2. 6. Prevalance and prevention of sexually transmitted viral infections in the Bolivian Amazonas

   Author : Marianela Patzi Churqui; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sexually transmitted infections; indigenous women; Bolivian Amazonas; medical plants; microbicides; cytokines; HSV-2; HPV; HBV;

   Abstract : This thesis investigates the prevalence of sexually transmitted viral infections in women living in the Amazonas region of Bolivia and explores whether Bolivian medical plants can affect the immune system and prevent or treat infections with Herpes simplex virus type 2 (HSV-2) and inflammation. My PhD project was financed by the Swedish International Development Cooperation Agency (SIDA), and I did my work alternately in Bolivia and in Sweden. READ MORE

4. 7. Biologically active terpenoids from Bolivian medicinal plants

   Author : Maribel Lozano Palacios; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bolivian plants; cytotoxicity; triterpenes; damsin; breast cancer;

   Abstract : Pseudo-guaianolides represent a large group of sesquiterpene lactones exhibiting significant cytotoxic and anti-inflammatory activities. Their biological activities are due to a 훼-methylene-훾-lactone unit in their chemical structure, which reacts with free sulfhydryl groups of free cysteine via a Michael-addition. READ MORE

6. 9. Bioactivity of Medicinal Bolivian Andean plants. Effects on cell proliferation and related processes

   Author : Gloria Rodrigo; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bolivian medicinal plants; colon cancer; cell proliferation; DNA synthesis; apoptosis; caspase-3; sesquiterpene; curcuphenol; damsin; coronopilin;

   Abstract : Colon cancer is common in both developed and developing countries, and is responsible for at least 600,000 deaths globally every year. It is therefore the second most common cause of cancer-related mortality. Extensive studies are being conducted worldwide to find more effective drugs that can be used in cancer treatment. READ MORE

7. 10. Antioxidant Activity of Bolivian Plant Secondary Metabolites

   Author : Patricia Mollinedo; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytoprotection; Beta-carotene; TBARS; TEAC; ABTS; antioxidant activity; secondarymetabolites; Highland plains; plants; photoprotection; Organic chemistry; Organisk kemi;

   Abstract : Certain climatologically-adverse conditions in the basin of the Poopo Lake, located on the high plateau of the Bolivian Altiplano, have prevented the existence of a reliable agricultural system and the impact on the population of the area has been severe. These problems have been the main motivation in choosing this region for this particular study. READ MORE
