We explore here, through three complementary experiments on virtual objects, how intimate active relations with multisensory audio-visual and haptics perceptions allow to the cognitive creation of new believable and plausible objects that can be different of the virtual ones objectively implemented. The three experiments are based on "Pebble Boxes" and consist in the exploration and the manipulati
In recent years the importance of strong brands has come very much into focus both among theoreticians and practitioners. In order to gain a better understanding of the nature of brand strength, I have chosen to analyse the branding process. The overriding aim of this analysis is to develop a theoretical framework and typology with which to facilitate our understanding of how powerful brands can b
BACKGROUND AND AIMS: Helicobacter pylori is the major causative agent in peptic ulcer disease and is strongly implicated in the development of gastric cancer. It has also been linked, less strongly, to cardiovascular disease. The mechanisms by which certain Strains of H pylon induce platelet aggregation through interactions with platelet glycoprotein 1b have been previously described. METHODS: In
Popular Abstract in Swedish Denna avhandling beskriver studier av de mekanismer varmed bakterien Streptococcus pyogenes undviker komplementdeposition och fagocytos.Phagocytosis of Streptococcus pyogenes is complement dependent. However, the cell wall-associated M protein, which exists in >100 different serotypes (M types), enables the bacteria to evade phagocytosis. To analyze the mechanisms by which M protein confers this ability we used, as model systems, two representative M proteins, the M22 and M5 proteins, which have properties typical for many M prote
Chronic treatment with epidermal growth factor (EGF) stimulates growth of all wall layers of the urinary tract in pigs and rats. Herein, we investigated the acute effects of EGF on detrusor smooth muscle activity. For in vivo examination, awake rats received EGF (75 micrograms/kg) intravenously and detrusor smooth muscle activity was monitored cystometrically. The EGF bolus caused no alteration in
We present calculations on the atomic delay in photoionzation obtained with different combinations of linearly and circularly polarized light, and show how a tensor operator approach can be used to readily obtain results for any combination from a single calculation of the radial integrals. We find that for certain choices of polarization and detection geometry a single time-delay measurement is e
Purpose: Since 2006, higher education institutions (HEIs) in Sweden, should according to the Higher Education Act, promote sustainable development (SD). In 2016, the Swedish Government asked the Swedish higher education authority to evaluate how this study is proceeding. The authority chose to focus on education. This paper aims to produce a report on this evaluation. Design/methodology/approach:
Serum amyloid A (SAA) is a well-described acute phase protein induced during the acute phase response (APR) to infection. Four isoform specific genes are found in most mammals. Depending on species, SAA3 and SAA4 are ge0nerally preferentially expressed extrahepatically whereas SAA1 and SAA2 are hepatic isoforms dominating the SAA serum pool. Little is known about how specific infections affect the
Acute leukemia refers to a group of aggressive hematological malignancies of myeloid and lymphoid lineages termed acute myeloid leukemia (AML) and acute lymphoid leukemia (ALL) respectively. Acute leukemia is characterized by the presence of underlying genetic aberrations which alter the biology of normal hematopoietic cells resulting in the accumulation of immature abnormally differentiated blast
Experiencing symptoms after heart transplantation may hamper the heart recipient’s self-management which can lead to negative effects. We know little about symptom occurrence and distress after heart transplantation, especially in relation to sociodemographic variables. The aim of the study was to explore self-reported symptom occurrence and distress after heart transplantation and their relations
1. Helodermin, helospectin I and helospectin II, peptides recently isolated from the salivary gland venom of Heloderma suspectum, were compared to vasoactive intestinal peptide (VIP) with respect to effects on systemic blood pressure and on isolated femoral arteries in the rat. 2. They all reduced blood pressure in a dose-dependent manner; helodermin was less effective than VIP. However, at doses
Body weight has been shown to be a predictor of clinical progression in Huntington's disease (HD). Alongside widespread neuronal pathology, both HD patients and the R6/2 mouse model of HD exhibit weight loss and increased energy expenditure, providing a rationale for targeting whole-body energy metabolism in HD. Leptin-deficient mice display low energy expenditure and increased body weight. We the
Background: Attention-deficit hyperactivity disorder (ADHD) is a common and impairing neurodevelopmental disorder. The Cambridge Neuropsychological Test Automated Battery (CANTAB) is a computerized test battery with standardized procedures and solid psychometric properties targeting multiple neuropsychological functions. Aims: The aim of this study was to look at the effects of ADHD on cognitive p
BACKGROUND: Perfluoroalkyl substances (PFAS) are stable chemicals used in various applications. PFAS exposure has been associated with lower birth weight and immunological effects in children, and limited evidence further suggests adverse neurodevelopmental effects. Previous studies show that PFAS cross the placental barrier during pregnancy leading to prenatal exposure of the fetus. Research on t
Purpose: The purpose of this case-control study was to investigate the associations between maternal serum concentrations of vitamin D early in pregnancy and the occurrence of preterm birth. Methods: The study included 269 women (cases) whose children were born preterm (< 37 gestational weeks [gw]) and 332 women (controls) whose children were born term (≥ 37 gw). Among the cases, 59 were extreme p
We investigated the role of cultural experience in the search advantage for happy faces. European British participants living in the UK, Asian Japanese participants living in Japan, and Asian Japanese participants living in the UK, were required to search for a happy or an angry face target against a background of neutral facial expressions, using Asian Japanese and European American faces. Result
This study examines the multidimensional conflicts arising from land commodification through second-home development in Ziarat village, Iran, addressing a critical research gap in developing rentier states. Employing grounded theory methodology with data from 75 stakeholder interviews, the research identifies conflicts at individual-individual, individual-institutional, and institutional-instituti
