  1. 1. Effects of repeated whole-body cold stress on finger temperature responses to localized cooling

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Pit Gäng; [2020]
    Nyckelord :CIVD; whole-body cold acclimation; cutaneous blood flow; immersion; thermal perception;

    Sammanfattning : The study aimed to assess whether a short-term, high-intensity cold acclimation protocol would modulate finger vasomotor [i.e., finger temperature (TF), cold induced vasodilation (CIVD)] responses and regional thermo-perception to localized cooling. LÄS MER

  3. 2. Cold-induced vasodilation in the brood patch of Zebra finches (Taeniopygia guttata)

    Kandidat-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Sofia Klubb; [2010]
    Nyckelord :Brood patch; broody; cold-induced vasodilation; mechanism; non-broody; Zebra finch;

    Sammanfattning : The development of the avian embryo is dependent of heat provisioning from the parents. To increase the heat transfer to a cooled egg the Zebra finch females develop a brood patch. Mild cooling generally constricts the blood vessels but the Arterio-venous anastomoses (AVA) in the brood patch in birds dilate. LÄS MER

  4. 3. TRP channels and regulation of blood flow in the brood patch of Zebra finches (Taeniopygia guttata)

    Kandidat-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Malin Silverå Ejenby; [2010]
    Nyckelord :4α-PDD; Brood patch; Carvacrol; TRPV3; TRPV4; Zebra finch;

    Sammanfattning : During the breeding season Zebra finch, Taeniopygia guttata, females develops a brood patch on the ventral surface which facilitates heat exchange between the incubating bird and the egg. The brood patch has to be sensitive to changes in temperature, so that the eggs can be kept at an optimal temperature for embryo development. LÄS MER

  5. 4. Vasodilatory effects of exogenous nitric oxide on the brood patch of the Zebra finch (Taeniopygia guttata)

    Kandidat-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Anna Södergren; [2010]
    Nyckelord :Arteriovenous anastomoses; AVA; brood patch; cold induced vasodilation; CIVD; nitric oxide; NO; temperature; vasodilation; Zebra finch; Taeniopygia guttata;

    Sammanfattning : In birds like the Zebra finch (Taeniopygia guttata) the female, but not the male develop a brood patch upon incubation of eggs. The brood patch functions to increase heat exchange between the bird and the eggs. Development of the brood patch includes de-feathering, increased vascularization and edema formation. LÄS MER
