Abstract
A magzat immunológiai felismerése a sikeres terhesség feltétele. Ennek alapját a
decidualizáció teremti meg, melynek révén létrejön az embrió befogadására
alkalmas szöveti környezet. A decidualizáció során kialakuló speciális szövet
endokrin és immunológiai feladatokat ellátó önálló szerv, amely szigorúan
szabályozott kapcsolatot tart fenn az embrióval, vagyis az embrió maga is aktív
résztvevője a megtermékenyülésnek. A terhesség immunológiájának megértése
szempontjából rendkívül fontos, hogy a magzat és az anya immunrendszere közötti
kölcsönhatás dinamikusan változik, vagyis a terhesség immunológiai stádiumokkal
jellemezhető. Napjainkban a terhesség kronológiáját az immunológiai órával
reprezentálják („immune clock”): e szerint az implantáció feltétele a korábban
elképzelhetetlennek tartott gyulladásos miliő, amelyet a magzati növekedéshez
szükséges antiinflammatorikus környezet vált fel, és amelyet a szülés
megindulásához nélkülözhetetlen, újfent gyulladásos immunválasz kialakulása
követ. A terhességhez történő alkalmazkodás nagy rugalmasságot igényel az anyai
immunrendszer részéről annak érdekében, hogy egyidejűleg valósuljon meg az apai
alloantigénekkel szembeni tolerancia, a placenta és a magzat optimális fejlődése
és a fertőzések/xenobiotikumok elleni védelem. Mindez csak speciális és szorosan
együttműködő immunmiliő kialakításával érhető el az anyai–magzati felszínen,
ahol a természetes és az adaptív immunrendszer sejtes és szolúbilis összetevői
ráhangolódnak a hormonális miliőre, együttműködnek a mikrobiommal, és megfelelő
választ adnak a trophoblastok immunmoduláló hatásaira. A természetes és az
adaptív folyamatok összehangoltságának megváltozása infertilitáshoz, a
beágyazódás zavaraihoz és terhességi szövődményekhez vezethet, ezért
megismerésének diagnosztikus és terápiás következményei vannak. Orv Hetil. 2023;
164(51): 2006–2015.

Abstract
Chub (reophillic cyprinids) is one of the most sensitive bioindicator fish of environmental changes following anthropogenic activities. The improvement of different biotechnological procedures could help support its conservation and strengthen the natural populations. The aim of this study was to compare the effects of two different hormonal agents (carp pituitary extract and Ovopel™) on various motility parameters (pMOT-%, DAP-μm, VCL μm s-1, VSL-μm s-1, LIN-%, ALH-μm, BCF-Hz) of fresh and cryopreserved/thawed sperm (stored at 4 °C for 6 h). Additionally, we sought to develop a novel, large-scale cryopreservation method for chub sperm, assessing freezing methods (Styrofoam box and a controlled-rate freezer) and different containers (0.5, 5 mL straw and 4 mL cryotube) for sperm cryopreservation. The results of this study indicated no difference between the carp pituitary extract and Ovopel treated groups in either the fresh or frozen/thawed sperm (at 0, 3, 6, hour post thawing, P = 0.4351). In contrast, the quality of the thawed chub sperm was negatively affected after 3 h chilled storage in both hormonal treatments (P = 0.0036, P < 0.0001). When assessing the motility parameters of the sperm between the 5 mL straw and 4 mL cryotube groups cryopreserved in a Styrofoam Box, no difference was observed (P = 0.103). Additionally, sperm loaded in 4 mL cryotubes showed no difference in motility when cryopreserved with either the Styrofoam box or controlled-rate freezer methods (P = 0.109). A similar hatching rate was observed in sperm preserved using the Styrofoam box (35 ± 7 %) and controlled rate freezer (25 ± 9 %) methods (P = 0.300). In a second fertilization trial, hatching rate was similar between control (72 ± 19 %) and cryopreserved (4 mL cryotube and Styrofoam box, 61 ± 5 %) groups. (P = 0.257). Based on our findings and its standard features (less species specific, precise dose calculation), Ovopel can be a good candidate for the stimulation of spermiation in chub sperm prior to cryopreservation. Furthermore, our study presents a novel and applicable method for the large-scale cryopreservation of chub sperm.

Abstract
INTRODUCTION Data describing real-world treatment patterns in patients with metastatic urothelial carcinoma (mUC) in Central-Eastern Europe are scarce, and data from Hungary have not been published. This retrospective, nationwide, real-world study investigated patient characteristics, treatment patterns, comorbidities, and clinical outcomes in patients with mUC in Hungary. METHODS Adults diagnosed with mUC from January 2016 through June 2021 were identified using the National Health Insurance Fund Administration database. Overall survival (OS) was estimated using the Kaplan-Meier method. RESULTS In total, 2523 patients with mUC were identified. Median follow-up was 7.1 months. Overall, 50% of patients received an identified systemic anticancer treatment; within this subgroup, first-line treatment was platinum-based chemotherapy (PBC) in 86%, non-PBC in 8%, and immune checkpoint inhibitor (ICI) in 6%. The proportion of patients receiving treatment increased from 41% in 2016 to 59% in 2020, driven by increased use of first-line PBC or first-line ICI treatment. Comorbidities were more common in patients receiving first-line ICI treatment vs PBC or non-PBC and in patients receiving carboplatin + gemcitabine vs cisplatin + gemcitabine. Overall, only 24% received a second-line treatment. Unadjusted median OS from the start of first-line treatment in the PBC, non-PBC, and ICI subgroups was 12.8, 7.5, and 6.3 months, respectively. Median OS from date of diagnosis in untreated patients was 7.8 months. OS comparisons adjusted for differences in baseline characteristics between subgroups could not be performed. CONCLUSION To our knowledge, this is the first study to assess treatment patterns in patients with mUC in clinical practice in Hungary, using the national health insurance database. Rates of first- and second-line treatment were consistent with those observed in other countries. Avelumab first-line maintenance treatment became available for reimbursement in Hungary in late 2022, after the study period. Given the evolving landscape of reimbursed treatments in Hungary, further analyses are warranted.

Abstract
The calibration of an ion detection system was carried out for protons and carbon ions from a few tens of keV up to about 1 MeV energies. A Thomson spectrometer deflecting the particle beam accelerated from a laser plasma creates the ion spectra on a phosphor screen behind a micro-channel plate (MCP), which are recorded by a camera. During calibration, the ion spectra simultaneously hit the slotted CR-39 track detector installed in front of the MCP and, passing through the adjacent CR-39 stripes, the MCP. The calibration provides the ratio of the interpolated values between two consecutive stripes of the camera signal and the total number of particles recorded on the corresponding stripe of CR-39. The efficiency of proton detection by CR-39 was also measured in a conventional accelerator beam and found to drop by 20% below 100 keV.

Abstract
Mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) represent a rare diagnosis of the gastro-entero-pancreatic tract. Evidence from the current literature regarding their epidemiology, biology, and management is of variable quality and conflicting. Based on available data, the MiNEN has an aggressive biological behaviour, mostly driven by its (often high-grade) neuroendocrine component, and a dismal prognosis. In most cases, the non-neuroendocrine component is of adenocarcinoma histology. Due to limitations in diagnostic methods and poor awareness within the scientific community, the incidence of MiNENs may be underestimated. In the absence of data from clinical trials, MiNENs are commonly treated according to the standard of care for pure neuroendocrine carcinomas or adenocarcinomas from the same sites of origin, based on the assumption of a biological similarity to their pure counterparts. However, little is known about the molecular aberrations of MiNENs, and their pathogenesis remains controversial; molecular/genetic studies conducted so far point towards a common monoclonal origin of the two components. In addition, mutations in tumour-associated genes, including TP53, BRAF, and KRAS, and microsatellite instability have emerged as potential drivers of MiNENs. This systematic review (91 full manuscripts or abstracts in English language) summarises the current reported literature on clinical, pathological, survival, and molecular/genetic data on MiNENs.

Abstract
Abstract
Background
Hungary has the highest incidence of lung cancer in the world (GLOBOCAN, 2018). Since lung cancer is rarely treatable in its advanced stage, one possible way to reduce mortality is early diagnosis and subsequent treatment. The possibility and necessity of introducing low-dose computed tomography (LDCT) lung cancer screening as a public health programme is a current and relevant health policy issue.
Methods
A Markov cohort model was built to assess the cost-effectiveness of such a risk group screening programme in Hungary. The model was populated with transition probabilities and resource utilization data derived from the HUNCHEST Hungarian lung cancer screening trial. The model results are presented in incremental cost-effectiveness ratio.
Results
A closed cohort of 10,000 smokers with the average starting age of 59 years was followed over life-time horizon and screened for lung cancer annually until the age of 74. Compared to the current scenario of no organized lung cancer screening in Hungary, the model resulted in an additional 0.1614 life-year gained per individual and an additional 0.2924 disease-free life-year gained per individual with annual screening frequency. The incremental cost-effectiveness ratio was EUR 608 indicating that assessed intervention is cost-effective in the analyzed setting. Sensitivity analyses confirmed the robustness of the model results.
Conclusions
Results suggest that introducing low-dose computed tomography screening for lung cancer is a cost-effective intervention in Hungary. Considering the exceptionally high incidence and mortality of lung cancer in Hungary, the population could benefit from such a risk group screening programme.
Key messages
Low-dose computed tomography screening for lung cancer is cost-effectiveness in the Hungarian setting. Policy makers are encouraged to consider the introduction of a risk group screening programme.

Abstract
Itraconazole is a fungicide drug which has low bioavailability due to its poor water solubility. Amorphous solid dispersion (ASD) is a tool that has the potential to greatly increase the dissolution rate and extent of compounds. In this work, the dissolution of tablets containing the ASD of itraconazole with either hydroxypropyl methylcellulose (HPMC) or vinylpyrrolidone-vinyl acetate copolymer (PVPVA) was compared in order to find a formulation which can prevent the drug from the precipitation caused by magnesium stearate. Formulations containing the PVPVA-based ASD with HPMC included in various forms could reach 90% dissolution in 2 h, while HPMC-based ASDs could release 100% of the drug. However, HPMC-based ASD had remarkably poor grindability and low bulk density, which limited its processability and applicability. The latter issue could be resolved by roller compacting the ASD, which significantly increases the bulk density and the flowability of the powder blends used for tableting. This roller compaction step might be a base for the industrial application of HPMC-based, electrospun ASDs.

Abstract
![]()
Scalable
immunoassay multiplexing offers a route to creating rapid
point-of-care (POC) diagnostics. We present a method for multiplexing
immunoassays on the surface of a complementary metal oxide semiconductor
(CMOS) sensor array integrated circuit (IC) without the use of physical
separators such as wells or channels. Major advantages of using a
CMOS sensor array include low mass-manufacturing costs, the possibility
to multiplex multiple assays on a single IC, and improved signal when
averaging multiple sensors, along with providing a platform where
wash steps can be incorporated to maximize selectivity and sensitivity
compared to paper based lateral flow immunoassay. The device was able
to differentiate between samples containing either, neither, or both
rabbit anti-mouse (RAM) antibodies and/or anti-HIV gp120 antibodies
in serum using a gold-nanoparticle promoted silver enhancement immunoassay.
HIV antibody concentrations down to 100 μg/mL were readily detected,
which is three times lower than those typically found in infected
humans (300–500 μg/mL), and the limit of detection was
10 μg/mL.

Abstract
INTRODUCTION Peritoneal dissemination accompanied by ascites formation is common in epithelial ovarian cancer (EOC). Adhesion molecules are crucial in metastatic spread and the latter involves epithelial-mesenchymal transition (EMT). This study aimed at: (1) clarifying whether E-cadherin and β-catenin expression and proliferative activity in metastatic ovarian cancer are inter-related; (2) Identifying possible correlations between cell adhesion molecular expression profiles, the proliferative activity and p53 expression of tumor cells and tumor grade and stage; (3) testing the cytology microarray (CMA) technique in analyzing metastasis formation. MATERIAL AND METHODS Both tumorous and ascitic samples from 27 EOC patients were examined by using tissue microarray (TMA) and cytology microarray (CMA), respectively. CMA blocks were constructed using cores from each cell block of the ascitic specimens. Expression of E-cadherin, β-catenin, Ki-67 and p53 was immunohistochemically detected both in TMA and CMA blocks. RESULTS E-cadherin expression was higher in ascitic cells than in primary tumor cells (p = .294). β-catenin expression was significantly lower in ascitic cells than in primary tumor cells (p = .006). Expression of Ki-67 was lower and expression of p53 was higher in primary tumors than in ascitic cells, for p53 the difference was significant (p = .001). Both Ki-67 and p53 expression elevated significantly in high-grade primary tumor cells and in ascites cells (p = .039, and p = .004, respectively). CONCLUSION Epithelial-mesenchymal transition- mesenchymal-epithelial transition is suggested as the best descriptive term for our IHC observations which accompany increased proliferative activity of ascitic cells. The CMA method is an adequate and reliable method for the analysis of ascitic tumor cells disseminating from ovarian malignancies.

Abstract
A neutron polarizer using four successive reflections on m = 2.5 supermirrors was built and installed at the GINA neutron reflectometer at the Budapest Neutron Centre. This simple setup exhibits 99.6% polarizing efficiency with 80% transmitted intensity of the selected polarization state. Due to the geometry, the higher harmonics in the incident beam are filtered out, while the optical axis of the beam remains intact for easy mounting and dismounting the device in an existing experimental setup.

Abstract
Disadvantageous crystallization phenomenon of amorphous itraconazole (ITR) occurring in the course of dissolution process was investigated in this work. A perfectly amorphous form (solid dispersion) of the drug was generated by the electroblowing method (with vinylpyrrolidone-vinyl acetate copolymer), and the obtained fibers were formulated into tablets. Incomplete dissolution of the tablets was noticed under the circumstances of the standard dissolution test, after which a precipitated material could be filtered. The filtrate consisted of ITR and stearic acid since no magnesium content was detectable in it. In parallel with dissolution, ITR forms an insoluble associate, stabilized by hydrogen bonding, with stearic acid deriving from magnesium stearate. This is why dissolution curves do not have the plateaus at 100%. Two ways are viable to tackle this issue: change the lubricant (with sodium stearyl fumarate >95% dissolution can be accomplished) or alter the polymer in the solid dispersion to a type being able to form hydrogen bonds with ITR (e.g., hydroxypropyl methylcellulose). This work draws attention to one possible phenomenon that can lead to a deterioration of originally good dissolution of an amorphous solid dispersion.

Abstract
INTRODUCTION Despite a progress in the management of patients with atrial fibrillation this arrhythmia is one of the major causes of stroke, heart failure, sudden death and cardiovascular morbidity. Oral anticoagulation with vitamin K antagonist or non-vitamin K antagonist markedly reduces stroke and mortality in atrial fibrillation patients. AIM To estimate the real-life vitamin K antagonist and non-vitamin K antagonist oral anticoagulant treatment in past years in Hungary. METHOD Analysis of the National Health Insurance Administation database for atrial fibrillation (BNO: I48) between 2010-2015. We assumed that AF patient would turn to health care provides at least once either as inpatients or outpatients in a 5-year period. The patient was accepted as adherent after 6 months therapy and at least 80% oral anticoagulant prescription. RESULTS The prevalence of AF in Hungary is 3%. The mortality rate of AF 7%-10% per year. The adherence of the old oral anticoagulant treatment was 55%, but it was 69% among patient treated by "new" oral anticoagulant treatment. However, one third of the patients are not treated by effective old or new oral anticoagulant treatment. CONCLUSIONS We need more effort to improve the effective and high adherence oral anticoagulant therapy in our country. Orv Hetil. 2017; 158(39): 1545-1549.

Abstract
In order to elucidate whether cytokine mechanisms of the cingulate cortex (cctx) are important in the central regulation of homeostasis, in the present study, feeding-metabolic effects of direct bilateral microinjection of interleukin-1β (IL-1β) into the cctx of the rat have been investigated. Short- (2h), medium (12h) and long-term (24h) food and water intakes and body temperature were measured after the intracerebral administration of this primary cytokine or vehicle solution, with or without paracetamol pretreatment. The effect of IL-1β on the blood glucose level of animals was examined in glucose tolerance test (GTT), and concentrations of relevant plasma metabolites (total cholesterol, HDL, LDH, triglycerides, uric acid) were additionally also determined following the above microinjections. In contrast to causing no major alteration in the food and water intakes, the cytokine treatment evoked significant increase in the body temperature of the rats. Prostaglandin-mediated mechanisms were shown to have important role in the mode of this action of IL-1β, since paracetamol pretreatment partially prevented the development of the above mentioned hyperthermia. In the GTT, no considerable difference was observed between the blood glucose levels of the cytokine treated and control animals. Following IL-1β microinjection, however, significant decrease of HDL and total cholesterol was found. Our present findings indicate that elucidating the IL-1β mediated homeostatic control mechanisms in the cingulate cortex may lead to the better understanding not only the regulatory entities of the healthy organism but also those found in obesity, diabetes mellitus and other worldwide rapidly spreading feeding-metabolic disorders.

Abstract
BACKGROUND AND AIMS Some crucial associations between obesity-related altered adipokine levels and the main factors of atherosclerotic, atherothrombotic processes are not fully known. We analysed the relationships of classic adipokines, namely leptin, resistin, adiponectin, tumour necrosis factor-alpha (TNF-α), interleukin 6 (IL-6) with the markers of platelet activation, including mean platelet volume (MPV), platelet surface/soluble P-selectin, platelet-derived microparticles (PMPs), the parameters of coagulation abnormalities and common carotid intima-media thickness (IMT) in obese patients with or without atherosclerotic comorbidities in comparison to age- and sex-matched controls. METHODS AND RESULTS We enrolled 154 obese individuals, including 98 suffering from atherosclerotic concomitant conditions, 56 free of atherosclerotic comorbidities and 62 healthy controls. Plasma levels of leptin, resistin, adiponectin, TNF-α, IL-6, soluble P-selectin, and plasminogen activator inhibitor-1 antigen (PAI-1 ag) were analysed by ELISA. Platelet surface P-selectin and PMPs were measured by flow cytometry. IMT was detected by ultrasonography. Adipokines were closely associated with markers of platelet hyperactivity, hypercoagulability, hypofibrinolysis and IMT. Significant independent associations were found between leptin and platelet count (p < 0.0001), MPV (p = 0.019), PMPs (p < 0.0001), fibrinogen (p = 0.001), factor VIII (FVIII) activity (p = 0.035); adiponectin and PAI-1 ag (p = 0.035); resistin and soluble P-selectin (p = 0.002); TNF-α and PAI-1 ag (p < 0.0001); and IL-6 and fibrinogen (p = 0.011). Finally, leptin (p = 0.0005), adiponectin (p = 0.019), IL-6 (p = 0.001), MPV (p = 0.0003), PMP (p = 0.008), and FVIII activity (p = 0.043) were independent predictors of IMT. CONCLUSION Overall, we suggest that in obese subjects altered adipokine levels play a key role in common carotid atherosclerosis both directly and through haemostatic parameters.

Abstract
The mediodorsal prefrontal cortex (mdPFC) is a key structure of the central glucose-monitoring (GM) neural network. Previous studies indicate that intracerebral streptozotocin (STZ) microinjection-induced destruction of local chemosensory neurons results in feeding and metabolic alterations. The present experiments aimed to examine whether STZ microinjection into the mdPFC causes metabolic deficits. To do so, glucose tolerance test (GTT) and measurements of plasma metabolites were performed in STZ-treated or control rats. Intraperitoneal D-glucose load was delivered 20 min or 4 weeks following the intracerebral microinjection of STZ or saline (acute or subacute GTT, respectively). The STZ-treated rats displayed acute glucose intolerance: at the 120th min of the test, blood glucose level of these rats was significantly higher than that of the ones in the control group. When determining the plasma level of various metabolites, 30 min following the intracerebral STZ or saline microinjection, the triglyceride concentration of the STZ-treated rats was found to be reduced compared with that of the control rats. The GM neurons of the mdPFC are suggested to be involved in the organization of complex metabolic processes by which these chemosensory cells contribute to adaptive control mechanisms of the maintenance of homeostasis.

Abstract
Transcriptional changes in superficial spinal dorsal horn neurons (SSDHN) are essential in the development and maintenance of prolonged pain. Epigenetic mechanisms including post-translational modifications in histones are pivotal in regulating transcription. Here, we report that phosphorylation of serine 10 (S10) in histone 3 (H3) specifically occurs in a group of rat SSDHN following the activation of nociceptive primary sensory neurons by burn injury, capsaicin application or sustained electrical activation of nociceptive primary sensory nerve fibres. In contrast, brief thermal or mechanical nociceptive stimuli, which fail to induce tissue injury or inflammation, do not produce the same effect. Blocking N-methyl-D-aspartate receptors or activation of extracellular signal-regulated kinases 1 and 2, or blocking or deleting the mitogen- and stress-activated kinases 1 and 2 (MSK1/2), which phosphorylate S10 in H3, inhibit up-regulation in phosphorylated S10 in H3 (p-S10H3) as well as fos transcription, a down-stream effect of p-S10H3. Deleting MSK1/2 also inhibits the development of carrageenan-induced inflammatory heat hyperalgesia in mice. We propose that p-S10H3 is a novel marker for nociceptive processing in SSDHN with high relevance to transcriptional changes and the development of prolonged pain.

Abstract
Little is known about the genetic background of keratocystic odontogenic tumors (KCOT, odontogenic keratocysts). Our aim was to characterize genomic aberrations in sporadic KCOT using cDNA-expression arrays and array-comparative genomic hybridization. For cDNA-expression arrays, 10 KCOT specimens and 20 fetal tooth germs were studied. Quantitative real-time reverse-transcription/polymerase chain-reaction and immunohistochemical studies were also undertaken. Several genes were over-expressed in 12q13, including cytokeratin 6B ( KRT6B) (≈ 10-fold), epidermal growth factor receptor ERBB3 (~ 4.7-fold), and glioma-associated oncogene homologue 1 ( GLI1) (~ 5- to 12-fold). One amplicon (~ 0.7 Mega base pairs [Mbp]), covering several genes involved in the regulation of cell growth, was found in 12q13.2. Deletions were found in 3q13.1, 5p14.3, and 7q31.3, including the cell-adhesion-related gene cadherin 18 ( CDH18) and leukocyte cell adhesion molecule ( ALCAM, MEMD). Over-expressed and amplified genes in 12q13, also reported in several other tumors and cell lines, may contribute to the persistent growth characteristics of KCOT.

Abstract
OBJECTIVE Complications contribute largely to the economic gravity of diabetes mellitus (DM). How they arise and are treated differs substantially between countries. This paper assesses the total annual, direct, and indirect cost of severe hypoglycemia events (SHEs) in nine European countries: Bulgaria, Croatia, the Czech Republic, Greece, Hungary, Macedonia/the former Yugoslav Republic of Macedonia (MK), Poland, Slovenia, and Spain. METHODS Data was collected on epidemiology, treatment structure, SHE-driven resource consumption, and unit costs. Two systematic reviews-on the SHE rates and the resources used for treatment-and data on the days-of-work lost due to SHE along with salaries and employment rates were used. The total SHE cost in each country was calculated and how the differences are driven by individual parameters was analysed. RESULTS The annual costs of SHEs varied in absolute terms from €379,951.25 in MK up to €58,429,684.40 in Spain, or-when expressed per one drug-treated DM patient-from €5.47 in Bulgaria up to €17.74 in Spain. Indirect cost constituted between 6.01% (MK) and 26.49% (Hungary) of the total cost. The differences between countries are driven mostly by the cost of treating a single event, and this is related to general differences in prices. LIMITATIONS The main limitation is the lack of good quality data in some parts, and the necessity to use mean-value imputations, experts' opinions, etc. Additionally, we only considered DM treatment as the SHE driver, while other elements, e.g. style of living, may contribute substantially. CONCLUSIONS A common framework can be applied to estimate the economic burden of SHE in various countries, allowing one to identify the drivers of differences in cost. Treating DM is complex, and so no resolute conclusions ought to be drawn as to whether SHE management is better in one country than another.

Abstract
PURPOSE Diabetic retinopathy is one of the leading causes of blindness. There are several risk factors, such as the duration of diabetes or glycemic control of the patient; however, several biochemical factors also alter the process. Our aim was to investigate the role of soluble E-selectin in the formation of diabetic retinopathy. PATIENTS AND METHODS Fifty-seven patients (37 female and 20 male, aged 61.71 ± 12.31 years) and 14 healthy control subjects (ten female and four male, aged 63.06 ± 10.46 years) were enrolled in the study. We measured the soluble E-selectin level in the plasma of patients by ELISA. All patients underwent careful ophthalmological examination, including ophthalmoscopy and color fundus photography, while diabetic retinopathy grading was performed in line with the 2012 classification of the American Academy of Ophthalmology (AAO). RESULTS The soluble E-selectin level was significantly higher in patients with diabetes compared to controls (32.95 ng/ml vs. 26.55 ng/ml, p = 0.03). Dividing patients into groups by the presence of retinopathy, the E-selectin level was also significantly higher in the retinopathy group (p < 0.05). When we examined diabetic patients by the severity of retinopathy (groups A, B, and C, by the guidelines of the AAO), however, we did not find any significant difference in soluble E-selectin levels, although it tended to be higher in group B. CONCLUSIONS An elevated E-selectin level can play a role in the development of diabetic retinopathy, but it does not seem to alter disease severity. However, glycemic control and the reduction of cardiovascular risk factors may also alter the level of E-selectin that might play a role in the prevention of diabetic retinopathy.

Abstract
Inflammatory cytokines can impair the skin barrier, but the question as to whether barrier alterations affect keratinocyte immune responses remains unanswered. The aim of this study was to investigate whether immune-mediated skin inflammation differs between severe atopic dermatitis patients with or without filaggrin mutation. The levels of filaggrin, inflammatory T helper 2 polarizing cytokines (thymic stromal lymphopoietin (TSLP) and interleukin 33 (IL-33)) and chemokine (C-C motif) ligand 27 (CCL27), histological severity markers, T and dendritic cell counts in biopsies from lesional skin of severe atopic dermatitis patients with and without filaggrin mutation and healthy skin were quantified by immunohistochemistry. The results were confirmed by quantitative PCR analyses. No significant differences were found between the 2 patient groups. Expression of atopic dermatitis-specific cytokines showed significant correlation with histological severity. These findings suggest that the immune-mediated skin inflammation (represented by keratinocyte-derived factors, T cell and dendritic cell counts) is similar in the 2 patient groups with severe atopic dermatitis, and that immune activation is connected to the severity of the disease rather than to the origin of barrier alterations.

Abstract
The aim of this study was to reveal phenotype/genotype characteristics of verotoxigenic Escherichia coli (VTEC) and multidrug resistant E. coli in food products of animal origin confiscated as illegal import at Austrian, German and Slovenian airports. VTEC isolates were obtained by using ISO guidelines 16654:2001 for O157 VTEC or ISO/ TS13136:2012 for non-O157 VTEC, with additional use of the RIDASCREEN® Verotoxin immunoassay. The testing of 1526 samples resulted in 15 VTEC isolates (1.0%) primarily isolated from hard cheese from Turkey and Balkan countries. Genotyping for virulence by using a miniaturized microarray identified a wide range of virulence determinants. One VTEC isolate (O26:H46) possessing intimin (eae) and all other essential genes of Locus of Enterocyte Effacement (LEE) was designated as enterohemorrhagic E. coli (EHEC). None of the other VTEC strains belonged to serogroups O157, O145, O111, O104 or O103. VTEC strains harbored either stx(1) (variants stx1(a) or stx(1c)) or st(x2) (variants stx(2a), stx(2b), stx(2a/d) or stx(2c/d)) genes. Pulsed field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) demonstrated high genetic diversity and identified three new sequence types (STs): 4505, 4506 and 4507. Food samples collected from the Vienna airport were also tested for E. coli quantities using the ISO 16649:2001, and for detection of multidrug resistant phenotypes and genotypes. The resulting 113 commensal E. coli isolates were first tested in a pre-screening against 6 selected antimicrobials to demonstrate multidrug resistance. The resulting 14 multidrug resistant (MDR) E. coli isolates, representing 0.9% of the samples, were subjected to further resistance phenotyping and to microarray analyses targeting genetic markers of antimicrobial resistance and virulence. Genotyping revealed various combinations of resistance determinants as well as the presence of class 1, class 2 integrons. The isolates harbored 6 to 11 antibiotic resistance genes as well as 1 to 14 virulence genes. In this panel of 14 MDR E. coli two strains proved to carry CTX-M type ESBLs, and one single isolate was identified as enteropathogenic E. coli (EPEC). In general, isolates carrying a high number of resistance determinants had lower number of virulence genes and vice versa. In conclusion, this first pilot study on the prevalence of VTEC and of MDR/ESBL E. coli in illegally imported food products of animal origin suggests that these strains could represent reservoirs for dissemination of potentially new types of pathogenic and MDR E. coli in Europe.

Abstract
The nucleus accumbens (NAcc), an important basal forebrain structure, has a central integratory function in the control of feeding and metabolism. The primary cytokine interleukin-1β (IL-1β) exerts its neuromodulatory effects on the endocrine functions both centrally and peripherally. The present study was designed to elucidate the possible consequences of direct administration of IL-1β into the NAcc on the endocrine regulation of metabolism. Plasma concentrations of insulin and leptin, two key hormones in the homeostatic control were determined 15 minutes after a single bilateral microinjection of IL-1β into the NAcc of adult male Wistar rats, and the effects were compared with those found in vehicle treated control animals. Insulin plasma levels of the cytokine treated animals were significantly higher than those parameters of the control rats. No differences were found in leptin plasma concentrations between the two groups. Our findings show that IL-1β mediated processes in the NAcc have important roles in the central neuroendocrine control.

Abstract
The setup, capabilities, and operation parameters of the neutron reflectometer GINA, the recently installed "Grazing Incidence Neutron Apparatus" at the Budapest Neutron Centre, are introduced. GINA, a dance-floor-type, constant-energy, angle-dispersive reflectometer is equipped with a 2D position-sensitive detector to study specular and off-specular scattering. Wavelength options between 3.2 and 5.7 Å are available for unpolarized and polarized neutrons. Spin polarization and analysis are achieved by magnetized transmission supermirrors and radio-frequency adiabatic spin flippers. As a result of vertical focusing by a five-element pyrolytic graphite monochromator, the reflected intensity from a 20 × 20 mm(2) sample has been doubled. GINA is dedicated to studies of magnetic films and heterostructures, but unpolarized options for non-magnetic films, membranes, and other surfaces are also provided. Shortly after its startup, reflectivity values as low as 3 × 10(-5) have been measured by the instrument. The instrument capabilities are demonstrated by a non-polarized and a polarized reflectivity experiment on a Si wafer and on a magnetic film of [(62)Ni/(nat)Ni](5) isotope-periodic layer composition. The facility is now open for the international user community. Its further development is underway establishing new sample environment options and spin analysis of off-specularly scattered radiation as well as further decreasing the background.

Abstract
Cellular interactions among platelets, leukocytes and endothelial cells are considered as a major cause of inflammation and atherosclerosis in many diseases. Via exposed surface receptors and released soluble substances, activated platelets play a crucial role in the initiation of inflammatory processes, resulting in endothelial injury and leading to formation of atherosclerotic plaque with possible thrombotic complications. Classic anti-platelet treatments (e.g. cyclooxygenase inhibitor or ADP-receptor antagonist) have favorable effects in patients with vascular diseases, but they also have several limitations such as increased bleeding risk or non-responsiveness. Thus, the need and opportunities for developing novel therapeutic inhibitors for platelet-mediated events are obvious. Animal and (pre)clinical human studies have suggested that some recently produced specific antagonists of P-selectin from α-granules, as well as its main ligand/receptor P-selectin Glycoprotein Ligand-1, the two major platelet chemokines CXCL4 and CCL5, as well as CD40L, may be considered potential new candidates in the treatment of atherogenesis and inflammation. In this review, we summarize the pathophysiological roles of these effectors in platelet activation and acute or chronic inflammation, and discuss the latest findings on promising antagonistic agents in basic and clinical studies in the prevention of platelet-mediated cellular interactions.

Abstract
INTRODUCTION One-carbon cycle is involved in two essential physiological processes: The synthesis of purins and pyrimidines required for DNA synthesis and repair. The other is the methylation with the methionine cycle. These one-carbon groups are served by the tetrahydrofolate and the S-adenosylmethionine. Deficiencies of the folate, or other abnormalities within the methionine pathway lead to elevated homocysteine levels. These disorders have been implicated in placental diseases. Earlier studies have shown that homocysteine levels are elevated by patients with severe pre-eclampsia than by healthy pregnant normotensive women. Methylenetetrahydrofolate reductase (MTHFR) gene C677T missense mutation has a high frequency by patients with HELLP syndrome and connected with elevated serum homocysteine levels. The reduced-folate carrier (RFC-1) facilitates the internalization of 5-methyltetrahydrofolate from the blood into peripheral cells. The mutation G80A this gene leads to higher plasma folate. OBJECTIVES Our aim was to identify the polymorphism of these two genes in samples of severe pre-eclamptic patients and healthy controls. METHODS Blood samples were collected from healthy pregnant normotensive women (n=82) and women with pre-eclampsia (n=75). DNA was isolated and quantitative real-time PCR method combined with melting curve analysis was performed for the detection of the two polymorphisms. Statistical analysis was performed with the STATISTICA software package. RESULTS The frequency of the A allele in the RFC-1 gene was 46.57% by healthy pregnant and 41% by severe pre-eclamptic patients. The overall distribution of genotypes was not significantly different between the control and pre-eclamptic groups (p=0.58). In the study groups by the MTHFR gene the frequency of the T was 32% in pre-eclamptics, and 35.92% in controls. Similarly the overall distribution of genotypes was not significantly different between the two study groups (p=0.15). CONCLUSION In hypertensive disorders of the pregnancy the one-carbon cycle is disturbed. We studied single nucleotide mutations in the genes of two enzymes involved in the cycle. We determined the allele and genotype frequencies in healthy control and pre-eclamptic patients and found no significant differences. Further examinations of other genetical compounds can help to understand the elevated homocysteine levels in pre-eclampsia.
