The regulatory mechanism of centrosome function is crucial to the accurate transmission of chromosomes to the daughter cells in mitosis. Recent findings on the posttranslational modifications of many centrosomal proteins led us to speculate that these modifications might be involved in centrosome behavior. Poly(ADP-ribose) polymerase 1 (PARP-1) catalyzes poly(ADP-ribosyl)ation to various protei...

In practice, central banks have been confronted with a trade-o¤ between stabilising in‡ation and output when dealing with rising oil prices. This contrasts with the result in the standard New Keynesian model that ensuring complete price stability is the optimal thing to do, even when an oil shock leads to large output drops. To reconcile this apparent contradiction, this paper investigates how ...

To better understand productivity and in‡ation in the health sector, health economists have advocated tracking the cost of treatment by disease over time. However, there are several methods for measuring the cost of treatment, and little work has been done to understand how di¤erent approaches a¤ect disease-price in‡ation. In this paper we compare various methodologies for allocating expenditur...

This article proposes an empirical representation of the in‡ation expectations in an Unobserved Components model with Markov-Switching regimes. This State-Space representation aims to answer two questions. Are the expectation errors consistent with the weak form of the Rational Expectations Hypothesis? If this is not the case for certain periods, are the di¤erent schemes of expectation associat...

Calf thymus poly(ADP-ribose) synthetase (Mr = 120,000) is cleaved with papain into two fragments of M(r) = 74,000 and 46,000 and also split with chymotrypsin into two fragments of M(r) = 66,000 and 54,000. Each fragment purified to homogeneity is enzymatically inactive, but combined incubation of the 74,000 and 46,000 fragments in the presence of DNA restored 20% of the enzyme activity. In cont...

Le concept de coopétition fait l’objet d’une littérature récente et dense, mais ses mécanismes doivent encore être approfondis. Parmi ceux-ci, nous intéressons particulièrement aux différentes formes création valeur attendues lorsque la concerne des TPE.Notre étude, qui s’inscrit dans une démarche compréhensive, est c...
