31. Neuromodulation within a spinal locomotor network : role of metabotropic glutamate receptor subtypes
Sammanfattning : The metabotropic glutamate receptors, mGluRs, are G-protein coupled receptors. They consist of eight cloned subtypes, which are divided into three groups depending on the amino acid sequence similarity, pharmacology and their signal pathways. LÄS MER
32. Experimental studies of N-methyl-D-aspartate receptor NR3 subunits
Sammanfattning : This thesis focuses on the NR3A and NR3B subunits of the excitatory glutamate receptor N-methyl-D-aspartate (NMDA). Functional NMDA receptors are believed to be tetrameric complexes with combinations of NR1 and NR2 subunits, and possible addition of NR3 subunits. LÄS MER
33. Development of in vitro and ex vivo positron-emitting tracer techniques and their application to neurotrauma
Sammanfattning : The use of positron-emitting tracers has been extended beyond tomographic facilities in the last few years, giving rise to a general positron-emitting tracing technique. The methodological part of the present thesis involved the evaluation of the performance of storage phosphor (SP) plates, with tracers labeled with high-energy, short-lived, positron-emitting radionuclides, using homogenized tissue specimens and autoradiography with frozen brain sections.

34. Physiopathological aspects of NMDA transmission in the basal ganglia : in vitro and in vivo release studies
Sammanfattning : N-methyl-D-aspartic acid (NMDA) is an excitatory amino acid selectively acting on a subclass of glutamate receptors (the NMDA ionotropic receptor) which has been involved in many of the physiological and pathological effects of glutamate in the CNS. The basal ganglia are particularly enriched in NMDA receptors and NMDA receptor activation in the basal ganglia has been involved in the expression of motor behaviour. LÄS MER
35. Synthesis and structure activity relationships of competitive NMDA antagonists with analgesic activity
Sammanfattning : The compounds cis-3-(1-oxo-2-phosphonoethyl)-2-piperidinecarboxylic acid 1 and cis-3-(1-hydroxy-2-phosphonoethyl)-2-piperidinecarboxylic acid 2 were synthesized and found to be potent N-methyl-D-aspartate (NMDA) antagonists. NMR analysis showed that 1 prefers a 2eq,3ax chair conformation probably due to a conformer-stabilizing internal hydrogen bond. LÄS MER
