Journal ArticleDOI
The use of morphokinetics as a predictor of embryo implantation
TL;DR: A multivariable model is proposed based on the findings to classify embryos according to their probability of implantation and it is proposed that the image acquisition and time-lapse analysis system makes it possible to determine exact timing of embryo cleavages in a clinical setting.
Journal ArticleDOI
Pathways of organic carbon oxidation in three continental margin sediments
Donald E. Canfield,Bo Barker Jørgensen,Henrik Fossing,Ronnie N. Glud,Jens K. Gundersen,Niels B. Ramsing,Bo Thamdrup,Jens Würgler Hansen,Lars Peter Nielsen,Per O. J. Hall +9 more
TL;DR: It is suspected that the importance of O2 respiration in many coastal sediments has been overestimated, whereas metal oxide reduction (both Fe and Mn reduction) has probably been well underestimated.
Journal ArticleDOI
Geographical isolation in hot spring cyanobacteria
TL;DR: A lack of correspondence between biological patterning and the chemical character of springs sampled suggested that the geographical distribution of thermophilic cyanobacteria cannot be explained by the 20 potential niche-determining chemical parameters that were assayed, suggesting geographical isolation must in part be responsible for driving the observed evolutionary divergences.
Journal ArticleDOI
Distribution of sulfate-reducing bacteria in a stratified fjord (Mariager Fjord, Denmark) as evaluated by most-probable-number counts and denaturing gradient gel electrophoresis of PCR-amplified ribosomal DNA fragments.
TL;DR: The sulfate-reducing bacterial populations of a stratified marine water column, Mariager Fjord, Denmark, were investigated by molecular and culture-dependent approaches in parallel and revealed a highly differentiated pattern of rRNA- and rDNA-derived PCR amplificates, probably reflecting active and resting bacterial populations.
Journal ArticleDOI
Concentration and transport of nitrate by the mat-forming sulphur bacterium Thioploca
Henrik Fossing,Victor A. Gallardo,Bo Barker Jørgensen,Markus Hüttel,Lars Peter Nielsen,Heide N. Schulz,Donald E. Canfield,Stefan Forster,Ronnie N. Glud,Jens K. Gundersen,Jan Küver,Niels B. Ramsing,Andreas P Teske,Bo Thamdrup,Osvaldo Ulloa +14 more
TL;DR: In this paper, the authors reported that Thioploca cells are able to concentrate nitrate to up to 500 mM in a liquid vacuole that occupies > 80% of the cell volume.
