  2. 1. 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. 2. β-N-methylamino-L-alanine (BMAA)-induced neurotoxicity : Studies in vitro and in vivo

    Author : Lisa Ersson; Malin Andersson; Eva B Brittebo; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; BMAA; neurotoxin; neurodegeneration; cellular transport; metabolic profiling; protein-association; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : β-N-methylamino-L-alanine (BMAA) is a neurotoxic non-proteinogenic amino acid produced naturally by cyanobacteria, diatoms and dinoflagellates and it has been detected in samples from fresh and marine water from all over the world. It can bioaccumulate in fish and shellfish, and has a potential to biomagnify in a terrestrial food chain. READ MORE

  5. 3. Mass-spectrometry based survey of BMAA sources, distribution and transfer

    Author : Nadezda Zguna; Leopold Ilag; Jonas Bergquist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BMAA; LC-MS MS; chiral analysis; seafood; toxins; Baltic Sea; derivatization; Analytical Chemistry; analytisk kemi;

    Abstract : β-methylaminoalanine (BMAA) is a neurotoxic non-protein amino acid first isolated from cycad seeds in 1967. It is believed to be connected to neurodegenerative diseases such as Parkinson’s, Alzheimer’s and amyotrophic lateral sclerosis (ALS) and is a ubiquitous compound produced by cyanobacteria, diatoms and dinoflagellates.

    Abstract : The cyanobacterial amino acid β-N-methylamino-L-alanine (BMAA) is a neurotoxin implicated in the etiology of neurodegenerative diseases. Cyanobacteria are cosmopolitan organisms present in various environments. READ MORE

  7. 5. Distribution and Long-term Effects of the Environmental Neurotoxin β-N-methylamino-L-alanine (BMAA) : Brain changes and behavioral impairments following developmental exposure

    Author : Oskar Karlsson; Eva Brittebo; Nils Gunnar Lindquist; Erika Roman; Sandra Ceccatelli; Uppsala universitet; []
