Whether cholesterol lowering decreases risk of stroke has long remained unclear. Large epidemiological studies have found only weak links between cholesterol levels and stroke. Recent studies with statins, more potent cholesterol lowering agents, have now demonstrated significant reductions of stroke incidence and total mortality when administered for secondary prevention in patients with wide ranges of cholesterol values. It remains unknown if a statin is superior to others for the secondary prevention of stroke. [less ▲]

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 ▲]

Sr and Nd isotopic data from the anorthosite-mangerite-charnockite (AMC) suite of the Late-Sveconorwegian (ca. 0.93 Ga) Rogaland anorthosite province of SW Norway are discussed. The study focuses on new data obtained from three distinct rock occurrences: (1) primitive (=MgO-rich and K2O-poor)jotunites that represent the parental magmas of leuconorite and mafic plutons (Sr-87/Sr-86(0.93Ga) = ca. 0.704-0.707, epsilon(Nd)(0.93 Ga) = +3.6 down to +1.2); (2) evolved jotunites that differentiated from the primitive jotunites and constitute the starting components of dyke-scale fractionation trends (Sr-87/Sr-86(0.93Ga) = ca. 0.705-0.713, epsilon(Nd)(0.93 Ga) = +0.4 down to -2.0); and (3) felsic plutons (Sr-87/Sr-86(0.93Ga) = ca. 0.707-0.723, epsilon(Nd)(0.93Ga) = +1.4 down to -1.7). A comparison of the Sr and Nd isotopic compositions with available geochemical data (major and trace elements) is also made. Fractionation of the primitive to the evolved jotunites, below the intrusion level of the anorthosite province, is shown to have involved crustal contamination. A case of fractional crystallization and simultaneous contamination/assimilation is substantiated in the felsic cap of a layered intrusion (the Bjerkreim-Sokndal intrusion). It is further proposed that the Sr and Nd isotopic compositions of the various felsic occurrences result from fractional crystallization of primitive jotunitic melts, with or without contamination/assimilation; this strengthens the possibility for large volumes of silica-rich magmas to have been produced by fractionation, through evolved jotunites, of primitive jotunites. The entire range in Sr and Nd isotopic compositions of the Rogaland anorthosite province is interpreted as reflecting a mixing of crustal contaminants, having variable Sr-87/Sr-86(0.93Ga) ratios and (negative) epsilon(Nd)(0.93 Ga) values, with a more isotopically primitive source. The crustal end members of that mixing array are represented by moderatey to strongly LILE-enriched high-grade gneisses from the Pre-Sveconorwegian basement of southernmost Norway, that have a crustal history extending back to 1.5-1.9 Ga in the surroundings of the anorthosite province. The primitive end member is either an unusual LREE-depleted and Rb-enriched component, possibly corresponding to an originally depleted source subsequently modified by metasomatic fluids, or a more classical depleted component; it corresponds to a gabbronoritic rock of the deep crust, as shown by recent experimental data, with a quite short crustal residence time (<0.4-0.2 Ga). If that mafic end member is the lower granulitic crust itself, this would imply the presence in the deep continental crust of southwesternmost Norway of a crustal material strongly different from the 1.7- to 1.9-Gyr-old, moderately LILE-enriched component that is supposed to constitute the largest volume of the present deep continental crust in southern Norway.

The larval development of Myzostoma cirriferum is described by means of SEM, TEM, and cLSM. It is similar to that of other myzostomids and includes three stages: the protrochophore, the trochophore, and the metatrochophore. The protrochophore is a ball-shaped larva present in culture from 18-48 h after egg laying. It has no internal organs and its body is made of three cell types: covering cells and ciliated cells that are external and surrounded by a cuticle, and resting cells that fill the blastocoel. The trochophore is a pear-shaped larva that develops 20-72 h after egg laying; the body includes the same three cell types as the previous stage. The metatrochophore is a pear-shaped larva that develops between 40 h and 14 days and is characterized by the presence of two bundles of four chaetae. When fully developed, the metatrochophore has a digestive system (made of a pharynx, an esophagus, and a blind digestive pouch), two pairs of protonephridia, and a nervous system composed of a supraesophageal ganglion, circumesophageal connectives, and dorsal and ventral nerves. Metamorphosis generally occurs 7 days after egg laying. At that time, the metatrochophore loses its chaetae and becomes pleated ventrally. This ultrastructural analysis suggests that chaetae and the five ventral longitudinal nerve cords of M. cirriferum metatrochophores are homologous structures to those observed in some polychaete trochophores. Coupled with recent phylogenetic analyses, where the Myzostomida are placed outside the Annelida, homologies between myzostomid and polychaete larvae support the view that a trochophore appeared early during the spiralian evolution [less ▲]

Alternative oxidase (AOX) and uncoupling protein (UCP) are present simultaneously in tomato fruit mitochondria. In a previous work, it has been shown that protein expression and activity of these two energy-dissipating systems exhibit large variations during tomato fruit development and ripening on the vine. It has been suggested that AOX and UCP could be responsible for the respiration increase at the end of ripening and that the cytochrome pathway could be implicated in the climacteric respiratory burst before the onset of ripening. In this study, the use of tomato mutants that fail normal ripening because of deficiencies in ethylene perception or production as well as the treatment of one selected mutant with a chemical precursor of ethylene have revealed that the bioenergetics of tomato fruit development and ripening is under the control of this plant hormone. Indeed, the evolution pattern of bioenergetic features changes with the type of mutation and with the introduction of ethylene into an ethylene-synthesis-deficient tomato fruit mutant during its induced ripening.

A silvicultural decision support system (SDSS) has been developed for pure and even-aged larch stands (Larix sp.) in Walloon Region, where Larix seems to be a species with good prospects in a multifunctional management context. It main purposes are: (i) to predict the influence of silvicultural treatments on stand evolution and (ii) to help forest managers compare different scenarios according to preset goals. The SDSS comprises three modules designed for (i) larch growth prediction based on initial tree density, thinning regime and site index (scenarios building), (ii) assessment of a set of indicators describing scenarios and (iii) the comparison of scenarios according to appropriate calculated indicators (Multi-Criteria Decision Making or MCDM approach). Financial, technico-economic and ecological indicators are calculated in order to characterise wood production both qualitatively and quantitatively. One of them also tries to express a risk assessment (windthrow hazard). The MCDM method is based on partial aggregation (Electre III) and is used to compare scenarios according to the indicators. This SDSS is integrated in a user-friendly designed software “MGC_Larch” (Make Good Choice for Larch) that helps managers formulate, evaluate and compare different larch silvicultural scenarios according to their priority goals.

Since the late 1960s, The Sahel of West Africa is affected by a long-term drought and increasing human pressure on the environment leading to desertification processes. The Normalised Difference Vegetation Index (NDVI), calculated from satellite imagery, is a reliable index of the vegetation status as the vegetation response to rainfall is very strong in semiarid environments. This article presents the NDVI and rainfall evolution from 1981 to 1999 in nine locations along a north-south transect from north-western Niger to north-eastern Benin. These two parameters are then statistically analysed to identify breaks in the trends within the datasets. Over the 19 years analysed, it appears that five out of the nine locations have recorded a significant increase of rainfall, while only two presented a significant increase in NDVI. This dichotomy in observed trends may highlight the on-going slow processes of environmental degradation. [less ▲]
