Hydra A: a New Picture
We present new, low-frequency images of the powerful FRI radio galaxy Hydra A (3C218), which lies at the center of the poor Abell cluster A780. Images were made with the Very Large Array at frequencies of 1415, 330, and 74 MHz, with resolutions on the order of 20 . The morphology of the source is seen to be more complex and larger than previously known, and extends nearly 8 (530 kpc) in a North...
متن کاملEpithelial interactions in Hydra: apoptosis in interspecies grafts is induced by detachment from the extracellular matrix.
Apoptosis plays an important role in immunity and is widely used to eliminate foreign or infected cells. Cnidaria are the most basal eumetazoans and have no specialised immune cells, but some colonial cnidarians possess a genetic system to discriminate between self and non-self. By grafting epithelia of different species we have previously shown that the freshwater polyp Hydra eliminates non-se...
متن کاملDevelopment and population growth of Hydra viridissima Pallas, 1766 (Cnidaria, Hydrozoa) in the laboratory.
Hydras, the most representative freshwater Cnidaria, are of common occurrence in bodies of water in every continent except Antarctica. This study was planned with the aim of maintaining a population of Hydra viridissima in laboratory culture to enable the determination of the individual and population growth-rates of this species, as well as its population doubling time and generation time, wit...
متن کاملEffects of norflurazon on green and brown hydra.
For the first time effects of norflurazon on green (Hydra viridissima Pallas, 1766) and brown hydra (Hydra oligactis Pallas, 1766) in high- and low-light conditions were investigated in order to establish the extent of damage that this substance inflicts, with special emphasis on the "bleaching effect" and the effect on hydra-algae symbiosis. Green hydra is a typical example of an endosymbiotic...
متن کاملThrombospondin Type-1 Repeat Domain-Containing Proteins Are Strongly Expressed in the Head Region of Hydra
The head region of Hydra, the hypostome, is a key body part for developmental control and the nervous system. We herein examined genes specifically expressed in the head region of Hydra oligactis using suppression subtractive hybridization (SSH) cloning. A total of 1414 subtracted clones were sequenced and found to be derived from at least 540 different genes by BLASTN analyses. Approximately 2...
