Pseudomonas cellulosa is a highly efficient xylan-degrading bacterium. Genes encoding five xylanases, and several accessory enzymes, which remove the various side chains that decorate the xylan backbone, have been isolated from the pseudomonad and characterized. The xylanase genes consist of xyn10A, xyn10B, xyn10C, xyn10D, and xyn11A, which encode Xyn10A, Xyn10B, Xyn10C, Xyn10D, and Xyn11A, res...

In this paper, we present the VI-CCD photometry of 11 unstudied clusters located in the bar of the Large Magellanic Cloud (LMC), as a part of a project aimed to infer the star formation history of this galaxy. We derive the ages of these clusters by means of isochrone fitting. Three close pairs of clusters are included in the sample, namely NGC 1903-SL 357, SL 349SL 353, SL 387-SL 385. We discu...

The data about the safety of vaginal birth after caesarean section are conflicting. This study in a referral hospital in Sana'a, Yemen investigated the outcome of vaginal birth after caesarean section in 357 women who had one prior caesarean section and were admitted to hospital at term with spontaneous onset of labour. A control group (n = 155) was matched from women without previous caesarean...
