One-dimensional semiconductor nanowires are a promising candidate for future electronic devices. The epitaxial growth of nanowires is often mediated by metal seed particles, usually gold particles. In this paper the setup of a simple and robust technique to generate nanometer-sized aerosol gold particles by spark discharge is described. Furthermore we demonstrate for the first time that particles

Conclusions. Intranasal microemulsion treatment can attenuate allergen challenge-induced nasal symptoms and plasma exudation in allergic rhinitis. We hypothesize that the mechanism of action involves modification of the allergen-mucosa interaction. The present observation suggests a novel principle for prevention in allergic rhinitis. Objective. To evaluate a specific microemulsion as a treatment

Epidemiologic studies have shown conflicting results regarding the role of traffic pollution in the development of allergic disease. This study investigated the relationship between living close to traffic and ever dispense of prescribed oral antihistamines or nasal anti-allergic medication, among young children. The underlying aim was to investigate if children growing up close to traffic polluti

Aim Increased concentration of nitric oxide (NO) metabolites, nitrite and nitrate, in the urine is a strong indication of ongoing small intestinal, inflammation, which is a hallmark of the enteropathy of celiac disease (CD). It has previously been shown that children with symptomatic, untreated CD have increased levels of NO oxidation products in their urine. The aim of the present study was to in

This chapter is an overview of the prehistory of L, how people across the globe from our earliest sources to 1961 have tried to understand the beginning and end of history, and the rise and fall of civilizations. Factor L is put into a longer historical context of human conceptions about history, time, and civilization. In focus is the question of how it was possible to formulate L in its modern v

Popular Abstract in Swedish Bröstcancer är den vanligaste cancerdiagnosen hos svenska kvinnor, ca 8000 tumörer diagnosticeras årligen. Vid rekommendation om behandling till patienter med nyupptäckt bröstcancer utgår man från ett antal prognostiska (risk för återfall och död utan behandling) och prediktiva (risk för återfall och död med specifik behandling) faktorer. Ålder, tumörstorlek, cancercellBreast cancer is a heterogeneous disease with variations in the biological profile and subsequent clinical prognosis. Molecular mechanisms for tumour progression are currently being explored in scientific settings, suggesting parallel evolution of tumour cells at primary and metastatic locations. The molecular profiles could be altered affecting individual patient’s treatment and prognosis. In the

Forest soil carbon (C) pools may act as sinks for, or sources of, atmospheric carbon dioxide, while nitrogen (N) fertilization may affect the net exchange of C in forest ecosystems. Since all major C and N processes in soil are driven by soil microorganisms, we evaluated the effects of N fertilization on biomass and bacterial and fungal activity in soils from three Norway spruce forests with diffe

Low temperature is one of the major environmental factors that adversely affect plant growth and yield. Many cereal crops from tropical regions, such as rice, are chilling sensitive and, therefore, are affected already at

Large plants are often more conspicuous and more attractive for associated animals than small plants, e.g. due to their wider range of resources. Therefore, plant size can positively affect species richness of associated animals, as shown for single groups of herbivores, but studies usually consider intraspecific size differences of plants in unstandardised environments. As comprehensive tests of

Recent genome-wide association studies reported that GCKR rs780094 polymorphism is associated with elevated fasting serum triglyceride levels and elevated levels of C-reactive protein (CRP). There are a ample of data on the association between circulating triglyceride, CRP concentrations and risk of non-alcoholic fatty liver (NAFLD). To determine whether the GCKR rs780094 polymorphism contributes

Congenital or acquired hearing loss is often associated with a progressive degeneration of the auditory nerve (AN) in the inner ear. The AN is composed of processes and axons of the bipolar spiral ganglion neurons (SGN), forming the connection between the hair cells in the inner ear cochlea and the cochlear nuclei (CN) in the brainstem (BS). Therefore, replacement of SGNs for restoring the AN to i

Absorption and fluorescence spectral properties of J-aggregates of core-tetrasubstituted perylene bisimide (PBI) dyes have been investigated in the temperature range from 300 to 5 K. A special feature of the present PBI J-aggregates is that, in contrast to classical J-aggregates like that of pseudoisocyanine (PIC), the chromophores are held together not only by van-der-Waals interactions but also

NPM bör inte användas som ett enkelt penseldrag med ambitionen att förklara komplexa problem, vinna gillande och locka folk till barrikaderna. Den här artikeln visar på ett antal risker som finns med dagens användning av begreppet i såväl populärdebatt som forskningsdebatt. Framför allt riskerar det att leda till en onödig polarisering och kraftiga förenklingar av komplexa problem.

We study the complexity of detecting monomials with special properties in the sum-product expansion of a polynomial represented by an arithmetic circuit of size polynomial in the number of input variables and using only multiplication and addition. We focus on monomial properties expressed in terms of the number of distinct variables occurring in a monomial. Our first result is a randomized FPT al

Recombinant human erythropoietins (rHuEPOs) are used to treat cancer-related anemia. Recent preclinical studies and clinical trials, however, have raised concerns about the potential tumor-promoting effects of these drugs. Because the clinical significance of erythropoietin receptor (EPOR) signaling in human non-small cell lung cancer (NSCLC) also remains controversial, our aim was to study whethe

For enhancing anaerobic membrane bioreactor (AnMBR) treating food processing wastewater due to speed-limited methanogenesis step, multiple effects of trace element (TE) supplementation on methanogenesis of a two-phase AnMBR were firstly investigated in batch tests. TE supplementation included individual element, combination and recovery of Fe, Ni, Co, Cu and Zn supplementation. Multiple effects of
