Hepatitis C virus and GB virus C/hepatitis G virus viremia in Swedish blood donors with different alanine aminotransferase levels

BACKGROUND: Hepatitis C virus (HCV) is a known blood-borne hepatotropic virus for which antibody screening of blood donors is universally practiced. The newly identified GB virus C (GBV-C) and its strain variant hepatitis G virus (HGV) are of unknown pathogenic significance, and screening of blood donors for this agent has not yet been implemented. Polymerase chain reaction (PCR) is the most sensi

Manorial economy and corvee labour in southern Sweden 1650-1850

This essay is an inquiry into manorial production in Scania. Its growth was dependent on the long-term development of European grain prices. When prices increased landlords were encouraged to put more land under the plough. The estates' main income came, to an increasing extent, from demesne production, which finally dominated the income profile. The peasants' most important contribution to the la

Silurian carbonate platforms and extinction events - ecosystem changes exemplified from Gotland, Sweden

Recent and ancient carbonate platforms are major marine ecosystems, built by various carbonate-secreting organisms with different sensitivity for environmental change. For this reason, carbonate platforms are excellent sensors for changes in contemporaneous marine environments. A variety of ecosystem changes in carbonate platforms have previously been recognised in the aftermath of mass extinction

Soil treatment effects on bark lesions and frost sensitivity of beech (Fagus sylvatica) in southern Sweden

Bark lesions on beech are mostly caused by frost damage and/or insect and fungal infections. Liming, treatment with wood ash and N-fertilization were hypothesised to affect this type of damage. The frost sensitivity was measured as an index of injury, calculated from electrolytic leakage of bark samples. Samples were taken from the same trees in August and November at five sites. Two sites had bee
