In vivo proton MR spectroscopy of untreated and treated brain abscesses

MR spectroscopy was performed in three patients with brain abscesses. In two patients, MR spectroscopy revealed end-products of bacterial breakdown (acetate, succinate, amino acids, lactate) in the abscess cysts. In one of these, the spectrum was reversed to a single lactate peak after treatment. In the third patient, MR spectroscopy was performed only after treatment and showed a single nonspecif

Questions of Method in James Dunn's Jesus Remembered

Parts of Dunn's methodology in "Jesus Remembered" (2003) are scrutinised: the meaning of "memory" and whether this is the ultimately attainable object of historiography. I contend that historical research should not content itself with investigating how memories are "fictionalized", i.e. retained in narrative form, but press on to verified judgments on historical facts. "Grand (or: master) narrati

A framework for design tradeoffs

Designs almost always require tradeoffs between competing design choices to meet system requirements. We present a framework for evaluating design choices with respect to meeting competing requirements. Specifically, we develop a model to estimate the performance of a UML design subject to changing levels of security and fault-tolerance. This analysis gives us a way to identify design solutions th

Validation of the Swedish Knee Arthroplasty Register: a postal survey regarding 30,376 knees operated on between 1975 and 1995

The Swedish Knee Arthroplasty Register is dependent on the participating clinics regarding accuracy of information. As the register is prospective, and since revision is used as the endpoint in survival analyses, it is important that all revisions of registered primary arthroplasties are reported. To validate the register, we sent a questionnaire to all living patients with 30,796 knees registered

MR imaging of spinal intramedullary tumors

The MR examinations in 25 patients with intramedullary tumors were analyzed. Seven patients were diagnosed with astrocytoma, 6 ependymoma, 2 unspecified glioma, 3 medulloblastoma, 2 metastasis, one neurinoma, and one teratoma. In 3 patients the diagnosis was uncertain. The tumors frequently involved a large portion of the cord and were often accompanied by intratumor necrosis, cystic degeneration,

Electromagnetic energy flow near metal nanoparticles - II: Algorithms for the calculation of the light scattering of multi-spheres and photon energy transport via linear chains of Ag nanoparticles

We present a new algorithm to calculate the near-field distribution of scattered light of multiple nanospheres based on recursive order-of-scattering (OS) and the matrix inversion approaches, which avoids the divergent problem encountered in origin OS method at the resonance condition. Using this method, we investigate the light-transport properties of linear chains of Ag nanospheres. We found a m

Liver dendritic cells present bacterial antigens and produce cytokines upon Salmonella encounter.

The capacity of murine liver dendritic cells (DC) to present bacterial Ags and produce cytokines after encounter with Salmonella was studied. Freshly isolated, nonparenchymal liver CD11c(+) cells had heterogeneous expression of MHC class II and CD11b and a low level of CD40 and CD86 expression. Characterization of liver DC subsets revealed that CD8alpha(-)CD4(-) double negative cells constituted t

Immuno-arrays for multianalyte analysis of chlorotriazines

In this paper, a novel strategy for multicomponent analysis of two classes of pesticides such as triazines (atrazine and simazine) and phenoxyalkanoic acids (2,4-dichlorophenoxy acetic acid (2,4-D), 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), 4-chlorophenoxyacetic acid (CPOAc), phenoxyacetic acid (POAc)) employing immuno-arrays is demonstrated. The approach is based on cross-reactive arrays of sp

Intraoperative angioscopy may improve the outcome of in situ saphenous vein bypass grafting: a prospective study.

OBJECTIVE: To find out whether intraoperative angioscopic assistance has any effect on graft outcome in patients with critical leg ischemia.Material And Methods: One hundred one patients requiring a below-knee bypass were assigned to undergo in situ saphenous vein bypass with or without intraoperative angioscopic assistance; otherwise treated similarly including preoperative duplex vein mapping, i

Prevalence of self-reported eczema in relation to living environment, socio-economic status and respiratory symptoms assessed in a questionnaire study

BACKGROUND: Potential links between eczema and obstructive pulmonary diseases have been postulated. Previously we have reported the prevalence of upper and lower respiratory diseases and the relation to environmental and socio-economic factors in a randomly selected adult population in southern Sweden using a postal questionnaire.In the present study we wanted to analyse the prevalence of eczema a

Entrepreneurial studies: The dynamic research front of a developing social science

Entrepreneurship research has been built upon a historical foundation grounded in economic change. To understand the development of the field, it is useful to understand the motivations and interests of key scholars and to trace the linkages between these scholars and other authors, from the transient to the contributor. This has been done through a bibliometric analysis of research articles cited

Use of antiemetic drugs during pregnancy in Sweden

Background: More than one-half of all pregnant women suffer from nausea and vomiting during pregnancy (NVP), primarily during the first trimester. Methods: Prospectively ascertained information on drug use during pregnancy was obtained from the Swedish Medical Birth Register during the period July 1, 1995 to 2002. Antiemetics (antiemetic antihistamines, dopamine modulators, and ondansetron) primar

Conservative logarithmic reconstructions and finite volume methods

A class of high-order reconstruction methods based on logarithmic functions is presented. Inspired by Marquina's hyperbolic method, we introduce a double logarithmic ansatz of fifth order of accuracy. Low variation is guaranteed by the ansatz and (slope-) limiting is avoided. The method can reconstruct smooth extrema without order reduction. Fifth order of convergence is verified in a numerical ex

Utbildning av handledare fördjupar undervisningen i samtalsmetodik. Bättre effekt om lärarna fått samma utbildning som de studerande

Läkarstuderande bör få upplevelsebaserad utbildning i samtalsmetodik, och deras handledare bör utbildas på samma sätt. Utbildningen bör, för att få långsiktig effekt, integreras med klinisk praktik och betona problemdefinierande färdigheter. Kurser i konsultationsmetodik anordnades för att dels utveckla läkarnas egna konsultationer, dels utveckla en feedbackmodell att använda i handledning av läka

Comparison of two wavelet-based tools for data mining of urban water networks time series

In this paper, two approaches to data mining of time series have been tested and compared. Both methods are based on the wavelet decomposition of data series and allow the localization of important characteristics of a time series in both the time and frequency domain. The first method is a common method based on the analysis of wavelet power spectra. The second approach is new to the applied fiel
