1. Studies of nucleotide receptors-induced calcium response in glomerular mesangial cells and afferent arterioles
Sammanfattning : It is known that intracellular calcium concentration ([Ca2+]i) changes in rat glomerular mesangial cells (GMC) and rabbit afferent arterioles (AA) in response to extracellular nucleotides. We studied the nucleotide-induced calcium response in cultured GMC and AA. LÄS MER
Sammanfattning : This thesis describes the studies of the GABAA receptor, a ligand-gated ion channel, and the ligand- and temperature-gated ion channel TRPV1. The desensitization behavior of both of these proteins has been studied for different conditions, using a microfluidic device for superfusion. LÄS MER
3. Psycho-physiological reactions to violent video gaming : Experimental studies of heart rate variability, cortisol, sleep and emotional reactions in teenage boys
Sammanfattning : Playing violent video games may provoke aggression. Psycho-physiological methods may provide knowledge about the underlying psychological processes. Most previous studies have been performed in laboratory settings at daytime with adults. LÄS MER
Sammanfattning : Movements of a receptor in the plasma membrane and within the cell influence receptor function and physiology. I have investigated the role of such movements, generally known as membrane trafficking, in G protein-coupled receptor regulation. LÄS MER
Sammanfattning : The tubuloglomerular feedback mechanism is an important regulator in the juxtaglomerular apparatus and it detects flow dependent alterations in luminal NaCl concentration ([NaCl]) at the macula densa (MD) cell site via a Na+-K+-2Cl cotransporter. Signals are sent by the MD to adjust the afferent arteriole tone and altering release of renin. LÄS MER
