Abstract
A suppressive antiretroviral therapy (ART) is necessary to prevent mother-to-child transmission (MTCT) of HIV during pregnancy. During this period, it is recommended to continue an ongoing safe and suppressive regimen, but history of multiclass drug-resistance (MDR) might need tailored, uncommon approaches posing tolerability and toxicity issues. This is the case of a 33 years of age, vertically infected woman with MDR HIV infection suppressed on a darunavir/cobicistat + atazanavir regimen switched during pregnancy to lamivudine + darunavir/ritonavir + dolutegravir 50 mg bis-in-die, maintaining complete viral suppression and delivering via caesarian section and without zidovudine (AZT) intrapartum prophylaxis a healthy HIV-negative newborn who received AZT post-exposure prophylaxis and showed regular growth patterns up to 2 years. Our case shows how archived MDR might complicate the preservation of HIV RNA suppression and highlights the importance of a tailored, multidisciplinary approach for pregnant women with MDR HIV and their newborns.

Abstract
PURPOSE To investigate the impact on future reproductive potential of systemic methotrexate (MTX) administration, uterine artery embolization (UAE) and expectant management as treatments of caesarean scar pregnancy (CSP) and to assess their efficacy and safety. BASIC PROCEDURES We retrospectively analysed patients with a diagnosis of CSP treated in a five years' period (2014-2018). Hospitalization, hCG normalization, menstrual cycle recovery, ultrasound restitutio ad integrum times, reproductive desire accomplishment after the resolution of the picture, and outcomes of subsequent pregnancies were considered. Only patients for whom complete diagnosis, treatment and follow-up data were available could be considered for study entry. MAIN FINDINGS A total of 21 patients were included. Three of them were managed expectantly. In two cases spontaneous abortion occurred and one case underwent caesarean delivery at 35 weeks of gestation for complete placenta previa with hysterectomy for post partum haemorrhage. Seven patients were treated with systemic MTX. Median [IQR] times of hospitalization, hCG normalization, menstrual cycle recovery and ultrasound restitutio ad integrum were 21 days [10-26 days], 52 days [18-64 days], 8 weeks [6-10 weeks] and 8 weeks [6-11 weeks] respectively. At the end of follow up, 80% (95%CI [38-96%]) of patients with reproductive desire achieved at least one live birth. Eleven patients were treated with UAE combined with MTX. Median [IQR] times of hospitalization, hCG normalization, menstrual cycle recovery and ultrasound restitutio ad integrum were 14 days [12-20 days], 43 days [30-52 days], 8 weeks [4-12 weeks] and 8 weeks [8-10 weeks], respectively. Of those who expressed a reproductive desire after treatment, 80% (95%CI [49-94%]) achieved at least one live birth. In all included patients, the menstrual cycle was restored. PRINCIPAL CONCLUSIONS Reproductive potential of women treated for CSP was preserved after both systemic MTX administration and systemic MTX combined with UAE. Both strategies proved to be safe.

Abstract
It is unknown whether moderate thrombocytopenia represents a risk factor for post‐partum haemorrhage (PPH). We assessed PPH risk among women with a platelet count of between 100 and 50 × 109/l and stratified the risk for O/non‐O blood group. We included consecutive women undergoing vaginal delivery or caesarean section with moderate thrombocytopenia. Women with >150 × 109/l platelets at delivery were selected as controls and matched for age, type of birth and ethnicity. Odds ratios (ORs) with their 95% confidence intervals (95% CIs) were calculated as risk estimates. A total of 94 thrombocytopenic women and 94 controls were included in the study. The rate of PPH was significantly higher in thrombocytopenic women than in controls (37% vs. 10%, p < 0.001); there was a higher risk of PPH in the thrombocytopenic group when compared to the control group (adjusted OR 4.7, 95% CI 2.1–10.8, p < 0.01) and this association was stronger in blood group O carriers (adjusted OR 11.0, 95% CI 2.4–49.6, p < 0.01). In conclusion, our study shows that a moderate thrombocytopenia is a risk factor for PPH, especially in blood group O carriers.

Abstract
The pathologist is often called to define the origin of tumors through the help of ancillary studies, mainly immunohistochemical stainings. In this setting, the differential diagnosis between intestinal adenocarcinomas, other tumors with intestinal-type morphology, and adenocarcinomas metastatic to the bowel can be particularly difficult. In such cases, an accurate assessment of the disease is required to address the patients to the optimal treatment. Immunohistochemistry offers the use of multiple antibodies: the integrated evaluation of specific stainings can lead to a correct diagnosis. Particularly, the use of cytokeratins, mucins, and β-catenin could be of great help in most cases. In addition, recently, novel specific markers such as SATB2 and AMACR have been introduced, improving the utility of immunohistochemistry in the differential diagnosis of intestinal-type and intestinal adenocarcinomas.

Abstract
BACKGROUND Incisional hernia is a frequent postoperative complication after midline laparotomy. Prophylactic mesh augmentation in abdominal wall closure after elective surgery is recommended, but its role in emergency surgery is less well defined. METHODS This prospective randomized trial evaluated the incidence of incisional hernia in patients undergoing urgent midline laparotomy for clean-contaminated surgery. Closure using a slowly absorbable running suture was compared with closure using an additional sublay mesh (Parietex ProGrip™). Patients were randomized just before abdominal wall closure using computer-generated permuted blocks. Patients, care providers, staff collecting data, and those assessing the endpoints were all blinded to the group allocation. Patients were followed up for 24 months by means of clinical and ultrasonographic evaluations. RESULTS From January 2015 to June 2018, 200 patients were randomized: 100 to primary closure (control group) and 100 to Parietex ProGrip™ mesh-supported closure (mesh group). Eight patients in the control group and six in the mesh group were lost to follow-up. By 24 months after surgery, 21 patients in the control group and six in the mesh group had developed incisional hernia (P = 0.002). There was no difference between groups in the incidence of haematoma (2 versus 5; P = 0.248) and superficial wound infection (4 versus 5; P = 0.733). Multivariable analysis confirmed the role of mesh in preventing incisional hernia (odds ratio 0.11, 95 per cent c.i. 0.03 to 0.37; P < 0.001). One patient in the mesh group required mesh removal because of deep infection. CONCLUSION Prophylactic mesh-augmented abdominal wall closure after urgent laparotomy in clean-contaminated wounds is safe and effective in reducing the incidence of incisional hernia. Registration number: NCT04436887 (http://www.clinicaltrials.gov). GRAPHICAL ABSTRACT An RCT was conducted to compare the widely recommended midline laparotomy closure using a slowly absorbable running suture with closure using a sublay mesh (Parietex ProGrip™), in patients undergoing urgent midline laparotomy for clean-contaminated surgery. Patients were followed up for 24 months with clinical and ultrasonographic evaluation during outpatient visits. Prophylactic reinforcement of the midline abdominal wall, using a ProGrip™ Parietex mesh in the retromuscular position, at the time of urgent laparotomy in clean-contaminated wounds was safe and effective in reducing the incidence of incisional hernia, although larger studies with longer follow-up are required.

Abstract
OBJECTIVE Anaplastic lymphoma kinase (ALK) gene has been demonstrated to be rearranged, mutated or amplified in several haematological and solid tumors. Moreover, the use of ALK inhibitors has recently revolutionized the treatment of ALK-rearranged patients affected by non-small cell lung carcinoma. Herein we review the genetic alterations of ALK in melanocytic neoplasms described in literature, focusing on their potential diagnostic and predictive role. MATERIALS AND METHODS The Authors reviewed the pertinent literature through research on PubMed server was performed typing the terms "ALK", "Anaplastic lymphoma kinase", "ALKATI", "Melanoma", "Spitz", "Spitzoid". RESULTS ALK translocations were demonstrated in melanocytic neoplasms, particularly in acral melanoma and spitzoid tumors. ALKATI was described in primary and metastatic melanoma, indicating its early occurrence in oncogenesis, with varying immunohistochemical expression of the protein. CONCLUSIONS The identification of the specific type of ALK mutations could be interesting for planning biologic therapy of melanoma patients. Further studies are needed to evaluate the possibility to introduce an ALK-targeted therapy in patients affected by malignant melanoma.

Abstract
OBJECTIVE In human pathology, SARS-CoV-2 utilizes multiple molecular pathways to determine structural and biochemical changes within the different organs and cell types. The clinical picture of patients with COVID-19 is characterized by a very large spectrum. The reason for this variability has not been clarified yet, causing the inability to make a prognosis on the evolution of the disease. MATERIALS AND METHODS PubMed search was performed focusing on the role of ACE 2 receptors in allowing the viral entry into cells, the role of ACE 2 downregulation in triggering the tissue pathology or in accelerating previous disease states, the role of increased levels of Angiotensin II in determining endothelial dysfunction and the enhanced vascular permeability, the role of the dysregulation of the renin angiotensin system in COVID-19 and the role of cytokine storm. RESULTS The pathological changes induced by SARS-CoV-2 infection in the different organs, the correlations between the single cell types targeted by the virus in the different human organs and the clinical consequences, COVID-19 chronic pathologies in liver fibrosis, cardiac fibrosis and atrial arrhythmias, glomerulosclerosis and pulmonary fibrosis, due to the systemic fibroblast activation induced by angiotensin II are discussed. CONCLUSIONS The main pathways involved showed different pathological changes in multiple tissues and the different clinical presentations. Even if ACE2 is the main receptor of SARS-CoV-2 and the main entry point into cells for the virus, ACE2 expression does not always explain the observed marked inter-individual variability in clinical presentation and outcome, evidencing the complexity of this disorder. The proper interpretation of the growing data available might allow to better classifying COVID-19 in human pathology.

Abstract
BACKGROUND Recent evidence supports elective induction of labor at 39 weeks in low-risk pregnancies to improve maternal and perinatal outcomes. This evidence includes the ARRIVE trial (A Randomized Trial of Induction Versus Expectant Management). However, concerns have been raised on the external validity of the ARRIVE trial, especially with regard to the demographic and clinical characteristics of the pregnant women recruited. OBJECTIVE This study compared the outcomes in a cohort of consecutive pregnant women, who fulfilled the criteria of the ARRIVE trial and were managed expectantly in an Italian referral academic hospital, with those reported in the expectant and induction arms of the ARRIVE trial. STUDY DESIGN This was a retrospective single-center study. Consecutive low-risk nulliparous women who fulfilled the ARRIVE trial criteria were evaluated for eligibility at 36-38 weeks of gestation. Those who neither developed complications nor delivered spontaneously before 39 weeks were eligible for this comparative analysis. Maternal and fetal growth and wellbeing were screened and monitored from 36 to 38 weeks of gestation. RESULTS A total of 1696 patients met the established criteria at recruitment. Of these, 343 spontaneously delivered in <39 weeks, 82 delivered because of maternal indication, and 37 for fetal indication. A total of 1234 pregnant women were eligible for comparison with the elective induction and the expectant management groups of the ARRIVE trial. The socioeconomic status was significantly better, maternal age was significantly higher, and body mass index was significantly lower in our cohort. Cesarean section rate in our cohort was lower than that of the expectant group of the ARRIVE trial (18.7 vs. 22.2%; p = 0.02) and similar to that of the elective induction group (18.7 vs. 18.6%). A new diagnosis of hypertensive disorders during expectant management was noted in 1.6% in our cohort vs. 14.1% in the ARRIVE arm. Among the different obstetric outcomes, only the prevalence of postpartum hemorrhage was not significantly lower in our cohort. The primary perinatal composite outcome was significantly better in our cohort than in both arms of the ARRIVE trial (2.1 vs. 5.4% in the expectant group and 4.3% in the induction group). We did not record cases with an Apgar score ≤ 3 or hypoxic-ischemic encephalopathy. CONCLUSION In our cohort, expectant management in low-risk pregnancies with late preterm screening of feto-maternal well-being seemed to achieve better maternal and perinatal outcomes than a universal policy of induction at 39 weeks. The results of the ARRIVE trial should be carefully evaluated in different demographic and clinical settings and cannot be extended to the general population.

Abstract
In the context of SARS-CoV-2 pandemic, the hospital management of mother-infant pairs poses to obstetricians and neonatologists previously unmet challenges. In Lombardy, Northern Italy, 59 maternity wards networked to organise the medical assistance of mothers and neonates with suspected or confirmed SARS-CoV-2 infection. Six “COVID-19 maternity centres” were identified, the architecture and activity of obstetric and neonatal wards of each centre was reorganised, and common assistance protocols for the management of suspected and proven cases were formulated. Here, we present the key features of this reorganization effort, and our current management of the mother-infant dyad before and after birth, including our approach to rooming-in practice, breastfeeding and neonatal follow-up, based on the currently available scientific evidence. Considered the rapid diffusion of COVID-19 all over the world, we believe that preparedness is fundamental to assist mother-infant dyads, minimising the risk of propagation of the infection through maternity and neonatal wards.

Abstract
Photon upconversion based on sensitized triplet-triplet annihilation ( sTTA) is considered as a promising strategy for the development of light-managing materials aimed to enhance the performance of solar devices by recovering unused low-energy photons. Here, we demonstrate that, thanks to the fast diffusion of excitons, the creation of triplet pairs in metal-organic framework nanocrystals ( nMOFs) with size smaller than the exciton diffusion length implies a 100% TTA yield regardless of the illumination condition. This makes each nMOF a thresholdless, single-unit annihilator. We develop a kinetic model for describing the upconversion dynamics in a nanocrystals ensemble, which allows us to define the threshold excitation intensity Ithbox required to reach the maximum conversion yield. For materials based on thresholdless annihilators, Ithbox is determined by the statistical distribution of the excitation energy among nanocrystals. The model is validated by fabricating a nanocomposite material based on nMOFs, which shows efficient upconversion under a few percent of solar irradiance, matching the requirements of real life solar technologies. The statistical analysis reproduces the experimental findings, and represents a general tool for predicting the optimal compromise between dimensions and concentration of nMOFs with a given crystalline structure that minimizes the irradiance at which the system starts to fully operate.

Abstract
First described in 1965 as a specific antigen for cancer of the colon, CEA is now considered to be an antigen associated with many types of malignant neoplasia, although the CEA-Test's role in clinical routine has yet to be clearly defined. In the present study CEA levels in gastric juice were measured in subjects with gastric carcinoma (n = 25) and with benign gastric lesions (n = 171). CEA was significantly (p < 0.05) higher in patients with gastric carcinoma (GC) than in subjects with benign gastric lesions, other than chronic atrophic gastritis (CAG) associated with intestinal metaplasia (IM). In this latter condition CEA levels were similar to those in patients with GC. These results suggest that the assay of CEA in gastric juice could be included in the diagnostic program for gastric cancer and its precursors with the aim of assessing its utility as risk indicator in the management of precancerous conditions and lesion.

Abstract
INTRODUCTION Peri-implant breast seroma is a late clinical presentation of reconstructive surgery or augmentation mammoplasty with breast implants. Pre-operative cytological evaluation of the peri-implant breast seroma is a common clinical approach, showing mainly an inflammatory reaction or more rarely a breast implant-associated anaplastic large cell lymphoma. Herein, we reported the role of cytology in the evaluation of peri-implant breast seroma and its critical pre-operative implications. METHODS Eight cases of peri-implant breast seroma from files at Luigi Vanvitelli University were identified between January and December 2017. In all cases, seroma was aspirated; cytospins were performed and stained by Papanicolaou stain; finally, in all cases, a cell block was obtained for immunocytochemical evaluation and, in one case, for FISH to detect ALK1-gene translocation. RESULTS The median age of patients was 48 years and the mean time between the implant placement and the occurrence of peri-implant breast seroma was 18 months. Microscopic examination showed breast implant-associated anaplastic large cell lymphoma in one case, aspecific inflammatory reaction in six cases and silicon-associated reaction in one case. CONCLUSIONS Peri-implant breast seroma may be caused by several pathological conditions with different clinical behaviour. A proper cytological approach to peri-implant breast seroma allows a correct differential diagnosis between inflammatory conditions and breast implant-associated anaplastic large cell lymphoma and an appropriate management of the patient.

Abstract
The influence of the Mott physics on the doping-temperature phase diagram of copper oxides represents a major issue that is subject of intense theoretical and experimental effort. Here, we investigate the ultrafast electron dynamics in prototypical single-layer Bi-based cuprates at the energy scale of the O-2p→Cu-3d charge-transfer (CT) process. We demonstrate a clear evolution of the CT excitations from incoherent and localized, as in a Mott insulator, to coherent and delocalized, as in a conventional metal. This reorganization of the high-energy degrees of freedom occurs at the critical doping pcr ≈0.16 irrespective of the temperature, and it can be well described by dynamical mean field theory calculations. We argue that the onset of the low-temperature charge instabilities is the low-energy manifestation of the underlying Mottness that characterizes the p < pcr region of the phase diagram. This discovery sets a new framework for theories of charge order and low-temperature phases in underdoped copper oxides.

Abstract
Background Schwannoma and angiosarcoma are infrequent pathologies that have been rarely reported in the kidney. Angiosarcoma is an uncommon malignant tumor presenting a recognizable vascular differentiation. It can develop in any site but the most common locations include the skin, soft tissues, breast, bone, liver, and spleen while renal localization has been very rarely reported in the literature. Schwannoma is a benign peripheral nerve sheath tumor composed of cells with the immunophenotype and ultrastructural features of differentiated Schwann cells. It has a wide anatomical distribution but the most frequent locations include subcutaneous tissues of the extremities and the head and neck region and the retroperitoneal and mediastinal soft tissues. The occurrence of an angiosarcoma in a pre-existing schwannoma is an extremely rare event with <20 cases reported in worldwide literature. In the present study, a renal case of angiosarcoma arising in schwannoma is presented with a detailed review of the pertinent literature. Case Presentation A 56-year-old man was admitted with a few days history of lower back pain and hematuria. Abdominal ultrasound showed a mass inside the left renal medulla. Subsequent imaging investigations with computed tomography and magnetic resonance confirmed the presence of the lesion and showed a pulmonary metastasis. Conclusions The final histopathological examination led to the diagnosis of epithelioid angiosarcoma arising in a schwannoma. The patient came to death a few months later due to a massive hemothorax. To the best of our knowledge, the present is the first case of an angiosarcoma arising in a schwannoma of the kidney.

Abstract
Medulloblastomas (MBs) associated with the Wnt activation represent a subgroup with a favorable prognosis, but it remains unclear whether Wnt activation confers a less aggressive phenotype and/or enhances radiosensitivity. To investigate this issue, we evaluated the biological behavior of an MB cell line, UW228-1, stably transfected with human β-catenin cDNA encoding a nondegradable form of β-catenin (UW-B) in standard culture conditions and after radiation treatment. We evaluated the expression, transcriptional activity, and localization of β-catenin in the stably transfected cells using immunofluorescence and WB. We performed morphological analysis using light and electron microscopy. We then analyzed changes in the invasiveness, growth, and mortality in standard culture conditions and after radiation. We demonstrated that (A) Wnt activation inhibited 97 % of the invasion capability of the cells, (B) the growth of the UW-B cells was statistically significantly lower than that of all the other control cells (p < 0.01), (C) the mortality of irradiated UW-B cells was statistically significantly higher than that of the controls and their nonirradiated counterparts (p < 0.05), and (D) morphological features of neuronal differentiation were observed in the Wnt-activated cells. In tissue samples, the Ki-67 labeling index (LI) was lower in β-catenin-positive samples compared to non-β-catenin positive ones. The Ki-67 LI median (LI = 40) of the nuclear β-catenin-positive tumor samples was lower than that of non-nuclear β-catenin-positive samples (LI = 50), but the difference was not statistically significant. Overall, our data suggest that activation of the Wnt pathway reduces the proliferation and invasion of MBs and increases the tumor's radiosensitivity.

Abstract
The study evaluated the effect of a novel commercial preparation of natural blend of essential oils from basil, caraway, laurel, lemon, oregano, sage, tea, and thyme (Tecnaroma Herbal Mix PL) on growth performance, blood biochemistry, cecal morphology, and carcass quality of broilers. Six nutritionally adequate wheat and soybean-based diets were generated by the addition of Tecnaroma Herbal Mix PL at 0, 100, 200, 300, 400, and 500 g/t of feed. The diets were fed as crumbs in the starter phase (d 0–10) and as pellets during the grower (d 10–24) and finisher (d 24–42) phases. Nine hundred sixty 1-d-old chicks were allocated to the 6 dietary treatments each having 8 replicate pens with 20 birds per pen. The data obtained were analyzed using ANOVA with a P < 0.05 level of significance. Birds fed diets supplemented with Tecnaroma Herbal Mix PL had significantly heavier BW and higher (P < 0.05) weight gain and had improved (P < 0.05) feed to gain ratio compared with the control group during grower phase and overall performance. The blood biochemistry results showed no differences (P > 0.05) between treatments. The carcass weight, breast weight, and relative percentage of breast meat increased (P < 0.05) when diets were supplemented with Tecnaroma Herbal Mix PL compared with that from birds fed the control diet. The inclusion level of 300 g of Tecnaroma Herbal Mix PL/t of feed was optimum for enhancing breast meat yield and nutrient utilization as indicated by increased (P < 0.05) cecal villus surface area.

Abstract
The increasing use of multi-elementary techniques such as inductively coupled plasma mass spectrometer (ICP-MS), possibly in combination with dynamic reaction cell or other device, has greatly simplified the determination of trace elements in serum or plasma, whole blood and urine, even resorting to a phase of mineralization of the sample with microwave and teflon pressurized containers. This has made it necessary, however, an accurate control of interference, particularly polyatomic, using when possible, high-resolution ICP-MS, ICP-OES and ETA-AAS with electrothermal atomization. RE-VA study involved 162 subjects and has made available the reference values or background values for 42 elements in the matrix above. Physiological variables, life habits and food were also investigated. The aim is to implement the series through the sampling and analysis of similar types of samples in other Italian regions and countries in Europe and beyond. The data obtained allow to focus any inconsistencies for specific analytes and matrices, in order to identify critical variable attributable to both analytical and pre-analytical factors. For elements such as W, Ba, Cs, Pt, RE-VA study has revealed significant differences compared to other studies, and this is most likely to report high analytical sensitivity of DRC-ICP-MS as confirmed by comparative studies with Sector Field ICP-MS which provided matching values. It is also discussed the limitation of the use of VR for studies aimed at population groups living in industrial areas or where there are landfills, coal power plants and thermo incinerators.

Abstract
Environmental and biological monitoring performed in health care settings during a 14-year period allowed numerous data to be obtained by using the HPLC coupled with tandem mass spectrometry (HPLC-MS/MS). Data was stored in a specific data-base for the assessment of risk exposure to antineoplastic agents (CA). The strategy of analysis was based on the simultaneous determination of different active substances with a lower limit of quantification (LOQ) optimized in the range of sub-units of microg/L. In the present study, the MRM-ESI-MS/MS profiles of seven antineoplastic agents in both environmental and biological matrices are reported. These methods validated according to FDA guidelines allowed our lab to define a profile of antineoplastic agents that was representative of the four IARC classes, such as cyclophosphamide (group 1), cisplatin and doxorubicin (group 2A), daunorubicin (group 2B), 5-fluorouracil, ifosfamide (group 3), taxol, and gemcitabine (group 4). Moreover, contamination levels on a number of work surfaces and trends over a 14-year period are presented. The evaluation of occupational exposure to CA has been based on ALARA principle for most of the past decades but this principle is nowadays overwhelmed by the fast development of technology. The assessment of a possible in-take of CA in hospital personnel, when the sources of environmental contamination are identified, has become possible by the defining of a limit of exposure close to the limit of detection of the analytical method.

Abstract
The transcription factor Sox2 is essential for neural stem cells (NSC) maintenance in the hippocampus and in vitro. The transcription factor Emx2 is also critical for hippocampal development and NSC self-renewal. Searching for ‘modifier’ genes affecting the Sox2 deficiency phenotype in mouse, we observed that loss of one Emx2 allele substantially increased the telencephalic β-geo (LacZ) expression of a transgene driven by the 5′ or 3′ Sox2 enhancer. Reciprocally, Emx2 overexpression in NSC cultures inhibited the activity of the same transgene. In vivo, loss of one Emx2 allele increased Sox2 levels in the medial telencephalic wall, including the hippocampal primordium. In hypomorphic Sox2 mutants, retaining a single ‘weak’ Sox2 allele, Emx2 deficiency substantially rescued hippocampal radial glia stem cells and neurogenesis, indicating that Emx2 functionally interacts with Sox2 at the stem cell level. Electrophoresis mobility shift assays and transfection indicated that Emx2 represses the activities of both Sox2 enhancers. Emx2 bound to overlapping Emx2/POU-binding sites, preventing binding of the POU transcriptional activator Brn2. Additionally, Emx2 directly interacted with Brn2 without binding to DNA. These data imply that Emx2 may perform part of its functions by negatively modulating Sox2 in specific brain areas, thus controlling important aspects of NSC function in development.

Abstract
Lithium is the main therapeutic agent for the treatment of bipolar disorders but nerve cells are not the sole target of this drug. Indeed, lithium has been reported to target numerous cell types and to affect cell proliferation, differentiation and death. Lithium targets a variety of enzymes among which there is GSK-3beta and a number of cell responses elicited by lithium are mediated by the Wnt pathway that is involved in medulloblastoma (MB) pathogenesis. We studied the in vitro effects of lithium on two different MB cell lines: D283MED and DAOY. High doses of lithium inhibited GSK3-beta, decreased cell proliferation and induced non-apoptotic cell death in both cell lines independently by intracellular levels of beta-catenin that is consistently high only in D283MED. At clinical doses, the anti-neoplastic effects were observed only in this cell line, highlighting the importance of a specific molecular background in determining the target therapy response. In conclusion, lithium could be a promising drug in MB, but an accurate molecular profile predictive of drug response still needs to be clarified.

Abstract
Medulloblastoma (MB) is the most common brain malignancy in children. Whole neural axis irradiation is the treatment of choice, but it often results in long-term neurocognitive and developmental impairment. Only insights into MB biology will lead to improved therapeutic outcome. Wingless (WNT) signalling deregulation occurs in up to 25% of sporadic tumors, but the specific role of nuclear beta-catenin and its involvement in the radioresponse remains unsettled. Therefore we studied the gamma-radiation response of two MB cell lines from cellular and molecular points of view. Our data show that the p53 wild-type cell line is more sensitive to ionizing radiations (IR) than the p53 mutated line, but apoptosis is also induced in p53-mutated cells, suggesting an alternative p53-independent mechanism. In addition, this study is the first to demonstrate that gamma-rays trigger the WNT system in our in vitro models. Further studies are required to test if this could explain the radiosensitivity of MB and the favorable prognostic value of nuclear beta-catenin in this tumor.

Abstract
AIM Trace elements are involved in many metabolic processes. They circulate prevalently bound to protein. In literature few studies deal with metal metabolism in adult patients with proteinuria, so we decided to further investigate metal metabolism in proteinuric patients. METHODS We studied 27 patients (14 male, 13 female), mean age 61.6+/-17 years with different degrees of renal function, serum albumin and proteinuria. Metal concentrations of copper (Cu), zinc (Zn) and aluminum (Al) were measured in serum and urine. No patient had environmental exposure to these metals. RESULTS The serum Zn level was below the normal range in 11 patients. The serum Cu level was reduced in 5 patients. The Al serum level was elevated in 4 patients. Six patients had reduced and 6 patients had elevated Zn excretion. The urinary Cu excretion was elevated in 6 patients. The urinary Al excretion was elevated in 1 patient. Trace metal concentrations were related neither to renal function nor to total serum protein or albumin levels. Serum zinc was directly correlated with proteinuria and urinary zinc and negatively correlated with testosterone levels in both sexes. CONCLUSION Adult patients with proteinuria have several modification of trace metal concentration in serum and urine. Serum concentration of metals did not depend on renal function or serum protein levels. Urinary Zn excretion was directly related to proteinuria and serum Zn levels. A negative correlation between serum Zn levels and testosterone was found in both sexes. Renal failure reduced urinary excretion of Cu and Al.

Abstract
The wide use of barium (Ba), cesium (Cs), antimony (Sb) and tungsten (W) in many industrial and agricultural fields causes the increased release of these metals into the environment, laying the basis for health risk. To assess the exposure for the general population, the development of adequate and reliable analytical techniques becomes compulsory. This study refers to the quantification of urinary Ba, Cs, Sb and W levels by both quadrupole (Q) and sector field (SF) inductively coupled plasma mass spectrometry (ICP-MS). The two procedures were compared for their performances and their measurement uncertainties. The limits of detection were (Q and SF) 23.0 and 5.21 ng L(-1) for Ba; 21.1 and 7.52 ng L(-1) for Cs; 1.09 and 0.43 ng L(-1) for Sb; and 0.36 and 0.49 ng L(-1) for W. The trueness was better than 93.3% and the precision less than 12% for both techniques. Relative expanded uncertainties of the analytical procedures, at the median levels found in the general population, were below 5% for all the elements with both ICP-MS techniques. The uncertainties related to the calibration and repeatability were the parameters most influencing the final analytical performance. The urinary median values observed in healthy subjects from central Italy were 1146, 4301, 60.8 and 48.5 ng L(-1) for Ba, Cs, Sb and W, respectively.
