Abstract
We established two iPSC lines starting from skin fibroblasts of two healthy individuals using Sendai-virus-based technique. The obtained iPSCs were characterized showing same STR profile as starting fibroblasts, normal karyotype, loss of stemness vectors, expression of stemness markers, both through real-time PCR and immunofluorescence, (OCT4, SOX2, TRA-1-60, NANOG and SSEA4) and in vitro differentiation into three germ layers.

Abstract
In magnetically confined fusion experiments, laser interferometer/polarimeter systems allow one to determine plasma density, give valuable information on the internal magnetic fields, and contribute to the evaluation of the plasma magnetic equilibrium and to the real-time estimation of the q profile to allow feedback configuration control. This work presents an analysis of the interferometric and polarimetric signals of a multi-chord far-infrared interferometer/polarimeter for the divertor tokamak test facility, the new tokamak device currently under construction in Italy. The polarimetric signals are calculated both with approximate formulas and by solving the equation describing the evolution of the laser beam polarization inside the plasma using the Mueller formalism. The latter method correctly accounts for crosstalk between Faraday rotation and the Cotton-Mouton effect. The impact of the plasma birefringence on the interferometric phase shift is also studied, and it is found that a perturbation of the interferometric phase shift is present also in the case of an initial fixed linear polarization of the probe laser beam.

Abstract
PURPOSE To assess corneal tissue modifications after riboflavin-UVA-induced cross-linking of corneal collagen in patients with progressive keratoconus as well as regeneration of epithelium and subepithelial nerve plexus by in vivo HRT II system confocal microscopy in humans. METHODS Ten patients with progressive keratoconus were treated by riboflavin-UVA-induced cross-linking of corneal collagen, involving assessment of ultrastructural modifications of the corneal epithelium and subepithelial nerve plexus by HRT II system confocal microscopy. Treatment included instillation of 0.1% riboflavin-20% dextrane solution 5 minutes before UVA irradiation and every 5 minutes for a total of 30 minutes. Radiant energy was 3 mW/cm 2 or 5.4 Joule/cm 2 and the source was dual UVA (370 nm) light-emitting LED. The protocol included the operation followed by antibiotic medication and eye dressing with a soft therapeutic contact lens. Changes in epithelium and subepithelial and stromal nerve plexus were assessed by HRT II system confocal microscopy in vivo. RESULTS After 5 days of soft contact lens wearing, corneal epithelium has a regular morphology and density. Disappearance of subepithelial stromal nerve fibers was observed in the central irradiated area where, 1 month after the operation, initial reinnervation was microscopically observed. No changes in nerve fibers were observed in the peripheral untreated with a clear lateral transition between the two areas. Six months after the operation, the anterior subepithelial stroma was recolonized by nerve fibers with restoration of corneal sensitivity. CONCLUSIONS HRT II system confocal microscopy confirms corneal epithelium restore and re-innervation after riboflavin-UVA-induced collagen cross-linking directly in vivo in humans.

Abstract
BACKGROUND The assessment of efficiency of hearing protection devices (HPDs), conducted above statutory limits, must be made using a standardized method while devices are worn; however, standardized and suitable laboratory conditions are difficult to encounter at the workplace. To overcome this problem, there are methods of measurement at the workplace such as "field-microphone-in-real-ear" (F-MIRE). OBJECTIVES The study was concerned with the measurement of real noise attenuation using earplugs and a new evaluation system: we checked the difference between "real" attenuation (at workplace) and "theorical" attenuation (reproduced in the laboratory) as stated by the manufacturer. METHODS We used the E-A-Rfit computerized method, which measures the loss of attenuation of earplugs in the ear, calculating the difference of sound pressure between an "outside" microphone and an "inside" one, in relation to the same earplug. The measurements at the workplace were carried out on eight subjects with good hearing levels (aged between 20 and 25 years), who were trained to wear the devices correctly. After the tests carried out with the E-A-Rfit system, which does not require a subjective answer, we obtained graphs and tables showing real noise attenuation. RESULTS/CONCLUSIONS We propose a comparison between hearing threshold for frequency, personal attenuation rating (PAR) and single number rating (SNR, provided by manufacturer): a difference of 10 dB (PAR 27 db vs. SNR 37 dB) was clearly evident although dissimilar methods were used to obtain such values. The instrument is rapid, simple and objective to use and also allows personalized information and training for every worker.

Abstract
The non-intrusive density measurement of the thin plasma produced by a mini-helicon space thruster (HPH.com project) is a challenge, due to the broad density range (between 10(16) m(-3) and 10(19) m(-3)) and the small size of the plasma source (2 cm of diameter). A microwave interferometer has been developed for this purpose. Due to the small size of plasma, the probing beam wavelength must be small (λ = 4 mm), thus a very high sensitivity interferometer is required in order to observe the lower density values. A low noise digital phase detector with a phase noise of 0.02° has been used, corresponding to a density of 0.5 × 10(16) m(-3).

Abstract
Our study has examined the valuation of exposure to dust, noise and hand-arm vibrations (HAVs) during "extra-professional" activities of do-it-yourself, like wood smoothing, considering a group of 8 heterogeneous volunteer subjects (not expert of the sector), to find any kind of variability among the subjects. The results have shown a moderate risk for dust exposure and a realer one for HAVs, also higher noise exposure levels when an aspiration system is added to the sander. It's important that the exposure time considered in this study is not comparable to professional time exposure, cause of the "domestic" feature of this activities. Moreover, data could be influenced by different use conditions, grip and material grounds. It's also significant that there are not controls, formation and information of the subjects about the health risks, as well as ipersusceptibility.

Abstract
AIMS Collagen crosslinking treatment of progressive keratoconus using the photosensitiser riboflavin and ultraviolet A light of 370 nm wavelength has been shown to increase significantly the tensile strength of corneal collagen by about 300%. In keratoconus, interlamellar and interfibrillar slippage have been proposed as pathogenetic mechanisms. Therefore, the aim of this study was to assess the impact of collagen crosslinking on the interlamellar cohesive force. METHODS 72 post mortem porcine eyes were divided into six different treatment groups: the untreated control group, the standard crosslinking group, the hypo-osmolar crosslinking group, the stromal swelling group, the formaldehyde group and the α-amylase group. An anterior 9×4 mm strip of 400 μm thickness was prepared using a lamellar rotating microkeratome. For interlamellar cohesive force measurements a splitting plane was created at 50% depth. Force-distance profiles were recorded using a microcomputer-controlled biomaterial testing machine. RESULTS The mean interlamellar cohesive force was 0.24 N/mm in the untreated control group, 0.26 N/mm in the standard crosslinking group, 0.25 N/mm in the hypo-osmolar crosslinking group, 0.23 N/mm in hydrated corneas, 0.27 N/mm in the formaldehyde group without statistically significant difference. Only the values of the α-amylase group were statistically significantly lowered by 31.5% to 0.16 N/mm. CONCLUSIONS Surprisingly, corneal crosslinking does not increase the interlamellar cohesive force. In the α-amylase group the cohesive force was mainly decreased because of the digestion of proteoglycans. Crosslinking seems to stabilise only inter- and intrafibrillar, but not interlamellar cohesion.

Abstract
The case of a superior vena cava syndrome due to a central venous catheter thrombosis occurring in a second renal transplant patient is described. Imaging revealed thrombosis of the right internal jugular vein with extension along the confluence of the brachiocephalic veins and partial obstruction of the superior vena cava. Anticoagulant therapy with subcutaneous low-molecular-weight heparin was followed by warfarin administration. Despite adequate treatment, the symptomatology worsened because of thrombus organization. A workup revealed a complex prothrombotic underlying condition. Cardiothoracic surgeons were consulted, and an operative reconstruction of the superior vena cava using spiral vein bypass grafting was performed. In this report we describe the clinical presentation, diagnosis, and treatment of this case, with an emphasis on the role of thrombophilia.

Abstract
The paper presents a study of Faraday rotation (FR) angle and Cotton–Mouton (CM) phase shift measurements to determine their mutual interaction and the validity of the linear models presently used in equilibrium codes. Comparison between time traces of measurements and model calculations leads to the result that only an exact numerical solution of Stokes equations can reproduce in all the experimental data. As a consequence, approximated linear models can be applied only in a limited range of plasma parameters. In general, the nonlinear coupling between FR and CM is important for the evaluation of polarimetry parameters.

Abstract
PURPOSE We describe 8 cases of late spontaneous in-the-bag intraocular lens (IOL) luxation into the vitreous cavity, which occurred at the Department of Ophthalmology and Neurosurgery of the University of Siena between January and December 2006. METHODS In this interventional case series, the medical records of all patients with posterior luxation of in-the-bag IOLs - who had undergone a pars plana vitrectomy with IOL removal and scleral fixation IOL implantation between January and December 2007 at the Department of Ophthalmology and Neurosurgery of Siena, Italy - were retrospectively reviewed. RESULTS The final post- operative visual acuity was 20/30 or better in 6 patients, while myopic macular degeneration and total retinal detachment limited visual acuity in the remaining 2 patients. CONCLUSION The high prevalence of pseudoexfoliation (PEX) in the patients who had been operated for cataract phacoemulsification in our department could explain the occurrence of 8 posterior luxations of in-the-bag IOLs in only 1 year. Our study suggests that for the next years we will expect an increase in occurrence of spontaneous in-the- bag IOL luxations in the vitreous cavity. This condition could represent the last stage of PEX syndrome.

Abstract
The survival and function of a kidney transplant are influenced by numerous immunological and nonimmunological factors. The aim of this study was to evaluate the role of a number of cadaveric donor parameters on transplanted kidney function, and in particular on the occurrence of delayed graft function (DGF) since DGF is one of the most important factors in long-term organ survival. This study looked at 143 patients who underwent kidney transplant of whom 32 displayed DGF. The creatinine levels in organ recipients, which were evaluated during a follow-up that ranged between 6 months and 4 years, were significantly higher among recipients who developed DGF after transplant (1.8 +/- 0.7 vs 1.4 +/- 0.4; P = .02). The following donor parameters were taken into consideration: history of diabetes and hypertension; creatinine levels; inotropie therapy; problems relating to hemodynamics (hypotension and/or cardiac arrest); and cold ischemia time. We observed that a donor history of hypertension (46.8% DGF vs 23.27% no DGF; P = .01) and high levels of donor creatinine prior to organ removal (1.9 +/- 1.2 mg/dL DGF vs 1.2 +/- 0.9 mg/dL no DGF; P = .007) were significant risk factors for DGF among kidney recipients. No significant differences were found for others factors between recipients with versus without DGF.

Abstract
AIM In the therapy of primary hyperparathyroidism, the first surgical intervention, if efficacious, can remarkably reduce the incidence of persistence and relapses which are approximately about 5%. At present, the surgical approach of choice should involve the bilateral exploration of the neck. METHODS In the light of the high sensibility (91%) and specificity (98.8%) in the localization of parathyroid adenomas obtained by the parathyroid 99mTc-MIBI scintigraphy, we submitted, prospective and at random, between January 2001 and July 2004, 69 patients with primary hyperparathyroidism, to a conventional surgical treatment (bilateral exploration of the neck: 35 patients) or minimally-invasive approach (minimally invasive radioguided parathyroidectomy: 34 patients). This method consists of the injection of 50 mCi of 99mTc Sestamibi 2 h before the operation and the execution of parathyroid scintigraphy. When the adenoma is evident, we perform an incision of about 4 cm in the neck, 2 cm over the jugulum and the surgical dissection is guided by a probe showing the emission of gamma rays. RESULTS The parameters considered in order to compare the 2 groups, i.e. operating time, hospital stay and time of recovery were reduced in a significant way in the group submitted to the minimally invasive radioguided parathyroidectomy (MIRP). There were no complications in the 2 groups. In the follow-up we did not observe cases of persistence or relapses. CONCLUSIONS Therefore, we can confirm that the minimally invasive radioguided parathyroidectomy is a safe and efficacious method as well as the bilateral exploration of the neck. Moreover, cost reduction may convince many surgeons to consider MIRP the <<gold standard>> in the management of primary hyperparathyroidism.

Abstract
BACKGROUND Silicone gel and silicone occlusive sheeting are widely used at present for the treatment of hypertrophic and keloid scars. In recent studies the possibility was raised that static electricity generated by friction activated silicone sheeting could be the reason for this effect, and that it can, with time, cause involution of hypertrophic and keloid scars. Objective of this study was to test this hypothesis and to observe weather a continuous and also an increased negatively charged static electric field will shorten the treatment period. A silicone cushion was developed with the purpose of increasing a negative static-electric charge to accelerate the regression process. METHODS From November 2001 to June 2002 we studied in a prospective randomized study, 72 patients with hypertrophic an keloid scars. The trial extended over a 8-month period. 37 patients underwent silicone occlusive sheeting, the remaining 35 patients underwent silicone cushion (Clinicel). RESULTS Treatment with the silicone cushions yielded 74,2% cessation of itching and burning followed by pallor and flattening of the scar, some markedly so, over a few weeks to 5 months period. Additional 25,7% had their scars resolved in up to 8 months of treatment. Four patients (11,4%) who add recalcitrant scars with little response to the use of the silicone cushion were given intralesional corticosteroid injections, in addiction to the use of the cushion, resulting in a fairly rayed resolution of these scars over a period of 2 months. Treatment with the silicone occlusive sheeting yielded 52,3% itching and burning cessation followed by pallor and flattening of the scar, some markedly so, over a few weeks to 5 months period. Additional 22,1% had their scars resolved in up to 8 months of treatment. In conclusion by comparing the results of this trial using silicone cushions for the treatment of hypertrophic and keloid scars with those obtained using silicone gel or occlusive sheeting, a much faster response was demonstrated.

Abstract
BACKGROUND/AIMS Interleukin-6 (IL-6), a multifunctional cytokine, is expressed by various cells after many stimuli. This cytokine release is related, among other things, to the extent of the surgically-induced trauma. Laparoscopic cholecystectomy (LC) is a so-called "mini-invasive" surgical procedure and, on the basis of this consideration, the aim of the present prospective non-randomized study, is to examine (a) whether the IL-6 is modified and how, in patients after LC compared to patients undergoing open cholecystectomy (OC), (b) whether these findings are indicative of an increased risk to develop infectious complications and whether they are therefore clinically significant. METHODOLOGY Circulating IL-6 level was measured using a random access chemiluminescense-immunoassay system in 71 patients before the operation (time 0) and 1, 2, 3, 6, 24 and 48 hours after the beginning of the operation. Thirty-five patients underwent OC and 36 LC. RESULTS The increase in the serum IL-6 during LC was found to be significantly smaller than that during OC and resulted in a smaller extent of postoperative elevations for C-reactive protein. We recorded three cases (8.5%) of postoperative infections in the "open" group and IL-6 concentration normalized only 6 days after surgery. CONCLUSIONS An increase in the serum IL-6 level during LC is lower in comparison to OC and results in lower postoperative elevation in C-reactive protein. Laparoscopic surgery, associated with a small skin incision and the avoidance of open laparotomy, can thus minimize surgical stress, and provide more favorable postoperative conditions for patients. Indeed excessive and prolonged post-injury elevations are associated with increased morbidity.

Abstract
BACKGROUND It has long been known that a hypercoagulability state develops after surgery. A surge in circulating cytokine levels is also commonly found in the postoperative period. These cytokines have all been shown to be capable of inducing a hypercoagulability state. Recently laparoscopic cholecystectomy (LC) has been introduced, and its advantages over the open procedure seem related to the reduced surgical trauma. LC is associated with a diminished acute-phase response compared with the open procedure. Our present knowledge on the influence of laparoscopic upon coagulation and fibrinolysis is incomplete and based on a few studies. METHODS The aim of this prospective, nonrandomized study was to investigate hemostatic system alterations in patients who undergo open and laparoscopic cholecystectomy. In addition we also measured the plasma cytokine profile to explore any relationship between changes in plasma cytokine levels and postoperative coagulation profile. Between September 1999 and April 2002, 71 patients were nonrandomly assigned to open (group 1) or laparoscopic cholecystectomy (group 2). All patients from group 1 were operated by a surgical team different from ours, who prefers the OC procedure. The patients with acute cholecystitis were excluded. Prothrombin fragment 1.2 (F1.2), thrombin-antithrombin (TAT), fibrinogen, soluble fibrin, antithrombin III (AT), protein C, plasminogen, and D-dimer levels were measured at baseline and at 1, 24, 48, and 72 h postoperatively. Serial serum levels of IL-1beta and IL-6 were measured by colorimetric enzyme-linked immunosorbent assay (ELISA). RESULTS Plasma levels of F1.2, TAT, fibrinogen, soluble fibrin, and D-dimer increased significantly in group 1. Plasma levels of AT, protein C, and plasminogen decreased in both groups. In the OC group, the serum IL-3 and IL-6 levels began to significantly increased as early as 1 h from the beginning of the operation, revealing a peak at the sixth hour. When IL-6 and IL-1 levels were markedly elevated also, F1.2, fibrinogen, and soluble fibrin levels were increased. CONCLUSIONS Only mild hypercoagulability was observed in patients who had undergone laparoscopic cholecystectomy. The cytokine surge was correlated with hypercoagulability. There was in fact a positive correlation between IL-6 level and hypercoagulability. The correlation between cytokine levels and coagulation activation may be related to the type of surgery performed. Further studies are required to investigate these issues.

Abstract
Of 54 patients, we reviewed 26 with 28 operations for hallux valgus according to the Viladot-Regnauld technique. Follow-up was 18.7 (12-26) years. In 26 operations, the score according to Kitaoka and modified by Calder was excellent or good, and in two, fair. There were no complications. Average valgus angle correction was 15 degrees (8 degrees-29 degrees) and average intermetatarsal angle correction was 7 degrees (4 degrees-12 degrees). Sesamoids were medialised, on average, by at least 25% compared to the pre-operative situation. The results confirm the validity of this surgical procedure.

Abstract
Changes of hemocoagulability and of plasmatic fibrinolysis have induced us to study PHA following the administration of the lipid load. We have studied the effects induced by the administration of a lipid load, constituted by 1/2 g of olive oil and by 1/2 g of butter dissolved in 200 ml of vaccine milk. PHA has been estimated in all our subjects under basal conditions and after 4 1/2 hours from the lipid load. The statistical analysis of the results we have obtained shows a significant PHA reduction following the lipid load. Concluding, our results indicates that the lipid load very frequently causes a reduction of PHA which is due to a consumption of heparin. This consumption is more probably due to the activation of lipoprotein-lipase by heparin.
