Song Choices of Swiss Sathya Sai Baba Devotees

The charismatic and controversial Indian guru Sathya Sai Baba is the centre of attention and devotion for a great number of adherents from various national, religious, and ethnic backgrounds. Due to its global spread, the Sathya Sai Baba movement is an ideal case for examining displaced religious practices. Singing is a vital part of the religious practice of Sai devotees. In this article I will discuss the contents and usage of the songbook that Swiss devotees compiled. We can observe the extent to which Indian contents are carried over and how they are supplemented with Swiss songs, but also with songs perceived as being part of a universal spiritual treasury of songs (e.g. Native American, Hebrew or International Christian songs). I will suggest that the concept of de- and reterritorialization helps us to analyze the practices of this global religious community. Additionally, I will argue that the devotees’ choice of songs and their singing practices are indeed a manifestation of their claim to universalism as well as their need to be rooted locally. I will further argue that a globalized religious movement is limited in dealing with the encounter of diverse cultural contents by the strategy of reterritorialization, but beyond that creates a new and supraterritorial cultural context.

Intramural and subserosal echogenic foci on US in large-bowel intussusceptions: prognostic indicator for reducibility?

BACKGROUND: In large-bowel intussusceptions, several US signs are known to indicate a lower likelihood of reducibility by enema. US can demonstrate echogenic dots or lines (foci) in the bowel wall, which might indicate an ischemic bowel. OBJECTIVE: To determine the presence of echogenic intramural and subserosal foci in large-bowel intussusceptions and to evaluate the degree of correlation with reducibility. MATERIALS AND METHODS: Between 2001 and 2008, 74 consecutive US examinations were retrospectively evaluated by two pediatric radiologists for intramural and subserosal echogenic foci, or trapped gas, in the intussusception. The degree of correlation between the sonographic findings and reducibility was evaluated. RESULTS: Of 73 intussusceptions examined by US, 56 (76%) were reducible and 17 (23%) were not reducible. Out of 10 intussusceptions with intramural gas, 11 with subserosal gas, and 14 with intramural and subserosal gas, 8 (80%), 6 (56%), 9 (64%), respectively, were not reducible. The presence of intramural gas or subserosal gas or both predicted a lower chance of reduction, but with regard to the effect of these findings together, intramural gas was the only significant predictor. CONCLUSION: Having intramural gas in large-bowel intussusception significantly decreases the chance of reduction.

Contribution of Starlette, Stella, and AJISAI to the SLR-derived global reference frame

The contribution of Starlette, Stella, and AJI-SAI is currently neglected when defining the International Terrestrial Reference Frame, despite a long time series of precise SLR observations and a huge amount of available data. The inferior accuracy of the orbits of low orbiting geodetic satellites is the main reason for this neglect. The Analysis Centers of the International Laser Ranging Service (ILRS ACs) do, however, consider including low orbiting geodetic satellites for deriving the standard ILRS products based on LAGEOS and Etalon satellites, instead of the sparsely observed, and thus, virtually negligible Etalons. We process ten years of SLR observations to Starlette, Stella, AJISAI, and LAGEOS and we assess the impact of these Low Earth Orbiting (LEO) SLR satellites on the SLR-derived parameters. We study different orbit parameterizations, in particular different arc lengths and the impact of pseudo-stochastic pulses and dynamical orbit parameters on the quality of the solutions. We found that the repeatability of the East and North components of station coordinates, the quality of polar coordinates, and the scale estimates of the reference are improved when combining LAGEOS with low orbiting SLR satellites. In the multi-SLR solutions, the scale and the Z component of geocenter coordinates are less affected by deficiencies in solar radiation pressure modeling than in the LAGEOS-1/2 solutions, due to substantially reduced correlations between the Z geocenter coordinate and empirical orbit parameters. Eventually, we found that the standard values of Center-of-mass corrections (CoM) for geodetic LEO satellites are not valid for the currently operating SLR systems. The variations of station-dependent differential range biases reach 52 and 25 mm for AJISAI and Starlette/Stella, respectively, which is why estimating station dependent range biases or using station-dependent CoM, instead of one value for all SLR stations, is strongly recommended.This clearly indicates that the ILRS effort to produce CoM corrections for each satellite, which are site-specific and depend on the system characteristics at the time of tracking,is very important and needs to be implemented in the SLR data analysis.

Transgenic Expression of Human CD46 on Porcine Endothelium: Effect on Coagulation and Fibrinolytic Cascades During Ex Vivo Human-to-Pig Limb Xenoperfusions

BACKGROUND Dysregulation of the coagulation system due to inflammatory responses and cross-species molecular incompatibilities represents a major obstacle to successful xenotransplantation. We hypothesized that complement inhibition mediated by transgenic expression of human CD46 in pigs might also regulate the coagulation and fibrinolysis cascades and tested this in ex vivo human-to-pig xenoperfusions. METHODS Forelimbs of wild-type and hCD46/HLA-E double transgenic pigs were ex vivo xenoperfused for 12 hours with whole heparinized human blood. Muscle biopsies were stained for galactose-α1,3-galactose, immunoglobulin M, immunoglobulin G, complement, fibrin, tissue factor, fibrinogen-like protein 2, tissue plasminogen activator (tPA), and plasminogen activator inhibitor (PAI)-1. The PAI-1/tPA complexes, D-dimers, and prothrombin fragment F1 + 2 were measured in plasma samples after ex vivo xenoperfusion. RESULTS No differences of galactose expression or deposition of immunoglobulin M and immunoglobulin G were found in xenoperfused tissues of wild type and transgenic limbs. In contrast, significantly lower deposition of C5b-9 (P < 0.0001), fibrin (P = 0.009), and diminished expression of tissue factor (P = 0.005) and fibrinogen-like protein 2 (P = 0.028) were found in xenoperfused tissues of transgenic limbs. Levels of prothrombin fragment F1 + 2 (P = 0.031) and D-dimers (P = 0.044) were significantly lower in plasma samples obtained from transgenic as compared to wild-type pig limb perfusions. The expression of the fibrinolytic marker tPA was significantly higher (P = 0.009), whereas PAI-1 expression (P = 0.022) and PAI-1/tPA complexes in plasma (P = 0.015) were lower after transgenic xenoperfusion as compared to wild-type xenoperfusions. CONCLUSIONS In this human-to-pig xenoperfusion model, complement inhibition by transgenic hCD46 expression led to a significant inhibition of procoagulant and antifibrinolytic pathways.

siRNA mediated knockdown of tissue factor expression in pigs for xenotransplantation.

Acute vascular rejection (AVR), in particular microvascular thrombosis, is an important barrier to successful pig-to-primate xenotransplantation. Here, we report the generation of pigs with decreased tissue factor (TF) levels induced by small interfering (si)RNA-mediated gene silencing. Porcine fibroblasts were transfected with TF-targeting small hairpin (sh)RNA and used for somatic cell nuclear transfer. Offspring were analyzed for siRNA, TF mRNA and TF protein level. Functionality of TF downregulation was investigated by a whole blood clotting test and a flow chamber assay. TF siRNA was expressed in all twelve liveborn piglets. TF mRNA expression was reduced by 94.1 ± 4.7% in TF knockdown (TFkd) fibroblasts compared to wild-type (WT). TF protein expression in PAEC stimulated with 50 ng/mL TNF-α was significantly lower in TFkd pigs (mean fluorescence intensity TFkd: 7136 ± 136 vs. WT: 13 038 ± 1672). TF downregulation significantly increased clotting time (TFkd: 73.3 ± 8.8 min, WT: 45.8 ± 7.7 min, p < 0.0001) and significantly decreased thrombus formation compared to WT (mean thrombus coverage per viewing field in %; WT: 23.5 ± 13.0, TFkd: 2.6 ± 3.7, p < 0.0001). Our data show that a functional knockdown of TF is compatible with normal development and survival of pigs. TF knockdown could be a valuable component in the generation of multi-transgenic pigs for xenotransplantation.
