Abstract
BACKGROUND Targeted therapy (TT) with encorafenib and cetuximab is the current standard for patients with BRAFV600E-mutated metastatic colorectal cancer (mCRC) who received one or more prior systemic treatments. However, the median progression-free survival (mPFS) is ∼4 months, and little is known about the possibility of administering subsequent therapies, their efficacy, and clinicopathological determinants of outcome. METHODS A real-world dataset including patients with BRAFV600E-mutated mCRC treated with TT at 21 Italian centers was retrospectively interrogated. We assessed treatments after progression, attrition rates, and outcomes. RESULTS Of the 179 patients included, 85 (47%), 32 (18%), and 7 (4%) received one, two, or three lines of treatment after TT, respectively. Those receiving TT in the second line were more likely to receive at least one subsequent therapy (53%), as compared with those treated with TT in the third line or beyond (30%; P < 0.0001), and achieved longer postprogression survival (PPS), also in a multivariate model (P = 0.0001). Among 62 patients with proficient mismatch repair/microsatellite stable (pMMR/MSS) tumors receiving one or more lines of treatment after second-line TT, combinatory chemotherapy ± anti-vascular endothelial growth factor (anti-VEGF) was associated with longer PFS and PPS as compared with trifluridine-tipiracil or regorafenib (mPFS: 2.6 versus 2.0 months, P = 0.07; PPS: 6.5 versus 4.4 months, P = 0.04). CONCLUSIONS Our real-world data suggest that TT should be initiated as soon as possible after the failure of first-line treatment in BRAFV600E-mutated mCRC. Among patients with pMMR/MSS tumors, combinatory chemotherapy ± anti-VEGF appears the preferred treatment choice after TT failure.

Abstract
Background Encorafenib plus cetuximab with or without binimetinib showed increased objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) compared with chemotherapy plus anti-EGFR in previously treated patients with BRAF V600E-mutated (mut) metastatic colorectal cancer (mCRC). Although no formal comparison was planned, addition of binimetinib to encorafenib plus cetuximab did not provide significant efficacy advantage. Patients and methods This real-life study was aimed at evaluating safety, activity, and efficacy of encorafenib plus cetuximab with or without binimetinib in patients with BRAF V600E-mut mCRC treated at 21 Italian centers within a nominal use program launched in May 2019. Results Out of 133 patients included, 97 (73%) received encorafenib plus cetuximab (targeted doublet) and 36 (27%) the same therapy plus binimetinib (targeted triplet). Most patients had Eastern Cooperative Group Performance Status (ECOG-PS) of 0 or 1 (86%), right-sided primary tumor (69%), and synchronous disease (66%). Twenty (15%) tumors were DNA mismatch repair deficiency (dMMR)/microsatellite instability (MSI)-high. As many as 44 (34%) patients had received two or more prior lines of therapy, 122 (92%) were previously exposed to oxaliplatin, and 109 (82%) to anti-vascular endothelial growth factor (anti-VEGF). Most frequent adverse events were asthenia (62%) and anti-EGFR-related skin rash (52%). Any grade nausea (P = 0.03), vomiting (P = 0.04), and diarrhea (P = 0.07) were more frequent with the triplet therapy, while melanocytic nevi were less common (P = 0.06). Overall, ORR and disease control rate (DCR) were 23% and 69%, respectively, with numerically higher rates in the triplet group (ORR 31% versus 17%, P = 0.12; DCR 78% versus 65%, P = 0.23). Median PFS and OS were 4.5 and 7.2 months, respectively. Worse ECOG-PS, peritoneal metastases, and more than one prior treatment were independent poor prognostic factors for PFS and OS. Clonality of BRAF mutation measured as adjusted mutant allele fraction in tumor tissue was not associated with clinical outcome. Conclusions Our real-life data are consistent with those from the BEACON trial in terms of safety, activity, and efficacy. Patients in good general condition and not heavily pretreated are those more likely to derive benefit from the targeted treatment. Encorafenib plus cetuximab ± binimetinib is safe and effective for BRAF V600E mut mCRC even in the real-world setting. Median OS is slightly shorter than in the BEACON trial, probably due to less selected patients in real life. Patients deriving more benefit from targeted therapy are likely those in good general conditions and not heavily pretreated. BRAF adjusted MAF is worth further investigation to better characterize the genomic heterogeneity of BRAF V600E mut mCRC.

Abstract
The typical vertebrate centromeres contain long stretches of highly repeated DNA sequences (satellite DNA). We previously demonstrated that the karyotypes of the species belonging to the genus Equus are characterized by the presence of satellite-free and satellite-based centromeres and represent a unique biological model for the study of centromere organization and behavior. Using horse primary fibroblasts cultured in vitro, we compared the segregation fidelity of chromosome 11, whose centromere is satellite-free, with that of chromosome 13, which has similar size and a centromere containing long stretches of satellite DNA. The mitotic stability of the two chromosomes was compared under normal conditions and under mitotic stress induced by the spindle inhibitor, nocodazole. Two independent molecular-cytogenetic approaches were used—the interphase aneuploidy analysis and the cytokinesis-block micronucleus assay. Both assays were coupled to fluorescence in situ hybridization with chromosome specific probes in order to identify chromosome 11 and chromosome 13, respectively. In addition, we tested if the lack of centromeric satellite DNA affected chromatid cohesion under normal and stress conditions. We demonstrated that, in our system, the segregation fidelity of a chromosome is not influenced by the presence of long stretches of tandem repeats at its centromere. To our knowledge, the present study is the first analysis of the mitotic behavior of a natural satellite-free centromere.

Abstract
Centromeres are the sites of kinetochore assembly and spindle fiber attachment and consist of protein-DNA complexes in which the DNA component is typically characterized by the presence of extended arrays of tandem repeats called satellite DNA. Here, we describe the isolation and characterization of a 137-bp-long new satellite DNA sequence from the horse genome (EC137), which is also present, even if less abundant, in the domestic donkey, the Grevy's zebra and the Burchelli's zebra. We investigated the chromosomal distribution of the EC137 sequence in these 4 species. Moreover, we analyzed its architectural organization by high-resolution FISH. The position of this sequence with respect to the primary constriction and in relation to the 2 major horse satellite tandem repeats (37 cen and 2PI) on horse chromosomes suggests that the new centromeric equine satellite is an accessory DNA element, presumably contributing to the organization of pericentromeric chromatin. FISH on combed DNA fibers reveals that the EC137 satellite is organized in relatively short stretches (2-8 kb) which are strictly intermingled within 37 cen or 2PI arrays. This arrangement suggests that interchanges between satellite families are a frequent occurrence in the horse genome.

Abstract
AIMS The aims of the study are to evaluate, in the Italian context, the presence and clinical features of early prodromal symptoms before the psychotic onset and, most of all, the duration of the period between the first onset of any psychiatric symptom and the psychotic onset (Duration of Untreated Illness). MATERIALS AND METHODS The study was carried out on a sample of 296 inpatients with a diagnosis of "non-affective psychosis" enrolled in "Villa dei Fiori" inpatients Clinic in Rome. The retrospective analysis was developed using clinical records and clinical interview with patients and their parents. The evaluation of the psychotic onset and of DUI was assessed with the PANSS (Positive and Negative Symptoms Scale). RESULTS The mean DUI is 4.7 ± 4.4 years. We found a connection between DUI and early symptoms of psycosis: depressive symptoms (4.9; DS=5.0) were most frequently observed, followed by anxiety symptoms (5.1; DS=4.8), eating disorders (5.7; DS=3.0); obsessive symptoms (4.5; DS=3.6); social withdrawal (5.9; DS=4.9); psychotic like symptoms (2.6; DS=1.3). DUI resulted lower in psychotic like symptoms than in the depressive ones. CONCLUSION In Italy DUI turn out to be much longer than in other Country where do exists specialized services for early intervention. For this reason seem to be necessary to explore the opportunity to develop also in Italy specialized services for adolescents and young adults at risk and at their psychotic onset.

Abstract
AIMS The association between pharmacological treatment and psychotherapy is frequent. However doesn't exist any agreement or guide-line about the management of this combined therapy. Therefore we considered useful to evaluate which were the most frequent way of management of the combined therapy in a sample of 120 psychiatrists. MATERIALS AND METHODS A 10-items questionnaire finalized to explore the management way of the combined therapy was administered to a sample of 120 psychiatrists. A descriptive analysis of the data was made and the association between different variables was explored. The statistical analysis was performed using SPSS 13.0. RESULTS 35% of the sample work as a private practitioner, 19.17% is involved in public health (CMHT'S). More than 50% of the sample consider the combined therapy as a effective. In the public field the combined treatment turn out to be the most utilized, opposite than in private practice. 75% of the sample manage alone the combined therapy, while 25% work in team with a colleague. 85% of the pharmacotherapy is utilized in psychosis with positive symptoms, followed by the mood disorder with psychotic symptoms. Neuroleptics are the most frequently prescribed drug. CONCLUSIONS The combined therapy seems to be useful when coherently with the psychotherapy theory model. The pharmacological treatment should be utilized when strictly necessary and, if is possible, the combined therapy should be managed by one psychiatrist.

Abstract
Two transchromosomic mouse embryonic stem (ES) sublines (ESMClox1.5 and ESMClox2.1) containing a human minichromosome (MC) were established from a sample of hybrid colonies isolated in fusion experiments between a normal diploid mouse ES line and a Chinese hamster ovary line carrying the MC. DNA cytometric and chromosome analyses of ESMClox1.5 and ESMClox2.1 indicated a mouse chromosome complement with a heteroploid constitution in a subtetraploid range; the karyotypes showed various degrees of polysomy for different chromosomes. A single copy of the MC was found in the majority of cells in all the isolated hybrid colonies and was stably maintained in the established sublines for more than 100 cell generations either with or without the selective agent. No significant differences from the ES parental cells were observed in growth characteristics of the transchromosomic ES sublines. ESMClox1.5 cells were unable to grow in soft agar; when cultured in hanging drops, they formed embryoid bodies, and when inoculated in nude mice, they produced teratomas. They were able to express the early development markers Oct4 and Nanog, as demonstrated by reverse transcription-polymerase chain reaction assay. All these features are in common with the ES parental line. Further research using the transchromosomic ES sublines described here may allow gene expression studies on transferred human minichromosomes and could shed light on the relationships among ploidy, pluripotency, cell transformation, and tumorigenesis. Disclosure of potential conflicts of interest is found at the end of this article.

Abstract
Human chromosome 9 is involved in a number of recurrent structural rearrangements; moreover, its pericentromeric region exhibits a remarkable evolutionary plasticity. In this study we present the molecular characterization of a constitutional rearrangement, involving the 9p21.1q13 region, which led to the formation of a supernumerary marker chromosome (SMC). We defined the sequence of the breakpoints and identified a new set of duplicons on human chromosome 9, named LCR9s (chromosome 9 low-copy repeats). Two of these duplicons were shown to be involved in a somatic exchange leading to the formation of the SMC. High-resolution FISH coupled to database search demonstrated that a total number of 35 LCR9 paralogs are present in the human genome. These newly described chromosome 9 duplicons have features that may be crucial in driving structural chromosome rearrangements in germinal and somatic cells.

Abstract
Tigger elements are human DNA transposons homologous to the pogo element of Drosophila melanogaster. They contain an open reading frame for a transposase very similar to the major mammalian centromere protein CENP-B. We found in the horse genome a DNA element ( Ecatig3) sharing 88% homology with human Tigger3. The presence of Tigger elements in the horse genome confirms previous data that date these elements before the divergence between Perissodactyla and Primates (80-90 Myr ago). Copy number evaluation indicates that the horse element is much more abundant than its human counterpart. Southern blot analysis demonstrates that Ecatig3 elements are extremely homogeneous; this may indicate that the evolution of this DNA transposon has been driven by some kind of selection and has not been neutral.

Abstract
The generation in vitro of mammalian artificial chromosomes, in view of the possibility of developing new technologies for gene therapy, is still an ambitious goal. Mammalian artificial chromosomes, to be used as cloning and expression vectors, have been constructed either by de novo synthesis or by reduction of pre-existing chromosomes. In the work here reported, we introduced a loxP sequence into the pericentromeric region of a chromosome 9-derived X-ray-reduced minichromosome, with the purpose of generating a human chromosome vector (HCV). The modified accessory chromosome is linear and mitotically stable, has lost at least 1400 kb of alpha satellite DNA and normally binds CENP-B, CENP-C and CENP-E. The efficiency of gene targeting via loxP mediated homologous recombination was tested using the histone H2B-Green Fluorescent Protein chimaeric gene as a reporter. The frequency of site-specific insertion of the exogenous sequence was found to be about 50% and to occur in a controlled way with regard to the number of copies. The expression level of the fusion protein was stable over prolonged time in culture.

Abstract
A human supernumerary minichromosome (MC), previously identified as a derivative of chromosome 9, has been introduced into Chinese hamster ovary (CHO) cells by means of cell fusion. A hybrid clone containing the MC as the only free human chromosome was isolated. A selectable marker gene (neo) inserted into a yeast artificial chromosome (YAC) has been successfully targeted to the MC centromeric DNA via co-transfection with chromosome-9-specific alpha satellite DNA. In situ hybridization and Southern blotting experiments demonstrated that the intact neo gene was integrated into the MC centromeric DNA. Studies on the clonal distribution and on the stability of the MC either in the presence or in the absence of the selective agent have been carried out. The MC is susceptible to further manipulations and may thus represent a model for the construction of a large-capacity vector for somatic gene therapy.

Abstract
A mutation assay in cultured mammalian cells was developed based on direct analysis of minisatellite DNA. Chinese hamster cells (V79) were mutagenized with nitrosoguanidine and independent colonies were isolated and expanded. DNA fingerprints were then obtained after digestion with HinfI or HaeIII and hybridization with 33.15 and 33.6 probes (Jeffreys et al., 1985). 12 colonies from untreated cells were also analyzed. Digestion with HaeIII and hybridization with 33.15 probe detected the highest frequency of induced variants. The results suggest that minisatellite sequences are hypermutable sites that can be used to monitor the mutagenic effect of chemical agents. We have also analyzed the DNA fingerprints of 17 independent Chinese hamster (CHO) cell lines carrying amplification of the CAD gene. The DNA fingerprint analysis showed a variation in minisatellite regions in 3 lines while no variation was observed in independent colonies from the CHO parental cell line. The results suggest that these sequences may be hot spots for recombination during gene amplification.

Abstract
An X;X chromosomal translocation was ascertained by conventional cytogenetic analysis in a phenotypically normal woman with secondary amenorrhea. In situ hybridization was performed with previously mapped X-specific DNA sequences to study the rearrangement at the molecular level. The results allowed us to demonstrate that the subject is monosomic for the distal region of the short arm of the X and trisomic for the distal region of the long arm.

Abstract
A case of ileo-colic invagination caused by lipoma of the last loop of the small intestine is reported. The anatomo-clinical features of this neoformation are illustrated and stress is laid on certain special aspects: the rarity (about 300 cases have been described in the literature), the lack of symptomatology and its insidious development without pathognomonic sign up to the occurrence of occlusive episodes. The surgery carried out and the result obtained are reported.
