2. 1. Fractional moving blood volume in fetal organs estimated using power Doppler ultrasound

   Author : Edgar Hernandez-Andrade; Lund Obstetrik och gynekologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; andrology; gynaecology; Obstetrics; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet; fetal adrenal gland; fetal lung; radionuclear microspheres; fetal lamb; perfusion; fetus; Power Doppler ultrasound; fractional moving blood volume;

   Abstract : Power Doppler ultrasound (PDU) is a sensitive technique to detect slow blood movement. The aim of the present study was to develop a standardized method for quantification of the PDU signals recorded from a specific region of interest (ROI) within fetal organs. READ MORE

4. 2. Sleep-disordered breathing in women : Associations with cardiovascular disease and the significance of sleep apnea during REM sleep

   Author : Mirjam Ljunggren; Eva Lindberg; Christer Janson; Eva Svanborg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstructive sleep apnea; REM sleep; cardiovascular disease; heart failure; Lungmedicin; Lung Medicine;

   Abstract : Background: Sleep-disordered breathing (SDB) is associated with an increased risk of cardiovascular disease, but it is unclear which elements of SDB that are most harmful to the cardiovascular system and whether the associations observed in men also apply to women.Aim: To investigate associations between different aspects of SDB and cardiovascular disease in womenMethods and results: All four papers were based on participants in “Sleep and Health in Women” (SHE), a population-based cohort study of women.

5. 3. Development in children born very preterm after intrauterine growth restriction with abnormal fetal blood flow

   Author : Eva Morsing; Lund Pediatrik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; umbilical artery; cognitive development; lung function; cardiovascular function; very preterm infants; Doppler ultrasound; Intrauterine growth restriction;

   Abstract : Delivery of fetuses with intrauterine growth restriction (IUGR) with abnormal umbilical artery blood flow in the second trimester represents a clinical dilemma. So far, no evidence based management protocols are available adressing when to deliver these fetuses. READ MORE

6. 4. Ultrasound, ions and combined modalities for increased local tumour cell death in radiation therapy

   Author : Annica Jernberg; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Focused ultrasound; ionising radiation; high-LET; cisplatin; combined modalities; cell survival; cellular effects;

   Abstract : In this thesis, new approaches to improve tumour therapy for patients with inoperable, radiation- and chemoresistant tumours were in focus. Ultrasound and ionising radiation, especially accelerated ions, are both non-invasive agents that have high precision and deep penetration in tissues, enabling increased dose to the tumour while sparing the normal tissues.

7. 5. Abdominal Aortic Wall Mechanics - Stress, Strain and Stiffness in A Medical Perspective : An Experimental Study in Man

   Author : Jerker Karlsson; Jan Engvall; Toste Länne; Jonas Stålhand; Carl-Johan Carlhäll; Magnus Cinthio; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Background:  The stiffness of the abdominal aorta is considered a significant factor affecting the morbidity and mortality of cardiovascular disease. Estimating vascular stiffness is an integral part in cardiovascular risk assessment. READ MORE
