Abstract
AIM To compare the technical quality and long-term outcomes of root canal treatment by general practitioners of a Swedish Public Dental Service, before and after an endodontic education including Ni-Ti rotary technique (NiTiR). METHODOLOGY A random sample was compiled, comprising one root filled tooth from each of 830 patients, treated by 69 general practitioners participating in the education: 414 teeth root filled in 2002, pre-education, using primarily stainless steel instrumentation and filling by lateral compaction, and 416 teeth root filled post-education (2005), using mainly NiTiR and single-cone obturation. Follow-up radiographs taken in 2009 were evaluated alongside immediate post-filling radiographs from 2002 to 2005. The density and length of the root fillings were registered. Periapical status was assessed by the Periapical Index (PAI), using two definitions of disease: apical periodontitis (AP) (PAI 3 + 4 + 5) and definite AP (PAI 4 + 5). Tooth survival was registered. Root fillings pre- and post-education were compared using chi-square and Fisher's exact tests. Crude extraction rates per 100 years were calculated for comparison of tooth survival. Explanatory variables (type of tooth, root filling quality, periapical status, marginal bone loss, type and quality of coronal restoration) in relation to the dependent variable (AP at follow-up) were analysed by multivariable logistic regression. RESULTS Follow-up data were available for 229 (55%) of teeth treated pre- and 288 (69%) treated post-education: both tooth survival (P < 0.001) and root filling quality were significantly higher (P < 0.001) in the latter. However, there was no corresponding improvement in periapical status. Both pre- and post-education, root fillings with definite AP on completion of treatment had significantly higher odds of AP or definite AP at follow-up. For teeth treated post-education, inadequate root filling quality was significantly associated with AP at follow-up. CONCLUSIONS Despite a higher tooth survival rate and a significant improvement in technical quality of root fillings after the education, there was no corresponding improvement in periapical status.

Abstract
The role of mycotoxins in the microbial competition in an ecosystem or on the same host plant is still unclear. Therefore, a laboratory study was conducted to evaluate the influence of mycotoxins on growth and mycotoxin production of Fusarium and Alternaria fungi. Fusarium culmorum Fc13, Fusarium graminearum Fg23 and two Alternaria tenuissima isolates (At18 and At220) were incubated on wheat kernels supplemented with alternariol (AOH), tetramic acid derivates (TeA), deoxynivalenol (DON) and zearalenone (ZEA) in an in vitro test system. Fungal biomass was quantified by determining ergosterol content. Three Fusarium toxins (DON, nivalenol and ZEA) and three Alternaria toxins (AOH, alternariol methyl ether (AME) and altenuene) were analysed by HPLC-MS/MS. If Alternaria strains grew in wheat kernels spiked with Fusarium mycotoxins, their growth rates were moderately increased, their AOH and AME production was enhanced and they were simultaneously capable of degrading the Fusarium mycotoxins DON and ZEA. In contrast, both Fusarium strains behaved quite differently. The growth rate of Fc13 was not distinctly influenced, while Fg23 increased its growth in wheat kernels spiked with AOH. TeA depressed the ergosterol content in Fc13 as well as in Fg23. The DON production of Fc13 was slightly depressed, whereas the ZEA production was significantly increased. In contrast, Fg23 restricted its ZEA production. Both Fusarium strains were not capable of degrading the Alternaria mycotoxin AOH. Mycotoxins might play an important role in the interfungal competitive processes. They influence growth rates and mycotoxin production of the antagonistic combatants. The observed effects between phytopathogenic Alternaria and Fusarium strains and their mycotoxins aid the understanding of the complexity of microbial competitive behaviour in natural environments.

Abstract
AIM Several population-based studies have shown that long term prognosis of ulcerative colitis (UC) may be better than previously reported. The aim of this study was to evaluate the course of UC in a referral center cohort in the pre-biologic era and to identify possible prognostic factors. METHODS All patients with established diagnosis of UC have been extracted from our GI Unit IBD Database. Clinical and demographic characteristics of all patients were recorded at the time of diagnosis. The disease course was retrospectively evaluated considering four primary end points: change in disease extension, need of corticosteroids, need of immunomodulators, and need of colectomy. The Kaplan-Meier survival method was used to estimate the cumulative probability of a course free of the outcome of interest. RESULTS Eight hundred and seven UC patients diagnosed between 1984 and 2008 have been included: 21.8% had proctitis, 47.6% had distal colitis and 30.6% had extensive colitis. The median follow up after diagnosis was 91 months (range 12-596). The probability of extension of proctitis within 10 years was 39.7%. In the whole cohort, the 10 years probability of receiving corticosteroids and immunomodulators was 46.7% and 12.4%, respectively. The 10-year probability of colectomy was 6.5%. Extensive colitis was associated with a higher probability of receiving corticosteroids, immunomodulators and surgery. CONCLUSION Long-term prognosis of UC is favourable for the majority of patients. Extensive colitis is the most relevant negative prognostic factor. Results from our referral center study are similar to that reported in population-based studies. Further studies are required to assess the possible impact of biologics and new treatment strategies on long term outcomes.

Abstract
Rhodococcus equi is an animal pathogen that causes infrequent but challenging infections in immunocompromised individuals, few of which have been described in solid organ transplant recipients. Common clinical presentations include indolent cough, fever, and dyspnea, with necrotizing pneumonia and cavitation. We report a case of a dense right upper lung pneumonia with resultant R. equi bacteremia in a renal transplant recipient. Our patient initially responded to antibiotic treatment with resolution of bacteremia and clinical recovery, followed by interval progression in her right upper lobe consolidation on follow-up computed tomography scans. She underwent lobectomy for definitive therapy with resolution of symptoms. Lobectomy can be utilized in isolated infection after antibiotic failure with excellent clinical outcomes.

Abstract
OBJECTIVE To investigate a possible correlation between the volume of the tubal ectopic pregnancy (EP) measured by vaginal-ultrasound (VUS) and methotrexate (MTX) therapy outcome. STUDY DESIGN Data of EP volume measured by one expert-sonographer, viability, clinical symptoms, previous IVF/insemination, follow-up of β-hCG and progesterone levels, and treatment of EP was collected of 100 patients with sonographically diagnosed EP, who attended the Department of Obstetrics and Gynecology of the Medical University Vienna between March 2008 and September 2011. RESULTS The mean volume of EP (mVol.) in the group with successful MTX therapy (n = 38) was 5.11 ml, 95%CI [2.4; 7.8] with a median 3.2 ml, IQR [5.0], in the group with unsuccessful MTX treatment (n = 11) it was 15.24 ml, 95%CI [-2.6; 33.1], with a median 4.4 ml, IQR [11.4]. We could observe a trend towards a lower mVol. in the successful MTX group (5.11 ml vs. 15.24 ml). We could not show a significant correlation (u-test p = 0.208). CONCLUSION A clear tendency was observed towards a lower mVol. in the successful MTX therapy group, but we could not verify a statistically significant correlation of volume of EP and MTX therapy outcome most likely due to the small sample size. This was the first study investigating the correlation of volume of EP and MTX therapy outcome as principal question.

Abstract
We present a fast and low-cost delay generator for terahertz (THz) waves that transfers a rotational motion of a transparent dielectric cube into an effective THz delay. The device is easily implemented in the THz beam path and allows for coherent sampling over 40 ps with a scan rate of hundreds of hertz. Furthermore, we show that our approach is particularly suitable for fast THz imaging.

Abstract
The aim of this study was to explicate and describe the qualitative meaning of successful clinical and organizational change in endodontic practice, following a comprehensive implementation program, including the integration of the nickel-titanium-rotary-technique. After an educational intervention in the Public Dental Service in a Swedish county, thematic in-depth interviews were conducted, with special reference to the participants' experience of the successful change. Interviews with four participants, were purposively selected on the basis of occupation (dentist, dental assistant, receptionist, clinical manager), for a phenomenological human scientific analysis. Four constituents were identified as necessary for the invariant, general structure of the phenomenon: 1) disclosed motivation, 2) allowance for individual learning processes, 3) continuous professional collaboration, and 4) a facilitating educator. The perceived requirements for achieving successful clinical and organizational change in endodontic practice were clinical relevance, an atmosphere which facilitated discussion and allowance for individual learning patterns. The qualities required in the educator were acknowledged competence with respect to scientific knowledge and clinical expertise, as well as familiarity with conditions at the dental clinics. The results indicate a complex interelationship among various aspects of the successful change process.

Abstract
The brain receives and integrates environmental and metabolic information, transforms these signals into adequate neuronal circuit activities, and generates physiological behaviors to promote energy homeostasis. The responsible neuronal circuitries show lifetime plasticity and guaranty metabolic health and survival. However, this highly evolved organization has become challenged nowadays by chronic overload with nutrients and reduced physical activity, which results in an ever-increasing number of obese individuals worldwide. Research within the last two decades has aimed to decipher the responsible molecular and cellular mechanisms for regulation of the hypothalamic melanocortin neurons, which have a key role in the control of food intake and energy metabolism. This review maps the central connections of the melanocortin system and highlights its global position and divergent character in physiological and pathological metabolic events. Moreover, recently uncovered molecular and cellular processes in hypothalamic neurons and glial cells that drive plastic morphological and physiological changes in these cells, and account for regulation of food intake and energy metabolism, are brought into focus. Finally, potential functional interactions between metabolic disorders and psychiatric diseases are discussed.

Abstract
Es wurden Schmelzkurven sowie ORD- und ZD-Spektren von DNS-Lösungen verschiedenen Salzgehaltes gemessen. In Übereinstimmung mit den aus der Literatur bekannten Daten wurde mit abnehmendem Salzgehalt eine Destabilisierung der DNS-Doppelhelix gefunden, die Doppelstrangstruktur und die Basenaufstockung bleiben jedoch weitgehend erhalten. Die Doppelstrangstruktur wird bei niedrigen Ionenstärken erst nach thermischer oder Säuredenaturierung zerstört. Die Basenaufstockung wird dabei ebenfalls reduziert. Hohe Salzkonzentrationen (4,5 ᴍ NaCl) bewirken Strangtrennungen und ungeordnete Basendesorientierungen. Ein Vergleich der Absorptions-, ORD- und ZD-Daten zeigt, daß die Art der Konformationsänderungen von der Art der äußeren Einwirkungen abhängt

Abstract
Absolute values for the removal rates of CH2(ã1A1) by NH3, CH3NH2, CH3OH, HCl, and HF have been determined in the gas phase at low pressures and room temperature. CH2(ã1A1) was generated by pulsed laser photolysis of CH2CO. The measurements were carried out by observing the laser induced fluorescence of 1CH2 after excitation by a pulsed laser as a function of the time delay between the photolysis and analysis pulses. The overall rate constants were found to be 2.4, 2.4, 2.3, 1.6 and 0.13 · 1014 cm3/mol s, respectively.
NH2 was shown by LIF detection to be a primary product of the reaction of 1CH2 with NH3. The intersystem crossing channel of 1CH2 was investigated by monitoring the formation of CH2(X̃3B1) with laser magnetic resonance. LMR absorption intensities of 3CH2 resulting from quenching of 1CH2 in the presence and absence of the reactant R were compared under otherwise identical conditions. The branching ratios of quenching versus total removal of 1CH2, turned out to be 0.30, 0.13 and 0.98 for NH3, CH3OH, and HF, respectively.

Abstract
BACKGROUND Various devices have been developed to facilitate liver transection and reduce blood loss in liver resections. None of these has proven superiority compared with the classical clamp-crushing technique. This randomized clinical trial compared the effectiveness and safety of stapler transection with that of clamp-crushing during open liver resection. METHODS Patients admitted for elective open liver resection between January 2010 and October 2011 were assigned randomly to stapler transection or the clamp-crushing technique. The primary endpoint was the total amount of intraoperative blood loss. Secondary endpoints included transection time, duration of operation, complication rates and resection margins. RESULTS A total of 130 patients were enrolled, 65 to clamp-crushing and 65 to stapler transection. There was no difference between groups in total intraoperative blood loss: median (i.q.r.) 1050 (525-1650) versus 925 (450-1425) ml respectively (P = 0·279). The difference in total intraoperative blood loss normalized to the transection surface area was not statistically significant (P = 0·092). Blood loss during parenchymal transection was significantly lower in the stapler transection group (P = 0·002), as were the parenchymal transection time (mean(s.d.) 30(21) versus 9(7) min for clamp-crushing and stapler transection groups respectively; P < 0·001) and total duration of operation (mean(s.d.) 221(86) versus 190(85) min; P = 0·047). There were no significant differences in postoperative morbidity (P = 0·863) or mortality (P = 0·684) between groups. CONCLUSION Stapler transection is a safe technique but does not reduce intraoperative blood loss in elective liver resection compared with the clamp-crushing technique.

Abstract
BACKGROUND To assess the prevalence of cannabis use and dependence in a population of schizophrenic inpatients and to compare schizophrenics with and without cannabis consumption. METHODS One hundred one schizophrenic patients were examined during their first week of hospitalization. They answered the PANNS scale of schizophrenia, the CAGE and the Fagerström questionnaire, and the DSM-IV-TR criteria for cannabis, alcohol, opiates, and nicotine use dependence were checked. We also assessed socio-demographic characteristics, the motive of cannabis consumption, and the number of cannabis joints and alcoholic drinks taken. RESULTS The prevalence of cannabis consumption was 33.6% among schizophrenic inpatients. Schizophrenics consuming cannabis were younger than non-schizophrenics (33.3 vs. 44.7 years p < 0.0001), more often male (77 vs. 54%, p = 0.02) and had been hospitalized for the first time in psychiatry earlier (24.3 vs. 31.3 p = 0.003). Eighty-eight percent of cannabis consumers were dependent on cannabis. They were more often dependent on opiates (17 vs. 0%) and alcohol (32 vs. 7.4%, p = 0.001) and presented compulsive buying more often (48 vs. 27%, p = 0.04). Logistic regression revealed that factors associated to cannabis consumption among schizophrenics were cannabis dependence, male gender, pathological gambling, opiate dependence, number of joints smoked each day, and compulsive buying. CONCLUSION 33.6% of the schizophrenic patients hospitalized in psychiatry consume cannabis and most of them are dependent on cannabis and alcohol. Hospitalization in psychiatry may provide an opportunity to systematically identify a dependence disorder and to offer appropriate information and treatment.

Abstract
Pure U-[13C18]-labelled cis-zearalenone (cis-ZEA) has been prepared and characterised as internal standard (ISTD) for a reliable quantification of cis-ZEA in contaminated food and feed products. The cis-isomer of the naturally trans-configurated Fusarium mycotoxin zearalenone is often neglected. However, isomerisation easily occurs by exposure of ZEA to (UV-)light. Thus, the applicability of the new cis-ZEA ISTD was demonstrated in a long-term isomerisation study comparing naturally trans-ZEA-contaminated edible oil with spiked edible oil. To estimate the benefits of the newly prepared cis-ZEA ISTD, various approaches to quantify cis-ZEA by high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) were compared. As a result, a significant bias was revealed if no appropriate cis-ZEA standards are used. Furthermore, the new ISTD was applied to the analysis of 15 edible oils by stable isotope dilution analysis in combination with HPLC-electrospray ionisation-MS/MS. One of the maize germ oils showed the presence of cis-ZEA above LOD (≯0.3 μg/kg), whereas two out of 15 maize germ oils were found to be contaminated with trans-ZEA (range 17.0-31.0 μg/kg).

Abstract
INTRODUCTION Gastrokine-1 (GKN1) is a secreted auto-/paracrine protein, described to be expressed in the gastric mucosa. In gastric cancers GKN1 expression is commonly down-regulated. While current research focusses on the exploration of tumor-suppressive properties of GKN1 with regard to its potential clinical use in the treatment of gastroenterologic tumor disease, nothing is known about GKN1 expression and function in other organ systems. We investigated GKN1 expression in placental tissue and cells. MATERIALS AND METHODS GKN1 was localized using immunohistochemistry in first and third trimester placental tissue, hydatidiform moles and various gestational trophoblastic neoplasias. We determined the expression of GKN1 in immunomagnetic bead-separated term placental cells and in choriocarcinoma cell lines. The role of GKN1 for JEG-3 migration was studied using live cell imaging. E-cadherin, MMP-2 and -9, TIMP-1 and -2, as well as urokinase (uPA) expression levels were determined. RESULTS GKN1 is expressed in healthy third trimester placentas. Its expression is specifically limited to the extravillous trophoblast (EVT). GKN1 expression is significantly reduced in choriocarcinoma cell lines and gestational trophoblastic neoplasias. GKN1 attenuates the migration of JEG-3 choriocarcinoma cells in vitro, possibly via AKT-mediated induction of E-cadherin. GKN1 treatment reduced MMP-9 expression in JEG-3. DISCUSSION Besides its role in gastric physiology our results clearly indicate regulatory functions of GKN1 in the EVT at the feto-maternal interface during pregnancy. Based on our findings in the JEG-3 choriocarcinoma cell line, an auto-/paracrine role of GKN1 for EVT motility and villous anchorage at the basal plate is conceivable. Thus, the tumor suppressor GKN1 is expressed in placental EVT and might contribute to the regulation of EVT migration/invasion.

Abstract
Application of mesenchymal stromal cells (MSCs) has been proposed for solid organ transplantation based on their potent immuno-modulatory effects in vitro and in vivo. We investigated the potential of MSCs to improve acceptance of kidney transplants in an MHC-incompatible rat model including isogeneic kidney transplantation (RTx) as control. MSCs were administered i.v. or i.a. at time of transplantation. No immunosuppression was applied. Renal function was monitored by serum-creatinine, histopathology, immunochemistry for graft infiltrating cells and expressions of inflammatory genes. We demonstrated the short-term beneficial effects of MSC injection. In the long term, however, MSC-related life-threatening/shortening events (thrombotic microangiopathy, infarctions, infections) were evident despite decreased T- and B-cell infiltration, lower interstitial inflammation and downregulated inflammatory genes particularly after i.a. MSC injection. We conclude that i.a. MSC administration provides efficient immunomodulation after allogeneic RTx, although timing and co-treatment strategies need further fine-tuning to develop the full potential of powerful cell therapy in solid organ transplantation.

Abstract
We present terahertz (THz) lenses made of highly refracting polymeric compounds which provide a better focusing performance and an increased functionality in comparison to conventional THz lenses. Using mixtures consisting of polypropylene (PP) and alumina as well as PP and zinc sulfide allows a significant increase of the refractive index while simultaneously keeping a low extinction and dispersion. With these new material combinations, lenses with an increased focusing capability are realized. This is evaluated by focal plane measurements using a fiber coupled THz time-domain spectrometer.

Abstract
Abstract
New aspects in the design of forced feed section extruder (FFSE) screws are presented which are based on the understanding of the pressure profiles along the screw. The pressure at the end of the grooves correlates with the throughput characteristics in so far that when the maximum build up of pressure in the solid is exceeded, a kink in the throughput curves occurs due to high energy dissipation. This leads to partial melt film friction in the groove section. This can be avoided by the consequences shown in the paper for the design based on a reduced pressure consumption in the zones subsequent to the feeding zone. All criteria are dealt with analytically so to calculate and predetermine the process behaviour as a function of screw geometry. By the way, the main disadvantages of the FFSE can be kept under control as this new understanding is consequently applied to process as well as to screw design. The results of the process analysis are prooven by experimental work.

Abstract
We use terahertz pulses to induce resonant transitions between the eigenstates of optically generated exciton populations in a high-quality semiconductor quantum well sample. Monitoring the excitonic photoluminescence, we observe transient quenching of the 1s exciton emission, which we attribute to the terahertz-induced 1s-to-2p excitation. Simultaneously, a pronounced enhancement of the 2s exciton emission is observed, despite the 1s-to-2s transition being dipole forbidden. A microscopic many-body theory explains the experimental observations as a Coulomb-scattering mixing of the 2s and 2p states, yielding an effective terahertz transition between the 1s and 2s populations.

Abstract
BACKGROUND Somatostatin analogues (SSA) are widely used in the treatment of patients with functioning and non-functioning neuroendocrine tumours (NET). The aim of our investigation was to evaluate the antiproliferative effect of SSA in patients with pancreatic NET. METHODS We retrospectively analysed records of 43 patients with pancreatic NET treated at our clinic with octreotide long-lasting release as a first-line therapy. The aim of our study was to investigate the overall best response according to the RECIST criteria, overall best response defined as disease control rate (SD+PR), response and disease control rate at 12 months, and time to tumour progression (TTP). RESULTS The mean age (± SD) of the patients (16 female/27 male) at initial diagnosis was 54.7 ± 11.86 years. At the start of therapy, 39 of 43 patients were classified as stage IV according to ENETS-TNM. Tumours were graded, based on MiB-1/Ki67 staining, as G1 (n = 8), G2 (n = 30) or unknown (n = 5). The octreoscan was positive in 37 patients, negative in 2 and unknown in 4 cases. Nineteen patients had functioning tumours, 24 patients had non-functioning tumours. Median overall survival was 98 months, and median TTP was 13 months. Analysis of grading showed a statistically significant influence on TTP when comparing the median TTP for Ki67 >10% with Ki67 <5% (p = 0.009) and Ki67 5-10% (p = 0.036). CONCLUSION SSA may be considered as a first-line treatment for antiproliferative purposes in metastatic NET of the pancreas. Patients with a proliferation index <10% displayed a more durable response compared to those with a higher proliferation index.

Abstract
Liquid crystals (LCs) are becoming increasingly important for applications in the terahertz frequency range. A detailed understanding of the spectroscopic parameters of these materials over a broad frequency range is crucial in order to design customized LC mixtures for improved performance. We present the frequency dependent index of refraction and the absorption coefficients of the nematic liquid crystal 5CB over a frequency range from 0.3 THz to 15 THz using a dispersion-free THz time-domain spectrometer system based on two-color plasma generation and air biased coherent detection (ABCD). We show that the spectra are dominated by multiple strong spectral features mainly at frequencies above 4 THz, originating from intramolecular vibrational modes of the weakly LC molecules.

Abstract
Diverticular disease of the colon is the fifth most important gastrointestinal disease in terms of direct and indirect healthcare costs in western countries. Although most patients with colonic diverticula remain asymptomatic for their whole life, in 20-25% of cases will develop symptoms. Antibiotics are commonly used in the treatment of inflammatory complication of diverticular disease. Several clinical observation suggest a role of rifaximin in the management of symptomatic uncomplicated diverticular disease of the colon. This is a critical review of clinical studies addressing the role of long term administration of rifaximin for the treatment of symptomatic colonic diverticular disease. The evidence from prospective controlled trials suggests that rifaximin is effective for obtaining symptomatic relief in patients with uncomplicated diverticular disease. The therapeutic gain compared with fiber supplementation only is approximately 30%. No definitive conclusion can be drawn regard a possible role of rifaximin for preventing diverticulitis.
