Abstract
Colorectal cancer (CRC) tumors are composed of heterogeneous and plastic cell populations, including a pool of cancer stem cells that express LGR5. Whether these distinct cell populations display different mechanical properties, and how these properties might contribute to metastasis is poorly understood. Using CRC patient derived organoids (PDOs), we find that compared to LGR5- cells, LGR5+ cancer stem cells are stiffer, adhere better to the extracellular matrix (ECM), move slower both as single cells and clusters, display higher nuclear YAP, show a higher survival rate in response to mechanical confinement, and form larger transendothelial gaps. These differences are largely explained by the downregulation of the membrane to cortex attachment proteins Ezrin/Radixin/Moesin (ERMs) in the LGR5+ cells. By analyzing single cell RNA-sequencing (scRNA-seq) expression patterns from a patient cohort, we show that this downregulation is a robust signature of colorectal tumors. Our results show that LGR5- cells display a mechanically dynamic phenotype suitable for dissemination from the primary tumor whereas LGR5+ cells display a mechanically stable and resilient phenotype suitable for extravasation and metastatic growth.

Abstract
Tumor secreted extracellular vesicles (EVs) are potent intercellular signaling platforms. They are responsible for the accommodation of the premetastatic niche (PMN) to support cancer cell engraftment and metastatic growth. However, complex cancer cell composition within the tumor increases also the heterogeneity among cancer secreted EVs subsets, a functional diversity that has been poorly explored. This phenomenon is particularly relevant in highly plastic and heterogenous triple-negative breast cancer (TNBC), in which a significant representation of malignant cancer stem cells (CSCs) is displayed. Herein, we selectively isolated and characterized EVs from CSC or differentiated cancer cells (DCC; EVsCSC and EVsDCC , respectively) from the MDA-MB-231 TNBC cell line. Our results showed that EVsCSC and EVsDCC contain distinct bioactive cargos and therefore elicit a differential effect on stromal cells in the TME. Specifically, EVsDCC activated secretory cancer associated fibroblasts (CAFs), triggering IL-6/IL-8 signaling and sustaining CSC phenotype maintenance. Complementarily, EVsCSC promoted the activation of α-SMA+ myofibroblastic CAFs subpopulations and increased the endothelial remodeling, enhancing the invasive potential of TNBC cells in vitro and in vivo. In addition, solely the EVsCSC mediated signaling prompted the transformation of healthy lungs into receptive niches able to support metastatic growth of breast cancer cells.

Abstract
Background Lockdown measures implementation (LMI) to prevent COVID19 disease diffusion was associated to increased depression and anxiety cases. The main aim was to evaluate whether LMI affected prevalence and incidence of antidepressants (ADs) use, and ADs treatment interruption (TI) in the general population. Methods Adults (≥18 years) with at least 1 dispensing of ADs between 01/01/2019-26/09/2020 were selected from a regional Italian healthcare administrative database. Patients presenting an AD dispensing in the year preceding the first observation were considered as prevalent otherwise as incident users. We divided the studied period into 3 parts: pre-lockdown (01/01/2019-08/03/2020), lockdown (09/03/2020-14/06/2020) and post-lockdown (15/06/2020-27/09/2020). The weekly prevalence (WP) and incidence (WI) per 10,000 inhabitants were compared among periods. Incidence of TI (no dispensing refill within 30 days of the end of its validity) was computed among prevalent AD users. Results The WP (mean of 552.3 per 10,000 pre-lockdown vs 505.5 lockdown phase; relative change: -9%) and WI (5.2 vs 3.7; -29%) of ADs use decreased after LMI. During the post-lockdown phase WP (505.5 vs 495.9; -2%) decreased whereas the WI (3.7 vs 4.3; 16%) slightly increased in relation to the lockdown period, although differences were not statistically significant. Conversely, the incidence of TI increased during lockdown (344.7 vs 384.3; 12%) and post-lockdown (384.3 vs 394.2; 3%) periods, even not always statistically significant. Conclusions Our analysis showed a reduction of ADs use during the early phase of lockdown. Several factors might have impacted on the observed phenomenon (i.e, patient reluctance to start new AD treatment). Considering the mutation of the virus and the potential waves that might occur in the next months, a continuous monitoring of the impact of COVID19 on mental diseases onset and treatment adherence are suggested. Key messages In Italy, the implementation of lockdown measures was followed by a reduction in antidepressants use, even though evidences are that diagnoses of psychiatric disorders increased. Future studies should monitor if these phenomena led to an increase in adverse events potentially correlated with inappropriate treatment of depression.

Abstract
Background Effective and rapid immunologic response to vaccines is a crucial strategy for the control SARS-CoV-2 pandemic. Here, we present the results of an ongoing longitudinal observational study conducted among the healthcare workers (HCWs) of the Pineta Grande Hospital (Castel Volturno, Italy), who were administered the two-dose prime-boost mRNA vaccine BNT162b2. Methods Volunteer HCWs underwent either (i) six RT-PCR assay for qualitative detection of SARS-CoV-2 nucleic acid in nasopharyngeal/oropharyngeal swabs; (ii) or six quantitative serology testing for the research of virus-specific immunoglobulins (Ig) through chemiluminescent immunoassay with a reactivity cut-off of an Index of ≥ 1.0. The first tests were taken before the administration of the vaccine and then according to a predefined timeline. An active surveillance follow-up of SARS-CoV-2 infections was set amongst the vaccinees after the end of the study. Results Overall, among the 435 HCWs who accepted to participated in the study, 9.3% reported a previous laboratory-confirmed infection with SARS-CoV-2, though all subjects tested negative at the time of first vaccine dose. In the swab cohort, seven subjects tested positive in the first 15 days after the first vaccine dose and one about a week from the second dose. At 45- and 60-day follow-ups all vaccinees tested negative, but two positive tests were registered at the third month. In the second cohort, two weeks after the first vaccine dose anti-SARS-CoV-2 antibodies exceeded the reactivity cut-off in 82.5% the participants. At one-month follow-up, almost all (98.4%) the vaccinees had reached the maximum Index value of 10. No statistically significant associations were found between antibody response and HCWs' characteristics. Conclusions Our results showed that surveillance is a critical component of providing safe healthcare during COVID-19 pandemic, also after extended vaccination campaigns, thus enhancing the protection of patients and HCWs. Key messages All healthcare facilities should implement continuous post-vaccination surveillance programs in order to ensure patients and healthcare workers safety, and limit in-hospital transmission of SARS-CoV-2. Longer field follow-ups are indispensable to investigate immunogenicity trends and effectiveness of COVID-19 vaccines over time, and to consider booster doses, especially in high-risk population.

Abstract
Despite recent progresses in robotic rehabilitation technologies, their efficacy for post-stroke motor recovery is still limited. Such limitations might stem from the insufficient enhancement of plasticity mechanisms, crucial for functional recovery. Here, we designed a clinically relevant strategy that combines robotic rehabilitation with chemogenetic stimulation of serotonin release to boost plasticity. These two approaches acted synergistically to enhance post-stroke motor performance. Indeed, mice treated with our combined therapy showed substantial functional gains that persisted beyond the treatment period and generalized to non-trained tasks. Motor recovery was associated with a reduction in electrophysiological and neuroanatomical markers of GABAergic neurotransmission, suggesting disinhibition in perilesional areas. To unveil the translational potentialities of our approach, we specifically targeted the serotonin 1A receptor by delivering Buspirone, a clinically approved drug, in stroke mice undergoing robotic rehabilitation. Administration of Buspirone restored motor impairments similarly to what observed with chemogenetic stimulation, showing the immediate translational potential of this combined approach to significantly improve motor recovery after stroke.

Abstract
Abstract
Background
In 2017, the Global Burden of Disease Study estimated that in Europe 0.42 million deaths and 8.9 million disability-adjusted life years were attributable to air pollution. Monetizing this burden is a key step for estimating benefits of exposure reduction strategies. However, robust and synthetic estimates of direct (e.g. due to hospitalizations or medications) and indirect (e.g. due to premature mortality or loss of productivity) health-related costs of air pollution seem to be still lacking. We carried out a systematic review, aimed at identifying evidence from research in Europe.
Methods
We searched 5 electronic databases (MEDLINE, EMBASE, Cochrane Library, SCOPUS, Web Of Science) in which we applied algorithms tracing keywords such as “cost of illness”, “health care costs”, “economics” and synonyms, together with “air pollution” and synonyms. We limited our search to articles written in English and Italian, without date restriction.
Results
The initial search retrieved 2420 records. 200 were classified as relevant, and 38 fulfilled inclusion criteria. Most of them (68%) were published after 2010. 26% were multi-country studies, while the remaining focused on a single country or city. Investigated pollutants were usually particulate matter (79% of the studies) and nitrogen oxides (37%). The approaches to the economic analysis were heterogeneous: estimates could include direct and/or indirect costs. Among the studies, the most comprehensive one (12 countries) estimated that complying with WHO guidelines would avert €31 billion yearly, of which €19 million due to hospitalizations.
Conclusions
Over the last decade, progress has been made in evaluating the economic burden of air pollution. However, estimates based on indirect costs are affected by high levels of uncertainty, while those based on direct costs are more robust and should be further investigated, since they are crucial information for healthcare policy makers.
Key messages
Air pollution poses a high economic burden on European countries, mainly due to social costs. More attention should be devoted to estimating direct healthcare costs of air pollution, in order to properly inform policy makers about the impact on healthcare systems.

Abstract
Abstract
Background
Cardiovascular diseases (CVDs) are still the leading cause of mortality, morbidity and disability in Europe. Consequently, an exhaustive estimation of CVDs burden and cardiovascular risk factors impact is crucial for healthcare planning and resource allocation. In Italy, data on CVDs burden are sparse. This study aims to assess the global Italian CVDs burden and to analyze time changes from 1990 to 2017 within the country and in comparison to other European states.
Methods
We used data from the 2017 Global Burden of Diseases (GBD) study to estimate CVDs prevalence, mortality and disability-adjusted life-years (DALYs) in Italy from 1990 to 2017. We also analyzed burden attributable to CVDs-related risk factors. Finally, Italian estimations were compared to those of the other 28 European Union countries.
Results
CVDs were still the first cause of death (34.8% of total mortality) in Italy in 2017. A significant decrease in CVDs burden was observed since 1990: age-standardized prevalence (-12.7%), mortality rate (-53.75%), and DALYs rate (-55.54%) all decreased. Similar patterns were observed also in the majority of European countries. Despite these trends, all-ages CVDs prevalent cases increased from 5.75 million to 7.49 million. More than 80% of CVDs burden could be attributed to known modifiable risk factors such as high systolic blood pressure, dietary risks, high LDL cholesterol, and impaired kidney function.
Conclusions
Data showed a decline in cardiovascular mortality and DALYs, which reflects the success in terms of reducing disability, premature death and early incidence of CVDs. However, the burden of CVDs is still high, as population aging and the increased prevalent cases require more access to care and generate more years lived with disability, which in turn leads to higher costs for the National Health Service and society. More efficient prevention strategies at community and individual level are needed.
Key messages
Despite decreasing trends in CVDs mortality and DALYs, the burden of CVDs is still high in Italy. A joined approach of the National Health System stakeholders is needed to keep reducing the CVDs burden.

Abstract
Abstract
Background
Previous attempts estimated the impact of infectious agents on cancer incidence in Italy, but the burden of carcinogenic infections on cancer mortality remains unknown. Therefore, we aimed to conduct a preliminary analysis in order to estimate this burden at country level.
Methods
We applied the global, regional, or national population attributable fractions for Helicobacter pylori, hepatitis B virus (HBV), hepatitis C virus (HCV), high-risk human papillomavirus (HPV) types, Epstein-Barr virus (EBV), human herpesvirus type 8 (HHV-8), and human T-cell lymphotropic virus type 1 (HTLV-1) - all microorganisms ranked as group 1 carcinogenic agents in human beings by the International Agency for Research on Cancer - to 2015 cancer-related deaths recorded according to the 10th International Classification of Diseases coding system in Italy.
Results
We estimated a total of 14,120 deaths attributable to carcinogenic infections, being 8.3% of the total of cancer-related deaths (n = 170,339). 58.8% of those occurred in men. H. pylori, HCV, HBC, and HPV accounted for 96.4% of the whole mortality burden attributable to carcinogenic infections in both sexes. H. pylori was responsible for 8,116 (57.5%) deaths due to gastric carcinoma (non-cardia and non-Hodgkin lymphoma). Hepatitis-related liver cancer accounted for a total 4,372 deaths: 3,812 due to HCV infection and 560 to HBV. Cancers related to HPV infection represented the third most frequent cause of deaths due to carcinogenic infections in women.
Conclusions
We estimated that one out of 12 cancer deaths in Italy was attributable to an infection sustained by carcinogenic agents. Such mortality burden is potentially avoidable, given that these infections are both potentially preventable and treatable. Thus, these estimates provide actionable metric of the burden for the implementation of specific public health measures. Further analyses will provide more accurate estimates of this disease burden.
Key messages
In Italy, one out of 12 cancer-related deaths is attributable to infections sustained by preventable or treatable carcinogenic agents. These estimates provide metric of carcinogenic infections for the implementation of specific public health measures to avert the related mortality burden.

Abstract
OBJECTIVE Translational studies on motor control and neurological disorders require detailed monitoring of sensorimotor components of natural limb movements in relevant animal models. However, available experimental tools do not provide a sufficiently rich repertoire of behavioral signals. Here, we developed a robotic platform that enables the monitoring of kinematics, interaction forces, and neurophysiological signals during user-defined upper limb tasks for monkeys. APPROACH We configured the platform to position instrumented objects in a three-dimensional workspace and provide an interactive dynamic force-field. MAIN RESULTS We show the relevance of our platform for fundamental and translational studies with three example applications. First, we study the kinematics of natural grasp in response to variable interaction forces. We then show simultaneous and independent encoding of kinematic and forces in single unit intra-cortical recordings from sensorimotor cortical areas. Lastly, we demonstrate the relevance of our platform to develop clinically relevant brain computer interfaces in a kinematically unconstrained motor task. SIGNIFICANCE Our versatile control structure does not depend on the specific robotic arm used and allows for the design and implementation of a variety of tasks that can support both fundamental and translational studies of motor control.

Abstract
We show that nonlinear continuum elasticity can be effective in modeling plastic flows in crystals if it is viewed as a Landau theory with an infinite number of equivalent energy wells whose configuration is dictated by the symmetry group GL(2,Z). Quasistatic loading can be then handled by athermal dynamics, while lattice-based discretization can play the role of regularization. As a proof of principle, we study dislocation nucleation in a homogeneously sheared 2D crystal and show that the global tensorial invariance of the elastic energy foments the development of complexity in the configuration of collectively nucleating defects. A crucial role in this process is played by the unstable higher symmetry crystallographic phases, typically thought to be unrelated to plastic flow.

Abstract
Abstract
Background
The accuracy of currently available bleeding scores in patients on treatment with direct oral anticoagulants (DOACs) for venous thromboembolism (VTE) is undefined.
Purpose
In a prospective cohort of patients with VTE treated with DOACs, we evaluated the accuracy of the ATRIA, HAS-BLED, Kuijer, ORBIT, RIETE and VTE-BLEED risk scores in predicting major bleeding (according to ISTH definition).
Methods
The accuracy of different scores to correctly classify subjects into a defined risk category was assessed by the c-statistic.
Results
Overall, 1141 patients were evaluated and 1034 included in the study. The index event was pulmonary embolism in 509 patients (49.2%) and proximal deep vein thrombosis in the remaining patients (50.8%). During the 12-month study period, 26 major bleedings occurred in 25 patients (2.8% patient-year): 14 major bleedings occurred in the first 6 months of treatment and 12 from 6 to 12 months in the 654 patients remained on treatment.
In the 12-month study period, the VTE-BLEED score showed the best predictive value for bleeding complications (c-statistics 0.674, 95% CI 0.593–0.755). The lowest incidence of major bleeding (0.3%) was observed in the low risk category of VTE-BLEED which includes 38% of patients. The highest incidence of major bleeding (7.1%) was observed in the high-risk category of ORBIT which includes 10.9% of patients.
Conclusions
The VTE-BLEED score had the best accuracy in predicting major bleeding during treatment with DOACs for VTE. Whether the VTE-BLEED score can be used for decision making on anticoagulation should be tested in a management study.

Abstract
BACKGROUND This study is part of a national plan of epidemiological surveillance of malignant mesothelioma (MM) mortality in Italy. The paper shows the results of malignant peritoneal mesothelioma (MPeM) mortality study in Italian Regions and municipalities. METHODS National Bureau of Statistics data for MPeM municipal mortality (ICD-10, Code C45.1) were analyzed in the time-window 2003-2014: mortality standardized rates (reference Italian population, census 2011), temporal trends of the annual national rates, Standardized Mortality Ratios and a municipal clustering analysis were performed. RESULTS 747 deaths for MPeM were recorded (0.10/100,000): 464 in men (0.14/100,000) and in 283 women (0.07/100,000). No significant MPeM mortality temporal trend was found. Seventeen municipalities showed excesses of mortality for MPeM in at least one gender and/or overall population. Four clusters in male population, and one in women were identified. CONCLUSIONS The study identifies some areas where remediation activities and/or health care actions may be warranted.

Abstract
BACKGROUND At present cervical cancer represents the second most common cancer in women worldwide and it reaches a global mortality rate of 52%. Only the early detection and the adequate treatment of pre-neoplastic lesions and early-stage cervical cancer decrease the mortality rate for this type of cancer. Cervical carcinoma screening, as a method of second prevention, is currently feasible through molecular research of high-risk HPV genotypes and in lots of organized screening programs the Pap-test is performed only in women with positive HPV-test. Currently, there are various diagnostic platforms detecting and molecular genotyping HPV, which are based on different procedures, determining uneven viral genotypes panels and using diverse type of vials to collect and store the samples. Previous studies have pointed out that DNA-HPV test can be negative in pre-neoplastic lesions, even of high grade, or in presence of cervical cancer. Therefore, it's important to assess the risk of false negative diagnoses using DNA-HPV molecular test, because in this circumstance women do not undergo immediately Pap-test, but they are submitted to second round screening with DNA-HPV test after 5 years: this protocol could increase the incidence of "interval cancers". The present study aims at comparing the results of HPV detection and genotyping on liquid based cervical cytology, using some of the most relevant diagnostic platforms in commerce. METHODS The study is based on a group of patients which went to their private gynecologist in a contest of opportunistic screening. The vial used in the examined population has been EASYPREP® preservative solution (YD Diagnostics CORP-Republic of Korea); liquid-based cervical cytology sampling has been done using a single device (plastic brush), allowing to collect simultaneously cytological material from exocervix and endocervix (Rovers® Cervex-Brush®). The diagnostic platforms employed have been the following: A) Digene HC2 HPV DNA Test, on RCS System (QIAGEN); B) BD Onclarity™ HPV test, on automate platform BD Viper™ LT (Becton Dickinson); C) Xpert® HPV, on GeneXpert® Infinity Systems platform (Cepheid). Every platform researched high-risk HPV genotypes panels (hr-HPV). Part of the clinical records has also been analyzed through PCR and genes L1 and E6/E7 complete sequencing, in order to further typing the viral population. RESULTS We have examined 1284 samples of women aged 16 to 73 years: 1125 have been tested using HC2 procedure, 272 samples with Onclarity method, 159 with Xpert® method and 55 samples have been analyzed using PCR and sequencing of gene L1 and gene E6/E7. HPV-DNA was detected with Onclarity method in 15,07%, with Xpert® method in 13,83% and using HC2 procedure in 12,27% of samples. The comparison between the three molecular methods revealed diagnostic discrepancies in 3,14% of our records between Onclarity test and Xpert® method and in 2,20% (6/272) between HC2 test and Onclarity test. Globally, in 431 tests, compared using different diagnostic platforms, discrepant diagnoses, referring to hr-HPV presence or to detected genotype, have been observed 11 times (2,55%). Genotype 16 appeared the most expressed in the positive samples (20,99%), whereas genotype 18 resulted the less expressed in the examined population (4,94%). DISCUSSION The present study highlights the following: 1) Positive results' percentage for high-risk HPV-DNA genotypes, deriving from the three diagnostic platforms used and with the same vial to collect and store samples, does not significantly vary on the basis of the type of equipment and it is congruent with the Italian percentage already detected during organized screening programs. 2) Even the molecular diagnostic approach could give false negative results, preventing the detection in the screened population of cervical HPV-related lesions and theoretically endangering women to develop "interval cancer". 3) In the population examined, genotype 16 has been the most expressed, whereas genotype 18 was among the less frequently detected. Other genotypes often noticed have been: 56-59-66 (Onclarity P3 group), 31, 51 and 35-39-68 (Onclarity P2 group). This remark emphasizes the importance of HPV infection and genotypes distribution's continuous monitoring, considering that HPV-vaccines planned in Italy in the "National vaccination prevention program 2017-2019" are not specific for the majority of these genotypes. 4) The necessity to improve the screening program to identify cervical carcinomas and pre-neoplastic cervical lesions is remarked by the detection during HPV-test of possible coinfection (present at least in 8,76% of our records). In fact, the risk of development of cervical cancer might be associated with type-specific interactions between genotypes in multiple infections and, in addition, other genotypes, not targeted by quadrivalent HPV-vaccine, can increase the risk of cervical carcinoma. 5) As there's a different combination of HPV-genotypes in diagnostic categories used by the HPV screening platforms, it's important that anyone who is in charge of this diagnostic analysis promotes among clinicians the adequate rendition of the laboratory's data in the patient records, reporting both the diagnostic result and the method through which it has been obtained.

Abstract
Background: Radiotherapy is one of the primary therapies for
localized prostatic carcinoma. Therefore, there is an emerging need to sensitize
prostatic cancer cells to chemotherapy/radiotherapy. Modified citrus pectin
(MCP) is an effective inhibitor of galectin-3 (Gal-3), which is correlated with
tumor progression, proliferation, angiogenesis, and apoptosis.
Purpose: This study was directed to evaluate the efficacy of
combining ionizing radiation (IR) with MCP on PCa cells. Study
Design: Effects of treatments on PCa cells survival were evaluated
using XTT assay, flow cytometry, and clonogenic survival assay. Expression of
selected proteins was estimated using western blotting. Cell motility,
migration, and invasion were determined. Contribution of reactive oxygen species
production to treatment effects on cell viability was tested.
Results: Radiotherapy combined with MCP reduced viability and
enhanced radiosensitivity associated with a decrease in Gal-3, cleavage of the
precursor of caspase-3, increased expression of the pro-apoptotic protein Bax,
and downregulation of DNA repair pathways, poly-ADP-ribose polymerase, and
proliferating cell nuclear antigen. MCP significantly reduced the invasive and
migratory potential of PCa cells. Combining sodium pyruvate with MCP and IR
mitigated the effect on cell viability. Conclusion: Our findings
demonstrated that MCP sensitized PCa cells to IR by downregulating
anti-apoptotic Gal-3, modulating DNA repair pathways, and increasing ROS
production. For the first time the correlation between MCP, radiotherapy, and
Gal-3 for prostatic cancer treatment was found. In addition, MCP reduced the
metastatic properties of PCa cells. These findings provide MCP as a
radiosensitizing agent to enhance IR cytotoxicity, overcome radioresistance, and
reduce clinical IR dose.

Abstract
Glioblastoma multiforme (GBM) is the most common and most aggressive subtype of malignant gliomas. The current standard of care for newly diagnosed GBM patients involves maximal surgical debulking, followed by radiation therapy and temozolomide chemotherapy. Despite the advances in GBM therapy, its outcome remains poor with a median survival of less than two years. This poor outcome is partly due to the ability of GBM tumors to acquire adaptive resistance to therapy and in particular to radiation. One of the mechanisms contributing to GBM tumor progression and resistance is an aberrant activation of NF-ĸB, a family of inducible transcription factors that play a pivotal role in regulation of many immune, inflammatory and carcinogenic responses. Acetyl-11-keto-β-boswellic acid (AKBA) is a pentacyclic terpenoid extracted from the gum Ayurvedic therapeutic plant Boswellia serrata. AKBA is anti-inflammatory agent that exhibits potent cytotoxic activities against various types of tumors including GBM. One of the mechanisms underlying AKBA anti-tumor activity is its ability to modulate the NF-ĸB signaling pathway. The present study investigated in vitro and in vivo the effect of combining AKBA with ionizing radiation in the treatment of GBM and assessed AKBA anti-tumor activity and radio-enhancing potential. The effect of AKBA and/or radiation on the survival of cultured glioblastoma cancer cells was evaluated by XTT assay. The mode of interaction of treatments tested was calculated using CalcuSyn software. Inducing of apoptosis following AKBA treatment was evaluated using flow cytometry. The effect of combined treatment on the expression of PARP protein was analysed by Western blot assay. Ectopic (subcutaneous) GBM model in nude mice was used for the evaluation of the effect of combined treatment on tumor growth. Immunohistochemical analysis of formalin-fixed paraffin-embedded tumor sections was used to assess treatment-related changes in Ki-67, CD31, p53, Bcl-2 and NF-ĸB-inhibitor IĸB-α. AKBA treatment was found to inhibit the survival of all four tested cell lines in a dose dependent manner. The combined treatment resulted in a more significant inhibitory effect compared to the effect of treatment with radiation alone. A synergistic effect was detected in some of the tested cell lines. Flow cytometric analysis with Annexin V-FITC/PI double staining of AKBA treated cells indicated induction of apoptosis. AKBA apoptotic activity was also confirmed by PARP cleavage detected by Western blot analysis. The combined treatment suppressed tumor growth in vivo compared to no treatment and each treatment alone. Immunohistochemical analysis showed anti-angiogenic and anti-proliferative activity of AKBA in vivo. It also demonstrated a decrease in p53 nuclear staining and in Bcl-2 staining and an increase in IĸB-α staining following AKBA treatment both alone and in combination with radiotherapy. In this study, we demonstrated that AKBA exerts potent anti-proliferative and apoptotic activity, and significantly inhibits both the survival of glioblastoma cells in vitro and the growth of tumors generated by these cells. Combination of AKBA with radiotherapy was found to inhibit factors which involved in cell death regulation, tumor progression and radioresistence, therefore it may serve as a novel approach for GBM patients.

Abstract
Superfluidity in coupled electron-hole sheets of bilayer graphene is predicted here to be multicomponent because of the conduction and valence bands. We investigate the superfluid crossover properties as functions of the tunable carrier densities and the tunable energy band gap E_{g}. For small band gaps there is a significant boost in the two superfluid gaps, but the interaction-driven excitations from the valence to the conduction band can weaken the superfluidity, even blocking the system from entering the Bose-Einstein condensate (BEC) regime at low densities. At a given larger density, a band gap E_{g}∼80-120 meV can carry the system into the strong-pairing multiband BCS-BEC crossover regime, the optimal range for realization of high-T_{c} superfluidity.

Abstract
We consider a partial differential inclusion problem which models stress-free martensitic inclusions in an austenitic matrix, based on the standard geometrically nonlinear elasticity theory. We show that for specific parameter choices there exist piecewise affine continuous solutions for the square-to-oblique and the hexagonal-to-oblique phase transitions. This suggests that for specific crystallographic parameters the hysteresis of the phase transformation will be particularly small.

Abstract
Abstract
Radio-resistance is a major cause of decreasing the efficiency of radiotherapy for prostate cancer. Modified citrus pectin (MCP) has been previously shown to demonstrate anti-proliferative and anti-metastatic activity in prostate cancer cells. However, its combination with radiation has not been evaluated. The aim of the present study was to investigate whether MCP radiosensitized prostate cancer cell lines and to unravel its underlying mechanism(s). XTT cell proliferation and clonogenic assays were used to assess MCP effect alone and in combination with radiation on viability of prostate cancer cell lines (DU-145, PC-3 and Cl-1). Calcusyn software analysis was used to determine the mode of interaction between the treatments tested. Flow cytometry analysis with propidium iodide staining, annexin-V-FITC and 7-aminoactinomycin D (7-AAD) double staining were used to evaluate effect on cell cycle, apoptosis and necrosis. Standard Transwell Assay with and without Matrigel was used to assess effect of MCP on invasiveness of cells. The effect of MCP and radiation on reactive oxygen species (ROS) production, and expression of galectin-3, PARP, caspase-3, caspase-9, Bak, Bax, and Bcl-2 and NF-κB pathways in treated cells are currently being investigated, and will be included in the presentation. Treatment of DU-145, PC-3 and Cl-1 prostate cancer cells with MCP induced a dose dependent decrease in cell viability tested by XTT assay (IC50 values were 1.07, 1.48, 1.29 mg/ml respectively). These cells demonstrated similar radio-sensitivity. The effect of the combined treatment were either synergistic (Combined index∼0.7, DU-145 and Cl-1 cells) at high dose (2 mg/ml) of MCP or additive (Combined index 1.1-0.9, PC-3 cells). Flow cytometric analysis showed that neither MCP nor radiation either alone or combined resulted in significant changes in cell cycle distribution. Double staining of DU-145 cells with annexin-V-FITC and 7-AAD revealed effect of combined treatment on apoptosis and necrosis. Treatment of cells with 2 mg/ml MCP reduced 20% of migrating cells and 40% of invasive cells. The effects of MCP and radiation on ROS production, pro-apoptotic and NF-κB pathways in treated cells are currently being investigated. These results suggest that MCP is a radiosensitizer in prostate cancer cells. Its mechanism of action is being investigated, and will be included in this presentation.

Abstract
Components of the death receptor-mediated pathways like caspase-8 have been identified in complexes at intracellular membranes to spatially restrict the processing of local targets. In this study, we report that the long isoform of the cellular FLICE-inhibitory protein (c-FLIP(L)), a well-known inhibitor of the extrinsic cell death initiator caspase-8, localizes at the endoplasmic reticulum (ER) and mitochondria-associated membranes (MAMs). ER morphology was disrupted and ER Ca(2+)-release as well as ER-mitochondria tethering was decreased in c-FLIP(-/-) mouse embryonic fibroblasts (MEFs). Mechanistically, c-FLIP ablation resulted in enhanced basal caspase-8 activation and in caspase-mediated processing of the ER-shaping protein reticulon-4 (RTN4) that was corrected by re-introduction of c-FLIP(L) and caspase inhibition, resulting in the recovery of a normal ER morphology and ER-mitochondria juxtaposition. Thus, the caspase-8 inhibitor c-FLIP(L) emerges as a component of the MAMs signaling platforms, where caspases appear to regulate ER morphology and ER-mitochondria crosstalk by impinging on ER-shaping proteins like the RTN4.

Abstract
Ischemia/reperfusion (I/R) injury is a major determinant of graft survival in kidney transplantation. Survivin, an inhibitor of apoptosis that participates in the control of mitosis and cell cycle progression, has been implicated in renal protection and repair after I/R injury; however, no study has been performed in the transplant setting. We investigated the role of survivin in modulating posttransplant I/R injury in syngeneic and allogeneic kidney grafts, and studied whether protection from I/R injury impacted on the recipient immune system, on chronic allograft nephropathy and rejection. We used genetically engineered mice with survivin haploinsufficiency and WT mice in which survivin over-expression was induced by gene-delivery. Survivin haploinsufficiency in syngeneic grafts was associated with exuberant I/R tissue injury, which triggered inflammation eventually resulting in graft loss. Conversely, survivin over-expression in the grafts minimized I/R injury and dysfunction in syngeneic grafts and in a clinically relevant fully MHC-mismatched allogeneic combination. In the latter, survivin over-expression translated into limited anti-donor adaptive immune response and less long-term allograft injury with protection from renal parenchymal damage. Our data support survivin over-expression in the graft as a novel target for protocols aimed at limiting tissue damage at the time of transplant ultimately modulating the recipient immune system.

Abstract
INTRODUCTION According to IARC, shift work resulting in disruption of circadian rhythm is a probable human carcinogen (Group 2A). METHODS We examined the scientific literature on the carcinogenic risk among shift workers for risk assessment purposes. RESULTS Clock genes polymorphisms might contribute with suppression of melatonin synthesis, immuno-suppression from sleep deprivation, individual habits associated with shift work, and low vitamin D levels, in increasing risk of breast cancer, prostate cancer and lymphoma among shift workers. CONCLUSION Although the epidemiological evidence seems scanty, the hypothesis that shift work-related sleep deprivation would contribute to increasing cancer risk seems based on solid ground.

Abstract
This study assessed the immunisation status against hepatitis B in healthcare students and residents, before their hospital internship, as suggested by the "National Immunization Prevention Plan 2012-2014". The concentration of antibodies against hepatitis B was measured in 2,491 subjects (70.90% women), born between 1980 and 1993 and visited between January 1st 2000 and July 15th 2012. Personal and serologic data were collected for each subjects. Individuals with antibody less than 10 mIU/mL (327, 13.3%) were given a booster dose and re-tested 2 months later. The multivariate logistic regression evidenced that immunization is influenced by the gender, the age at first vaccination, the time elapsed between first vaccination and antibody measurement. This study confirms the importance of measuring the concentration of antibodies against hepatitis B among healthcare students, even if they have previously been vaccinated, according to the "National Immunization Prevention Plan 2012-2014".

Abstract
SENTIERI Project is the first comprehensive study of the health impact of residence in Italian polluted sites (IPSs). The present Chapter examines the main validity aspects of the present mortality investigation and the evaluation of causality of the observed associations; in addition, some recommendations for public health intervention and research priorities in epidemiological studies on environment and health are given. Exposure ascertainment is a key aspect when an ecological study design is adopted in environmental epidemiology, therefore any exposure potentially affecting the population at study should be described in detail. This is here discussed. SENTIERI is an ecological study, based on a priori hypotheses, in which each IPS's types of exposure were described with specific attention to human exposure. Though, when commenting the results, the problem of concurrent air pollution exposure and/or industrial activities implying occupational risk, if present in the IPSs, was taken into account. Socioeconomic status is a determinant of health and disease, therefore in SENTIERI the Standardized Mortality Ratios were computed both crude and adjusted for an ad hoc deprivation index. About 60% versus an expected 40% of IPSs residents are in the two most deprived quintiles of the index. This hints to a possible problem of environmental justice that should be taken into account when planning remediation intervention. The mortality results here presented are a first step in the epidemiological IPSs' characterization, and some developments have been made or planned. Firstly, a mortality analysis was performed combining mortality data in IPSs presenting similar pollution, i.e. asbestos, or industrial hazardous wastes or dumping sites; secondly, the mortality analysis will be extended beyond 2002, namely the year when ICD X started to be in use in Italy. In addition, disease prevalence will be investigated using hospital discharge records; cancer incidence and congenital anomalies incidence will be studied in IPSs in which a Cancer Register or a Congenital Anomalies Register are active. The above described activities will lead to a more valid estimate of the disease burden of IPSs residents, and allow to identify priorities of remediation activities. The method adopted in SENTIERI, specifically the ecological design and the use of mortality data at municipal level, in general does not grant the evaluation of the causal association between environmental exposure and adverse health effects. However, it allows etiological observations that make unacceptable the delay of remediation intervention.

Abstract
The methods of mortality analysis in Italian polluted sites (IPS) are described. The study concerned 44 IPSs; each one included one or more municipalities. Mortality at municipality level was studied in the period 1995-2002, using the following indicators: crude rate, standardized rate, standardized mortality ratio (SMR), and SMR adjusted for an ad hoc deprivation index. Regional populations were used as reference for indirect standardization. The deprivation index was constructed using the 2001 national census variables representing the following socioeconomic domains: education, unemployment, dwelling ownership, overcrowding. Mortality indicators were computed for 63 single or grouped causes. The results for all the 63 analysed causes of death are available for each IPS, and in this Chapter the results for each IPS for causes selected on the basis of a priori evidence of risk from local sources of environmental pollution are presented. The procedures and results of the evidence evaluation have been published in the 2010 Supplement of Epidemiology & Prevention devoted to SENTIERI.

Abstract
SENTIERI Project (Mortality study of residents in Italian polluted sites) studied mortality of residents in the sites of national interest for environmental remediation (Italian polluted sites--IPSs). IPSs are in proximity of either active or dismissed industrial areas, near dumping sites of industrial and hazardous waste or incinerators. SENTIERI Project described and evaluated the mortality of the populations residing in IPSs and it specifically focused on causes of death for which environmental exposure is suspected or ascertained to play an etiologic role. The epidemiological evidence of the causal association was classified a priori into one of these three categories: Sufficient (S), Limited (L) and Inadequate (I). The study results will allow the priorities setting in remediation intervention, so as to prevent adverse health effects from environmental exposure. At the time of 2001 Census, about 10%of Italian population resided in the 44 IPSs included in SENTIERI; the mortality analysis was carried out for the years 1995-2002 for 63 causes of death. The study results for the 44 IPSs are here commented and read on the basis the a priori evaluation of the epidemiological evidence in terms of strength of the causal association, and taking into account the limits of a geographic study design and its implied complexities. The procedures and results of the evidence evaluation have been presented in a 2010 Supplement of Epidemiology & Prevention devoted to SENTIERI.

Abstract
In Italy, complete municipality-level data on specific-cause mortality have been available at central level since 1980; Italy's National Institute of Statistics (Istat) collects data from all municipalities using two sources: i) the Office of Vital Statistics; and ii) the Civil Status Office. The Office of Vital Statistics records data on events such as births, deaths and migration for the population with official residence in the municipality, with the aim of describing the resident population's structure and composition. The Civil Status Office records data on the demographic dynamics (not only marital status but also causes of death); the data refer to the population living in the municipality, independently of official residence. Changes in the status of a municipality (e.g., the creation of a new municipality or the unification of diverse municipalities) are often not recorded simultaneously by these two offices, so that the data do not correspond.

Abstract
A laboratory and on-the-field study was conducted to compare Floor-Based (FB) and Ceiling-Based (CB) patients transfer devices. Pushing and pulling forces were measured by means of computer assisted dynamometer. EMG signals were measured. Standardized patient transfers were setup in the room (bed-chair-door-return). FB devices showed pushing and pulling forces higher than CB ones. CB paths were the smoothest and EMG data related to upper arms and trunk muscles showed stable lower loads for CB. The study suggests that CB patient transfer devices reduced the load. CBs seem the best tools for patient handling.
