  2. 1. Zinc-enriched neurons in the spinal cord, cerebellum and peripheral sympathetic system

    Author : Zhan-You Wang; Göteborgs universitet; []
    Keywords : autometallography; axonal transport; confocal laser scanning microscopy; immuno-electron microscopy; immunofluorescence; inhibitory neurons; sympathetic neurons; synaptic vesicles; zinc ions; zinc transporter;

    Abstract : Zinc ions are abundant in the nervous system and are involved in many biological functions. Most zinc is tightly bound to macromolecules, whereas a small fraction of zinc exists in synaptic vesicles of the zinc-enriched (ZEN) neurons, and can be visualized using various histochemical techniques, including autometallography (AMG).

  4. 2. Immune cells in pregnant uterine mucosa : functional properties, cellular composition and tissue organization

    Author : Lucia Mincheva-Nilsson; Sten Hammarström; Rolf Kiessling; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunologically privileged site; TCR γδ cells; CD56 cells; large granular lymphocytes; immunosuppression; cytokine; interleukin; lymphoid cell cluster; intraepithelial lymphocytes; glandular epithelium; immuno electron microscopy; pregnancy; decidua; lactoferrin; lactoferrin receptor; colostrum;

    Abstract : The pregnant uterus mucosa - decidua - is an "immunologically privileged" site. A semiallogeneic embryo is allowed to survive, develop, and grow while the same tissue implanted outside the uterus will be rejected. The decidua basalis, which participates in the placenta formation, is a tissue rich in lymphoid cells. READ MORE

  5. 3. Salivary gland neoplasms : studies on the cytoskeleton, the secretory apparatus and the nuclear DNA content

    Author : Hans Gustafsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salivary gland neoplasms; intermediate filaments; immuno- histochemistry; ultrastructure; DNA; development; histogenesis; progno¬sis;

    Abstract : The heterogeneity of salivary gland neoplasms have made classification and prognostication of these tumours sometimes difficult, and the in­troduction of techniques, such as enzyme and carbohydrate histochemis­try and electron microscopy have only to a certain extent increased our knowledge in these respects. In the present study immunohistochemical methods have been used to identify intermediate filament proteins (IFP) in normal fetal and adult parotid glands, as well as in salivary neo­plasms.

  6. 4. Cell motility : the organization of the microfilament system in cultured cells with special emphasis on the cortical weave of actin filaments

    Author : Roger Karlsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The microfilament system formed by actin, myosin and associated proteins constitutes the molecular basis for many of the motile phenomena which eukaryotic cells express. The organization of this system varies considerably from cell type to cell type, and is characterized on one hand by strictly ordered, more or less flexible arrangements of actin filaments and on the other by actin present in primarily a nonfilamentous form ready to polymerize in response to certain stimuli.

  7. 5. Chromosome synapsis and recombination in yeast meiosis

    Author : Hasanuzzaman Bhuiyan; Karin Schmekel; Harry Scherthan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; meiosis; recombination; synapsis; yeast; Molecular biology; Molekylärbiologi;

    Abstract : Meiosis is a cell division process that produces haploid gametes from diploid cells. Several important meiotic events take place during prophase of meiosis I, most important being homologous chromosome pairing, meiotic recombination and formation of the synaptonemal complex (SC).
