Strengths and limitations of the neurosphere culture system.

After the initial reports of free-floating cultures of neural stem cells termed neurospheres (1,2), a wide array of studies using this promising culture system emerged. In theory, this was a near-perfect system for large-scale production of neural cells for use in cell replacement therapies and to assay for and characterize neural stem cells. More than a decade later, after rigorous scrutiny and a

Automated Calculation of Infarct Transmurality

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

Multilinear forms of Hilbert type and some other distinguished forms

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.

Review of Monica Weikert, I sjukdom och nöd. Offerkyrkoseden i Sverige från 1600-tal till 1800-tal. Göteborg 2004

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

Maximum slope convolutional codes

The slope is an important distance parameter for a convolutional code. It can be used to obtain a lower bound on the active burst distance and in this respect essentially determines the error-correcting capability of the code. An upper bound on the slope of rate R = b/c convolutional codes is derived. A new family of convolutional codes, called the maximum slope (MS) code family, is introduced. Ta

Greening the EU : Power practices, resistances and agenda setting

Between 1970 and 1995, well over 200 directives dealing with environmental problems have been adopted by the European Community. The ambition in this study has been to understand the process whereby environmental concerns have been brought up on the Community agenda and how that agenda has subsequently been shaped. It is argued that by starting from a critical position in ecocentric and feminist t

Laminins in blood vessel development and disease -functional aspects in angiogenesis, atherosclerosis, and muscular dystrophy

Basement membranes are sheet like extracellular matrices that underlie or surround many cell types. They are crucial for key cellular events such as cell migration, proliferation, survival and differentiation. Vital components of all basement membranes are laminins, heterotrimeric combinations of different laminin chain isoforms. The different laminins and their subunits largely have a development

Extended object wavefront sensing based on the correlation spectrum phase

In this paper we investigate the performance of a Fourier based algorithm for fast subpixel shift determination of two mutually shifted images subjected to noise. The algorithm will be used for Shack-Hartmann based adaptive optics correction of images of an extended object subjected to dynamical atmospheric fluctuations. The performance of the algorithm is investigated both analytically and by Mon

The Children’s Revised Impact of Event Scale (CRIES): Validity as a screening instrument for PTSD.

The Children’s Revised Impact of Event Scale (CRIES) is a brief child-friendly measure designed to screen children at risk for Posttraumatic Stress Disorder (PTSD). It has good face and construct validity, a stable factor structure, correlates well with other indices of distress, and has been used to screen very large samples of at-risk-children following a wide range of traumatic events. However,

Pharmacodynamic studies of vancomycin, metronidazole and fusidic acid against Clostridium difficile

Background: Pharmacodynamic studies of antibiotics have attracted great interest in recent years. However, studies on the pharmacodynamics of different antibiotics against Clostridium difficile are scarce. Methods: The postantibiotic effects (PAE) and the postantibiotic sub-minimum inhibitory concentration (MIC) effects (PA SME) of vancomycin, metronidazole and fusidic acid were investigated by vi

Using a generalized vegetation model to simulate vegetation dynamics in northeastern USA

Models based on generalized plant physiological theory represent a promising approach for describing vegetation responses to environmental drivers on large scales but must be tested for their ability to reproduce features of real vegetation. We tested the capability of a generalized vegetation model (LPJ-GUESS) to simulate vegetation structural and compositional dynamics under various disturbance

Free-to-total prostate-specific antigen ratio as a predictor of non-organ-confined prostate cancer (stage pT3)

Objective: To evaluate whether the free-to-total prostate-specific antigen (F/T-PSA) ratio can be used to differentiate between stage pT2 and pT3 prostate cancer. Material and Methods: A total of 176 consecutive patients from the Goteborg Screening Study (median T-PSA 4.2 ng/ml) who underwent radical prostatectomy (without neoadjuvant hormonal therapy) were included in the study. The pT stage was
