description: Objective: To describe retention in HIV care based on various definitions of retention in the modern treatment era. Design: A cohort study of people enrolled in care at seven mostly urban HIV clinics across the United States, 2010 - 2018. Methods: We estimated retention based on missed visits, kept visits, kept encounters (clinical visits, CD4þ cell counts, and viral loads), and HIV labs. We contrasted risk factors for retention by different definitions and estimated odds ratios for viral suppression and hazard ratios for mortality in 2 years immediately following the year in which retention was defined (the study year). Results: Across 108 171 person-years (N ¼ 21 481 people), in 71% of years, people kept ≥75% of scheduled visits; in 78%, people kept ≥2 visits >90 days apart; in 74%, people had ≥2 HIV labs >90 days apart; and in 47%, people had no gaps >6 months in clinic visits. Missing >25% of scheduled visits despite attending ≥2 visits >90 days apart was associated with nonwhite non-Hispanic race/ethnicity, history of injection drug use, and prior AIDS diagnosis. In contrast, attending ≥75% of scheduled visits while not attending ≥2 visits >90 days apart was associated with male sex, white race, no injection drug use history, and no prior AIDS diagnosis. Subsequent viral nonsuppression was more strongly associated with missed- than kept-visit measures of retention; 2-year mortality was only associated with failure to be retained by missed-visit measures. Discussion: Missed and kept-visit definitions of retention capture different constructs. Missed-visit measures are more strongly associated with poor HIV outcomes.

description: In the present paper we propose a mechanism of the structural instability with a periodic charge ordering in two-dimensional isotropic conductors with a closed Fermi surface which completely excludes the conventional nesting mechanism. We show that the structural instability in such conductors may arise as a topological reconstruction under which the initially closed Fermi surface is transformed into an open one. We have found that the order parameter of the charge ordering ground state may exceed one hundredth of the Fermi energy. Furthermore, this charge ordering is a quantum phase transition with respect to the dimensionless coupling constant $λ$ related to the mechanism that drives the band reconstruction (e. g. electron-phonon coupling), with the critical value given by $λ_c= (1+2/π)^{-1}$. Preliminary estimations show that the suggested mechanism can be the origin of density waves observed in such materials as high$-T_c$ cuprates or graphite intercalates.

description: The U.S. Air Force (USAF) proposed a land-swap, as part of the 2012 National Defense Authorization Act, Section 2851, Land Conveyance program a 220-acre parcel of land, for the property designated as Richardson Training Area (RTA) 419, located on Joint Base Elmendorf-Richardson (JBER). The proposed project qualified as an undertaking under Section 106 of the National Historic Preservation Act (NHPA; 16 United States Code [USC] Section 470, as amended 1992) as the project included federal lands and federal funds; therefore, an identification-phase cultural resources survey of the project area was planned and completed in 2014. This document details that survey.
The biology of Blumeria effector candidates
Creators: name: Bonciani, Giulia
Publisher: name: Imperial College London
Year: 2013

description: Blumeria graminis f.sp. hordei is an obligate biotrophic fungus which causes the powdery mildew disease on barley. It is generally accepted that the specialized feeding structure called the haustorium secretes effector proteins that suppress and modulate the host defense responses. I used transmission electron microscopy to successfully obtain electron micrographs of the ultrastructure of the B. graminis f.sp. hordei infection, including the haustoria, in barley leaves. Effector proteins typically show signatures of positive diversifying selection as a result of the coevolutionary struggle between hosts and pathogens. In this thesis, the ratio of nonsynonymous to synonymous substitutions in Blumeria Effector Candidate (BEC) genes among 54 isolates was calculated to detect BECs under positive diversifying selection. Polymorphisms were found in the BEC genes but the small sample size tested was too small to detect statistically significant positive diversifying selection. In parallel to research carried out in this thesis, a panel of fifty Blumeria candidate effector (BEC) proteins was screened using host-induced gene silencing (HIGS). Of these fifty candidates, eight reduced the haustoria development and are considered as virulence effectors: BEC1005, BEC1011, BEC1016, BEC1018, BEC1019, BEC1038, BEC1040 and BEC1054. I measured relative abundance of RNA in nine BECs including the eight BECs confirmed to be virulence effectors by qRT-PCR at six time points of infection. The transcript profiling presented here reveals that some BECs are important during the early stages of the infection when the compatibility of the host-pathogen interaction is being established and other BECs play a role during the later stages of the infection that involve biotrophy maintenance. It has been proposed that the roles of BEC1011 and BEC1054 in infection are related to host RNA binding or another function that evolved from a ribonuclease ancestor. I used the differential scanning fluorimetry method to test whether BEC1054 binds RNA. The findings in this thesis reveal that there is binding between BEC1054 and RNA and RNA has a destabilizing effect on BEC1054. To further investigate their role in virulence, BEC1011 and BEC1054 transgenic wheat lines were created at NIAB. I commenced the genotyping of these transgenic lines and preliminary pathogenicity tests with some homozygous BEC1011- and BEC1054-wobble lines and homozygous null lines. The preliminary results presented here show that there is a visibly increased amount of sporulating conidia on homozygous BEC1011- and BEC1054-wobble lines compared with homozygous null lines.

description: SAX J1748.9-2021 is an accreting X-ray millisecond pulsar observed in outburst five times since its discovery in 1998. In early October 2017, the source started its sixth outburst, which lasted only ~13 days, significantly shorter than the typical 30 days duration of the previous outbursts. It reached a 0.3-70 keV unabsorbed peak luminosity of $\sim3\times10^{36}$ erg/s. This is the weakest outburst ever reported for this source to date. We analyzed almost simultaneous XMM-Newton, NuSTAR and INTEGRAL observations taken during the decaying phase of its 2017 outburst. We found that the spectral properties of SAX J1748.9-2021 are consistent with an absorbed Comptonization plus a blackbody component. The former, characterized by an electron temperature of ~20 keV, a photon index of ~1.6-1.7 keV and seed photon temperature of 0.44 keV, can be associated to a hot corona or the accretion column, while the latter is more likely originating from the neutron star surface (kT$_{bb}\sim0.6$ keV, R$_{bb}\sim2.5$ km). These findings suggest that SAX J1748.9-2021 was observed in a $hard$ spectral state, as it is typically the case for accreting millisecond pulsars in outburst.

description: We have investigated the variability of the binary X-ray pulsar, SMC X-1, in data from several X-ray observatories. We confirm the ~60-day cyclic variation of the X-ray flux in the long-term monitoring data from the RXTE and CGRO observatories. X-ray light curves and spectra from the ROSAT, Ginga, and ASCA observatories show that the uneclipsed flux varies by as much as a factor of twenty between a high-flux state when 0.71 second pulses are present and a low-flux state when pulses are absent. In contrast, during eclipses when the X-rays consist of radiation scattered from circumsource matter, the fluxes and spectra in the high and low states are approximately the same. These observations prove that the low state of SMC X-1 is not caused by a reduction in the intrinsic luminosity of the source, or a spectral redistribution thereof, but rather by a quasi-periodic blockage of the line of sight, most likely by a precessing tilted accretion disk. In each of two observations in the midst of low states a brief increase in the X-ray flux and reappearance of 0.71 second pulses occurred near orbital phase 0.2. These brief increases result from an opening of the line of sight to the pulsar that may be caused by wobble in the precessing accretion disk. The records of spin up of the neutron star and decay of the binary orbit are extended during 1991-1996 by pulse-timing analysis of ROSAT, ASCA, and RXTE PCA data. The pulse profiles in various energy ranges from 0.1 to >21 keV are well represented as a combination of a pencil beam and a fan beam. Finally, there is a marked difference between the power spectra of random fluctuations in the high-state data from the RXTE PCA below and above 3.4 keV. Deviation from the fitted power law around 0.06 Hz may be QPO.

description: We address the generalized uncertainty principle in scenarios of successive measurements. Uncertainties are characterized by means of generalized entropies of both the Rényi and Tsallis types. Here, specific features of measurements of observables with continuous spectra should be taken into account. First, we formulated uncertainty relations in terms of Shannon entropies. Since such relations involve a state-dependent correction term, they generally differ from preparation uncertainty relations. This difference is revealed when position is measured by the first. In contrast, state-independent uncertainty relations in terms of Rényi and Tsallis entropies are obtained with the same lower bounds as in the preparation scenario. These bounds are explicitly dependent on the acceptance function of apparatuses in momentum measurements. Entropic uncertainty relations with binning are discussed as well.

Functional analysis of the type IV pilus assembly machinery in Neisseria meningitidis
Creators: name: Georgiadou, Michaella
Publisher: name: Imperial College London
Year: 2013

description: Type IV pili (Tfp) are one of the most widespread virulence factors in prokaryotes. Their inherent capacity to mediate an astonishing array of functions differentiates them from other pili and contributes to the pathogenesis of many important human pathogens. Previous intensive efforts by our group in Neisseria meningitidis identified 23 proteins dedicated to Tfp biology, 15 of which are essential for pilus biogenesis. Though these proteins are widely accepted to exert their functions within a large multiprotein complex, the mechanisms governing the biogenesis and functionality of these organelles remained poorly defined. Consequently, the first objective of my project was to perform a large-scale analysis to identify fundamental interactions between 11 Pil proteins from N. meningitidis. To achieve this, we employed the bacterial adenylate cyclase two-hybrid system, which uncovered 20 different binary interactions, many of which are novel and represents the most complex interaction network between Pil proteins reported to date. Significantly, this study revealed that PilE, PilM, PilN and PilO involved in pilus assembly, indeed interact and provided us with a strong foundation to proceed to our main objective, which was to perform a detailed functional analysis of this poorly characterized subcomplex. Using a battery of assays we determined the membrane topology of PilN and PilO, mapped the interaction domains between PilE, PilM, PilN and PilO, and showed that a widely conserved N-terminal motif in PilN is essential for both PilM-PilN interactions and pilus assembly. Furthermore, we established by stability and co-immunoprecipitation studies that PilP (another protein involved in pilus assembly) forms a complex with PilM, PilN and PilO. Finally, we attempted to reconstitute a minimal Tfp assembly machinery in E. coli, however these efforts necessitate further improvements. Taken together, this study has shed light on the molecular mechanisms of Tfp biology and provides a useful blueprint for future studies.

description: To assess atrial fibrillation risk factors in people with HIV, we identified incident atrial fibrillation in a large clinical cohort of people receiving care. Compared with 970 controls without atrial fibrillation, the 97 with adjudicated incident atrial fibrillation were older, less likely Hispanic, and had more coronary disease, heart failure, and chronic obstructive pulmonary disease. In multivariable analysis, nonuse of antiretroviral therapy and prescription of antiretroviral regimens with multiple core agents were associated with increased atrial fibrillation risk.
Thermophysical properties of industrial fluids at high pressures from sound speed and density measurements
Creators: name: Lin, Chih-Wei
Publisher: name: Imperial College London
Year: 2013

description: The objective of this project was to provide reliable thermophysical property data, mainly density and sound speed, for industrial and academic use. This thesis investigates in detail the speed of sound and density of several industrial fluids at pressure up to 400 MPa and temperature from 248 K to 473 K. The experimental technique used was based on an ultrasonic cell implementing a double-path pulse-echo method with an ultrasound transducer placed between two unequally-spaced reflectors. The cell was calibrated in water at T = 298.15 K and p = 1 MPa against the speed of sound given by the 1995 equation-of-state formulation of the International Association for the Properties of Water and Steam (IAPWS-95) which, for that state point, has an uncertainty of ± 0.005 %. In this thesis, the ultrasonic cell was validated by water measurement over a wide range of temperature and pressure and was shown to have an uncertainty of ± 0.03 %. The uncertainty of the sound speed measurement for other fluids in general is less than 0.1 %. In addition, a densimeter was also used. The measured sound speed and density combined with the heat capacity can be used to develop advanced analytical equations of state and derive all of the thermodynamic properties for key mixtures by numerical-integration algorithms. All the thermophysical properties measured in this thesis were correlated into equations as a function of temperature and pressure. The correlated parameters were calculated by regression analysis in Microsoft Excel. The regression function is used to minimize the sum of squares of error of all the data which needs to be fitted into an equation. In our regression analysis from Excel, the objective was to fit the data to within the target uncertainty using the number of parameters required. Several working fluids were studied: pure water, hexafluoropropene (HFP), trifluoro-3-(trifluoromethyl)oxirane (common name hexafluoropropylene oxide, HFPO), carbon dioxide, and carbon dioxide + propane mixtures. The results extend our understanding of the thermophysical properties of these key industrial fluids and may lead to the development of improved thermodynamic models for application in air conditioning, refrigeration system and carbon capture and storage applications.

description: It is shown that a zero curvature representation for $D$-- dimensional $p$-- brane equations of motion originates naturally in the geometric (Lund- Regge- Omnes) approach. To study the possibility to use this zero curvature representation for investigation of nonlinear equations of $p$-- branes, the simplest case of $D$-- dimensional string ($p=1$) is considered. The connection is found between the $SO(1,1)$ gauge (world--sheet Lorentz) invariance of the string theory with a nontrivial dependence on a spectral parameter of the Lax matrices associated with the nonlinear equations describing the embedding of a string world sheet into flat $D$-- dimensional space -- time. Namely, the spectral parameter can be identified with a parameter of constant $SO(1,1)$ gauge transformations, after the deformation of the Lax matrices has been performed.

description: Introduction: Several drugs were explored for their utility in treating nausea and vomiting in pregnancy (NVP). The present study is a network meta-analysis of such drugs. Methods: Electronic databases were searched for randomized clinical trials that have compared active interventions (with placebo or other active interventions) for treating NVP. Nausea scores were the primary outcome and changes in nausea scores, emetic episodes, adverse events, and vomiting control were the key secondary outcomes. Weighted mean difference was the effect estimate for continuous variable and odds ratio for the numerical variable. Random-effects model was used and the strength of the evidence was graded. Results: Fifty studies were included in the systematic review and 42 in the meta-analysis. Acupuncture, chamomile, dimenhydrinate, doxylamine/vitamin B6, ginger, quince, metoclopramide, and vitamin B6 were associated with reduced nausea scores compared to placebo. Of these interventions, ginger and vitamin B6 were also associated with better vomiting control and less incidence of adverse events. Adequate evidence supporting the use exists only for ginger and the quality of evidence for this comparison is moderate. Strength of evidence for all other comparisons is very low. Conclusion: Present evidence is conclusive on the therapeutic benefits of ginger in treating NVP. Although favorable results were obtained for several other interventions, the strength of evidence is very low. The results of this network meta-analysis should be interpreted with extreme caution as it might change with the advent of data from future head-to-head clinical trials.

description: Identifying individuals at high risk of missing HIV care provider visits could support proactive intervention. Previous prediction models for missed visits have not incorporated data beyond the individual level. Methods: We developed prediction models for missed visits among people with HIV (PWH) with ≥1 follow-up visit in the Center for AIDS Research Network of Integrated Clinical Systems from 2010 to 2016. Individual-level (medical record data and patient-reported outcomes), community-level (American Community Survey), HIV care site-level (standardized clinic leadership survey), and structural-level (HIV criminalization laws, Medicaid expansion, and state AIDS Drug Assistance Program budget) predictors were included. Models were developed using random forests with 10-fold cross-validation; candidate models with the highest area under the curve (AUC) were identified. Results: Data from 382 432 visits among 20 807 PWH followed for a median of 3.8 years were included; the median age was 44 years, 81% were male, 37% were Black, 15% reported injection drug use, and 57% reported male-to-male sexual contact. The highest AUC was 0.76, and the strongest predictors were at the individual level (prior visit adherence, age, CD4+ count) and community level (proportion living in poverty, unemployed, and of Black race). A simplified model, including readily accessible variables available in a web-based calculator, had a slightly lower AUC of. 700. Conclusions: Prediction models validated using multilevel data had a similar AUC to previous models developed using only individual-level data. The strongest predictors were individual-level variables, particularly prior visit adherence, though community-level variables were also predictive. Absent additional data, PWH with previous missed visits should be prioritized by interventions to improve visit adherence.
Behaviour and design of steel fibre reinforced concrete slabs
Creators: name: Oikonomou-Mpegetis, Sotirios
Publisher: name: Imperial College London
Year: 2013

description: Using Steel Fibre Reinforced Concrete (SFRC) can bring substantial benefits to the construction industry of which savings in construction time and labour are most significant. In addition, steel fibres enhance crack control particularly when acting in conjunction with reinforcement bars. Despite the aforementioned benefits of SFRC, there is a still a lack of consensus on the principles that should be adopted in its design. Currently, a number of different test methods are used to determine the material properties of SFRC but there is no agreement on which method is best. As a result, steel fibre suppliers claim widely differing properties for similar fibres which leads to confusion amongst designers and in some cases inadequate structural performance. This research considers the design of SFRC slabs with emphasis on pile supported slabs which are frequently designed using proprietary methods due to the absence of codified guidance. Key issues in the design of such slabs are control of cracking in service and the calculation of flexural and punching shear resistances. A fundamental challenge is that SFRC exhibits a strain softening response at the dosages commonly used in slabs. At present, the yield line method is generally considered most suitable for designing such slabs at the ultimate limit state but there is a lack of consensus on the design moment of resistance as the bending moment along the yield lines reduces with increasing crack width. This thesis investigates these matters using a combination of experimental and theoretical work. The experimental work compares material properties derived from notched beam and round plate tests and seeks to determine a relationship between the two. Tests were also carried out on continuous slabs with the same material properties as used in the notched beam and round plate tests. Round plate tests were also carried out to determine the contribution of steel fibres to punching shear resistance. The theoretical work investigates the applicability of yield line analysis to the design of SFRC slabs using a combination of numerical modelling and design oriented analytical models. Design for punching shear and the serviceability limit state of cracking are also considered.

description: The cosmic-ray lithium and beryllium ($^{6}$Li, $^{7}$Li, $^{7}$Be, $^{9}$Be, $^{10}$Be) isotopic composition has been measured with the satellite-borne experiment PAMELA, which was launched into low-Earth orbit on-board the Resurs-DK1 satellite on June 15th 2006. The rare lithium and beryllium isotopes in cosmic rays are believed to originate mainly from the interaction of high energy carbon, nitrogen and oxygen nuclei with the interstellar medium (ISM), but also on "tertiary" interactions in the ISM (i.e. produced by further fragmentation of secondary beryllium and boron). In this paper the isotopic ratios $^{7}$Li/$^{6}$Li and $^{7}$Be/($^{9}$Be + $^{10}$Be) measured between 150 and 1100 MeV/n using two different detector systems from July 2006 to September 2014 will be presented.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We present exact solutions to the quantum few-electron problem as applied to the uniform electron gas model of electronic structure theory. Our core methodology uses a Sum-of-Products (SOP) representation of singular potentials to make the fully correlated multi-particle quantum mechanical problem computationally tractable. With full access to periodic digital wave functions, we analyze the exchange-correlation, spin symmetry, and thermodynamic (T = 0K) phase for an electron gas with up to 4 electrons per unit volume. We also present pure-spin exchange-correlation functionals for the same few-electron solutions. Consistent with quantum Monte Carlo results, we observe a transition from a Fermi fluid at high density where the kinetic term dominates to a localized BCC Wigner crystal at low density where correlation effects dominate. By tracking the symmetry, we note that the 3-electron gas transits from a S = 1/2 spin doublet Fermi fluid at high-density to a S = 3/2 spin quartet at low-density forming a localized spin-density wave.
Prediction of nonlinear nonstationary time series data using a digital filter and support vector regression

description: Volatility is a key parameter when measuring the size of the errors made in modelling returns and other nonlinear nonstationary time series data. The Autoregressive Integrated Moving- Average (ARIMA) model is a linear process in time series; whilst in the nonlinear system, the Generalised Autoregressive Conditional Heteroskedasticity (GARCH) and Markov Switching GARCH (MS-GARCH) models have been widely applied. In statistical learning theory, Support Vector Regression (SVR) plays an important role in predicting nonlinear and nonstationary time series data. We propose a new class model comprised of a combination of a novel derivative Empirical Mode Decomposition (EMD), averaging intrinsic mode function (aIMF) and a novel of multiclass SVR using mean reversion and coefficient of variance (CV) to predict financial data i.e. EUR-USD exchange rates. The proposed novel aIMF is capable of smoothing and reducing noise, whereas the novel of multiclass SVR model can predict exchange rates. Our simulation results show that our model significantly outperforms simulations by state-of-art ARIMA, GARCH, Markov Switching generalised Autoregressive conditional Heteroskedasticity (MS-GARCH), Markov Switching Regression (MSR) models and Markov chain Monte Carlo (MCMC) regression.

description: Introduction: Little is known about onward HIV transmissions from people living with HIV (PLWH) in care. Antiretroviral therapy (ART) has increased in potency, and treatment as prevention (TasP) is an important component of ending the epidemic. Syndemic theory has informed modelling of HIV risk but has yet to inform modelling of HIV transmissions. Methods: Data were from 61,198 primary HIV care visits for 14,261 PLWH receiving care through the Centers for AIDS Research (CFAR) Network of Integrated Clinical Systems (CNICS) at seven United States (U.S.) sites from 2007 to 2017. Patient-reported outcomes and measures (PROs) of syndemic conditions – depressive symptoms, anxiety symptoms, drug use (opiates, amphetamines, crack/cocaine) and alcohol use – were collected approximately four to six months apart along with sexual behaviours (mean = 4.3 observations). Counts of syndemic conditions, HIV sexual risk group and time in care were modelled to predict estimated HIV transmissions resulting from sexual behaviour and viral suppression status (HIV RNA < 400/mL) using hierarchical linear modelling. Results: Patients averaged 0.38 estimated HIV transmissions/100 patients/year for all visits with syndemic conditions measured (down from 0.83, first visit). The final multivariate model showed that per 100 patients, each care visit predicted 0.05 fewer estimated transmissions annually (95% confidence interval (CI): 0.03 to 0.06; p < 0.0005). Cisgender women, cisgender heterosexual men and cisgender men of undisclosed sexual orientation had, respectively, 0.47 (95% CI: 0.35 to 0.59; p < 0.0005), 0.34 (95% CI: 0.20 to 0.49; p < 0.0005) and 0.22 (95% CI: 0.09 to 0.35; p < 0.005) fewer estimated HIV transmissions/100 patients/year than cisgender men who have sex with men (MSM). Each within-patient syndemic condition predicted 0.18 estimated transmissions/100 patients/year (95% CI: 0.12 to 0.24; p < 0.0005). Each between-syndemic condition predicted 0.23 estimated HIV transmissions/100 patients/year (95% CI: 0.17 to 0.28; p < 0.0005). Conclusions: Estimated HIV transmissions among PLWH receiving care in well-resourced U.S. clinical settings varied by HIV sexual risk group and decreased with time in care, highlighting the importance of TasP efforts. Syndemic conditions remained a significant predictor of estimated HIV transmissions notwithstanding the effects of HIV sexual risk group and time in care.

description: We report on observations of the fading optical counterpart of the gamma-ray burst GRB 970228, made on 4~September~1997 using the STIS CCD on the Hubble Space Telescope. The unresolved counterpart is detected at V=28 +/- 0.25, consistent with a continued power-law decline with exponent -1.14 +/- 0.05. No proper motion is detected, in contradiction of an earlier claim. The counterpart is located within, but near the edge of, a faint extended source with diameter ~0."8 and integrated magnitude 25.7 +/- 0.25. Comparison with WFPC2 data taken one month after the initial burst and NTT data taken on March 13 shows no evidence for fading of the extended emission. After adjusting for the probable Galactic extinction in the direction of GRB 970228 of A_v=0.7, we find that the observed nebula is consistent with the sizes of galaxies of comparable magnitude found in the Hubble Deep Field and other deep HST images, and that only 2% of the sky is covered by galaxies of similar or greater surface brightness. We therefore conclude that the extended source observed about GRB 970228 is most likely a galaxy at moderate redshift, and is almost certainly the host of the gamma-ray burst.

Inhibition of HCV Replication by Host Cell Innate Antiviral Defences

Publisher: name: Imperial College London

description: RIG-I and MDA5 are the major intracellular sensors for the induction of IFN-β, by dsRNA, in Huh7 cells. It was found that the expression of RIG-I, MDA5 and the signalling mediators TRIF, MAVS and MyD88 were upregulated in Huh7 HCV RNA replicon cells. Similar findings were obtained in Huh7 cells infected with JFH-1 HCV. When replicon and HCV infected cells were further stimulated by dsRNA the induction of these genes were reduced compare to control cells. The expression of NS3 and NS3/4A proteins, using adenovirus vectors, reduced RIG-I, MDA5, MAVS and MyD88 expression levels in response to dsRNA stimulation. Ablation of MDA5, MAVS, MyD88 and TRIF in HCV infected Huh7.5 cells, using siRNAs, increased virus replication demonstrating their importance in inhibiting HCV infection. These results show that HCV inhibits the induction of interferon in response to dsRNA and that NS3 plays an important role in this inhibition. Analysis of gene expression during HCV infection showed significant changes in the expression of genes involved in the innate immune response, interferon, apoptosis and cell cycle regulation pathways. These include SOCS1, 2 and 3, OAS3, MXA1, IRF9, IRF1, IFNAR2 and STAT1. SOCS3 knockdown by siRNAs reduced HCV replication indicating an additional mechanism of IFN inhibition by HCV. Infection with HCV also caused cell cycle arrest leading to DNA fragmentation and apoptosis. A decrease in cyclin B1 and an increase in GADD45-β expression during HCV infection indicates that they may play an important role in HCV induced alterations to the cell cycle.
