Abstract
The aim of this study was to evaluate the effect of possible endocrine disruptors in surface and wastewater using a cell proliferation assay in an estrogen-responsive cell line (MCF-7). This study was conducted in the Sinos River (Brazil). The residual water was collected from a Pilot Treatment Plant (using Typha domingensis) and surface waters of the Luis Rau stream, the Sinos River, and the Water Treatment Station (WTS). After exposures (24-120 h), a Sulforhodamine B assay was performed to determine the proliferation rate. The higher increase in proliferation rate was observed with the Luiz Rau stream and the sewage treated by macrophytes in a flotation filter. The results from WTS water remained with a proliferation rate similar to the negative control at all times, suggesting that the conventional treatment is partially effective for the withdrawal of endocrine-disrupting agents. The study demonstrated the efficiency of the MCF-7 line in assessing endocrine disruption caused by wastewater and surface water samples. Our results indicate that conventional water treatment can partially remove the polluting load of endocrine disruptors, minimizing their environmental and public health impacts. Besides, it demonstrates the need to expand sanitary services to improve the population's quality of life.

Abstract
OBJECTIVES A previous single-country pilot study indicated serum anti-GM2 and anti-GA1 anti-glycolipid antibodies as potential biomarkers for acute canine polyradiculoneuritis. This study aims to validate these findings in a large geographically heterogenous cohort. MATERIALS AND METHODS Sera from 175 dogs clinically diagnosed with acute canine polyradiculoneuritis, 112 dogs with other peripheral nerve, cranial nerve or neuromuscular disorders and 226 neurologically normal dogs were screened for anti-glycolipid antibodies against 11 common glycolipid targets to determine the immunoglobulin G anti-glycolipid antibodies with the highest combined sensitivity and specificity for acute canine polyradiculoneuritis. RESULTS Anti-GM2 anti-glycolipid antibodies reached the highest combined sensitivity and specificity (sensitivity: 65.1%, 95% confidence interval 57.6 to 72.2%; specificity: 90.2%, 95% confidence interval 83.1 to 95.0%), followed by anti-GalNAc-GD1a anti-glycolipid antibodies (sensitivity: 61.7%, 95% confidence interval 54.1 to 68.9%; specificity: 89.3%, 95% confidence interval 82.0 to 94.3%) and these anti-glycolipid antibodies were frequently present concomitantly. Anti-GA1 anti-glycolipid antibodies were detected in both acute canine polyradiculoneuritis and control animals. Both for anti-GM2 and anti-GalNAc-GD1a anti-glycolipid antibodies, sex was found a significantly associated factor with a female to male odds ratio of 2.55 (1.27 to 5.31) and 3.00 (1.22 to 7.89), respectively. Anti-GalNAc-GD1a anti-glycolipid antibodies were more commonly observed in dogs unable to walk (OR 4.56, 1.56 to 14.87). CLINICAL SIGNIFICANCE Anti-GM2 and anti-GalNAc-GD1a immunoglobulin G anti-glycolipid antibodies represent serum biomarkers for acute canine polyradiculoneuritis.

Abstract
Background This study aims to propose an initial development of the FACT-Liver Transplant (FACT-LT) scale to assess the major physical and emotional concerns of patients before and after Orthotopic Liver transplant (OLT) due to acute and chronic liver failure and hepatocellular carcinoma. Methods The FACT-LT was developed in two phases. In Phase I, items were generated: 1) through interviews with 10 OLT experts and 15 candidates for or recipients of both oncological and non-oncological OLT which identified relevant topics; 2) from the FACIT item bank. In Phase II, a questionnaire to assess item frequency, applicability, and comprehension was administered to 20 OLT experts and, to assess item difficulty, embarrassment and content irrelevance, to 30 transplant recipients or candidate patients (15 oncological, 15 non-oncological). Results In Phase I, 44 items were formulated/reviewed, and 30 items were maintained. All the healthcare professionals interviewed rejected the recommendation to develop two different modules for cancer and non-cancer patients. In Phase II, the majority of the experts and patients expressed an overall satisfaction with the questionnaire, indicating that the items were relevant, comprehensible and not embarrassing (range 75% - 99%). The first version of the FACT-LT includes 28 items defining four QOL domains: 5 items relating to Physical Well-Being, 8 to Functional Well-Being, 13 to Emotional Well-Being, and 2 to Social/Family Well-Being. Conclusion The preliminary results obtained were promising; however further studies are needed, in order to proceed with a FACT-LT validation process.

Abstract
Glioblastoma is the most common primary malignant brain tumor. Despite treatments combining excisional surgery, chemotherapy, and radiotherapy, overall survival remains low and the incidence of tumor recurrence remains high. Advances in the understanding of the disease, particularly its molecular biology and the mechanisms of action of systemic and radiotherapeutic treatments, as well as the development of image-guided surgical techniques, offer hope for the control of this hitherto incurable disease.

Abstract
BACKGROUND AND PURPOSE The recent SARS-CoV-2 pandemic has posed multiple challenges to the practice of clinical neurology including recognition of emerging neurological complications and management of coexistent neurological diseases. In a fast-evolving pandemic, evidence-based studies are lacking in many areas. This paper presents European Academy of Neurology (EAN) expert consensus statements to guide neurologists caring for patients with COVID-19. METHODS A refined Delphi methodology was applied. In round 1, statements were provided by EAN scientific panels (SPs). In round 2, these statements were circulated to SP members not involved in writing them, asking for agreement/disagreement. Items with agreement >70% were retained for round 3, in which SP co-chairs rated importance on a five-point Likert scale. Results were graded by importance and reported as consensus statements. RESULTS In round one, 70 statements were provided by 23 SPs. In round two, 259/1061 SP member responses were received. Fifty-nine statements obtained >70% agreement and were retained. In round three, responses were received from 55 co-chairs of 29 SPs. Whilst general recommendations related to prevention of COVID-19 transmission had high levels of agreement and importance, opinion was more varied concerning statements related to therapy. CONCLUSION This is the first structured consensus statement on good clinical practice in patients with neurological disease during the COVID-19 pandemic that provides immediate guidance for neurologists. In this fast-evolving pandemic, a rapid response using refined Delphi methodology is possible, but guidance may be subject to change as further evidence emerges.

Abstract
OBJECTIVE This observational study aims to analyze the quality of life of the administrative/technical employees of the University of Ferrara and its relationship with sleep quality, chronotype, and family components. PATIENTS AND METHODS We invited all employees (528) to fill a data collection form (age, gender, education level, number of family components, being caregiver and job-related factors) and 3 anonymous questionnaires (VR-12 Health-Related Quality of Life, Pittsburgh Sleep Quality Index, and Morningness-Eveningness Questionnaire). RESULTS Out of 323 respondents, 72.5% were female, 76.4% had an age between 41-60 years old, 63.8% had a university degree, and 67.5% an administrative profile. Considering family-related characteristics: 81.1% of respondents lived with ≥2 people, 35.3% had children, and 31.9% declared to be caregiver of a family member, not necessarily co-housing. Most of the employees resulted to be Morning-type (48.6%) and Intermediate-type (46.8%), with a very limited group of Evening-types (4.6%). Quality of sleep resulted to be the main factor affecting the health-related quality of life. Near half of our sample had poor sleep quality (49.2%; 95% CI: 43.6-54.8%). PSQI score resulted significantly higher for people who were caregivers of a familiar (7.0 ± 3.6 vs. 6.1 ± 3.6, p=0.022). Family size and being caregiver of a familiar resulted in significant factors for sleep quality, and indirectly for health-related quality of life. CONCLUSIONS The quality of sleep is the most influencing parameter of the workers' quality of life. Family size and being caregiver of a family member indirectly affect the quality of life by influencing sleep quality. Appropriate consideration and management of these aspects in the working context could improve workers' well-being.

Abstract
The aggregation properties of semaglutide, a lipidated peptide drug agonist of the Glucagon-like peptide 1 receptor recently approved for the treatment of type 2 diabetes, have been investigated by spectroscopic techniques (UV-Vis absorption, steady-state and time-resolved fluorescence, and electronic circular dichroism) and molecular dynamics simulations. We show that in the micromolar concentration region, in aqueous solution, semaglutide is present as monomeric and dimeric species, with a characteristic monomer-to-dimer transition occurring at around 20 μM. The lipid chain stabilizes a globular morphology of the monomer and dimer species, giving rise to a locally well-defined polar outer surface where the lipid and peptide portions are packed to each other. At very long times, these peptide clusters nucleate the growth of larger aggregates characterized by blue luminescence and a β-sheet arrangement of the peptide chains. The understanding of the oligomerization and aggregation potential of peptide candidates is key for the development of long acting and stable drugs.

Abstract
Background and purpose Although the main clinical features of COVID‐19 infection are pulmonary, several associated neurological signs, symptoms and diseases are emerging. The incidence and characteristics of neurological complications are unclear. For this reason, the European Academy of Neurology (EAN) core COVID‐19 Task Force initiated a survey on neurological symptoms observed in patients with COVID‐19 infection. Methods A 17‐question online survey was made available on the EAN website and distributed to EAN members and other worldwide physicians starting on 9 April 2020. Results By 27 April 2020, proper data were collected from 2343 responders (out of 4199), of whom 82.0% were neurologists, mostly from Europe. Most responders (74.7%) consulted patients with COVID‐19 mainly in emergency rooms and in COVID‐19 units. The majority (67.0%) had evaluated fewer than 10 patients with neurological manifestations of COVID‐19 (neuro COVID‐19). The most frequently reported neurological findings were headache (61.9%), myalgia (50.4%), anosmia (49.2%), ageusia (39.8%), impaired consciousness (29.3%) and psychomotor agitation (26.7%). Encephalopathy and acute cerebrovascular disorders were reported at 21.0%. Neurological manifestations were generally interpreted as being possibly related to COVID‐19; they were most commonly recognized in patients with multiple general symptoms and occurred at any time during infection. Conclusion Neurologists are currently and actively involved in the management of neurological issues related to the COVID‐19 pandemic. This survey justifies setting up a prospective registry to better capture the prevalence of patients with neuro COVID‐19, neurological disease characteristics and the contribution of neurological manifestations to outcome.

Abstract
Background:It is currently not known if TNF or IL-17A inhibitors have an impact on immune cell frequencies in axial Spondyloarthritis (AxSpA). This question is important to understand the impact of biologics on the immune system. Data from clinical trials didn’t show significant modification on immune cells and especially on lymphocytes. But regarding the risk of infections linked to these treatments lymphocyte cell subsets are certainly disturbed. Moreover, biologics could affect subsets of cells with an unusual phenotype.Objectives:To identify the phenotype of cell subsets affected by biologics.Methods:We used an “unsupervised approach” to analyze CD4+ T cells and CD8+T cells subsets. Contrary to a “supervised approach”, this strategy takes advantages of the fluorescence emitted by all of the surface markers used to characterize the cells at the same time. The objective was on the one hand to overcome statistical problems related to the number of patients and the repetition of the tests and on the other hand to increase the sensitivity of the analysis by identifying and analyzing new cell populations. The first step was to cluster the cells based on a selection of 12 T cells markers characteristic of the classical cell subsets and the stage of maturation to obtain cell clusters with a phenotype based on the combination of these 12 markers. Then, we were able to describe “a posteriori” the change of frequency of the clusters identified. The second step was to create a visualization of the cells affected to confirm their existence in a classical flow cytometry gate. With this pipeline, we analyzed CD4 and CD8 T cells isolated from a group of AxSpA patients (n=7) before and after 3 months of TNF therapy and a group of patients (n=6) before and after 4 months of IL-17A therapy.Results:We observed that after biologics CD4 and CD8 T cells frequencies did not change but there was a redistribution of the different clusters analyzed. Specifically, we identified for CD4+T cells after anti TNF treatment an increase of 2 clusters (CD4+CD27+CD45RA+Va7.2intCD161int and CD4+CD27-CD45RA-CCR6+CD161int) and a decrease of 3 clusters (CD4+CD27+CD45RA+CRTH2intCD161int, CD4+ CD27+CD45RA+CXCR3+, CD4+CD27+CD45RA+gdint CD161int) and for CD8+T cells a decrease of 1 cluster after treatment (CD8+ CD27+CD45RA+CD161+CXCR3+) and an increase of 1 cluster (CD8+ CD27+CD45RA+). The clusters affected by anti-IL-17A therapy were different. For CD4+T cells, we identified a decrease of 2 clusters (CD4+CD27+CD45RA+CXCR5+ CD161+ and CD4+CD27+CD45RA- CXCR3+CCR6+CD161+) and an increase of 2 clusters (CD4+CD27+CD45RA+gdintCD161+, CD4+CD27+ CRTH2intCCR6+) and for CD8+T cells a decrease of 1 cluster (CD8+CD27+CD45RA+ CXCR3+CRTH2intCD161int) and an increase of 1 cluster (CD8+CD27+CD45RA+CXCR3intCD161-).Conclusion:We identified 5 different clusters in CD4+T cells affected by anti TNF and 4 by anti-IL-17A. We identified 2 clusters in CD8+T cells affected by anti TNF and 2 by anti-IL-17A. The phenotypes of these clusters were unexpected and raised new questions about the effect of biologics in AxSpA. We were also able to create a visualization of these cells affected by biologics in a “classic gating view” which will help us to perform scRNAseq. With this unique approach, we show an impact of biologics on the frequency of very specific subset of CD4+ and CD8+ T cells in AxSpAFigure 1.Disclosure of Interests:None declared

Abstract
PURPOSE This study aims to explore the relation between the dimension of fear of cancer recurrence (FCR) in haematological cancer patients relapse-free for at least 2 years and socio-demographic, related to the disease, psychological and existential factors. METHODS A sample of 75 haematological cancer patients agreed to participate in the study through a self-reported online questionnaire (51.9% males). A total of 70.1% had a low recurrence risk. The questionnaire included socio-demographic (gender, age, civil status, level of education and number of children), related to the disease (diagnosis, therapeutic line and years since diagnosis), psychological (anxiety and depression), existential (purpose in life; PIL) factors and Fear of Cancer Recurrence Concerns Inventory (FCRI). Simple and multiple linear regressions were conducted for the analyses, and we performed some preliminary analysis on the reliability of the FCRI. FINDINGS A total of 53.3% of participants showed clinical levels of FCR on the severity dimension, which was higher than found in previous research in other cancer patients. The coping strategies, triggers, severity and psychological distress dimensions showed higher mean values. Women, patients with indolent non-Hodgkin lymphomas, years since diagnosis, anxiety and purpose in life are significantly related to one or more dimensions of FCRI. IMPLICATIONS It is important that the clinicians have at their disposal multiple possibilities to help patients cope with haematological cancer. If future research will confirm the results of this study, the negative correlation between FCR and PIL can suggest indications for planning interventions based on a salutogenic approach.

Abstract
Characterizing functional trait variation and covariation, and its drivers, is critical to understand the response of species to changing environmental conditions. Evolutionary and environmental factors determine how traits vary among and within species at multiple scales. However, disentangling their relative contribution is challenging and a comprehensive trait-environment framework addressing such questions is missing in lichens. We investigated the variation in nine traits related to photosynthetic performance, water use and nutrient acquisition applying phylogenetic comparative analyses in lichen epiphytic communities on beech across Europe. These poikilohydric organisms offer a valuable model owing to their inherent limitations to buffer contrasting environmental conditions. Photobiont type and growth form captured differences in certain physiological traits whose variation was largely determined by evolutionary processes (i.e. phylogenetic history), although the intraspecific component was non-negligible. Seasonal temperature fluctuations also had an impact on trait variation, while nitrogen content depended on photobiont type rather than nitrogen deposition. The inconsistency of trait covariation among and within species prevented establishing major resource use strategies in lichens. However, we did identify a general pattern related to the water-use strategy. Thus, to robustly unveil lichen responses under different climatic scenarios, it is necessary to incorporate both among and within-species trait variation and covariation.

Abstract
We discuss the diagnostic workup of a 62 year old woman without any significant past medical history. We take this opportunity to point out three aspects : 1. The necessary contextualization of the whole process allowing to avoid unrealistic differentials; 2. The requirement to prioritize the diagnostic tests as a function of their expected contribution to the diagnosis, their invasive characteristic and their availability, including their cost and 3. The evolving character of the diagnostic process that, if needed, has to be reconsidered to integrate the information obtained from the first diagnostic tests and the evolution of the patient.

Abstract
PURPOSE Dup15q syndrome is a rare genetic disease with a fairly nonspecific phenotype, clinical heterogeneity, and a wide spectrum of severity. However, no formal characterization has been attempted to select clusters of symptoms, signs and instrumental tests, to be used in the differential diagnosis with other neurodevelopmental disorders. Thus, our purpose was to identify symptoms, signs and instrumental findings, singly or in various combinations, favoring the early diagnosis of the Dup15q syndrome and the indication for genetic testing. METHODS 25 patients with Dup15q syndrome and 25 age and sex matched controls with other neurodevelopmental disorders were the study population. Patients' history, clinical and instrumental assessment were examined by five expert child neurologists blind to the genetic diagnosis. Each rater was asked to make the diagnosis in three subsequent steps: 1. Revision of the medical records; 2. Examination of the videorecorded clinical findings; 3. Assessment of the instrumental tests. Inter-rater agreement was measured with the Kendall's coefficient of concordance) and the Kappa statistic. Sensitivity, specificity and predictive values for symptoms, signs and instrumental findings, singly or in various combinations, were measured. RESULTS The Kendall's coefficient for the diagnosis of Dup15q syndrome was 0.43 at step 1 was 0.43, at step 2 was 0.42, at step 3. Patients with past feeding difficulties, hypotonia during the neonatal period, and epilepsy had >80 % probability of having the Dup15q syndrome. CONCLUSION Feeding difficulties, hypotonia and epilepsy, though unspecific, can be used as signals of Dup15q syndrome and focused search of genetic abnormalities.

Abstract
Epilepsy is the most common chronic neurological disorder in dogs. Approximately 20-30% of dogs do not achieve satisfactory seizure control with two or more anti-epileptic drugs at appropriate dosages. This condition, defined as refractory epilepsy, is a multifactorial condition involving both acquired and genetic factors. The P glycoprotein might play and important role in the pathophysiological mechanism and it is encoded by the ABCB1 gene. An association between a single nucleotide variation of the ABCB1 gene (c.-6-180T>G) and phenobarbital resistance has previously been reported in a Border collie population with idiopathic epilepsy. To date, the presence and relevance of this polymorphism has not been assessed in other breeds. A multicentre retrospective, case-control study was conducted to investigate associations between ABCB1 c.-6-180T>G, clinical variables, and refractoriness in a multi-breed population of dogs with refractory idiopathic epilepsy. A secondary aim was to evaluate the possible involvement of the ABCB1 c.-6-180T>G single nucleotide variation this population. Fifty-two refractory and 50 responsive dogs with idiopathic epilepsy were enrolled. Of these, 45 refractory and 50 responsive (control) dogs were genotyped. The G allele was found in several breeds, but there was no evidence of association with refractoriness (P=0.69). The uncertain role of the c.-6-180T>G variation was further suggested by an association between the T/T genotype with both refractoriness and responsiveness in different breeds. Furthermore, high seizure density (cluster seizure) was the main clinical risk factor for refractory idiopathic epilepsy (P=0.003).

Abstract
PURPOSE This paper explores the feasibility of a new therapy for the treatment of hypospadias patients. Hypospadias is a very common congenital malformation of male genitals, with very high rate of recurrences after surgery. The field of regenerative medicine, which offers innovative solutions for many pathologies, still does not offer reliable solution for this pathology. Here, we propose quality, safety, and clinical feasibility assessment for an oral mucosa advanced therapy medicinal product (ATMP) grown on a biocompatible scaffold for a clinical study on urethral reconstruction of hypospadias patients. METHODS Urethral and oral mucosal epithelia from donor biopsies were cultivated between two fibrin layers, under clinical-grade conditions for cell and tissue characterization and comparison, aimed at tissue engineering. In addition, single-clone analyses were performed to analyze gene expression profiles of the two epithelia by microarray technology. RESULTS Oral mucosa appeared suitable for urethral reconstruction. The resulting ATMP was proven to maintain stem cells and regenerative potency. The preclinical safety studies were performed on human tissues to assess abnormalities and tumorigenicity, and confirmed the safety of the ATMP. Finally, the patient selection and the clinical protocol for the upcoming clinical trial were defined. CONCLUSIONS Against this backdrop, in this paper, we are proposing a new reproducible and reliable ATMP for the treatment of hypospadias.

Abstract
Evidence is mounting that the small bodies of our Solar System, such as comets and asteroids, have at least partially inherited their chemical composition from the first phases of the Solar System formation. It then appears that the molecular complexity of these small bodies is most likely related to the earliest stages of star formation. It is therefore important to characterize and to understand how the chemical evolution changes with solar-type protostellar evolution. We present here the Large Program "Astrochemical Surveys At IRAM" (ASAI). Its goal is to carry out unbiased millimeter line surveys between 80 and 272 GHz of a sample of ten template sources, which fully cover the first stages of the formation process of solar-type stars, from prestellar cores to the late protostellar phase. In this article, we present an overview of the surveys and results obtained from the analysis of the 3 mm band observations. The number of detected main isotopic species barely varies with the evolutionary stage and is found to be very similar to that of massive star-forming regions. The molecular content in O- and C- bearing species allows us to define two chemical classes of envelopes, whose composition is dominated by either a) a rich content in O-rich complex organic molecules, associated with hot corino sources, or b) a rich content in hydrocarbons, typical of Warm Carbon Chain Chemistry sources. Overall, a high chemical richness is found to be present already in the initial phases of solar-type star formation.

Abstract
Sperm RNA is a sensitive monitoring endpoint for male reproductive toxicants, and a potential biomarker to assess male infertility and sperm quality. However, isolation of sperm RNA is a challenging procedure due to the heterogeneous population of cells present in the ejaculate, the low yield of RNA per spermatozoon, and the absence of 18S and 28S ribosomal RNA subunits. The unique biology of spermatozoa has created some uncertainty in the field about RNA isolation methods, indicating the need for rigorous quality control checks to ensure reproducibility of data generated from sperm RNA. Therefore, we developed a reliable and effective protocol for RNA isolation from rat and human spermatozoa that delivers highly purified and intact RNA, verified using RNA-specific electrophoretic chips and molecular biology approaches such as RT-PCR and Western blot analysis. The sperm RNA isolation technique was optimized using rat spermatozoa and then adapted to human spermatozoa. Three steps in the sperm isolation procedure, epididymal fluid collection, sperm purification, and spermatozoon RNA extraction, were evaluated and assessed. The sperm RNA extraction methodology consists of collection of rat epididymal fluid with repeated needle punctures of the epididymis, somatic cell elimination using detergent-based somatic cell lysis buffer (SCLB) and the use of RNA isolation Kit. Rat sperm heads are more resistant to disruption than human spermatozoa, necessitating the addition of mechanical lysis with microbeads and heat in the rat protocol, whereas the human sperm protocol only required lysis buffer. In conclusion, this methodology results in reliable and consistent isolation of high-quality sperm RNA. Using this technique will aid in translation of data collected from animal models, and reproducibility of clinical assessment of male factor fertility using RNA molecular biomarkers.

Abstract
Primary myelofibrosis (PMF) is a myeloproliferative neoplasm characterized by hyperplastic megakaryopoiesis and myelofibrosis. We recently described the upregulation of MAF (v-maf avian musculoaponeurotic fibrosarcoma oncogene homolog) in PMF CD34+ hematopoietic progenitor cells (HPCs) compared to healthy donor. Here we demonstrated that MAF is also upregulated in PMF compared with the essential thrombocytemia (ET) and polycytemia vera (PV) HPCs. MAF overexpression and knockdown experiments shed some light into the role of MAF in PMF pathogenesis, by demonstrating that MAF favors the megakaryocyte and monocyte/macrophage commitment of HPCs and leads to the increased expression of proinflammatory and profibrotic mediators. Among them, we focused our further studies on SPP1 and LGALS3. We assessed SPP1 and LGALS3 protein levels in 115 PMF, 47 ET and 24 PV patients plasma samples and we found that SPP1 plasma levels are significantly higher in PMF compared with ET and PV patients. Furthermore, in vitro assays demonstrated that SPP1 promotes fibroblasts and mesenchymal stromal cells proliferation and collagen production. Strikingly, clinical correlation analyses uncovered that higher SPP1 plasma levels in PMF patients correlate with a more severe fibrosis degree and a shorter overall survival. Collectively our data unveil that MAF overexpression contributes to PMF pathogenesis by driving the deranged production of the profibrotic mediator SPP1.

Abstract
The Sinos River is one of the most polluted rivers in Brazil. The purpose of this work was to monitor the presence of some pesticides and hydrocarbons as well as the genotoxic and cytotoxic potential on HEp-2 cells from water samples collected at seven sites in the Sinos River Basin (SRB), southern Brazil. Nine samples were taken from the three main rivers in the SRB and used as a solution to dilute the HEp-2 cell culture medium after microfiltration. Twenty-four pesticides and 19 hydrocarbons were measured. Cytotoxicity was assessed by methyl thiazolyl tetrazolium (MTT) and neutral red (NR) assays, in which cells were exposed to different concentrations of the water samples for 24 h. Genotoxicity of the microfiltrated raw water samples was assessed by comet assay after 6 and 24 h of exposure. Among the chemicals analyzed, only the 2,4-D, dichloromethane, tetrachloroethene, chloroform, bromodichloromethane, styrene, and toluene were detected, but they were all lower than the limit established by Brazilian regulations. Twenty samples from a total of 60 had a cytotoxic effect in the MTT assay and 30 in the NR assay. The comet assay indicated the presence of genotoxic substances in the water at the seven locations monitored. Temporal and spatial variation was observed in the cytotoxicity and genotoxicity assays. Results indicated that the water in all stretches of the SRB is contaminated and it can cause harmful effects to humans and to the aquatic biota. This HEp-2 cell-line approach can be an additional tool for environmental monitoring.

Abstract
Transport properties of 3D scaffolds under fluid flow are critical for tissue development. Computational fluid dynamics (CFD) models can resolve 3D flows and nutrient concentrations in bioreactors at the scaffold-pore scale with high resolution. However, CFD models can be formulated based on assumptions and simplifications. μ-Particle image velocimetry (PIV) measurements should be performed to improve the reliability and predictive power of such models. Nevertheless, measuring fluid flow velocities within 3D scaffolds is challenging. The aim of this study was to develop a μPIV approach to allow the extraction of velocity fields from a 3D additive manufacturing scaffold using a conventional 2D μPIV system. The μ-computed tomography scaffold geometry was included in a CFD model where perfusion conditions were simulated. Good agreement was found between velocity profiles from measurements and computational results. Maximum velocities were found at the centre of the pore using both techniques with a difference of 12% which was expected according to the accuracy of the μPIV system. However, significant differences in terms of velocity magnitude were found near scaffold substrate due to scaffold brightness which affected the μPIV measurements. As a result, the limitations of the μPIV system only permits a partial validation of the CFD model. Nevertheless, the combination of both techniques allowed a detailed description of velocity maps within a 3D scaffold which is crucial to determine the optimal cell and nutrient transport properties.

Abstract
BACKGROUND Nearly 10% of all cases of cutaneous melanoma (CM) occur in patients with a personal or family history of the disease. OBJECTIVES To obtain information about genetic predisposition to CM in Ticino, the southern region of Switzerland, a zone with moderate-to-high CM incidence. METHODS We identified germline mutations in highly CM-associated genes (CDKN2A and CDK4) and low/medium-penetrance variants (MC1R and MITF) in patients with multiple primary CMs or individuals with one or more CM and a positive family history for CM or pancreatic cancer among first- or second-degree relatives. Healthy blood donors (n = 146) were included as a control group. RESULTS From July 2010 to July 2012, 57 patients (41 pedigrees) were included. Twenty-six were melanoma-prone families (with at least two cases) and 15 had multiple CMs. Pancreatic cancer was found in six families. The CDKN2A mutation p.V126D was identified in seven patients (four families) with a founder effect, whereas CDKN2A A148T was detected in seven cases (five families) and seven healthy donors (odds ratio 2·76, 95% confidence interval 0·83-9·20). At least one MC1R melanoma-associated polymorphism was detected in 32 patients (78%) and 97 healthy donors (66%), with more than one polymorphism in 12 patients (29%) and 25 healthy donors (17%). The MITF variant p.E318K was identified in four patients from three additional pedigrees (7%) and one healthy control (0·7%). CONCLUSIONS Inclusion criteria for the Ticino population for genetic assessment should follow the rule of two (two affected individuals in a family or a patient with multiple CMs), as we detected a CDKN2A mutation in almost 10% of our pedigrees (four of 41), MITF p.E318K in 7% (three of 41) and a higher number of MC1R variants than in the control population.

Abstract
AIMS Human cytomegalovirus (HCMV) is a ubiquitous beta human herpesvirus able to influence infected cell survival and proliferation and to modulate the host immune response. As there is accumulating evidence that HCMV is detected in primary intracranial astrocytic tumours, in this study we looked for the presence of HCMV in intracranial tumours and tried to correlate this eventual presence with the anti-HCMV systemic immunoreactivity and with the detection of HCMV in peripheral blood. METHODS In this study, we analysed 43 glioblastomas (GBM), 14 oligodendrogliomas (OL) and 20 meningiomas (MG) by immunofluorescence (IF) targeting HCMV immediate early antigen (IE1) and by nested PCR (nPCR) amplifying HCMV glycoprotein B (gB). RESULTS Detection of IE1 by IF showed the presence of HCMV in 70% of GBM, 57% of OL and 85% of MG, in contrast to gB nPCR, which detected HCMV in only 50% of GBM, 38% of OL and 46% of MG. Unexpectedly, HCMV DNA and antigens were detected within GBM, OL and MG of patients that exhibit negative viral serology. More surprisingly, PCR on the peripheral blood did not detect HCMV in patients with a HCMV-positive tumour. CONCLUSIONS Our results are in agreement with previous observations demonstrating HCMV in glial tumours and highlight the presence of HCMV in meningiomas. We also showed that anti-HCMV specific systemic immunoreactivity and detection of HCMV in peripheral blood are not predictive of HCMV presence in primary intracranial tumours.

Abstract
Cellular mechanical properties constitute good markers to characterize tumor cells, to study cell population heterogeneity and to highlight the effect of drug treatments. In this work, we describe the fabrication and validation of an integrated optofluidic chip capable of analyzing cellular deformability on the basis of the pressure gradient needed to push a cell through a narrow constriction. We demonstrate the ability of the chip to discriminate between tumorigenic and metastatic breast cancer cells (MCF7 and MDA-MB231) and between human melanoma cells with different metastatic potential (A375P and A375MC2). Moreover, we show that this chip allows highlighting the effect of drugs interfering with microtubule organization (paclitaxel, combretastatin A-4 and nocodazole) on cancer cells, which leads to changes in the pressure-gradient required to push cells through the constriction. Our single-cell microfluidic device for mechanical evaluation is compact and easy to use, allowing for an extensive use in different laboratory environments.

Abstract
OBJECTIVES Clinical predictors of falls in patients with Parkinson disease (PD) are fairly inaccurate. Stabilometric measures appear useful in investigating the relationship between balance, sensory disturbance, and falls. The aim of the study was to identify the best combination of clinical and stabilometric tests to predict falls prospectively. MATERIALS & METHODS Fifty-three consecutive subjects with PD or parkinsonisms at risk of falls were included and followed for 6 months. Clinical variables were used as fall predictors: the Unified Parkinson Disease's Rating Scale (motor section) and the Longitudinal Aging study Amsterdam Physical Activity Questionnaire (LAPAQ). Variables from stabilometric platform underwent a principal component analysis. Multivariate logistic models were used to predict fallers using fall status (fallers: 1 + falls; recurrent fallers: 2 + falls) as dependent variable. RESULTS Seven patients were lost to follow up, leaving 46 evaluable subjects. Of these, 32 (70%) were fallers and 22 (48%) were recurrent fallers. The only variable predicting fallers was the LAPAQ (odd ratio [OR] 0.99 (95% confidence interval [CI] 0.98-1.00); accuracy 71.7%; sensitivity 87.5%; specificity 35.7%). For recurrent fallers, Factor 2 (body sway velocity) (OR 2.37; 95% CI 1.01-5.58) and, in part, LAPAQ (OR 0.99; 95% CI 0.98-1.00) retained significance in the multivariate model, showing an accuracy of 76.9%, a sensitivity of 77.8%, and a specificity of 76.2%. CONCLUSIONS A combination of clinical and instrumental tools is useful to identify fallers in PD or parkinsonisms. Body sway velocity and ability to perform the activities of daily living are the best predictors of recurrent falls.

Abstract
We report the diagnostic workup of a 75-year old woman seen in the outpatient clinic and complaining of a very common symptom that is walking difficulty and falls. We stress the complexity of the clinical examination and of the pathophysiology of equilibrium and gait disorders. They are numerous aetiologies that are very often associated in elderly patients. The therapeutic approach is necessarily multidisciplinary, both medical and paramedical. In the particular case of the patient illustrated in this vignette, the diagnosis was myofibrillar myopathy, a rare and recently described muscle disease. This is the occasion to stress that for many rare disorders, it is the disease, but not the signs or symptoms, which is rare.
