1. 1. Pluripotent Stem Cells of Embryonic Origin : Applications in Developmental Toxicology

   Författare :Måns Jergil; Lennart Dencker; Aldert Piersma; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Embryonic stem cell; Microarray; Toxicogenomics; Valproic acid; Developmental toxicology; Teratogenicity; Neural tube defects; Histone deacetylase inhibitor; In vitro toxicology; Toxicology; Toxikologi; Toxicology; Toxikologi;

   Sammanfattning : General toxicity evaluation and risk assessment for human exposure is essential when developing new pharmaceuticals and chemicals. Developmental toxicology is an important part of this risk assessment which consumes large resources and many laboratory animals. LÄS MER

3. 2. Development of Methods for Assessing Unbound Drug Exposure in the Brain : In vivo, in vitro and in silico

   Författare :Markus Fridén; Margareta Hammarlund-Udenaes; Ulf Bredberg; Yuichi Sugiyama; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; Drug transport; Tissue distribution; Transporters; Pharmacokinetics; Other pharmacy; Övrig farmaci; Biopharmacy; Biofarmaci; Pharmaceutical pharmacology; Farmaceutisk farmakologi; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

   Sammanfattning : The blood-brain barrier is formed by tightly joined capillary cells with transporter proteins and acts as to regulate the brain concentration of nutrients as well as many drugs. When developing central nervous system drugs it is necessary to measure the unbound drug concentration in the brain, i.e. the unbound brain exposure. LÄS MER

4. 3. The Role of Chlamydia pneumoniae-induced Platelet Activation in Cardiovascular Disease : In vitro and In vivo studies

   Författare :Hanna Kälvegren; Torbjörn Bengtsson; Arina Richter; Erik Kihlström; Kenneth Persson; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chlamydia pneumoniae; Platelet; atherosclerosis; Infection; LDL-oxidation; Percutaneous coronary intervention; Cardiovascular disease; Serotonin; Reactive oxygen species production; Pharmacology; Farmakologi;

   Sammanfattning : The common risk factors for atherosclerosis, such as obesity, high cholesterol levels, sedentary lifestyle, diabetes and high alcohol intake, only explain approximately 50% of cardiovascular disease events. It is thereby important to identify new mechanisms that can stimulate the process of atherosclerosis. LÄS MER

5. 4. β-N-methylamino-L-alanine (BMAA)-induced neurotoxicity : Studies in vitro and in vivo

   Författare :Lisa Ersson; Malin Andersson; Eva B Brittebo; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; BMAA; neurotoxin; neurodegeneration; cellular transport; metabolic profiling; protein-association; Farmaceutisk vetenskap; Pharmaceutical Science;

   Sammanfattning : β-N-methylamino-L-alanine (BMAA) is a neurotoxic non-proteinogenic amino acid produced naturally by cyanobacteria, diatoms and dinoflagellates and it has been detected in samples from fresh and marine water from all over the world. It can bioaccumulate in fish and shellfish, and has a potential to biomagnify in a terrestrial food chain. LÄS MER

7. 5. Developmental Neurotoxicity Testing Using In vitro Approaches

   Författare :Helena Högberg; Anna Price; Barbara Cannon; Kevin Crofton; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; Toxikologi; toxikologi; Toxicology;

   Sammanfattning : There is a great concern about children’s health as the developing brain in foetuses and children is much more vulnerable to injury caused by different classes of chemicals than the adult brain. This vulnerability is partly due to the fact that the adult brain is well protected against chemicals by the blood brain barrier (BBB) and children have increased absorption rates and diminished ability to detoxify many exogenous compounds, in comparison to that of adults.
