  2. 1. Cannabinoids as modulators of cancer cell viability, neuronal differentiation, and embryonal development

    Author : Sofia Gustafsson; Stig Jacobsson; Birgitta Sander; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cannabinoids; cell viability; neuronal differentiation; colorectal cancer; chick embryo; biokemisk farmakologi; biochemical pharmacology; Toxicology; toxikologi;

    Abstract : Cannabinoids (CBs) are compounds that activate the CB1 and CB2 receptors. CB receptors mediate many different physiological functions, and cannabinoids have been reported to decrease tumor cell viability, proliferation, migration, as well as to modulate metastasis. READ MORE

    Abstract : A nonparametric population approach is now accessible to a more comprehensive network of modelers given its recent implementation into the popular NONMEM application, previously limited in scope by standard parametric approaches for the analysis of pharmacokinetic and pharmacodynamic data. The aim of this thesis was to assess the relative merits and downsides of nonparametric models in a nonlinear mixed effects framework in comparison with a set of parametric models developed in NONMEM based on real datasets and when applied to simple experimental settings, and to develop new diagnostic tools adapted to nonparametric models.

    Abstract : Background Animal models can be used to mimic human conditions of psychopathology, and also as pre-clinical models to evaluate candidate drugs. With hormonal treatment it is possible to produce behavior in the rat which corresponds to the mental symptoms of pre-menstrual syndrome (PMS), and pre-menstrual dysphoric disorder (PMDD). READ MORE

  6. 4. Spontaneous reporting of adverse drug reactions : Possibilities and limitations

    Author : Martin Bäckström; Tom Mjörndal; Rune Dahlqvist; Folke Sjökvist; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; adverse drug reactions; spontaneous reporting; metamizole; general practitioners; hospital physicians; under-reporting; economical inducement; nurses.; Farmakologi; Pharmacological research; Farmakologisk forskning; Clinical Pharmacology; klinisk farmakologi;

    Abstract : Adverse drug reactions (ADRs) constitute a major problem in society and in drug therapy. They are a common cause of short-term hospitalization, prolonged hospitalization and death. Spontaneous reporting of ADRs remains one the most effective methods for detecting new and serious drug reactions. READ MORE

  7. 5. Transcription Factor AP-2 in Relation to Serotonergic Functions in the Central Nervous System
