  1. 41. Exotic Ribosomal Enzymology

    Författare :Josefine Liljeruhm; Anthony C. Forster; Christophe Danelon; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; rRNA modification; Methyltransferase; RlmM; RlmJ; D-amino acid; Unnatural amino acid; Chromoprotein; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : This thesis clarifies intriguing enzymology of the ribosome, the multiRNA/multiprotein complex that catalyzes protein synthesis (translation). The large ribosomal RNAs (23S and 16S rRNAs in E. coli) are post-transcriptionally modified by many specific modification enzymes, yet the functions of the modifications remain enigmatic. LÄS MER

  3. 42. 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

    Författare :Charles Kennergren; Göteborgs universitet; []
    Nyckelord :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;

    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

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

    Författare :Sebastian Hirner; Peter Somfai; Varinder Aggarwal; KTH; []
    Nyckelord :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;

    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

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

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

    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

  7. 45. Immunocytochemical studies of excitatory amino acid neurotransmitters and transporters in the spinal cord and nucleus submedius

    Författare :Stefan Persson; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurophysiology; neuropsychology; Neurology; VGLUT2; VGLUT1; pain; somatosensory; thalamus; immunogold; glutamate; aspartate; dorsal horn; excitatory amino acids; spinal cord; neurofysiologi; Neurologi;

    Sammanfattning : The amino acid glutamate is today regarded as the main fast excitatory neurotransmitter in the central nervous system and a large body of evidence support that glutamate serves as a neurotransmitter in primary afferent terminals in the spinal cord. Previous evidence also suggests that the closely related amino acid aspartate may serve a similar role in some primary afferent terminals. LÄS MER
