Inter-firm job switching of workers is a much cited but seldom measured source of the productivity advantages of spatial employment density. It has been advanced as a conduit for localized knowledge flows as well as labor market matching efficiency. Using a matched employer-employee dataset for Sweden, we estimate the influence spatial employment density has on the probability of inter-firm job sw

This study evaluated the effects of retinal ischemia-reperfusion (IR) injury and pre-treatment with the potent and specific aldose reductase inhibitor fidarestat on apoptosis, aldose reductase and sorbitol dehydrogenase expression, sorbitol pathway intermediate concentrations, and oxidative-nitrosative stress. Female Wistar rats were pre-treated with either vehicle (N-methyl-D-elucamine) or fidare

Based on atomic force microscopy nanoindentation measurements of phage λ, we previously proposed a minimal model describing the effect of water hydrating DNA that strengthens viral capsids against external deformation at wild-type DNA packing density. Here, we report proof of this model by testing the prediction that DNA hydration forces can be dramatically decreased by addition of multivalent ion

Telomere length has been associated with risk of many cancers, but results are inconsistent. Seven single nucleotide polymorphisms (SNPs) previously associated with mean leukocyte telomere length were either genotyped or well-imputed in 11 108 case patients and 13 933 control patients from Europe, Israel, the United States and Australia, four of the seven SNPs reached a P value under .05 (two-side

We demonstrate radio frequency single-electron transistors fabricated from epitaxially grown InAs/InP heterostructure nanowires. Two sets of double-barrier wires with different barrier thicknesses were grown. The wires were suspended 15 nm above a metal gate electrode. Electrical measurements on a high-resistance nanowire showed regularly spaced Coulomb oscillations at a gate voltage from -0.5 to

Popular Abstract in Swedish Livmoderhalscancer är den näst vanligaste cancerformen att drabba kvinnor. Behandlingen baseras på vilket stadium sjukdomen befinner sig i och innebär en avsevärd risk för biverkningar. FDG-PET är en undersökningsmetod som kan visualisera områden i kroppen med ökat sockerupptag. Cancerceller har en kraftigt ökad omsättning av socker och därmed kan tumörer avbildas med FCervical cancer is the second most common cancer in females. The treatment, based on clinical FIGO stage, carries a significant risk of side effects. FDG-PET enables non-invasive studies of glucose metabolism. Cancer cells show an increased glucose uptake and metabolism that can be visualised and further analysed. The aims of this thesis were to evaluate FDG-PET in the clinical management of cerv

Popular Abstract in Swedish Invasiv candidiasis är en allvarlig jästsvampinfektion hos redan svårt sjuka patienter och denna infektion har ökat under de senaste årtiondena. Blododling, som ärreferensdiagnostisk metod för denna infektion, har relativt låg känslighet liksom detektion av Candidaspecifika antikroppar och antigener. Utvecklingen av PCR baserade diagnostik går långsamt och det saknas stInvasive candidiasis (IC) is a serious condition and timely diagnosis with early initiation of antifungal therapy is imerative for improving outcomes. Arabinitol is a sugar alcohol with two stereoisomers, D-arabinitol (DA) and L-arabintiol (LA). Several pathogenic Candida species produce DA in vitro and high DA levels have been detected in serum and urine in patients with IC. Renal dysfunction aff

Flower colour is an important signal used by flowering plants to attract pollinators. Many anthophilous insects have an innate colour preference that is displayed during their first foraging bouts and which could help them locate their first nectar reward. Nevertheless, learning capabilities allow insects to switch their colour preferences with experience and thus, to track variation in floral nec

Temperature-corrected oxygen measurements were performed by using multi-mode diode laser correlation spectroscopy at temperatures ranging between 300 and 473 K. The experiments simulate in situ monitoring of oxygen in coal-combustion exhaust gases at the tail of the flue. A linear relationship with a correlation coefficient of -0.999 was found between the evaluated concentration and the gas temper

Hydroquinone glycosides were produced by transglycosylation reactions catalyzed by cyclodextrin glucanotransferase (CGTase) from Thermoanaerobacter sp. (Toruzyme (R) 3.0L). The reactions were carried out in an aqueous system containing hydroquinone (HQ) and maltodextrin as acceptor and donor substrate molecules respectively. The conditions for the synthesis of hydroquinone glucoside (alpha-arbutin

We investigated the brain-tissue response to nanowire implantations in the rat striatum after 1, 6, and 12 weeks using immunohistochemistry. The nanowires could be visualized in the scar by confocal microscopy (through the scattered laser light). For the nanowire-implanted animals, there is a significant astrocyte response at week 1 compared to controls. The nanowires are phagocytized by ED1 posit

Background: Although both labour dystocia and domestic violence during pregnancy are associated with adverse maternal and fetal outcome, evidence in support of a possible association between experiences of domestic violence and labour dystocia is sparse. The aim of this study was to investigate whether self-reported history of violence or experienced violence during pregnancy is associated with in

Single photons detected by the DELPHI experiment at LEP2 in the years 1997-2000 are reanalysed to investigate the existence of a single extra dimension in a modified ADD scenario with slightly warped large extra dimensions. The data collected at centre-of-mass energies between 180 and 209 GeV for an integrated luminosity of similar to 650 pb(-1) agree with the predictions of the Standard Model and

Background: Prostate cancer is a leading cause of death in the male population of the western world. Human kallikrein-related peptidase 2 (hK2) is abundantly expressed in malignant prostatic tissue, and its gene, KLK2, is regulated by the androgen receptor. 11B6 is a murine IgG(1) monoclonal antibody directed against free human hK2. In this study, we performed a preclinical evaluation of In-111-la

Using the ImmunoChip custom genotyping array, we analyzed 14,498 subjects with multiple sclerosis and 24,091 healthy controls for 161,311 autosomal variants and identified 135 potentially associated regions (P < 1.0 x 10(-4)). In a replication phase, we combined these data with previous genome-wide association study (GWAS) data from an independent 14,802 subjects with multiple sclerosis and 26,703

We study the effects of a phase difference on Yu-Shiba-Rusinov (YSR) states in a spinful Coulomb-blockaded quantum dot contacted by a superconducting loop. In the limit where charging energy is larger than the superconducting gap, we determine the subgap excitation spectrum, the corresponding supercurrent, and the differential conductance as measured by a normal-metal tunnel probe. In absence of a
