  1. 1. Apnea and infection in neonates : mediatory role of interleukin-1Beta and prostaglandin E2

    Författare :Annika Olsson Hofstetter; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :respiration; interleukin-1Beta; prostaglandin E2; newborns; rodents; brainstem;

    Sammanfattning : The breathing pattern of infants, particularly preterm infants, is often irregular or periodic and is frequently interrupted by apnea The latter represents a major concern in haematology, yet much remains unknown about its incidence, appearance, and pathophysiology. This thesis further characterizes cardiorespiratory activity in preterm infants during postnatal development and investigates the association between infection and apnea in neonates, focusing on the mediatory role of interleukin-1â and prostaglandin E2 in depressing central respiration.

  3. 2. Cytokine induced airway hyperreactivity characterized in an in-vitro model of asthma

    Författare :Yaping Zhang; Klinisk och experimentell allergiforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; toxicology; Farmakologi; farmakognosi; MAPK; TNF-alpha; 5-HT; Respiratory system; Andningsorganen; Pharmacological sciences; pharmacognosy; pharmacy; interleukin-1beta; hyperresponsiveness; endothelin-1; airway; bradykinin; toxikologi; farmaci;

    Sammanfattning : Asthma is a chronic disorder of the lower airways, characterized by inflammation and hyperreactivity. Pro-inflammatory cytokines like tumour necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) are known to play important roles in the pathogenesis, but our knowledge how these cytokines contribute to the development of airway hyperreactivity is limited.

  4. 3. Biglycan as a modulator of fibrous connective tissue

    Författare :Ellen Tufvesson; allergologi och palliativ medicin Lungmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biglycan decorin fibroblast interleukin-1beta migration proteoglycan structure tumour necrosis factor-alpha; Medicine human and vertebrates ; Medicin människa och djur ;

    Sammanfattning : Fibrous connective tissue contains fibroblasts distributed in a complex network of extracellular matrix molecules, such as proteoglycans. The small proteoglycans biglycan and decorin are composed of a protein core substituted with two and one glycosaminoglycan (GAG) chain, respectively. LÄS MER

  5. 4. Effects of imidazoline compounds on intracellular CA2+ and apoptosis

    Författare :Ioulia Appelskog; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :imidazolines; imidazoline site; sulfonylurea; glucose; interleukin-1beta; insulin secretion; glucagon; somatostatin; pancreatic islets; pancreatic P-cells; HIT-T15 cells; apoptosis; cytoplasmic free Ca2 concentration;

    Sammanfattning : Cytoplasmic free Ca2+ concentration ([Ca2+]i) plays a pivotal role in the regulation of insulin release from the pancreatic beta-cell. [Ca2+]i is also important in the control of apoptosis. LÄS MER

  7. 5. Staphylococcal induced inflammatory response in human monocytes: Analysis of factors involved

    Författare :Eva Mattsson; Infektionsmedicin; []

    Sammanfattning : Purified bacterial cell wall components peptidoglycan and teichoic acid were isolated from staphylococcal species S. aureus and/or S. epidermidis and tested for their ability to induce cytokine release from plastic-adherent human monocytes. LÄS MER
