DKK1 is found elevated in serum from patients affected with various types of cancers and in some instances, it is considered a diagnostic and prognostic biomarker. Elevated serum levels of DKK1 have also been detected in animal models of chronic inflammatory diseases. Previous work from our laboratory has demonstrated upregulation of DKK1 in cells and mouse models of the bone marrow failure (BMF) and cancer-prone disease Fanconi anemia (FA). The present study aimed to investigate whether DKK1 blood levels in patients are associated with FA or inflammatory responses to acute infections. Methods Plasma samples were collected from 58 children admitted to the Centre M{\`e}re-Enfant Soleil du Centre Hospitalier de Qu{\´e}bec-Universit{\´e} Laval with signs of acute infections. Blood plasma specimens were also collected from healthy blood donors at the H{\´e}ma-Qu{\´e}bec blood donor clinic. Plasmas from patients diagnosed with FA were also included in the study. DKK1 levels in blood plasmas were assessed by standard ELISA. Results Patients with acute infections showed dramatically high levels of DKK1 (6072 ± 518 pg/ml) in their blood compared to healthy blood donors (1726 ± 95 pg/ml). No correlations were found between DKK1 levels and C reactive protein (CRP) concentration, platelet numbers, or white blood cell counts. Patients with FA showed higher DKK1 plasma levels (3419 ± 147.5 pg/ml) than healthy blood donors (1726 ± 95 pg/ml) but significantly lower than patients with acute infections. Conclusion These findings suggest that blood DKK1 is elevated in response to infections and perhaps to inflammatory responses.}, language = {en} } @article{VanAsscheFicklFranciscoetal.2018, author = {Van Assche, Nele and Fickl, Stefan and Francisco, Helena and Gurzawska, Katarzyna and Milinkovic, Iva and Navarro, Jose M. and Torsello, Ferruccio and Thoma, Daniel S.}, title = {Guidelines for development of Implant Dentistry in the next 10 years regarding innovation, education, certification, and associations}, series = {Clinical Oral Implants Research}, volume = {29}, journal = {Clinical Oral Implants Research}, doi = {10.1111/clr.13154}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-232150}, pages = {568-575}, year = {2018}, abstract = {Background During the third Summer Camp of European Association of Osseointegration (EAO), 40 junior representatives from various European societies and associations were brought together to discuss and explore the following topics in Implant Dentistry in the next 10 years: (I) certification, (II) societies and associations, (III) continuing education, and (IV) innovations. Aims The aims of all working groups were to identify and outline the present situation in the area of the selected topic and to propose improvements and innovations to be implemented in the following 10 years. Materials and methods Four different groups were assigned randomly to one of the four working units. The method to discuss the selected topics was World Caf{\`e}. The summaries of four topics were then given to all participants for peer review. Results and conclusions All four groups presented the conclusions and guidelines accordingly: (I) The recognition for Implant Dentistry and accreditation of training programs would lead to an improvement of the quality of care to the benefit of the patients; (II) Dental associations and societies have to continuously improve communication to meet needs of dental students, professionals, and patients (III) European Dental Board should be installed and become responsible for continue dental education; (IV) dental engineering, peri-implant diseases, and digital workflow in dentistry currently have limited tools that do not guarantee predictable results.}, language = {en} } @article{OPUS4-31382, title = {Dijet azimuthal correlations and conditional yields in \({pp}\) and \(p\) + Pb collisions at √S-NN=5.02 TeV with the ATLAS detector}, series = {Physical Review C}, volume = {100}, journal = {Physical Review C}, number = {3}, organization = {The ATLAS Collaboration}, doi = {10.1103/PhysRevC.100.034903}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-313823}, pages = {1-24}, year = {2019}, abstract = {This paper presents a measurement of forward-forward and forward-central dijet azimuthal angular correlations and conditional yields in proton-proton (pp) and proton-lead (p + Pb) collisions as a probe of the nuclear gluon density in regions where the fraction of the average momentum per nucleon carried by the parton entering the hard scattering is low. In these regions, gluon saturation can modify the rapidly increasing parton distribution function of the gluon. The analysis utilizes 25 pb(-1) of pp data and 360 mu b(-1) of p + Pb data, both at root S-NN = 5.02 TeV, collected in 2015 and 2016, respectively, with the ATLAS detector at the Large Hadron Collider. The measurement is performed in the center-of-mass frame of the nucleon-nucleon system in the rapidity range between -4.0 and 4.0 using the two highest transverse-momentum jets in each event, with the highest transverse-momentum jet restricted to the forward rapidity range. No significant broadening of azimuthal angular correlations is observed for forward-forward or forward-central dijets in p + Pb compared to pp collisions. For forward-forward jet pairs in the proton-going direction, the ratio of conditional yields in p + Pb collisions to those in pp collisions is suppressed by approximately 20\%, with no significant dependence on the transverse momentum of the dijet system. No modification of conditional yields is observed for forward-central dijets.}, language = {en} }
