Abstract
There is interest in developing potent, selective, and cell-permeable inhibitors of human ferrous iron and 2-oxoglutarate (2OG) oxygenases for use in functional and target validation studies. The 3-component Betti reaction enables efficient one-step C-7 functionalisation of modified 8-hydroxyquinolines (8HQs) to produce cell-active inhibitors of KDM4 histone demethylases and other 2OG oxygenases; the work exemplifies how a template-based metallo-enzyme inhibitor approach can be used to give biologically active compounds.

Abstract
The rejection process remains the key unsolved issue after transplantation of disparate tissue. The CC chemokine monocyte chemoattractant protein-1 (MCP-1/CCL2) has been reported to be involved in the process of alloimmune interaction. Spiegelmers are l-oligonucleotides that can be designed to bind to pharmacologically relevant target molecules. Here, we tested a high-affinity Spiegelmer-based MCP-1 inhibitor (mNOX-E36) in an allogeneic heart transplant model. Fully vascularized allogeneic heterotopic heart transplantations from BALB/c to C57BL/6 mice were performed. Mice were either treated with the anti-MCP-1-Spiegelmer (mNOX-E36) in monotherapy or in combination with subtherapeutic doses of cyclosporine A (CsA) (10 mg/kgBW/day) for 10 days. Controls received equivalent doses of a non-functional Spiegelmer (revmNOX-E36). Graft survival of allogeneic heart transplants was slightly but significantly prolonged under mNOX-E36 monotherapy (median graft survival 10 day ± 0.7) compared to revmNOX-E36 (median graft survival 7 day ± 0.3; P = 0.001). A synergistic beneficial effect could be seen when mNOX-E36 was administered in combination with subtherapeutic doses of CsA (18 day ± 2.8 versus 7 day ± 0.3; P < 0.0001). Levels of inflammatory cytokines and 'alarmins' were significantly reduced, and the number of F4/80(+) cells was lower under combination therapy (1.8% ± 1.3%; versus 14.6% ± 4.4%; P = 0.0002). This novel inhibitor of the MCP-1/CCR2 axis (mNOX-E36), which has already proven efficacy and tolerability in early clinical trials, alleviates acute rejection processes in allogeneic transplantation especially when combined with subtherapeutic doses of CsA. Thus, mNOX-E36 may have potential as an adjunct immunomodulatory agent.

Abstract
We comment on an unusual strain of Microsporum (M.) audouinii. It was isolated from tinea corporis of a boy who lived in Germany and most likely had acquired his infection during a stay on a farm with animal husbandry in Poland. The strain showed features of M. canis (plenty of markedly rough-walled macroconidia, growth on rice, positive hair perforation) as well as of M. audouinii (white thallus, long macroconidia with central constriction) and in vitro it degraded hair of various mammals. Because its ribosomal internal transcribed spacer region showed 99.9% homology to a M. audouinii reference strain it was finally identified as M. audouinii. We relate these findings with recent observations of M. audouinii causing tinea in Europe. This appraisal suggests that irrespective of an identical ribosomal ITS region distinct M. audouinii strains can display a spectrum of morphological and physiological features that is broader than currently outlined in mycological textbooks. Certain unusual characteristics like an enhanced capacity to utilise keratins may even be associated with unexpected transmission routes. Above all sporadic M. audouinii infections in Europe that bear no relation to an endemic area should be analysed from this perspective.

Abstract
OBJECTIVE To examine whether dairy herds with and without abortion problems differ in their management and prevalence of antibodies against various pathogens, through collecting and analysing data from these herds. MATERIAL AND METHODS Data on management parameters, clinical examinations and serological results were obtained from 48 dairy herds in middle Hessen. Information on the extent of stock renewal, form of animal housing, type of herd occupancy and use of a maternity pen was compiled. A random sample was taken from every herd, consisting of a minimum of three healthy non-lactating cows, three clinically sound puerperal animals, three animals having had an abortion and three clinically healthy pregnant heifers. In these animals, the body condition score was evaluated and a clinical gynaecological examination was performed. Additionally, these animals were serologically examined for the presence of antibodies against the bovine viral diarrhoea virus, Coxiella, Listeria and Neosporacaninum. A comparison between the herds with and without an abortion problem was performed. RESULTS Data of 591 animals from 48 farms was compiled. Thirty-eight herds had an abortion problem. In the affected farms, a maternity pen was used significantly more often and cattle were significantly more frequently housed in free stalls when compared to farms without an abortion problem (p < 0.05). The number of animals serologically positive for Coxiella was significantly higher in herds with abortion problems (p = 0.03). No significant difference was found between the occurrence of antibodies against Listeria and Neospora caninum in herds with or without abortion problems, respectively (p > 0.05). CONCLUSIONS It was identified that in addition to infectious agents, management/husbandry factors that promote the spread of disease are a risk factor for abortion in dairy cattle. Besides taking steps against pathogens, farms with abortion problems have to implement measures to minimize the spread of infection between animals. A critical control point is likely to be the maternity pen.

Abstract
Laparoscopic resection rectopexy is one of the surgical options for the treatment of external rectal prolapse. A standardised and reproducible procedure for this operation is a decisive advantage for such cases. The operation can be divided in 11 substeps, so-called nodal points, which must be reached before further progress can be made and simplify the operation by dividing the procedure into substeps. This manuscript and the accompanying film demonstrate the standardised laparoscopic resection rectopexy as taught in the "Surgical Training Center Tübingen," and performed at the University Hospital of Tübingen.

Abstract
BACKGROUND Periodontal ligament progenitor cells (PDLPs) and PDL stem cells (PDLSCs) are progenitor and stem cells that were isolated from PDL tissues using the outgrowth and single cell isolation methods respectively. The differences between PDLPs and PDLSCs characteristics could be observed from previous studies. However, these cells were obtained from different patients. This study was the first report to compare the characterization of PDLPs and PDLSCs from the same person. MATERIAL AND METHODS The characterization of PDLPs and PDLSCs includes flow cytometry analysis, cell proliferation assay and the assessment of the colony-forming unit fibroblast. The osteogenic differentiation was evaluated by alkaline phosphatase activity, biomineralization (alizarin red staining) and gene expression of osteogenic markers. The adipogenic differentiation was examined by Oil Red O staining and adipocyte-related gene expression. RESULTS Mesenchymal stem cell marker expression and colony-forming unit fibroblast analysis of PDLPs and PDLSCs were similar. However, PDLSCs grew faster than PDLPs on days 3 and 5 of the cell proliferation assay. Both PDLPs and PDLSCs could differentiate into osteoblast and adipocyte-like cells. However, the mineralization of PDLSCs was stronger than that of PDLPs. CONCLUSIONS The characteristics of undifferentiated PDL cells in our study were not significantly impacted by the isolation method. We assumed that both PDLPs and PDLSCs are valuable cell sources for periodontal regeneration. However, PDLSCs have a possible advantage for the regeneration of alveolar bone.

Abstract
Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with [Formula: see text] eV by analyzing cosmic rays with energies above [Formula: see text] eV arriving within an angular separation of approximately 15[Formula: see text]. We characterize the energy distributions inside these regions by two independent methods, one searching for angular dependence of energy-energy correlations and one searching for collimation of energy along the local system of principal axes of the energy distribution. No significant patterns are found with this analysis. The comparison of these measurements with astrophysical scenarios can therefore be used to obtain constraints on related model parameters such as strength of cosmic-ray deflection and density of point sources.

Abstract
Spinocerebellar ataxia type 2 (SCA2) and amyotrophic lateral sclerosis (ALS) are neurodegenerative disorders, caused or modified by an unstable CAG-repeat expansion in the SCA2 gene, which encodes a polyglutamine (polyQ) domain expansion in ataxin-2 (ATXN2). ATXN2 is an RNA-binding protein and interacts with the poly(A)-binding protein PABPC1, localizing to ribosomes at the rough endoplasmic reticulum. Under cell stress, ATXN2, PABPC1 and small ribosomal subunits are relocated to stress granules, where mRNAs are protected from translation and from degradation. It is unknown whether ATXN2 associates preferentially with specific mRNAs or how it modulates RNA processing. Here, we investigated the RNA profile of the liver and cerebellum from Atxn2 knockout (Atxn2 (-/-)) mice at two adult ages, employing oligonucleotide microarrays. Prominent increases were observed for Lsm12/Paip1 (>2-fold), translation modulators known as protein interactor/competitor of ATXN2 and for Plin3/Mttp (>1.3-fold), known as apolipoprotein modulators in agreement with the hepatosteatosis phenotype of the Atxn2 (-/-) mice. Consistent modest upregulations were also observed for many factors in the ribosome and the translation/secretion apparatus. Quantitative reverse transcriptase PCR in liver tissue validated >1.2-fold upregulations for the ribosomal biogenesis modulator Nop10, the ribosomal components Rps10, Rps18, Rpl14, Rpl18, Gnb2l1, the translation initiation factors Eif2s2, Eif3s6, Eif4b, Pabpc1 and the rER translocase factors Srp14, Ssr1, Sec61b. Quantitative immunoblots substantiated the increased abundance of NOP10, RPS3, RPS6, RPS10, RPS18, GNB2L1 in SDS protein fractions, and of PABPC1. In mouse embryonal fibroblasts, ATXN2 absence also enhanced phosphorylation of the ribosomal protein S6 during growth stimulation, while impairing the rate of overall protein synthesis rates, suggesting a block between the enhanced translation drive and the impaired execution. Thus, the physiological role of ATXN2 subtly modifies the abundance of cellular translation factors as well as global translation.

Abstract
BACKGROUND The demographic change in -Germany describes an ongoing process of population development of which the eastern German states tend to be more affected. These ongoing changes have an influence on the reproductive behavior of the population. After twenty-three years of German reunification, the present study has investigated the question to what extent the somatic classification of newborns in Mecklenburg-Pomerania (M-P), Germany, is affected. MATERIAL AND METHODS Newborn singleton births (n=174,084) were classified from the existing data of the German Perinatal Survey between 1994 and 2011. The rate of premature birth, SGA, and LGA rate as well as the rate of low birth weight ≤2,499 g were determined both gender-dependently and independently. In addition, a combined analysis of the rates has been taken into account. The obtained data material from M-P made it possible for the first time to compare by values. National and international reference studies were considered in this comparison. RESULTS In M-P, the premature birth rate is 5.2%; the rate of newborns with low birth weight ≤ 2,499 g is 4.4%. Among newborns of ≤2,499 g and SGA newborns, girls compose a higher percentage (4.7%, 12.5%) compared to boys (4.0%, 7.4%). The premature birth rate and LGA newborns appear conversely. For these, the percentage of boys (5.6%, 12.6%) is higher than that of girls (4.8%, 7.0%). 60.6% of the gender non-specific newborns ≤2,499 g are simultaneously premature newborn infants. Only a very small percentage of 0.5% of SGA newborns is at the same time premature infants and newborns with low birth weight. CONCLUSIONS By getting nationwide country-specific figures, a detailed analysis of the newborns in M-P can be performed. The analysis supports the existing national values and is a helpful addition for practice-oriented advice.

Abstract
Background: Transcriptional repression is a key mechanism driving leukaemogenesis. In acute promyelocytic leukaemia (APL), the fusion protein promyelocytic leukaemia-retinoic acid receptor-α fusion (PML-RARα) recruits transcriptional repressors to myeloid differentiation genes. All-trans-retinoic acid (ATRA) induces the proteasomal degradation of PML-RARα and granulocytic differentiation. Histone deacetylases (HDACs) fall into four classes (I–IV) and contribute to the transcription block caused by PML-RARα. Methods: Immunoblot, flow cytometry, and May-Grünwald–Giemsa staining were used to analyze differentiation and induction of apoptosis. Results: A PML-RARα- and ATRA-dependent differentiation programme induces granulocytic maturation associated with an accumulation of the myeloid transcription factor CCAAT/enhancer binding protein (C/EBP)ɛ and of the surface protein CD11b. While this process protects APL cells from inhibitors of class I HDAC activity, inhibition of all Zinc-dependent HDACs (classes I, II, and IV) with the pan-HDACi (histone deacetylase inhibitor(s)) LBH589 induces apoptosis of immature and differentiated APL cells. LBH589 can eliminate C/EBPɛ and the mitochondrial apoptosis regulator B-cell lymphoma (BCL)-xL in immature and differentiated NB4 cells. Thus, BCL-xL and C/EBPɛ are newly identified molecular markers for the efficacy of HDACi against APL cells. Conclusions: Our results could explain the therapeutic limitations occurring with ATRA and class I HDACi combinations. Pro-apoptotic effects caused by pan-HDAC inhibition are not blunted by ATRA-induced differentiation and may provide a clinically interesting alternative.

Abstract
Grey seals as top-predators bioaccumulate contaminants and can be considered as sentinels of eco-system health. Pups are weaned after a short nursing period, characterised by an enormous lipid transfer and exposure to contaminants. This study established molecular biomarkers of the xenobiotic metabolism and immune system to help assess health and immune status. mRNA transcription of AHR, ARNT, PPARα and cytokine IL-2 and heat-shock-protein HSP70 was measured in blood of grey seal pups and adults in rehabilitation and permanent care using RT-qPCR and compared to rehabilitating harbour seal pups and haematology values. In pups highest levels at admission in xenobiotic biomarker, HSP70 and cytokine transcription may show contaminant exposure via lactation, stress during abandonment and dehydration. The significant decrease may be linked to diet, health improvement and adaptation. Adults showed higher levels and more variation in biomarker transcription and clear species-specific differences between harbour and grey seal pups were found.

Abstract
PURPOSE To investigate the prognosis of adenocarcinomas of the upper third of the rectum and the rectosigmoid-junction without radiotherapy. METHODS Patients from a multicenter randomized controlled trial from 1987-1993 on adjuvant chemotherapy for R0-resected colorectal cancers with stage I-III disease were retrospectively allocated: cancers of the lower two-thirds of the rectum (11 cm or less from anal-verge, Group A, n = 205), of the upper-third of the rectum and rectosigmoid-junction (>11-20 cm from anal-verge, Group B, n = 142), and of the colon (>20 cm from anal-verge, Group C, n = 378). The total mesorectal excision (TME) technique had not been introduced yet. The adjuvant chemotherapy turned out to be ineffective. None of the patients received neoadjuvant or adjuvant radiotherapy. RESULTS The patients had a regular follow-up (median, 8.0 years). The 5-year disease-free survival (DFS) rate was 0.54 (95%CI, 0.47-0.60) in Group A, 0.68 (95%CI, 0.60-0.75) in Group B, and 0.69 (95%CI, 0.64-0.74) in Group C. The 5-year overall survival (OS) rate was 0.64 (95%CI, 0.57-0.71) in Group A, 0.79 (95%CI, 0.71-0.85) in Group B, and 0.77 (95%CI, 0.73-0.81) in Group C. Compared with Group C, patients in Group A had a significantly worse OS (hazard ratio [HR] for death 2.10) and a worse DFS (HR for relapse/death 1.93), while patients in Group B had a similar OS (HR 1.12) and DFS (HR 1.07). CONCLUSIONS Adenocarcinomas of the upper third of the rectum and the rectosigmoid-junction seem to have similar prognosis as colon cancers. Even for surgeons not familiar with the TME technique, preoperative radiotherapy may be avoided for most rectosigmoid cancers above 11 cm from anal-verge.

Abstract
A 47-year-old man presented with subacute, low back pain and increased creatinine levels. A CT scan showed an extrinsic, bilateral compression of the ureters by a retroperitoneal mass with pronounced uptake of 18F-fluorodeoxyglucose in positron emission tomography. Histological findings were consistent with the diagnosis of retroperitoneal fibrosis. Urological decompression was performed. The initiated corticosteroids led to a rapid clinical improvement and regression of the retroperitoneal mass. A relapse occurred after tapering of corticosteroids with a prompt response to increase of the dosage.

Abstract
We present a method which uses Feynman-like diagrams to calculate the statistical quantities of embedded many-body random matrix problems. The method provides a promising alternative to existing techniques and offers many important simplifications. We use it here to find the fourth, sixth, and eighth moments of the level density of an m-body system with k fermions or bosons interacting through a random Hermitian potential (k ≤ m) in the limit where the number of possible single-particle states is taken to infinity. All share the same transition, starting immediately after 2k = m, from moments arising from a semicircular level density to Gaussian moments. The results also reveal a striking feature; the domain of the 2nth moment is naturally divided into n subdomains specified by the points 2k = m,3 k = m,...,nk = m.

Abstract
The β spectrum of a mass-separated thin 35S source has been measured with a small-volume Si photodiode. The energy-dependent response function of the total experimental set-up was calculated by the Monte Carlo method without any adjustable parameter. For an admixture of the hypothetical 17 keV neutrino, an upper limit of 0.59% (95% CL) was determined. Neglecting electron scattering on the spectrometer diaphragm was shown to generate a false 17 keV neutrino admixture of 0.3%.

Abstract
To determine the natural radiation exposure due to outdoor radon ((222)Rn) and its short-lived decay products in Germany, the Federal Office for Radiation Protection (BfS) conducted a measuring programme over three years. The annual mean radon concentration at 1.5 m above ground level was measured with solid-state track etch detectors at 173 measuring points in an even grid with a grid length of approx. 50 km. Furthermore, annual mean values of the equilibrium-equivalent radon concentration (EEC) and the equilibrium factor were estimated on the basis of the activity concentrations of (214)Pb and (214)Bi measured at 27 stations of the German Meteorological Service (DWD). Our study yielded a spatial mean outdoor radon concentration for Germany of 9 ± 1 Bq m(-3) (median: 8 (-0.5/+1.0) Bq m(-3)), with regional means varying from 4.5 Bq m(-3) in Hamburg to 14 Bq m(-3) in Bavaria. The determined EEC are in a range from 1.4 to 11 Bq m(-3).

Abstract
In the German Federal States of Saxony, Saxony-Anhalt and Thuringia, centuries of mining and milling activities resulted in numerous residues with increased levels of natural radioactivity such as waste rock dumps and tailings ponds. These may have altered potential radiation exposures of the population significantly. Especially waste rock dumps from old mining activities as well as 20th century uranium mining may, due to their radon ((222)Rn) exhalation capacity, lead to significant radiation exposures. They often lie close to or within residential areas. In order to study the impact on the natural radon level, the Federal Office for Radiation Protection (BfS) has run networks of radon measurement points in 16 former mining areas, together with 2 networks in regions not influenced by mining for comparison purposes. Representative overviews of the long-term outdoor radon concentrations could be established including estimates of regional background concentrations. Former mining and milling activities did not result in large-area impacts on the outdoor radon level. However, significantly increased radon concentrations were observed in close vicinity of shafts and large waste rock dumps. They are partly located in residential areas and need to be considered under radiation protection aspects. Examples are given that illustrate the consequences of the Wismut Ltd. Company's reclamation activities on the radon situation.

Abstract
AIM We aimed to investigate the histological and clinical presentations of experimental autoimmune myocarditis (EAM) induced by different immunization schemes. METHODS Male young Lewis rats were divided into five groups immunized by porcine myocardial myosin: subcutaneously (SC) 2 mg (in two 1-mg doses on day 0 and 7), 0 mg (sham group) subcutaneously into rear footpads (RF), 0.25 mg RF, 0.5 mg RF or 1 mg RF (all RF once on day 0). On day 21, left ventricular (LV) function was assessed by cardiac magnetic resonance imaging and cardiac catheterization. The type and degree of myocardial inflammatory infiltrates were determined by conventional histology and immunohistochemistry. RESULTS In the SC immunized rats and in the RF sham group, we observed 0% mortality, while in the actively RF immunized rats, mortality was 20, 20 and 44% for the 0.25 mg, 0.5 mg and 1 mg myosin doses respectively. Morbidity as defined by inflammatory infiltrates on haematoxylin and eosin (HE) staining was 22% in the SC immunized rats, 0% in the RF sham group and 100% in all actively RF immunized groups. We observed augmented relative ventricle weight and spleen weight, increased LV end-diastolic pressure, reduced LV developed pressure and reduced LV ejection fraction in all with myosin-immunized RF groups without any systematic dose effect. CONCLUSION Subcutaneous immunization to the neck and flanks did not induce a reproducible EAM, while RF myosin administration reliably led to EAM. Lower myosin doses seem to induce the complete histological and clinical picture of EAM while being associated with lower mortality, non-specific symptoms and animal distress.

Abstract
The electromagnetic dipole strength below the neutron-separation energy has been studied for the xenon isotopes with mass numbers A=124, 128, 132, and 134 in nuclear resonance fluorescence experiments using the γELBE bremsstrahlung facility at Helmholtz-Zentrum Dresden-Rossendorf and the HIγS facility at Triangle Universities Nuclear Laboratory Durham. The systematic study gained new information about the influence of the neutron excess as well as of nuclear deformation on the strength in the region of the pygmy dipole resonance. The results are compared with those obtained for the chain of molybdenum isotopes and with predictions of a random-phase approximation in a deformed basis. It turned out that the effect of nuclear deformation plays a minor role compared with the one caused by neutron excess. A global parametrization of the strength in terms of neutron and proton numbers allowed us to derive a formula capable of predicting the summed E1 strengths in the pygmy region for a wide mass range of nuclides.

Abstract
Appropriate pain therapy prior to diagnosis in patients with acute abdominal pain remains controversial. Several recent studies have demonstrated that pain therapy does not negatively influence either the diagnosis or subsequent treatment of these patients; however, current practice patterns continue to favour withholding pain medication prior to diagnosis and surgical treatment decision. A systematic review of PubMed, Web-of-Science and The-Cochrane-Library from 1929 to 2011 was carried out using the key words of 'acute', 'abdomen', 'pain', 'emergency' as well as different pain drugs in use, revealed 84 papers. The results of the literature review were incorporated into six sections to describe management of acute abdominal pain: (1) Physiology of Pain; (2) Common Aetiologies of Abdominal Pain; (3) Pre-diagnostic Analgesia; (4) Pain Therapy for Acute Abdominal Pain; (5) Analgesia for Acute Abdominal Pain in Special Patient Populations; and (6) Ethical and Medico-legal Considerations in Current Analgesia Practices. A comprehensive algorithm for analgesia for acute abdominal pain in the general adult population was developed. A review of the literature of common aetiologies and management of acute abdominal pain in the general adult population and special patient populations seen in the emergency room revealed that intravenous administration of paracetamol, dipyrone or piritramide are currently the analgesics of choice in this clinical setting. Combinations of non-opioids and opioids should be administered in patients with moderate, severe or extreme pain, adjusting the treatment on the basis of repeated pain assessment, which improves overall pain management.

Abstract
BACKGROUND The stigma of mental illness has been identified as an important barrier to treatment and recovery. Previous research reported the stigmatization of individuals with eating disorders by both health professionals and the general public. The aim of this pilot study was to empirically assess the previous stigmatization and discrimination experiences of young female patients with anorexia nervosa (AN) using a retrospective explorative approach. METHODS An in-house questionnaire that was developed to survey experiences of stigmatization was mailed to 75 former adolescent patients with AN. The mean time of assessment after discharge was 5.6 ± 1.2 years. The patients were asked to respond anonymously. The response rate was approximately 48% (n = 36). RESULTS Feelings that society held negative stereotypes of individuals with AN, concrete experiences of stigmatization and discrimination, and rejection by peers were reported. A remarkable degree of self-stigmatization, as indexed by high rates of agreement to stigmatizing statements, was detected. Approximately one third of the participants reported delayed initiation of treatment due to fear of stigmatization and discrimination. CONCLUSION Stigmatization plays a decisive role in young patients with AN and impacts their motivation to seek professional help and engage in treatment. Clinicians should be aware of the stigmatization related to eating disorders and its burden for affected patients.
