Popular Abstract in Swedish Avhandlingen handlar om ett område i hjärnan som kallas amygdala. Detta området är ansvarigt för att lära sig vad man bör tycka om och vad man skall vara rädd för. I avhandlingen diskuteras hur det här området verkar fungera, och hur det arbetar tillsammans med andra områden för att göra sitt jobb. Dessa reaktioner är primitiva känslor; rädsla, lycka och så vidare. AvhaThe amygdala is a small subcortical structure that has long been implicated in the conditioning of fear and other emotions. It is heavily interconnected to a number of both cortical and subcortical structures and is thus well placed to integrate sensory inputs from multiple areas to produce emotional reactions directly as well as influence learning and attention systems. Data suggests that the amy

We evaluate a new class of rate-distortion codes based on simple linear congruential recursions. Codes are demonstrated for the memoryless Uniform, Gaussian, Laplacian and Gamma sources, whose performance often exceeds that so far reported in the literature, including that for TCQ codes. At a source coding rate of one bit per sample the performance at 512 states is 0.24 dB from the Shannon limit f

Objective: This study aimed to observe how levels of total cortisol, calculated free cortisol, corticosteroid-binding globulin, and adrenocorticotropic hormone change during the early course of human acute pancreatitis and to describe how these changes affect the development of pancreatic necrosis. Design and Patients: In a total of 109 consecutive patients with acute pancreatitis (74 with edemato

We previously reported that insulin stimulation of human platelets induces serine phosphorylation and activation of the cGMP-inhibited cAMP phosphodiesterase (cGI-PDE). Here, we describe methods to detect and partially purify an insulin-stimulated cGI-PDE kinase (cGI-PDE ISK) from lysates of platelets incubated with insulin. Incubation of human platelets with 10(-8) M insulin increased cGI-PDE ISK

Popular Abstract in Swedish Bakgrund Denna studie är en undersökning av barns musikskapande med synthesizer och dator. I studien deltog nio barn i åttaårsåldern. Musik utgör en viktig del i barns och ungdomars vardag och den stora exponering för musik som sker i vårt samhälle innebär att ingen är någon musikalisk nybörjare. Det är väl känt att barn kan skapa musik på egen hand, mest är det dock bToday’s children live in a world where music in all its different forms has become a significant factor in their everyday life. From earlier research we know that young children are able to create music by singing and using musical instruments. The present study was undertaken with eight-year-old children in school year 2 in order to investigate the children’s composing and composition processes u

Chloroplasts isolated from a plant species, Dimorphotheca pluvialis Moench (Asteraceae), grown under visible light without supplementary UV-B radiation, have poor grana development. The dominant components in the membrane organizations are doublets and triplets of stroma lamellae. However, such chloroplasts possess the capacity for electron transfer through the whole photosynthetic chain, based on

BACKGROUND: Persistent organochlorine pollutants (POPs) may interfere with reproductive function but direct evidence in humans is very limited. METHODS: Fertility was examined in four regions with contrasting blood levels of POPs. Pregnant women and their partners in Warsaw (Poland), Kharkiv (Ukraine) and Greenland were consecutively enrolled during antenatal visits. Swedish fishermen and their sp

Three isoforms of the major birch pollen allergen, Bet v, 1 from Betula verrucosa have been expressed as recombinant proteins in E. coli and purified. The immunochemical properties of recombinant isoforms (rBet v 1) differed on immunoblots when compared using Mabs and birch pollen allergic patients serum IgE. 2-D gel analysis showed that recombinant isoforms with different epitope structure can fo

A selective pressurized liquid extraction (SPLE) procedure capable of performing simultaneous extraction and clean-up has been demonstrated for multi-residue analysis of organochlorine pesticides (OCPs) in soil. The final method was performed at 100 degrees C for 3 x 10 min using acetone/n-heptane (1:1, v/v). Florisil was placed inside the extraction cell downstream the sample to remove interferin

The development of inhibitory antibodies against coagulation factor VIII (FVIII) in patients with mild haemophilia A is uncommon. We describe here two families in which three or two members have developed inhibitors, suggesting a familial predisposition. The mutations found, in the A2 (Arg593Cys) and C1 domains (Tyr2105Cys), have been reported to give rise to inhibitor development in single indivi
