  1. 1. Pericyte recruitment and functions in vivo. Studies of platelet-derived growth factor-B deficient embryos

    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; Mouse; gene targeting; platelet-derived growth factor; pericyte; vascular smooth muscle; angiogenesis;

    Abstract : A functional vascular system is essential for tissue growth and maintenance, and the circulatory system is therefore the first operational organ of the vertebrate embryo. In conditions of pathological tissue growth, such as tumors, formation of new blood vessels is also required, and it is anticipated that prevention of blood vessel development in those settings might ameliorate the disease progress.

    Abstract : Coral reefs belong to the most diverse and the most threatened ecosystems on earth. Anthropogenic stressors and climate change have led to mortalities at levels unprecedented in modern times. The aims of this thesis are to investigate aspects of the corals’ ability to reproduce, disperse, adapt and survive. READ MORE

  3. 3. Valence-Level Dependent Presentation-Order Effects in Preference Judgments

    Author : Mats P. Englund; Åke Hellström; William M. Petrusic; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Preference judgment; order effects; stimulus valence; sensation weighting; feature matching; comparison direction; Psychology; Psykologi; psykologi; Psychology;

    Abstract : Reversal of the stimulus-presentation order often affects the outcome in paired stimulus comparison. Psychophysicists have found that the size and direction of the order effects depend on the compared stimuli’s magnitudes, but this magnitude dependence does not seem to have been recognized previously in cognitive research on preference judgment.

    Abstract : Background: In Myocardial infarction (MI) it is well established that timely diagnosis and treatment may reduce mortality and improve the prognosis. Therefore it is important that patients with MI seek medical care as soon as possible. Patients with diabetes have a higher risk for MI and worse prognosis compared to patients without diabetes.
