  1. 11. Perinatal nicotine exposure. Effects on the defense against hypoxia in lambs

    Författare :Ola Hafström; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carotid body; nicotine; prenatal exposure delayed effects; respiration; respiratory mechanics; sudden infant death; smoking; tobacco;

    Sammanfattning : The aim of the present study was to evaluate whether perinatal nicotine exposure could impair cardiorespiratory defense mechanisms to hypoxia. The rationale for this approach is that exposure to tobacco smoke, particularly before birth, is a risk factor for the sudden infant death syndrome as well as for obstructive airway disease in childhood.

  3. 12. Screening for Atherosclerosis with Magnetic Resonance Imaging and Ultrasound

    Författare :Christina Lundberg; Lars Johansson; Håkan Ahlström; Lars Lind; Anders Wanhainen; Hansen Tomas; Kenneth Caidahl; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Atherosclerosis is a major cause of death and disability worldwide. Although traditional risk factors can identify the healthy or severely affected individuals, sudden lethal outcome is still frequent in those suggested as intermediate in risk for cardiovascular events (CVE).

  4. 13. Diastolic left ventricular filling in 50-year-old male and female adults : Evaluation by Doppler echocardiography

    Författare :Toomas Kangro; Uppsala universitet; []
    Nyckelord :Medical sciences; Arterial distensibility; diastole; Doppler echocardiography; exercise; healthy persons; hypertension; LV filling; menopause; medicin; vård; MEDICINE; MEDICIN; Clinical Physiology; Klinisk fysiologi;

    Sammanfattning : Left ventricular (LV) diastolic filling abnormalities are seen in many patients with various cardiac disorders. Age is an important determinant of Doppler indices of LV diastolic filling. LÄS MER

  5. 14. Hyperemic Brachial Artery Blood Flow Velocity

    Författare :Susann J Järhult; Lars Lind; Johan Sundström; Peter Friberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN; Cardiovascular medicine; Kardiovaskulär medicin; Medicinsk vetenskap; Medical Science;

    Sammanfattning : This thesis aims to evaluate the blood flow velocity in the Brachial artery during reactive hyperemia. Primarily to appraise the information it might contain regarding cardiovascular function and cardiovascular risk. LÄS MER

  7. 15. The role of bacterial endotoxin in the immature brain

    Författare :Saskia Eklind; Göteborgs universitet; []
    Nyckelord :lipopolysaccharide; hypoxia-ischemia; immature; temperature; cerebral blood flow; blood glucose; inflammation; apoptosis; microarray; preconditioning;

    Sammanfattning : Aim: Epidemiological evidence suggests that infections may increase the vulnerability of the immature brain to further insults. The aim of this thesis was to investigate the role of bacterial endotoxin (lipopolysaccharide, LPS) on hypoxic-ischemic (HI) injury in the immature rat brain, and to evaluate possible underlying mechanisms of increased sensitivity.
