The abundance and species composition of ciliates were analyzed in the Bukan Dam Reservoir (West Azerbaijan, Iran) from January to December 2008. Surface water samples were collected at monthly intervals from the middle (Stations 1 and 3) and shallow (Stations 2 and 4) areas of the lake. Three samples were taken in the water column using a 5-litre sampler. Totally 30 liters water was collected...

The accuracy of ribosomal translation is achieved by an initial selection and a proofreading step, mediated by EF-Tu, which forms a ternary complex with aminoacyl(aa)-tRNA. To study the binding modes of different aa-tRNAs, we compared cryo-EM maps of the kirromycin-stalled ribosome bound with ternary complexes containing Phe-tRNA(Phe), Trp-tRNA(Trp), or Leu-tRNA(LeuI). The three maps suggest a ...

an international conference took place in the Lederle Graduate Research Tower of the University of Massachusetts at Amherst, with funding provided by the Richard Lounsbery Foundation, New York City. Its title marked the centennial of centriolekinetosome research and commemorated the two founders of the field: Mihaly Lenhossek (1863–1937), the Hungarian neurobiologist and relative of conference ...
