Caenorhabditis elegans is currently introduced as a new, facile, and cheap model organism to study the pathogenesis of gram-negative bacteria such as Pseudomonas aeruginosa and Salmonella enterica serovar Typhimurium. The mechanisms of killing involve either diffusible exotoxins or infection-like processes. Recently, it was shown that also some gram-positive bacteria kill C. elegans, although t...
BACKGROUND The simple and well-described structure of the C. elegans nervous system offers an unprecedented opportunity to identify the genetic programs that define the connectivity and function of individual neurons and their circuits. A correspondingly precise gene expression map of C. elegans neurons would facilitate the application of genetic methods toward this goal. Here we describe a pow...
the date palm fruit stalk borer is one of the most important pests of date palm in the world. biochemical properties of digestive proteases in oryctes elegans prell larvae were investigated in this research and optimal total proteolytic and trypsin activities were obtained at ph 9.0 and 11.0, respectively. activity staining of protease on sds-page showed one isoform. also, zymogram pattern of t...
the discovery of rna interference (rnai) in recent years has revolutionized biological and medical research. rnai is the sequence-specific gene silencing triggered by double-stranded rna (dsrna). until a couple of years ago only biologists working with caenorhabditis elegans and plants could use rnai technology to gain insight into gene function……
گیاه sameraria stenophylla به عنوان گونه جدیدی از شرق ایران گزارش می شود. این گونه به سادگی با داشتن گلبرگ های بلند و سرنیزه ای بودن قاعده برگ های ساقه ای از گونه مجاور خود یعنی sameraria elegans قابل تفکیک است. نقشه پراکنش این گونه و نزدیکترین خویشاوند آن به همراه تصویری از این گونه ارائه می شود.
The Caenorhabditis elegans oocyte is a highly amenable system for forward and reverse genetic analysis of receptor-mediated endocytosis. We describe the use of transgenic strains expressing a vitellogenin::green fluorescent protein (YP170::GFP) fusion to monitor yolk endocytosis by the C. elegans oocyte in vivo. This YP170::GFP reporter was used to assay the functions of C. elegans predicted pr...
WormBase (www.wormbase.org) is the major publicly available database of information about Caenorhabditis elegans, an important system for basic biological and biomedical research. Derived from the initial ACeDB database of C. elegans genetic and sequence information, WormBase now includes the genomic, anatomical and functional information about C. elegans, other Caenorhabditis species and other...
Ecdysteroids (insect molting hormones) from Caenorhabditis elegans were chromatographically purified and quantified by radioimmunoassay. Nematodes from semidefined medium contained the immunoreactive equivalent of 460 pg ecdysone per gram dry weight. Culture medium, however, contained the immunoreactive equivalent of 68 times the quantity within the nematodes. In a defined medium lacking immuno...
As an effective soil amendment, biochars require a comprehensive ecological evaluation before they can be widely used in agriculture because endogenous contaminants, such as environmentally persistent free radicals (EPFRs), certainly pose risk to invertebrates. In this study, Caenorhabditis elegans (C. elegans) was model organism investigate the neurotoxicity of two rice straw pyrolyzed at 500 ...
The Caenorhabditis elegans (C. elegans) is an ideal model organism for studying human diseases and genetics due to its transparency suitability optical imaging. However, manually sorting a large population of C. experiments tedious inefficient. microfluidic-assisted chip considered promising platform address this issue automation ease operation. Nevertheless, automated with multiple parameters ...
