Cleavage of IgG1 and IgG3 by gingipain K from Porphyromonas gingivalis may compromise host defense in progressive periodontitis

Degradation of immunoglobulins is an effective strategy of bacteria to evade the immune system. We have tested whether human IgG is a substrate for gingipain K of Porphyromonas gingivalis and found that the enzyme can hydrolyze subclass 1 and 3 of human IgG. The heavy chain of IgG(1) was cleaved at a single site within the hinge region, generating Fab and Fc fragments. IgG(3) was also cleaved within the heavy chain, but at several sites around the CH2 region. Investigation of the enzyme kinetics of IgG proteolysis by gingipain K, using FPLC- and isothermal titration calorimetry-based assays followed by Hill plots, revealed non-Michaelis-Menten kinetics involving a mechanism of positive cooperativity. In ex vivo studies, it was shown that gingipain K retained its IgG hydrolyzing activity in human plasma despite the high content of natural protease inhibitors; that IgG(1) cleavage products were detected in gingival crevicular fluid samples from patients with severe periodontitis; and that gingipain K treatment of serum samples from patients with high antibody titers against P. gingivalis significantly hindered opsonin-dependent phagocytosis of clinical isolates of P. gingivalis by neutrophils. Altogether, these findings underline a biological function of gingipain K as an IgG protease of pathophysiological importance.

Perpetual Conflict or Compromise? The Cost of Domestic Legitimacy in the Realm of Women's Human Rights: A Case Study on the Right to an Abortion

With its turbulent and volatile legal evolution, the right to an abortion in the United States still remains a highly contested issue and has developed into one of the most divisive topics within modern legal discourse. By deconstructing the political underpinnings and legal rationale of the right to an abortion through a systematic case law analysis, I will demonstrate that this right has been incrementally destabilized. This instability embedded in abortion jurisprudence has been primarily produced by a combination of textual ambiguity in the case law and judicial ambivalence regarding this complex area of law. In addition, I argue that the use of the largely discredited substantive due process doctrine to ground this contentious right has also contributed to the lack of legal stability. I assert that when these elements culminate in the realm of reproductive privacy the right to terminate a pregnancy becomes increasingly unstable and contested.

Very high methane uptake on activated carbons prepared from mesophase pitch: A compromise between microporosity and bulk density

Two petroleum residues were pyrolyzed under two different conditions to obtain pitches with low or high mesophase content. The effect of the KOH: precursor ratio and the activation temperature on the packing density and porous texture of the carbons have been studied and optimized. Activated carbons combining high micropore volume (>1 cm3/g) and high packing density (0.7 g/cm3) have been successfully prepared. Regarding excess methane adsorption capacities, the best results (160 cm3 (STP)/cm3 at 25 °C and 3.5 MPa) were obtained using the pitch with the higher content of the more organized mesophase, activated at relatively low temperature (700 °C), with a medium KOH: precursor ratio (3:1). Some of the activated carbons exhibit enhanced adsorption capacity at high pressure, giving values as high as 175 cm3 (STP)/cm3 at 25 °C and 5 MPa and 200 cm3 (STP)/cm3 at 25 °C and 10 MPa (the same amount as in an empty cylinder but at half of the pressure), indicating a contribution of large micropores and narrow mesopores to adsorption at high pressure. The density of methane in pores between 1 and 2.5 nm at pressure up to 10 MPa was estimated to understand their contribution to the total adsorption capacity.

Bank bonus compromise bodes ill for the Single Supervisory Mechanism. CEPS Commentary, 8 March 2013

The European Parliament has probably won a Pyrrhic victory with its position on bank bonuses, argues CEPS CEO Karel Lannoo in this new Commentary. In return, EU member states got what they wanted with the new Capital Requirements Directive (CRD IV): no binding leverage ratio; mortgage risk weightings and capital add-ons to be determined by member states; and no obligatory consolidated capital position for bank-insurance companies. In other words, Banking Union will start out with capital rules that are more like Emmental cheese than a single rulebook. This is a huge encumbrance for a well-functioning Single Supervisory Mechanism (SSM), and makes a single resolution mechanism impossible.

The Bank Resolution Compromise: Incomplete, but workable? CEPS Commentary, 19 December 2013

Calling the Single Resolution Mechanism an “inelegant step in the right direction”, this Commentary singles out the Single Resolution Fund, with its considerable mutualisation of risk, as the key advance – but one that will require changes over time in the extremely complex decision-making mechanisms agreed.

Modell Deutschland as an Interdenominational Compromise, CES Germany & Europe Working Papers, No. 00.3, 2000

Usually, Germany’s social market economy is understood to embody a compromise between a liberal market order and a corporatist welfare state. While this reading of the German case is certainly not entirely wrong, this paper argues that only if we account for the close intellectual correspondence between lutheran Protestantism and economic liberalism on the one hand and between Catholicism and welfare corporatism on the other, can we fully comprehend the nature of the German post-war compromise. In particular, this perspective allows to better explain the anti-liberal undercurrents of Germany’s soziale Marktwirtschaft. It was especially the role which Protestant Ordoliberals ascribed to the state in upholding economic order and market discipline which accounts for the major difference between ‘classic’ and ‘German-style’ economic liberalism. Yet, the postwar economic order did not represent a deliberately struck compromise between the two major Christian denominations. Rather, Germany’s social market economy was the result of the failure of German Protestant Ordoliberals to prevent the reconstruction of the catholic Bismarckian welfare state after the authoritarian solution, which Ordoliberals had endorsed so strongly up until 1936 and from which they had hoped the re-inauguration of Protestant hegemony, had so utterly failed. Since the ordoliberal doctrine up to the present day lacks a clear understanding of the role of the corporatist welfare state within the German political economy, its insights into the functioning logic of German capitalism have remained limit. The paper also claims that accounting for the denominational roots of the postwar compromise allows us to better understand the relationship between consociationalism and corporatism in ‘Modell Deutschland’.

Dominance, Competition, Compromise or Consensus? Explaining Decision-Making Structures

The previous chapter uncovered important differences between decision-making structures across the 11 processes investigated by this study. As we have noted, both historically and in much contemporary literature, the Swiss political system has been described as highly consensual. And yet, when we focus on differences between decision-making structures across different policy domains, important elements appear that point toward a more conflictual style of decision-making. Both when there is a power balance between coalitions and in the presence of a dominant coalition, coalition interactions are conflictual in the majority of cases. Based on the descriptive account of these differences in Chapter 4, the present chapter studies the conditions under which given decision-making structures emerge. Under which circumstances are actors able to form a dominant coalition, and which conditions lead to a situation where power is more evenly balanced between coalitions? Which conditions lead actors to develop a conflictual rather than a consensual type of interaction? Answering these questions can give us some indication of the factors responsible for different types of decision-making structures.
