Interactions of adenosine 3':5'-cyclic monophosphate (cAMP) and N-6,2'-O-dibutyryl-adenosine 3':5'-cyclic monophosphate (dbcAMP) with a lipid layer composed of monoolein-based preparation and dioleoyl phosphatidylcholine ( DOPC) were investigated by small-angle X-ray diffraction (SAXD) and Raman spectroscopy. The reversed hexagonal (H-II) MO/DOPC/H2O phase of 65:15:20 wt.% composition was selected
Abstract in French Au cours de la preacutesente eacutetude nous faisons la description systeacutematique, du point de vue neurolinguistique et interactionnel, de deux enfants de sexe feacuteminin souffrant de deacutesordres seacutemantico-pragmatiques, ces derniers formant un sous-groupe au sein du groupe des deacutesordres speacutecifiques les plus aigus du deacuteveloppement du langage. Nous avaIn the present study we provide thorough descriptions of two children with a semantic-pragmatic disorder, a subgroup within the group of specific and severe developmental language disorders, from a neurolinguistic and interactional perspective. We argue that the pragmatic problems, at least in these two girls, are most probably secondary to their semantic'conceptual deficit. If sufficient contextu
Popular Abstract in Swedish Avhandlingen undersöker naturumgängets modernisering i Förenade Arabemiraten, en federation av sju shejkdömen på den arabiska sidan av Persiska Viken. De traditionella näringarna var handel, pastoralism, fiske och pärlfiske, men dessa har sedan 1960-talet ersatts av en ekonomi baserad på export av fossila bränslen. Landet har under kort tid övergått från att vara ett trThe thesis investigates human-environmental relations in the rapidly modernizing United Arab Emirates, a federation of seven Arabian Gulf sheikhdoms. Since its establishment in 1971, the UAE has been transformed from a subsistence society based mainly on pastoralism and maritime activities (fishing, pearling, and trade) into an ultramodern society, with an economy based on the export of fossil fue
Objective: An inability of the nervous system to fully activate the muscle is one factor that can contribute to age-related muscle weakness. Superimposed electrical stimulation can be used to determine voluntary muscle activation (VA). The aim of this study was to assess VA of the quadriceps muscle in healthy older and younger subjects. Design: Electrical stimulation causes moderate discomfort in
In osteoarthritis (OA), cartilage and bone fragments have been described within the synovial tissue which are surrounded by synovial cells (i.e. detritus synovitis). These cells appear to attach actively to the cartilage and bone fragments. In rheumatoid arthritis (RA), on the other hand, synovial fibroblasts (SF) have also been shown to be localized at sites of invasion into cartilage and bone an
Abstract in French Opérant à 25 °C, on a étudié le comportement de la phase ternaire isotherme et de la structure des systèmes copolymère–eau–xylène amphiphiles de deux copolymères à trois blocs de poly(oxyde d'éthylène)–poly(oxyde de propylène) (PEO–PPO), (EO)4(PO)59(EO)4 et (EO)17(PO)59(EO)17. On a identifié les barrières des phases par RMN du 2H et par inspection sous de la lumière polarisée. OThe isothermal ternary phase behaviour and structure of amphiphilic copolymer-water-xylene systems was investigated for two poly(ethylene oxide)-poly(propylene oxide) (PEO-PPO) triblo k copolymers, (EO)(4)(PO)(59)(EO)(4) and (EO)(17)(PO)(59)(EO)(17), at 25degreesC. The phase boundaries were identified using H-2 NMR and inspection under polarized light. The microstructure and structural length scal
Background: Psychosocial resources as well as lifestyle habits during pregnancy have been shown to effect the risk of having a small-for-gestational-age (SGA) child. Most previous studies are based on a single assessment of these exposures, which does not take into account the possibility of different effects during early add late stages of pregnancy. Methods: The impact of psychosocial and lifest
Many common diseases are known to have genetic components, but since they are non-Mendelian, i.e. a large number of genetic factors affect the phenotype, these components are difficult to localize. These traits are often called complex and analysis of siblings is a valuable tool for mapping them. It has been shown that the power of the affected relative pairs method to detect linkage of a disease
To evaluate the importance of tree leafing for the start of laying and clutch size of birds, we compared the breeding phenology of great tits Parus major and blue tits P. caeruleus between one coastal and two inland sites in the same geographical region. Because of the cooling influence of the sea, trees at the coastal site were known to initiate budburst about a week later than at the inland site
The anaphylatoxic peptide C3a is a pro-inflammatory mediator generated during complement activation, whose specific G protein coupled receptor is expressed on granulocytes, monocytes, mast cells, activated lymphocytes, and in the nervous tissue. We have generated RBL-2H3 cell clones stably expressing mutants of the human C3a-receptor (C3aR) with combined alanine (Ala) substitutions of ten C-termin
Background: The rd1 mouse retina displays fast degeneration of photoreceptors resulting in a depletion of almost all rod photoreceptors by postnatal day 21 (PN21). To evaluate the role of proteinases in the pathophysiology of this animal model of retinitis pigmentosa, C3H rd1 and congenic wild-type (wt) mice retinas were analyzed. Material and Methods: The cellular localization and levels of prote
1. Climate warming increases the cover of deciduous shrubs in arctic ecosystems and herbivory is also known to have a strong influence on the biomass and composition of vegetation. However, research combining herbivory with warming is largely lacking. Our study describes how warming and simulated herbivory affect vegetation, soil nutrient concentrations and soil microbial communities after 10-13 y
The development of real-time ultrasound in the 1970's made indelible inpact on antenatal care. Assessing foetal growth and detecting deviations from normal in both growth and foetal anatomy became fesible. Expectant parents could also 'see' their foetus. Normal foetal growth parameters at term were consituted and selected parameters from the second trimester were evaluated in the detection of chro
Children in the Bolivian Andes are exposed to endemic infections and meager nourishment, and live under poor hygienic conditions. The prevention of children malnutrition is a priority in many countries including Bolivia. In this study, the health status of schoolchildren in Taraco, a Puna district, at 4,000 meters above sea level (masl) and in Caranavi, at 650 masl in the wealthier subtropical val
Eye movements during regular reading, thorough reading, skimming, and spell checking of single pages of text were measured, to investigate how high-level reading tasks elicited by instructions affect reading behavior. Word frequency and word length effects were found. All results were compared to regular reading. Thorough reading involved longer total reading times and more rereading, and resulted
Trots den snabba utvecklingen av moderna tekniker för narkos och bedövning upplever många patienter smärta efter kirurgi. God smärtlindring efter en operation kan påskynda återhämtningen och därmed minska risken för komplikationer som blodpropp eller infektion. För att uppnå detta måste vi bli bättre på att hitta individer med ökad risk för postoperativ smärta redan innan de sövs. Sedan tidigare kMany patients experience pain after surgery. Postoperative pain may lead to delayed mobilization, persisting pain, and psychosocial distress. Others are given excessive analgesic doses and experience side effects. More optimal use of pain relief has several advantages, such as faster postoperative mobilization and fewer incidents of venous thromboembolism or infection. To achieve this, we must ide
The aqueous self-assembly behavior of the dyes Quinaldine red acetate and Pyronin Y in a wide range of concentrations is reported here for the first time. 1H NMR spectroscopy, polarized-light optical microscopy, and small and wide X-ray scattering were used to get insight into molecular interactions, phase boundaries and aggregate structure. Quinaldine red acetate and Pyronin Y self-organize into
The purpose of this study was to clarify the causes of the smoking-schizophrenia association.
