    Keywords : African Trypanosomiasis; Cytokines; Chemokines; Co-stimulatory molecules; Immunopathogenesis; T.b. brucei;

    Abstract : In humans, African trypanosomiasis occurs in two forms; the chronic West African form is caused by T.b. gambiense and the acute or subacute East African form is caused by T.b. READ MORE

  4. 2. Parasite signalling and host responses in experimental and human African trypanosomiasis

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

    Abstract : 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. READ MORE

  5. 3. A role of sympathetic nervous system in immunomodulation of early experimental African trypanosomiasis

    Author : Yajuan Liu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : African trypanosomiasis or sleeping sickness is a protozoan disease prevalent in Sub-saharan Africa. It is caused by the genus Trypanosoma and occurs in humans and animals and is transmitted by infected tsetse flies. Trypanosoma brucei (T b.) rhodesiense and T b. READ MORE

  6. 4. Heat and water flows in freezing and thawing soils : numerical modelling, laboratory and field observations

    Author : Helén Engelmark; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : A laboratory study of infiltration rates into frozen and unfrozen fine sand, including temperature effects of both soil and infiltration water, is reported. The average infiltration rate varied from about 10.6 mm/min for unfrozen conditions, to about 1-2 mm/min for frozen conditions. READ MORE

  7. 5. Circadian rhythm dysfunction in the suprachiasmatic nucleus : effects of Trypanosoma brucei brucei infection and inflammatory cytokines

    Author : Gabriella B Lundkvist; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Suprachiasmatic nucleus; slice; Trypanosoma brucei; sleeping sickness; spontaneous firing; rhytm; synaptic activity; GABA; glutamate; AMPA cytokines; sleep regulation; interferon-gamma; tumor necrosis factor-alpha;

    Abstract : Alterations in the mammalian circadian pacemaker, the hypothalamic suprachiasmatic nuclei (SCN), were studied in an experimental rat model of African trypanosomiasis, or sleeping sickness, caused by infections with subspecies of Trypanosoma brucei (T b). Characteristic signs of the disease are marked disturbances in circadian rhythms, such as a fragmentation of the sleep-wake cycle. READ MORE
