| demographic fitness of belminus ferroae (hemiptera: triatominae) on three different hosts under laboratory conditions. | triatominae are widely recognised for their role as vectors of trypanosoma cruzi. one of the main biological characteristics of this subfamily is their obligate haematophagous condition. however, previous studies on belminus herreri and belminus ferroae suggested that cockroaches are their principal hosts in domiciles. due to this peculiar behaviour, the aim of this study was to analyse several demographic and reproductive parameters of b. ferroae fed on three different hosts (mice, cockroaches ... | 0 | 24141961 |
| the global invertebrate genomics alliance (giga): developing community resources to study diverse invertebrate genomes. | over 95% of all metazoan (animal) species comprise the "invertebrates," but very few genomes from these organisms have been sequenced. we have, therefore, formed a "global invertebrate genomics alliance" (giga). our intent is to build a collaborative network of diverse scientists to tackle major challenges (e.g., species selection, sample collection and storage, sequence assembly, annotation, analytical tools) associated with genome/transcriptome sequencing across a large taxonomic spectrum. we ... | 0 | 24336862 |
| purification and studies on characteristics of cholinesterases from daphnia magna. | due to their significant value in both economy and ecology, daphnia had long been employed to investigate in vivo response of cholinesterase (che) in anticholinesterase exposures, whereas the type constitution and property of the enzyme remained unclear. a type of che was purified from daphnia magna using a three-step procedure, i.e., triton x-100 extraction, ammonium sulfate precipitation, and diethylaminoethyl (deae)-sepharose™-fast-flow chromatography. according to sodium dodecyl sulfate poly ... | 0 | 23549850 |
