The properties of the bootstrap test for restrictions are studied in two versions: 1) bootstrapping under the null hypothesis, restricted, and 2) bootstrapping under the alternative hypothesis, unrestricted. This article demonstrates the equivalence of these two methods, and illustrates the small sample properties of the Wald test for testing Granger-Causality in a stable stationary VAR system by
Increased use of powerful PCR technology for the routine detection of pathogens has focused attention on the need for international validation and preparation of official non-commercial guidelines. Bacteria of epidemiological importance should be the prime focus, although a "validation infrastructure" once established could easily be adapted for PCR-based detection of viruses and parasites. The ai
While foreign direct investments (FDI) are promoted as a vehicle for economic development their environmental consequences are less established. This study tests the hypotheses that 1) FDI led to environmental degradation in form of increased greenhouse gas emissions during Sub-Saharan Africa´s recent growth spurt but that 2) this impact was felt to a lesser extent in countries with a higher quali
Values, worldviews, and self-construal are strong correlates of pro-environmental behavior. In this brief empirical note, we argue that these constructs overlap conceptually and share underlying dimensions. Using an international sample of 11,964 individuals, we demonstrate that values, worldviews, and self-construal can be reduced to two dimensions, self-focus and other-focus, capturing 67 % of v
The European Society of Endocrinology (ESE) survey reported on the largest cohort of 125 aggressive pituitary tumours (APT) and 40 pituitary carcinomas (PC). Whilst the survey focused on treatment effectiveness, all pathological data were not explored in detail. Here, we comment on some interesting pathological findings, notably the difference between APT and PC.

Bacterial infections represent a serious health care problem, and all multicellular organisms have developed defense mechanisms to eliminate pathogens that enter the host via different paths including wounds. Many invertebrates have an open circulatory system, and effective coagulation systems are in place to ensure fast and efficient closure of wounds. It was proposed early on that coagulation sy
Soft tissue sarcoma (STS) diagnostics and prognostics are challenging, particularly in highly malignant and pleomorphic subtypes such as undifferentiated pleomorphic sarcoma (UPS) and leiomyosarcoma (LMS). We applied 32K BAC arrays and gene expression profiling to 18 extremity soft tissue LMS and 31 extremity soft tissue UPS with the aim of identifying molecular subtype signatures and genomic prog
Factor H is an inhibitor of the complement system, essential for controlling the alternative pathway and also playing a crucial role in various cellular functions. In this thesis, we identified new intriguing functions of FH as a survival factor for primary human monocytes, promoting their differentiation into immunosuppressive macrophages. We showed that FH is expressed by human breast cancer cel
Four organizations at Stockholm-Arlanda airport are going through various organizational changes. They are preparing for present and future demands through structural changes, implementation of new technology, training, and other efficiency and capacity improving measures. The change processes will be followed during two years of which this paper presents the baseline measurement. The key factors
Stora förändringar och varierad elproduktion har lett till många osäkerheter i elsystemets marknader. Balanseringsverktygen har därmed hamnat i rampljuset med stor inkomstpotential idag och möjligen även långt framöver. Denna rapport visar att det finns stora möjligheter för vätgassystem och batterier att medverka på dessa marknader. En förväntad fördubbling av elproduktion under de kommande 20 årIn order to move away from fossil fuels many governments and industries are focusing their new investments in electricity and alternative fuels such as green hydrogen from electrolyzers using renewable electricity. High investment costs and electricity costs are a hindrance for the future development of a hydrogen economy which can utilize an increasing intermittent power generation. The aim of th
After electrophoresis of an alkaline extract of type 15 group A streptococci, three main precipitation lines were obtained in diffusion experiments against commercial human polyclonal IgG (lines 1, 2 and 3). Nineteen of 23 sera (83%) from apparently healthy human individuals gave line 3, while 6 of them (26%) gave line 1. The sera giving line 1 did also give line 3. Line 2 was obtained with 2 sera
The dendritic cell (DC) lineage encompasses a diverse population of cells with unique subtype-specific functions. In peripheral blood, four DC subsets have been identified based on their distinct expression of CD1c, CD141, CD16, and CD123, and these subpopulations exhibit functional properties in immune responses. However, their respective roles in allergic diseases, such as rhinitis, are unclear.
