[This corrects the article on p. 211 in vol. 6, PMID: 24175086.].
DNA and RNA polymerases use a common phosphoryl transfer mechanism for base addition that requires two or three acidic amino acid residues at their active sites. We previously showed, for the reverse transcriptase (RT) encoded by the yeast retrotransposon Ty1, that one of the three conserved active site aspartates (D(211)) can be substituted by asparagine and still retain in vitro polymerase ac...
OBJECTIVES The purpose of this work was to evaluate the feasibility and outcome of elective laparoscopic cholecystectomy as a day-case procedure in a French university hospital. METHODS Since the creation of a surgical day-care centre in 1999, patients without severe chronic disease and anticoagulant therapy were selected for elective laparoscopic cholecystectomy. They were admitted and opera...
This paper presents data from the BIMA interferometer showing spatially resolved absorption spectra of the gravitationally lensed quasar PKS 1830-211. High-resolution (1.2 km s) spectra were taken in two spectral windows centered on the redshifted frequencies of the HCO(2 ← 1) and HCN(2 ← 1) molecular transitions. There is no molecular absorption in the northeast image but the southwest image r...
