  1. 26. Chemical mixtures and interactions with detoxification mechanisms and biomarker responses in fish

    Författare :Johanna Gräns; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fish; AhR; CYP1A; PXR; Chemical mixtures; Chemical interaction; Biomarker;

    Sammanfattning : Several classes of anthropogenic chemicals are present as mixtures in the aquatic environment. However, information of how wildlife species, including fish, are affected by exposures to chemical mixtures is limited. LÄS MER

  2. 27. From Parasitoids to Gall Inducers and Inquilines : Morphological Evolution in Cynipoid Wasps

    Författare :Hege Vårdal; Fredrik Ronquist; Göran Sahlén; Ulf Jondelius; Nunzio Isidoro; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; gall inducer; parasitoid; inquiline; gall induction; morphology; Biologi; Biology; Biologi;

    Sammanfattning : One of the large lineages of parasitic wasps, the Cynipoidea, exhibits three distinctly different life modes. Slightly more than half of the about 3000 species are parasitoids in insect larvae, whereas the remaining species are associated with plants, either as gall inducers or as inquilines (guests feeding on plant tissue in galls).

  3. 28. Equine seminal plasma: its role in protecting stallion spermatozoa during cryopreservation

    Författare :Essraa M Al-Essawe; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : There is considerable variability in the ability of spermatozoa from different stallions to withstand the freezing process. As a result, stallions are usually categorized as good or bad freezers. LÄS MER

  4. 29. Programming Blood Cell Fates. Insights from Direct Lineage Conversion and Development

    Författare :Sandra Capellera Garcia; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic development; Erythropoiesis; Megakaryopoiesis; Direct Lineage Conversion;

    Sammanfattning : Red blood cells (RBC) and platelets constitute the non-immune branch of the hematopoietic system and are responsible for the vital functions of transporting oxygen to the tissues and clotting blood vessel injuries, respectively. These cells are produced during embryonic development and throughout life through a process called hematopoiesis which is tightly regulated by extrinsic and intrinsic factors. LÄS MER

  5. 30. Human intestinal alkaline phosphatase : tissue expression and serum levels

    Författare :Ulla Domar; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Human alkaline phosphatase; intestinal alkaline phosphatase; blood; blood group; lipid; monoclonal antibody; immunohistochemistry; liver; kidney; pancreas; liver disease; inflammatory bowel disease;

    Sammanfattning : Human alkaline phosphatase (ALP) comprises four isozymes, viz liver/bone/ kidney or tissue unspecific (AP), intestinal (LAP), placental (PLAP) and germ cell or PLAP-like alkaline phosphatase, with their main expression in specific tissues as indicated by their names. The isozymes are coded by different genes, but they are closely related, with more than 50% amino acid sequence homologies. LÄS MER
