An ab initio study of the relative stabilities and equations of state of Fe3S polymorphs
Authors: Martin P. , Vočadlo L. , Alfè D. , Price G. D. 
Published: November 2004

AbstractAn investigation of the relative stabilities and equations of state of possible Fe3S polymorphs was conducted using first-principles pseudopotential calculations. These calculations were based on density functional theory and performed using ultrasoft Vanderbilt pseudopotentials within the generalized gradient approximation. In accord with experiment, we found that the tetragonal Fe3P-type polymorph is the only stable phase along the 0 K isotherm as a function of pressure. Fe3S exhibits permanent magnetism at ambient conditions (Fei et al., 2000), but magnetism is suppressed by pressure and temperature, and therefore non-magnetic data are appropriate ones to use for modelling planetary interiors. For this reason, and because the Fe3P-type polymorph of Fe3S contains 32 atoms per unit cell it was impractical to incorporate magnetic properties into the simulations of this phase, we studied the behaviour of the non-magnetic phase. We obtained values of 250 GPa for the bulk modulus, K0, and 4.61 for its first derivative withrespect to pressure, K0′, by fitting a 3rd order Birch-Murnaghan equation of state to the calculated internal energy as a function of volume for the non-magnetic Fe3P-type Fe3S. This suggests that a pressure far greater than that expected in the Martian interior would be needed to achieve a density comparable to that of the Martian core. We therefore conclude that it is unlikely that the core of Mars contains significant amounts of solid Fe3S.
Protein 4.1R regulates interphase microtubule organization at the centrosome

Published: November 2004

In human red blood cells, protein 4.1 (4.1R) stabilizes the spectrin-actin network and anchors it to the plasma membrane. To contribute to the characterization of functional roles of 4.1R in nonerythroid cells, we analysed the effect of ectopic expression of 4.1R isoforms on interphase microtubules in fibroblastic cells. We found that specific 4.1R isoforms disturbed the microtubule architecture but not the actin cytoskeleton. Biochemical sedimentation and/or confocal microscopy analyses showed that the pericentriolar components γ-tubulin and pericentrin remained at centrosomes, whereas the distributions of proteins p150Glued and the dynein intermediate chain were altered. Remarkably, 4.1R was displaced from the centrosome. In microtubule depolymerizing-repolymerizing assays, 4.1R-transfected cells showed an ability to depolymerize and nucleate microtubules that was similar to that of untransfected cells; however, microtubules became disorganized soon after regrowth. In microtubule-depolymerized transfected cells and during the initial steps of microtubule regrowth, centrosomal 4.1R localized with γ-tubulin but did not when microtubules became disorganized.
To learn more about centrosomal 4.1R function, isolated centrosomes were examined by confocal microscopy, western blot and in vitro microtubule aster-assembly assays. The experiments showed that 4.1R was present in isolated centrosome preparations, that it remained in the center of in-vitro-assembled microtubule asters and that more asters were assembled by the addition of protein 4.1R fused to glutathione-S-transferase. Together, these results indicate that 4.1R plays a key role at the centrosome, contributing to the maintenance of a radial microtubule organization.
Oxidation of Aldehydes on TiO2 Photocatalysts Modified with Alkylsilyl Group

Published: November 2004

Abstract
Surfaces of SiO2-covered TiO2 photocatalysts were modified with alkylsilyl groups. Oxidation of hexanal on surface-modified TiO2 proceeded more efficiently than that on photocatalysts without surface modification. The improvement of the photocatalytic activities of surface-modified TiO2 photocatalysts is due to the hydrophobic interaction between hexanal and alkylsilyl groups modified on TiO2 photocatalysts.

Published: November 2004

AbstractBackground: The calcineurin inhibitors cyclosporine and tacrolimus are used as primary immunosuppressive drugs in transplant patients. Measuring calcineurin phosphatase (CaN) activity is a proposed pharmacodynamic approach to optimize dosing of these drugs.Methods: Whole blood samples were obtained from 10 patients treated with calcineurin inhibitors and 20 healthy volunteers and frozen at −80 °C. CaN activity was measured by its ability to dephosphorylate a 19-amino acid peptide previously phosphorylated with [γ-32P]ATP. Radioactivity was quantified by liquid scintillation, and results were converted from cpm to U of CaN. Validation of the assay included enzyme kinetics, linearity, precision (at low and normal CaN activities), analytical recovery, and limit of detection.Results: The enzyme followed simple Michaelis-Menten-type kinetics: Vmax was estimated as 240 nmol 32P · L−1 · min−1 and Km as 70 μmol/L. The assay was linear within the concentration range examined. Analytical recovery varied from 68% to 72%. The total analytical SD was 0.059 and 0.053 U of CaN for high and low CaN activity, respectively. The within-day SD for high and low activity was 0.032 and 0.039 U of CaN, respectively. The limit of detection was 0.04 U of CaN, which is far below the values measured in patients treated with CaN inhibitors.Conclusions: In addition to the pharmacokinetic monitoring applied today, the CaN assay can be used to monitor patients treated with calcineurin inhibitors, hopefully leading to prolonged graft survival.
Ein bordautonomes Verfahren zur Echtzeitschätzung von Bahn und Lage eines Satelliten mithilfe von Bildbewegungsverfolgung (Autonomous Estimation of Satellite Position and Attitude in Real Time Using Image Motion Tracking)
Authors: Dyblenko Serguei , Janschek Klaus 
Published: November 2004

Abstract
Der vorliegende Beitrag präsentiert ein neuartiges Konzept zur autonomen Navigation von Satelliten. Das Verfahren basiert auf der Analyse von Bewegungsvektoren in der Bildebene einer Bordkamera durch Auswerten von Sequenzen der Kamerabilder. Dies ermöglicht eine Reduzierung von benötigten A-priori-Daten im Vergleich zu bekannten Landmarkenverfahren. Das vorgeschlagene Navigationsverfahren ermöglicht sowohl die Ermittlung der Bahnparameter als auch der Lage des Satelliten. Das Konzept bildet somit die Basis für einen autonomen Satellitenbetrieb und ist speziell geeignet für Missionen zu anderen Planeten. Im Beitrag werden die methodischen Grundlagen des Verfahrens vorgestellt, sowie die erreichbaren Leistungen für einige Planeten sowie konzeptbedingte Einschränkungen präsentiert.

The Time of Circumcision
Authors: King Andrew 
Published: November 2004

At night, before sleep, I hear the bells outside my house. The circumcision candidate and his young male relatives wear them draped from wrists and ankles. During July and August they run, perhaps 30 kilometers a day: to Matendi and Kapchai, to Mwahweya, and down into the Chwele Valley, paying their respects to their families, gathering strength to face the knife.The chants rise and fall above tinkling bells, "Hmmmm, Huwaaaah, Hmmmmmm, Huwaaaaaah." Lying in bed, late, I hear the procession coming down the footpath. Sometimes, instead of passing, they linger to dance and sing a few feet beyond the mud wall. Then the sounds fade out gradually, down the path to Mwahweya and the farms to the east at Matendi.

The Pollution of Incontinence and the Dirty Work of Caregiving in a U.S. Nursing Home
Authors: Jervis Lori L. 
Published: November 2004

In U.S. nursing homes, it is the job of nursing assistants to tend to residents ' basic bodily needs, including elimination and incontinence care.Given their frequent contact with pollutants, aides are very much at risk of becoming “pollutedpeople.” In this article, I investigate how nursing assistants' continual contact with contaminating substances impacts their status within the workplace, their relationships with others, and their attitudes toward their work and themselves as workers. I also explore how aides manage their encounters with pollutants and their stigmatized role as “dirty workers.” In doing so, I hope to explicate the meaning of elimination and of incontinence caregiving in the United States, [nursing homes, caregiving, symbolic pollution, incontinence, American culture]

Clinical, Histologic, and Transcriptomic Evaluation of Sequential Fat Grafting for Morphea
Authors: Liu Juzi , Wang Jing , Zhang Qian , Lu Feng , Cai Junrong 
Published: February 2024

ImportanceMorphea is a rare disease of unknown etiology without satisfactory treatment for skin sclerosis and soft tissue atrophy.ObjectiveTo provide clinical, histologic, and transcriptome evidence of the antisclerotic and regenerative effects of sequential fat grafting with fresh fat and cryopreserved stromal vascular fraction gel (SVF gel) for morphea.Design, Setting, and ParticipantsThis single-center, nonrandomized controlled trial was conducted between January 2022 and March 2023 in the Department of Plastic and Reconstructive Surgery of Nanfang Hospital, Southern Medical University and included adult participants with early-onset or late-onset morphea who presented with varying degrees of skin sclerosis and soft tissue defect.InterventionsGroup 1 received sequential grafting of fresh fat and cryopreserved SVF gel (at 1 and 2 months postoperation). Group 2 received single autologous fat grafting. All patients were included in a 12-month follow-up.Main Outcome and MeasuresThe primary outcome included changes in the modified Localized Scleroderma Skin Severity Index (mLoSSI) and Localized Scleroderma Skin Damage Index (LoSDI) scores as evaluated by 2 independent blinded dermatologists. The histologic and transcriptome changes of morphea skin lesions were also evaluated.ResultsOf 44 patients (median [IQR] age, 26 [23-33] years; 36 women [81.8%]) enrolled, 24 (54.5%) were assigned to group 1 and 20 (45.5%) to group 2. No serious adverse events were noted. The mean (SD) mLoSSI scores at 12 months showed a 1.6 (1.50) decrease in group 1 and 0.9 (1.46) in group 2 (P = .13), whereas the mean (SD) LoSDI scores at 12 months showed a 4.3 (1.34) decrease in group 1 and 2.1 (1.07) in group 2 (P &amp;lt; .001), indicating that group 1 had more significant improvement in morphea skin damage but not disease activity compared with group 2. Histologic analysis showed improved skin regeneration and reduced skin sclerosis in group 1, whereas skin biopsy specimens of group 2 patients did not show significant change. Transcriptome analysis of skin biopsy specimens from group 1 patients suggested that tumor necrosis factor α signaling via NFκB might contribute to the immunosuppressive and antifibrotic effect of sequential fat grafting. A total of 15 hub genes were captured, among which many associated with morphea pathogenesis were downregulated and validated by immunohistochemistry, such as EDN1, PAI-1, and CTGF.Conclusions and RelevanceThe results of this nonrandomized trial suggest that sequential fat grafting with fresh fat and cryopreserved SVF gel was safe and its therapeutic effect was superior to that of single autologous fat grafting with improved mLoSSI and LoSDI scores. Histological and transcriptomic changes further support the effectiveness after treatment.Trial RegistrationChinese Clinical Trial Registry identifier: ChiCTR2200058003

ImportancePrenatal maternal inflammation has been associated with major depressive disorder in offspring in adulthood as well as with internalizing and externalizing symptoms in childhood; however, the association between prenatal inflammation and offspring depression in adolescence has yet to be examined.ObjectiveTo determine whether maternal levels of inflammatory biomarkers during pregnancy are associated with depressive symptomatology in adolescent-aged offspring and to examine how gestational timing, offspring sex, and childhood psychiatric symptoms impact these associations.Design, Setting, and ParticipantsThis was an observational study of a population-based birth cohort from the Child Health and Development Studies (CHDS), which recruited almost all mothers receiving obstetric care from the Kaiser Foundation Health Plan (KFHP) in Alameda County, California, between June 1959 and September 1966. Pregnancy data and blood sera were collected from mothers, and offspring psychiatric symptom data were collected in childhood (ages 9-11 years) and adolescence (ages 15-17 years). Mother-offspring dyads with available maternal prenatal inflammatory biomarkers during first and/or second trimesters and offspring depressive symptom data at adolescent follow-up were included. Data analyses took place between March 2020 and June 2023.ExposuresLevels of inflammatory biomarkers (interleukin 6 [IL-6], IL-8, IL-1 receptor antagonist [IL-1RA], and soluble tumor necrosis factor receptor-II) assayed from maternal sera in the first and second trimesters of pregnancy.Main Outcomes and MeasuresSelf-reported depressive symptoms at adolescent follow-up.ResultsA total of 674 mothers (mean [SD] age, 28.1 [5.9] years) and their offspring (350 male and 325 female) were included in this study. Higher second trimester IL-6 was significantly associated with greater depressive symptoms in offspring during adolescence (b, 0.57; SE, 0.26); P = .03). Moderated mediation analyses showed that childhood externalizing symptoms significantly mediated the association between first trimester IL-6 and adolescent depressive symptoms in male offspring (b, 0.18; 95% CI, 0.02-0.47), while childhood internalizing symptoms mediated the association between second trimester IL-1RA and adolescent depressive symptoms in female offspring (b, 0.80; 95% CI, 0.19-1.75).Conclusions and RelevanceIn this study, prenatal maternal inflammation was associated with depressive symptoms in adolescent-aged offspring. The findings of the study suggest that pathways to adolescent depressive symptomatology from prenatal risk factors may differ based on both the timing of exposure to prenatal inflammation and offspring sex.
