  2. 1. Protective Responses to Freediving Reveal High-Altitude Tolerance

    Author : Pontus Holmström; Erika Schagatay; Angelica Lodin-Sundström; Harald K. Engan; Ola Eiken; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acclimatization; Acute Mountain Sickness; Adaptation; Apnea; Breath-hold diving; Cardiovascular diving response; High-altitude; Hypoxia tolerance; Spleen; Acklimatisering; Andhållningsdykning; Anpassning; Apné; Kardiovaskulära dykresponsen; Hög höjd; Hypoxitolerans; Hög-höjdssjukdom; Mjälte; Syrebärande kapacitet;

    Abstract : High-altitude mountaineers - just as freedivers - are exposed to hypoxia. During freediving, the diving response leads to reduced oxygen consumption, and splenic contraction increases circulating hemoglobin concentration (Hb), which enhances freediving performance. READ MORE

  4. 2. Immunomodulatory properties of steroid hormones

    Author : Maria Taube; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DTH; oestradiol; corticosteroids; T cells; SCID mice; adoptive transfer; thymus; spleen.;

    Abstract : Recent epidemiological, clinical and experimental evidence have suggested that steroid hormones play an important role in immune responses and in immune-mediated diseases. Many autoimmune diseases are treated with corticosteroids. READ MORE

  5. 3. Immunohepatotoxicity of the persistent environmental pollutants perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS)

    Author : Mousumi Rahman Qazi; Joe DePierre; Christopher Lau; Stockholms universitet; []
    Keywords : Perfluorooctanoate; Perfluorooctane sulfonate; Peroxisome proliferator-activated receptor-alpha; Hepatomegaly; Immunotoxicity; Thymus; Spleen; Biochemistry; biokemi;

    Abstract : Perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS), manufactured for a variety of industrial and consumer applications, are ubiquitous environmental pollutants. Their accumulation in humans and wildlife raises serious health concerns. Here, we examined the potential effects of PFOA and PFOS on the innate immune system in mice. READ MORE

  6. 4. Function and Regulation of B-cell Subsets in Experimental Autoimmune Arthritis

    Author : Anna-Karin E. Palm; Sandra Kleinau; Susanna Cardell; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; B cells; marginal zone; autoimmune arthritis; spleen; lymph node; antigen presentation; Fc gamma receptor IIb; complement receptors 1 and 2; mast cells; Biologi med inriktning mot molekylär immunologi; Biology with specialization in Molecular Immunology;

    Abstract : B lymphocytes play a significant role in autoimmune arthritis, with their function stretching beyond autoantibody production to cytokine secretion and presentation of autoantigen. However, the involvement and activation of different B-cell subset in the autoimmune response is not fully clear. READ MORE

  7. 5. Cardiovascular and respiratory effects of apnea in humans

    Author : Johan Andersson; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lung volume; breath-hold diving; Apnea; breath-holding; face immersion; cold stimulation; diving response; diving reflex; circulation; bradycardia; vasoconstriction; arterial blood pressure; cardiac output; spleen; respiration; splenic contraction; alveol; Physiology; Fysiologi; Respiratory system; Andningsorganen; Animal physiology; Djurfysiologi;

    Abstract : This thesis deals with cardiovascular and respiratory effects of apneas in humans. During apnea (breath-holding), a number of interacting cardiovascular reflexes are initiated, and together these reflexes are called the “diving response”. READ MORE
