The primordial germ cells (PGCs) in the oligochaete annelid Tubifex tubifex are descentants of the mesodermal (M) teloblast and are located in the two midbody segments X and XI in which they serve as germline precursors forming the testicular gonad and the ovarian gonad, respectively. During embryogenesis, vasa-expressing cells (termed presumptive PGCs or pre-PGCs) emerge in a variable set of m...
Suomi NPP VIIRS SWIR band M11 (2.25 μm) has larger radiometric uncertainty compared to the rest of the reflective solar bands. This is due to a number of reasons including prelaunch calibration uncertainties. One of the most commonly used technique to verify the radiometric stability and accuracy of VIIRS is by intercomparing it with other well calibrated radiometers such as MODIS. However one ...
ABSTRACT We have developed a new method for spectral analysis of binaries. Our successfully identifies double-lined spectroscopic binary (SB2) candidates from high-resolution Gaia-ESO spectra. Compared to the commonly used cross-correlation function analysis, it works binaries with rapidly rotating components. test our on synthetic and observational spectra BAFG stars vsin i 1 $330~\, {\rm km}\...
The gammaherpesviruses are characteristically latent in lymphocytes and exploit lymphocyte proliferation to establish a large, persistent pool of latent genomes. Murine gammaherpesvirus 68 (MHV-68) allows the in vivo analysis of viral genes that contribute to this and other aspects of host colonization. In this study, the MHV-68 bcl-2 homologue, M11, was disrupted either in its BH1 homology dom...
In the last decade, numerous microRNAs (miRNAs) have been identified in diverse virus families, particularly in herpesviruses. Gallid alphaherpesvirus 2 (GaHV2) is a representative oncogenic alphaherpesvirus that induces rapid-onset T-cell lymphomas in its natural hosts, namely Marek's disease (MD). In the GaHV2 genome there are 26 mature miRNAs derived from 14 precursors assembled into three c...
خوشه های ستاره ای اطلاعاتی راجع به آغاز، حال حاضر و آینده ی جهان هستی بدست میدهند. خوشه های باز ستاره ای با داشتن ستاره های جوان، امکان مطالعه ی توزیع جرم ستاره ها در صفحه کهکشان راه شیری را فراهم می سازند. با ارائه ی توصیف کلی درباره ی خصوصیات ساختاری خوشه ی باز ستاره ای و سیر تحولی ستاره های عضو خوشه، اطلاعات لازم برای مطالعه ی منحنی های همسن خوشه بدست می آید. این حقیقت که منحنی های همسن محاس...
The primary attachment to polymer surfaces followed by accumulation in multilayered cell clusters leads to production of Staphylococcus epidermidis biofilms, which are thought to contribute to virulence in biomaterial-related infections. We isolated Tn917 transposon mutants of biofilm-producing S. epidermidis 13-1, which were completely biofilm negative. In pulsed-field gel electrophoresis no o...
