    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Invertebrates; Immune system; Haemocytes; Manganese Mn ; Immunotoxicology; Crustacea; Mollusca; Echinodermata;

    Abstract : Manganese, Mn, is an abundant element in nature, particularly in soft bottom sediments of the oceans and in bedrock. The metal is predominantly bound to the sediment in the colloid state, MnO2. READ MORE

  4. 2. Gene expression and regeneration in ophiuroids: A study of transcriptional activity and regeneration in the temperate Amphiura filiformis and Antarctic Ophionotus victoriae

    Author : Gavin Burns; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; echinoderm; regeneration; ophiuroid; gene expression; antarctica;

    Abstract : Regeneration, in which lost or damaged tissues are re-grown, is a common phenomenon amongst animals and especially so within the ophiuroids (brittle stars) of the phylum echinodermata. The process of regeneration begins with the injury event followed by a period of cell and tissue reorganization which results in wound healing and tissue re-growth. READ MORE

    Abstract : In all living organisms, biological activities such as proper functioning and co-ordination of different organs will depend on different cells and molecular interactions. In some organisms the loss of functional organs or damage of organs can be lethal, whereas in others a special process called regeneration can retrieve lost organs. READ MORE
