    As this paper aims to highlight, the Assyrian Empire’s language environment, and in particular its scribal production, was diglossic, with a sharp distinction between the highly codified literary language of Standard Babylonian for high status texts and three vernacular languages for lower status communications (Neo-Assyrian, Neo-Babylonian and Aramaic). It is argued that between these languages, the distinction between the highly codified lect on the one hand and the three vernacular languages on the other hand is far more significant than the fact that three of these languages were written in cuneiform and the other in alphabetic script

    A First Search for coincident Gravitational Waves and High Energy Neutrinos using LIGO, Virgo and ANTARES data from 2007

    We present the results of the first search for gravitational wave bursts associated with high energy neutrinos. Together, these messengers could reveal new, hidden sources that are not observed by conventional photon astronomy, particularly at high energy. Our search uses neutrinos detected by the underwater neutrino telescope ANTARES in its 5 line configuration during the period January - September 2007, which coincided with the fifth and first science runs of LIGO and Virgo, respectively. The LIGO-Virgo data were analysed for candidate gravitational-wave signals coincident in time and direction with the neutrino events. No significant coincident events were observed. We place limits on the density of joint high energy neutrino - gravitational wave emission events in the local universe, and compare them with densities of merger and core-collapse events.Comment: 19 pages, 8 figures, science summary page at http://www.ligo.org/science/Publication-S5LV_ANTARES/index.php.

    Activation of MEK1 or MEK2 isoform is sufficient to fully transform intestinal epithelial cells and induce the formation of metastatic tumors

    <p>Abstract</p> <p>Background</p> <p>The Ras-dependent ERK1/2 MAP kinase signaling pathway plays a central role in cell proliferation control and is frequently activated in human colorectal cancer. Small-molecule inhibitors of MEK1/MEK2 are therefore viewed as attractive drug candidates for the targeted therapy of this malignancy. However, the exact contribution of MEK1 and MEK2 to the pathogenesis of colorectal cancer remains to be established.</p> <p>Methods</p> <p>Wild type and constitutively active forms of MEK1 and MEK2 were ectopically expressed by retroviral gene transfer in the normal intestinal epithelial cell line IEC-6. We studied the impact of MEK1 and MEK2 activation on cellular morphology, cell proliferation, survival, migration, invasiveness, and tumorigenesis in mice. RNA interference was used to test the requirement for MEK1 and MEK2 function in maintaining the proliferation of human colorectal cancer cells.</p> <p>Results</p> <p>We found that expression of activated MEK1 or MEK2 is sufficient to morphologically transform intestinal epithelial cells, dysregulate cell proliferation and induce the formation of high-grade adenocarcinomas after orthotopic transplantation in mice. A large proportion of these intestinal tumors metastasize to the liver and lung. Mechanistically, activation of MEK1 or MEK2 up-regulates the expression of matrix metalloproteinases, promotes invasiveness and protects cells from undergoing anoikis. Importantly, we show that silencing of MEK2 expression completely suppresses the proliferation of human colon carcinoma cell lines, whereas inactivation of MEK1 has a much weaker effect.</p> <p>Conclusion</p> <p>MEK1 and MEK2 isoforms have similar transforming properties and are able to induce the formation of metastatic intestinal tumors in mice. Our results suggest that MEK2 plays a more important role than MEK1 in sustaining the proliferation of human colorectal cancer cells.</p

    Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

    Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

    The rhetorics of finding a new identity in a multi-religious and multi-ethnic society : the case of the book of Chronicles

    Get PDF
    The original publication is available at http://www.ve.org.zaPublication of this article was funded by the Stellenbosch University Open Access Fund.Scholars generally agree that the Books of Chronicles are the products of certain Israelite (Levitical) groups in the Persian province of Jehud who struggled with the dissonance between their older historical and theological traditions on the one hand, and their present reality on the other hand. Within the totally different conditions under Persian rule (a multi-religious and multi-ethnic society) they had to find a new identity. The primary focus of this article is to examine the rhetorics of the intense struggle for a new identity presented to the reader in the Books of Chronicles. It is argued that this new identity represented a shift from a historically-defined identity that lasted from the monarchical period to the early postexilic phase, to a cultic identity during the Persian era. The article also endeavours to relate the identity forming discourse of these biblical books to the present processes in post-apartheid South African society. The question is asked whether a similar shift can be observed in this modern situation.Publisher's versio

    Anything new under the sun? : exploring further avenues for writing another commentary on Chronicles

Acta Theologica, 38(26):325-348, doi:10.18820/23099089/actat.sup26.19.The original publication is available at http://www.scielo.org.zaOver the past two decades, there has been an explosion of new commentaries on Chronicles. Scholars may justifiably ask whether there is anything new under the sun to investigate in another commentary on this book. Having been contracted to produce a commentary for the Old Testament Library series (as follow-up to Japhet's majestic commentary), I am investigating some new avenues for this endeavour. Three potential areas are discussed: utilizing Achaemenid royal inscriptions and written records for the interpretation of Chronicles; revisiting theories on the composition of Chronicles, and bringing Chronicles and Pentateuchal studies into conversation with one another.http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S1015-87582018000200021&lng=pt&nrm=isoPublisher's versio

    Human dignity and the construction of identity in the Old Testament

    CITATION: Jonker, L. 2010. Human dignity and the construction of identity in the Old Testament. Scriptura, 105:594-607, doi:10.7833/105-0-160.The original publication is available at http://scriptura.journals.ac.zaThe status of Israel changed dramatically as a result of the Babylonian exile and its aftermath during the Persian era. Whereas the self-understanding of the people was closely linked to the Davidic monarchy during the pre-exilic time, the post-exilic community had to face the reality of their provincial existence under Persian imperial rule. The sociopolitical and socio-cultural environment changed dramatically because of these events, resulting in renewed processes of identity negotiation in Israel. We witness different attempts at verbalizing these processes in the biblical writings. The impact of the Persian imperial context on the self-understanding of the community in Jerusalem will be investigated with special reference to the Books of Chronicles. In these books – different to from e.g. Ezra-Nehemiah – a tendency towards inclusivism can be detected in the process of identity negotiation. This paper will show how this tendency relates to the qualified tolerance that was characteristic of the Persian (Achaemenid) era.http://scriptura.journals.ac.za/pub/article/view/160Publisher's versio

    CITATION: Jonker, L. C. 2017. Satan made me do it! : the development of a Satan figure as social-theological diagnostic strategy from the late Persian imperial era to early Christianity. Old Testament Essays, 30(2):348-366, doi:10.17159/2312-3621/2017/v30n2a10.The original publication is available at http://www.scielo.org.zaThe purpose of this article is, first of all, to provide a short overview of the socio-religious development to personalise evil into a Satan figure alongside God. Thereafter, I will provide one biblical example which stands at the beginning of this development, namely 1 Chr 21. This text analysis will merely serve as one example to illustrate the relationship between the socio-religious developments in the Second Temple period and biblical textual formation through the reinterpretation of earlier traditions. In a last section, I will reflect on how our awareness of this relationship between socio-religious development and reinterpretation affects how Christian theology participates in social-theological diagnostics today.http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S1010-99192017000200010Publisher's versio

    Text in a multidimensional exegetical approach

    CITATION: Jonker, L. C. 1993. Text in a multidimensional exegetical approach. Scriptura, 46:100-115, doi:10.7833/46-0-1641.The original publication is available at http://scriptura.journals.ac.zaThe quest towards a multidimensional exegetical approach arises from the present state of the exegetical discipline. Presently, this discipline is characterized by an overwhelming variety of methodology, but also by exclusivistic claims made by exegetes. In developing a multidimensional approach, various theoretical issues should be taken into account. One of these important issues is the development which took place in literary and biblical studies with regard to the concepts ‘text’ and meaning. A short overview of this development is provided. Thereafter, a proposal towards a multidimensional exegetical approach, namely that of Daniel Patte, is described and evaluated. The article ends with the formulation of guidelines for research towards a multidimensional exegetical approach, and with a short discussion of the author’s own proposal.Publisher's versio
