  1. 1. Marker genes : molecular tools for in situ monitoring of bacterial distribution and activity in environmental samples

    Författare :Annika Unge; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

    Sammanfattning : Many different microorganisms carry out environmental functions, such as nutrient cycling, plant growth enhancement, or biodegradation. Some microorganisms also negatively affect their environment by causing disease. LÄS MER

  3. 2. Forests, Functions, and Food Webs : Riparian processes through an ecological and molecular lens

    Författare :Jeffery Marker; Eva Bergman; Rolf Lutz Eckstein; Denis Lafage; Rachel E. Bowes; Ann Erlandsson; John S. Richardson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Riparian systems; functional diversity; stable isotope analysis; metabarcoding; Tetragnathidae; Lycosidae; forestry management; prey subsidies; Biology; Biologi;

    Sammanfattning : Riparian systems are critical ecological interfaces that have a significant impact on the surrounding aquatic and terrestrial ecosystems. The riparian and surrounding systems have significant roles in regulating energy flow, providing essential nutrients, and supporting unique species, making them important for ecosystem function.

  4. 3. Aspect, tense and mood : Context dependency and the marker LE in Mandarin Chinese

    Författare :Marita Ljungqvist; Kinesiska; []
    Nyckelord :HUMANIORA; HUMANITIES; Chinese; Languages and literatures of South and South-East Asia; Kinesiska och språk och litteratur från Syd- och Sydostasien; pragmatics; marker; semantics; temporality; Relevance Theory; tense; mood; Mandarin Chinese; aspect;

    Sammanfattning : The grammatical marker LE in Mandarin Chinese can occur in two syntactic positions, either immediately following the verb or at the end of a sentence. Traditionally, it has been described as two homophonous but syntactically distinct morphemes, verbal LE and sentence-final LE. LÄS MER

  5. 4. Phosphatidylethanol in blood as a marker of alcohol abuse

    Författare :Arthur Varga; Associativ inlärning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PKC; MCV; ELSD; HPLC; red blood cell; phospholipase D; phosphatidylethanol; ethanol; alcohol abuse; state marker; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Biological markers offer a way of assessing ethanol intake and determining whether a health problem is alcohol related. This study investigated the use of phosphatidylethanol (PEth) in blood as a new marker of alcohol abuse. LÄS MER

  7. 5. Telomere length : dynamics and role as a biological marker in malignancy

    Författare :Ulrika Svenson; Göran Roos; Uwe Martens; Umeå universitet; []
    Nyckelord :Telomere length; peripheral blood; immune cells; breast cancer; renal cell carcinoma; biological marker; patologi; Pathology;

    Sammanfattning : Telomeres are protective structures at the end of our chromosomes, composed of multiple repeats of the DNA sequence TTAGGG. They are essential for maintaining chromosomal stability by preventing damage and degradation of the chromosome ends. LÄS MER
