  2. 1. Disruption of moth mating behaviour by olfactory and auditory cues

    Author : Glenn Svensson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; ultrasound; predation risk; selection; heritability; flight tunnel; harmonic radar; pest control; mating disruption; pheromone communication; Pyralidae; Lepidoptera; Noctuidae; Animal ecology;

    Abstract : The impact of olfactory and auditory cues on the mating behaviour in two species of moths, Agrotis segetum (Noctuidae) and Plodia interpunctella (Pyralidae), was investigated to evaluate their potential use in integrated pest management. The flight behaviour of male A. READ MORE

  4. 2. Identification of single motor units in ultrafast ultrasound image sequences of voluntary skeletal muscle contractions

    Author : Robin Rohlén; Christer Grönlund; Jun Yu; Dario Farina; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultrafast ultrasound; motor units; decomposition; skeletal muscle; voluntary contractions; electromyography; twitch; imaging;

    Abstract : The central nervous system controls human force production by successive recruitment of motor units in the skeletal muscles and changing their neural firing rate. The motor unit comprises a motoneuron, its innervated muscle fibers, and its axons. READ MORE

  5. 3. Coronary heart disease in women : diagnostic and prognostic markers

    Author : Faris al-Khalili; Karolinska Institutet; Karolinska Institutet; []
    Keywords : women; coronary artery disease; diabetes mellitus; blood lipids; coronary angiography; exercise testing; intravascular ultrasound; oestrogen;

    Abstract : The main part of this thesis investigated a cohort of women younger than 66 years who had recovered from an event of acute coronary syndrome. It assessed the relationship between traditional coronary risk factors, basic clinical parameters, exercise testing results, coronary angiographic findings and recurrent cardiac events during a five-year follow up period.

    Author : Marie Jakešová; Magnus Berggren; Daniel T Simon; Fredrik Elinder; Diego Ghezzi; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The use of electronic devices in medical care is one of the main targets of precision medicine. The field of bioelectronic medicine uses electronic devices to diagnose or treat diseases and disorders in a complementary or alternative way to chemical drugs. READ MORE

  7. 5. Transesophageal Echocardiography in Patients Undergoing Elective Coronary Artery Bypass Surgery

    Author : Ingrid Palmgren; Russell Anderson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; transesophageal echocardiography; low-dose dobutamine; viability; coronary artery bypass; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; anestesiologi; Anaesthesiology;

    Abstract : Transesophageal echocardiography (TEE) has become a useful tool in monitoring the heart in patients during open-heart surgery. This study was undertaken to evaluate whether it is feasible to use TEE to assess left ventricular myocardial viability in anesthetized patients scheduled for coronary artery bypass grafting (CABG).
