Abstract
BACKGROUND AND AIMS International guidelines advise improving esophagogastroduodenoscopy (EGD) quality in Western countries, where gastric cancer is still diagnosed in advanced stages. This nationwide study investigated some indicators for the quality of EGD performed in endoscopic centers in Italy. METHODS Clinical, endoscopic, and procedural data of consecutive EGDs performed in one month in the participating centers were reviewed and collected in a specific database. Some quality indicators before and during endoscopic procedures were evaluated. RESULTS A total of 3,219 EGDs performed by 172 endoscopists in 28 centers were reviewed. Data found that some relevant information (family history for GI cancer, smoking habit, use of proton pump inhibitors) were not collected before endoscopy in 58.5-80.7% of patients. Pre-endoscopic preparation for gastric cleaning was routinely performed in only 2 (7.1%) centers. Regarding the procedure, sedation was not performed in 17.6% of patients, and virtual chromoendoscopy was frequently (>75%) used in only one (3.6%) center. An adequate sampling of the gastric mucosa (i.e., antral and gastric body specimens) was heterogeneously performed, and it was routinely performed only by 23% of endoscopists, and in 14.3% centers. CONCLUSIONS Our analysis showed that the quality of EGD performed in clinical practice in Italy deserves to be urgently improved in different aspects.

Abstract
BACKGROUND Individuals with Down syndrome (DS) appear to perform at a level that is commensurate with developmental expectations on simple tasks of selective attention. In this study, we examine how their selective attention is impacted by target changes that unfold over both time and space. This increased complexity reflects an attempt at greater ecological validity in an experimental task, as a steppingstone for better understanding attention among persons with DS in real-world environments. METHODS A modified flanker task was used to assess visual temporal and spatial filtering among persons with DS (n = 14) and typically developing individuals (n = 14) matched on non-verbal mental age (mental age = 8.5 years). Experimental conditions included varying the stimulus onset asynchronies between the onset of the target and flankers, the distances between the target and flankers, and the similarity of the target and flankers. RESULTS Both the participants with DS and the typically developing participants showed slower reaction times and lower accuracy rates when the flankers appeared closer in time and/or space to the target. CONCLUSION No group differences were found on a broad level, but the findings suggest that dynamic stimuli may be processed differently by those with DS. Implications of the findings are discussed in relation to the developmental approach to intellectual disability originally articulated by Ed Zigler.

Abstract
The work of Ed Zigler spans decades of research all singularly dedicated to using science to improve the lives of children facing different challenges. The focus of this article is on one of Zigler's numerous lines of work: advocating for the practice of mental age (MA) matching in empirical research, wherein groups of individuals are matched on the basis of developmental level, rather than chronological age. While MA matching practices represented a paradigm shift that provided the seeds from which the developmental approach to developmental disability sprouted, it is not without its own limits. Here, we examine and test the underlying assumption of linearity inherent in MA matching using three commonly used IQ measures. Results provide practical constraints of using MA matching, a solution which we hope refines future clinical and empirical practices, furthering Zigler's legacy of continued commitment to compassionate, meaningful, and rigorous science in the service of children.

Abstract
Individuals with ASD often display externalizing behaviors, which have been associated with lower quality of life in adulthood. Social difficulties have been hypothesized to underlie externalizing problems among individuals with ASD (Klin and Volkmar in Asperger Syndrome, 340-366, 2000), but this has never been tested empirically. We examined whether socialization abilities predicted externalizing problems assessed by parent report in a group of 29 individuals with ASD (age range 7-16 years) and 29 TD individuals matched for IQ, age, and gender. Socialization scores accounted for 50% of the variance in externalizing behaviors among individuals with ASD, but not in TD children. These findings have implications for intervention, and suggest that targeting social difficulties might provide a better means to addressing externalizing problems.

Abstract
Platinum(ii)-based molecules are the most commonly used anticancer drugs in the chemotherapeutic treatment of tumours but possess serious side effects and some cancer types exhibit resistance with respect to these compounds (e.g. cisplatin). For these reasons, the research of new compounds that can bypass this limitation is in continuous development. Recently, mixed Pt(ii)-As(iii) systems have been synthesized and tested as potential anticancer agents. The mechanism of action of these kinds of drugs is unclear. Since in other platinum(ii) containing drugs, hydrolysis plays an important role in the activation of the compound before it reaches DNA, we have explored the aquation process using density functional theory (DFT), focusing our attention on the arsenoplatin complex, [Pt(μ-NHC(CH3)O)2ClAs(OH)2]. As DNA is believed to be the cellular target for Pt anticancer drugs, the metalation mechanism of DNA purine bases has been also investigated. Also for this new drug it appears that guanine is the preferred site with respect to adenine as with other platinum-containing compounds. A comparison with cisplatin is performed in order to highlight the contribution of arsenic in the anticancer activity of this new proposed anticancer agent.

Abstract
In this paper, we report a theoretical investigation of the reduction reaction mechanism of Me3NO using molybdenum containing systems that are functional and structural analogues of trimethylamine N-oxide reductase mononuclear molybdenum enzyme. The reactivity of the monooxomolybdenum(IV) benzenedithiolato complex and its derivatives to carbamoyl (t-BuNHCO) and acylamino (t-BuCONH) substituents on the benzene rings in both cis and trans arrangements was explored. The calculated energy profiles describing the steps of two mechanisms of attack considered viable (named cis- and trans-attack) by the Me3NO substrate at cis and trans positions with respect to the oxo ligand show that the attack on cis is energetically more favourable than the attack on trans. Along the pathway for the cis-attack the first step of the reaction, that is rate-determining for all the studied compounds, is the approach of the substrate to the Mo centre in cis to the oxo ligand that causes a distortion of the initial square-pyramidal geometry of the complex. The reaction steps involved in the trans position attack were also explored. Calculations confirm that, as previously suggested, the introduction of ligands able to form intramolecular NH···S hydrogen bonds accelerates the reduction of the Me3NO substrate and contributes to the tuning of the reactivity of molybdoenzyme models.

Abstract
In order to give insights into the working mechanism of the novel characterized enzyme carbonyl sulphide hydrolase (COSase), which efficiently converts COS into H2S and CO2, we have performed a detailed theoretical investigation using the framework of density functional theory (using B3LYP and M06 exchange-correlation functionals) by the cluster model approach. In the final part of the reaction the metal ion is unable to form a pentacoordinated species. The B3LYP-D3 and M06 potential energy surfaces have a very similar shape. The elucidation of the catalytic reduction of COS is important in view of its role in environmental chemistry.

Abstract
Nitrous oxide activation by CO in the presence of platinum and rhodium monocations was elucidated by density functional methods for ground and first excited states. Platinum and rhodium cations fulfill the thermodynamic request for the oxygen-atom transport that allows the catalytic cycle to be completed, but actually, just the first one meaningfully improves the kinetics of the process. For both catalysts, the reaction pathways show the only activation barrier in correspondence of nitrogen release and monoxide cation formation. The kinetic analysis of the potential energy profile, in agreement with ICP/SIFT MS experimental data, indicates that platinum performs more in the reduction, while the whole process is not sufficiently fast in the case of rhodium ionic catalyst.

Abstract
BACKGROUND Although risk for psychosis in velocardiofacial (22q11.2 deletion) syndrome (VCFS) is well established, the cognitive and familial factors that moderate that risk are poorly understood. METHOD A total of 75 youth with VCFS were assessed at three time points, at 3-year intervals. Time 1 (T1) psychiatric risk was assessed with the Behavior Assessment System for Children (BASC). Data reduction of BASC scores yielded avoidance-anxiety and dysregulation factors. Time 2 (T2) neuropsychological and family function and time 3 (T3) prodromal/overt psychosis were assessed. Poisson regression models tested associations between T3 positive prodromal symptoms/overt psychosis and T1 psychiatric risk, T2 cognitive and familial factors, and their interactions. RESULTS T1 avoidance-anxiety ratings predicted T3 prodromal/overt psychosis. T2 verbal learning scores moderated this association, such that individuals with low avoidance-anxiety scores and stronger verbal learning skills were the least likely to demonstrate prodromal/overt psychosis at T3. Low scores on a T2 visual vigilance task also predicted T3 prodromal/overt psychosis, independently of the effect of T1 avoidance-anxiety scores. T1 dysregulation scores did not predict T3 prodromal/overt psychosis in a linear manner. Instead, the association between dysregulation and prodromal/overt psychosis was amplified by T2 levels of family organization, such that individuals with low dysregulation scores and low family organization scores were the most likely to exhibit T3 prodromal/overt psychosis. CONCLUSIONS Significant moderators of psychiatric risk in VCFS include verbal learning skills as well as levels of family organization, carrying implications for early identification and preventative treatment of youth with VCFS at highest risk for psychosis.

Abstract
INTRODUCTION Estetrol (E4), a naturally occurring estrogen only produced by the human fetal liver, is being evaluated in human studies for potential use in contraception and menopausal care. The present study was designed to profile E4 in the central nervous system, to assess the in vivo effects of E4 administration on allopregnanolone (AP) synthesis in specific brain structures and to evaluate whether E4 has synergic or antagonistic effects on estradiol-mediated AP synthesis. MATERIAL AND METHODS Intact female adult rats received different doses of E4, and ovariectomized OVX rats received different doses of E4 or E2V or combinations of both drugs. The concentrations of AP were assessed in the frontal and parietal cortex, hippocampus, hypothalamus, anterior pituitary, and serum. RESULTS E4 did not alter AP in intact animals in any region. E4 at a dosage of 5mg/kg/day increased AP levels in different brain areas and in the serum of OVX animals. However, in the presence of estradiol, E4 showed an estrogen-antagonistic effect on the brain and serum levels of AP. CONCLUSION E4 increases the CNS and peripheral levels of AP, behaving as a weak estrogen-agonist in OVX rats. The antagonistic effect observed with E2V co-administration further profile E4 as a natural SERM.

Abstract
INTRODUCTION Laparoscopic myomectomy has recently gained wide acceptance but this procedure remains technically highly demanding and concerns have been raised about the increased blood loss and an higher risk of postoperative uterine rupture of the pregnant uterus. OBJECTIVE The aim of the present study is to evaluate the fertility and endocrine outcome in women underwent robot-assisted laparoscopic myomectomy (RALM). METHODS Data from 48 RALM performed in our department between the years 2007 and 2011 have been collected. Conception rate, abortion rate, incidence of feto-maternal morbidity or severe pregnancy and labor-related complications were reported; FSH and AMH levels and ultrasound valuation of AFC has been made before and 6 months after operation. Number of cesarean sections and vaginal deliveries were described. RESULTS The average age of the patients was 35 years and median Body Mass Index was 23 kg/m(2) (range 18-35 kg/m(2)). Seven women (13%) became pregnant after RALM with eight pregnancies. One pregnancy is actually on going; there were six deliveries with caesarian section and one spontaneous delivery. No spontaneous abortions. No uterine ruptures occurred. No significant modification of ovarian function was found after myomectomy. CONCLUSION RALM seems to have a favorable impact on the reproductive outcome of young patients with no impact on the ovarian function.

Abstract
Despite the dismal prognosis for patients with squamous cell carcinoma of the head and neck (SCCHN), there have been no novel treatments in over 40 years. Identification of novel tumor antigens in SCCHN will facilitate the identification of potential novel treatment targets. Tumor antigens are proteins selectively expressed by tumor cells and recognized by the host immune system. Phage-displayed tumor antigens were enriched by biopanning with normal and then SCCHN-specific serum. Ninety-six phage clones were sequenced for identification, and 21 clones were validated using Luminex. One of these proteins, L23, a novel tumor antigen in SCCHN, was validated as an oncogene. L23 is upregulated in SCCHN compared with normal keratinocytes. Knockdown of L23 inhibited proliferation, invasion and cell survival. Overexpression of L23 had the reverse effect. Overexpression of L23 in non malignant cells led to transformation. Injection of SCCHN cells with knockdown of L23 in mice, induced tumors that were significantly smaller than control tumors. In conclusion, the immunomic screen yielded a panel of antigens specific to SCCHN; one of these proteins, L23, is a novel oncogene in SCCHN.

Abstract
The presence of high-affinity brain-derived neurotrophic factor receptor Trk B in mouse and in human fetal oocytes, together with the presence of neurotrophins in human follicular fluid suggests a paracrine role for brain-derived neurotrophic factor (BDNF) in female biology. This study aims to evaluate if BDNF is present and quantitatively determined in human menstrual blood and endometrium. Twenty-one women were studied and subdivided in two groups: A, 11 fertile women (27 ± 2 days cycle length) and B, 10 anovulatory women and/or women with inadequate luteal phase (36 ± 2 days cycle length). In fertile women menstrual BDNF levels was higher than plasma (679.3 ± 92.2 vs 301.9 ± 46.7 pg/ml p <0.001). Similarly, in Group B, BDNF in menstrual blood was higher than plasma (386.1 ± 85.2 vs 166.8 ± 24.1 pg/ml p < 0.001). Moreover, both menstrual and plasma BDNF concentrations in Group A were significantly higher respect to Group B (679.3 ± 92.2 vs 386.1 ± 85.2 pg/ml p < 0.001; 301.9 ± 46.7 vs 166.8 ± 24.1 pg/ml p < 0.001). Immunohistochemistry evidence of BDNF in endometrium, during follicular and luteal phase, was also shown. The detection of BDNF in the human menstrual blood and endometrium further supports the role of this neurotrophin in female reproductive function.

Abstract
Individuals with autism spectrum disorders (ASD) report difficulty integrating simultaneously presented visual and auditory stimuli (Iarocci & McDonald, 2006), albeit showing enhanced perceptual processing of unisensory stimuli, as well as an enhanced role of perception in higher-order cognitive tasks (Enhanced Perceptual Functioning (EPF) model; Mottron, Dawson, Soulières, Hubert, & Burack, 2006). Individuals with an ASD also integrate auditory-visual inputs over longer periods of time than matched typically developing (TD) peers (Kwakye, Foss-Feig, Cascio, Stone & Wallace, 2011). To tease apart the dichotomy of both extended multisensory processing and enhanced perceptual processing, we used behavioral and electrophysiological measurements of audio-visual integration among persons with ASD. 13 TD and 14 autistics matched on IQ completed a forced choice multisensory semantic congruence task requiring speeded responses regarding the congruence or incongruence of animal sounds and pictures. Stimuli were presented simultaneously or sequentially at various stimulus onset asynchronies in both auditory first and visual first presentations. No group differences were noted in reaction time (RT) or accuracy. The latency at which congruent and incongruent waveforms diverged was the component of interest. In simultaneous presentations, congruent and incongruent waveforms diverged earlier (circa 150 ms) among persons with ASD than among TD individuals (around 350 ms). In sequential presentations, asymmetries in the timing of neuronal processing were noted in ASD which depended on stimulus order, but these were consistent with the nature of specific perceptual strengths in this group. These findings extend the Enhanced Perceptual Functioning Model to the multisensory domain, and provide a more nuanced context for interpreting ERP findings of impaired semantic processing in ASD.

Abstract
Polycystic ovary syndrome is one of the most common endocrine disorders in women of reproductive age. Features of PCOS are hyperandrogenism, chronic anovulation and polycystic ovaries on ultrasonography. Follicle development is a complex and carefully orchestrated phenomenon, involving gonadotropins and a rapidly expanding list of other intraovarian regulators, such as brain-derived neurotrophic factor (BDNF). The aim of this study is to evaluate BDNF in plasma and in follicular fluid in women affected by PCOS and in normal menstruating women. In PCOS patients the BDNF levels in plasma and in follicular fluid are higher than values obtained in healthy controls. Therefore we can hypothsize that high levels of luteinizing hormone, probably increase the secretion of BDNF in PCOS patients.

Abstract
Rap1GAP is a critical tumor suppressor gene that is downregulated in multiple aggressive cancers, such as head and neck squamous cell carcinoma, melanoma and pancreatic cancer. However, the mechanistic basis of rap1GAP downregulation in cancers is poorly understood. By employing an integrative approach, we demonstrate polycomb-mediated repression of rap1GAP that involves Enhancer of Zeste Homolog 2 (EZH2), a histone methyltransferase in head and neck cancers. We further demonstrate that the loss of miR-101 expression correlates with EZH2 upregulation, and the concomitant downregulation of rap1GAP in head and neck cancers. EZH2 represses rap1GAP by facilitating the trimethylation of histone 3 at lysine 27, a mark of gene repression, and also hypermethylation of rap1GAP promoter. These results provide a conceptual framework involving a microRNA-oncogene-tumor suppressor axis to understand head and neck cancer progression.
