Two studies determined the accuracy of glenoid bone loss measuring methods performed on X-ray by comparing them to methods performed on 3D-CT. Six studies determined the accuracy of methods performed on imaging modalities with an arthroscopy method as reference. Eight studies reported on the influence of imaging modality on the accuracy of the methods. There was no consensus regarding gold standard. Due to the heterogeneity of the data, a quantitative analyses was not feasible. CONCLUSION Consensus with regard to gold standard in measuring glenoid bone loss is lacking. The use of heterogeneous data and varying methods contributes to differences in gold standard and accuracy can therefore not be determined. Three types of intracytoplasmic inclusions immunoreactive to fibrinogen are collectively diagnosed as hepatic fibrinogen storage disease. This study aimed to better characterize ground glass (type II) and globular (type III) fibrinogen inclusions by the pathological examination of 3 cases and a literature review. Onametostat in vitro Three adults (age 32-64 years; M/F 2/1) were unexpectedly found by liver needle biopsy to have fibrinogen-positive ground glass changes (type II inclusions), against a background of acute hepatitis E, resolving acute cholangitis, or severe lobular hepatitis of unknown etiology. One patient also had fibrinogen-positive intracytoplasmic globules (type III inclusions) in the first biopsy, but they were not present in a second biopsy. None had coagulation abnormalities or hypofibrinogenemia. On immunostaining, both inclusions were strongly positive for not only fibrinogen but also C-reactive protein and C4d. Ultrastructurally, ground glass changes corresponded to membrane-bound cytoplasmic inclusions containing amorphous, granular material. The pathological features of type II fibrinogen inclusions were identical to those of pale bodies in hepatocellular carcinoma. The literature review suggested that type I fibrinogen inclusions characterized by a polygonal appearance are strongly associated with mutations in fibrinogen genes, coagulopathy, and family history, whereas type II/III inclusions are immunoreactive to multiple proteins and typically develop in cases of other unrelated liver diseases. In conclusion, type II and III fibrinogen inclusions do not represent a true hereditary storage disease but instead the collective retention of multiple proteins. Given the lack of clinical significance, a less specific name (e.g., pale body) may be more appropriate for those inclusions. Natural evolution has generated an impressively diverse protein universe via duplication and recombination from a set of protein fragments that served as building blocks. The application of these concepts to the design of new proteins using subdomain-sized fragments from different folds has proven to be experimentally successful. To better understand how evolution has shaped our protein universe, we performed an all-against-all comparison of protein domains representing all naturally existing folds and identified conserved homologous protein fragments. Overall, we found more than 1000 protein fragments of various lengths among different folds through similarity network analysis. These fragments are present in very different protein environments and represent versatile building blocks for protein design. This data is available in our web server called F(old P)uzzle (fuzzle.uni-bayreuth.de), which allows to individually filter the dataset and create customized networks for folds of interest. We believe that our results serve as an invaluable resource for structural and evolutionary biologists and as raw material for the design of custom-made proteins. Foxp3+ Regulatory T cells (Tregs) are essential for the maintenance of tolerance to self. Therefore, it is expected that lower numbers and/or less than optimal function could impact on the functioning of the immune system, and thereby contributing to the development of autoimmune diseases. In the present report, by comparing Tregs from most frequently used mouse strains in immunological research (C57BL/6 (B6), BALB/c and NOD), we provide evidence showing that the NOD mouse strain, highly predisposed to develop autoimmune responses, exhibit a generalized decreased in Tregs counts with enhanced proportions of CD44hiCD62Llow Tregs when compared with BALB/c mice. No major differences were observed in Helios+ or Helios- Tregs between strains. The expression of CXCR3, CCR5 and CCR6 on Tregs from all strains showed minor proportions of CXCR3+ and CCR5+ cells in NOD Tregs. Naïve CD4+CD25- T cells from NOD mice also showed decreased capacity to induce in vitro iTregs when compared with B6 and BALB/c mice. Lower expresedisposition to develop spontaneous and induced autoimmune diseases. V.Endothelial dysfunction (ED) plays a key role in developing of cardiovascular diseases and is an important predictor of future cardiovascular events. Nevertheless, there is no established method assessing endothelial function in general population. The most popular protocol includes the ultrasound-flow-mediated-dilation, but its repeatability is operator-dependent. We intended to compare the two other operator-independent methods assessing endothelial function - the EndoPAT and Laser Doppler flowmetry (LD), and we endeavored to place them on current individual profile of biochemical cardiovascular risk and endothelial function. A total of 61 clinically healthy subjects (aged 29 ± 1y) were investigated. The blood was collected for conventional cardiovascular risk markers, the NO-pathway metabolites (ADMA, L-arginine, SDMA), oxidative-stress-markers (MDA, thiol-index) as well as endothelial and platelet activation markers (sICAM1, sVCAM1, PAI-1, sE-selectin, sP-selectin, VEGF). Subsequently, all participants underwent examination by both EndoPAT and LD. There was a poor correlation between EndoPAT and LD results. No significant differences between participants with preserved and impaired endothelial function regarding endothelial activation nor cardiovascular risk markers were observed. Both methods assess endothelial function independently from the profile of endothelial pro/anti-inflammatory status and conventional risk factors, therefore further prospective studies are needed in order to verify their additional value in the cardiovascular risk stratification.
