BACKGROUND: Anisakis simplex, a fish parasite, causes allergic urticaria, angioedema and anaphylactic shock through an IgE-mediated hypersensitivity mechanism. Consensus on the dietary recommendations that should be given to allergic patients is lacking. Our objective was to evaluate the usefulness of different types of diets in preventing further reactions in patients allergic to A. simplex. METH
The efficiency of different preparations of lipases was evaluated in organic solvents. Lipases from Humicola lanuginosa, Candida rugosa, Rhizomucor miehei and Pseudomonas cepacia were adsorbed onto the surfactant sorbitan monostearate (Span 60) and the specific activities were compared in hexane to crude powder (used straight from the bottle) and lipase freeze-dried from buffer solution. Lipases a
The previous supersymmetric generalization of the unitary Harish-Chandra integral prompted the conjecture that the Harish-Chandra formula should have an extension to superspaces. We prove this conjecture for the unitary orthosymplectic supermanifold UOSp(k(1)/2k(2)). To this end, we construct and solve an eigenvalue equation.
Given a set V of n points in R-d and a real constant t > 1, we present the first O(n log n)-time algorithm to compute a geometric t-spanner on V. A geometric t-spanner on V is a connected graph G = ( V, E) with edge weights equal to the Euclidean distances between the endpoints, and with the property that, for all u, v is an element of V the distance between u and v in G is at most t times the Euc
We propose a novel method for completely characterizing ultrashort pulses at extreme-ultraviolet (XUV) wavelengths by adapting the technique of spectral phase interferometry for direct electric-field reconstruction to this spectral region. Two-electron wave packets are coherently produced by photoionizing atoms with two time-delayed replicas of the XUV pulse. For one of the XUV pulses, photoioniza
Background: Optimal therapeutic management of intravascular lymphoma (IVL) lacks precise guidelines. Patients and methods: The clinico-pathological features of 38 HIV-negative patients with IVL were reviewed to define efficacy of chemotherapy in these malignancies. Clinical characteristics of 22 patients treated with chemotherapy and of 16 untreated patients were compared in order to understand be
Popular Abstract in Swedish Ur ett evolutionärt perspektiv har förmågan att lagra energi varit fördelaktig när tillgången på föda varit begränsad. I våra dagar i västvärlden råder det ingen brist på mat och vår förmåga att lagra energi har istället blivit en börda i dubbel bemärkelse. Energi lagras i kroppen framförallt i form av fett, s.k. triglycerider. Övervikt och fetma kan idag sägas utgöra eHormone-sensitive lipase (HSL) has a wide tissue distribution with the highest expression found in white adipose tissue (WAT). HSL also has a unique ability to hydrolyze a large panel of substrates including acylglycerols, cholesteryl esters and retinyl esters. HSL is potentially a new drug target for the treatment of obesity and type II diabetes. However, as HSL is not only expressed in adipose t
A detector system for positron emission tomography with time-of-flight capability has been built to serve as an educational tool for undergraduate students. The set-up consists of 48 BaF2 scintillator crystals, each coupled to a fast photo-multiplier tube, mounted in a circular geometry. The analogue detector pulses are handled by fast constant fraction discriminators. A dedicated unit reduces the
This report is part of a project that is called Generic hybrid systems. Its objective is to simulate and investigate electric hybrid drive trains. The goal of this work has been to develop combustion engine models that are computer efficient, but still has the potential of giving both qualitative and quantitative results. For instance, if the model is run in a less ideal manner the model will show
Operation of homogeneous charge compression ignition (HCCI) enginesare very sensitive to timing variations in the combustion of theair-fuel charge mixture and require precise control of the ignitioninstant to run properly. It is therefore essential to understand thecharacteristics of timing variations under various operatingconditions in order to find suitable control strategies. This paperpresent
We describe a fast and accurate collision-detection algorithm specialised for models deformed by morphing. The models considered are meshes where the vertex positions are convex combinations of sets of reference meshes. This new method is based on bounding-volume trees that are extended to support efficient tree-node updates by blending associated sets of reference bounding volumes. With our appro
This report describes a language and an interactive environment, called LICS, for implementation of control systems and dynamic modelling. It used graphics for representation of the structural properties: hierarchical decomposition, interconnection structure, and structure of the interfaces. The decomposition and interconnection structures are described by block diagrams. Low level modules are des
In order to induce local hyperthermia in superficial tumours a computer system using a 2,450 MHz microwave generator connected to a circular (diameter 90 mm) direct contact applicator was constructed based on invasive temperature control. Small thermistor probes with a diameter of 0.6 mm are inserted in the tumour and surrounding tissues. Eight thermistors can be used simultaneously and one of the
Utförlig beskrivning av hårdvara för datoriserad styrning och övervakning av installationer. Rapporten är av beskrivande karaktär främst för att det är svårt att jämföra olika fabrikats lösningar av samma funktion. Komplettering av R114:1980 med programvara
In this paper, we present the development of a remote server that provides a user-friendly access to advanced electrocardiographic (ECG) signal processing techniques. The prototype supplies telemedicine facilities to doctors for clinical indexes remote computation to support diagnosis through the Internet. The user-friendly interface is based on the selection of the desired ECG signal processing t
A group of Swedish radiation oncologists and hospital physicists have estimated the number of patients in Sweden suitable for proton beam therapy in a facility where one of the principal aims is to facilitate randomized and other studies in which the advantage of protons can be shown and the magnitude of the differences compared with optimally administered conventional radiation treatment, also in
