Spontaneous lung and lymph node metastasis in transgenic breast cancer is independent of the urokinase receptor uPAR

Urokinase-type plasminogen activator (uPA) is an extracellular protease that plays a pivotal role in tumor progression. uPA activity is spatially restricted by its anchorage to high-affinity uPA receptors (uPAR) at the cell surface. High tumor tissue expression of uPA and uPAR is associated with poor prognosis in lung, breast, and colon cancer patients in clinical studies. Genetic deficiency of uP

Impaired CXCR1-dependent oxidative defence in active tuberculosis patients.

Much of the pronounced host inflammatory response that occurs in tuberculosis (TB) is related to failed immunity against the invading pathogen. The G-protein coupled receptors CXCR1 and CXCR2 are implicated in important signal transduction pathways in lung inflammatory responses. We investigated the expression and function of these receptors in a simple whole blood model from 24 patients with pulm

Inhibition of splicing by serine-arginine rich protein 55 (SRp55) causes the appearance of partially spliced HIV-1 mRNAs in the cytoplasm

We have previously shown that SRp55 inhibits splicing from HIV-1 exon 3, thereby generating partially spliced mRNAs encoding HIV-1 vpr. Here we show that SRp55 also inhibits splicing from HIV-1 exon 5 to generate HIV-1 vpu/env mRNA, albeit with lower efficiency. We also show that inhibition of HIV-1 splicing by SRp55 causes the appearance of partially spliced vpu, env and vpr mRNAs in the cytoplas

Identification of the molecular and genetic basis of PX2, a glycosphingolipid blood group antigen lacking on globoside-deficient erythrocytes.

The x2 glycosphingolipid is expressed on erythrocytes from individuals of all common blood group phenotypes and elevated on cells of the rare P/P1/P(k)-negative p blood group phenotype. Globoside or P antigen is synthesized by UDP-N-acetylgalactosamine:globotriaosylceramide 3-β-N-acetylgalactosaminyltransferase encoded by B3GALNT1. It is the most abundant non-acid glycosphingolipid on erythrocytes

Conditional Cash Transfers and Social Mobility: The Role of Asymmetric Structures and Segmentation Processes

This article seeks to advance existing research on conditional cash transfers (CCTs) by centring the analysis of their long-term impact on the reproduc- tion of poverty and exclusion. To date, most analyses and assessments of CCTs’ long-term impact have been based on simulations focused on specific parameters such as income changes and educational attainment. This study takes as its starting point

The problem of confounding in studies of the effect of maternal drug use on pregnancy outcome.

In most epidemilogical studies, the problem of confounding adds to the uncertainty in conclusions drawn. This is also true for studies on the effect of maternal drug use on birth defect risks. This paper describes various types of such confounders and discusses methods to identify and adjust for them. Such confounders can be found in maternal characteristics like age, parity, smoking, use of alcoh

Do competition authorities consider business relationships?

Abstract in Undetermined Purpose: Companies engage in business relationships for a variety of reasons, including specialization, product development, and building competitive networks. Research has demonstrated that mergers and acquisitions (M&As) may challenge ongoing business relationships. The purpose of this article is to investigate whether and how competition authorities consider busines

Experimental Models for the Study of Female and Male Sexual Function

Introduction. Significant progress has been made in the understanding of physiological and pharmacological mechanisms of human sexual functioning through preclinical research in animal models. Aim. To provide an evidence-based documentation of the experimental models evaluating male and female sexual function for useful clinical translation. Methods. Consensus discussion over the past 18 months le

Extravascular lung water index improves the diagnostic accuracy of lung injury in patients with shock

Introduction: The diagnosis of acute lung injury (ALI) may be more robust if more accurate physiological markers can be identified. Extravascular lung water (EVLW) is one possible marker, and it has been shown to correlate with respiratory function and mortality in patients with sepsis. Whether EVLW confers diagnostic value in a general population with shock, as well as which index performs best,

Permanent Genetic Resources added to Molecular Ecology Resources Database 1 December 2009-31 January 2010

Loci were developed for the following species: Allanblackia floribunda, Amblyraja radiata, Bactrocera cucurbitae, Brachycaudus helichrysi, Calopogonium mucunoides, Dissodactylus primitivus, Elodea canadensis, Ephydatia fluviatilis, Galapaganus howdenae howdenae, Hoplostethus atlanticu

The effect of hydrogen bonding on torsional dynamics: A combined far-infrared jet and matrix isolation study of methanol dimer.

The effect of strong intermolecular hydrogen bonding on torsional degrees of freedom is investigated by far-infrared absorption spectroscopy for different methanol dimer isotopologues isolated in supersonic jet expansions or embedded in inert neon matrices at low temperatures. For the vacuum-isolated and Ne-embedded methanol dimer, the hydrogen bond OH librational mode of the donor subunit is fina

Personalised, predictive and preventive medicine: a decision-theoretic perspective

Background. The last decade has witnessed remarkable developments in medical treatment that is personalised, predictive and preventive. The advances made here have the potential to bring about radical change, not only in diagnostic tests and prescriptions, but also in more fundamental patterns in the provision of health care. Methods. The conceptual framework and principles of modern decision theo

Camouflage effectiveness of static nets in SAR images

We present a methodology to determine the camouflage effectiveness of static nets in a SAR image. There is currently no common recognized methodology within the signature management community in this research topic. One step towards establishing a common methodology is to use a standardized target to be camouflaged. We use the STANdard Decoy for CAmouflage Materials (STANDCAM) target developed by

Sustainable Development in a Globalized World

In this special issue of the Journal of Environment and Development, we present results from the research project Globalisation Informed by Sustainable Development (GLOBIS), 2009-2014, funded by the European Union Framework Programme 7. Starting from and focusing on international policies on agriculture, energy, innovation, migration, and transport at both European Union and global levels, the dua
