   Sammanfattning : This work focuses on the design, synthesis, characterization, and application projections of low-coordinated heavy pnictogen-containing (described by the generic letter E, hence E=C) phosphaalkenes (P=C) and arsaalkenes (As=C), with emphasis on the E=C group motifs. The work aims to understand their functional and modular character, reactivity, and potential applications by stabilizing, isolating, and characterizing these species in low-coordination environments.

3. 2. Functional Dyspepsia : Symptoms and Response to Omeprazole in the Short Term

   Författare :Elisabeth Bolling-Sternevald; Hans Glise; Rein Seensalu; Linköpings universitet; []
   Nyckelord :Dyspepsia; drug therapy; omeprazole; gastrointestinal symptoms; peptic ulcer disease PUD ; malignancy; gastroesophageal reflux disease GERD ; dyspeptic symptoms; MEDICINE; MEDICIN;

   Sammanfattning : Gastrointestinal symptoms have a prevalence of 20-40% in the general adult population in the Western world. These symptoms are generally considered to be poor predictors of organic findings [e.g. peptic ulcer disease (PUD) or malignancy]. LÄS MER

4. 3. Variations in Functional Lateralization

   Författare :Peter E Wendt; Institutionen för psykologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; posterior association cortex; prefrontal; DLPFC; regional cerebral blood flow; normal subjects; lateralization; asymmetry; performance; creativity; Neurology; neuropsychology; neurophysiology; cognitive; ethanol; activation; visual stimulation; functional; verbal; divergent; spatial; Neurologi; neurofysiologi; neuropsykologi;

   Sammanfattning : The general aim of this thesis was to study asymmetric activation of the neocortex in normal subjects, using the rCBF technique and different cognitive tasks. The aim was also to study individual and group variations of asymmetric activation, as well as factors pertaining to these variations. The thesis is based on four investigations. LÄS MER

5. 4. Modeling glioblastoma heterogeneity to decipher its biology

   Författare :Yuan Xie; Lene Uhrbom; Massimo Squatrito; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioblastoma multiforme; biobank; GBM cells; cell of origin; LGR5; OPCs;

   Sammanfattning : Glioblastoma multiforme (GBM) is the most common and lethal form of primary brain tumor that mainly affects adults. GBM displays remarkable intra- and inter-tumoral heterogeneity and contains a subpopulation of cells named glioma stem cells that is believed to be responsible for tumor maintenance, progression and recurrence.

7. 5. Borderline patients in group psychotherapy : studies in process and outcome

   Författare :Dan Stiwne; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; group psychotherapy; borderline patients; therapy drop-out; group psychotherapy outcome; therapist interventions;

   Sammanfattning : Group psychotherapy with borderline patients is an activity that is fraught with ominous apprehension and it is perhaps for this reason that little research has been done in the field. The aim of the present studies was to map out the area and to test some basic hypotheses about patient and therapist behaviour during the therapy process. LÄS MER
