Gene transfer of RANTES elicits autoimmune renal injury in MRL-Faslpr mice

Infiltrating macrophages and T cells are instrumental in autoimmune kidney destruction of MRL-Faslpr mice. We report that the β-chemokine RANTES, a chemoattractant for macrophages and T cells, is up-regulated in the MRL-Faslpr kidney prior to injury, but not normal kidneys (MRL-++, C3H-++) and increases with progressive injury. Furthermore, we establish an association between RANTES expression in the kidney and renal damage using a gene transfer approach. Tubular epithelial cells genetically modified to secrete RANTES infused under the renal capsule incites interstitial nephritis in MRL-Faslpr, but not MRL-++ or C3H-++ mice. RANTES recruits predominantly macrophages (Mø) and CD4+ and CD8+ T cells. In contrast, gene transfer of CSF-1, another molecule up-regulated simultaneously with RANTES in MRL-Faslpr kidneys, promotes the influx of Mø, CD4+ T cells and the unique double-negative (DN) T cells (CD4-,CD8-), which are prominent in diseased MRL-Faslpr kidneys. Thus, RANTES and CSF-1 recruit distinct T cell populations into the MRL-Faslpr kidney. In addition, delivery of RANTES and CSF-1 into the kidney of MRL-Faslpr mice causes an additive increase in pathology. We suggest that the complementary recruitment of T cell populations by RANTES (CD4, CD8) and CSF-1 (CD4, DN) promotes autoimmune nephritis in MRL-Faslpr mice

Prayer as Interpersonal Coping in the Lives of Mothers with HIV

The spirituality of 22 mothers diagnosed with HIV was explored through face-to-face interviews and revealed that 95% of the mothers pray. Active prayers (e.g., talking to God by adoring, thanking, confessing, and supplicating) were more frequently reported than receptive prayers (e.g., quietly listening to God, being open, surrendering). Supplicatory or petitionary prayers for help and health were the most frequent type of prayer, and adoration was the least frequent. The majority of mothers in the sample perceived prayer as a positive coping mechanism associated with outcomes such as: support, positive attitude/affect, and peace. Overall, results supported expanding the boundary conditions of the interpersonal coping component of the Social Interaction Model (Derlega & Barbee, 1998) to include the spiritual dimension of prayer

The ultra high resolution XUV spectroheliograph: An attached payload for the Space Station Freedom

The principle goal of the ultra high resolution XUV spectroheliograph (UHRXS) is to improve the ability to identify and understand the fundamental physical processes that shape the structure and dynamics of the solar chromosphere and corona. The ability of the UHRXS imaging telescope and spectrographs to resolve fine scale structures over a broad wavelength (and hence temperature) range is critical to this mission. The scientific objectives and instrumental capabilities of the UHRXS investigation are reviewed before proceeding to a discussion of the expected performance of the UHRXS observatory

Expanding Hardware-in-the-Loop Formation Navigation and Control with Radio Frequency Crosslink Ranging

The Formation Flying Testbed (FFTB) at the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC) provides a hardware-in-the-loop test environment for formation navigation and control. The facility continues to evolve as a modular, hybrid, dynamic simulation facility for end-to-end guidance, navigation, and control (GN&C) design and analysis of formation flying spacecraft. The core capabilities of the FFTB, as a platform for testing critical hardware and software algorithms in-the-loop, are reviewed with a focus on recent improvements. With the most recent improvement, in support of Technology Readiness Level (TRL) 6 testing of the Inter-spacecraft Ranging and Alarm System (IRAS) for the Magnetospheric Multiscale (MMS) mission, the FFTB has significantly expanded its ability to perform realistic simulations that require Radio Frequency (RF) ranging sensors for relative navigation with the Path Emulator for RF Signals (PERFS). The PERFS, currently under development at NASA GSFC, modulates RF signals exchanged between spacecraft. The RF signals are modified to accurately reflect the dynamic environment through which they travel, including the effects of medium, moving platforms, and radiated power

Interfacial Electronic Charge Transfer and Density of States in Short Period Cu/Cr Multilayers

Nanometer period metallic multilayers are ideal structures to investigate electronic phenomena at interfaces between metal films since interfacial atoms comprise a large atomic fraction of the samples. The Cu/Cr binary pair is especially suited to study the interfaces in metals since these elements are mutually insoluble, thus eliminating mixing effects and compound formation and the lattice mismatch is very small. This allows the fabrication of high structural quality Cu/Cr multilayers that have a structure which can be approximated in calculations based on idealized atomic arrangements. The electronic structure of the Cu and the Cr layers in several samples of thin Cu/Cr multilayers were studied using x-ray absorption spectroscopy (XAS). Total electron yield was measured and used to study the white lines at the Cu L{sub 2} and L{sub 3} absorption edges. The white lines at the Cu absorption edges are strongly related to the unoccupied d-orbitals and are used to calculate the amount of charge transfer between the Cr and Cu atoms in interfaces. Analysis of the Cu white lines show a charge transfer of 0.026 electrons/interfacial Cu atom to the interfacial Cr atoms. In the Cu XAS spectra we also observe a van Hove singularity between the L{sub 2} and L{sub 3} absorption edges as expected from the structural analysis. The absorption spectra are compared to partial density of states obtained from a full-potential linear muffin-tin orbital calculation. The calculations support the presence of charge transfer and indicate that it is localized to the first two interfacial layers in both Cu and Cr
