Johann Sebastian Bach was born on 1685 in Eisenach. By the time he turned 10, Bach found himself an orphan after the death of both of his parents. After working in Weimar, Arnstadt, Mühlhausen, and Köthen Bach signed a contract to become the new organist and teacher at St. Thomas Church Leipzig in 1723 and stayed there until his death. In 1749, Bach tried to fix his failing sight by having surgery the following year, but the operation ended up leaving him completely blind. Few months later, Bach suffered a stroke. He died in Leipzig on July 28, 1750. In recent years, there were some questions whether music of different styles can directly alter cardiovascular parameters, particularly by using Bach's music. In some studies it has been shown that cardiovascular parameters (blood pressure, heart rate) are influenced by music. Listening to classic music (Bach) leads to positive erffects, also music by Italian composters. In contrast, "modern" music, vocal music or songs had no positive effects on cardiovascular parameters. In addition, positive effects on cardiovascular parameters and behavioural patters have been shown in an animal study recently, by Bach's music. Recent studies showed clearly that music influences cardiovascular parameters. It is obvious that classical music (Bach) has benefitial effects, both in humans and in animals. Therefore, the music of the "Thomaskantor" will improve both, quality of life and cardiovascular health. © Georg Thieme Verlag KG Stuttgart · New York.

Artistic forms and complexity.

We discuss the inter-relationship between various concepts of complexity by introducing a complexity 'triangle' featuring objective complexity, subjective complexity and social complexity. Their connections are explored using visual and musical compositions of art. As examples, we quantify the complexity embedded within the paintings of the Jackson Pollock and the musical works of Johann Sebastian Bach. We discuss the challenges inherent in comparisons of the spatial patterns created by Pollock and the sonic patterns created by Bach, including the differing roles that time plays in these investigations. Our results draw attention to some common intriguing characteristics suggesting 'universality' and conjecturing that the fractal nature of art might have an intrinsic value of more general significance.
Bach music in preterm infants: no 'Mozart effect' on resting energy expenditure.

2014-02-01

To study whether Johan Sebastian Bach music has a lowering effect on resting energy expenditure (REE) similar to that of Wolfgang Amadeus Mozart music. Prospective, randomized clinical trial with cross-over in 12 healthy, appropriate weights for gestational age (GA), gavage fed, metabolically stable, preterm infants. Infants were randomized to a 30-min period of either Mozart or Bach music or no music over 3 consecutive days. REE was measured every minute by indirect calorimetry. Three REE measurements were performed in each of 12 infants at age 20±15.8 days. Mean GA was 30.17±2.44 weeks and mean birthweight was 1246±239 g. REE was similar during the first 10-min of all three randomization periods. During the next 10-min period, infants exposed to music by Mozart had a trend toward lower REE than when not exposed to music. This trend became significant during the third 10-min period. In contrast, music by Bach or no music did not affect significantly REE during the whole study. On average, the effect size of Mozart music upon REE was a reduction of 7.7% from baseline. Mozart music significantly lowers REE in preterm infants, whereas Bach music has no similar effect. We speculate that 'Mozart effect' must be taken into account when incorporating music in the therapy of preterm infants, as not all types of music may have similar effects upon REE and growth.
Musician's and physicist's view on tuning keyboard instruments

Lubenow, Martin; Meyn, Jan-Peter

2007-01-01

The simultaneous sound of several voices or instruments requires proper tuning to achieve consonance for certain intervals and chords. Most instruments allow enough frequency variation to enable pure tuning while being played. Keyboard instruments such as organ and piano have given frequencies for individual notes and the tuning must be based on a compromise. The equal temperament is not the only solution, but a special choice. Unequal temperaments produce better results in many cases, because important major thirds and triads are improved. Equal temperament was not propagated by Johann Sebastian Bach, as is often stated in introductory literature on this topic.
Sebastian Kneipp and the Natural Cure Movement of Germany: Between Naturalism and Modern Medicine.

2016-12-01

This study discusses the historical significance of the Natural Cure Movement of Germany, centering on the Kneipp Cure, a form of hydrotherapy practiced by Father Sebastian Kneipp (1821-1897). The Kneipp Cure rested on five main tenets: hydrotherapy, exercise, nutrition, herbalism, and the balance of mind and body. This study illuminates the reception of the Kneipp Cure in the context of the trilateral relationship among the Kneipp Cure, the Natural Cure Movement in general, and modern medicine. The Natural Cure Movement was ideologically based on naturalism, criticizing industrialization and urbanization. There existed various theories and methods in it, yet they shared holism and vitalism as common factors. The Natural Cure Movement of Germany began in the early 19th century. During the late 19th century and the early 20th century, it became merged in the Lebensreformbewegung (life reform movement) which campaigned for temperance, anti-tobacco, and anti-vaccination. The core of the Natural Cure Movement was to advocate the world view that nature should be respected and to recognize the natural healing powers of sunlight, air, water, etc. Among varied natural therapies, hydrotherapy spread out through the activities of some medical doctors and amateur healers such as Johann Siegmund Hahn and Vincenz Prie βnitz. Later, the supporters of hydrotherapy gathered together under the German Society of Naturopathy. Sebastian Kneipp, one of the forefathers of hydrotherapy, is distinguished from other proponents of natural therapies in two aspects. First, he did not refuse to employ vaccination and medication. Second, he sought to be recognized by the medical world through cooperating with medical doctors who supported his treatment. As a result, the Kneipp cure was able to be gradually accepted into the medical world despite the "quackery" controversy between modern medicine and the Natural Cure Movement. Nowadays, the name of Sebastian Kneipp remains deeply engraved on

2006-07-15

Bach1 and Bach2 are evolutionarily related members of the BTB-basic region leucine zipper transcription factor family. We found that Bach2 downregulates cell proliferation of N1E-115 cells and negatively affects their potential to differentiate. Nuclear localization of the cyclin-dependent kinase inhibitor p21 is known to arrest cell cycle progression, and cytoplasmic p21 has been shown to promote neuronal differentiation of N1E-115 cells. We found that ectopic Bach2 causes upregulation of p21 expression in the nucleus and in the cytoplasm in undifferentiated N1E-115 cells. In differentiated cells, Bach2 specifically triggers upregulation of cytoplasmic p21. Our data suggest that Bach2 expression could represent a switch during the process of neuronal differentiation. Bach2 is not expressed in neuronal precursor cells. It would have negative effects on proliferation and differentiation of these cells. In differentiated neuronal cells Bach2 expression is upregulated, which could allow Bach2 to function as a gatekeeper of the differentiated status.

Bach1 is a transcriptional repressor of heme oxygenase-1 (HO-1, a.k.a. HSP-32), which is an inducible enzyme and has anti-oxidation/anti-inflammatory properties shown in various models of organ injuries. Since oxidative stress plays a pivotal role in the pathogenesis of nonalcoholic steatohepatitis (NASH), HO-1 induction would be expected to prevent the development of NASH. In this study, we investigated the influence of Bach1 ablation in mice on the progression of NASH in methionine-choline deficient (MCD) diet model. Bach1 ablation resulted in significant induction of HO-1 mRNA and its activity in the liver. When fed MCD diet, Bach1(-/-) mice exhibited negligible hepatic steatosis compared to pronounced steatohepatitis in wild type mice with 6-fold increase in hepatic triglyceride content. Whereas feeding of MCD diet decreased mRNA expressions of peroxisome proliferator-activated receptor (PPAR) α and microsomal triglyceride transfer protein (MTP) in wild type mice, there were no change in Bach1(-/-) mice. In addition, hepatic concentration of malondialdehyde (MDA), a biomarker for oxidative stress as well as plasma alanine aminotransferase (ALT) was significantly lower in Bach1(-/-) mice. These findings suggest that Bach1 ablation exerts hepatoprotective effect against steatohepatitis presumably via HO-1 induction and may be a potential therapeutic target.

Conformal gravity theories are defined by field equations that determine only the conformal structure of the spacetime manifold. The Bach equations represent an early example of such a theory, we present them here in component form in terms of spin- and boost-weighted spin-coefficients using the compacted spin-coefficient formalism. These equations can be used as an efficient alternative to the standard tensor form. As a simple application we solve the Bach equations for pp-wave and static spherically symmetric spacetimes.

Bach2 is a transcription factor which represses its target genes and plays important roles in the differentiation of B and T lymphoid cells. Bach2-deficient (KO) mice develop severe pulmonary alveolar proteinosis, which is associated with increased numbers of granulocytes and T cells. Bach2 is essential for the regulation of T cells, but its role in the regulation of granulocytes is not clear. Here, we observed increased numbers of eosinophils but not neutrophils in the bone marrow, spleen, peripheral blood, and bronchoalveolar lavage fluids of Bach2 KO mice compared with those of wild-type (WT) mice. Upon co-transplantation of the bone marrow cells from CD45.2 Bach2 KO and CD45.1/CD45.2 double-positive WT mice to irradiated WT CD45.1/CD45.2 mice, the reconstituted numbers of eosinophils were similar between Bach2 KO and WT cells. These results showed that the deficiency of Bach2 in eosinophils did not directly drive the differentiation of eosinophils. To investigate the effect of Bach2 KO CD4 + T cells upon eosinophils, we analyzed Rag2/Bach2-double deficient (dKO) mice which lack lymphocytes including CD4 + T cells. Rag2/Bach2 dKO mice did not show any increase in the numbers of eosinophils. Importantly, Bach2 KO mice showed an increase of interleukin-5 (Il-5) in the sera compared with WT mice. These results suggest that up-regulated functions of CD4 + T cells including secretion of Il-5 resulted in proliferation and/or migration to peripheral tissues of eosinophils in Bach2 KO mice. We propose that Bach2 controls homeostasis of eosinophils via restricting the production of Il-5 in CD4 + T cells.
The Integrative Role of the Sigh in Psychology, Physiology, Pathology, and Neurobiology

PubMed Central

Ramirez, Jan-Marino

2015-01-01

“Sighs, tears, grief, distress” expresses Johann Sebastian Bach in a musical example for the relationship between sighs and deep emotions. This review explores the neurobiological basis of the sigh and its relationship with psychology, physiology, and pathology. Sighs monitor changes in brain states, induce arousal, and reset breathing variability. These behavioral roles homeostatically regulate breathing stability under physiological and pathological conditions. Sighs evoked in hypoxia evoke arousal and thereby become critical for survival. Hypoarousal and failure to sigh have been associated with sudden infant death syndrome. Increased breathing irregularity may provoke excessive sighing and hyperarousal, a behavioral sequence that may play a role in panic disorders. Essential for generating sighs and breathing is the pre-Bötzinger complex. Modulatory and synaptic interactions within this local network and between networks located in the brainstem, cerebellum, cortex, hypothalamus, amygdala, and the periaqueductal gray may govern the relationships between physiology, psychology, and pathology. Unraveling these circuits will lead to a better understanding of how we balance emotions and how emotions become pathological. PMID:24746045

Iron plays the central role in oxygen transport by erythrocytes as a constituent of heme and hemoglobin. The importance of iron and heme is also to be found in their regulatory roles during erythroblast maturation. The transcription factor Bach1 may be involved in their regulatory roles since it is deactivated by direct binding of heme. To address whether Bach1 is involved in the responses of erythroblasts to iron status, low iron conditions that induced severe iron deficiency in mice were established. Under iron deficiency, extensive gene expression changes and mitophagy disorder were induced during maturation of erythroblasts. Bach1 -/- mice showed more severe iron deficiency anemia in the developmental phase of mice and a retarded recovery once iron was replenished when compared with wild-type mice. In the absence of Bach1, the expression of globin genes and Hmox1 (encoding heme oxygenase-1) was de-repressed in erythroblasts under iron deficiency, suggesting that Bach1 represses these genes in erythroblasts under iron deficiency to balance the levels of heme and globin. Moreover, an increase in genome-wide DNA methylation was observed in erythroblasts of Bach1 -/- mice under iron deficiency. These findings reveal the principle role of iron as a regulator of gene expression in erythroblast maturation and suggest that the iron-heme-Bach1 axis is important for a proper adaptation of erythroblast to iron deficiency to avoid toxic aggregates of non-heme globin.

The article about the life and achievements of the apothecary Johann van Beethoven, the younger brother of the composer Ludwig van Beethoven, depicts a vivid picture of life in the 18th, 19t century. Research on archived original documents in Bonn, Vienna and Linz on the Danube made it possible to reveal details about the relationship inside this famous family and describes the hurdles of life of a successful apothecary. In 1776 Johann van Beethoven was born as the fourth child of the Beethoven family, a family of Bonner musicians. In 1790 he began his apprenticeship to become an apothecary at the Bonner "Hofapotheke". Towards the end of 1795 he moved to join his older brothers Ludwig and Karl in Vienna. During his time there he worked as a "subject" in various Viennese pharmacies. However in 1808 he purchased the pharmacy "Zur Goldenen Krone" in Linz on the Danube. His new pharmacy flourished, supplying first the Napoleonic occupation troops, and later the Austrian Military with medicines and field dressing/bandage materials. When in 1812 he married his Housekeeper, his Brother Ludwig opposed harshly, on reasons of social status and on moral grounds. Four years later, in 1816 Johann sold the pharmacy in Linz and founded a new pharmacy in Urfahr, on the opposite bank of the Danube. In 1819 he became a squire (or landowner), when he purchased a manor estate in Gneixendorf, near Krems on the Danube. In spite of his numerous duties as an apothecary and squire, Johann was frequently resident in Vienna, supporting his brother both emotionally and pharmaceutically. At the end of his life Johann sold both his pharmacy and the Gneixendorf estate, and spent his last years as a private gentleman living a dazzling lifestyle in Vienna. He died on January 12th 1848 and was buried in Vienna's "Waldmüllerpark".
Design, implementation, use, and preliminary evaluation of SEBASTIAN, a standards-based Web service for clinical decision support.

Despite their demonstrated ability to improve care quality, clinical decision support systems are not widely used. In part, this limited use is due to the difficulty of sharing medical knowledge in a machine-executable format. To address this problem, we developed a decision support Web service known as SEBASTIAN. In SEBASTIAN, individual knowledge modules define the data requirements for assessing a patient, the conclusions that can be drawn using that data, and instructions on how to generate those conclusions. Using standards-based XML messages transmitted over HTTP, client decision support applications provide patient data to SEBASTIAN and receive patient-specific assessments and recommendations. SEBASTIAN has been used to implement four distinct decision support systems; an architectural overview is provided for one of these systems. Preliminary assessments indicate that SEBASTIAN fulfills all original design objectives, including the re-use of executable medical knowledge across diverse applications and care settings, the straightforward authoring of knowledge modules, and use of the framework to implement decision support applications with significant clinical utility.

Activation of BRCA1/BRCA2-Associated Helicase BACH1 Is Required for Timely Progression through S Phase▿

Kumaraswamy, Easwari; Shiekhattar, Ramin

2007-01-01

BACH1 (also known as FANCJ and BRIP1) is a DNA helicase that directly interacts with the C-terminal BRCT repeat of the breast cancer susceptibility protein BRCA1. Previous biochemical and functional analyses have suggested a role for the BACH1 homolog in Caenorhabditis elegans during DNA replication. Here, we report the association of BACH1 with a distinct BRCA1/BRCA2-containing complex during the S phase of the cell cycle. Depletion of BACH1 or BRCA1 using small interfering RNAs results in delayed entry into the S phase of the cell cycle. Such timely progression through S phase requires the helicase activity of BACH1. Importantly, cells expressing a dominant negative mutation in BACH1 that results in a defective helicase displayed increased activation of DNA damage checkpoints and genomic instability. BACH1 helicase is silenced during the G1 phase of the cell cycle and is activated through a dephosphorylation event as cells enter S phase. These results point to a critical role for BACH1 helicase activity not only in the timely progression through the S phase but also in maintaining genomic stability. PMID:17664283

Objectives Altered immune homeostasis and involvement of T cells has been reported in chronic pancreatitis (CP). We evaluated the role of Bach2 (BTB and CNC homology basic leucine zipper transcription factor 2), a key regulator of immune homeostasis in the chronicity of CP. Methods Expression of Bach2 and T-cell transcription factors, enumeration of BACH2+/CD4+ T-lymphocytes were performed by qRT-PCR and flow cytometry respectively. Bach2silenced human CD4+ T-lymphocytes were exposed to CP tissue extract to assess T-cell lineage commitment. Aryl hydrocarbon receptor (Ahr) and Deubiquitinase enzyme A (DUBA/OTUD5gene) were evaluated as markers of persistent Th17 cell differentiation. Bach2 gene (exons) was sequenced to identify risk variants and functionally validated. Results Decrease in Bach2 (p < 0.0001) and increase (p < 0.001) in TBX21, RORC, Ahr, PRDM1, IL23R mRNA were noted in pancreatic tissues, while BACH2+/CD4+ T-lymphocytes were decreased (p < 0.01) in circulation and tissues. Exposure of Bach2 silenced CD4+ T-lymphocytes to CP tissue extract showed increased Ahr, decreased OTUD5, and enhanced Th17 cell differentiation. Sequencing of Bach2 gene revealed association of novel variant (rs9111 in 5′-UTR) with advanced disease and luciferase assay confirmed its role in Bach2 repression. Conclusion Bach2 repression mediates Th17 cell induced inflammation and rs9111-TT in individuals with primary genetic susceptibility to CP is associated with clinical features of advanced disease.

B lymphocyte-induced maturation protein 1 (Blimp-1) is a key regulator for plasma cell differentiation. Prior to the terminal differentiation into plasma cells, Blimp-1 expression is suppressed in B cells by transcription repressors BTB and CNC homology 2 (Bach2) and B cell lymphoma 6 (Bcl6). Bach2 binds to the Maf recognition element (MARE) of the promoter upstream region of the Blimp-1 gene (Prdm1) by forming a heterodimer with MafK. Bach2 and Bcl6 were found to interact with each other in B cells. While both Bach2 and Bcl6 possess the BTB domain which mediates protein-protein interactions, they interacted in a BTB-independent manner. Bcl6 is known to repress Prdm1 through a Bcl6 recognition element 1 in the intron 5, in which a putative, evolutionarily conserved MARE was identified. Both repressed the expression of a reporter gene containing the intron 5 region depending on the presence of the respective binding sites in 18-81 pre-B cells. Co-expression of Bach2 and Bcl6 resulted in further repression of the reporter plasmid. Chromatin immunoprecipitation assays showed MafK to bind to the intron MARE in various B cell lines, thus suggesting that it binds as a heterodimer with Bach2. Therefore, the interaction between Bach2 and Bcl6 might be crucial for the proper repression of Prdm1 in B cells.

The application of functional genomic analysis of breast cancer metastasis has led to the identification of a growing number of organ-specific metastasis genes, which often function in concert to facilitate different steps of the metastatic cascade. However, the gene regulatory network that controls the expression of these metastasis genes remains largely unknown. Here, we demonstrate a computational approach for the deconvolution of transcriptional networks to discover master regulators of breast cancer bone metastasis. Several known regulators of breast cancer bone metastasis such as Smad4 and HIF1 were identified in our analysis. Experimental validation of the networks revealed BACH1, a basic leucine zipper transcription factor, as the common regulator of several functional metastasis genes, including MMP1 and CXCR4. Ectopic expression of BACH1 enhanced the malignance of breast cancer cells, and conversely, BACH1 knockdown significantly reduced bone metastasis. The expression of BACH1 and its target genes was linked to the higher risk of breast cancer recurrence in patients. This study established BACH1 as the master regulator of breast cancer bone metastasis and provided a paradigm to identify molecular determinants in complex pathological processes. PMID:22875853

The regulation of gene expression in response to environmental signals and metabolic imbalances is a key step in maintaining cellular homeostasis. BTB and CNC homology 1 (BACH1) is a heme-binding transcription factor repressing the transcription from a subset of MAF recognition elements at low intracellular heme levels. Upon heme binding, BACH1 is released from the MAF recognition elements, resulting in increased expression of antioxidant response genes. To systematically address the gene regulatory networks involving BACH1, we combined chromatin immunoprecipitation sequencing analysis of BACH1 target genes in HEK 293 cells with knockdown of BACH1 using three independent types of small interfering RNAs followed by transcriptome profiling using microarrays. The 59 BACH1 target genes identified by chromatin immunoprecipitation sequencing were found highly enriched in genes showing expression changes after BACH1 knockdown, demonstrating the impact of BACH1 repression on transcription. In addition to known and new BACH1 targets involved in heme degradation (HMOX1, FTL, FTH1, ME1, and SLC48A1) and redox regulation (GCLC, GCLM, and SLC7A11), we also discovered BACH1 target genes affecting cell cycle and apoptosis pathways (ITPR2, CALM1, SQSTM1, TFE3, EWSR1, CDK6, BCL2L11, and MAFG) as well as subcellular transport processes (CLSTN1, PSAP, MAPT, and vault RNA). The newly identified impact of BACH1 on genes involved in neurodegenerative processes and proliferation provides an interesting basis for future dissection of BACH1-mediated gene repression in neurodegeneration and virus-induced cancerogenesis.

BTB and CNC homolog 1 (Bach1) is a transcriptional repressor of heme oxygenase-1 (HO-1), which plays an important role in the protection of cells and tissues against acute and chronic inflammation. However, the role of Bach1 in the gastrointestinal mucosal defense system remains little understood. HO-1 supports the suppression of experimental colitis and localizes mainly in macrophages in colonic mucosa. This study was undertaken to elucidate the Bach1/HO-1 system's effects on the pathogenesis of experimental colitis. This study used C57BL/6 (wild-type) and homozygous Bach1-deficient C57BL/6 mice in which colonic damage was induced by the administration of an enema of 2,4,6-trinitrobenzene sulfonic acid (TNBS). Subsequently, they were evaluated macroscopically, histologically, and biochemically. Peritoneal macrophages from the respective mice were isolated and analyzed. Then, wild-type mice were injected with peritoneal macrophages from the respective mice. Acute colitis was induced similarly. TNBS-induced colitis was inhibited in Bach1-deficient mice. TNBS administration increased the expression of HO-1 messenger RNA and protein in colonic mucosa in Bach1-deficient mice. The expression of HO-1 mainly localized in F4/80-immunopositive and CD11b-immunopositive macrophages. Isolated peritoneal macrophages from Bach1-deficient mice highly expressed HO-1 and also manifested M2 macrophage markers, such as Arginase-1, Fizz-1, Ym1, and MRC1. Furthermore, TNBS-induced colitis was inhibited by the transfer of Bach1-deficient macrophages into wild-type mice. Deficiency of Bach1 ameliorated TNBS-induced colitis. Bach1-deficient macrophages played a key role in protection against colitis. Targeting of this mechanism is applicable to cell therapy for human inflammatory bowel disease.

Questing one's personal identity and developing a coherent representation of oneself, the other and the world are major tasks in adolescence. Research showed that a satisfactory resolution of the crisis of adolescence can be favoured by psychological counselling based on artistic mediations. The objective of this study consisted in exploring the effect of music on the pictorial expression of a non clinical sample of female adolescents (N=157) aged from 17 to 28 years. We analysed free drawings realised by the test group with the help of a rating scale constructed in a phenomenological and structural perspective (Schiltz, 2006). The adolescents painted under musical induction. We proposed three different styles of music, i.e. baroque music (Georg Friedrich Händel and Johann Sebastian Bach), classical music (Wolfgang Amadeus Mozart and Ludwig van Beethoven) and polish ethnical music (Kapela ze Wsi Warszawa-Warsaw Village Band). By using non parametric inferential and multi dimensional statistics, we could show that structural characteristics of music styles lead to differences in formal and content variables on the rating scales for the pictures. The results of our exploratory study open some tracks for future research. It would be pertinent to enlarge the population to other categories of age and to investigate the influence of gender.
A Marble Embryo: Meanings of a Portrait from 1900

Portraits of scientists use attributes of discovery to construct identities; portraits that include esoteric accessories may fashion identities for these too. A striking example is a marble bust of the anatomist Wilhelm His by the Leipzig sculptor Carl Seffner. Made in 1900, it depicts the founder of modern human embryology looking down at a model embryo in his right hand. This essay reconstructs the design and viewing of this remarkable portrait in order to shed light on private and public relations between scientists, research objects and audiences. The bust came out of a collaboration to model the face of the composer Johann Sebastian Bach and embodies a shared commitment to anatomical exactitude in three dimensions. His’s research agendas and public character explain the contemplative pose and unprecedented embryo model, which he had laboriously constructed from material a midwife supplied. The early contexts of display in the His home and art exhibitions suggest interpretive resources for viewers and hence likely meanings. Seffner’s work remains exceptional, but has affinities to portraits of human embryologists and embryos produced since 1960. Embryo images have acquired such controversial prominence that the model may engage us more strongly now than it did exhibition visitors around 1900. PMID:22606754
T cell fates ‘zipped up’: how the Bach2 basic leucine zipper transcriptional repressor directs T cell differentiation and function1

Recent data illustrate a key role for the transcriptional regulator Bach2 in orchestrating T cell differentiation and function. Although Bach2 has a well-described role in B cell differentiation, emerging data show that Bach2 is a prototypical member of a novel class of transcription factors that regulates transcriptional activity in T cells at super enhancers, or regions of high transcriptional activity. Accumulating data demonstrate specific roles for Bach2 in favoring regulatory T cell generation, restraining effector T cell differentiation and potentiating memory T cell development. Evidence suggests that Bach2 regulates various facets of T cell function by repressing other key transcriptional regulator such as Blimp-1. This review examines our current understanding of the role of Bach2 in T cell function and highlights the growing evidence that this transcriptional repressor functions as a key regulator involved in maintenance of T cell quiescence, T cell subset differentiation and memory T cell generation.

Jakob Johannes Sederholm (1863-1934) was one of the more influential pioneers in Precambrian geology having introduced some fundamental insights and concepts which are still relevant today. Towards the end of the 19th century, he demonstrated how the principle of actualism can be applied to Precambrian terranes, while during the early part of the 20th century he undertook detailed studies on deformed magmatic rocks, both defining and interpreting the enigmatic mixed rocks now known as migmatites. He acted as the head of the Geological Survey of Finland for 40 years, which developed under his leadership into a modern progressive and versatile research organization. In addition, Sederholm also served as a diplomat with a number of international assignments, including appointments with the League of Nations in missions in Albania and a supervisory role relating to sovereignty and autonomy issues in the Åland Island. Several mountains in Greenland have been named after him and his family, and he was also appointed as honorary chief of two Indian tribes in Canada. To understand the driving forces behind a man of his kind, we focus here on Sederholm the person and some of the social and cultural background that influenced his career. This text is based on the book, published in Swedish, entitled "Jakob Johannes Sederholm, Geolog, humanist och sanningssökare" (Scheinin and Korsman, 2007), and an interview with J.J. Sederholm's granddaughter Barbro Scheinin by Eklund (2008). Other references are marked in the text. The first author is responsible for all translations from Swedish, Norwegian, German and Finnish.

Bach2 Promotes Regulatory T-cell Development by Limiting Effector Differentiation | Center for Cancer Research

Cancer.gov

A number of allergic and autoimmune disorders, such as Crohn’s disease, asthma, type I diabetes and multiple sclerosis, are associated with polymorphisms in a gene encoding the transcription factor, BACH2. Despite this, the mechanism Bach2 uses to prevent immune-mediated diseases was not known. To function appropriately, the immune system relies on a delicate balance between immune-stimulating and immune-regulating cells. When immune-stimulating cells become too active, or immune-regulating cells become ineffective, autoimmune and allergic diseases can ensue.

Johann Leonhard Rost (1688-1727) of Nuremberg studied at Altdorf, Leipzig and Jena. During this time, he earned his living by writing gallant novels. In 1715, he returned to Nuremberg, where he pursued his juvenile inclination towards astronomy and became a serious astronomical observer. His introductions to astronomy, written around this time, contributed a lot to popularize astronomy. This contribution attempts to do justice to both the novelist and the astronomer Rost.

Exposure to the aryl hydrocarbon receptor (AHR) agonist, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) alters B-cell differentiation and suppresses antibody production. Previous genomic studies in mouse B cells identified Bach2 as a direct target of the AHR. Bach2 is known to repress expression of Prdm1, a key transcription factor involved in B-cell differentiation, by binding to Maf elements (MAREs) in the regulatory regions of the gene. Chromatin immunoprecipitation followed by quantitative PCR in TCDD-treated lipopolysaccharide (LPS)-activated B cells showed increased binding of the AHR within the first intron in the Bach2 gene. The binding was further confirmed by electrophoretic mobility shift assay (EMSA). TCDDmore » also induced expression of Bach2 in activated as well as resting B cells from 2 to 24 h post-treatment in a time- and concentration-dependent manner. Expression of Prdm1 was decreased by TCDD at 24 h and was consistent with repression by Bach2. Increased DNA binding activity to the intron 5 MARE with increasing TCDD concentrations was observed by EMSA. Supershifts identified the presence of Bach2 in the DNA binding complex associated with the intron 5 MARE of Prdm1. Functional validation of the role of Bach2 in the suppression of B-cell differentiation by TCDD was performed using RNA interference (RNAi). Knockdown of Bach2 showed approximately 40% reversal in the TCDD-induced suppression of IgM secretion when compared to controls. The results suggest that the transcriptional regulation of Bach2 by the AHR is one of the mechanisms involved in the suppression of B-cell differentiation by TCDD.« less

Mutations in known predisposition genes account for only about a third of all multiple-case breast cancer families. We hypothesized that germline mutations in FANCD2, BRIP1/BACH1, LMO4 and SFN may account for some of the unexplained multiple-case breast cancer families. The families used in this study were ascertained through the Kathleen Cuningham Foundation Consortium for Research into Familial Breast Cancer (kConFab). Denaturing high performance liquid chromatography (DHPLC) analysis of the coding regions of these four genes was conducted in the youngest affected cases of 30 to 267 non-BRCA1/2 breast cancer families. In addition, a further 399 index cases were also screened for mutations in two functionally significant regions of the FANCD2 gene and 253 index cases were screened for two previously reported mutations in BACH1 (p. P47A and p. M299I). DHPLC analysis of FANCD2 identified six silent exonic variants, and a large number of intronic variants, which tagged two common haplotypes. One protein truncating variant was found in BRIP1/BACH1, as well as four missense variants, a silent change and a variant in the 3' untranslated region. No missense or splice site mutations were found in LMO4 or SFN. Analysis of the missense, silent and frameshift variants of FANCD2 and BACH1 in relatives of the index cases, and in a panel of controls, found no evidence suggestive of pathogenicity. There is no evidence that highly penetrant exonic or splice site mutations in FANCD2, BRIP1/BACH1, LMO4 or SFN contribute to familial breast cancer. Large scale association studies will be necessary to determine whether any of the polymorphisms or haplotypes identified in these genes contributes to breast cancer risk.

Probability analysis of the relation of salinity to freshwater discharge in the St. Sebastian River, Florida

1999-01-01

The St. Sebastian River lies in the southern part of the Indian River basin on the east coast of Florida. Increases in freshwater discharge due to urbanization and changes in land use have reduced salinity in the St. Sebastian River and, consequently, salinity in the Indian River, affecting the commercial fishing industry. Wind, water temperature, tidal flux, freshwater discharge, and downstream salinity all affect salinity in the St. Sebastian River estuary, but freshwater discharge is the only one of these hydrologic factors which might be affected by water-management practices. A probability analysis of salinity conditions in the St. Sebastian River estuary, taking into account the effects of freshwater discharge over a period from May 1992 to March 1996, was used to determine the likelihood (probability) that salinities, as represented by daily mean specific- conductance values, will fall below a given threshold. The effects of freshwater discharge on salinities were evaluated with a simple volumetric model fitted to time series of measured specific conductance, by using nonlinear optimization techniques. Specific-conductance values for two depths at monitored sites represent stratified flow which results from differences in salt concentration between freshwater and saltwater. Layering of freshwater and saltwater is assumed, and the model is applied independently to each layer with the assumption that the water within the layer is well mixed. The model of specific conductance as a function of discharge (a salinity response model) was combined with a model of residual variation to produce a total probability model. Flow distributions and model residuals were integrated to produce a salinity distribution and determine differences in salinity probabilities as a result of changes in water-management practices. Two possible management alternatives were analyzed: stormwater detention (reducing the peak rate of discharge but not reducing the overall flow volume) and

Some mathematical aspects of the Music theory by Johannes Kepler are discussed, paying a special attention to the book "De harmonice mundi". Other scientists interested in Music theory are mentioned throughout the paper: The Pythagorean school, Klaudios Ptolemaios, Leonard Euler, Gottfried Wilhelm Leibniz, Christian von Goldbach, Hermann Ludwig Ferdinand von Helmholz, Karl Friedrich Gauss. The relation with the ancient chinese schools of cosmography has been discussed: From the the Pythagorean to the ancient Chinese schools of cosmography we find arithmo-geometrical applications of numbers which are emblematic, hold meaning or represent the essence of things, the author writes. It was Johannes Kepler who taught us this "transconstructive method" of forming classical and ancient begginings of structuralistic thinking into a system from which deductions can readily be made.

Autoimmune disease is one of the leading causes of morbidity and mortality worldwide. In Addison's disease, the adrenal glands are targeted by destructive autoimmunity. Despite being the most common cause of primary adrenal failure, little is known about its aetiology. To understand the genetic background of Addison's disease, we utilized the extensively characterized patients of the Swedish Addison Registry. We developed an extended exome capture array comprising a selected set of 1853 genes and their potential regulatory elements, for the purpose of sequencing 479 patients with Addison's disease and 1394 controls. We identified BACH2 (rs62408233-A, OR = 2.01 (1.71-2.37), P = 1.66 × 10 -15 , MAF 0.46/0.29 in cases/controls) as a novel gene associated with Addison's disease development. We also confirmed the previously known associations with the HLA complex. Whilst BACH2 has been previously reported to associate with organ-specific autoimmune diseases co-inherited with Addison's disease, we have identified BACH2 as a major risk locus in Addison's disease, independent of concomitant autoimmune diseases. Our results may enable future research towards preventive disease treatment. © 2016 The Authors.

Erectile dysfunction (ED) is associated with cardiovascular disease (CVD); however, the association between change in ED status over time and future underlying CVD risk is unclear. The aim of this study was to investigate the association between change in ED status and Framingham CVD risk, as well change in Framingham risk. We studied 965 men free of CVD in the Boston Area Community Health (BACH) Survey, a longitudinal cohort study with three assessments. ED was assessed with the five-item International Index of Erectile Function at BACH I (2002-2005) and BACH II (2007-2010) and classified as no ED/transient ED/persistent ED. CVD risk was assessed with 10-year Framingham CVD risk algorithm at BACH I and BACH III (2010-2012). Linear regression models controlled for baseline age, socio-demographic and lifestyle factors, as well as baseline Framingham risk. Models were also stratified by age (≥/< 50 years). Framingham CVD risk and change in Framingham CVD risk were the main outcome measures. Transient and persistent ED was significantly associated with increased Framingham risk and change in risk over time in univariate and age-adjusted models. In younger men, persistent ED was associated with a Framingham risk that was 1.58 percentage points higher (95% confidence interval [CI]: 0.11, 3.06) and in older men, a Framingham risk that was 2.54 percentage points higher (95% CI: -1.5, 6.59), compared with those without ED. Change in Framingham risk over time was also associated with transient and persistent ED in men <50 years, but not in older men. Data suggest that even after taking into account other CVD risk factors, transient and persistent ED is associated with Framingham CVD risk and a greater increase in Framingham risk over time, particularly in younger men. Findings further support clinical assessment of CVD risk in men presenting with ED, especially those under 50 years. © 2014 International Society for Sexual Medicine.
Surface Water Quality Survey of Northern Indian River Lagoon from Sebastian Inlet to Mosquito Lagoon

2012-12-01

Following news of an emerging brown tide algal bloom in the northern Indian River Lagoon (IRL), researchers sought to gain insight into the surface water quality in the IRL, as well as the extent of the algae coverage. A Portable SeaKeeper from YSI, mounted to a personal watercraft-based coastal profiling system, autonomously collected and analyzed the surface water. The system operates by recording sample data every 12 seconds while continuously underway at speeds up to and greater than 50 km/hr. The researchers covered a transect that started at Sebastian Inlet and followed a zig-zag path extending up through the Haulover Canal and into the Mosquito Lagoon. The survey path covered 166.7 km, and collected 2248 samples. Along the way stops were made at water quality stations used by the Saint John's River Water Management District, so that the data collected can be incorporated into ongoing monitoring efforts. The system analyzed the surface water for dissolved oxygen, pH, chlorophyll-a, salinity, temperature, turbidity, refined fuels, and CDOM. In the two days following the lagoon survey, the inlets at Port Canaveral and Sebastian were also surveyed for tidal currents and hydrography. The IRL transect survey data recorded evidence of the southern extent of the algae bloom in both chlorophyll-a and pH levels. Visual evidence of the bloom was striking as the water in the northern IRL turned a milk chocolaty brown color. Chlorophyll-a levels in the two inlets suggested bloom activity at these locations; however this bloom was different. This oceanic bloom was a result of a persistent upwelling event along the East Florida shelf, and the color was a paler green-yellow. The near-synoptic nature of the comprehensive lagoon survey, conducted in just over 7 hours, allows researchers to obtain a better understanding of water quality in coastal lagoons. Elevated levels of salinity, temperature, and refined fuels in the northern IRL indicate a low exchange rate and absence

The connection between musical theory and astronomy is an aspect of Pythagorean cosmology, which still played a role in the 17th century, and was advanced at that time in very different ways: while Johannes Kepler conceives a proper geometrical system of harmonics and tries to connect it with accurate astronomical data, Athanasius Kircher, harshly criticising Kepler's ideas, sets a qualitative system against it, which is based on analogies. The reason for this discrepancy is not only found in the basically different systems of harmonics of both researchers, but also in the different positions that were taken by both within the controversy about the heliocentric system of the world.

Autoimmune Addison's disease (AAD) is a rare but highly heritable condition. The BACH2 protein plays a crucial role in T lymphocyte maturation, and allelic variation in its gene has been associated with a number of autoimmune conditions. We aimed to determine whether alleles of the rs3757247 single nucleotide polymorphism (SNP) in the BACH2 gene are associated with AAD. This case-control association study was performed in two phases using Taqman chemistry. In the first phase, the rs3757247 SNP was genotyped in 358 UK AAD subjects and 166 local control subjects. Genotype data were also available from 5154 healthy UK controls from the Wellcome Trust (WTCCC2) for comparison. In the second phase, the SNP was genotyped in a validation cohort comprising 317 Norwegian AAD subjects and 365 controls. The frequency of the minor T allele was significantly higher in subjects with AAD from the United Kingdom compared to both the local and WTCCC2 control cohorts (58% vs 45 and 48%, respectively) (local controls, P = 1.1 × 10 -4 ; odds ratio [OR], 1.68; 95% confidence interval [CI], 1.29-2.18; WTCCC2 controls, P = 1.4 × 10 -6 ; OR, 1.44; 95% CI, 1.23-1.69). This finding was replicated in the Norwegian validation cohort (P = .0015; OR, 1.41; 95% CI, 1.14-1.75). Subgroup analysis showed that this association is present in subjects with both isolated AAD (OR, 1.53; 95% CI, 1.22-1.92) and autoimmune polyglandular syndrome type 2 (OR, 1.37; 95% CI, 1.12-1.69) in the UK cohort, and with autoimmune polyglandular syndrome type 2 in the Norwegian cohort (OR, 1.58; 95% CI, 1.22-2.06). We have demonstrated, for the first time, that allelic variability at the BACH2 locus is associated with susceptibility to AAD. Given its association with multiple autoimmune conditions, BACH2 can be considered a "universal" autoimmune susceptibility locus.

Johannes Vermeer of Delft [1632-1675] and vision in neuroendoscopy

Background: Johannes Vermeer of Delft [1632-1675] was one of the greatest Masters of the Dutch Golden Age who was intensely preoccupied with the behavior of light and other optical effects and was entitled “The Master of Light”. He fastidiously attended to the subtleties of visual expression through geometry, composition, and precise mastery of the rules of perspective. It has been our impression that some visual similarity does exist between neuroendoscopic images and some of Vermeer's paintings. Such a relation could be explained by the fact that optical devices are utilized in producing both types of display. Methods: We reviewed the pertinent medical and art literature, observed some video clips of our endoscopy cases, and inspected digital high resolution images of Vermeer's paintings in order to elaborate on shared optical phenomena between neuroendoscopic views and Vermeer's paintings. Results: Specific optical phenomena are indeed shared by Johannes Vermeer's works and neuroendoscopic vision, namely light and color effects as well as the rules of perspective. Conclusion: From the physical point of view, the possibility that a camera obscura inspired Vermeer's artistic creation makes the existence of a visual link between his paintings and the endoscopic views of the intracranial cavity comprehensible.

Abnormal red blood cell (RBC) clearance in β-thalassemia is triggered by activated monocytes. Recent reports indicate that miRNA (miR-) plays a role in monocyte activation. To study phagocytic function, we co-cultured monocytes of normal, non-splenectomized and splenectomized β-thalassemia/HbE individuals with RBCs obtained from normal, non-splenectomized and splenectomized β-thalassemia/HbE individuals. The phagocytic activity of β-thalassemia/HbE monocytes co-cultured with β-thalassemia/HbE RBCs was significantly higher than that of normal monocytes co-cultured with normal RBCs. Upregulation of monocyte miR-155 was observed in β-thalassemia/HbE patients. Increased miR-155 was associated with reductions in BTB and CNC Homology1 (BACH1) target gene expression and increased phagocytic activity of β-thalassemia/HbE monocytes. Taken together, these findings suggested that increased miR-155 expression in activated monocytes leads to enhanced phagocytic activity via BACH-1 regulation in β-thalassemia/HbE. This provides novel insights into the phagocytic clearance of abnormal RBCs in β-thalassemia/HbE.

Genetic studies have to date identified 43 genome wide significant coeliac disease susceptibility (CD) loci comprising over 70 candidate genes. However, how altered regulation of such disease associated genes contributes to CD pathogenesis remains to be elucidated. Recently there has been considerable emphasis on characterising cell type specific and stimulus dependent genetic variants. Therefore in this study we used RNA sequencing to profile over 70 transcriptomes of CD4+ T cells, a cell type crucial for CD pathogenesis, in both stimulated and resting samples from individuals with CD and unaffected controls. We identified extensive transcriptional changes across all conditions, with the previously established CD gene IFNy the most strongly up-regulated gene (log2 fold change 4.6; Padjusted = 2.40x10-11) in CD4+ T cells from CD patients compared to controls. We show a significant correlation of differentially expressed genes with genetic studies of the disease to date (Padjusted = 0.002), and 21 CD candidate susceptibility genes are differentially expressed under one or more of the conditions used in this study. Pathway analysis revealed significant enrichment of immune related processes. Co-expression network analysis identified several modules of coordinately expressed CD genes. Two modules were particularly highly enriched for differentially expressed genes (P<2.2x10-16) and highlighted IFNy and the genetically associated transcription factor BACH2 which showed significantly reduced expression in coeliac samples (log2FC -1.75; Padjusted = 3.6x10-3) as key regulatory genes in CD. Genes regulated by BACH2 were very significantly over-represented among our differentially expressed genes (P<2.2x10-16) indicating that reduced expression of this master regulator of T cell differentiation promotes a pro-inflammatory response and strongly corroborates genetic evidence that BACH2 plays an important role in CD pathogenesis.

At the end of the 18th century the French physicians discussed Johann Georg Zimmermann's medical concepts (i.e. medical experience, the influence of the soul on health and disease). In contrast to the German scientists, the French, especially those from the School of Montpellier, accepted Zimmermann's medical views as a confirmation of vitalism and neohippocratic medicine. In Germany, Zimmermann's medical works fell into oblivion after his death until the middle of 20th century. This may be a consequence of his intimate contacts to the European high nobility and of his polemic attacks against friends and enemies as well as his contempt for all forms of democracy and the French Revolution.

Johannes Heinrich Schultz (1884-1970) established the set of techniques known as "autogenic training." From 1936 until 1945 he worked as assistant director of the Göring Institute. His role during National Socialism has been underestimated in our opinion. We considered Schultz's academic publications and his "autobiography" from 1964. Schultz publicly advocated compulsory sterilization as well as the "annihilation of life unworthy of life" and developed a diagnostic scheme which distinguished between the neurotic/curable and the hereditary/ incurable. In fact, this classification was then employed to decide between life and death. In order to justify the "New German Psychotherapy" alongside eugenic psychiatry, Schultz carried out degrading and inhuman "treatments" of homosexual prisoners of concentration camps who were in mortal danger. This study was based on written documents. We were not able to interview contemporary witnesses. By advocating compulsory sterilization and the "annihilation of life unworthy of life" and by the abuse of homosexuals as research objects Schultz violated fundamental ethical principles of psychiatry.

Johann Gregor Gutturff was a plague barber in the Dresden epidemic of 1680, and important records of his life and work have survived. Largely ignored by plague research, the source material provides detailed insight into the quasi-medical work and everyday life of a plague barber. The sources provide information relating to medical diagnosis and treatment; the barber's relationship to his patients; and the public's perception of the barber and his work. There is also a good deal to be learned relating to Johann Gregor Gutturff himself: his self-perception as a person suffering from plague, his experience under the plague regiment, and other opinions and reflections. Last but not least, this study attests to the existence of numerous unevaluated archival materials, which can be systematically analysed to create new avenues of historical description (historiography) and epidemiology.
Dual regulation of skin sensitizer-induced HMOX1 expression by Bach1 and Nrf2: Comparison to regulation of the AKR1C2-ARE element in the KeratinoSens cell line

Heme oxygenase (decycling) 1 (HMOX1) is the most consistently found genetic marker induced by skin sensitizers. HMOX1 is often referred to as typical gene regulated by nuclear factor erythroid 2-related factor 2 (Nrf2), however, it is also regulated by other DNA-binding factors, including BTB and CNC homolog 1 (Bach1). The KeratinoSens™ assay is the first validated in vitro assay for sensitizers that measures gene induction. It is based on luciferase expression regulated by the antioxidant response element (ARE) of the aldoketoreductase 1C2 (AKR1C2) gene. Luciferase upregulation is dependent on Nrf2, while HMOX1 upregulation is only partially Nrf2-dependent. Thus, sensitizer-dependent activationmore » of HMOX1 may integrate multiple signals thereby providing additional information. We constructed reporter cell lines containing the full HMOX1 regulatory region or the HMOX1-ARE sequence and compared them with the construct containing the AKR1C2-ARE sequence. Induction of the AKR1C2-ARE depends on Nrf2, but not on the repressor Bach1. Results obtained with HMOX1-ARE and the full HMOX1 promoter indicate that, within the HMOX1 promoter, the HMOX1-ARE is sufficient to explain the induction by sensitizers and that (i) inhibiting Bach1 leads to strong basal expression, (ii) fold-induction by sensitizers above this level is reduced in the absence of Bach1 and (iii) these constructs are less dependent on Nrf2 as compared to the AKR1C2-ARE. Nevertheless, congruent dose response curves for luciferase activity were obtained with all constructs. Thus, while sensitizer-induced HMOX1 activation is dependent on Nrf2 and Bach1, all constructs give identical information for the in vitro prediction of the sensitization potential. - Highlights: • HMOX1 is a key genetic marker up-regulated by skin sensitizers. • HMOX1-, but not AKR1C2-upregulation, is dependent on both Nrf2 and Bach1. • AKR1C2 and HMOX1-dependent reporter constructs yield congruent dose response curves. �
Johannes Kepler and his contribution to Applied Mathematics

NASA Astrophysics Data System (ADS)

Pichler, Franz

The worldwide renown of Johannes Kepler is based above all on his contribution to astronomy. The 3 Kepler's Laws relating to the planets are well known and will ensure that his name is remembered by future generations. Besides his astronomical work, Kepler also made important contributions in the fields of theology, physics, phylosophy and mathematics. The actual paper discusses the advances by Kepler in the application of mathematics to the solution of "real life problems". The author made a concise account of some of the disciples by Kepler: Klug, Wieleitner, Caspar, Hammer, paying particular attention to works published by Kepler while he was living in Linz (1612-1628). The Kepler's contribution to applied mathematics is an example supremely worthy of emulation, the author concludes.

Apart from being a major pioneer of modern psychiatry, Johann Christian August Heinroth (1773 - 1843) is foremost famous as the first academic teacher, professor of this subject at Leipzig University. Despite his theoretical concepts being thoroughly investigated by medical historians, the fact that his scientific work also brought him in contact with Weimar poet and scientist Johann Wolfgang von Goethe (1749 - 1832) has up to now not been acknowledged. This paper analyses for the first time the manifold points of contact between the two geniuses. Starting off with a retrospective on Goethe's relationship towards psychiatry in his day, this paper investigates the mutual interconnections and influences between the two. This is achieved by an analysis of yet unknown primary sources as well as Goethe's literary and scientific works. A main emphasis is also placed on Heinroth's Textbook of Anthropology of 1822 in which the psychiatrist laid out his understanding of 'relational thinking' (gegenständliches Denken), a key concept for both. This theory developed from Heinroth's dealing with Goethe's concept of "anschauung" and was to gain major importance not only for his way of gaining knowledge in general but also for his psychiatric concept. Goethe's influence on Heinroth is particularly revealed in the latter's holistic views on mental illnesses. Heinroth's visit to Goethe on 15 September 1827 can be earmarked as a sign of their mutual esteem.

High-alpine environments are strongly affected by glacier retreat since the Little Ice Age (LIA). Due to ongoing climate change the hydrology of proglacial rivers is also influenced. It is expected that the growing proportions of snow melt and rainfall events will change runoff characteristics of proglacial rivers. Additionally, the importance of paraglacial sediment sources in recently deglaciating glacier forefields is increasing, while the role of glacial erosion is declining. Thus complex environmental conditions leading to a complex pattern of fluvial sediment transport in partly glaciated catchments of the European Alps. Under the umbrella of the joint PROSA-project the fluvial sediment transport of the river Riffler Bach (Kaunertal, Tyrol, Austria) was studied in 3 consecutive ablation seasons in order to quantify sediment yields. In June 2012 a probe for water level and an automatic water sampler (AWS) were installed at the outlet of the catchment (20km2). In order to calculate annual stage-discharge-relations by the rating-curve approach, discharge (Q) was repeatedly measured with current meters and by salt dilution. Concurrent to the discharge measurements bed load was collected using a portable Helley-Smith sampler. Bed load samples were weighted and sieved in the laboratory to gain annual bed load rating curves and grain size distributions. In total 564 (2012: 154, 2013: 209, 2014: 201) water samples were collected and subsequently filtered to quantify suspended sediment concentrations (SSC). Q-SSC-relations were calculated for single flood events due to the high variability of suspended sediment transport. The results show a high inter- and intra-annual variability of solid fluvial sediment transport, which can be explained by the characteristics of suspended sediment transport. Only 13 of 22 event-based Q-SSC-relations show causal dependency. In 2012, during a period with multiple pluvial-induced peak discharges most sediment was transported. On the

Johannes Häringshauser (1603-1941) was born in Vienna and graduated at Padua in the faculty of medicine in 1626. He became a Hofmedicus at the court and in the field of the Thirty Years War in 1627-1630 and then a Viertelmedicus at Mistelbach in Niederoesterreich in 1630 until 1641. His purchase of books had initially concentrated on medical topics but from 1636 to 1640 he bought some ten books on astronomy, including two by Johannes Kepler and one by Michael Mästlin, Kepler's tutor at Tübingen. The fact that he acquired the books by Mästlin and Kepler so soon after Galileo's trial shows him to have been a courageous independently minded thinker with wide ranging professional and intellectual interests. In his professional medical activities he sought to balance the medical practises of Galen and Paracelsus, and in his astronomy hobby he investigated the the new arguments of Mästlin, Kepler, and Galileo.

The term geometrical–optical illusions was coined by Johann Joseph Oppel (1815–1894) in 1855 in order to distinguish spatial distortions of size and orientation from the broader illusions of the senses. We present a translation of Oppel’s article and a commentary on the material described in it. Oppel did much more than give a name to a class of visual spatial distortions. He examined a variety of figures and phenomena that were precursors of later, named illusions, and attempted to quantify and interpret them. PMID:28694957

Background and Objectives The nutritional status and hospital feeding practices of surgical patients in Vietnam are not well documented. Based on a cross-sectional study at Bach Mai Hospital (BMH), the prevalence of malnutrition was found to be 33% in the surgical ward using a body mass index (BMI<18.5 kg/m2. We conducted an observational study over a three month period to evaluate the feeding practices in the gastrointestinal (GI) surgery ward at Bach Mai Hospital (BMH) in Hanoi, Vietnam. Methods and Study Design Investigators from the U.S. and the Vietnamese National Institute of Nutrition (NIN) enrolled 72 subjects admitted for elective GI surgery in an observational study at BMH. Baseline anthropometrics and changes over time, body mass index (BMI), Subjective Global Assessment (SGA) and daily kcal and protein intake from oral diet, tube feeding, and parenteral nutrition (PN) from admission until discharge were documented. Results A total of 50% of subjects scored a B or C on the SGA; 48% of subjects had a BMI<18.5, while mean mid upper arm circumference was in the low-normal range (24±4 cm). Nearly all patients (98%) were given PN postoperatively, with oral feeding starting on an average of postoperative day 4. Only one patient was tube fed. Mean daily total calorie intake was 15 kcal/kg/day and protein intake was 0.61 g/kg/day during hospitalization. Micronutrient supplementation was minimal in subjects receiving PN. Conclusions Hospital malnutrition in surgical patients in Vietnam is a significant problem, peri-operative feeding appears suboptimal and use of early postoperative PN was routine. PMID:27440685

The first hydraulic fracturing of wells in Vietnam were successfully performed Offshore in the Bach Ho (White Tiger) Oil Field. Near-tip-screenouts rather than tip-screenout treatments were performed. The goal of the project was to improve production from existing wells rather than drill new wells and reduce the cost per barrel produced. This case study involves wells with multiple perforated zones completed in the Oligocene sandstone. Zones were selectively fractured in order to optimize production. A detailed description candidate selection, design, execution and evaluation processes are presented. The Bach Ho field has been producing for 8 years but not at itsmore » potential due to various reasons including drilling and completion fluid damage. Although acidizing was an option for damage removal, hydraulic fracturing was selected as a way to bypass near-wellbore damage and generate a negative skin. Production simulators were used to quantify post-frac production. Due to suspected high closure stress, high strength proppant was selected and ramped in a high temperature fracturing fluid. Calibration treatments were conducted on several wells to quantify fluid leak-off, fracture height and Young`s modulus. Based on the results of the calibration treatment, fracture designs were modified. As predicted by computer simulation, near-tip-screenouts occurred as planned. The treatments were performed using a work boat with skid pumping/blending equipment, a computer monitoring/operation center and a laboratory. Strict QC procedures were followed to ensure the quality of all products. Post-frac well tests results and production data are presented. Overall, the fracturing campaign was very successful with wells showing negative skins and up to a five fold increase of production in agreement with systems analysis predictions.« less
A statistical physics view of pitch fluctuations in the classical music from Bach to Chopin: evidence for scaling.

Because classical music has greatly affected our life and culture in its long history, it has attracted extensive attention from researchers to understand laws behind it. Based on statistical physics, here we use a different method to investigate classical music, namely, by analyzing cumulative distribution functions (CDFs) and autocorrelation functions of pitch fluctuations in compositions. We analyze 1,876 compositions of five representative classical music composers across 164 years from Bach, to Mozart, to Beethoven, to Mendelsohn, and to Chopin. We report that the biggest pitch fluctuations of a composer gradually increase as time evolves from Bach time to Mendelsohn/Chopin time. In particular, for the compositions of a composer, the positive and negative tails of a CDF of pitch fluctuations are distributed not only in power laws (with the scale-free property), but also in symmetry (namely, the probability of a treble following a bass and that of a bass following a treble are basically the same for each composer). The power-law exponent decreases as time elapses. Further, we also calculate the autocorrelation function of the pitch fluctuation. The autocorrelation function shows a power-law distribution for each composer. Especially, the power-law exponents vary with the composers, indicating their different levels of long-range correlation of notes. This work not only suggests a way to understand and develop music from a viewpoint of statistical physics, but also enriches the realm of traditional statistical physics by analyzing music.

Johannes Kepler and the Supernova of 1604

2006-08-01

The brilliant luminary that first appeared in October 1604 was considered by many contemporaries to be a new star of unrivalled magnitude. Shining forth near the historic conjunction of Mars, Jupiter and Saturn, the new star held important implications for several areas of interest, notably astrology, astronomy, chronology and theology. Addressing all of these areas in his comprehensive book, De stella nova (1606), Johannes Kepler (1571-1630) studied the new star extensively under the aegis of Holy Roman Emperor Rudolf II (1552-1612) in Prague. The focus of the following presentation is Kepler's theory of the new star's origins in the celestial ether. Describing the heavens poetically as a fertile expanse of "liquid fields", Kepler suggested that the new star sprung from the celestial ether much like the numerous living beings in the sublunary realm which were spontaneously generated from the Earth. As evidence for his claim, Kepler pointed to the conspicuous mathematical patterns similarly observed in earthly and celestial entities. Kepler's efficient cause for this explanation, known as the animate faculty, accounted for both the generation and form of new phenomena in the celestial and terrestrial realms. The new star of 1604 proved to be no exception.

Johannes Kepler (1571-1630) is remembered as one of the greatest medieval astronomers in the tradition of Copernicus and Galileo, a man who made major contributions to physics, astronomy, and mathematics. Born in Germany and trained as a theologian, Kepler did not hesitate to challenge church doctrine by supporting the iconoclastic theory of a Sun-centered solar system. As Imperial Mathematician to the Holy Roman Emperor, he conducted careful observations of the night sky, which led to his discovery of the three Laws of Planetary Motion and the orbit of Mars. He also devised the Rudolphine Tables on planetary movements, and made key improvements to the telescope. Voelkel vividly describes the scientific achievements, providing enough background in physics and trigonometry so even beginners can enjoy this book. The author also gives us a captivating account of Kepler's tumultuous life, plagued by misery, disease, and fervent religious prosecution by the Catholic Church.Oxford Portraits in Science is an ongoing series of scientific biographies for young adults. Written by top scholars and writers, each biography examines the personality of its subject as well as the thought process leading to his or her discoveries.

Hereditary breast cancer and the BRCA1-associated FANCJ/BACH1/BRIP1

Cantor, Sharon B; Guillemette, Shawna

2011-01-01

It is clear that FANCJ, also known as BACH1 or BRIP1, is an essential tumor suppressor gene based on the identification of clinically relevant mutations not only in breast cancer, but also the childhood cancer syndrome, Fanconi anemia. This conclusion is further supported by the direct and functional interaction between FANCJ and the hereditary breast cancer-associated gene product BRCA1. In the absence of the FANCJ DNA helicase or its interaction with BRCA1, cells have defects in several aspects of the DNA damage response. In particular, the BRCA1–FANCJ interaction is essential for promoting error-free repair, checkpoint control and for limiting DNA damage tolerance. As the number of FANCJ clinical mutations and affected patients accumulate, it will be critical to understand whether the associated tumors resemble BRCA-associated tumors. If so, FANCJ patients could also benefit from new therapies that selectively sensitize DNA repair-defective tumors and spare healthy cells. In this article, we summarize the breast cancer-associated FANCJ mutations and discuss functional outcomes for DNA repair and tumor suppression. PMID:21345144

The impact of Johann Gottfried von Herder on the broad spectrum of the history of ideas can hardly be estimated by separate categories derived from individual disciplines. It transcends the spheres of philosophy, theology, historiography and even medical anthropology--also because Herder, unlike many of his contemporary philosophers and hommes de lettres, was particularly interested in the neurophysiological and -anatomical investigations of his time. Herder's universal interest in human learning is reflected in numerous personal contacts to contemporary academic scholars and natural scientists, such as the Swiss theologian Johann Caspar Lavater, whose physiognomic doctrine mapped out a comprehensive research programme on character analysis, or the Mainz anatomist Samuel Thomas von Soemmering. Herder tightly received the latter's assumption about the interplay between the human soul and the anatomy of the brain. In this article, it shall be demonstrated that Herder's neurophilosophy was primarily influenced by a "pandynamic assumption of nature" and that it designated the brain centrally as a "working tool of God"--right between the human faculties of rationality, feeling and bodily development. The attractiveness of this concept to both basic brain research and clinical neurology was a result of his anthropological approach which combined latest developments in the natural sciences with a central perspective on the human sciences.
The Discovery of Gravitational Repulsion by Johannes Droste

NASA Astrophysics Data System (ADS)

McGruder, Charles Hosewell; VanDerMeer, B. Wieb

2018-01-01

In 1687 Newton published his universal law of gravitation, which states that the gravitational force is always attractive. This law is based on our terrestrial experience with slowly moving bodies (v << c). In 1915 Einstein completed his theory of general relativity (also referred to as Einstein’s Theory of Gravitation), which is valid not just for slowly moving bodies but also for those with relativistic velocities. In 1916 Johannes Droste submitted a PhD thesis on general relativity to his advisor, H.A. Lorentz. In it he calculated the motion of a particle in what he called a “single center” and today we call the Schwarzschild field and found that highly relativistic particles experience gravitational repulsion. Thus, his thesis written in Dutch and never before translated contains the discovery of gravitational repulsion. Because of its historical importance we translate the entire section of his thesis containing the discovery of gravitational repulsion. We also translate his thesis in the hope of clearing up a major historical misconception. Namely, that David Hilbert in 1917 discovered gravitational repulsion. In fact, Hilbert rediscovered it, apparently completely independent of Droste’s work. Finally we note that one of the biggest mysteries of astrophysics is the question of how highly energetic particles in relativistic jets and cosmic rays are accelerated. It has been suggested that gravitational repulsion is the mechanism responsible for these phenomena. An historical understanding of gravitational repulsion is therefore pertinent.
Identifying the stars on Johann Bayer's Chart of the South Polar Sky

2014-04-01

The first chart of the stars in the region around the south celestial pole was published in 1603 by Johann Bayer (1572-1625) as part of his monumental star atlas called Uranometria. This south polar chart depicted 12 entirely new constellations that had been created only a few years earlier from stars observed during the first Dutch expedition to the East Indies in 1595-97. Bayer's chart plotted 121 stars in the 12 newly invented constellations. Five more stars formed a southern extension of the existing constellation Eridanus, while another twelve stars were left 'unformed', i.e. unattached to any constellation. Whereas Bayer famously applied Greek or Roman letters to the stars in the 48 Ptolemaic constellations, he left the stars in the newly invented constellations unlabelled. This paper attempts to identify the stars plotted on Bayer's chart. It also discusses the source of Bayer's data and the origin of the 12 new southern constellations.

A cardiac catheterization laboratory can be a frightening environment and music can be a supportive source of environmental sound that stimulates and maintains relaxation. However, the results of studies are conflicting in this regard. The aim of this study was to investigate the effect of music therapy on patients' anxiety and hemodynamic parameters during percutaneous transluminal coronary angioplasty. This was a randomized controlled trial, conducted in the Catheterization Laboratory Unit of Baqiyatallah Hospital, in Tehran, Iran. A sample of 64 patients, who were planned to undergo coronary angioplasty, was recruited. Patients were randomly allocated to either the control or the experimental groups. In the experimental group, patients received a 20 to 40-minute music therapy intervention, consisting of light instrumental music albums by Johann Sebastian Bach and Mariko Makino. Patients in the control group received the routine care of the study setting, which consisted of no music therapy intervention. Study data were collected by a demographic questionnaire, the Spielberger's State Anxiety Inventory, and a data sheet for documenting hemodynamic parameters. Chi-square, independent-samples t tests, paired-samples t-test and repeated measures analysis of variance were used to analyze the data. Before the intervention, the study groups did not differ significantly in terms of anxiety level and hemodynamic parameters. Moreover, the differences between the two groups, regarding hemodynamic parameters, were not significant after the intervention (P > 0.05). However, the level of post-intervention anxiety in the experimental group was significantly lower than the control group (32.06 ± 8.57 and 38.97 ± 12.77, respectively; P = 0.014). Compared with the baseline readings, the level of anxiety in the control group did not change significantly after the study (41.91 ± 9.88 vs. 38.97 ± 12.77; P = 0.101); however, in the experimental group, the level of post

The German writerJean Paul (Johann Paul Friedrich Richter, 1763-1825) and his friendJohann Bernhard Hermann (1761-1790) became acquainted with the thoughts of late Enlightenment at the University of Leipzig. They particularly appreciated the anthropology of Ernst Platner, who taught philosophy and aesthetics as well as medicine. Their confidential correspondence contains reflections on their respective situation and well being. Both write about feeling ill and label their illness "hypochondria". In the course of the correspondence Jean Paul's understanding of hypochondria evolves from an illness of the entrails as he follows Hermann, who supports the modern concept of hypochondria as an illness of the nerves. Two important themes from this correspondence recur in Jean Paul's novels and tales: firstly, his way of expressing comfort is related to his aesthetics, and secondly, the satirical way of portraying at least certain aspects of illness as imaginary reappears in his first successful novel "The Invisible Lodge" (1793).
The oxygenase-peroxidase theory of Bach and Chodat and its modern equivalents: change and permanence in scientific thinking as shown by our understanding of the roles of water, peroxide, and oxygen in the functioning of redox enzymes.

Alexander Bach was both revolutionary politician and biochemist. His earliest significant publication, "Tsar-golod" ("The Tsar of Hunger"), introduced Marxist thought to Russian workers. In exile for 30 years, he moved to study the dialectic of the oxidases. When his theory of oxidases as combinations of oxygenases and peroxidases was developed (circa 1900) the enzyme concept was not fully formulated, and the enzyme/substrate distinction not yet made. Peroxides however were then and remain now significant intermediates, when either free or bound, in oxidase catalyses. The aerobic dehydrogenase/peroxidase/catalase coupled systems which were studied slightly later clarified the Bach model and briefly became an oxidase paradigm. Identification of peroxidase as a metalloprotein, a key step in understanding oxidase and peroxidase mechanisms, postdated Bach's major work. Currently we recognize catalytic organic peroxides in flavoprotein oxygenases; such organic peroxides are also involved in lipid oxidation and tryptophan radical decay. But most physiologically important peroxides are now known to be bound to transition metals (either Fe or Cu) and formed both directly and indirectly (from oxygen). The typical stable metalloprotein peroxide product is the ferryl state. When both peroxide oxidizing equivalents are retained the second equivalent is held as a protein or porphyrin radical. True metal peroxide complexes are unstable. But often water molecules mark the spot where the original peroxide decayed. The cytochrome c oxidase Fe-Cu center can react with either peroxide or oxygen to form the intermediate higher oxidation states P and F. In its resting state water molecules and hydroxyl ions can be seen marking the original location of the oxygen or peroxide molecule.

Bach Is the Father of Harmony: Revealed by a 1/f Fluctuation Analysis across Musical Genres.

Harmony is a fundamental attribute of music. Close connections exist between music and mathematics since both pursue harmony and unity. In music, the consonance of notes played simultaneously partly determines our perception of harmony; associates with aesthetic responses; and influences the emotion expression. The consonance could be considered as a window to understand and analyze harmony. Here for the first time we used a 1/f fluctuation analysis to investigate whether the consonance fluctuation structure in music with a wide range of composers and genres followed the scale free pattern that has been found for pitch, melody, rhythm, human body movements, brain activity, natural images and geographical features. We then used a network graph approach to investigate which composers were the most influential both within and across genres. Our results showed that patterns of consonance in music did follow scale-free characteristics, suggesting that this feature is a universally evolved one in both music and the living world. Furthermore, our network analysis revealed that Bach's harmony patterns were having the most influence on those used by other composers, followed closely by Mozart.
A Simultaneous Discovery: The Case of Johannes Stark and Antonino Lo Surdo

In 1913 the German physicist Johannes Stark (1874 1957) and the Italian physicist Antonino Lo Surdo (1880 1949)discovered virtually simultaneously and independently that hydrogen spectral lines are split into components by an external electric field. Both of their discoveries ensued from studies on the same phenomenon, the Doppler effect in canal rays, but they arose in different theoretical contexts. Stark had been working within the context of the emerging quantum theory, following a research program aimed at studying the effect of an electric field on spectral lines. Lo Surdo had been working within the context of the classical theory, and his was an accidental discovery. Both discoveries, however, played important roles in the history of physics: Stark’s discovery contributed to the establishment of both the old and the new quantum theories; Lo Surdo’s discovery led Antonio Garbasso (1871 1933)to introduce research on the quantum theory into Italian physics. Ironically, soon after their discoveries, both Stark and Lo Surdo rejected developments in modern physics and allied themselves with the political and racial programs of Hitler and Mussolini.

A newly designed vacuum Johann spectrometer with a large focusing analyzer crystal for inelastic x-ray scattering and high resolution fluorescence spectroscopy has been installed at the DORIS III storage ring. Spherically bent crystals with a maximum diameter of 125 mm, and cylindrically bent crystals are employed as dispersive optical elements. Standard radius of curvature of the crystals is 1000 mm, however, the design of the mechanical components also facilitates measurements with smaller and larger bending radii. Up to four crystals are mounted on a revolving crystal changer which enables crystal changes without breaking the vacuum. The spectrometer works at fixedmore » Bragg angle. It is preferably designed for the measurements in non-scanning mode with a broad beam spot, and offers a large flexibility to set the sample to the optimum position inside the Rowland circle. A deep depletion CCD camera is employed as a position sensitive detector to collect the energy-analyzed photons on the circumference of the Rowland circle. The vacuum in the spectrometer tank is typically 10-6 mbar. The sample chamber is separated from the tank either by 25 {mu}m thick Kapton windows, which allows samples to be measured under ambient conditions, or by two gate valves. The spectrometer is currently installed at wiggler beamline W1 whose working range is 4-10.5 keV with typical flux at the sample of 5x1010photons/s/mm2. The capabilities of the spectrometer are illustrated by resonant inelastic experiments on 3d transition metals and rare earth compounds, and by chemical shift measurements on chromium compounds.« less

This work relates the reception of schools, started on August 2012, in the astronomic laboratory of the "Planetário e Teatro Digital Johannes Kepler", located in the "Sabina - Escola Parque do Conhecimento" in Santo André, São Paulo. The idealization of this project, authorship of Marcos Calil, PhD, consists in four apprenticeship environments disposed around the planetary dome. They make reference to the System Sun - Earth - Moon (Tellurium), Solar System, Astronautic and Stars. On Tuesdays and Wednesdays the astronomic laboratory is used by Santo André municipal schools for focused lessons, being possible on Thursdays scheduling for private and public schools. On weekends and holidays is opened for the visitors. Since the inauguration to the beginning of activities with students, the monitor team was guided and trained on contents of Astronomy and Aeronautic to execute the schools service. This is done in four stages, which are: reception, course trough the astronomic laboratory, dome session and activities closure. During the reception the acquaintance rules are passed on for a better visit. Before starting the course the monitors do a survey about the previous knowledge of the students. On the astronomic laboratory resources of the environment are used to explain the contents of Astronomy and Astronautic, always considering the age group and the curriculum developed in classroom. After the course the students watch a planetary session supporting the contents seen on the astronomic laboratory. At the end a feedback is done with the students about the subject discussed. During the visit the teachers fulfill an evaluation about the place and the service. From August 2012 to November 2012 were attended between municipal, public and private schools. From the 4932 students attended, 92% belonged to the municipal network, 5% to the private network and 3% to the public network. From the 189 evaluations done by the teachers, 97.8% were satisfied, 2.1% partially

The rediscovery of a missing autograph of Johannes Kepler - a dedication letter presenting his "New Astronomy" to the elector of Saxony - was possible through a series of fortunate coincidences. Kepler's most important work "Astronomia Nova", in which he proclaimed the first two planetary laws, has been published at the end of 1609. According to the Latin dedication to emperor Rudolf II., Kepler compares the long period of calculations and observations as a crusade against the planet Mars. Finally he succeeds in defeating him, now he supports his opponent to find a new home. The letter is an extraordinary document of Kepler's ingenious and humorous language, it also proofs the relationship to Dresden and the Saxon court.

Mortimer Frank (1874-1919) was an ophthalmologist in Chicago, Illinois. He published a number of papers on the history of medicine, and was secretary of the Chicago Society of the History of Medicine and editor of their Bulletin. His major contribution to the history of medicine relates to the history of anatomical illustration. The classic book on that subject had been published in 1852 in German by the physician and historian, Johann Ludwig Choulant (1791-1861). However, by Frank's time this text was both out dated and out of print. Frank took on the tremendous project of translating Choulant's German text into English as History and Bibliography of Anatomic Illustration in Its Relation to Anatomic Science and The Graphic Arts. He improved Choulant's text with the results of his and other scholars' research, greatly enlarging the text. Frank supplemented the original book with a biography of Choulant, essays on anatomists not considered in the original text, and an essay on the history of anatomical illustration prior to those authors discussed by Choulant. This book, now referred to as Choulant/Frank, has been reprinted several times, and is still useful as a reference in this field, though some of its research is now dated.

Epoxygenase activity and synthesis of epoxyeicosatrienoic acids (EETs) have emerged as important modulators of obesity and diabetes. We examined the effect of the EET-agonist 12-(3-hexylureido)dodec-8(2) enoic acid on mesenchymal stem cell (MSC) derived adipocytes proliferation and differentiation. MSCs expressed substantial levels of EETs and inhibition of soluble epoxide hydrolase (sEH) increased the level of EETs and decreased adipogenesis. EET agonist treatment increased HO-1 expression by inhibiting a negative regulator of HO-1 expression, Bach-1. EET treatment also increased βcatenin and pACC levels while decreasing PPARγ C/EBPα and fatty acid synthase levels. These changes were manifested by a decrease in the number of large inflammatory adipocytes, TNFα, IFNγ and IL-1α, but an increase in small adipocytes and in adiponectin levels. In summary, EET agonist treatment inhibits adipogenesis and decreases the levels of inflammatory cytokines suggesting the potential action of EETs as intracellular lipid signaling modulators of adipogenesis and adiponectin.

Johann Wilhelm Hittorf and the material culture of nineteenth-century gas discharge research.

PubMed

Müller, Falk

2011-06-01

In the second half of the nineteenth century, gas discharge research was transformed from a playful and fragmented field into a new branch of physical science and technology. From the 1850s onwards, several technical innovations-powerful high-voltage supplies, the enhancement of glass-blowing skills, or the introduction of mercury air-pumps- allowed for a major extension of experimental practices and expansion of the phenomenological field. Gas discharge tubes served as containers in which resources from various disciplinary contexts could be brought together; along with the experimental apparatus built around them the tubes developed into increasingly complex interfaces mediating between the human senses and the micro-world. The focus of the following paper will be on the physicist and chemist Johann Wilhelm Hittorf (1824-1914), his educational background and his attempts to understand gaseous conduction as a process of interaction between electrical energy and matter. Hittorf started a long-term project in gas discharge research in the early 1860s. In his research he tried to combine a morphological exploration of gas discharge phenomena-aiming at the experimental production of a coherent phenomenological manifold--with the definition and precise measurements of physical properties.

Johannes Kepler's manuscripts which remained after his death suffered a troubled fate. It was not possible to collect them in Germany and to work with them systematically, because their importance was strikingly underestimated. Only at the beginning of the 18th century U. Junius in Leipzig tried unsuccessfully to collect and to publish the most important manuscripts. Afterwards M.G. Hansch took up this plan and pursued it until the end of his life. However, the only result was one volume with unpublished letters which appeared in 1718. The hoped-for collected works could not be realized. These events are described in detail, especially the efforts of Junius and Hansch as well as the opposition which eventually lead to a failure of both attempts.

In the seventeenth century it was customary in medicine to copy texts from other authors without citing the source. This practice is illustrated by the diary of Johannes Franc (1649–1725), a physician in the city of Ulm, who handwrote a practice journal in Latin and German Gothic script entering text passages plagiarized as follows: he reproduced them almost word for word in order to pass them off as his own experiences, used them as a model for his prescriptions and as a template for his case histories, and integrated them into his work to support his argumentation. In addition, he summarized texts from various sources, refined them by omitting portions, and incorporated his own experiences for embellishment. These plagiarism techniques and the purpose they served are analyzed and compared to some passages taken from the original texts.

The effect of docosahexaenoic acid (DHA) on heme oxygenase-1 (HO-1) expression in cancer cells has never been characterized. This study examines DHA-induced HO-1 expression in human cancer cell model systems. DHA enhanced HO-1 gene expression in a time- and concentration-dependent manner, with maximal induction at 21 h of treatment. This induction of HO-1 expression was confirmed in vivo using a xenograft nude mouse model fed a fish-oil-enriched diet. The increase in HO-1 gene transcription induced by DHA was significantly attenuated by the antioxidant N-acetyl cysteine, suggesting the involvement of oxidative stress. This was supported by direct measurement of lipid peroxide levels after DHA treatment. Using a human HO-1 gene promoter reporter construct, we identified two antioxidant response elements (AREs) that mediate the DHA-induced increase in HO-1 gene transcription. Knockdown of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) expression compromised the DHA-induced increase in HO-1 gene transcription, indicating the importance of the Nrf2 pathway in this event. However, the nuclear protein levels of Nrf2 remained unchanged upon DHA treatment. Further studies demonstrated that DHA reduces nuclear Bach1 protein expression by promoting its degradation and attenuates Bach1 binding to the AREs in the HO-1 gene promoter. In contrast, DHA enhanced Nrf2 binding to the AREs without affecting nuclear Nrf2 expression levels, indicating a new cellular mechanism that mediates DHA's induction of HO-1 gene transcription. To our knowledge, this is the first characterization of DHA-induced HO-1 expression in human malignant cells. Copyright © 2014 Elsevier Inc. All rights reserved.
Idols of the psychologist: Johannes Linschoten and the demise of phenomenological psychology in the Netherlands.

2008-08-01

Before and after World War II, a loose movement within Dutch psychology solidified as a nascent phenomenological psychology. Dutch phenomenological psychologists attempted to generate an understanding of psychology that was based on Husserlian interpretations of phenomenological philosophy. This movement came to a halt in the 1960s, even though it had been exported to North America and elsewhere as "phenomenological psychology." Frequently referred to as the "Utrecht school," most of the activity of the group was centered at Utrecht University. In this article, the authors examine the role played by Johannes Linschoten in both aspects of the development of a phenomenological psychology: its rise in North America and Europe, and its institutional demise. By the time of his early death in 1964, Linschoten had cast considerable doubt on the possibilities of a purely phenomenological psychology. Nonetheless, his own empirical work, especially his 1956 dissertation published in German, can be seen to be a form of empiricism inspired by phenomenology but that clearly distanced itself from the more elitist and esoteric aspects of Dutch phenomenological psychology.

Modular Cullin-RING E3 ubiquitin ligases (CRLs) use substrate binding adaptor proteins to specify target ubiquitylation. Many of the ~200 human CRL adaptor proteins remain poorly studied due to a shortage of efficient methods to identify biologically relevant substrates. Here, we report the development of Parallel Adaptor Capture (PAC) proteomics, and its use to systematically identify candidate targets for the leucine-rich repeat family of F-box proteins (FBXLs) that function with SKP1-CUL1-F-box protein (SCF) E3s. In validation experiments, we identify the unstudied F-box protein FBXL17 as a regulator of the NFR2 oxidative stress pathway. We demonstrate that FBXL17 controls the transcription of the NRF2 target HMOX1 via turnover of the transcriptional repressor BACH1 in the absence or presence of extrinsic oxidative stress. This work identifies a role for SCFFBXL17 in controlling the threshold for NRF2-dependent gene activation and provides a framework for elucidating the functions of CRL adaptor proteins. PMID:24035498

Confronted with the inability to give birth to a child, delivery could be achieved by embryotomy--that was only permitted, when the foetus was dead--or by Caesarean section--where the chance to save mother and child as well was merely theoretical until the end of the 19th century. In two statements of the Theological Faculty of the Sorbonne in Paris embryotomy was absolutely rejected (1648), in nearly all cases of impossible delivery the Caesarean section was required (1733). In 1749 Johannes Stähelin starts a daring attempt to justify embryotomy by application of natural law to the situation of critical childbirth. Keywords of the theological statements are confronted with categories of the natural law in a sophisticated way, nevertheless the basis of Christian confession is maintained. This argumentation in order to justify embryotomy as a lawful method to deliver a woman seemed to be more adequate to the medical sphere than claiming the Caesarean section. The ethical debate continued until the problem was solved by mastering Caesarean section.

Taking Johannes Müller's still little examined school education in then French Koblenz at its starting point, this paper argues that Miiller's pre-academic training in the applied sciences as well as in the old languages--which Müller saw as a basic essential for the philosophically educated naturalist--had a profound impact on the scientific-philosophical views he put forward in his Dissertatio inauguralis physiologica sistens commentarios de phoronomia animalium published in 1822. The Dissertatio was influenced, in particular, by the work of Pierre-Jean-Georges Cabanis (1757-1808) and can be read as a physiological application of French Enlightenment sensualist philosophy. It shows that Müller already at early moment took up decisive impulses from revolutionary France. Also, a traditional mistake is shown to have falsified a fundamental aspect of this earliest work already with lasting effect.

The life and personality of Johann Gregor Mendel (1822-1884), the founder of scientific genetics, are reviewed against the contemporary background of his times. At the end are weighed the benefits for Mendel (as charged by Sir Ronald Fisher) to have documented his results on hand of falsified data. Mendel was born into a humble farm family in the "Kuhländchen", then a predominantly German area of Northern Moravia. On the basis of great gifts Mendel was able to begin higher studies; however, he found himself in serious financial difficulties because of his father's accident and incapacitation. His hardships engendered illness which threatened continuation and completion of his studies until he was afforded the chance of absolving successfully theological studies as an Augustinian monk in the famous chapter of St. Thomas in Altbrünn (Staré Brno). Psychosomatic indisposition made Mendel unfit for practical pastoral duties. Thus, he was directed to teach but without appropriate state certification; an attempt to pass such an examination failed. At that point he was sent to the University of Vienna for a 2-year course of studies, with emphasis on physics and botany, to prepare him for the exam. His scientific and methodologic training enabled him to plan studies of the laws of inheritance, which had begun to interest him already during his theology training, and to choose the appropriate experimental plant. In 1865, after 12 years of systematic investigations on peas, he presented his results in the famous paper "Versuche über Pflanzenhybriden." Three years after his return from Vienna he failed to attain his teaching certification a second time. Only by virtue of his exceptional qualifications did he continue to function as a Supplementary Professor of Physics and Natural History in the two lowest classes of a secondary school. In 1868 he was elected Abbot of his chapter, and freed from teaching duties, was able to pursue his many scientific interests with greater

Among the German pioneers of Western medicine in Japan (8, 12) during the Meiji period (1868-1912), veterinary officer Johannes Ludwig Janson (1849-1914) was one of the most important figures. He arrived in Tokyo in October 1880 and taught at the Veterinary School in Komaba. During his tenure, the school in Komaba was integrated into the School of Agriculture of the Imperial University of Tokyo. Numerous of his graduates occupied high public offices. Among his publications, those about domestic animals and veterinary medicine in Japan deserve special attention. He married a Japanese girl and continued teaching in Komaba until 1902. He found his last resting place in Kagoshima, the native place of his wife. To this day, the Japanese consider Janson the founder of modern veterinary medicine in their country.

Bach1 and Bach2 are evolutionarily related members of the BTB-basic region leucine zipper transcription factor family. We found that Bach2 downregulates cell proliferation of N1E-115 cells and negatively affects their potential to differentiate. Nuclear localization of the cyclin-dependent kinase inhibitor p21 is known to arrest cell cycle progression, and cytoplasmic p21 has been shown to promote neuronal differentiation of N1E-115 cells. We found that ectopic Bach2 causes upregulation of p21 expression in the nucleus and in the cytoplasm in undifferentiated N1E-115 cells. In differentiated cells, Bach2 specifically triggers upregulation of cytoplasmic p21. Our data suggest that Bach2 expression could representmore » a switch during the process of neuronal differentiation. Bach2 is not expressed in neuronal precursor cells. It would have negative effects on proliferation and differentiation of these cells. In differentiated neuronal cells Bach2 expression is upregulated, which could allow Bach2 to function as a gatekeeper of the differentiated status.« less

The instrument is set at the wiggler beamline 6-2 equipped with two liquid nitrogen cooled monochromators - Si(111) and Si(311) - as well as collimating and focusing optics. The spectrometer consists of seven spherically bent crystal analyzers placed on intersecting vertical Rowland circles of 1 m of diameter. The spectrometer is scanned vertically capturing an extended backscattering Bragg angular range (88 Degree-Sign -74 Degree-Sign ) while maintaining all crystals on the Rowland circle trace. The instrument operates in atmosphericmore » pressure by means of a helium bag and when all the seven crystals are used (100 mm of projected diameter each), has a solid angle of about 0.45% of 4{pi} sr. The typical resolving power is in the order of (E/{Delta}E){approx}10 000. The spectrometer's high detection efficiency combined with the beamline 6-2 characteristics permits routine studies of x-ray emission, high energy resolution fluorescence detected x-ray absorption and resonant inelastic x-ray scattering of very diluted samples as well as implementation of demanding in situ environments.« less

The report urges strengthening of public health and global health in Germany and addresses explicitly the Public Health Service (PHS). This indispensable inclusion of the PHS in further strategic planning offers for the first time an opportunity for a comprehensive and sustainable practice/policy transfer on the federal, state and community level, and also a chance for a sustainable network with modern academic public health institutions together with representation of medical specialization in public health at universities, that has been absent so far.

Genetic polymorphisms within a single locus encoding BACH2 are associated with various autoimmune diseases and allergies. In this study, restriction landmark genomic scanning revealed methylation at a NotI site in a CpG island covering the BACH2 promoter in gastric cancer cell lines and primary gastric tumors. Increased methylation of the BACH2 promoter was observed in 52% (43/83) of primary gastric tumors, and BACH2 hypermethylation was significantly associated with decreased gene expression. Treatment with 5-aza-2'-deoxycytidine and/or trichostatin. A restored BACH2 expression in BACH2-silenced gastric cancer cell lines, and knockdown of BACH2 using short hairpin RNA (i.e. RNA interference) increased cell proliferation in gastric cancer cells. Clinicopathologic data showed that decreased BACH2 expression occurred significantly more frequently in intestinal-type (27/44, 61%) compared with diffuse-type (13/50, 26%) gastric cancers (P<0.001). Furthermore, BACH2 promoter methylation paralleled that of previously identified targets, such as LRRC3B, LIMS2, PRKD1 and POPDC3, in a given set of gastric tumors. We propose that concerted methylation in many promoters plays a role in accelerating gastric tumor formation and that methylated promoter loci may be targets for therapeutic treatment, such as the recently introduced technique of epigenetic editing.

Johann Peter Griess FRS (1829–88): Victorian brewer and synthetic dye chemist

PubMed Central

Yates, Edwin; Yates, Andrew

2016-01-01

The German organic chemist Johann Peter Griess (1829–88), who first developed the diazotization of aryl amines (the key reaction in the synthesis of the azo dyes), and a major figure in the formation of the modern dye industry, worked for more than a quarter of a century at the brewery of Samuel Allsopp and Sons in Burton upon Trent, which, owing to the presence of several notable figures and an increase in the scientific approach to brewing, became a significant centre of scientific enquiry in the 1870s and 1880s. Unlike the other Burton brewing chemists, Griess paralleled his work at the brewery with significant contributions to the chemistry of synthetic dyes, managing to keep the two activities separate—to the extent that some of his inventions in dye chemistry were filed as patents on behalf of the German dye company BASF, without the involvement of Allsopp's. This seemingly unlikely situation can be explained partly by the very different attitudes to patent protection in Britain and in Germany combined with an apparent indifference to the significant business opportunity that the presence of a leading dye chemist presented to Allsopp's. Although his work for the brewery remained largely proprietary, Griess's discoveries in dye chemistry were exploited by the German dye industry, which quickly outpaced its British counterpart. One less well-known connection between brewing and synthetic dyes, and one that may further explain Allsopp's attitude, is the use of synthetic dyes in identifying microorganisms—the perennial preoccupation of brewers seeking to maintain yield and quality. Developments of Griess's original work continue to be applied to many areas of science and technology.

Diffuse large B-cell lymphoma (DLBCL) is the most common B-cell lymphoma subtype, and the Epstein-Barr virus (EBV)-positive subtype of DLBCL is known to show a more aggressive clinical behavior than the EBV-negative one. BTB and CNC homology 2 (BACH2) has been highlighted as a tumor suppressor in hematopoietic malignancies; however, the role of BACH2 in EBV-positive DLBCL is unclear. In the present study, BACH2 expression and its significance were studied in 23 EBV-positive and 43 EBV-negative patient samples. Immunohistochemistry revealed BACH2 downregulation in EBV-positive cases (P < 0.0001), although biallelic deletion of BACH2 was not detected by FISH. Next, we analyzed the contribution of BACH2 negativity to aggressiveness in EBV-positive B-cell lymphomas using FL-18 (EBV-negative) and FL-18-EB cells (FL-18 sister cell line, EBV-positive). In BACH2-transfected FL-18-EB cells, downregulation of phosphorylated transforming growth factor-β-activated kinase 1 (pTAK1) and suppression in p65 nuclear fractions were observed by Western blot analysis contrary to non-transfected FL-18-EB cells. In patient samples, pTAK1 expression and significant nuclear p65, p50, and p52 localization were detected immunohistochemically in BACH2-negative DLBCL (P < 0.0001, P = 0.006, and P = 0.001, respectively), suggesting that BACH2 downregulation contributes to constitutive activation of the nuclear factor-κB pathway through TAK1 phosphorylation in BACH2-negative DLBCL (most EBV-positive cases). Although further molecular and pathological studies are warranted to clarify the detailed mechanisms, downregulation of BACH2 may contribute to constitutive activation of the nuclear factor-κB pathway through TAK1 activation. © 2017 The Authors.

Purpose The objective is to estimate the prevalence of symptoms suggestive of Painful Bladder Syndrome (PBS) defined as pain increasing as the bladder fills and/or pain relieved by urination for at least three months and its association with socio-demographics (gender, age, race/ethnicity, and socioeconomic status), lifestyle (smoking, alcohol consumption, physical activity) and psychosocial variables (sexual, physical, emotional abuse experienced as a child or as an adult, worry, trouble paying for basics, depression). Materials and Methods The data used come from the Boston Area Community Health (BACH) survey, an epidemiologic study of 5506 randomly selected adults aged 30-79 of three race/ethnic groups (Black, Hispanic, White). Results The overall prevalence of symptoms suggestive of PBS is two percent (1.3% in men and 2.6% in women) with increased prevalence in middle aged adults and those of lower socioeconomic status. Symptoms suggestive of PBS are more common in those who have experienced abuse, in those who are worried about someone close to them, and in those who are having trouble paying for basics. This pattern holds even after adjusting for depression. Conclusions PBS is associated with a number of lifestyle and psychosocial correlates. This suggests that the management of patients with PBS (physical symptoms) may benefit from a multi-faceted approach of combining medical and psychological, and cognitive treatment. PMID:18554658

Goethe: A bipolar personality? Periodicity of affective states in Johann Wolfgang von Goethe as reflected by Paul Julius Möbius.

PubMed

Steinberg, Holger; Schönknecht, Peter

2018-01-01

This paper aims to investigate the character and etiological basis of German poet Johann Wolfgang von Goethe's mental disorder. From 1898, German neuropsychiatrist Paul Julius Möbius developed the hypothesis that Goethe's work provided several hints for the notion that the German poet suffered from a distinct bipolar disorder. The paper investigates Möbius's psychopathographic study on Goethe and his hypothesis of a mood periodicity in Goethe against the mirror of modern concepts. Möbius came to the conclusion that Goethe's illness was bipolar in character and became visible at intervals of seven years and lasted for about two years. The majority of Möbius's contemporary psychiatric colleagues (Emil Kraepelin, Max Isserlin, Ernst Kretschmer, Josef Breuer) supported this view which has still not been convincingly challenged. In present-day terms, Möbius's hypothesis can be best mirrored as a subclinical foundation of mood disorder. Furthermore, with his extensive study, Möbius disproved the common notion that Goethe had suffered from an illness as the result of a syphilitic infection.

Throughout his work Johann Christian August Heinroth regarded sin to be the cause of mental illness. The present two-part paper investigates what exactly Heinroth understood by sin. Based on a thorough analysis of his own texts, this study shows that on the one hand Heinroth referred to sin in a Christian-Protestant sense. On the other, however, a moral-ethical code of conduct was also involved. Thus, Heinroth did not regard sin as a singular event, but rather as a life conducted in a wrong way for years or even decades, by which he meant a steady striving towards earthly, bodily satisfaction.

Steinmann, Michael

2013-01-01

Johann Christian Reil's (1759-1813) importance lies in his theoretical approach to medicine. Following Kant in his early work, he attempts to combine medical experience with an underlying conceptual structure. This attempt is directed against both the chaotic empiricism of traditional medicine and speculative theories such as vitalism. The paper starts from his early reflections on the concept of a life force, which he interprets in the way of a non-reductive materialism. In the following, the basic outlines of his Theory of Fever will be shown. The Theory is a systematic attempt at finding a new foundation for diagnosis and therapy on the basis of the concept of fever, which is understood as modification of vital processes. The paper ends with a discussion of his later work, which has remained controversial so far. It shows that the combination of practical empiricism and scientific theory remained rather unstable in this early phase of the development of modern medicine.
Cueing musical emotions: An empirical analysis of 24-piece sets by Bach and Chopin documents parallels with emotional speech.

PubMed

Poon, Matthew; Schutz, Michael

2015-01-01

Acoustic cues such as pitch height and timing are effective at communicating emotion in both music and speech. Numerous experiments altering musical passages have shown that higher and faster melodies generally sound "happier" than lower and slower melodies, findings consistent with corpus analyses of emotional speech. However, equivalent corpus analyses of complex time-varying cues in music are less common, due in part to the challenges of assembling an appropriate corpus. Here, we describe a novel, score-based exploration of the use of pitch height and timing in a set of "balanced" major and minor key compositions. Our analysis included all 24 Preludes and 24 Fugues from Bach's Well-Tempered Clavier (book 1), as well as all 24 of Chopin's Preludes for piano. These three sets are balanced with respect to both modality (major/minor) and key chroma ("A," "B," "C," etc.). Consistent with predictions derived from speech, we found major-key (nominally "happy") pieces to be two semitones higher in pitch height and 29% faster than minor-key (nominally "sad") pieces. This demonstrates that our balanced corpus of major and minor key pieces uses low-level acoustic cues for emotion in a manner consistent with speech. A series of post hoc analyses illustrate interesting trade-offs, with sets featuring greater emphasis on timing distinctions between modalities exhibiting the least pitch distinction, and vice-versa. We discuss these findings in the broader context of speech-music research, as well as recent scholarship exploring the historical evolution of cue use in Western music.

Johann Joachim Winckelmann, German historian of ancient art and archaeologist, was born on 9 December 1717 in Stendal, a town in Saxony-Anhalt. At the age of 50 he was murdered on 8 June 1768 in a Trieste hotel. The voluminous original record of the criminal proceedings against his murderer, Francesco Arcangeli, was presumed lost for about 150 years. A new edition in the wording of the original text appeared in 1964. This long sought historical document gives cause for forensic-historical reflections under consideration of the autopsy protocol about Winckelmann, which is likewise a historical document. A considerable change of paradigm in comparison to current autopsy protocols is observed with regard to the evaluation of injuries and the circumstances of death.

Contemporary suspended sediment yield of a partly glaciated catchment, Riffler Bach (Tyrol, Austria)

2015-04-01

Due to glacier retreat since the LIA (Little Ice Age) proglacial areas in high mountain landscapes are growing. These systems are characterized by a high geomorphological activity, especially in the fluvial subsystem. Despite the long tradition of geomorphological research in the European Alps there is a still a lack of understanding in the interactions between hydrology, sediment sources, sediments sinks and suspended sediment transport. As emphasized by ORWIN ET AL. (2010) those problems can be solved by gathering data in a higher frequency and/or in a higher spatial resolution or density - both leading to a big amount of data. In 2012 a gauging station was installed at the outlet of the partly glaciated catchment of the Riffler Bach (Kaunertal valley, Tyrol). During the ablation seasons in 2012 and 2013 water stage was logged automatically every 15 minutes. In both seasons discharge was measured at different water levels to calculate a stage-discharge relation. Additionally, water samples were taken by an automatic water sampler. Within 16 sampling cycles with sampling frequencies ranging from 1 to 24 hours 389 water samples have been collected. The samples were filtered to calculate the suspended sediment concentration (SSC) of each sample. Furthermore, the climate station Weißsee provided meteorological data at a 15 minute interval. Due to the high variability in suspended sediment transport in proglacial rivers it is impossible to compute a robust annual Q-SSC-relation. Hence, two other approaches were used to calculate the suspended sediment load (SSL) and the suspended sediment yield (SSY): A) Q-SSC-relations for every single sampling cycle (e.g. GEILHAUSEN ET AL. 2013) B) Q-SSC-relations based on classification of dominant runoff-generating processes (e.g. ORWIN AND SMART 2004). The first approach uses commonly operated analysis methods that are well understood. While the hydro-climatic approach is more feasible to explain discharge generation and to

2010-09-01

This paper describes the improvements to be implemented in the Safety console position of the Engineering Support Team(EST) at the Automated Transfer Vehicle(ATV) Control Centre(ATV-CC) for the upcoming ATV Johannes Kepler mission. The ATV missions to the International Space Station are monitored and controlled from the ATV-CC in Toulouse, France. The commanding of ATV is performed by the Vehicle Engineering Team(VET) in the main control room under authority of the Flight Director. The EST performs a monitoring function in a room beside the main control room. One of the EST positions is the Safety console, which is staffed by safety engineers from ESA and the industrial prime contractor, Astrium. The function of the Safety console is to check whether the hazard controls are available throughout the mission as required by the Hazard Reports approved by the ISS Safety Review Panel. Safety console preparation activities were limited prior to the first ATV mission due to schedule constraints, and the safety engineers involved have been working to improve the readiness for ATV 2. The following steps have been taken or are in process, and will be described in this paper: • review of the implementation of Operations Control Agreement Documents(OCADs) that record the way operational hazard controls are performed to meet the needs of the Hazard Reports(typically in Flight Rules and Crew Procedures), • crosscheck of operational control needs and implementations with respect to ATV's first flight observations and post flight evaluations, with a view to identifying additional, obsolete or revised operational hazard controls, • participation in the Flight Rule review and update process carried out between missions, • participation in the assessment of anomalies observed during the first ATV mission, to ensure that any impacts are addressed in the ATV 2 safety documentation, • preparation of a Safety console handbook to provide lists of important safety aspects to be

2014-01-01

This article discusses a largely overlooked aspect of the last work by Johannes Broscius (1585 - 1652), his Apologia pro Aristotele et Euclide contra Petrum Ramum et alios of 1652. While the past researchers focused their attention on the evaluation of Broscius's contribution to mathematics, geometry in particular, they ignored the socio-scientific aspect of his work, that is the way Peter Ramus and his followers have been presented and how did the dark legend of Ramus have been thus revived at the Central-European university in the middle of 17th century. I am showing types of rhetorical arguments employed by Broscius and analyse the way he portrayed Ramus and depicted events related to the reception of Ramism at the Academy of Cracow. The article is followed by an appendix which contains a critical edition of excerpts from the manuscript rough draft of Apologia which has been preserved until nowadays (Jagiellonian Library MS. 3205 I). In the apparatus I identify the references and show how Broscius rewrote and rearranged the original paragraphs of his anti-Ramist work.

Objectives The objectives of this study were: 1) to determine whether there is an association between C-reactive protein (CRP) levels and lower urinary tract symptoms (LUTS) as assessed by the American Urological Association Symptom Index (AUA-SI) among both men and women, 2) to determine the association of CRP levels with individual urologic symptoms comprising the AUA-SI among both men and women. Methods The Boston Area Community Health (BACH) Survey used a multistage stratified design to recruit a random sample of 5,502 adults age 30–79. Blood samples were obtained on 3,752 participants. Analyses were conducted on 1,898 men and 1,854 women with complete data on C-Reactive Protein (CRP) levels. Overall LUTS was defined as an AUA-SI≥8 (moderate to severe LUTS). Urologic symptoms comprising the AUA-SI were included in the analysis as reports of fairly often to almost always vs. non/rarely/a few times. Results A statistically significant association was observed between CRP levels and overall LUTS among both men and women. The pattern of associations between individual symptoms and CRP levels varied by gender. Nocturia and straining were associated with higher CRP levels among men, while incomplete emptying and weak stream were associated with higher CRP levels among women. Conclusions This study demonstrates an association between CRP levels and LUTS in both men and women. The dose-response relationship between increased CRP levels and increased odds of LUTS supports the hypothesized role of inflammatory processes in the etiology of LUTS. PMID:19394490

Purpose Racial/ethnic disparities in the incidence of type 2 diabetes (T2DM) are well documented and many researchers have proposed that biogeographical ancestry (BGA) may play a role in these disparities. However, studies examining the role of BGA on T2DM have produced mixed results to date. Therefore, the objective of this research is to quantify the contribution of BGA to racial/ethnic disparities in T2DM incidence controlling for the mediating influences of socioeconomic factors. Methods We analyzed data from the Boston Area Community Health (BACH) Survey, a prospective cohort with approximately equal numbers of Black, Hispanic, and White participants. We used Ancestry Informative Markers to calculate the percentages of West African and Native American ancestry of participants. We used logistic regression with g-computation to analyze the contribution of BGA and socioeconomic factors to racial/ethnic disparities in T2DM incidence. Results We found that socioeconomic factors accounted for 44.7% of the total effect of T2DM attributed to Black race and 54.9% of the effect attributed to Hispanic ethnicity. We found that BGA had almost no direct association with T2DM and was almost entirely mediated by self-identified race/ethnicity and socioeconomic factors. Conclusions It is likely that non-genetic factors, specifically socioeconomic factors, account for much of the reported racial/ethnic disparities in T2DM incidence. PMID:25088753
Melting experiments and field work on Komorní Hùrka volcano, Bohemia, by Johann Wolfgang von Goethe

Horn, Susanne; Kreher-Hartmann, Birgit; Heide, K.

2001-09-01

Johann Wolfgang von Goethe (1749-1832), eminent author, was also state minister and scientist as well as experimentalist in geology. Together with Döbereiner, a chemist in Jena during that time, he carried out melting experiments in porcelain and pottery kilns with rocks and minerals from the volcanic and pseudo-volcanic edifices in NW Bohemia. These experiments were to prove Goethe's theory, that remelting of an archetype rock would result in volcanic and pseudo-volcanic rocks. Especially the formation of the Komorní Hùrka (Kammerberg) volcano in NW Bohemia attracted Goethe during all his life. He visited this location 19 times in 1808, 1820 and 1822 and made very exact field observations. But the interpretation of these observations varied between volcanistic and neptunistic. In order to find arguments, he examined the effect of fire on rocks and minerals using porcelain and pottery kilns. The experiments did not provide the expected results and thus failed to explain the formation of Komorní Hùrka. During Goethe's geognostic work, including the "pyro-technical" experiments, the neptunism-volcanism-controversy about the formation of basalt raged in Europe, and, more general, about rock formation: neptunism-plutonism. Especially the effect of heat on rocks and minerals, i.e. the phenomenology of fire, played an important role in that discussion. Goethe swayed during his lifetime between neptunism and volcanism. He did not fully accept plutonism because he believed, that processes of nature are generally non-violent and that volcanic eruptions and other catastrophic phenomena are the exception rather than the rule. Therefore he tended to neptunistic ideas. In Goethe's notes there are many indications of this conflict. In contrast, the melting experiments are mentioned only few times. It was, however, possible to establish a picture of his experimental work and his fundamental concepts and ideas.

Doctors and pharmacies in the 15th Century only used handwritten copies of the prescription collections available in their time. At the beginning of book printing the publishing of prescription collections immediately became popular. They could be found on the pages of medical and pharmaceutical books of many various editions with different structure and origin, as the forerunner of the official pharmacopoeias. From the 16th Century onwards books with the title "Medicina Pauperum" were published which helped the educated people to tend to themselves, the household, the servants and their immediate surroundings case of an illness. The first work specifically on the topic or of genre of the "Medicina Pauperum" according to our knowledge appeared in Hungarian in the year 1660 and currently seems to survived only in fragments under the title of "Medicina Pauperum", from an unknown author. A rare incident occurred in the present days as a "book" believed to be lost for us turned up from thin air. It is a "copied" manuscript in the size of 97×139 mm attached to the ribs with hemp cord, cropped around and in an unbound state. The book known before only in fractions is now available entirety handwritten on 318 pages, distributed to seven distinct parts. The research of its origin suggests that the author lived and worked in Nagyszombat and was called Johann Misch Astrophilus. The identification of the printing office was possible thanks to the examination of the initials and the gaudily, as well as the fonts and the watermark. By these results the printing very likely occurred in the Brewer Printing Press in Lőcse. For the possibility of more extensive research and value preservation the manuscript was bounded. The facsimile edition contains the magnified and digitalized pages of the original one and is published in numbered issues.

A study of the background radiation in inelastic X-ray scattering (IXS) and X-ray emission spectroscopy (XES) based on an analytical model is presented. The calculation model considers spurious radiation originated from elastic and inelastic scattering processes along the beam paths of a Johann-type spectrometer. The dependence of the background radiation intensity on the medium of the beam paths (air and helium), analysed energy and radius of the Rowland circle was studied. The present study shows that both for IXS and XES experiments the background radiation is dominated by spurious radiation owing to scattering processes along the sample-analyser beam path. For IXS experiments the spectral distribution of the main component of the background radiation shows a weak linear dependence on the energy for the most cases. In the case of XES, a strong non-linear behaviour of the background radiation intensity was predicted for energy analysis very close to the backdiffraction condition, with a rapid increase in intensity as the analyser Bragg angle approaches π / 2. The contribution of the analyser-detector beam path is significantly weaker and resembles the spectral distribution of the measured spectra. Present results show that for usual experimental conditions no appreciable structures are introduced by the background radiation into the measured spectra, both in IXS and XES experiments. The usefulness of properly calculating the background profile is demonstrated in a background subtraction procedure for a real experimental situation. The calculation model was able to simulate with high accuracy the energy dependence of the background radiation intensity measured in a particular XES experiment with air beam paths.

Although we can not find new disclosures or new ways of describing anatomical structures in the "Anatomischen Tabellen", a text-book written by Johann Adam Kulmus (1689-1745), it has had it's influence in the development of medicine, not only in Germany but in Japan. The "Anatomischen Tabellen" has been one of the most published anatomical text-books of the 18th century. This book was concepted by the medical doctor Kulmus, who was born in the German town Breslau and who was living in Danzig, especially to educate the apprentices and fellows of surgeons in German language. Therefore the book was equiped with several copper-plates for illustration. During the years from 1722 to 1814 23 different editions were found, from those were 14 in German, 5 in Latin and one each in French and Netherland. Not one other anatomical textbooks of the 18th century has had such an abundance of editions. The disadvantage of the former used oversized anatomical atlases was their being published in latin and therefore they have been without any use and much too expensive for educational purposes for young surgeons. The "Anatomischen Tabellen" has been the first occidental text-book of anatomy to be translated into japanese to be published in 1774, supplied with numerous wooden engravings.

Screening with low-dose helical computed tomography (CT) has been shown to significantly reduce lung cancer mortality but the optimal target population and time interval to subsequent screening are yet to be defined. We developed two models to stratify individual smokers according to risk of developing lung cancer. We first used the number of lung cancers detected at baseline screening CT in the 5,203 asymptomatic participants of the COSMOS trial to recalibrate the Bach model, which we propose using to select smokers for screening. Next, we incorporated lung nodule characteristics and presence of emphysema identified at baseline CT into the Bach model and proposed the resulting multivariable model to predict lung cancer risk in screened smokers after baseline CT. Age and smoking exposure were the main determinants of lung cancer risk. The recalibrated Bach model accurately predicted lung cancers detected during the first year of screening. Presence of nonsolid nodules (RR = 10.1, 95% CI = 5.57-18.5), nodule size more than 8 mm (RR = 9.89, 95% CI = 5.84-16.8), and emphysema (RR = 2.36, 95% CI = 1.59-3.49) at baseline CT were all significant predictors of subsequent lung cancers. Incorporation of these variables into the Bach model increased the predictive value of the multivariable model (c-index = 0.759, internal validation). The recalibrated Bach model seems suitable for selecting the higher risk population for recruitment for large-scale CT screening. The Bach model incorporating CT findings at baseline screening could help defining the time interval to subsequent screening in individual participants. Further studies are necessary to validate these models.
Small Maf proteins (MafF, MafG, MafK): History, structure and function.

PubMed

Katsuoka, Fumiki; Yamamoto, Masayuki

The small Maf proteins (sMafs) are basic region leucine zipper (bZIP)-type transcription factors. The basic region of the Maf family is unique among the bZIP factors, and it contributes to the distinct DNA-binding mode of this class of proteins. MafF, MafG and MafK are the three vertebrate sMafs, and no functional differences have been observed among them in terms of their bZIP structures. sMafs form homodimers by themselves, and they form heterodimers with cap 'n' collar (CNC) proteins (p45 NF-E2, Nrf1, Nrf2, and Nrf3) and also with Bach proteins (Bach1 and Bach2). Because CNC and Bach proteins cannot bind to DNA as monomers, sMafs are indispensable partners that are required by CNC and Bach proteins to exert their functions. sMafs lack the transcriptional activation domain; hence, their homodimers act as transcriptional repressors. In contrast, sMafs participate in transcriptional activation or repression depending on their heterodimeric partner molecules and context. Mouse genetic analyses have revealed that various biological pathways are under the regulation of CNC-sMaf heterodimers. In this review, we summarize the history and current progress of sMaf studies in relation to their partners. Copyright © 2016 Elsevier B.V. All rights reserved.
High-resolution δ13C record of fossil wood and bulk organic matter from a deep Oligocene lacustrine succession, Bach Long Vi Island, Vietnam

We present a high-resolution stable isotope record based on bulk organic matter (δ13Corg) and fossil wood (δ13Cwood) originating from Oligocene deep lacustrine sediments cored on the Bach Long Vi Island, northern Gulf of Tonkin, offshore Vietnam. The sediments are exceptionally well preserved. They are thus excellently suited for a detailed stratigraphical analysis of the stable isotope record and as proxy for environmental and climatic changes within this period. The sediments were deposited in rapid subsiding, narrow and elongated fault-bound graben (Fyhn and Phach, 2015) and are represented by deep pelagic lacustrine organic-rich mud interrupted by numerous density-flow deposits (Hovikoski et al., 2016). The density-flow deposits contain abundant fragments of fossil wood. Therefore it was possible to obtain 262 coalified wood fragments together with 1063 bulk organic samples throughout the span of the core. This allowed to establish a high resolution stable C isotope record (δ13Corg and δ13Cwood). In addition 2464 handheld XRF determinations were carried out to further characterize the depositional environment (Rizzi et al., 2017). The organic carbon isotope trend from the 500 m core succession provides insight into the palaeoenvironmental changes of the lake during the Oligocene. Both, global and local factors control the δ13C variations. The aim of the study is to obtain pure global δ13Corg and δ13Cwood signals that would allow comparison of the studied sediments with coeval syn-rift successions in the South China Sea region and other parts of the world.

In the middle of the eighteenth century, Carl von Linné, Johann Christoph Gatterer, and Christian Wilhelm Büttner attempted to realize the old idea of deciphering the alphabet of the world, which Francis Bacon had raised as a general postulate of science. This article describes these attempts and their interrelations. Linné used the model of the alphabet to classify plants according to the characters of this fruiting body. Gatterer, one of the leading German historians during the Enlightenment, adopted the botanical method of classification by genus and species to classify the history of scripts. He used the forms of the alphabetic characters to measure the age of manuscripts and to map the process of history as a genealogy of culture. Gatterer collaborated closely with Büttner, the first Göttingen professor of natural history. Büttner constructed a general alphabet of languages which connected the phonetics of language with the historically known alphabets. Early on, diplomatics and ethnography combined the natural order of natural history and the cultural order of the alphabet with the attempt to register development and to document development by the evolution of forms. Based on the shared model of the alphabet and on the common necessity to classify their empirical material, natural history and the description of culture were related attempts in the middle of the eighteenth century to comprehend the alphabetically organized nature and a naturally ordered culture.

To improve the understanding and interpretation of the depositional environment of a late Oligocene lacustrine organic rich oil-prone source rock succession, 2464 hand held (HH)-XRF measurements were made systematically on the 500 m long, continuous core from the fully cored Enreca-3 well. This core, drilled on the remote Bach Long Vi Island, northern Gulf of Tonkin, offshore Vietnam, represents a deep lake succession alternating between lacustrine pelagic dominated sediments interrupted by hyperpycnal turbidites, high density turbidites and debris flows [1, 2]. From a combined HH-XRF-XRD data set, multivariate data analysis and regression models are used to type the rock and to predict the XRD mineral composition based on HH-XRF composition. The rock types and the modelled mineral composition highlight the geochemical variations of the sediment and allows for direct comparison with sedimentological processes and facies changes. The modeling also depicts the cyclic alteration of rock types that are present on many different scales ranging from centimeters to hundreds of meters [1, 2]. The sedimentological and geochemical variations observed throughout the cored section reflects fluctuating paleoclimate, tectonism and hinterland condition controlling the depositional setting, which may provide a deeper understanding of the deposition of this and similar Paleogene syn-rift succession in the South China Sea region. It allows furthermore the development of a more generalized depositional model relevant for other deep-lacustrine syn-rift basins. [1] Petersen et al.

The great German surgeon Theodor Billroth and the imaginative and creative composer Johannes Brahms had a very close friendship centered on musical activities, that lasted for more than thirty years while they lived and worked in Zurich and Vienna, during the second half of the Nineteenth Century. Billroth, besides his all-consuming medical activities, had time to be a musical enthusiast who directed orchestras, played the violin in chamber music groups, and wrote musical criticism for newspapers. The common affection between these two creative giants is documented by their abundant and effusive correspondence, by the constant requests by Brahms of Billroth's opinions regarding his compositions, and by the positive and stimulating answers that Billroth gave to these requests. Billroth opened his house for musical evenings to play Brahms chamber compositions for the first time, and Brahms dedicated his two Opus 51 string quartets Nos. 1 and 2, known in the musical milieu as Billroth I and II, to his physician friend. Unfortunately, the close bonds between these two geniuses weakened towards the end of their lives as a result of Billroth's becoming intolerant to the lack of social refinements and gruff behavior of the composer. This baffling intolerance of Billroth to his friend Brahms can be better understood after reading Billroth's writings in his book The Medical Sciences in the German Universities. A Study in the History of Civilization. There Billroth expresses strong prejudices against potential medical students of humble social origins, such as those of Brahms, coupled to a primitive anti-Semitism.

The implementation of microbial fecal source tracking (MST) methods in drinking water management is limited by the lack of knowledge on the transport and decay of host-specific genetic markers in water sources. To address these limitations, the decay and transport of human (BacH) and ruminant (BacR) fecal Bacteroidales 16S rRNA genetic markers in a drinking water source (Lake Rådasjön in Sweden) were simulated using a microbiological model coupled to a three-dimensional hydrodynamic model. The microbiological model was calibrated using data from outdoor microcosm trials performed in March, August, and November 2010 to determine the decay of BacH and BacR markers in relation to traditional fecal indicators. The microcosm trials indicated that the persistence of BacH and BacR in the microcosms was not significantly different from the persistence of traditional fecal indicators. The modeling of BacH and BacR transport within the lake illustrated that the highest levels of genetic markers at the raw water intakes were associated with human fecal sources (on-site sewers and emergency sewer overflow). This novel modeling approach improves the interpretation of MST data, especially when fecal pollution from the same host group is released into the water source from different sites in the catchment.

A Tale of Two Inlets: Tidal Currents at Two Adjacent Inlets in the Indian River Lagoon

Webb, B. M.; Weaver, R. J.

2012-12-01

The tidal currents and hydrography at two adjacent inlets of the Indian River Lagoon estuary (Florida) were recently measured using a personal watercraft-based coastal profiling system. Although the two inlets—Sebastian Inlet and Port Canaveral Inlet—are separated by only 60 km, their characteristics and dynamics are quite unique. While Sebastian Inlet is a shallow (~4 m), curved inlet with a free connection to the estuary, Port Canaveral Inlet is dominated by a deep (~13 m), straight ship channel and has limited connectivity to the Banana River through a sector gate lock. Underway measurements of tidal currents were obtained using a bottom tracking acoustic Doppler current profiler; vertical casts of hydrography were obtained with a conductivity-temperature-depth profiling instrument; and continuous underway measurements of surface water hydrography were made using a Portable SeaKeeper system. Survey transects were performed to elucidate the along-channel variability of tidal flows, which appears to be significant in the presence of channel curvature. Ebb and flood tidal currents in Sebastian Inlet routinely exceeded 2.5 m/s from the surface to the bed, and an appreciable phase lag exists between tidal stage and current magnitude. The tidal currents at Port Canaveral Inlet were much smaller (~0.2 m/s) and appeared to be sensitive to meteorological forcing during the study period. Although the lagoon has free connections to the ocean 145 km to the north and 45 km to the south, Sebastian Inlet likely drains much of the lagoon to its north, an area of ~550 sq. km.

Behavior-aware cache hierarchy optimization for low-power multi-core embedded systems

NASA Astrophysics Data System (ADS)

Zhao, Huatao; Luo, Xiao; Zhu, Chen; Watanabe, Takahiro; Zhu, Tianbo

2017-07-01

In modern embedded systems, the increasing number of cores requires efficient cache hierarchies to ensure data throughput, but such cache hierarchies are restricted by their tumid size and interference accesses which leads to both performance degradation and wasted energy. In this paper, we firstly propose a behavior-aware cache hierarchy (BACH) which can optimally allocate the multi-level cache resources to many cores and highly improved the efficiency of cache hierarchy, resulting in low energy consumption. The BACH takes full advantage of the explored application behaviors and runtime cache resource demands as the cache allocation bases, so that we can optimally configure the cache hierarchy to meet the runtime demand. The BACH was implemented on the GEM5 simulator. The experimental results show that energy consumption of a three-level cache hierarchy can be saved from 5.29% up to 27.94% compared with other key approaches while the performance of the multi-core system even has a slight improvement counting in hardware overhead.

We report on a newly discovered letter by Christoph Rothmann, dated July 1st 1584, and addressed to Johann Ernst of Anhalt. The letter supports the earlier assumption that Johann Ernst recommended Rothmann to Landgrave Wilhelm of Hesse, as Rothmann asks for Johann Ernst's help on the matter in this new source. More importantly Rothmann refers to his attempts to make Copernicus' calculations compatible with the Ptolomean model, which demonstrates that already at this stage of his career he was working on such a compromise, and not only after being influenced by Raimarus Ursus or Tycho Brahe, as has been argued by some authors.
"St. Patrick's Aurora"

NASA Image and Video Library

2015-03-17

Geomagnetic Storms Sometimes during the solar magnetic events, solar explosions hurl clouds of magnetized particles into space. Traveling more than a million miles per hour, these coronal mass ejections, or CMEs, made up of hot material called plasma take up to three days to reach Earth. Spacecraft and satellites in the path of CMEs can experience glitches as these plasma clouds pass by. In near-Earth space, magnetic reconnection incites explosions of energy driving charged solar particles to collide with atoms in Earth’s upper atmosphere. We see these collisions near Earth’s polar regions as the aurora. The prevalence of specific gases in the atmosphere determines the color of the aurora. For example, if charged particles strike oxygen atoms, the aurora will appear green. Excited nitrogen closer to 60 miles above Earth’s surface will produce a blood red color. Three spacecraft from NASA’s Time History of Events and Macroscale Interactions during Substorms (THEMIS) mission, observe these outbursts known as substorms. Substorms can intensify aurora’s near Earth’s poles.

The Nares Strait problem: A re-evaluation of the geological evidence in terms of a diffuse oblique-slip plate boundary between Greenland and the Canadian Arctic Islands

NASA Astrophysics Data System (ADS)

Miall, Andrew D.

1983-12-01

Geophysical models of sea floor spreading in Baffin Bay-Labrador Sea require that Greenland was displaced sinistrally relative to the Canadian Arctic Islands by 200-300 km. It has usually been assumed that this movement took place along Nares Strait, but onshore geological evidence recently compiled by Dawes and Kerr appears to rule out any displacement in excess of 50 km. Twenty different structural and stratigraphic markers cross the strait without significant displacement. A new approach is suggested here, which spreads the displacement across a diffuse oblique-slip plate boundary: (1) South of Bache Peninsula displacement of up to about 150 km may have occurred along Nares Strait. Bache Peninsula Arch probably did not cross the strait but is a north-south feature extending south from Bache Peninsula. (2) Revisions of Proterozoic stratigraphy show that the arch cannot have marked the limit of Thule Basin, as formerly assumed. Thule Basin isopach data can readily be accommodated to a 150 km sinistral displacement. (3) Cambrian-Ordovician strata in Bache Peninsula area may have occupied a north-south embayment similar to others along the southern border of Franklinian Geosyncline. (4) North of Bache Peninsula most of the strike-slip displacement probably took place along strike faults within Central Ellesmere and North Greenland fold belts. Paleozoic stratigraphic markers which cross Nares Strait without strike-slip displacement would not be displaced by these faults either, because stratigraphic and structural trends are parallel within the fold belts. The structural style of the Ellesmere fold belt is probably one of transpressive oblique-slip with local counterclockwise block rotations. (5) Up to 50 km of displacement may have occurred along northern Nares Strait itself, probably as a late phase of movement. A detailed palinspastic reconstruction must await further detailed groundwork. This should include the following (which would also serve as independent

The protection of drinking water from pathogens such as Cryptosporidium and Giardia requires an understanding of the short-term microbial release from faecal contamination sources in the catchment. Flow-weighted samples were collected during two rainfall events in a stream draining an area with on-site sewers and during two rainfall events in surface runoff from a bovine cattle pasture. Samples were analysed for human (BacH) and ruminant (BacR) Bacteroidales genetic markers through quantitative polymerase chain reaction (qPCR) and for sorbitol-fermenting bifidobacteria through culturing as a complement to traditional faecal indicator bacteria, somatic coliphages and the parasitic protozoa Cryptosporidium spp. and Giardia spp. analysed by standard methods. Significant positive correlations were observed between BacH, Escherichia coli, intestinal enterococci, sulphite-reducing Clostridia, turbidity, conductivity and UV254 in the stream contaminated by on-site sewers. For the cattle pasture, no correlation was found between any of the genetic markers and the other parameters. Although parasitic protozoa were not detected, the analysis for genetic markers provided baseline data on the short-term faecal contamination due to these potential sources of parasites. Background levels of BacH and BacR makers in soil emphasise the need to including soil reference samples in qPCR-based analyses for Bacteroidales genetic markers.

Following the amendment of the Medical Licensure Act (ÄAppO) in 2012, pain medicine was introduced as a mandatory subject for students during undergraduate medical training. Medical schools were required to define and to implement adequate curricular and formal teaching structures based on interdisciplinary and multiprofessional requirements according to the curriculum for pain medicine of the German Pain Society. These aspects were considered in the new interdisciplinary curriculum for pain medicine, the so-called Mainz model. A new curriculum based on the Kern cycle was developed and implemented at the Medical Center of the Johannes Gutenberg University in Mainz. Different teaching methods (lectures, interprofessional tutorials and bedside coaching in small groups) were used to impart professional expertise in pain medicine to medical students in an interdisciplinary clinical context. The new curriculum was put into practice and evaluated starting from the winter semester 2014/2015. Before and after the first implementation, medical students were asked about the relevance of pain medicine and their perception of personal competence. The interdisciplinary course in pain medicine was successfully introduced into the degree program based on the curriculum of the German Pain Society and the Kern cycle. With educational support, interdepartmental and multiprofessional collaboration the process of implementation of new interdisciplinary courses can be facilitated. In the future, the question how to increase the amount of practical lessons without increasing the load on teaching resources has to be resolved. Blended learning modules, such as a combination of E‑learning and practical lessons are currently being studied in smaller cohorts.

Anti-inflammatory genes associated with multiple sclerosis: a gene expression study.

Multiple sclerosis (MS) is an autoimmune inflammatory disease of the central nervous system caused by a complex interaction between multiple genes and environmental factors. HLA region is the strongest susceptibility locus, but recent huge genome-wide association studies identified new susceptibility genes. Among these, BACH2, PTGER4, RGS1 and ZFP36L1 were highlighted. Here, a gene expression analysis revealed that three of them, namely BACH2, PTGER4 and ZFP36L1, are down-regulated in MS patients' blood cells compared to healthy subjects. Interestingly, all these genes are involved in the immune system regulation with predominant anti-inflammatory role and their reduction could predispose to MS development.

Holocene climate change in North Africa and the end of the African humid period - results of new high-resolution transient simulations with the MPI-ESM 1.3

NASA Astrophysics Data System (ADS)

Dallmeyer, Anne; Claussen, Martin; Lorenz, Stephan

2017-04-01

The Max-Planck-Institute for Meteorology has recently undertaken high-resolution transient Holocene simulations using the fully-coupled Earth System Model MPI-ESM 1.3. The simulations cover the last 8000 years and are forced not only by reconstructed Holocene orbital variations and atmospheric greenhouse gas concentrations, but also by recent compilations of Holocene volcanic aerosol distributions, variations in spectral solar irradiance, stratospheric ozone and land-use change. The simulations reveal the ubiquitous "Holocene conundrum": simulated global mean temperatures increase during the mid-Holocene and stay constant during the late Holocene. Simulated mid-Holocene near-surface temperatures are too cold in large parts of the world. Simulated precipitation, however, agrees much better with reconstruction than temperatures do. Likewise simulated global biome pattern fit reconstructions nicely, except for North Western America. First results of these simulations are presented with the main focus on the North African monsoon region. The amplitude of the mid-Holocene African Humid Period (AHP) is well captured in terms of precipitation and vegetation cover, so is the south-ward transgression of the termination of the AHP seen in reconstructions. The Holocene weakening and southward retreat of the North African monsoon as well as changes in the monsoon dynamic including shifts in the seasonal cycle and their relation to the locally varying termination of the AHP are discussed in detail. Members of the Hamburg Holocene Team: Jürgen Bader (1), Sebastian Bathiany (2), Victor Brovkin (1), Martin Claussen (1,3), Traute Crüger (1), Roberta D'agostino (1), Anne Dallmeyer (1), Sabine Egerer (1), Vivienne Groner (1), Matthias Heinze (1), Tatiana Ilyina (1), Johann Jungclaus (1), Thomas Kleinen (1), Alexander Lemburg (1), Stephan Lorenz (1), Thomas Raddatz (1), Hauke Schmidt (1), Gerhard Schmiedl (3), Bjorn Stevens (1), Claudia Timmreck (1), Matthew Toohey (4) (1) Max

Oxidative stress has been considered a major contributing factor to traumatic brain injury (TBI). Formononetin, a phytoestrogen that belongs to the flavonoid family, is extracted from plants and herbs such as the red clover. Growing evidence demonstrates that formononetin has antioxidant properties. Therefore, formononetin has potential use in treating oxidative stress injuries in TBI. In this study, the neuroprotective and antioxidant effects of formononetin against TBI, as well as the related probable mechanisms, were investigated. The TBI model was produced in male Wistar rats through Feeney's weight-drop model. At 1 day after TBI, the neurological function score and brain water content were assessed. TUNEL assay was used to determine neuronal apoptosis. The expression levels of miR-155, HO-1, and BACH1 were measured by RT-PCR and western blotting. Consequently, our ﬁndings showed that formononetin pretreatment for 5 days signiﬁcantly improved the neurological scores, reduced brain edema and inhibited neuronal apoptosis in rats after TBI. MiR-155 was substantially decreased and BACH1 expression was significantly increased in the TBI model, while pretreatment with formononetin dramatically up-regulated the expression levels of miR-155 and HO-1 and down-regulated the protein expression of BACH1 in rats after TBI. In summary, formononetin has been shown to have neuroprotective effects, and the mechanisms of this effect may be associated with its inhibition of oxidative stress and activation of Nrf2-dependent antioxidant pathways in TBI.

In protein structure prediction it is of crucial importance, especially at the refinement stage, to score efficiently large sets of models by selecting the ones that are closest to the native state. We here present a new computational tool, BACHSCORE, that allows its users to rank different structural models of the same protein according to their quality, evaluated by using the BACH++ (Bayesian Analysis Conformation Hunt) scoring function. The original BACH statistical potential was already shown to discriminate with very good reliability the protein native state in large sets of misfolded models of the same protein. BACH++ features a novel upgrade in the solvation potential of the scoring function, now computed by adapting the LCPO (Linear Combination of Pairwise Orbitals) algorithm. This change further enhances the already good performance of the scoring function. BACHSCORE can be accessed directly through the web server: bachserver.pd.infn.it.

Although triple negative breast cancers (TNBC) are the most aggressive subtype of breast cancer, they currently lack targeted therapies. Because this classification still includes a heterogeneous collection of tumors, new tools to classify TNBCs are urgently required in order to improve our prognostic capability for high risk patients and predict response to therapy. We previously defined a gene expression signature, RKIP Pathway Metastasis Signature (RPMS), based upon a metastasis-suppressive signaling pathway initiated by Raf Kinase Inhibitory Protein (RKIP). We have now generated a new BACH1 Pathway Metastasis gene signature (BPMS) that utilizes targets of the metastasis regulator BACH1. Specifically, we substituted experimentally validated target genes to generate a new BACH1 metagene, developed an approach to optimize patient tumor stratification, and reduced the number of signature genes to 30. The BPMS significantly and selectively stratified metastasis-free survival in basal-like and, in particular, TNBC patients. In addition, the BPMS further stratified patients identified as having a good or poor prognosis by other signatures including the Mammaprint® and Oncotype® clinical tests. The BPMS is thus complementary to existing signatures and is a prognostic tool for high risk ER-HER2- patients. We also demonstrate the potential clinical applicability of the BPMS as a single sample predictor. Together, these results reveal the potential of this pathway-based BPMS gene signature to identify high risk TNBC patients that can respond effectively to targeted therapy, and highlight BPMS genes as novel drug targets for therapeutic development.

The types of thirty-two nominal weevil species described by Johann Christian Fabricius are reviewed and lecto- and paralectotypes are designated for twenty-two of them. A neotype is designated for Curculiosticticus Fabricius, 1777. Protapionvaripes (Germar, 1817) is declared a nomen protectum over Curculioflavipes Fabricius, 1775. Based on a study of syntypes, Rhinomacercurculioides Fabricius, 1781 is confirmed as a member of Mycterus (Mycteridae), Bruchusundatus Fabricius, 1787 is tentatively transferred to Erotylidae, Curculiofulvirostris Fabricius, 1787 and Anthribusroboris Fabricius, 1798 are confirmed as members of Salpingus (Salpingidae), and Brachyceruscristatus Fabricius, 1798 is transferred to Tenebrionidae. Based on lectotype designation, Curculiocaninus Fabricius, 1792 is confirmed as a synonym of Sitonalineatus (Linnaeus, 1758) and Curculioinnocuus Fabricius, 1802 as a synonym of Cneorhinusbarcelonicus (Herbst, 1797). Bruchusrufipes Fabricius, 1792 is not considered an available species name, but a later use of Bruchusrufipes Olivier, 1790. Cossonusincisus Pascoe, 1885 is reinstated as valid from synonymy under Cossonusilligeri Champion, 1909 and Cossonusvulneratus Illiger, 1805 from synonymy under Cossonuscanaliculatus (Fabricius, 1792) (a primary homonym of Curculiocanaliculatus Olivier, 1791). Cossonuscanaliculatus Fabricius, 1802 is a secondary homonym of the former and is replaced with Cossonusincisus. Salpingusfulvirostris (Fabricius, 1787) is reinstated as valid from synonymy under Salpingusplanirostris (Fabricius, 1787), a primary homonym of Curculioplanirostris Piller & Mitterpacher, 1783. The following new combinations are proposed: Brachysomuserinaceus (Fabricius, 1802) (from Curculio), Bronchusferus (Gyllenhal, 1840) (from Hipporhinus), Bronchusglandifer (Fabricius, 1792) (from Curculio), Bronchusnivosus (Sparrman, 1785) (from Curculio), Bronchussparrmani (Gyllenhal, 1833) (from Hipporhinus), Coelocephalapionatrirostre (Fabricius, 1802

Lytic infection by the Epstein-Barr virus (EBV) poses numerous health risks, such as infectious mononucleosis and lymphoproliferative disorder. Proteins in the bromodomain and extraterminal (BET) family regulate multiple stages of viral life cycles and provide promising intervention targets. Synthetic small molecules can bind to the bromodomains and disrupt function by preventing recognition of acetylated lysine substrates. We demonstrate that JQ1 and other BET inhibitors block two different steps in the sequential cascade of the EBV lytic cycle. BET inhibitors prevent expression of the viral immediate-early protein BZLF1. JQ1 alters transcription of genes controlled by the host protein BACH1, and BACH1 knockdown reduces BZLF1 expression. BET proteins also localize to the lytic origin of replication (OriLyt) genetic elements, and BET inhibitors prevent viral late gene expression. There JQ1 reduces BRD4 recruitment during reactivation to preclude replication initiation. This represents a rarely observed dual mode of action for drugs.

The present special issue contains a collection of Original Papers dedicated to Professor Johannes Heydenreich on the occasion of his 75th birthday.Johannes Heydenreich, born on 20 June 1930 in Plauen/Vogtland near Dresden, studied physics at the Pädagogische Hochschule Potsdam, where he obtained his first academic degree Dipl. Phys. in 1958. He received his doctoral degree at the Martin Luther University in Halle in 1961 and the Habilitation degree in 1969. Already during his studies in Potsdam, he showed an interest in electron microscopy due to the influence of his teacher and supervisor Prof. Picht, one of the pioneers in electron optics. His interests were strengthened when Johannes Heydenreich did the experimental work for his Diploma degree at the Institute for Experimental Physics of the University of Halle, where he met Prof. Heinz Bethge for the first time. This was the beginning of a fruitful and longstanding collaboration. In 1962 Johannes Heydenreich joined the team of the later Institute for Solid State Physics and Electron Microscopy of the Academy of Sciences of the GDR, in Halle, for which the basis was laid by Prof. Bethge in 1960.Heydenreich has been working as Assistant Director for many years and played a decisive role in introducing and organising the various techniques of electron microscopy in the institute.The research activities of Prof. Heydenreich covered a broad spectrum over the years. At the beginning of his career he made significant contributions in the field of electron mirror microscopy. After that, his main interests were focused on transmission electron microscopy, ranging from diffraction contrast analysis of crystal defects to high-resolution electron microscopy and image processing. His favourite field was studies of defect-induced phenomena in advanced materials.

Featured Image: Orbiting Stars Share an Envelope

Kohler, Susanna

2016-03-01

This beautiful series of snapshots from a simulation (click for a better look!) shows what happens when two stars in a binary system become enclosed in the same stellar envelope. In this binary system, one of the stars has exhausted its hydrogen fuel and become a red giant, complete with an expanding stellar envelope composed of hydrogen and helium. Eventually, the envelope expands so much that the companion star falls into it, where it releases gravitational potential energy into the common envelope. A team led by Sebastian Ohlmann (Heidelberg Institute for Theoretical Studies and University of Wrzburg) recently performed hydrodynamic simulations of this process. Ohlmann and collaborators discovered that the energy release eventually triggers large-scale flow instabilities, which leads to turbulence within the envelope. This process has important consequences for how these systems next evolve (for instance, determining whether or not a supernova occurs!). You can check out the authors video of their simulated stellar inspiral below, or see their paper for more images and results from their study.CitationSebastian T.

Woersching, Joanna C; Snyder, Audrey E

2004-01-01

In 2001, the mountain town of San Sebastian, El Salvador experienced a series of earthquakes that affected the livelihood of its people. A convenience sample of 100 households of 594 inhabitants of San Sebastian and the surrounding rural farming areas was completed. One study participant for each household was evaluated for mental health and psychosocial changes after the earthquakes. The participant's questionnaire was used to investigate the relationship between physical health, access to health care, housing, food and water, and the occurrence of negative mental health markers six months after the disasters. Findings indicate that the majority (67%) of respondents experienced 6 or more mental health complaints. Risk factors associated with multiple negative mental health symptoms included change in household income and loss of job, a new illness or a new injury in the household, reliance on healthcare services since the earthquake, and managing a chronic illness. Findings indicate a need for rapid, acute mental health screening with at-risk groups and the need to educate the entire community regarding what medical and mental health treatments are available to reduce barriers to treatment and increase public awareness.
Early identification of acute heart failure at the time of presentation: do natriuretic peptides make the difference?

2018-06-01

The early identification of patients with acute heart failure (AHF) is challenging as many other diseases lead to a clinical presentation with dyspnea. The aim of the study was to evaluate the impact of natriuretic peptides at common HF study cut-offs on the diagnosis of patients with dyspnea at admission. For this post hoc analysis, we analysed n = 726 European Union (EU) patients from the prospective BACH (Biomarkers in Acute Heart Failure) study. Cut-offs were 350 ng/L (BNP), 300 pmol/L [pro-atrial natriuretic peptide (proANP)], and 1800 ng/L (NT-proBNP). These cut-offs had equivalent 90 days' mortality in the EU cohort of BACH. We analysed the effect of selection using these cut-offs on the prevalence of the gold standard diagnoses made in the BACH study and the respective mortality. The prevalence of AHF is increased from 47.5 to 75.6% (NT-proBNP criteria) up to 79.7% (BNP criteria). With the use of the proANP criteria, 90 days' mortality of patients with AHF rose from 14 to 17% (P = 0.029). In the group with no-AHF diagnoses, mortality rose from 10 to 25% (P < 0.001). The prevalence of patients with the gold standard diagnoses of AHF among those presenting with dyspnea to the emergency department is significantly increased by the use of natriuretic peptides with common cut-offs used in prospective HF studies. Nevertheless, in the selected groups, patients with no AHF diagnosis have the highest mortality, and therefore, the addition of a natriuretic peptide alone is insufficient to start specific therapies. © 2018 The Authors.

It is unclear how long low-dose computed tomographic (LDCT) screening should continue in populations at high risk of lung cancer. We assessed outcomes and the predictive ability of the COSMOS prediction model in volunteers screened for 10 years. Smokers and former smokers (>20 pack-years), >50 years, were enrolled over one year (2000-2001), receiving annual LDCT for 10 years. The frequency of screening-detected lung cancers was compared with COSMOS and Bach risk model estimates. Among 1035 recruited volunteers (71% men, mean age 58 years) compliance was 65% at study end. Seventy-one (6.95%) lung cancers were diagnosed, 12 at baseline. Disease stage was: IA in 48 (66.6%); IB in 6; IIA in 5; IIB in 2; IIIA in 5; IIIB in 1; IV in 5; and limited small cell cancer in 3. Five- and ten-year survival were 64% and 57%, respectively, 84% and 65% for stage I. Ten (12.1%) received surgery for a benign lesion. The number of lung cancers detected during the first two screening rounds was close to that predicted by the COSMOS model, while the Bach model accurately predicted frequency from the third year on. Neither cancer frequency nor proportion at stage I decreased over 10 years, indicating that screening should not be discontinued. Most cancers were early stage, and overall survival was high. Only a limited number of invasive procedures for benign disease were performed. The Bach model - designed to predict symptomatic cancers - accurately predicted cancer frequency from the third year, suggesting that overdiagnosis is a minor problem in lung cancer screening. The COSMOS model - designed to estimate screening-detected lung cancers - accurately predicted cancer frequency at baseline and second screening round. Copyright © 2013 Elsevier Ireland Ltd.

Potential sex differences in EEG coherent activity during pleasant and unpleasant musical emotions were investigated. Musical excerpts by Mahler, Bach, and Prodromidès were played to seven men and seven women and their subjective emotions were evaluated in relation to alpha band intracortical coherence. Different brain links in specific frequencies were associated to pleasant and unpleasant emotions. Pleasant emotions (Mahler, Bach) increased upper alpha couplings linking left anterior and posterior regions. Unpleasant emotions (Prodromidès) were sustained by posterior midline coherence exclusively in the right hemisphere in men and bilateral in women. Combined music induced bilateral oscillations among posterior sensory and predominantly left association areas in women. Consistent with their greater positive attributions to music, the coherent network is larger in women, both for musical emotion and for unspecific musical effects. Musical emotion entails specific coupling among cortical regions and involves coherent upper alpha activity between posterior association areas and frontal regions probably mediating emotional and perceptual integration. Linked regions by combined music suggest more working memory contribution in women and attention in men.
A Genome-wide Regulatory Network Identifies Key Transcription Factors for Memory CD8+ T Cell Development

PubMed Central

Hu, Guangan; Chen, Jianzhu

2014-01-01

Memory CD8+ T cell development is defined by the expression of a specific set of memory signature genes (MSGs). Despite recent progress, many components of the transcriptional control of memory CD8+ T cell development are still unknown. To identify transcription factors (TFs) and their interactions in memory CD8+ T cell development, we construct a genome-wide regulatory network and apply it to identify key TFs that regulate MSGs. Most of the known TFs in memory CD8+ T cell development are rediscovered and about a dozen new TFs are also identified. Sox4, Bhlhe40, Bach2 and Runx2 are experimentally verified and Bach2 is further shown to promote both development and recall proliferation of memory CD8+ T cells through Prdm1 and Id3. Gene perturbation study identifies the mode of interactions among the TFs with Sox4 as a hub. The identified TFs and insights into their interactions should facilitate further dissection of molecular mechanisms underlying memory CD8+ T cell development. PMID:24335726

Investigations into the chemistry, toxicology, metabolism and possible mode of action of O-ethyl S-methyl ethylphosphonothioate

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hur, J.H.

1989-01-01

The chemical and metabolic oxidation of O-ethyl S-methyl ethylphosphonthioate (1) as a model compound was studied. This compound has the following toxicological properties: LD{sub 50} (rat) 4.6 mg/kg, LD{sub 50}(HF) 14.0 ug/g; k{sub i}(BAChE) {equals} 303, k{sub i}(HFAChE) {equals} 623. {sup 13} C- and {sup 31}P-NMR were mainly used in this study. The chemical oxidation of 1 with m-CPBA in CDCl{sub 3} resulted in the formation of O-ethyl ethylphosphonic acid (2), O-ethyl ethylphosphinyloxymethylsulfonate (3) and O-ethyl ethylphosphonic acid anhydride (4). However, oxidation reaction of the model compound 1 with MPPA in D{sub 2}O gave 2 and methylsulfonic acid. 1 wasmore » incubated in vitro with rat liver microsomal oxidase, and 2 and methylsulfenic acid were observed along with 1. For the in vivo study, a number of houseflies were treated with 14ug/g (LD{sub 50} level) of 1. Analysis of the extracts of metabolic products provided evidence of the formation of 2. The existence of 1 S-oxide was demonstrated by use of a trapping method and the observation of oxidation products. The S-oxide has been proposed as a possible active intermediate responsible for the high toxicity of 1 to animals. However, owing to its instability it is unlikely that the S-oxide intermediate would persist in an aqueous biological environment long enough to attack the target enzyme. 4 was shown to have high toxicity to the rat and housefly and was also a potent anticholinesterase against BAChE and HFAChE . The presence of 4 was observed directly by the monitoring experiments during the chemical oxidation in aqueous conditions. This provided evidence that this metabolite is stable enough to attack the target site in biological systems. The anhydride 4 is proposed as the active metabolite in in vivo systems, responsible for high toxicity of 1.« less

Paleček, Pavel

2016-09-01

At almost 90 years of age, we have lost the author of the founding historical works on Johann Gregor Mendel. Vítězslav Orel served for almost 30 years as the editor of the journal Folia Mendeliana. His work was beset by the wider problems associated with Mendel's recognition in the Communist Bloc, and by the way in which narratives of the history of science could be co-opted into the service of Cold War and post-Cold War political agendas. Orel played a key role in the organization of the Mendel symposium of 1965 in Brno, and has made a strong contribution to the rehabilitation of genetics generally, and to championing the work of Johann Gregor Mendel in particular. With Jaroslav Kříženecký, he cofounded the Mendelianum in Brno, which for decades has served as an intellectual bridge between the East and West. Orel's involvement with this institution exposed him to dangers both during and after the Cold War.
Phrenology and physiognomy in Victorian literature.

PubMed

Boshears, Rhonda; Whitaker, Harry

2013-01-01

Phrenology evolved from the work of Franz Joseph Gall (1758-1828) and Johann Gaspar Spurzheim (1776-1832), becoming a fixture in Victorian culture, arts and letters as well as medicine. Writers such as Thomas Love Peacock (1785-1866) and Thomas Hood (1799-1845) initially satirized phrenology, as did playwright and composer William S. Gilbert (1836-1911). On the other hand, novelists such as Charlotte Brontë (1816-1855), Charles Dickens (1812-1870), George Eliot (1819-1880), and the poet and essayist Ralph Waldo Emerson (1803-1882) not only accepted the principles of this brain-based personality theory but exploited it in their characters. The popularity of phrenology in the Victorian period should in part be attributed to the popularity of physiognomy which, thanks in large part to Johann Christian Lavater (1741-1801), has been thoroughly embedded in Western culture since the end of the eighteenth century. © 2013 Elsevier B.V.

MicroRNAs (miRNAs) constitute an important class of non-coding RNA implicated in gene expression regulation. More than 1900 miRNA molecules have been identified in humans and their modulation during viral infection and it is recognized to play a role in latency regulation or in establishing an antiviral state. The liver cells are targets during DENV infection, and alteration of liver functions contributes to severe disease. In this work the miRNAs expression profile of the human hepatoma cell line, Huh-7, infected with DENV-2 was determined using microarray and real-time PCR. Let-7c is one of the miRNAs up-regulated during DENV infection in the hepatic Huh-7 as well as in the macrophage-monocytic cell line U937-DC-SIGN. Let-7c overexpression down-regulates both DENV-2 and DENV-4 infection. Additionally, we found that the transcription factor BACH1, a let-7c target, is also down-regulated during DENV infection. In accordance with this finding, HO-1, the main responsive factor of BACH1 was found up-regulated. The up-regulation of HO-1 may contribute to the stress oxidative response in infected cells.

FANCM-FAAP24 and FANCJ: FA proteins that metabolize DNA

PubMed Central

Ali, Abdullah Mahmood; Singh, Thiyam Ramsing; Meetei, Amom Ruhikanta

2009-01-01

Fanconi anemia (FA) is a rare autosomal recessive or X-linked disorder characterized by aplastic anemia, cancer susceptibility and cellular sensitivity to DNA crosslinking agents. Eight FA proteins (FANCA, -B, -C, -E, -F, -G, -L and –M) and three non-FA proteins (FAAP100, FAAP24 and HES1) form the FA nuclear core complex that is required for monoubiquitination of the FANCD2-FANCI dimer upon DNA damage. The other three FA proteins, FANCD1/BRCA2, FANCJ/BACH1/BRIP1 and FANCN/PALB2, act in parallel or downstream of the FANCD2-FANCI dimer. Despite the isolation and characterization of several FA proteins, the mechanism by which these proteins protect cells from DNA interstrand crosslinking agents has been unclear. This is because a majority of the FA proteins lack any recognizable functional domains that can provide insight into their function. The recently discovered FANCM (Hef) and FANCJ (BRIP1/BACH1) proteins contain helicase domains, providing potential insight into the role of FA proteins in DNA repair. FANCM with its partner, FAAP24, and FANCJ bind and metabolize a variety of DNA substrates. In this review, we focus on the discovery, structure, and function of the FANCM-FAAP24 and FANCJ proteins.

Intracellular degradation of functionalized carbon nanotube/iron oxide hybrids is modulated by iron via Nrf2 pathway

The in vivo fate and biodegradability of carbon nanotubes is still a matter of debate despite tremendous applications. In this paper we describe a molecular pathway by which macrophages degrade functionalized multi-walled carbon nanotubes (CNTs) designed for biomedical applications and containing, or not, iron oxide nanoparticles in their inner cavity. Electron microscopy and Raman spectroscopy show that intracellularly-induced structural damages appear more rapidly for iron-free CNTs in comparison to iron-loaded ones, suggesting a role of iron in the degradation mechanism. By comparing the molecular responses of macrophages derived from THP1 monocytes to both types of CNTs, we highlight a molecular mechanism regulated by Nrf2/Bach1 signaling pathways to induce CNT degradation via NOX2 complex activation and O2•−, H2O2 and OH• production. CNT exposure activates an oxidative stress-dependent production of iron via Nrf2 nuclear translocation, Ferritin H and Heme oxygenase 1 translation. Conversely, Bach1 was translocated to the nucleus of cells exposed to iron-loaded CNTs to recycle embedded iron. Our results provide new information on the role of oxidative stress, iron metabolism and Nrf2-mediated host defence for regulating CNT fate in macrophages. PMID:28120861

Black, F. O.; Paloski, W. H.; Bloomberg, J. J.; Wood, S. J.

2007-01-01

Integration of multi-sensory inputs to detect tilts relative to gravity is critical for sensorimotor control of upright orientation. Displaying body orientation using electrotactile feedback to the tongue has been developed by Bach-y- Rita and colleagues as a sensory aid to maintain upright stance with impaired vestibular feedback. This investigation has explored the effects of Tongue Elecrotactile Feedback (TEF) for control of posture and movement as a sensorimotor countermeasure, specifically addressing the optimal location of movement sensors.

Results reported in Part I of the Earthquakes in El Salvador series (see Disaster Management & Response 2003;1:105-9) indicated clinically relevant findings. The findings indicated a need for greater public health action within all five categories reviewed: healthcare, access to healthcare, housing, food, water and sanitation. Significant results between urban and rural communities indicated a need for broader community aid, public health and sanitation services to rural areas. Faster and more efficient disaster management and care services throughout the San Sebastian community were also necessary modifications.
Some Historical Points of Interest in Göttingen

NASA Astrophysics Data System (ADS)

Hentschel, Klaus

The Georgia Augusta University of Göttingen, founded in 1737, was a child of the Enlightenment, and the new sciences have always played a major role here.1 Among the teachers of physics, physical chemistry, astronomy, and related subjects we find Johann Christian Polykarp Erxleben, Georg Christoph Lichtenberg, Johann Tobias Mayer, Carl Friedrich Gauss, Johann B. Listing, Wilhelm Eduard Weber, Woldemar Voigt, Friedrich Kohlrausch, Eduard Riecke, Walther Nernst and Peter Debye — the last two subsequently moved on to Berlin. In the 1920s, physics students were jestingly referred to as “Frankierte, Bornierte und Polierte” (loosely translated as stamped, limited and polished), in allusion to their teachers, the theoretical physicist Max Born and the experimentalists James Franck and Robert Wichard Pohl, the first two being important figures in the history of quantum theory, the third, one of the founding fathers of experimental solid state physics.2 The National Socialist’s rise to power had a devastating effect on this world-renowned center for physics and mathematics. Most of its high-caliber scientists either were dismissed on the basis of the racist “Law for the Restoration of the Professional Civil Service” or themselves felt compelled to emigrate: About a dozen members of the physics faculty, including Born and Franck, and ten from the mathematics faculty left Göttingen.3 After the war, Richard Becker, who in 1936 had received a compulsory order to take the chair for theoretical physics vacant since Born’s emigration, and Friedrich Hund, who was also an enthusiastic historian of science, distinguished themselves as physics teachers there but the university as a whole never recovered its international standing of before 1933 (see Figs. 1 and 2).
Protein-protein structure prediction by scoring molecular dynamics trajectories of putative poses.

PubMed

Sarti, Edoardo; Gladich, Ivan; Zamuner, Stefano; Correia, Bruno E; Laio, Alessandro

2016-09-01

The prediction of protein-protein interactions and their structural configuration remains a largely unsolved problem. Most of the algorithms aimed at finding the native conformation of a protein complex starting from the structure of its monomers are based on searching the structure corresponding to the global minimum of a suitable scoring function. However, protein complexes are often highly flexible, with mobile side chains and transient contacts due to thermal fluctuations. Flexibility can be neglected if one aims at finding quickly the approximate structure of the native complex, but may play a role in structure refinement, and in discriminating solutions characterized by similar scores. We here benchmark the capability of some state-of-the-art scoring functions (BACH-SixthSense, PIE/PISA and Rosetta) in discriminating finite-temperature ensembles of structures corresponding to the native state and to non-native configurations. We produce the ensembles by running thousands of molecular dynamics simulations in explicit solvent starting from poses generated by rigid docking and optimized in vacuum. We find that while Rosetta outperformed the other two scoring functions in scoring the structures in vacuum, BACH-SixthSense and PIE/PISA perform better in distinguishing near-native ensembles of structures generated by molecular dynamics in explicit solvent.

Incorporating expert judgments in utility evaluation of bacteroidales qPCR assays for microbial source tracking in a drinking water source.

2015-02-03

Several assays for the detection of host-specific genetic markers of the order Bacteroidales have been developed and used for microbial source tracking (MST) in environmental waters. It is recognized that the source-sensitivity and source-specificity are unknown and variable when introducing these assays in new geographic regions, which reduces their reliability and use. A Bayesian approach was developed to incorporate expert judgments with regional assay sensitivity and specificity assessments in a utility evaluation of a human and a ruminant-specific qPCR assay for MST in a drinking water source. Water samples from Lake Rådasjön were analyzed for E. coli, intestinal enterococci and somatic coliphages through cultivation and for human (BacH) and ruminant-specific (BacR) markers through qPCR assays. Expert judgments were collected regarding the probability of human and ruminant fecal contamination based on fecal indicator organism data and subjective information. Using Bayes formula, the conditional probability of a true human or ruminant fecal contamination given the presence of BacH or BacR was determined stochastically from expert judgments and regional qPCR assay performance, using Beta distributions to represent uncertainties. A web-based computational tool was developed for the procedure, which provides a measure of confidence to findings of host-specific markers and demonstrates the information value from these assays.

Hausväterliteratur designates works aimed at landlords and their wives in order to help them in the management of their estate. Among a wide-ranged list of topics tackled in these sizeable volumes, child welfare seldom fails to appear, though generally rather briefly. We consider in this paper a number of German works, most of them dating from the 17th century, though beginning with Johann Coler (1593) and winding up with Johann Joachim Becher (1714). These works include some advice on how to diagnose and manage the most common ailments, as well as some basic educational principles. A brief "pediatric" pharmacopoeia is often added. Although this review concerns only works in German, we have added references to a document taken from English literature, the diary of the clergyman and landlord Ralph Josselin. Dating from the same period (1643-1683), this document shows us how a landlord and his wife actually treated their sick children, thus shifting from theory to practice. "Hausväterliteratur" can be considered as an early stage of what was later termed "Domestic Medicine".

Vegetation and land carbon feedbacks in the high-resolution transient Holocene simulations using the MPI Earth system model

NASA Astrophysics Data System (ADS)

Brovkin, Victor; Lorenz, Stephan; Raddatz, Thomas

2017-04-01

Plants influence climate through changes in the land surface biophysics (albedo, transpiration) and concentrations of the atmospheric greenhouse gases. One of the interesting periods to investigate a climatic role of terrestrial biosphere is the Holocene, when, despite of the relatively steady global climate, the atmospheric CO2 grew by about 20 ppm from 7 kyr BP to pre-industrial. We use a new setup of the Max Planck Institute Earth System Model MPI-ESM1 consisting of the latest version of the atmospheric model ECHAM6, including the land surface model JSBACH3 with carbon cycle and vegetation dynamics, coupled to the ocean circulation model MPI-OM, which includes the HAMOCC model of ocean biogeochemistry. The model has been run for several simulations over the Holocene period of the last 8000 years under the forcing data sets of orbital insolation, atmospheric greenhouse gases, volcanic aerosols, solar irradiance and stratospheric ozone, as well as land-use changes. In response to this forcing, the land carbon storage increased by about 60 PgC between 8 and 4 kyr BP, stayed relatively constant until 2 kyr BP, and decreased by about 90 PgC by 1850 AD due to land use changes. Vegetation and soil carbon changes significantly affected atmospheric CO2 during the periods of strong volcanic eruptions. In response to the eruption-caused cooling, the land initially stores more carbon as respiration decreases, but then it releases even more carbon due to productivity decrease. This decadal- scale variability helps to quantify the vegetation and land carbon feedbacks during the past periods when the temporal resolution of the ice-core CO2 record is not sufficient to capture fast CO2 variations. From a set of Holocene simulations with prescribed or interactive atmospheric CO2, we get estimates of climate-carbon feedback useful for future climate studies.

Lung cancer screening guidelines recommend using individualized risk models to refer ever-smokers for screening. However, different models select different screening populations. The performance of each model in selecting ever-smokers for screening is unknown. To compare the U.S. screening populations selected by 9 lung cancer risk models (the Bach model; the Spitz model; the Liverpool Lung Project [LLP] model; the LLP Incidence Risk Model [LLPi]; the Hoggart model; the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial Model 2012 [PLCOM2012]; the Pittsburgh Predictor; the Lung Cancer Risk Assessment Tool [LCRAT]; and the Lung Cancer Death Risk Assessment Tool [LCDRAT]) and to examine their predictive performance in 2 cohorts. Population-based prospective studies. United States. Models selected U.S. screening populations by using data from the National Health Interview Survey from 2010 to 2012. Model performance was evaluated using data from 337 388 ever-smokers in the National Institutes of Health-AARP Diet and Health Study and 72 338 ever-smokers in the CPS-II (Cancer Prevention Study II) Nutrition Survey cohort. Model calibration (ratio of model-predicted to observed cases [expected-observed ratio]) and discrimination (area under the curve [AUC]). At a 5-year risk threshold of 2.0%, the models chose U.S. screening populations ranging from 7.6 million to 26 million ever-smokers. These disagreements occurred because, in both validation cohorts, 4 models (the Bach model, PLCOM2012, LCRAT, and LCDRAT) were well-calibrated (expected-observed ratio range, 0.92 to 1.12) and had higher AUCs (range, 0.75 to 0.79) than 5 models that generally overestimated risk (expected-observed ratio range, 0.83 to 3.69) and had lower AUCs (range, 0.62 to 0.75). The 4 best-performing models also had the highest sensitivity at a fixed specificity (and vice versa) and similar discrimination at a fixed risk threshold. These models showed better agreement on size of the

Concentration of nickel and chromium in any part of the ecosystem is important for environmental concerns in particular human health due to the reason that some species of them can cause health problem e.g. dermatitis and cancer. Sediment samples collected form a river Vordernberger Bach (Leoben, Austria) in an alpine region and soil samples collected in an area adjacent to steel production unit in same narrow valley were investigated. In previous studies a correlation between magnetic susceptibility values and concentration of nickel and chromium showed that a magnetic susceptibility meter can be used to point out the contaminated areas as in-situ device. The purpose of the whole study is to understand the real (point or diffuse, anthropogenic or geogenic) sources of contamination of soils, water and river sediments through heavy metal deposition. Unseparated, magnetic and non-magnetic fractions of soil samples were investigated for geochemical and mineralogical aspects with XRF, ICP-MS, EMPA, Multi-Functional Kappabridge (MFK1) and laser ablation coupled with ICP-MS. Mineralogical study of sediment samples for several sampling points with higher Ni and Cr content was performed. Sediment samples were sieved below 1.4 mm and then a concentrate of heavy minerals was prepared in the field through panning. Concentrated heavy minerals were then subjected for heavy liquid separation in the laboratory. Separated magnetic and non-magnetic fractions below 0.71/0.1 mm and density greater than 2.9 g/cm3 were selected for mineralogical investigation. The abundance of typical anthropogenic particles, e.g., spherical, tinder, roasted ores, iron and steel mill slag was observed under the microscope. Magnetite (mostly anthropogenic), maghemite, chromspinel, chromite (type I & II), (Ca,Al)-ferrite, wustite, apatite (anthropogenic), olivine mixed crystals, calcium silicate and spinel (anthropogenic) are found in magnetic fraction. Non-magnetic fractions contain hematite, siderite

Paeonol, a phenolic component from the root bark of Paeonia moutan, has been identified to possess antitumor effects. However, the effect of paeonol and the mechanism of CXCL4/CXCR3-B signals in paeonol-induced breast cancer cell remain unknown. After MDA-MB-231 cells were pretreated with paeonol or DMSO, the proliferation activity was detected by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide), Hoechst, Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL), and Annexin-V/propidium iodide staining flow cytometry. Western blot and immunohistochemistry of human breast cancer and noncancerous tissues were performed to determine the molecular alteration of CXCL4/CXCR3-B signals. Compared with the control, paeonol-treated breast cancer cells had low proliferation activity and high apoptotic index, indicating that paeonol induces breast cancer cell apoptosis. Western blot and immunohistochemistry showed that paeonol increased CXCR3-B signal, downregulated CXCL4, heme oxygenase (HO-1) with a corresponding increased BACH1, and decreased nuclear factor E2-related factor 2 (Nrf2). Thus, CXCL4/CXCR3-B may be involved in the mechanism of apoptosis induced by paeonol in breast cancer cells by regulating the expression of BACH1 and Nrf2 to downregulating HO-1 and promote apoptosis. Therefore, the authors suggest paeonol has a significant growth inhibitory effect on breast cancer cells, which may be related to the induction of apoptosis.

Enhancers regulate spatiotemporal gene expression and impart cell-specific transcriptional outputs that drive cell identity1. Stretch- or super-enhancers (SEs) are a subset of enhancers especially important for genes associated with cell identity and genetic risk of disease2,3,4,5,6. CD4+ T cells are critical for host defense and autoimmunity. Herein, we analyzed maps of T cell SEs as a non-biased means of identifying key regulatory nodes involved in cell specification. We found that cytokines and cytokine receptors were the dominant class of genes exhibiting SE architecture in T cells. This notwithstanding, the locus encoding Bach2, a key negative regulator of effector differentiation, emerged as the most prominent T cell SE, revealing a network wherein SE-associated genes critical for T cell biology are repressed by BACH2. Disease-associated SNPs for immune-mediated disorders, including rheumatoid arthritis (RA), were highly enriched for T cell-SEs versus typical enhancers (TEs) or SEs in other cell lineages7. Intriguingly, treatment of T cells with the Janus kinase (JAK) inhibitor, tofacitinib, disproportionately altered the expression of RA risk genes with SE structures. Together, these results indicate that genes with SE architecture in T cells encompass a variety of cytokines and cytokine receptors but are controlled by a “guardian” transcription factor, itself endowed with an SE. Thus, enumeration of SEs allows unbiased determination of key regulatory nodes in T cells, which are preferentially modulated by pharmacological intervention. PMID:25686607

Objective In addition to being prevalent and bothersome, urologic and sexual symptoms may be related to chronic medical illnesses. We investigate the relationship between ten urologic and sexual symptoms and four major illnesses (type II diabetes, cardiac disease, hypertension, and depression). Methods We analyze data from the Boston Area Community Health (BACH) Survey, a community-based epidemiologic study of urologic symptoms and risk factors. BACH used a two-stage stratified cluster sampling design to recruit 5,506 adults aged 30–79 (2,301 men, 3,205 women; 1,770 Black, 1,877 Hispanic, and 1,859 White respondents). Results In bivariate analyses, most urologic and sexual symptoms are associated with type II diabetes, cardiac disease, hypertension, and depression. However, in multivariate models adjusting for all four illnesses, gender, race/ethnicity, age, alcohol intake, smoking, physical activity, and body mass index there were fewer significant associations. We found that all urologic symptoms were significantly related to at least one illness, with depression increasing the odds of all urologic and sexual symptoms studied. Conclusions Urinary tract specialists may need to give greater weight to consideration of factors outside the urinary tract that may be contributing to urologic symptoms. It remains unknown whether treatment of medical and psychological illnesses can result in meaningful improvement in urologic symptoms, or conversely, whether urinary tract symptoms can provide valuable insight into an individual’s overall health status.

Listening to familiar music has recently been reported to be beneficial during recovery from stroke. A better understanding of changes in functional connectivity and information flow is warranted in order to further optimize and target this approach through music therapy. Twelve healthy volunteers listened to seven different auditory samples during an fMRI scanning session: a musical piece chosen by the volunteer that evokes a strong emotional response (referred to as: "self-selected emotional"), two unfamiliar music pieces (Invention #1 by J. S. Bach* and Gagaku - Japanese classical opera, referred to as "unfamiliar"), the Bach piece repeated with visual guidance (DML: Directed Music Listening) and three spoken language pieces (unfamiliar African click language, an excerpt of emotionally charged language, and an unemotional reading of a news bulletin). Functional connectivity and betweenness (BTW) maps, a measure for information flow, were created with a graph-theoretical approach. Distinct variation in functional connectivity was found for different music pieces consistently for all subjects. Largest brain areas were recruited for processing self-selected music with emotional attachment or culturally unfamiliar music. Maps of information flow correlated significantly with fMRI BOLD activation maps (p<0.05). Observed differences in BOLD activation and functional connectivity may help explain previously observed beneficial effects in stroke recovery, as increased blood flow to damaged brain areas stimulated by active engagement through music listening may have supported a state more conducive to therapy.

Theodor Billroth and Johannes Brahms shared a decades long personal friendship. The music-loving Billroth influenced the work of the famous composer and in turn Brahms also left traces within Billroth's lifetime achievements. To shed light on the close relationship of medicine and music, this manuscript describes both Billroth's life and surgical career as they were influenced and stimulated by his close friendship to Brahms.Theodor Billroth and Johannes Brahms first met in 1865 in Zurich, Switzerland. After Billroth accepted the chair of surgery at the University of Vienna in 1867, Brahms moved to Vienna in 1869. During the following years, Billroth analyzed most of Brahms' compositions prior to publication. Similar to his effective way of teaching medical students and assistants, Billroth stimulated Brahms to publish many of his later compositions. Brahms on the other hand supported Billroth in writing his essay"Who is musical?". Furthermore, music helped Billroth to cope with the demanding working life of a surgeon.Music and surgery share both structural and emotional analogies. While both professions require meticulous techniques, personal interaction is a prerequisite for success. "Science and art scoop from the same well."

By their very nature, comics communicate through a variety of visualization techniques. Benjamin Bach, who along with his coauthors Nathalie Henry Riche, Sheelagh Carpendale, and Hanspeter Pfister created this issue's Art on Graphics special contribution about the emerging genre of data comics, here talks about their attempts to leverage the massive untapped potential for data-driven comics to explain multiple threads of simultaneous data.

Comparing observed and synthetic seismograms, source amplitudes of NTS explosions are inferred from Rayleigh wave recordings from the WWSSN stations at Albuquerque, New Mexico (ALQ) and Tucson, Arizona (TUC). The potential influence of source complexities, particularly surface spallation and related phenomena, is studied in detail. As described in earlier work by Bache, Rodi and Harkrider, the earth model for the synthetic were converted from observations at ALQ and TUC. The agreement of observed and synthetic seismograms is quite good and is sensitive to important features of the source.

A system for using dice to compose music randomly is known as the musical dice game. The discrete time MIDI models of 804 pieces of classical music written by 29 composers have been encoded into the transition matrices and studied by Markov chains. Contrary to human languages, entropy dominates over redundancy, in the musical dice games based on the compositions of classical music. The maximum complexity is achieved on the blocks consisting of just a few notes (8 notes, for the musical dice games generated over Bach's compositions). First passage times to notes can be used to resolve tonality and feature a composer.

Development of a Hydrogen Møller Polarimeter for Precision Parity-Violating Electron Scattering

NASA Astrophysics Data System (ADS)

Gray, Valerie M.

2013-10-01

Parity-violating electron scattering experiments allow for testing the Standard Model at low energy accelerators. Future parity-violating electron scattering experiments, like the P2 experiment at the Johannes Gutenberg University, Mainz, Germany, and the MOLLER and SoLID experiments at Jefferson Lab will measure observables predicted by the Standard Model to high precision. In order to make these measurements, we will need to determine the polarization of the electron beam to sub-percent precision. The present way of measuring the polarization, with Møller scattering in iron foils or using Compton laser backscattering, will not easily be able to reach this precision. The novel Hydrogen Møller Polarimeter presents a non-invasive way to measure the electron polarization by scattering the electron beam off of atomic hydrogen gas polarized in a 7 Tesla solenoidal magnetic trap. This apparatus is expected to be operational by 2016 in Mainz. Currently, simulations of the polarimeter are used to develop the detection system at College of William & Mary, while the hydrogen trap and superconducting solenoid magnet are being developed at the Johannes Gutenberg University, Mainz. I will discuss the progress of the design and development of this novel polarimeter system. This material is based upon work supported by the National Science Foundation under Grant No. PHY-1206053.
Galileo's eye: a new vision of the senses in the work of Galileo Galilei.

PubMed

Piccolino, Marco; Wade, Nicholas J

2008-01-01

Reflections on the senses, and particularly on vision, permeate the writings of Galileo Galilei, one of the main protagonists of the scientific revolution. This aspect of his work has received scant attention by historians, in spite of its importance for his achievements in astronomy, and also for the significance in the innovative scientific methodology he fostered. Galileo's vision pursued a different path from the main stream of the then contemporary studies in the field; these were concerned with the dioptrics and anatomy of the eye, as elaborated mainly by Johannes Kepler and Christoph Scheiner. Galileo was more concerned with the phenomenology rather than with the mechanisms of the visual process. His general interest in the senses was psychological and philosophical; it reflected the fallacies and limits of the senses and the ways in which scientific knowledge of the world could be gathered from potentially deceptive appearances. Galileo's innovative conception of the relation between the senses and external reality contrasted with the classical tradition dominated by Aristotle; it paved the way for the modern understanding of sensory processing, culminating two centuries later in Johannes Müller's elaboration of the doctrine of specific nerve energies and in Helmholtz's general theory of perception.

The text of the Anatomical Institutions of Johann Guinter von Andernach, in its original version, was published almost simultaneously in Paris and Basel in 1536. Guinter was then in his fiftieth year, and Andreas Vesalius who was his student in Paris between 1533 ans 1536, was only twenty-two years old. His studies being finished in Leuven and his thesis being published for the first edition in Leuven in February 1537, and for the second in Basel in March 1537, Vesalius went to Padua where he was named professor of anatomy and surgery. Vesalius, besides the reasons put forward in his dedicatory lettre to Johann Armenterianus, tried to have rapidly printed documents for his students. He published in this way in April 1538 the engraved version of the great plates which he had mostly drawn and used to support his demonstrations during sessions of dissection. For the accompanying text, he choosed the handbook of his Master Guinter von Andernach which he decided to edit incorporating modifications and which he published in Venice in 1538 by D. Bernardinus. The modifications made by Vesalius on the Guinter's text can be classified in several headings: minor adjustments, additions of anatomical comments, additions corroborating traditional physiology, and anecdotes peppering the text.

Flin, Piotr

A review of the Large-scale structure of the Universe is given. A connection is made with the titanic work by Johannes Kepler in many areas of astronomy and cosmology. A special concern is made to spatial distribution of Galaxies, voids and walls (cellular structure of the Universe). Finaly, the author is concluding that the large scale structure of the Universe can be observed in much greater scale that it was thought twenty years ago.

[CNC proteins in physiology and pathology].

Gęgotek, Agnieszka; Skrzydlewska, Elżbieta

2015-07-06

CNC proteins consist of Bach1, Bach2 and 4 homologous transcription factors: Nrf1, Nrf2, Nrf3 and p45NF-E2. Transcription factors belonging to this group of proteins play a crucial role in protection of cells against oxidative stress. Under physiological conditions, they remain in the cytoplasm in the inactive form or are degraded. However, in oxidative stress conditions, they are translocated to the nucleus, and bind to DNA in the ARE sequence. Consequently, there is transcription of genes encoding cytoprotective proteins, such as phase II enzymes, or low molecular weight antioxidant proteins (i.e., thioredoxin, ferritin, metallothionein) responsible for protecting cells from reactive oxygen species (ROS) action. The activity of transcriptional proteins depends directly on the redox state of the cell. ROS as second messenger signals, control inhibitors of cytoplasmic CNC proteins or potentiate the activity of kinases (MAPK, PKC, PI3K, PERK), leading to phosphorylation of transcription factors. This is conducive to translocation of these molecules into the nucleus and to formation of complexes that initiate the gene expression. Disorders of regulation of the activity of transcription factors belonging to the CNC proteins caused by gene mutations, epigenetic modifications or increased activity of p62, p21, or k-Ras, B-Raf and c-Myc oncogenes, induce changes in the level of ARE-dependent gene expression, which can lead even to the development of carcinogenesis. On the other hand, Nrf transcription factors, inducing the expression of antioxidants and enzymes responsible for the detoxification of xenobiotics, can be considered as a potential target of the action of chemopreventive factors in anticancer therapy.

Johann Bernhard Aloys von Gudden and the Mad King of Bavaria

Bhattacharyya, Kalyan B.

2017-01-01

Bernhard von Gudden was a psychiatrist in Prussia and he was summoned in March 1886 to examine King Ludwig II for his apparently insane activities like, profligate spending and erratic behaviour. A team of four estimable psychiatrists pronounced that he was not capable ruling. Consequently, he was dethroned and kept in a castle under supervision of von Gudden. Gudden championed the idea of 'no restraint' and advocated free movement of insane persons and one evening in June, he accompanied the King during an evening stroll to a lake. A few hours later, the corpus of both of them were recovered under mysterious circumstances. Autopsy suggested that the King was drowned but no post-mortem examination was performed on von Gudden. There are plenty of controversies regarding their death like, murder, accidental death or even natural death from cardiac arrest following immersion in cold water, but no incontrovertible conclusion could be arrived at, even after scrupulous analysis by historians and even the diagnosis of insanity of the King has been doubted. Some even suggested that the opinion of psychiatrists were sought as a pretense in order to depose the King. PMID:29184335
The history and illustration of anatomy in the Middle Ages.

Gurunluoglu, Raffi; Gurunluoglu, Aslin; Williams, Susan A; Cavdar, Safiye

2013-11-01

This article reviews the influence of key figures on the pictorial representation of anatomy and the evolution of anatomical illustration during the Middle Ages until the time of the Renaissance, based on medical history books, journals and ancient medical books. During the early period in the Middle Ages, most illustrations were traditional drawings of emblematic nature, oftentimes unrealistic, not only because the precise knowledge of anatomy was lacking but also because the objective was to elucidate certain principles for teaching purposes. Five figure-series that came down to us through ancient manuscripts and textbooks represent the best examples of such traditional illustrations. With the advent of human dissection in the 13th and 14th centuries, a significant transformation in the depiction of anatomy began to project the practice of human dissection, as we see in the works of Mondino de Luzzi, Henri de Mondeville and Guido de Vigevano. After the invention of book printing in the second half of the 15th century, the reproduction of books was commonly practised and the woodcut made multiplication of pictures easier. Peter of Abano, Hieronymous Brunschwig, Johannes de Ketham, Johannes Peyligk, Gregory Reisch, Magnus Hundt, Laurentius Phryesen and many more included several anatomical illustrations in their treatises that demonstrated the development of anatomical illustration during the later Middle Ages.
Spatially resolved high resolution x-ray spectroscopy for magnetically confined fusion plasmas (invited)

2008-10-15

The use of high resolution x-ray crystal spectrometers to diagnose fusion plasmas has been limited by the poor spatial localization associated with chord integrated measurements. Taking advantage of a new x-ray imaging spectrometer concept [M. Bitter et al., Rev. Sci. Instrum. 75, 3660 (2004)], and improvements in x-ray detector technology [Ch. Broennimann et al., J. Synchrotron Radiat. 13, 120 (2006)], a spatially resolving high resolution x-ray spectrometer has been built and installed on the Alcator C-Mod tokamak. This instrument utilizes a spherically bent quartz crystal and a set of two dimensional x-ray detectors arranged in the Johann configuration [H. H.more » Johann, Z. Phys. 69, 185 (1931)] to image the entire plasma cross section with a spatial resolution of about 1 cm. The spectrometer was designed to measure line emission from H-like and He-like argon in the wavelength range 3.7 and 4.0 A with a resolving power of approximately 10 000 at frame rates up to 200 Hz. Using spectral tomographic techniques [I. Condrea, Phys. Plasmas 11, 2427 (2004)] the line integrated spectra can be inverted to infer profiles of impurity emissivity, velocity, and temperature. From these quantities it is then possible to calculate impurity density and electron temperature profiles. An overview of the instrument, analysis techniques, and example profiles are presented.« less

The camera obscura (from Latin meaning darkened chamber) is a simple optical device with a long history. In the form considered here, it can be traced back to 1550. It had its heyday during the Victorian era when it was to be found at the seaside as a tourist attraction or sideshow. It was also used as an artist's drawing aid and, in 1620, the famous astronomer-mathematician, Johannes Kepler used a small tent camera obscura to trace the scenery.

Biological Sulfate Reduction Rates in Hydrothermal Recharge Zones

NASA Astrophysics Data System (ADS)

Crowell, B.; Lowell, R. P.

2007-12-01

We develop a model to determine the rate of removal of seawater sulfate in the recharge regions of deep-sea hydrothermal systems as a result of biogenic sulfate reduction. The rate of sulfate reduction as a function of temperature derived from laboratory measurements on cores from the Guaymas Basin in Mexico [Jorgensen et al., 1992] is incorporated into a steady state 1-D advection-diffusion temperature equation, and a 1-D, steady- state, advection dominated conservation of solute equation. The diffusivity of sulfate in seawater is on the order of ~ 10-10 m2/s, and unless the flow speeds are < 10-12 m/s, the effects of diffusion are negligible, except within thin diffusive boundary layers. This model is then compared with a model that utilizes Gibbs free energy to quantify biogenic sulfate reduction [Bach and Edwards, 2003] in the upper oceanic crust of aging lithosphere. Using the high rates determined by Jorgensen et al. [1992], our model indicates that biological activity would reduce all seawater sulfate transported into the system within the upper 10 meters or less of the crust, which is inconsistent with the estimates of Bach and Edwards [2003]. Sulfate concentrations from ODP borehole Legs 64 and 168, at the sedimented Guaymas Basin and Juan de Fuca Ridge, respectively, show that most of the seawater sulfate is removed in the upper 100 meters. If the sulfate is assumed to all be reduced biogenically, the sulfate reduction rates at the ODP sites are at least 2 orders of magnitude less than the laboratory estimates of Jorgenson et al. [1992]. Finally, we compare the rate of seawater sulfate removal as a result of the precipitation of anhydrite, with the rate of biogenic sulfate reduction. We find that if hydrothermal recharge occurs rapidly through highly permeable faults, that biogenic sulfate reduction is negligible and that anhydrite precipitation would rapidly clog the recharge zone [Lowell and Yao, 2002]. If recharge occurs through broad zones of slow
Musical rhythm spectra from Bach to Joplin obey a 1/f power law.

PubMed

Levitin, Daniel J; Chordia, Parag; Menon, Vinod

2012-03-06

Much of our enjoyment of music comes from its balance of predictability and surprise. Musical pitch fluctuations follow a 1/f power law that precisely achieves this balance. Musical rhythms, especially those of Western classical music, are considered highly regular and predictable, and this predictability has been hypothesized to underlie rhythm's contribution to our enjoyment of music. Are musical rhythms indeed entirely predictable and how do they vary with genre and composer? To answer this question, we analyzed the rhythm spectra of 1,788 movements from 558 compositions of Western classical music. We found that an overwhelming majority of rhythms obeyed a 1/f(β) power law across 16 subgenres and 40 composers, with β ranging from ∼0.5-1. Notably, classical composers, whose compositions are known to exhibit nearly identical 1/f pitch spectra, demonstrated distinctive 1/f rhythm spectra: Beethoven's rhythms were among the most predictable, and Mozart's among the least. Our finding of the ubiquity of 1/f rhythm spectra in compositions spanning nearly four centuries demonstrates that, as with musical pitch, musical rhythms also exhibit a balance of predictability and surprise that could contribute in a fundamental way to our aesthetic experience of music. Although music compositions are intended to be performed, the fact that the notated rhythms follow a 1/f spectrum indicates that such structure is no mere artifact of performance or perception, but rather, exists within the written composition before the music is performed. Furthermore, composers systematically manipulate (consciously or otherwise) the predictability in 1/f rhythms to give their compositions unique identities.

Planform changes and large wood dynamics in two torrents during a severe flash flood in Braunsbach, Germany 2016.

This work presents a post-event survey study, addressing the geomorphic response and large wood budget of two torrents, Grimmbach and Orlacher Bach, in southwestern Germany that were affected by a flash flood on May 29, 2016. During the event, large amounts of wood clogged and damaged a bridge of a cycling path at the outlet of the Grimmbach, while the town of Braunsbach was devastated by discharge and material transported along the Orlacher Bach. The severity of the event in these two small catchments (30.0 km 2 and 5.95 km 2 , respectively) is remarkable in basins with a relatively low average slope (10.7 and 12.0%, respectively). In order to gain a better understanding of the driving forces during this flood event an integrated approach was applied including (i) an estimate of peak discharges, (ii) an analysis of changes in channel width by comparing available aerial photographs before the flood with a post-flood aerial surveys with an Unmanned Aerial Vehicle and validation with field observations, (iii) a detailed mapping of landslides and analysis of their connectivity with the channel network and finally (iv) an analysis of the amounts of large wood recruited and deposited in the channel. The morphological changes in the channels can be explained by hydraulic parameters, such as stream power and unit stream power, and by morphological parameters such as the valley confinement. This is similar for LW recruitment amounts and volume of exported LW since most of it comes from the erosion of the valley floor. The morphological changes and large wood recruitment and deposit are in the range of studied mountain rivers. Both factors thus need to be considered for mapping and mitigating flash flood hazards also in this kind of low range mountains. Copyright © 2018 The Authors. Published by Elsevier B.V.

Repeated object loss drove Sylvia Plath to create, and what she created were her greatest, and best-known poems, collected in the book Ariel. Yet the compulsion to create alternated with the compulsion to destroy. Her suicidal impulses were as intense as her poetic impulses (see Bach, 1985, on the "Marquis de Sade"). How these two contrasting impulses counter-balanced each other, until self-destruction took the lead, is the story of Sylvia Plath. What remains with us is the puzzle of her despair. This puzzle can only be pieced together by looking at the internal object relations of the father-daughter bond, which germinated like a ghost and spector within Sylvia Plath's soul.

We present facsimiles of some of the scientifically and historically most relevant papers published in Astronomische Nachrichten/Astronomical Notes (AN) between 1821 and 1938. Almost all of these papers were written and printed in German and it is sometimes not completely straightforward to find these original works and then to cite the historically correct version, e.g. in case of a series of articles or editorial letters. It was common during the early years that many contributions were made in form of letters to the editor. We present a summary for these original works with an English translation of their titles. Among the highlights are the originals of the discovery of stellar parallaxes by Friedrich Wilhelm Bessel, the discovery of the solar cycle by Heinrich Schwabe, the discovery of the planet Neptune by Johann Gottfried Galle, the first ever measured stellar radial velocity by Hermann Vogel, the discovery of radio emission from the Sun by Wilsing and Scheiner, the first ever conducted photoelectric photometry of stars by Paul Guthnick and up to the pioneering work by Karl Schwarzschild, Ejnar Hertzsprung, Erwin Finlay Freundlich and others. As a particular gimmick we present the still world record holding shortest paper ever published; by Johannes Hartmann in AN 226, 63 (1926) on Nova Pictoris. Our focus is on contributions in the early years and published until 1938 near the verge of the second world war.

Of course, all this is absurd. In the author's view, the true discoverers of Neptune were Johann Gottfried Galle and Heinrich D'Arrest.

The term stimulus, as it was used in science from its earliest appearance in the sixteenth century up to the beginning of the nineteenth century, shows a gradual progress in denotation from the physical object designed to produce nervous and muscular excitation to the generically conceived event or object that initiates sensory or motor activity. To this shift corresponds a shift in the understanding of sensory experience. Johannes Muller's law of specific energy of sensory nerves played a major role in the shift, and Hermann von Helmholtz gave the shift its most thorough philosophical explanation.

All that glitters: fool's gold in the early-modern era.

PubMed

Roos, Anna Marie

2008-12-01

Natural philosophers of the early-modern period perceived fool's gold or iron pyrites as a substance required for the formation of metals, and chemists such as Johann Glauber speculated the vitriol produced from pyrites was the source of the legendary philosopher's stone. The sulphurous exhalations of fool's gold were also thought by members of the early Royal Society to be the basis of a variety of meteorological, geological and medical effects, including the production of thunder, lightning, earthquakes and volcanoes, fossilisation and petrifaction, as well as the principal cause of bladder and gallstones.
Field-modulation spectroscopy of pentacene thin films using field-effect devices: Reconsideration of the excitonic structure

Haas, Simon; Matsui, Hiroyuki; Hasegawa, Tatsuo

2010-10-01

We report pure electric-field effects on the excitonic absorbance of pentacene thin films as measured by unipolar field-effect devices that allowed us to separate the charge accumulation effects. The field-modulated spectra between 1.8 and 2.6 eV can be well fitted with the first derivative curve of Frenkel exciton absorption and its vibronic progression, and at higher energy a field-induced feature appears at around 2.95 eV. The results are in sharp contrast to the electroabsorption spectra reported by Sebastian in previous studies [Chem. Phys. 61, 125 (1981)10.1016/0301-0104(81)85055-0], and leads us to reconsider the excitonic structure including the location of charge-transfer excitons. Nonlinear π -electronic response is discussed based on second-order electro-optic (Kerr) spectra.
Alchemy, Prophecy, and Politics in Eighteenth-Century Iberia: Anselmo Castelo Branco's Critique of Benito Feijoo.

PubMed

Leitão, José Vieira

2016-11-01

The Benedictine monk Benito Jerónimo Feijoo (1676-1764) is now considered one of the major figures of the Spanish and Iberian Enlightenment. However his work, both in Spain and in Portugal, was far from being universally acclaimed. His critical approach to the subject of alchemy in his essay "Piedra Filosofal," published in the third volume of his magisterial Teatro Crítico Universal (1726-1739), sparked an unexpected response from the Portuguese alchemist Anselmo Castelo Branco, who sought to refute Feijoo's claims in his own work, the Ennoea. This paper presents an outline of this exchange and its position within Iberian Enlightenment circles. It further argues that Castelo Branco's defence of alchemy was informed by his political and prophetic views, in particular his adherence to the Portuguese messianic doctrine of Sebastianism.

Stable photon orbits in stationary axisymmetric electrovacuum spacetimes

Dolan, Sam R.; Shipley, Jake O.

2016-08-01

We investigate the existence and phenomenology of stable photon orbits (SPOs) in stationary axisymmetric electrovacuum spacetimes in four dimensions. First, we review the classification of equatorial circular photon orbits on Kerr-Newman spacetimes in the charge-spin plane. Second, using a Hamiltonian formulation, we show that Reissner-Nordström diholes (a family encompassing the Majumdar-Papapetrou and Weyl-Bach special cases) admit SPOs, in a certain parameter regime that we investigate. Third, we explore the transition from order to chaos for typical SPOs bounded within a toroidal region around a dihole, via a selection of Poincaré sections. Finally, for general axisymmetric stationary spacetimes, we show that the Einstein-Maxwell field equations allow for the existence of SPOs in electro vacuum, but not in pure vacuum.
Perception-action relationships reconsidered in light of spatial display instruments

Spatial display instruments convey information about both the identity and the location of objects in order to assist surgeons, astronauts, pilots, blind individuals, and others in identification, remote manipulations, navigation, and obstacle avoidance. Scientists believe that these instruments have not reached their full potential and that progress toward new applications, including the possibility of restoring sight to the blind, will be accelerated by advancing the understanding of perceptual processes. This stimulating challenge to basic researchers was advanced by Paul Bach-Y-Rita (1972) and by the National Academy of Science (1986) report on Electronic Aids for the Blind. Although progress has been made, new applications of spatial display instruments in medicine, space, aviation, and rehabilitation await improved theoretical and empirical foundations.

The first clinical experiment is described in the bible: The prophet Daniel is reported being nourished during ten days by seeds and water only, in order to check if his physical state would deteriorate as a result of this minimal nutrition. In the 15th century, French surgeon Ambroise Parí experimented with a mixture of turpentine, egg protein and rose oil to treat combat wounds, which is thought to be the first clinical study to be reported. In the 19th century British scientist James Lind designed the first controlled prospective study with parallel groups, proving that ingesting citrus fruit prevents scurvy. A short time afterwards British scientist John Haygarth was the first to use a placebo drug in a clinical study. Important work on placebo was conducted by the American scientists Austin Flint and later by Henry K. Beecher, who showed that placebo itself has biological properties. The importance of comparative studies was first understood by French psychologist CLaude Bernard. He is considered the founder of the modern scientific method based on observation, analysis of data and examination of hypotheses. Bernard's work was based on the work of fellow Frenchman Pierre Charles Alexandre Louis, who is justly considered a founding father of modern epidemiology, and who was the first to use statistics in clinical experiments. Random distributions in clinical studies were reported even before this time, for instance in the work of the Flemish physician Johannes Baptista van Helmont. Danish Nobel prize winner Johannes Fibiger pioneered the use of selection bias in his work with diphtheria serum.

Landgrave Wilhelm IV established in 1560 the first permanent astronomical observatory in Europe. When he met the young Tycho Brahe in 1575 he recognized the genius and recommended him warmly to the Danish king Frederik II. Wilhelm and Tycho must share the credit for renewing astronomy with very accurate observations of positions of stars by new instrumentation and new methods. Tycho's observations of planets during 20 years enabled Johannes Kepler to derive the laws of planetary motion. These laws set Isaac Newton in a position to publish the laws of physical motion and universal gravitation in 1687 - the basis for the technical revolution.
Preliminary evaluation of adhesion strength measurement devices for ceramic/titanium matrix composite bonds

NASA Technical Reports Server (NTRS)

Pohlchuck, Bobby; Zeller, Mary V.

1992-01-01

The adhesive bond between ceramic cement and a titanium matrix composite substrate to be used in the National Aerospace Plane program is evaluated. Two commercially available adhesion testers, the Sebastian Adherence Tester and the CSEM REVETEST Scratch Tester, are evaluated to determine their suitability for quantitatively measuring adhesion strength. Various thicknesses of cements are applied to several substrates, and bond strengths are determined with both testers. The Sabastian Adherence Tester has provided limited data due to an interference from the sample mounting procedure, and has been shown to be incapable of distinguishing adhesion strength from tensile and shear properties of the cement itself. The data from the scratch tester has been found to be difficult to interpret due to the porosity and hardness of the cement. Recommendations are proposed for a more reliable adhesion test method.

Motivation: Data compression is crucial in effective handling of genomic data. Among several recently published algorithms, ERGC seems to be surprisingly good, easily beating all of the competitors. Results: We evaluated ERGC and the previously proposed algorithms GDC and iDoComp, which are the ones used in the original paper for comparison, on a wide data set including 12 assemblies of human genome (instead of only four of them in the original paper). ERGC wins only when one of the genomes (referential or target) contains mixed-cased letters (which is the case for only the two Korean genomes). In all other cases ERGC is on average an order of magnitude worse than GDC and iDoComp.

This report summarizes the 1991 water-use reporting through the Conservation District Offices in the following west-central Arkansas counties: Conway, Crawford, Faulkner, Franklin, Johnson, Logan, Perry, Pope, Scott, Sebastian, and Yell. The number of withdrawal registrations for west-central Arkansas counties was 307 (90 groundwater and 217 surface water). Water withdrawals reported during the registration process total 1.00 Mgal/d (0.15 Mgal/d groundwater and 0.85 Mgal/d surface water) for agriculture and 32.07 Mgal/d (5.67 Mgal/d groundwater and 26.40 Mgal/d surface water) for irrigation. The registration reports for 1991 indicate that this water was applied to 22,856 acres of land to irrigate rice, corn, sorghum, soybeans, wheat, cash grains, hay, milo, vegetables, sod, berries, grapes, and fruit trees as well as for the agricultural uses of catfish and ducks.

Female urinary incontinence is prevalent, costly and morbid. Participants in a NIDDK (National Institute of Diabetes and Digestive and Kidney Diseases) sponsored summit reviewed findings from NIH (National Institutes of Health) funded clinical research on urinary incontinence in women and discussed the future of urinary incontinence research. The NIDDK convened the Summit on Urinary Incontinence Clinical Research in Women on March 14, 2014. Participants representing a broad range of clinical expertise reviewed completed NIH sponsored urinary incontinence related studies, including results from community based epidemiological studies such as the BACH (Boston Area Community Health) Survey and from randomized clinical trials such as PRIDE (Program to Reduce Incontinence by Diet and Exercise), and studies conducted by the Pelvic Floor Disorders Network and the Urinary Incontinence Treatment Network. BACH Survey results improved our understanding of precursors, incidence, prevalence and natural history of urinary incontinence in a diverse group of women. The Pelvic Floor Disorders Network study found that anticholinergic medications and onabotulinumtoxinA are efficacious for treating urge urinary incontinence, and Burch colposuspension and retropubic mid urethral polypropylene slings are efficacious for decreasing stress urinary incontinence following pelvic organ prolapse surgery in women with potential stress urinary incontinence. The Urinary Incontinence Treatment Network study found that fascial slings were better than colposuspension, and that retropubic and transobturator mid urethral polypropylene slings were equivalent for stress urinary incontinence. In patients with stress urinary incontinence a preoperative urodynamic study was noninferior to basic office examinations for surgical outcome. The addition of behavioral intervention did not allow female patients to discontinue antimuscarinics for urge urinary incontinence. PRIDE showed that modest weight
The miR-23a~27a~24-2 microRNA cluster buffers transcription and signaling pathways during hematopoiesis

MicroRNA cluster mirn23a has previously been shown to promote myeloid development at the expense of lymphoid development in overexpression and knockout mouse models. This polarization is observed early in hematopoietic development, with an increase in common lymphoid progenitors (CLPs) and a decrease in all myeloid progenitor subsets in adult bone marrow. The pool size of multipotential progenitors (MPPs) is unchanged; however, in this report we observe by flow cytometry that polarized subsets of MPPs are changed in the absence of mirn23a. Additionally, in vitro culture of MPPs and sorted MPP transplants showed that these cells have decreased myeloid and increased lymphoid potential in vitro and in vivo. We investigated the mechanism by which mirn23a regulates hematopoietic differentiation and observed that mirn23a promotes myeloid development of hematopoietic progenitors through regulation of hematopoietic transcription factors and signaling pathways. Early transcription factors that direct the commitment of MPPs to CLPs (Ikzf1, Runx1, Satb1, Bach1 and Bach2) are increased in the absence of mirn23a miRNAs as well as factors that commit the CLP to the B cell lineage (FoxO1, Ebf1, and Pax5). Mirn23a appears to buffer transcription factor levels so that they do not stochastically reach a threshold level to direct differentiation. Intriguingly, mirn23a also inversely regulates the PI3 kinase (PI3K)/Akt and BMP/Smad signaling pathways. Pharmacological inhibitor studies, coupled with dominant active/dominant negative biochemical experiments, show that both signaling pathways are critical to mirn23a’s regulation of hematopoietic differentiation. Lastly, consistent with mirn23a being a physiological inhibitor of B cell development, we observed that the essential B cell transcription factor EBF1 represses expression of mirn23a. In summary, our data demonstrates that mirn23a regulates a complex array of transcription and signaling pathways to modulate adult hematopoiesis

Conference banner The Joint European Magnetic Symposia JEMS 2010 took place in the complex Auditorium Maximum of the Jagiellonian University in Kraków, Poland, between 23-28 August 2010. It followed the series of the conferences in Grenoble (2001), Dresden (2004), San Sebastian (2006), and Dublin (2008). The next Symposia will be held in 2012 in Parma (Italy). The Symposia cover a broad range of aspects of magnetism and magnetic materials, as well as providing a forum for the magnetism community to discuss new concepts, properties, and developments in all branches of fundamental and applied magnetism. The JEMS 2010 Symposia were organized by the Institute of Physics of Jagiellonian University, in cooperation with AGH University of Science and Technology (Kraków), Cracow University of Technology, Institute of Nuclear Physics of the Polish Academy of Sciences in Kraków, and the Silesian University in Katowice. I thank the Local Committee, and in particular Professor Krzysztof Tomala, for their hard work long before, during, and after the Conference. We dedicate this volume to Professor Henryk Szymczak from the Institute of Physics of the Polish Academy of Sciences for his long lasting service to the magnetism community and the organizational effort in bringing this Conference to our community. Thank you Henryk! The Conference contained Plenary Sessions and 16 Symposia, which are listed below. Most of them had two chairpersons (also listed), one from abroad and one from Poland. I believe that a collective chairmanship of the Symposia is very helpful in both their organization, as well as in the reviewing process of the papers submitted to the Conference Proceedings. I would like to cordially thank all the persons listed below, who have contributed enormously to the success of our meeting. The Proceedings comprises 116 invited and contributed papers.

The history of medical and veterinary mycology in general has been reviewed in the excellent monography by G.C. Ainsworth (1905-1998) published in 1986. Here, we will focus on German-speaking mycology and their outstanding personalities. We will start with the early years when medical mycology was in its infancy. Microscopy was a most valuable tool for the identification of fungi followed by cultivation and staining methods. Human pathologies became linked to fungi. After World War I, medical mycology flourished as an integral part of dermatology at universities and in private institutes. The development was interrupted by World War II, which divided Germany. In both parts of Germany, medical mycology had to be re-established. After re-unification the two different medical societies joined together. The development of DMyK (Deutschsprachigen Mykologischen Gesellschaft - Mykologie) is illustrated. Important personalities and some of their achievements are mentioned. Mycology has attracted other fields of medicine including internal medicine, pediatrics, microbiology, and veterinary medicine.

Ultra-wideline 137Ba solid-state (SS) NMR spectra have been obtained from a series of five barium compounds (BaSO4, BaMoO4, Ba(CH3COO)2, Ba(OH)2·8H2O and α-Ba2P2O7), using the broadband WURST-QCPMG pulse sequence and magnetic field of 21.1 T. The signals from the two distinct crystallographic sites in α-Ba2P2O7 are resolved, with one of them demonstrating a CQ of 42.3 ± 0.3 MHz, the largest obtained for 137Ba in a powder. The quadrupolar parameters reported in this work are in excellent agreement with the DFT calculations and correlate well with those previously reported by Hamaed et al. (2010) [24].

Facial reconstruction--anatomical art or artistic anatomy?

Wilkinson, Caroline

2010-02-01

Facial reconstruction is employed in the context of forensic investigation and for creating three-dimensional portraits of people from the past, from ancient Egyptian mummies and bog bodies to digital animations of J. S. Bach. This paper considers a facial reconstruction method (commonly known as the Manchester method) associated with the depiction and identification of the deceased from skeletal remains. Issues of artistic licence and scientific rigour, in relation to soft tissue reconstruction, anatomical variation and skeletal assessment, are discussed. The need for artistic interpretation is greatest where only skeletal material is available, particularly for the morphology of the ears and mouth, and with the skin for an ageing adult. The greatest accuracy is possible when information is available from preserved soft tissue, from a portrait, or from a pathological condition or healed injury.

The Greek physician Hippocrates (c. 460-377 BC) is traditionally regarded as the founder of medicine as a scientific discipline and medical ethics. Hippocrates sought to rely on facts, observation and experiment in the diagnosis and treatment of illness. His work Corpus Hippocraticum included also the remarques on the aspects of environmental medicine. Albert Schweitzer (1875-1965), recipient of the 1952 Nobel Peace Prize, attained fame as a theologian and musician (his activity included a modern interpretation of J.S. Bach) before turning to missionary work in Africa. Having trained as a physician in Strasbourg, he founded (1913) a hospital at Lambarene, Gabon, to which he dedicated the rest of his life. Early in his life he felt deep "reverence for life". His philosophy culminated in an universal affirmative ethnics of an active charity.

In particular, using methods of dispersive PDEs similar to the ones used in Grillakis and Machedon (Commun Partial Differ Equ 42:24-67, 2017), we are able to show for any scaling parameter β >0 the TDHFB equations are globally well-posed in some Strichartz-type spaces independent of N, cf.

The Two Subduction Zones of the Southern Caribbean: Lithosphere Tearing and Continental Margin Recycling in the East, Flat Slab Subduction and Laramide-Style Uplifts in the West

The southern Caribbean plate boundary is a complex strike-slip fault system bounded by oppositely vergent subduction zones, the Antilles subduction zone in the east, and a currently locked Caribbean-South American subduction zone in the west (Bilham and Mencin, 2013). Finite-frequency teleseismic P-wave tomography images both the Atlanic (ATL) and the Caribbean (CAR) plates subducting steeply in opposite directions to transition zone depths under northern South America. Ps receiver functions show a depressed 660 discontinuity and thickened transition zone associated with each subducting plate. In the east the oceanic (ATL) part of the South American (SA) plate subducts westward beneath the CAR, initiating the El Pilar-San Sebastian strike slip system, a subduction-transform edge propagator (STEP) fault (Govers and Wortel, 2005). The point at which the ATL tears away from SA as it descends into the mantle is evidenced by the Paria cluster seismicity at depths of 60-110 km (Russo et al, 1993). Body wave tomography and lithosphere-asthenosphere boundary (LAB) thickness determined from Sp and Ps receiver functions and Rayleigh waves suggest that the descending ATL also viscously removes the bottom third to half of the SA continental margin lithospheric mantle as it descends. This has left thinned continental lithosphere under northern SA in the wake of the eastward migrating Antilles subduction zone. The thinned lithosphere occupies ~70% of the length of the El Pilar-San Sebastian fault system, from ~64oW to ~69oW, and extends inland several hundred kilometers. In northwestern SA the CAR subducts east-southeast at low angle under northern Colombia and western Venezuela. The subducting CAR is at least 200 km wide, extending from northernmost Colombia as far south as the Bucaramanga nest seismicity. The CAR descends steeply under Lake Maracaibo and the Merida Andes. This flat slab is associated with three Neogene basement cored, Laramide-style uplifts: the Santa Marta

Professor Robertson sketches an elegant framework for policy evaluation and regulation of the use of preimplantation genetic diagnosis for various medical, medical related, and non-medical purposes. In criticism of his position, I argue that the distinction between policy and ethics upon which his argument relies is highly unstable, and the approach taken to ethical evaluation of particular parental interests leaves open many issues which the policy approach would hope to exclude. In conclusion I argue that while his position ultimately fails, the onus is on his critics to come up with a viable and satisfying alternative.

Johann Wolfgang von Goethe was one of the most renowned German poets of the late Age of Enlightenment. However, his engagement went far beyond literature especially relating to politics and natural science. Goethe, primarily trained as a lawyer, developed his own theory of colors and even challenged the concepts of Isaac Newton. His discovery of the human intermaxilary bone questioned all the dogmas of the religious-minded world of the 18th century. Together with the anatomy professor Justus Christian Loder, Goethe performed comparative anatomy and proved the conceptual uniformity of humans and animals on 27 March 1784. Even though, Félix Vicq d'Azyr described the intermaxilary bone simultaneously in Catholic France, Goethe's findings were politically accepted due to the liberal Protestantism of the Duchy of Weimar. Nevertheless, leading anatomists of the century (Johann Friedrich Blumenbach, Petrus Camper and Samuel Thomas v. Soemmerring) mainly rejected Goethe's postulates which led to a delayed publication in 1820; almost 36 years after writing his original manuscript. Today, Goethe's discovery is known to be a fundamental basis for the development of Charles Darwin's theory of phylogenetic evolution. Nowadays, the Department of Anatomy contains the Museum Anatomicum Jenense which was founded by the Duke of Weimar, Carl August and Goethe and entails Goethe's premaxillary bones as its main attraction.

This work discusses several selected topics of plant genetics and breeding in relation to the 150th anniversary of the seminal work of Gregor Johann Mendel. In 2015, we celebrated the 150th anniversary of the presentation of the seminal work of Gregor Johann Mendel. While Darwin's theory of evolution was based on differential survival and differential reproductive success, Mendel's theory of heredity relies on equality and stability throughout all stages of the life cycle. Darwin's concepts were continuous variation and "soft" heredity; Mendel espoused discontinuous variation and "hard" heredity. Thus, the combination of Mendelian genetics with Darwin's theory of natural selection was the process that resulted in the modern synthesis of evolutionary biology. Although biology, genetics, and genomics have been revolutionized in recent years, modern genetics will forever rely on simple principles founded on pea breeding using seven single gene characters. Purposeful use of mutants to study gene function is one of the essential tools of modern genetics. Today, over 100 plant species genomes have been sequenced. Mapping populations and their use in segregation of molecular markers and marker-trait association to map and isolate genes, were developed on the basis of Mendel's work. Genome-wide or genomic selection is a recent approach for the development of improved breeding lines. The analysis of complex traits has been enhanced by high-throughput phenotyping and developments in statistical and modeling methods for the analysis of phenotypic data. Introgression of novel alleles from landraces and wild relatives widens genetic diversity and improves traits; transgenic methodologies allow for the introduction of novel genes from diverse sources, and gene editing approaches offer possibilities to manipulate gene in a precise manner.

Sentiment analysis (also known as opinion mining) refers to the use of text analysis and computational linguistics to identify and extract subjective information in source materials. Sentiment analysis is widely applied to reviews discussion that is being talked in social media for many purposes, ranging from marketing, customer service, or public opinion of public policy. One of the popular algorithm for Sentiment Analysis implementation is Kumar algorithm that developed by Kumar and Sebastian. Kumar algorithm can identify the sentiment score of the statement, sentence or tweet, but cannot determine the relationship of the object or target related to the sentiment being analysed. This research proposed solution for that challenge by adding additional component that represent object or target to the existing algorithm (Kumar algorithm). The result of this research is a modified algorithm that can give sentiment score based on a given object or target.

Currently, the May-Hegglin anomaly (MHA), Sebastian (SBS), Fechtner (FTNS) and Epstein (EPS) syndrome are considered to be distinct clinical manifestations of a single disease caused by mutations of the MYH9 gene encoding the heavy chain of non-muscle myosin IIA (NMMHC-IIA). Manifestations of these disorders include giant platelets, thrombocytopenia and combinations of the presence of granulocyte inclusions, deafness, cataracts and renal failure. We examined 15 patients from 10 unrelated families on whom we performed immunostaining of NMMHC-IIA in blood samples. Polymerase chain reaction (PCR) analysis of selected exons of the MYH9 gene revealed mutations in nine samples with one novel mutation. Results of fluorescence and mutational analysis were compared with clinical manifestations of the MYH9 disorder. We also determined the number of glycoprotein sites on the surface of platelets. Most patients had an increased number of glycoproteins, which could be due to platelet size.

Data compression is crucial in effective handling of genomic data. Among several recently published algorithms, ERGC seems to be surprisingly good, easily beating all of the competitors. We evaluated ERGC and the previously proposed algorithms GDC and iDoComp, which are the ones used in the original paper for comparison, on a wide data set including 12 assemblies of human genome (instead of only four of them in the original paper). ERGC wins only when one of the genomes (referential or target) contains mixed-cased letters (which is the case for only the two Korean genomes). In all other cases ERGC is on average an order of magnitude worse than GDC and iDoComp. sebastian.deorowicz@polsl.pl, iochoa@stanford.edu Supplementary data are available at Bioinformatics online. © The Author 2015.

Diffusing diffusivity: Rotational diffusion in two and three dimensions

NASA Astrophysics Data System (ADS)

Jain, Rohit; Sebastian, K. L.

2017-06-01

We consider the problem of calculating the probability distribution function (pdf) of angular displacement for rotational diffusion in a crowded, rearranging medium. We use the diffusing diffusivity model and following our previous work on translational diffusion [R. Jain and K. L. Sebastian, J. Phys. Chem. B 120, 3988 (2016)], we show that the problem can be reduced to that of calculating the survival probability of a particle undergoing Brownian motion, in the presence of a sink. We use the approach to calculate the pdf for the rotational motion in two and three dimensions. We also propose new dimensionless, time dependent parameters, αr o t ,2 D and αr o t ,3 D, which can be used to analyze the experimental/simulation data to find the extent of deviation from the normal behavior, i.e., constant diffusivity, and obtain explicit analytical expressions for them, within our model.
The study of the wonderful: the first topographical mapping of vision in the brain.

PubMed

Fishman, Ronald S

2008-12-01

The conception by René Descartes of the human brain, notorious as it is for placing the soul or mind in the pineal gland, had yet within it the basic idea of the brain as a highly organized mechanism with topographical sensory mapping and different functions localized in specific areas. Descartes was directly led to this idea by his appreciation of what the retinal image conceived by Johannes Kepler implied, not only for the nature of vision, but for the operation of the brain in general. The linkage between Kepler and Descartes is not widely appreciated but is one of the best examples of synergism in the history of science.
Little-known aspect of Theodor Billroth's work: his contribution to musical theory.

Theodor Billroth's contribution to musical theory is discussed and evaluated. Billroth was a close friend of the composer Johannes Brahms and was himself extremely musical. At his death he left the manuscript of a book on musical theory, Wer ist-Musikalisch?, which had gone through four editions by 1912. In it he attempted to answer important questions on the nature of sound perception, the importance of rhythm as a fundamental element in music, the relation of pitch, tone, and volume, and the ways in which to account for the affective power of music. This article outlines the main concepts, contributions, and opinions offered by Billroth.
Theory of music and method of "Harmony" in J.Cepler's book "Harmony of Universe"

Smirnov, V. A.

In the Cepler's book "Harmony of Universe" edited in 1619 the theory of music as a science of that time is presented. Also the investigation of proportion corresponding to musical between orbital parameters of planets is presented. J.Cepler used comparison of musical proportion for investigation movement of celestial bodies. So that Cepler's third law was formulated as following: "Proportion between periods rotation of any two planets is one and a half of proportion average distans of this planets exactly". The Cepler's method of "Harmony" lead to explanation of existence anti-entropyc processes which are widely spreaded in nature. [Johannes Kepler. Weltharmonik. Munchen-Berlin 1939 ].
Robert Boyle, Transmutation, and the History of Chemistry before Lavoisier: A Response to Kuhn.

PubMed

Newman, William R

2014-01-01

In an influential article of 1952, Thomas Kuhn argued that Robert Boyle had little or no influence on the subsequent development of chemistry. This essay challenges Kuhn's view on two fronts. First, it shows that Johann Joachim Becher developed his hierarchical matter theory under the influence of Boyle and then transmitted it to the founder of the phlogiston theory, G. E. Stahl. Second, this essay argues that transmutational matter theories were not necessarily opposed to the existence of stable chemical species, pace Kuhn. Boyle's corpuscular theory descended largely from the tradition of "chymical atomism," which often advocated both chrysopoeia and the reality of robust chemical substances.
Simulating Statistical Power in Latent Growth Curve Modeling: A Strategy for Evaluating Age-Based Changes in Cognitive Resources

NASA Astrophysics Data System (ADS)

von Oertzen, Timo; Ghisletta, Paolo; Lindenberger, Ulman

Variability across and within individuals is a fundamental property of adult age changes in behavior [20, 21, 24]. Some people seem young for their age, others seem old; shining examples of older individuals who maintained high levels of intellectual functioning well into very old age, such as Johann Wolfgang von Goethe or Sophocles, stand in contrast to individuals whose cognitive resources are depleted by the time they reach later adulthood. A similar contrast exists between different intellectual abilities. For example, if one looks at the speed needed to identify and discriminate between different percepts, one is likely to find monotonic decline after late adolescence and early adulthood.
Instrumental images: the visual rhetoric of self-presentation in Hevelius's Machina Coelestis.

Vertesi, Janet

2010-06-01

This article places the famous images of Johannes Hevelius's instruments in his Machina Coelestis (1673) in the context of Hevelius's contested cometary observations and his debate with Hooke over telescopic sights. Seen thus, the images promote a crafted vision of Hevelius's astronomical practice and skills, constituting a careful self-presentation to his distant professional network and a claim as to which instrumental techniques guarantee accurate observations. Reviewing the reception of the images, the article explores how visual rhetoric may be invoked and challenged in the context of controversy, and suggests renewed analytical attention to the role of laboratory imagery in instrumental cultures in the history of science.

John Hyacinth de Magellan, whose Portuguese name was João Hyacintho de Magalhaens, though not a doctor nevertheless had many contacts with doctors and showed a genuine interest in disseminating medical news to his many friends and correspondents in Europe. The abundant and less formal correspondence with his friend Ribeiro Sanches forms the greater part of the work but in letters to other correspondents, including Trudaine de Montigny, Condorcet, Volta, J A Euler, Fabroni and Johann III Bernoulli, we find comments on medical subjects. The Sanches letters are particularly interesting because they are private, friend-to-friend letters that convey spontaneous and sincere thoughts and feelings.

With the death of Frederick Albert Lionel Clowes on 21 September 2016, plant sciences lost a member of that lineage of experimental morphologists which reaches back to Johann Wolfgang von Goethe. In 1949, he discovered a group of cells at the tip of the beech root apex which were metabolically inert. In 1954, he confirmed generality of this root apex feature and coined the term 'quiescent center'. He continued to study these unique cells throughout next decades up to his last papers published in 1980s. Concept of the quiescent centre of plant roots is one of the milestones in plant cell biology and plant physiology.

The 14th volume of the Acta Historica Astronomiae is the Proceedings of a Colloquium International Relationships in Astronomy (in German) organised by the History of Astronomy Section of the Astronomische Gesellschaft held on September 18 in Lilienthal, Germany. The book contains 13 articles on astronomical topics covering the 19th and 20th centuries. The first paper is by Guenther Oestmann and deals with contemporary assessments of Johann Hieronymus Schroeter's (1745-1816) astronomical works and with later judgements of the scientific importance and significance of his observations as seen by astronomers and historians. This report is complemented by a second article on Schroeter's 25-ft reflector in Lilienthal near Bremen. To this end, author Felix Luehning has constructed a scale model of the telescope, and shows how the building of a model brings a deeper understanding of function and handling of this instrument. This brings us to a third paper on telescope building in Lilienthal: Hans-Joachim Leue describes the cooperation of Johann Hieronymus Schroeter and Johann Gottlieb Schrader in developing a white reflecting metal alloy for use as telescope mirror. The fourth article, by Klaus Schillinger, describes on the basis of archival documents the aquisition history of the Herschel telescopes, including telescope quality check, repair and building. Memorial sites referring to Wilhelm Olbers, Johann Hieronymus Schroeter, Friedrich Wilhelm Bessel and Carl Friedrich Gauss are described by Arno Langkavel in two walks outlined in the very last paper of this book. Peter Brosche, in the fifth paper, discusses the rediscovery of Ceres in December1801, a discovery that was the result of the combined efforts of a theoretician (Gauss) and an observer (Zach). Juergen Hamel's paper is based on previously unused archival sources and discusses the outstanding role played by H. C. Schumacher (1780-1850, editor of the Astronomische Nachrichten) in the communication between
Composing Music with Complex Networks

NASA Astrophysics Data System (ADS)

Liu, Xiaofan; Tse, Chi K.; Small, Michael

In this paper we study the network structure in music and attempt to compose music artificially. Networks are constructed with nodes and edges corresponding to musical notes and their co-occurrences. We analyze sample compositions from Bach, Mozart, Chopin, as well as other types of music including Chinese pop music. We observe remarkably similar properties in all networks constructed from the selected compositions. Power-law exponents of degree distributions, mean degrees, clustering coefficients, mean geodesic distances, etc. are reported. With the network constructed, music can be created by using a biased random walk algorithm, which begins with a randomly chosen note and selects the subsequent notes according to a simple set of rules that compares the weights of the edges, weights of the nodes, and/or the degrees of nodes. The newly created music from complex networks will be played in the presentation.
Gender as a historical kind: a tale of two genders?

PubMed

Godman, Marion

2018-01-01

Is there anything that members of each binary category of gender have in common? Even many non-essentialists find the lack of unity within a gender worrying as it undermines the basis for a common political agenda for women. One promising proposal for achieving unity is by means of a shared historical lineage of cultural reproduction with past binary models of gender (e.g. Bach in Ethics 122:231-272, 2012). I demonstrate how such an account is likely to take on board different binary and also non-binary systems of gender. This implies that all individuals construed as members of the category, "women" are in fact not members of the same historical kind after all! I then consider different possible means of modifying the account but conclude negatively: the problem runs deeper than has been appreciated thus far.
Facial reconstruction – anatomical art or artistic anatomy?

PubMed Central

Wilkinson, Caroline

2010-01-01

Facial reconstruction is employed in the context of forensic investigation and for creating three-dimensional portraits of people from the past, from ancient Egyptian mummies and bog bodies to digital animations of J. S. Bach. This paper considers a facial reconstruction method (commonly known as the Manchester method) associated with the depiction and identification of the deceased from skeletal remains. Issues of artistic licence and scientific rigour, in relation to soft tissue reconstruction, anatomical variation and skeletal assessment, are discussed. The need for artistic interpretation is greatest where only skeletal material is available, particularly for the morphology of the ears and mouth, and with the skin for an ageing adult. The greatest accuracy is possible when information is available from preserved soft tissue, from a portrait, or from a pathological condition or healed injury. PMID:20447245
Melodic cues for metre.

PubMed

Vos, P G; van Dijk, A; Schomaker, L

1994-01-01

A method of time-series analysis and a time-beating experiment were used to test the structural and perceptual validity of notated metre. Autocorrelation applied to the flow of melodic intervals between notes from thirty fragments of compositions for solo instruments by J S Bach strongly supported the validity of bar length specifications. Time-beating data, obtained with four stimuli from the same set, played in an expressionless mode, and presented under categorically distinct tempos to different subgroups of musically trained subjects, were rather inconsistent with respect to tapped bar lengths. However, taps were most frequently given to the events in the stimuli that corresponded with the first beats according to the score notations. No significant effects of tempo on tapping patterns were observed. The findings are discussed in comparison with other examinations of metre inference from musical compositions.
Auditory Cortical Processing in Real-World Listening: The Auditory System Going Real

Bizley, Jennifer; Shamma, Shihab A.; Wang, Xiaoqin

2014-01-01

The auditory sense of humans transforms intrinsically senseless pressure waveforms into spectacularly rich perceptual phenomena: the music of Bach or the Beatles, the poetry of Li Bai or Omar Khayyam, or more prosaically the sense of the world filled with objects emitting sounds that is so important for those of us lucky enough to have hearing. Whereas the early representations of sounds in the auditory system are based on their physical structure, higher auditory centers are thought to represent sounds in terms of their perceptual attributes. In this symposium, we will illustrate the current research into this process, using four case studies. We will illustrate how the spectral and temporal properties of sounds are used to bind together, segregate, categorize, and interpret sound patterns on their way to acquire meaning, with important lessons to other sensory systems as well.

Techniques for Fault Detection and Visualization of Telemetry Dependence Relationships for Root Cause Fault Analysis in Complex Systems

NASA Astrophysics Data System (ADS)

Guy, Nathaniel

This thesis explores new ways of looking at telemetry data, from a time-correlative perspective, in order to see patterns within the data that may suggest root causes of system faults. It was thought initially that visualizing an animated Pearson Correlation Coefficient (PCC) matrix for telemetry channels would be sufficient to give new understanding; however, testing showed that the high dimensionality and inability to easily look at change over time in this approach impeded understanding. Different correlative techniques, combined with the time curve visualization proposed by Bach et al (2015), were adapted to visualize both raw telemetry and telemetry data correlations. Review revealed that these new techniques give insights into the data, and an intuitive grasp of data families, which show the effectiveness of this approach for enhancing system understanding and assisting with root cause analysis for complex aerospace systems.
Solving Biology's Iron Chemistry Problem with Ferritin Protein Nanocages.

Theil, Elizabeth C; Tosha, Takehiko; Behera, Rabindra K

cage symmetry (3-fold and 4-fold axes) and amino acid conservation coincide with function, shown by amino acid substitution effects. 3-Fold symmetry axes control Fe(2+) entry (enzyme catalysis of Fe(2+)/O2 oxidoreduction) and Fe(2+) exit (reductive ferritin mineral dissolution); 3-fold symmetry axes influence Fe(2+)exit from dissolved mineral; bacterial ferritins diverge slightly in Fe/O2 reaction mechanisms and intracage paths of iron-oxy complexes. Biosynthesis rates of ferritin protein change with Fe(2+) and O2 concentrations, dependent on DNA-binding, and heme binding protein, Bach 1. Increased cellular O2 indirectly stabilizes ferritin DNA/Bach 1 interactions. Heme, Fe-protoporphyrin IX, decreases ferritin DNA-Bach 1 binding, causing increased ferritin mRNA biosynthesis (transcription). Direct Fe(2+) binding to ferritin mRNA decreases binding of an inhibitory protein, IRP, causing increased ferritin mRNA translation (protein biosynthesis). Newly synthesized ferritin protein consumes Fe(2+) in biomineral, decreasing Fe(2)(+) and creating a regulatory feedback loop. Ferritin without iron is "apoferritin". Iron removal from ferritin, experimentally, uses biological reductants, for example, NADH + FMN, or chemical reductants, for example, thioglycolic acid, with Fe(2+) chelators; physiological mechanism(s) are murky. Clear, however, is the necessity of ferritin for terrestrial life by conferring oxidant protection (plants, animals, and bacteria), virulence (bacteria), and embryonic survival (mammals). Future studies of ferritin structure/function and Fe(2+)/O2 chemistry will lead to new ferritin uses in medicine, nutrition, and nanochemistry.

Eight years ago, a special issue in this journal published a dozen papers with new studies on the history of quantum physics. That issue was an output of a conference in Utrecht one year earlier, the second in a series organized by the then existing large-scale project coordinated by the Max Planck Institute for the History of Science and the Fritz Haber Institute. Since then, that project has produced a number of publications, workshops and other academic outcomes, but more importantly, it triggered the consolidation of an international community of historians and philosophers of science producing novel work on the history of quantum physics. Five years after the third meeting, which took place in Berlin in 2010, many of the scholars from that group and some new ones met for four days in Donostia/San Sebastian for the HQ4 meeting. The time was ripe for new results to be shared and discussed, and this issue collects some of the papers presented at that gathering.

Modern sequencing platforms produce huge amounts of data. Archiving them raises major problems but is crucial for reproducibility of results, one of the most fundamental principles of science. The widely used gzip compressor, used for reduction of storage and transfer costs, is not a perfect solution, so a few specialized FASTQ compressors were proposed recently. Unfortunately, they are often impractical because of slow processing, lack of support for some variants of FASTQ files or instability. We propose DSRC 2 that offers compression ratios comparable with the best existing solutions, while being a few times faster and more flexible. DSRC 2 is freely available at http://sun.aei.polsl.pl/dsrc. The package contains command-line compressor, C and Python libraries for easy integration with existing software and technical documentation with examples of usage. sebastian.deorowicz@polsl.pl Supplementary data are available at Bioinformatics online. © The Author 2014.

In a General Hospital in San Sebastian, 96 cases of Neisseria meningitidis infections were detected in a two years period. By the use of the disk diffusion method, we found that all causative meningococcal strains but 4 were resistant to sulfonamide (with a 300 microgram sulfadiazine disk, all isolates with a zone diameter of less than 20 mm were considered to be resistant of sulfadiazine, whereas those with zone diameters of greater than 30 mm were considered susceptible). No rifampin nor minocycline-resistant meningococci were isolated. All strains had a disk zone diameter (30 micrograms rifampin and 30 micrograms tetracycline) of greater than 20 mm. The serogroups of meningococcal strains were as follows: group A, 1; group B, 67; group C, 5 and 23 were no typed. Children less than four years of age were most frequently attacked (67,7%). The attack rate was only slightly higher in males than in females (52 and 44).

At the beginning of the Renaissance magical, witchcraft and demonological medicine still played a large role in the poor healing ability of chronic leg ulcers. This included the general administration of magical potions and topical application. An example of the manipulation of the whole body by the devil was the Abracadabra text from Johann Christoph Bitterkraut in the year 1677. The use of bewitched ointments was particularly propagated by Paracelsus in 1622; however, even as early as the beginning of the seventeenth century, the invocation of supernatural powers was slowly diminishing until at the beginning of the nineteenth century the medical schools on chronic leg ulcers could be cultivated at the universities and by specialized wound healers.
Georg Friedrich Kordenbusch and astronomy in Nuremberg in the second half of the 18th century. (German Title: Georg Friedrich Kordenbusch und die Astronomie in Nürnberg in der zweiten Hälfte des 18. Jahrhunderts)

NASA Astrophysics Data System (ADS)

Gaab, Hans

In the second half of the 18th century, Georg Friedrich Kordenbusch (1731 - 1802) was the best-known living mathematician and astronomer in Nuremberg. Being a physician by training, he obtained, in 1769, the post of lecturer in mathematics and physics at the Egidien secondary school. Subsequently, he tried in vain to re-erect the observatory, torn down in 1751. In the early 1770s, he became famous for preparing the second edition of Johann Leonhard Rost's Astronomisches Handbuch that was, in its first edition of 1718, the first compendium of astronomy written in German, and which had a wide circulation. In 1790, Kordenbusch was raised to the nobility for his achievements.

Antoine-Marie Chambeyron (1797-1851) was a disciple of Jean-Etienne Esquirol (1772-1840) that history forgot, undoubtedly because he made no original contribution to psychiatric nosography. In 1827, his interest in the medical-legal status of the insane led him to translate into French and annotate the first medical-legal psychiatric treatise ever published, which was the work of the German philosopher Johann Christoph Hoffbauer (1766-1827). His translation played a role in shaping the French Law of 1838, the first piece of modern legislation aimed at protecting the rights of mental patients and limiting the State's power to confine them arbitrarily. Chambeyron is among the least-cited contributors to the prestigious work of nineteenth-century French alienists.
From the Cover: Musical rhythm spectra from Bach to Joplin obey a 1/f power law

NASA Astrophysics Data System (ADS)

Levitin, Daniel J.; Chordia, Parag; Menon, Vinod

Much of our enjoyment of music comes from its balance of predictability and surprise. Musical pitch fluctuations follow a 1/f power law that precisely achieves this balance. Musical rhythms, especially those of Western classical music, are considered highly regular and predictable, and this predictability has been hypothesized to underlie rhythm's contribution to our enjoyment of music. Are musical rhythms indeed entirely predictable and how do they vary with genre and composer? To answer this question, we analyzed the rhythm spectra of 1,788 movements from 558 compositions of Western classical music. We found that an overwhelming majority of rhythms obeyed a 1/fβ power law across 16 subgenres and 40 composers, with β ranging from ∼0.5-1. Notably, classical composers, whose compositions are known to exhibit nearly identical 1/f pitch spectra, demonstrated distinctive 1/f rhythm spectra: Beethoven's rhythms were among the most predictable, and Mozart's among the least. Our finding of the ubiquity of 1/f rhythm spectra in compositions spanning nearly four centuries demonstrates that, as with musical pitch, musical rhythms also exhibit a balance of predictability and surprise that could contribute in a fundamental way to our aesthetic experience of music. Although music compositions are intended to be performed, the fact that the notated rhythms follow a 1/f spectrum indicates that such structure is no mere artifact of performance or perception, but rather, exists within the written composition before the music is performed. Furthermore, composers systematically manipulate (consciously or otherwise) the predictability in 1/f rhythms to give their compositions unique identities.
The effects of music on the cardiovascular system and cardiovascular health.

Music may not only improve quality of life but may also effect changes in heart rate and heart rate variability. It has been shown that cerebral flow was significantly lower when listening to 'Va pensiero' from Verdi's 'Nabucco' (70.4±3.3 cm/s) compared with 'Libiam nei lieti calici' from Verdi's 'La Traviata' (70.2±3.1 cm/s) (p<0.02) or Bach's Cantata No. 169 'Gott soll allein mein Herze haben' (70.9±2.9 cm/s) (p<0.02). There was no significant difference in cerebral flow during rest (67.6±3.3 cm/s) or when listening to Beethoven's Ninth Symphony (69.4±3.1 cm/s). It was reported that relaxing music significantly decreases the level of anxiety of patients in a preoperative setting (State-Trait Anxiety Inventory (STAI)-X-1 score 34)-to a greater extent even than orally administered midazolam (STAI-X-1 score 36) (p<0.001). In addition the score was better after surgery in the music group (STAI-X-1 score 30) compared with the midazolam group (STAI-X-1 score 34) (p<0.001). Higher effectiveness and absence of apparent adverse effects make relaxing, preoperative music a useful alternative to midazolam for premedication. In addition, there is sufficient practical evidence of stress reduction suggesting that a proposed regimen of listening to music while resting in bed after open-heart surgery is important in clinical use. After 30 min of bed rest, there was a significant difference in cortisol levels between the music (484.4 mmol/l) and the non-music group (618.8 mmol/l) (p<0.02). Vocal and orchestral music produce significantly better correlations between cardiovascular or respiratory signals compared with music with a more uniform emphasis (p<0.05). The greatest benefit on health is visible with classical music and meditation music, whereas heavy metal music or techno are not only ineffective but possibly dangerous and can lead to stress and/or life-threatening arrhythmias. The music of many composers most effectively improves quality of life, will increase health

Experimental evidence demonstrates robust cross-modal matches between music and colors that are mediated by emotional associations. US and Mexican participants chose colors that were most/least consistent with 18 selections of classical orchestral music by Bach, Mozart, and Brahms. In both cultures, faster music in the major mode produced color choices that were more saturated, lighter, and yellower whereas slower, minor music produced the opposite pattern (choices that were desaturated, darker, and bluer). There were strong correlations (0.89 < r < 0.99) between the emotional associations of the music and those of the colors chosen to go with the music, supporting an emotional mediation hypothesis in both cultures. Additional experiments showed similarly robust cross-modal matches from emotionally expressive faces to colors and from music to emotionally expressive faces. These results provide further support that music-to-color associations are mediated by common emotional associations.
Intra- and inter-population polymorphism in Coletinia maggii (Grassi, 1887) (Zygentoma: Nicoletiidae), an inhabitant of soil, mesovoid shallow substratum (MSS) and caves--A challenge for the strict classification of subterranean fauna?

New locations of Coletinia maggii (Grassi, 1887) have been discovered in the center of the Iberian Peninsula in different types of subterranean environments, such as a stony layer in the subsoil of an alluvial plain, an alluvial Mesovoid Shallow Substratum or Milieu Souterrain Superficiel (MSS) and a gypsum cave. This is the first record of both an alluvial MSS in the center of the Iberian Peninsula and of a subterranean species living in it. The high number of specimens captured allowed the first detailed study of the morphological intra- and inter-population variations of this species. The implications of its presence in these different environments, its wide distribution area across Europe, and the relevance of the morphological variation in the characters for the taxonomy of this species are discussed. Based on the results, Coletinia hernandoi Molero, Bach & Gaju, 2013 is proposed as a new synonym of C. maggii.

Your own actions influence how you perceive other people: A misattribution of action appraisals

PubMed Central

Tipper, Steven P.; Bach, Patric

2008-01-01

The attribution of personal traits to other persons depends on the actions the observer performs at the same time (Bach & Tipper, 2007). Here, we show that the effect reflects a misattribution of appraisals of the observers’ own actions to the actions of others. We exploited spatial compatibility effects to manipulate how fluently—how fast and how accurately—participants identified two individuals performing sporty or academic actions. The traits attributed to each person in a subsequent rating task depended on the fluency of participants’ responses in a specific manner. An individual more fluently identified while performing the academic action appeared more academic and less sporty. An individual more fluently identified while performing the sporty action appeared sportier. Thus, social perception is—at least partially—embodied. The ease of our own responses can be misattributed to the actions of others, affecting which personal traits are attributed to them. PMID:21633518

In this study, bovine lactoferrin (bLf), an iron-binding glycoprotein considered an important nutraceutical protein because of its several properties, was expressed in Pichia pastoris KM71-H under AOX1 promoter control, using pJ902 as the recombinant plasmid. Dot blotting analysis revealed the expression of recombinant bovine lactoferrin (rbLf) in Pichia pastoris. After Bach fermentation and purification by molecular exclusion, we obtained an expression yield of 3.5 g/L of rbLf. rbLf and predominantly pepsin-digested rbLf (rbLfcin) demonstrated antibacterial activity against Escherichia coli (E. coli) BL21DE3, Staphylococcus aureus (S. aureus) FRI137, and, in a smaller percentage, Pseudomonas aeruginosa (Ps. Aeruginosa) ATCC 27833. The successful expression and characterization of functional rbLf expressed in Pichia pastoris opens a prospect for the development of natural antimicrobial agents produced recombinantly.

This paper investigated whether music has reinforcing and discriminative stimulus properties in goldfish. Experiment 1 examined the discriminative stimulus properties of music. The subjects were successfully trained to discriminate between two pieces of music--Toccata and Fugue in D minor (BWV 565) by J. S. Bach and The Rite of Spring by I. Stravinsky. Experiment 2 examined the reinforcing properties of sounds, including BWV 565 and The Rite of Spring. We developed an apparatus for measuring spontaneous sound preference in goldfish. Music or noise stimuli were presented depending on the subject's position in the aquarium, and the time spent in each area was measured. The results indicated that the goldfish did not show consistent preferences for music, although they showed significant avoidance of noise stimuli. These results suggest that music has discriminative but not reinforcing stimulus properties in goldfish. Copyright © 2013 Elsevier B.V. All rights reserved.

In September - November 2007 the first high resolution marine seismic campaign on the North-Central coast of Venezuela was carried out between Cabo Codera and Golfo Triste. The principal aim of this work was to characterize the active San Sebastian Fault (SSF) and to analyze Cenozoic sedimentation on the Venezuela shelf focusing on: i) effects of active tectonics and ii) coastal landslides/flashflood deposits related to 1999 Vargas catastrophic event or to similar phenomena. Data were acquired onboard R/V GUAIQUERI II from the Oceanographic Institute of the Oriente University. The seismic source was a "CENTIPEDE" sparker (RCGM) operated between 300 and 600 J, 1.3 kHz main frequency. We used a single-channel streamer with 10 hydrophones. In total, 49 seismic profiles were collected, with a cumulative length of 1000 km approximately. In these seismic profiles we identified and separated the deposits into three main units. Unit (U1) comprises low energy reflectors mainly dipping in southward direction (i.e. toward the coast bounded by the San Sebastian Fault). This unit also includes a number of isolated acoustic anomalies, which we tentatively interpret as coral reefs. Its top is defined as Basal Erosional Discontinuity (BED) onto which Unit 2 (U2) deposits are onlapping. U2 is acoustically well-stratified, with strong reflectors. Gradual variations in thickness and a wavy configuration allow us to interpret U2 as probably Quaternary current-related deposits. Last Unit (U3) was defined on the Venezuela shelf and corresponds to prograding sequences probably related to the terrigenous input of the Tuy River. Impact of eustatic fluctuations on these deposits are discussed. The data were also used to construct a simplified bathymetry of the studied area. The lateral transition from the western Cariaco-Tuy pull-apart basin to the (single) SSF was clearly imaged (mostly folds and gravity faults). The survey also displayed prograding sediments bodies in La Tortuga Shelf
Compensated electron and hole pockets in an underdoped high- Tc superconductor

We report quantum oscillations in the underdoped high-temperature superconductor YBa2Cu3O6+x over a wide range in magnetic field 28≤μ0H≤85T corresponding to ≈12 oscillations, enabling the Fermi surface topology to be mapped to high resolution. As earlier reported by Sebastian [Nature (London) 454, 200 (2008)10.1038/nature07095], we find a Fermi surface comprising multiple pockets, as revealed by the additional distinct quantum oscillation frequencies and harmonics reported in this work. We find the originally reported broad low-frequency Fourier peak at ≈535T to be clearly resolved into three separate peaks at ≈460 , ≈532 , and ≈602T , in reasonable agreement with the reported frequencies of Audouard [Phys. Rev. Lett. 103, 157003 (2009)10.1103/PhysRevLett.103.157003]. However, our increased resolution and angle-resolved measurements identify these frequencies to originate from two similarly sized pockets with greatly contrasting degrees of interlayer corrugation. The spectrally dominant frequency originates from a pocket (denoted α ) that is almost ideally two-dimensional in form (exhibiting negligible interlayer corrugation). In contrast, the newly resolved weaker adjacent spectral features originate from a deeply corrugated pocket (denoted γ ). On comparison with band structure, the d -wave symmetry of the interlayer dispersion locates the minimally corrugated α pocket at the “nodal” point knodal=(π/2,π/2) , and the significantly corrugated γ pocket at the “antinodal” point kantinodal=(π,0) within the Brillouin zone. The differently corrugated pockets at different locations indicate creation by translational symmetry breaking—a spin-density wave has been suggested from the suppression of Zeeman splitting for the spectrally dominant pocket. In a broken-translational symmetry scenario, symmetry points to the nodal (α) pocket corresponding to holes, with the weaker antinodal (γ) pocket corresponding to electrons—likely responsible

Mark Lancaster French Crossings: III. The Smile of the Tiger PubMed Central Jones, Colin 2016-01-01 This article continues the theme of ‘French Crossings’ explored in other Presidential Addresses by focussing on the border zone between the human and the animal. The focus is on the allegedly tiger-like character attributed to Maimilien Robespierre, particularly after his fall from power and his execution in 1794. This theme is explored in terms of Thermidorian propaganda, French Revolutionary historiography and the ancient discipline of physiognomy, which was reactivated by Johann-Caspar Lavater in the late eighteenth century and still influential through much of the nineteenth. Robespierre’s animal rather than human status was also held to emerge in his inability to smile or laugh, a significant point also in that the meaning of the smile was changing in the same period.

In it the authors argue that there is no reason why "gold standard" acute hospital care cannot be cost-effectively delivered from small, well-equipped local hospitals in the future, but that achieving this will require "a number of (current) NHS conventions to be defied". Metaphysics for an enlightened public: The controversy over monads in Germany, 1746-1748. PubMed Broman, Thomas 2012-03-01 This essay analyzes the controversy that attended the prize essay question on monads proposed by the Berlin Academy of Sciences in 1746. The controversy was first touched off by an anonymous pamphlet published by the mathematician Leonhard Euler, the academy's most well known member, that attacked the doctrine of monads. It peaked with the awarding of the prize to Johann Heinrich Gottlob Justi, whose winning essay closely followed Euler's arguments. This essay discusses the controversy as one instance in a broader quarrel in the German academic community over the suitability of Christian Wolff's philosophy as the foundation for a broad range of academic disciplines, including natural philosophy. It also analyzes the controversy as displaying the central role of the periodical press in the emergent German public sphere. [Stapler and manual bronchial anastomosis--results of a consecutive trial series]. PubMed Junginger, T; Walgenbach, S; Pichlmaier, H 1989-01-01 After lobectomy and pneumonectomy in experimental evaluations stapled bronchial closures showed the lowest incidence of inflammatory reaction and the highest strength determined by leakage pressure compared with other suture material. A total of 233 lung resections-performed at Surgical University Clinic Köln-Lindenthal and the Clinic for General and Abdominal Surgery of the Johannes-Gutenberg-Universität Mainz--were reviewed. Mechanical stapling reduced the rate of bronchopleural fistulas to 2.0% compared with 7.1% after manual suturing. In parallel, mortality related to bronchial stump leakage decreased to 0.7%. Main advantages of bronchial closure with staplers are the simplicity of their use, the speed and the uniformity of the closure. Thereby stapling devices are valuable completions in pulmonary surgery. Heike Kamerlingh Onnes: Master of Experimental Technique and Quantitative Research NASA Astrophysics Data System (ADS) Reif-Acherman, Simón Heike Kamerlingh Onnes (1853-1926), born a century and a half ago, was a major protagonist in the so-called Second Golden Age of Dutch Science. He devoted his career to the emerging field of low-temperature physics. His particular concern was to test the theories of his older compatriot Johannes Diderik van der Waals (1837-1923) by creating a style of research that was characterized by meticulous planning, precise measurement, and constant improvement of techniques and instruments. He made numerous contributions to low-temperature physics, but I focus on his liquefaction of helium, for which he received the Nobel Prize in Physics for 1913, and on his discovery of superconductivity. He became known internationally as le gentleman du zéro absolu. The Surprising History of Claims for Life on the Sun NASA Astrophysics Data System (ADS) Crowe, Michael J. 2011-11-01 Because astronomers are now convinced that it is impossible for life, especially intelligent life, to exist on the Sun and stars, it might be assumed that astronomers have always held this view. This paper shows that throughout most of the history of astronomy, some intellectuals, including a number of well-known astronomers, have advocated the existence of intelligent life on our Sun and thereby on stars. Among the more prominent figures discussed are Nicolas of Cusa, Giordano Bruno, William Whiston, Johann Bode, Roger Boscovich, William Herschel, Auguste Comte, Carl Gauss, Thomas Dick, John Herschel, and François Arago. One point in preparing this paper is to show differences between the astronomy of the past and that of the present.

The role of tone sensation and musical stimuli in early experimental psychology. PubMed Klempe, Sven Hroar 2011-01-01 In this article, the role of music in early experimental psychology is examined. Initially, the research of Wilhelm Wundt is considered, as tone sensation and musical elements appear as dominant factors in much of his work. It is hypothesized that this approach was motivated by an understanding of psychology that dates back to Christian Wolff 's focus on sensation in his empirical psychology of 1732. Wolff, however, had built his systematization of psychology on Gottfried Wilhelm von Leibniz, who combined perception with mathematics,and referred to music as the area in which sensation is united with numerical exactitude. Immanuel Kant refused to accept empirical psychology as a science, whereas Johann Friedrich Herbart reintroduced the scientific basis of empirical psychology by, among other things, referring to music. Ephemerides and information: Investigations on the content of Berlin calendars up to Bode's Astronomisches Jahrbuch. (German Title: Ephemeriden und Informationen: Inhaltliche Untersuchungen Berliner Kalender bis zu Bodes Astronomischem Jahrbuch) NASA Astrophysics Data System (ADS) Hamel, Jürgen This contributions investigates a line of tradition which started already with the oldest calenders, i.e. to add an `educating' appendix. As a wide-spread medium, calendars were suitable for the dissemination of astrological views, the explanation of astronomical facts, of important activities for the home and the stable, for health protection, agriculture, and social connections. The calendars of the Berlin Academy, authored by Gottfried Kirch and his successors, fit well into this picture: also astrology played an important role. Kirch had added to his ephemerides of 1681 to 1692 own and other observations and contributions. This lead to a form, which superseded `normal' calenders, a form in which also Johann Elert Bode's Berliner Astronomisches Jahrbuch appeared from 1776 to 1829.
