1. Fate and transport of POPs in the aquatic environment : with focus on contaminated sediments
Sammanfattning : Persistent organic pollutants (POPs) are hydrophobic substances that readily sorb to organic matter in particles and colloids instead of being freely dissolved in the water phase. This sorption affects the bioavailability and environmental transport of the POPs. LÄS MER
2. Assessment of organochlorine contamination in the aquatic environment of Latvia with perch and heron as biomarkers
Sammanfattning : Polychlorinated biphenyls (PCBs), DDT, DDT transformation products, and several other organochlorine substances (OCS) have been analysed in numerous species and matrices from different parts of the world including Arctic environments. However, knowledge on levels and distribution of OCS is still lacking for many regions world-wide including the Eastern Europe in general. LÄS MER
3. Role of tartrate-resistant acid phosphatase in bone remodeling
Sammanfattning : Tartrate-resistant acid phosphatase is a metalloenzyme that exists as two isoforms: the monomeric TRAP 5a and the proteolytically cleaved TRAP 5b, responsible for phosphatase activity, which is highly expressed in osteoclasts (OCs). TRAP 5b has been used as a serum marker of bone resorption, as it correlates with the absolute number of OCs and with resorption markers such as CTX-I. LÄS MER
4. Early trauma/dysmorphogenesis and adult neurodysfunction in schizophrenia
Sammanfattning : To measure the importance of early neurodevelopmental disturbance for schizophrenia, early trauma and dysmorphogenesis (i.e. obstetric complications (OCs), minor physical anomalies (MPAs), head circumference (HC) and dermatoglyphic characteristics) were studied in relationship to adult neurodysfunction (i.e. LÄS MER
5. Early life risk factors for schizophrenia - studies of foetal and perinatal complications
Sammanfattning : Background: Despite intensive research for decades the causes of schizophrenia are largely unknown. A major lead in scientific work is the neurodevelopmental hypothesis i.e. a vulnerability for the illness is believed to be caused by developmental defects of the CNS during foetal life or childhood.
