Ryanodine activation and inhibition of the Ca2+ release channel of sarcoplasmic reticulum.
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: 1986

description: The effect of the plant alkaloid ryanodine on the skeletal muscle sarcoplasmic reticulum Ca2+ release channel was studied by determining the Ca2+ permeability of "heavy" vesicles passively loaded with 45Ca2+ in the presence or absence of ryanodine. Depending on the experimental conditions, ryanodine either stimulated or inhibited Ca2+ efflux. Vesicles were rendered permeable to 45Ca2+ at a ryanodine concentration of 0.01 microM when diluted into a medium containing the two Ca2+ release channel inhibitors Mg2+ and ruthenium red. At ryanodine concentrations greater than 10 microM, 45Ca2+ efflux was inhibited in channel-activating (5 microM Ca2+) or -inhibiting (10 mM Mg2+ plus 10 microM ruthenium red) media. An optimal stimulatory effect was observed when vesicles were incubated with ryanodine at 37 degrees C and in media that caused partial opening of the channel. Similar results to those described above were obtained using cardiac sarcoplasmic reticulum vesicles that were capable of rapid 45Ca2+ efflux. Use of the slowly permeating molecule L-[3H]glucose allowed measurement of channel-mediated efflux rates from vesicles in the presence and absence of ryanodine. At low activating concentrations, ryanodine did not appreciably change the regulation of L-glucose efflux rates by external Ca2+, Mg2+, and adenine nucleotide. These results suggested two possible modes of action of ryanodine: 1) a change in the gating mechanism of the channel which is not readily detected using the slowly permeating molecule L-glucose or 2) a change in channel structure which prevents its complete closing.

description: Clostridioides difficile has significant clinical importance as a leading cause of healthcare-associated infections, with symptoms ranging from mild diarrhoea to severe colitis, and possible life-threatening complications. C. difficile ribotype (RT) 002, mainly associated with MLST sequence type (ST) 8, is one of the most common RTs found in humans. This study aimed at investigating the genetic characteristics of 537 C. difficile genomes of ST8/RT002. To this end, we sequenced 298 C. difficile strains representing a new European genome collection, with strains from Germany, Denmark, France and Portugal. These sequences were analysed against a global dataset consisting of 1,437 ST8 genomes available through Enterobase. Our results showed close genetic relatedness among the studied ST8 genomes, a diverse array of antimicrobial resistance (AMR) genes and the presence of multiple mobile elements. Notably, the pangenome analysis revealed an open genomic structure. ST8 shows relatively low overall variation. Thus, clonal isolates were found across different One Health sectors (humans, animals, environment and food), time periods, and geographical locations, suggesting the lineage’s stability and a universal environmental source. Importantly, this stability did not hinder the acquisition of AMR genes, emphasizing the adaptability of this bacterium to different selective pressures. Although only 2.4 % (41/1,735) of the studied genomes originated from non-human sources, such as animals, food, or the environment, we identified 9 cross-sectoral core genome multilocus sequence typing (cgMLST) clusters. Our study highlights the importance of ST8 as a prominent lineage of C. difficile with critical implications in the context of One Health. In addition, these findings strongly support the need for continued surveillance and investigation of non-human samples to gain a more comprehensive understanding of the epidemiology of C. difficile.

description: Coarse-grained Langevin-type effective field equations are derived for classical systems of particles. These equations include the effects of thermal fluctuation and dissipation which may arise from coupling to an external bath, as in the Brownian motion of a single particle, or which may arise from statistical fluctuations in small parts of an isolated many-particle system, as in sound waves. These equations may provide some guidance for the analysis of mesoscopic or microscopic molecular systems, or for systems of hundreds to thousands of subatomic particles produced in high energy nuclear collisions.

description: In this paper we investigate the issue of representation within the Journal of Mathematics Teacher Education (JMTE) and the broader academic publishing landscape, particularly focusing on the underrepresentation of authors from various world regions. A questionnaire, distributed globally, aimed to amplify the voices of the underrepresented, exploring the constraints and affordances of publishing in English-medium mathematics education research journals. The question that guided our investigation was: What do voices from the mathematics education community raise in their responses to questions about publishing in English-medium research journals like JMTE? We used qualitative methods to review the responses and identify common themes. The findings revealed significant barriers and challenges related to language, research location, and institutional support, highlighting the complexities of navigating the global academic community and the academic publishing culture. We propose actionable suggestions to foster a more equitable, diverse, and inclusive publishing environment.

description: We have determined the nucleotide sequence of the uvrA gene of Escherichia coli. The coding region of the gene is 2820 base pairs which specifies a protein of 940 amino acids and Mr = 103,874. The polypeptide sequence predicted from the DNA sequence was confirmed by analyzing the UvrA protein: the sequence of the first 7 NH2-terminal amino acids as well as the amino acid composition of the pure protein agreed with those predicted from the nucleotide sequence. By comparing the sequence of UvrA protein to the amino acid sequences of other ATPases, we found that two regions in the UvrA protein, separated from one another by about 600 amino acids, have the highly conserved G-X4-GKT(S)-X6-I(V) sequence found at the active sites of many, but not all, ATPases. Our findings suggest that UvrA protein may have two ATP binding sites.

description: We have measured the transverse ultrasonic attenuation, $α_{qε}$, in a well-characterized single crystal of $UPt_3$ for propagation direction, ${\bf q}$, in the basal plane and polarization, $ε$, in and out of the plane. Unlike previous measurements, the sample was of sufficient purity to exhibit three well-defined phases as a function of temperature and magnetic field. We uncover a functional dependence for the attenuation in the (zero field) high temperature phase (A-phase) which is distinctly different than that in the low temperature (B) phase. Our data provide unique directional information on the quasiparticle momentum distribution in this largely unstudied phase of $UPt_3$ and provide the first direct evidence that the two zero-field phases possess different symmetries.

description: An unbiased search of molecular outflows within the region of the COHRS survey has identified 157 high-mass outflows from a sample of 770 ATLASGAL clumps with a detection rate of 20\%. The detection rate of outflows increases for clumps with higher M$_{clump}$, L$_{bol}$, L$_{bol}$/M$_{clump}$, N$_{H_{2}}$, and T$_{dust}$ compared to the clumps with no outflow. The detection rates of the outflow increases from protostellar (8\%) to YSO clump (17\%) and to MSF clump (29\%). The detection rate 26\% for quiescent clump is preliminary, because the sample of quiescent clumps is small. A statistical relation between the outflow and clump masses for our sample is $\log(M_{out}/M_{\bigodot}) = (-1.1\pm0.21) + (0.9\pm0.07)\log(M_{clump}/M_{\bigodot})$. The detection rate of outflows and the outflow mass-loss rate show an increase with increasing M$_{clump}$, L$_{bol}$, N$_{H_{2}}$, and T$_{dust}$, which indicates that clumps with outflow with higher parameter values are at a more advanced evolutionary stage. The outflow mechanical force increases with increasing bolometric luminosities. No clear evidence has yet been found that higher mass outflows have different launching conditions than low-mass outflows.

description: The paper deals with the modelling and control of a double winded induction generator. The controlled process is an induction generator with distinct excitation winding. At the generator terminal is connected a load (electrical consumer). There are presented the results obtained by using a minimum variance adaptive control system. The main goal of the control structure is to keep the generator output (terminal voltage) constant by controlling the excitation voltage from the distinct winding. The study cases in the paper are for the validation of the reduced order model of induction generator (5th order model) used only to design the adaptive controller. There is also validated the control structure. There were considered variations of the mechanical torque.

Pheidole clementensis Gregg 1969b: 93.
Types Natural History Museum of Los Angeles County; Mus. Comp. Zool. Harvard; Amer. Mus. Nat. Hist.
Etymology Referring to the type locality.
Diagnosis A member of the " pilifera complex" of the larger pilifera group; for a characterization of the complex, see under pilifera. P. clementensis is distinguished within the complex by the following combination of traits.
Major: side of head densely rugoreticulate; occiput extensively rugulose; pronotum smooth and shiny, propodeal spine moderately large, acute; postpetiole from above trapezoidal; humerus in dorsal-oblique view low and smooth and shiny.
Closest to californica, from which it differs by its larger size (HW in clementensis about 1.1 mm, in californica major about 0.90 mm) and proportionately smaller eye (major EL/HW 0.13 in clementensis versus 0.20 in californica). Measurements (mm) Paratype major: HW 1.08, HL 1.18, SL 0.54, EL 0.14, PW 0.54. Paratype minor: HW 0.54, HL 0.56, SL 0.52, EL 0.12, PW 0.30.
Color Major: head dark yellow, with at least occasionally a pair of medium brown spots on vertex, falling on either side of the cephalic midline; rest of body light yellowish brown. Minor: body concolorous dark brown, appendages yellow.
Range San Clemente Island and parts of mainland California (Philip S. Ward, personal communication).
biology Roy Snelling (in Gregg 1969b) reports that P. clementensis is one of the commonest ants on San Clemente Island (especially on the seaward side), where it nests under stones. The minor workers are nocturnal, starting to forage shortly before sundown. They are evidently mostly or entirely granivorous, preferring the seeds of Cassus cretica but also gathering grass seeds and those of a small legume, probably a species of Lotus. The majors form an unusually high percentage of the worker population.

The formation of a novel free radical metabolite from CCl4 in the perfused rat liver and in vivo.

description: Electron spin resonance spectroscopy has been used to monitor free radicals formed during CCl4 metabolism by perfused livers from phenobarbital-treated rats. Livers were perfused simultaneously with the spin trap phenyl N-t-butylnitrone and with either 12CCl4 or 13CCl4. Perfusate samples and CHCl3:CH3OH extracts of perfusate and liver samples were analyzed for phenyl N-t-butylnitrone radical adducts of reactive free radicals. In the organic extracts, hyperfine coupling constants and 13C isotope effects observed in the ESR spectra indicated the presence of the radical adduct of the trichloromethyl radical. Surprisingly, an additional free radical signal about two orders of magnitude more intense than that of the phenyl N-t-butylnitrone/CCl.3 radical adduct was observed in the aqueous liver perfusate. This adduct was also detected by ESR in rat urine 2 h after intragastric addition of spin trap and CCl4. This radical adduct had hyperfine coupling constants and 13C isotope effects identical with the radical adduct of the carbon dioxide anion radical (CO2-.). Analysis of the pH dependence of the coupling constants yielded a pK alpha of 2.8 for the CO2-. radical adduct formed either in the perfused liver or chemically. Carbon tetrachloride is converted into CCl.3 by cytochrome P-450 through a reductive dehalogenation. The trichloromethyl free radical reacts with oxygen to form the trichloromethyl peroxyl radical, CCl3OO., which may be converted into .COCl and then trapped. This radical adduct would hydrolyze to the carboxylic acid form, which is detected spectroscopically. Alternatively, the carbon dioxide anion free radical could form through complete dechlorination and then react with the spin trap to give the CO2-. radical adduct directly.

An independent and complete set of variables for the colourless sector is determined. A general scheme to construct the eigenstates of the electric energy operator using a symbolic method is described. It is shown how the one-plaquette problem can be mapped onto a N-fermion problem. Explicit solutions for U(1), SU(2), SU(3), SU(4), and SU(5) lattice gauge theory are shown.

description: A new class of exact supersymmetric solutions is derived within minimal $d = 6$ $F(4)$ gauged supergravity. These flows are all characterized by a non-trivial radial profile for the 2-form gauge potential included into the supergravity multiplet. In particular three solutions within this class are featured by an $\mathrm{AdS}_3$ foliation of the 6d background and by an $\mathrm{AdS}_6$ asymptotic geometry. Secondly, considering the simplest example of these, we give its massive IIA uplift describing a warped solution of the type $\mathrm{AdS}_3\times S^2\times S^3$ fibered over two intervals $I_r \times I_ξ$ . We interpret this background as the near-horizon of a D4 $-$ D8 system on which a bound state D2 $-$ NS5 $-$ D6 ends producing a surface defect. Finally we discuss its holographic dual interpretation in terms of a $\mathcal{N} = (0, 4)$ SCFT$_2$ defect theory within the $\mathcal{N} = 2$ SCFT$_5$ dual to the $\mathrm{AdS}_6\times S^4$ massive IIA warped vacuum.

description: We present a design for a superconducting, on-chip circulator composed of dynamically modulated transfer switches and delays. Design goals are set for the multiplexed readout of superconducting qubits. Simulations of the device show that it allows for low-loss circulation (insertion loss < 0.35 dB and isolation >20 dB) over an instantaneous bandwidth of 2.3 GHz. As the device is estimated to be linear for input powers up to -65 dBm, this design improves on the bandwidth and power-handling of previous superconducting circulators by over a factor of 50, making it ideal for integration with broadband quantum limited amplifiers.

description: A new feature selection method based on kernelized fuzzy rough sets (KFRS) and the memetic algorithm (MA) is proposed for transient stability assessment of power systems. Considering the possible real-time information provided by wide-area measurement systems, a group of system-level classification features are extracted from the power system operation parameters to build the original feature set. By defining a KFRS-based generalized classification function as the separability criterion, the memetic algorithm based on binary differential evolution (BDE) and Tabu search (TS) is employed to obtain the optimal feature subsets with the maximized classification capability. The proposed method may avoid the information loss caused by the feature discretization process of the rough-set based attribute selection, and comprehensively utilize the advantages of BDE and TS to improve the solution quality and search efficiency. The effectiveness of the proposed method is validated by the application results on the New England 39-bus power system and the southern power system of Hebei province.

diagnosis A member of the " pilifera complex" of the larger pilifera group; for a characterization of the complex, see under pilifera. P. creightoni is distinguished within the complex by the following combination of traits.
Major: occiput in side view very broad, as much as 1.5X the anterior cephalic capsule border; promesonotum forms a smooth, single convexity; petiolar node tapering to a blunt point in side view and with a deeply concave border seen from behind; postpetiole from above spinose.
Minor: yellowish brown; eye very large; humerus subangulate in dorsal-oblique view; petiolar node tapers to a blunt point in side view; postpetiole seen from above trapezoidal.
Measurements (mm) Paratype major: HW 1.22, HL 1.32, SL 0.58, EL 0.16, PW 0.48. Paratype minor: HW 0.54, HL 0.60, SL 0.52, EL 0.14, PW 0.32.
Color Major: most of body and head, as well as mandibles, light reddish yellow; gaster plain light brown; legs clear dark yellow. Minor: body light yellowish brown, appendages clear dark yellow.
Range Northern California to Oregon and Nevada.
Biology William S. Creighton (in Gregg 1955a) found 18 earthen nests of creightoni at the type locality, frequently near nests of the much larger ant Messor (= Veromessor) andrei. The entrances were surrounded by large rings of chaff, indicating that seeds are an important part of the diet. Tissue of freshly killed ground squirrels was also accepted by the majors and minors, which foraged in fdes. Soil nests have also been recorded on museum labels, in California by Diane W. Davidson and in Nevada by Philip S. Ward. Nuptial flights were recorded in August and September by Davidson and by Creighton respectively; they occurred about an hour before sunset.

Treatment of prelabeled C62B cells with 1 mM acetylcholine (ACh) resulted in an accumulation of radioactive phosphatidate irrespective of which fatty acid was used as a label. However, only in cells prelabeled with unsaturated fatty acids were increases in radioactive fatty acids observed. When exogenous radioactive arachidonate was added to C62B cells in the presence of 1 mM ACh, there was a rapid, selective, and transiently enhanced incorporation of label (several times the control) into phosphatidylinositol (PI). The ACh-enhanced incorporation into PI was not preceded by enhanced incorporation of label into sn-1,2-diacylglycerol or phosphatidate but was followed by an increased labeling of polyphosphoinositides. Similarly, incorporation of oleate into PI was enhanced by ACh. In contrast, ACh did not enhance the incorporation of label into any glycerolipids when saturated fatty acids were used. C62B cells, incubated with [2-3H]inositol for 18 h selectively incorporated label into phosphoinositides. Stimulation of [2-3H]inositol-labeled cells with 1 mM ACh in the presence of 25 mM LiCl resulted in a rapid accumulation of radioactive inositol phosphates (mono-, bis-, and trisphosphates) and glycerophosphoinositol. The accumulation of inositol trisphosphates preceded that of inositol monophosphate and glycerophosphoinositol, while the accumulation of glycerophosphoinositol paralleled the time required for the ACh-stimulated esterification of arachidonate. These results suggest that ACh stimulates activation of a phospholipase C in C62B cells and release of 1,4,5-inositol trisphosphate. There is subsequent activation of phospholipase A2, which in turn liberates arachidonate from PI. The resulting lyso PI is either rapidly reesterified with unsaturated fatty acid to resynthesize PI, or further deacylated to yield glycerophosphoinositol.

description: We have numerically investigated the 1/5-depleted Heisenberg square lattice representing CaV4O9 using the Quantum Monte Carlo loop algorithm. We have determined the phase diagram of the model as a function of the ratio of the two different couplings: bonds within a plaquette and dimer bonds between plaquettes. By calculating both the spin gap and the staggered magnetization we determine the range of stability of the long range ordered (LRO) phase. At isotropic coupling LRO survives the depletion. But the close vicinity of the isotropic point to the spin gap phase leads us to the conclusion that already a small frustrating next nearest neighbor interaction can drive the system into the quantum disordered phase and thus explain the spin gap behavior of CaV4O9.

description: We prove that the atom spectrum, which is a topological space associated to an arbitrary abelian category introduced by Kanda, of the category of finitely presented graded modules over a graded ring $R$ is given as a union of the homogeneous spectrum of $R$ with some additional points, which we call non-standard points. This description of the atom spectrum helps in understanding the sheafification process in toric geometry: if $S$ is the Cox ring of a normal toric variety $X$ without torus factors, then a finitely presented graded $S$-module sheafifies to zero if and only if its atom support consists only of points in the atom spectrum of $S$ which either lie in the vanishing locus of the irrelevant ideal of $X$ or are non-standard.

description: Escherichia coli DNA photolyase (photoreactivating enzyme) is a flavoprotein. The enzyme binds to DNA containing pyrimidine dimers in a light-independent step and, upon illumination with 300-600 nm radiation, catalyzes the photosensitized cleavage of the cyclobutane ring thus restoring the integrity of the DNA. We have studied the binding reaction using the techniques of nitrocellulose filter binding and flash photolysis. The enzyme binds to dimer-containing DNA with an association rate constant k1 estimated by two different methods to be 1.4 X 10(6) to 4.2 X 10(6) M-1 S-1. The dissociation of the enzyme from dimer-containing DNA displays biphasic kinetics; for the rapidly dissociating class of complexes k2 = 2-3 X 10(-2) S-1, while for the more slowly dissociating class k2 = 1.3 X 10(-3) to 6 X 10(-4) S-1. The equilibrium association constant KA, as determined by the nitrocellulose filter binding assay and the flash photolysis assay, was 4.7 X 10(7) to 6 X 10(7) M-1, in reasonable agreement with the values predicted from k1 and k2. From the dependence of the association constant on ionic strength we conclude that the enzyme contacts no more than two phosphodiester bonds upon binding; this strongly suggests that the pyrimidine dimer is the main structural determinant of specific photolyase-DNA interaction and that nonspecific ionic interactions do not contribute significantly to substrate binding.

description: Recently, graphene is of highly interest owing to its outstanding conductivity, mechanical strength, thermal stability, etc. Among various graphene synthesis methods, atmosphere pressure chemical vapor deposition (APCVD) is one of the best synthesis one due to very low diffusitivity coefficient and a critical step for graphene-based device fabrication. High-temperature APCVD processes for thin film productions are being recognized in many diversity technologies such as solid-state electronic devices, in particular, high quality epitaxial semiconductor films for silicon bipolar and metal oxide semiconductor (MOS) transistors. Graphene-based devices exhibit high potential for applications in flexible electronics, optoelectronics, and energy harvesting. In this chapter, recent advances of APCVD-based graphene synthesis and their related applications will be addressed.

description: We consider constraints on the isoscalar S-wave pi-N scattering length a+ from pi-deuteron scattering, to third order in small momenta and pion masses in chiral perturbation theory. To this order, the pi-deuteron scattering length is determined by a+ together with three-body corrections that involve no undetermined parameters. We extract a novel value for a combination of dimension two low-energy constants which is in agreement with previous determinations.

Types Mus. Comp. Zool. Harvard.
Etymology Eponymous.
Diagnosis A small brown member of the pilifera group distinguished by the following traits.
Major: mesonotal convexity small, obtuse-subangular; metanotal groove absent, with metanotal profile forming a continuous line with that of the basal propodeal face; mesonotal dorsum, mesopleuron, and side of propodeum covered with longitudinal carinulae, foveolate, and opaque; pronotal dorsum transversely and pronotal sides longitudinally carinulate, foveolate, and opaque.
Minor: mesopleuron and side of propodeum longitudinally carinulate; all of mesosoma foveolate and opaque.
Close to adrianoi of Florida but differing in the above and other characters.
Measurements (mm) Paratype major: HW 0.98, HL 0.96, SL 0.44, EL 0.12, PW 0.46.
Paratype minor: HW 0.44, HL 0.46, SL 0.42, EL 0.08, PW 0.30.
Color Major: body light reddish to yellowish brown.
Minor: body concolorous dark reddish brown; antennae yellowish brown.
Range In the United States, davisi has been recorded from New York to North Carolina and northern Alabama. I have also identified a series collected by Stuart and Jarmila Kukalova-Peck from the Mesa de Chipinque Monterrey, Nuevo Leon, in northeastern Mexico. The species thus appears to have a disjunct distribution between the southeastern U.S. and northeastern Mexico, of the kind known in many other animal and plant species.
Biology In the eastern United States, davisi is typically an inhabitant of pine barrens, where it has been found in crater nests constructed in open sandy areas exposed to the sun. Its habitat in Mexico is unknown. Colonies have been observed to harvest seeds (Stefan Cover).

Reconciling the Two-Loop Diagrammatic and Effective Field Theory Computations of the Mass of the Lightest CP-even Higgs Boson in the MSSM

description: The mass of the lightest CP-even Higgs boson of the minimal supersymmetric extension of the Standard Model (MSSM) has previously been computed including O(alpha alpha_s) two-loop contributions by an on-shell diagrammatic method, while approximate analytic results have also been obtained via renormalization-group-improved effective potential and effective field theory techniques. Initial comparisons of the corresponding two-loop results revealed an apparent discrepancy between terms that depend logarithmically on the supersymmetry-breaking scale, and different dependences of the non-logarithmic terms on the squark mixing parameter, X_t. In this paper, we determine the origin of these differences as a consequence of different renormalization schemes in which both calculations are performed. By re-expressing the on-shell result in terms of MS-bar parameters, the logarithmic two-loop contributions obtained by the different approaches are shown to coincide. The remaining difference, arising from genuine non-logarithmic two-loop contributions, is identified, and its effect on the maximal value of the lightest CP-even Higgs boson mass is discussed. Finally, we show that in a simple analytic approximation to the Higgs mass, the leading two-loop radiative corrections can be absorbed to a large extent into an effective one-loop expression by evaluating the running top quark mass at appropriately chosen energy scales.

description: We study the emergence and disappearance of defect states in the complex Su-Schrieffer-Heeger (cSSH) model, a non-Hermitian one-dimensional lattice model containing gain and loss on alternating sites. Previous studies of this model have focused on the existence of a non-Hermitian defect state that is localized to the interface between two cSSH domains, and is continuable to the topologically protected defect state of the Hermitian Su-Schrieffer-Heeger (SSH) model. For large gain/loss magnitudes, we find that these defect states can disappear into the continuum, or undergo pairwise spontaneous breaking of a composite sublattice/time-reversal symmetry. The symmetry-breaking transition gives rise to a pair of defect states continuable to non-topologically-protected defect states of the SSH model. We discuss the phase diagram for the defect states, and its implications for non-Hermitian defect states.
