  2. 16. Pathophysiology of intrauterine asphyxia

    Author : Anna-Karin Welin; Göteborgs universitet; []
    Keywords : asphyxia; ECG; endotoxemia; fetal sheep; inflammation; melatonin; periventricular leukomalacia; preterm;

    Abstract : Background: The premature infant is at increased risk of cerebral white matter damage, oftenreferred to as periventricular leucomalacia, PVL, which is associated with later developmentof cerebral palsy and cognitive impairment. The etiology of PVL remains unclear, but ischemia-reperfusion followed by generation of free radicals and intrauterine infections havebeen suggested to play an important role. READ MORE

  4. 17. Hypoxia and auto resuscitation in the neonatal rodent with special reference to the sympatho-adrenal system

    Author : Shi-Zeng Yuan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : adrenal medulla; apnea; asphyxia; autoresuscitation; catecholamines; SIDS;

    Abstract : Preterm infants exhibit irregular breathing with frequent episodes of apnea, which may be associated with cyanosis and bradycardia. Perinatal asphyxia causes a considerable amount of morbidity and mortality that occurs during early life. Studies of mechanisms responsible for perinatal asphyxia are therefore very important.

  5. 18. Transcriptional regulation in neuroblastoma cells under normoxic and hypoxic conditions

    Author : Annika Jögi; Institutionen för translationell medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; cancerology; Cytologi; onkologi; cancer; Cytology; HIF-2; HIF-1; hypoxia; Id; HES-1; bHLH; Neuroblastoma; neuronal differentiation;

    Abstract : The childhood malignancy neuroblastoma develops from early cells of the sympathetic nervous system (SNS), and the tumors often produce catecholamines. Neuroblastoma cells retain several characteristics of immature sympathetic cells including the expression of a number of transcription factors normally expressed during embryogenesis. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 20. Cerebral Hemodynamics through Intracrnial Pressure

    Author : Sima Shahsavari; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intracranial dynamics; Baroreceptor reflex; Secondary brain injury; Traumatic brain injury; Collapsible tubes; Intracranial pressure; Cushing reflex; Pulse wave propagation; Cerebral autoregulation; Cerebral compliance; Mathematical modelling;

    Abstract : Traumatic Brain Injury (TBI) continues to be a major problem worldwide. Today, intensive care of patients with TBI is mainly focused on preventing and treating secondary brain injuries. High pressure inside the intracranial cavity has been found to be an important feature of disturbed cerebral dynamics and secondary injuries. READ MORE
