  1. 16. Parasite signalling and host responses in experimental and human African trypanosomiasis

    Författare :Maha Hamadien; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :TLTF; anti-TLTF antibodies; IFN-gamma; Human African trypanosomiasis; T b. brucei; ;

    Sammanfattning : African trypanosomiasis or sleeping sickness is a disease of tropical Africa caused by the unicellular-flagellated protozoan parasite, Trypanosoma brucei (T b.), which is transmitted by its insect vector, the tsetse fly. In humans, there are two forms of the disease: a chronic form in West and Central Africa, caused by T. b. LÄS MER

  3. 17. Neuropeptides Related to Tachykinins and Leucokinins in the Developing Nervous System of Insects

    Författare :Kim Min Yung; Karoly Elekes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoologi; Zoology;

    Sammanfattning : In insects more than 300 neuropeptides have been identified and these have been implicated in a vast range of functional roles. These peptides have been grouped into families based on amino acid sequence similarities. LÄS MER

  4. 18. Spatial Vision in Bees : Behavioural investigation of spatial resolution and contrast sensitivity

    Författare :Aravin Chakravarthi; Funktionell zoologi; []
    Nyckelord :Insect vision; Honeybees; Bumblebees; Spatial resolution; Contrast sensitivity; Motion detection; Object discrimination;

    Sammanfattning : Bees use multiple sensory modalities to perform day-to-day tasks. Light allows them to perceive objects and the general features of their surroundings, enabling them to find food and to navigate safely across the landscape. LÄS MER

  5. 19. Single-cell RNA sequencing as a tool to study panarthropod evolution

    Författare :Brenda Irene Medina Jimenez; Ralf Janssen; Graham Budd; Tatjana Haitina; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Single-cell RNA sequencing; EvoDevo; gene expression; tissue dissociation; cell capture; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Panarthropoda is a monophyletic group comprised of arthropods and lobopods, molting animals with a segmented body, paired appendages, dorsal brain, and ventral nerve cords. Evolutionary Developmental Biology (EvoDevo) is an interdisciplinary field that seeks to understand how changes in development form the basis for variations in morphology and phenotypic evolution, including the genetic network underlying these processes.

  7. 20. Regulation of gene expression by non-protein-coding RNAs

    Författare :Mohammad Ali Faghihi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The human genome sequencing projects revealed that the human genome contains over 3 billion DNA base pairs, but only 20,000 25,000 protein-coding genes. In fact, only about 1.2% of the genome codes for proteins. LÄS MER
