Uptake without inactivation of human adenovirus type 2 by Tetrahymena pyriformis ciliates

Tamar Kohn, Margot Ninon Lauren Olive

Human adenoviruses are ubiquitous contaminants of surface water. Indigenous protists may interact with adenoviruses and contribute to their removal from the water column, though the associated kinetics and mechanisms differ between protist species. In this ...

The first observation that PBBTPD, a low bandgap, ambipolar conjugated donor-acceptor (DA) polymer based on benzobisthiadiazole (BBT), possesses an open-shell singlet ground state as well as a thermally accessible triplet state is described. Similarly, int ...

Wiley-Blackwell2015

Mycobacterium tuberculosis, the causative agent of tuberculosis, possesses a class Ib ribonucleotide reductase (RNR), encoded by the nrdE and nrdF2 genes, in addition to a putative class II RNR, encoded by nrdZ. In this study we probed the relative contrib ...

Dissection of cell division processes in the one cell stage Caenorhabditis elegans embryo by mutational analysis

Pierre Gönczy

To identify novel components required for cell division processes in complex eukaryotes, we have undertaken an extensive mutational analysis in the one cell stage Caenorhabditis elegans embryo. The large size and optical properties of this cell permit obse ...

Telomerase and the chromosome end replication problem

Joachim Lingner

Telomerase, the enzyme that extends chromosomal DNA ends in most eukaryotes, contains essential RNA and protein subunits. We have been studying telomere replication in hypotrichous ciliates such as Euplotes aediculatus, which have numerous short macronucle ...

Regulation of metallothionein gene expression in Cd- or Zn-adapted RK-13 cells

Freddy Radtke

We explored the molecular genetics underlying the massive induction of isoMTs by Zn2+ or Cd2+ in metal tolerant rabbit kidney (RK-13) sub-line cells, using band shift assays and Southern blotting analysis. In sub-line cells accommodated to intermediate met ...
