Abstract
PURPOSE Widespread application of next-generation sequencing, combined with data exchange platforms, has provided molecular diagnoses for countless families. To maximize diagnostic yield, we implemented an unbiased semi-automated genematching algorithm based on genotype and phenotype matching. METHODS Rare homozygous variants identified in 2 or more affected individuals, but not in healthy individuals, were extracted from our local database of ∼12,000 exomes. Phenotype similarity scores (PSS), based on human phenotype ontology terms, were assigned to each pair of individuals matched at the genotype level using HPOsim. RESULTS 33,792 genotype-matched pairs were discovered, representing variants in 7567 unique genes. There was an enrichment of PSS ≥0.1 among pathogenic/likely pathogenic variant-level pairs (94.3% in pathogenic/likely pathogenic variant-level matches vs 34.75% in all matches). We highlighted founder or region-specific variants as an internal positive control and proceeded to identify candidate disease genes. Variant-level matches were particularly helpful in cases involving inframe indels and splice region variants beyond the canonical splice sites, which may otherwise have been disregarded, allowing for detection of candidate disease genes, such as KAT2A, RPAIN, and LAMP3. CONCLUSION Semi-automated genotype matching combined with PSS is a powerful tool to resolve variants of uncertain significance and to identify candidate disease genes.

Abstract
The PP2A-B55 phosphatase regulates a plethora of signaling pathways throughout eukaryotes. How PP2A-B55 selects its substrates presents a severe knowledge gap. By integrating AlphaFold modelling with comprehensive high resolution mutational scanning, we show that α-helices in substrates bind B55 through an evolutionary conserved mechanism. Despite a large diversity in sequence and composition, these α-helices share key amino acid determinants that engage discrete hydrophobic and electrostatic patches. Using deep learning protein design, we generate a specific and potent competitive peptide inhibitor of PP2A-B55 substrate interactions. With this inhibitor, we uncover that PP2A-B55 regulates the nuclear exosome targeting complex by binding to an α-helical recruitment module in RBM7. Collectively, our findings provide a framework for the understanding and interrogation of PP2A-B55 in health and disease.

Abstract
Recently, a transcriptome-based consensus molecular subtype (CMS) classification of colorectal cancer (CRC) has been established, which may ultimately help to individualize CRC therapy. However, the lack of animal models that faithfully recapitulate the different molecular subtypes impedes adequate preclinical testing of stratified therapeutic concepts. Here, we demonstrate that constitutive AKT activation in intestinal epithelial cells markedly enhances tumor invasion and metastasis in Trp53ΔIEC mice (Trp53ΔIECAktE17K) upon challenge with the carcinogen azoxymethane. Gene-expression profiling indicates that Trp53ΔIECAktE17K tumors resemble the human mesenchymal colorectal cancer subtype (CMS4), which is characterized by the poorest survival rate among the four CMSs. Trp53ΔIECAktE17K tumor cells are characterized by Notch3 up-regulation, and treatment of Trp53ΔIECAktE17K mice with a NOTCH3-inhibiting antibody reduces invasion and metastasis. In CRC patients, NOTCH3 expression correlates positively with tumor grading and the presence of lymph node as well as distant metastases and is specifically up-regulated in CMS4 tumors. Therefore, we suggest NOTCH3 as a putative target for advanced CMS4 CRC patients.

Abstract
BACKGROUND Metabolic syndrome and its individual components lead to wide-ranging consequences, many of which affect the central nervous system. In this study, we compared the [18F]FDG regional brain metabolic pattern of participants with type 2 diabetes mellitus (T2DM) and non-DM obese individuals. METHODS In our prospective study, 51 patients with controlled T2DM (ages 50.6 ± 8.0 years) and 45 non-DM obese participants (ages 52.0 ± 9.6 years) were enrolled. Glucose levels measured before PET/CT examination (pre-PET glucose) as well as laboratory parameters assessing glucose and lipid status were determined. NeuroQ application (NeuroQTM 3.6, Syntermed, Philips) was used to evaluate regional brain metabolic differences. [18F]FDG PET/CT (AnyScan PC, Mediso) scans, estimating brain metabolism, were transformed to MNI152 brain map after T1 registration and used for SPM-based group comparison of brain metabolism corrected for pre-PET glucose, and correlation analysis with laboratory parameters. RESULTS NeuroQ analysis did not reveal significant regional metabolic defects in either group. Voxel-based group comparison revealed significantly (PFWE<0.05) decreased metabolism in the region of the precuneus and in the right superior frontal gyrus (rSFG) in the diabetic group as compared to the obese patients. Data analysis corrected for pre-PET glucose level showed a hypometabolic difference only in the rSFG in T2DM. Voxel-based correlation analysis showed significant negative correlation of the metabolism in the following brain regions with pre-PET glucose in diabetes: precuneus, left posterior orbital gyrus, right calcarine cortex and right orbital part of inferior frontal gyrus; whilst in the obese group only the right rolandic (pericentral) operculum proved to be sensitive to pre-PET glucose level. CONCLUSIONS To our knowledge, this is the first study to perform pre-PET glucose level corrected comparative analysis of brain metabolism in T2DM and obesity. We also examined the pre-PET glucose level dependency of regional cerebral metabolism in the two groups separately. Large-scale future studies are warranted to perform further correlation analysis with the aim of determining the effects of metabolic disturbances on brain metabolism.

Abstract
Sentinel lymph node biopsy (SLNB) is a standard procedure for regional lymph node staging and still has the most important prognostic value for the outcome of patients with thin melanoma. In addition to ulceration, SLNB had to be considered even for a single mitotic figure in thin (<1 mm) melanoma according to AJCC7th guideline, therefore, a retrospective review was conducted involving 403 pT1 melanoma patients. Among them, 152 patients suffered from pT1b ulcerated or mitotic rate ≥ 1/ mm2 melanomas according to the AJCC7th staging system. SLNB was performed in 78 cases, of which nine (11.5%) showed SLN positivity. From them, interestingly, we found a relatively high positive sentinel rate (6/78-8%) in the case of thin primary melanomas ˂0.8 mm. Moreover, the presence of regression increased the probability of sentinel positivity by 5.796 fold. After reassessing pT stage based on the new AJCC8th, 37 pT1b cases were reordered into pT1a category. There was no significant relation between other characteristics examined (age, gender, Breslow, Clark level, and mitosis index) and sentinel node positivity. Based on our data, we suggest that mitotic rate alone is not a sufficiently powerful predictor of SLN status in thin melanomas. If strict histopathological definition criteria are applied, regression might be an additional adverse feature that aids in identifying T1 patients most likely to be SLN-positive. After reassessing of pT1b cases according to AJCC8th regression proved to be independent prognostic factor on sentinel lymph node positivity. Our results propose that sentinel lymph node biopsy might also be considered at patients with regressive thin (˂0.8 mm) melanomas.

Abstract
Background:Previous studies suggested that male sex may be associated with a greater rate of decline in FVC in patients with SSc-ILD. In the SENSCIS trial, nintedanib reduced the rate of FVC decline over 52 weeks vs placebo.Objectives:Analyse the rate of decline in FVC and the efficacy and safety of nintedanib in the SENSCIS trial in subgroups by sex.Methods:Patients with SSc-ILD with first non-Raynaud symptom <7 years before screening and ≥10% fibrosis of the lungs on HRCT were randomised to nintedanib or placebo. We analysed the rate of decline in FVC (mL/year) and adverse events over 52 weeks in male and female patients.Results:Of 576 patients, 433 (75.2%) were female. Compared with males, the female subgroup included a smaller proportion of White patients (64.7% vs 74.8%), a smaller proportion on mycophenolate at baseline (46.9% vs 53.1%), a greater proportion of ATA positive patients (63.3% vs 53.1%), and had a lower mean weight at baseline (66.6 vs 79.1 kg). FVC % predicted (72.8% vs 71.7%) and mRSS (11.2 vs 10.8) were similar in females and males. The adjusted annual rate of decline in FVC in the placebo group was numerically greater in male than female patients (-126.8 [SE 29.0] vs -82.0 [16.2] mL/year). The estimated effect of nintedanib vs placebo on reducing the rate of decline in FVC was numerically more pronounced in males than females (difference: 58.6 [95% CI -18.0, 135.1] vs 34.6 [-9.3, 78.4] mL/year), but the interaction p-value did not indicate heterogeneity in the treatment effect between subgroups (p=0.59). Among nintedanib-treated patients, diarrhoea was reported in similar proportions of females and males (74.7% vs 79.1%); nausea, vomiting and liver test abnormalities were reported in greater proportions of females vs males (35.3% vs 19.4%, 28.1% vs 13.4%, and 15.4% vs 9.0%), while serious adverse events were more frequent in males (32.8% vs 21.3%). In the nintedanib and placebo groups, respectively, adverse events leading to treatment discontinuation were reported in 16.7% and 8.5% of females and 13.4% and 9.2% of males.Conclusion:In the SENSCIS trial in patients with SSc-ILD, the annual rate of decline in FVC in the placebo group was numerically greater in male than female patients. The rate of FVC decline was lower with nintedanib than placebo both in males and females. The safety profile of nintedanib was similar between males and females.Disclosure of Interests:Elizabeth Volkmann Grant/research support from: Forbius, Corbus Pharmaceuticals, Consultant of: Boehringer Ingelheim, Forbius, Speakers bureau: Boehringer Ingelheim, Serena Vettori Consultant of: Boehringer Ingelheim, John Varga Grant/research support from: John Varga is awaiting grants from Boehringer Ingelheim and has received grants from Bristol-Myers Squibb, Pfizer, Takeda, and TeneoBio, Consultant of: John Varga has acted as a consultant for Boehringer Ingelheim, Bristol-Myers Squibb, Emerald Health, and TeneoBio, Ariane Herrick: None declared, Maurizio Cutolo Grant/research support from: Bristol-Myers Squibb, Actelion, Celgene, Consultant of: Bristol-Myers Squibb, Speakers bureau: Sigma-Alpha, Ana Cordeiro Consultant of: Ana Cordeiro has acted as a consultant for Roche, Speakers bureau: Ana Cordeiro has received speaker fees from Boehringer Ingelheim, Lilly, and Vitoria, Valderilio F Azevedo Grant/research support from: Abbvie, Janssen, Bristol-Myers Squibb, Boehringer-Ingelheim, Lilly and Novartis, Consultant of: Lilly, Novartis, Janssen, Boehringer-Ingelheim, Amgen, Pfizer and Abbvie, Speakers bureau: Sandoz, Celltrion, Lilly, Novartis, Janssen, Boehringer-Ingelheim, Amgen, Pfizer and Abbvie, Sindhu Johnson Grant/research support from: Boehringer Ingelheim, Corbus Pharmaceuticals, GlaxoSmithKline, Roche, Merck, Bayer, Consultant of: Boehringer Ingelheim, Ikaria, Christian Stock Employee of: Employee of Boehringer Ingelheim, Martina Gahlemann Employee of: Employee of Boehringer Ingelheim, Lizette Moros Employee of: Lizette Moros is an employee of Boehringer Ingelheim, Margarida Alves Employee of: Employee of Boehringer Ingelheim, Maureen Mayes Grant/research support from: Maureen Mayes has received grants from Boehringer Ingelheim, Corbus, CSL Behring, Eicos, and Galapagos, Consultant of: Maureen Mayes has acted as a consultant for Boehringer Ingelheim, Eicos, and Galapagos.

Abstract
UNLABELLED BMD changes in patients under tight control (monitored at 3-month intervals with adjustment of therapy guided by bone turnover markers) and routine management (controlled once a year) were compared. After 1 year, the femoral neck BMD increased significantly in the tight control compared to the routine management group. INTRODUCTION We intended to ascertain whether tight control (i.e., follow-up visits and bone turnover markers/BTM/and parathyroid hormone/PTH/monitoring at 3-month intervals) strategy achieves a statistically greater increase in bone mineral density over the observation period than standard follow-up care (i.e., bone densitometry at 1-year intervals, without BTM monitoring). METHODS We studied involutional osteoporotic patients newly enrolled into chronic care. One hundred and eleven patients underwent tight control, while another 113 received routine treatment (with follow-up visits scheduled at > 1-year intervals). We compared the changes in bone mineral density reflected by the results of bone mineral density (BMD) measurements of the lumbar spine and of the left femoral neck. Statistical analyses were performed with version 22 of the SPSS software package. RESULTS In the group of patients under tight control, baseline and follow-up median BMD values were 0.842/0.881 g/cm2 at the L1-4 vertebrae and 0.745/0.749 g/cm2 at the femoral neck. In the group under routine care, the corresponding values were 0.903/0.915 g/cm2 and 0.742/0.72 g/cm2, respectively. The relative changes of the bone mineral density of the femoral neck was significantly (p = 0.041) higher in patients under tight control than in those receiving routine care; however, BMD changes in the lumbar spine were not statistically different. CONCLUSION Our findings suggest that adopting tight control as a new therapeutic strategy might be justified in the osteoporosis management. In fact, a greater improvement of BMD can be achieved by treatment according to these principles.

Abstract
Summary
Aim: We investigated the circulatory characteristics of patients suffering of primary and secondary Raynaud’s syndrome. Patients, methods: We examined 106 patients presenting with the classical symptoms of Raynaud’s syndrom (47 primary, 59 secondary) by hand perfusion scintigraphy developed by our Department of Nuclear Medicine. After visual evaluation we analyzed the images semiquantitatively, using the finger to palm ratio. We statistically compared the patients with primary and those with secondary Raynaud’s syndrome. Results: By visual evaluation we constated regional perfusion disturbances in 42 from 59 patients with secondary Raynaud’s syndrome. However, this was observed in only 3 from 47 patients with the primary form of this disease. This difference was statistically significant (p <0.001). Semiquantitative analysis showed that the finger/palm ratios (FPR) were significantly lower (p <0.05) for the patients with primary Raynaud’s syndrome. No differences in the FPR values concerning sex or right and left side. Conclusion: The hand perfusion scintigraphy with 99mTc-DTPA is a noninvasive, cost effective diagnostic tool, which objectively reflects the global and regional microcirculatory abnormalities of the hands, and provides quantitative data for follow-up.

Abstract
Lipoxin A4 (LXA4) and scrum amyloid A (SAA) are endogenous negative and positive modulators of inflammation, respectively. Both molecules bind the shared lipoxin A4 receptor (ALX) and elicit opposing effects on the production of inflammatory cytokines and matrix metalloproteinases. The aim of these studies is to examine the divergence of the intracellular signaling pathways triggered by lipid LXA4 (1 nM) and protein SAA (200 nM) ligands of ALX. Phospholipase D (PLD) is a phosphohydrolase enzyme that catalyzes the generation of phosphatidic acid (PA) from membrane phospholipids. Our results showed that in fibroblast-like synoviocytes, activation of PLD occurred only in response to LXA4, and not SAA. PA (30 μM) mimicked LXA4 and demonstrated inhibition of IL-8 production induced by SAA or interleukin-1β. In sharp contrast to LXA4, SAA confirmed the stimulation of IL-8 release as determined previously. Taken together, these findings suggest that two physiologic ligands sharing the common ALX receptor, LXA4 and SAA, differentially regulate the level of PLD activation and differentially modulate IL-8. These results may have important implications for understanding the regulation of inflammatory responses under physiologic and pathological conditions.

Abstract
Recent studies have suggested increased plasticity of differentiated cells within the intestine to act both as intestinal stem cells (ISCs) and tumour-initiating cells. However, little is known of the processes that regulate this plasticity. Our previous work has shown that activating mutations of Kras or the NF-κB pathway can drive dedifferentiation of intestinal cells lacking Apc. To investigate this process further, we profiled both cells undergoing dedifferentiation in vitro and tumours generated from these cells in vivo by gene expression analysis. Remarkably, no clear differences were observed in the tumours; however, during dedifferentiation in vitro we found a marked upregulation of TGFβ signalling, a pathway commonly mutated in colorectal cancer (CRC). Genetic inactivation of TGFβ type 1 receptor (Tgfbr1/Alk5) enhanced the ability of KrasG12D/+ mutation to drive dedifferentiation and markedly accelerated tumourigenesis. Mechanistically this is associated with a marked activation of MAPK signalling. Tumourigenesis from differentiated compartments is potently inhibited by MEK inhibition. Taken together, we show that tumours arising in differentiated compartments will be exposed to different suppressive signals, for example, TGFβ and blockade of these makes tumourigenesis more efficient from this compartment.

Abstract
The adult organism is characterized by remarkable plasticity, which enables efficient regeneration and restoration of homeostasis after damage. When aberrantly activated, this plasticity contributes to tumour initiation and progression. Here we review recent advances in this field with a focus on cell fate changes and the epithelial-mesenchymal transition-two distinct, yet closely related, forms of plasticity with fundamental roles in homeostasis and cancer.

Abstract
Lipoxin A4 (LXA4) is a potent eicosanoid that inhibits IL-1β-induced activation of human fibroblast-like synoviocytes (FLS) via the LXA4 receptor (ALXR). Serum amyloid A (SAA) is an acute phase reactant with cytokine-like properties. SAA has been shown to bind the same seven transmembrane G protein-coupled receptor ligated by LXA4. Here we compared the inflammatory responses of lipid (LXA4) and peptide (SAA) ligands in human FLS via the shared ALX and characterized their downstream signaling. LXA4 induced stimulation of tissue inhibitors of metalloproteinase-2, whereas SAA induced interleukin-8 and matrix metalloproteinase-3 production. SAA up-regulated NF-kB and AP-1 DNA binding activity, while LXA4 markedly inhibited these responses after IL-1β stimulation. A human IL-8 promoter luciferase construct was transfected into CHO cells stably expressing ALXR in order to determine the role of NF-kB and/or AP-1 in the regulation of IL-8 gene expression. The NF-kB pathway proved to be the preeminent for the biological responses elicited by both ligands. These findings suggest that two endogenous molecules, targeting a common receptor, could participate in the pathogenesis of inflammatory arthritis by differentially regulating inflammatory responses in tissues expressing the ALXR.

Abstract
The bacterial antibiotic anisomycin is known to induce apoptosis by activating several mitogen-activated protein kinases and by inhibiting protein synthesis. In this study, the influence of p53 protein on the apoptosis-inducing effect of anisomycin was investigated. The effect of protein synthesis-inhibiting concentration of anisomycin on apoptotic events was analyzed using Western blot, DNA fragmentation, and cell viability assays in wild-type PC12 and in mutant p53 protein expressing p143p53PC12 cells. Anisomycin stimulated the main apoptotic pathways in both cell lines, but p143p53PC12 cells showed lower sensitivity to the drug than their wild-type counterparts. Anisomycin caused the activation of the main stress kinases, phosphorylation of the p53 protein and the eukaryotic initiation factor eIF2α, proteolytic cleavage of protein kinase R, Bid, caspase-9 and -3. Furthermore, anisomycin treatment led to the activation of TRAIL and caspase-8, two proteins involved in the extrinsic apoptotic pathway. All these changes were stronger and more sustained in wtPC12 cells. In the presence of the dominant inhibitory p53 protein, p53- dependent genes involved in the regulation of apoptosis may be less transcribed and this can lead to the decrease of apoptotic processes in p143p53PC12 cells.

Abstract
Transmembrane proteins play crucial role in signaling, ion transport, nutrient uptake, as well as in maintaining the dynamic equilibrium between the internal and external environment of cells. Despite their important biological functions and abundance, less than 2% of all determined structures are transmembrane proteins. Given the persisting technical difficulties associated with high resolution structure determination of transmembrane proteins, additional methods, including computational and experimental techniques remain vital in promoting our understanding of their topologies, 3D structures, functions and interactions. Here we report a method for the high-throughput determination of extracellular segments of transmembrane proteins based on the identification of surface labeled and biotin captured peptide fragments by LC/MS/MS. We show that reliable identification of extracellular protein segments increases the accuracy and reliability of existing topology prediction algorithms. Using the experimental topology data as constraints, our improved prediction tool provides accurate and reliable topology models for hundreds of human transmembrane proteins.

Abstract
Species belonging to Aspergillus section Cervini are characterised by radiate or short columnar, fawn coloured, uniseriate conidial heads. The morphology of the taxa in this section is very similar and isolates assigned to these species are frequently misidentified. In this study, a polyphasic approach was applied using morphological characters, extrolite data, temperature profiles and partial BenA, CaM and RPB2 sequences to examine the relationships within this section. Based on this taxonomic approach the section Cervini is resolved in ten species including six new species: A. acidohumus, A. christenseniae, A. novoguineensis, A. subnutans, A. transcarpathicus and A. wisconsinensis. A dichotomous key for the identification is provided.

Abstract
Aspergillus section Nidulantes includes species with striking morphological characters, such as biseriate conidiophores with brown-pigmented stipes, and if present, the production of ascomata embedded in masses of Hülle cells with often reddish brown ascospores. The majority of species in this section have a sexual state, which were named Emericella in the dual name nomenclature system. In the present study, strains belonging to subgenus Nidulantes were subjected to multilocus molecular phylogenetic analyses using internal transcribed spacer region (ITS), partial β-tubulin (BenA), calmodulin (CaM) and RNA polymerase II second largest subunit (RPB2) sequences. Nine sections are accepted in subgenus Nidulantes including the new section Cavernicolus. A polyphasic approach using morphological characters, extrolites, physiological characters and phylogeny was applied to investigate the taxonomy of section Nidulantes. Based on this approach, section Nidulantes is subdivided in seven clades and 65 species, and 10 species are described here as new. Morphological characters including colour, shape, size, and ornamentation of ascospores, shape and size of conidia and vesicles, growth temperatures are important for identifying species. Many species of section Nidulantes produce the carcinogenic mycotoxin sterigmatocystin. The most important mycotoxins in Aspergillus section Nidulantes are aflatoxins, sterigmatocystin, emestrin, fumitremorgins, asteltoxins, and paxillin while other extrolites are useful drugs or drug lead candidates such as echinocandins, mulundocandins, calbistrins, varitriols, variecolins and terrain. Aflatoxin B1 is produced by four species: A. astellatus, A. miraensis, A. olivicola, and A. venezuelensis.

Abstract
The TSTMP database is designed to help the target selection of human transmembrane proteins for structural genomics projects and structure modeling studies. Currently, there are only 60 known 3D structures among the polytopic human transmembrane proteins and about a further 600 could be modeled using existing structures. Although there are a great number of human transmembrane protein structures left to be determined, surprisingly only a small fraction of these proteins have 'selected' (or above) status according to the current version the TargetDB/TargetTrack database. This figure is even worse regarding those transmembrane proteins that would contribute the most to the structural coverage of the human transmembrane proteome. The database was built by sorting out proteins from the human transmembrane proteome with known structure and searching for suitable model structures for the remaining proteins by combining the results of a state-of-the-art transmembrane specific fold recognition algorithm and a sequence similarity search algorithm. Proteins were searched for homologues among the human transmembrane proteins in order to select targets whose successful structure determination would lead to the best structural coverage of the human transmembrane proteome. The pipeline constructed for creating the TSTMP database guarantees to keep the database up-to-date. The database is available at http://tstmp.enzim.ttk.mta.hu.

Abstract
Aspergillus is one of the economically most important fungal genera. Recently, the ICN adopted the single name nomenclature which has forced mycologists to choose one name for fungi (e.g. Aspergillus, Fusarium, Penicillium, etc.). Previously two proposals for the single name nomenclature in Aspergillus were presented: one attributes the name "Aspergillus" to clades comprising seven different teleomorphic names, by supporting the monophyly of this genus; the other proposes that Aspergillus is a non-monophyletic genus, by preserving the Aspergillus name only to species belonging to subgenus Circumdati and maintaining the sexual names in the other clades. The aim of our study was to test the monophyly of Aspergilli by two independent phylogenetic analyses using a multilocus phylogenetic approach. One test was run on the publicly available coding regions of six genes (RPB1, RPB2, Tsr1, Cct8, BenA, CaM), using 96 species of Penicillium, Aspergillus and related taxa. Bayesian (MrBayes) and Ultrafast Maximum Likelihood (IQ-Tree) and Rapid Maximum Likelihood (RaxML) analyses gave the same conclusion highly supporting the monophyly of Aspergillus. The other analyses were also performed by using publicly available data of the coding sequences of nine loci (18S rRNA, 5,8S rRNA, 28S rRNA (D1-D2), RPB1, RPB2, CaM, BenA, Tsr1, Cct8) of 204 different species. Both Bayesian (MrBayes) and Maximum Likelihood (RAxML) trees obtained by this second round of independent analyses strongly supported the monophyly of the genus Aspergillus. The stability test also confirmed the robustness of the results obtained. In conclusion, statistical analyses have rejected the hypothesis that the Aspergilli are non-monophyletic, and provided robust arguments that the genus is monophyletic and clearly separated from the monophyletic genus Penicillium. There is no phylogenetic evidence to split Aspergillus into several genera and the name Aspergillus can be used for all the species belonging to Aspergillus i.e. the clade comprising the subgenera Aspergillus, Circumdati, Fumigati, Nidulantes, section Cremei and certain species which were formerly part of the genera Phialosimplex and Polypaecilum. Section Cremei and the clade containing Polypaecilum and Phialosimplex are proposed as new subgenera of Aspergillus. The phylogenetic analysis also clearly shows that Aspergillus clavatoflavus and A. zonatus do not belong to the genus Aspergillus. Aspergillus clavatoflavus is therefore transferred to a new genus Aspergillago as Aspergillago clavatoflavus and A. zonatus was transferred to Penicilliopsis as P. zonata. The subgenera of Aspergillus share similar extrolite profiles indicating that the genus is one large genus from a chemotaxonomical point of view. Morphological and ecophysiological characteristics of the species also strongly indicate that Aspergillus is a polythetic class in phenotypic characters.

Abstract
UNLABELLED The TOPDOM database-originally created as a collection of domains and motifs located consistently on the same side of the membranes in α-helical transmembrane proteins-has been updated and extended by taking into consideration consistently localized domains and motifs in globular proteins, too. By taking advantage of the recently developed CCTOP algorithm to determine the type of a protein and predict topology in case of transmembrane proteins, and by applying a thorough search for domains and motifs as well as utilizing the most up-to-date version of all source databases, we managed to reach a 6-fold increase in the size of the whole database and a 2-fold increase in the number of transmembrane proteins. AVAILABILITY AND IMPLEMENTATION TOPDOM database is available at http://topdom.enzim.hu The webpage utilizes the common Apache, PHP5 and MySQL software to provide the user interface for accessing and searching the database. The database itself is generated on a high performance computer. CONTACT tusnady.gabor@ttk.mta.hu SUPPLEMENTARY INFORMATION Supplementary data are available at Bioinformatics online.

Abstract
Excessive production of interleukin-6 (IL-6) and metalloproteinases (MMPs) has been implicated in the pathogenesis of rheumatoid arthritis. Lipoxin A4 (LXA4) and transforming growth factor (32 (TGF-|32) have potential anti-inflammatory activities; these two mediators were tested to determine how they affect IL-1β-dependent release of IL-6 and MMPs in human fibroblast-like synoviocytes. The results revealed dramatic differences between the mediators: TGF-β2 acted synergistically with IL-1β to stimulate IL-6 protein levels, whereas LXA4 inhibited IL-6 expression in a dose- and time-dependent manner. Inhibition, by LXA4 was abrogated when cells were pre-incubated with antibody against the ALXR (Lipoxin A4 Receptor) TGF-β2 by itself had no significant effect on IL-6 or MMP levels. LXA4, at nanomolar concentrations, altered the MMP-1 and MMP-3 expression levels of IL-1β and TGF-β2 stimulated fibroblast-like synoviocytes. Furthermore, IL-1β and TGF-β2 up-regulated ALXR mRNA. These results demonstrate, for the first time, that ALXR mediate the effects of LXA4 on inflammatory responses after stimulation of fibroblast-like synoviocytes with IL-1β plus TGF-β2. These activities might constitute an important mechanism by which LXA4 regulates synovial fibroblast activation.

Abstract
The fallopian tubes represent a highly important structure for ovarian carcinogenesis. They provide the passage of eutopic endometrium from the uterus, as well as metastatic cells from the ovaries. A direct source of tumor cells for ovarian cancer was also recently confirmed in the fallopian tubes. The authors present a case report of an incidental tubal endometrioid carcinoma with the coexistence of adenomyosis.

Abstract
Penicillium is a diverse genus occurring worldwide and its species play important roles as decomposers of organic materials and cause destructive rots in the food industry where they produce a wide range of mycotoxins. Other species are considered enzyme factories or are common indoor air allergens. Although DNA sequences are essential for robust identification of Penicillium species, there is currently no comprehensive, verified reference database for the genus. To coincide with the move to one fungus one name in the International Code of Nomenclature for algae, fungi and plants, the generic concept of Penicillium was re-defined to accommodate species from other genera, such as Chromocleista, Eladia, Eupenicillium, Torulomyces and Thysanophora, which together comprise a large monophyletic clade. As a result of this, and the many new species described in recent years, it was necessary to update the list of accepted species in Penicillium. The genus currently contains 354 accepted species, including new combinations for Aspergillus crystallinus, A. malodoratus and A. paradoxus, which belong to Penicillium section Paradoxa. To add to the taxonomic value of the list, we also provide information on each accepted species MycoBank number, living ex-type strains and provide GenBank accession numbers to ITS, β-tubulin, calmodulin and RPB2 sequences, thereby supplying a verified set of sequences for each species of the genus. In addition to the nomenclatural list, we recommend a standard working method for species descriptions and identifications to be adopted by laboratories working on this genus.

Abstract
Although in vivo targeting of tumors using fluorescently labeled probes has greatly gained in importance over the last few years, most of the clinically applied reagents lack tumor cell specificity. Our novel tumor cell-penetrating peptide-based probe (TPP) recognizes an epitope of Hsp70 that is exclusively present on the cell surface of a broad variety of human and mouse tumors and metastases, but not on normal tissues. Because of the rapid turnover rate of membrane Hsp70, fluorescently labeled TPP is continuously internalized into syngeneic, spontaneous, chemically/genetically induced and xenograft tumors following intravenous administration, thereby enabling site-specific labeling of primary tumors and metastases. In contrast with the commercially available nonpeptide small molecule αvβ3-integrin antagonist IntegriSense, TPP exhibits a significantly higher tumor-to-background contrast and stronger tumor-specific signal intensity in all tested tumor models. Moreover, in contrast with IntegriSense, TPP reliably differentiates between tumor cells and cells of the tumor microenvironment, such as tumor-associated macrophages and fibroblasts, which were found to be membrane-Hsp70 negative. Therefore, TPP provides a useful tool for multimodal imaging of tumors and metastases that might help to improve our understanding of tumorigenesis and allow the establishment of improved diagnostic procedures and more accurate therapeutic monitoring. TPP might also be a promising platform for tumor-specific drug delivery and other Hsp70-based targeted therapies.

Abstract
Tumor cell plasticity is an event that has been observed in several malignancies. In fact, most of the solid tumors are characterized by cellular heterogeneity and undergo constant changes as the tumor develops. The increased plasticity displayed by these cells allows them to acquire additional properties, enabling epithelial-mesenchymal transitions, dedifferentiation and the acquisition of stem cell-like properties. Here we discuss the particular importance of an inflammatory microenvironment for the bidirectional control of cellular plasticity and the potential for therapeutic intervention.

Abstract
Aspergillus comprises a diverse group of species based on morphological, physiological and phylogenetic characters, which significantly impact biotechnology, food production, indoor environments and human health. Aspergillus was traditionally associated with nine teleomorph genera, but phylogenetic data suggest that together with genera such as Polypaecilum, Phialosimplex, Dichotomomyces and Cristaspora, Aspergillus forms a monophyletic clade closely related to Penicillium. Changes in the International Code of Nomenclature for algae, fungi and plants resulted in the move to one name per species, meaning that a decision had to be made whether to keep Aspergillus as one big genus or to split it into several smaller genera. The International Commission of Penicillium and Aspergillus decided to keep Aspergillus instead of using smaller genera. In this paper, we present the arguments for this decision. We introduce new combinations for accepted species presently lacking an Aspergillus name and provide an updated accepted species list for the genus, now containing 339 species. To add to the scientific value of the list, we include information about living ex-type culture collection numbers and GenBank accession numbers for available representative ITS, calmodulin, β-tubulin and RPB2 sequences. In addition, we recommend a standard working technique for Aspergillus and propose calmodulin as a secondary identification marker.

Abstract
OBJECTIVES We demonstrate a case report of the patient who suffered from advanced gastric cancer and was treated by means of surgery and HIPEC. BACKGROUND Gastric cancer is a therapeutic challenge in the European countries due to late diagnosis, advanced stages of the disease in time of diagnosis and early recurrence in cases where a radical surgery is possible. METHOD The patient with an advanced gastric cancer (pT3N2M1 - peritoneal and ovarian metastases) was treated by means of radical surgery in combination with hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) and early postoperative intraperitoneal chemotherapy (EPIC). Surgical treatment was followed by a standard chemotherapy. Due to recurrence, there was the second look surgery one year later again with HIPEC procedure. RESULTS Patient survived 32 months after diagnosis and despite intraperitoneal recurrence she never developed clinically significant ascites and she never suffered from intestinal obstruction. CONCLUSION This case demonstrate a potential benefit of new oncosurgical approach -radical surgery + HIPEC + EPIC in the treatment of gastric cancers (Tab. 2, Fig. 6, Graph 4, Ref. 18).

Abstract
The course of histopathological alterations within jejunal graft architecture during the initial adaptation phase in the host body was investigated. Graft tissues were compared to the intestinal tissues of the recipients. This study demonstrates: (1) renewal of intestinal epithelial lining in the graft biopsies during initial hours after transplantation is more likely caused by migration and extension of remaining epithelial cells than by their increased mitotic division. (2) Distinct decrease in histopathological injury was observed in transplanted grafts after 6h, but the morphometrical parameters, particularly villus height and wall thickness, remained altered. (3) Significant decrease in apoptotic cell death in the epithelial lining within 6h of graft recirculation was accompanied by no effect on apoptosis levels of the cells in lamina propria connective tissue. (4) Although the apoptosis level in the connective tissue cells was not modulated in the grafts within the first hour after transplantation, caspase-3 dependent apoptosis was decreased significantly.

Abstract
Over the past decade, the microenvironment of gastrointestinal tumors has gained increasing attention because it is required for tumor initiation, progression, and metastasis. The tumor microenvironment has many components and has been recognized as one of the major hallmarks of epithelial cancers. Although therapeutic strategies for gastrointestinal cancer have previously focused on the epithelial cell compartment, there is increasing interest in reagents that alter the microenvironment, based on reported interactions among gastrointestinal epithelial, stromal, and immune cells during gastrointestinal carcinogenesis. We review the different cellular components of the gastrointestinal tumor microenvironment and their functions in carcinogenesis and discuss how improving our understanding of the complex stromal network could lead to new therapeutic strategies.
