1. 16. Phylogenetic Studies in the Euasterids II : with Particular Reference to Asterales and Escalloniaceae

   Författare :Johannes Lundberg; Olof Ryding; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organismic biology; Organismbiologi; Organism biology; Organismbiologi; systematisk botanik; Systematic Botany;

   Sammanfattning : The present study is concerned with the evolutionary relationships among the Euasterids II, a group of angiosperms that includes the orders Apiales, Aquifoliales, Asterales, and Dipsacales together with several small, poorly known families yet unplaced as to order.Parsimony analysis of nucleotide sequence data from the chloroplast genes atpB, ndhF and rbcL together with morphological data are used to construct a phylogeny of the order Asterals, which in the present sense includes 11 families and more than 26 000 species.

   Sammanfattning : Plants have served as the principal source of medicines in different parts of the world through the ages. Herb-derived medicines have been used as decoctions, infusions, tinctures or single substance drugs. LÄS MER

5. 19. From ancient herbs to modern drugs : In search of alternatives for cancer therapy

   Författare :Wendy Soria Sotillo; Funktionell zoologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Breast cancer is the major cause of deaths related to cancer for women worldwide. Although much is known about this malignancy, extensive research is still needed to gain complete understanding of the complexity of the disease. The inter and intra tumor heterogeneity is an important trait of breast cancer. LÄS MER

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ethnobotany; fly larvae; Lao PDR; medical entomology; mosquito repellents; myiasis; plant-based insecticides; terrestrial leeches; Haemadipsidae; Systematics and phylogenetics; Systematik och fylogeni; Organism biology; Organismbiologi; Biologi med inriktning mot systematik; Biology with specialization in Systematics;

   Sammanfattning : Haematophagous parasites and disease vectors such as leeches, ticks, mites, lice, bed bugs, mosquitoes, and myiasis-causing fly larvae are common health problems in Lao Peoples Democratic Republic (Lao PDR). A main aim of my field work in Lao PDR in 2006-2010 was to document traditional knowledge among different ethnic groups about plants that people use to repel or to kill blood-feeding invertebrates.
