description: DNA sequence analysis of the Factor IX gene from a hemophilia B patient (98% Factor IX antigen; less than 0.01 unit/ml clotting activity) has identified a point mutation in exon II. A guanine to adenine transition causes the substitution of a glutamine codon for an arginine codon at -4 in the propeptide of Factor IX. This variant, termed Factor IX San Dimas, circulates in the plasma as proFactor IX with a mutant 18-amino acid propeptide still attached. Like Factor IX Cambridge (Arg-1----Ser), Factor IX San Dimas is unable to express metal-induced epitopes recognized by conformation-specific polyclonal antibodies. Amino acid analysis of the alkaline hydrolysate indicates that purified Factor IX San Dimas contains a reduced number of gamma-carboxyglutamyl residues compared to Factor IX. However, this protein undergoes metal-induced quenching of the intrinsic fluorescence. In addition, Factor IX San Dimas is unable to interact with phospholipid vesicles. The absence of coagulant activity in Factor IX San Dimas can be attributed to impaired calcium-induced conformational changes and loss in the ability to bind phospholipid vesicles in the presence of calcium ions.

description: Pheidole obtusospinosa Pergande
Pheidole obtusospinosa Pergande 1896: 889. Junior synonym of Pheidole subdentata Pergande 1896: 888, synonymy by Wheeler, 1914c: 50; subdentata Pergande is ajunior secondary homonym of Oecophthora subdentata Mayr 1853b: 145, later transferred to Pheidole and a synonym of P. pallidula (Nylander) of Eurasia; hence obtusopilosa is first available name. Syn.: Pheidole arizonica Santschi 191 ld: 3, synonymy by Creighton 1958: 211.
Types Nat. Mus. Nat. Hist. U. S.
Etymology L obtusospinosa, with blunt thorns, referring to the propodeal spines.
Diagnosis A large trimorphic species placed in the pilifera group because of the 2-toothed hypostoma of the major but with other traits conforming to the fallax group. Very close to hirtula, distinguished most readily in the supermajor, as illustrated, by the elongate foveae of the rear half of the dorsum of the head, with the interspaces densely foveolate and opaque. The tangled taxonomic history of this species and the true status of vaslitii, previously associated with it but now revealed as a junior synonym or sibling species ofhyatti (q.v.), have been presented by Ward (2000).
Measurements (mm) Supermajor: HW 2.50, HL 2.36, SL 1.12, EL 0.26, PW 1.06.
Major: HW 1.44, HL 1.46, SL 1.12, EL 0.24, PW 0.72.
Minor: HW 0.62, HL 0.80, SL 0.98, EL 0.16, PW 0.44.
Color All castes: yellowish to reddish brown.
Range Known from the mountains of southern Arizona at 300-1900 m, and from Nayarit to Nuevo Leon in Mexico.
biology Stefan Cover (unpublished field notes), who has collected obtusospinosa many times in southern Arizona, has found it consistently in woodland, variously composed of different combinations of pine, oak, and juniper. It typically nests under rocks, although Cover found one colony beneath a cow pat and another 2.5 m from the ground in the dead branch of a standing oak tree (Quercus arizonica). Creighton (1958) reports that colonies are much smaller than those of the closely related hirtula, and that in southern Arizona nuptial flights occur in early July.

description: We derive an analytical expression that describes the complete three-dimensional carrier-envelope phase (CEP) distribution of in the focal volume of ultrashort pulsed Gaussian beams focused by spherical mirrors or lenses. The focal CEP map depends on the so-called factor $g$ specifying the frequency-dependence of the beam width of the source few-cycle pulse, on its chirp and on the small chromatic aberration introduced by a lens without appreciably distorting or broadening the few-cycle pulse. We show how to tailor the CEP map of mirror-focused and lens-focused few-cycle pulses in order to produce negligible transversal and axial CEP variations in specific regions of the focal volume for phase-sensitive interactions of light with matter taking place in a volume or on a surface. We propose a quasi-achromatic doublet lens that can implement in practice these tailored CEP distributions.

description: We investigate the space-time structure of the classical gluon field produced in an ultrarelativistic collision between color charges. The classical solution which was computed previously in a perturbative approach is shown to become unstable on account of the non-Abelian self-interaction neglected in the perturbative solution scheme. The time scale for growth of the instabilities is found to be of the order of the distance between the colliding color charges. We argue that these instabilities will eventually lead to thermalization of gluons produced in an ultrarelativistic collision between heavy nuclei. The rate of thermalization is estimated to be of order $g^2 μ$, where $g$ is the strong coupling constant and $μ^2$ the transverse color charge density of an ultrarelativistic nucleus.

description: We present two new analytic formulations of the Density Matrix Renormalization Group Method. In these formulations we combine the block renormalization group (BRG) procedure with Variational and Fokker-Planck methods. The BRG method is used to reduce the lattice size while the latter are used to construct approximate target states to compute the block density matrix. We apply our DMRG methods to the Ising Model in a transverse field (ITF model) and compute several of its critical properties which are then compared with the old BRG results.

Pheidole bicarinata subsp. paiute Gregg 1959: 17. Raised to species level by G. C and J. Wheeler 1973e: 75.
Types Mus. Comp. Zool. Harvard.
Etymology Named after one of the Amerindian peoples of the southwestern United States.
diagnosis A member of the " bicarinata complex" of the larger pilifera group; for a characterization of the complex, see under bicarinata.
P. paiute is distinguished within the complex by the following combination of traits.
Major: propodeal spine in side view equilaterally triangular; humerus with a very low denticle in dorsal-oblique view; postpetiolar node laterally angular; sculpturing of head consists of carinulae confined entirely to the part anterior to the level of the posterior margin of the eyes.
Minor: some of the hairs on the promesonotal dorsum are very long; propodeal spines in side view equilaterally triangular. Measurements (mm) Paratype major: HW 1.04, HL 1.14, SL 0.54, EL 0.18, PW 0.46. Paratype minor: HW 0.50, HL 0.56, SL 0.48, EL 0.12, PW 0.30. color Major: concolorous dark yellow.
Minor: body brownish yellow, appendages brownish yellow to clear yellow.
Range Deserts of Nevada and southern California.
Biology In Nevada, George C. and Jeanette N. Wheeler (1986g) encountered paiute at 1040-2100 m in cottonwood groves, a triplex scrubland, pinyon-juniper woodland, and in disturbed habitats, nesting mostly under stones but also in open soil, where colonies built craters about 25 mm across. At Deep Canyon, near Palm Springs, California, the same authors found the species in larrea-palo verde scrub and desert, nesting in the soil; in one nest excavated, they found a cache of Oenothera clavaeformis seeds.

description: A phase-space formulation of non-stationary nonlinear dynamics including both Hamiltonian (e.g., quantum-cosmological) and dissipative (e.g., dissipative laser) systems reveals an unexpected affinity between seemly different branches of physics such as nonlinear dynamics far from equilibrium, statistical mechanics, thermodynamics, and quantum physics. One of the key insights is a clear distinction between the "vacuum" and "squeezed" states of a non-stationary system. For a dissipative system, the "squeezed state" (or the coherent "concentrate") mimics vacuum one and can be very attractable in praxis, in particular, for energy harvesting at the ultrashort time scales in a laser or "material laser" physics including quantum computing. The promising advantage of the phase-space formulation of the dissipative soliton dynamics is the possibility of direct calculation of statistical (including quantum) properties of coherent, partially-coherent, and non-coherent dissipative structure without numerically consuming statistic harvesting.

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We consider a continuous random walk model for describing normal as well as anomalous diffusion of particles subjected to an external force when these particles diffuse in a uniformly expanding (or contracting) medium. A general equation that relates the probability distribution function (pdf) of finding a particle at a given position and time to the single-step jump length and waiting time pdfs is provided. The equation takes the form of a generalized Fokker-Planck equation when the jump length pdf of the particle has a finite variance. This generalized equation becomes a fractional Fokker-Planck equation in the case of a heavy-tailed waiting time pdf. These equations allow us to study the relationship between expansion, diffusion and external force. We establish the conditions under which the dominant contribution to transport stems from the diffusive transport rather than from the drift due to the medium expansion. We find that anomalous diffusion processes under a constant external force in an expanding medium described by means of our continuous random walk model are not Galilei invariant, violate the generalized Einstein relation, and lead to propagators that are qualitatively different from the ones found in a static medium. Our results are supported by numerical simulations.

Higgs Physics at a γγCollider

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: High precision measurements of electroweak observables at $e^\pm$ colliders indicate the existence of a light Higgs boson below the $W^\pm$ threshold. If such a fundamental scalar should be found in the near future it is important to fully investigate the electroweak symmetry braking sector of the Standard Model. This is particularly important for an intermediate mass Higgs as its existence might indicate physics beyond the Standard Model, for instance in form of its minimal supersymmetric extension (MSSM). In this work we present first results on the expected precision of the partial $Γ(H \longrightarrow γγ)$ width at the $γγ$ option of a future linear collider. This quantity is sensitive to new physics as heavy particles do not decouple in general and differences between the SM and MSSM predictions can differ by up to 10% even in the decoupling limit of large pseudoscalar Higgs masses. This regime is difficult and for some values of $\tan β$ impossible to cover at the LHC. We find that the well understood background process $γγ\longrightarrow q \bar{q}$ allows for a ${\cal O} (2%)$ determination of $Γ(H \longrightarrow γγ)$ using conservative collider parameters.

Guanine nucleotide-sensitive interaction of a radiolabeled agonist with a phospholipase C-linked P

description: Analogs of ATP and ADP produce a guanine nucleotide-dependent activation of phospholipase C in turkey erythrocyte membranes with pharmacological properties consistent with those of a P2y-purinergic receptor (Boyer, J. L., Downes, C. P., and Harden, T.K. (1989) J. Biol. Chem. 264, 884-890). This study describes the interaction of adenosine-5'-O-2-thio[35S] diphosphate ([35S]ADP beta S) with this putative P2y-purinergic receptor on purified plasma membranes prepared from turkey erythrocytes. In binding assays performed at 30 degrees C, the association rate constant of [35S] was 1.1 x 10(7) M-1 min-1 and the dissociation rate constant was 3.8 x 10(-2) min-1. [35S]ADP beta S bound with high affinity (Kd = 6-10 nM) to an apparently homogeneous population of sites (Bmax = 2-4 pmol/mg protein). ATP and ADP analogs (2-methylthio ATP, ADP beta S, ATP, ADP, 5'-adenylyl imidodiphosphate, alpha, beta-methylene adenosine-5'-triphosphate, and beta, gamma-methylene adenosine 5'-triphosphate) inhibited the binding of [35S]ADP beta S with properties consistent with ligand interaction by simple law of mass action kinetics at a single site. The rank order of potency for inhibition of [35S]ADP beta S binding was identical to the potency order observed for these same agonists for stimulation of phospholipase C in turkey erythrocyte ghosts. Guanine nucleotides inhibited [35S]ADP beta S binding in a noncompetitive manner with the following potency order: guanosine 5'-O-(3-thiotriphosphate) greater than 5'-guanylyl imidodiphosphate greater than GTP = GDP greater than guanosine 5'-O-2-(thiodiphosphate). The data are consistent with the idea that [35S]ADP beta S may be used to radiolabel the P2y-purinergic receptor linked to activation of phospholipase C in turkey erythrocyte membranes. In addition, interaction of radiolabeled agonist with the receptor is modified by guanine nucleotides, providing evidence that an agonist-induced receptor/guanine nucleotide regulatory protein complex may be involved in P2y-receptor action.

Human immunodeficiency virus reverse transcriptase-associated RNase H activity

name: CHENG, Y
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1989

description: Biochemical characteristics of the RNase H activity associated with immunoaffinity purified human immunodeficiency virus (HIV) reverse transcriptase (RT) were examined. Glycerol gradient centrifugation of HIV RT resulted in a single peak of RNase H, associated with RT activity, with an apparent molecular weight of 110,000. HIV RNase H exhibited a marked substrate preference for poly(dC).[3H]poly(rG) compared to poly(dT).[3H]poly(rA). It did not hydrolyze single-stranded RNA or the DNA component of DNA.RNA hybrids. Products of the HIV RT-associated RNase H reaction consisted primarily of monomers, dimers, and trimers with 3' OH groups. This reaction was Mg2+ dependent, with greater than 90% of maximum activity at MgCl2 concentrations between 4 and 12 mM. The optimum KCl concentration for HIV RT catalyzed polymerization with a poly(rA).(dT)10 template. The optimum pH for HIV RNase H activity was between 8.0 and 8.5, in contrast to an optimum pH of 7.5 to 8.0 for HIV RT activity. The association of RNase H activity with the p66 component of HIV RT was demonstrated by activity gel analysis. These results indicate that HIV RT has an integral RNase H activity; however, some of its properties are different from those of RNase H associated with other retroviral RT's, and optimal assay conditions are different than those for HIV RT catalyzed DNA polymerization.

By using quark-lepton symmetries, derived from Grand Unification and/or string theories, we show how to determine the necessary neutrino parameters. In addition, the seesaw neutrino masses set the scale for the proton decay operators by ``measuring'' the standard model cut-off. The SuperKamiokande values suggest that proton decay is likely to be observed early in the XXIst Century.

Increased incidence of CAD gene amplification in tumorigenic rat lines as an indicator of genomic instability of neoplastic cells
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1989

description: It has been hypothesized that genomic instability is an important component of tumorigenesis. In an attempt to establish this relationship, we determined the frequencies with which two nontumorigenic and four tumorigenic rat liver epithelial cell lines underwent a particular type of genetic instability, gene amplification. By exposing cells to N-(phosphonoacetyl)-L-aspartate (PALA), a drug which specifically inhibits the aspartate transcarbamylase activity of the multifunctional CAD enzyme and selects for amplification of the CAD gene, we observed a striking parallel between the ability of these cell lines to become resistant to this drug and the ability of these same cells to form tumors after injection into day-old syngeneic rats. Cells of one highly tumorigenic line became resistant to PALA greater than 70 times more often than those of a non-tumorigenic line. Molecular analyses of eight independent PALA-resistant subclones confirmed that, in each case, this resistance was due to amplification of the CAD gene. Thus, our results demonstrate the relationship between tumorigenicity and at least one measure of genomic instability, CAD gene amplification. The method developed in this study provides a quantitative, rapid indicator of tumorigenicity and should prove useful in trying to elucidate the underlying basis of genomic instability in neoplastic cells.

We present two possible approaches for a realistic study of the reaction and discuss the differences between them. We find that the optimal method to study double Z resonant production and to quantify the presence of anomalous couplings requires the use of a complete four-fermion final-state calculation.

description: We study chimera states, which are partial synchronization patterns consisting of spatially coexisting domains of coherent (synchronized) and incoherent (desynchronized) dynamics, in ring networks of FitzHugh-Nagumo oscillators with fractal connectivities. In particular, we focus on the interplay of time delay in the coupling term and the network topology. In the parameter plane of coupling strength and delay time we find tongue-like regions of existence of chimera states alternating with regions of coherent dynamics. We show analytically and numerically that the period of the synchronized dynamics as a function of delay is characterized by a sequence of piecewise linear branches. In between these branches various chimera states and other partial synchronization patterns are induced by the time delay. By varying the time delay one can deliberately choose and stabilize desired spatio-temporal patterns.

Impacts and perspectives of woodland creation in upland Cumbria, UK
Creators: name: Iversen, Sara Vangerschov
Publisher: name: Lancaster University
Year: 2019

description: Upland regions in the UK are increasingly under consideration as potential areas for the creation of woodlands. This is driven by a combination of factors, including the aims of UK forestry policy to increase woodland cover, changes in current upland land-use and management, agro-environment schemes in national and international policy and an increasing public awareness of the ecosystem service benefits landscapes can deliver for society. Creating new woodlands in upland areas is challenging, partly due to concerns of the potential impacts from a change in land use and also due to stakeholder perspectives. This research carries out a rapid TESSA ecosystem services assessment of a 250km2 grass dominated and sheep grazed Cumbrian (England) upland landscape and applies plausible alternative woodland creation scenarios of woodland cover percentages. The assessment focusses on changes these scenarios will deliver in terms of key ecosystem goods and services, which are identified by stakeholders to be of high importance to the study area. The results indicate that, under lower woodland percentage scenarios, no drawbacks and only benefits on all indicators are expected. However, a more complex outcome would be expected from the higher percentage woodland scenarios. The research furthermore adds a qualitative element to the overall understanding, by carrying out a Q-methodology investigation of stakeholder perspectives of upland woodland creation. The findings suggest that stakeholder perspectives are a powerful influence in upland woodland creation. The two components of research methods applied to the study complement each other and offer a greater understanding of this complex topic and identify barriers and opportunities for woodland creation in the uplands of Cumbria.

description: The dynamics of micro-resonators (or any mechanical resonators) can be studied by two complementary methods allowing the measurements in two different domains: (i) in the frequency domain - by the frequency sweeps using cw-excitation, and (ii) in the time domain - by the pulse techniques, when the free-decay oscillations are investigated. To broaden the knowledge about the intrinsic mechanical properties of micro-resonators based on a Sn-whisker we used both methods. We show that the dynamics of the Sn-whisker can be described by a phenomenological theory of the Duffing oscillator. Furthermore, we present the results of theoretical analysis based on the Duffing's model provided in the time and frequency domains, and we show that these results are qualitatively the same with those measured experimentally.

description: We have derived long series expansions of the percolation probability for site, bond and site-bond percolation on the directed triangular lattice. For the bond problem we have extended the series from order 12 to 51 and for the site problem from order 12 to 35. For the site-bond problem, which has not been studied before, we have derived the series to order 32. Our estimates of the critical exponent $β$ are in full agreement with results for similar problems on the square lattice, confirming expectations of universality. For the critical probability and exponent we find in the site case: $q_c = 0.4043528 \pm 0.0000010$ and $β= 0.27645 \pm 0.00010$; in the bond case: $q_c = 0.52198\pm 0.00001$ and $β= 0.2769\pm 0.0010$; and in the site-bond case: $q_c = 0.264173 \pm 0.000003$ and $β= 0.2766 \pm 0.0003$. In addition we have obtained accurate estimates for the critical amplitudes. In all cases we find that the leading correction to scaling term is analytic, i.e., the confluent exponent $Δ= 1$.

description: Based on a $2\times 2$ mass matrix, the mixing angle of the axial vector states $f_1(1420)$ and $f_1(1285)$ is determined to be $51.5^{\circ}$, and the theoretical results about the decay and production of the two states are presented. The theoretical results are in good agreement with the present experimental results, which suggests that $f_1(1420)$ can be assigned as the partner of $f_1(1285)$ in the $^3P_1$ $q\bar{q}$ nonet. We also suggest that the existence of $f_1(1510)$ needs further experimental confirmation.

description: The insulin-like growth factors (IGFs) I and II exert pleiotropic effects on diverse cell types through interaction with specific high affinity cell surface receptors and with locally produced binding proteins. In skeletal muscle and in myoblast cell lines, the functions of IGF-I and -II are complex. Both growth factors appear capable of stimulating cellular proliferation and differentiation, as well as exerting insulin-like effects on intermediary metabolism. We have demonstrated recently that the expression of IGF-II and its receptor is induced during the terminal differentiation of the myoblast cell line, C2, and have suggested that IGF-II may be an autocrine growth factor in these cells (Tollefsen, S.E., Sadow, J.L., and Rotwein, P. (1989) Proc. Natl. Acad. Sci. U.S.A. 86, 1543-1547). We now have examined this cell line for expression of other components involved in IGF signaling. The synthesis of IGF-I is low during myoblast proliferation; IGF-I mRNA can be detected only through use of a sensitive solution hybridization assay. Typical IGF-I receptors can be measured in myoblasts, whereas IGF binding proteins cannot be detected in proliferating cells or in conditioned culture medium. During myogenic differentiation, IGF-I mRNA levels increase transiently by 6-10-fold within 48-72 h. The expression of IGF-I mRNA is accompanied by a 2.5-fold accumulation of IGF-I in the culture medium. IGF-I receptors also increase transiently, doubling by 48 h after the onset of differentiation. By contrast, secretion of a Mr 29,000 IGF binding protein is induced 30-fold to 100 ng/ml within 16 h and continues to increase throughout differentiation. These studies demonstrate that several components critical to IGF action are produced in a fusing skeletal muscle cell line in a differentiation-dependent manner and suggest that both IGF-I and IGF-II may be autocrine factors for muscle.

description: The atmospheric neutrino oscillations and the vacuum oscillation solution of the solar neutrino problem can be consistently described by a doubly or triply degenerate neutrino spectrum as long as the high level of degeneracy required is not spoiled by radiative corrections. We show that this is the case for neutrino mass matrices generated by symmetries. This imposes a strong constraint on the mixing angles and requires the mixing should be close to bi-maximal. We briefly discuss the relevance of our results for the measurability of the neutrino spectrum.

description: Im Epidemiologischen Bulletin 42/2019 berichtet das NRZ für Staphylokokken und Enterokokken über Häufigkeit, Eigenschaften und Verbreitung von MRSA in Deutschland. Trotz rückläufiger MRSA-Prävalenzen und -Inzidenzen ergibt sich im Vergleich mit den Vorjahren eine unverändert hohe Anzahl an Staphlococcus aureus-/MRSA-Einsendungen an das NRZ. Die detaillierte Analyse von Erregern, insbesondere die Erstellung eines sogenannten mikrobiellen genetischen Fingerabdrucks, ist unverzichtbar, um Ausbruchsgeschehen zu erkennen und evolutionäre Entwicklungen darzustellen. Bestimmte Ko-Resistenzen (Fluorchinolone, Makrolide) sind bei MRSA weiterhin rückläufig. Alleinig die Resistenzentwicklung gegenüber Tetracyclin zeigte einen leicht ansteigenden Trend.

description: This paper focuses on the derivation of the distribution of diffused particles absorbed by an agent in a bounded environment. In particular, we analogously consider to derive the impulse response of a molecular communication channel in 2-D and 3-D environment. In 2-D, the channel involves a point transmitter that releases molecules to a circular absorbing receiver that absorbs incoming molecules in an environment surrounded by a circular reflecting boundary. Considering this setup, the joint distribution of the molecules on the circular absorbing receiver with respect to time and angle is derived. Using this distribution, the channel characteristics are examined. Furthermore, we also extend this channel model to 3-D using a cylindrical receiver and investigate the channel properties. We also propose how to obtain an analytical solution for the unbounded 2-D channel from our derived solutions, as no analytical derivation for this channel is present in the literature.

Chaos modified wall formula damping of the surface motion of a cavity undergoing fissionlike shape evolutions

description: The chaos weighted wall formula developed earlier for systems with partially chaotic single particle motion is applied to large amplitude collective motions similar to those in nuclear fission. Considering an ideal gas in a cavity undergoing fission-like shape evolutions, the irreversible energy transfer to the gas is dynamically calculated and compared with the prediction of the chaos weighted wall formula. We conclude that the chaos weighted wall formula provides a fairly accurate description of one body dissipation in dynamical systems similar to fissioning nuclei. We also find a qualitative similarity between the phenomenological friction in nuclear fission and the chaos weighted wall formula. This provides further evidence for one body nature of the dissipative force acting in a fissioning nucleus.

Kinetics and activation of phospholipase C by P2Y purinergic agonists and guanine nucleotides

Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Membranes prepared from [3H]inositol-labeled turkey erythrocytes express a phospholipase C that is markedly stimulated by stable analogs of GTP (Harden, T. K., Stephens, L., Hawkins, P. T., and Downes, C. P. (1987) J. Biol. Chem. 262, 9057-9061). We now report that P2-purinergic receptor-mediated regulation of the enzyme occurs in the membrane preparation. The order of potency of a series of ATP and ADP analogs for stimulation of inositol phosphate formation, i.e. 2-methylthioadenosine 5'-triphosphate (2MeSATP) greater than adenosine 5'-O-(2-thiodiphosphate) greater than adenosine 5'-O-(3-thiotriphosphate) greater than ATP greater than 5'-adenylyl imidodiphosphate approximately ADP greater than alpha, beta-methyleneadenosine 5'-triphosphate greater than beta, gamma-methyleneadenosine 5'-triphosphate, was consistent with that for the P2Y-purinergic receptor subtype. Agonist-stimulated effects were completely dependent on the presence of guanine nucleotide. Activation of phospholipase C by guanosine 5'-O-(3-thiotriphosphate) (GTP gamma S) occurred with a considerable time lag. The rate of activation followed first order kinetics and was markedly increased by increasing concentrations of a P2Y receptor agonist; in contrast, the rate of activation at a fixed agonist concentration was independent of guanine nucleotide concentration. Addition of guanosine 5'-O-(2-thiodiphosphate) (GDP beta S) prior to addition of agonist and GTP, 5'-guanylyl imidodiphosphate (Gpp(NH)p), or GTP gamma S blocked in a concentration-dependent manner the stimulatory effect of guanine nucleotide. GDP beta S, added subsequent to preactivation of membranes with 2MeSATP and GTP gamma S or Gpp(NH)p had only small inhibitory effects on the rate of inositol phosphate production observed over the subsequent 10 min. In contrast, addition of GDP beta S to GTP-preactivated membranes resulted in a rapid return of enzyme activity to the basal state within 60 s. Taken together, the data are consistent with the idea that P2Y receptor activation increases the rate of exchange of GTP and GTP analogs for GDP on the relevant guanine nucleotide regulatory protein. Once the active enzymic species is formed, hydrolysis of guanine nucleotide reverts the enzyme to the inactive state.

description: The aim of our study is to investigate the physical properties of the star-forming interstellar medium (ISM) in the Large Magellanic Cloud (LMC) by separating the origin of the emission lines spatially and spectrally. Following Okada et al. (2015, Paper I), we investigate different phases of the ISM traced by carbon-bearing species in four star-forming regions in the LMC, and model the physical properties using the KOSMA-tau PDR model. We mapped 3--13 arcmin$^2$ areas in 30 Dor, N158, N160 and N159 along the molecular ridge of the LMC in [CII]158um with GREAT on board SOFIA, and in CO(2-1) to (6-5), $^{13}$CO(2-1) and (3-2), [CI]3P1-3P0 and 3P2-3P1 with APEX. In all four star-forming regions, the line profiles of CO, $^{13}$CO, and [CI] emission are similar, whereas [CII] typically shows wider line profiles or an additional velocity component. For selected positions in N159 and 30 Dor, we observed the velocity-resolved [OI] 145um and 63um lines for the first time with upGREAT. At some positions, the [OI] line profiles match those of CO, at other positions they are more similar to the [CII] profiles. We interpret the different line profiles of CO, [CII] and [OI] as contributions from spatially separated clouds and/or clouds in different physical phases, which give different line ratios depending on their physical properties. We model the emission from the CO, [CI], [CII], and [OI] lines and the far-infrared continuum emission using the latest KOSMA-tau PDR model, which treats the dust-related physics consistently and computes the dust continuum SED together with the line emission of the chemical species. We find that the line and continuum emissions are not well-reproduced by a single clump ensemble. Toward the CO peak at N159~W, we propose a scenario that the CO, [CII], and [OI] 63um emission are weaker than expected because of mutual shielding among clumps. (abridged for arXiv)
