Evoluzione del sistema bancario e finanziamento dell’economia nel Mezzogiorno (Developments in the Banking Market and Company Financing in the Italian Mezzogiorno)
Fabio Panetta
Moneta e Credito , 2003,
Abstract: In the 1990s the banks established in the Italian South have reduced their cost-income ratios and improved their ability to screen customers, increasing profitability. The spread between the loan rates in the South and North has narrowed substantially. Taking into account differences in the size and industry composition of firms in the two areas, the spread is currently equal to 0.90 percent. The growth of loans in the North has outpaced that in the South, but this divergence is merely a reflection of the greater proportion of new bad loans in relation to total lending in the South. Since the mid-1990s in the South the ratio of loans to local firms to funds raised locally has increased from 75 to 85%. The lower value of the ratio in the South reflects structural features of the Southern economy and the way in which loans are allocated geographically in financial statistics.
Crohn’s Disease and Urinary Manifestations: A Crohn’s Intestinal Disease Mimicking a Bladder Mass  [PDF]
Bronislava Papadatou, Lidia Monti, Giuliano Torre, Fabio Panetta, Antonella Diamanti
Health (Health) , 2014, DOI: 10.4236/health.2014.612182
Abstract: We report a rare mode of presentation of Crohn’s Disease (CD) in a 17-year-old boy, who was admitted at our hospital due to abdominal pain, dysuria, polyuria and fever. The ultrasound showed an increased wall thickness of the small bowel and cecum and a vegetating lesion adjoined into the bladder. The histology was not suggestive of CD and it excluded the bladder neoplasm. Based on the biochemical assessment and the imaging, we started the treatment specific for CD (nutritional therapy by Modulen, short courses of steroids, azathioprine and mesalazine during the follow up), These treatments improved the gastrointestinal symptoms and the nutritional status of our patient but also induced the disappearance of the mass adjoined into the bladder. In spite of the severe onset, in this patient, the clinical course of CD was mild and responder to conventional therapy.
Ulcerative Colitis and Acute Thrombocytopenia in a Pediatric Patient: A Case Report and Review of the Literature  [PDF]
Bronislava Papadatou, Fiammetta Bracci, Daniela Knafelz, Antonella Diamanti, Maria Sole Basso, Fabio Panetta, Filippo Torroni, Valerio Nobili, Giuliano Torre
Health (Health) , 2014, DOI: 10.4236/health.2014.612184
Abstract: We report the case of a 14-year-old boy affected by ulcerative colitis (UC) and acute thrombocytopenic purpura (ITP) with simultaneous onset. UC diagnosis was based on symptoms, endoscopy and histology findings. ITP diagnosis was based on the normal bone marrow megakaryocyte count, the presence of platelet associated IgG and the absence of splenomegaly. Medical treatments including high doses of steroids, intravenous immunoglobulins were ineffective on ITP course, while UC course was mild for several months after the onset. When colonic inflammation became untractable not responsive at steroids and immunosuppressive agents, colectomy resolved both pathologies.

Nutrients , 2014, DOI: 10.3390/nu6010207
Abstract: The clinical presentation of celiac disease in children is very variable and differs with age. The prevalence of atypical presentations of celiac disease has increased over the past 2 decades. Several studies in adults and children with celiac disease indicate that obesity/overweight at disease onset is not unusual. In addition, there is a trend towards the development of overweight/obesity in celiac patients who strictly comply with a gluten-free diet. However, the pathogenesis and clinical implications of the coexistence of classic malabsorption (e.g., celiac disease) and overweight/obesity remain unclear. This review investigated the causes and main clinical factors associated with overweight/obesity at the diagnosis of celiac disease and clarified whether gluten withdrawal affects the current trends of the nutritional status of celiac disease patients.

Abstract:

Background: Heart disease is now considered an inflammatory process targeted primarily by medical therapy on lipid levels. Complementary and alternative medicine searches for novel non-pharmacologic therapy, including pursuing various diets. Animal studies and consumer literature suggest benefits of vinegar on lipid levels and diabetes mellitus. Our nonrandomized pilot study from our group suggested a benefit in raising high-density lipoprotein cholesterol (HDL-C). Based on this data, we conducted a randomized placebo controlled clinical trial to determine the effects of apple cider vinegar intake in those without diabetes mellitus on total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides, HDL-C, Hemoglobin A1C(Hgb-A1C) and measurement of inflammation with high sensitivity CRP levels (HS-CRP). Methods: A prospective randomized, double blind, placebo-controlled clinical trial consisting of 114 participants was conducted. Participants consumed 30 mL of either apple cider vinegar or placebo for two months. Measurements were collected at baseline, eight and sixteen weeks. The primary endpoint was the change in HDL-C from baseline to eight weeks between the vinegar and placebo groups. Secondary endpoints were change from baseline to eight weeks in TC, LDL-C, triglycerides, Hgb-A1cand HS-CRP. Results: Change in serum HDL-C concentration was not significantly different between the vinegar and control groups after eight weeks of supplementation. Secondary endpoints including TC, LDL-C, Hgb-A1cand HS-CRP were not statistically different at the Bonferroni corrected significance level of 0.01. No significant difference was found regardless of baseline HDL-C levels. Conclusions: We found no significant difference in HDL-C, LDL-C, triglycerides, total cholesterol, or HS-CRP levels with use of vinegar but a trend down of Hgb-A1cin this group of non-diabetic participants. Further investigation is required to define the impact of vinegar in those with diabetes mellitus.

Comparative strengths of a pseudo-spectral time domain method in numerical simulation of single particle optical scattering
R. L. Panetta,>C. Liu,>P. Yang
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali , 2011, DOI: 10.1478/c1v89s1p074
Abstract: We present some results on the relative performance of the pseudo-spectral time domain, finite difference time domain, and DDA methods in calculating single-particle optical scattering properties. Our interest is in particles with size parameters in excess of 10. Using as test case a homogeneous spherical particle we have found that the pseudospectral time domain method is generally more efficient (uses less cpu time for a given accuracy) than the finite-difference time domain method. The DDA method appears to be superior to the pseudo-spectral method for indices of refraction less than 1.5, but as the index of refraction increases, the pseudo-spectral method becomes superior. We present here some results for particles with size parameters 10 and 30, and indices of refraction 1.3117 and 1.7.
Tensile Structures of Cables Net, Guidelines to Design and Applications  [PDF]
Fabio Rizzo
Open Journal of Civil Engineering (OJCE) , 2016, DOI: 10.4236/ojce.2016.62023
Abstract: The structural engineering design of not conventional typologies imposes a complex path that begins evaluating procedures of a preliminary design and ends with complex procedures to validate the analysis response. Any guide lines to follow are often available. About complex shapes, in particular, any details are presented in the codes to evaluate wind action and so wind tunnel experiments are necessary to valuate this. The evaluation of wind tunnel data is a complex process that often needs new and specific subroutines programmed by researchers. The difficult increases when the objective is to study a not specific building but general aspects as for examples the dependence of a generic phenomenon by a geometric sample; in this case it is necessary to design and to program numerical subroutines before and then the wind tunnel experiments. Often, these subroutines are left detached and are non-generalizable process. Purpose of this paper is to describe a complete procedure to pre- and post-process wind tunnel data with the objective to design a not convectional structure as a tensile structure. In this particular case the research aim is a parametrization of the aerodynamic behavior of Hyperbolic Paraboloid roofs, shape used for cables net. The reason of the experiments is the absence in the international codes of the pressure coefficients for these geometries. The paper describes the numerical procedure evaluated to choose a sufficient representative geometric sample, the numerical procedure evaluated to design and to construct the wind tunnel models and FE models, the numerical procedure to evaluate and to use for FEM analyses of the wind tunnel data, the numerical procedure to calculate nonlinear structural analysis, and, finally some applications. All these numerical procedures use basic theory derived for example by the cable theory, the fluid mechanic, the nonlinear geometric analysis and other. However specific codes were necessary and were programmed to apply the theories on the specific case of study; the complete methodology followed is presented. The goal is to create a free open domain where the numerical procedures evaluated are merged, added, modified by researchers with the aim to obtain a common space of use for wind engineering of not conventional structure.
Modelling the Effects of Paclitaxel and Cisplatin on Breast and Ovarian Cancer

Computational and Mathematical Methods in Medicine , 2000, DOI: 10.1080/10273660008833061
Abstract: The two drugs, Paclitaxel and Cisplatin, have important roles in the treatment of breast and ovarian cancer, with the combination currently considered the optimum first line chemotherapy of epithelial ovarian cancer. There has been a variety of experimental and clinical studies to try to determine the most effective method to deliver these drugs. These studies consistently show that giving Paclitaxel prior to Cisplatin is the more effective regimen. However, the reasons why are not fully understood. Therefore, we have developed a mathematical model to describe and predict the effects of these two drugs. This model takes into account the cytotoxic effects of the drugs on the cell-cycle and the pharmacodynamic and pharmacokinetic effects of the drugs on each other. The model agrees with the experimental and clinical studies which show that Paclitaxel given prior to Cisplatin is the better combination and, in addition, the model also predicts more effective treatment regimens. These include conditions on the time between doses and the dosing of each of the drugs.
Percutaneous Management of a Long Saphenous Vein Graft Aneurysm: A Case Report and Review of Literature
Carmelo J. Panetta,Williaim Schneider,Max A. Boller
Cardiology Research and Practice , 2009, DOI: 10.4061/2009/981292
Abstract: Aneurysms of saphenous vein grafts are rare but can result in complications such as myocardial infarction or death. Percutaneous treatment has included a variety of approaches, including covered stents. Long aneurysms in saphenous vein grafts pose an additional challenge due to the lack of coronary covered stents with sufficient length. We present successful treatment of a long saphenous vein graft aneurysm with use of peripheral covered stents over two coronary guidewires, a 55-centimeter 8-French sheath and no guide catheter.

Abstract: Breast cancer mortality rates across the entire population in the USA have remained almost unchanged since 1970 [1]. In terms of numbers, it is estimated that 43 300 women died of breast cancer in the USA in 1999 [2]. Those who succumbed to this disease did so as a consequence of metastatic dissemination or the treatment of metastasis. A large percentage of these women were treated with cytotoxic chemotherapy, with drugs that are demonstrated to be effective against breast carcinoma cells both in vitro and in vivo. Nevertheless, despite being treated with the optimal doses at the optimal schedule, a significant percentage of women will relapse and die. For example, recurrence-free and survival rates at 10 years for women receiving polychemotherapy, for all ages, as estimated in the Oxford Overview, were 44 and 51.3%, respectively [3].This leads us to ask several questions. First, why are these treatments unable to cure a large percentage of women? Is it the result of cells that are resistant, either kinetically or by means of clonal evolution, to the drugs? Is it a problem of inefficient delivery to the tumor cells or a problem that pertains to the tumor microenvironment? A second question, undoubtedly related to the first set of questions, is why does breast cancer continue to recur up to 20 years after treatment of the primary tumor [4,5,6,7,8,9,10].One discipline that can be helpful in answering the questions posed above is mathematical modeling. It has been observed that trial and error manipulation of cancer treatment can be an inefficient method of understanding and developing treatment strategies [11,12**]. The use of mathematical models can aid researchers by explaining why some strategies fail; by suggesting refinements to current clinical approaches; and, finally, by suggesting alternative treatment strategies based on mathematical models that are derived from both known and hypothesized physiologic phenomena. Furthermore, many variations in the alternativ
