The GHER 3D primitive equation model is implemented with threedifferent resolutions: a low resolution model (1/4Ž°) coveringthe whole Mediterranean Sea, an intermediate resolution model (1/20Ž°)of the Liguro-Provençal basin and a high resolution model (1/60Ž°)simulating the fine mesoscale structures in the Ligurian Sea. Boundaryconditions and the averaged fields (feedback) are exchanged betweentwo successive nesting levels. The model of the Ligurian Sea is also coupled with the assimilationpackage SESAM. It allows to assimilate satellite data and in situobservations using the local adaptative SEEK (Singular EvolutiveExtended Kalman) filter. Instead of evolving the error space by thenumerically expensive Lyapunov equation, a simplified algebraicequation depending on the misfit between observation and modelforecast is used. Starting from the 1st January 1998 the low and intermediate resolutionmodels are spun up for 18 months. The initial conditions for theLigurian Sea are interpolated from the intermediate resolutionmodel. The three models are then integrated until August 1999. Duringthis period AVHRR Sea Surface Temperature of the Ligurian Sea isassimilated. The results are validated by using CTD and XBT profilesof the SIRENA cruise from the SACLANT Center. In a second validation exercise,the AVHRR SST and model forecast %(not yet affected by the SST used for validation) are decomposed at different scalesusing a horizontal wavelet transform.The processes characteristic for each scale are isolated in the model and the SST images.The error statistics calculated on the wavelet amplitudes can thus be related to the ability of the model in forecasting the correspondingmarine processes. In a second validation exercise, the AVHRR SST and model forecast areboth decomposed at different scales using a horizontal wavelet transform.The characteristic processes for each scale are isolated in the modeland the SST images. The error statistics calculated on the waveletamplitudes can thus be related to the ability of the model inforecasting the corresponding marine processes. [less ▲]

Vascular endothelial growth factor (VEGF) is the major endothelial mitogen in central nervous system neoplasms and it is expressed in 64-95% of glioblastomas (GBMs). Tumour cells are the main source of VEGF in GBMs whereas VEGF receptors (VEGFR-1, its soluble form sVEGFR-1, VEGFR-2 and neuropilin-1) are expressed predominantly by endothelial cells. Infiltrating tumour cells and newly-formed capillaries progress through the extracellular matrix by local proteolysis involving matrix metalloproteinases (MMPs). Recent studies have shown that VEGF expression and bioavailability can be modulated by MMPs. We reported previously that the expression of MT1-MMP in human breast cancer cells was associated with an enhanced VEGF expression. We used quantitative RT-PCR, Western blot, gelatin zymography and immunohistochemistry to study the expression of VEGF, VEGFR-1, VEGFR-2, sVEGFR-1, neuropilin-1, MT1-MMP, MMP-2, MMP-9 and TIMP-2 in 20 human GBMs and 5 normal brains. The expression of these MMPs was markedly increased in most GBMs with excellent correlation between mRNA and protein levels; activated forms of MMP-2 and MMP-9 were present in 8/18 and 7/18 of GBMs. A majority of GBMs (17/20) also expressed high levels of VEGF, as previously reported, with strong correlation between VEGF and MT1-MMP gene expression levels, and double immunostaining showed that VEGF and MT1-MMP peptides co-localize in tumour and endothelial cells. Our results suggest that the interplay between metalloproteinases and VEGF previously described in experimental tumours may also be operative in human GBMs. Because of its dual ability to activate MMP-2 and to up-regulate VEGF, MT1-MMP might be of central importance in the growth of GBMs and represent an interesting target for anti-cancer treatments.

Urticaria is a transient eruption of erythematous or oedematous swelling of the dermis and is usually associated with itching which clinically is very easy to diagnose. However, it causes several etiological, pathophysiological and therapeutic problems. We will develop the acute and chronic urticaria as well as their different associations with systemic diseases. Some current data concerning chronic idiopathic autoimmune urticaria is reviewed. The management and therapeutics will be discussed. [less ▲]

The γ- and δ-lactones of less than 12 carbons constitute a group of compounds of great interest to the flavour industry. It is possible to produce some of these lactones through biotechnology. For instance, γ-decalactone can be obtained by biotransformation of methyl ricinoleate. Among the organisms used for this bioproduction, Yarrowia lipolytica is a yeast of choice. It is well adapted to growth on hydrophobic substrates, thanks to its efficient and numerous lipases, cytochrome P450, acylCoA oxidases and its ability to produce biosurfactants. Furthermore, genetic tools have been developed for its study. This review deals with the production of lactones by Y. lipolytica with special emphasis on the biotransformarion of methyl ricinoleate to γ-decalactone. When appropriate, information from the lipid metabolism of other yeast species is presented. [less ▲]

Precipitation of calcium carbonate by phytoplankton in the photic oceanic layer is an important process regulating the carbon cycling and the exchange Of CO2 at the ocean-atmosphere interface. Previous experiments have demonstrated that, under nutrient-sufficient conditions, doubling the partial pressure Of CO2 (pCO(2)) in seawater-a likely scenario for the end of the century-can significantly decrease both the rate of calcification by coccolithophorids and the ratio of inorganic to organic carbon production. The present work investigates the effects of high pCO(2) on calcification by the coccolithophore Emiliania huxleyi (Strain TW1) grown under nitrogen-limiting conditions, a situation that can also prevail in the ocean. Nitrogen limitation was achieved in NO3-limited continuous cultures renewed at the rate of 0.5 d(-1) and exposed to a saturating light level. pCO(2) was increased from 400 to 700 ppm and controlled by bubbling CO2-rich or CO2-free air into the cultures. The pCO(2) shift has a rapid effect on cell physiology that occurs within 2 cell divisions subsequent to the perturbation. Net calcification rate (C) decreased by 25% and, in contrast to previous studies with N-replete cultures, gross community production (GCP) and dark community respiration (DCR) also decreased. These results suggest that increasing pCO(2) has no noticeable effect on the calcification/photosynthesis ratio (C/P) when cells of E. huxleyi are NO3-limited. [less ▲]

To evaluate the effect of population-based cervical cancer screening on the occurrence of cervical cancer in The Netherlands, we investigated the incidence and survival of cervical cancer registered by a cancer registry in the Greater Amsterdam area. The incidence rate of squamous cell carcinoma decreased significantly from 9.2/100,000 women in 1988 to 5.9/100,000 in 2000 (P<0.001). The incidence rate of adenocarcinomas remained stable. After adjustment for age, stage and lymph node involvement, the relative risk of death was 1.6 times higher for patients with adenocarcinomas than for patients with squamous cell carcinoma (95% CI 1.2-2.1). The decreased survival was related to histological type, as the effect remained significant after correction for confounding factors. Over time, the prognosis of women with squamous cell carcinoma improved significantly. No significant change was observed for women diagnosed with adenocarcinoma. These results suggest that the screening programme in The Netherlands as executed in the Greater Amsterdam area is associated with a decreased incidence and increased survival of patients with squamous cell carcinoma, but fails to detect (pre)malignant lesions of adenocarcinoma. Since more than 92% of adenocarcinomas and its precursors contain high-risk HPV, adding HPV testing to cytologic screening might improve the present screening programme in detecting adenocarcinoma and its precursor lesions.
