Abstract
BACKGROUND Tumour-promoting inflammation is a "hallmark" of cancer and conventional epidemiological studies have reported links between various inflammatory markers and cancer risk. The causal nature of these relationships and, thus, the suitability of these markers as intervention targets for cancer prevention is unclear. METHODS We meta-analysed 6 genome-wide association studies of circulating inflammatory markers comprising 59,969 participants of European ancestry. We then used combined cis-Mendelian randomization and colocalisation analysis to evaluate the causal role of 66 circulating inflammatory markers in risk of 30 adult cancers in 338,294 cancer cases and up to 1,238,345 controls. Genetic instruments for inflammatory markers were constructed using genome-wide significant (P < 5.0 × 10-8) cis-acting SNPs (i.e., in or ±250 kb from the gene encoding the relevant protein) in weak linkage disequilibrium (LD, r2 < 0.10). Effect estimates were generated using inverse-variance weighted random-effects models and standard errors were inflated to account for weak LD between variants with reference to the 1000 Genomes Phase 3 CEU panel. A false discovery rate (FDR)-corrected P-value ("q-value") <0.05 was used as a threshold to define "strong evidence" to support associations and 0.05 ≤ q-value < 0.20 to define "suggestive evidence". A colocalisation posterior probability (PPH4) >70% was employed to indicate support for shared causal variants across inflammatory markers and cancer outcomes. Findings were replicated in the FinnGen study and then pooled using meta-analysis. FINDINGS We found strong evidence to support an association of genetically-proxied circulating pro-adrenomedullin concentrations with increased breast cancer risk (OR: 1.19, 95% CI: 1.10-1.29, q-value = 0.033, PPH4 = 84.3%) and suggestive evidence to support associations of interleukin-23 receptor concentrations with increased pancreatic cancer risk (OR: 1.42, 95% CI: 1.20-1.69, q-value = 0.055, PPH4 = 73.9%), prothrombin concentrations with decreased basal cell carcinoma risk (OR: 0.66, 95% CI: 0.53-0.81, q-value = 0.067, PPH4 = 81.8%), and interleukin-1 receptor-like 1 concentrations with decreased triple-negative breast cancer risk (OR: 0.92, 95% CI: 0.88-0.97, q-value = 0.15, PPH4 = 85.6%). These findings were replicated in pooled analyses with the FinnGen study. Though suggestive evidence was found to support an association of macrophage migration inhibitory factor concentrations with increased bladder cancer risk (OR: 2.46, 95% CI: 1.48-4.10, q-value = 0.072, PPH4 = 76.1%), this finding was not replicated when pooled with the FinnGen study. For 22 of 30 cancer outcomes examined, there was little evidence (q-value ≥0.20) that any of the 66 circulating inflammatory markers examined were associated with cancer risk. INTERPRETATION Our comprehensive joint Mendelian randomization and colocalisation analysis of the role of circulating inflammatory markers in cancer risk identified potential roles for 4 circulating inflammatory markers in risk of 4 site-specific cancers. Contrary to reports from some prior conventional epidemiological studies, we found little evidence of association of circulating inflammatory markers with the majority of site-specific cancers evaluated.

Abstract
During surveys in central Florida of the zombie-ant fungus Ophiocordyceps camponoti-floridani, which manipulates the behavior of the carpenter ant Camponotus floridanus, two distinct fungal morphotypes were discovered associated with and purportedly parasitic on O. camponoti-floridani. Based on a combination of unique morphology, ecology and phylogenetic placement, we discovered that these morphotypes comprise two novel lineages of fungi. Here, we propose two new genera, Niveomyces and Torrubiellomyces, each including a single species within the families Cordycipitaceae and Ophiocordycipitaceae, respectively. We generated de novo draft genomes for both new species and performed morphological and multi-loci phylogenetic analyses. The macromorphology and incidence of both new species, Niveomyces coronatus and Torrubiellomyces zombiae, suggest that these fungi are mycoparasites since their growth is observed exclusively on O. camponoti-floridani mycelium, stalks and ascomata, causing evident degradation of their fungal hosts. This work provides a starting point for more studies into fungal interactions between mycopathogens and entomopathogens, which have the potential to contribute towards efforts to battle the global rise of plant and animal mycoses.

Abstract
SummaryA disturbed methylation has been proposed as a mechanism via which homocysteine is associated with diseases like vascular disease, neural tube defects and mental disorders. Catechol- O-methyltransferase (COMT) is involved in the S-adenosylmethionine- dependent methylation of catecholamines and catecholestrogens and in this way contributes to homocysteine synthesis. COMT dysfunction has been related to schizophrenia and breast cancer. We hypothesized that COMT dysfunction by virtue of functional genetic polymorphisms may affect plasma total homocysteine (tHcy). Our primary objective was to study the association between common COMT polymorphisms and tHcy. Secondly, we evaluated these polymorphisms as a risk factor for recurrent venous thrombosis. We obtained genotype data from four polymorphisms in the COMT gene (rs2097603, rs4633, rs4680 [324G>A] and rs174699) from 401 populationbased controls. We performed haplotype analysis to investigate the association between common haplotypes and tHcy. In addition, we assessed the rs4680 variant as a genetic risk factor in a case-control study on recurrent venous thrombosis (n= 169). We identified a common haplotype that was significantly associated with tHcy levels. This effect was largely explained by the rs4680 variant, resulting in an increase in tHcy of 10.4% (95% CI 0.01 to 0.21, p=0.03) for 324AA compared with 324GG subjects. Interestingly, we found that the 324AA genotype was more common in venous thrombosis patients (OR 1.61 [95% CI 0.97 to 2.65], p=0.06) compared to control subjects. We show that the COMT rs4680 variant modulates tHcy, and might be associated with venous thrombosis risk as well.

Abstract
OBJECTIVE The frequent association of gout with metabolic syndrome and cardiovascular disease (CVD) suggests that it has a systemic component. Our objective was to study whether circulating proinflammatory cytokines are associated with comorbidities in gout patients. METHODS We studied 330 gout patients from 3 independent cohorts and compared them with 144 healthy individuals and 276 disease controls. We measured circulating levels of interleukin-8 (IL-8)/CXCL8, IL-1β, IL-6, IL-10, IL-12, and tumor necrosis factor, after which we performed proteome-wide analysis in a selection of samples to identify proteins that were possibly prognostic for the development of comorbidities. Replication analysis was performed specifically for myeloid-related protein 8 (MRP-8)/MRP-14 complex. RESULTS Compared to healthy controls and disease control patients, patients with gouty arthritis (n = 48) had significantly higher mean levels of CXCL8 (P < 0.001), while other cytokines were almost undetectable. Similarly, patients with intercritical gout showed high levels of CXCL8. CXCL8 was independently associated with diabetes mellitus in patients with intercritical gout (P < 0.0001). Proteome-wide analysis in gouty arthritis (n = 18) and intercritical gout (n = 39) revealed MRP-8 and MRP-14 as the proteins with the greatest differential expression between low and high levels of CXCL8 and also showed a positive correlation of MRP8/MRP14 complex with CXCL8 levels (R(2) = 0.49, P < 0.001). These findings were replicated in an independent cohort. The proteome of gout patients with high levels of CXCL8 was associated with diabetes mellitus (odds ratio 16.5 [95% confidence interval 2.8-96.6]) and CVD (odds ratio 3.9 [95% confidence interval 1.0-15.3]). CONCLUSION Circulating levels of CXCL8 are increased during both the acute and intercritical phases of gout, and they coincide with a specific circulating proteome that is associated with risk of diabetes mellitus and CVD. Further research focused on the roles of CXCL8 and MRP8/MRP14 complex in patients with gout is warranted.

Abstract
Extraversion is a relatively stable and heritable personality trait associated with numerous psychosocial, lifestyle and health outcomes. Despite its substantial heritability, no genetic variants have been detected in previous genome-wide association (GWA) studies, which may be due to relatively small sample sizes of those studies. Here, we report on a large meta-analysis of GWA studies for extraversion in 63,030 subjects in 29 cohorts. Extraversion item data from multiple personality inventories were harmonized across inventories and cohorts. No genome-wide significant associations were found at the single nucleotide polymorphism (SNP) level but there was one significant hit at the gene level for a long non-coding RNA site (LOC101928162). Genome-wide complex trait analysis in two large cohorts showed that the additive variance explained by common SNPs was not significantly different from zero, but polygenic risk scores, weighted using linkage information, significantly predicted extraversion scores in an independent cohort. These results show that extraversion is a highly polygenic personality trait, with an architecture possibly different from other complex human traits, including other personality traits. Future studies are required to further determine which genetic variants, by what modes of gene action, constitute the heritable nature of extraversion.

Abstract
IMPORTANCE Neuroticism is a pervasive risk factor for psychiatric conditions. It genetically overlaps with major depressive disorder (MDD) and is therefore an important phenotype for psychiatric genetics. The Genetics of Personality Consortium has created a resource for genome-wide association analyses of personality traits in more than 63,000 participants (including MDD cases). OBJECTIVES To identify genetic variants associated with neuroticism by performing a meta-analysis of genome-wide association results based on 1000 Genomes imputation; to evaluate whether common genetic variants as assessed by single-nucleotide polymorphisms (SNPs) explain variation in neuroticism by estimating SNP-based heritability; and to examine whether SNPs that predict neuroticism also predict MDD. DESIGN, SETTING, AND PARTICIPANTS Genome-wide association meta-analysis of 30 cohorts with genome-wide genotype, personality, and MDD data from the Genetics of Personality Consortium. The study included 63,661 participants from 29 discovery cohorts and 9786 participants from a replication cohort. Participants came from Europe, the United States, or Australia. Analyses were conducted between 2012 and 2014. MAIN OUTCOMES AND MEASURES Neuroticism scores harmonized across all 29 discovery cohorts by item response theory analysis, and clinical MDD case-control status in 2 of the cohorts. RESULTS A genome-wide significant SNP was found on 3p14 in MAGI1 (rs35855737; P = 9.26 × 10-9 in the discovery meta-analysis). This association was not replicated (P = .32), but the SNP was still genome-wide significant in the meta-analysis of all 30 cohorts (P = 2.38 × 10-8). Common genetic variants explain 15% of the variance in neuroticism. Polygenic scores based on the meta-analysis of neuroticism in 27 cohorts significantly predicted neuroticism (1.09 × 10-12 < P < .05) and MDD (4.02 × 10-9 < P < .05) in the 2 other cohorts. CONCLUSIONS AND RELEVANCE This study identifies a novel locus for neuroticism. The variant is located in a known gene that has been associated with bipolar disorder and schizophrenia in previous studies. In addition, the study shows that neuroticism is influenced by many genetic variants of small effect that are either common or tagged by common variants. These genetic variants also influence MDD. Future studies should confirm the role of the MAGI1 locus for neuroticism and further investigate the association of MAGI1 and the polygenic association to a range of other psychiatric disorders that are phenotypically correlated with neuroticism.

Abstract
Mega- or meta-analytic studies (e.g. genome-wide association studies) are increasingly used in behavior genetics. An issue in such studies is that phenotypes are often measured by different instruments across study cohorts, requiring harmonization of measures so that more powerful fixed effect meta-analyses can be employed. Within the Genetics of Personality Consortium, we demonstrate for two clinically relevant personality traits, Neuroticism and Extraversion, how Item-Response Theory (IRT) can be applied to map item data from different inventories to the same underlying constructs. Personality item data were analyzed in >160,000 individuals from 23 cohorts across Europe, USA and Australia in which Neuroticism and Extraversion were assessed by nine different personality inventories. Results showed that harmonization was very successful for most personality inventories and moderately successful for some. Neuroticism and Extraversion inventories were largely measurement invariant across cohorts, in particular when comparing cohorts from countries where the same language is spoken. The IRT-based scores for Neuroticism and Extraversion were heritable (48 and 49 %, respectively, based on a meta-analysis of six twin cohorts, total N = 29,496 and 29,501 twin pairs, respectively) with a significant part of the heritability due to non-additive genetic factors. For Extraversion, these genetic factors qualitatively differ across sexes. We showed that our IRT method can lead to a large increase in sample size and therefore statistical power. The IRT approach may be applied to any mega- or meta-analytic study in which item-based behavioral measures need to be harmonized.

Abstract
OBJECTIVE This study will investigate the reproducibility and influencing factors of exhaled breath temperature measured with the tidal breathing technique in asthmatic patients and healthy children. METHODS Exhaled breath temperature, fractional exhaled nitric oxide, and spirometry were assessed in 124 children (63 healthy and 61 asthmatic), aged 11.2 ± 2.5 year, M/F 73/51. A modified version of the American Thoracic Society questionnaire on the child's present and past respiratory history was obtained from parents. Parents were also asked to provide detailed information on their child's medication use during the previous 4 weeks. Ear temperature, ambient temperature, and relative-ambient humidity were also recorded. RESULTS Exhaled breath temperature measurements were highly reproducible; the second measurement was higher than the first measurement, consistent with a test-retest situation. In 13 subjects, between-session within-day reproducibility of exhaled breath temperature was still high. Exhaled breath temperature increased with age and relative-ambient humidity. Exhaled breath temperature was comparable in healthy and asthmatic children; when adjusted for potential confounders (i.e. ambient conditions and subject characteristics), thermal values of asthmatic patients exceeded those of the healthy children by 1.1 °C. Normalized exhaled breath temperature, by subtracting ambient temperature, was lower in asthmatic patients treated with inhaled corticosteroids than in those who were corticosteroid-naive. CONCLUSION Measurements of exhaled breath temperature are highly reproducible, yet influenced by several factors. Corrected values, i.e. normalized exhaled breath temperature, could help us to assess the effect of therapy with inhaled corticosteroids. More studies are needed to improve the usefulness of the exhaled breath temperature measured with the tidal breathing technique in children.

Abstract
Background Expansive remodelling is the process of compensatory arterial enlargement in response to atherosclerotic stimuli. The genetic determinants of this process are poorly characterized. Methods Genetic association analyses of inter-adventitial common carotid artery diameter (ICCAD) in the IMPROVE study (n = 3427) using the Illumina 200k Metabochip was performed. Single nucleotide polymorphisms (SNPs) that met array-wide significance were taken forward for analysis in three further studies (n = 5704), and tested for association with Abdominal Aortic Aneurysm (AAA). Results rs3768445 on Chromosome 1q24.3, in a cluster of protein coding genes (DNM3, PIGC, C1orf105) was associated with larger ICCAD in the IMPROVE study. For each copy of the rare allele carried, ICCAD was on average 0.13 mm greater (95% CI 0.08–0.18 mm, P = 8.2 × 10−8). A proxy SNP (rs4916251, R2 = 0.99) did not, however, show association with ICCAD in three follow-up studies (P for replication = 0.29). There was evidence of interaction between carotid intima-media thickness (CIMT) and rs4916251 on ICCAD in two of the cohorts studies suggesting that it plays a role in the remodelling response to atherosclerosis. In meta-analysis of 5 case–control studies pooling data from 5007 cases and 43,630 controls, rs4916251 was associated with presence of AAA 1.10, 95% CI 1.03–1.17, p = 2.8 × 10−3, I2 = 18.8, Q = 0.30). A proxy SNP, rs4916251 was also associated with increased expression of PIGC in aortic tissue, suggesting that this may the mechanism by which this locus affects vascular remodelling. Conclusions Common variation at 1q24.3 is associated with expansive vascular remodelling and risk of AAA. These findings support a hypothesis that pathways involved in systemic vascular remodelling play a role in AAA development.

Abstract
A solitary fibrous tumour (SFT) is a rare tumour that originates from the mesenchyme and arises mainly in the pleura. In this report, we present a rare case of a 77-year-old man with a SFT in the left nasal cavity. On CT and MRI, a large mass is seen in the left nasal cavity, extending to the choana. The mass was radically resected via functional endoscopic sinus surgery (FESS). Histological examination showed a fibroblastic mesenchymal tumour with a prominent hemangiopericytic vascular branching pattern that stained diffusely positive for the immunohistochemical markers CD34, Bcl-2, and CD99, which was compatible with the histopathological diagnosis of a SFT. Imaging and histological features are discussed, along with the reports in literature, clinical management, and follow-up of this pathology.

Abstract
The chromosome-type exchange aberrations induced by ionizing radiation during the G(0)/G(1) phase of the cell cycle are believed to be the result of illegitimate rejoining of chromosome breaks. From numerous studies using chromosome painting, it has emerged that even after a moderate dose of radiation, a substantial fraction of these exchanges is complex. Most of them are derived from the free interaction between the ends of three or more breaks. Other studies have demonstrated that chromosomes occupy distinct territories in the interphase nucleus. Since breaks that are in close proximity have an enhanced interaction probability, it seems likely that after ionizing radiation many of the interacting breaks will be present within one chromosome or chromosome arm. Unfortunately, the majority of these intrachanges remain undetected, even when sophisticated molecular cytogenetic detection methods (i.e. mFISH) are applied to paint all chromosome pairs in distinct colors. In the present paper, we evaluate the limitations of full-color painting for the detection of complex exchanges and the correct interpretations of break interactions.

Abstract
Preimplantation genetic diagnosis (PGD) requires the combined efforts of geneticists and workers in the field of reproductive medicine. This was studied on the basis of a questionnaire, sent to 35 members of the PGD Consortium of the European Society of Human Reproduction and Embryology (ESHRE). A reply was obtained from 20 centres. They represent the majority of activities in the field of PGD in the world. It is obvious that many of the activities (in vitro fertilisation, embryo culture and biopsy) take place in IVF units while others (counselling and diagnosis) are the responsibility of genetic diagnostic centres. The distances between both units vary considerably. In all but one centre sex determination is offered. Aneuploidy screening is offered in 13 out of 20 centres. PGD of translocations and other structural chromosome abnormalities is offered in all but one centre. The number of monogenic diseases offered varies considerably. In comparison to prenatal diagnosis PGD is more expensive. The majority of these costs are due to the IVF or ICSI procedure. The charges for PGD vary between about 600 euro and 4000 euro. In 16 out of 20 centres the parents to be must sign an informed consent form.

Abstract
PURPOSE To study the impact of radiation quality on the spectrum of chromosome exchange aberrations in human lymphocytes using chromosome arm-specific and telomeric probes. The analysis is focused on: (1) incomplete exchanges, (2) interstitial fragments, (3) interarm intrachanges and (4) the complexity of the aberration patterns. The present data after neutron exposure are compared with previously obtained data after X-irradiation. MATERIALS AND METHODS Isolated human lymphocytes from three donors were irradiated with 1 MeV fast neutrons (0.25, 0.5, 1.0, 1.5, 2.0 Gy). Analysis was performed on first post-irradiation metaphases with arm-specific probes for chromosome 1 in combination with a pan-centromeric probe, or with telomeric and centromeric PNA probes. RESULTS In comparison with X-rays, exposure to neutrons leads to: (1) similar frequencies of incomplete exchanges or terminal deletions, (2) a significantly higher induction of both inter- and intraarm intrachanges, (3) a higher proportion of complex aberrations, and (4) aberrations with a higher degree of complexity, i.e. derived from more chromosome breaks which interact more frequently in a non-reciprocal fashion. Essentially no dose dependence was found for the yield ratios between the various types of chromosomal aberrations. CONCLUSIONS Despite the reduced rejoining deficiency of DNA double-strand breaks induced by high-LET radiation, exposure to neutrons does not lead to enhanced levels of unrejoined chromosome breaks that can be observed as incomplete exchanges in cells that have reached mitosis. Proximity effects are more pronounced after densely ionizing radiation than after sparsely ionizing radiation. Clustered damage produced by neutron tracks results in a high proportion of complex aberrations and in non-reciprocal interactions of chromosome breaks. Most of the exchanges occur within one neutron track and little interaction seems to take place between the breaks formed in different tracks.

Abstract
The function of many transmembrane molecules can be altered by cleavage and subsequent release of their ectodomains. We have investigated ectodomain cleavage of the cell-cell adhesion and signal-transducing molecule E-cadherin. The E-cadherin ectodomain is constitutively shed from the surface of MCF-7 and MDCKts.srcC12 cells in culture. Release of the 80 kDa soluble E-cadherin fragment is stimulated by phorbol-12-myristate-13-acetate and is inhibited by overexpression of the tissue inhibitor of metalloproteinases-2. The metalloproteinases matrilysin and stromelysin-1 both cleave E-cadherin at the cell surface and release sE-CAD into the medium. The soluble E-cadherin fragment thus released inhibits E-cadherin functions in a paracrine way, as indicated by induction of invasion into collagen type I and inhibition of E-cadherin-dependent cell aggregation. Our results, therefore, suggest a novel mechanism by which metalloproteinases can influence invasion.

Abstract
The E-cadherin-catenin complex is important for the maintenance of epithelial architecture. We studied its expression in Crohn disease, ulcerative colitis, acute ileitis, and controls. Immunohistochemical stainings for E-cadherin, alpha-catenin, beta-catenin and gamma-catenin were performed. E-cadherin messenger RNA (mRNA) was detected using riboprobes. In active inflammation, there was up-regulation of the complex. In particular, epithelium adjacent to ulcers showed increased expression of protein and mRNA, but in ulcer-associated cell lineage, the intensity of staining was weak to negative. In focal inflammation, up-regulation was found in affected areas. Reparative epithelium growing over denuded areas showed weaker expression. Since structural or functional perturbation in any of the molecules of the E-cadherin-catenin complex results in loss of intercellular adhesion, the preexistent epithelium may benefit from up-regulation to try to maintain its normal architecture under inflammatory conditions. Reduced expression in reparative epithelium and ulcer-associated cell lineage could facilitate the motility of these cells.

Abstract
Between July 1993 and October 1997, 107 patients with 118 meningiomas were treated with Gamma Knife radiosurgery (GKRS). The most frequent site of tumor origin was the skull base (54%). The mean tumor diameter and volume were 2.5 cm and 9.4 cm3, respectively. The mean dose to the tumor periphery was 17 Gy, prescribed to a mean iso-dose of 47%. At a mean follow-up of 28 months, tumor control for basal and nonbasal meningiomas was 80%. Deteriorating peritumoral edema associated with symptoms was observed in 1 of 49 (2%) skull-base tumors and in 4 of 39 (10%) non-basal tumors, without associated tumor growth. (p=0.l5 and 0.234 respectively, z-test). Stereotactic radiosurgery can achieve acceptable tumor control with low morbidity in the treatment of most meningiomas. However, when the tumor is nonbasal, the potential morbidity from peritumoral edema should be recognized and other treatment options considered, such as adjuvant surgery, partial fractionated irradiation or stereotactic radiotherapy.

Abstract
OBJECTIVE Previously an upregulation of E-cadherin and its associated molecules alpha-catenin, beta-catenin and plakoglobin has been demonstrated in clinically overt inflammatory bowel disease (IBD). The aim of this study was to investigate the expression of the E-cadherin/catenin complex in subclinically inflamed bowel mucosa from spondyloarthropathy (SpA) patients. METHODS Ileal and colonic biopsy specimens from 19 SpA patients with subclinical inflammatory gut lesions and from seven controls were stained with monoclonal antibodies against E-cadherin, beta-catenin and plakoglobin and a polyclonal antibody against alpha-catenin. E-cadherin mRNA was detected using a riboprobe. Inflammation was histologically classified into acute, chronic active and chronic quiescent forms. RESULTS In acute and chronic active bowel inflammation of SpA patients, upregulation of the E-cadherin/catenin glycoprotein complex could be observed. Chronic lesions in a quiescent state did not show such an upregulation. Furthermore, chronic inflammation was associated with an increase in E-cadherin mRNA. CONCLUSIONS As some of the SpA patients with subclinical gut inflammation develop IBD, upregulation of the E-cadherin/catenin complex in inflamed bowel mucosa from SpA patients may point to early cellular changes in the development of IBD. However, at present it cannot be excluded that increased E-cadherin/catenin complex expression is a bystander phenomenon of active inflammation.

Abstract
PURPOSE To generate dose-response curves for X-ray-induced chromosomal aberrations analysed in human blood lymphocytes using telomeric and centromeric peptide nucleic acid (PNA) probes. MATERIALS AND METHODS Isolated human lymphocytes were X-irradiated with doses of 0, 1, 2, 3, 4 and 6 Gy. Aberrations were analysed in the first post-irradiation metaphases using telomeric and centromeric PNA probes. RESULTS Similar to the dose-response curves for the yield of dicentrics and centric rings, the dose-response curves for interstitial fragments and incomplete elements (derived from either terminal deletions or incomplete exchanges) follow a linear-quadratic function. Furthermore, it was estimated that 76% of excess acentric fragments originate from complete exchanges (interstitial deletions) and only 24% from incomplete exchanges or terminal deletions. CONCLUSIONS Interstitial fragments form a major class of radiation-induced chromosomal aberrations. They are induced about half as frequently as dicentrics over the whole dose range investigated. The comparable trend of the dose-response curve for the different aberrations, including incomplete elements, indicates that all detected aberrations are formed by a similar underlying mechanism. It also suggests that the ratio between non- or incomplete repair (leading to open ends of broken chromosomes) and incorrect repair (leading to exchange aberrations) is independent of dose.

Abstract
Cancer is a genetic disease. The unstable genome of cancer cells causes tumour progression through multiple alterations in suppressor and promoter genes, leading to loss of homeostatic and gain of oncogenic functions. Invasion is the critical step in the acquisition of malignancy. It implicates a continuous molecular conversation of the cancer cells with other cells and with the extracellular matrix in which adhesion molecules are crucial. One of these, E-cadherin, is discussed in the present review. E-cadherin is a transmembrane glycoprotein that forms a complex with cytoplasmic proteins, termed catenins because they link E-cadherin to the actin cytoskeleton. E-cadherin/catenin-mediated intercellular adhesion and communication is mainly homophylic homotypic. There is compelling evidence from experiments in vitro as well as in vivo to accept that the E-cadherin/catenin complex acts as an invasion suppressor. The mechanism of this action is not only through cell-cell adhesion but also through transduction of signals to the cell's motility system. In the replication error positive human colon cancer cell line HCT-8, the alpha E-catenin gene CTNNA1 is an invasion suppressor gene. Here, the transition from the non-invasive to the invasive state was prevented by introduction into the unstable non-invasive cells of either an extra CTNNA1 or a wild type hMSH6 mismatch repair gene. beta-catenin also participates at a complex which comprises the adenomatous polyposis cancer protein APC. In colorectal cancer, mutation of either APC or beta-catenin is oncogenic. Downregulation of the E-cadherin/catenin complex may occur in several ways amongst which are gene mutations, methylation of 5'CpG dinucleotides within the promotor region of E-cadherin, tyrosine phosphorylation of beta-catenin, cell surface expression of proteoglycans sterically hindering E-cadherin and proteolytic release of fragments from the extracellular part of E-cadherin. Upregulation of the E-cadherin/catenin complex has been realized with a series of agents, some of which can be used therapeutically. In most human gastrointestinal cancers the E-cadherin/catenin or related complexes are disturbed and this underscores their pivotal role in the progression of these tumours. Mutations of the E-cadherin gene, including germline mutations, occur in diffuse gastric carcinoma, CpG methylation around the promotor region of E-cadherin in hepatocellular carcinomas and mutations of the APC tumour suppressor gene or in the beta-catenin oncogene in most colorectal cancers. The literature agrees about the disturbance of immunohistochemical patterns of E-cadherin and catenin expression in gastrointestinal cancers. Conflicting opinions do, however, exist about the prognostic value of such immunohistochemical aberrations. We doubt that immunohistochemistry of E-cadherin or catenins add prognostic value to the already used histological grading systems. In our opinion the major benefit from understanding of the E-cadherin/catenin-mediated pathways of invasion will be the development of new anti-invasive treatment strategies.

Abstract
Patients with acoustic neuromas have several treatment options. The appropriate individual treatment decision and expected control rates and risks for the individual techniques have been outlined in several texts [1-4, 6-8]. This article describes radiosurgery toxicity in those patients with acoustic neuromas who have intracanalicular disease. 52 patients with 54 acoustic neuromas were treated between September 1993 and April 1997. 14 tumors were intracanalicular lesions, with a mean diameter <1 cm and volume <1 cm3. Dose to the periphery of the intracanalicular lesion extension ranged from 12-18 Gy (mean 16 Gy). The margin isodose was 40-60% (mean 47%). 32 isocenters were used to treat the 14 intracanalicular tumors (mean 2.3 isocenters per patient). At a mean follow-up of 18 months (range 1-39 months), 12/12 or 100% of the intracanalicular lesions demonstrated regression or no change in size on subsequent imaging. The following acute side effects were observed posttreatment in intracanalicular tumors: diminished hearing 14%, facial neuropathy 43%, trigeminal neuropathy 21%, balance disorder 14%, dizziness 7%, and headache 7%. Facial and trigeminal neuropathy, balance disorder, dizziness, vertigo and headaches were more common in patients with intracanalicular tumors than those with an extracanalicular extension. Although it has been suggested that small acoustic neuromas (i.e. <1 cm3) tolerate doses of 18 Gy with acceptable toxicity, when the lesion is located in the auditory canal a lesser dose may be warranted to minimize potential side effects. For now, our center has established a protocol that limits radiosurgical stereotactic intracanalicular peripheral doses to 12 Gy until further toxicity studies have been collected and reviewed.

Abstract
51 patients with medically refractory Parkinson's disease underwent stereotactic posteromedial pallidotomy between August 1993 and February 1997 for treatment of bradykinesia, rigidity, and L-DOPA-induced dyskinesias. In 29 patients, the pallidotomies were performed with the Leksell Gamma Knife and in 22 they were performed with the standard radiofrequency (RF) method. Clinical assessment as well as blinded ratings of Unified Parkinson's Disease Rating Scale (UPDRS) scores were carried out pre- and postoperatively. Mean follow-up time is 20.6 months (range 6-48) and all except 4 patients have been followed more than one year. 85 percent of patients with dyskinesias were relieved of symptoms, regardless of whether the pallidotomies were performed with the Gamma Knife or radiofrequency methods. About 2/3 of the patients in both Gamma Knife and radiofrequency groups showed improvements in bradykinesia and rigidity, although when considered as a group neither the Gamma Knife nor the radiofrequency group showed statistically significant improvements in UPDRS scores. One patient in the Gamma Knife group (3.4%) developed a homonymous hemianopsia 9 months following treatment and 5 patients (27.7%) in the radiofrequency group became transiently confused postoperatively. No other complications were seen. Gamma Knife pallidotomy is as effective as radiofrequency pallidotomy in controlling certain of the symptoms of Parkinson's disease. It may be the only practical technique available in certain patients, such as those who take anticoagulants, have bleeding diatheses or serious systemic medical illnesses. It is a viable option for other patients as well.

Abstract
alphaE-catenin, a cadherin-associated protein, is required for tight junction (TJ) organization, but its role is poorly understood. We transfected an alphaE-catenin-deficient colon carcinoma line with a series of alphaE-catenin mutant constructs. The results showed that the amino acid 326-509 domain of this catenin was required to organize TJs, and its COOH-terminal domain was not essential for this process. The 326-509 internal domain was found to bind vinculin. When an NH2-terminal alphaE-catenin fragment, which is by itself unable to organize the TJ, was fused with the vinculin tail, this chimeric molecule could induce TJ assembly in the alphaE-catenin-deficient cells. In vinculin-null F9 cells, their apical junctional organization was impaired, and this phenotype was rescued by reexpression of vinculin. These results indicate that the alphaE-catenin-vinculin interaction plays a role in the assembly of the apical junctional complex in epithelia.

Abstract
Frequencies of chromosomal aberrations were estimated in X-irradiated (0; 0.5; 1; 2; 3 and 4 Gy) human lymphocytes using arm-specific probes for chromosome 1 in combination with a pancentromeric probe in a triple colour FISH procedure. This allowed the construction of dose-response curves for both interchanges as well as interarm intrachanges. We found that 11.7-18.4% of aberrant chromosomes contained interarm intrachanges. Assuming a free interaction of randomly induced exchange breakpoints throughout the whole genome, interarm intrachanges occur about 8.7 times more frequently than expected. The close proximity of the two arms of a chromosome in the interphase nucleus appears to promote the formation of interarm intrachanges. Convincing evidence was obtained, by comparing the frequency of colour junctions that occur between 1p-1q and 1p-3q (the arms 1q and 3q are of similar size). With this approach, we observed 8.8 times more colour junctions between 1p-1q than between 1p-3q, illustrating the importance of proximity in the formation of chromosomal exchange aberrations. At doses higher than 2 Gy, a saturation of simple reciprocal aberrations, both for interchanges as well as for interarm intrachanges was observed. Furthermore, we found that symmetrical and asymmetrical simple interchanges as well as interarm intrachanges occur with equal frequencies in human chromosome 1.

Abstract
PURPOSE The detection of incomplete exchanges and interstitial fragments by fluorescence in situ hybridization using a telomeric peptide nucleic acid (PNA) probe. MATERIALS AND METHODS Isolated human lymphocytes were exposed in vitro to X-rays at a dose of 3 Gy. Aberrations were analysed in the first mitosis after irradiation using a telomeric PNA probe. RESULTS After an acute dose of 3 Gy, only about 16% of the cells contained a pair of incomplete chromosome elements with telomeric signals at only one terminal end. Acentric interstitial fragments, lacking telomeric signals, were observed with a frequency of 0.56 per cell, which was very similar to the dicentric frequency (0.61 per cell). CONCLUSIONS The low frequency of incompleteness suggests that most of the non-reciprocal interchanges observed using chromosome painting must originate from terminal exchanges rather than from incomplete exchanges. Furthermore, it was estimated that about 78% of excess acentric fragments originate from interstitial fragments and only 22% from terminal fragments.

Abstract
The radiation accident in focus here occurred in a section of Goiânia (Brazil) where more than a hundred individuals were contaminated with 137Cesium on September 1987. In order to estimate the absorbed radiation doses, initial frequencies of dicentrics and rings were determined in 129 victims [A.T. Ramalho, PhD Thesis, Subsidios a tecnica de dosimetria citogenetica gerados a partir da analise de resultados obtidos com o acidente radiologico de Goiânia, Universidade Federal do Rio de Janeiro, Rio de Janeiro, Brazil, 1992]. We have followed some of these victims cytogenetically over the years seeking for parameters that could be used as basis for retrospective radiation dosimetry. Our data on translocation frequencies obtained by fluorescence in situ hybridization (FISH) could be directly compared to the baseline frequencies of dicentrics available for those same victims. Our results provided valuable information on how precise these estimates are. The frequencies of translocations observed years after the radiation exposure were two to three times lower than the initial dicentrics frequencies, the differences being larger at higher doses (>1 Gy). The accuracy of such dose estimates might be increased by scoring sufficient amount of cells. However, factors such as the persistence of translocation carrying lymphocytes, translocation levels not proportional to chromosome size, and inter-individual variation reduce the precision of these estimates.

Abstract
Cancer is a chronic and progressive disease characterised by disturbances of growth, cellular differentiation and maintenance of tissue integrity. The latter phenomenon leads to invasion. The transition from the noninvasive towards the invasive stage of the disease is crucial because it transforms a benign and easily curable lesion into a malignant and therapy-resistant disease. Tumour progression is the result of a number of genetic alterations, initiated by a single mutation without immediate clinical manifestations and ending with a metastatic cascade. Activation of tumour-promoter genes (oncogenes), by mutation or overexpression, and inactivation of tumour-suppressor genes, by mutation or deletion, favour oncogenesis. Separate genes are implicated in distinct steps of the tumour progression. Defects in DNA-repair genes influence all steps. Metastasis is a multistep process of invasion. At each step invasion occurs within a micro-ecosystem in which a continuous molecular crosstalk takes place between the cancer cells and the host cells that participate at the establishment of the tumour. The cancer cells carry the genetic alterations and act as the founders of the micro-ecosystem. We shall discuss the invasion-suppressor function of the E-cadherin/catenin complex. Inactivation of one element of this complex may initiate invasion in an appropriate genetic background. Such inactivation may take place at various levels: mutation in coding sequences; hypermethylation of the promoter; mRNA instability; tyrosine phosphorylation; proteolysis; extracellular interactions.

Abstract
Frequencies of symmetrical and asymmetrical exchange aberrations induced by two inhibitors of topoisomerase II, namely, 4'-(9-acridinylamino) methanesulfon-m-anisidide (m-AMSA) and etoposide (VP16), were estimated in human peripheral blood lymphocytes. The aberrations were scored using conventional Giemsa staining and fluorescence in situ hybridization (FISH) techniques, using chromosome-specific DNA libraries. Stable aberrations (translocations) were detected using two cocktails of DNA libraries specific for three chromosomes, namely 1, 3 and X and 2, 4 and 8, representing approximately 40% of the whole human genome. The frequencies of dicentrics and translocations increased in a dose-dependent manner, however, m-AMSA was found to be a more potent inducer of chromosomal aberrations in comparison with VP16 (at concentrations at which comparable frequencies of aberrations were induced) by 20- to 30-fold. When corrected for DNA content of chromosomes in each cocktail, a higher frequency of translocations with the cocktail consisting of chromosomes 2, 4 and 8 in comparison with 1, 3 and X was evident. The genomic translocation frequency calculated from chromosome painting analysis for m-AMSA exceeded that estimated for dicentrics by approximately 2-fold. However, for VP16 almost equal frequencies of both types of chromosome exchange were found.

Abstract
Whole blood samples from two healthy donors were cultured in the presence of 5-bromo-2'-deoxyuridine (BrdU) for a total of 107 h following in vitro X-irradiation with a dose of 2 Gy. Starting from 35 h after culture initiation, every subsequent 12 h a sample was taken from each culture and grown in the presence of demecolcine for another 12 h. At each sampling time, the aberrations involving chromosomes 1 and 4 were analysed using dual-colour fluorescence in situ hybridization (FISH) with chromosome-specific DNA libraries. Following differential staining of sister chromatids, the analysed cells were identified to be either in their first, second or third etc. mitosis after irradiation. Cells within the same postirradiation division contained higher frequencies of aberrations when derived from later sampling times, indicating a delay in progression of aberrant cells to mitosis. In contrast, when the aberration frequencies are calculated by sampling time (i.e. independent of the cell cycle) minimal effect of sampling time could be seen. This observation held true for all types of chromosomal aberrations. Analysis of about 2250 first-division cells for each donor (derived from all sampling times) indicates a relative overrepresentation of chromosome 4 in the formation of exchange aberrations/colour junctions. Whereas dicentric frequencies for chromosomes 1 and 4 were close to the expected values based on the DNA content of these chromosomes, frequencies of reciprocal translocations showed a clear overinvolvement of chromosome 4. This resulted in a distinct difference in the reciprocal translocation to dicentric ratio, being 1.12 for chromosome 1 and 2.09 for chromosome 4. These results indicate a non-DNA-proportional distribution of radiation-induced chromosome rearrangements in cultured human lymphocytes.

Abstract
The alpha-catenin molecule links E-cadherin/ beta-catenin or E-cadherin/plakoglobin complexes to the actin cytoskeleton. We studied several invasive human colon carcinoma cell lines lacking alpha-catenin. They showed a solitary and rounded morphotype that correlated with increased invasiveness. These round cell variants acquired a more normal epithelial phenotype upon transfection with an alpha-catenin expression plasmid, but also upon treatment with the protein kinase C (PKC) activator 12-O-tetradecanoyl-phorbol-13-acetate (TPA). Video registrations showed that the cells started to establish elaborated intercellular junctions within 30 min after addition of TPA. Interestingly, this normalizing TPA effect was not associated with alpha-catenin induction. Classical and confocal immunofluorescence showed only minor TPA-induced changes in E-cadherin staining. In contrast, desmosomal and tight junctional proteins were dramatically rearranged, with a conversion from cytoplasmic clusters to obvious concentration at cell-cell contacts and exposition at the exterior cell surface. Electron microscopical observations revealed the TPA-induced appearance of typical desmosomal plaques. TPA-restored cell-cell adhesion was E-cadherin dependent as demonstrated by a blocking antibody in a cell aggregation assay. Addition of an antibody against the extracellular part of desmoglein-2 blocked the TPA effect, too. Remarkably, the combination of anti-E-cadherin and anti-desmoglein antibodies synergistically inhibited the TPA effect. Our studies show that it is possible to bypass the need for normal alpha-catenin expression to establish tight intercellular adhesion by epithelial cells. Apparently, the underlying mechanism comprises upregulation of desmosomes and tight junctions by activation of the PKC signaling pathway, whereas E-cadherin remains essential for basic cell-cell adhesion, even in the absence of alpha-catenin.

Abstract
PURPOSE To determine factors associated with survival differences in patients treated with radiosurgery for glioma. METHODS AND MATERIALS We analyzed 189 patients treated with Gamma Knife radiosurgery for primary or recurrent glioma World Health Organization (WHO) Grades 1-4. RESULTS CONCLUSION The median minimum tumor dose was 16 Gy (8-30 Gy) and the median tumor volume was 5.9 cc (1.3-52 cc). Brachytherapy selection criteria were satisfied in 65% of patients. Median follow-up of all surviving patients was 65 weeks after radiosurgery. For primary glioblastoma patients, median survival from the date of pathologic diagnosis was 86 weeks if brachytherapy criteria were satisfied and 40 weeks if they were not (p = 0.01), indicating that selection factors strongly influence survival. Multivariate analysis showed that increased survival was associated with five variables: lower pathologic grade, younger age, increased Karnofsky performance status (KPS), smaller tumor volume, and unifocal tumor. Survival was not found to be significantly related to radiosurgical technical parameters (dose, number of isocenters, prescription isodose percent, inhomogeneity) or extent of preradiosurgery surgery. We developed a hazard ratio model that is independent of the technical details of radiosurgery and applied it to reported radiosurgery and brachytherapy series, demonstrating a significant correlation between survival and hazard ratio. CONCLUSIONS Survival after radiosurgery for glioma is strongly related to five selection variables. Much of the variation in survival reported in previous series can be attributed to differences in distributions of these variables. These variables should be considered in selecting patients for radiosurgery and in the design of future studies.
