BACKGROUND: The CD44 cell adhesion molecule is aberrantly expressed in many breast tumors and has been implicated in the metastatic process as well as in the putative cancer stem cell (CSC) compartment. We aimed to investigate potential associations between alternatively spliced isoforms of CD44 and CSCs as well as to various breast cancer biomarkers and molecular subtypes. METHODS: We used q-RT

Quantitative investigation of insect activity in their natural habitat is a challenging task for entomologists. It is difficult to address questions such as flight direction, predation strength, and overall activities using the current techniques such as traps and sweep nets. A multispectral kHz remote detection system using sunlight as an illumination source is presented. We explore the possibili

This study examines the exposure of the members of supplier networks to two layers of social influences. First, as the network connects an actor to a foreign constellation, the actor faces influences of a global character. Second, each individual actor experiences different forces emanating from its indigenous institutional environment. The exposure to two institutional practices presents a conund

Context. NGC 4815 is a populous similar to 500 Myr open cluster at R-gc similar to 7 kpc observed in the first six months of the Gaia-ESO Survey. Located in the inner Galactic disk, NGC 4815 is an important potential tracer of the abundance gradient, where relatively few intermediate age open clusters are found. Aims. The Gaia-ESO Survey data can provide an improved characterization of the cluster

The production of W bosons in association with two jets in proton-proton collisions at a centre-of-mass energy of root s = 7 TeV has been analysed for the presence of double-parton interactions using data corresponding to an integrated luminosity of 36 pb(-1), collected with the ATLAS detector at the Large Hadron Collider. The fraction of events arising from double-parton interactions, f(DP)((D)),

Popular Abstract in Swedish En ordentlig bildning av det centrala nervsystemet är viktigt för ett nyfött barn eller en vuxen. Den senaste tidens kartläggning av människans arvsmassa har lett till identifiering av ungefär 23000 gener, många av dem aktiva i det utvecklande nervsystemet. Men lite är känt om deras funktion och hur de samverkar för att påverka utvecklingen av organ så komplexa som den Morphogens such as Hedghog, Wnt, FGF, and retinoic acid are important signals whose concentrations need to be tightly regulated in the vertebrate embryo to ensure body axis development and formation of the central nervous system. We first show that the intracellular cytoplasmic protein XSufu acts as a dual regulator of Hedgehog (Hh) and Wnt signals during neural induction and patterning in the Xen

The effects of Li deposition on hydrogenated bilayer graphene on SiC(0001) samples, i.e. on quasi-freestanding bilayer graphene samples, are studied using low energy electron microscopy, micro-low-energy electron diffraction and photoelectron spectroscopy. After deposition, some Li atoms form islands on the surface creating defects that are observed to disappear after annealing. Some other Li atom

A label-free immunosensor for the direct detection of cholera toxin (CT) at sub-attomolar level has been developed based on potential-step capacitance measurements. Anti-CT antibody was adsorbed on gold nanoparticles (AuNPs) incorporated on a polytyramine-modified gold electrode. The concentration of CT was determined by detecting the change of capacitance caused by the formation of antibody-antig

Background: In soils contaminated by hydrophobic organic compounds, the concentrations are less indicative of potential exposure and distribution than are the associated chemical activities, fugacities and freely dissolved concentrations. The latter can be measured by diffusive sampling into thin layers of polymer, as in, for example, solid phase micro-extraction. Such measurements require equilib

Popular Abstract in Undetermined Populärvetenskaplig sammanfattning på svenska Nästäppa, som betyder svårigheter att andas med näsan är ett vanligt symtom i befolkningen, och en vanlig orsak till att patienter söker vård. Kronisk nästäppa är ett frekvent symtom (ca 40 % av vuxna) som ofta medför mun-andning med torra slemhinnor i munhåla och svalg samt snarkning till följd. Nässkiljeväggen, septSubjective nasal obstruction is a common chronic complaint caused by mucosal disease, skeletal abnormality or a combination of both. The challenge is to determine the main cause and to decide whether the intervention should be medical or surgical. Diagnosis is done by a combination of rhinoscopy, subjective and objective assessments of nasal obstruction. Rhinomanometry measures the nasal airway re

This article should serve as an introduction to a relatively new topic in ethnological studies requiring very specific methods as it involves both offline and online research as well as material objects and immaterial practices. How do we embark on an interdisciplinary venture such as this, and be sure to produce qualitative research of high standard? How should gaming mothers best be studied? In

Neuromodulators, such as serotonin (5-hydroxytryptamine, 5-HT) and noradrenalin, play an essential role in regulating the motor and sensory functions in the spinal cord. We have previously shown that in the rat spinal cord the activity of aromatic L-amino acid decarboxylase (AADC) cells to produce 5-HT from its precursor (5-hydroxytryptophan, 5-HTP) is dramatically increased following complete spi

The unique opportunity to study and control electron-nuclear quantum dynamics in coupled potentials offered by the resonant inelastic X-ray scattering (RIXS) technique is utilized to unravel an anomalously strong two-electron one-photon transition from core-excited to Rydberg final states in the CO molecule. High-resolution RIXS measurements of CO in the energy region of 12-14 eV are presented and

Banks (but not stock markets) promote economic growth by facilitating relationship-specific investment between buyers and suppliers of intermediate goods. Combined insights from literature on signaling role of banks and on relationship-specific investment motivate this economic channel: A supplier is reluctant to undertake relationship-specific investment as she cannot observe financial stability

Aqueous potassium chloride has been studied by synchrotron-radiation excited core-level photoelectron and Auger electron spectroscopy. In the Auger spectrum of the potassium ion, the main feature comprises the final states where two outer valence holes are localized on potassium. This spectrum exhibits also another feature at a higher kinetic energy which is related to final states where outer val

In the field of infectious diseases the multifaceted amino acid arginine has reached special attention as substrate for the hosts production of the antimicrobial agent nitric oxide (NO). A variety of infectious organisms interfere with this part of the host immune response by reducing the availability of arginine. This prompted us to further investigate additional roles of arginine during pathogen
