Abstract
BACKGROUND Interleukin (IL) 37 has been described as a negative regulator of innate immunity, as it reduces the activation and cytokine production of different innate immune cells. Recently, results from the CLARA childhood asthma cohort suggested an implication of IL-37 for human asthma pathogenesis. This study aimed to investigate the effects of IL-37 on allergic airway inflammation in a mouse model of experimental asthma. METHODS Peripheral blood mononuclear cells (PBMCs) of children were cultured for 48 h (anti-CD3/anti-CD28 stimulation or unstimulated), and IL-37 concentrations in supernatants were determined. Wild-type, IL-18Rα-deficient ((-/-) ), and SIGIRR(-/-) C57BL/6 mice were sensitized to ovalbumin (OVA) and challenged with OVA aerosol to induce acute experimental asthma, and IL-37 was applied intranasally prior to each OVA challenge. Airway hyper-responsiveness (AHR), airway inflammation, cytokine levels in broncho-alveolar lavage fluid, and mucus production were determined. RESULTS IL-37 production of human PBMCs was significantly lower in allergic asthmatics vs healthy children. In wild-type mice, intranasal administration of IL-37 ablated allergic airway inflammation as well as cytokine production and subsequently diminished the hallmarks of experimental asthma including mucus hyperproduction and AHR. In contrast, local application of IL-37 produced none of these effects in mice lacking either IL18Rα or SIGIRR/IL-1R8. CONCLUSIONS This study demonstrates that IL-37 is able to ablate a TH2 cell-directed allergic inflammatory response and the hallmarks of experimental asthma in mice, suggesting that IL-37 may be critical for asthma pathogenesis. Furthermore, these data suggest a mode of action of IL-37 that involves IL18Rα as well as the orphan receptor SIGIRR/IL-1R8.

Abstract
BACKGROUND AND PURPOSE To investigate resource use and burden associated with spina bifida (SB) in Germany. METHODS A questionnaire was used to obtain information on SB-related healthcare resource use and assistive technologies used for the last 1 and 10 years. Individuals with SB were recruited at a tertiary specialist clinic. To participate, persons with SB required the cognitive ability to respond or a caregiver to answer questions on their behalf. They could use personal medical charts or other records to answer. The analyses included assessment of frequency and extent of resource use for both time frames. RESULTS Data on 88 persons with a diagnosis of SB were collected (44% female). During the last year, 88.6% (N = 78) reported at least one visit to a general practitioner's (GP's) office, 77.3% (N = 68) to a urologist and 69.3% (N = 61) to a physiotherapist. The annual average number of visits was 7.6 GP, 3.6 urologist and 65.3 physiotherapist visits. Amongst those hospitalized, a single hospitalization lasted 7.3 days on average, whereas the average annual number of hospital days was 14.8 days. During the previous 10 years, 67.0% (N = 59) of responders used a wheelchair, 64.7% (N = 57) used glasses and 59.1% (N = 52) used orthopaedic shoes, with an average of 2.5, 2.8 and 6.1 new items used, respectively. CONCLUSIONS The results indicate that persons with SB require a substantial amount of interaction with healthcare providers, as well as other healthcare-related resource use, both in the shorter and longer terms.

Abstract
Despite advances in allogeneic stem cell transplantation, BCR-ABL-positive acute lymphoblastic leukaemia (ALL) remains a high-risk disease, necessitating the development of novel treatment strategies. As the known oncomir, miR-17~92, is regulated by BCR-ABL fusion in chronic myeloid leukaemia, we investigated its role in BCR-ABL translocated ALL. miR-17~92-encoded miRNAs were significantly less abundant in BCR-ABL-positive as compared to -negative ALL-cells and overexpression of miR-17~19b triggered apoptosis in a BCR-ABL-dependent manner. Stable isotope labelling of amino acids in culture (SILAC) followed by liquid chromatography and mass spectroscopy (LC-MS) identified several apoptosis-related proteins including Bcl2 as potential targets of miR-17~19b. We validated Bcl2 as a direct target of this miRNA cluster in mice and humans, and, similar to miR-17~19b overexpression, Bcl2-specific RNAi strongly induced apoptosis in BCR-ABL-positive cells. Furthermore, BCR-ABL-positive human ALL cell lines were more sensitive to pharmacological BCL2 inhibition than negative ones. Finally, in a xenograft model using patient-derived leukaemic blasts, real-time, in vivo imaging confirmed pharmacological inhibition of BCL2 as a new therapeutic strategy in BCR-ABL-positive ALL. These data demonstrate the role of miR-17~92 in regulation of apoptosis, and identify BCL2 as a therapeutic target of particular relevance in BCR-ABL-positive ALL.

Abstract
According to present knowledge, blood derived endothelial progenitor cells (EPC) might act as proangiogenic myeloid cells, which play a fundamental role in the regulation of angiogenesis and blood vessel reorganisation. In this context, we have evaluated the contribution of endogenous myeloid cells in co-cultures of blood derived outgrowth endothelial cells (OEC) and osteogenic cells. In addition, we investigated the role of EPC as a potential source of myeloid cells in the formation of vascular structures in an in vitro model consisting of mesenchymal stem cells (MSC) and OEC. For this purpose, we added EPCs to co-cultures of MSC and OECs. Vascular structures and the co-localisation of myeloid cells were analysed by confocal laser microscopy (CLSM) for endothelial and myeloid markers and quantitative image analysis. The molecular effects of myeloid cells were evaluated by quantitative real time PCR, ELISA and protein arrays from cell culture supernatants and lysates. Endogenous myeloid cells were significantly co-localised with angiogenic structures in co-cultures of OEC and osteogenic cells. The active addition of EPC to co-cultures of OEC and MSC resulted in a statistically approved increase in the formation of prevascular structures at early stages of the co-culture process. In addition, we observed an increase of endothelial markers, indicating beneficial effects of EPC or myeloid cells on endothelial cell growth. Furthermore, real time PCR indicated high expression levels of CD68, CD11b and CD163 in co-cultures of EPC and MSC indicating that EPC act at least partly as macrophage like-cells.

Abstract
The influence of demographic characteristics on patients' ratings of the quality of psychiatric outpatient care has been given little attention in research. The aim of the present study is to elucidate the quality of psychiatric care among outpatients and investigate demographic and clinical factors associated with the way in which this quality is perceived. A sample of 1340 outpatients from 15 general adult psychiatric clinics in Sweden completed the quality in psychiatric care-out-patient (QPC-OP), with a response rate of 71%. The patients' highest ratings were for Encounter; the lowest were for discharge. Most notably, quality of care was rated higher by women, older people, those with a partner, those with a lower educational level and those who were gainfully employed. In regard to visits to the clinic, higher quality of care was associated with shorter waiting time, better information and fewer professions encounters. Older people and those gainfully employed reported better mental health. Thus the QPC-OP was associated with both demographic and clinical factors. In particular, 'wanting to come back to the clinic' was the single strongest predictor of quality.

Abstract
The binding of cationic surfactants with varying alkyl chain length to a regiorandom conjugated polyanion, poly(3-thiophene acetic acid) (PTAA), is studied in an aqueous buffer by using absorption and emission spectroscopies, photon correlation spectroscopy, isothermal titration calorimetry, and cryogenic transmission electron microscopy. We study the mixed solutions as a function of composition ratio R of surfactant molecules to monomer units molar concentrations, at low polymer concentration and in a very wide composition range (10(-6) < R < 10(2)) below the critical micellar concentration. Upon surfactant binding, the molecularly dispersed chains first collapse progressively and then form new structures as the mixed aggregates get enriched in surfactant. The collapse leads to a strong decrease of the conjugation length and to a blue shift of the absorption spectra by 30 to 50 nm. The new structures are responsible for a new intense emission band at about 600 nm, red-shifted by nearly 130 nm from the initial emission maximum of the polymer (~472 nm). As the surfactant tail becomes shorter, the blue shift of the absorption spectra and the intensity raise of the new emission are delayed to larger composition ratios while their variations become smoother functions of the surfactant concentration. These particular spectroscopic properties of PTAA seem related to its unique combination of a strongly hydrophobic backbone, a large ratio of contour length to persistence length, and an overall good aqueous solubility. Our results show that such features are well suited to design a colorimetric biosensor at small composition ratio, and a fluorescent biomarker at large composition ratio.

Abstract
CONTEXT The first European Association of Urology (EAU) guidelines on incontinence were published in 2001. These guidelines were periodically updated in past years. OBJECTIVE The aim of this paper is to present a summary of the 2009 update of the EAU guidelines on urinary incontinence (UI). EVIDENCE ACQUISITION The EAU working panel was part of the 4th International Consultation on Incontinence (ICI) and, with permission of the ICI, extracted the relevant data. The methodology of the 4th ICI was a comprehensive literature review by international experts and consensus formation. In addition, level of evidence was rated according to a modified Oxford system and grades of recommendation were given accordingly. EVIDENCE SUMMARY A full version of the EAU guidelines on urinary incontinence is available as a printed document (extended and short form) and as a CD-ROM from the EAU office or online from the EAU Web site (http://www.uroweb.org/guidelines/online-guidelines/). The extent and invasiveness of assessment of UI depends on severity and/or complexity of symptoms and clinical signs and is different for men, women, frail older persons, children, and patients with neuropathy. At the level of initial management, basic diagnostic tests are applied to exclude an underlying disease or condition such as urinary tract infection. Treatment is mostly conservative (lifestyle interventions, physiotherapy, physical therapy, pharmacotherapy) and is of an empirical nature. At the level of specialised management (when primary therapy failed, diagnosis is unclear, or symptoms and/or signs are complex/severe),more elaborate assessment is generally required, including imaging, endoscopy, and urodynamics. Treatment options include invasive interventions and surgery. CONCLUSIONS Treatment options for UI are rapidly expanding. These EAU guidelines provide ratings of the evidence (guided by evidence-based medicine) and graded recommendations for the appropriate assessment and according treatment options and put them into clinical perspective.

Abstract
Chromatin-remodeling complexes regulate the expression of genes in all eukaryotic genomes. The SWI/SNF complex of Saccharomyces cerevisiae is recruited to its target promoters via interactions with selected transcription factors. Here, we show that the N-terminus of Snf2p, the chromatin remodeling core unit of the SWI/SNF complex, is essential for the expression of VHT1, the gene of the plasma membrane H+/biotin symporter, and of BIO5, the gene of a 7-keto-8-aminopelargonic acid transporter, biotin biosynthetic precursor. chromatin immunoprecipitation (ChIP) analyses demonstrate that Vhr1p, the transcriptional regulator of VHT1 and BIO5 expression, is responsible for the targeting of Snf2p to the VHT1 promoter at low biotin. We identified an Snf2p mutant, Snf2p-R15C, that specifically abolishes the induction of VHT1 and BIO5 but not of other Snf2p-regulated genes, such as GAL1, SUC2 or INO1. We present a novel mechanism of target gene-specific SWI/SNF recruitment via Vhr1p and a conserved N-terminal Snf2p domain.

Abstract
In this study, we present a method for the three-dimensional reconstruction of objects obtained from histological serial sections (exemplified by those of a pennate striated skeletal muscle) and its application to the finite element method. A hyperelastic material model is used for modeling biological soft tissue. The reconstruction process relies on the direct construction of a volumetric mesh using an octree approach which leads to a stable finite element method. Stability can be expressed in the spectral matrix condition number. To visualize stress patterns within the underlying anatomy the simulation results are projected onto images of the histological scenario.
