Abstract
Molecular markers of dedifferentiation of dysfunctional liver sinusoidal endothelial cells (LSEC) have not been fully elucidated. We aimed at deciphering the molecular profile of dysfunctional LSEC in different pathological scenarios. Flow cytometry was used to sort CD11b-/CD32b+ and CD11b-/CD32b- LSEC from three rat models of liver disease (bile duct ligation-BDL; inhaled carbon tetrachloride-CCl4; and high fat glucose/fructose diet-HFGFD). A full proteomic profile was performed applying nano-scale liquid chromatography tandem mass spectrometry (nLC-MS) and analyzed with PEAKS software. The percentage of CD32b- LSEC varied across groups, suggesting different capillarization processes. Both CD32+ and CD32b- LSEC from models are different from control LSEC, but differently expressed proteins in CD32b- LSEC are significantly higher. Heatmaps evidenced specific protein expression patterns for each model. Analysis of biological significance comparing dysfunctional CD32b- LSEC with specialized CD32b+ LSEC from controls showed central similarities represented by 45 common down-regulated proteins involved in the suppression of the endocytic machinery and 63 common up-regulated proteins associated with the actin-dependent cytoskeleton reorganization. In summary; substantial differences but also similarities in dysfunctional LSEC from the three most common models of liver disease were found, supporting the idea that LSEC may harbor different protein expression profiles according to the etiology or disease stage.

Abstract
BACKGROUND & AIMS Donation after brain death (DBD) grafts are associated with reduced graft quality and function post liver transplantation (LT). We aimed to elucidate i) the impact of FGF15 levels on DBD grafts; ii) whether this impact resulted from altered intestinal FXR-FGF15; iii) whether administration of FGF15 to donors after brain death could confer a benefit on graft function post LT; and iv) whether FGF15 affects bile acid (BA) accumulation. METHODS Steatotic and non-steatotic grafts from DBD donors and donors without brain death were transplanted in rats. FGF15 was administered alone or combined with either a BA (cholic acid) or a YAP inhibitor. RESULTS Brain death induced intestinal damage and downregulation of FXR. The resulting reduced intestinal FGF15 was associated with low hepatic FGF15 levels, liver damage and regenerative failure. Hepatic FGFR4-Klb - the receptor for FGF15 - was downregulated whereas CYP7A1 was overexpressed, resulting in BA accumulation. FGF15 administration to DBD donors increased hepatic FGFR4-Klb, reduced CYP7A1 and normalized BA levels. The benefit of FGF15 on liver damage was reversed by cholic acid, whereas its positive effect on regeneration was maintained. YAP signaling in DBD donors was activated after FGF15 treatment. When a YAP inhibitor was administered, the benefits of FGF15 on regeneration were abolished, whereas its positive effect on hepatic damage remained. Neither the Hippo-YAP-BA nor the BA-IQGAP1-YAP axis was involved in the benefits of FGF15. CONCLUSION Alterations in the gut-liver axis contribute to the reduced quality of DBD grafts and the associated pathophysiology of LT. FGF15 pre-treatment in DBD donors protected against damage and promoted cell proliferation. LAY SUMMARY After brain death, potential liver donors have reduced intestinal FXR, which is associated with reduced intestinal, circulatory and hepatic levels of FGF15. A similar reduction in the cell-surface receptor complex Fgfr4/Klb is observed, whereas CYP7A1 is overexpressed; together, these molecular events result in the dangerous accumulation of bile acids, leading to damage and regenerative failure in brain dead donor grafts. Herein, we demonstrate that when such donors receive appropriate doses of FGF15, CYP7A1 levels and hepatic bile acid toxicity are reduced, and liver regeneration is promoted.

Abstract
Background Desmoplastic melanoma (DM) is a rare subtype of spindle cell malignant melanoma characterized by frequent local recurrences and hematogenous spread, but without molecular classification. The aim of the study was to investigate in a DM series the incidence of relevant gene alterations in cancer, the programmed death-ligand 1 (PD-L1) expression status and the association with clinicopathological features and melanoma progression. Methods A total of 38 patients were included. Clinical follow-up and the histopathological features of all cases were retrospectively collected. PD-L1 expression by immunohistochemistry (IHC) and BRAF genomic alterations by real-time PCR were determined in 34 samples. Additionally, a molecular analysis by next-generation sequencing was performed in 25 DMs. Results Tumors occurred predominantly in men (76%) and in the head and neck region (50%). Most tumors were pure DMs (66%), containing less than 10% of conventional melanoma. Overall, 48% of our cohort harbored TP53 mutations, most of them showing a molecular signature associated with ultraviolet (UV)-oncogenesis, and 29%, BRAF mutations. A positive correlation between TP53 with depth of invasion (P=0.005) and presence of elastosis (P=0.002) was found. High-expression of PD-L1 in tumor cells was observed in 38% of cases and correlated with depth of tumoral infiltration (P=0.003), TP53 (P=0.016), PD-1 (P<0.001) and tumor-infiltrating lymphocytes (TILS) (P<0.001). PD-L1 expression in immune cells correlated with PD-1 (P=0.006), tumoral PD-L1 expression (P=0.029) and TP53 mutation (P=0.002). Survival correlated with depth of invasion (P=0.003), stage of tumors (P=0.015), positive sentinel lymph node (P=0.004), lymph node metastasis (P=0.024) and distant metastasis (P<0.001). Conclusions Our results suggest that progressed DMs with deep tumoral infiltration frequently harbor TP53 mutations, PD-L1 expression and present a high inflammatory response, probably related to adaptive immune resistance in this tumor-type.

Abstract
BACKGROUND AND AIMS Hepatic epithelioid hemangioendothelioma is an ultra-rare hepatic vascular tumor, diagnosed more frequently in females. The knowledge about this tumor derives mainly from small case series with sub-optimal treatment outcomes. The aim of this study is to identify the clinical and radiological issues helpful to develop an international prospective registry. METHODS We conducted an international multicentric and retrospective study of patients with hepatic hemangioendothelioma. The clinical, pathological and radiological images collected during follow-up were reviewed. Central radiological revision was performed and 3 patterns of contrast were defined. RESULTS Between 1994 and 2016, 27 patients with hepatic hemangioendothelioma were identified in three institutions but the final diagnosis was hepatic angiosarcoma in one. The majority were females, median age was 38.7-years and 17 patients were asymptomatic at diagnosis. No patient had Two out of ten (20%) patients had surgical specimens with positive macro-vascular invasion and 50% had extrahepatic disease, and the most frequent pattern was the progressive-central-contrast-uptake. After a median follow-up of 6.7-years, the 5- and 10-year survival rates are 91.5% and 51.9%, respectively. CONCLUSIONS This multicentric study shows the heterogeneous profile of patients with hepatic hemangioendothelioma, reflecting the need to establish a reference network in order to better characterize these patients and ultimately develop a personalized treatment strategy.

Abstract
BACKGROUND Leishmaniasis is an emerging infectious disease. Due to human migration and tourism, visceral leishmaniasis may become more common in non-endemic areas. In the Mediterranean basin, visceral leishmaniasis typically occurs in rural regions. CASE PRESENTATION We present an unusual urban case of acute liver failure due to visceral leishmaniasis, following a prolonged fever of unknown origin. After obtaining negative results from the bone marrow aspirate, we performed a liver biopsy that elucidated the diagnosis. The liver involvement in visceral leishmaniasis may appear as chronic granulomatous hepatitis. However diffuse hepatitis process, a necro-inflammatory pattern, without forming granulomas were observed in the liver biopsy specimens in this case. Intracytoplasmic Leishmania amastigotes were observed in the liver biopsy specimens and a polymerase chain reaction confirmed the diagnosis. Only five pathological confirmed cases of acute hepatitis due to visceral leishmaniasis have been described so far, just two in adults and both from Barcelona. A revision of the literature is performed. CONCLUSIONS Acute hepatitis is an uncommon debut of visceral leishmaniasis in immunocompetent patients. Furthermore there are only few cases in the literature that describe the histopathological changes that we found in this patient. In conclusion, in case of acute hepatitis leading to liver failure, leishmaniasis should be considered a differential diagnosis (even in non-endemic countries and without clear epidemiological exposure) and liver biopsy can elucidate the diagnosis.

Abstract
OBJECTIVE Based on some of the recommendations of the SEMICYUC working groups, we developed a checklist and applied it in 2 periods, analyzing their behavior as a tool for improving safety. DESIGN A comparative pre- and post-intervention longitudinal study was carried out. SETTING The Intensive Care Unit (ICU) of a 400-bed university hospital. PATIENTS Random cases series in 2 periods separated by 6 months. INTERVENTIONS We developed a checklist with 24 selected indicators that were randomly applied to 50 patients. Verification was conducted by a professional not related to care (prompter). We analyzed the results and compliance index and carried out corrective measures with training. With 6 months of preparation, we again applied the random checklist to 50 patients (post-intervention period) and compared the compliance indexes between the two timepoints. RESULTS There were no differences in demographic characteristics or evolution between the periods. The compliance index at baseline was 0.86±0.12 versus 0.91±0.52 in the post-intervention period (P=.023). An acceptable compliance index was obtained with the 24 indicators, though at baseline the compliance index was<0.85 for 5 recommendations. These detected non-compliances were worked upon through training in the second phase of the study. The post-intervention checklist evidenced improvement in compliance with the recommendations. CONCLUSIONS The checklist used to assess compliance with a selection of recommendations of the SEMICYUC applied and moderated by a prompter was seen to be a useful instrument allowing us to identify points for improvement in the management of Intensive Care Unit patients, increasing the quality and safety of care.

Abstract
A sequential multiprobe fluorescence in situ hybridization technique was developed to study the 13, 18, 21, X and Y chromatid segregation in human lymphocytes anaphases cultures without antimitotic treatment. This method was used to know if exist any different chromosomes segregation in lymphocytes from Down syndrome patients and compared it with controls. The results show that the prevalent sequence of centromere separation was X, 13, 21, Y and 18 in Down syndrome patients and Y, 13, X, 21 and 18 in controls. Chromatid segregation in early anaphase was asynchronic for all chromosome pairs studied. Late anaphase showed a frequency of non-disjunction of 4.5% in the controls, affecting only chromosomes 18 and Y; in the Down syndrome patients, the frequency was higher (20.3%) and affected all chromosomes studied. This technique could be applicated to know the incidence of non disjunction in couples with repetitive abortions or in cases with different aneuploidies in the offspring.

Abstract
Pericentric inversion of chromosome 19 appears to be a rare abnormality with only a few families reported. As far as we are aware, none of them were ascertained because of a recombinant individual. We describe the first identified case due to an affected patient, with duplication deficiency for chromosome 19 arising from a maternal inversion confirmed by FISH and CGH. His features included prenatal growth retardation, microcephaly, dysmorphic facies, congenital heart defect, hypoplasia of corpus callosum and psychomotor delay. The identification of recombinant individuals contribute to calculate a precise risk for inv (19) carriers and to provide a more accurate genetic counselling.

Abstract
10531 Background: Letrozole (L) is more active than tamoxifen in early stage ER[+] breast cancer both as adjuvant (BIG-98 trial) or neoadjuvant (LET-024) therapy. However, complete pathological remissions to neoadjuvant endocrine therapy are anecdotal (<5%), there are no new prognostic indicators with clinical implications. Methods: We have review our series of postmenopausal patients with stage II-III breast cancer ER/PgR[+] breast cancer treated in our institution with L as neoadjuvant therapy. All patients had completed 4 months of therapy (in the absence of PD), and had measurable clinical (or radiological) disease. An independent statistical analysis was conducted for disease free (DFS) and distant disease free survival (DDFS). Results: From IV/99 to XII/04, 107 patients fulfill the criteria. Median age 76 years (range 64 to 92); median tumour size 35 mm (range 25 to 100); cT2 75 (70%), cT3/4 32 (30%); cN[-] 83 (78%). The ORR (PR + CR) at 4 months was 63% (7 CR and 60 PR), 4 patients had PD as best response (4%) and 36 a SD (34%). Surgery was done in 63 patients (59%), including all non-responders. Only 2 patients received adjuvant CT. With a median follow-up of 32 month (range 8 to 66), 12 patients had relapsed (9 distant). The 3 years DFS and DDFS were 84% and 90% respectively. In univaried analysis: cN (p < 0.02), cT3/4 (p < 0.02), and clinical response at 4 months (CR) (p = 0.003) were related to DFS; and HER2 (p < 0.05), cN (p < 0.003), and CR (p = 0.007) with DDFS. Other factors like cT, HR-levels, or surgery were not significant. Multivariate analysis showed that only OR and cN remained independently predictive both for DFS and DDFS. Conclusions: Clinical response to neoadjuvant letrozole therapy is an independent predictor of distant disease free survival and could be of value to recommend or deny more aggressive therapies in addition to endocrine therapy.

Abstract
In humans, the presence of supernumerary chromosomes is an unusual phenomenon, which is often associated with developmental abnormalities and malformations. In contrast to most animal and plant species, the extensive knowledge of the human genome and the ample set of molecular and cytogenetic tools available have permitted to ascertain not only that most human supernumerary chromosomes (HSCs) derive from the A chromosome set, but also the specific A chromosome from which most of them arose. These extra chromosomes are classified into six types on the basis of morphology and size. There are both heterochromatic and euchromatic HSCs, the latter being more detrimental. Most are mitotically stable, except some producing individual mosaicism. No information is available on the HSC transmission rate since extensive familial studies are not usually performed generally because of death of the relatives or lack of cooperation. The main B chromosome property failing in HSCs seems to be their population spread as polymorphisms, since most HSCs seem to correspond to extra A chromosomes or centric fragments spontaneously arisen in the analysed individual or one of his/her parents. However, we cannot rule out at this moment, that more intensive studies on population distribution and frequency of those HSCs most closely resembling B chromosomes (i.e. those heterochromatic and thus less detrimental) would reveal possible HSCs polymorphisms. Although HSCs cannot be considered B chromosomes, some of them might be a source for future B chromosomes. The best candidates would be heterochromatic HSCs, which might manage to drive in either sex. To ascertain this possibility, research on inheritance and population studies would be very helpful in combination with the powerful cytogenetic and molecular tools available for our species.

Abstract
The quantitative fluorescent PCR (QF-PCR) assay, introduced during the last few years, allows prenatal diagnoses of common chromosome aneuploidies in a few hours after sampling. We report the first assessment of QF-PCR performed on a large cohort of 18,000 consecutive clinical specimens analysed in two different Centres. All samples were analysed by QF-PCR using several selected STR markers together with amelogenin and, occasionally, SRY for fetal sexing. Results were compared with those obtained by conventional cytogenetic analysis. In 17,129 tests, normal fetuses were detected by QF-PCR. No false positives were observed. All 732 cases of trisomy 21, 18, 13, triploidies, double trisomies as well as all but one fetuses with X and Y aneuploidies were correctly diagnosed. Chromosome mosaicism could also be suspected in several samples. In some cases of in vitro culture failures, QF-PCR was the only evidence of fetal X, Y, 21, 18 and 13 chromosome complement. QF-PCR proved to be efficient and reliable in detecting major numerical chromosome disorders. The main advantages of the molecular assay are its very low cost, speed and automation enabling a single operator to perform up to 40 assays per day. QF-PCR relieves anxiety of most parents within 24 h from sampling and accelerates therapeutic interventions in the case of an abnormal result. In countries where large scale conventional cytogenetics is hampered by its high cost and lack of technical expertise, QF-PCR may be used as the only prenatal diagnostic test.

Abstract
We describe three cases in which we used fluorescence in situ hybridization (FISH), polymerase chain reaction (PCR) and comparative genomic hybridization (CGH) to characterize Y chromosome structural anomalies, unidentifiable by conventional G-banding. Case 1 was a 46,X,+mar karyotype; FISH analysis revealed an entire marker chromosome highlighted after hybridization with the Y chromosome painting probe. The PCR study showed the presence of Y chromosome markers AMG and SY620 and the absence of SY143, SY254 and SY147. CGH results confirmed the loss of Yq11.2-qter. These results indicated the presence of a deletion: del(Y)(q11.2). Case 2 was a 45,X [14]/46,XY[86] karyotype with a very small Y chromosome. The PCR study showed the presence of Y chromosome markers SY620 and AMG, and the absence of SY143, SY254 and SY147. CGH results showed gain of Yq11.2-pter and loss of Yq11.2-q12. These results show the presence of a Yp isodicentric: idic(Y)(q11.2). Case 3 was a 45,X,inv(9)(p11q12)[30]/46,X,idic(Y)(p11.3?),inv(9)(p11q12)[70] karyotype. The FISH signal covered all the abnormal Y chromosome using a Y chromosome paint. The PCR study showed the presence of Y chromosome markers AMG, SY620, SY143, SY254 and SY147. CGH only showed gain of Yq11.2-qter. These results support the presence of an unbalanced (Y;Y) translocation. Our results show that the combined use of molecular and classical cytogenetic methods in clinical diagnosis may allow a better delineation of the chromosome regions implicated in specific clinical disorders.

Abstract
This report describes the fourth case of heritable 18p monosomy, which was ascertained by prenatal diagnosis. Cytogenetic analysis of amniotic fluid cells by G-banding showed an apparently distal 18p chromosome deletion and a derivative X chromosome resulting from a translocation between the X and Y chromosomes. Analysis of peripheral blood lymphocytes from the parents by G-banding revealed the same chromosome 18 deletion in the mother, who did not have the X/Y translocation. Comparative genomic hybridization (CGH) studies confirmed the loss of chromosome region 18p11.3-pter previously detected, and eliminated the presence of unbalanced reorganizations of other chromosome regions. No subtle translocation was detected by fluorescence in situ hybridization (FISH) studies using whole chromosome specific painting probes. This is a new report of a heritable 18p monosomy. Although in our case the mother had several minor congenital malformations, the loss of 18p11.3 band was not associated with any obvious phenotypic alteration in the fetus.

Abstract
The clinical application of quantitative fluorescent polymerase chain reaction (QF-PCR) for rapid prenatal detection of chromosome aneuploidies has been limited in most studies to the detection of autosomal trisomies. Recently it has been shown that a newly identified highly polymorphic marker, termed X22, which maps to the Xq/Yq pseudoautosomal region of the sex chromosomes, used together with the X-linked short tandem repeat (STR) HPRT, allows the accurate detection of gonosome aneuploidies. We have developed a rapid assay, which includes these STR markers together with a sequence of the amelogenin region of the sex chromosomes and selected highly polymorphic autosomal STR. Two more X chromosome markers, as yet not used in previous QF-PCR applications, were also included in the assay. The molecular test was then used in a clinical trial on 551 uncultured amniotic fluid samples, allowing the assessment of copy number for chromosomes X, Y and 21 in 100% of cases. In the course of this study, two fetuses with Turner's syndrome and one with Klinefelter's syndrome were identified along with 17 autosomal trisomies. The assay proved to be so efficient and reliable that in most aneuploidy cases, in which ultrasound findings were in agreement with the molecular result, therapeutical interventions were possible without waiting for the result of cytogenetic analysis.

Abstract
Rapid prenatal diagnoses of major chromosome aneuploidies have been achieved successfully using quantitative fluoresent PCR (QF-PCR) assays and small tandem repeat (STR) markers. Here we report the results of evaluating the use of previously untested X-linked STRs, (DXS6803) and (DXS6809), together with modified amelogenin (AMXY) sequences and the X22 marker that maps in the pseudoautosomal region PAR2 on the long arm of the X and Y chromosomes. These markers will allow prenatal diagnoses of sex chromosome aneuploidies such as 45,X (pure Turner Syndrome), 47,XXY and 47,XYY, while assessing the sex of the fetuses. Data are also presented concerning the difficulties associated with the evaluation of the frequencies of the various types of sub-populations of cells in amniotic fluid samples collected from fetuses with sex chromosome mosaicism. The results of evaluating the use of new markers for the rapid diagnosis of aneuploidies affecting chromosomes 21,18 and 13 are also presented. Three chromosome 21 specific STRs have been found to produce trisomic triallelic or diallelic patterns from all amniotic samples retrieved from fetuses with Down Syndrome. Since all samples tested were amplified and no false positive or negative results were observed, the present results confirm the diagnostic value of QF-PCR for the prenatal detection of major numerical chromosome disorders.

Abstract
We have investigated the preferential bending of some chromosome sites in blood cultures from normal and chromosomally abnormal subjects. A total of 2,262 centromeric and 2,718 non-centromeric bends were recorded, and 69 non-centromeric sites were found not to bend at random. 15q11-13 bending was found to be the most frequent non-random autosomal bend. Bends on chromosomes may be remnants of a folded chromosome state in the nucleus, and may facilitate the preferential involvement of some chromosomal bands in structural reorganizations such as the isoacentric fragments, or contribute to the high frequency of interstitial deletions and isodicentric inversion duplications involving the 15q11-13 region.

Abstract
We used comparative genomic hybridization to analyze 10 primary tumor samples from patients with transitional cell carcinoma of the renal pelvis. The most frequent loss was located at 9q, that is, in 50% of the tumors. Gains of DNA sequences were most frequently observed in chromosome regions 1q21 approximately q23, 2p23 approximately p25, 8q21.1 approximately q22 and in the whole chromosome 20. High level amplifications at 1q21 approximately q25, 6p22 approximately p23, 8q21 approximately q22, 8q22 approximately q24.1, 11q13, and 12q14 approximately q21 were detected. Most of these regions have previously been reported to be involved in transitional cell carcinoma of the bladder, thus confirming the importance of an increasing number of chromosome imbalances in the development and progression of this type of tumors.

Abstract
We report the use of comparative genomic hybridization (CGH) to define the extra chromosome region present in two de novo partial trisomies 15q25-qter and Xp21-pter, which could not be clarified by conventional G-banding. Investigation with fluorescence in situ hybridization (FISH) revealed that the partial trisomy corresponded to an unbalanced translocation between Y and 15 chromosomes in 1 patient and an unbalanced X/X reorganization in the other patient. The combination of classical karyotyping, CGH, and FISH is useful for the identification and characterization of partial trisomies in clinical diagnostic laboratories, in order to delineate the chromosome regions implicated in specific clinical disorders.

Abstract
A sequential fluorescence in situ hybridization (FISH) technique is described. This method allows the detection of up to eighteen chromosome pairs in consecutive hybridizations (8 steps) on the same metaphase using centromeric, whole chromosome painting, and single copy DNA probes with different fluorochromes. The technique may be used with diagnostic purposes in cases with poor cytogenetic material.

Abstract
A complex familial chromosome translocation has been ascertained by combining classical cytogenetics and CISS (chromosomal in situ suppression). Cytogenetic analysis of a chorionic villus sample with G banding showed a 47,XX,-2, +der(2)t(2;22),+der(22)t(2;22) karyotype. Analysis of peripheral blood lymphocytes from the parents by G banding and CISS showed a more complex translocation in the father: 46,XY,-2,-11,-22, +der(2) t(2;11)(q13;q23), +der(11) t(11;22) (q23;q11.2), +der(22) t(2;22) (q13;q11.2). Definitive analysis of cultured amniotic fluid cells showed a double partial trisomy of chromosomes 11 and 22. The couple decided to continue the pregnancy. The fetal karyotype was confirmed at birth. Clinical abnormalities present in our patient were typical of an unbalanced 11;22 translocation. Our findings confirm that chromosome painting techniques allow a better characterisation of complex chromosome rearrangements which may be difficult to detect in G banded karyotypes.

Abstract
BACKGROUND Investigation of an outbreak of bacillar dysentery of possible transmission by water produced by Shigella boydii. METHODS The strains were isolated in the stools and studies of identification, serotyping, susceptibility to antibiotics and plasmid profile were carried out according to standard methods. The epidemiological investigation was carried out retrospectively. RESULTS 51 strains were isolated from 48 patients. All were identified as S. boydii serotype 4. The pattern of susceptibility was variable, all of them showed resistance to ampicillin, tetracycline and chloramphenicol. The plasmid profile was homogeneous. Of the 41 patients who completed the questionnaire all were living in the same town or nearby localities. CONCLUSIONS The serotype 4 of S. boydii, infrequent in Spain, the homogeneous plasmid profile and the relationship between time and place of the cases, suggest that we find ourselves faced with an outbreak epidemiologically relationed. The localisation of the cases and the network of the drinking water supply represented on the plan of the town, support the hypothesis of the origin of hte outbreak as being in the lack of chlorination of one of the tanks of the network of supply.

Abstract
BACKGROUND Strains of Escherichia coli are frequently plasmid carriers. In this species, resistance to beta-lactam antibiotics is almost always conditioned by the production of enzymes coded by plasmidic genes. The present is a study of the plasmids of 44 ampicillin-sensitive strains and 134 ampicillin-resistant (ampS and ampR). The possibility that the number and size of the plasmids are different and that this data may be added to the information to be considered in these two groups of strains is suggested. METHODS The 178 strains selected had been isolated from human products. Sensitivity to ampicillin was studied by diffusion and was confirmed with the study of MIC (Mueller-Hinton agar, innoculum: 5 x 10 CFU). The plasmid type beta-lactamases were identified by analytical isoelectrofocus. Characterization of the plasmids was performed according to a variant of the Birnboim and Doly alkaline lysis technique. RESULTS Among the ampR and ampS strains no plasmid were observed in 9 (6.72%) and 11 (25%) respectively. The mean number of plasmids was 2.53 and 1.57, ranging between 0-10 and 0-5. The number of strains with plasmids larger than, or equal to, 38 Kb was 113 and 27 respectively. The largest plasmids observed in the ampS strains were of 99 Kb and in the ampR of 109 Kb. A total of 3.73% of the ampR strains presented plasmids larger than 99 Kb and 8.20% more than 5 plasmids. CONCLUSIONS No plasmids, presence of up to five and sizes smaller than or equal to 99 Kb were observed in strains of ampS and ampR. The presence of more than five and/or plasmids larger than or equal to 100 Kb was observed in 11.94% of the ampR.

Abstract
Most Salmonella typhi isolated in Spain are susceptible to antibiotics commonly used in its treatment as chloramphenicol, ampicillin and cotrimoxazole. Three multiresistant strains have been isolated from different patients the last two years. Two phage type M1, biotype xylose tetrationate + strains were isolated from blood of two patients in Bembibre (León). One phage type E1a biotype xylose + tetrationate reductase + strain was isolated from blood and faeces of one patient in Barcelona. All strains harboured a 79 Mdal plasmid responsible for multiresistance, chloramphenicol acetyl transferase production and conjugative.

Abstract
In a study of chromosome fragility carried out under folate and thymidine deficiency conditions, we observed a seven- to ninefold increase of the incidence of premature centromere divisions (PCDs) affecting all chromosomes. This early separation of centromeres is clearly a culture effect and distinct from PCD and centromere splitting (CS), which imply a defect in the centromere of one or more chromosomes.

Abstract
We have carried out cytogenetic studies, using the G-banding technique, in peripheral blood lymphocytes of 10 patients affected by breast carcinoma. The frequency of aberrant metaphases (7.36%) is significantly different from that of our laboratory controls (3.76% of aberrant metaphases) but not from that detected in patients suffering from bladder cancer (10.64%) and Hodgkin's disease (11.03%), two conditions that have previously been described as chromosomally unstable. Our results suggest that breast carcinoma patients show a degree of chromosomal instability that could be related to a predisposition to neoplastic disease.

Abstract
The spontaneous decondensation of constitutive heterochromatic regions of chromosomes 1, 9, 16, and Y has been observed in 46.6 per cent of chorionic villus samples. This type of decondensation is occasionally observed in amniotic fluid cells (9 per cent) and has never been found in fetal lymphocytes. The phenomenon is similar to that described in spermatogonial metaphases, in primary and secondary spermatocytes and in human sperm chromosomes, although decondensation of the heterochromatin of chromosome 15 has never been recorded in chorionic villus samples.

Abstract
Human fragile sites are only very rarely expressed spontaneously. In this paper we report the presence of non-random spontaneous chromosome lesions (CL) in chorionic villus samples and their coincidence with fragile site (FS) bands. The average number of CL was about 9% both in RPMI-1640 and in Chang media. To determine any possible influence of external factors other than culture media, the results were grouped according to age of gestation. No differences were observed among the different groups. A total of 101 chromosome lesions could be precisely identified by sequential Leishman Staining/Wright G-banding; 76.2% of them coincided with FS-bands. The most affected region was at 1q12-1q21.1 (15.8% of total CL); other FS with a clustering of breakpoints in our study were 1p36, 1q44, 2q37, 3p24, 3q27, 10q22 and 16q23. These results suggest that spontaneous expression of some FS could be a characteristic of embryonic tissues.

Abstract
The frequency and types of chromosome aberrations induced by ionizing radiation in cancer patients were evaluated in 24 cases studied just before and immediately after radiotherapy. The incidence of aberrant metaphases prior to treatment was 9.98% and increased significantly after treatment to 32.8%. The frequency of chromosome aberrations before radiotherapy was, with the exception of the cases of breast cancer and seminoma, significantly higher than that in our laboratory controls. A comparison of chromosome abnormalities observed before and after treatment indicated that dicentric translocations, rings, and reciprocal translocations increased by a factor of 23, 13, and 11, respectively, after radiotherapy. Ionizing radiation produces more asymmetrical than symmetrical chromosome aberrations and more two-break than one-break anomalies.

Abstract
Telomere association of chromosomes of a phenotypically and mentally normal individual was detected in 11.7% of metaphases cultured in RPMI-1640 with aphidicolin. No preferential involvement of any chromosome pair was detected. In two other individuals the frequency of telomere associations was much lower (1.9% and 0.7% respectively) under the same culture conditions. In the first individual the high number of telomere associations in cultures with aphidicolin along with the presence of telomere association (2.4%) in cultures with F.10 medium alone could reflect a constitutional telomere anomaly that is more often expressed in the presence of aphidicolin.

Abstract
To evaluate the reliability of the quantitative extrapolation of the long-term effect of cancer therapies from somatic cells to germ cells, we compared the frequency of chromosome abnormalities in 303 lymphocytes from four individuals treated with radio- and/or chemotherapy 5-18 years earlier with the frequency in 422 spermatozoa from the same individuals. The mean frequency of structurally abnormal complements was much higher in germ cells than in somatic cells (P = 2.08 x 10(-6)). The fact that spermatogenic cells share cytoplasm is suggested as a possible factor in the increased viability of germ cells with chromosome aberrations. In addition, in spermatozoa the incidence of structural chromosome abnormalities was much higher in treated individuals than in controls (P less than 0.00060), while in lymphocytes no statistically significant differences could be observed. This observation and the apparent lack of relationship between individual frequencies in the two kinds of cells suggest that the long-term effect of anti-tumor treatments on germ cells cannot be extrapolated from the analysis of somatic cells.

Abstract
A total of 660 breakpoints were identified in the chromosome aberrations detected in lymphocytes from cancer patients after radiotherapy. The results show that chromosomes 1, 3, and 7 were significantly more affected than other chromosomes by ionizing radiation in vivo. Chromosome arms 1p, 1q, 7q, and 11p were also significantly more affected. Some bands also showed a special sensitivity to radiation, and band 1q32 was the most affected. This band is proposed as a "hot point" for the clastogenic effect of ionizing radiation. A significant clustering of breakpoints in G bands was also found, especially at the telomeres, as previously described by other authors. Clustering of breakpoints was also observed in bands where fragile sites, protooncogenes, breakpoints involved in chromosomal cancer rearrangements, and breakpoints involved in chromosomal evolution of the Hominoidea are located.

Abstract
Recently, it has been suggested that an association exists between breakpoints involved in constitutional rearrangements and fragile sites; however, statistical analyses of this relationship are controversial. We have analyzed 1200 breakpoint from different constitutional rearrangements, 1522 breakpoints with respect to their recurrence and 217 breakpoints from sperm chromosomes as reported by several authors. The coincidence between breakpoints and fragile sites was 35.3%, 43.6% and 41.9% respectively. The statistical significance of these coincidences depends on whether factors such as the relative length of the bands or the recurrence of the rearrangements are taken into account.
