Abstract
Tetrabromobisphenol A-TBBPA, a widely used brominated flame retardant detected in aquatic environments, is considered a potential endocrine disruptor-ED for its reproductive/developmental effects in vertebrates. In aquatic invertebrates, the modes of action of most EDs are largely unknown, due to partial knowledge of the mechanisms controlling neuroendocrine functions. In the marine bivalve Mytilus galloprovincialis, TBBPA has been previously shown to affect larval development in the 48 h larval toxicity assay at environmental concentrations. In this work, the effects of TBBPA were further investigated at different times post-fertilization. TBBPA, from 1 μg/L, affected shell biogenesis at 48 hours post fertilization-hpf, as shown by phenotypic and SEM analysis. The mechanisms of action of TBBPA were investigated at concentrations of the same order of magnitude as those found in highly polluted coastal areas (10 μg/L). At 28-32 hpf, TBBPA significantly affected deposition of both the organic matrix and CaCO3 in the shell. TBBPA also altered expression of shell-related genes from 24 to 48 hpf, in particular of tyrosinase, a key enzyme in shell matrix remodeling. At earlier stages (24 hpf), TBBPA affected the development of dopaminergic, serotoninergic and GABAergic systems, as shown by in situ hybridization-ISH and immunocytochemistry. These data contribute draw adverse outcome pathways-AOPs, where TBBPA affects the synthesis of neutrotransmitters involved in key events (neurodevelopment and shell biogenesis), resulting in phenotypic changes on individuals (delayed or arrested development) that might lead to detrimental consequences on populations.

Abstract
Morvan's syndrome (MoS) is a rare autoimmune disorder characterized by central nervous system involvement, autonomic dysfunction and peripheral nerve hyperexcitability. MoS is believed to be caused by autoantibodies targeting contactin-associated protein 2 (Caspr2), a subunit of the neuronal voltage-gated potassium channel (VGKC) complex, usually in association with thymoma, less commonly with other malignancies. This case highlights an exceptional case of severe sleep disturbances and behavioural changes due to MoS, in a patient who would present with and be treated successfully for a second relapse of thymoma 30 months later. Originally he suffered from ocular myasthenia, another autoimmune disorder, which led to diagnosis of his original thymoma and first relapse.

Abstract
Abstract
BACKGROUND
Glioblastoma multiforme (GBM) is the most malignant primary brain cancer. Several mutations and alterations of key cellular pathways including tyrosine kinases (TKs) are involved in GBM etiopathogenesis. Currently there is no cure for GBM. Tumour heterogeneity and the presence of the blood brain barrier (BBB), with efflux transporters, are some of the causes of failure of novel therapeutic agents. Thus, appropriate target selectivity and pharmacokinetics (including brain penetration) are critical issues for the generation of potential drug candidates. The main in-vitro and in-vivo properties and antitumour activity of CR13626, a novel brain penetrant TK inhibitor, are presented.
MATERIAL AND METHODS
CR13626 inhibitory activity against a panel of 173 kinases was assessed. The effect on cellular proliferation was verified in different 2D human glioblastoma cell lines (U87MG, U373, U87MG vIII) and in a U87MG 3D spheroid model by ViaCount assays. The in-vivo antitumour activity was determined in a mouse model of glioblastoma based on the orthotopic injection of U87MG-Luciferase GBM cells in nude mice: oral treatment started on day 9 post-implantation and continued for 10 days (50 mg/kg/daily). Tumour progression was evaluated through the measurement of bioluminescence (BLI) at the end of dosing (day 19) and during follow-up (day 26–33). Survival was also monitored. The pharmacokinetics and brain exposure of CR13626 were assessed by LC/MS/MS in plasma and brain homogenate tissues of CD1 and tumour-bearing nude mice.
RESULTS
CR13626 potently inhibited FYN, YES, KDR and EGFR kinases, relevant for GBM development, with IC50 values of 69 nM, 3.6 nM, 82 nM and 6 nM, respectively. The compound reduced the proliferation of different human glioblastoma cell lines (GI50 1–3 µM). In CD1 mice, CR13626 had a good oral bioavailability (72%) and brain penetration (brain/plasma ratio of 1.4). In-vivo BLI analysis indicated a time-dependent reduction of tumour growth, reaching 60% on the last BLI evaluation 33 days post-implantation (i.e. 15 days after the end of dosing). Tumour growth inhibition translated into an increase of 25% of the median survival time of animals treated with CR13626 compared to the vehicle group (p<0.05). The observed antitumour effects agreed with the exposure of tumour-bearing mice to CR13626, which was above the TKs in-vitro IC50 values.
CONCLUSION
The combined abilities of CR13626 to inhibit the activity of TKs involved in GBM development, to cross the BBB, and to reduce tumour growth in-vivo leading to increased survival, warrant its further development as a drug candidate in GBM.

Abstract
Cerium nanoparticles (nCeO2) are increasingly utilized in a wide variety of industrial, environmental and biomedical applications, and are therefore expected to be released in the aquatic environment. Due to its peculiar redox properties, nCeO2 may present unique hazards to environmental and human health. Previous data showed that in the hemocytes of the marine bivalve Mytilus galloprovincialis, in vitro exposure to a particular type of nCeO2 (9 nm, characterized by negative ζ-potential, high H2O2 scavenging capacity and Ce3+/Ce4+ surface ratio) reduced basal ROS production, lysosomal membrane stability and phagocytic activity in the presence of hemolymph serum; the effects observed were partly ascribed to the formation of a SOD-protein corona in the hemolymph. In this work, the in vivo effects of this type of nCeO2 were investigated in mussels exposed to 100 μg/L nCeO2 for 96 h; several lysosomal, immune, inflammatory and antioxidant biomarkers were measured at cellular (hemocytes) and tissue (gills, digestive gland) level. Molecular responses were evaluated in hemocytes and digestive gland by determining expression of 11 selected genes related to known biological functions. The results show specific immunomodulatory and antioxidant effects of nCeO2 at different levels of biological organization in the absence of Cerium tissue accumulation. These data further support the redox mechanisms at the basis of the physiological effects of nCeO2. Finally, in order to evaluate the possible impact at the whole organism level, the effects of nCeO2 were evaluated in the 48 h embryotoxicity assay in a wide concentration range. However, nCeO2 exposure resulted in a small reduction in normal embryo development. Overall, the results demonstrate that in mussels nCeO2 can selectively modulate different physiological processes at different levels of biological organization.

Abstract
Efficient enantiodiscrimination of some alanine-containing di- and tri-peptides by using chiral protonated bis(diamido)-bridged basket resorcin[4]arenes depends on several factors, including the basicity of the amino acid residues at the C- and N-termini of the peptide.

Abstract
The yeast Wickerhamomyces anomalus has been studied for its wide biotechnological potential, mainly for applications in the food industry. Different strains of W. anomalus have been isolated from diverse habitats and recently from insects, including mosquitoes of medical importance. This paper reports the isolation and phylogenetic characterization of W. anomalus from laboratory-reared adults and larvae of Phlebotomus perniciosus (Diptera: Psychodidae), a main phlebotomine vector of human and canine leishmaniasis. Of 65 yeast strains isolated from P. perniciosus, 15 strains were identified as W. anomalus; one of these was tested for the killer phenotype and demonstrated inhibitory activity against four yeast sensitive strains, as reported for mosquito-isolated strains. The association between P. perniciosus and W. anomalus deserves further investigation in order to explore the possibility that this yeast may exert inhibitory/killing activity against Leishmania spp.

Abstract
OBJECTIVE Incidence of intrahepatic mass-forming cholangiocarcinoma (IMCC) is increasing worldwide, especially in patients with chronic liver disease. The small and the histologically well-differentiated IMCCs in chronic liver disease could be arterially hypervascular lesions with/without washout on computed tomography (CT) and magnetic resonance imaging (MRI), mimicking typical hepatocellular carcinoma (HCC). The aim of this work is to evaluate contrast enhancement (CE) patterns of IMCCs at quadri-phasic multidetector CT (4-MDCT) and MRI, using imaging-clinicopathologic correlation. PATIENTS AND METHODS The 4-MDCT and MR images of 56 histologically confirmed IMCCs were retrospectively evaluated for tumor morphology and enhancement features. Enhancement pattern was defined according to the behavior of the nodule in arterial (AP), portal venous (PVP) and equilibrium phases (EP), and dynamic pattern was described according to enhancement progression throughout the different phases. Arterial and dynamic enhancement patterns were correlated with chronic liver disease, tumor size and histological differentiation. RESULTS Most of the nodules were peripherally hyperenhancing (50%) on AP, and partially hyperenhancing on PVP (67.9%) and EP (80.3%). Forty-six (82.1%) IMCCs showed progressive CE, 7 (12.5%) stable CE and 3 (5.4%) wash-out. In normal liver there were 34 nodules with progressive and 3 with stable CE, whereas in chronic liver disease there were 12 IMCCs with progressive, 4 with stable and 3 with washout pattern (p = 0.01); IMCCs with progressive CE were more differentiated than IMCCs with stable CE and wash-out (p = 0.02). CONCLUSIONS The most prevalent enhancement pattern of IMCCs was arterial rim enhancement followed by progressive and concentric filling. The stable and the washout patterns were more frequent in poorly differentiated IMCCs. Contrast washout was observed only in IMCCs emerging in chronic liver disease with a risk of misdiagnosis with HCC.

Abstract
Male breast cancer (MBC) is rare and poorly understood. Like female breast cancer (FBC), MBCs are highly sensitive to hormonal changes, and hyperestrogenism, specifically, represents a major risk factor for MBC. MBC is considered similar to late-onset, post-menopausal estrogen/progesteron receptors positive FBC (ER+/PR+). Sulfotransferase 1A1 (SULT1A1) is an enzyme involved in the metabolism of estrogens. Recently, SULT1A1 common functional polymorphism Arg(213)His (638G>A) variant has been found to be associated with increased breast cancer (BC) risk, particularly in post-menopausal women. For this reason, we decided to explore whether SULT1A1 Arg(213)His could exert an effect on MBC development. The primary aim of this study was to evaluate the influence of the SULT1A1 Arg(213)His polymorphism on MBC risk. The secondary aim was to investigate possible associations with relevant clinical-pathologic features of MBC. A total of 394 MBC cases and 786 healthy male controls were genotyped for SULT1A1 Arg(213)His polymorphism by PCR-RFLP and high-resolution melting analysis. All MBC cases were characterized for relevant clinical-pathologic features. A significant difference in the distribution of SULT1A1 Arg(213)His genotypes was found between MBC cases and controls (P < 0.0001). The analysis of genotype-specific risk showed a significant increased MBC risk in individuals with G/A (OR 1.97, 95% CI 1.50-2.59; P < 0.0001) and A/A (OR 3.09, 95% CI 1.83-5.23; P < 0.0001) genotypes in comparison to wild-type genotype, under co-dominant model. A significant association between SULT1A1 risk genotypes and HER2 status emerged. Results indicate that SULT1A1 Arg(213)His may act as a low-penetrance risk allele for developing MBC and could be associated with a specific tumor subtype associated with HER2 overexpression.

Abstract
PURPOSE To evaluate in current practice the performance of BOADICEA and BRCAPRO risk models and empirical criteria based on cancer family history for the selection of individuals for BRCA genetic testing. PATIENTS AND METHODS The probability of BRCA mutation according to the three tools was retrospectively estimated in 918 index cases consecutively undergone BRCA testing at 15 Italian cancer genetics clinics between 2006 and 2008. RESULTS 179 of 918 cases (19.5%) carried BRCA mutations. With the strict use of the criteria based on cancer family history 173 BRCA (21.9%) mutations would have been detected in 789 individuals. At the commonly used 10% threshold of BRCA mutation carrier probability, the genetic models showed a similar performance [PPV (38% and 37%), sensitivity (76% and 77%) and specificity (70% and 69%)]. Their strict use would have avoided around 60% of the tests but would have missed approximately 1 every 4 carriers. CONCLUSION Our data highlight the complexity of BRCA testing referral in routine practice and question the strict use of genetic models for BRCA risk assessment.

Abstract
Palivizumab (Synagis®) is a humanized monoclonal antibody (IgG1K) composed of 95% human and 5% murine sequences. It is directed to an epitope in the A antigenic site of the F protein of respiratory syncytial virus (RSV). Palivizumab is used for prevention of serious lower respiratory tract disease caused by RSV in pediatric patients who are at increased risk of severe disease and is administered intramuscularly (IM) for a total of 5 monthly doses. Herein, we report on the development and validation of a very sensitive enzyme-linked immunosorbent assay (ELISA) to measure serum concentrations of palivizumab by a rabbit polyclonal antibody specifically produced against the murine sequence. The method was developed and validated according to the guidelines “Guidance for Industry” (1998) and has proved suitable for the determination of palivizumab serum levels in the target infant population. The ELISA assay was successfully applied to test the serum samples in an infant population who received palivizumab intramuscularly; thus, the assay could be used to determine serum levels in palivizumab-treated infants to optimize dosing and scheduling and to study the relationship between dose and clinical response.

Abstract
It is well-known that male breast cancer (MBC) susceptibility is mainly due to high-penetrance BRCA1/2 mutations. Here, we investigated whether common low-penetrance breast cancer (BC) susceptibility alleles may influence MBC risk in Italian population and whether variant alleles may be associated with specific clinicopathological features of MBCs. In the frame of the Italian Multicenter Study on MBC, we genotyped 413 MBCs and 745 age-matched male controls at 9 SNPs annotating known BC susceptibility loci. By multivariate logistic regression models, we found a significant increased MBC risk for 3 SNPs, in particular, with codominant models, for rs2046210/ESR1 (OR = 1.71; 95 % CI: 1.43-2.05; p = 0.0001), rs3803662/TOX3 (OR = 1.59; 95 % CI: 1.32-1.92; p = 0.0001), and rs2981582/FGFR2 (OR = 1.26; 95 % CI: 1.05-1.50; p = 0.013). Furthermore, we showed that the prevalence of the risk genotypes of ESR1 tended to be higher in ER- tumors (p = 0.062). In a case-case multivariate analysis, a statistically significant association between ESR1 and ER- tumors was found (OR = 1.88; 95 % CI: 1.03-3.49; p = 0.039). Overall, our data, based on a large and well-characterized MBC series, support the hypothesis that common low-penetrance BC susceptibility alleles play a role in MBC susceptibility and, interestingly, indicate that ESR1 is associated with a distinct tumor subtype defined by ER-negative status.

Abstract
Erbium activated PbO-ZnO tellurite glasses ((70TeO(2)-(30-x)ZnO-xPbO)(0.99)-(Er(2)O(3))(0.01) (TZPE), (x = 5, 10, 15, 20)) were prepared by a melt quenching process and studied by optical absorption, luminescence, Raman and x-ray absorption spectroscopy measurements as a function of the PbO/ZnO ratio. The glass structure, as monitored by Raman scattering, shows important changes with the PbO/ZnO ratio, attributed to a glass former action of PbO. The local environment of Er(3+) ions, as measured by extended x-ray absorption spectroscopy, does not appreciably change as regards the first oxygen shell. However, the intensity of the optical transitions is quite sensitive to the PbO/ZnO ratio, indicating a progressive increase of the site symmetry with the PbO content. The emission probability and radiative lifetime of several excited states of Er(3+) ions were calculated using Judd-Ofelt analysis.

Abstract
Background: In this study we aimed to evaluate the role of a SNP in intron 1 of the ERCC4 gene (rs744154), previously reported to be associated with a reduced risk of breast cancer in the general population, as a breast cancer risk modifier in BRCA1 and BRCA2 mutation carriers. Methods: We have genotyped rs744154 in 9408 BRCA1 and 5632 BRCA2 mutation carriers from the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA) and assessed its association with breast cancer risk using a retrospective weighted cohort approach. Results: We found no evidence of association with breast cancer risk for BRCA1 (per-allele HR: 0.98, 95% CI: 0.93–1.04, P=0.5) or BRCA2 (per-allele HR: 0.97, 95% CI: 0.89–1.06, P=0.5) mutation carriers. Conclusion: This SNP is not a significant modifier of breast cancer risk for mutation carriers, though weak associations cannot be ruled out.

Abstract
Alemtuzumab is a humanized (IgG(1)) rat monoclonal antibody to CD52 antigen and is currently used in the treatment of chronic lymphocytic leukemia (CLL) and other CD52-positive lymphoproliferative disorders. Various techniques have been developed to measure Alemtuzumab levels in human serum/plasma. The authors report on the validation of a very sensitive enzyme-linked immunosorbent assay (ELISA) to measure serum concentrations of the humanized IgG(1) using a rabbit polyclonal antibody specifically produced against the rat sequence of Alemtuzumab after papain digestion. The assay was successfully applied to test the serum samples of patients with B-lymphocyte CLL who received Alemtuzumab subcutaneously. This ELISA assay could be easily used to determine human serum levels of Alemtuzumab pre- and post-treatment to optimize dosing and scheduling and to study the relationship between dose and clinical response.

Abstract
BRCA1 and 2 are major cancer susceptibility genes but their penetrance is highly variable. The folate metabolism plays an important role in DNA methylation and its alterated metabolism is associated with cancer risk. The role of allele variants 677T and 1298C (MTHFR gene) and 2756G (MS gene) has been investigated as potentially modifying factors of BRCA gene penetrance, evaluated as age at first diagnosis of cancer, in 484 BRCA1/BRCA2 carriers and in 108 sporadic breast cancer cases as a control group. The genotype analysis has been performed by means of PCR/RFLP's. The analysis of association between a particular genotype and disease risk was performed using Cox Regression with time to breast or ovarian cancer onset as the end-point. The presence of 677T allele confers an increased risk of breast cancer in BRCA1 carriers (P = 0.007) and the presence of 1298C allele confers an increased risk of breast cancer in sporadic cases (P = 0.015).

Abstract
BACKGROUND BRCA1 and BRCA2 are the two major genes responsible for the breast and ovarian cancers that cluster in families with a genetically determined predisposition. However, regardless of the mutation detection method employed, the percentage of families without identifiable alterations of these genes exceeds 50%, even when applying stringent criteria for family selection. A small but significant increase in mutation detection rate has resulted from the discovery of large genomic alterations in BRCA1. A few studies have addressed the question of whether BRCA2 might be inactivated by the same kinds of alteration, but most were either done on a relatively small number of samples or employed cumbersome mutation detection methods of variable sensitivity. OBJECTIVE To analyse 121 highly selected families using the recently available BRCA2 multiplex ligation dependent probe amplification (MLPA) technique. RESULTS Three different large genomic deletions were identified and confirmed by analysis of the mutant transcript and genomic characterisation of the breakpoints. CONCLUSIONS Contrary to initial suggestions, the presence of BRCA2 genomic rearrangements is worth investigating in high risk breast or ovarian cancer families.

Abstract
The aim of this study was to evaluate the performance of a technique for the simultaneous testing of opiates, cocaine and metabolites in hair by interlaboratory comparison. Sixteen forensic and clinical laboratories with different degrees of experience in hair analysis participated voluntarily in the study (no selection criteria were applied). The suggested analytical procedure, the one routinely used in our laboratory, consisted of incubation in HCl 0.1N (45 degrees C, overnight), solid phase extraction (with Bond Elut Certify) cartridges), derivatisation (trimethylsilyl (TMS) derivatives) and GC-MS analysis. Three different mixtures of finely cut (1 mm or less) hair were prepared using drug-users' and drug-free hair: one 'negative' sample (<0.1 ng/mg for morphine, 6-acetylmorphine (6AM), cocaine and benzoylecgonine (BE)), one 'low concentration' sample (between 0.5 and 2 ng/mg) and one 'high concentration' sample (>3 ng/mg). Accuracy and precision (CV% lower than 5.1, 9.9, 5.2, 3.8, 7.3 and 8.3% for morphine, 6AM, codeine, cocaine, BE, and methylecgonine (ME), respectively; range 0.5-5 ng/mg) of the method and homogeneity of the mixtures were evaluated in our laboratory by intraday (CV% lower than 12% for all analytes) and interday analyses (CV% lower than 17% for all analytes except 6AM, 25%). Participants in the study were grouped into: (1) laboratories (n = 6) obtaining the best qualitative and quantitative values, corresponding to those with long experience in hair analysis; (2) laboratories (n = 5) with no reported false positive and/or false negatives; (3) laboratories (n = 5) with one or more reported false positives/false negatives. The results obtained by the labs of the first group were used as reference values. The scatter of data was similar to those obtained in other published studies.

Abstract
OBJECTIVE To compare the plasma pharmacokinetics of lamivudine 150mg twice daily and 300mg once daily in patients with HIV-1 infection. DESIGN Nonblind, sequential, pharmacokinetic study. PARTICIPANTS 13 patients with HIV-1 infection (median age 36 years). METHODS Patients were tested during twice daily and then once daily regimens of lamivudine. In both regimens, the total daily dose of lamivudine was identical (300 mg/day). Blood samples for pharmacokinetic analysis were taken over a 12-hour period after > or =7 days of twice daily administration, and again over a 24-hour period after 7 days of once daily administration,. RESULTS 12 patients completed the study. Lamivudine pharmacokinetic parameters (mean +/- SD) after administration of 150mg twice daily were: peak plasma concentration (Cmax) 2077+/-816 microg/L; trough plasma concentration (Cmin) 332+/-219 microg/L; elimination half-life (t 1/2beta) 6.1+/-1.9h; time to Cmax (t(max)) 1.6+/-0.7h; average concentration over the dosage interval (Cav) 711+/-269 microg/L; and area under the concentration-time curve (AUC) over 2 dosage intervals (24h) 17085+/-6464 microg x h/L. Corresponding values after administration of 300mg once daily were: Cmax 3461+/-854 microg/L; Cmin 146+/-87 microg/L; t1/2 7.9+/-3.4h; t(max) 2.2+/-1.3h; Cav 705+/-177 microg/L; and AUC over 1 dosage interval (24h) 16644+/-4150 microg x h/L. Statistical analysis showed a significant difference (p < 0.05) between the 2 schedules for Cmax and Cmin values, whereas no significant differences emerged for the other parameters. CONCLUSIONS Once daily lamivudine leads to a similar exposure in plasma as twice daily administration of the same total daily dose. Since once daily administration may result in improved compliance, these results provide the pharmacokinetic basis for using lamivudine in a once daily regimen. Randomised clinical studies are needed to confirm this pharmacokinetic finding.

Abstract
The pharmacokinetics of nelfinavir tablets (A) and an oral simplified nelfinavir suspension (B) were studied. Twelve healthy volunteers randomly received either five 250-mg nelfinavir tablets or a simplified oral suspension obtained from tablets dissolved in water (nelfinavir 1250 mg in 100 mL of water) in a single dose before being crossed over to the second treatment after a one-week washout period. Blood samples were drawn up to 24 h after drug administration. Nelfinavir concentrations in plasma were analyzed by a specific and validated reverse-phase high-performance liquid chromatography assay (HPLC) with UV detection, and pharmacokinetic values were determined. For the AUC(0-infinity) with means+/-SD of 31.71+/-7.85, 30.88+/-10.28 (microg/L) respectively for treatments B and A, the ratio (F(B/A)) was of 1.1 with a C.I. of 0.90-1.24. For Cmax with means+/-SD of 3.1+/-0.6 (treatment B) and 3.2+/-0.8 mg/mL (treatment A), the ratio was 1.0. with C.I. of 0.92-1.08. The two treatments evidenced no significant differences in AUC(0-inifnity) and Cmax values and the two-one sided t-test showed that the two preparations are bioequivalent. There was no significant difference in Tmax between the liquid and tablets. Nelfinavir suspension might be a option for treating HIV-infected patients with swallowing disturbances or compliance problems.
