description: The 31P-NMR (nuclear magnetic resonance) and muSR (muon spin relaxation) measurements on the filled skutterudite system SmFe4P12 have been carried out. The temperature T dependence of the 31P-NMR spectra indicates the existence of the crystalline electric field effect splitting of the Sm3+$ (J = 5/2) multiplet into a ground state and an excited state of about 70 K. The spin-lattice relaxation rate 1/T1 shows the typical behavior of the Kondo system, i.e., 1/T1 is nearly T independent above 30 K, and varies in proportion to T (the Korringa behavior, 1/T1 \propto T) between 7.5 K and 30 K. The T dependence deviated from the Korringa behavior below 7 K, which is independent of T in the applied magnetic field of 1 kOe, and suppressed strongly in higher fields. The behavior is explained as 1/T1is determined by ferromagnetic fluctuations of the uncovered Sm3+ magnetic moments by conduction electrons. The muSR measurements in zero field show the appearance of a static internal field associated with the ferromagnetic order below 1.6 K.

description: This study aimed to evaluate the safety and efficacy of rivaroxaban in preventing portal vein system thrombosis (PVST) in patients with liver cirrhosis after splenectomy and pericardial devascularization. 70 cirrhotic patients undergoing splenectomy and pericardial devascularization were randomly assigned to rivaroxaban treatment (n=35) or low-molecular weight heparin (LMWH) plus warfarin treatment (n=35) for 30 days in this randomized controlled trial. The primary endpoint is the PVST formation. Ultrasound doctors and radiologists were blinded to the randomization results. Both groups received routine outpatient inspection every month and were followed for one year. 17 patients (48.6 %) in rivaroxaban group developed PVST, compared with 27 patients (77.1 %) in LMWH plus warfarin group (P=0.025). The incidence of PVST during the first year postoperation was significantly lower in rivaroxaban group than in LMWH plus warfarin group (F=7.901, P=0.006). The intra-group comparisons versus baseline showed the liver function improved from POD 21 to POM 1, and coagulation function improved from POM 2, in rivaroxaban group. In contrast, the liver function improved from POM 1 to POM 2, and coagulation function improved from POM 4, in LMWH plus warfarin group. The prophylactic use of rivaroxaban significantly decreases the incidence of PVST after splenectomy and pericardial devascularization in cirrhotic patients compared to LMWH plus warfarin treatment. Besides, rivaroxaban treatment was safe and effective and associated with better liver and coagulation functions improvement than LMWH plus warfarin treatment.

description: We study the effects of anisotropic order parameters on the temperature dependence of London penetration depth anisotropy $γ_λ(T)$. After MgB$_2$, this dependence is commonly attributed to distinct gaps on multi-band Fermi surfaces in superconductors. We have found, however, that the anisotropy parameter may depend on temperature also in one-band materials with anisotropic order parameters $Δ(T,k_F)$, a few such examples are given. We have found also that for different order parameters, the temperature dependence of $Δ(T)/Δ(0)$ can be represented with good accuracy by the interpolation suggested by D. Einzel, J. Low Temp. Phys, {\bf 131}, 1 (2003), which simplifies considerably the evaluation of $γ_λ(T)$. Of particular interest is mixed order parameters of two symmetries for which $γ_λ(T)$ may go through a maximum for a certain relative weight of two phases. Also, for this case, we find that the ratio $Δ_{max}(0)/T_c$ may exceed substantially the weak coupling limit of 1.76. It, however, does not imply a strong coupling, rather it is due to significantly anisotropic angular variation of $Δ$.

description: The propagation of a domain wall in a submicron ferromagnetic spin-valve stripe is investigated using giant magnetoresistance. A notch in the stripe efficiently traps an injected wall stopping the domain propagation. The authors show that the magnetic field at which the wall is depinned displays a stochastic nature. Moreover, the depinning statistics are significantly different for head to head and tail-to-tail domain walls. This is attributed to the dipolar field generated in the vicinity of the notch by the pinned layer of the spin-valve.

description: We introduce a notion of positive pair of contact structures on a 3-manifold which generalizes a previous definition of Eliashberg-Thurston and Mitsumatsu. Such a pair gives rise to a locally integrable plane field $λ$. We prove that if $λ$ is uniquely integrable and if both structures of the pair are tight, then the integral foliation of $λ$ doesn't contain any Reeb component whose core curve is homologous to zero. Moreover, the ambient manifold carries a Reebless foliation. We also show a stability theorem "à la Reeb" for positive pairs of tight contact structures.

description: Motivated by the irregular and little-understood morphologies of z ~ 2 - 3 galaxies, we use non-parametric coefficents to quantify the morphologies of 216 galaxies which have been spectroscopically confirmed to lie at redshifts z = 1.8 - 3.4 in the GOODS-N field. Using measurements of ultraviolet (UV) and optical spectral lines, multi-band photometric data, and stellar population models we statistically assess possible correlations between galaxy morphology and physical observables such as stellar mass, star formation rate, and the strength of galaxy-scale outflows. We find evidence that dustier galaxies have more nebulous UV morphologies and that larger, more luminous galaxies may drive stronger outflows, but otherwise conclude that UV morphology is either statistically decoupled from the majority of physical observables or determined by too complex a combination of physical processes to provide characterizations with predictive power. Given the absence of strong correlations between UV morphology and physical parameters such as star formation rates, we are therefore unable to support the hypothesis that morphologically irregular galaxies predominantly represent major galaxy mergers. Comparing galaxy samples, we find that IR-selected BzK galaxies and radio-selected submillimeter galaxies (SMGs) have UV morphologies similar to the optically selected sample, while distant red galaxies (DRGs) are more nebulous.

Chemical studies on the origin of secondary metabolites in selected marine invertebrates

Publisher: name: University of British Columbia
Year: 2009

description: Precursor incorporation experiments with several widespread species of Northeastern Pacific Ocean dorid nudibranchs have led to the conclusion that each species studied is capable of de novo biosynthesis. Incorporation studies with [1,2- 1 3C2] acetate, [l,2-13C2,18Oi] acetate, and [2-13C] mevalonate were used to demonstrate the biosynthesis of the sesquiterpenoid albicanyl acetate (18), and the sesterterpenoids cadlinaldehyde (19) and luteone (20) by Cadlina luteomarginata. Quantitative analysis of C NMR data showed that only a small turnover of metabolite took place but that the newly formed molecules had extremely high levels of label incorporation. As a by-product of the examination of biosynthesized metabolites of C. luteomarginata, a novel diterpenoid metabolite, seco-spongian 22, was isolated and identified. [Chemical models not reproduced] A study of Californian specimens of C. luteomarginata indicated that the three biosynthesized metabolites are present across its geographic range. Examination of individual C. luteomarginata specimens from one B.C. population revealed significant variation in metabolite concentration between individuals and between tissues of each individual. Incorporation experiments with [1,2- 1 3C2] acetate were also used to demonstrate the de novo biosynthesis of acanthodoral (28) by Acanthodoris hudsoni, a metabolite previously known only from the related nudibranch A. nanaimoensis. Attempts to incorporate 180 labels into the aldehyde oxygen atoms of nanaimoal (24), isoacanthodoral (27), and 28 in these two species revealed that the aldehyde oxygens are not retained in the biosynthesis. [Chemical models not reproduced] De novo biosynthesis of the 3-hydroxybutyrate side chain of diaulusterol A (34) in Diaulula sandiegensis was proven by incorporation of [1,2- C2]acetate. None of [1,2- 13C2] acetate, [2-14C] mevalonate, and [4-14C]cholesterol was successfully incorporated in the steroid portion of 34. Synthesis of [2,l'-13C2]disodium 2-ethylmalonate and [2,3-13C2] sodium butyrate followed by injection into the nudibranch Triopha catalinae demonstrated that T. catalinae utilizes butyrate in the processive polyketide biosynthesis of triophamine (43). This represented the first proven use of butyrate in polyketide biosynthesis by a marine invertebrate. [Chemical model not reproduced] Investigation of the extracts of the North Sea flatworm Prostheceraeus vUlatus and its prey, the ascidian Clavelina lepadiformis, revealed the presence of one known and four novel secondary metabolites: the decahydroquinoline alkaloid lepadins A, B, and C and pyrrolidine alkaloid villatamines A and B.P. villatus concentrates the alkaloids from its diet, analogous to the relationship between many shell-less molluscs and their algal or sponge dietary organisms.
Vertex model instabilities for tissues subject to cellular activity or applied stresses

description: The vertex model is widely used to describe the dynamics of epithelial tissues, because of its simplicity and versatility and the direct inclusion of biophysical parameters. Here, it is shown that quite generally, when cells modify their equilibrium perimeter due to their activity, or the tissue is subject to external stresses, the tissue becomes unstable with deformations that couple pure-shear or deviatoric modes, with rotation and expansion modes. For short times, these instabilities deform cells increasing their ellipticity while, at longer times, cells become non-convex, indicating that the vertex model ceases to be a valid description for tissues under these conditions. The agreement between the analytic calculations performed for a regular hexagonal tissue and the simulations of disordered tissues is excellent due to the homogenization of the tissue at long wavelengths.

description: We discuss finite regions of the deconfining phase of a confining gauge theory (plasma balls/kinks) as solitons of the large $N$, long wavelength, effective Lagrangian of the thermal gauge theory expressed in terms of suitable order parameters. We consider a class of confining gauge theories whose effective Lagrangian turns out to be a generic 1 dim. unitary matrix model. The dynamics of this matrix model can be studied by an exact mapping to a non-relativistic many fermion problem on a circle. We present an approximate solution to the equations of motion which corresponds to the motion (in Euclidean time) of the Fermi surface interpolating between the phase where the fermions are uniformly distributed on the circle (confinement phase) and the phase where the fermion distribution has a gap on the circle (deconfinement phase). We later self-consistently verify that the approximation is a good one. We discuss some properties and implications of the solution including the surface tension which turns out to be positive. As a by product of our investigation we point out the problem of obtaining time dependent solutions in the collective field theory formalism due to generic shock formation.

STREAM OF CONSCIOUSNESS NARRATION IN VIRGINIA WOOLF
Creators: name: Cochran-Smith, Kelly
Publisher: name: Maryland Shared Open Access Repository
Year: 2012

description: In the Modernist era, writers reflected the disillusionment of their times by rebelling against conventional methods. The intention was not merely to express new content, but to fundamentally change the process by which meaning could be gleaned from this content. Modernist writers such as Virginia Woolf forced readers to redefine and recreate the act of reading. One of the most characteristic techniques these writers employed was 'stream of consciousness,' a term employed to various degrees in both Mrs. Dalloway and The Waves. In analyzing stream-of-consciousness, this paper first delves into the genre's philosophical and psychological influences, with an emphasis on the prespeech levels of consciousness and Bergson's theory of "durational flux." It then examines nonlinear narration in these two works, with a focus on memory, desire and the so-called "Modernist Paradox." Because stream-of-consciousness literally changed the shape of the novel form, this paper next examines the concept of space as a conduit for time, a juxtaposition of internal and external, and also a new definition of "narrative space." An evaluation of the increased emphasis on sound and other sensory input beyond the visual follows, particularly the influence of, and parallels between, stream-of-consciousness and musical forms. Ultimately, this paper argues that the myriad impressions conveyed in stream-of-consciousness literature, particularly that of Virginia Woolf, is represented in the subjective meaning-making.

description: This paper presents a BPD (Balanced Power Dissipation) heuristic scheduling algorithm applied to VLSI CMOS digital circuits/systems in order to reduce the global computational demand and provide balanced power dissipation of computational units of the designed digital VLSI CMOS system during the task assignment stage. It results in reduction of the average and peak temperatures of VLSI CMOS digital circuits. The elaborated algorithm is based on balanced power dissipation of local computational (processing) units and does not deteriorate the throughput of the whole VLSI CMOS digital system.

description: Our grand challenges in science are those for which we cannot ignore the complexity of the world--the interconnectedness of our disciplines, systems, and groups.

 

How do we embrace complexity in the project of scientific discovery? This is perhaps the threshold question for our moment in the Earth and Space Sciences. We will use the lens of network science in outlining the tools, technologies, processes, and literacies required to embrace complexity and make frontier scientific discovery. We will present studies from across contexts that use network science to respond to 'wicked problems' as well as to study social interactions and communities.

 

We will explore how networks might provide insight into the flourishing of science and scientific communities, ultimately sharing new network science research into scientific progress and community that suggest principles of flourishing. We will create a conversation around a new kind of science of 'flourishing studies.'
Non-dissipative tidal synchronization in accreting binary white dwarf systems

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: We study a non-dissipative hydrodynamical mechanism that can stabilize the spin of the accretor in an ultra-compact double white dwarf binary. This novel synchronization mechanism relies on a nonlinear wave interaction spinning down the background star. The essential physics of the synchronization mechanism is summarized as follows. As the compact binary coalesces due to gravitational wave emission, the largest star eventually fills its Roche lobe and accretion starts. The accretor then spins up due to infalling material and eventually reaches a spin frequency where a normal mode of the star is resonantly driven by the gravitational tidal field of the companion. If the resonating mode satisfies a set of specific criteria, which we elucidate in this paper, it exchanges angular momentum with the background star at a rate such that the spin of the accretor locks at this resonant frequency, even though accretion is ongoing. Some of the accreted angular momentum that would otherwise spin up the accretor is fed back into the orbit through this resonant tidal interaction. Two modes capable of stabilizing the accretor's spin are the l=4,m=2 and l=5,m=3 CFS unstable hybrid r-modes, which stabilize the spin of the accretor at frequency 2.6 and 1.5 times the binary's orbital frequency respectively. Since the stabilization mechanism relies on continuously driving a mode at resonance, its lifetime is limited since eventually the mode amplitude saturates due to non-linear mode-mode coupling. Rough estimates of the lifetime of the effect lie from a few orbits to millions of years.

description: We present an extension of our construction (hep-th/0606199) exhibiting $SO(4)\times SO(2)$ symmetry. We extend the previously presented ansatz by introducing a U(1) gauge field. The presence of the gauge field allows for more general values of the Killing spinor U(1) charge. One more time we identify a four dimensional Kahler structure and a Monge-Ampere type of equation parametrized by the U(1) Killing spinor charge. In addition we identify 2 scalars that parametrize the supersymmetric solutions, one of which is the Kahler potential.

description: We performed the first light curve analysis of GW Leo and a new ephemeris is obtained for QT Boo. In the present photometric study of two contact binary systems, we found that the period of these binary systems is decreasing at a rate of dp/dt=-6.21*10^(-3) days yr^(-1) for GW Leo, and dp/dt=-4.72*10^(-3) days yr^(-1) for QT Boo, respectively. The light curve investigation also yields that the system GW Leo is a contact W UMa eclipsing binary with a photometric mass ratio of q=0.881+-0.030, a fillout factor of f=3%, and an inclination of 54.060+-0.066 deg. Due to the O'Connell effect which is known as asymmetries in the light curves' maxima, a cold spot is employed along with the solution. We also calculate the distance of GW Leo from the distance modulus formula as 465.58+-23 pc, which is relatively close to the quantity measured by the Gaia DR2 using the binary systems' parallax. Moreover, the positions of their components on the H-R diagram are represented.

description: Deeply dissatisfied with the student revolution and its ability to challenge Germany’s status quo, the avant-garde poet Rolf Dieter Brinkmann parted ways with the movement after a brief period of mutual sympathy and support. Leaving the political sphere of mass protest behind, he turned his sole attention to the aesthetic realm and sought to ›revive‹ literature after its proclaimed death. This article offers an in-depth re-reading of the titular poems of Brinkmann’s lyrical magnum opus, Westwärts 1 & 2. The article argues that the author rethought the streets as a place where interventions into mediated life could be waged during a post-revolutionary period characterized by political standstill. Reading Westwärts and Westwärts 2 reveals that Brinkmann’s texts vehemently warn against the incorporation of art into the spectacle of mass media and at the same time comment on the ›failure‹ of ’68.

description: We present a phase-coherent timing analysis of the intermittent accreting millisecond pulsar SAX J1748.9-2021. A new timing solution for the pulsar spin period and the Keplerian binary orbital parameters was achieved by phase connecting all episodes of intermittent pulsations visible during the 2001 outburst. We investigate the pulse profile shapes, their energy dependence and the possible influence of Type I X-ray bursts on the time of arrival and fractional amplitude of the pulsations. We find that the timing solution of SAX J1748.9-2021 shows an erratic behavior when selecting different subsets of data, that is related to substantial timing noise in the timing post-fit residuals. The pulse profiles are very sinusoidal and their fractional amplitude increases linearly with energy and no second harmonic is detected. The reason why this pulsar is intermittent is still unknown but we can rule out a one-to-one correspondence between Type I X-ray bursts and the appearance of the pulsations.

description: Bismuth ferrite is one of the most widely studied multiferroic materials because of its large ferroelectric polarisation coexisting with magnetic order at room temperature. Using density functional theory (DFT), we identify several previously unknown polar and non-polar structures within the low-energy phase space of perovskite-structure bismuth ferrite, BiFeO$_3$. Of particular interest is a series of non-centrosymmetric structures with polarisation along one lattice vector, combined with anti-polar distortions, reminiscent of ferroelectric domains, along a perpendicular direction. We discuss possible routes to stabilising the new phases using biaxial heteroepitaxial strain or interfacial electrostatic control in heterostructures.

Over the full range of galaxy types, masses and brightnesses, and assuming that the gas velocity traces the circular velocity, we find that galaxies obey the relation log(Vcirc/sigma_0)= 0.63-0.11*C28 where C28=5log(r80/r20) and the radii are measured at 80 percent and 20 percent of the total light. Massive galaxies scatter about the Vcirc = sqrt(2)*sigma_0 line for isothermal stellar systems. Disk galaxies follow the simple relation Vcirc/sigma_0=2(1-B/T), where B/T is the bulge-to-total light ratio. For pure disks, C28~2.8, B/T -> 0, and Vcirc~=2*sigma_0. Self-consistent equilibrium galaxy models from Widrow & Dubinski (2005) constrained to match the size-luminosity and velocity-luminosity relations of disk galaxies fail to match the observed Vcirc/sigma_0 distribution. Furthermore, the matching of dynamical models for Vcirc(r)/sigma(r) with observations of dwarf and elliptical galaxies suffers from limited radial coverage and relatively large error bars; for dwarf systems, however, kinematical measurements at the galaxy center and optical edge suggest Vcirc(Rmax) > 2*sigma_0 (in contrast with past assumptions that Vcirc = sqrt(2)*sigma_0 for dwarfs.) The Vcirc-sigma_0-C28 relation has direct implications for galaxy formation and dynamical models, galaxy scaling relations, the mass function of galaxies, and the links between respective formation and evolution processes for a galaxy's central massive object, bulge, and dark matter halo.

description: We present an efficient program for the exact diagonalization solution of the pairing Hamiltonian in spherical systems with rotational invariance based on the SU(2) quasi-spin algebra. The basis vectors with quasi-spin symmetry considered are generated by using an iterative algorithm. Then the Hamiltonian matrix constructed on this basis is diagonalized with the Lanczos algorithm. All non-zero matrix elements of the Hamiltonian matrix are evaluated "on the fly" by the scattering operator and hash search acting on the basis vectors. The OpenMP parallel program thus developed, PairDiagSph, can efficiently calculate the ground-state eigenvalue and eigenvector of general spherical pairing Hamiltonians. Systems with dimension up to 10$^{8}$ can be calculated in few hours on standard desktop computers.

THE ASSOCIATION OF EXPRESSION OF A NOVEL CYCLOPHILIN WITH SUPPRESSED GROWTH AND DIFFERENTIATION OF THE MYELOID LEUKEMIA CELL LINE HL-60

description: Using a newly developed anti-peptide monoclonal antibody, the expression of a novel cyclophilin-like molecule, NK-TR1, in the differentiation of HL-60 promyelocytic leukemia cells was characterized. NK-TR1 was identified in peripheral blood monocytes stimulated with lipopolysaccharide (LPS) and interferon gamma (IFN-y). Unstimulated monocytes demonstrated a low but detectable intracellular level of NK-TR1 protein that increased over 3 days of LPS and IFN-y treatment consistent with the kinetics of monocyte differentiation. Similarly, while the intracellular level of NK-TR1 in untreated promyelocytic HL-60 was low, exposure to 1.2% dimethyl sulfoxide (DMSO), an inducer of granulocytic differentiation, resulted in a marked transient increase in expression that returned to basal levels before the development of differentiation-associated biochemical changes. Phorbol myristate acetate, a promoter of monocytic differentiation, also caused a marked increase in NK-TR1 expression over basal levels. Transfection of NK-TR1 antisense cDNA into HL-60 cells suppressed DMSO-mediated growth arrest. In addition, maturation of HL-60 cells to a more mature phenotype as measured by expression of CD16 and the ability to reduce nitroblue tetrazolium dye was clearly diminished in antisense transfectants when compared to controls. These results are consistent with the hypothesis that the NK-TR1 gene product is serving as an important mediator in a signaling pathway initiated by differentiation agents.

description: In einem Vortrag auf Einladung der Arbeitsgruppe ›Digital Humanities‹ (Münster, 17.07.2013) erörtert Earl Jeffrey Richards die Möglichkeiten der digitalen Philologie. In seiner historischen Spurensuche stößt er dabei auf Hypertext-Verfahren, die bereits vor mehreren Jahrhunderten in der Theologie und Editionsphilologie zum Einsatz kamen. Er zeichnet nach, dass digitale philologische Arbeitsweisen sich als optimale Lösungen nicht nur bei Editionen und Vergleichsprojekten erweisen, sondern auch eine De-Hierarchisierung der Kanonbildung ermöglichen.

description: Modern hydrodynamical simulations offer nowadays a powerful means to trace the evolution of the X-ray properties of the intra-cluster medium (ICM) during the cosmological history of the hierarchical build up of galaxy clusters. In this paper we review the current status of these simulations and how their predictions fare in reproducing the most recent X-ray observations of clusters. After briefly discussing the shortcomings of the self-similar model, based on assuming that gravity only drives the evolution of the ICM, we discuss how the processes of gas cooling and non-gravitational heating are expected to bring model predictions into better agreement with observational data. We then present results from the hydrodynamical simulations, performed by different groups, and how they compare with observational data. As terms of comparison, we use X-ray scaling relations between mass, luminosity, temperature and pressure, as well as the profiles of temperature and entropy. The results of this comparison can be summarised as follows: (a) simulations, which include gas cooling, star formation and supernova feedback, are generally successful in reproducing the X-ray properties of the ICM outside the core regions; (b) simulations generally fail in reproducing the observed ``cool core'' structure, in that they have serious difficulties in regulating overcooling, thereby producing steep negative central temperature profiles. This discrepancy calls for the need of introducing other physical processes, such as energy feedback from active galactic nuclei, which should compensate the radiative losses of the gas with high density, low entropy and short cooling time, which is observed to reside in the innermost regions of galaxy clusters.

EFFECTS OF A SOLUBLE RECOMBINANT HUMAN CD40 LIGAND ON HUMAN LYMPHOMAGENESIS AND LYMPHOMA GROWTH

description: CD40 is a 55 kDa integral membrane protein that is a member of the nerve growth factor/tumor necrosis factor receptor superfamily. CD40 is present on normal and neoplastic B cells, monocytes, dendritic cells, endothelial cells, and other various carcinoma cell lines. Stimulation of CD40 results in B cell proliferation and differentiation. It is also required for successful isotype switching. CD40 and B cell Ig receptor activation also lead to induction of phenotypic and functional germinal center features present in lymph nodes. The ligand for CD40 (CD4OL, CD154) is present primarily on T cells, although it is also found on platelets and NK cells. A recombinant soluble version of the CD4OL has been produced recently. Soluble recombinant human CD4OL (srhCD4OL) has been demonstrated to be an active ligand to CD40. It has been previously demonstrated that an antibody to CD40 was able to inhibit the proliferation of human B cell lymphomas by "activation induced cell death", a process by which activation of neoplastic but not normal cells leads to apoptosis, necrosis, and/or cell-cycle arrest. The antibody has been able to inhibit the formation of human B cell lymphomas both in vitro and in vivo. Most antibodies directed towards human determinants are of murine origin. Mouse antibodies can generate human anti-mouse antibodies in a human which lead to inactivation and clearance of the antibodies. For these reasons, srhCD4OL should be a therapeutically superior alternative for the CD40 antibody, as the recombinant ligand is of human origin. The efficacy of a srhCD4OL using both in vitro and in vivo assays was examined. The in vitro experiments demonstrate that srhCD4OL is effective in suppressing growth of an established B cell lymphoma. The inhibition can be augmented with interferon-y. However, srhCD4OL was not effective in inhibiting human EBV-induced lymphomagenesis in vitro, and actually promoted lymphoma development. In agreement with the in vitro assays, srhCD4OL also did not inhibit lymphoma formation in huPBL-SCID mice. Epstein-Barr virus positive human peripheral blood lymphocytes that are given to SCID mice spontaneously develop EBVlymphoproliferative disease. Treatment of these mice with srhCD4OL did increase the engraftment of human PBL in the mice, without increasing the onset of the lymphomas. Other promoters of engraftment increase the incidence of EBV-LPD. Engraftment was confirmed by quantification of human immunoglobulin in the mouse sera and by flow cytometric assessment of human lymphocyte markers on cells removed from the spleen and thymus. These results demonstrate that srhCD4OL is effective in inhibiting aggressive established lymphomas and this is augmented with IFN-y. However, it is not effective as a preventive measure to stop the formation of lymphomas and should be used with caution in instances where the lymphomas can arise.
