Abstract
β-Nitrocorroles are potentially valuable platforms for the preparation of a wide range of more elaborated corrole derivatives possessing unique chemical functionalities and electronic properties. Here we report our results on the chemical manipulation of a copper 3-NO2-triarylcorrolate using different organic reactions, all involving the reduction of -NO2 to -NH2 at an early stage, followed by further transformations. By way of a β-acylated copper corrolate, a novel corrole derivative bearing an alkyl azide group on the peripheral positions was obtained and exploited in the Huisgen 1,3-dipolar cycloaddition.

Abstract
OBJECTIVES Galectin-3 (Gal-3) testing is emerging as a valuable tool for the prognosis of heart failure (HF). Our objectives were to determine the clinical validity and cost-effectiveness of the recently developed ARCHITECT Gal-3 automated immunoassay. DESIGN AND METHODS Gal-3 levels were measured in HF patients with reduced left ventricular ejection fraction with the ARCHITECT i2000SR Gal-3 assay as well as with the reference Gal-3 ELISA assay. The relationship between Gal-3 levels determined with the automated assay and HF severity as well as its predictive value for long-term cardiovascular death were evaluated. The impact of Gal-3 testing on the diagnostic related group (DRG) based reimbursement was also estimated. RESULTS Gal-3 levels measured with the ARCHITECT assay were related to the severity of HF based on New York Heart Association functional classes (p<0.001) and were also significantly and positively correlated to BNP concentrations (r=0.35, p<0.001). Gal-3 values higher than 19.2 ng/mL were predictive of long-term cardiovascular death in patients with systolic HF and also provided incremental prognostic information to BNP testing. In addition, Gal-3 testing was estimated to save DRG in comparison to standard of care. CONCLUSIONS Our results demonstrated the clinical validity of the ARCHITECT Gal-3 automated immunoassay for the risk stratification of HF patients. The automation of Gal-3 testing was also cost-effective and might help to preserve hospital budget.

Br J Cancer 2014; 110:2865-73. [PMID: 24853185 PMCID: PMC4056066 DOI: 10.1038/bjc.2014.269] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2014] [Revised: 04/15/2014] [Accepted: 04/23/2014] [Indexed: 12/31/2022] Open
Abstract
Background: Metastatic triple-negative breast cancer is mostly incurable, due to lack of suitable drug targets. The insulin-like growth factor (IGF) system could provide such a target, and IGF-1 receptor (IGF-1R)-directed agents are already available, but seem unable to control all the complexities of the system, including crosstalk with hypoxia-inducible pathways. Methods: Migration of triple-negative MDA-231 breast cancer cells and its modulation by IGFs, the IGF-1R inhibitor NVP-AEW541 and the IGF-2-sequestering monoclonal antibody MAB292 were assessed by the scratch wound healing and Boyden chamber assays; the effect of topotecan (inhibiting hypoxia-inducible factor-1 (HIF-1)) under hypoxia was also evaluated. Constitutive as well as drug-modulated levels of components of the IGF and HIF-1 pathways were evaluated by western blotting and qPCR. Results: IGF-induced migration of MDA-231 cells was not abrogated by the IGF-1R inhibitor NVP-AEW541, whereas IGF-2 sequestration by MAB292 significantly reduced cell migration. Under hypoxia, topotecan was also effective, likely by reducing HIF-1-induced IGF-2 release. Simultaneous targeting of IGF-1R and IGF-2 or HIF-1 completely abolished cell migration. Conclusions: IR activation may account for the failure of NVP-AEW541 to suppress MDA-231 cell migration. Ligand-targeting compounds, or co-inhibition of the IGF and HIF-1 systems, may prevent activation of compensatory signalling, thereby providing a valuable addition to IGF-1R inhibitor-based therapies.

Abstract
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare disease of controversial origin recently recognized as a neoplasm deriving from plasmacytoid dendritic cells (pDCs). Nevertheless, it remains an orphan tumor with obscure biology and dismal prognosis. To better understand the pathobiology of BPDCN and discover new targets for effective therapies, the gene expression profile (GEP) of 25 BPDCN samples was analyzed and compared with that of pDCs, their postulated normal counterpart. Validation was performed by immunohistochemistry (IHC), whereas functional experiments were carried out ex vivo. For the first time at the molecular level, we definitely recognized the cellular derivation of BPDCN that proved to originate from the myeloid lineage and in particular, from resting pDCs. Furthermore, thanks to an integrated bioinformatic approach we discovered aberrant activation of the NF-kB pathway and suggested it as a novel therapeutic target. We tested the efficacy of anti-NF-kB-treatment on the BPDCN cell line CAL-1, and successfully demonstrated by GEP and IHC the molecular shutoff of the NF-kB pathway. In conclusion, we identified a molecular signature representative of the transcriptional abnormalities of BPDCN and developed a cellular model proposing a novel therapeutic approach in the setting of this otherwise incurable disease.

Abstract
Heat shock protein 90 (HSP90) is a molecular chaperone that regulates critical signalling proteins of cancer development and progression. Abnormal levels of HSP90 have been observed in human prostatic carcinoma (PC), with prognostic and therapeutic implications. Since spontaneously arising canine PC is a valuable model for the human disease, the aim of this study was to evaluate the immunohistochemical expression of HSP90 in two normal canine prostates, 17 canine prostates with benign prostatic hyperplasia (BPH) and five canine prostates with PC. HSP90 was expressed in the cytoplasm of epithelial cells in all samples, with a significant increase in labelled cells in PCs. Nuclear labelling was observed occasionally in normal tissue, but was increased in BPH and PC. HSP90 immunoreactivity in preneoplastic lesions (proliferative inflammatory atrophy and prostatic intraepithelial neoplasia) was similar to that in PCs. Increased HSP90 expression in canine PCs suggests the involvement of this molecule in carcinogenesis and tumour progression, supporting HSP90 as a potential target for therapeutic intervention.

Abstract
Background Ultrasound is a valuable non-invasive tool used in obstetrics and gynecology to monitor the growth and well being of the human fetus. The laboratory mouse has recently emerged as an appropriate model for fetal and perinatal studies because morphogenetic processes in mice exhibit adequate homology to those in humans, and genetic manipulations are relatively simple to perform in mice. High-frequency ultrasound (HFUS) has recently become available for small animal preclinical imaging and can be used to study pregnancy and development in the mouse. The objective of the current study was to assess the main applications of HFUS in the evaluation of fetal growth and placental function and to better understand human congenital diseases. Methodology/Principal Findings On each gestational day, at least 5 dams were monitored with HFUS; a total of ∼200 embryos were examined. Because it is not possible to measure each variable for the entire duration of the pregnancy, the parameters were divided into three groups as a function of the time at which they were measured. Univariate analysis of the relationship between each measurement and the embryonic day was performed using Spearman’s rank correlation (Rs). Continuous linear regression was adopted for multivariate analysis of significant parameters. All statistical tests were two-sided, and a p value of 0.05 was considered statistically significant. Conclusions/Significance The study describes the main applications of HFUS to assess changes in phenotypic parameters in the developing CD1 mouse embryo and fetus during pregnancy and to evaluating physiological fetal and placental growth and the development of principal organs such as the heart, kidney, liver, brain and eyes in the embryonic mouse. A database of normal structural and functional parameters of mouse development will provide a useful tool for the better understanding of morphogenetic and cardiovascular anomalies in transgenic and mutant mouse models.

Abstract
BACKGROUND To evaluate whether Contrast Enhanced Ultrasund (CEUS) with microbubbles (MBs) targeted to VEGFR-2 is able to characterize in vivo the VEGFR-2 expression in the tumor vasculature of a mouse model of thyroid cancer (Tg-TRK-T1). METHODS Animal protocol was approved by Institutional committee on Laboratory Animal Care. Contrast-enhanced ultrasound imaging with MBs targeted with an anti-VEGFR-2 monoclonal antibody (UCAVEGFR-2) and isotype control antibody (UCAIgG) was performed in 7 mice with thyroid carcinoma, 5 mice with hyperplasia or benign thyroid nodules and 4 mice with normal thyroid. After ultrasonography, the tumor samples were harvested for histological examination and VEGFR-2 expression was tested by immunohistochemistry. Data were reported as median and range. Paired non parametric Wilcoxon's test and ANOVA of Kruskal-Wallis were used. The correlation between the contrast signal and the VEGFR-2 expression was assessed by the Spearman coefficient. RESULTS The Video intensity difference (VID) caused by backscatter of the retained UCAVEGFR-2 was significantly higher in mice harboring thyroid tumors compared to mice with normal thyroids (P < 0.01) and to mice harboring benign nodules (P < 0.01). No statistically significant differences of VID were observed in the group of mice carrying benign nodules compared to mice with normal thyroids. Moreover in thyroid tumors VID of retained VEGFR-2-targeted UCA was significantly higher than that of control UCAIgG (P <0.05). Results of immunohistochemical analysis confirmed VEGFR-2 overexpression. The magnitude of the molecular ultrasonographic signal from a VEGFR-2-targeted UCA retained by tissue correlates with VEGFR-2 expression determined by immunohistochemistry (rho 0.793, P=0.0003). CONCLUSIONS We demonstrated that CEUS with UCAVEGFR-2 might be used for in vivo non invasive detection and quantification of VEGFR-2 expression in thyroid cancer in mice, and to differentiate benign from malignant thyroid nodules.

Abstract
OBJECTIVES The purpose of this study was to evaluate the renal volume and intrarenal hemodynamics with duplex sonography in a group of diabetic patients with normal renal function in comparison to nondiabetic controls. METHODS The renal volume and resistive index (RI) of segmental arteries were assessed by duplex sonography in 88 diabetic patients (44 male and 44 female; median age, 58 years [range, 37-69 years]) and 73 nondiabetic control participants (48 male and 25 female; median age, 53 years [range, 27-75 years]) without renal artery stenosis. RESULTS Both renal volume and RI values in the diabetic patients were significantly higher compared to the controls (mean volume ± SD: diabetic patients, 197.3 ± 47.6 mL; controls, 162.5 ± 35.2 mL; P < .0001; RI: diabetic patients, 0.70 ± 0.05; controls, 0.59 ± 0.06; P < .0001). Renal hypertrophy was present even in diabetic patients without proteinuria (renal volume: patients without proteinuria, 198.3 ± 45.9 mL; controls, 162.5 ± 35.2 mL; P < .005). Patients with higher RI values had significantly greater proteinuria (RI <0.75, 15.9 mg/g [range, 4.2-1718.9 mg/g]; RI >0.75, 37.9 mg/g [range, 11.34-2087.0 mg/g]; P < .02). CONCLUSIONS Changes in renal volume and hemodynamics are detectable on sonography in diabetic patients. Those changes are also present in patients without proteinuria or signs of renal atherosclerosis and with both normal and increased glomerular filtration rates. These results indicate a potential role of duplex sonography in the early identification of morphologic and hemodynamic renal changes in type 2 diabetic patients.

Abstract
Background This study aimed to investigate the prevalence and clinical relevance of chronic cerebrospinal venous insufficiency (CCSVI) in multiple sclerosis (MS) patients and healthy controls using extra- and intracranial colour Doppler sonography. Methods We examined 146 MS patients, presenting with a clinically isolated syndrome, relapsing-remitting, secondary progressive, or primary progressive MS, and 38 healthy controls. Sonographic examination was performed according to Zamboni’s protocol and was performed by three independent sonographers. The results of sonographic examination were compared with clinical and demographic characteristics of the patients. Results CCSVI, defined as the presence of at least two positive Zamboni’s criteria, was found in 76% of MS patients and 16% of control subjects. B-mode anomalies of internal jugular veins, such as stenosis, malformed valves, annuli, and septa were the most common lesions detected in MS patients (80.8%) and controls (47.4%). We observed a positive correlation between sonographic diagnosis of CCSVI and the patients’ age (p = 0.003). However, such a correlation was not found in controls (p = 0.635). Notably, no significant correlations were found between sonographic signs of CCSVI and clinical characteristics of MS, except for absent flow in the jugular veins, which was found more often in primary (p<0.005) and secondary (p<0.05) progressive patients compared with non-progressive patients. Absent flow in jugular veins was significantly correlated with patients’ age (p < 0.0001). Conclusions Sonographically defined CCSVI is common in MS patients. However, CCSVI appears to be primarily associated with the patient’s age, and poorly correlated with the clinical course of the disease.

Abstract
BACKGROUND Preclinical perfusion studies are useful for the improvement of diagnosis and therapy in dermatologic, cardiovascular and rheumatic human diseases. The Laser Doppler Perfusion Imaging (LDPI) technique has been used to evaluate superficial alterations of the skin microcirculation in surgically induced murine hindlimb ischemia. We assessed the reproducibility and the accuracy of LDPI acquisitions and identified several critical factors that could affect LDPI measurements in mice. METHODS Twenty mice were analysed. Statistical standardisation and a repeatability and reproducibility analysis were performed on mouse perfusion signals with respect to differences in body temperature, the presence or absence of hair, the type of anaesthesia used for LDPI measurements and the position of the mouse body. RESULTS We found excellent correlations among measurements made by the same operator (i.e., repeatability) under the same experimental conditions and by two different operators (i.e., reproducibility). A Bland-Altman analysis showed the absence of bias in repeatability (p = 0.29) or reproducibility (p = 0.89). The limits of agreement for repeatability were -0.357 and -0.033, and for reproducibility, they were -0.270 and 0.238. Significant differences in perfusion values were observed in different experimental groups. CONCLUSIONS Different experimental conditions must be considered as a starting point for the evaluation of new drugs and strategic therapies.

Abstract
Despite optimal treatment (complete cytoreduction and adjuvant chemotherapy), 5-year survival for advanced ovarian cancer is approximately 30% and most patients succumb to their disease. Cytoreductive surgery is accepted as a major treatment of primary ovarian cancer but its role in recurrent disease is controversial and remains a field of discussion mainly owing to missing data from prospective randomized trials. A critical review of literature evidence on secondary surgery in recurrent ovarian cancer will be described.

Abstract
OBJECTIVE To evaluate the effects of qualitative dietary changes and the interaction with aerobic exercise training on liver fat content independent of weight loss in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS With use of a factorial 2 × 2 randomized parallel-group design, 37 men and 8 women, aged 35-70 years, with type 2 diabetes in satisfactory blood glucose control on diet or diet plus metformin treatment were assigned to one of the following groups for an 8-week period: 1) high-carbohydrate/high-fiber/low-glycemic index diet (CHO/fiber group), 2) high-MUFA diet (MUFA group), 3) high-carbohydrate/high-fiber/low-glycemic index diet plus physical activity program (CHO/fiber+Ex group), and 4) high-MUFA diet plus physical activity program (MUFA+Ex group). Before and after intervention, hepatic fat content was measured by (1)H NMR. RESULTS Dietary compliance was optimal and body weight remained stable in all groups. Liver fat content decreased more in MUFA (-29%) and MUFA+Ex (-25%) groups than in CHO/fiber (-4%) and CHO/fiber+Ex groups (-6%). Two-way repeated-measures ANOVA, including baseline values as covariate, showed a significant effect on liver fat content for diet (P = 0.006), with no effects for exercise training (P = 0.789) or diet-exercise interaction (P = 0.712). CONCLUSIONS An isocaloric diet enriched in MUFA compared with a diet higher in carbohydrate and fiber was associated with a clinically relevant reduction of hepatic fat content in type 2 diabetic patients independent of an aerobic training program and should be considered for the nutritional management of hepatic steatosis in people with type 2 diabetes.

Abstract
Keratinocyte replicative senescence has an important role in time-dependent changes of the epidermis, a tissue with high turnover. Senescence encompasses growth arrest during which cells remain metabolically active but acquire a typical enlarged, vacuolar and flattened morphology. It is also accompanied by the expression of endogenous senescence-associated-β-galactosidase and specific gene expression profiles. MicroRNAs levels have been shown to be modulated during keratinocytes senescence, playing key roles in inhibiting proliferation and in the acquisition of senescent markers. Here, we identify miR-191 as an anti-proliferative and replicative senescence-associated miRNA in primary human keratinocytes. Its overexpression is sufficient per se to induce senescence, as evaluated by induction of several senescence-associated markers. We show that SATB1 and CDK6 3′UTRs are two miR-191 direct targets involved in this pathway. Cdk6 and Satb1 protein levels decrease during keratinocytes replicative senescence and their silencing by siRNA is able to induce a G1 block in cell cycle, accompanied by an increase in senescence-associated markers.

Abstract
We report a rare case of a 50 year old man with renal squamous cell carcinoma (SCC) who first came to our attention with renal colic and fever not responding to antibiotic or analgesic treatment. He had a long history of kidney stones, but had not undergone any imaging in the last 5 years. Physical examination revealed tenderness and a palpable mass in the right flank and lumbar region. A whole body CT scan was performed, revealing an 11 cm mass in the right kidney infiltrating the inferior vena cava. There were areas of calcification within the mass and multiple stones within the renal pelvis. The tumor was considered unsuitable for resection according to radiological and clinical criteria. The mass was biopsied percutaneously under CT guidance and histological examination revealed squamous cell carcinoma of the renal pelvis. The patient was treated with neoadjuvant chemotherapy and embolization of the renal artery. He died one month after diagnosis. To our knowledge this is the second reported case in the world of renal SCC infiltrating the inferior vena cava and with kidney stones.

Abstract
While balance and gait limitations are hallmarks of multiple sclerosis (MS), standard stopwatch-timed measures practical for use in the clinic are insensitive in minimally affected patients. This prevents early detection and intervention for mobility problems. The study sought to determine if body-worn sensors could detect differences in balance and gait between people with MS with normal walking speeds and healthy controls. Thirty-one MS and twenty-eight age- and sex-matched control subjects were tested using body-worn sensors both during quiet stance and gait (Timed Up and Go test, TUG). Results were compared to stopwatch-timed measures. Stopwatch durations of the TUG and Timed 25 Foot Walk tests were not significantly different between groups. However, during quiet stance with eyes closed, people with MS had significantly greater sway acceleration amplitude than controls (p=0.02). During gait, people with MS had greater trunk angular range of motion in roll (medio-lateral flexion, p=0.017) and yaw (axial rotation, p=0.026) planes. Turning duration through 180° was also longer in MS (p=0.031). Thus, body-worn motion sensors detected mobility differences between MS and healthy controls when traditional timed tests could not. This portable technology provides objective and quantitative mobility data previously not obtainable in the clinic, and may prove a useful outcome measure for early mobility changes in MS.

Abstract
Abstract
BACKGROUND: Among the different chemotherapeutic options available for adjuvant treatment of early breast cancer (EBC), anthracycline-containing regimens represent prevalent choices. OSCAR/ABC is an observational, prospectic, multicentric study aimed at evaluating, in the clinical practice, the relevance of cardiac dysfunction and congestive heart failure (CHF) associated to “free choice”, anthracycline-containing adjuvant regimens and to identify patients at increased cardiac risk. PATIENTS AND METHODS: patients candidate to receive adjuvant anthracycline-containing chemotherapy, will be enrolled in the study. Data on demographic and clinical characteristics of patients (age, cardio-vascular comorbidity) tumor features (TNM, histotype, ER and PgR status, Ki67, and HER2 status), type of adjuvant regimen and tolerability of treatment will be collected and centrally registered at the Consorzio Interuniversitario Nazionale per ***1a Bio-Oncologia (CINBO) using e-CRFs. Data on type, sites and doses of radiotherapy performed will be collected, to evaluate the possible impact on cardiac function. Primary aim of the study is to evaluate the prevalence of cardiac dysfunction and CHF among the whole population enrolled, particularly according to risk criteria and type of administered chemotherapy. Cardiac dysfunction is defined as limiting cardio-vascular toxicity (≥ Grade 3 dyspnea, arrhytmia, hypertension) and/or asymptomatic LVEF reduction ≥20% (if >50% at the baseline) or ≥10% (if ≤50% at baseline); CHF is defined as clinical diagnosis and/or symptomatic LVEF reduction ≥20% (if >50% at the baseline) or ≥10% (if ≤50% at baseline). Assessment of cardiac risk involves the evaluation of age (< vs ≥ 65 years), cardio-vascular comorbidities (requiring treatment or not) and Left-Ventricular Ejection Fraction LVEF (> vs ≤ 55%) at diagnosis. Clinical and instrumental cardiac evaluation (ECG, Ecocardiography) will be performed at study entry, on-treatment and up to 5 years thereafter. Secondary objective of the study is to evaluate the clinical properness of different adjuvant anthracyclines-containing chemotherapy options, with regard to prevalence of therapeutic regimens, safety, efficacy (DFS and OS) and costs analysis. Cardiac safety and general toxicity on-treatment will be evaluated according to NCI criteria. The expected enrollment is 1,200 patients in 36 months. From September 2010 to May 2011, 7 of the 13 Centers involved in the study are active, with 65 enrolled patients.

Abstract
BACKGROUND Obesity is associated with a systemic, low-grade inflammatory state. Although the relationship between obesity and semen parameters or prostate diseases has been previously investigated, the association between body mass index (BMI), prostate inflammatory diseases and color- Doppler ultrasound (CDU) of the male genital tract (MGT) has been poorly studied. AIM To evaluate the association between BMI and CDU features of the MGT, signs and symptoms of prostate inflammation, semen parameters. MATERIALS/SUBJECTS AND METHODS We studied 222 men seeking medical care for couple infertility. According to the World Health Organization classification, subjects were divided into 3 groups: normal weight (no.=131, BMI=18.5-24.9 kg/m2), overweight (no.=71, BMI=25.0-29.9 kg/m2), obese (no.=20, BMI≥30.0 kg/m2). All patients underwent simultaneous testosterone evaluation and seminal analysis, including interleukin 8 (sIL-8), along with scrotal and transrectal CDU, before and after ejaculation. Prostatitis symptoms were evaluated by National Institutes of Health- Chronic Prostatitis Symptom Index questionnaire. RESULTS After adjusting for age and testosterone levels, higher BMI was significantly related to higher prostate volume and several CDU features of the prostate, including macro-calcifications, inhomogeneity, higher arterial peak systolic velocity (the latter adjusted also for blood pressure), but not with abnormalities of testis, epididymis, seminal vesicles. Furthermore, higher BMI and BMI class were significantly related to higher sIL-8, a reliable surrogate marker of prostate inflammatory diseases, even after adjustment for age. Conversely, no associations among BMI, clinical symptoms of prostatitis or semen parameters were observed. CONCLUSIONS Subjects with higher BMI might develop CDU and biochemical signs suggestive of prostate inflammation, although not clinically overt.

Abstract
BACKGROUND Chronic cerebrospinal venous insufficiency (CCSVI) has recently been reported to be associated with multiple sclerosis (MS). However, its actual prevalence, possible association with specific MS phenotypes, and potential pathophysiological role are debated. METHOD We analysed the clinical data of 710 MS patients attending six centres (five Italian and one Canadian). All were submitted to venous Doppler sonography and diagnosed as having or not having CCSVI according to the criteria of Zamboni et al. RESULTS Overall, CCSVI was diagnosed in 86% of the patients, but the frequency varied greatly between the centres. Even greater differences were found when considering singly the five diagnostic criteria proposed by Zamboni et al. Despite these differences, significant associations with clinical data were found, the most striking being age at disease onset (about five years greater in CCSVI-positive patients) and clinical severity (mean EDSS score about one point higher in CCSVI-positive patients). Patients with progressive MS were more likely to have CCSVI than those with relapsing-remitting MS. CONCLUSION The methods for diagnosing CCSVI need to be refined, as the between-centre differences, particularly in single criteria, were excessively high. Despite these discrepancies, the strong associations between CCSVI and MS phenotype suggest that the presence of CCSVI may favour a later development of MS in patients with a lower susceptibility to autoimmune diseases and may increase its severity.

Abstract
PURPOSE The aim of this study was to explore the diagnostic performance of multidetector computed tomography (MDCT) in characterising pancreatic metastases. MATERIALS AND METHODS CT examinations of 17 patients affected by pancreatic metastases were retrospectively reviewed. The primary malignancy was renal cell carcinoma (RCC) in eight cases, uterine leiomyosarcoma in two, lung carcinoma in four and breast carcinoma in three. CT images were assessed for lesion number, size and morphology. RESULTS Pancreatic lesions were solitary in seven cases and multiple in ten. Lesion size ranged between 8 and 40 mm. Metastases from RCC were hyperattenuating in the arterial phase, metastases from breast cancer and lung cancer were hypoattenuating and metastases from uterine leiomyosarcoma were inhomogeneous. Precise lesion characterisation was obtained by using CT examination in 12 cases. In the remaining five patients, all with solitary metastases from RCC, a precise diagnosis was not possible because the lesions could not be differentiated from a neuroendocrine tumour. CONCLUSIONS MDCT allowed pancreatic metastases characterisation in 70.5% of cases. The lesions were the manifestation of widely disseminated neoplastic disease, with the exception of metastases from RCC, which were exclusively located in the pancreas.

Abstract
BACKGROUND AND AIMS Metabolic syndrome (MS) has recently been claimed to be an important new risk factor for the occurrence of coronary heart disease (CHD) and cardiovascular disease (CVD) events, although it is simply a combination of known risk factors used in a dichotomized fashion. The aims of this analysis were to explore the predictive role of MS for CHD and CVD events in a population study, in comparison with using the same factors in a continuous fashion, with special emphasis on HDL cholesterol. METHODS AND RESULTS In the second examination of the Gubbio population study from central Italy, 2650 cardiovascular disease-free men and women, aged 35-74 years around 1990, were examined and followed-up for 12 years. The classic risk factors (sex, age, systolic blood pressure, serum cholesterol and smoking habits) were studied as predictors of CHD and CVD events, alone and with the contribution of other factors (HDL cholesterol, blood glucose, serum triglycerides and waist circumference) included in the so-called MS, based on several multivariate models. MS was also tested after adjustment for other risk factors. MS produced a predictive significant relative risk of 1.67 for CHD events and 1.82 for CVD events, but considering its single risk factors, the only ones contributing to prediction were HDL cholesterol and systolic blood pressure. Dedicated analyses showed that MS does not add anything to the power of prediction beyond the role of the single risk factors treated in a continuous fashion, while the best predictive power is obtained using classic risk factors (sex, age, smoking habits, total cholesterol, systolic blood pressure) with the addition of HDL cholesterol. CONCLUSIONS The predictive power of MS is bound only to the presence of HDL cholesterol and blood pressure and does not add anything to using the same risk factor treated in a continuous fashion.

Abstract
AIM The aim of this study was to evaluate whether the primary tumour maximum standardized uptake value (SUV(max)) plays an independent prognostic role in patients with non small cell lung cancer (NSCLC) and whether this role is limited by partial volume effect (PVE) and motion artefacts. METHODS One hundred and fifty-three consecutive patients underwent PET exam, surgery (R0 resection) and follow-up (mean 20.3; range 6-44.8 months). Correlation with Disease Free and Overall Survival (DFS, OS) was evaluated in the entire population for: SUV(max), clinical and histopathological features and pathological stage. To evaluate the PVE and motion artefacts' interferences on SUV calculation, the correlation between SUV(max) and DFS/OS was also calculated in the groups of patients with tumour diameter ≥ and < than 25 mm (group A and B, respectively). RESULTS In the entire population only TNM and SUV(max) resulted correlated with DFS/OS. However, SUV(max) was significantly correlated with DFS/OS in group A but not in group B. Furthermore, only in the group of patients with primary tumour diameter ≥ 25 mm (group A), tumour diameter, tumour histotype, and tumour necrosis resulted significantly related with SUV(max) at both uni and multivariate analysis. CONCLUSION TNM together with SUV(max) could be useful in giving a better prognostic stratification of patients with NSCLC; however technical limitations in the SUV calculation must be taken into account in patients with tumour diameter <25 mm.

Abstract
Progressive supranuclear palsy (PSP) is a neurodegenerative disease with no sufficient treatment options to date. The most devastating symptom is the loss of balance with consecutive falls. Based on the observation that postural control improved in patients with vestibular dysfunction after audio-biofeedback training, we tested the effects of this training in PSP patients. Eight PSP patients were included into an uncontrolled 6-week intervention trial. The focus of the training was the improvement of posture and dynamic balance by using audio-biofeedback. The device was well accepted. No adverse events occurred. A significant improvement in the Berg Balance Scale was observed (T2 vs. T1, p=0.016), which remained significant at the 4-week follow-up (T3 vs. T1, p=0.008). Significant improvement of the Parkinson's disease questionnaire was demonstrated. No significant changes were found in the Timed Up-and-Go Test, the Five Chair Rise Test, and in specific clinical scales. To our knowledge, the present study is the first to demonstrate that audio-biofeedback training with PSP patients is associated with improvements of balance and psychosocial aspects.

Abstract
BACKGROUND Fatty liver is commonly associated with insulin-resistant conditions, often related to increased abdominal visceral fat. Our objective was to elucidate the specific roles of obesity, type 2 diabetes mellitus, insulin-resistance and abdominal fat distribution. MATERIALS AND METHODS The study population comprised 13 diabetic obese (DO), 10 nondiabetic obese (NDO), and nine normal-weight control (C) men aged 28-65 years, with normal plasma triglyceride levels. DO were in good glycaemic control (HbA1c = 6·8 ± 0·8%) (M ± SD) with diet (n = 8) or diet + metformin (n = 5). Liver fat content was measured by (1) H-magnetic resonance spectroscopy, abdominal fat distribution by magnetic resonance imaging and insulin sensitivity by hyperinsulinaemic euglycaemic clamp. RESULTS DO and NDO subjects had similar whole-body insulin resistance, BMI and waist circumference, higher than those of C subjects (P < 0·001). DO had more liver fat (11·9 ± 7·0%) than NDO (5·2 ± 2·8%, P < 0·05) and C (1·6 ± 1·0%, P < 0·001). Abdominal fat was greater in DO and NDO than in C (visceral: DO 3184 ± 843, NDO 2843 ± 1378 vs. C 1212 ± 587 cm(3), P < 0·001; subcutaneous: DO 4029 ± 362, NDO 5197 ± 1398 vs. C 2312 ± 626 cm(3), P < 0·001), visceral fat being not significantly different between the two obese groups, and subcutaneous fat significantly less in DO than in NDO (P < 0·05). CONCLUSIONS Type 2 diabetes is associated with increased fat accumulation in the liver, independent of obesity and whole-body insulin resistance. The increased liver fat in DO patients may be part of an altered regional fat distribution that includes an inadequate subcutaneous fat storing capacity, rather than simply being a consequence of increased abdominal visceral content.

Abstract
Basal cell carcinoma is the most common cutaneous malignant tumor, accounting for up to 80% of non melanoma skin cancers. Surgery, radiotherapy and chemotherapy have been for long time the main options for its treatment. Electrochemotherapy (ECT) is a novel local treatment successfully used in primary skin tumors. We report a case of a man affected by ulcerated basal cell carcinoma treated with ECT. In our case ECT was successful in the management of extensive basal cell carcinoma in clinical conditions whereas other approaches, would have been dangerous and inappropriate. To our knowledge, ECT must be considered as an alternative of traditional techniques when they are contraindicated in relation to the appearance of the lesions or the patient medical history.

Abstract
Climate and meteorological conditions greatly affect agricultural activities, modifying plant responses and determining the quantity and the quality of production. In this respect, the aim of this research was to analyze the quality of winter durum wheat (Triticum turgidum L. var. durum), in terms of protein content through the use of meteorological information. Meteorological conditions were described utilizing both local weather station data (air temperature, cumulated precipitation) and large-scale information available freely on the internet, such as geopotential height (GPH), sea surface temperature (SST), and the North Atlantic Oscillation (NAO) index. The analysis was carried out for the period 1997-2009 in the Tuscany region, Central Italy. Grain protein was positively correlated with air temperature during the February to June period, and negatively with cumulative precipitation during the entire period from November to June. Protein content was also negatively correlated with 500 hPa GPH over Gibraltar and North-Western Africa during the March to June period and with the SST of the Atlantic Ocean south-west of the Canary Islands during the January to June period. Finally, with regard to the NAO, winter durum wheat quality was positively correlated with the specific index for several months, in particular during the winter period. These results demonstrate that precipitation and air temperature over the production area represent two crucial variables driving the vegeto-productive responses of winter durum wheat. On the other hand, the use of large-scale meteorological information showed great potential from the perspective of a local quality forecast system setup.

Abstract
Piedras Moras reservoir (32° 10'27" S and 64° 16' 29" W; 832 ha), integrates a series of artificial lakes belonging to the Rio Tercero basin (Córdoba, Argentina). During March 2009 an algal bloom occurred, coinciding with several animal species mortality, mainly wild birds. The goal of this work was to establish the trophic status of the reservoir in relation to that mortality. Variables were evaluated in situ (temperature and water transparency) and samples were taken in order to identify algal species, Chl-a concentration (spectrophotometry) and toxins - total microcystines- (inmuno-enzymatic assay, ELISA). Histopathology studies were made on Fulica sp. A strong heterogenity in water transparency was observed, and "patches" of Potamogeton berteroanus distributed all along the lake, with Secchi disk minimal and medium values of 0.15 and 0.94 m. Chl-a concentration oscillated from 35.7 to 320.9 mg.m-3. Predominant phytoplankton species were Anabaena spiroides and Microcystis aeruginosa (Cyanophyceae). Water temperature was 27.8 °C (±0.88). Maximal value of total microcystine concentration was 0.23 μg.L-1. Chl-a concentration at the moment when mass mortality occurred (2.022 mg.m-3), and histopathological observations, strongly suggest that the animals' death was due to cianotoxins.

Abstract
A weekly administration of alternating irinotecan or oxaliplatin associated to 5-Fluorouracil in advanced colorectal cancer was planned in order to evaluate a new schedule maintaining dose intensities of each drug as in double combinations and tolerability of the triplet association. The following weekly schedule was administered: irinotecan, days 1 and 15; oxaliplatin, days 8 and 22; 5-fluorouracil (5-FU) over 12-h (from 10:00 p.m. to 10:00 a.m.) timed flat infusion, days 1-2, 8-9, 15-16 and 22-23, every 4 weeks. Dose- finding and phase II study were planned. Thirteen patients were enrolled in the dose-finding study and 23 in the phase II study. The recommended doses of our study are: irinotecan 160 mg/m(2); oxaliplatin 80 mg/m(2); 5-FU 900 mg/m(2). The dose-limiting toxicity was diarrhea (35% of patients) but no cases of febrile neutropenia were observed. In 30 patients assessable for response two complete (6.7%) and 18 partial (60%) responses were observed, for an overall response rate of 66.7% (alpha 0.05, CI+/-17). The triplet association using this weekly alternating schedule is an active and well-tolerated outpatient regimen. Surgical removal of residual disease was considered in 5 patients and a radical resection was performed in 5 patients (147 %).

Abstract
Control of balance is complex and involves maintaining postures, facilitating movement, and recovering equilibrium. Balance control consists of controlling the body center of mass over its limits of stability. Clinical balance assessment can help to assess fall risk and/or determine the underlying reasons for balance disorders. Most functional balance assessment scales assess fall risk and the need for balance rehabilitation but do not differentiate types of balance deficits. A system approach to clinical balance assessment can differentiate different kinds of balance disorders and a physiological approach can determine underlying sensorimotor mechanisms contributing to balance disorders. Objective measures of balance using computerized systems and wearable inertial sensors can bring more sensitive, specific and responsive balance testing to clinical practice.

Abstract
PURPOSE The typical appearance of focal nodular hyperplasia (FNH) in radiological contrast techniques (helical CT or MRI) includes homogeneous enhancement in the arterial phase, but the exact timing for the best visualization of this pattern is unknown. The aim of the present study was to assess the ultrasound pattern of FNH with special attention to real-time contrast-enhanced ultrasonography (CEUS) appearance and specifically to the timing of perfusion patterns. MATERIALS AND METHODS 72 patients (60 females, 12 males) with a total of 90 FNH nodules with a diameter ranging from 8 to 100 mm (mean +/- SD, 40.6 +/- 21.5 mm) were examined continuously for at least 4 minutes using CnTI and CPS methods (ESAOTE, Genoa, Italy and Acuson-Siemens) after bolus injection of SonoVue (BRACCO, Milan, Italy). RESULTS 87 of 90 nodules showed the typical coin-like hyperechogenicity in the arterial phase. The remaining three nodules were all in the same patient and were diagnosed as FNH after resection. Contrast started to appear within the lesions after a mean of 15.7 +/- 4.6 seconds (range 7 - 27 s) and reached peak signal intensity, with the greatest differentiation between the lesion and the surrounding parenchyma, at around 22.6 +/- 7.0 seconds (range 14 - 72 s). In the late phase, 65 lesions (72.2 %) became isoechoic (after a mean of 80.8 +/- 85.7 s, range 20 - 300 s), 22 (24.4 %) slightly hyperechoic and 3 (3.3 %) faintly hypoechoic. CONCLUSION FNH shows a typical homogeneous hyperechoic pattern during the arterial phase in real-time CEUS which disappears slowly on average but occasionally even as soon as 20 seconds after contrast injection. If the first scans are taken later than 20 seconds after injection (which is still considered to be a full arterial phase), the ultrasound hyperechogenicity may be missed in some cases. Real-time study of these lesions is therefore strongly recommended to avoid possible false-negative results.

Abstract
The involvement of the small bowel in systemic forms of amyloidosis may be diffuse or very rarely focal. Some cases of focal amyloidomas of the duodenum and jejunum without extraintestinal manifestations have been reported. The focal amyloidomas consisted of extensive amyloid infiltration of the entire intestinal wall thickness. Radiological barium studies, ultrasound and computed tomography (CT) patterns of diffuse small bowel amyloidosis have been described: the signs are non-specific and may include small-bowel dilatation, symmetric bowel wall thickening, mesenteric infiltration, and mesenteric adenopathy. No data are available about the positron emission tomography (PET)/CT and magnetic resonance imaging (MRI) patterns of intestinal amyloidosis. We report two cases of small bowel amyloidosis: the former characterized by focal deposition of amyloid proteins exclusively within blood vessel walls of the terminal ileum, the latter characterized by diffuse intestinal involvement observed on MRI and PET/CT studies.

Abstract
OBJECTIVES Both duloxetine and venlafaxine are efficacious in treating patients with Major Depressive Disorder (MDD), even though the advantages in treatment patients with bipolar disorder is unclear. This study aimed to evaluate the efficacy of duloxetine vs venlafaxine in the acute treatment of unipolar and bipolar depression. MATERIALS AND METHODS The study was a non randomized controlled trial. The participants were 62 consecutive outpatients (41 men; 21 women) affected by unipolar and bipolar depression treated either with duloxetine and venlafaxine. RESULTS More patients treated with duloxetine had a positive response to treatment and remission both for depression (HAMD17 response: 90.3% vs 0.0%; p < .001; HAM-D17 remission: 48.4% vs 0.0%; p < .001), and anxiety (HAM-A response: 90.3% vs 6.5%; p < .001; HAM-A remission: 71.0% vs 6.5%; p < .001) than controls. Patients treated with duloxetine were also more likely to show a decrease in HAM-D17 suicidality (100% vs 45.2%; p less than .001) and an increase in the quality of life (SF-36 percentage of improvement: 6.35 [SD=9.66 vs -2.58 [9.98]; p less than .001) than controls. CONCLUSIONS Duloxetine is more effective in reducing anxiety and suicidal ideation. Both treatments were safe and tolerated, and both may be successfully used in unipolar and bipolar depression.
