DNA Repair Repertoire of the Enigmatic Hydra
Frontiers in Genetics, 2021 Since its discovery by Abraham Trembley in 1744, hydra has been a popular research organism. Features like spectacular regeneration capacity, peculiar tissue dynamics, continuous pattern formation, unique evolutionary position, and an apparent lack of ...

Evolution of hydra, a recently evolved testis-expressed gene with nine alternative first exons in Drosophila melanogaster. [PDF]
PLoS Genetics, 2007 We describe here the Drosophila gene hydra that appears to have originated de novo in the melanogaster subgroup and subsequently evolved in both structure and expression level in Drosophila melanogaster and its sibling species. D.

Overview of Hydra: a concurrent language for synchronous digital circuit design [PDF]
, 2006 Hydra is a computer hardware description language that integrates several kinds of software tool (simulation, netlist generation and timing analysis) within a single circuit specification. The design language is inherently concurrent, and it offers black

Tentacle morphogenesis in hydra [PDF]
, 1990 Stimulation of tentacle-specific cell differentiation by the neuropeptide head activator was investigated in Hydra magnipapillata. Tentacle-specific sensory nerve cells were identified by a monoclonal antibody, NV1.

Logical Methods in Computer Science, 2021 The recursive path ordering is an established and crucial tool in term rewriting to prove termination. We revisit its presentation by means of some simple rules on trees (or corresponding terms) equipped with a 'star' as control symbol, signifying a command to make that tree (or term) smaller in the order being defined.

Transplantation stimulates interstitial cell migration in hydra [PDF]
, 1990 Migration of interstitial cells and nerve cell precursors was analyzed in Hydra magnipapillata and Hydra vulgaris (formerly Hydra attenuata). Axial grafts were made between [3H]thymidine-labeled donor and unlabeled host tissue. Migration of labeled cells

Laboratory test methods to determine the degradation of plastics in marine environmental conditions
Frontiers in Microbiology, 2012 In this technology report, three test methods were developed to characterize the degradation of plastic in marine environment. The aim was to outline a test methodology to measure the physical and biological degradation in different habitats where ...
