  1. 1. Teleost retina : a model for study neurogenesis and angiogenesis

    Författare :Satish Srinivas Kitambi; Agneta Mode; Jarema Malicki; Per Kylster; Thomas Burglin; Finn Hallböök; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Teleost models, zebrafish and medaka have become popular models to study various aspects of developmental biology and genetics. The rapid embryonic development, transparent embryos and the availability of many mutants for various developmental and molecular pathways contribute to the usefulness of these models. LÄS MER

  2. 2. Developmental and reproductive regulation of NR5A genes in teleosts

    Författare :Jonas von Hofsten; Per-Erik Olsson; Gregory Kelly; Umeå universitet; []

    Sammanfattning : In mammals sex chromosomes direct and initiate the development of male and female gonads and subsequently secondary sex characteristics. In most vertebrates each individual is pre-destined to either become male or female. LÄS MER

  3. 3. Morphological and Physiological Adaptations in Cichlid Crystalline Lenses

    Författare :Marcus Schartau; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SKF-38393; D1-agonist; optical properties 6-hydroxydopamine; optical measurements; organ culture; dopamine; teleost; lens circulation; Lens; SCH-23390; melatonin; multifocal optical system;

    Sammanfattning : Vertebrate eyes share a common ancestry as well as the basic design with a pupil, a retina and a lens. The lens is essential for perceiving the details in the world around us and ensures that a sharp image of the surroundings is focused onto the photoreceptors in the retina. LÄS MER

  5. 5. On the regulation of Postprandial Gastrointestinal Blood Flow in Teleost Fish

    Författare :Henrik Seth; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Rainbow trout Oncorhynchus mykiss ; Shorthorn sculpin Myoxocephalus scorpius ; Diet composition; Oxygen consumption; Mechanical stimuli; Chemical stimuli;

    Sammanfattning : Henrik Seth (2010) On the Regulation of Postprandial Gastrointestinal Blood Flow in Teleost Fish Department of Zoology/Zoophysiology, University of Gothenburg, Box 463, 405 30 Göteborg. The regulation of the cardiovascular changes, in particular the increase in gastrointestinal blood flow that follows after feeding has received little attention in teleost fish. LÄS MER
