Background: Neurogenic inflammation has for decades been considered an important part of migraine pathophysiology. In the present study, we asked the question if administration of a novel kynurenic acid analogue (SZR72), precursor of an excitotoxin antagonist and anti-inflammatory substance, can modify the neurogenic inflammatory response in the trigeminal ganglion. Methods: Inflammation in the tr

The extent and type of nutrient limitation will affect soil microorganism activity and may change the balance between organism groups, like fungi and bacteria. Limiting nutrients have traditionally been measured as increased respiration after adding nutrients, but this will not differentiate between fungal or bacterial responses. We compared respiration, bacterial and fungal growth after alleviati

Fusobacterium necrophorum is a gram-negative anaerobic bacterium that is the causative agent of the invasive disease Lemierre's syndrome. In addition, it is also associated with peritonsillar abscess formation and otitis media in small children. Recent research has shown that F. necrophorum may be involved in pharyngotonsillitis especially in adolescent and young adults and that it may be the seco

This report presents the general lessons learned from the investigated 24 case studies from 10 countries.

For drug delivery, characterization of liposomes regarding size, particle number concentrations, occurrence of low-sized liposome artefacts and drug encapsulation are of importance to understand their pharmacodynamic properties. In our study, we aimed to demonstrate the applicability of nano Electrospray Gas-Phase Electrophoretic Mobility Molecular Analyser (nES GEMMA) as a suitable technique for

Our knowledge of sports-related injuries in para-sport is limited and there are no data on how Paralympic athletes themselves perceive an injury. The aim of this qualitative study was to explore Paralympic athletes’ perceptions of their experiences of sports-related injuries, risk factors and preventive possibilities. Eighteen Swedish Paralympic athletes with vision impairment, intellectual impair

Using synchronized rapid video imaging and calibrated acoustic emission (AE) measurements, a direct correspondence is found between the length of emerging twin and its AE transient response during in-situ testing of Mg polycrystals. The detectability limit for twin nucleation in Mg and its alloys is evaluated to be as small as 0.3 µm or even less. It is shown that the use of appropriate calibratio

Non-contact surface wave measurements are performed on a new asphalt concrete (AC) pavement using 48 micro-electro-mechanical system (MEMS) sensors as receivers to estimate the real part of the dynamic moduli of the AC top layer. Laboratory measurements of core samples, extracted from the field measurement positions, are used to construct master curves for comparison with the field measurements. T

In the present work, multifunctional Ti-Si-N coatings have been deposited using CAVD method with the aim of studying their chemical, physical, structural and mechanical properties. Coatings of Ti-Si-N were modified by high-intensity ion implantation using copper ions with dose D = 2 × 1017 ions/cm2 and energy E = 60 keV. The results demonstrated that ion implantation has an effect on the grain siz

According to the Innovation Union Scoreboard published by the EuropeanCommission, Sweden has been, and still is, an innovation leader within the EU and one of the most innovative countries in Europe. In this paper, the performance of the Swedish national innovation system is analyzed using exactly the same data as those employed by the Innovation Union Scoreboard for the years 2014 and 2015.We arg

The persistence length of cationic dendronized polymers adsorbed onto oppositely charged substrates was studied by atomic force microscopy (AFM) and quantitative image analysis. One can find that a decrease in the ionic strength leads to an increase of the persistence length, but the nature of the substrate and of the generation of the side dendrons influence the persistence length substantially.

In this paper, we provide a formalism for the characterization of tracking arrays with emphasis on the proper corrections required to extract their photopeak efficiencies and peak-to-total ratios. The methods are first applied to Gammasphere, a well characterized 4π array based on the principle of Compton suppression, and subsequently to GRETINA. The tracking efficiencies are then discussed and so

Hydrophobic resin acids (RAs) are synthesized by conifer trees as part of their defense mechanisms. One of the functions of RAs in plant defense is suggested to be the perturbation of the cellular membrane. However, there is a vast diversity of chemical structures within this class of molecules, and there are no clear correlations to the molecular mechanisms behind the RA's toxicity. In this study

Fiber composites are widely used for space applications such as antennas, solar panels and spacecraft support structures. This paper presents a combined electromagnetic and acoustic analysis of a triaxial carbon fiber weave structure, designed for ultra lightweight reflector antennas in satellite communication systems. The electromagnetic and acoustic performance of the structure are analyzed over

The mechanism of ethylene polymerization on phenoxy-imine (FI) titanium catalysts was studied theoretically to identify the major factors affecting the catalytic activity. Geometry optimizations of FI ligands, octahedral titanium dichloride complexes, active cationic species, and their π‐complexes with ethylene as well as calculations of the energy profile of chain propagation were performed at th
