  2. 1. Molecular aspects on voltage-sensor movement

    Author : Amir Broomand; Fredrik Elinder; Guiscard Seebohm; Linköpings universitet; []
    Keywords : Potassium channels; voltage-gated; chemistry; metabolism; physiology; patch-clamp techniques; oocytes; MEDICINE; MEDICIN;

    Abstract : Voltage-gated ion channels are fundamental for electrical signaling in living cells. They are composed of four subunits, each holding six transmembrane helices, S1-S6. Each subunit contains a voltage-sensor domain, S1-S4, and a pore domain, S5-S6. READ MORE

  4. 2. The Complex Genetics of Mouse Reproduction and Arhritis

    Author : Maria Liljander; Immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; morula; B10.Q mice; genetics.; Pregnancy; CIA; reproduction; QTL; superovulation; blastocysts; oocytes; litter size; RA; NFR N mice; MHC;

    Abstract : ABSTRACT Optimal breeding of mice is very important in biomedical science today. The understanding why some strains breed better and some worse enable scientists to create better in vivo models for human diseases. READ MORE

  5. 3. Zinc Oxide Nanostructure Based Electrochemical Sensors and Drug Delivery to Intracellular Environments

    Author : Muhammad Asif; Magnus Willander; Omer Nour; Sunil Bhand; Linköpings universitet; []
    Keywords : ZnO nanorods; Intracellular electrochemical sensor; Functionalization; Metal ions; Glucose; Human Adipocytes; Frog Oocytes; Airway surface liquid; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The nanoscale science and nanostructure engineering have well established in the fabrication of novel electrochemical biosensors with faster response and higher sensitivity than of planar sensor configurations. Moreover nanostructures are suggested and used as efficient carrier of photosensitizers for cancerous cell treatment. READ MORE

  6. 4. Human ovarian follicles and oocytes : collection, cryopreservation, culture and gene expression

    Author : Pu Zhang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Ovarian follicle; oocyte; follicular aspirate; organ culture; cAMP; cGMP; cryopreservation; microarray; human gene expression; embryonic stem cell; preimplantation;

    Abstract : Infertility affects approximately 15% of couples globally. The most effective treatment today is in vitro fertilization. However, not all couples can be helped with the current techniques. To achieve better success, techniques of storage and in vitro maturation of ovarian follicles have to be improved. READ MORE

  7. 5. The role of ion channels and intracellular metal ions in apoptosis of Xenopus oocytes

    Author : Ulrika Englund; Fredrik Elinder; Johan Brask; Katarina Kågedal; Dan Klaerke; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Apoptosis is one type of programmed cell death, important during tissue development and to maintain the tissue homeostasis. Apoptosis comprises a complex network of internal signaling pathways, and an important part of this signaling network is the action of voltage‐gated ion channels. READ MORE
