The increase of total choline in tumors has become an important biomarker in cancer diagnosis. Choline and choline metabolites can be measured in vivo and in vitro using multinuclear MRS. Recent in vivo C-13 MRS studies using labeled substrates enhanced via dynamic nuclear polarization demonstrated the tremendous potential of hyperpolarization for real-time metabolic studies. The present study dem
Purpose – The purpose of this paper is to investigate how food manufacturers in Sweden define and view innovations, how they view their role and those of other actors and the interaction/collaboration regarding innovations in the food supply/value chain. Design/methodology/approach – After an exploratory pre-study with 12 participants, a full study of Swedish manufacturers comprised of represent
A measure of individual differences in the motivation to control in-group bias (favouritism) was created. As in Plant and Devine’s (1998) measure of out-group bias, one subscale referred to an internal motivational source and the other to an external motivational source. The psychometric properties of the measure were tested across four samples. The results indicate that the measure reliably capt
Production of polyhydroxyalkanoates (PHAs) in activated sludge treating wastewater represents an economical and environmental promising alternative to pure culture fermentations. A process for production of PHA from a paper mill wastewater was examined at laboratory scale. The three stage process examined consisted of acidogenic fermentation to convert wastewater organic matter to volatile fatty a
This article analyzes the development of the practice for receiving non-Orthodox in Greek Orthodox canon law. The main argument is that the development of this canonical institution was influenced by a pneumatological realist ecclesiology. This historical study of the development of a canonical institution will shed light on how Greek Orthodox canon law has functioned in practice.
In a recent study,Westerlund (Empir Econ 37:517–531, 2009) shows that the performance of the popular LLC (Levin et al., J Econ 108:1–24, 2002) panel unit root test depends critically on the choice of lag truncation used when correcting for serial correlation, and that it is only when this parameter is set as a function of time that the power raises above size. The purpose of the current paper is t
This article describes the process of professionalisation in the field of social control in Sweden. The aim is to analyse how the state by legislation created the profession of social workers for local social services and thus for social control by public administration. We show how organisations for social work have developed and played an important role since the 19th century and that social inv
OBJECTIVES: Development of guidelines for quality assurance in head injury care has to be based on knowledge about how today's management is organized. To address the need for guidelines in minor head injury (MHI), the authors studied management practice in Sweden. METHODS: We performed a cross-sectional mail survey including all 76 hospitals treating head-injured patients. The questionnaire outli
The effects of a new calcium antagonist, isradipine (PN 200-110) on postpartum uterine activity and the maternal cardiovascular system were investigated. Uterine activity was recorded by a microtip transducer catheter inserted transcervically within 45 min of normal vaginal delivery. 0.5 mg of isradipine was given as a bolus injection during 5 min to 7 women with spontaneous uterine activity and 1
The self-assembly behavior of a cationic surfactant (dodecyltrimethylammonium, DTA) with DNA as counterion in mixtures of water and n-alcohols (decanol, octanol, hexanol, butanol, and ethanol) was investigated. The phase diagrams were established and the different regions of the phase diagram characterized with respect to microstructure by H-2 NMR, small-angle X-ray scattering (SAXS), and other te
Periconceptional use of folic acid is thought to reduce the risk for both neural tube defects and other congenital malformations. Most published data were obtained retrospectively. We used the Swedish Medical Birth Registry to study congenital malformations in infants born of women who reported the use of folic acid in early pregnancy (of which 70% probably used it also preconceptionally) and comp
This investigation concerns numerical calculation of fully developed turbulent forced convective heat transfer and fluid flow in ducts over a wide range of Reynolds numbers. The low Reynolds number version of a non-linear eddy viscosity model is combined with a two-equation heat flux model with the eddy diffusivity concept. The model can theoretically be used for a range of Prandtl numbers or a ra
BACKGROUND: The acquisition of drug resistance is a major reason for poor outcome of neuroblastoma. Protein kinase C (PKC) has been suggested to influence drug resistance in cancer cells. The aim of this study was to elucidate whether inhibition of PKCbeta isoforms influences drug-resistance of neuroblastoma cells. METHODS: The effect of the PKCbeta inhibitor LY379196 on the growth-suppressing eff
An efficient and modular synthesis of a chiral, amphiphilic, and fluorescent macrocycle is described. A bis-acetylene was prepared by coupling the amino group of a sugar delta-amino acid with a glutamic acid propargylic amide derivative, followed by coupling of the sugar delta-amino acid carboxy group with a glutamic acid propiolyl amide. The bis-acetylene was reacted with 9,10-bis(azidomethyl)ant
A new method of correction of instrumental shifts and gain changes observed in experimental spectra is presented. An application of the method to the data collected in a large scale in-beam gamma-ray spectroscopy experiment is discussed.
A class of spherical functions is studied which can be viewed as the matrix generalization of Bessel functions. We derive a recursive structure for these functions. We show that they are only special cases of more general radial functions which also have a properly generalized, recursive structure. Some explicit results are worked out. For the first time, we identify a subclass of such radial func
There is a need for mathematical modelling for the evaluation of important parameters for photon imaging systems. A Monte Carlo program which simulates medical imaging nuclear detectors has been developed. Different materials can be chosen for the detector, a cover and a phantom. Cylindrical, spherical, rectangular and more complex phantom and source shapes can be simulated. Photoelectric, incoher
