How to pay for the war in times of imperfect commitment. Adam Smith and David Ricardo on the Sinking Fund

2014

AbstractThe paper proposes a comparative analysis of Smith's and Ricardo's views on the sinking fund. It shows that Smith and Ricardo agreed in stressing the ineffectiveness of the sinking fund as a policy instrument targeted at public debt repayment and tax-burden relief, pointing out that its actual workings had paradoxically helped to increase rather than reduce British total debt-load. Moreover, their explanation of the sinking fund paradox integrates a defective fiscal commitment technology with powerful politicians’ incentives to siphon off the money stored in the sinking fund to meet sudden increases of public expenditure whenever the occasion arose.

Open ADAMTS13, induced by antibodies, is a biomarker for subclinical immune-mediated thrombotic thrombocytopenic purpura

2020

Recently, we showed that ADAMTS13 circulates in an open conformation during the acute phase of immune-mediated thrombotic thrombocytopenic purpura (iTTP). Although the cause of this conformational change remains elusive, ADAMTS13 is primarily closed in iTTP patients in remission with ADAMTS13 activity >50% and undetectable anti-ADAMTS13 autoantibodies, as well as after rituximab treatment, suggesting a role for anti-ADAMTS13 autoantibodies. Therefore, immunoglobulin G from 18 acute iTTP patients was purified and added to closed ADAMTS13 in healthy donor plasma. This resulted in open ADAMTS13 in 14 of 18 (78%) samples, proving that anti-ADAMTS13 autoantibodies can induce an open ADAMTS13 con…

Extract of Caragana sinica as a potential therapeutic option for increasing alpha-secretase gene expression

2015

Abstract Background Alzheimer's disease represents one of the main neurological disorders in the aging population. Treatment options so far are only of symptomatic nature and efforts in developing disease modifying drugs by targeting amyloid beta peptide-generating enzymes remain fruitless in the majority of human studies. During the last years, an alternative approach emerged to target the physiological alpha-secretase ADAM10, which is not only able to prevent formation of toxic amyloid beta peptides but also provides a neuroprotective fragment of the amyloid precursor protein – sAPPalpha. Purpose To identify novel alpha-secretase enhancers from a library of 313 extracts of medicinal plant…

Glia talk back.

This study shows that the activity of neurons can trigger shedding of a protein, NG2, from the surface of oligodendrocyte precursor cells; this protein in turn modulates synaptic transmission, revealing a two-way conversation between neurons and glia.

Multifocal aplasia cutis congenita, distal limb hemimelia, and cutis marmorata telangiectatica in a patient with Adams-Oliver syndrome.

1992

Summary We describe an 18-month-old boy with multifocal scalp defects over the posterior parietal region combined with an underlying defect of the skull, left lower limb distal hemimelia and generalized cutis marmorata telangiectatica, consistent with a diagnosis of Adams–Oliver syndrome (aplasia cutis congenita with distal transverse limb defects).

Acitretin, an Enhancer of Alpha-Secretase Expression, Crosses the Blood-Brain Barrier and Is Not Eliminated by P-Glycoprotein

2011

<i>Background:</i> ADAM10 (a disintegrin and metalloproteinase 10) has been demonstrated to act as the main physiological α-secretase. Enzymatic activity of the α-secretase on the one hand prevents the formation of toxic Aβ peptides and on the other hand promotes the secretion of a neurotrophic and neuroprotective amyloid precursor protein fragment (APPs-α) by cleaving the amyloid precursor protein within its Aβ sequence. Enhancement of ADAM10’s gene expression may therefore present a valuable therapeutic approach for the treatment of Alzheimer’s disease (AD), where Aβ peptides are severely involved in the pathogenesis. <i>Objective:</i> In cell culture and in a tran…

The Carbon Monoxide-Releasing Molecule Tricarbonyldichlororuthenium(II) Dimer Protects Human Osteoarthritic Chondrocytes and Cartilage from the Catab…

2008

We have investigated the effects of a carbon monoxide-releasing molecule, tricarbonyldichlororuthenium(II) dimer (CORM-2), on catabolic processes in human osteoarthritis (OA) cartilage and chondrocytes activated with interleukin-1beta. In these cells, proinflammatory cytokines induce the synthesis of matrix metalloproteinases (MMPs) and aggrecanases, including members of a disintegrin and metalloproteinase with thrombospondin domain (ADAMTS) family, which may contribute to cartilage loss. CORM-2 down-regulated MMP-1, MMP-3, MMP-10, MMP-13, and ADAMTS-5 in OA chondrocytes, and it inhibited cartilage degradation. These effects were accompanied by increased aggrecan synthesis and collagen II e…
