Worms in Space: Epigenetic Response of C. Elegans in Simulated Microgravity

Sticky worms: adhesion complexes in C. elegans.

Caenorhabditis elegans is a powerful model system for investigating the establishment, regulation and function of adhesive structures in vivo. C. elegans has several adhesion complexes related to those in vertebrates. These include: (1) epithelial apical junctions, which have features of both adherens and tight junctions; (2) dense bodies, which are muscle-attachment structures similar to focal...

Silymarin and Related Favonoids Counteract Stress of Simulated Microgravity in the Nematode Caenorhabditis elegans

Speech signal de-noising plays an important role in numerous applications, including speech synthesis, recognition and also a necessary step for speech feature extraction, e.g., pitch track estimation. To acquire an accurate pitch track, the speech signal should have minimum noise interruption. Noise is usually generated by environments or electronic equipments during the recording of the speec...

Epigenetic Regulation of the X Chromosomes in C. elegans

The Effect of Erythropoietin on Rat’s Red Blood Cell Indices in Simulated Microgravity (Experimental Study)

Purpose: Microgravity causes major changes in various systems of the body in space, such as shift in cerebrospinal fluid, decreased red blood cells count, and electrolyte loss. These complications are very important in space and we should find new approaches to prevent the side effects of microgravity in astronauts. Materials and Methods: This experimental study was conducted on 21 adult ma...

Running Worms: C. elegans Self-Sorting by Electrotaxis

The nematode C. elegans displays complex dynamical behaviors that are commonly used to identify relevant phenotypes. Although its maintenance is straightforward, sorting large populations of worms when looking for a behavioral phenotype is difficult, time consuming and hardly quantitative when done manually. Interestingly, when submitted to a moderate electric field, worms move steadily along s...
