At present, more and people are suffering from various diseases it is particularly important to find a suitable biological model evaluate the prevention treatment effects of drugs active ingredients on diseases. In all models, Caenorhabditis elegans kind organism that easy observe cultivate, has clear genetic background high degree signal pathway conservation with humans. A variety such as poly...

We have synthesized Eu-doped NaBi(MoO 4 ) 2 nanoparticles functionalized with PAA whose properties make them excellent multimodal contrast agents for X-ray computed tomography and luminescent bioimaging, as illustrated using a C. Elegans animal model.

We exploit the reduced space of C. elegans postures to develop a novel tracking algorithm which captures both simple shapes and also self-occluding coils, an important, yet unexplored, component of 2D worm behavior. We apply our algorithm to show that visually complex, coiled sequences are a superposition of two simpler patterns: the body wave dynamics and a head-curvature pulse. We demonstrate...

To determine whether a C. elegans bioassay could predict mammalian developmental activity, we selected diverse compounds known and known not to elicit such activity and measured their effect on C. elegans egg viability. 89% of compounds that reduced C. elegans egg viability also had mammalian developmental activity. Conversely only 25% of compounds found not to reduce egg viability in C. elegan...

Only two species of Didelphidae are currently recognized in Chile, the sister species Thylamys elegans, endemic of Mediterranean ecorregion and Thylamys pallidior, the inhabitant of the Puna and desert canyons. Three subspecies have been described for T. elegans: T. e. elegans, T. e. coquimbensis and T. e. soricinus. However, a recent study based on morphological analyses, synonymized T. elegan...

Context Understanding the effects that learned responses to being captured have on subsequent recapture rates and associated abundance estimates is important for developing accurate descriptions of populations communities. Although variation in willingness individual turtles be trapped commonly mentioned literature, few studies experimentally tested trap avoidance (or fondness) turtles. Aims To...

Compared to mammals, insects, and plants, relatively little is known about innate immune responses in the nematode Caenorhabditis elegans. Previous work showed that Salmonella enterica serovars cause a persistent infection in the C. elegans intestine that triggers gonadal programmed cell death (PCD) and that C. elegans cell death (ced) mutants are more susceptible to Salmonella-mediated killing...
