As a famous acupuncturist in the world, professor ZHANG Jin believes the key of acupuncture technique is the use of force, and the understanding of the "concentrating the force into needle body" is essential to understand the essence of acupuncture technique. With deep study of Huangdi Neijing ( The Inner Canon of Huangdi ) and Zhenjiu Dacheng ( Compendium of Acupuncture and Moxibustion ), the author further learned professor ZHANG Jin 's theory and operation specification of "concentrating force into needle body, so the force arriving before and together with needle". The whole-body force should be subtly focused on the tip of needle, and gentle force at tip of needle could get significant reinforcing and reducing effect. In addition, proper timing at tip of needle could start reinforcing and reducing effect, lead qi to disease location, and achieve superior clinical efficacy.

Nutrient starvation is an important survival challenge for bacteria during industrial production of functional foods. As next-generation sequencing technology has greatly advanced, we performed proteomic and genomic analysis to investigate the response of Lactobacillus casei Zhang to a glucose-restricted environment. L. casei Zhang strains were permitted to evolve in glucose-restricted or normal medium from a common ancestor over a 3 year period, and they were sampled at 1000, 2000, 3000, 4000, 5000, 6000, 7000, and 8000 generations and subjected to proteomic and genomic analyses. Genomic resequencing data revealed different point mutations and other mutational events in each selected generation of L. casei Zhang under glucose restriction stress. The differentially expressed proteins induced by glucose restriction were mostly related to fructose and mannose metabolism, carbohydrate metabolic processes, lyase activity, and amino-acid-transporting ATPase activity. Integrative proteomic and genomic analysis revealed that the mutations protected L. casei Zhang against glucose starvation by regulating other cellular carbohydrate, fatty acid, and amino acid catabolism; phosphoenolpyruvate system pathway activation; glycogen synthesis; ATP consumption; pyruvate metabolism; and general stress-response protein expression. The results help reveal the mechanisms of adapting to glucose starvation and provide new strategies for enhancing the industrial utility of L. casei Zhang.

Full Text Available Streptococcus mutans, with the ability of high-rate acid production and strong biofilm formation, is considered the predominant bacterial species in the pathogenesis of human dental caries. Natural products which may be bioactive against S. mutans have become a hot spot to researches to control dental caries. LongZhang Gargle, completely made from Chinese herbs, was investigated for its effects on acid production and biofilm formation by S. mutans in this study. The results showed an antimicrobial activity of LongZhang Gargle against S. mutans planktonic growth at the minimum inhibitory concentration (MIC of 16% and minimum bactericidal concentration (MBC of 32%. Acid production was significantly inhibited at sub-MIC concentrations. Biofilm formation was also significantly disrupted, and 8% was the minimum concentration that resulted in at least 50% inhibition of biofilm formation (MBIC50. A scanning electron microscopy (SEM showed an effective disruption of LongZhang Gargle on S. mutans biofilm integrity. In addition, a confocal laser scanning microscopy (CLSM suggested that the extracellular polysaccharides (EPS synthesis could be inhibited by LongZhang Gargle at a relatively low concentration. These findings suggest that LongZhang Gargle may be a promising natural anticariogenic agent in that it suppresses planktonic growth, acid production, and biofilm formation against S. mutans.

2016-09-01

Tracking the sign of fluctuations governed by the (1+1)-dimensional Kardar-Parisi-Zhang (KPZ) universality class, we show, both experimentally and numerically, that its evolution has an unexpected link to a simple stochastic model called the renewal process, studied in the context of aging and ergodicity breaking. Although KPZ and the renewal process are fundamentally different in many aspects, we find remarkable agreement in some of the time correlation properties, such as the recurrence time distributions and the persistence probability, while the two systems can be different in other properties. Moreover, we find inequivalence between long-time and ensemble averages in the fraction of time occupied by a specific sign of the KPZ-class fluctuations. The distribution of its long-time average converges to nontrivial broad functions, which are found to differ significantly from that of the renewal process, but instead be characteristic of KPZ. Thus, we obtain a new type of ergodicity breaking for such systems with many-body interactions. Our analysis also detects qualitative differences in time-correlation properties of circular and flat KPZ-class interfaces, which were suggested from previous experiments and simulations but still remain theoretically unexplained.

A bandwidth correction to the Allegri-Zhang solution for accelerated random vibration testing

2018-01-01

Full Text Available In 2008, Allegri and Zhang published a study [Int. J. Fatigue. 2008, 30(6:967-977] in which they provided an exact analytical solution to the inverse scaling law for accelerated vibration tests of linear systems submitted to stationary Gaussian excitations By combining finite element analysis with multiaxial spectral methods defined in the frequency-domain, their solution generalised the simple inverse power law model suggested in some standards. The solution adopted the “equivalent von Mises stress” multiaxial criterion combined with the narrow-band damage expression. This work aims to propose a bandwidth correction to the original Allegri-Zhang solution to account for the actual spectral banwidth of the local multiaxial stress. The corrected Allegri-Zhang solution is also extended to another multiaxial spectral method, namely the “Projection-by-Projection” criterion. A numerical example is finally discussed, in which the corrected solution is applied to an L-shaped beam submitted to random accelerations.

Full Text Available Cheddar cheese has been manufactured with Lactobacillus casei Zhang as the dairy starter adjunct. L. casei Zhang had previously been isolated from koumiss collected from Xilin Guole in Inner Mongolia and characterized in detail with regard to their probiotic potential. The addition of L. casei Zhang to Cheddar cheese had no adverse effects on sensory criteria. The cheese made with 0.1, 1 and 2 % of the probiotic strain L. casei Zhang adjuncts contained high levels of the Lactobacillus after 6 months of ripening with final counts of 9.6·10^7, 7.7·10^7 and 1.02·10^8 CFU/g, respectively. In the ripe control cheese, without the addition of probiotic strain L. casei Zhang, the number of Lactobacillus reached 5.7·107 CFU/g. Enterobacterial repetitive intergenic consensus PCR (ERIC-PCR analysis was used to distinguish the added L. casei Zhang from the natural flora of the cheese and to determine whether L. casei Zhang grew in the cheese. ACE-inhibitory activity and γ-aminobutyric acid (GABA concentrations in the cheese were measured. Compared with control cheese, experimental cheese with 0.1, 1 and 2 % of probiotic strain L. casei Zhang revealed some increase in ACE-inhibitory activity and GABA mass fraction. In the present study, the production of both ACE-inhibitory activity and GABA in the probiotic cheese with the L. casei Zhang adjunct isolated from koumiss has been found for the first time. The results suggest that cheese with the probiotic strain L. casei Zhang showed good potential for application in the management of hypertension.

2017-11-01

Full Text Available Lactobacillus (L. casei Zhang is a koumiss-originated probiotic strain, which was used as a model in a long-term antibiotics-driven evolution experiment to reveal bacterial evolutionary dynamics; and we isolated gentamycin-resistant L. casei Zhang descendents. To decipher the gentamycin resistance mechanism, here we cultivated the parental L. casei Zhang and its descendent cells in an antibiotics-containing environment to compare their global protein expression profiles using the iTRAQ-based proteomic approach. A total of 72 proteins were significantly up-regulated (>2.0-fold, P < 0.05, whilst 32 proteins were significantly down-regulated <−2.0-fold, P < 0.05 in the descendent line. The gentamycin-resistant descendent line showed elevated expression in some carbohydrates, amino acids, and purine metabolic pathways. Several stress-related proteins were also differentially expressed. Among them, one alkaline shock protein, asp23, was up-regulated most in the gentamycin-resistant strain (21.9-fold increase compared with the parental strain. The asp23 gene disruption mutant was significantly more sensitive to gentamycin compared with the wild type, suggesting an important role of this gene in developing the gentamycin-resistant phenotype in L. casei. Our report has described the adaptation of a probiotic strain that has acquired antibiotics resistance through long-term antibiotics exposure at the proteome level, and we revealed a novel mechanism of gentamycin resistance.

2010-01-01

A general type of recurrent neural network (termed as Zhang neural network, ZNN) has recently been proposed by Zhang et al for the online solution of time-varying quadratic-minimization (QM) and quadratic-programming (QP) problems. Global exponential convergence of the ZNN could be achieved theoretically in an ideal error-free situation. In this paper, with the normal differentiation and dynamics-implementation errors considered, the robustness properties of the ZNN model are investigated for solving these time-varying problems. In addition, linear activation functions and power-sigmoid activation functions could be applied to such a perturbed ZNN model. Both theoretical-analysis and computer-simulation results demonstrate the good ZNN robustness and superior performance for online time-varying QM and QP problem solving, especially when using power-sigmoid activation functions.

Lyophilization is considered an effective way to preserve the activity of milk starters, such as lactic acid bacteria, in which proper protective agents play key roles. In this study, Lactobacillus casei Zhang, a probiotic bacterium applied as a milk starter in China, was used to investigate the effects of various cryoprotectants according to cell survival rate and physiological characteristics. The result showed a significant survival improvement to 86.6% when glutathione (GSH) was added as an ideal cryoprotectant. Further study revealed that GSH plays a key role on maintaining higher unsaturation ratio of cell membrane and shorter chain length of saturated fatty acids. In this case, the intact cell structure can be obtained. These findings will contribute not only to deepen the understanding of cells during lyophilization but also to improve the industrial performance of certain milk starters such as L. casei Zhang by application of GSH as cryoprotectant.

Space and Intermediality in Jia Zhang-ke’s Still Life

Directory of Open Access Journals (Sweden)

Cecília Mello

2014-07-01

Full Text Available This article is dedicated to an analysis of Chinese director Jia Zhang-ke’s film Still Life (San Xia Hao Ren 三峡好人, 2006 from the point of view of its intermedial relationship with Chinese landscape painting. As I will suggest, Jia’s discovery of a real landscape and a vanishing cityscape in this film, shot on location in the region of the Three Gorges of the Yangtze River, springs from a realist impulse and from an original aesthetic response to a new historical and social conjuncture. But while it seems firmly located in the landscape of contemporary China, the film also shares aesthetic qualities with the tradition of Chinese landscape painting, mounted on hanging or hand scrolls. A focus on this particular instance of intermediality leads to a reflection on cinema’s spatial organization in light of current revisions in film and audiovisual theory, which suggest that filmic space and its spectatorial experience should be considered above all from the point of view of touch and movement. It also allows for a broader understanding of the political implications of intermediality in Jia Zhang-ke’s oeuvre, fruit of an organic link between form and content that brings a historical resonance to a contemporary perspective.

The incidence of colon cancer has increased considerably and the intestinal microbiota participate in the development of colon cancer. We showed that the L. casei Zhang or vitamin K2 (Menaquinone-7) intervention significantly alleviated intestinal tumor burden in mice. This was associated with increased serum adiponectin levels in both treatments. But osteocalcin level was only increased by L. casei Zhang. Furthermore, the anti-carcinogenic actions of L. casei Zhang were mediated by hepatic Chloride channel-3(CLCN3)/Nuclear Factor Kappa B(NF-κB) and intestinal Claudin15/Chloride intracellular channel 4(CLIC4)/Transforming Growth Factor Beta(TGF-β) signaling, while the vitamin K2 effect involved a hepatic Vitamin D Receptor(VDR)-phosphorylated AMPK signaling pathway. Fecal DNA sequencing by the Pacbio RSII method revealed there was significantly lower Helicobacter apodemus, Helicobacter mesocricetorum, Allobaculum stercoricanis and Adlercreutzia equolifaciens following both interventions compared to the model group. Moreover, different caecum acetic acid and butyric acid levels and enrichment of other specific microbes also determined the activity of the different regulatory pathways. Together these data show that L. casei Zhang and Vitamin K2 can suppress gut risk microbes and promote beneficial microbial metabolites to reduce colonic tumor development in mice.

2017-12-01

We obtain several exact results for universal distributions involving the maximum of the Airy2 process minus a parabola and plus a Brownian motion, with applications to the one-dimensional Kardar-Parisi-Zhang (KPZ) stochastic growth universality class. This allows one to obtain (i) the universal limit, for large time separation, of the two-time height correlation for droplet initial conditions, e.g., C∞=limt2/t1→+∞h(t1) h (t2)¯c/h(t1)2¯c, with C∞≈0.623 , as well as conditional moments, which quantify ergodicity breaking in the time evolution; (ii) in the same limit, the distribution of the midpoint position x (t1) of a directed polymer of length t2; and (iii) the height distribution in stationary KPZ with a step. These results are derived from the replica Bethe ansatz for the KPZ continuum equation, with a "decoupling assumption" in the large time limit. They agree and confirm, whenever they can be compared, with (i) our recent tail results for two-time KPZ with the work by de Nardis and Le Doussal [J. Stat. Mech. (2017) 053212, 10.1088/1742-5468/aa6bce], checked in experiments with the work by Takeuchi and co-workers [De Nardis et al., Phys. Rev. Lett. 118, 125701 (2017), 10.1103/PhysRevLett.118.125701] and (ii) a recent result of Maes and Thiery [J. Stat. Phys. 168, 937 (2017), 10.1007/s10955-017-1839-2] on midpoint position.

Zhang neural network for online solution of time-varying convex quadratic program subject to time-varying linear-equality constraints

International Nuclear Information System (INIS)

Zhang Yunong; Li Zhan

2009-01-01

In this Letter, by following Zhang et al.'s method, a recurrent neural network (termed as Zhang neural network, ZNN) is developed and analyzed for solving online the time-varying convex quadratic-programming problem subject to time-varying linear-equality constraints. Different from conventional gradient-based neural networks (GNN), such a ZNN model makes full use of the time-derivative information of time-varying coefficient. The resultant ZNN model is theoretically proved to have global exponential convergence to the time-varying theoretical optimal solution of the investigated time-varying convex quadratic program. Computer-simulation results further substantiate the effectiveness, efficiency and novelty of such ZNN model and method.

Studies have found that the survival of probiotics could be strongly enhanced with dairy products as delivery vehicles, but the molecular mechanism by which this might occur has seldom been mentioned. In this study, microarray technology was used to detect the gene expression profile of Lactobacillus casei Zhang with and without fermented milk used as a delivery vehicle during transit in simulated gastrointestinal juice. Numerous genes of L. casei Zhang in strain suspension were upregulated compared to those from L. casei Zhang in fermented milk. These data might indicate that L. casei Zhang is stimulated directly without the protection of fermented milk, and the high-level gene expression observed here may be a stress response at the transcriptional level. A large proportion of genes involved in translation and cell division were downregulated in the bacteria that were in strain suspension during transit in simulated intestinal juice. This may impede protein biosynthesis and cell division and partially explain the lower viability of L. casei Zhang during transit in the gastrointestinal tract without the delivery vehicle.

A Theta lift representation for the Kawazumi-Zhang and Faltings invariants of genus-two Riemann surfaces

CERN Document Server

Pioline, Boris

2016-01-01

The Kawazumi-Zhang invariant $\\varphi$ for compact genus-two Riemann surfaces was recently shown to be a eigenmode of the Laplacian on the Siegel upper half-plane, away from the separating degeneration divisor. Using this fact and the known behavior of $\\varphi$ in the non-separating degeneration limit, it is shown that $\\varphi$ is equal to the Theta lift of the unique (up to normalization) weak Jacobi form of weight $-2$. This identification provides the complete Fourier-Jacobi expansion of $\\varphi$ near the non-separating node, gives full control on the asymptotics of $\\varphi$ in the various degeneration limits, and provides a efficient numerical procedure to evaluate $\\varphi$ to arbitrary accuracy. It also reveals a mock-type holomorphic Siegel modular form of weight $-2$ underlying $\\varphi$. From the general relation between the Faltings invariant, the Kawazumi-Zhang invariant and the discriminant for hyperelliptic Riemann surfaces, a Theta lift representation for the Faltings invariant in genus two ...

Height distribution tails in the Kardar-Parisi-Zhang equation with Brownian initial conditions

Science.gov (United States)

Meerson, Baruch; Schmidt, Johannes

2017-10-01

For stationary interface growth, governed by the Kardar-Parisi-Zhang (KPZ) equation in 1 + 1 dimensions, typical fluctuations of the interface height at long times are described by the Baik-Rains distribution. Recently Chhita et al (2016 arXiv:1611.06690) used the totally asymmetric simple exclusion process (TASEP) to study the height fluctuations in systems of the KPZ universality class for Brownian interfaces with arbitrary diffusion constant. They showed that there is a one-parameter family of long-time distributions, parameterized by the diffusion constant of the initial random height profile. They also computed these distributions numerically by using Monte Carlo (MC) simulations. Here we address this problem analytically and focus on the distribution tails at short times. We determine the (stretched exponential) tails of the height distribution by applying the optimal fluctuation method (OFM) to the KPZ equation. We argue that, by analogy with other initial conditions, the ‘slow’ tail holds at arbitrary times and therefore provides a proper asymptotic to the family of long-time distributions studied in Chhita et al (2016 arXiv:1611.06690). We verify this hypothesis by performing large-scale MC simulations of a TASEP with a parallel-update rule. The ‘fast’ tail, predicted by the OFM, is also expected to hold at arbitrary times, at sufficiently large heights.

Full Text Available The Internet, high-speed electronic communications, and computers have transformed the way we teach and learn. With the development of these new information and communication technologies, the idea of online education has been adopted in many developed, and more recently in developing countries, to bring wider opportunities to people in the form of increased access to flexible and interactive, open and distance learning systems. As stated in the Introduction of “Advancing Online Learning in Asia” edited by Murphy, Shin, and Zhang, online education is now everywhere and it “is changing the ways in which educational institutions interact with their students, for both traditional and distance education universities.” By examining recent developments of online education in Asia from multiple perspectives, this book has a potential to be an invaluable resource to educators. Taking cases from the Asian region in which online learning was introduced, implemented, and experienced, this book presents the cases from a number of perspectives, especially from student perspectives, and addresses pedagogical and technical issues faced by online educators. The breadth of the articles in this book provides a wide range of online learning cases and varied perspectives, which should clearly appeal to educators, researchers, administrators, and policy makers in online education.

We consider the follow-the-leader approximation of the Aw-Rascle-Zhang (ARZ) model for traffic flow in a multi population formulation. We prove rigorous convergence to weak solutions of the ARZ system in the many particle limit in presence of vacuum. The result is based on uniform BV estimates on the discrete particle velocity. We complement our result with numerical simulations of the particle method compared with some exact solutions to the Riemann problem of the ARZ system.

A Chinese View on the Cultural Conditionality of Logic and Epistemology: Zhang Dongsun’s Intercultural Methodology

Directory of Open Access Journals (Sweden)

Jana Rošker

2010-12-01

Full Text Available Recognizing the fact that comprehension, analysis and transmission of reality are based on diversely structured socio-political contexts as well as on different categorical and essential postulates, offers a prospect of enrichment. Thus, this article presents an analysis and interpretation of one of the first Chinese theoreticians, working in the field of intercultural methodology. Although Zhang Dongsun (1886–1973 can be considered as one of the leading Chinese philosophers of the 20th Century, his criticism of Sinicized Marxist ideologies marked him as a political dissident and he was consequently consigned to oblivion for several decades; only recently has his work been rediscovered by a number of younger Chinese theorists, who have shown a growing interest in his ideas. Although he is still relatively unknown in the West, Zhang definitely deserves to be recognized for his contributions to Chinese and comparative philosophy. The present article focuses on his extraordinary ability to introduce Western thought in a way which was compatible with the specific methodology of traditional Chinese thought. According to such presumptions, culture is viewed as an entity composed of a number of specific discourses and relations. The article shows how the interweaving and interdependence of these discourses form different cultural backgrounds, which manifest themselves in the specific, culturally determined structures of language and logic. It also explains the role of traditional elements in his cultural epistemology.

Reply to comment by Ma and Zhang on "Rescaling the complementary relationship for land surface evaporation"

Science.gov (United States)

Crago, Richard; Qualls, Russell; Szilagyi, Jozsef; Huntington, Justin

2017-07-01

Ma and Zhang (2017) note a concern they have with our rescaled Complementary Relationship (CR) for land surface evaporation when daily average wind speeds are very low (perhaps less than 1 m/s). We discuss conditions and specific formulations that lead to this concern, but ultimately argue that under these conditions, a key assumption behind the CR itself may not be satisfied at the daily time scale. Thus, careful consideration of the reliability of the CR is needed when wind speeds are very low.

Acceleration of black hole universe

Science.gov (United States)

Zhang, T. X.; Frederick, C.

2014-01-01

Recently, Zhang slightly modified the standard big bang theory and developed a new cosmological model called black hole universe, which is consistent with Mach's principle, governed by Einstein's general theory of relativity, and able to explain all observations of the universe. Previous studies accounted for the origin, structure, evolution, expansion, and cosmic microwave background radiation of the black hole universe, which grew from a star-like black hole with several solar masses through a supermassive black hole with billions of solar masses to the present state with hundred billion-trillions of solar masses by accreting ambient matter and merging with other black holes. This paper investigates acceleration of the black hole universe and provides an alternative explanation for the redshift and luminosity distance measurements of type Ia supernovae. The results indicate that the black hole universe accelerates its expansion when it accretes the ambient matter in an increasing rate. In other words, i.e., when the second-order derivative of the mass of the black hole universe with respect to the time is positive . For a constant deceleration parameter , we can perfectly explain the type Ia supernova measurements with the reduced chi-square to be very close to unity, χ red˜1.0012. The expansion and acceleration of black hole universe are driven by external energy.

Le langage des couleurs dans les films de Zhang Yimou

Directory of Open Access Journals (Sweden)

Xiaomin Giafferri

2009-05-01

Full Text Available Tout film, ou du moins tout film de fiction, est récit. Représentation visuelle et sonore, le film transpose à l’écran la réalité par un enchaînement d’images, où des traits physiques, gestes, mouvements, paysages se combinent pour former un espace de fiction. Le cinéma en tant qu’art possède un langage spécifique ; dans un film coloré, les couleurs comme moyen d’expression font partie du langage pictural. A partir de quatre films de Zhang Yimou connus en Europe, Le sorgho rouge, Epouses et concubines, Judou et Hero, ce texte tente de réfléchir sur ces questions: si l’on admet que les limites du récit filmique diffèrent de celles du récit verbal, romanesque par exemple, les couleurs qui ne constituent pas un trait pertinent d’identification, participent-elle à la prise en charge de l’histoire ? Composante de l’espace filmique dont les fonctions narratives sont incontestées, sont-elle définitivement non diégétiques ?

Recent developments on the Kardar-Parisi-Zhang surface-growth equation.

Science.gov (United States)

Wio, Horacio S; Escudero, Carlos; Revelli, Jorge A; Deza, Roberto R; de la Lama, Marta S

2011-01-28

The stochastic nonlinear partial differential equation known as the Kardar-Parisi-Zhang (KPZ) equation is a highly successful phenomenological mesoscopic model of surface and interface growth processes. Its suitability for analytical work, its explicit symmetries and its prediction of an exact dynamic scaling relation for a one-dimensional substratum led people to adopt it as a 'standard' model in the field during the last quarter of a century. At the same time, several conjectures deserving closer scrutiny were established as dogmas throughout the community. Among these, we find the beliefs that 'genuine' non-equilibrium processes are non-variational in essence, and that the exactness of the dynamic scaling relation owes its existence to a Galilean symmetry. Additionally, the equivalence among planar and radial interface profiles has been generally assumed in the literature throughout the years. Here--among other topics--we introduce a variational formulation of the KPZ equation, remark on the importance of consistency in discretization and challenge the mainstream view on the necessity for scaling of both Galilean symmetry and the one-dimensional fluctuation-dissipation theorem. We also derive the KPZ equation on a growing domain as a first approximation to radial growth, and outline the differences with respect to the classical case that arises in this new situation.

Reflected Brownian motions in the KPZ universality class

CERN Document Server

Weiss, Thomas; Spohn, Herbert

2017-01-01

This book presents a detailed study of a system of interacting Brownian motions in one dimension. The interaction is point-like such that the n-th Brownian motion is reflected from the Brownian motion with label n-1. This model belongs to the Kardar-Parisi-Zhang (KPZ) universality class. In fact, because of the singular interaction, many universal properties can be established with rigor. They depend on the choice of initial conditions. Discussion addresses packed and periodic initial conditions (Chapter 5), stationary initial conditions (Chapter 6), and mixtures thereof (Chapter 7). The suitably scaled spatial process will be proven to converge to an Airy process in the long time limit. A chapter on determinantal random fields and another one on Airy processes are added to have the notes self-contained. These notes serve as an introduction to the KPZ universality class, illustrating the main concepts by means of a single model only. The notes will be of interest to readers from interacting diffusion processe...

Generalized One-Band Model Based on Zhang-Rice Singlets for Tetragonal CuO

Science.gov (United States)

Hamad, I. J.; Manuel, L. O.; Aligia, A. A.

2018-04-01

Tetragonal CuO (T-CuO) has attracted attention because of its structure similar to that of the cuprates. It has been recently proposed as a compound whose study can give an end to the long debate about the proper microscopic modeling for cuprates. In this work, we rigorously derive an effective one-band generalized t -J model for T-CuO, based on orthogonalized Zhang-Rice singlets, and make an estimative calculation of its parameters, based on previous ab initio calculations. By means of the self-consistent Born approximation, we then evaluate the spectral function and the quasiparticle dispersion for a single hole doped in antiferromagnetically ordered half filled T-CuO. Our predictions show very good agreement with angle-resolved photoemission spectra and with theoretical multiband results. We conclude that a generalized t -J model remains the minimal Hamiltonian for a correct description of single-hole dynamics in cuprates.

Thinking Styles and Quality of University Life Among Deaf or Hard of Hearing and Hearing Students.

Science.gov (United States)

Cheng, Sanyin; Zhang, Li-Fang

2017-01-01

The authors explored how thinking styles relate to quality of university life among deaf or hard of hearing (DHH) and hearing university students in mainland China. The first of two studies affirmed the validity and reliability of a modified version of the Quality of University Life Measure (QULM; Sirgy, Grezskowiak, & Rahtz, 2007) among 833 university students (366 DHH, 467 hearing). The second investigated relationships between thinking styles and quality of university life; the Thinking Styles Inventory-Revised II (Sternberg, Wagner, & Zhang, 2007) and modified QULM were administered to 542 students (256 DHH, 286 hearing). Students scoring higher on Type I styles (i.e., more creativity-generating, less structured, cognitively more complex) tended toward greater satisfaction with university life; those scoring higher on Type II (i.e., more norm-favoring, more structured, cognitively more simplistic) tended toward less satisfaction. Contributions, limitations, and implications of the research are discussed.

Finite-size effects in the short-time height distribution of the Kardar-Parisi-Zhang equation

Science.gov (United States)

Smith, Naftali R.; Meerson, Baruch; Sasorov, Pavel

2018-02-01

We use the optimal fluctuation method to evaluate the short-time probability distribution P(H, L, t) of height at a single point, H=h(x=0, t) , of the evolving Kardar-Parisi-Zhang (KPZ) interface h(x, t) on a ring of length 2L. The process starts from a flat interface. At short times typical (small) height fluctuations are unaffected by the KPZ nonlinearity and belong to the Edwards-Wilkinson universality class. The nonlinearity, however, strongly affects the (asymmetric) tails of P(H) . At large L/\\sqrt{t} the faster-decaying tail has a double structure: it is L-independent, -\\lnP˜≤ft\\vert H\\right\\vert 5/2/t1/2 , at intermediately large \\vert H\\vert , and L-dependent, -\\lnP˜ ≤ft\\vert H\\right\\vert 2L/t , at very large \\vert H\\vert . The transition between these two regimes is sharp and, in the large L/\\sqrt{t} limit, behaves as a fractional-order phase transition. The transition point H=Hc+ depends on L/\\sqrt{t} . At small L/\\sqrt{t} , the double structure of the faster tail disappears, and only the very large-H tail, -\\lnP˜ ≤ft\\vert H\\right\\vert 2L/t , is observed. The slower-decaying tail does not show any L-dependence at large L/\\sqrt{t} , where it coincides with the slower tail of the GOE Tracy-Widom distribution. At small L/\\sqrt{t} this tail also has a double structure. The transition between the two regimes occurs at a value of height H=Hc- which depends on L/\\sqrt{t} . At L/\\sqrt{t} \\to 0 the transition behaves as a mean-field-like second-order phase transition. At \\vert H\\vert c-\\vert the slower tail behaves as -\\lnP˜ ≤ft\\vert H\\right\\vert 2L/t , whereas at \\vert H\\vert >\\vert H_c-\\vert it coincides with the slower tail of the GOE Tracy-Widom distribution.

China marks World Population Day. Address by Zhang Weiqing: (Excerpts).

Science.gov (United States)

Zhang, W

1998-08-01

This is a summary of remarks by Minister Zhang Weiqing of China's State Family Planning Commission (SFPC) given on World Population Day in China. The world's population size has increased by 1 billion since 1987, and will reach 6 billion by 1999. As the most populous developing country in the world, China has a greater population pressure and bears a large responsibility regarding stabilization of the world's population and realization of sustainable development. China has a less developed economy and a high percentage of rural and illiterate persons, many of whom are below the poverty line. The interests of both present and future generations must be taken into account with regard to development. In addition, the modernization drive must include strategies for sustainable development and basic national policies of FP and environmental protection in order to achieve a balance among population growth, the economy, resources, and the environment. After 30 years of effort, China has succeeded in solving its population problem by integrating governmental guidance with voluntary public participation in FP. In 1997, the birthrate decreased to 16.57/1000, and the total fertility rate was below replacement level. Changes in attitude toward marriage and childbearing have occurred, as has awareness of voluntary participation in FP. However, some problems have emerged in the implementation of population and FP programs. China will carry out its programs strictly and effectively while developing the national economy. Goals include: 1) stressing the IEC program regarding contraception and regular FP management and services; 2) integrating the FP program with economic development; 3) helping the public to become well off; 4) protecting maternal and child health; 5) improving the status of women; 6) delivering reproductive services; and 7) improving social security measures. Efforts will be made to enable the public to have a more active part in implementing the FP program.

Genet. Mol. Res. 15: gmr.15025866. Two major concerns were found in this article. Firstly, it was found to be substantially equal to the article "Tumor necrosis factor-alpha gene -308G > A polymorphism alters the risk of hepatocellular carcinoma in a Han Chinese population" published in the Diagnostic Pathology Diagnostic Pathology (2014) 9: 199, by Feng et al.; licensee BioMed Central. 2014 - DOI: 10.1186/s13000-014-0199-3. Secondly, the authors do not discuss limitations of their approaches in the discussion. The discussion is largely an elaboration of the literature in the introduction part. However, even in that context, the discussion does not appropriately review the literature and there are frequent references to conclusions that are not supported by the cited literature. The GMR editorial staff was alerted and after a thorough investigation, there is strong reason to believe that the peer review process was failure. Also, after review and contacting the authors, the editors of Genetics and Molecular Research decided to retract this article in accordance with the recommendations of the Committee on Publication Ethics (COPE). The authors and their institutions were advised of this serious breach of ethics.

A pedestrian's view on interacting particle systems, KPZ universality and random matrices

International Nuclear Information System (INIS)

Kriecherbauer, Thomas; Krug, Joachim

2010-01-01

These notes are based on lectures delivered by the authors at a Langeoog seminar of SFB/TR12 Symmetries and Universality in Mesoscopic Systems to a mixed audience of mathematicians and theoretical physicists. After a brief outline of the basic physical concepts of equilibrium and nonequilibrium states, the one-dimensional simple exclusion process is introduced as a paradigmatic nonequilibrium interacting particle system. The stationary measure on the ring is derived and the idea of the hydrodynamic limit is sketched. We then introduce the phenomenological Kardar-Parisi-Zhang (KPZ) equation and explain the associated universality conjecture for surface fluctuations in growth models. This is followed by a detailed exposition of a seminal paper of Johansson [59] that relates the current fluctuations of the totally asymmetric simple exclusion process (TASEP) to the Tracy-Widom distribution of random matrix theory. The implications of this result are discussed within the framework of the KPZ conjecture. (topical review)

We study height fluctuations of interfaces in the (1 +1 ) -dimensional Kardar-Parisi-Zhang (KPZ) class, growing at different speeds in the left half and the right half of space. Carrying out simulations of the discrete polynuclear growth model with two different growth rates, combined with the standard setting for the droplet, flat, and stationary geometries, we find that the fluctuation properties at and near the boundary are described by the KPZ half-space problem developed in the theoretical literature. In particular, in the droplet case, the distribution at the boundary is given by the largest-eigenvalue distribution of random matrices in the Gaussian symplectic ensemble, often called the GSE Tracy-Widom distribution. We also characterize crossover from the full-space statistics to the half-space one, which arises when the difference between the two growth speeds is small.

Gamma ray bursts of black hole universe

Science.gov (United States)

Zhang, T. X.

2015-07-01

Slightly modifying the standard big bang theory, Zhang recently developed a new cosmological model called black hole universe, which has only a single postulate but is consistent with Mach's principle, governed by Einstein's general theory of relativity, and able to explain existing observations of the universe. In the previous studies, we have explained the origin, structure, evolution, expansion, cosmic microwave background radiation, quasar, and acceleration of black hole universe, which grew from a star-like black hole with several solar masses through a supermassive black hole with billions of solar masses to the present state with hundred billion-trillions of solar masses by accreting ambient matter and merging with other black holes. This study investigates gamma ray bursts of black hole universe and provides an alternative explanation for the energy and spectrum measurements of gamma ray bursts according to the black hole universe model. The results indicate that gamma ray bursts can be understood as emissions of dynamic star-like black holes. A black hole, when it accretes its star or merges with another black hole, becomes dynamic. A dynamic black hole has a broken event horizon and thus cannot hold the inside hot (or high-frequency) blackbody radiation, which flows or leaks out and produces a GRB. A star when it collapses into its core black hole produces a long GRB and releases the gravitational potential energy of the star as gamma rays. A black hole that merges with another black hole produces a short GRB and releases a part of their blackbody radiation as gamma rays. The amount of energy obtained from the emissions of dynamic star-like black holes are consistent with the measurements of energy from GRBs. The GRB energy spectra derived from this new emission mechanism are also consistent with the measurements.

These notes are based on lectures delivered by the authors at a Langeoog seminar of SFB/TR12 Symmetries and Universality in Mesoscopic Systems to a mixed audience of mathematicians and theoretical physicists. After a brief outline of the basic physical concepts of equilibrium and nonequilibrium states, the one-dimensional simple exclusion process is introduced as a paradigmatic nonequilibrium interacting particle system. The stationary measure on the ring is derived and the idea of the hydrodynamic limit is sketched. We then introduce the phenomenological Kardar-Parisi-Zhang (KPZ) equation and explain the associated universality conjecture for surface fluctuations in growth models. This is followed by a detailed exposition of a seminal paper of Johansson [59] that relates the current fluctuations of the totally asymmetric simple exclusion process (TASEP) to the Tracy-Widom distribution of random matrix theory. The implications of this result are discussed within the framework of the KPZ conjecture. (topical review)

Quasar Formation and Energy Emission in Black Hole Universe

Directory of Open Access Journals (Sweden)

Zhang T. X.

2012-07-01

Full Text Available Formation and energy emission of quasars are investigated in accord with the black hole universe, a new cosmological model recently developed by Zhang. According to this new cosmological model, the universe originated from a star-like black hole and grew through a supermassive black hole to the present universe by accreting ambient matter and merging with other black holes. The origin, structure, evolution, expansion, and cosmic microwave background radiation of the black hole universe have been fully ex- plained in Paper I and II. This study as Paper III explains how a quasar forms, ignites and releases energy as an amount of that emitted by dozens of galaxies. A main sequence star, after its fuel supply runs out, will, in terms of its mass, form a dwarf, a neutron star, or a black hole. A normal galaxy, after its most stars have run out of their fuels and formed dwarfs, neutron stars, and black holes, will eventually shrink its size and collapse towards the center by gravity to form a supermassive black hole with billions of solar masses. This collapse leads to that extremely hot stellar black holes merge each other and further into the massive black hole at the center and meantime release a huge amount of radiation energy that can be as great as that of a quasar. Therefore, when the stellar black holes of a galaxy collapse and merge into a supermassive black hole, the galaxy is activated and a quasar is born. In the black hole universe, the observed dis- tant quasars powered by supermassive black holes can be understood as donuts from the mother universe. They were actually formed in the mother universe and then swallowed into our universe. The nearby galaxies are still very young and thus quiet at the present time. They will be activated and further evolve into quasars after billions of years. At that time, they will enter the universe formed by the currently observed distant quasars as similar to the distant quasars entered our universe

Clothianidin is a second-generation neonicotinoid insecticide that is quite effective against Bradysia odoriphaga Yang and Zhang, the major insect pest affecting Chinese chive in northern China. In this study, the dissipation of clothianidin in soil and its residue in leaves and pseudostems/bulbs as well as its control efficacy against B. odoriphaga and two other secondary pests were investigated in Chinese chive fields after soil application of clothianidin by the directional spray-washing method. The half-life of clothianidin was 35.73-36.10 days, and it could be detected in Chinese chive plants in both treatment plots up to 240 days after a single soil application. Clothianidin applied at 3.0 and 6.0 kg AI ha(-1) could suppress B. odoriphaga population growth, achieve satisfactory levels of pest control for almost 10 months and reduce the losses of the yield in winter. Moreover, the treatments also significantly reduced Thrips alliorum and Acrolepia alliella populations up to nearly 180 days after one application. Clothianidin can be considered to show long-lasting efficacy against B. odoriphaga and to be safe for use in Chinese chive at 3.0 and 6.0 kg AI ha(-1) once in the early root-rearing period to control B. odoriphaga in these cultivation ecosystems. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

Therefore, aqueous solutions of SWNT, designed by noncovalent functionalization and without toxicity, are required for biomedical applications. Methods: In this study, we conjugated docetaxel with SWNT via p-p accumulation and used a surfactant to functionalize SWNT noncovalently. The SWNT were then conjugated with docetaxel (DTX-SWNT and linked with NGR (Asn-Gly-Arg peptide, which targets tumor angiogenesis, to obtain a water-soluble and tumor-targeting SWNT-NGR-DTX drug delivery system. Results: SWNT-NGR-DTX showed higher efficacy than docetaxel in suppressing tumor growth in a cultured PC3 cell line in vitro and in a murine S180 cancer model. Tumor volumes in the S180 mouse model decreased considerably under near-infrared radiation compared with the control group. Conclusion: The SWNT-NGR-DTX drug delivery system may be promising for high treatment efficacy with minimal side effects in future cancer therapy.

Universality in driven-dissipative quantum many-body systems

International Nuclear Information System (INIS)

Sieberer, L.M.

2015-01-01

Recent experimental investigations of condensation phenomena in driven-dissipative quantum many-body systems raise the question of what kind of novel universal behavior can emerge under non-equilibrium conditions. We explore various aspects of universality in this context. Our results are of relevance for a variety of open quantum systems on the interface of quantum optics and condensed matter physics, ranging from exciton-polariton condensates to cold atomic gases. In Part I we characterize the dynamical critical behavior at the Bose-Einstein condensation phase transition in driven open quantum systems in three spatial dimensions. Although thermodynamic equilibrium conditions are emergent at low frequencies, the approach to this thermalized low-frequency regime is described by a critical exponent which is specific to the non-equilibrium transition, and places the latter beyond the standard classification of equilibrium dynamical critical behavior. Our theoretical approach is based on the functional renormalization group within the framework of Keldysh non-equilibrium field theory, which is equivalent to a microscopic description of the open system dynamics in terms of a many-body quantum master equation. Universal behavior in the coherence properties of driven-dissipative condensates in reduced dimensions is investigated in Part II. We show that driven two-dimensional Bose systems cannot exhibit algebraic order as in thermodynamic equilibrium, unless they are sufficiently anisotropic. However, we find evidence that even isotropic systems may have a finite superfluidity fraction. In one-dimensional systems, non-equilibrium conditions are traceable in the behavior of the autocorrelation function. We obtain these results by mapping the long-wavelength condensate dynamics onto the Kardar-Parisi-Zhang equation. In Part III we show that systems in thermodynamic equilibrium have a specific symmetry, which makes them distinct from generic driven open systems. The novel

Mg2+ improves the thermotolerance of probiotic Lactobacillus rhamnosus GG, Lactobacillus casei Zhang and Lactobacillus plantarum P-8.

Food-related carbohydrates and proteins are often used as thermoprotectants for probiotic lactobacilli during industrial production and processing. However, the effect of inorganic salts is rarely reported. Magnesium is the second-most abundant cation in bacteria, and commonly found in various foods. Mg 2+ homeostasis is important in Salmonella and has been reported to play a critical role in their thermotolerance. However, the role of Mg 2+ in thermotolerance of other bacteria, in particular probiotic bacteria, still remains a hypothesis. In this study, the effect of Mg 2+ on thermotolerance of probiotic lactobacilli was investigated in three well-documented probiotic strains, Lactobacillus rhamnosus GG, Lactobacillus casei Zhang and Lactobacillus plantarum P-8, in comparison with Zn 2+ and Na + . Concentrations of Mg 2+ between 10 and 50 mmol l -1 were found to increase the bacterial survival upon heat challenge. Remarkably, Mg 2+ addition at 20 mmol l -1 led to a 100-fold higher survival of L. rhamnosus GG upon heat challenge. This preliminary study also showed that Mg 2+ shortened the heat-induced extended lag time of bacteria, which indicated the improvement in bacterial recovery from thermal injury. In order to improve the productivity and stability of live probiotics, extensive investigations have been carried out to improve thermotolerance of probiotics. However, most of these studies focused on the effects of carbohydrates, proteins or amino acids. The roles of inorganic salts in various food materials, which have rarely been reported, should be considered when incorporating probiotics into these foods. In this study, Mg 2+ was found to play a significant role in the thermotolerance of probiotic lactobacilli. A novel strategy may be available in the near future by employing magnesium salts as protective agents of probiotics during manufacturing process. © 2017 The Society for Applied Microbiology.

This nanosystem, named PDF nanoparticles, consisted of phospholipid/Pluronic F68 complex nanocores and pullulan shells. IR780 and paclitaxel were loaded separately into PDF nanoparticles to form PDFI and PDFP nanoparticles, which had regular sphere shapes and relatively small sizes. Upon near-infrared laser irradiation at 808 nm, PDFI nanoparticles showed strong PTT/PDT efficacy both in vitro and in vivo. In MHCC-97H cells, the combined treatment of PDFI nanoparticles/laser irradiation and PDFP nanoparticles exhibited significant synergistic effects on inhibiting cell proliferation and inducing cell apoptosis and cell cycle arrest at G2/M phase. In MHCC-97H tumor-bearing mice, PDFI nanoparticles exhibited excellent HCC-targeting and accumulating capability after intravenous injection. Furthermore, the combined treatment of PDFI nanoparticles/laser irradiation and PDFP nanoparticles also effectively inhibited the tumor growth and the tumor angiogenesis in MHCC-97H tumor-bearing mice. In summary, we put forward a therapeutic

The reconstituted HDL nanoparticles had structural similarity to native HDL, and could be taken up by HepG2 cells via interaction with HDL receptors in vitro. In vivo MRI studies in rats after intravenous injections of 10 µmol gadolinium per kg of recombinant HDL nanoparticles indicated that both nanoparticles could provide signal enhancement in the liver and related organs. However, different T1-weighted image details suggested that they participated in different cholesterol metabolism and excretion pathways in the liver.Conclusion: Such information could be highly useful to differentiate functional changes as well as anatomic differences in the liver. These cholesterol-derived contrast agents and their recombinant HDL preparations may warrant further development as a new class of contrast agents for MRI of the liver and related organs.Keywords: magnetic resonance imaging, apolipoprotein, high-density lipoprotein, contrast agent, gadolinium, liver

Various reagents have been applied in the treatment of skin chemical burns; however, no optimal reagent for skin chemical burns currently exists. The present study investigated the effect of topical body protective compound (BPC-157 treatment on skin wound healing, using an alkali burn rat model. Topical treatment with BPC-157 was shown to accelerate wound closure following an alkali burn. Histological examination of skin sections with hematoxylin–eosin and Masson staining showed better granulation tissue formation, reepithelialization, dermal remodeling, and a higher extent of collagen deposition when compared to the model control group on the 18th day postwounding. BPC-157 could promote vascular endothelial growth factor expression in wounded skin tissues. Furthermore, 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide and cell cycle analysis demonstrated that BPC-157 enhanced the proliferation of human umbilical vein endothelial cells (HUVECs. Transwell assay and wound healing assay showed that BPC-157 significantly promoted migration of HUVECs. We also observed that BPC-157 upregulated the expression of VEGF-a and accelerated vascular tube formation in vitro. Moreover, further studies suggested that BPC-157 regulated the phosphorylation level of

The as-prepared I-doped CDs are monodispersed spherical nanoparticles (a diameter of ~2.7 nm with favorable dispersibility and colloidal stability in water. The aqueous solution of I-doped CDs showed wavelength-dependent excitation and stable photoluminescence similar to traditional carbon quantum dots. Importantly, I-doped CDs displayed superior X-ray attenuation properties in vitro and excellent biocompatibility. After intravenous injection, I-doped CDs were distributed throughout the body and excreted by renal clearance. These findings validated that I-doped CDs with high X-ray attenuation potency and favorable photoluminescence show great promise for biomedical research and disease diagnosis.

Qiao et al. (2016) commented on our work (Zhang et al., 2014) and rejected our reinterpretation of the magnetostratigraphic results of Huang et al. (2006) and Li et al. (2006), with the results gained using the Dynamic Time Warping Algorithm technique (DTWAT) as their main basis. However, Qiao et al. (2016) did not provide details of their modeling inputs, and, in particular, the parameters they chose for their calculations, where such parameters can have a serious impact upon any results. We therefore performed calculations using the same software (i.e., Qupydon) as Qiao et al. (2016), using reliable parameter settings. The results showed that the ;interesting correlation; of a 6000 minimum cost output completely correlate with the magnetostratigraphic Chrons C18r to C3An.1n ( 40-6 Ma), which is consistent with our reinterpreted magnetostratigraphic results. Furthermore, we summarized previous biostratigraphic studies of nearby areas; the data resulting from this process also supported our reinterpreted magnetostratigraphic correlation. We were therefore able to confirm the revised magnetostratigraphic correlation of Zhang et al. (2014).

Universal screening as the great equalizer: Eliminating disproportionality in special education referrals

Science.gov (United States)

Raines, Tara C.

The overrepresentation of minority students identified for special education services continues to plague schools and serves as a challenge for researchers and practitioners (Ferri & Conner, 2005). Teacher nomination, office discipline referrals (ODR), and functional behavior assessments (FBA) continue to guide referral processes (Bradshaw, Mitchell, O'Brennen, & Leaf, 2010; Eklund, et al., 2009; Mustian, 2010). These methods have been found to be riddled with inconsistencies. Practices used to identify students for behavioral and emotional interventions over-identify students from culturally and linguistically diverse backgrounds. The use of a behavioral and emotional screener to make data-based decisions regarding placement and services could provide an objective assessment of student risk. The first chapter of this dissertation reviews methods used in the identification of students for behavioral and emotional support services. Additionally, the use of universal screening in conjunction with student self-report are proposed as tools for alleviating the overrepresentation of minority students in special education programs for behavioral and emotional disorders. The second chapter of this dissertation explores the measurement equivalence of Behavior Assessment System for Children, Second Edition (BASC-2) Behavioral and Emotional Screening System Student form (BESS Student) across the Black, Hispanic, and White participants in the norming sample. The BESS Student as a universal screening tool is poised to alleviate the disproportionate number of children of color identified by schools as having behavior and emotional disorders. This instrument also provides an avenue to identify students with internalizing disorders who are often overlooked in present referral practices (Bradshaw, Buckley, & Ialongo, 2008; Kataoka, Zhang, & Wells, 2002). The findings of the measurement equivalence study suggests that the BESS Student is, as designed, identifying behavioral and

Realistic modeling of cumulus convection at fine model resolutions (a few to a few tens of km) is problematic since it requires the cumulus scheme to adapt to higher resolution than they were originally designed for (~100 km). To solve this problem, we implement the spatial averaging method proposed in Xiao et al. (2015) and also propose a temporal averaging method for the large-scale convective available potential energy (CAPE) tendency in the Zhang-McFarlane (ZM) cumulus parameterization. The resolution adaptability of the original ZM scheme, the scheme with spatial averaging, and the scheme with both spatial and temporal averaging at 4-32 km resolution is assessed using the Weather Research and Forecasting (WRF) model, by comparing with Cloud Resolving Model (CRM) results. We find that the original ZM scheme has very poor resolution adaptability, with sub-grid convective transport and precipitation increasing significantly as the resolution increases. The spatial averaging method improves the resolution adaptability of the ZM scheme and better conserves the total transport of moist static energy and total precipitation. With the temporal averaging method, the resolution adaptability of the scheme is further improved, with sub-grid convective precipitation becoming smaller than resolved precipitation for resolution higher than 8 km, which is consistent with the results from the CRM simulation. Both the spatial distribution and time series of precipitation are improved with the spatial and temporal averaging methods. The results may be helpful for developing resolution adaptability for other cumulus parameterizations that are based on quasi-equilibrium assumption.

However, no effective treatments for the same have been developed so far. Humanin (HN is a 24-amino acid peptide originally cloned from the brain of patients with AD and it prevents stress-induced cell death in many cells/tissues. In our previous study, HN was found to effectively rescue rat cortical neurons. It is still not clear whether HN protects the neurons through the attenuation of mitochondrial dysfunction. In this study, excitatory toxicity was induced by NMDA, which binds the NMDA receptor in primarily cultured rat cortical neurons. We found that NMDA (100 µmol/L dramatically induced the decrease of cell viability and caused mitochondrial dysfunction. Pretreatment of the neurons with HN (1 µmol/L led to significant increases of mitochondrial succinate dehydrogenase (SDH activity and membrane potential. In addition, HN pretreatment significantly reduced the excessive production of both reactive oxygen species (ROS and nitric

Although inflammation has an important role in the pathogenesis of chronic obstructive pulmonary disease (COPD, little is known regarding the relationship between serum CyPA and COPD. Methods: Ninety-three COPD patients with acute exacerbation were enrolled in the study and were reassessed during the convalescence phase. Eighty-eight controls were matched for age, gender, body mass index, smoking index and comorbidity. The basic clinical information and pulmonary function of all participants were collected. Serum levels of CyPA and other inflammation indexes were further measured. Results: Serum CyPA was significantly increased in convalescent COPD patients compared to healthy controls, and further elevated in COPD patients with acute exacerbation. Serum CyPA positively correlated with serum interleukin-6, matrix metalloproteinase-9 and high-sensitivity C-reactive protein in both the exacerbation and convalescence phases of COPD. Furthermore, it negatively correlated with percent value of forced expiratory volume in 1 second (FEV1% predicted and FEV1/forced vital capacity in convalescent COPD patients. Conclusion: These results suggest that serum CyPA can be used as a potential inflammatory biomarker for COPD and assessment of serum CyPA may reflect the severity of inflammation in COPD. Keywords: cyclophilin A, chronic obstructive pulmonary disease

Lactobacillus casei has traditionally been recognized as a probiotic and frequently used as an adjunct culture in fermented dairy products, where acid stress is an environmental condition commonly encountered. In the present study, we carried out a comparative physiological and proteomic study to investigate lactic-acid-induced alterations in Lactobacillus casei Zhang (WT) and its acid-resistant mutant. Analysis of the physiological data showed that the mutant exhibited 33.8% higher glucose phosphoenolpyruvate:sugar phosphotransferase system activity and lower glycolytic pH compared with the WT under acidic conditions. In addition, significant differences were detected in both cells during acid stress between intracellular physiological state, including intracellular pH, H(+)-ATPase activity, and intracellular ATP pool. Comparison of the proteomic data based on 2D-DIGE and i-TRAQ indicated that acid stress invoked a global change in both strains. The mutant protected the cells against acid damage by regulating the expression of key proteins involved in cellular metabolism, DNA replication, RNA synthesis, translation, and some chaperones. Proteome results were validated by Lactobacillus casei displaying higher intracellular aspartate and arginine levels, and the survival at pH 3.3 was improved 1.36- and 2.10-fold by the addition of 50-mM aspartate and arginine, respectively. To our knowledge, this is the first demonstration that aspartate may be involved in acid tolerance in Lactobacillus casei. Results presented here may help us understand acid resistance mechanisms and help formulate new strategies to enhance the industrial applications of this species.

Exploration of the relationship between geographical environment and human diseases in ancient China.

Science.gov (United States)

Zhu, Jian-Ping

2011-12-01

The Yellow Emperor's Classic of Internal Medicine, created in the Warring States period (475 to 221 BC) described a phenomenon whereby the eastern, western, northern, southern, and central regions were liable to different diseases. It brought forward the principle of treatment in accordance with local conditions. Lv's Spring and Autumn Annals, Huai Nan Tzu (Huainanzi), and the Regiment of Health (Yangshenglun) in the Qin, Han, Wei, Jin, and Southern and Northern Dynasties all describe regional diseases such as goiter (endemic goiter) and yellowish teeth (dental fluorosis) as being caused by geologic and climatic factors. Zhang (miasma), first mentioned in the Han Dynasty, was considered related to the summer heat and dampness particular to the geographical environment of the south. Zhang was further associated with malaria in the Jin Dynasty. General Treatise on the Etiology and Symptomology of Diseases (Zhubingyuanhou Lun), in the Sui Dynasty, held that as a type of poisonous gas, Zhang was the predisposing cause of malaria, seasonal disease, and barbiers, among other conditions. General Guide (Zhinan Zonglun), in the Southern Song Dynasty, regarded Zhang malaria as a separate disease. Healthy Prescription in the Southern Wuling District (Lingnan Weisheng Fang), in the late Song and early Yuan Dynasties, explicitly put forward the concepts of cold Zhang, hot Zhang, and lockjaw Zhang. Guidelines for Treatment of Zhang Malaria (Zhangnue Zhinan), in the Ming Dynasty, maintained that cold Zhang was equivalent to malaria, while hot Zhang and lockjaw Zhang were equivalent to cold damage, the latter of which can be treated by prescriptions for cold damage. Records on Zhang gas and Zhang disease decreased during the Ming and Qing Dynasties.

It is assured that alfalfa (Medicago sativa L.) was introduced in Han dynasty. There are cognitive differences on whether Zhang Qian introduced alfalfa. Based on the previous studies, research inductive method was used. The relationship between Zhang Qian and alfalfa introduction was analyzed from the motivation, experience and influence of Zhang Qian to the Western Regions and the image generation of Zhang Qian brought back alfalfa’s seeds. Till to now, there are four opinions about Zhang Qian introducing Alfalfa seeds, including : (1) Zhang Qian introduced alfalfa seeds;(2) Zhang Qian did not introduce alfalfa seeds;(3) the information of Zhang Qian transferring alfalfa;(4)for commemoration Zhang Qian to the Western Regions. Although there are not direct historical materials to support Zhang Qian brought alfalfa seed to Han dynasty, it believes and confirms that the introducing of alfalfa is inextricably interwoven with Zhang Qian’s western travel. Zhangqian brought relative information from western regions during the introduction, which was the basis of non-native theory, and after that, Chinese began to plant alfalfa in Han dynasty., According to historical literatures, it is clear that the Chinese diplomat brought alfalfa seeds back to China. Alfalfa, as the favorite forage to Ferghana horse, have been already planted in Dawan in Han dynasty. Despite the debate, Zhangqian played an important pioneering role in introducing alfalfa.

Diet-derived microRNAs: unicorn or silver bullet?

Science.gov (United States)

Witwer, Kenneth W; Zhang, Chen-Yu

2017-01-01

In ancient lore, a bullet cast from silver is the only effective weapon against monsters. The uptake of active diet-derived microRNAs (miRNAs) in consumers may be the silver bullet long sought after in nutrition and oral therapeutics. However, the majority of scientists consider the transfer and regulation of consumer's gene activity by these diet-derived miRNAs to be a fantasy akin to spotting a unicorn. Nevertheless, groups like Dr. Chen-Yu Zhang's lab in Nanjing University have stockpiled breathtaking amounts of data to shoot down these naysayers. Meanwhile, Dr. Ken Witwer at John Hopkins has steadfastly cautioned the field to beware of fallacies caused by contamination, technical artifacts, and confirmation bias. Here, Dr. Witwer and Dr. Zhang share their realities of dietary miRNAs by answering five questions related to this controversial field.

Directed polymers versus directed percolation

Science.gov (United States)

Halpin-Healy, Timothy

1998-10-01

Universality plays a central role within the rubric of modern statistical mechanics, wherein an insightful continuum formulation rises above irrelevant microscopic details, capturing essential scaling behaviors. Nevertheless, occasions do arise where the lattice or another discrete aspect can constitute a formidable legacy. Directed polymers in random media, along with its close sibling, directed percolation, provide an intriguing case in point. Indeed, the deep blood relation between these two models may have sabotaged past efforts to fully characterize the Kardar-Parisi-Zhang universality class, to which the directed polymer belongs.

CNTs cause immunologic dysfunction and limit the application of CNTs in biomedicine. The immunological responses induced by pristine multi-walled carbon nanotubes (p-MWCNTs and PEGylated multi-walled carbon nanotubes (MWCNTs-PEG on BALB/c mice via an intravenous administration were investigated. The results reflect that the p-MWCNTs induced significant increases in spleen, thymus, and lung weight. Mice treated with p-MWCNTs showed altered lymphocyte populations (CD3+, CD4+, CD8+, and CD19+ in peripheral blood and increased serum IgM and IgG levels, and splenic macrophage ultrastructure indicated mitochondria swelling. p-MWCNTs inhibited humoral and cellular immunity function and were associated with decreased immune responses against sheep erythrocytes and serum hemolysis level. Natural killer (NK activity was not modified by two types of MWCNTs. In comparison with two types of MWCNTs, for a same dose, p-MWCNTs caused higher levels of inflammation and immunosuppression than MWCNTs-PEG. The results of immunological function suggested that after intravenous administration with p-MWCNTs caused more damage to systemic immunity than MWCNTs- PEG. Here, we demonstrated that a surface functional modification on MWCNTs reduces

The results of antifungal tests against eight human pathogenic fungi in vitro showed that all the compounds exhibited moderate-to-excellent activities. Molecular docking between 8d and the active site of Candida albicans CYP51 was provided based on the computational docking results. The triazole interacts with the iron of the heme group. The difluorophenyl group is located in the S3 subsite and its fluorine atom (2-F can form H-bonds with Gly307. The side chain is oriented into the S4 subsite and formed hydrophobic and van der Waals interactions with the amino residues. Moreover, the phenyl group in the side chain interacts with the phenol group of Phe380 through the formation of π–π face-to-edge interactions.Keywords: synthesis, CYP51, molecular docking, azole agents

Vertical profiles of atmospheric fluorescent aerosols observed by a mutil-channel lidar spectrometer system

Zhongwei Huang1*, Jianping Huang1, Tian Zhou1, Nobuo Sugimoto2, Jianrong Bi1 and Jinsen Shi11Key Laboratory for Semi-Arid Climate Change of the Ministry of Education, College of Atmospheric Sciences, Lanzhou University, Lanzhou, China. 2Atmospheric Environment Division, National Institutes for Environmental Studies, Tsukuba, Japan Email: huangzhongwei@lzu.edu.cn Abstract Atmospheric aerosols have a significant impact on regional and globe climate. The challenge in quantifying aerosol direct radiative forcing and aerosol-cloud interactions arises from large spatial and temporal heterogeneity of aerosol concentrations, compositions, sizes, shape and optical properties (IPCC, 2007). Lidar offers some remarkable advantages for determining the vertical structure of atmospheric aerosols and their related optical properties. To investigate the characterization of atmospheric aerosols (especially bioaerosols) with high spatial and temporal resolution, we developed a Raman/fluorescence/polarization lidar system employed a multi-channel spectrometer, with capabilities of providing measurements of Raman scattering and laser-induced fluorescence excitation at 355 nm from atmospheric aerosols. Meanwhile, the lidar system operated polarization measurements both at 355nm and 532nm wavelengths, aiming to obtain more information of aerosols. It employs a high power pulsed laser and a received telescope with 350mm diameter. The receiver could simultaneously detect a wide fluorescent spectrum about 178 nm with spectral resolution 5.7 nm, mainly including an F/3.7 Crossed Czerny-Turner spectrograph, a grating (1200 gr/mm) and a PMT array with 32 photocathode elements. Vertical structure of fluorescent aerosols in the atmosphere was observed by the developed lidar system at four sites across northwest China, during 2014 spring field observation that conducted by Lanzhou University. It has been proved that the developed lidar could detect the fluorescent aerosols with high temporal and

However, the role of genetic polymorphisms in ADRB2 on COPD has not been evaluated yet. Methods: In this study, SNaPshot genotyping, luciferase assay, chromatin immunoprecipitation and real-time polymerase chain reaction were adopted to investigate the association between ADRB2 genetic polymorphisms and COPD, comprehensively. Results: One single nucleotide polymorphism (rs12654778, located upstream of ADRB2, showed a significant association with COPD by the logistic regression analysis after adjusting for age, sex and smoking history (p=0.04 in 200 COPD patients and 222 controls from southwest Chinese population. Furthermore, the luciferase assay indicated that rs12654778-A allele reduced the relative promoter activity by ~26% compared with rs12654778-G allele (p=0.0034. The chromatin immunoprecipitation analysis demonstrated that rs12654778 modulated the binding affinity of transcription factor neurofibromin 1.

Sheet universes and the shapes of Friedmann universes

International Nuclear Information System (INIS)

Lynden-Bell, D.; Redmount, I.H.

1989-01-01

Unless Ω>1,the Big Bang did not start from a point. Consideration shows sheet universes in which matter is confined to a homogeneous universe. Sheet universes and the corresponding embeddings of FRW universes into Minkowski space are drawn. Their initial singularities are shown to be point-like for the 'closed' case, line-like for the 'flat' (Ω=1) case and surface-like for the 'open' case. In contrast to the cross-sections at constant comoving proper time, typical spacelike cross-sections of the 'flat' universes are closed and encounter their extensive singularities. All cross-sections of the 'closed' universe are closed and only very special cross-sections encounter the point singularities at the Big Bang or the Big Crunch. (author)

Persistent developmental stuttering (PDS may occur in adults. Reports of the surgical management of PDS are limited. Here we present the case of a 28-year-old man who had had PDS since the age of 7 years, was diagnosed with depression and anxiety disorder at the age of 24 years, and had physical concomitants. He underwent a bilateral anterior capsulotomy 4 years after the diagnosis. Over one year of follow-up, his physical concomitants resolved, and significant improvements in his psychiatric disorders and PDS were observed. To the best of our knowledge, this is the first report of simultaneous improvement in a patient's PDS and psychiatric disorder after a bilateral anterior capsulotomy.Keywords: persistent developmental stuttering, psychiatric disorders, anterior capsulotomy

Between universalism and regionalism: universal systematics from imperial Japan.

Science.gov (United States)

Lee, Jung

2015-12-01

Historiographic discussions of the universality and regionality of science have to date focused on European cases for making regional science universal. This paper presents a new perspective by moving beyond European origins and illuminating a non-European scientist's engagement with the universality and regionality of science. It will examine the case of the Japanese botanist Nakai Takenoshin (1882-1952), an internationally recognized authority on Korean flora based at Tokyo Imperial University. Serving on the International Committee on Botanical Nomenclature in 1926, Nakai endorsed and acted upon European claims of universal science, whilst simultaneously unsettling them with his regionally shaped systematics. Eventually he came to promote his own systematics, built regionally on Korean flora, as the new universal. By analysing his shifting claims in relation to those of other European and non-European botanists, this paper makes two arguments. First, universalism and regionalism were not contradictory foundations of scientific practice but useful tools used by this non-European botanist in maintaining his scientific authority as a representative Japanese systematist. Second, his claims to universality and regionalism were both imperially charged. An imperially monopolized study of Korean plants left a regional imprint on Nakai's systematics. In order to maintain his scientific authority beyond its region of origin he had to assert either the expanding regionalism of 'East Asia' or universalism.

Universe symmetries

The sky uniformity can be noticed in studying the repartition of objects far enough. The sky isotropy description uses space rotations. The group theory elements will allow to give a meaning at the same time precise and general to the word a ''symmetry''. Universe models are reviewed, which must have both of the following qualities: - conformity with the physic known laws; - rigorous symmetry following one of the permitted groups. Each of the models foresees that universe evolution obeys an evolution equation. Expansion and big-bang theory are recalled. Is universe an open or closed space. Universe is also electrically neutral. That leads to a work hypothesis: the existing matter is not given data of universe but it appeared by evolution from nothing. Problem of matter and antimatter is then raised up together with its place in universe [fr

This study developed epidermal growth factor receptor (EGFR antibody-directed polydopamine-coated Fe3O4 nanoparticles (Fe3O4@PDA NPs for magnetic resonance imaging and antitumor chemo-photothermal therapy. The synthesized Fe3O4@PDA-PEG-EGFR-DOX NPs revealed high storage capacity for doxorubicin (DOX and high photothermal conversion efficiency. The cell viability assay of Fe3O4@PDA-PEG-EGFR NPs indicated that Fe3O4@PDA-PEG-EGFR NPs had no cell cytotoxicity. However, Fe3O4@PDA-PEG-EGFR-DOX NPs could significantly decrease cell viability (~5% of remaining cell viability because of both photothermal ablation and near-infrared light-triggered DOX release. Meanwhile, the EGFR-targeted Fe3O4@PDA-PEG-EGFR-DOX NPs significantly inhibited the growth of tumors, showing a prominent in vivo synergistic antitumor effect. This study demonstrated the potential of using Fe3O4@PDA NPs for combined cancer chemo-photothermal therapy with increased efficacy.

New Jurassic tettigarctid cicadas from China with a novel example of disruptive coloration

Directory of Open Access Journals (Sweden)

Jun Chen

2016-12-01

Full Text Available Tettigarctidae is the most primitive family of Cicadoidea, with only two relict species. Although they are relatively well known from Eurasia, Australia, Africa, and South America, their Mesozoic examples are typically preserved only as isolated forewings. Herein, a new genus Sanmai Chen, Zhang, and B. Wang with three new species (Sanmai kongi Chen, Zhang, and B. Wang, S. mengi Chen, Zhang, and B. Wang, and S. xuni Chen, Zhang, and B. Wang are described based on fossil specimens from the Middle–Upper Jurassic of northeastern China, with well-preserved body structures, forewing and hindwing venations, making it the hitherto best known extinct tettigarctid taxon. The new genus, provisionally assigned to the tribe Turutanoviini, provides some new information about the evolution and palaeobiogeography of Mesozoic Tettigarctidae. The genus Paraprosbole is synonymized with Shuraboprosbole. In addition, the coloration pattern of forewing, prominent on some specimens of Sanmai kongi Chen, Zhang, and B. Wang sp. nov. and Sanmai xuni Chen, Zhang, and B. Wang sp. nov., represents a novel example of disruptive coloration in Tettigarctidae, which can effectively break up the body outline as well as surface, and so likely enabled these cicadas to reduce the detectability of potential predators.

Towards a University of the Common: Reimagining the University in Order to Abolish It with the Really Open University

Directory of Open Access Journals (Sweden)

Andre Pusey

2017-07-01

Full Text Available The autumn of 2010, in the UK, was characterised by a series of protests against the proposed tripling of university tuition fees and the removal of the Education Maintenance Allowance (EMA. These protests were set within a broader international background of contestation around universities and higher education reforms. This article focuses on the activities of a group, which emerged within this context, called the Really Open University (ROU, and its efforts to engender a reimagining of the university. Specifically, this article argues that the activities of the ROU were attempts to create new, radical imaginaries of the university and were linked to broader efforts to re-conceptualise knowledge production and pedagogy. The central point is that ultimately the ROU’s invitation to ‘reimagine the university’ was a provocation to abolish the university in its capitalist form, through a process of reimagining the university, exodus from the university machine and creation of a university of the common.

A lightweight universe?

Science.gov (United States)

Bahcall, Neta A.; Fan, Xiaohui

1998-01-01

How much matter is there in the universe? Does the universe have the critical density needed to stop its expansion, or is the universe underweight and destined to expand forever? We show that several independent measures, especially those utilizing the largest bound systems known—clusters of galaxies—all indicate that the mass-density of the universe is insufficient to halt the expansion. A promising new method, the evolution of the number density of clusters with time, provides the most powerful indication so far that the universe has a subcritical density. We show that different techniques reveal a consistent picture of a lightweight universe with only ∼20–30% of the critical density. Thus, the universe may expand forever. PMID:9600898

The Alien University

- they are alien. The conditions of universities today is not one of crisis and upheaval, as with the postmodern universities, it is one of night travel and exile. The alien university leaves behind the epistemological skirmishes of the postmodern university with all its rhetoric and knowledge activism. Thinking...... in the alien university is a move into a whirlpool of nothingness, a “nocturnal space”, where “[d]arkness fills it like a content; it is full, but full of the nothingness of everything.” (Levinas, 2001, p.53). In the alien university thinking is not situated, and instead of rhizomes, and assemblages of thought......, there is merely an imposing and nightly “swarming of points.” (ibid.). There is no place for the alien university, and exactly this exile of thought makes possible the move beyond postmodernism and the mentality of political crisis. The alien university is not in the future as such, but it is not entirely...

Universics: a Theory of Universes of Discourse for Metamathematics and Foundations

Directory of Open Access Journals (Sweden)

Ioachim Drugus

2016-04-01

Full Text Available A new type of structures called ``universes'' is introduced to subsume the ``von Neumann universe'', ``Grothendieck universes'' and ``universes of discourse'' of various theories. Theories are also treated as universes, ``universes of ideas'', where ``idea" is a common term for assertions and terms. A dualism between induction and deduction and their treatment on a common basis is provided. The described approach referenced as ``universics'' is expected to be useful for metamathematical analysis and to serve as a foundation for mathematics. As a motivation for this research served the Harvey Friedman's desideratum to develop a foundational theory based on ``induction construction'', possibly comprising set theory. This desideratum emerged due to ``foundational incompleteness'' of set theory. The main results of this paper are an explication of the notion ``foundational completeness'', and a generalization of well-founded-ness.

Competitive universities need to internationalize learning: Perspectives from three European universities

Directory of Open Access Journals (Sweden)

Ana Maria Lara

2009-07-01

Full Text Available The process of restructuring European universities in order to harmonize their educational systems is rapidly approaching a key milestone as 2010 looms large on the horizon. This paper describes an approach to the European Higher Education Area (EHEA based on a real case study of students that belong to five European Universities (University of Burgos, Technical University of Valencia, University of Valladolid, University of Basque Country and University of Applied Sciences Cologne. The objective of this paper is two-fold: on the one hand, to analyze from the student’s point of view how they value the restructuring of teaching as a result of the Bologna process and what are the implications for students with regards to both their academic qualifications and their future incorporation into the labour market; and, on the other hand, to deduce from the results obtained recommendations which may help to guide teachers towards successful internationalization and collaboration between interuniversity networks, as well as achieving greater standards of quality within university teaching. Only this would permit an environment in which students are capable of developing the necessary competences, and put into practice learning outcomes. The results show that students value communication, innovative proposals and cooperation between universities; the internationalization of knowledge between universities has been positively accepted and this has motivated research to place a stronger focus on this aspect; it impacts strongly on scientific productivity, improves the quality of education offered by the teaching staff, and leads to greater student mobility. This strategy is intrinsically linked to learning from local experiences shared by members of the same university as well as from more global experiences made available through inter-university networks. It implies being willing to listen, to communicate, to engage in dialogue and means that we must

One of the strategies for the prevention of the obesity is the identification of critical periods of gain weight. Some studies confirm gain weight during the university period. The purpose of the present study was to determine the changes in the body weight of the university students in Navarre. Prospective cohort study. Public University of Navarre and the University of Navarre, in Pamplona. Study examined weight change among 452 students attending at university in Pamplona, during first and third course. Four hundred and fifty two students completed the questionnaire. Weight and height were measures and body mass index was calculated. The mean body weight increased 0,600 kg, 1,8 kg for males and no change in body weight was observed in female. 44,7 % of students gained weight (60,8 % of men and 36,8 % of women), and the gain weight was of 3,4 kg. University years are a critical factor for the gain weight, particularly males. Consideration of this, is necessary the development of effective weight gain prevention strategies during the university. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

University Technology Transfer

Directory of Open Access Journals (Sweden)

Mike Cox

2004-09-01

Full Text Available This article describes the experiences and general observations of the author at Heriot-Watt University and concerns the transfer of university technology for the purposes of commercialisation. Full commercial exploitation of a university invention generally requires transferring that technology into the industrial arena, usually either by formation of a new company or licensing into an existing company. Commercialisation activities need to be carried out in unison with the prime activities of the university of research and teaching. Responsibility for commercialising university inventions generally rests with a specific group within the university, typically referred to as the technology transfer group. Each technology transfer should be considered individually and appropriate arrangements made for that particular invention. In general, this transfer process involves four stages: identification, evaluation, protection and exploitation. Considerations under these general headings are outlined from a university viewpoint. A phased approach is generally preferred where possible for the evaluation, protection and exploitation of an invention to balance risk with potential reward. Evaluation of the potential opportunity for a university invention involves essentially the same considerations as for an industrial invention. However, there are a range of commercial exploitation routes and potential deals so that only general guidelines can be given. Naturally, the final deal achieved is that which can be negotiated. The potential rewards for the university and inventor are both financial (via licensing income and equity realisation and non-financial.

That is, the ideal gas equation of state is suitable for the Singular point and the universe. Maybe someone consider that, there is no vessel can accommodate radiation, it is because the Ordinary container is too small to accommodate, if the radius of your container is the distance that Light through an hour, would you still think it can't accommodates radiation? Modern scientific determinate that the radius of the universe now is about 1027 m, assuming that the universe is a sphere whose volume is approximately: V = 4.19 × 1081 cubic meters, the temperature radiation of the universe (cosmic microwave background radiation temperature of the universe, should be the closest the average temperature of the universe) T = 3.15k, radiation pressure P = 5 × 10-6 N / m 2, according to the law of ideal gas state equation, PV / T = constant = 6 × 1075, the value of this constant is the universe, The singular point should also equal to the constant Author: hanyongquan

The inflationary universe

According to the inflationary universe scenario the universe in the very early stages of its evolution was exponentially expanding in the unstable vacuum-like state. At the end of the exponential expansion the energy of the unstable vacuum transforms into the energy of hot dense matter. Recently it was realised that the exponential expansion of the universe naturally occurs in a wide class of realistic theories of elementary particles. The inflationary universe scenario makes it possible to obtain a simple solution to many longstanding cosmological problems and leads to a crucial modification of the standard point of view of the large-scale structure of the universe.

Exactly solvable models of growing interfaces and lattice gases: the Arcetri models, ageing and logarithmic sub-ageing

Science.gov (United States)

Durang, Xavier; Henkel, Malte

2017-12-01

Motivated by an analogy with the spherical model of a ferromagnet, the three Arcetri models are defined. They present new universality classes, either for the growth of interfaces, or else for lattice gases. They are distinct from the common Edwards-Wilkinson and Kardar-Parisi-Zhang universality classes. Their non-equilibrium evolution can be studied by the exact computation of their two-time correlators and responses. In both interpretations, the first model has a critical point in any dimension and shows simple ageing at and below criticality. The exact universal exponents are found. The second and third model are solved at zero temperature, in one dimension, where both show logarithmic sub-ageing, of which several distinct types are identified. Physically, the second model describes a lattice gas and the third model describes interface growth. A clear physical picture on the subsequent time and length scales of the sub-ageing process emerges.

However, low solubility has limited its clinical applications. Preparation of drugs in the form of nanosuspensions is an extensively utilized protocol. In this study, we investigated the anticancer activity of oridonin and oridonin nanosuspension on human pancreatic carcinoma PANC-1 cells. 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide assay was performed to investigate the effect of oridonin on cell growth. Propidium iodide and Hoechst 33342 staining were used to detect morphologic changes. The percentage of apoptosis and cell cycle progression was determined by flow cytometric method staining with propidium iodide. Annexin V-fluorescein isothiocyanate (FITC/PI staining was used to evaluate cell apoptosis by flow cytometry. Caspase-3 activity was measured by spectrophotometry. The apoptotic and cell cycle protein expression were determined by Western blot analysis. Both oridonin and oridonin nanosuspension induced apoptosis and G2/M phase cell cycle arrest, and the latter had a more significant cytotoxic effect. The ratio of Bcl-2/Bax protein expression was decreased and caspase-3 activity was stimulated. The expression of cyclin B1 and p-cdc2 (T161 was suppressed. Our results showed that oridonin nanosuspension was more effective than free oridonin on G2/M cell cycle arrest and apoptosis in the human pancreatic cancer PANC-1 cell line.Keywords: cyclin B1, cdc2, caspase-3, Bcl-2, Bax

Collaboration Between Universities: An effective way of sustaining community-university partnerships?

Directory of Open Access Journals (Sweden)

Jonathan Pratt

2011-11-01

Full Text Available This article highlights some of the opportunities and challenges that collaboration between higher education institutions (HEIs can bring to the development of sustainable community-university partnerships. In particular, it explores the potential for universities to collaborate on building effective engagement mechanisms (such as helpdesks, ‘hub and spoke’ contact models, and research groups to review ideas for activities that will support an ongoing flow of new projects and partnerships over time. It draws on evidence gathered from the evaluation and coordination of the South East Coastal Communities (SECC program, an almost unique experiment in collaboration between English universities. In an ‘age of austerity’, opportunities to reduce costs without damaging core services are of particular interest to public funding bodies. The article suggests that collaboration between universities may be an efficient and effective way of engaging with local communities, but that it is not cost-free, and high-level strategic buy-in within HEIs is required if community-university partnerships are to thrive in the current higher education funding environment. The article also suggests that there may be a geographic dimension to effective collaboration between universities in both community-university partnership work and the mechanisms that support community engagement. Inter-university collaboration across the whole region covered by the SECC program has been much weaker than collaboration at a subregional level and within ‘city-regions’ in particular. This raises a key question: does the natural geography for effective collaboration between universities need to reflect, at least in part, the geographies of communities themselves, in terms of lived experiences and/or community representation? Such a debate has interesting and timely parallels in the United Kingdom, where the new coalition government is bringing about a fundamental shift in the

Previous studies have suggested that aspirin has the potential to promote bone regeneration. The purpose of this study was to prepare a local drug delivery system with aspirin-loaded chitosan nanoparticles (ACS contained in an asymmetric collagen-chitosan membrane (CCM. Methods: In this study, the ACS were fabricated using different concentrations of aspirin (5 mg, 25 mg, 50 mg, and 75 mg. The drug release behavior of ACS was studied. Transmission electron microscopy (TEM and scanning electron microscopy (SEM were used to examine the micromorphology of ACS and aspirin-loaded chitosan nanoparticles contained in chitosan-collagen membranes (ACS-CCM. In vitro bone mesenchymal stem cells (BMSCs were cultured and critical-sized cranial defects on Sprague-Dawley rats were made to evaluate the effect of the ACS-CCM on bone regeneration.Results: Drug release behavior results of ACS showed that the nanoparticles fabricated in this study could successfully sustain the release of the drug. TEM showed the morphology of the nanoparticles. SEM images indicated that the asymmetric membrane comprised a loose collagen layer and a dense chitosan layer. In vitro studies showed that ACS-CCM could promote the proliferation of BMSCs, and that the degree of differentiated BMSCs seeded on CCMs containing 50 mg of ACS was higher than that of other membranes. Micro-computed tomography showed that 50 mg of ACS-CCM resulted in enhanced bone regeneration compared with the control group.Conclusion: This

The Spanish Adherencia Terapéutica en la Esquizofrenia (ADHES survey was developed to determine the scope and causes of medication nonadherence in schizophrenia.Methods: The 20-question ADHES survey was distributed to 19,370 psychiatrists in 13 Asia–Pacific countries in January–April 2012, to ascertain psychiatrists' perceptions of antipsychotic medication adherence levels among their schizophrenia patients, reasons for partial/nonadherence, their preferred methods of assessing adherence, and strategies to improve adherence. Responses are reported as mean and range across countries.Results: Four thousand, six hundred sixty one psychiatrists (24% of recipients completed the survey (highest contributors: People's Republic of China, 1854; India, 1616. Psychiatrists perceived that 56% (range, 30%-71% of schizophrenia patients were non- or partially adherent to medication.

The rotating universe

International Nuclear Information System (INIS)

Ruben, G.; Treder, H.J.

1987-01-01

For a long time the question whether the universe rotates or not is discussed. Aspects of Huygens, Newton, Mach and other important historical scientists in this field are reported. The investigations of the mathematician Kurt Groedel in order to prove the rotation of the universe are illustrated. Kurt Groedel has shown that Einstein's gravitational equations of general relativity theory and the cosmological postulate of global homogeneity of cosmic matter (that is the Copernical principle) are not contradictionary to a rotating universe. Abberation measurements, position determination by means of radiointerferometry and methods for the determination of the rotation of the universe from the isotropy of the background radiation are presented. From these experiments it can be concluded that the universe seems not to rotate as already Einstein expected

CHINA‘S RADIO AND TV UNIVERSITIES AND THE BRITISH OPEN UNIVERSITY: A Comparative Study

The task is impossible because the two entities to be compared are essentially disparate. The British Open University (OUUK is a single university set up at Milton Keynes in the United Kingdom by Royal Charter. China‘s Radio and TV universities, known as the Dianda system, is a network of 45 open universities set up all over China. The essence of the success of the British Open University was its creation as a full university, offering its own university degrees on the same level as all the other universities in the country. The Dianda institutions were set up in what Wei calls the ‗adult higher education sector‘ in China, offering what Wei calls sub-degrees and always regarded as inferior both to the great Chinese universities (Beijing University, Qinghua University, Fudan

Mathematics is studied in universities by a large number of students. At the same time it is a field of research for a (smaller) number of university teachers. What relations, if any, exist between university research and teaching of mathematics? Can research “support” teaching? What research...... and what teaching? In this presentation we propose a theoretical framework to study these questions more precisely, based on the anthropological theory of didactics. As a main application, the links between the practices of mathematical research and university mathematics teaching are examined...

Therefore, we performed a meta-analysis to derive a more accurate estimation of this relationship. Methods: A literature search of PubMed, Embase, Web of Science databases until October 1, 2016, was conducted. Crude odds ratios (ORs with 95% confidence intervals (CIs were calculated to assess the strength of this association. Results: Eighteen case-control studies, with a total of 3,317 prostate cancer patients and 8,324 controls, were included. Results showed that both PvuII and XbaI polymorphisms were significantly associated with a higher prostate cancer risk in overall populations. To derive a more accurate estimation, subgroup analysis stratified by ethnicity revealed that this relationship existed only in Caucasians, but not in Asians. Furthermore, PvuII polymorphism was significantly associated with high Gleason grade (Gleason score ≥7 cancers. Conclusion: The current meta-analysis demonstrates that ERα PvuII and XbaI polymorphisms are associated with a higher prostate cancer risk in Caucasians, but not in Asians, and PvuII polymorphism is significantly associated with high Gleason grade tumors, indicating the probability of inherited susceptibility to prostate cancer arising from different genomic ERα SNPs

(Re)Discovering University Autonomy

DEFF Research Database (Denmark)

This book challenges traditional approach to university autonomy which is based on four pillars: organisational, financial, human resource, and academic. The main thesis is that a fuller understanding of university autonomy can only be obtained through a more holistic view of the complex inter......-relationships between stakeholders and policies which can reinforce and equally pull in opposite directions. The holistic view is expressed in a model of institutional university autonomy that brings together the traditional basic four pillars of autonomy, and five interfaces: government–university; university......–university staff; academic staff–students; university–business; and university–internationalisation. This model is explored through international case studies that give new insights and reinforce our understanding that the issues relating to institutional university autonomy are complex, interactive and genuinely...

Plasma universe

International Nuclear Information System (INIS)

Alfven, H.

1986-04-01

Traditionally the views in our cosmic environment have been based on observations in the visual octave of the electromagnetic spectrum, during the last half-century supplemented by infrared and radio observations. Space research has opened the full spectrum. Of special importance are the X-ray-gamma-ray regions, in which a number of unexpected phenomena have been discovered. Radiations in these regions are likely to originate mainly from magnetised cosmic plasma. Such a medium may also emit synchrotron radiation which is observable in the radio region. If we try to base a model of the universe on the plasma phenomena mentioned we find that the plasma universe is drastically different from the traditional visual universe. Information about the plasma universe can also be obtained by extrapolation of laboratory experiments and magnetospheric in situ measurements of plasma. This approach is possible because it is likely that the basic properties of plasma are the same everywhere. In order to test the usefulness of the plasma universe model we apply it to cosmogony. Such an approach seems to be rather successful. For example, the complicated structure of the Saturnian C ring can be accounted for. It is possible to reconstruct certain phenomena 4-5 bilions years ago with an accuracy of better than 1 percent

The holographic universe

Talbot, Michael

1991-01-01

'There is evidence to suggest that our world and everything in it - from snowflakes to maple trees to falling stars and spinning electrons - are only ghostly images, projections from a level of reality literally beyond both space and time.' This is the astonishing idea behind the holographic theory of the universe, pioneered by two eminent thinkers: physicist David Bohm, a former protege of Albert Einstein, and quantum physicist Karl Pribram. The holographic theory of the universe encompasses consciousness and reality as we know them, but can also explain such hitherto unexplained phenomena as telepathy, out-of-body experiences and even miraculous healing. In this remarkable book, Michael Talbot reveals the extraordinary depth and power of the holographic theory of the universe, illustrating how it makes sense of the entire range of experiences within our universe - and in other universes beyond our own.

Universities scale like cities.

Directory of Open Access Journals (Sweden)

Anthony F J van Raan

Full Text Available Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law scaling with population size. These nonlinear effects are common to all cities, with similar power law exponents. These findings mean that the larger the city, the more disproportionally they are places of wealth and innovation. Local properties of cities cause a deviation from the expected behavior as predicted by the power law scaling. In this paper we demonstrate that universities show a similar behavior as cities in the distribution of the 'gross university income' in terms of total number of citations over 'size' in terms of total number of publications. Moreover, the power law exponents for university scaling are comparable to those for urban scaling. We find that deviations from the expected behavior can indeed be explained by specific local properties of universities, particularly the field-specific composition of a university, and its quality in terms of field-normalized citation impact. By studying both the set of the 500 largest universities worldwide and a specific subset of these 500 universities--the top-100 European universities--we are also able to distinguish between properties of universities with as well as without selection of one specific local property, the quality of a university in terms of its average field-normalized citation impact. It also reveals an interesting observation concerning the working of a crucial property in networked systems, preferential attachment.

The BVU is supported by the Bavarian Ministry of Higher Education. At present, there are more than 60,000 course enrolments by more than 25,000 Bavarian students per academic year. The BVU provides online-courses with an equivalent of two to six credit points (by ECTS standards which the member universities, all of them traditional brick-and-mortar universities, can integrate into their courses of study. Students of the member universities can attend the courses free of charge. The BVU offers neither complete courses of study nor degrees of its own. The basic and most important principles of the BVU are: Blended learning at the macro level of the course of study, not at the micro-level of the single course, priority given to asynchronous forms of communication; offering courses which are completely online, thus facilitating the import and export of online-courses between all 31 member universities and allowing a maximum of flexibility to the students. The BVU finances the developing as well as the conducting of its courses. This supports teachers in providing tuition to students from other universities.

The isotropic Universe

International Nuclear Information System (INIS)

Raine, D.J.

1981-01-01

This introduction to contemporary ideas in cosmology differs from other books on the 'expanding Universe' in its emphasis on physical cosmology and on the physical basis of the general theory of relativity. It is considered that the remarkable degree of isotropy, rather than the expansion, can be regarded as the central observational feature of the Universe. The various theories and ideas in 'big-bang' cosmology are discussed, providing an insight into current problems. Chapter headings are: quality of matter; expanding Universe; quality of radiation; quantity of matter; general theory of relativity; cosmological models; cosmological tests; matter and radiation; limits of isotropy; why is the Universe isotropic; singularities; evolution of structure.

2003-01-01

As basic policy, NASA believes that colleges and universities should be encouraged to participate in the nation's space and aeronautics program to the maximum extent practicable. Indeed, universities are considered as partners with government and industry in the nation's aerospace program. NASA's objective is to have them bring their scientific, engineering, and social research competence to bear on aerospace problems and on the broader social, economic, and international implications of NASA's technical and scientific programs. It is expected that, in so doing, universities will strengthen both their research and their educational capabilities to contribute more effectively to the national well being. This annual report is one means of documenting the NASA-university relationship, frequently denoted, collectively, as NASA's University Program. This report is consistent with agency accounting records, as the data is obtained from NASA's Financial and Contractual Status (FACS) System, operated by the Financial Management Division and the Procurement Office. However, in accordance with interagency agreements, the orientation differs from that required for financial or procurement purposes. Any apparent discrepancies between this report and other NASA procurement or financial reports stem from the selection criteria for the data. This report was prepared by the Office of Education/N.

From Eminent Men to Excellent Universities: University Rankings as Calculative Devices.

Science.gov (United States)

Hammarfelt, Björn; de Rijcke, Sarah; Wouters, Paul

2017-01-01

Global university rankings have become increasingly important 'calculative devices' for assessing the 'quality' of higher education and research. Their ability to make characteristics of universities 'calculable' is here exemplified by the first proper university ranking ever, produced as early as 1910 by the American psychologist James McKeen Cattell. Our paper links the epistemological rationales behind the construction of this ranking to the sociopolitical context in which Cattell operated: an era in which psychology became institutionalized against the backdrop of the eugenics movement, and in which statistics of science became used to counter a perceived decline in 'great men.' Over time, however, the 'eminent man,' shaped foremost by heredity and upbringing, came to be replaced by the excellent university as the emblematic symbol of scientific and intellectual strength. We also show that Cattell's ranking was generative of new forms of the social, traces of which can still be found today in the enactment of 'excellence' in global university rankings.

The Universe of Fluctuations The Architecture of Spacetime and the Universe

CERN Document Server

Sidharth, B G

2005-01-01

The Universe of Fluctuations: The Architecture of Spacetime and the Universe is a path-breaking work which proposes solutions to the impasse and crisis facing fundamental physics and cosmology. It describes a cosmological model based on fuzzy spacetime that has correctly predicted a dark-energy-driven acceleration of our expanding universe - with a small cosmological constant - at a time when the popular belief was quite the contrary. It describes how the Universe is made up of an underpinning of Planck oscillators in a Quantum Vacuum. This leads to, amongst other things, a characterization of gravitation as being distributional over the entire Universe, thereby providing an answer to a puzzle brought to light by Weinberg years ago and since overlooked. There is also a simple formula for the mass spectrum of all known elementary particles, based on QCD dynamics. Many other interesting ramifications and experimental tests for the future are also discussed. This apart, there is a brief survey of some of the exi...

Inflation in the Universe

The problems of explaining the observed isotropy, homogeneity, flatness and specific entropy of the Universe are discussed in the context of an inflationary Universe which has recently been suggested. It is shown that the isotropy cannot be ignored as a Universe with a large amount of anisotropy will not undergo the inflationary phase. A Universe with only moderate anistropy will undergo inflation and will be rapidly isotropized. (U.K.)

An open-label, two-period comparative study was conducted in 12 healthy women volunteers. A single dose of the study combined EE/GE transdermal contraceptive patch and oral tablet (Milunet® were administered. Blood samples at different time points after dose were collected, and concentrations were analyzed. A reliable, highly sensitive and accurate high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC/MS/MS assay method was developed in this study to determine the plasma concentrations of EE and GSD. Compared to the tablet, the study patch had a significantly decreased maximum plasma concentration (Cmax, extended time to reach the Cmax and half-life, as well as increased clearance and apparent volume of distribution. The half-lives of EE and GSD of the patch were 3.3 and 2.2 times, respectively, than the half-life of the tablet. The areas under the plasma concentration–time curve (AUCs of EE and GSD of the patch were 8.0 and 16.2 times, respectively, than the AUC of the tablet. No severe adverse event was observed during the whole study, and the general safety was acceptable. In conclusion, compared to the oral tablet Milunet, the study contraceptive patch was well tolerated and showed potent drug exposure, significant extended half-life and stable drug concentrations. Keywords: pharmacokinetics, safety, ethinylestradiol/gestodene, transdermal contraceptive patch

School education had gradually become the mainstream of medical education at the turn of the Qing Dynasty and Republican period. In Tianjin, there were western medical education, including the Peiyang Medical College, Army Medical College, and Lu's Medical School, whereas, there was no traditional medical school at all. To check this defect, two private TCM medical schools, the Learning School of TCM, and the Tianjin TCM Institution were set up by Chen Zedong and Gu Jinren respectively through persistent endeavor. Meanwhile, correspondence school of TCM were established by Zhang Xichun, Wei Jiaqian, and Ma Leshan. Though more TCM schools were planned, including Tianjin Private School of TCM by Lu Zongren and Qian Boquan, North China Professional TCM School by Zhang Yinqi and other colleagues, TCM Professional School by Zhang Dianju and the Tianjin Private Acu-Moxibustion School by Zhang Lihui, etc. All these did make their contributions to the training of TCM talents in modern times.

The Multi-Universe Cosmos. The Origin and Fate of our Universe

Velan, Karel

18 billion yers ago our Universe, one of many in the Cosmos, emerged from a hot, dense fireball of matter and energy created in the 4-dimensional cosmic space-time from virtual particles receiving their rest mass from a powerful primordial radiation field, the missing link to any viable theory of creation. The cloud of elementary particles and radiation collapsed by gravity into a fireball until its trappped thermal radiation caused a titanic explosion that initiated the expansion and evolution of ours universe. As the universe expanded and cooled it spawned galaxies, stars, planets and life. Proven laws of physics, observationsl data and mathematical computations support the new cosmological model which proposes a large number of universes in the cosmos in varying stages of evolution

Tuning across Universalities with a Driven Open Condensate

Directory of Open Access Journals (Sweden)

A. Zamora

2017-10-01

Full Text Available Driven-dissipative systems in two dimensions can differ substantially from their equilibrium counterparts. In particular, a dramatic loss of off-diagonal algebraic order and superfluidity has been predicted to occur because of the interplay between coherent dynamics and external drive and dissipation in the thermodynamic limit. We show here that the order adopted by the system can be substantially altered by a simple, experimentally viable tuning of the driving process. More precisely, by considering the long-wavelength phase dynamics of a polariton quantum fluid in the optical parametric oscillator regime, we demonstrate that simply changing the strength of the pumping mechanism in an appropriate parameter range can substantially alter the level of effective spatial anisotropy induced by the driving laser and move the system into distinct scaling regimes. These include (i the classic algebraically ordered superfluid below the Berezinskii-Kosterlitz-Thouless (BKT transition, as in equilibrium; (ii the nonequilibrium, long-wavelength-fluctuation-dominated Kardar-Parisi-Zhang (KPZ phase; and the two associated topological-defect-dominated disordered phases caused by proliferation of (iii entropic BKT vortex-antivortex pairs or (iv repelling vortices in the KPZ phase. Furthermore, by analyzing the renormalization group flow in a finite system, we examine the length scales associated with these phases and assess their observability in current experimental conditions.

Transition from AdS universe to DS universe in the BPP model

International Nuclear Information System (INIS)

Kim, Wontae; Yoon, Myungseok

2007-01-01

It can be shown that in the BPP model the smooth phase transition from the asymptotically decelerated AdS universe to the asymptotically accelerated DS universe is possible by solving the modified semiclassical equations of motion. This transition comes from noncommutative Poisson algebra, which gives the constant curvature scalars asymptotically. The decelerated expansion of the early universe is due to the negative energy density with the negative pressure induced by quantum back reaction, and the accelerated late-time universe comes from the positive energy and the negative pressure which behave like dark energy source in recent cosmological models

The Wider Impacts of Universities: Habermas on Learning Processes and Universities

Directory of Open Access Journals (Sweden)

Jesper Eckhardt Larsen

2013-06-01

Full Text Available The discourse of reform in higher education tends to focus narrowly on employability and the relationship between higher education and the labor market. Universities as research institutions are now considered solely in the dominant discourse of innovation. This way of conceiving universities is inspired by functionalist theory that focuses on the imperatives of a knowledge economy. Taking a departure in the theory of society developed by Jürgen Habermas this paper seeks to provide a theoretical framework for an empirical comparative analysis on the wider societal impact of universities. It is the argument that the wider impacts of higher education and research at universities must be seen in a more complex vision of modern societies. The paper is thus primarily a re-reading of Habermas’ critique of functionalist views of the university and an application of Habermas’ critique on current issues in the debates on higher education. A special discussion will be taken on issues of the self in view of the current tendencies to regard all education from the standpoint of the economic outputs.

The University of Stuttgart's Institut fuer Kernenergetik und Energiesysteme (IKE) and the University of Arizona have had a joint program in which graduate students from the IKE spend 1 yr on the University of Arizona campus. This program started in 1982 largely as the result of an initiative begun by K.H. Hoecker, then director of IKE. Since 1985, Alfred Voss has been director and the program has continued without interruption. Under the program, the Deutscher Akademisher Austauschdienst, a government agency of the Federal Republic of Germany has funded scholarships for students from IKE, which provide support for 1 yr during which they attend the University of Arizona as visiting student scholars and engage in a research project under the direction of one of our faculty, which satisfies a part of the requirements for the Ingenieur-Diplom Fachrichtung Maschinenbau. The students get credit for their research from the University of Stuttgart. The topics have a broad range and include software development, artificial intelligence, radiation transport, and energy management studies

The influence of a polyethylene glycol (PEG coating on the distribution and toxicity of the NGO was also investigated. The results show that NGO is mainly retained in the liver, lung, and spleen. Retention in the lung is partially due to NGO aggregation. The PEG coating reduces the retention of NGO in the liver, lung, and spleen and promotes the clearance of NGO from these organs, but NGO and NGO-PEG are still present after 3 months. The PEG coating effectively reduces the early weight loss caused by NGO and alleviates NGO-induced acute tissue injuries, which can include damage to the liver, lung, and kidney, and chronic hepatic and lung fibrosis.

Cuprous oxide nanoparticles (CONPs can selectively induce apoptosis and suppress the proliferation of tumor cells, showing great potential as a clinical cancer therapy. Treatment with CONPs caused a G1/G0 cell cycle arrest in tumor cells. Furthermore, CONPs enclosed in vesicles entered, or were taken up by mitochondria, which damaged their membranes, thereby inducing apoptosis. CONPs can also produce reactive oxygen species (ROS and initiate lipid peroxidation of the liposomal membrane, thereby regulating many signaling pathways and influencing the vital movements of cells. Our results demonstrate that CONPs have selective cytotoxicity towards tumor cells, and indicate that CONPs might be a potential nanomedicine for cancer therapy.Keywords: nanomedicine, selective cytotoxicity, apoptosis, cell cycle arrest, mitochondrion-targeted nanomaterials

Taiwan Universities: Where to Go?

Yu-Ying Kuo

2016-02-01

Full Text Available The dramatic expansion of Taiwan universities/colleges from about 100 to 160 from the late 1980s has encountered problems due to social and global changes. What should Taiwan universities move toward and how? This research relies on secondary data to explore the issues Taiwan universities currently face—a low birth rate and global competition. The decreasing number of incoming students will result in a lower registration rate and less tuition revenue, which will make some universities struggle to survive. Hence, government policies, proposed by the Ministry of Education, have been implemented to assist Taiwan universities to adjust to external changes. The Innovative Transformation Policy, adopted in 2015, consists of strategies for university–industry cooperation, university mergers, university closures, and a re-shaping of the university paradigm. This policy has begun to be implemented and its initial outcome will be continually evaluated. In accordance with the Innovative Transformation Policy, this study encourages Taiwan universities to improve governance, set prominent unique characteristics of development, and enhance global competitiveness.

Delivery of educational and research services through these university websites including information, interaction, transaction, and Integration were investigated using a checklist. The data were then analyzed by means of descriptive statistics and using SPSS software. Level of educational and research services by websites of the medical universities type I and II was evaluated medium as 1.99 and 1.89, respectively. All the universities gained a mean score of 1 out of 3 in terms of integration of educational and research services. Results of the study indicated that Iranian universities have passed information and interaction stages, but they have not made much progress in transaction and integration stages. Failure to adapt to e-government in Iranian medical universities in which limiting factors such as users' e-literacy, access to the internet and ICT infrastructure are not so crucial as in other organizations, suggest that e-government realization goes beyond technical challenges.

Wikipedia ranking of world universities

Lages, José; Patt, Antoine; Shepelyansky, Dima L.

2016-03-01

We use the directed networks between articles of 24 Wikipedia language editions for producing the wikipedia ranking of world Universities (WRWU) using PageRank, 2DRank and CheiRank algorithms. This approach allows to incorporate various cultural views on world universities using the mathematical statistical analysis independent of cultural preferences. The Wikipedia ranking of top 100 universities provides about 60% overlap with the Shanghai university ranking demonstrating the reliable features of this approach. At the same time WRWU incorporates all knowledge accumulated at 24 Wikipedia editions giving stronger highlights for historically important universities leading to a different estimation of efficiency of world countries in university education. The historical development of university ranking is analyzed during ten centuries of their history.

The accidental universe

International Nuclear Information System (INIS)

Davies, P.C.W.

1982-01-01

Is our universe an accident of nature. The mysterious coincidences underlying the structure and properties of the universe that we inhabit are examined. This is the first book for the non-specialist reader to present in depth the provocative hypothesis that the structure of the physical world is exceedingly contrived in its appearance. A survey is presented of the range of apparently miraculous accidents of nature that have enabled the universe to evolve its familiar structures: atoms, stars, galaxies, and life itself. This book concludes with an investigation of the so-called 'anthropic principle' which postulates that 'miraculous coincidences' are inevitable in any universe containing conscious observers. This thesis of a cosmic biological selection effect will both reassure and enrage readers, the very existence of whom may be related to fine tuning in the laws of physics. (author)

Full Text Available A mutually beneficial relationship has developed over the past 15 years between a regional South Australian branch of the University of the Third Age (U3A and the local university campus. Arising from the initiative of a community member, the group sought assistance from the university, and has now become integrated into campus life. The university has provided a venue for meetings and access to other facilities, and university staff have contributed to the program of classes. The U3A has undoubtedly benefited from these inputs. However, the university has also benefited from these opportunities to engage with the wider community, the presence of willing volunteers to contribute in various ways to university classes and other activities, and favourable word-of-mouth marketing. Beginning with background information on U3A, the local branch and its setting, we reflect on the sustainability of this relationship with the university and the factors that have contributed to this. We draw on our U3A experience and on two qualitative research projects in which U3A members have taken part: projects which have investigated their motivation for participation in U3A classes and activities, and the contributions of U3A to the university and vice versa. Not only has the relationship itself been sustained thus far, it has also contributed to sustaining U3A members in their active involvement in learning and community activities, and has been a significant part of community engagement activities of the campus.

Improving Innovation in University Spin-Offs. The Fostering Role of University and Region

Directory of Open Access Journals (Sweden)

Antonio Prencipe

2016-06-01

Full Text Available University spin-offs (USOs are companies created to commercialize knowledge or technology developed in academia; thus, their major contribution to the knowledge economy is their ability to generate innovation. Following the Resource-Based View of the Firm and the Knowledge Spillover Theory of Entrepreneurship, it was stated that fostering mechanisms at university level and at regional level may positively influence the USOs innovation. Based on a sample of 621 Italian USOs, we show that the positive impact of the university context is more crucial compared with those of the regional context. In particular, the university affiliated business incubators and Science Parks, jointly with the university financial resources, seem to promote the innovation efforts of USOs. These evidences rise the need of a resilient partnership among all the contextual players involved in the spillover processes, mainly at regional level, in order to effectively exploit the potential innovative efforts of the university start-ups.

2017-12-01

Full Text Available The National Higher Education Strategic Plan Beyond 2020 aims at further strengthening Malaysian research universities and envisions that two Malaysian universities will be among the Top 100 world universities. To date there are 5 research universities in Malaysia, namely University of Malaya (UM, Universiti Kebangsaan Malaysia (UKM, Universiti Sains Malaysia (USM, Universiti Putra Malaysia (UPM and Universiti Teknologi Malaysia (UTM being the latest addition. These research universities are required to focus primarily on research and innovation activities, driven by highly competent academics and competitive student admissions. Research universities too are expected to explore their intellectual capacity and become models of Malaysian universities in conducting research activities aimed at knowledge advancement. Apart from this research universities are entrusted to generate their own income and establish holding companies responsible for conducting business ventures through the commercialization of their research products. Quality and quantity of researchers, research and postgraduates are also expected to increase in these research driven institutions. This calls for a visionary university leadership and the application of a new image and organizational principles. Education, training and employment policies too have to be reviewed, to ensure staff have the skills necessary for the development of research activities.

Quantum entanglement of baby universes

Aganagic, Mina; Okuda, Takuya; Ooguri, Hirosi

2007-01-01

We study quantum entanglements of baby universes which appear in non-perturbative corrections to the OSV formula for the entropy of extremal black holes in type IIA string theory compactified on the local Calabi-Yau manifold defined as a rank 2 vector bundle over an arbitrary genus G Riemann surface. This generalizes the result for G=1 in hep-th/0504221. Non-perturbative terms can be organized into a sum over contributions from baby universes, and the total wave-function is their coherent superposition in the third quantized Hilbert space. We find that half of the universes preserve one set of supercharges while the other half preserve a different set, making the total universe stable but non-BPS. The parent universe generates baby universes by brane/anti-brane pair creation, and baby universes are correlated by conservation of non-normalizable D-brane charges under the process. There are no other source of entanglement of baby universes, and all possible states are superposed with the equal weight

There are some mechanism to commercialize the innovations that have been developed by academic scientists in universities, i.e. patenting, licensing, start-up creation, and university-industry partnerships. The start-up creations or university spin-offs (USOs) company is a very special start-up company that is founded by an academic inventor and the university with the aim to commercialize the technological innovation that created by the university. However, it is not always as smooth as expected. The market competitiveness of the USOs obviously has many challenges to be able to compete with the existing companies, analysis need to be done to get the right business step so the business strategy will be efficient. In this article, we discuss a real case study of a university spin-off that owned by Sebelas Maret University for Commercializing Battery Lithium. The aim of our research is twofold: first, to identify the gap in the literature of business strategy formulation between a conventional and USOs. Second, to propose a business strategy formulation for commercializing university-created technology, i.e. battery lithium as core business of a university spin-off as a case study. We conduct surveys, observation and FGD in order to collect the data and information to build the company objective and goals. The analytical tools to generate the solution of business strategy are SWOT analysis, IFE-EFE matrix, and QSPM model so the result will be the most attractive and suitable for the company. The result shows that the case study of USO company is classified on conservative continuous improvement phase so the suitable strategy for this company are product development and business strategy integration.

We examine the antitumor effects of BIBF 1120 on nasopharyngeal carcinoma (NPC in vitro and in vivo. Materials and methods: The effect of BIBF 1120 on NPC cell proliferation was evaluated using the Cell Counting Kit 8 assay. The activities of BIBF 1120 as a single agent and in combination with cisplatin (DDP in NPC tumor xenografts were evaluated by measuring microvessel density and expression of vascular endothelial growth factor signaling. Results: BIBF 1120 exhibited limited inhibition of the growth of three NPC cell lines. Concurrent administration of BIBF 1120 and DDP provided greater antitumor effects compared to that observed with the use of either inhibitor as a single agent in the NPC xenograft model. Microvessel density and expression of vascular endothelial growth factor signaling were significantly reduced. Conclusion: BIBF 1120, either as a single agent or in combination with DDP, demonstrates significant antitumor and antiangiogenic effects in the NPC xenograft model. Our results indicate that BIBF 1120 administered in conjunction with chemotherapy might provide an effective treatment method for NPC. Keywords: BIBF 1120, nasopharyngeal carcinoma, antiangiogenesis, microvessel density

College student bereavement, scholarship, and the university: a call for university engagement.

Science.gov (United States)

Balk, D E

2001-01-01

The prevalence of bereavement among traditional-aged college students should impel universities to assist bereaved students on their campuses. Dealing with bereavement can not only challenge a college student's completing the developmental tasks that our society sets for the later adolescent years, but also imperil the student's remaining in school and graduating. It is in the best interests of the university to develop and implement a variety of effective interventions to assist bereaved students. The author argues that universities are communities devoted to scholarly endeavors and should explicitly incorporate the dimension of compassion and caring. An abbreviated case study is used to illustrate the situations in which one grieving student found herself when she returned to school following the death of her father. A call is made for greater university engagement by forming a university-based bereavement center to coordinate and conduct coherent inquiry that fulfills the scholarly functions of discovery, application, and instruction. Four specific actions for a bereavement center are to train nonbereaved students to provide peer support, to provide structured interventions for college students at risk of bereavement complications, to raise consciousness about bereavement on the university campus, and to conduct research into various bereavement populations and bereavement topics.

2013-03-01

The 12th International Symposium on Multiscale, Multifunctional and Functionally Graded Materials (FGM-2012) was held in Beijing, China, from 22-36 October 2012. This was part of a series of conferences organized every two years endorsed by International Advisory Committee for FGM's, which serves as a forum for scientists, educators, engineers and young students interested in the development of functionally graded materials (FGM). The series continues from the previous international symposium on FGM held in Sendai, Japan (1990), San Francisco, USA (1992), Lausanne, Switzerland (1994), Tsukuba, Japan (1996), Dresden, Germany (1998), Estes Park, USA (2000), Beijing, China (2002), Leuven, Belgium (2004), Hawaii, USA (2006), Sendai, Japan (2008) and Guimaraes, Portugal (2010). Functionally graded materials are non-uniform materials which are designed with embodied continuous spatial variations in composition and microstructure for the specific purpose of adjusting their thermal, structural, mechanical, biological or functional response to specific application conditions. Such multi-phase materials cover a range of space and time scales, and are best understood by means of a comprehensive multiscale, multiphysics approach. These kinds of materials are presently in the forefront of materials research, receiving worldwide attention. They have a broad range of applications including for example, biomedical, biomechanical, automotive, aerospace, mechanical, civil, nuclear, and naval engineering. New applications are continuously being discovered and developed. The objective of the FGM-2012 intends to provide opportunities for exchanging ideas and discussing state-of-the-art theories, techniques and applications in the fields of multiscale, multifunctional and FGM, through invited lectures, oral and poster presentations. FGM-2012 was organized and hosted by University of Science and Technology Beijing, China, together with Tsing-hua University and Wuhan University of

Self-image and Missions of Universities: An Empirical Analysis of Japanese University Executives

Directory of Open Access Journals (Sweden)

Masataka Murasawa

2014-05-01

Full Text Available As universities in Japan gain institutional autonomy in managing internal organizations, independent of governmental control as a result of deregulation and decentralizing reforms, it is becoming increasingly important that the executives and administrators of each institution demonstrate clear and strategic vision and ideas to external stakeholders, in order to maintain financially robust operations and attractiveness of their institutions. This paper considers whether and how the self-image, mission, and vision of universities are perceived and internalized by the management of Japanese universities and empirically examines the determinants of shaping such individual perceptions. The result of our descriptive analysis indicates that the recent government policy to internationalize domestic universities has not shown much progress in the view of university executives in Japan. An increasing emphasis on the roles of serving local needs in research and teaching is rather pursued by these universities. Individual perceptions among Japanese university executives with regard to the missions and functional roles to be played by their institutions are influenced by managerial rank as well as the field of their academic training. A multiple regression analysis reveals that the economy of scale brought out by an expanded undergraduate student enrollment gradually slows down and decelerate executive perceptions, with regard to establishing a globally recognized status in research and teaching. Moreover, Japanese universities with a small proportion of graduate student enrollment, likely opted out from competitions for gaining a greater respect in the global community of higher education between 2005 and 2012. Finally, the management in universities granted with the same amount of external research funds in both studied years responded more passively in 2012 than did in 2005 on the self-assessment of whether having established a status as a global

Age of the universe

The age of the universe is the time that has elapsed since the Big Bang. To calculate the age, the expansion rate of the universe and distance to the galaxies must be determined. Unfortunately, it appears that the expansion rate is not constant but is decelerating. In the 1920's and 30's, Edwin Hubble set out to estimate the age of universe based on the expansion rate and distance to the galaxies. His method is described along with its flaw. Since that time several others have estimated the age of the universe. Their methods as well as results vary. These are discussed in the article. The ages determined from the various methods range from 10 to 20 billion years. There are two independent ways to determine the age of the universe. What they actually do is determine the age of our galaxy which would give a lower limit to the age of the universe. The first method calculates age of globular clusters which yields as age range from 8 to 18 billion years. The second method involves observing the speed at which radioactive substances decay. This also yields and age greater than 10 billion years. It is clear that there is still a lot of work to do before the true age of the universe can be determied

On universality in ergoregion mergers

International Nuclear Information System (INIS)

Elvang, Henriette; Figueras, Pau; Hubeny, Veronika E; Rangamani, Mukund; Horowitz, Gary T

2009-01-01

We study non-dynamical mergers of ergoregions in d + 1-dimensional vacuum gravity. At the merger point, where the ergosurfaces bounding each ergoregion just touch, solutions exhibit universal behavior when there is rotation only in one plane: the angle between the merging ergosurfaces depends only on the symmetries of the solution, not on any other details of the configuration. We show that universality follows from the fact that the relevant component of Einstein's equation reduces to Laplace's equation at the point of merger. Thus ergoregion mergers mimic mergers of Newtonian equipotentials and have similar universal behavior. For solutions with rotation in more than one plane, universality is lost. We demonstrate universality and non-universality in several explicit examples.

Dipolar flow theory of the universe in relation to astronomical observations and universe axis

International Nuclear Information System (INIS)

Mullick, U.P.

1975-01-01

An attempt has been made to establish Dipolar continuous flow theory of the universe through corroborations from astronomical observations of the positions of nebulae made earlier by astronomers. It is shown that the line through groups of nebulae in Nubecula Major in Southern Sky Region 5, passing through Earth points towards the near side pole A of the universe. Also the angles the plane parallel to universe polar plane x-x and passing through Earth, makes with the Milky Way disc is about 70 0 towards universe pole B, and about 110 0 towards nearside universe pole A. It is also shown that the two nebulae M 31 and M 33 and the groups of nebulae in Megallenic clouds, in Nebecula Major are between planes passing through universe equatorial axis y-y and plant Ysub(E)-Ysub(E) passing through Earth and parallel to universe equatorial plane Y-Y. Besides, the huge red star Betelgeux and the great Nebula in Orion in sky Region 9 are also between these two planes. These observations the author claims accord with his Dipolar Theory. (author)

Cultural universals: So what?

Directory of Open Access Journals (Sweden)

M. Elaine Botha

1989-03-01

Full Text Available The search for the elusive "cultural universal s” in a variety of academic disciplines has been motivated b y the spectre of relativism in its diverse guises. The problem of relativism has been thrust upon us inter alia by the inability of our epistemological models to account for social and cultural, moral and cognitive diversity and to provide us with criteria by means of which to judge aberrations like ideologies. Contrary to the general trend I would like to argue that it is not the spectre of relativism in its various guises which necessitates the search for cultural universals, nor is this the only motivation for a Christian to argue in favour of the recognition of cultural universals. Various authors have suggested that such universal structures do exist; that they condition human and societal behaviour and that it would in principle be possible to construct a theory of these structural universals or a "biogrammar" or "geography ” of the universal cultural acquisition device of humankind (cf. Harre,1976, 32; Johnson, 1987: xxxvii ; Tige r and Fox, 1974:17,30. Cross -cu ltural research in both psychology and anthropology has pointed to the existence of such traits, and in recent philosophical discussions Apel and others have pointed to the necessity of recognizing the existence of some sort of " transcendentalia" . These arguments emphasize elements that are common to diverse approaches to the problem of cultural universals. Christian scholars could accept most of these arguments as valid and yet argue in favour of a very specifically modified version of the notion of cultural universals. This essay attempts to develop such a position.

Boundary crossover in semi-infinite non-equilibrium growth processes

International Nuclear Information System (INIS)

Allegra, Nicolas; Fortin, Jean-Yves; Henkel, Malte

2014-01-01

The growth of stochastic interfaces in the vicinity of a boundary and the non-trivial crossover towards the behaviour deep in the bulk are analysed. The causal interactions of the interface with the boundary lead to a roughness larger near to the boundary than deep in the bulk. This is exemplified in the semi-infinite Edwards–Wilkinson model in one dimension, from both its exact solution and numerical simulations, as well as from simulations on the semi-infinite one-dimensional Kardar–Parisi–Zhang model. The non-stationary scaling of interface heights and widths is analysed and a universal scaling form for the local height profile is proposed. (paper)

The university with conditions

Directory of Open Access Journals (Sweden)

José María Ripalda Crespo

2013-03-01

Full Text Available The model of the national university is being substituted by that of the global university. At the same time, new dogmas that appear with economic labels are being imposed. All this is accompanied by important cultural changes. The Spanish university was one of the instances that was taken care of by the post-Francoist regime. Now, this regime feels strong against it, and on the other hand this university – as the whole of the productive structure – requires a reform. It is not expected that this reform will go in the direction of the university having more social presence, but rather more presence of companies. It is neither expected that it will imply more internal democracy, but more discipline. All resistance or alternative has to take into account the new situation and join the still dispersed forces that still have, however, a constitutive capacity.

Possible physical universes

Gordon McCabe

2005-12-01

Full Text Available The purpose of this paper is to discuss the various types of physical universe which could exist according to modern mathematical physics. The paper begins with an introduction that approaches the question from the viewpoint of ontic structural realism. Section 2 takes the case of the 'multiverse' of spatially homogeneous universes, and analyses the famous Collins-Hawking argument, which purports to show that our own universe is a very special member of this collection. Section 3 considers the multiverse of all solutions to the Einstein field equations, and continues the discussion of whether the notions of special and typical can be defined within such a collection.

Titanium Isotopes Provide Clues to Lunar Origin

Science.gov (United States)

Taylor, G. J.

2012-05-01

The idea that the Moon formed as the result of the giant impact of a Mars-sized impactor with the still-growing Earth explains two central facts about the Earth-Moon system: its total angular momentum (Earth's spin and the Moon's orbital motion), and the sizes of the metallic cores of the Earth (large) and Moon (tiny). This gives cosmochemists some confidence in the hypothesis, but they would greatly appreciate additional compositional tests. One undisputed point is the identical abundance of the three oxygen isotopes in Earth and Moon. Junjun Zhang and colleagues at the University of Chicago (USA) and the University of Bern (Switzerland) have added another isotopic system to the cosmochemical testing tool kit, titanium isotopes. They find that the ratio of titanium-50 to titanium-47 is identical in Earth and Moon to within four parts per million. In contrast, other solar system materials, such as carbonaceous chondrites, vary by considerably more than this-- up to 150 times as much. The identical oxygen and titanium isotopic compositions in Earth and Moon are surprising in light of what we think we know about planet formation and formation of the Moon after a giant impact. The variations in oxygen and titanium isotopes among meteorite types suggest that it is unlikely that the Moon-forming giant impactor would have had the same isotopic composition as the Earth. Simulations show that the Moon ends up constructed mostly (40-75%) from the impactor materials. Thus, the Moon ought to have different isotopic composition than does Earth. The isotopes might have exchanged in the complicated, messy proto-lunar disk (as has been suggested for oxygen isotopes), making them the same. However, Zhang and colleagues suggest that this exchange is unlikely for a refractory element like titanium. Could the impact simulations be greatly overestimating the contributions from the impactor? Was the mixing of building-block materials throughout the inner solar system much less than

Target therapy is a promising strategy for advanced hepatoma; however, targeted accumulation and controlled release of therapeutic agents into the metastatic site is still a great challenge. Folic acid (FA and paclitaxel (PTX containing composite micelles (FA-M[PTX] were prepared by coassembling the FA polymer conjugate and PTX polymer conjugate. The main purpose of this study is to investigate the inhibitory efficacy of FA-M(PTX on the pulmonary metastasis of intravenously injected murine hepatoma 22 (H22 on BALB/c mice models. The lung metastatic burden of H22 were measured and tissues were analyzed by immunohistochemistry and histology (hematoxylin and eosin stain, followed by survival analysis. The results indicated that FA-M(PTX prevented pulmonary metastasis of H22, and the efficacy was stronger than pure PTX and simple PTX-conjugated micelles. In particular, the formation of lung metastasis colonies in mice was evidently inhibited, which was paralleled with the downregulated expression of matrix metalloproteinase-2 and matrix metalloproteinase-9. Furthermore, the mice bearing pulmonary metastatic hepatoma in the FA

In this Letter, we study the possibility of building a model of the oscillating universe with quintom matter in the framework of 4-dimensional Friedmann-Robertson-Walker background. Taking the two-scalar-field quintom model as an example, we find in the model parameter space there are five different types of solutions which correspond to: (I) a cyclic universe with the minimal and maximal values of the scale factor remaining the same in every cycle, (II) an oscillating universe with its minimal and maximal values of the scale factor increasing cycle by cycle, (III) an oscillating universe with its scale factor always increasing, (IV) an oscillating universe with its minimal and maximal values of the scale factor decreasing cycle by cycle, and (V) an oscillating universe with its scale factor always decreasing

The approach to particle physics via cosmology may meet with an obstacle in a series of cosmological puzzles studied in this paper: the flatness-longevity puzzle, the horizon-homogenity puzzle, and the cosmological constant puzzle. An analysis of the geometry and dynamics of the universe leads to an understanding (but not solution) of the flatness-longevity puzzle: possible universes are distinguished by the value of the dimensionless quantity N, the coordinate density of ER particles, such that the longevity of the universe is fixed by N. Universes where nonrelativistic particles dominate are then studied. An inflationary scenario proposed as a solution to these puzzles is studied, but found to have some difficulties

The authors were aware of the Kang et al.'s paper, since they cite it several times in the manuscript published in GMR. Some of the language is similar between the two manuscripts, but what is the most concerning is that several of the tables in the papers are nearly identical. Tables 2 and 3 are exactly identical between the two articles, suggesting that the publication in GMR was plagiarized from the publication in the International Journal of Clinical Experimental Pathology. The Publisher and Editor decided to retract these articles in accordance with the recommendations of the Committee on Publication Ethics (COPE). After a thorough investigation, we have strong reason to believe that the peer review process was failure and, after review and contacting the authors, the editors of Genetics and Molecular Research decided to retract the article.

Fluorescent mesoporous silica-coated superparamagnetic iron oxide nanoparticles (fmSiO4@SPIONs were prepared by growing fluorescent dye-doped silica onto superparamagnetic iron oxide nanoparticles (SPIONs directed by a cetyltrimethylammonium bromide template. As prepared, fmSiO4@SPIONs had a uniform size, a large surface area, and a large pore volume, which demonstrated high efficiency for iodinated oil loading. Iodinated oil loading did not change the sizes of fmSiO4@SPIONs, but they reduced the MRI T2 relaxivity (r2 markedly. I-fmSiO4@SPIONs were stable in their physical condition and did not demonstrate cytotoxic effects under the conditions investigated. In vitro studies indicated that the contrast enhancement of MRI and CT, and the fluorescence signal intensity of i-fmSiO4@SPION aqueous suspensions and macrophages, were intensified with increased i-fmSiO4@SPION concentrations in suspension and cell culture media. Moreover, for the in vivo study, the accumulation of i-fmSiO4@SPIONs in the liver could also be detected by MRI, CT, and fluorescence imaging. Our study demonstrated that i-fmSiO4@SPIONs had great potential for MRI/C/fluorescence trimodal imaging.Keywords: multifunctional probe, SPIONs, mesoporous silica

Gene therapy was established as a new strategy for treating HCC. To explore the potential delivery system to support the gene therapy of HCC, negatively charged liposomal delivery system was used to deliver miR-221 antisense oligonucleotide (anti-miR-221 to the transferrin (Tf receptor over expressed HepG2 cells. The liposome exhibited a mean particle size of 122.5 nm, zeta potential of -15.74 mV, anti-miR-221 encapsulation efficiency of 70%, and excellent colloidal stability at 4°C. Anti-miR-221-encapsulated Tf-targeted liposome demonstrated a 15-fold higher delivery efficiency compared to nontargeted liposome in HepG2 cells in vitro. Anti-miR-221 Tf-targeted liposome effectively delivered anti-miR-221 to HepG2 cells, upregulated miR-221 target genes PTEN, P27kip1, and TIMP3, and exhibited greater silencing efficiency over nontargeted anti-miR-221 liposome. After intravenous injection into HepG2 tumor-bearing xenografted mice with Cy3-labeled anti-miR-221 Tf-targeted liposome, Cy3-anti-miR-221 was successfully delivered to the tumor site and increased the expressions of PTEN, P27kip1, and TIMP3. Our results demonstrate that the Tf-targeted negatively charged liposome could be a potential therapeutic modality in the gene therapy of human HCC.
