Abstract
We present the design, description, calibration procedure, and an analysis of systematic effects for an apparatus designed to measure the rotation of the plane of polarization of a transversely polarized slow neutron beam as it passes through unpolarized matter. This device is the neutron optical equivalent of a crossed polarizer/analyzer pair familiar from light optics. This apparatus has been used to search for parity violation in the interaction of polarized slow neutrons in matter. Given the brightness of existing slow neutron sources, this apparatus is capable of measuring a neutron rotary power of dϕ/dz = 1 × 10(-7) rad/m.

Abstract
OBJECTIVE Quinoa (Chenopodium quinoa Willd.) is a seed crop rich in bioactive compounds including phytoecdysones (especially 20-hydroxyecdysone, 20HE), polyphenols, proteins and essential fatty acids. We previously reported a method to leach and concentrate quinoa bioactives into a complex phytochemical mixture termed quinoa leachate (QL). Here, we aimed to determine the effect of QL and its chemically distinct fractions on five biochemical endpoints relevant to skin care applications: (i) cell viability, (ii) matrix metalloproteinase (MMP) mRNA expression, (iii) MMP enzymatic activity, (iv) tyrosinase enzymatic activity and (v) intracellular reactive oxygen species (ROS) production. METHODS Quinoa leachate was fractionated and chemically characterized using column chromatography and liquid chromatography-mass spectrometry (LC-MS). Cell viability was determined using a MTT assay in four mammalian cell lines. MMP-1 mRNA expression was assessed in human dermal fibroblasts (HDF) via qRT-PCR. The enzymatic activity of MMP-9 and tyrosinase was measured using fluorometric and colorimetric in vitro assays, respectively. Lipopolysaccharide (LPS)-induced ROS production was determined in human dermal fibroblasts by fluorescence intensity of an oxidant-sensitive probe. RESULTS Quinoa leachate was separated into three fractions: (i) carbohydrate-rich fraction (QL-C; 71.3% w/w of QL); (ii) phytoecdysone, polyphenol and protein-rich fraction (QL-P, 13.3% w/w of QL); (iii) oil-rich fraction (QL-O, 10.8% w/w of QL). QL did not reduce cell viability in any of the four cell lines tested. QL, QL-P and QL-O each significantly inhibited MMP-1 mRNA expression in HDF at a concentration of 5 μg mL(-1) . QL and QL-P also significantly inhibited MMP-9 enzymatic activity, whereas QL-P demonstrated significant tyrosinase enzymatic inhibition. Furthermore, QL, QL-P, QL-O and 20HE significantly inhibited intracellular ROS production. CONCLUSION This study is the first to demonstrate the MMP, tyrosinase and ROS inhibiting properties of multiple different phytochemical components derived from quinoa seeds. Our work indicates that quinoa phytochemicals may play a role in the treatment and prevention of skin ageing through a multiplicity of effects.

Abstract
BACKGROUND Few data exist on the prevalence of female sexual dysfunction (FSD) in thyroid disorders. AIM We evaluated FSD in women with thyroid diseases and in control age-matched healthy women to investigate the relationship between sexual function and thyroid hormones. METHODS One hundred and four women with thyroid diseases and 53 controls participated in the study. Eighteen with hyperthyroidism (Group 1), 22 hypothyroidism (Group 2), 45 Hashimoto's thyroiditis (Group 3), 19 nodular goiter (Group 4) underwent thyroid function evaluation and sonography. The Female Sexual Function Index (FSFI) assessed sexual function. RESULTS The prevalence of FSD was 46.1% in thyroid diseases and 20.7% in controls. Only in Group 4, the prevalence (68.4%) was significantly higher than in controls (p<0.005). The mean total FSFI score was 20.1 ± 7.1 in women with thyroid diseases and 25.6 ± 4.7 in the controls (p<0.001). Compared with controls, there was a significant decrease of desire in Group 2; desire, arousal and lubrication in Group 3; desire, arousal, lubrication, orgasm and satisfaction in Group 4. In thyroid diseases the prevalence of FSD was 53% and 42%, while in the controls was 55% and 20%, in menopausal and pre-menopausal groups, respectively. We found a significant inverse correlation between TSH and FSFI (r=-0.7, p=0.01) in Group 4, which showed the lowest FSFI score (17.8 ± 5.7) and the highest body mass index (28.4 ± 7.1 kg/m(2)). CONCLUSIONS Women with thyroid diseases present a higher prevalence of FSD than controls. Although our findings suggest a higher impairment of sexual function in Group 4 and a role for TSH in FSD, further researches are needed.

Abstract
Type IIIb polyglandular autoimmune disease comprises autoimmune thyroid disease (HT) and chronic atrophic gastritis (AIG). Hypergastrinemia, secondary to AIG, predisposes to gastric enterochromaffin-like cell (ECL) hyperplasia, a preneoplastic condition. We evaluated the prevalence of AIG, hypergastrinemia and ECL hyperplasia in HT patients. A secondary end-point was to assess the efficacy of treatment with a somatostatin analogue in HT patient with ECL hyperplasia. From 2009 to 2011, 146 HT patients were enrolled in a prospective study. All cases underwent hormonal profile, and parietal cell antibody (PCA), gastrin, and chromogranin A (CgA) serum level assays. Selected patients with elevated gastrin and CgA levels underwent gastro esophageal endoscopy (EGDS). Patients positive for ECL hyperplasia received Octreotide LAR 30 mg/28 days for 12 months. Gastrin and CgA assays were repeated every three months and EGDS after one year. The results show that gastrin and CgA were significantly higher than normal in 17/115 (14.7%) patients. Seven more HT had isolated PCA positivity and in the 17 PCA positive patients histology diagnosed AIG, corpus prevalent, with mild to moderate atrophy. Diffuse ECL hyperplasia of the gastric body was present in three subjects, one of them presenting a type-1 carcinoid. Gastrin and CgA levels were significantly reduced (p<0.01) after 3 months of therapy with a somatostatin analogue and returned to normal after 1 year. ECL hyperplasia regressed in all three patients. We suggest that selected HT patients may need a more accurate surveillance for early signs of gastric EC risk. In the case of altered values of gastrin and in the presence of PCA positivity, EGDS and histology should be performed for an early diagnosis of AIG and treatment of ECL hyperplasia.

Abstract
Multiple endocrine neoplasia syndromes have since been classified as types 1 and 2, each with specific phenotypic patterns. MEN1 is usually associated with pituitary, parathyroid and paraneoplastic neuroendocrine tumours. The hallmark of MEN2 is a very high lifetime risk of developing medullary thyroid carcinoma (MTC) more than 95% in untreated patients. Three clinical subtypesdMEN2A, MEN2B, and familial MTC (FMTC) have been defined based on the risk of pheochromocytoma, hyperparathyroidism, and the presence or absence of characteristic physical features). MEN2 occurs as a result of germline activating missense mutations of the RET (REarranged during Transfection) proto-oncogene. MEN2-associated mutations are almost always located in exons 10, 11, or 13 through 16. Strong genotype-phenotype correlations exist with respect to clinical subtype, age at onset, and aggressiveness of MTC in MEN2. These are used to determine the age at which prophylactic thyroidectomy should occur and whether screening for pheochromocytoma or hyperparathyroidism is necessary. Specific RET mutations can also impact management in patients presenting with apparently sporadic MTC. Therefore, genetic testing should be performed before surgical intervention in all patients diagnosed with MTC. Recently, Pellegata et al. have reported that germline mutations in CDKN1B can predispose to the development of multiple endocrine tumours in both rats and humans and this new MEN syndrome is named MENX and MEN4, respectively. CDKN1B. A recent report showed that in sporadic MTC, CDKN1B V109G polymorphism correlates with a more favorable disease progression than the wild-type allele and might be considered a new promising prognostic marker. New insights on MEN syndrome pathogenesis and related inherited endocrine disorders are of particular interest for an adequate surgical and therapeutic approach.

Abstract
The miR-106b-25 microRNA (miRNA) cluster is a candidate oncogene in human prostate cancer. Here, we report that miRNAs encoded by miR-106b-25 are upregulated in both primary tumors and distant metastasis. Moreover, increased tumor miR-106b expression was associated with disease recurrence and the combination of high miR-106b and low CASP7 (caspase-7) expressions in primary tumors was an independent predictor of early disease recurrence (adjusted hazard ratio=4.1; 95% confidence interval: 1.6-12.3). To identify yet unknown oncogenic functions of miR-106b, we overexpressed it in LNCaP human prostate cancer cells to examine miR-106b-induced global expression changes among protein-coding genes. The approach revealed that CASP7 is a direct target of miR-106b, which was confirmed by western blot analysis and a 3'-untranslated region reporter assay. Moreover, selected phenotypes induced by miR-106b knockdown in DU145 human prostate cancer cells did not develop when both miR-106b and CASP7 expression were inhibited. Further analyses showed that CASP7 is downregulated in primary prostate tumors and metastatic lesions across multiple data sets and is by itself associated with disease recurrence and disease-specific survival. Using bioinformatics, we also observed that miR-106b-25 may specifically influence focal adhesion-related pathways. This observation was experimentally examined using miR-106b-25-transduced 22Rv1 human prostate cancer cells. After infection with a miR-106b-25 lentiviral expression construct, 22Rv1 cells showed increased adhesion to basement membrane- and bone matrix-related filaments and enhanced soft agar growth. In summary, miR-106b-25 was found to be associated with prostate cancer progression and disease outcome and may do so by altering apoptosis- and focal adhesion-related pathways.

Abstract
BACKGROUND Recombinant-FSH (rFSH) added to hCG at dose of 450 IU weekly is effective in inducing spermatogenesis in patients with hypogonadotropic hypogonadism (HH), but there are no data on the use of lower doses. AIM This observational retrospective study evaluated whether 150-225 IU of rFSH weekly were able to induce spermatogenesis in HH men who failed to start it with hCG alone. SUBJECTS AND METHODS Thirty-four patients with pre-pubertal onset HH (20-44 yr old) without adverse fertility factors were considered for this study. After hCG pre-treatment they received also either rFSH (Group 1) or highly purified urinary FSH (hpFSH) (Group 2) 75 IU sc 2 or 3 times weekly. Semen analysis was performed every 3 months during pre-treatment and the 1st yr of combined therapy. Patients were also invited to refer pregnancies in their partners during the subsequent 12 months. RESULTS Total sperm count/ejaculate did not show significant difference between 2 groups, while a significantly higher forward motility was observed in Group 1 (p<0.05). The median times to achieve sperm output thresholds (first sperm appearance, sperm concentration >1.5 or >5 mil/ml) were significantly lower in Group 1 (p<0.04, 0.03, and 0.001, respectively). A tendency to a shorter time to pregnancy was shown in partners of Group 1. CONCLUSIONS Our data indicate that lower rFSH week dose than that so far used was able to induce potentially fertilizing sperm output in HH men previously treated with hCG. The rFSH effects are comparable to those of hpFSH but with a trend to a faster outcome achievement.

Abstract
The deficiency of carbon nanotube (CNT) growth on temperature-sensitive substrates such as plastic tapes impedes the further progress in CNT electronics. We report a novel method that is able to offer the solution by selectively delivering energy via high radio frequency heating to carbon atoms for their catalytic assembly into individual CNTs. Direct growth of CNTs on a flexible kapton substrate was demonstrated. A mechanism of selective heating was discussed.

Abstract
AIM Differentiation toward the osteoblastic phenotype is a complex phenomenon regulated by means of several factors. Numerous studies in vitro et in vivo showed that surface properties of titanium dental implants modulate cell proliferation and osteoblastic differentiation, affecting bone healing processes. Optimal superficial morphology is still controversial. The aim of the present study was to evaluate in vitro the effects of two different titanium surfaces on biological behaviour of human osteoblast-like cells SaOS-2 with regard to production of extra-cellular matrix (ECM) proteins. METHODS Human osteoblast-like cells SaOS-2, cultured on commercially pure titanium disks with two different surface topographies, smooth and microstructured with sand-blasting and acid-etching treatment, were evaluated by investigating adhesion, proliferation and deposition of extra-cellular matrix (ECM) proteins Fibronectin, Tenascin and Collagen I. RESULTS The different values of cellular adhesion at three hours and the increase of SaOS-2 proliferation values at the different experimental times on both evaluated surfaces didn't result statistically significant. ECM deposition analysis showed that Fibronectin, Tenascin and Collagen I were gradually produced, with not statistically significant differences for Fibrone-ctin and Tenascin and statistically significant differences for Collagen I. CONCLUSION Implant surface properties modulate in vitro the biological behavior of osteoblasts-like cells SaOS-2. SaOS-2 cells proliferate on both evaluated surfaces, showing a more organized differentiation towards an osteoblastic phenotype in ECM proteins production when cultured on microstructured surface.

Abstract
The evaluation of the patient satisfaction in primary care is quite difficult to evaluate for lack of appropriate indicators. The objectives of this study were the validation of the method, using the Picker Institute's Inpatient Questionnaire, and the assessment of patient judgment about the quality of primary care in the DS 50. The indicators that have been used included 3 areas: communication, organization and patient-staff relationship. The results showed that the patient-staff relationship area was indicated as the most important for the patients and they pointed out several problem either for human (self-reference of the professional, lack of emotional relationship) and or for organizational aspects (waiting time). The study highlight that in order to improve the utility of such method, the health organization must be able to appropriately evaluate the patients' need, setting them in a specific organizational vision.

Abstract
The aim in the current study was to investigate the efficacy of the PECS (Picture Exchange Communication System) in a sample of children with Autistic Disorder (AD) in the development of the communication, alternating gaze and pointing in children with Autistic Disorder (AD).The sample included 5 children diagnosed with AD (DSM-IV-TR), no verbal language, followed by the team of the Rehabilitation Centre belonging to Scientific Institute “E. Medea”, Association “La Nostra Famiglia” Branch of Ostuni (Italy). The children were tested on their ability with neuropsychiatric, psycholinguistics and psychological assessment at the pre and post of the trial.The treatment PECS has gone on for two years with a frequency of three times a week (45 minutes each one).The observed behavioral variables were: spontaneous request of objects using the notebook PECS, alternating gaze, pointing, and possible vocalizing and verbalizing on imitation.The data were collected at the beginning and at the end of the trial, using play-interaction videotapes, lasting 20 minutes each. Segments (10 min) of videos were randomly selected for coding.The behaviours were coded using the Observer XT. 7 and the results were analyzed statistically with the SPSS programme.The results show a significant increase in the number of spontaneous requests, in the capacity of alternating gaze, pointing, vocalizing and verbalizing on imitation.Finally the PECS seems to allow not only to develop a functional communication in AD, but also to increase social communicative behaviours of children with AD. Nevertheless further studies are necessary.

Abstract
It is known that hypopituitarism reduces life expectancy and increases the risk of death for cardio- and cerebrovascular disease. Many studies report this phenomenon due to vascular diseases, and GH deficiency (GHD) seems to significantly contribute to the higher mortality. Aim of this article is to review the relationship between GH and cardiovascular risk factors to evaluate the beneficial effects of therapy in the adult GHD. GH replacement therapy (GHRT) improves insulin sensitivity, and reduces LDL cholesterol and triglyceride levels. Several studies also documented a decrease in the intima-media thickness at major arteries and improvement in microvascular and endothelial function. Other studies showed a decrease of inflammatory markers and the normalization of coagulation parameters. Finally, some authors have reported improvements in cardiac performance as well. These data evidence the positive effects of GHRT in the prevention of premature atherosclerosis in adults with GHD, and encourage the early administration of replacement therapy.

Abstract
AIM Gastric cancer is the fifth most common cause of tumor-related death in Western countries. Surgery is the only effective treatment but only 50-60% of patients can receive a curative treatment because of absent or aspecific symptoms. The aim of this study was to develop a scale for gastric cancer patients that takes into account factors related to the tumor and to the patient. METHODS Fifty-seven patients with gastric adenocarcinoma admitted to the Department of General, Geriatric Surgery and Diagnostic and Operative Endoscopy of the University ''Federico II'' in Naples, and treated by gastrectomy from January 1998 until December 2002, were included in this retrospective cohort. The prognostic score was created according to the variables identified in Cox analysis as statistically significant (P 0.1). RESULTS The 5-year mortality rate was 61%. Cox analysis identified these variables with a significant effect on mortality: age ?60 (odds ratio (OR) 4.16; P=0.015), smoking or alcoholism (OR 2.66; P=0.057), pTNM I (OR 0.04; P=0.003), pTNM II (OR 0.18; P=0.029), pTNM III (OR 0.27; P=0.023), pTNM IV (OR 3.28; P=0.012), lymph node ratio (LNR) <20% (OR 0.15; P=0.01), LNR 20% (OR 3.83; P=0.002), Lauren diffuse histotype (OR 2.41; P=0.1) and location of the neoplasm at superior third (OR 6.70; P=0.003), middle third (OR 5.60; P=0.003), or inferior third (OR 0.32; P=0.008). Patients have been randomized into three groups according to their scores (3-40.5; 41-78.5; 79-115.5) and the 5-year mortality rate was 46%, 59%, 90% in group 1, 2 and 3 respectively. CONCLUSION It is necessary to consider in prognostic stratification of gastric cancer patients not only pTNM staging but also other factors such as age, smoking or alcoholism, Lauren histotype, location and linfonodal involvement. It is possible to design a more effective prognostic score predicting the individual risk and addressing the therapy and the follow-up.

Abstract
We report a patient with a right cortical and subcortical temporo-occipital lesion who showed spatial neglect mainly involving the left and the near peripersonal space. In drawing tasks the patient omitted the elements closer to him within each figure. A copying task with pairs of radially aligned line drawings demonstrated that the patient's radial neglect was based on within-object coordinates. This novel observation extends the egocentric-allocentric distinction to the radial dimension.

Abstract
The entero-cutaneous fistulas (ECF) are abnormal communications between intestine and abdominal skin. They can occur spontaneously, or after an injury or a surgical procedure. They are associated with a high rate of morbidity and mortality. Spontaneous fistulas can mainly occur in patients affected by cancer, inflammatory bowel disease, diverticulitis, appendicitis, as a result of radiotherapy or injuries. Surgical procedures, carried out in case of neoplastic diseases, inflammatory bowel disease, adhesions removal, represent the primary cause in the development of a postoperative fistulas. Malnourishment, poor general conditions of the patient, high output fistula along with anatomical site of development, and the presence of abscesses, represent the negative factors influencing the spontaneous healing of fistulas. The experience reported here is about three ECF cases occurred after surgery and treated only with medical therapy. The first case is a woman in good general conditions who underwent surgery to remove a recurrent retroperitoneal myxoid liposarcoma situated in the right lower quadrant. The patient had never undergone surgery for an intestinal resection. The other two patients analyzed were affected by sepsis and metabolic unbalance and had developed a fistula after colonic resection. Fluids and electrolytes adjustments and sepsis management have preceded any other kind of therapy. Continuous infusion with somatostatin, fast, proton pump inhibitors and loperamide have been taken up to decrease secretions and intestinal motility. Total parenteral nutrition has been essential to recover nutritional status and improve patients' general conditions. In order to heal and protect peri-fistula skin we have used sterile washing solutions, absorbable ionic exchange resin, silver and polyurethanes based medications and colostomy bags adhesive systems. Since surgical treatment of ECF is associated with high rates of morbidity and mortality, conservative treatment should always be taken into consideration. When conservative treatment fails, delayed surgical intervention has been related to a higher rate of success. The purpose of this study is to describe diagnostic and therapeutic guidelines to general surgeons, like ourselves, whenever they have to deal with ECF cases.

Abstract
This study values the effectiveness of nutrition education interventions carried out by teachers with active didactic methodologies. The research was carried out by administering a frequency of food intake questionnaire, before and after the intervention. To compare the answers given before and after the educational intervention the Wilcoxon-test was applied to dependent data. Our research confirmed that a substantial percentage of children do not show a correct nutrition and therefore nutrition education interventions are opportune and necessary. In the group with "insufficient execution" particular variations are not taken place. In the group with "sufficient execution" increase the number of subjects having breakfast, particularly with milk and biscuits, and decrease the snakes intake. Moreover there is a general decrease of intake food as meat, fish, vegetables, salami and legumes. So this educational intervention seems to have only partial effectiveness.
