Bacteriophages as a model for studying carbon regulation in aquatic system

The interconversion of carbon in organic, inorganic and refractory carbon is still beyond the grasp of present environmentalists. The bacteria and their phages, being the most abundant constituents of the aquatic environment, represent an ideal model for studing carbon regulation in the aquatic system. The refractory dissolved organic carbon (DOC), a recently coined terminology from the microbe-driven conversion of bioavailable organic carbon into difficult-to-digest refractory DOC by microbial carbon pump (MCP), is suggested to have the potential to revolutionize our view of carbon sequestration. It is estimated that about 95% of organic carbon is in the form of refractory DOC, which is the largest pool of organic matter in the ocean. The refractory DOC is supposed to be the major factor in the global carbon cycle whose source is not yet well understood. A key element of the carbon cycle is the microbial conversion of dissolved organic carbon into inedible forms. The time studies of phage-host interaction under control conditions reveal their impact on the total carbon content of the source and their interconversion among organic, inorganic and other forms of carbon with respect to control source. The TOC- analysis statistics stipulate an increase in inorganic carbon content by 15-25 percent in the sample with phage as compared to the sample without phage. The results signify a 60-70 fold increase in inorganic carbon content in sample with phage, whereas, 50-55 fold in the case of sample without phages as compared with control. This increase in inorganic carbon content may be due to lysis of the host cell releasing its cellular constituents and utilization of carbon constituent for phage assembly and development. It also proves the role of phages in regulating the carbon flow in aquatic systems like oceans, where their concentration outnumbered other species

Solidification and stabilization of chromium laden wastes in cementitious binders

Solidification/stabilization (S/S) technology was applied to a simulated sludge containing chromium. Leaching tests such as toxicity characteristic leaching procedure (TCLP), ANS 16.1 and multiple TCLP tests conducted on stabilized blocks showed that chromium was immobilized by the binder studied. A linear relationship was obtained between the cumulative fraction of chromium leached and time1/2 in the stabilized samples proving that chromium is leached by diffusion. The leachability indices obtained for the solidified materials satisfy the guidance value as per US Nuclear Regulatory Commission. Chromium concentrations in the TCLP leachates were well within the regulatory levels of the United States Environmental Protection Agency. Microchemistry and morphology of the stabilized samples were studied using Fourier transformation infrared (FTIR) technique and scanning electron microscopy (SEM). FTIR confirms the presence of ν2 CO3 band and O–H stretching of Ca(OH)2 and SEM shows uniform dense crystalline morphologies in all the samples. X-ray diffraction indicates the presence of bentorite, which proves that Cr replaces Al in the ettringit

Severe early onset preeclampsia: short and long term clinical, psychosocial and biochemical aspects

Preeclampsia is a pregnancy specific disorder commonly defined as de novo hypertension and proteinuria after 20 weeks gestational age. It occurs in approximately 3-5% of pregnancies and it is still a major cause of both foetal and maternal morbidity and mortality worldwide1. As extensive research has not yet elucidated the aetiology of preeclampsia, there are no rational preventive or therapeutic interventions available. The only rational treatment is delivery, which benefits the mother but is not in the interest of the foetus, if remote from term. Early onset preeclampsia (<32 weeks’ gestational age) occurs in less than 1% of pregnancies. It is, however often associated with maternal morbidity as the risk of progression to severe maternal disease is inversely related with gestational age at onset2. Resulting prematurity is therefore the main cause of neonatal mortality and morbidity in patients with severe preeclampsia3. Although the discussion is ongoing, perinatal survival is suggested to be increased in patients with preterm preeclampsia by expectant, non-interventional management. This temporising treatment option to lengthen pregnancy includes the use of antihypertensive medication to control hypertension, magnesium sulphate to prevent eclampsia and corticosteroids to enhance foetal lung maturity4. With optimal maternal haemodynamic status and reassuring foetal condition this results on average in an extension of 2 weeks. Prolongation of these pregnancies is a great challenge for clinicians to balance between potential maternal risks on one the eve hand and possible foetal benefits on the other. Clinical controversies regarding prolongation of preterm preeclamptic pregnancies still exist – also taking into account that preeclampsia is the leading cause of maternal mortality in the Netherlands5 - a debate which is even more pronounced in very preterm pregnancies with questionable foetal viability6-9. Do maternal risks of prolongation of these very early pregnancies outweigh the chances of neonatal survival? Counselling of women with very early onset preeclampsia not only comprises of knowledge of the outcome of those particular pregnancies, but also knowledge of outcomes of future pregnancies of these women is of major clinical importance. This thesis opens with a review of the literature on identifiable risk factors of preeclampsia

Dissociation Protocols Used for Sarcoma Tissues Bias the Transcriptome Observed in Single-Cell and Single-Nucleus RNA Sequencing

BACKGROUND: Single-cell RNA-seq has emerged as an innovative technology used to study complex tissues and characterize cell types, states, and lineages at a single-cell level. Classification of bulk tumors by their individual cellular constituents has also created new opportunities to generate single-cell atlases for many organs, cancers, and developmental models. Despite the tremendous promise of this technology, recent evidence studying epithelial tissues and diverse carcinomas suggests the methods used for tissue processing, cell disaggregation, and preservation can significantly bias gene expression and alter the observed cell types. To determine whether sarcomas - tumors of mesenchymal origin - are subject to the same technical artifacts, we profiled patient-derived tumor explants (PDXs) propagated from three aggressive subtypes: osteosarcoma (OS), Ewing sarcoma (ES), desmoplastic small round cell tumor (DSRCT). Given the rarity of these sarcoma subtypes, we explored whether single-nuclei RNA-seq from more widely available archival frozen specimens could accurately be identified by gene expression signatures linked to tissue phenotype or pathognomonic fusion proteins. RESULTS: We systematically assessed dissociation methods across different sarcoma subtypes. We compared gene expression from single-cell and single-nucleus RNA-sequencing of 125,831 whole-cells and nuclei from ES, DSRCT, and OS PDXs. We detected warm dissociation artifacts in single-cell samples and gene length bias in single-nucleus samples. Classic sarcoma gene signatures were observed regardless of the dissociation method. In addition, we showed that dissociation method biases could be computationally corrected. CONCLUSIONS: We highlighted transcriptional biases, including warm dissociation and gene-length biases, introduced by the dissociation method for various sarcoma subtypes. This work is the first to characterize how the dissociation methods used for sc/snRNA-seq may affect the interpretation of the molecular features in sarcoma PDXs

Cohort for Tuberculosis Research by the Indo-US Medical Partnership (CTRIUMPH): protocol for a multicentric prospective observational study

INTRODUCTION: Tuberculosis disease (TB) remains an important global health threat. An evidence-based response, tailored to local disease epidemiology in high-burden countries, is key to controlling the global TB epidemic. Reliable surrogate biomarkers that predict key active disease and latent TB infection outcomes are vital to advancing clinical research necessary to ‘End TB’. Well executed longitudinal studies strengthening local research capacity for addressing TB research priorities and advancing biomarker discovery are urgently needed. METHODS AND ANALYSIS: The Cohort for Tuberculosis Research by the Indo-US Medical Partnership (CTRIUMPH) study conducted in Byramjee Jeejeebhoy Government Medical College (BJGMC), Pune and National Institute for Research in Tuberculosis (NIRT), Chennai, India, will establish and maintain three prospective cohorts: (1) an Active TB Cohort comprising 800 adults with pulmonary TB, 200 adults with extrapulmonary TB and 200 children with TB; (2) a Household Contact Cohort of 3200 adults and children at risk of developing active disease; and (3) a Control Cohort consisting of 300 adults and 200 children with no known exposure to TB. Relevant clinical, sociodemographic and psychosocial data will be collected and a strategic specimen repository established at multiple time points over 24 months of follow-up to measure host and microbial factors associated with (1) TB treatment outcomes; (2) progression from infection to active TB disease; and (3) Mycobacterium tuberculosis transmission among Indian adults and children. We anticipate CTRIUMPH to serve as a research platform necessary to characterise some relevant aspects of the TB epidemic in India, generate evidence to inform local and global TB control strategies and support novel TB biomarker discovery. ETHICS AND DISSEMINATION: This study is approved by the Institutional Review Boards of NIRT, BJGMC and Johns Hopkins University, USA. Study results will be disseminated through peer-reviewed journals and research conferences. FUNDING: NIH/DBT Indo-US Vaccine Action Programme and the Indian Council of Medical Research

Measurements of jet multiplicity and differential production cross sections of Z+jets events in proton-proton collisions at sqrt(s)=7TeV

Measurements of differential cross sections are presented for the production of a Z boson and at least one hadronic jet in proton-proton collisions at root s = 7 TeV, recorded by the CMS detector, using a data sample corresponding to an integrated luminosity of 4.9 fb(-1). The jet multiplicity distribution is measured for up to six jets. The differential cross sections are measured as a function of jet transverse momentum and pseudorapidity for the four highest transverse momentum jets. The distribution of the scalar sum of jet transverse momenta is also measured as a function of the jet multiplicity. The measurements are compared with theoretical predictions at leading and next-to-leading order in perturbative QCD.Austrian Federal Ministry of Science, Research and EconomyAustrian Science FundBelgian Fonds de la Recherche ScientifiqueFonds voor Wetenschappelijk OnderzoekConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Fundação de Amparo à Pesquisa do Estado do Rio de Janeiro (FAPERJ)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Bulgarian Ministry of Education and ScienceCERNChinese Academy of SciencesMinistry of Science and TechnologyNational Natural ScienceFoundationofChinaColombian FundingAgency (COLCIENCIAS)Croatian Ministry of Science, Education, and SportCroatian Science FoundationResearch Promotion Foundation, CyprusMinistry of Education and Research, EstoniaEstonian Research Council, EstoniaEuropean Regional Development Fund, EstoniaAcademy of FinlandFinnish Ministry of Education and CultureHelsinki Institute of PhysicsInstitut National de Physique Nucleaire et de Physique des Particules / CNRS, FranceCommissariat a l&apos;Energie Atomique et aux Energies Alternatives / CEA, FranceBundesministerium fur Bildung und Forschung, GermanyDeutsche Forschungsgemeinschaft, GermanyHelmholtz-Gemeinschaft Deutscher Forschungs zentren, GermanyGeneral Secretariat for Research and Technology, GreeceNational Scientific Research Foundation, HungaryNational Innovation Office, HungaryDepartment of Atomic Energy, IndiaDepartment of Science and Technology, IndiaInstitute for Studies in Theoretical Physics and Mathematics, IranScience Foundation, IrelandIstituto Nazionale di Fisica Nucleare, ItalyKorean Ministry of Education, Science and Technology, Republic of KoreaWorld Class University program of NRF, Republic of KoreaLithuanian Academy of SciencesMinistry of Education, and University of Malaya (Malaysia)Mexican Funding Agency (CINVESTAV)Mexican Funding Agency (CONACYT)Mexican Funding Agency (SEP)Mexican Funding Agency (UASLP-FAI)Ministry of Business, Innovation and Employment, New ZealandPakistan Atomic Energy CommissionMinistry of Science and Higher Education, PolandNational Science Centre, PolandFundacao para a Cienciaea Tecnologia, PortugalJINR, DubnaMinistry of Education and Science of the Russian FederationFederal Agency of Atomic Energy of the Russian FederationRussian Academy of SciencesRussian Foundation for Basic ResearchMinistry of Education, Science and Technological Development of SerbiaSecretaria de Estado de Investigacion, Desarrollo e Innovacion and Programa Consolider-Ingenio, SpainSwiss Funding Agency (ETH Board)Swiss Funding Agency (ETH Zurich)Swiss Funding Agency (PSI)Swiss Funding Agency (SNF)Swiss Funding Agency (UniZH)Swiss Funding Agency (Canton Zurich)Swiss Funding Agency (SER)Ministry of Science and Technology, TaipeiThailand Center of Excellence in PhysicsInstitute for the Promotion of Teaching Science andTechnologyofThailandSpecialTaskForceforActivating ResearchNational Science and Technology Development Agency of ThailandScientific and Technical Research Council of TurkeyTurkish Atomic Energy AuthorityNational Academy of Sciences of Ukraine, UkraineState Fund for Fundamental Researches, UkraineScience and Technology Facilities Council, United KingdomU.S. Department of EnergyU.S. National Science FoundationMarie Curie programEuropean Research CouncilEPLANET (European Union)Leventis FoundationA.

Measurement of the triple-differential cross section for photon + jets production in proton-proton collisions at sqrt (s) = 7 TeV

A measurement of the triple-differential cross section, , in photon + jets final states using a data sample from proton-proton collisions at = 7 TeV is presented. This sample corresponds to an integrated luminosity of 2.14 fb(-1) collected by the CMS detector at the LHC. Photons and jets are reconstructed within a pseudorapidity range of |eta| 30 GeV, respectively. The measurements are compared to theoretical predictions from the sherpa leading-order QCD Monte Carlo event generator and the next-to-leading-order perturbative QCD calculation from jetphox. The predictions are found to be consistent with the data over most of the examined kinematic region.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP
