Swedish Church Art from the Introduction of the Reformation in 1527 until the Synod in Uppsala 1593

This article is a survey of Swedish church art from the Reformation, introduced in 1527 by Gustav Vasa, until the Uppsala Synod in 1593 andthe beginning of Orthodoxy. The tolerance shown towards the old cultobjects was typical of the Swedish Reformation. At the same time, therewas an almost total cessation in the production and import of sacral art,this mostly for economic reasons, but also because there was no needfor more cult objects. Especially toward the end of the 15th century, therehad been a large influx of such items to the churches. Only in the field of mural painting was there some activity after the Reformation, and about 20 (known) churches were decorated with murals from 1530 to 1590. However, their motifs remained very much in the Catholic tradition with one difference – non-biblical subjects such as saints (apart from St. George and St. Christopher) were excluded. Motifs from the Old Testament dominated and were often put in a typological context. Medieval moralities also lived on: Memento mori (Wheel of Fortune), Vanitas (Love of the Wordily Goods, the Good and Bad Prayers) and Devil-scenes (Shoe-Ella, Asmodeus). Several murals stem from the reign of John III (1567-92), the Vasa king most engaged in ecclesiastical affairs. In 1575 he forced the priests to accept an addition to the Church Ordinance, the Nova OrdinantiaEcclesiastica, which aimed to persuade the Swedish Church to take a  middle position between Catholicism and Protestantism, a thought which isreflected in murals from his time. It is, however, also here that we find proof that Renaissance ideas had come to Sweden: Vices and Virtues (Glanshammar), a painter’s self-portrait (Valö).During the reign of his predecessor Erik XIV (1560-67), a large immigrationof Calvinists to Sweden had taken place. They had drawn the king’s attention to the Decalogue, according to which no images of God were allowed. A possible sign of Calvinist influence is a wooden tablet from 1561 in Storkyrkan in Stockholm, containing eleven quotations from the Bible (in Latin) that stress the importance of the sermon in the service. Also in 1561, the first known Swedish Reformation altarpiece was installed in Västra Husby, Västergötland, with a motif the Last Supper.Thereafter, more and more new altarpieces replaced the old, but their motifs remained more or less the same as in Catholic times (with the above exceptions). A painted, wooden altarpiece from ca. 1600 in Gamleby, Småland, contains the period’s only known protest against Catholicism. In the main part there is a depiction of the Last Judgement, in the predella, all the Apostles are holding keys in silent protest against the Catholic Church’s teachings that only St. Peter was allowed to carry the keys to the gates of Paradise

Exploring the anti-apoptotic role of HAX-1 versus BCL-XL in cytokine-dependent bone marrow-derived cells from mice

AbstractHS-1-associated protein X-1 (HAX-1) is a multi-functional protein that has been implicated in the regulation of apoptosis, cell motility and calcium homeostasis. In the present study, we set out to assess the postulated functional resemblance of HAX-1 to the BCL-2 family of anti-apoptotic proteins using non-transformed, cytokine-dependent murine bone marrow cells as a model system. BCL-XL, but not HAX-1 protected against cytokine withdrawal-induced apoptosis while HAX-1 and BCL-XL significantly reduced thapsigargin-triggered (calcium-dependent) apoptosis. The data argue in favor of cell type- and stimulus-specific roles of HAX-1 in regulation of cell survival

Gene Expression Profiling and Chromatin Immunoprecipitation Identify DBN1, SETMAR and HIG2 as Direct Targets of SOX11 in Mantle Cell Lymphoma

The SRY (sex determining region Y)-box 11 (SOX11) gene, located on chromosome 2p25, encodes for a transcription factor that is involved in tissue remodeling during embryogenesis and is crucial for neurogenesis. The role for SOX11 in hematopoiesis has not yet been defined. Two genes under direct control of SOX11 are the class- III β-tubulin gene (TUBB3) in neural cells and the transcription factor TEA domain family member 2 (TEAD2) in neural and mesenchymal progenitor cells. Normal, mature lymphocytes lack SOX11 but express SOX4, another member of the same group of SOX transcription factors. We and others recently identified SOX11 as aberrantly expressed in mantle cell lymphoma (MCL). Since SOX11 is variably expressed in MCL it may not be essential for tumorigenesis, but may carry prognostic information. Currently, no specific functional effects have been linked to SOX11 expression in MCL and it is not known which genes are under influence of SOX11 in lymphoma. In this study we found variable expression of SOX11, SOX4 and SOX12 mRNA in mantle cell lymphoma cell lines. Downregulation of SOX11 expression by siRNA verified that SOX11 controlled the expression of the gene TUBB3 in the MCL cell line Granta 519. Furthermore we identified, by global gene expression analysis, 26 new target genes influenced by siRNA SOX11 downmodulation. Among these genes, DBN1, SETMAR and HIG2 were found to be significantly correlated to SOX11 expression in two cohorts of primary mantle cell lymphomas. Chromatin immunoprecipitation (ChIP) analysis showed that these genes are direct targets of the SOX11 protein. In spite of almost complete downregulation of the SOX11 protein no significant effects on Granta 519 cell proliferation or survival in short term in vitro experiments was found. In summary we have identified a number of genes influenced by SOX11 expression in MCL cell lines and primary MCL. Among these genes, DBN1, SETMAR and HIG2 are direct transcriptional targets of the SOX11 protein

Transfer of Small Resting B Cells into Immunodeficient Hosts Results in the Selection of a Self-renewing Activated B Cell Population

We studied the role of bone marrow B cell production in the renewal of peripheral B cells and the feedback mechanisms that control the entry of newly formed B cells into the peripheral B cell pools. When resting lymph node B cells are injected into B cell–deficient hosts, a fraction of the transferred cells expands and constitutes a highly selected population that survives for prolonged periods of time by continuous cell renewal at the periphery. Although the number of donor B cells recovered is low, a significant fraction shows an activated phenotype, and the serum immunoglobulin (Ig)M levels are as in normal mice. This population of activated B cells is resistant to replacement by a new cohort of B cells and is able to feedback regulate both the entry of newly formed B cells into the peripheral pool and terminal differentiation. These findings suggest that peripheral B cell selection follows the first come, first served rule and that IgM-secreting cells are generated from a pool of stable activated B cells with an independent homeostasis

An outbreak of aseptic meningitis due to echovirus 30 associated with attending school and swimming in pools

Summary Objectives To identify the risk factors of an outbreak of meningitis associated with echovirus 30-infection that occurred in Rome, Italy, in late 1997 among children from two different schools. Methods A case-control study was carried out. A case was defined as a child from either of the two schools, A or B, who presented meningitis-like (fever, headache and vomiting), diarrhea, or respiratory tract symptoms. All asymptomatic students were included in the analysis as controls. Results Among 446 pupils (80%) who answered the questionnaire, 68 met the case definition. Twenty pupils developed a meningitis-like illness. Echovirus 30 was isolated from cerebrospinal fluid (CSF) in four and from stools in six. Forty-eight pupils reported other symptoms. The attack rate was 10.8% in school A and 0.8% in school B for meningitis-like illness; it was 12% and 10%, respectively, for other enterovirus-like illnesses. The risk of meningitis-like illness was higher among children attending school A (crude OR=14.9; 95% CI=4.3–52.1), among children using any public pool (OR=3.8; 95% CI=1.5–9.9) and those using an outside swimming pool X (OR=13.4; 95% CI=2.7–65.8 versus no swimming pool and OR=8.3; 95% CI=1.1–62.6 versus other pools). The epidemic curve appears to suggest a person-to-person transmission. Conclusions The epidemic occurred by person-to-person transmission in a number of classrooms and at swimming pool X

Performance of Detecting IgM Antibodies against Enterovirus 71 for Early Diagnosis

Enterovirus 71 (EV71) infection is more likely to induce severe complications and mortality than other enteroviruses. Methods for detection of IgM antibody against EV71 had been established for years, however, the performance of the methods in the very early diagnosis of EV71 infection had not been fully evaluated, which is especially meaningful because of the short incubation period of EV71 infection. In this report, the performance of an IgM anti-EV71 assay was evaluated using acute sera collected from 165 EV71 infected patients, 165 patients infected with other enteroviruses, and more than 2,000 sera from healthy children or children with other infected diseases. The results showed a 90% sensitivity in 20 patients who were in their first illness day, and similar sensitivity remained till 4 days after onset. After then the sensitivity increased to 95% to 100% for more than one month. The specificity of the assay in non-HFMD children is 99.1% (95% CI: 98.6–99.4), similar as the 99.9% specificity in healthy adults. The cross-reaction rate in patients infected with other non-EV71 enteroviruses was 11.4%. In conclusion, the data here presented show that the detection of IgM anti-EV71 by ELISA affords a reliable, convenient, and prompt diagnosis of EV71 infection

Identification and Typing of Human Enterovirus: A Genomic Barcode Approach

Identification and typing of human enterovirus (HEVs) are important to pathogen detection and therapy. Previous phylogeny-based typing methods are mainly based on multiple sequence alignments of specific genes in the HEVs, but the results are not stable with respect to different choices of genes. Here we report a novel method for identification and typing of HEVs based on information derived from their whole genomes. Specifically, we calculate the k-mer based barcode image for each genome, HEV or other human viruses, for a fixed k, 1<k<7, where a genome barcode is defined in terms of the k-mer frequency distribution across the whole genome for all combinations of k-mers. A phylogenetic tree is constructed using a barcode-based distance and a neighbor-joining method among a set of 443 representative non-HEV human viruses and 395 HEV sequences. The tree shows a clear separation of the HEV viruses from all the non-HEV viruses with 100% accuracy and a separation of the HEVs into four distinct clads with 93.4% consistency with a multiple sequence alignment-based phylogeny. Our detailed analyses of the HEVs having different typing results by the two methods indicate that our results are in better agreement with known information about the HEVs

Ras activation of Erk restores impaired tonic BCR signaling and rescues immature B cell differentiation

B cell receptors (BCRs) generate tonic signals critical for B cell survival and early B cell development. To determine whether these signals also mediate the development of transitional and mature B cells, we examined B cell development using a mouse strain in which nonautoreactive immunoglobulin heavy and light chain–targeted B cells express low surface BCR levels. We found that reduced BCR expression translated into diminished tonic BCR signals that strongly impaired the development of transitional and mature B cells. Constitutive expression of Bcl-2 did not rescue the differentiation of BCR-low B cells, suggesting that this defect was not related to decreased cell survival. In contrast, activation of the Ras pathway rescued the differentiation of BCR-low immature B cells both in vitro and in vivo, whereas extracellular signal-regulated kinase (Erk) inhibition impaired the differentiation of normal immature B cells. These results strongly suggest that tonic BCR signaling mediates the differentiation of immature into transitional and mature B cells via activation of Erk, likely through a pathway requiring Ras
