Conditioning planaria : device design based on an autonomous, large-scale parallel approach
Current behavioral research is conducted on planaria that have been conditioned manually, one at a time by a person. In an attempt to instrument at an organism level, a design for an environment that automatically conditions multiple planaria in parallel was produced. This design consisted of a …

Schmidtea mediterranea planaris as a novel animal model for investigating the dynamics of nervous system development in fetal alcohol spectrum disorder
… thesis, we propose that the freshwater flatworm planarian species, Schmidtea mediterranea, has the capability to fulfill this need. Planaria have the ability to completely regenerate fragments into intact, functional animals, and in these studies, we exploited this property to characterize …

Control Method for Invasive Aquatic Species introduced via Ballast Water: Effects of Carbon Dioxide Supersaturation on Survivorship of Digesia tigrina (Planaria: Maculata) and Lirceus brachyurus (Isopoda: Crustacea) and Effect of High Hydrostatic Pressure Processing on Freely Suspended and Shellfish Associated T7 Bacteriophage
… on Survivorship of Digesia tigrina (Planaria: Maculata) and Lirceus brachyurus (Isopoda: Crustacea) Survivorship of an aquatic species of planaria (Digesia tigrina) and isopods (Lirceus barchyurus) to elevated levels of carbon dioxide (CO₂) was determined. Both planaria and isopods …

An investigation into the antineoplastic properties of Schinziophyton Rautanenii and Colophospermum mopane
… Extracts were also assayed in vivo in Planaria, for toxicity. Alkaloids, coumarins, flavonoids and triterpenes were found in all plant extracts, except anthraquinones which were only found in the root extract of S. rautanenii. Antioxidant activity shown by plant extracts was in …

Light Enhanced Toxic/tumorigenic Potential of Trinitrotoluene (Tnt) and Analogs
… magna (daphnia), and Dugesia dorotocephala (planaria) was enhanced by near-ultraviolet light (nUV) coexposure. The light enhanced toxicity of TNT, 2A and 4A must be considered to fully evaluate the environmental hazards of these compounds. The 2A and 4A metabolites of TNT were toxic at …

Modelling and managing the effects of trout farms on Cape rivers
… with Naididae, Lumbriculidae, Chironomidae and Planaria. Once-off chemical samples were also collected at each site and, acknowledging the limitations of the sampling strategy, results showed that the particulate fraction of the effluent was probably responsible for the recorded reaction of the …

Barcoding tools to track development and function of stem cell constructs for biomedicine
… studied the remarkable regeneration potential of Planaria. Yet increasing work suggests processes including complex cellular growth dynamics, patterns of gene expression and clonal expansion of cells drives regeneration and analogously, biological tissue development. Improved understanding of …

Functional genomic studies of regeneration in the planarian Schmidtea mediterranea
Regenerative capabilities are seen in varying degrees throughout the phylogenetic tree. Are the genes and signaling pathways employed by regeneration found in all metazoans and recruited by mechanisms conserved in regenerative organisms, or have organisms developed ways to recruit them de novo? We …

Characterizing neural tissues with mass spectrometry imaging via enhanced computational approaches
… the timecourse of nervous system regeneration in planarian flatworms resulting in the discovery of two novel neuropeptides that may be involved in planarian regeneration. In addition, several bioinformatic tools are developed to predict final neuropeptide structures and associated masses that can …
