Sea surface temperature (SST) derived from the weekly measurements made by the Advanced Very High Resolution Radiometers (AVHRR) of NOAA satellites was used to investigate the structure and space-time variability of large-scale fronts in the Southern Indian Ocean (30-60degreesS and 20-150degreesE) during the period of 1997-1999. Monthly SST gradient maps provided an overall view of five basic fronts: the North and South Subtropical fronts (NSTF and SSTF, respectively), the Agulhas Front (AF), the Subantarctic Front (SAF), and the Polar Front (PF). Mean location of the fronts and associated SST and SST gradients with corresponding standard deviations were calculated at each 10degrees-spaced longitude. A double structure of the NSTF, SAF, and PF was demonstrated as well as the meandering of all fronts with amplitudes of 2-5degrees in latitude and wavelength of several degrees in longitude. Convergence and transient interaction between neighboring fronts appear to occur not only in the Crozet and Kerguelen regions, but in other regions as well. The mean locations and SST range of every front are in good agreement with previous work based on hydrographic surveys [J. Geophys. Res. 101 (1996) 3675], although some details are different (in particular, the larger zonal extent of the NSTF and the wider frontal SST ranges than previously observed). A good correspondence of the measurements made during two hydrographic surveys in the Kerguelen region (22 January-3 February 1999) and in the Tasmania region (3-22 March 1998) with satellite SST and SST gradient maps was found.

A N-15 tracer study was performed during an experimental transplantation trial of natural Posidonia oceanica cuttings. The experiment was done in situ at 17 m depth in the Revellata Bay (Calvi, NW Corsica, France). Despite high survival rates of transplants (>90%) after one year, the weight and the N content of transplants are significantly lower than those of reference plants. In absence of roots, the transplants are not able to meet their N requirement because, leaf uptake is insufficient to replenish the N lost during the natural leaf decay. This could constitute a major cause of long-term failure for transplantation experiments or natural recolonisation processes. The increase of the N-15 content in the roots shows that the plant re-allocates the nitrogen of one organ (i.e. leaves, rhizomes) to ensure the growth of another (i.e. roots). (C) 2003 Elsevier Ltd.

OBJECTIVES: To investigate the influence of transmembrane tumor necrosis factor (TNF)-alpha on adipose tissue development and insulin-mediated glucose metabolism. METHODS AND RESULTS: TNF-alpha and lymphotoxin-alpha-deficient mice expressing non-cleavable transmembrane TNF-alpha (Tg-tmTNF-alpha) and TNF-alpha/lymphotoxin-alpha double knockout (control) mice were kept on high-fat diet for 15 weeks. The food intake and feeding efficiency of Tg-tmTNF-alpha mice were significantly higher compared with control mice. At the end of the study, Tg-tmTNF-alpha mice had a significantly higher total body weight, as well as subcutaneous and gonadal adipose tissue mass. Histological analysis revealed that the expression of Tg-tmTNF-alpha resulted in a significantly increased adipocyte area and blood vessel density. Plasma leptin levels correlated positively with adipose tissue mass. The plasma levels of total cholesterol and HDL-cholesterol were significantly increased and LDL-cholesterol levels significantly decreased in Tg-tmTNF-alpha mice. Fasting blood glucose and plasma insulin levels were not different between the two genotypes and intraperitoneal glucose and insulin tolerance tests did not show significant differences. CONCLUSIONS: Transmembrane TNF-alpha enhances adipose tissue formation without altering insulin-mediated glucose metabolism in mice with nutritionally induced obesity. [less ▲]

Open reading frame SCO3571 of Streptomyces coelicolor encodes a protein of the cyclic AMP (cAMP) receptor protein (CRP) superfamily of regulatory proteins. A mutant revealed a dramatic defect in germination, followed by growth delay and earlier sporulation. This phenotype correlates with those of an adenylate cyclase (cya) mutant that cannot synthesize cAMP. This finding suggests that S. coelicolor may use a Cya-cAMP-CRP system to trigger complex physiological processes such as morphogenesis. [less ▲]

The manifestly artificial nature of film animation, the constant reinvention of the apparatus and its claims to alterity, all shape its own particular (and problematic) identity; most of all, however, these elements of animation interrogate cinema itself on historical and aesthetic levels. The study that reflects upon certain emblematic films demonstrates how the enterprise of film animation invites cinema to take stock of itself, to look back upon its history and to consider the possibilities of new developments in perspective and previously unexplored mobile arrangements in its time and space.

Barium (Ba), aluminium (Al), and zirconium (Zr) were measured in sediment trap material deployed at two margin settings of the NE Atlantic: the Bay of Biscaye at Goban Spur and the NW Iberian Margin. The Particulate Organic Carbon (POC)/Ba ratios of the trapped material in both margin environments are clearly higher compared to the open ocean. Although lateral advection of POC may partly explain these higher POC/Ba ratios for margin systems, it is clear that the yield of authigenic particulate Ba during organic matter degradation in the water column is lower in margin environments. In order to assess export production in margin settings we optimised transfer functions based on trapped Ba fluxes that were originally elaborated for open ocean settings. Calculations of export production based on trapped Ba flux and POC/Ba ratio were compared with calculations based on trapped POC flux only. Export production based on Ba flux show greater internal consistency amongst traps along the same mooring, suggesting that this approach has advantages over the one based on POC flux only. Estimated export productions are of the same order of magnitude as estimates of new production, but systematically fall short of the latter. This systematic discrepancy needs further investigation.
