We prove two formulae that express the Alexander polynomial C of several variables of a plane curve singularity C in terms of the ring O C of germs of analytic functions on the curve. One of them expresses C in terms of dimensions of some factors corresponding to a (multi-indexed) filtration on the ring O C. The other one gives the coefficients of the… (More)

The ototoxicity of antibiotics, particularly of aminoglycosides, is a well-known undesirable side effect which may be based on a free radical mechanism. We studied the effect of different antibiotics in the production of reactive oxygen species in freshly isolated cochleas of mature and 2-10 weeks old developing rats. Phorbol myristate acetate induced the… (More)

Integrals with respect to the Euler characteristic over spaces of functions and the Alexander polynomial. Recently there were obtained some formulae which express the Alexan-der polynomial (and thus the zeta-function of the classical monodromy transformation) of a plane curve singularity in terms of the ring of functions on the curve: [10]. One of them… (More)

Mycobacterium bovis is the causative agent of tuberculosis in cattle but also infects other animals, including humans. Previous studies in cattle have demonstrated that the protection induced by BCG is not complete. In order to improve the protection efficacy of BCG, in this study we overexpressed Ag85B in a BCG Pasteur strain, by using an expression system… (More)

Let a finite group G act on the complex plane (C 2 , 0). We consider multi-index filtrations on the spaces of germs of holomorphic functions of two variables equivariant with respect to 1-dimensional representations of the group G defined by components of a modification of the complex plane C 2 at the origin or by branches of a G-invariant plane curve… (More)

We give two formulae which express the Alexander polynomial ∆ C of several variables of a plane curve singularity C in terms of the ring O C of germs of analytic functions on the curve. One of them expresses ∆ C in terms of dimensions of some factorspaces corresponding to a (multi-indexed) filtration on the ring O C. The other one gives the coefficients of… (More)

BACKGROUND
Bovine herpesvirus 5 (BoHV-5) is an alphaherpesvirus responsible for meningoencephalitis in young cattle and it is antigenically and genetically related to bovine herpesvirus 1. BoHV-5 outbreaks are sporadic and restricted in their geographical distribution, being mostly detected in the Southern hemisphere. The N569 and A663 strains are… (More)

Bonds issued by the government or government agencies are often used to finance bank restructuring following a systemic crisis. Many conflicting considerations affect the design of the bonds used to pay for public sector investment in bank equity or the purchase of distressed assets from banks. Some bond features can leave restructured banks facing… (More)

Rat cochleas were analysed for free oxygen radicals (FOR) and nitric oxide (NO) production by the chemiluminescent oxidation of luminol. 4Beta-phorbol-12beta-myristate-13alpha-acetate (PMA), a well-known agonist of protein kinase C, induced the release of FOR after a time lag close to 30 s and reverted to basal values in approximately 10 min. Sphingosine… (More)
