A three-dimensional global model of the Earth system suitable for studying the long-term evolution of climate (LOVECLIM) has been recently developed. This model is made up of a coarse-resolution three-dimensional atmosphere-sea-ice-ocean model (ECBILT-CLIO), a dynamical model of the continental biosphere (VECODE), a comprehensive model of the oceanic carbon cycle (LOCH), and a high-resolution thermomechanical model of the Greenland and Antarctic ice sheets (AGISM). The atmospheric component has the big advantage that it has been simplified to a level that makes runs on a multi-century time-scale computationaly feasible, while still being capable of producing results that, on the whole, are comparable to those of atmospheric general circulation models. The performance of the coupled model is evaluated by performing ensemble simulations over the period 1500-2000 and by comparing the model results to available climate reconstructions. In these simulations, the following forcings are taken into consideration : the variations in solar irradiance, the volcanic activity, the anthropogenic emissions of CO2, and the changes in concentration of other greenhouse gases and sulphate aerosols resulting from human activities. In the future, the model will be used to investigate the evolution of climate and sea level over the third millennium. [less ▲]

Foliar discs (8 mm diameter) from expanding leaves of the middle part of vegetative shoots of Chrysanthemum morifolium Ramat raised in vitro were induced to form directly on specific media in vitro either roots or vegetative buds, or callus. The budding programme, on its specific medium, was deviated to callus formation by the addition of 2 mM beta-OH-E (beta-OH-ethyldrazine, an inhibitor of diamine oxidase). Conversely vegetative buds instead of callus were formed on the callus medium in the presence of 2 mM DFMO (difluoromethylornithine, an inhibitor of ornithine decarboxylase). Callus formation was characterized by high accumulation of free and particularly conjugated polyamines (PA), very low or undetectable activities of diamine- and polyamine oxidases, and transglutaminase. DFMO-deviation of callus initiation in favour of bud formation lowered the accumulation of PA and increased the activity of amine-oxidases. The high catabolism of PA in the organogenic (rooting, budding) programs was questioned as to its role in developmental processes. [less ▲]

The authors present the results of the first four months of the ESO-La Silla program of IR spectrophotometric monitoring of SN 1987A. The spectra show mainly hydrogen lines with their intensities increasing with time. The He I 1.083 μm line is also observed with a weak emission component and a strong absorption component. There are also several features whose nature is unclear. [less ▲]

Two siblings presented with encephalopathy, lactic acidosis, and hypocitrullinemia. Muscle and liver biopsies were considered for respiratory chain studies, but because of hypocitrullinemia, molecular analysis for maternally inherited Leigh syndrome was first performed, revealing in both siblings the mitochondrial DNA T8993G mutation (95% heteroplasmy), allowing to avoid tissue biopsies. Hypocitrullinemia, an occasional finding in mitochondrial diseases, has been specifically associated with T8993G mutation. However, only few patients have been reported, and the prevalence of hypocitrullinemia in 8993 mitochondrial DNA mutations is unknown. In a small series of 16 Leigh syndrome patients, sensitivity and specificity of hypocitrullinemia (< or = 12 micromol/L) for 8993 mitochondrial DNA mutations were 66% and 85%, respectively. Although studies in larger cohorts are necessary, we suggest considering T8993G mutation early in the diagnostic evaluation of infantile mitochondrial diseases with hypocitrullinemia, which minimizes the need for invasive procedures associated with a small but nonnegligible risk of complications and incorrect diagnosis.

The evolutionary history and geographical isolation of the Antarctic continent have produced a unique environment rich in endemic organisms. In many regions of Antarctica, cyanobacteria are the dominant phototrophs in both aquatic and terrestrial ecosystems. We have used microscopic and molecular approaches to examine the cyanobacterial diversity of biotopes at two inland continental Antarctic sites (80-82°S). These are amongst the most southerly locations where freshwater-related ecosystems are present. Results showed a low cyanobacterial diversity, with only 3-7 Operational Taxonomic Units (OTUs) per sample obtained by a combination of strain isolations, clone libraries and DGGE based on 16S rRNA genes. One OTU was potentially endemic to Antarctica and is present in several regions of the continent. Four OTUs were shared by the samples from Forlidas Pond and the surrounding terrestrial mats. Only one OTU, but no Internal Transcribed Spacer (ITS) sequences, was common to Forlidas Pond and Lundström Lake. The ITS sequences were shown to further discriminate different genotypes within the OTUs. ITS sequences from Antarctic locations appear more closely related to each other than to non-Antarctic sequences. Future research in inland continental Antarctica will shed more light on the geographical distribution and evolutionary isolation of cyanobacteria in these extreme habitats. [less ▲]

Hypoxia, a common feature of solid tumors, is a direct stress that triggers apoptosis in many cell types. Poor or irregular tumor vascularization also leads to a decreased drug diffusion and cancer cells distant from blood vessels (hypoxic cells) are exposed to low drug concentrations. In this report, we show that low daunomycin concentrations protect HCT116 colorectal cancer cells from hypoxia-induced apoptosis. While hypoxia induced p53 accumulation without expression of its responsive genes (bax and p21), daunomycin treatment restored p53 transactivation activity and cell cycle progression. We also demonstrated a role for Akt activation in daunomycin-induced protection through phosphorylation and inactivation of the Bcl-2 family proapoptotic factor Bad. Our data therefore suggest that chemotherapy could possibly, because of low concentrations in poorly vascularized tumors, protect cancer cells from hypoxia-induced cytotoxicity. [less ▲]
