The Contribution of Katherine Luther to the Homelife and Ministry of her Husband Martin

Katherine von Bora Luther does not command a great deal of space in any Church History textbook. What is known about her life is in connection with that of her husband and Reformer Martin Luther. Katherine Luther stands in the shadow of her great husband Martin but it was possible to catch a glimpse of her character and contribution to the homelife and ministry of her husband Martin

A structural systematic study of four isomers of difluoro-N-(3-pyridyl)benzamide

The four isomers 2,4-, (I), 2,5-, (II), 3,4-, (III), and 3,5-difluoro-N-(3-pyridyl)benzamide, (IV), all with formula C12H8F2N2O, display molecular similarity, with interplanar angles between the C6/C5N rings ranging from 2.94 (11)° in (IV) to 4.48 (18)° in (I), although the amide group is twisted from either plane by 18.0 (2)-27.3 (3)°. Compounds (I) and (II) are isostructural but are not isomorphous. Intermolecular N-H...O=C interactions form one-dimensional C(4) chains along [010]. The only other significant interaction is C-H...F. The pyridyl (py) N atom does not participate in hydrogen bonding; the closest H...Npy contact is 2.71 Å in (I) and 2.69 Å in (II). Packing of pairs of one-dimensional chains in a herring-bone fashion occurs via [pi]-stacking interactions. Compounds (III) and (IV) are essentially isomorphous (their a and b unit-cell lengths differ by 9%, due mainly to 3,4-F2 and 3,5-F2 substitution patterns in the arene ring) and are quasi-isostructural. In (III), benzene rotational disorder is present, with the meta F atom occupying both 3- and 5-F positions with site occupancies of 0.809 (4) and 0.191 (4), respectively. The N-H...Npy intermolecular interactions dominate as C(5) chains in tandem with C-H...Npy interactions. C-H...O=C interactions form R22(8) rings about inversion centres, and there are [pi]-[pi] stacks about inversion centres, all combining to form a three-dimensional network. By contrast, (IV) has no strong hydrogen bonds; the N-H...Npy interaction is 0.3 Å longer than in (III). The carbonyl O atom participates only in weak interactions and is surrounded in a square-pyramidal contact geometry with two intramolecular and three intermolecular C-H...O=C interactions. Compounds (III) and (IV) are interesting examples of two isomers with similar unit-cell parameters and gross packing but which display quite different intermolecular interactions at the primary level due to subtle packing differences at the atom/group/ring level arising from differences in the peripheral ring-substitution patterns

Performance of the Roche Total Mycophenolic Acid® assay on the Cobas Integra 400®, Cobas 6000® and comparison to LC-MS/MS in liver transplant patients

Background: Mycophenolic acid (MPA) is an immunosuppressant for which therapeutic drug monitoring (TDM) is performed for optimal prophylaxis and avoidance of toxicity in transplant patients. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is ideally suited for TDM of MPA. There have been several method comparisons of the Roche Total MPA assay, but none have been performed with respect to liver transplant patients. Methods: We validated the Roche Total MPA assay on the Cobas Integra 400 and Cobas 6000 and compared it to a validated LC-MS/MS (API 2000 (TM)) method. Fifty-five EDTA plasma samples from liver transplant patients were measured with the Roche assay on these platforms and compared to the LC-MS/MS results. Results: Validation of the LC-MS/MS, Cobas Integra 400 and 6000 was performed with good results. The LC-MS/MS/Integra 400/Cobas 6000 were linear up to 30, 15 and 17 mg/L, respectively. Imprecision was <10% for LC-MS/MS and <7% for the Roche assay on both platforms. The samples showed good agreement with LC-MS/MS. Passing-Bablok regression analysis showed Cobas Integra (mg/L) = 1.02 x LC-MS/MS (mg/L)-0.50 and Cobas 6000 (mg/L) = 0.98 x LC-MS/MS-0.47. Conclusions: The Roche Total Mycophenolic Acid-assay is suitable for measuring total MPA in plasma from liver transplant patients and is a good alternative for LC-MS/MS

Anchoring Equitable Development: Anchor Institute-Led Models of Housing and Community Development to Strengthen Institutions and Communities

In April 2014, a convening of national housing equity experts was hosted in Jacksonville, Florida by the Jessie Ball duPont Fund. The convening's purpose was to gain insight from national stakeholders on affordable housing and equitable development challenges and opportunities in Jacksonville. From this two-day engagement, a number of major challenges and opportunities facing Jacksonville's housing development were clearly identified. Two of these findings directly inform this research effort.First, to meet the needs of Jacksonville's marginalized communities, an intentional focus on equity must stay at the forefront of community housing and development strategies. Second, if equity-focused development efforts are better aligned with health and/or educational stakeholders, affordable housing and equitable development could blossom in Jacksonville.Stable and affordable housing is essential to educational success and positive health outcomes for families and for communities. While the linkage between housing and educational and health outcomes is clear, educational and health stakeholders have not traditionally been deeply engaged in meeting housing need. Emerging initiatives across the country are countering this disengagement, demonstrating the important role that anchor institutions can play in supporting local housing needs. Community anchor institutions, such as educational entities (particularly higher education) and health care organizations can be powerful institutional resources to support equitable housing and community development. Throughout the nation, successful anchor institute-led housing interventions have been transformational in addressing community housing needs and community revitalization. These efforts have been most effective when equity goals are integrated into the design and implementation of anchor institute-led housing efforts.The following report provides select case studies with a strong social equity focus and comparability to Jacksonville. We identify lessons learned and summarize models which can be equally transformative in Jacksonville from these case studies. We also draw upon recent research and scholarship, and our own interviews with experts and practitioners. The goal of providing these lessons learned and model practices is to help inform, and potentially engage, various anchor institutes in Jacksonville -- organizations with resources that could help meet community housing needs and support equitable community development. This could help strengthen social, educational, economic and health outcomes for all of Jacksonville, including its most vulnerable residents

Fall armyworm (Spodoptera frugiperda Smith) feeding elicits differential defense responses in upland and lowland switchgrass

Switchgrass (Panicum virgatum L.) is a low input, high biomass perennial grass being developed for the bioenergy sector. Upland and lowland cultivars can differ in their responses to insect herbivory. Fall armyworm [FAW; Spodoptera frugiperda JE Smith (Lepidoptera: Noctuidae)] is a generalist pest of many plant species and can feed on switchgrass as well. Here, in two different trials, FAW larval mass were significantly reduced when fed on lowland cultivar Kanlow relative to larvae fed on upland cultivar Summer plants after 10 days. Hormone content of plants indicated elevated levels of the plant defense hormone jasmonic acid (JA) and its bioactive conjugate JA-Ile although significant differences were not observed. Conversely, the precursor to JA, 12-oxo-phytodienoic acid (OPDA) levels were significantly different between FAW fed Summer and Kanlow plants raising the possibility of differential signaling by OPDA in the two cultivars. Global transcriptome analysis revealed a stronger response in Kanlow plant relative to Summer plants. Among these changes were a preferential upregulation of several branches of terpenoid and phenylpropanoid biosynthesis in Kanlow plants suggesting that enhanced biosynthesis or accumulation of antifeedants could have negatively impacted FAW larval mass gain on Kanlow plants relative to Summer plants. A comparison of the switchgrass-FAW RNA-Seq dataset to those from maize-FAW and switchgrass-aphid interactions revealed that key components of plant responses to herbivory, including induction of JA biosynthesis, key transcription factors and JA-inducible genes were apparently conserved in switchgrass and maize. In addition, these data affirm earlier studies with FAW and aphids that the cultivar Kanlow can provide useful genetics for the breeding of switchgrass germplasm with improved insect resistance
