Aims: We have provided evidence in former studies that cytokines (IL-8, TNF alpha, LBP, TGFß) measured in blood correlate negatively with lung function in deltaF508 homozygous patients. GAP junction proteins might be of importance for the influx of blood cells into the lung. Our aim was to assess the relationship between connexin genotypes and cytokines (IL-8, TNF-alpha, LBP, TGFß) in induced sputum and serum, and lung disease.
Methods: 36 patients homozygous for deltaF508 (median age 18 y, m/f 16/20, FEV1(%) 77) were examined. Sequence analysis was performed for genes encoding GAP junction protein alpha 1 (GJA1/connexin 43) and gap junction protein alpha 4 (GJA4/connexin 37). Cytokines were assessed in serum and induced sputum (IS) by chemiluminescence (DPC Biermann, Bad Homburg, Germany) as well as leukocyte counts.
Results: DNA analysis was performed in 35 patients. Whereas GJA1 showed only one rare heterozygous synonymous SNP (rs138386744) in one patient, four common SNPs were detected in GJA4. Two were synonymous changes, but the third variant (rs41266431) predicts an amino acid substitution (GTA → valine, ATA → isoleucine) as well as the fourth SNP (rs1764391: CCC→proline, TCC→serine). For rs41266431 patients with homozygosity for the G variant had higher IL-8 levels (median: 13.3/8.0 pg/ml, p=0.07) in serum as well as leukocytes in sputum (median: 2050/421 /µl p=0.041) than those showing heterozygosity (G/A). In individuals > 30 years lung function (FEV1 41.3/84.83 % predicted, p=0.07) was worse.
Conclusion: SNP rs41266431 seems a promising candidate for further investigations, suggesting GJA4 a potential disease modifying gene.
We have studied one-proton-removal reactions of about 500MeV/u 17Ne beams on a carbon target at the R3B/LAND setup at GSI by detecting beam-like 15O-p and determining their relative-energy distribution. We exclusively selected the removal of a 17Ne halo proton, and the Glauber-model analysis of the 16F momentum distribution resulted in an s2 contribution in the 17Ne ground state of about 40%.
We present the results of two-pion production in tagged quasi-free np collisions at a deutron incident beam energy of 1.25 GeV/c measured with the High-Acceptance Di-Electron Spectrometer (HADES) installed at GSI. The specific acceptance of HADES allowed for the first time to obtain high-precision data on π+π− and π−π0 production in np collisions in a region corresponding to large transverse momenta of the secondary particles. The obtained differential cross section data provide strong constraints on the production mechanisms and on the various baryon resonance contributions (∆∆, N(1440), N(1520), ∆(1600)). The invariant mass and angular distributions from the np → npπ+π −and np → ppπ−π0 reactions are compared with different theoretical model predictions.
Cultural heritage reconstructed - Compact Memory and the Frankfurt Digital Judaica Collection
(2014)
Compact Memory, the internet archive of German Jewish periodicals, provides free global internet access to the vast majority of German-Jewish newspapers and periodicals of the 19th and 20th century.
Jewish historical newspapers are the invaluable sources that supply direct and detailed information of the transformation process of Jewry and offer new insights into European Jewish history. The use of these historical sources however is extremely difficult, as complete sets of periodicals are very rarely to be found and they are scattered all over the world in different libraries and archives and in different physical formats (paper, microfilm).
Compact Memory contains the 110 most important Jewish German newspapers and periodicals in Central Europe in the period from 1806-1938, covering the complete range of religious, political, social, cultural and academic aspects of Jewish life. The texts are available partly as full-texts, processed by OCR, partly as graphic documents with corresponding index options. The database offers advanced search options, downloading and printing of articles. Thousands of essays of more than 10.000 individual contributors have been bibliographically indexed.
Compact Memory was established by the Judaica Division of the University Library Frankfurt am Main and in charge today in cooperation with the Aachen Chair of German-Jewish Literary History and the Cologne library Germania Judaica.
Compact Memory is one database within the Digital Collection Judaica which being part of Europeana and other digital portals offers resources for the reconstruction and representation of Jewish cultural heritage.
