Resumen

Mutations in rcsC that result in constitutive colanic acid capsule synthesis were obtained in Salmonella enterica serovar Typhimurium. Most rcsC alleles were dominant; however, recessive rcsC alleles were also found, in agreement with the postulated double role (positive and negative) of RcsC on the activation of the RcsB/C phosphorelay system. Salmonella rcsC mutants with constitutive activation of the Rcs system are severely attenuated for virulence in BALB/c mice and their degree of attenuation correlates with the level of Rcs activation. Partial relief of attenuation by a gmm mutation indi

Resumen

Abstract Chronic lymphocytic leukemia (CLL) is the most common leukemia in the Western hemisphere, but its pathogenesis is still poorly understood. Constitutive tyrosine phosphorylation (p) of signal transducer and activator of transcription (STAT) 3 occurs in several solid tumors and hematologic malignancies. In CLL, however, STAT3 is constitutively phosphorylated on serine 727, not tyrosine 705, residues. Because the biologic significance of serine pSTAT3 in CLL is not known, we studied peripheral blood cells of 106 patients with CLL and found that, although tyrosine pSTAT3 was inducible, se

Resumen

Cyclooxygenase-2 (COX-2) is an inducible enzyme that drives inflammation and is the therapeutic target for widely used nonsteroidal antiinflammatory drugs (NSAIDs). However, COX-2 is also constitutively expressed, in the absence of overt inflammation, with a specific tissue distribution that includes the kidney, gastrointestinal tract, brain, and thymus. Constitutive COX-2 expression is therapeutically important because NSAIDs cause cardiovascular and renal side effects in otherwise healthy individuals. These side effects are now of major concern globally. However, the pathways driving constit

Resumen

Parasites represent a major threat to all organisms which has led to the evolution of an array of complex and effective defence mechanisms. Common to both vertebrates and invertebrates are innate immune mechanisms that can be either constitutively expressed or induced on exposure to infection. In nature, we find that a combination of both induced and constitutive responses are employed by vertebrates, invertebrates and, to an extent, plants when they are exposed to a parasite. Here we use a simple within-host model motivated by the insect immune system, consisting of both constitutive and indu

The nonlinear constitutive relations of clay are investigated with different initial stress conditions. Two series of triaxial compression tests are performed, respectively after consolidation and isotropic consolidation. On the basis of the framework of ~ model, a uniform nonlinear constitutive model is proposed by fitting of the test data. With the average slope of the unloading-reloading curve selected as the unloading modulus, the unloading function is constructed as the loading-unloading criterion. Moreover, a comparison of the experimental stress-strain curves with the predicted results

Fair play as a phenomenon of sporting life is present even if only in the form of small acts or gestures in most competitions; its absence is present in cases of foul play. The daily press comments its presence or absence every day in, and not only in the sports sections. Both the public and experts discuss acts from so called grey zone (forms of gamesmanship). Deciding unequivocally on the moral quality of a diverse range of actions, attitudes or statements requires clarity about the values underpinning fair play.

Resumen

Abstract The central melanocortin (MC) system has been demonstrated to act downstream of leptin in the regulation of body weight. The system comprises α-MSH, which acts as agonist, and agouti-related protein (AgRP), which acts as antagonist at the MC3 and MC4 receptors (MC3R and MC4R). This property suggests that MCR activity is tightly regulated and that opposing signals are integrated at the receptor level. We here propose another level of regulation within the melanocortin system by showing that the human (h) MC4R displays constitutive activity in vitro as assayed by adenylyl cyclase (AC) a

However, certain mutants with defects in DNA replication, recombination, or repair exhibit a partially constitutive SOS response. These mutants presumably suffer frequent replication fork failure, or perhaps they have difficulty rescuing forks that failed due to endogenous sources of DNA damage. In an effort to understand more clearly the endogenous sources of DNA damage and the nature of replication fork failure and rescue, we undertook a systematic s

Resumen

The paper explores the incentive structures and the structurally rigid social hierarchies inherent in the polarizing logic of modern credit money and the mutual constitution of money’s sovereign and biopolitical dimensions. It is argued that the monetary system constitutes a major transitory channel for the logic of financial capital to transcend the limitations of sovereign spaces and to transform itself into a biopolitical force. The relationship between the material and the subjective – or the sovereign and the biopolitical – dimensions of money is seen as di-polaric rather than di-chotomic

Resumen

Acetic acid bacteria are well-known for their ability to incompletely oxidize their carbon sources. Many of the products of these oxidations find industrial uses. Metabolic engineering of acetic acid bacteria would improve production efficiency and yield by allowing controllable gene expression. However, the molecular tools necessary for regulating gene expression have only recently started being explored. To this end the ability of the activation-dependent Plux system and two constitutive repression Ptet systems were examined for their ability to modulate gene expression in Gluconobacter oxyd

Resumen

To ensure ammunition safety, a protective structure and pressure detection system are essential; however, there is a lack of an accurate constitutive model to describe the mechanical response characteristics of protective structures composed of various polymer materials. In this work, a constitutive model for the composite structure based on the superposition principle is successfully constructed derived from the quasi-static compression behavior of rigid polyurethane foam (RPUF), silicone rubber foam (SRF), and flexible pressure sensors (FPSs) through experimental investigations.

Resumen

Lichens are symbiotic associations (holobionts) established between fungi (mycobionts) and certain groups of cyanobacteria or unicellular green algae (photobionts). This symbiotic association has been essential in the colonization of terrestrial dry habitats. Lichens possess key mechanisms involved in desiccation tolerance (DT) that are constitutively present such as high amounts of polyols, LEA proteins, HSPs, a powerful antioxidant system, thylakoidal oligogalactolipids, etc. This strategy allows them to be always ready to survive drastic changes in their water content.

Resumen

The nonequilibrium Statistical Operator Method, seemingly contained within the scope of Jaynes’ Predictive Statistical Mechanics, provides a foundation for irreversible thermodynamics in what is called Informational Statistical Thermodynamics, and within it a way of deriving generalized constitutive equations which contain non-localities on space. Here we present a derivation of these equations of evolution describing how memory effects are incorporated into the theory. We show that the memory kernels in the kinetic coefficients and relaxation times can be expressed in terms of an infinite ser

Resumen

The increasing need for energy storage technology has led to a massive interest in novel energy storage methods. The energy geomembrane system is such a novel energy storage method. The concept of the system is briefly introduced, and a holistic numerical model of the system is presented. The model uses advanced finite-element techniques to model the energy storage system using fluid cavity elements. The developed geomembrane energy system is modelled with different constitutive models to represent the soil behaviour: a linear elastic model, a nonlinear Mohr-Coulomb model, and a hypoplastic co

The system that deals with unfairness in civil transactions in China has been continuously improved as a result of the dynamic nature of the market economy. The objective is to deter inequitable conditions and transactions in civil exchanges, guaranteeing that contractual parties participate in commerce founded on principles of equity and free will. This paper examines the fundamental components of unjust legal actions as outlined in the Chinese Civil Code. It investigates how these elements are applied and evolved in legal practice, and draws comparisons with similar legal systems worldwide,

Resumen

ABSTRACTMutations that cause the constitutive expression of the PHO regulon ofEscherichia colioccur either in thepstoperon or in thephoRgene, which encode, respectively, a high-affinity Pitransport system and a histidine kinase sensor protein. These mutations are normally selected on glycerol-2-phosphate (G2P) as the carbon source in the presence of excess Pi. The emergence of early PHO-constitutive mutants, which appear after growth for up to 48 h on selective medium, depends on the presence ofphoA, which codes for a periplasmic alkaline phosphatase, while late mutants, which appear after 48

Resumen

In order to obtain the dynamic shearing property of high N alloy steel, the plugging test was performed by using the improved Hopkinson pressure bar system. As dynamic shearing strengths, the dynamic shearing energies during plugging process of two type high N alloy steels were determined from the shearing constitutive relationship at different super high strain rates. According to the theory of dislocation dynamics in Seeger equation, a dynamic shearing damage constitutive relationship was established and the different parameters of this material were determined by using the curve fitting met

Identification of a bird constitutive model and its parameters is a very difficult work in bird-impact coupling solution. In order to identify the constitutive model and the parameters simultaneously, an inversion analytic model for the bird material parameters is given based on penalty function method and nonlinear optimization principle, and then combining the model preferential criterion proposed in this paper, the identification system of the bird constitutive model is established with ANSYS Parametric Design Language (APDL). Finally, the feasibility and practicability of this identificati

Resumen

AbstractThe two standard interpretations of Kant’s view of the relationship between external freedom and public law make one of the terms a means for the production of the other: either public law is justified as a means to external freedom, or external freedom is justified as a means for producing a system of public law. This article defends an alternative, constitutive interpretation: public law is justified because it is partly constitutive of external freedom. The constitutive view requires conceiving of external freedom in a novel, second-personal way, that is, as an irreducibly relationa

Resumen

Frictional constitutive law for very slow vertical withdrawing of a thin rod from a granular bed is experimentally studied. Using a very precise creep meter, geometry-dependent granular frictional constitutive law is particularly examined. In some previous works, a dimensionless number [Formula: see text] has been used to characterize granular frictional constitutive laws, where [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] are the shear strain rate, grain diameter, confining pressure, and bulk density of granular bed, respectively.
