Diabetic nephropathy is one of the leading causes of end-stage renal failure in western countries. This disease develops over several years. Early stages, if they are detected in time, can lead to preventive treatment at a moment when the disease is still reversible. This paper reviews the main primary and secondary preventive measures that have been proven efficacious. Those are essentially the optimal treatment of hyperglycaemia and hypertension, and probably the use of agents that specifically block the renin-angiotensin axis. We briefly discuss the results of the main studies that have led to those conclusions. [less ▲]

Wormhole-like mesoporous walls are observed within macroporous metal oxides that were synthesized in one step using nonionic alkyl-PEO surfactants as templates. The uniform macropores have a funnel-like shape (tapered towards the center) and are arranged parallel to each other and perpendicular to the tangent of the particle surface (see micrographs). The mesochannels are interconnected with funnel-like macrochannels. [less ▲]

We describe the molecular mechanisms of action of nicotine and delta 9-tetrahydrocannabinol, the most potent component of cannabis. Like other drugs of abuse, these compounds enhance dopamine release in a precise area of the limbic system when administered acutely. It has recently been shown that the cannabinoid receptors on which delta 9-tetrahydrocannabinol acts are also activated by endogenous ligands such as anandamide. This unconventional neurotransmitter appears to have important physiological effects in the central nervous system. Both preclinical and clinical evidence suggests that nicotine is more addictive than delta 9-tetrahydrocannabinol. However, the intimate interactions that exist between cannabinoid and opioid systems within the brain suggest that cannabinoids should not be considered as harmless drugs of abuse. [less ▲]

The poplar wood has been known and used for a very long time. However, it has been systematically studied only since the end of the second world war, probably because of its reduced presence in the forests. An intuitive use of the poplar existed already among our ancestors but the study of its macro- and microscopic properties has directed it to more specific uses. The comprehension of its physical and mechanical properties led to a better knowledge of its behaviour during the various phases of transformation and helped to forecast its evolution when used, taking into account its natural longevity and the eventual presence of defects appearing on the trees and in the wood. In current poplar cultivation, all these characteristics must be considered to fix the criteria of selection taking into account the quality of the wood and its capability for transformation. The clonal production of poplars offers the transformation industry a raw material relatively homogenous in terms of technological properties, form and dimension. Nevertheless, each cultivar can differ in one or several of its characteristics. [less ▲]

Modelling of seagrasses can be an effective tool to assess factors regulating their growth. Growth and production model of Posidonia oceanica, the dominant submerged aquatic macrophyte occurring in the Bay of Calvi (Corsica, Ligurian Sea, Northwestern (NW) Mediterranean) was developed. The state variables are the above- and below-ground biomass of P oceanica, the epiphyte biomass, and the internal nitrogen concentration of the whole plant. Light intensity and water temperature are the forcing variables. The model reproduces successfully seasonal growth and production for each variable at various depths (10, 20 and 30 m). The model can simulate also a number of consecutive years. Sensitivity analysis of model's parameters showed that the maximum nitrogen quota n(max) rate is the most sensitive parameter in this model. The results simulations imply that light intensity is one of the most important abiotic factors, the diminution of which can cause an important reduction in seagrass density. (C) 2003 Elsevier B.V.

Because symptoms associated with hypomagnesia are highly aspecific, this ionic abnormality is rarely searched for although it could be present in as much as 20 % of the population. The mode of correction (oral or intravenous) depends on the etiology, severity and clinical consequences of hypomagnesemia. Significant hypermagnesemia only occurs in the presence of renal insufficiency and/or acute excess administration, mainly by the intravenous route. If interruption of administration does not suffice, renal dialysis might become necessary to quickly correct the magnesemium serum levels. [less ▲]

We demonstrate that a new emerging technique, two-colour sum-frequency generation (SFG) spectroscopy, can be used to probe the molecular electronic properties of self-assembled monolayers (SAMs). In the CH spectral range (2800–3200 cm-1), we show that the sum-frequency generation signal of a porphyrin alkanethiol derivative adsorbed on Pt(1 1 1) reaches a maximum intensity at ~435 nm SFG wavelength. This wavelength corresponds to the porphyrin moiety specific p–p*$ molecular electronic transition which is called the Soret or B band. This resonant behaviour is not observed for 1-dodecanethiol SAMs, which are devoid of molecular electronic transition in the investigated visible spectral range. [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.
