A polynucleotide phosphorylase with a molecular weight of 100,000 has been isolated from Escherichia coli Q13 mutant and partially purified. This mutant is particularly rich in this low molecular species which can, however, also be found in small proportion in wild strains of E. coli B and K12...
EnterococcusBackground: Infectious diseases produced by Enterococcus spp, must be treated with a synergistic combination between a penicillin and an aminoglycoside. High level resistance to aminoglycosides is a serious therapeutic problem, since it predicts the loss of synergistic activity of this ...

To explain this evolution of music, we study the emergence of sound - which has no affinities with timbre - in contemporary music (1950-60) and more precisely, in the first works of Xenakis. We begin with the fact that the traditional categories of tone, rhythm, language and form are ...
Purpose To study the success rate of combined phaco-intraocular lens (IOL)-deep sclerectomy (P-DS), a new perforating filtering surgery, versus phaco-IOL-trabeculectomy (P-T).Methods Of 38 patients, 39 eyes with cataract and different types of glaucoma, 19 eyes underwent P-DS, and 20 ...
