Abstract. This paper introduces the aims and early activities of Colour and Space in Cultural Heritage (COSCH), an interdisciplinary European network of experts in the latest optical measuring techniques and electronic imaging applied to documentation of artefacts. COSCH is a forum open to organisations, institutions and companies interested in collaboration within the emerging field of precise spectral and spatial imaging techniques, in physical and chemical sciences applied to cultural heritage objects, as well as in research and applications to conservation and art-historical analysis of such objects. COSCH started in November 2012. Funded by COST, an intergovernmental framework for European Cooperation in Science and Technology, COSCH networking activities enable knowledge exchange and coordination of nationally-funded research on a European level with occasional contribution of experts from other countries. Funding has been made available for four years (2012–2016). Participation is open to researchers across a wide range of disciplines, including computer scientists and museum professionals, art historians and academics in heritage-related fields. COSCH is a trans-domain Action (TD1201) of the COST Domain Materials, Physics and Nanosciences (MPNS) which facilitates and promotes innovation in material science. The work of COSCH is defined in the Memorandum of Understanding between the COST Office and the Chairman of COSCH. The Memorandum is available from http://www.cost.eu/domains_actions/mpns/Actions/TD1201 alongside the latest progress report and other documents. The scientific work draws on earlier and current research of the participants and is organised around the following areas: spectral and spatial object documentation; algorithms and procedures; analysis and restoration of surfaces and objects of material culture; visualisation of cultural heritage objects and its dissemination. Up-to-date information about COSCH activities, including its scientific and training programmes, abstracts of presentations and a list of participants, can all be found on the Action website at http://www.cosch.info.

We present a new approach to quantifying pole parameters of single-channel processes based on a Laurent expansion of partial-wave T-matrices in the vicinity of the real axis. Instead of using the conventional power-series description of the non-singular part of the Laurent expansion, we represent this part by a convergent series of Pietarinen functions. As the analytic structure of the non-singular part is usually very well known (physical cuts with branch points at inelastic thresholds, and unphysical cuts in the negative energy plane), we find that one Pietarinen series per cut represents the analytic structure fairly reliably. The number of terms in each Pietarinen series is determined by the quality of the fit. The method is tested in two ways: on a toy model constructed from two known poles, various background terms, and two physical cuts, and on several ∞

A candidate identification questionnaire (CIQ) was tested to determine its predictive value for patient-reported satisfaction in patients switched from once-weekly or once-daily treatment with a bisphosphonate to once-monthly dosing. This was a prospective, open-label, multicenter international study in patients with postmenopausal osteoporosis who had been receiving once-daily or once-weekly alendronate or risendronate for at least 3 months. Patients completed a CIQ, then commenced 150 mg monthly ibandronate for 6 months. Patients completed the Osteoporosis Patient Satisfaction Questionnaire (OPSAT-QTM) at baseline for 6 months. Scores were converted to composite satisfaction scores (CSS, scale 0-100). Totally 677 patients completed a CIQ, 645 were enrolled in the treatment phase and comprised the intent-to-treat (ITT) population, and 630 completed the study. In the ITT population, 68.1% patients answered “yes” to one or more CIQ questions. OPSAT-Q scores increased for the convenience, quality of life and overall satisfaction domains (p scores for the side effects domains were significant (p preferred the once-monthly dosing schedule and 563 patients (90.7%) found it more convenient. The most common adverse events were dyspepsia (1.9%), nausea (1.1%), and upper abdominal pain (0.9%). Patients are likely to prefer treatment with monthly ibandronate to a weekly or monthly bisphosphonate irrespective of their stated preference before switching treatment.

The division of responsibilities in complex states is a difficult issue. Of how these divisions depend on the organization of state administration at all levels of government. As Bosnia and Herzegovina is a complex state and thus its administration is very complex and diversified. Hence, Bosnia and Herzegovina has a large number of government agencies and organizations at all levels of government. Between these agencies and organizations, there is a relationship of cooperation and relations of mutual rights and obligations. Therefore, there is no hierarchical relationship except in the civil administration of the Republic of Srpska. The paper analyzes the status of state administration at all levels of government with regard to key administrative institutions.

Introduction: Psoriasis is a chronic inflammatory skin disease that affects about 2% of general population. Clinically, disease can present with cutaneous and nails lesions. Nail abnormalities can be seen in up to two-thirds of patients with psoriasis and both fingernails and toenails may be affected. Objective: The objectives of our study were to evaluate the frequency and clinical presentations of nail abnormalities in patients with psoriasis. Also, we aimed to find correlation between nail changes and some clinical parameters. Methods: One hundred and ten patients with psoriasis were included in this study. A detailed history and examination was recorded for all study subjects, including the age and gender of the patients, type of psoriasis, duration, and extent of disease. Finger and toe nails were clinically examined and nail changes were noted. In the case of clinically suspected of fungal infection, further mycological investigations were performed. Results: Nail abnormalities were present in 67 patients (60.9%) with psoriasis. Nail pitting was the most common lesion observed on fingernails, followed by discoloration of nail plate. Subungual hyperkeratosis of nail plates were significantly more frequent on the toenails. Positive mycological culture was in 14 (20.8%) psoriatic patients with nail involvement. Also, positive correlation between nail abnormalities and duration of psoriasis was found. Conclusions: Nail involvement is common in patients with psoriasis and accompanies skin lesions on the body surface. Pitting and subungual hyperkeratosis are the most frequent nail abnormality in psoriatic patients.

Background: Chemokines play a prominent role in inflammatory diseases. Results: Nanobodies targeting chemokines display high affinity and potently neutralize chemokine-induced receptor binding and signaling. Conclusion: Neutralizing Nanobodies targeting chemokines effectively inhibit chemokine function. Significance: Nanobodies directed against inflammatory and homeostatic chemokines form a promising new class of potent and specific inhibitors of chemokine function, to be used for research and therapeutic purposes. Chemokine receptors and their ligands play a prominent role in immune regulation but many have also been implicated in inflammatory diseases such as multiple sclerosis, rheumatoid arthritis, allograft rejection after transplantation, and also in cancer metastasis. Most approaches to therapeutically target the chemokine system involve targeting of chemokine receptors with low molecular weight antagonists. Here we describe the selection and characterization of an unprecedented large and diverse panel of neutralizing Nanobodies (single domain camelid antibodies fragment) directed against several chemokines. We show that the Nanobodies directed against CCL2 (MCP-1), CCL5 (RANTES), CXCL11 (I-TAC), and CXCL12 (SDF-1α) bind the chemokines with high affinity (at nanomolar concentration), thereby blocking receptor binding, inhibiting chemokine-induced receptor activation as well as chemotaxis. Together, we show that neutralizing Nanobodies can be selected efficiently for effective and specific therapeutic treatment against a wide range of immune and inflammatory diseases.

An investigation of the structures and chemistry of substituted hexamethyl disiloxanes ((XCH2)3Si)2O; X=F, Cl, Br, I, N3 , and ONO2) is reported. New synthetic routes to the precursor hexakis(chloromethyl)disiloxane are presented. The products with X=Cl, Br, I, and N3 were characterized by NMR, IR, and Raman spectroscopy. In addition, the single-crystal structures of the products with X=Cl, Br, and I are discussed in detail. The compounds with X=F and ONO2 were not obtained in their pure form; instead investigations of the decomposition products revealed their conversion into intermediates. Theoretical calculations of the gas-phase structures at the B3LYP/cc-pVDZ, B3LYP/3-21G, MP2/6-31G*, and MP2/3-21G levels of theory are used to explain the chemical and physical behavior of the compounds with X=Cl, Br, I, N3, and ONO2. A new decomposition pathway of hexakis(nitratomethyl)disiloxane is presented and is used to explain their remarkable instability. The energetic properties and values of the nitrate and azide derivatives were calculated at the CBS-4M level of theory by using the improved EXPLO5 computer code version 6.01.
