Abstract
OBJECTIVE Lichen sclerosus is a chronic, inflammatory, progressive skin disease predominantly affecting anogenital areas. Vulvar lichen sclerosus (VLS) is one of the most common conditions treated in vulvar clinics; most patients report distressing symptoms of itching, burning, stinging, and pain (particularly during or after sexual intercourse). A preliminary, prospective, single-center study was performed to investigate the efficacy of hyaluronan hybrid cooperative complex (HCC) comprising high and low molecular weight hyaluronic acid to treat menopausal women with VLS. PATIENTS AND METHODS Patients (N = 30) received two HCC injections at 32 mg/ml (one month apart). At baseline and one and six months after treatment, patients completed validated psychometric questionnaires to assess their self-reported pain, itching, and dryness using the Visual Analogue Scale (VAS) and sexual function by the Female Sexual Function Index (FSFI). RESULTS After treatment with HCC, no side effects or complications were reported. VAS scores showed a trend towards reduced pain and itching intensity, and there was a statistically significant reduction in median VAS score for dryness at follow-up vs. baseline (p=0.038). For sexual function, there was a statistically significant improvement in lubrication (p=0.001) and orgasm (p=0.001) FSFI domains. CONCLUSIONS Overall, this preliminary study demonstrated the promising efficacy of HCC in menopausal women with VLS without side effects.

Abstract
Microbial electrosynthesis (MES) is a promising carbon utilization technology, but the low-value products (i.e., acetate or methane) and the high electric power demand hinder its industrial adoption. In this study, electrically efficient MES cells with a low ohmic resistance of 15.7 mΩ m2 were operated galvanostatically in fed-batch mode, alternating periods of high CO2 and H2 availability. This promoted acetic acid and ethanol production, ultimately triggering selective (78% on a carbon basis) butyric acid production via chain elongation. An average production rate of 14.5 g m-2 d-1 was obtained at an applied current of 1.0 or 1.5 mA cm-2, being Megasphaera sp. the key chain elongating player. Inoculating a second cell with the catholyte containing the enriched community resulted in butyric acid production at the same rate as the previous cell, but the lag phase was reduced by 82%. Furthermore, interrupting the CO2 feeding and setting a constant pH2 of 1.7-1.8 atm in the cathode compartment triggered solventogenic butanol production at a pH below 4.8. The efficient cell design resulted in average cell voltages of 2.6-2.8 V and a remarkably low electric energy requirement of 34.6 kWhel kg-1 of butyric acid produced, despite coulombic efficiencies being restricted to 45% due to the cross-over of O2 and H2 through the membrane. In conclusion, this study revealed the optimal operating conditions to achieve energy-efficient butyric acid production from CO2 and suggested a strategy to further upgrade it to valuable butanol.

Abstract
Electrospinning has been demonstrated as a very promising method to create bipolar membranes (BPMs), especially as it allows three-dimensional (3D) junctions of entangled anion exchange and cation exchange nanofibers. These newly developed BPMs are relevant to demanding applications, including acid and base production, fuel cells, flow batteries, ammonia removal, concentration of carbon dioxide, and hydrogen generation. However, these applications require the introduction of catalysts into the BPM to allow accelerated water dissociation, and this remains a challenge. Here, we demonstrate a versatile strategy to produce very efficient BPMs through a combined electrospinning-electrospraying approach. Moreover, this work applies the newly investigated water dissociation catalyst of nanostructured silica MCM-41. Several BPMs were produced by electrospraying MCM-41 nanoparticles into the layers directly adjacent to the main BPM 3D junction. BPMs with various loadings of MCM-41 nanoparticles and BPMs with different catalyst positions relative to the junction were investigated. The membranes were carefully characterized for their structure and performance. Interestingly, the water dissociation performance of BPMs showed a clear optimal MCM-41 loading where the performance outpaced that of a commercial BPM, recording a transmembrane voltage of approximately 1.11 V at 1000 A/m2. Such an excellent performance is very relevant to fuel cell and flow battery applications, but our results also shed light on the exact function of the catalyst in this mode of operation. Overall, we demonstrate clearly that introducing a novel BPM architecture through a novel hybrid electrospinning-electrospraying method allows the uptake of promising new catalysts (i.e., MCM-41) and the production of very relevant BPMs.

Abstract
Bipolar membranes (BPMs), a special class of ion exchange membranes with the unique ability to electrochemically induce either water dissociation or recombination, are of growing interest for environmental applications including eliminating chemical dosage for pH adjustment, resource recovery, valorization of brines, and carbon capture. However, ion transport within BPMs, and particularly at its junction, has remained poorly understood. This work aims to theoretically and experimentally investigate ion transport in BPMs under both reverse and forward bias operation modes, taking into account the production or recombination of H+ and OH-, as well as the transport of salt ions (e.g., Na+, Cl-) inside the membrane. We adopt a model based on the Nernst-Planck theory, that requires only three input parameters─membrane thickness, its charge density, and pK of proton adsorption─to predict the concentration profiles of four ions (H+, OH-, Na+, and Cl-) inside the membrane and the resulting current-voltage curve. The model can predict most of the experimental results measured with a commercial BPM, including the observation of limiting and overlimiting currents, which emerge due to particular concentration profiles that develop inside the BPM. This work provides new insights into the physical phenomena in BPMs and helps identify optimal operating conditions for future environmental applications.

Abstract
The use of electrospun bipolar membranes (BPMs) with an interfacial three-dimensional (3D) junction of entangled nano-/microfibers has been recently proposed as a promising fabrication strategy to develop high-performance BPMs. In these BPMs, the morphology and physical properties of the 3D junction are of utmost importance to maximize the membrane performance. However, a full understanding of the impact of the junction thickness on the membrane performance is still lacking. In this study, we have developed bipolar membranes with the same composition, only varying the 3D junction thicknesses, by regulating the electrospinning time used to deposit the nano-/microfibers at the junction. In total, four BPMs with 3D junction thicknesses of ∼4, 8, 17, and 35 μm were produced to examine the influence of the junction thickness on the membrane performance. Current-voltage curves for water dissociation of BPMs exhibited lower voltages for BPMs with thicker 3D junctions, as a result of a three-dimensional increase in the interfacial contact area between cation- and anion-exchange fibers and thus a larger water dissociation reaction area. Indeed, increasing the BPM thickness from 4 to 35 μm lowered the BPM water dissociation overpotential by 32%, with a current efficiency toward HCl/NaOH generation higher than 90%. Finally, comparing BPM performance during the water association operation revealed a substantial reduction in the voltage from levels of its supplied open circuit voltage (OCV), owing to excessive hydroxide ion (OH-) and proton (H+) leakage through the relevant layers. Overall, this work provides insights into the role of the junction thickness on electrospun BPM performance as a crucial step toward the development of membranes with optimal entangled junctions.

Abstract
Agricultural development, extensive industrialization, and rapid growth of the global population have inadvertently been accompanied by environmental pollution. Water pollution is exacerbated by the decreasing ability of traditional treatment methods to comply with tightening environmental standards. This review provides a comprehensive description of the principles and applications of electrochemical methods for water purification, ion separations, and energy conversion. Electrochemical methods have attractive features such as compact size, chemical selectivity, broad applicability, and reduced generation of secondary waste. Perhaps the greatest advantage of electrochemical methods, however, is that they remove contaminants directly from the water, while other technologies extract the water from the contaminants, which enables efficient removal of trace pollutants. The review begins with an overview of conventional electrochemical methods, which drive chemical or physical transformations via Faradaic reactions at electrodes, and proceeds to a detailed examination of the two primary mechanisms by which contaminants are separated in nondestructive electrochemical processes, namely electrokinetics and electrosorption. In these sections, special attention is given to emerging methods, such as shock electrodialysis and Faradaic electrosorption. Given the importance of generating clean, renewable energy, which may sometimes be combined with water purification, the review also discusses inverse methods of electrochemical energy conversion based on reverse electrosorption, electrowetting, and electrokinetic phenomena. The review concludes with a discussion of technology comparisons, remaining challenges, and potential innovations for the field such as process intensification and technoeconomic optimization.

Abstract
Direct air capture (DAC) aims to remove CO2 directly from the atmosphere. In this study, we have demonstrated proof-of-concept of a DAC process combining CO2 adsorption in a packed bed of amine-functionalized anion exchange resins (AERs) with a pH swing regeneration using an electrochemical cell (EC). The resin bed was regenerated using the alkaline solution produced in the cathodic compartment of the EC, while high purity CO2 (>95%) was desorbed in the acidifying compartment. After regenerating the AERs, some alkaline solution remained on the surface of the resins and provided additional CO2 capture capacity during adsorption. The highest CO2 capture capacity measured was 1.76 mmol·g-1 dry resins. Moreover, as the whole process was operated at room temperature, the resins did not show any apparent degradation after 150 cycles of adsorption-desorption. Furthermore, when the relative humidity of the air source increased from 33 to 84%, the water loss of the process decreased by 63%, while CO2 capture capacity fell 22%. Finally, although the pressure drop of the adsorption column (5 ± 1 kPa) and the energy consumption of the EC (537 ± 33 kJ·mol-1 at 20 mA·cm-2) are high, we have discussed the potential improvements toward a successful upscaling.

Abstract
Background: To investigate the effects of the COVID-19 lockdowns on the vasculopathic population. Methods: The Divisions of Vascular Surgery of the southern Italian peninsula joined this multicenter retrospective study. Each received a 13-point questionnaire investigating the hospitalization rate of vascular patients in the first 11 months of the COVID-19 pandemic and in the preceding 11 months. Results: 27 out of 29 Centers were enrolled. April-December 2020 (7092 patients) vs. 2019 (9161 patients): post-EVAR surveillance, hospitalization for Rutherford category 3 peripheral arterial disease, and asymptomatic carotid stenosis revascularization significantly decreased (1484 (16.2%) vs. 1014 (14.3%), p = 0.0009; 1401 (15.29%) vs. 959 (13.52%), p = 0.0006; and 1558 (17.01%) vs. 934 (13.17%), p < 0.0001, respectively), while admissions for revascularization or major amputations for chronic limb-threatening ischemia and urgent revascularization for symptomatic carotid stenosis significantly increased (1204 (16.98%) vs. 1245 (13.59%), p < 0.0001; 355 (5.01%) vs. 358 (3.91%), p = 0.0007; and 153 (2.16%) vs. 140 (1.53%), p = 0.0009, respectively). Conclusions: The suspension of elective procedures during the COVID-19 pandemic caused a significant reduction in post-EVAR surveillance, and in the hospitalization of asymptomatic carotid stenosis revascularization and Rutherford 3 peripheral arterial disease. Consequentially, we observed a significant increase in admissions for urgent revascularization for symptomatic carotid stenosis, as well as for revascularization or major amputations for chronic limb-threatening ischemia.

Abstract
With the use of bipolar membranes (BPMs) in an expanding range of applications, there is an urgent need to understand and improve the catalytic performance of BPMs for water dissociation, as well as to increase their physical and chemical stability. In this regard, electrospinning BPMs with 2D and 3D junction structures have been suggested as a promising route to produce high-performance BPMs. In this work, we investigate the effect of entangling anion and cation exchange nanofibers at the junction of bipolar membranes on the water dissociation rate. In particular, we compare the performance of different tailor-made BPMs with a laminated 2D junction and a 3D electrospun entangled junction, while using the same type of anion and cation exchange polymers in a single/dual continuous electrospinning manufacturing method. The bipolar membrane with a 3D entangled junction shows an enhanced water dissociation rate as compared to the bipolar membrane with laminated 2D junction, as measured by the decreased bipolar membrane potential. Moreover, we investigate the use of a third polymer, that is, poly(4-vinylpyrrolidine) (P4VP), as a catalyst for water dissociation. This polymer confirmed that a 3D entangled junction BPM (with incorporated P4VP) gives a higher water dissociation rate than does a 2D laminated junction BPM with P4VP as the water dissociation catalyst. This work demonstrates that the entanglement of the anion exchange polymer with P4VP as the water dissociation catalyst in a 3D junction is promising to develop bipolar membranes with enhanced performance as compared to the conventionally laminated membranes.

Abstract
BACKGROUND Lichen sclerosus is a chronic relapsing inflammatory dermatosis with a predilection for anogenital skin in 85%-98% of cases and is more prevalent in women (3%) than in men (> 0.07%). OBJECTIVES The purpose of this study was to investigate gender differences in clinical presentation and therapeutic response to treatment with platelet-rich plasma (PRP), an emerging innovative strategy for LS. METHODS Forty-three male and 51 female patients affected by LS were evaluated. Each patient was subjected to PRP treatment (1 infiltration every 15 days, for 3 times). RESULTS The PRP procedure was well tolerated by all patients and an overall significant decrease in symptoms was reported 6 months after PRP infiltration. Reduction in pain and burning sensation was significant in both gender but more accentuated in women than in men, whereas reduction of itching was similar. On the contrary, dyspareunia evidenced sex-related difference since a significant diminution was observed only in male. CONCLUSIONS This study demonstrates that PRP based therapy may exert a relevant role in LS patient management due to its effect on Quality of Life (QoL) and sexual function in both gender. In addition, the study underlined gender-related differences in severity of symptoms and disease age onset.

Abstract
Decarbonisation of the economy has become a priority at the global level, and the resulting legislative pressure is pushing the chemical and energy industries away from fossil fuels. Microbial electrosynthesis (MES) has emerged as a promising technology to promote this transition, which will further benefit from the decreasing cost of renewable energy. However, several technological challenges need to be addressed before the MES technology can reach its maturity. The aim of this review is to critically discuss the bottlenecks hampering the industrial adoption of MES, considering the whole production process (from the CO2 source to the marketable products), and indicate future directions. A flexible stack design, with flat or tubular MES modules and direct CO2 supply, is required for site-specific decentralised applications. The experience gained for scaling-up electrochemical cells (e.g. electrolysers) can serve as a guideline for realising pilot MES stacks to be technologically and economically evaluated in industrially relevant conditions. Maximising CO2 abatement rate by targeting high-rate production of acetate can promote adoption of MES technology in the short term. However, the development of a replicable and robust strategy for production and in-line extraction of higher-value products (e.g. caproic acid and hexanol) at the cathode, and meaningful exploitation of the currently overlooked anodic reactions, can further boost MES cost-effectiveness. Furthermore, the use of energy storage and smart electronics can alleviate the fluctuations of renewable energy supply. Despite the unresolved challenges, the flexible MES technology can be applied to decarbonise flue gas from different sources, to upgrade industrial and wastewater treatment plants, and to produce a wide array of green and sustainable chemicals. The combination of these benefits can support the industrial adoption of MES over competing technologies.

Abstract
CO2 capture from the atmosphere (or direct air capture) is widely recognized as a promising solution to reach negative emissions, and technologies using alkaline solutions as absorbent have already been demonstrated on a full scale. In the conventional temperature swing process, the subsequent regeneration of the alkaline solution is highly energy-demanding. In this study, we experimentally demonstrate simultaneous solvent regeneration and CO2 desorption in a continuous system using a H2-recycling electrochemical cell. A pH gradient is created in the electrochemical cell so that CO2 is desorbed at a low pH, while an alkaline capture solution (NaOH) is regenerated at high pH. By testing the cell under different working conditions, we experimentally achieved CO2 desorption with an energy consumption of 374 kJ·mol-1 CO2 and a CO2 purity higher than 95%. Moreover, our theoretical calculations show that a minimum energy consumption of 164 kJ·mol-1 CO2 could be achieved. Overall, the H2-recycling electrochemical cell allowed us to accomplish the simultaneous desorption of high-purity CO2 stream and regeneration of up to 59% of the CO2 capture capacity of the absorbent. These results are promising toward the upscaling of an energy-effective process for direct air capture.

Abstract
This paper describes the experimental campaign carried out with a reverse electrodialysis (RED) demonstration plant (Marsala, Italy) with the main aims of: (i) evaluating the effect of various operating parameters, including the redox processes, on the system performances; (ii) using the plant for the simultaneous generation of electric energy and treatment of wastewater. The prototype (44 × 44 cm2, 500 cell pairs) was tested using both real (brackish water and brine) and artificial solutions. Tests with two different electrode rinse solutions (with or without iron redox couples) were performed. In agreement with the data obtained in the laboratory, the presence of iron ions contributes positively to the power production. The effect of flow rates in the electrode and saline compartments, as well as aging of the electrode rinse solution was also investigated. The possibility to remove an organic pollutant (the azoic dye Acid Orange 7) from the electrode solution was tested, obtaining a very fast and total removal of the pollutant. This experimental campaign represents the first demonstration in a real environment of the abilities of a RED plant to treat wastewater, thus giving useful indications for the spreading of RED technology in the near future.

Abstract
Large-scale atmospheric circulation controls the mass and energy balance of the Greenland ice sheet through its impact on radiative budget, runoff and accumulation. Here, using reanalysis data and the outputs of a regional climate model, we show that the persistence of an exceptional atmospheric ridge, centred over the Arctic Ocean, was responsible for a poleward shift of runoff, albedo and surface temperature records over the Greenland during the summer of 2015. New records of monthly mean zonal winds at 500 hPa and of the maximum latitude of ridge peaks of the 5,700±50 m isohypse over the Arctic were associated with the formation and persistency of a cutoff high. The unprecedented (1948–2015) and sustained atmospheric conditions promoted enhanced runoff, increased the surface temperatures and decreased the albedo in northern Greenland, while inhibiting melting in the south, where new melting records were set over the past decade. Atmospheric circulation controls the mass and energy balance of the Greenland ice sheet, yet the exact dynamics remain unknown. Here, the authors show that record conditions over Greenland during the summer of 2015 were associated with the formation and persistency of an Arctic cut-off high.

Abstract
AIM Cardiovascular disease is a leading cause of morbidity and mortality in end-stage renal disease (ESRD) patients on maintenance hemodialysis (HD). Neither traditional nor emerging risk factors for cardiovascular disease can explain completely this excess of morbidity and mortality and the role and timing of primary prevention strategies in this population has not been clarified. The aim of this study was to assess if an aggressive pharmacological preventive treatment may reduce the myocardial ischemic burden and then improve the cardiovascular outcome In ESRD patients. METHODS Forty-three asymptomatic ESRD patients on maintenance HD were evaluated. Asymptomatic patients with neither history nor clinical evidence of cardiovascular disease were considered. A total of 31 ESRD patients were enrolled into the study and were submitted to Tc-99m SESTAMIBI myocardial gated- single-photon emission computed tomography (SPECT) stress test. All patients then received an aggressive medical regimen with statins, antiplatelet drugs, ACE inhibitors (ACE-I) and/or Angiotensin II Receptor Blockers (ARB) and other hypotensive, glucose-lowering medications, sevelamer, calcium carbonate and calcitriol if required. RESULTS A significant reduction of coronary functional reserve was found in more than 50% of otherwise asymptomatic HD patients and may often be reverted by prolonged aggressive medical therapy. After a four-year follow-up under aggressive medical therapy no significant difference was observed neither in the incidence of conventional and emerging cardiovascular risk factors nor in cardiovascular outcome of patients with or without silent myocardial ischemia (SMI). CONCLUSION As cardiovascular disease (CVD) is by far the first cause of death in ESRD, an aggressive medical management may be highly advisable for the primary prevention of major adverse cardiac events in all HD patients despite the stress test evidence of inducible myocardial ischemia .

Abstract
In this work, we investigate the spontaneous bursting behaviour expressed by in vitro hippocampal networks by using a high-resolution CMOS-based microelectrode array (MEA), featuring 4096 electrodes, inter-electrode spacing of 21 µm and temporal resolution of 130 µs. In particular, we report an original development of an adapted analysis method enabling us to investigate spatial and temporal patterns of activity and the interplay between successive network bursts (NBs). We first defined and detected NBs, and then, we analysed the spatial and temporal behaviour of these events with an algorithm based on the centre of activity trajectory. We further refined the analysis by using a technique derived from statistical mechanics, capable of distinguishing the two main phases of NBs, i.e. (i) a propagating and (ii) a reverberating phase, and by classifying the trajectory patterns. Finally, this methodology was applied to signal representations based on spike detection, i.e. the instantaneous firing rate, and directly based on voltage-coded raw data, i.e. activity movies. Results highlight the potentialities of this approach to investigate fundamental issues on spontaneous neuronal dynamics and suggest the hypothesis that neurons operate in a sort of 'team' to the perpetuation of the transmission of the same information.

Abstract
The intact brain is continuously targeted by a wealth of stimuli with distinct spatio-temporal patterns which modify, since the very beginning of development, the activity and the connectivity of neuronal networks. In this paper, we used dissociated neuronal cultures coupled to microelectrode arrays (MEAs) to study the response of cortical neuron assemblies to low-frequency stimuli constantly delivered over weeks in vitro. We monitored the spontaneous activity of the cultures before and after the stimulation sessions, as well as their evoked response to the stimulus. During in vitro development, the vast majority of the cultures responded to the stimulation by significantly increasing the bursting activity and a widespread stabilization of electrical activity was observed after the third week of age. A similar trend was present between the spontaneous activity of the networks observed over 30 min after the stimulus and the responses evoked by the stimulus itself, although no significant differences in spontaneous activity were detected between stimulated and non-stimulated cultures belonging to the same preparations. The data indicate that the stimulation had a delayed effect modulating responsiveness capability of the network without directly affecting its intrinsic in vitro development.

Abstract
Cytomegalovirus (CMV) and BK polyomavirus (BKV) infections have been described in a high percentage of renal transplant patients and are known to cause various complications in renal transplantation. They are closely related to immunosuppressive therapy and implicated in the progression of graft failure. This review focuses on the clinical aspects of CMV and BKV infection after renal transplantation, optimal monitoring, and recent preventive measures and interventions to improve graft function and recipient survival.

Abstract
OBJECTIVES Cardiovascular disease (CVD) is the main cause of death among haemodialysis (HD) patients. Emerging cardiovascular risk factors such as oxidative stress and chronic inflammation are involved in these patients together with traditional risk factors. Here we investigate the effects of a short-term folate treatment on some markers of chronic inflammation in two groups of HD patients with and without vascular occlusive disease (VOD). PATIENTS AND METHODS Homocysteine (HCy), C-reactive protein (CRP), Folate, fibrinogen and alpha1 acid glycoprotein (alpha1AGP) were dosed before and after a 3-month course of high-dose folate (25 mg intravenous calcium laevofolinate pentahydride once weekly) and again after a one-month washout in 15 HD patients with established VOD (group A) and in 15 comparable HD patients with no diagnosis of VOD (group B). RESULTS Baseline HCy and CRP were significantly elevated in patients of both groups A and B compared to normal values. Folate treatment significantly reduced HCy in patients of both groups A and B and alpha1AGP only in patients of group A, while the other markers were not modified. After the one-month washout a significant raise of CRP could be observed in patients of group A; again, the other markers were not modified. CONCLUSIONS Our results suggest that significant reduction of serum HCy can be achieved in both patients with or without VOD after administration of high-dose folic acid. Hence, folic acid supply is useful in the treatment of hyperhomocysteinemia in HD patients, although it is not sufficient to modify their chronic inflammatory status.

Abstract
We report a case of a woman with vulvar melanoma, arisen from a plane melanocytic lesion, extended from clitoris to the left minor labium. After diagnostic biopsy, a preoperative lymphoscintigraphy with 99m-Tc nanocolloid was performed. Surgery consisted in a radical vulvectomy, radio-controlled lymphadenectomy and vulvar reconstruction by two bilateral subgluteus soft-tissue flaps, anastomosing the urethral and vaginal stumps. Five years follow-up was negative for neoplastic recurrence.

Abstract
Merkel cell carcinoma (MCC) is an aggressive cutaneous-neuroendocrine neoplasia with poor prognosis and high propensity for locoregional and distant metastasis. Lack of knowledge about its biological behavior, pathogenesis, and prognostic factors, complicates the prospective evaluation. Sentinel node dissection, concomitant with radical excision of the lesion, has increased in the last few years. The suitability of this technique is linked to the MCC high tendency to spread "in primis" at locoregional nodes such as other malignancies such as cutaneous melanoma. Aim of the study is the prospective evaluation of the sentinel node dissection and of the adjuvant therapies in 9 patients MCC affected. All patients, underwent evaluation and staging of the neoplasia. Diagnosis was made by excisional biopsy and histological examination. Sentinel node dissection was performed in patients without clinical locoregional metastases (8 cases). Patients with sentinel node positive for metastasis underwent radical lymphadenectomy (3 cases). One patient affected by clinically locoregional metastases had, at once, radical lymphadenectomy. Radiotherapy and/or chemotherapy as adjuvant therapy were implemented (4 cases).

Abstract
The case of a 54-year-old woman who developed vulvar melanoma arising from a melanocytic lesion, extending from the clitoris to the left labium minor, without clinical involvement of the groin node station bilaterally is presented. The patient first underwent an incisional diagnostic biopsy that revealed a melanoma 4 mm in thickness; subsequently preoperative lymphoscintigraphy with 99m Tc Nanocoll was executed. Surgery consisted of a radio-controlled lymphadenectomy and radical vulvectomy. Two bilateral subgluteus soft-tissue flaps were made to reconstruct the surgical defect, anastomosing the urethral and vaginal stump. At 36 months follow-up the patient was negative for neoplastic recurrence.

Reactive oxygen species formation and release of pro-inflammatory/pro-atherogenic cytokines, that is, interleukin 1-beta and tumor necrosis factor-alpha, need the activation of the arachidonic acid cascade via the enzyme 5-lipoxygenase (5-Lox). 5-Lox activity and expression are significantly increased in peripheral blood mononuclear cells (PBMCs) of end-stage renal disease (ESRD) patients on maintenance hemodialysis (HD). Diets enriched with n-3 polyunsaturated fatty acids (PUFAs) (omega-3) have been associated to a lower incidence of coronary heart disease (CHD) and a reduction in atherosclerotic lesions. Omega-3 may interfere with the arachidonic acid cascade by inhibiting 5-Lox. Lipid peroxidation, leukotriene B(4) (LTB(4)) production, 5-Lox activity and expression were investigated in PBMC isolated from ESRD patients under maintenance HD before and after a 3-month oral supplementation with omega-3 at a daily dose of 2700 mg of n-3 PUFAs at the average eicosapentaenoic acid/docosaesaenoic acid ratio of 1.2 and finally after a further 3-month washout with no omega-3 supplementation. PBMCs from non-uremic volunteers were also investigated for comparison to normal parameters. Administration of omega-3 reduced significantly lipid peroxidation (P < 0.0001), LTB(4) synthesis (P < 0.0001) and 5-Lox activity (P < 0.0001), with no effect on 5-Lox protein expression. After the 3-month washout, all parameters were comparable to those observed before treatment. Our results resemble those obtained after oral administration of vitamin E and are consistent with a reversible, dose-dependent inhibition of 5-Lox by omega-3. Upregulation of 5-Lox may also be related to the increased mitochondrial damage and apoptosis of PBMCs observed in ESRD patients compared to non-uremic controls. Omega-3 may thus protect PBMCs of ESRD patients against oxidative stress.

Abstract
Large evidence showing an association between depression and tobacco smoking is known. Nicotine is the active chemical responsible for smoking addiction, and its withdrawal may induce in smokers greater sensitivity to stress. Our aim has been to investigate the links between tobacco addiction and depression by studying the long-term effects of repeated administration of nicotine followed by dependence, to forced swimming test, serotonin content and 5-HT(1A) expression in diencephalon. Dependence has been induced by daily subcutaneous injection in mice of nicotine (2mg/kg four injections daily) for 15 days and assessed after nicotine withdrawal with an abstinence scale; control animals received daily subcutaneous injection of saline for the same period. Experiments on forced swimming test have been carried out at t=0 (last day of nicotine or saline treatment), and 15, 30, 45 and 60 days after saline or nicotine withdrawal. Both control mice and nicotine mice have been pre-treated with oral 5-hydroxy-tryptophan (12.5-50mg/kg), precursor of serotonin, before forced swimming test. Nicotine mice have shown on forced swimming test a significant increase of immobility time compared to control mice. This increase was not evident in nicotine mice treated with 5-hydroxy-tryptophan and treatment with the selective serotonin receptorial antagonist WAY 100635 (WAY) abolished 5-hydroxy-tryptophan effects. Evaluation of diencephalic serotonin, performed at t=0 showed an increase of diencephalic serotonin content, while serotonin measured 15, 30, 45 and 60 days after nicotine withdrawal, was significantly reduced in nicotine mice compared to control mice. Western blot analysis showed a great reduction of 5-HT(1A) receptor expression in nicotine mice measured at t=0 (last day of treatment) and at 15 and 30 days after nicotine withdrawal compared to control mice. Our results show that (i) behavioural alterations estimated with forced swimming test and (ii) changes in diencephalic serotonin content and 5-HT(1A) receptor expression, are present since nicotine is withdrawn even after a long time, suggesting a role of serotonin in mood disorders eventually occurring following smoking cessation.

Abstract
By taking advantages of the main features of the microelectrode array (MEA) technology (i.e. multisite recordings, stable and long-term coupling with the biological preparation), we analyzed the changes in activity patterns induced by applying specific substances to dissociated cortical neurons from rat-embryos (E18). Data were recorded simultaneously from 60 electrodes, and the electrophysiological behavior was investigated during the third week in vitro, both at the spike and burst level. The analysis of the electrophysiological activity modulation, by applying agonists of the ionotropic glutamate receptors at low (i.e. 0.2-1-5 microM) and high (i.e. 50-100 microM) concentrations, is presented. Preliminary results show that the dynamics of the in vitro cortical neurons is very sensitive to pharmacological manipulation of the glutamatergic transmission and the effects on the network behavior are strictly dependent from the drug concentration. In particular, the addition of a high-dose of agonist determined a global and irreversible depression of the network activity, while, in the low-concentration case, the electrophysiological behavior showed different results, depending on the type of receptor involved. From these observations, we are encouraged to think of a more engineered system, based on in vitro cortical neurons, as a novel sensitive system for drug (pre)-screening and neuropharmacological evaluations.

Abstract
PURPOSE To compare acute toxicity, tumor response, and sphincter preservation in three schedules of concurrent chemoradiation in resectable transmural and/or node-positive extraperitoneal rectal cancer. PATIENTS AND METHODS Between 1990 and 1999, 163 consecutive patients were treated according to the following combined modalities: FUMIR: between 1990 and 1995, 83 patients were treated with bolus i.v. mitomycin C (MMC), 10 mg/m(2) day 1, plus 24-h continuous infusion i.v. 5-fluorouracil (5-FU) 1,000 mg/m(2) days 1-4, and concurrent external beam radiotherapy (37.8 Gy). PLAFUR-4: between 1995 and 1998, 40 patients were treated with cisplatin (c-DDP) 60 mg/m(2) given as slow infusion (1-4 h) on days 1 and 29, plus 24-h continuous infusion i.v. 5-FU 1,000 mg/m(2), days 1-4 and 29-32 with concurrent external-beam radiotherapy (50.4 Gy). PLAFUR-5: between 1998 and 1999, 40 patients were treated with c-DDP 60 mg/m(2) given as slow infusion (during 1-4 h) on days 1 and 29, plus 24-h continuous infusion i.v. 5-FU 1,000 mg/m(2), days 1-5 and 29-33 with concurrent external-beam radiotherapy (50.4 Gy). RESULTS Grade > or = 3 acute toxicity occurred in 14%, 5%, and 17% of patients treated in the FUMIR, PLAFUR-4, and PLAFUR-5 studies, respectively (p = 0.201). In the FUMIR, PLAFUR-4, and PLAFUR-5 studies, clinical response rate was 77%, 70%, and 83%, respectively. Tumor downstaging occurred in 57%, 68%, and 58% of patients, respectively. Pathologic complete response was recorded in 9% (FUMIR), 23% (PLAFUR-4), and 20% (PLAFUR-5) of patients. Sphincter-preserving surgery was feasible in 44% (FUMIR), 40% (PLAFUR-4), and 61% (PLAFUR-5) of patients having a distance between the anal-rectal ring and the lower pole of the tumor of 0-30 mm, and in 95%, 100%, and 100%, respectively, in those having a distance of 31-50 mm. Comparing FUMIR vs. PLAFUR, the clinical response rate was similar in the two series: a partial response was observed in 62/81 (77%) patients with FUMIR treatment, and in 61/80 (76%) patients with PLAFUR treatment. Tumor downstaging was observed in 46/81 (57%) patients and in 50/80 (68%) patients, respectively. The pathologic complete response rate was statistically higher in the PLAFUR series: 7/81 (9%) patients with FUMIR treatment and 17/80 (21%) patients with PLAFUR treatment (p = 0.04). Major downstaging (pT0+ pTmic+ pT1) in the FUMIR group was reported in 12/81 (15%) patients versus 31/80 (39%) patients in the PLAFUR group (p = 0.0006). The anal sphincter was preserved in 63/81 (78%) patients with FUMIR treatment and in 69/80 (86%) patients with PLAFUR treatment. The perioperative morbidity was statistically lower with PLAFUR: a perioperative morbidity was experienced by 20/81 (25%) patients with FUMIR treatment and by 9/80 (11%) patients with PLAFUR treatment (p = 0.042). CONCLUSION In our experience, higher radiation dose (50.4 Gy vs. 37.8 Gy), a second course of concurrent 5-FU, and the use of c-DDP instead of MMC improved the pathologic response rate without increasing acute toxicity and perioperative morbidity. The use of 5-FU 5-day infusion (PLAFUR-5) resulted in higher toxicity with a similar response rate compared to 4-day infusion (PLAFUR-4).

Abstract
BACKGROUND To evaluate the impact of automated Protamine Dose Assay (PDA) performed with Hemochron 8000 (International Technodyne Company, Edison, NJ) on the management of heparin reversal after cardiopulmonary bypass (CPB). PDA was compared with empirical protamine to heparin ratio with regard to calculation of the protamine dose, and the sensitivity of PDA and ACT to residual circulating heparin after protamine administration was investigated too. METHODS DESIGN prospective and randomized study. SETTING cardiac surgical center of a General Hospital. PARTICIPANTS 50 patients undergoing elective cardiac surgery with CPB. INTERVENTIONS after CPB patients randomly received protamine according to our standard empirical ratio of 1 mg. protamine/100 U. heparin (group S, 24 patients), or to PDA result (group T, 26 patients) based on protamine titration method of determining circulating heparin. After protamine administration ACT and PDA were performed to assess heparin reversal and detect residual circulating heparin. Based on the PDA result, additional protamine was administered in both groups when required. MEASUREMENTS in both groups basal and post-heparin ACT values, protamine doses, ACT and PDA after protamine administration were measured. RESULTS The protamine dose was significantly lower (30%) in patients treated according to PDA. In 20% of patients showing normal ACT PDA revealed still circulating heparin, and additional protamine was required. In all other cases ACT and PDA both confirmed heparin reversal. CONCLUSIONS PDA allowed us to administer a significantly lower amount of protamine. This can reduce incidence of adverse effects of over- and under-infusion of protamine. PDA also proved to be more sensitive than ACT in detecting residual circulating heparin after protamine administration.

Abstract
OBJECTIVE Following the encouraging results obtained on CA 242 as an adjunctive marker for colorectal cancer this study was designed to compare the clinical behavior of CA 242 to that of its related marker CA 19-9. PATIENTS AND METHODS Sera from 630 patients with benign (n = 201) or malignant (n = 429) colorectal diseases were evaluated. Moreover, 50 patients with colorectal cancer were longitudinally monitored during. post-surgical follow-up for either a minimum of 5 years or until time of recurrence. Serum CEA, CA 19-9 and CA 242 levels were determined before treatment and at each scheduled follow-up. RESULTS The distribution of CA 242 levels in colorectal cancer patients demonstrated a similar positivity rate (32.9%) compared to that of CA 19-9 (29.8%), although both sensitivities were lower than that of CEA (43.8%). Moreover, elevated CA 242 serum levels were found in metastatic disease (58.2%). A longitudinal evaluation demonstrated that serum CEA, CA 19-9 and CA 242 levels were elevated in 63.9%, 63.9% and 66.7% of recurrences. Combined evaluation of CEA, CA 19-9 and CA 242 serum levels in the overall population demonstrated a complementarity of CEA with the latter two markers. Conversely, a highly significant correlation was observed, suggesting that the two assays might recognize the same macromolecular complex. CONCLUSION CA 242 determination does not seem to offer a particular advantage over CA 19-9, while CEA remains the marker of choice in monitoring colorectal cancer patients.

Abstract
The aims of this anthropometric study on 486 non-institutionalized subjects aged 60 and over were to assess the body mass index (BMI), to evaluate possible sex and age-linked differences of BMI and to find whether there were any correlations with systolic and diastolic blood pressure. To this end, the subjects were divided into three age groups: A: 60-69 years, B: 70-79 years and C: > or =80 years old. The results showed a high prevalence (74%) of overweight or clearly obese subjects (BMI >25.1 for men and BMI > 23.9 for women) (70% male and 77% female). Both the BMI and diastolic blood pressure showed a decreasing trend in the three age groups and were significantly correlated in the total population (p < 0.001). A dietary investigation using a 24-hour recall method, repeated on three separate days, was carried out on a subsample of 90 subjects, selected at random from the total population. They underwent in-depth anthropometric assessment (BMI, four skinfolds, mid-arm, waist and hip circumferences, midarm muscle and fat areas, body fat percent). The trend of the anthropometric assessment reflected that of the total population. Total energy intake in both sexes did not significantly differ from the Italian RDA (Recommended Dietary Allowance). As regards the three macronutrients, no significant differences in protein and carbohydrate intakes were found between the sexes. However, in the females, fat intake was over the Italian DRA (30%) and below it in the males. Calcium intake was lower than the Italian RDA (1,000 mg/day) in most males (77%) and females (89%). However, iron and vitamin intakes were adequate in most subjects. As regards age-linked differences, there were non significant changes in the percentage of energy intake from proteins of the males whereas this decreased with age and was significantly different (p < 0.05) in the females. No significant differences were found in the percentage of energy intake from carbohydrates and fats.

Abstract
AIMS Some low-grade malignant tumours arising in the abdomen tend to remain loco-regionally confined to peritoneal surfaces, without systemic dissemination. In these cases complete surgical tumour cytoreduction followed by intra- or post-operative regional chemotherapy has curative potential. The aim of this study was to evaluate the outcome for patients treated in this way. METHODS Peritonectomy was performed, involving the complete removal of all the visceral and parietal peritoneum involved by disease. After peritonectomy, hyperthermic antiblastic perfusion was carried out throughout the abdominopelvic cavity for 90 min, at a temperature of 41.5-42.5 degrees C, with mitomycin C (3.3 mg/m2/l) and cisplatin (25 mg/m2/l) (for appendicular or colorectal primaries), or cisplatin alone (for ovarian primaries). Alternatively, the immediate post-operative regional chemotherapy was performed with 5-fluorouracil (13.5 mg/kg) and Lederfolin (125 mg/m2) (for colonic or appendicular tumours) or cisplatin (25 mg/m2) (for ovarian tumours), each day for 5 days. RESULTS Thirty-five patients affected by extensive peritoneal carcinomatosis were submitted to peritonectomy, with no residual macroscopic disease in all cases except three. Twenty-six patients were able to undergo the combined treatment involving loco-regional chemotherapy. Complications were observed in 54% of the patients and led to death in four of them. At a mean follow-up of 17 months overall 2-year survival was 55.2%, with a median survival of 26 months. CONCLUSIONS After a learning curve of 18 months the feasibility of the integrated treatment increased to more than 90%, while mortality decreased dramatically. The curative potential of the combined therapeutic approach seems high in selected patients with peritoneal carcinomatosis not responding to systemic chemotherapy. Careful selection of patients can minimize the surgical risk, but the treatment should currently be reserved for clinical trials.

Abstract
BACKGROUND AND OBJECTIVES Low-grade malignant tumors arise in the abdomen, do not infiltrate, and "redistribute" on the peritoneum with no extraregional spreading. In these cases, aggressive surgery combined with localized chemotherapy may provide cure. METHODS After removing the tumor with the regional peritoneum en bloc, intraabdominal hyperthermic chemoperfusion was performed throughout the abdominopelvic cavity. Alternatively, early intraabdominal chemotherapy, starting on the first postoperative day, was administered for 5 days. RESULTS Forty patients affected with extensive peritoneal carcinomatosis underwent peritonectomy, with no residual macroscopic disease except in four cases. Seventy-five percent of the patients underwent locoregional chemotherapy. Major complications were observed in 40% of the patients and led to death in five; there was a direct correlation to the duration of surgery (P = 0.03). At a mean follow-up of 20 months, the overall 2-year survival was 61.4%, with a median survival of 30 months. CONCLUSIONS After a learning curve of 18 months, the feasibility of the integrated treatment increased to greater than 90%, and mortality dramatically decreased. The combined treatment resulted in a high survival rate in patients with extensive carcinomatosis who were no longer responsive to traditional therapies.
