During the second stage of an illness caused by Borrelia burgdorferi, a young woman developed a myopathic syndrome characterised by severe muscular pains, incapacitating weakness of the proximal limb and the neck, as well as the bulbar muscles and elevated serum CK levels. Muscle biopsy revealed a non-inflammatory necrotising myopathy. B. burgdorferi infection was confirmed by a considerable rise of specific IgG antibodies. A course of high dose steroids alleviated the myalgias, but paresis began to improve only after treatment with antibiotics. Our observations confirm that B burgdorferi can cause, through an undertermined mechanism, a necrotising myopathy, in addition to the wide spectrum of already known neurological complications.

Glucocorticoids mediate muscle atrophy in many catabolic states. Myostatin expression, a negative regulator of muscle growth, is increased by glucocorticoids and myostatin overexpression is associated with lower muscle mass. This suggests that myostatin is required for the catabolic effects of glucocorticoids. We therefore investigated whether myostatin gene disruption could prevent muscle atrophy caused by glucocorticoids. Male myostatin knockout (KO) and wild-type mice were subjected to dexamethasone treatment (1 mg/kg.d for 10 d or 5 mg/kg.d for 4 d). In wild-type mice, daily administration of low-dose dexamethasone for 10 d resulted in muscle atrophy (tibialis anterior: -15%; gastrocnemius: -13%; P < 0.01) due to 15% decrease in the muscle fiber cross-sectional area (1621 +/- 31 vs. 1918 +/- 64 mu m(2), P < 0.01). In KO mice, there was no reduction of muscle mass nor fiber cross-sectional area after dexamethasone treatment. Muscle atrophy after 4d of high-dose dexamethasone was associated with increased mRNA of enzymes involved in proteolytic pathways (atrogin-1, muscle ring finger 1, and cathepsin L) and increased chymotrypsin-like proteasomal activity. In contrast, the mRNA of these enzymes and the proteasomal activity were not significantly affected by dexamethasone in KO mice. Muscle IGF-I mRNA was paradoxically decreased in KO mice (-35%, P < 0.05); this was associated with a potentially compensatory increase of IGF-II expression in both saline and dexamethasone-treated KO mice (2-fold, P < 0.01). In conclusion, our results show that myostatin deletion prevents muscle atrophy in glucocorticoid-treated mice, by blunting the glucocorticoid-induced enhanced proteolysis, and suggest an important role of myostatin in muscle atrophy caused by glucocorticoids.

Le rapport de Mallarmé à la réclame en général est très contradictoire : d'un côté, opposition de principe, conforme à la position artiste ; de l'autre, intégration subtile mais aussi toute pratique à l'esthétique et au montage éditorial du Livre. Comme le montre par excellence un article tel qu’« Étalages », parmi d'autres proses critiques réservées au livre et à l'édition, ce rapport est inséparable d'une réflexion sur les effets de promotion et d'annonce autant que sur les discours de crise et de récession propres au champ éditorial de la fin du XIXe siècle. Un champ où le livre — ou bien encore la « mentale denrée » — n'échappe pas moins que d'autres denrées aux fantasmagories mystérieuses de la marchandise. [less ▲]

The discovery of ancient footprints and spraints (faeces) of European Otter in the caves of Arcy-sur-Cure (Yonne), renowned for their great archaeological interest, has led the scientific team of the Museum of Natural Sciences of Orleans to launch an original archaeozoological study. The analyzes allowed, on the one hand, to date the deposits of spraints and, on the other hand, to know the main preys of these “cave otters” after the remains of prey contained in the spraints... This extensive study is among the first of its kind in France, regarding otters who frequently used an underground river a thousand years ago ! [less ▲]

In microfluidics flow focusing is widely used to produce water-in-oil droplets in microchannels at high frequency. Nevertheless, the scaling laws associated to droplet length, speed and frequency could not be identified yet, owing to the large number of parameters involved (incl. complex geometry). We here present an experimental study of droplet formation in a microfluidic cross-junction with a minimum number of geometrical parameters. We mostly focus on the dripping regime. The formation sequence is decomposed in two steps, inflation and squeezing, that vary differently according to both water and oil flow rates. These variations reveal several insights about the fluid flows in both phases. From there we infer the scaling law that relates droplet volume and frequency to the Capillary number associated to each inlet flow rate. This law involves a minimum of fitting parameters. We finally discuss the influence of inlet control (flow rate vs. pressure) and surfactants on the formation dynamics. [less ▲]

Ichthyosaurs rapidly diversified and colonised a wide range of ecological niches during the Early and Middle Triassic period, but experienced a major decline in diversity near the end of the Triassic. Timing and causes of this demise and the subsequent rapid radiation of the diverse, but less disparate, parvipelvian ichthyosaurs are still unknown, notably because of inadequate sampling in strata of latest Triassic age. Here, we describe an exceptionally large radius from Lower Jurassic deposits at Penarth near Cardiff, South Wales (UK) the morphology of which places it within the giant Triassic shastasaurids. A tentative total body size estimate, based on a regression analysis of various complete ichthyosaur skeletons, yields a value of 12-15 m. The specimen is substantially younger than any previously reported last known occurrences of shastasaurids and implies a Lazarus range in the lowermost Jurassic for this ichthyosaur morphotype.
