3. 2. Experimental Studies of Endocrine Disrupting Compounds in Vascular Cells and Tissues

   Författare :Helén Andersson; Eva Brittebo; Malin Celander; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrine disrupting compounds; endothelium; vascular toxicity; Toxicology; Toxikologi;

   Sammanfattning : Epidemiological evidence suggest that exposure to endocrine disrupting compounds (EDCs) is a risk factor for diseases that involves the cardiovascular system but we know little about the mechanisms whereby these compounds can cause injury in the vasculature. The aim of this thesis was to characterize the effects and mechanisms of some EDCs in vascular cells and highly vascularized tissues. LÄS MER

4. 3. 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

5. 4. Olfactory Transfer of Analgesic Drugs After Nasal Administration

   Författare :Ulrika Espefält Westin; Erik Björk; Eva Brittebo; Margareta Hammarlund-Udenaes; Paolo Colombo; Uppsala universitet; []
   Nyckelord :Pharmaceutics; Nasal administration; Olfactory transfer; Olfactory pathways; Central nervous system; Blood-brain barrier; Nasal respiratory mucosa; Olfactory mucosa; Olfactory bulb; Horizontal Ussing chamber; Morphine; Dihydroergotamine; Rat; Mouse; Swine; Autoradiography; Viability; Powder formulations; Galenisk farmaci;

   Sammanfattning : Nasal administration of analgesics for achieving rapid pain relief is currently a topic of great interest. The blood-brain barrier (BBB) restricts access to the central nervous system (CNS) for several central-acting drugs, such as morphine and dihydroergotamine, which results in a substantial effect delay.

7. 5. Tissue-Selective Activation and Toxicity of Substituted Dichlorobenzenes : Studies on the Mechanism of Cell Death in the Olfactory Mucosa

   Författare :Anna Franzén; Eva Brittebo; Ingvar Brandt; Olavi Pelkonen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; tissue-selective toxicity; bioactivation; olfactory mucosa; substituted dichlorobenzenes; Bowman s glands; sustentacular cells; ER stress; Grp78; caspase-12; caspase-3; CYP2A5; protein adduction; nasal toxicity; Toxikologi; Toxicology; Toxikologi;

   Sammanfattning : The nasal passages are constantly exposed to both air- and bloodborne foreign compounds. In particular, the olfactory mucosa is demonstrated to be susceptible to a variety of drugs and chemicals. LÄS MER
