2. 1. Exploring Cancer Drugs In Vitro and In Vivo : With Special Reference to Chemosensitivity Testing and Early Clinical Development

   Author : Anne von Heideman; Peter Nygren; Bengt Tholander; Rolf Larsson; Seija Grénman; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytotoxic drug; in vitro assay; drug development; phase I clinical trial; Oncology; Onkologi; Oncology; Onkologi;

   Abstract : The aims of this thesis were to investigate the utility of in vitro drug sensitivity testing to optimize the use of cancer chemotherapy and to assess the properties of a new cancer drug in a phase I clinical trial. Tumour cells from patients were analysed with the short-term Fluorometric Microculture Cytotoxicity Assay (FMCA). READ MORE

4. 2. In silico tools in risk assessment : of industrial chemicals in general and non-dioxin-like PCBs in particular

   Author : Mia Stenberg; Patrik Andersson; Miriam Jacobs; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemometrics; industrial chemicals; in silico tools; molecular descriptors; non-dioxin-like PCBs; partial least-squares PLS ; principal component analysis PCA ; quantitative structure-activity relationship QSAR ; REACH; risk assessment RA ; statistical molecular design; structure-activity relationship SAR ;

   Abstract : Industrial chemicals in European Union produced or imported in volumes above 1 tonne annually, necessitate a registration within REACH. A common problem, concerning these chemicals, is deficient information and lack of data for assessing the hazards posed to human health and the environment. READ MORE

5. 3. Evaluation of a Miniaturized Rotating Disk Apparatus for In Vitro Dissolution Rate Measurements in Aqueous Media : Correlation of In Vitro Dissolution Rate with Apparent Solubility

   Author : Anita M. Persson; Curt Pettersson; Anders Sokolowski; Anders Karlsson; Alex Avdeef; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; analytical methods; HPLC high-performance liquid chromatography ; miniaturization; in vitro dissolution rate; apparent solubility; physicochemical properties; dissolution media; correlation study; chemometrics; Pharmaceutical chemistry; Farmaceutisk kemi; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

   Abstract : The general aim of this thesis was to evaluate a newly designed and constructed miniaturized rotating disk apparatus for in vitro dissolution rate measurements of different drug substances from all of the classes in the Biopharmaceutical Classification System (BCS). The new equipment is based on a low volume flow-through cell of Plexiglas, a gold plated magnetic bar and a special designed press. READ MORE

6. 4. Chemosensitivity in Breast Cancer

   Author : Kenneth Villman; Carl Blomqvist; Ulf Tidefelt; Nils Wilking; Uppsala universitet; []
   Keywords : Oncology; breast cancer; chemotherapy; anthracycline; predictive; topoisomerase; TOP2A; HER2; cyclin A; in vitro; Onkologi;

   Abstract : Breast cancer mortality in Sweden is now in decline, thanks to early detection and the wide use of adjuvant endocrine therapy and chemotherapy. While hormone receptor status is predictive of response to endocrine treatment, there is no clinically useful predictive marker of a patient’s response to chemotherapy. READ MORE

7. 5. Developmental Neurotoxicity Testing Using In vitro Approaches

   Author : Helena Högberg; Anna Price; Barbara Cannon; Kevin Crofton; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; Toxikologi; toxikologi; Toxicology;

   Abstract : There is a great concern about children’s health as the developing brain in foetuses and children is much more vulnerable to injury caused by different classes of chemicals than the adult brain. This vulnerability is partly due to the fact that the adult brain is well protected against chemicals by the blood brain barrier (BBB) and children have increased absorption rates and diminished ability to detoxify many exogenous compounds, in comparison to that of adults.
