1. 1. Amyloid-β Protofibril Formation and Neurotoxicity : Implications for Alzheimer’s Disease

   Författare :Ann-Sofi Johansson; Lars Lannfelt; Frida Ekholm Pettersson; Pär Gellerfors; Tobias Hartmann; Uppsala universitet; []
   Nyckelord :Neurosciences; Amyloid-β; Neurotoxicity; Aggregation; Protofibrils; Alzheimer s disease; Neurovetenskap;

   Sammanfattning : Alzheimer’s disease (AD) is the most common cause of dementia. A characteristic feature of AD is the presence of amyloid plaques in the cortex and hippocampus of the brain. The principal component of these plaques is the amyloid-β (Aβ) peptide, a cleavage product from proteolytic processing of amyloid precursor protein (APP). LÄS MER

3. 2. In vitro cellular models for neurotoxicity studies : neurons derived from P19 cells

   Sammanfattning : Humans are exposed to a variety of chemicals including environmental pollutants, cosmetics, food preservatives and drugs. Some of these substances might be harmful to the human body. LÄS MER

4. 3. Proteomic Characterization of Induced Developmental Neurotoxicity

   Sammanfattning : The developing brain goes through a number of developmental periods during which it displays an increased sensitivity to exogenous disturbances. On such period is the so called “Brain growth spurt” (BGS) which in humans takes place starting from the third trimester of pregnancy and throughout the first few years of life. LÄS MER

5. 4. Low-Dose Ionizing Radiation Induces Neurotoxicity in the Neonate : Acute or fractionated doses and interaction with xenobiotics in mice

   Författare :Sonja Buratovic; Per Eriksson; Henrik Viberg; Bo Stenerlöw; Anders Fredriksson; Jean-René Jourdain; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ionizing radiation; Neonatal; Neurotoxicity; Behaviour; Nicotine; Ketamine; Mouse; Cognition; Acute irradiation; Fractionated irradiation;

   Sammanfattning : This thesis examines the developmental neurotoxic effects of exposure to low-dose ionizing radiation (IR), alone or together with xenobiotics, during a critical period of neonatal brain development in mice.During mammalian brain development there is a period called the brain growth spurt (BGS), which involves extensive growth and maturation of the brain.

7. 5. Neurotoxicity of β-lactam antibiotics : experimental kinetic and neurophysiological studies

   Författare :Silvia E. Schliamser; Ragnar Norrby; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; benzylpenicillin; blood-brain barrier; ß-lactam antibiotics; CSF; CNS; EEG; imipenem cilastatin; FCE 22101; meningitis; neurotoxicity of; silent-second; thiopental; transport system; uraemia;

   Sammanfattning : The neurotoxic potential of intravenous administered benzylpenicillin (BPC) was studied in rabbits with intact blood-CNS barriers and rabbits with experimental E. coli meningitis. At onset of epileptogenic EEG activity or seizures, serum, CSF and brain tissue were collected for assay of BPC. LÄS MER
