SoPIP2;1 is one of the major integral proteins in spinach leaf plasma membranes. In the Xenopus oocyte expression system its water channel activity is regulated by phosphorylation at the C terminus and in the first cytosolic loop. To assess its structure, SoPIP2;1 was heterologously expressed in Pichia pastoris as a His-tagged protein and in the non-tagged form. Both forms were reconstituted into

Energy correlations between gamma -ray transitions and the prompt proton decay line in Cu-58 were studied by means of the fusion-evaporation reaction Ca-40(Mg-24,1 alpha 1p1n) using the EUROBALL spectrometer coupled to ancillary detector devices. A lifetime of 0.06 < tau < 0.58 ps for the 8915 keV proton-decaying state in Cu-58 is deduced. (C) 2001 Elsevier Science B.V. All rights reserved.

A consecutive series of patients with all types of cervical hip fracture (both undisplaced and displaced) were randomised to osteosynthesis with Hansson hook-pins (n = 98) or AO-screws (n = 101). Background parameters, fracture type and reduction of the fracture did not differ significantly between the groups. Fifty-seven percent of the patients were operated on within 6 h of admission to hospital

In recent years, small bogs at Hassleberga in southwestern Scania have been turned into crayfish ponds after the removal of the organic sediments. Bones and antlers were noticed in the excavated material and have been systematically collected. The finds include reindeer of both sexes and of different ages. Bones of wild horse, elk, arctic hare and arctic fox were also identified. Radiometric datin

Har litteraturen makt att påverka människan och samhällsutvecklingen? Är det verkligen så att litteraturen har hjälpt till att avskaffa slaveriet i Amerikas sydstater eller att ge svenskarna religiös mötesfrihet? Kan den ha skadat äktenskapet som institution eller gett avgörande synpunkter inom barnuppfostran? Har den inspirerat FN i miljöfrågor, gett svenskarna dräpande argument i kärnkraftsdebat

Reaction of [Rh6(CO)15(NCMe)] with p-thiocresol [(4-Me)C6H4SH] leads to the formation of [Rh2(CO)4(μ-SC6H4CH3)2] as the main product along with a small amount of [Rh6(CO)16]. An approximately 30-fold excess of the thiol is required in order to obtain a good yield of the thiolate-bridged dimer while reaction of [Rh4(CO)12] with an excess of p-thiocresol leads to an apparently clean conversion to th

OBJECTIVES: Antibodies against herpes simplex viruses-1 and -2, cytomegalovirus, and syphilis were determined in six heterosexual couples with strong indications of having sexually transmitted hepatitis C virus infection and in 17 other heterosexual couples in which one partner was hepatitis C virus viremic (source partner), but the other had remained hepatitis C virus uninfected (exposed partner)

Energy metabolism at the level of any particular tissue is tightly regulated by hormones, neurotransmitters and cytokines in order to maintain overall energy homeostasis. Any dysfunctions in energy metabolism may lead to more or less severe consequences, with obesity and type 2 diabetes being the most prevalent ones. Type 2 diabetes is characterized by defective insulin secretion (?-cell dysfuncti

Lung scintigraphy is the primary tool for diagnostics of pulmonary embolism. A perfusion study is often complemented by a ventilation study. Intermediate probability scans are frequent. Our goal was to develop a fast method for tomographic ventilation and perfusion scintigraphy to improve the diagnostic value of lung scintigraphy. METHODS: SPECT was performed with a dual-head gamma camera. Acquisi

We present accurate calculations of oscillator strengths and hyperfine structure splitting for a set of transitions in Tl II, and discuss how they can be used in stellar atmosphere models of chemically peculiar stars. The results are in good agreement with recent experiments. The predicted uncertainty for oscillator strengths ranges from about 5 to 20% and in most cases less than 10% for hyperfine

This paper presents theory andalgorithms for system identification suitable for the framework of behavioral system theory. An algorithm basedon algebraic system theory and realization theory (Ho-Kalman realization) in a subspace model identification framework is presented. The novel approach taken consists of the formulation of input-output data as an impulse response model and the subsequent appl

The aim of this study was to develop all algorithm to automatically calculate infarct transmurality based oil a non dichotomous infarct classification, and to compare with manual delineation. Global transmurality as calculated by the computer algorithm were significantly smaller than the consensus delineation of three observers (p < 0.05). On a regional basis in 6 sectors of each slice the variabi

Weikerts doktorsavhandling i historia definierar offerkyrkor som »en kyrka som av tradition har ansetts besitta en särskild kraft, vilket gjorde att en gåva – eller offer – där ansågs öka chansen till bönhörelse». De flesta finns i Skara och Växjö stift. Sin höjdpunkt nådde offrandet under slutet av 1600-talet och början av 1700-talet. Givarnas ursprung och attityderna vid visitationer har undersö

We give some new examples of bounded multilinear forms on the Hilbert spaces l(2) and L-2(0, infinity). We characterize those which are compact or Hilbert-Schmidt. In particular, we study m-linear forms (m >= 3) on l(2) which can be regarded as the multilinear analogue of the famous Hilbert matrix. We also determine the norm of the permanent on K-n, where K = R or C.
