The intestinal nematode Heligmosomoides bakeri has undergone 2 name changes during the last 4 decades. Originally, the name conferred on the organism in the early 20th century was Nematospiroides dubius, but this was dropped in favour of Heligmosomoides polygyrus, and then more recently H. bakeri, to distinguish it from a closely related parasite commonly found in wood mice in Europe. H. bakeri...

Background We describe a new species in the genus Voria Robineau-Desvoidy, 1830 (Diptera: Tachinidae: Voriini) from Area de Conservación Guanacaste (ACG) in northwestern Costa Rica. It was reared as part of an ongoing inventory of wild-caught caterpillars spanning a variety of moth and butterfly families (Lepidoptera). Our study provides a concise description of the new species using morphology...

(Shaked etal., PLoS ONE 2008). To further investigate this finding, several different approaches have been taken. First, the expression of HDAC-regulated candidate genes responsible for controlling neurogenesis has been examined through quantitative realtime RT-PCR. TSA-based inhibition of HDAC activity resulted in upregulation of Bmp2, Stat1, Stat3, Ngn1 and Ngn2 in neural precursors from both...

Here we report N(2)O emission results for freshwater marshes isolated from human activities at the Sanjiang Experimental Station of Marsh Wetland Ecology in northeastern China. These results are important for us to understand N(2)O emission in natural processes in undisturbed freshwater marsh. Two adjacent plots of Deyeuxia angustifolia freshwater marsh with different water regimes, i.e., seaso...
