Massive systems made of two or more stars are known to be the site for interesting physical processes -- including at least in some cases -- particle acceleration. Over the past decade, this topic motivated a particular effort to unveil the properties of these systems and characterize the circumstances responsible for the acceleration of particles and the potential role of pre-supernova massive stars in the production of high energy particles in our Galaxy. Although previous studies on this topic were mostly devoted to processes in general, or to a few individual objects in particular, a unified target-oriented census of particle-accelerating colliding-wind binaries (hereafter PACWBs) does not exist yet. This paper aims at making a general and unified census of these systems, emphasizing their main properties. A general discussion includes energetic considerations along with wind properties in relation with non-thermal emission processes that are likely at work in colliding-wind binaries. Finally, some guidelines for future observational and theoretical studies are drawn. [less ▲]

The Viséan ‘black marble’ of Denée is one of the best preserved Mississippian fossil assemblages. This Lagerstätte is famous for the exceptional preservation of several groups of macro-organisms (fishes, echinoids, graptolites). However, only a part of the fauna has received attention from specialists and most of the phyla may benefit from a modern revision based on new investigative techniques such as 3D imagery and CT-scanning. Almost all the specimens illustrated in the literature have been traced and we present here a comprehensive catalogue of this material. Representatives of several minor groups are photographically illustrated for the first time as well as five emblematic specimens of the styracopterid genus Benedenius (Pisces). For purposes of nomenclatural formality, the lectotypes of Benedenius deneensis Traquair (in de Koninck, 1878), B. soreili Fraipont, 1890, Oligoporus soreili Fraipont, 1904, Taeniaster? fournieri Fraipont, 1904, and Scaphiocrinus longicaudatus Fraipont, 1904 are here selected.

We report here on the role of copper (II) salts on the acceleration of peroxynitrite (ONOO-) decomposition and ONOO- reaction with the anaesthetic agent propofol (2,6-diisopropylphenol) in alkaline medium. We observed a strong acceleration of the ONOO- decomposition in alkaline medium in the presence of copper (I and II) salts. After 18 h of ONOO- reaction with propofol, we observed nitrosated, nitrated, and oxidized (quinone and diphenylquinone) derivatives of propofol, but in the presence of Cu(II) (20% molar vs ONOO-), the yields of quinone and nitrosopropofol strongly increased. We also observed that the temperature and the atmosphere influenced the effects of Cu(II) on ONOO- reactions with propofol: low temperatures promoted nitrosation and high temperatures promoted oxidation; O-2 atmosphere increased the general reactivity and the yield of nitrated and oxidized products. We highlighted the influence of Cu(II) salts on the radical character of the reaction by direct EPR technique. The exact mechanism of the Cu(II) catalysis remains unexplained, but we suggest the formation of a copper complex with propofol or, more probably, the oxidation of ONOO- into ONOO• by copper ions promoting the formation of quinone and nitrosopropofol according to a previously reported mechanism [M. Cudic, C. Ducrocq, Transformations of 2,6-diisopropylphenol by NO-derived nitrogen oxides, particularly peroxyrutrite, Nitric Oxide 4 (2000) 147-156]. © 2005 Elsevier Inc. All rights reserved.

The Km, app. values of the membrane-bound transpeptidase of Streptomyces R61 for the donor Ac2-L-Lys-D-Ala-D-Ala and the acceptor Gly-Gly are not affected by temperature variations when the reaction mixtures are incubated in liquid suspensions. At -5 degrees C, the incubation can be carried out either in the liquid or in the frozen state. The enzyme is active in the latter state. In the frozen state, the Km, app. value for the acceptor remains unchanged but there is a 3-fold increase in the maximum velocity, a 10-fold decrease of the Km, app. value for the donor and a 10-fold increase of the benzylpenicillin concentration required to inhibit the enzyme activity by 50% (ID50 value). Temperatures of -35 degrees C or below are required to completely inhibit the membrane-bound enzyme in the frozen state. Cetyltrimethylammonium bromide extracts the transpeptidase both from the isolated membranes and, with a much higher yield, from the intact mycelium. The extracted enzyme is not active in the frozen state, requires detergent for activity, has decreased Km, app. values for both donor and acceptor, exhibits the same sensitivity to benzylpenicillin and cephalosporin C as the membrane-bound transpeptidase (in liquid suspensions) and, like this latter enzyme, has no DD-carboxypeptidase activity. The detergent-extracted transpeptidase penetrates gels of Sephadex-100 and is not sedimented at 200 000 X g. [less ▲]
