    Abstract : The neuropeptide Y (NPY) system consists of 3-4 peptides and 4-7 receptors in vertebrates. It has powerful effects on appetite regulation and is involved in many other biological processes including blood pressure regulation, bone formation and anxiety. READ MORE

  2. 2. Sperm Membrane Channels, Receptors and Kinematics Using boar spermatozoa for drug toxicity screening

    University dissertation from Linköping : Linköping University Electronic Press

    Abstract : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. READ MORE

  3. 3. The influence of lysozyme and oligothiophenes on amyloid-β toxicity in models of Alzheimer’s disease

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Linnea Sandin; Linköpings universitet.; Linköpings universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Alzheimer’s disease (AD) is a neurodegenerative disease and the most common cause of dementia worldwide. Apart from dominantly inherited mutations, age is the major risk factor and as life expectancy increases the prevalence for AD escalates dramatically. READ MORE

  4. 4. Transcriptional profiling of human embryonic stem cells and their functional derivatives

    University dissertation from Göteborg : University of Gothenburg

    Author : Jane Synnergren; Högskolan i Skövde.; Högskolan i Skövde.; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Naturvetenskap; Natural sciences; transcription; differentiation; human embryonic stem cells; gene expression;

    Abstract : Human    embryonic    stem    cells    (hESCs)    represent    populations    of    pluripotent, undifferentiated  cells  with  unlimited  replication  capacity,  and  with  the  ability  to differentiate into any functional cell type in the human body. Based on these properties, hESCs  and  their  derivatives  provide  unique  model  systems  for  basic  research  on embryonic development. READ MORE

  5. 5. Investigating Amyloid β toxicity in Drosophila melanogaster

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Maria Jonson; Linköpings universitet.; Linköpings universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : In this thesis Drosophila melanogaster (the fruit fly) has been used as a model organism to study the aggregation and toxic properties of the human amyloid β (Aβ) peptide involved in the onset of Alzheimer's disease (AD). AD is one of many misfolding diseases where the important event of a protein to adopt its’ specific three-dimensional structure has failed, leading to aggregation and formation of characteristic amyloid fibrils.
