We image the field enhancement at Ag nanostructures using femtosecond laser pulses with a center wavelength of 1.55 mu m. Imaging is based on non-linear photoemission observed in a photoemission electron microscope (PEEM). The images are directly compared to ultra violet PEEM and scanning electron microscopy (SEM) imaging of the same structures. Further, we have carried out atomic scale scanning t

The present work describes the development of a novel direct screening method, assayed in 96-well format, for evaluation of enzymatic alkyl glycoside production in a hexanol water two-phase system. Alkyl glycosides are surfactants with a range of applications and with good biodegradability and low toxicity. Enzymatic synthesis makes it possible to prepare beta-D-glucopyranosides with high purity.

Response to targeted therapies varies significantly despite shared oncogenic mutations. Nowhere is this more apparent than in BRAF(V600E)-mutated melanomas where initial drug response can be striking and yet relapse is commonplace. Resistance to BRAF inhibitors have been attributed to the activation of various receptor tyrosine kinases (RTKs) though the underlying mechanisms have been largely unch

We identified the first set of microsatellites for use in the rock firefinch (Lagonosticta sanguinodorsalis). First, we tested existing passerine microsatellite loci for cross-species amplification success in a small sample of rock firefinches and identified 10 loci that were seemingly polymorphic and easy to score. Secondly, we developed and characterized three microsatellite loci de novo from th

CONTEXT: The psychosocial health and working capacity in hypopituitary patients receiving long-term growth hormone (GH) therapy are unknown. OBJECTIVE: Psychosocial health and levels of employment were compared between GH deficient (GHD) patients on long-term replacement and the general population. DESIGN AND PARTICIPANTS: In a Swedish nationwide study, 851 GHD patients [101 childhood onset (CO) a

In this study we investigated whether single nucleotide polymorphisms (SNP) in the genes coding for BDNF (Val66Met) and VEGF (C2578A) may be associated with maladaptive strategies among suicide attempt patients. We found that BDNF Val66Met gene polymorphism probably affect avoidant coping strategies.

During GH therapy for 2.3-9.6 years a male adult onset (AO) GH deficient (GHD) patient with a diagnosis of a non-functioning adenoma, have no increased all-cause mortality. However, women with AO GHD are still at a slightly higher risk. This general improvement in mortality is due to; more contemporary regiment of cardiovascular drugs, a refinement of surgical procedures, besides GH therapy improv

Mobile communication systems are becoming increasingly heterogeneous as new standards emerge. Currently, the wireless operators are upgrading their existing 3G networks such as UMTS and CDMA2000 to different kinds of 4G networks such as LTE and WiMAX. We can witness these days that mobile terminals are having the capability to access many of these wireless network types. The networks are very diff

Five adult volunteers participated in a biokinetic study of radioactive polonium. Portions of about 10Bq of (209)Po were orally administrated to four of the volunteers in a single ingestion. The fifth volunteer ingested a daily amount of 53mBq of 209Po for 243d to study the time to achieve equilibrium between intake and excretion for protracted intakes. For the subjects ingesting single intakes of

To investigate the role of P2Y1 and P2Y12 receptors in hypoxia- and adenosine diphosphate (ADP)-induced pulmonary vasoconstriction.

A measurement of the ZZ production cross section in proton-proton collisions at root s = 7 TeV using data corresponding to an integrated luminosity of 1.02 fb(-1) recorded by the ATLAS experiment at the LHC is presented. Twelve events containing two Z boson candidates decaying to electrons and/or muons are observed, with an expected background of 0.3 +/- 0.3(stat)(-0.3)(+0.4)(syst) events. The cro

The d-orbital contribution from the transition metal centers of phthalocyanine brings difficulties to understand the role of the organic ligands and their molecular frontier orbitals when it adsorbs on oxide surfaces. Here we use zinc phthalocyanine (ZnPc)/TiO2(110) as a model system where the zinc d-orbitals are located deep below the organic orbitals leaving room for a detailed study of the inte

Protein S-nitrosylation plays important role in the regulation of cardiovascular functions in nitric oxide (NO) Pathway. Hypercysteinemia (HHcy) is an independently risk factor for atherosclerosis. We hypothesized that HHcy promotes atherosclerosis by reducing level of vascular protein S-nitrosylation. The aim of present study is to investigate effect of HHcy on vascular protein S-nitrosylation. A

In this paper, the freeze-thaw stability of mayonnaise type oil-in-water emulsions is studied. The emphasis of the experiments have been on the properties of the dispersed oil phase as only small, or no effects, were observed from initial experiments on changing the properties of the aqueous phase within the investigated ranges. Different vegetable oils are investigated in order to relate the comp

OBJECTIVES: The aim of the present study was to examine the prevalence and associated factors of dietary supplement use, particularly supplements containing vitamin D and fatty acids, in pregnant women enrolled in a multi-national study. DESIGN: The Environmental Determinants of Diabetes in the Young (TEDDY) study is a prospective longitudinal cohort study. Maternal dietary supplement use was self

Background. In formal experiments on software engineering, the number of factors that may impact an outcome is very high. Some factors are controlled and change by design, while others are are either unforeseen or due to chance. Aims. This paper aims to explore how context factors change in a series of for- mal experiments and to identify implications for experimentation and replication practices

In the light of the critique that intersectionality demands and reproduces static identity categories, the editors of Theorising intersectionality and sexuality, Yvette Taylor, Sally Hines and Mark E. Casey, and with them the authors of the 12 texts in the book, assert the usefulness of ‘claims making, entitlements and “rights” of situated sexual citizens’ (3), if it is connected to empirical work

Background: The prospective, multinational European 'Stroke in Young Fabry Patients' (sifap1) study collected 4,467 patients with acute ischemic cerebrovascular events aged 18-55 years. Initially, aetiologic subtyping was performed using the TOAST classification; however, recently the phenotypic ASCO classification was presented and might be more useful to identify stroke aetiologies in young pati
