Abstract
Telomere length (TL) is a biomarker for cellular senescence and TL erosion is predictive of the risk for age-related diseases. Despite being genetically determined at birth, TL may be susceptible to modifications through epigenetic mechanisms. Pollutant agents are considered one of the major threats to both human and planetary health. Their ability to cross the placental barrier and induce oxidative stress in fetal cells is particularly concerning and it may be associated with early TL erosion. In consideration of the timely relevance of this topic, we conducted a literature review on the impact of prenatal exposure to pollutant agents on newborn TL. The search yielded a total of 1099 records, of which only 32 met the inclusion criteria for the review. These criteria included the participation of human subjects, a longitudinal design or collection of longitudinal data, reporting of original TL data, and a focus on exposure to pollutant agents. The majority of the studies reported a significant inverse association between prenatal exposure to pollutant agents and TL. Furthermore, the second trimester of pregnancy emerged as a special sensitive period for the occurrence of pollutant agent-driven TL modifications. Sex differences were inconsistently reported across studies. This review contributes to highlighting biochemical pathways for the threats of environmental pollution to human health. Future research is warranted to further highlight potential buffering mechanisms.

Abstract
This study reports the outcomes of a literature survey aimed at exploring how different environmental factors-that is acoustic, thermal, visual, and air quality stimuli-interact in affecting building occupants' perception and performance. Recent laboratory studies have been collected, and their methodological approaches reviewed in terms of experimental design, adopted exposures conditions, perception and performance assessment methods. Results have been summarized and compared to identify interaction patterns between environmental factors and possible practical implications for improving the design of both experimental studies and the built environment. The analysis allows highlighting limitations, potential improvements and future opportunities in this field of research, thus providing a reference for further investigations aimed at a deeper understanding, modeling, and prediction of the impacts caused by the main indoor variables on human comfort and performance.

Abstract
Exposure of human blood ex vivo to oxygen-ozone (O2- O3) using either dialysis exchangers or normal oxygenators gives rise to a number of problems, one of which linked to platelet activation, leads to rapid occlusion and no gas exchange. Semipermeable membranes were found unsuitable because, except for one, they were gas-transfer inefficient, allowed ultrafiltration and were more or less vulnerable to O3. Over the last three years we have examined several types of hydrophobic O3-resistant hollow fiber capillaries but, if the polypropylene surface is not properly coated, there is platelet aggregation and blood coagulation. These problems while far less relevant with O2 alone, become prohibitive in the presence of ozone. Recently new oxygenators have been prepared with special materials to make them more biocompatible and it has become possible to oxygenate and ozonate up to 5L of blood in about an hour, thus making the treatment of critical patients feasible.

Abstract
The self-locating catheter invented by Nicola Di Paolo has been increasingly used in Italy and elsewhere since 1994, with about a thousand patients currently implanted every year. Twelve grams of tungsten inserted in the tip of the conventional Tenckhoff catheter during extrusion do not significantly change its form, but suffice to keep the tip firmly in the Douglas cavity. The validity of the new catheter is confirmed by a multicentric controlled study in a large population of peritoneal dialysis patients. This trial showed that patients with the new catheter have fewer episodes of peritonitis, tunnel infection, cuff extrusion, catheter malfunction, obstruction and leakage. This paper outlines the present situation and reports a comparative analysis of the costs of Tenckhoff and self-locating catheters.

Abstract
The present study focused on inhibition of HSV-1 and -2 replication and pathogenesis in vitro and in vivo, through the selective targeting of the envelope glycoprotein D. Firstly, a human monoclonal antibody (Hu-mAb#33) was identified that could neutralise both HSV-1 and -2 at nM concentrations, including clinical isolates from patients affected by different clinical manifestations and featuring different susceptibility to acyclovir in vitro. Secondly, the potency of inhibition of both infection by cell-free viruses and cell-to-cell virus transmission was also assessed. Finally, mice receiving a single systemic injection of Hu-mAb#33 were protected from death and severe clinical manifestations following both ocular and vaginal HSV-1 and -2 lethal challenge. These results pave the way for further studies reassessing the importance of HSV entry as a novel target for therapeutic intervention and inhibition of cell-to-cell virus transmission.

Abstract
Nutritional abnormalities and physical inactivity are risk factors of increased morbidity and mortality in patients with ESRD. Identify and define malnutrition, in particular protein-energy depletion (PEW), is an important task in the management of renal patients. The aim of this multicenter observational study was to implement the assessment of nutritional status and functional capacity in patients on peritoneal dialysis, including tests and validated methods which are relatively easy to apply in daily clinical practice. The study includes all the 133 prevalent patients (80 m, 53 f, age 65 14 years), in peritoneal dialysis treatment (vintage 26 19 months) in 9 centers in Tuscany. We performed anthropometry, bioimpedance (BIA), clinical biochemistry, evaluation of habitual physical activity (RAPA tests) and performance (Sit-To-Stand test), appetite-evaluation questionnaire, and indices including the Malnutrition Inflammation Score (MIS), Geriatric Nutrition Risk Index (GNRI), Charlson comorbidity index, Barthel and Karnowsky index. The latter showed a condition of dependence in 7.2% and 19.7% of cases, respectively. Poor appetite was recorded in 48.2%. The majority of patients fell within the overweight / obesity range (51%) with waist circumference values associated with increased cardiovascular risk in 51% of males and 60% of females. At the BIA analysis, a BCMI <8 kg/m2 was detected in 39% of patients; an estimated protein intake <1.0 g / kg/d was found in 59% of cases; 34% of patients had serum albumin <3.5 g / dl; control of acidosis was good (bicarbonate 25.4 3.8 mM) but hyperphosphatemia was present in 64.6% of patients. A condition of sedentary or light physical activity was reported by 65.1% of patients, vigorous activity only by 11.9%. The 86.5% of patients able to perform the Sit-to-stand test reported a lower than the reference values for age and sex. A diagnosis of PEW was possible in 8% of our series, while a MIS score> 11, indicative of PEW, took place in 12.7% of cases. The values of the MIS correlated directly with age and the degree of comorbidity and inversely with the sit-to-stand test, RAPA tests and appetite level. The data in this study show that single tests indicative of malnutrition disorders are frequent to be found in our series of peritoneal dialysis patients. However, a diagnosis of PEW is quite infrequent. A large percentage of patients are overweight with increased abdominal adiposity, and reduced cell mass and protein intake below recommended levels; the level of habitual physical activity is low, and the level of physical capability is scarce. Therefore it is conceivable a nutritional counseling intervention to increase the intake of proteins, limiting the phosphorus and (when indicated) energy intake and to stimulating spontaneous physical activity or arranging assisted programs for functional rehabilitation. Close monitoring of the nutritional status and implementation of programs of adapted physical activity should have a prominent role in the clinical management of patients on peritoneal dialysis.

Abstract
The global burden of herpes simplex virus (HSV) legitimates the critical need to develop new prevention strategies, such as drugs and vaccines that are able to fight either primary HSV infections or reactivations. Moreover, the ever-growing number of patients receiving transplants increases the number of severe HSV infections that are unresponsive to current therapies. Finally, the high global incidence of genital HSV-2 infection increases the risk of perinatal transmission to newborns, in which disseminated infection or central nervous system (CNS) involvement is frequent, with associated high morbidity and mortality rates. There are several key features shared by novel anti-HSV drugs, from currently available optimized drugs to small molecules able to interfere with various virus replication steps. However, several virological aspects of the disease and associated clinical needs highlight why an ideal anti-HSV drug has yet to be developed.

Abstract
It is known that even the adaptive components of the immune system are based on genetic traits common to all individuals, and that diversity is shaped by the lifelong contacts with different non-self antigens, including those found on infectious pathogens. Besides the individual differences, some of these common traits may be more prone to react against a given antigen, and this may be exploited by the infectious pathogens. Indeed, viral infections can deregulate immune response by subverting antibody (Ab) gene usage, leading to the overexpression of specific Ab subfamilies. This overexpression often results in a protective antiviral response but, in some cases, also correlates with a higher likelihood of developing humoral autoimmune disorders. These aspects of virus-induced autoimmunity have never been thoroughly reviewed, and this is the main purpose of this review. An accurate examination of virus specific Ab subfamilies elicited during infections may help further characterize the complex interplay between viruses and the humoral immune response, and be useful in the design of future monoclonal antibody (mAb)-based anti-infective prophylactic and therapeutic strategies.

Abstract
The fine characterization of protective B cell epitopes plays a pivotal role in the development of novel vaccines. The development of epitope-based vaccines, in fact, cannot be possible without a clear definition of the antigenic regions involved in the binding between the protective antibody (Ab) and its molecular target. To achieve this result, different epitope-mapping approaches have been widely described (Clementi et al. Drug Discov Today 18(9-10):464-471, 2013). Nowadays, the best way to characterize an Ab bound region is still the resolution of Ab-antigen (Ag) co-crystal structure. Unfortunately, the crystallization approaches are not always feasible. However, different experimental strategies aimed to predict Ab-Ag interaction and followed by in silico analysis of the results may be good surrogate approaches to achieve this result. Here, we review few experimental techniques followed by the use of "basic" informatics tools for the analysis of the results.

Abstract
JC virus (JCPyV) has gained novel clinical importance as cause of progressive multifocal leukoencephalopathy (PML), a rare demyelinating disease recently associated to immunomodulatory drugs, such as natalizumab used in multiple sclerosis (MS) cases. Little is known about the mechanisms leading to PML, and this makes the need of PML risk stratification among natalizumab-treated patients very compelling. Clinical and laboratory-based risk-stratification markers have been proposed, one of these is represented by the JCPyV-seropositive status, which includes about 54% of MS patients. We recently proposed to investigate the possible protective role of neutralizing humoral immune response in preventing JCPyV reactivation. In this proof-of-concept study, by cloning the first human monoclonal antibody (GRE1) directed against a neutralizing epitope on JCPyV/VP1, we optimized a robust anti-JCPyV neutralization assay. This allowed us to evaluate the neutralizing activity in JCPyV-positive sera from MS patients, demonstrating the lack of correlation between the level of anti-JCPyV antibody and anti-JCPyV neutralizing activity. Relevant consequences may derive from future clinical studies induced by these findings; indeed the study of the serum anti-JCPyV neutralizing activity could allow not only a better risk stratification of the patients during natalizumab treatment, but also a better understanding of the pathophysiological mechanisms leading to PML, highlighting the contribution of peripheral versus central nervous system JCPyV reactivation. Noteworthy, the availability of GRE1 could allow the design of novel immunoprophylactic strategies during the immunomodulatory treatment.

Abstract
Defining immunogenic domains of viral proteins capable of eliciting a protective immune response is crucial in the development of novel epitope-based prophylactic strategies. This is particularly important for the selective targeting of conserved regions shared among hypervariable viruses. Studying postinfection and postimmunization sera, as well as cloning and characterization of monoclonal antibodies (mAbs), still represents the best approach to identify protective epitopes. In particular, a protective mAb directed against conserved regions can play a key role in immunogen design and in human therapy as well. Experimental approaches aiming to characterize protective mAb epitopes or to identify T-cell-activating peptides are often burdened by technical limitations and can require long time to be correctly addressed. Thus, in the last decade many epitope predictive algorithms have been developed. These algorithms are continually evolving, and their use to address the empirical research is widely increasing. Here, we review several strategies based on experimental techniques alone or addressed by in silico analysis that are frequently used to predict immunogens to be included in novel epitope-based vaccine approaches. We will list the main strategies aiming to design a new vaccine preparation conferring the protection of a neutralizing mAb combined with an effective cell-mediated response.

Abstract
Peritoneal sclerosis is very common in peritoneal dialysis (PD) patients. It can vary from the mild, clinically silent sclerosis always present after years of PD, to rare but dramatic and often fatal cases. In our opinion, peritoneal sclerosis is a single disorder, so its variable manifestations are different stages of one nosological entity: this opinion relies mainly on strong connections in pathophysiology. In our view, the frequency, pathology, animal models, etiology and pathogenesis often show a bimodal configuration with suggests that peritoneal sclerosis is actually two distinct nosological entities: simple sclerosis and sclerosing peritonitis. The former is very frequent, with minor anatomical alterations and low clinical impact; it is reproducible in animals by means of PD, and is clearly due to the poor biocompatibility of PD. The latter is rare, with radical anatomical alterations and high mortality; it can only be reproduced in animal models by means other than PD and seems to be due to factors both related and unrelated to PD.

Abstract
BACKGROUND Since 1990 our group has been using extracorporeal circulation to ozonate blood by an original method, known as extracorporeal blood oxygenation and ozonation (EBOO), with the aim of amplifying the results observed with ozone autohemotherapy. OBJECTIVE To verify the hypothesis that EBOO improves the skin lesions typical of peripheral artery disease (PAD) patients. METHODS Twenty-eight patients with PAD were randomized to receive EBOO or intravenous prostacyclin in a controlled clinical trial. The primary efficacy parameters were regression of skin lesions and pain,and improvement in quality of life and vascularisation. RESULTS Patients treated with EBOO showed highly significant regression of skin lesions with respect to patients treated with prostacyclin. Other parameters that were significantly different in the two groups of patients were pain,pruritus, heavy legs and well-being. No significant differences in vascularisation of the lower limbs before and after treatment were found in either group. No side effects or complications were recorded during the 210 EBOO treatments. CONCLUSION EBOO was much more effective than prostacyclin for treating skin lesions in PAD patients and also had a positive effect on patient general condition without any apparent change in arterial circulation. This suggests other mechanisms of action of EBOO.

Abstract
A case of necrotizing fasciitis in a dialysis patient is described. Since traditional therapies were unsuccessful, extracorporeal blood oxygenation and ozonation (EBOO) was tried. This technique is no longer in the experimental stage and is used routinely in our hospital. Patient condition improved radically after EBOO.

Abstract
Exposure of human blood ex vivo to oxygen-ozone (O2-O3) using either dialysis exchangers or normal oxygenators gives rise to a number of problems, one of which linked to platelet activation, leads to rapid occlusion and no gas exchange. Semipermeable membranes were found unsuitable because, except for one, they were gas-transfer inefficient, allowed ultrafiltration and were more or less vulnerable to O3. Over the last three years we have examined several types of hydrophobic O3-resistant hollow fiber capillaries but, if the polypropylene surface is not properly coated, there is platelet aggregation and blood coagulation. These problems while far less relevant with O2 alone, become prohibitive in the presence of ozone. Recently new oxygenators have been prepared with special materials to make them more biocompatible and it has become possible to oxygenate and ozonate up to 5L of blood in about an hour, thus making the treatment of critical patients feasible.

Abstract
Ninety-eight consecutive patients with ampullary and periampullary carcinoma diagnosed between 1983-1993 were studied retrospectively. Among these patients, 66 had a carcinoma of the head of the pancreas, 10 a carcinoma of the papilla of Vater, 8 a carcinoma of the duodenum, and 14 a carcinoma of the distal common bile duct. Resectability rate ranged from 12% to 90% according to the tumor location and histologic type. Palliative procedures such as laparotomy, biopsy and bilio-digestive bypasses were performed in 27 patients. Curative resections were performed in 24 cases: 20 pancreatoduodenectomies, 2 total pancreatectomies, 1 duodenectomy, 1 common bile duct resection. The results of the surgical treatment as well as mortality and morbidity rates were compared with those of different and larger series.

Abstract
In the last 5 years 16 patients with cholecystosis were observed. In this period the most recent diagnostic and therapeutic techniques were used including ultrasound which allowed to diagnose 60% of adenomyomatosis, 33.3% of cholecystosis and 6.7% of gallbladder polyposis. In 6 cases a traditional open surgery cholecystectomy was performed, while the videolaparascopic approach was used in other 6 cases. Histologic examination always confirmed the preoperative diagnosis, however in one case a gallbladder cancer was histologically found; this case had been clinically diagnosed 9 years previously as adenomyomatosis. Therefore, our experience suggest, in agreement with others, that cholecystosis should be considered as a precancerous lesion.

Abstract
In the last 3 years, 300 consecutive patients (110 men, 190 women) were treated for gallstone disease using either traditional open surgery or the video laparoscopic approach. The relative clinical data and results were compared and analysed. The Authors conclude that video laparoscopy presents a number of advantages such as minor costs, reduced pain, quick return to work, compared to traditional surgery, especially when correctly indicated.

Abstract
In the last 5 years 25 patients (11 men, 14 women) with carcinoma of the extrahepatic biliary duct were studied. The most frequent localization of the carcinoma was the hepatic hilum. D.C.P. according to Whipple was possible only in one patient, while in 20 patients a palliative approach with external and internal biliary derivations was the choice. In the remaining 4 patients an explorative laparotomy with biopsy was performed. It is concluded that palliative resection allows for a better quality of life.

Abstract
In order to assess the efficacy and tolerability of gallopamil (D-600, CAS 16662-47-8) by long-term venous infusion in the treatment of spontaneous angina, 15 consecutive patients were studied in a single-blind, self-controlled trial versus placebo. Following a 24-h Holter ECG recording of the patients receiving a saline infusion (run-in phase), i.v. administration of gallopamil was started at a dose of 0.02 mg/kg/h preceded by a 0.03 mg/kg bolus. After 24 h, the dosage was increased to 0.03 mg/kg/h and the infusion was maintained for another 48 h. The Holter ECG recording was repeated in the last 24 h of treatment and after 6 h from withdrawal (washout phase). The reduction in the number of angina attacks, as shown by a comparison between the average of the two placebo periods (run-in and washout phases) and the three days of treatment, was 68.2%, 92.5%, and 87%, respectively. Consumption of glyceryl trinitrate decreased by 92.5% on each one of the three days of treatment. The reduction in the number of ischemic episodes (IEs) with symptomatic (-91.6%) and silent (-98.0%) ST elevation, and with symptomatic (-100%) and silent (-90%) ST depression, also proved significant. Heart rate decreased only moderately. One patient showed a mild first-degree heart block, while another suffered a transient episode of isorhythmic A-V dissociation. In conclusion, when administered by venous infusion, gallopamil has been found to be well tolerated and highly effective in the treatment of spontaneous angina.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The efficacy of a new calcium channel blocker, gallopamil, has been tested via a single blind, self-controlled versus placebo protocol in 9 consecutive patients admitted to our Coronary Care Unit because of repeated daily attacks of Prinzmetal variant angina. Exclusion criteria were age (greater than 65 years) bradycardia (less than 50 beats/min), recent myocardial infarction, heart failure, sinoatrial or atrioventricular block. After a 24 hours run-in period on saline drip, gallopamil was administered as 0.03 mg/kg bolus followed by continuous infusion at 0.02 mg/kg/h for the first 24 hours and 0.03 mg/kg/h for the last 48 hours. Treatment was then stopped and the patients were again kept on saline infusion for the next 30 hours. Holter monitoring was recorded during run-in, on third day of treatment and 6 hours after gallopamil withdrawal. Anginal attacks were significantly reduced in number by therapy (-63%, -91%, -84% in the 3 days of treatment). Holter monitoring during gallopamil infusion showed a statistically significant reduction in silent (-98%) and symptomatic (-93%) ischemic episodes (IE). During the last 24 hours of the washout period we observed a statistically significant increase in silent ischemic episodes. While no transient ST segment elevation was recorded in 3 patients, in 1 patient symptomatic IE were increased of 150% with respect to the run-in period. On the whole we observed complete suppression of IE in 7 patients (78%) at the third day of treatment with gallopamil. In 2 patients (22%) a greater than 75% reduction was observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Alterations in cardiovascular function induced by the acute intravenous administration of verapamil (5 or 10 mg) in 52 patients (29 with ischemic heart disease and 23 without heart disease) were evaluated with use of invasive techniques (right and left heart catheterization, left ventricular cineangiography, and coronary arteriography). The most significant changes were represented by a decrease in systemic vascular resistance and systemic arterial pressure, and an increase in heart rate and cardiac output. Contractility indexes were not depressed in either group, and altered ventricular wall motion tended to improve to a slightly smaller degree than in patients treated with nitroglycerin. The use of verapamil in patients with ischemic heart disease appears to be safe, and concern about the negative inotropic influences in humans no longer seems justified.

Abstract
The literature on reconstructive femoro-tibial surgery includes distal by-pass implantation, personally considered the most interesting and most debated part. Four cases treated with double femoro-popliteal and popliteo-tibial reconstruction, three with the jump-by-pass technique and one with the sequential-by-pass technique are reported. Of these cases, three are complete with fluximetric and angiographic examination before, during and after the operation. Final results are considered satisfactory, notwithstanding certain inconveniences which were dealt with as they arose. Long-term follow-up permits some optimism for the future of this surgery, although the technical difficulties are by no means negligible.

Abstract
Four cases of superiore mesenteric artery syndrome are presented. Reference is made to the difficulties involved in the clinical diagnosis of this form. It is pointed out that radiological examination is essential, since it dispel all doubts in nearly every case. Associations between the syndrome and peptic ulcer are relatively, and the joint surgical resolution of both forms is recommended.
