  2. 21. Mass Spectrometry of Non-protein Amino Acids : BMAA and Neurodegenerative Diseases

    Author : Liying Jiang; Leopold Ilag; Jonas Bergquist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neurodegenerative diseases; BMAA; Isomers; LC-MS MS; Cyanobacteria; Diatoms; Seafood contamination; Analytical Chemistry; analytisk kemi;

    Abstract : 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. READ MORE

  4. 22. Cytokines and lipids in pregnancy – effects on developmental programming and placental nutrient transfer

    Author : Susanne Lager; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adipose tissue; amino acids; cytokines; developmental programming; free fatty acids; insulin resistance; interleukin-6; lipoprotein lipase; nutrient transport; placenta; toll-like receptor 4;

    Abstract : 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. READ MORE

  5. 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

    Author : Charles Kennergren; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac surgery; myocardial ischemia; microdialysis; interstitial markers; ASAT; troponin-T; amino acids; glucose; lactate;

    Abstract : 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. READ MORE

  6. 24. New Methodologies in Organic Chemistry: Applications to the Synthesis of α-Amino Acids and Natural Products

    Author : Sebastian Hirner; Peter Somfai; Varinder Aggarwal; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic synthesis; 2-Vinylaziridines; 3-Pyrrolines; Ringexpansion; Rearrangement; Anisomycin; Total synthesis; α-Amino acids; Arylglycines; Weinreb amides; α-Arylation; Grignard reagents; Umpolung; Organic chemistry; Organisk kemi;

    Abstract : 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. READ MORE

  7. 25. Molecular mechanisms and biological consequences of the production of non-canonical D-amino acids in bacteria

    Author : Alena Aliashkevich; Felipe Cava; Fredrik Almqvist; Andrew J Roe; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bacteria; cell wall; peptidoglycan; D-amino acids; LD-transpeptidase;

    Abstract : 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. READ MORE
