From sign to action : studies in chimpanzee pictorial competence. : Studies in chimpanzee pictorial competence

Many studies of children and apes realized in psychology address issues that are highly relevant to semiotics, but they often do so indirectly, or they use a terminology that is confusing and/or too vague from a semiotical point of view. The studies reported here, however, follow the paradigm of these psychological studies, but they are couched in an explicit semiotical terminology. They involve t

Subtrochanteric fractures after long-term treatment with bisphosphonates: a European Society on Clinical and Economic Aspects of Osteoporosis and Osteoarthritis, and International Osteoporosis Foundation Working Group Report

This paper reviews the evidence for an association between atypical subtrochanteric fractures and long-term bisphosphonate use. Clinical case reports/reviews and case-control studies report this association, but retrospective phase III trial analyses show no increased risk. Bisphosphonate use may be associated with atypical subtrochanteric fractures, but the case is yet unproven. A Working Group o

Dermatan Sulfate-Free Mice Display Embryological Defects and Are Neonatal Lethal Despite Normal Lymphoid and Non-Lymphoid Organogenesis.

The epimerization of glucuronic acid into iduronic acid adds structural variability to chondroitin/dermatan sulfate polysaccharides. Iduronic acid-containing domains play essential roles in processes such as coagulation, chemokine and morphogen modulation, collagen maturation, and neurite sprouting. Therefore, we generated and characterized, for the first time, mice deficient in dermatan sulfate e

Low-loss light transmission in a rectangular-shaped hybrid metal trench at 1550 nm

A hybrid plasmonic waveguide consisting of a high-index dielectric core embedded inside a rectangular-shaped metallic trench is proposed and its guiding properties are investigated at the wavelength of 1550 nm. Numerical simulations based on the finite element method have demonstrated that the introduced dielectric core could greatly reduce the modal loss of the metal trench while maintaining stro

Using Reference Attribute Grammar-Controlled Rewriting for Energy Auto-Tuning

Cyber-physical systems react on events reported by sensors and interact with objects of the real world according to their current state and their view of the world. This view is naturally represented by a model which is continuously analysed and updated at runtime. Model analyses should be ideally concise and efficient, requiring well-founded, comprehensible implementations with efficient reasonin

The effect of mixed liquor suspended solids (MLSS) on biofouling in a hybrid membrane bioreactor for the treatment of high concentration organic wastewater

Biofouling is a crucial factor in membrane bioreactor (MBR) applications, particularly for high organic loading operations. This paper reports a study on biofouling in an MBR to establish a relationship between critical flux, J(c), mixed liquor suspended solids (MLSS) (ranging from 5 to 20 g L-1) and volumetric loading rate (6.3 kg COD m(-3) h(-1)) of palm oil mill effluent (POME). A lab-scale 100

Beneficial effects of a Paleolithic diet on cardiovascular risk factors in type 2 diabetes: a randomized cross-over pilot study

Background: Our aim was to compare the effects of a Paleolithic ('Old Stone Age') diet and a diabetes diet as generally recommended on risk factors for cardiovascular disease in patients with type 2 diabetes not treated with insulin. Methods: In a randomized cross-over study, 13 patients with type 2 diabetes, 3 women and 10 men, were instructed to eat a Paleolithic diet based on lean meat, fish, f

Hemoglobin adducts as a measure of variations in exposure to acrylamide in food and comparison to questionnaire data

Measurement of haemoglobin (Hb) adducts from acrylamide (AA) and its metabolite glycidamide (GA) is a possibility to improve the exposure assessment in epidemiological studies of AA intake from food. This study aims to clarify the reliability of Hb-adduct measurement from individual single samples for exposure assessment of dietary AA intake. The intra-individual variations of AA- and GA-adduct le

The role of N-cadherin and S1P/S1P1 in pancreas development

Popular Abstract in Swedish β-celler producerar insulin som frisätts när blodsockret höjs, t.ex. efter en måltid. Patienter med diabetes saknar de insulinproducerande β-cellerna eller har nedsatt känslighet för insulin. För de patienter som saknar insulin kan det vara svårt att reglera blodsockernivåerna i blodet trots dagliga injektioner med insulin, varför transplanterbara insulinproducerande β-Organogenesis of epithelial organs requires interaction between epithelial and mesenchymal tissues. During pancreas development, mesenchyme-derived structures induce specification, growth and differentiation of pancreatic epithelial cells. For instance, notochord, endothelial cells, and pancreatic mesenchyme are essential for the development of the pancreas. N-cadherin deficient-embryos suffer fro

Path Dependence Research in Regional Economic Development: Cacophony or Knowledge Accumulation?

Henning M., Stam E. and Wenting R. Path dependence research in regional economic development: cacophony or knowledge accumulation, Regional Studies. The concept of path dependence has gained momentum in the social sciences, particularly in economic geography. This paper explores the empirical literature on path dependence and path creation in regional economic development. It offers a critical ref

Retoriken efter Retoriken: Från Aristoteles till retorikämnet idag

Den brittiske filosofen och matematikern Alfred North Whitehead har i ett av sina mer berömda citat sagt att den västerländska filosofihistorien är en serie fotnoter till Platon. På samma sätt kan retorikhistorien sägas vara en serie fotnoter till Aristoteles Retorik. När nu detta inflytelserika verk för första gången finns tillgängligt på svenska kan det vara på sin plats att säga något om detta

Enrichment of Murine CD68(+)CCR2(+) and CD68(+)CD206(+) Lung Macrophages in Acute Pancreatitis-Associated Acute Lung Injury.

Acute lung injury (ALI) is an important cause of mortality in critically ill patients. Acute pancreatitis (AP) is one of the risk factors for developing this syndrome. Among the inflammatory cells, macrophages have a key role in determining the severity of the acute lung injury. In the lungs, macrophages constitute a heterogeneous cell population distributed in different compartments. Changes in n

Does Economic Freedom Foster Tolerance?

Abstract in UndeterminedTolerance has the potential to affect both economic growth and wellbeing. It is therefore important to discern its determinants. We contribute to the literature by investigating whether the degree to which economic institutions and policies are market-oriented is related to different measures of tolerance. Cross-sectional and first-difference regression analysis of up to 69

Genetic Characterization of Pediatric T-cell Acute Lymphoblastic Leukemia

The aim of my thesis has been to characterize genetically pediatric T-cell acute lymphoblastic leukemia (T-ALL). Articles I and II focus on molecular characterization of translocations involving T-cell receptor (TCR) loci. These types of aberration are characteristic for T-ALL and have previously proved pivotal in the identification of genes implicated in leukemogenesis. The translocation t(12;14

A meta-analysis of genome-wide association studies identifies novel variants associated with osteoarthritis of the hip

Objectives Osteoarthritis (OA) is the most common form of arthritis with a clear genetic component. To identify novel loci associated with hip OA we performed a meta-analysis of genome-wide association studies (GWAS) on European subjects. Methods We performed a two-stage meta-analysis on more than 78 000 participants. In stage 1, we synthesised data from eight GWAS whereas data from 10 centres wer

Curvature-Based Regularization for Surface Approximation

We propose an energy-based framework for approximating surfaces from a cloud of point measurements corrupted by noise and outliers. Our energy assigns a tangent plane to each (noisy) data point by minimizing the squared distances to the points and the irregularity of the surface implicitly defined by the tangent planes. In order to avoid the well-known "shrinking" bias associated with first-order

Experiences from the implementation of structured patient discharge information for safe medication reconciliation at a Swedish university hospital

Study objectives: A method for medication reconciliation that reduces medication errors and healthcare contacts when a patient is discharged from hospital, LIMM-DI (Lund integrated medicines management-discharge information) had been previously developed by the authors. LIMM-DI is structured information written for the patient and sent to the next caregiver. In this study, the use (implementation

Health financing for the poor produces promising short-term effects on utilization and out-of-pocket expenditure: evidence from Vietnam

Background: Vietnam introduced the Health Care Fund for the Poor in 2002 to increase access to health care and reduce the financial burden of health expenditure faced by the poor and ethnic minorities. It is often argued that effects of financing reforms take a long time to materialize. This study evaluates the short-term impact of the program to determine if pro-poor financing programs can achiev

Energy, conflict and war: Towards a conceptual framework

It is widely recognised that the presence of some fossil fuels and their transport routes can affect the risk of conflicts. Other parts of the energy system and contextual conditions (social, economic or political factors) also matter for such conflicts, but which and how is not as well researched. This paper develops a framework that links characteristics of energy systems with contextual conditi
