21. Mass Spectrometry of Non-protein Amino Acids : BMAA and Neurodegenerative Diseases
Sammanfattning : Neurodegenerative diseases have been shown to correlate positively with an ageing population. The most common neurodegenerative diseases are amyotrophic lateral sclerosis (ALS), Parkinson’s disease and Alzheimer’s disease. LÄS MER
22. Cytokines and lipids in pregnancy – effects on developmental programming and placental nutrient transfer
Sammanfattning : Metabolic disturbances, in particular those associated with nutritional challenges, that take place during development, both in utero and early postnatal life, have long-lasting health consequences on an individual. The most pronounced evidence of these challenges is a deviation in birth weight. LÄS MER
23. Cellular monitoring in open heart surgery. Monitoring of markers for ischemia, free amino acids, glucose and lactate in the myocardial interstitial fluid before, during and after cardiac surgery using microdialysis technique
Sammanfattning : Protection of the myocardium during open-heart surgery is a field of intense development. Numerous protocols have been proposed to minimize ischemia, since the beginning of open-heart surgery more than 40 years ago. LÄS MER
24. New Methodologies in Organic Chemistry: Applications to the Synthesis of α-Amino Acids and Natural Products
Sammanfattning : This thesis deals with the development and application of new synthetic methodology in organic chemistry. The first part describes the development of a new protocol for the synthesis of 3-pyrrolines by means of a microwave-assisted ring-expansion reaction of 2-vinylaziridines. LÄS MER
25. Molecular mechanisms and biological consequences of the production of non-canonical D-amino acids in bacteria
Sammanfattning : Most bacteria possess a vital net-like macromolecule – peptidoglycan (PG). PG encases bacteria around the cytoplasmic membrane to withstand the high internal turgor pressure and thereby protect the cell from bursting. In addition, PG is a major morphological determinant of bacteria being both required and sufficient to maintain cell shape. LÄS MER
