The hazards of kissing when you are food allergic - A survey on the occurrence of kiss-induced allergic reactions among 1139 patients with self-reported food hypersensitivity
Background: According to a few case reports, kissing can induce symptoms due to food allergy. Objective: We wanted to investigate the occurrence of kiss-induced allergic symptoms and other social inconveniences among patients with self-reported food hypersensitivity. Methods: A questionnaire was answered by 1139 patients (1-84 years old, mean age 29 years, 393 males and 746 females) who considered
Structure of native protein C inhibitor provides insight into its multiple functions
Protein C inhibitor (PCI) is a multifunctional serpin with wide ranging protease inhibitory functions, unique cofactor binding activities, and potential non-inhibitory functions akin to the hormone-transporting serpins. To gain insight into the molecular mechanisms utilized by PCI we developed a robust expression system in Escherichia coli and solved the crystal structure of PCI in its native stat
Elevated plasma levels of soluble CD40 in incipient Alzheimer's disease.
CD40 is a member of the tumor necrosis factor receptor super-family and has been suggested to play a role in the metabolism of beta-amyloid (Abeta) in Alzheimer's disease (AD). However, the role of CD40-signalling in incipient AD has not yet been studied. We investigated the plasma levels of soluble CD40 (sCD40) and the soluble CD40 ligand (sCD40L) at baseline in 136 subjects with mild cognitive i
Avian reservoirs and zoonotic potential of the emerging human pathogen Helicobacter canadensis
A polyphasic identification approach was used to investigate the taxonomic position of Campylobacter-like isolates recovered from barnacle geese (Branta leucopsis) and Canada geese (Branta candensis). Seven strains were selected from a collection of 21 isolates and analyzed by extensive phenotypic testing; four strains were characterized by 16S rRNA gene sequence analysis. The results clearly iden
Seeking Asylum and Residence Permits in Sweden : Denial, Acknowledgement, and Bureaucratic Legitimacy
Sweden's reputation as one of the most encompassing welfare states in the world is maintained by means of a good self-image, not least in relation to refugee policies. At the same time, external authorities have been critical of Sweden's handling of the process of seeking asylum. Drawing on Stanley Cohen's concepts of denial and partial acknowledgment, the article explores how Swedish state offici
pp→ppη′ reaction at high energies
We discuss double-diffractive (double-elastic) production of the η′-meson in the pp→pη′p reaction within the formalism of unintegrated gluon distribution functions (UGDF). We estimate also the contribution of γ*γ*→η′ fusion. The distributions in the Feynman xF (or rapidity), transferred four-momenta squared between initial and final protons (t1,t2) and azimuthal angle difference between outgoing p
Dispersive approach to the axial anomaly and nonrenormalization theorem
Anomalous triangle graphs for the divergence of the axial-vector current are studied using the dispersive approach generalized for the case of higher orders of perturbation theory. The validity of this procedure is proved up to the two-loop level. By direct calculation in the framework of dispersive approach we have obtained that the two-loop axial-vector-vector (AVV) amplitude is equal to zero. A

Metabolic fate of C-14-labelled chlorinated and non-chlorinated fatty acids in goldfish (Carassius auratus)
In order to study the metabolic fate of chlorinated fatty acids in fish, goldfish were fed either 9,10-dichlorostearic acid or oleic acid, chosen as the unchlorinated analogue, both radiolabelled at either the carboxyl (1st) or the terminal (18th) carbon of the fatty acid chain. By keeping the fish in hermetically closed aquaria, all the respired, assimilated and excreted radioactivity could be ac
Spectroscopic characterization of intermediate steps involved in donor-side-induced photoinhibition of photosystem II
The reaction center protein D1 in photosystem II shows a high turnover during illumination. The degradation of the DI protein is preceded by photoinhibition of the electron transport in photosystem II. There are two distinct mechanisms for this: acceptor-side- and donor-side-induced photoinhibition. Here, donor-side-induced photoinhibition was studied in photosystem II membranes after Cl- depletio
3,7-dideacetyl-6 alpha-hydroxykhivorin, a new limonoid from Khaya senegalensis (Meliaceae)
A new limonoid, 3,7-dideacetyl-6 alpha-hydroxykhivorin, together with khivorin, 3-deacetylkhivorin, 7-deacetoxy-3-deacetyi-7-oxokhivorin, and 6-deoxydestigloylswietenine acetate have been isolated from,the seeds of Khaya senegatensis. Their structures were established by analysis of the high-field NMR and MS data.
Polynomial-time algorithms for the ordered maximum agreement subtree problem
For a set of rooted, unordered, distinctly leaf-labeled trees, the NP-hard maximum agreement subtree problem (MAST) asks for a tree contained (up to isomorphism. or homeomorphism) in all of the input trees with as many labeled leaves as possible. We study the ordered variants of MAST where the trees are uniformly or non-uniformly ordered. We provide the first known polynomial-time algorithms for t
ACC/AHA/ESC 2006 guidelines for the management of patients with atrial fibrillation--executive summary: a report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines and the European Society of Cardiology Committee for Practice Guidelines (Writing Committee to Revise the 2001 Guidelines for the Management of Patients With Atrial Fibrillation)
Transport properties of three-terminal ballistic junctions realized by focused ion beam enhanced etching in InGaAs/InP
Three-terminal junction devices are realized in an InGaAs/InP quantum well by focused ion beam (FIB) implantation and selective wet etching. Room temperature electrical measurements show that the fabricated devices exhibit strong nonlinear electrical properties. The results are discussed in terms of ballistic electron transport. It is demonstrated that FIB-enhanced etching processing can be exploi
Volume flow calculations on gas leaks imaged with infrared gas-correlation
Two methods for volume flow calculation from images of methane leakages to the atmosphere are presented. The images contain calibrated gas concentration x path length pixel information, and are processed with a block matching method and a theoretical velocity field method. Results from known methane flow in two laboratory setups and one unknown real leakage from a gas processing plant are compared

How Might Novel Technologies Such as Optogenetics Lead to Better Treatments in Epilepsy?
Recent technological advances open exciting avenues for improving the understanding of mechanisms in a broad range of epilepsies. This chapter focuses on the development of optogenetics and on-demand technologies for the study of epilepsy and the control of seizures. Optogenetics is a technique which, through cell-type selective expression of light-sensitive proteins called opsins, allows temporal
