Abstract
Copper is routinely supplemented to weanling pig diets at concentrations above nutritional requirements to enhance growth performance. We hypothesised that this effect depends on the source of Cu and its dietary concentration. We tested this in weaned pigs (26 d of age) over a 35-d period using a 2 × 3 factorial arrangement with two Cu-sources (CuSO4 and Cu2O, monovalent copper oxide, CoRouge®) and three supplementary dietary Cu-levels (15, 80 and 160 mg Cu/kg) as respective factors. Increasing Cu level linearly increased (P < 0.001) final BW and daily gain. These effects tended (P = 0.09) to be greater with Cu2O than CuSO4. Feed conversion ratio decreased linearly (P < 0.001) with increasing dietary Cu content, independent of Cu source. Plasma Cu, Zn and Fe levels were unaffected, whereas liver Cu content increased quadratically (P < 0.001) with increasing dietary Cu content, with a larger increase (P < 0.001) with CuSO4 than Cu2O. Bile Cu content increased quadratically (P = 0.025) with increasing Cu content, irrespective of Cu source. RT-qPCR analysis revealed that increasing Cu content quadratically (P = 0.009) increased duodenal but not ileal metallothionein 1A (MT1A) mRNA, with greater effect (P = 0.010) of CuSO4. Regardless of the Cu source, increasing Cu dose linearly increased (P = 0.006) duodenal DMT1/SLC11A2 mRNA but decreased ZIP4/SLC39A4 mRNA in duodenum (P < 0.001) and ileum (P < 0.005). ZnT10/SLC30A10 mRNA was significantly (P = 0.021) and numerically (P = 0.061) greater with Cu2O compared to CuSO4, in duodenum and ileum, respectively. Copper content quadratically modulated duodenal but not ileal transferrin receptor (P = 0.029) and ferric reductase CYBRD1 mRNA (P = 0.022). In hypothalamus, high Cu dose (P = 0.024) and Cu2O as source (P = 0.028) reduced corticotropin-releasing hormone (CRH) mRNA. Low versus high CuSO4 increased corticotropin-releasing hormone receptor (CRHR2) mRNA, while low Cu2O had the opposite effect (P = 0.009). In conclusion, incremental Cu intake enhanced growth performance, with a tendency for a greater effect of Cu2O. The lower increase in duodenal MT1A mRNA and liver Cu content indicates that less Cu from Cu2O was absorbed by gut and sequestered in liver. Thus, high Cu absorption is not essential for its growth-promoting effect and dietary Cu may affect intestinal Fe and Zn absorption via the active, transcellular route. The effects on hypothalamic CRH and CRHR2 expression indicate a role for the hypothalamus in mediating the effects of Cu on growth performance.

Abstract
The Italian patient association for Multiple Osteochondromas, Ollier Disease, and Maffucci Syndrome, Associazione Conto Alla Rovescia-ACAR Aps, conducted a mixed-methods study at its 2023 annual conference. The study included the Open Dialogue Approach and a feedback survey to identify the main priorities in the transitioning process from paediatric to adult healthcare for patients with Multiple Osteochondromas, Ollier Disease, and Maffucci Syndrome. The common needs identified by patients, families, caregivers, and healthcare professionals were coordination and continuity of care, patient empowerment and communication, social and practical support, and transition planning and support. This experience fostered a sense of collaboration and cooperation among stakeholders, helping to build trust and create a shared vision for improving the quality of care for these patients. Furthermore, it could be considered a starting point for other patient associations interested in using different approaches to identify the needs of their members and actively involve all stakeholders.

Abstract
Background Knot security of half-knot (H) sequences varies with rotation, but half-knots risk destabilisation. Objectives To investigate the rotation of half-hitch (S) sequences on knot security. Materials and Methods The loop and knot security of symmetrical and asymmetrical sliding and blocking half-hitch sequences was measured using a tensiometer. Results Loop security of symmetrical sliding half-hitch sequences is much higher than asymmetrical sequences, increasing from 6+2 to 21+2 and from 27+6 to 48+5 Newton (N) for 2 and 4 half-hitches respectively (both P<0.0001). Symmetrical sliding sequences are more compact and remain in the same plane, squeezing the passive thread, while asymmetrical sequences rotate loosely around the passive end. Blocking sequences are superior when asymmetrical since changing the passive end acts like changing rotation, transforming the asymmetrical sliding into a symmetrical blocking half-hitch on the new passive thread. The knot security of 2 sliding and 1 blocking half-hitch doubles from 52+3 to 98+2 N for the worst (asymmetric sliding and symmetric blocking, SSaSsb) or best rotation sequences (SSsSab). Adding a second asymmetric blocking half-hitch (Sab) increases security further to 105+3 N. The overall knot security of four-throw, correctly rotated, half-hitch (SSsSabSab) or half-knot (H2H1sH1s, H2H2a and H2H2s) sequences is similar for four suture diameters. Conclusion Rotation affects the security of half-hitch sequences, which should be symmetrical when sliding, and asymmetrical when blocking. What is new? Half-hitch sequences are clinically superior to half-knot sequences. They do not risk destabilisation, and loop security improves approximation of tissues under traction, permitting tight knots.

Abstract
PURPOSE/OBJECTIVE(S) Malignant Pleural Mesothelioma (MPM) is a rare but aggressive intrathoracic malignancy with an overall poor prognosis. Neoadjuvant chemotherapy, surgery and then radiotherapy is the standard of care in early-stage disease. Our study aim is to evaluate the feasibility and toxicity of the novel adjuvant RT in accelerated hypofractionation. We report the lung toxicity preliminary results of the first patients entreated. MATERIALS/METHODS Starting in 2017, 29 MPM patients were enrolled in the trial (IRST trial 163). All patients were treated with accelerated hypofractionated radiotherapy using a helical 3-D CRT and IMRT system and intensity-modulated arc therapy. We conducted a prospective mono-institutional clinical trial enrolling cyto-histological proven, MPM patients. The major exclusion criteria were: previous thorax radiotherapy, contralateral mediastinum involvement (N3) and/or M1, interstitial pneumopathy, active pneumonitis, and fissural disease. The prescription dose was 30 Gy in five daily fractions, while an inhomogeneous dose escalation to 40 Gy was prescribed based solely upon the presence of gross residual tumor. All patients were treated in a 3-D CRT and IMRT system. Patients underwent functional lung study before to start radiotherapy treatment, 2 months and 6 months after the end of the treatment. The organs at risk dose-volume histograms were converted to a 2-Gy equivalent dose, and we closely adhered to the dose constraints of the literature data. We in particular analyzed lung toxicity of the first 20 patients. RESULTS No G3/G4 lung toxicity was found. We reported 65.0% G1 pneumonitis and 10% G2 as acute lung toxicity. The majority of the G1 patients had only mild symptoms and pneumonitis was described only for radiologic features with no need for medical therapy. Other respiratory toxicities were G1-G2 cough in 50% of the patients; G1 dyspnea occurred in 65% of the patients and G2 in the 15%. The total lung mean dose was 18 Gy (range 13 Gy-23 Gy), and the contralateral lung mean dose was 2 Gy (range 1 Gy-2 Gy). The median value of Forced Expired Volume in one second (FEV1) recorded was 75.5% (range: 46%-137%) before the treatment was started, the median value of Forced Vital Capacity (FVC) at baseline was 74 (range 46-123) with progressive decreasing values through time. DLCO has also been reported with a progressive decrease over time after radiotherapy treatment. No case of respiratory failure was reported after treatment. CONCLUSION Treatment of the intact lung with pleural intensity-modulated arc irradiation is a novel treatment strategy that appears to be safe, feasible, and without a high grade of lung toxicity. More investigations are mandatory. The protocol is ongoing.

Abstract
PURPOSE/OBJECTIVE(S) Hypoxia is thought to play a role in tumor development, angiogenesis and growth, and resistance to chemotherapy, antiangiogenic therapy and radiotherapy (RT) in a large number of human cancers. Brain tumors, especially highly aggressive GBM with its necrotic tissue, are more likely to be affected by hypoxia. The median partial pressure of oxygen (PO2) of high-grade gliomas in patients under anesthesia was approximately 5-7 mmHg, with a significant proportion of PO2 values <2.5 mmHg. The radiosensitivity of brain tumors could potentially be increased by performing hyperbaric oxygenation (HBO) before the RT session. We propose an innovative approach to improve the efficacy of accelerated hypofractionated Stereotactic Radiotherapy (HSRT) after HBO (HBO-RT) for the treatment of recurrent HGG (rHGG). The primary objective of this study is to evaluate the disease control rate (DCR) at 3 months. The secondary Objectives are: - Safety assessment (acute and late toxicity). - Overall Survival (OS), - Progression Free Survival (PFS). MATERIALS/METHODS We enrolled 14 patients (aged >18 years) with rHGG detected using MRI. A total dose of 15-25 Gy was administered in daily 5-Gy fractions for 3-5 consecutive days after daily HBO. RESULTS Median follow-up from re-irradiation was 22.8 months (range: 2.0-24.2 months). The disease control rate 3-months after HBO-RT was 50% (23.0-76.9). Six- and 12-month Progression-free survival was 35.7% (95% CI: 13-59.4) and 10.7% (95% CI: 0.8-35.4), respectively. Median overall survival of HBO-RT was 10.7 months (95% CI: 6.6-24.2). No acute or late neurologic toxicity >grade (G)2 was observed. CONCLUSION HSRT combined to HBO seems effective and safe in the treatment of rHGG.

Abstract
Encapsulation is a valuable strategy to protect and deliver anthocyanins (ACNs), phenolic compounds with outstanding antioxidant capacity but limited stability. In this study, coacervation was used to encapsulate an ACN-rich red cabbage extract (RCE). Two agri-food by-product polymers, whey protein isolate (WPI) and apple high-methoxyl pectin (HMP), were blended at pH 4.0 in a specific ratio to induce the formation of nanoparticles (NPs). The process optimisation yielded a monodispersed population (PDI < 0.200) of negatively charged (-17 mV) NPs with an average diameter of 380 nm. RCE concentration influenced size, charge, and antioxidant capacity in a dose-dependent manner. NPs were also sensitive to pH increases from 4 to 7, showing a progressive breakdown. The encapsulation efficiency was 30%, with the retention of ACNs within the polymeric matrix being influenced by their chemical structure: diacylated and/or C3-triglucoside forms were more efficiently encapsulated than monoacylated C3-diglucosides. In conclusion, we report a promising, simple, and sustainable method to produce monodispersed NPs for ACN encapsulation and delivery. Evidence of differential binding of ACNs to NPs, dependent on specific acylation/glycosylation patterns, indicates that care must be taken in the choice of the appropriate NP formulation for the encapsulation of phenolic compounds.

Abstract
We report the first example of very efficient NIR Circularly Polarized Luminescence (CPL) (around 970 nm) in water, obtained thanks to the combined use of a chiral Yb complex and of poly lactic‐co‐glycolic acid (PLGA) nanoparticles. [YbL(tta)2]CH3COO (L=N, N’‐bis(2‐pyridylmethylidene)‐1,2‐(R,R+S,S) cyclohexanediamine and tta=2‐thenoyltrifluoroacetonate) shows good CPL in organic solvents, because the tta ligands efficiently sensitize Yb NIR luminescence and the readily prepared chiral ligand L endows the complex with the necessary dissymmetry. PLGA nanoparticles incorporate the complex and protect the metal ion from the intrusion of solvent molecules, while ensuring biocompatibility, water solubility and stability to the complex. Hydrophilic NIR‐CPL optical probes can find applications in the field of NIR‐CPL bio‐assays.

Abstract
The objective of this paper is to explore the postural effect of galvanic vestibular stimulation (GVS) in camptocormia. It is a retrospective case series of 7 Parkinson disease and camptocormia patients. Binaural monopolar GVS was administered. Main outcome variable was trunk forward flexion (TFF), assessed pre and immediately post GVS, and one month after. The TFF was assessed in the standing position, with open and closed eyes. The Berg balance scale was assessed before and 1 month after GVS. The TFF immediately after the GVS showed a reduction of 2.3 cm (p = 0.091) in the first reading, and after a 1-min stance (p = 0.025). Four of 5 patients maintained or even improved this effect a month after (p = 0.082). No changes in Berg balance scale were observed. Our results suggest an acute improvement in posture after one session of GVS, which significantly decreased TFF. Most of the results had a marginal significance due to small sample size.

Abstract
1. The bioavailability of a trace mineral source is related to its intestinal solubility (bioaccessibility), which in turn is determined by its physicochemical properties. It is still not clear which characteristics are more relevant in affecting solubility and bioavailability of mineral sources. Zinc oxide (ZnO) is a common feed additive used to supplement zinc in the diet of monogastric animals. However, different sources have shown variable responses on animal bioavailability.2. This study hypothesised that different sources of feed grade ZnO have various physicochemical features that lead to distinct bioavailability values. Feed grade ZnO samples collected from the feed industry worldwide were characterised for their physicochemical features and tested in broilers to allow bioavailability determined.3. A total of 135 male Cobb broiler chickens were fed a standard starter diet from day 1 after hatching up to d 7. At d 8, animals were allocated in individual cages and fed one of the following dietary treatments during 15 days: a basal diet with 23.5 ppm of zinc and seven test diets with supplemented ZnO or zinc sulphate (ZnSO4) at 6 or 12 ppm.4. Different sources of ZnO showed an effect of solubility in the stomach and supplementation influenced total Zn levels in the ileum. The bioavailability of the different sources varied from 49% to 160% in relation to ZnSO4. Aggregate size of particles seems to explain most of the variability in the bioavailability of the different sources tested in broilers. In conclusion, physicochemical properties of ZnO can partly explain the variability observed in terms of biological value.

Abstract
Magnetococcus marinus magnetosome-associated protein MamC, expressed as recombinant, has been proven to mediate the formation of novel biomimetic magnetic nanoparticles (BMNPs) that are successful drug nanocarriers for targeted chemotherapy and hyperthermia agents. These BMNPs present several advantages over inorganic magnetic nanoparticles, such as larger sizes that allow the former to have larger magnetic moment per particle, and an isoelectric point at acidic pH values, which allows both the stable functionalization of BMNPs at physiological pH value and the molecule release at acidic (tumor) environments, simply based on electrostatic interactions. However, difficulties for BMNPs cell internalization still hold back the efficiency of these nanoparticles as drug nanocarriers and hyperthermia agents. In the present study we explore the enhanced BMNPs internalization following upon their encapsulation by poly (lactic-co-glycolic) acid (PLGA), a Food and Drug Administration (FDA) approved molecule. Internalization is further optimized by the functionalization of the nanoformulation with the cell-penetrating TAT peptide (TATp). Our results evidence that cells treated with the nanoformulation [TAT-PLGA(BMNPs)] show up to 80% more iron internalized (after 72 h) compared to that of cells treated with BMNPs (40%), without any significant decrease in cell viability. This nanoformulation showing optimal internalization is further characterized. In particular, the present manuscript demonstrates that neither its magnetic properties nor its performance as a hyperthermia agent are significantly altered due to the encapsulation. In vitro experiments demonstrate that, following upon the application of an alternating magnetic field on U87MG cells treated with BMNPs and TAT-PLGA(BMNPs), the cytotoxic effect of BMNPs was not affected by the TAT-PLGA enveloping. Based on that, difficulties shown in previous studies related to poor cell uptake of BMNPs can be overcome by the novel nanoassembly described here.

Abstract
OBJECTIVE The objective of this work is to compare cellular toxicity in vitro of two resins for orthodontic use: an auto-polymerizable composite and a photo-polymerizable composite. MATERIALS AND METHODS Samples were obtained by joining a couple of steel orthodontic brackets by using auto-polymerizing or photo-polymerizing resin. We used a halogen lamp, a mini LED lamp and a fast LED lamp used for orthodontics cure for 40 seconds. The 3T3 Swiss cellular line of fibroblasts was used. The samples obtained were used to determine the cellular toxicity in vitro using the Neutral Red Up-take (NRU) and the 3-(4,5-dimethylthiazol-2-Yl)-2,5-diphenyltetrazolium bromide (MTT) assay. RESULTS Toxicity of the extract appraised at a low level at MTT and NRU assays. There were statistically relevant differences between the toxicity induced by the auto-polymerizing material and the toxicity induced by the photo-polymerizing composite material, polymerized with the blue-light lamp (p < 0.001) and with the mini LED lamp (p < 0.05). CONCLUSIONS From the data collected in this study, we can conclude that both resins show a low level of cytotoxicity that, in the case of photochemical polymerizing resin, depends on the characteristics of the lamp.

Abstract
The aim of this study was to evaluate the periodontal healing of the distal sites of the mandibular second molars, comparing the extraction therapy of the third molar with and without PRF adjunct into the postextraction alveolus. The study sample was composed by 40 consecutive patients who underwent extraction of mandibular third molars. Patients were divided in two groups: the last 20 participants who have only been subjected to extraction (spontaneous healing group, SHG) and the first 20 patients who had PRF adjunct (PRF group, PG). Healing was evaluated by analyzing the variations in terms of PPD (Probing Pocket Depth), REC (Recession), CAL (Level of Clinical Attachment), BoP (Bleeding on Probing) and GI (Gingival Index) from Baseline to further follow-ups at 1 month and 3 months. The disto-vestibular (DV) and disto-lingual (DL) PPD values of the second mandibular molar were measured at Baseline and after three months in the two groups. Patients of the PG group showed lower PPD values at 1 month and 3 months postoperatively: DV: 3.6±1.09 - DL: 3.5±1.15 and DV: 2.5±0.83 - DL: 2.6±1.09, respectively. Patients belonging to the SHG also showed lower PPD values, reporting respectively the following DV values after 3 months: 2.7±0.86 - DL: 2.75±0. 85. However, there was no statistically significant difference comparing the results obtained in PG and SHG groups at 1 and 3 months (p>0.05). The insertion of PRF inside the post-extraction alveolus of the mandibular third molar leads to limited improvement in terms of periodontal healing, compared to extraction therapy only.

Abstract
Exposure to low ozone concentrations is used in medicine as an adjuvant/complementary treatment for a variety of diseases. The therapeutic potential of low ozone concentrations relies on their capability to increase the nuclear translocation of the Nuclear factor erythroid 2-related factor 2 (Nrf2), thus inducing the transcription of Antioxidant Response Elements (ARE)-driven genes and, through a cascade of events, a general cytoprotective response. However, based on the controversial role of Nrf2 in cancer initiation, progression and resistance to therapies, possible negative effects of ozone therapy may be hypothesised in oncological patients. With the aim to elucidate the possible changes in morphology, migration capability and proliferation of cancer cells following mild ozone exposure, we performed wound healing experiments in vitro on HeLa cells treated with low ozone concentrations currently used in the clinical practice. By combining a multimodal microscopy approach (light and fluorescence microscopy, scanning electron microscopy, atomic force microscopy) with morphometric analyses, we demonstrated that, under our experimental conditions, exposure to low ozone concentrations does not alter cytomorphology, motility and proliferation features, thus supporting the notion that ozone therapy should not positively affect tumour cell growth and metastasis.

Abstract
Photosystem I (PSI) is a pigment binding multisubunit protein complex involved in the light phase of photosynthesis, catalyzing a light-dependent electron transfer reaction from plastocyanin to ferredoxin. PSI is characterized by a photochemical efficiency close to one, suggesting its possible application in light-dependent redox reaction in an extracellular context. The stability of PSI complexes isolated from plant cells is however limited if not embedded in a protective environment. Here we show an innovative solution for exploiting the photochemical properties of PSI, by encapsulation of isolated PSI complexes in PLGA (poly lactic-co-glycolic acid) organic microparticles. These encapsulated PSI complexes were able to catalyze light-dependent redox reactions with electron acceptors and donors outside the PLGA microparticles. Moreover, PSI complexes encapsulated in PLGA microparticles were characterized by a higher photochemical activity and stability compared with PSI complexes in detergent solution, suggesting their possible application for ex vivo photocatalysis.

Abstract
OBJECTIVE To define the electroclinical phenotype and long-term outcomes in a cohort of patients with inv dup (15) syndrome. MATERIAL AND METHODS The electroclinical data of 45 patients (25 males) affected by inv dup (15) and seizures were retrospectively analysed, and long-term follow-up of epilepsy was evaluated. RESULTS Epilepsy onset was marked by generalized seizures in 53% of patients, epileptic spasms in 51%, focal seizures in 26%, atypical absences in 11% and epileptic falls in 9%. The epileptic syndromes defined were: generalized epilepsy (26.7%), focal epilepsy (22.3%), epileptic encephalopathy with epileptic spasms as the only seizure type (17.7%) and Lennox-Gastaut syndrome (33.3%). Drug-resistant epilepsy was detected in 55.5% of patients. There was a significant higher prevalence of seizure-free patients in those with seizure onset after the age of 5 years and with focal epilepsy, with respect to those with earlier epilepsy onset because most of these later developed an epileptic encephalopathy (69.2% vs 34.4%; P = .03), usually Lennox-Gastaut Syndrome in type. In fact, among patients with early-onset epilepsy, those presenting with epileptic spasms as the only seizure type associated with classical hypsarrhythmia achieved seizure freedom (P < .001) compared to patients with spasms and other seizure types associated with modified hypsarrhythmia. CONCLUSIONS Epilepsy in inv dup (15) leads to a more severe burden of disease. Frequently, these patients show drug resistance, in particular when epilepsy onset is before the age of five and features epileptic encephalopathy.

Abstract
INTRODUCTION AND OBJECTIVE To evaluate complications, morbidity and oncologic outcomes of pelvic exenteration as treatment for gynecologic malignancies. MATERIALS AND METHODS Between 2008 and 2015, a total of 35 patients underwent pelvic exenteration, due to recurrence of gynecological cancer. Surgical outcomes, early and late postoperative complications, and recurrence/survival outcomes were assessed. RESULTS Mean patient age was 53.8 years. Anterior exenteration was done in 20 patients, while 15 were total exenterations. Ileal conduit was done in 24 patients, while 8 received a neobladder and 3 a cutaneous ureterostomy. Postoperative complications were divided in 2groups, early (<30 days) and late complications (>30 days). A total of 25 patients (71.4%) had one or more early complications; 16 (45.7%) had fever due to a urinary tract infection, pyelonephritis or intra-abdominal collection; 2 (5.7%) developed a vesicovaginal fistula; 4 (11.4%) a rectovaginal fistula; 3 (8.5%) acute kidney failure and one (2.85%) uronephrosis. Regarding to late complications, 8patients (22.8%) had fever. Six (17%) presented with uronephrosis, and 5 (14.2%) with ureteral-pouch stricture. Five patients (14.2%) had acute renal insufficiency, 3 (8,6%) rectovaginal fistula and one (2.85%) urinary fistula. Mean follow up time was 20.3 month (2-60). A total of 22patients (62.8%) were free of disease. Another 13 (37.1%) patients relapsed. Only 4 (11.4%) patients died after pelvic exenteration due to underlying disease. CONCLUSION Pelvic exenteration has a high rate of complications and morbidity, but can be the last curative opportunity in patients with recurrent or persistent gynecologic malignancies. This procedure should be performed by multidisciplinary, experienced teams in a tertiary medical center.

Abstract
Kinetics of the growth of TPPS4 porphyrin J-aggregates slow down in the order H2SO4 > HCl > HBr > HNO3 > HClO4, in agreement with the Hofmeister series. The rate constants and the extent of chirality correlate with the structure-making or breaking abilities of the different anions with respect to the hydrogen bonding network of the solvent.

Abstract
OBJECTIVE A previous European cost-utility study reported that use of buccal midazolam in the community setting for the treatment of prolonged seizures (ie, seizures lasting ≥5 minutes) in children was associated with an overall €12 507 399 reduction in annual costs charged to the Italian national health service compared with rectal diazepam. We re-evaluated these findings by applying a more conservative approach. METHODS The Italian Delphi panel reconvened to apply a more conservative assessment of available reports. A decision-tree model was used, allowing for different treatment pathways depending on whether or not a caregiver administers treatment, an ambulance is required for transport of the child to hospital, and an inpatient stay is required. Direct medical costs were derived from Italian healthcare system data. Estimates of the annual number of prolonged tonic-clonic seizures expected in the country were based on studies which assessed seizure duration using video-EEG recordings and medical records. RESULTS Although drug acquisition costs were greater for buccal midazolam than for rectal diazepam, the acquisition cost difference was outweighed by larger cost savings resulting mostly from a reduction in hospital admissions. Assuming that 1.2% of tonic and/or clonic seizures occurring in children and adolescents over a 12-month period are prolonged, the annual nationwide reduction in costs from preferring buccal midazolam to rectal diazepam was estimated at €3 577 587.9. CONCLUSIONS In this more conservative revised analysis, the high cost of buccal midazolam is still counteracted by greater cost savings compared with rectal diazepam, but cost reduction was less than previously estimated.

Abstract
PURPOSE The role played by radiation therapy after pleurectomy/decortication or surgical biopsy in malignant pleural mesothelioma is uncertain. We treated patients with accelerated hypofractionated radiotherapy using helical tomotherapy and intensity-modulated arc therapy in an attempt to keep lung toxicity to a minimum. The present study reports the feasibility and toxicity of this approach. MATERIAL AND METHODS Between 2008 and 2012, 36 patients with malignant pleural mesothelioma underwent accelerated hypofractionated radiotherapy to the hemithorax after pleurectomy/decortication (19 patients) or biopsy (17 patients). The prescription dose was 25Gy in five fractions over 5 consecutive days. RESULTS We observed three patients with G3 pneumonitis, five cases of grade 2 dyspnea and six cases of grade 2 cough. The median follow-up was 37 months (range: 3-54 months). The median overall survival for patients who underwent pleurectomy/decortication followed by radiotherapy was 21.6 months [95% confidence interval (95% CI): 15.5-24.1] compared to 19.4 months for patients not submitted to surgery. CONCLUSION Treatment of intact lung with pleural intensity-modulated arc irradiation in malignant pleural mesothelioma patients with malignant pleural mesothelioma proved safe and feasible, with an acceptable rate of pneumonitis. Survival rates were encouraging for both biopsy-only and pleurectomy/decortication groups. We are currently conducting a phase II dose escalation trial in a similar patient setting to prospectively evaluate the impact of radiotherapy on toxicity, disease-free survival and overall survival.

Abstract
Dilute aqueous solutions of anionic meso-4-sulfonatophenyl-porphyrin (TPPS) extract zinc(ii) ions from glass or quartz surfaces at room temperature and efficiently form the corresponding metal complex (ZnTPPS). The partial or complete formation of ZnTPPS has been probed by UV/Vis spectroscopy and both static and time-resolved fluorescence. The source of zinc(ii) ions has been clearly identified through inductively coupled plasma optical emission spectrometry. The presence of increasing amounts of ZnTPPS slows down the rate of TPPS J-aggregate formation in acid solution. This influences the nucleation step and has a profound impact on the onset of chirality in these species. This evidence indicates the important role of this adventitious metal ion in the interpretation of various spectroscopic and kinetic data for the self-assembly of the TPPS porphyrin and provides some insights into controversial findings on their chirality. The use of this metal derivative as the starting compound for in situ formation of monomeric TPPS is suggested.

Abstract
A hybrid bio-organic electrochemical transistor was developed by interfacing an organic semiconductor, poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonate), with the Physarum polycephalum cell. The system shows unprecedented performances since it could be operated both as a transistor, in a three-terminal configuration, and as a memristive device in a two terminal configuration mode. This is quite a remarkable achievement since, in the transistor mode, it can be used as a very sensitive bio-sensor directly monitoring biochemical processes occurring in the cell, while, as a memristive device, it represents one of the very first examples of a bio-hybrid system demonstrating such a property. Our system combines memory and sensing in the same system, possibly interfacing unconventional computing. The system was studied by a full electrical characterization using a series of different gate electrodes, namely made of Ag, Au and Pt, which typically show different operation modes in organic electrochemical transistors. Our experiment demonstrates that a remarkable sensing capability could potentially be implemented. We envisage that this system could be classified as a Bio-Organic Sensing/Memristive Device (BOSMD), where the dual functionality allows merging of the sensing and memory properties, paving the way to new and unexplored opportunities in bioelectronics.
