcinoma, and 2 colonic adenocarcinoma, and 10 had benign pleural effusion (5 pleurisy and 5 cirrhosis). Zymography showed the constant presence of a substantial amount of MMP-2 in all samples analyzed, whereas MMP-9 was present to lesser quantities. MMP-2 activity was enhanced in pleural effusions from patients with benign diseases compared with cancer patients. MMP-9 was present in 59% of cancer patients and the lytic activity was enhanced in pleurisy and absent in cirrhosis. Furthermore, we determined the pleural effusion levels of the soluble extracellular domain of HER-2/neu. The levels of HER-2/neu ECD were above the cut-off value in breast cancer patients. No correlation between gelatinolytic activities and high HER-2/neu ECD values was found.

Abstract
The authors report their experience with a case of a voluminous malignant pleomorphic histiocytoma of the anterior abdominal wall occurring in an 81-year-old female patient. She presented with a one-year history of a non-painful, poorly mobile tumefaction which had grown in size over the 2 months prior to admission. A preoperative CT scan confirmed the presence of a 10-cm mass located in the anterior abdominal wall. The patient underwent resection of the tumour and was discharged on postoperative day 15. A 12-month follow-up has so far revealed no evidence of recurrence. The authors go on to examine the diagnostic and therapeutic treatments of these rare neoplasms with reference to the international scientific literature. They confirm the validity of radiotherapy but stress the elective role of surgical treatment.

Abstract
FRT thyroid epithelial cells synthesize fibronectin and organize a network of fibronectin fibrils at the basal surface of the cells. Fibronectin fibril formation is enhanced by the overexpression of the ubiquitous beta1A integrin and is inhibited by the expression of the dominant-negative beta1B subunit. We tested the hypotheses that RhoA activity might mediate the integrin-dependent fibronectin fibrillogenesis and might counteract beta1B integrin inhibitory effect. FRT-beta1A cells were transfected with a vector carrying a dominant negative form of RhoA (RhoAN19) or treated with the C3 transferase exoenzyme. Both treatments inhibited fibronectin assembly and caused loss of actin microfilaments and adhesion plaques. On the other hand, FRT-beta1B cells were transfected with the constitutively activated form of RhoA (RhoAV14) or treated with the E. coli cytotoxic necrotizing factor 1, which directly activates RhoA. Either treatment restored microfilament and adhesion plaque assembly and promoted fibronectin fibril organization. A great increase in fibronectin fibril assembly was also obtained by treatment of FRT-beta1B cells with TGF-beta. Our data indicate that RhoA is required to promote fibronectin matrix assembly in FRT cells and that the activation of the signal transduction pathway downstream of RhoA can overcome the inhibitory effect of beta1B integrin.
