2. 1. 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

4. 2. Nutri-medicinal plants used in the management of HIV/AIDS opportunistic infections in western Uganda : documentation, phytochemistry and bioactivity evaluation

   Author : Savina Asiimwe; Anna Karin Borg Karlsson; Jasper Ogwal-Okeng; KTH; []
   Keywords : Ethnobotanical study; Medicinal plants; HIV; AIDS; opportunistic infections; bacteria; fungi; GC-MS; phytochemistry; SPME; antioxidant; histopathology; biochemistry; hematology; western Uganda.; Kemi; Chemistry;

   Abstract : As a result of the AIDS epidemic, many people are immunocompromised and opportunistic infections are common. Medicinal plants constitute one of the fundaments of HIV treatment and are commonly used in management of HIV–related ailments, and also to counteract the side effects of antiretroviral therapy.

5. 3. Computational Studies of UV-B Induced Signalling Pathways in Plants

   Author : Min Wu; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational Chemistry;

   Abstract : Abstract This thesis presents theoretical studies of UV-B induced signaling pathways in plants using molecular dynamic methods combined with (TD)-DFT calculations. Ultraviolet B (UV-B) radiation is a component of sunlight covering wavelengths 280-300nm. READ MORE

   Abstract : Photosynthesis is probably the most important process for allowing life to develop into the diverse forms we see today. In this process, solar radiation is used to convert CO2 into biomass. From this process, we obtain oxygen to breathe, sources of food (plant biomass), and the potential for clean and sustainable energy. READ MORE

7. 5. Antioxidants in Andean food and meals

   Author : Leslie Tejeda; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antioxidant capacity; polyphenolic compounds; anthocyanidins; individual food; meals; ans and stan genes;

   Abstract : Abstract The constant need to improve health and to prevent disease in Bolivia, especially in the Andean region with its extreme environmental conditions (high altitude and lower temperatures), motivated us to extend studies of antioxidant sources in foods and plants, since antioxidants are believed to have major health benefits. Spectrophotometric methods, such as ABTS (2, 2’- azinobis-3-ethylbenzotiazoline-6-sulfonic acid) and FRAP (ferric reduction antioxidant power), were used to evaluate antioxidant activity. READ MORE
