Abstract
OBJECTIVES We evaluated the possibility that a pattern of abnormal microRNA (miRNA) expression could be fuelling the mechanisms causing HIV-associated lipodystrophy (HAL). METHODS In this case-control study, samples of subcutaneous adipose tissue from eight consecutive HIV-infected patients on combination antiretroviral therapy with HAL (cases) were compared with those of eight HIV-negative subjects (controls). Human miRNA microarrays were used to probe the transcriptomes of the samples. Analysis of differentially expressed miRNAs was performed using DataAssist v2.0 software, applying a paired Student's t-test. RESULTS Data showed that 21 miRNAs out of 754 were overexpressed in the patient group. Ten of these (i.e. miR-186, miR-199a-3p, miR-214, miR-374a, miR-487b, miR-532-5p, miR-628-5p, miR-874, miR-125-b-1* and miR-374b*) were up-regulated to a significant degree (fold change >2.5; P < 0.01). Eleven other miRNAs (i.e. miR-let-7d, miR-24, miR-30c, miR-125a-3p, miR-149, miR-191, miR-196-b, miR-218, miR-342-3p, miR-452 and miR-454*) were 2- to 2.5-fold more expressed in HIV+ samples than in controls. Levels of mRNA for lipin 1, the target of miR-218, were significantly lower in subcutaneous adipose tissue from HIV patients. CONCLUSIONS In adipocytes of HIV-infected patients, the up-regulation of specific miRNAs could lead to an increased 'activation' that might contribute to the pathogenesis of HAL by increasing cell turnover and/or promotion of apoptosis.

Abstract
Atrial fibrillation is the most common arrhythmia in clinical practice. Ion channel blocking agents are often characterized by limited long-term efficacy and several side effects. In addition, ablative invasive procedures are neither easily accessible nor always efficacious. The "upstream therapy," which includes angiotensin-converting enzyme inhibitors, aldosterone receptor antagonists, statins, glucocorticoids, and ω-3 poly-unsaturated fatty acids, targets arrhythmia substrate, influencing atrial structural and electrical remodeling that play an essential role in atrial fibrillation induction and maintenance. The mechanisms involved and the most important clinical evidence regarding the upstream therapy influence on atrial fibrillation are presented in this review. Some open questions are also proposed.

Abstract
BACKGROUND AND AIMS Adiponectin is an adipokine highly and specifically expressed by adipose cells with antiatherogenic and antiinflammatory activities. The aim of the present study was to evaluate plasma adiponectin concentration in patients with primary hypertriglyceridemia and its relationship with metabolic parameters. METHODS AND RESULTS Male patients with primary hypertriglyceridemia and without the metabolic syndrome (n=22) were compared with normotriglyceridemic individuals (n=25). Plasma adiponectin concentration was measured by standardised enzyme-linked immunosorbent assay. Body mass index, waist circumference, glucose, insulin and non-esterified fatty acid levels, lipoprotein profile, and CETP activity were evaluated. Adiponectin levels were significantly decreased in hypertriglyceridemic patients in comparison with normotriglyceridemic subjects (4292+/-1717 vs. 6939+/-3249 ng/ml, p<0.005, respectively). Adiponectin was negatively associated with glucose (r=-0.44, p<0.01), insulin (r=-0.37, p<0.01), HOMA (r=-0.40, p<0.01), triglycerides (r=-0.36, p<0.01), VLDL-C (r=-0.34, p<0.05), and CETP (r=-0.47, p<0.001). Positive and significant correlations were observed with QUICKI (r=0.49, p<0.001) and HDL-C (r=0.33, p<0.05). In the multiple linear regression analysis, considering waist circumference, QUICKI, Log-triglycerides, HDL-C, and CETP as independent variables, Log-adiponectin showed a positive correlation with QUICKI, with an r(2)=0.229 and p<0.001. Therefore, the independent variable QUICKI explained the 23% of the variance in Log-adiponectin concentration. CONCLUSIONS We found low adiponectin levels in a population of primary hypertriglyceridemic men without the metabolic syndrome and an independent relationship between adiponectin concentration and insulin resistance. A reduction in insulin sensitivity and its impact on adiponectin concentration could be linked to high non-esterified fatty acid levels, increased triglyceride synthesis in the liver and impaired catabolism of triglyceride-rich lipoproteins.

Abstract
OBJECTIVES A program to promote occupational health among wood dust workers in the district of Civitavecchia. METHODS In recent years, occupational health physicians charged of medical surveillance of wood workers (Competent Physicians, CPs) had been invited to perform a peer-review of their methods and activities. In the present phase, CPs have been invited to show the result of their medical surveillance. RESULTS One hundred forty seven wood workers were submitted to rhinoscopic examination. The prevalence of woodwork-related rhinitis and other pathologic signs, including nasal adenocarcinoma (one case), was 32.7%. The prevalence of rhinitis in woodworkers increased with years of working as a woodworker. CONCLUSION Wood dust and chemical exposures in wood workers represent a serious risk of disease for the nasal cavity and paranasal sinuses.

Abstract
In this work we apply a trajectory classification approach, aiming at identifying the role exerted by meteorology on air quality in the Naples urban area (Southern Italy). Towards that end, the HYSPLIT (HYbrid Single-Particle Lagrangian Integrated Trajectory) model was used; backward trajectories were calculated for the period 1995-2004 and classified, based on a combination of the k-means and PCA (Principal Component Analysis) approaches. The robustness of the classification was strengthened using an ensemble approach, based on back-trajectories calculated for different (in the horizontal and vertical directions) arrival points around Naples and different arrival time. Eight clusters were identified, and the effects on air quality were evaluated. We focused on ozone and PM10 concentration, and evaluated to what extent the prevailing meteorological conditions were associated with different levels and temporal profiles of these two pollutants. We found that ozone and PM10 profiles share some similarities since they both load high during anti-cyclonic, subsiding conditions, a common situation during the summer months. During these days stagnation and recirculation effects enhance the concentration of locally emitted air pollutant. We also found that ozone exhibits a marked seasonal cycle, whose maxima appears during the summer season, but the discrimination with respect to the area of origin indicated the presence of a second relative maxima, appearing early during the spring season. PM10 pollution levels often exceed the annual limit of 50 microg/m(3). The days associated with a significant exogenous contribution from the North African countries were identified.

Abstract
One of the most frequent anesthesiological manoeuvres is orotracheal intubation (OTI). Many complications can occur during OTI, one of these is the rupture of the trachea (TR) and/or of the bronchi. The aim of this study is to highlight the risk of TR during OTI. Over a period of three years of activity (1997-1999) in the Cardiothoracic Department of Pisa University nine patients we treated, eight of which were women ranging from 35 to 95 years of age. In the majority of the cases clinical signs like subcutaneous emphysema of the face and neck, hemoptysis and dyspnoea, variably combined were present. An X-ray of the thorax carried out on six patients did not permit the diagnosis. Bronchoscopy was the diagnostic examination in all nine patients. Seven cases were treated by senior anaesthesiologists, without stilet and OTI was easy. Predictive elements for difficult intubation were not observed in any case. Only one patient had a voluminous intrathoracic goitre dislocating the trachea. The nine patients were all treated surgically as they were all symptomatic and with important transmural lacerations that caused pneumothorax or pneumomediastinum. The survival percentage in the third month is 100%. Although rare TR must be suspected when clinical signs are present; bronchoscopy is the examination which permits diagnosis and a correct therapy.

Abstract
ABSTRACT Recombinant single-chain variable fragment antibodies (scFv) that bind specifically to Citrus tristeza virus (CTV), which cause the most detrimental viral disease in the citrus industry worldwide, were obtained from the hybridoma cell lines 3DF1 and 3CA5. These scFv were genetically fused with dimerization domains as well as with alkaline phosphatase, respectively, and diagnostic reagents were produced by expressing these fusion proteins in bacterial cultures. The engineered antibodies were successfully used for CTV diagnosis in plants by tissue print enzyme-linked immunosorbent assay (ELISA) and double antibody sandwich-ELISA. The fully recombinant ELISAs were as specific and sensitive as conventional ELISAs performed with the parental monoclonal antibodies, showing the usefulness of recombinant antibodies for routine detection of a virus in woody plants for the first time.

Abstract
Global motion is very likely to occur in image sequences analysis. For example, it arises if the observer is moving during the sequence acquisition (ego-motion). Our aim is to get a simple method to estimate in a reliable may a set of parameters that can take into account the presence of a global motion component, using only local information. The novelty of our approach is in regarding spatial shift, change of scale, and rotation (corresponding to usual camera effects such as pan and zoom) as a two-dimensional (2-D) Doppler effect. The mathematical treatment is carried on in the complex plane, so that the results can be easily deduced as an extension of the one-dimensional (1-D) case; in this way, we obtain simple expressions, well suited for a practical realization of the estimate. The method has been experimentally validated by both real pictures with a synthetic motion and real image sequences.
