Aims/Hypothesis: Glitazones are powerful insulin sensitisers prescribed for the treatment of type 2 diabetes. Their use is, however, associated with fluid retention and an increased risk of congestive heart failure. We previously demonstrated that pioglitazone increases proximal sodium reabsorption in healthy volunteers. This study examines the effects of pioglitazone on renal sodium handling in individuals prone to insulin resistance, i.e. those with diabetes and/or hypertension. Methods: In this double-blind randomised placebo-controlled four-way crossover study, we examined the effects of pioglitazone (45 mg daily during 6 weeks) or placebo on renal, systemic and hormonal responses to changes in sodium intake in 16 individuals, eight with type 2 diabetes and eight with hypertension. Results: Pioglitazone was associated with a rapid increase in body weight and an increase in diurnal proximal sodium reabsorption, without any change in renal haemodynamics or in the modulation of the renin-angiotensin aldosterone system to changes in salt intake. A compensatory increase in brain natriuretic peptide levels was observed. In spite of sodium retention, pioglitazone dissociated the blood-pressure response to salt and abolished salt sensitivity in salt-sensitive individuals. Conclusions/Interpretation: Pioglitazone increases diurnal proximal sodium retention in diabetic and hypertensive individuals. These effects cause fluid retention and may contribute to the increased incidence of congestive heart failure with glitazones.

We all know that too much salt is bad for our hearts. But the fact is that even if you completely stopped adding salt to your food you'd still be 100% over the recommended daily allowance. How? Because between 65% and 70% of the salt we actually eat comes from processed food, fast food, and canteen and restaurant food – so you're seasoning your heart without realising it. So what can you do?

We all know that too much salt is bad for our hearts. But what can you do to cut down? Between 65% and 70% of the salt we eat comes from processed food, fast food, and canteen and restaurant food; so as well as reducing the amount of salt that you add to food, it's especially important to cut down on the amount of salt you get from processed food. Getting to know your way around nutrition labels will go a long way to help you do this.

PURPOSE OF REVIEW: NEDD4-2 is an ubiquitin-protein ligase that was originally identified as an interactor of the epithelial Na+ channel (ENaC); this interaction is defective in Liddle's syndrome, causing elevated ENaC activity and salt-sensitive hypertension. In this review we aim to highlight progress achieved in recent years demonstrating that NEDD4-2 is involved in the control of Na+ transporters that are different from ENaC, but which also play a role in salt-sensitive hypertension. RECENT FINDINGS: It has been shown that NEDD4-2 interacts with ubiquitylates and negatively regulates the thiazide-sensitive NCC (Na+,Cl- -cotransporter), both in vitro and in vivo in inducible, nephron-specific Nedd4-2 knockout mice. Moreover, evidence has been provided that NEDD4-2 is also involved in the regulation of human NHE3 (Na+,H+-exchanger 3) and NKCC2 (Na+,K+,2Cl- -cotransporter 2). SUMMARY: The emerging role of NEDD4-2 in the regulation of different Na+ transporters along the nephron and the identification of human polymorphisms in the NEDD4-2 gene (Nedd4L) related to salt-sensitive hypertension makes this ubiquitin-protein ligase an interesting target for the development of antihypertensive drugs.

Determining groundwater flow paths of infiltrated river water is necessary for studying biochemical processes in the riparian zone, but their characterization is complicated by strong temporal and spatial heterogeneity. We investigated to what extent repeat 3D surface electrical resistance tomography (ERT) can be used to monitor transport of a salt-tracer plume under close to natural gradient conditions. The aim is to estimate groundwater flow velocities and pathways at a site located within a riparian groundwater system adjacent to the perialpine Thur River in northeastern Switzerland. Our ERT time-lapse images provide constraints on the plume's shape, flow direction, and velocity. These images allow the movement of the plume to be followed for 35 m. Although the hydraulic gradient is only 1.43 parts per thousand, the ERT time-lapse images demonstrate that the plume's center of mass and its front propagate with velocities of 2x10(-4) m/s and 5x10(-4) m/s, respectively. These velocities are compatible with groundwater resistivity monitoring data in two observation wells 5 m from the injection well. Five additional sensors in the 5-30 m distance range did not detect the plume. Comparison of the ERT time-lapse images with a groundwater transport model and time-lapse inversions of synthetic ERT data indicate that the movement of the plume can be described for the first 6 h after injection by a uniform transport model. Subsurface heterogeneity causes a change of the plume's direction and velocity at later times. Our results demonstrate the effectiveness of using time-lapse 3D surface ERT to monitor flow pathways in a challenging perialpine environment over larger scales than is practically possible with crosshole 3D ERT.

L¿objectiu del projecte es estudiar el que és i el que no és un sistema d¿informació geogràfica,conèixer la tecnologia associada a aquests sistemes, així com el tipus i format de les dades que fan servir. Tanmateix, l¿estudi no és només teòric i, per conèixer els mecanismes de automatització que ofereix GeoMedia, s¿implementa una petita eina de gestió de vèrtexs geodèsics centrada al territori de Catalunya que fa servir Oracle, com a gestor de bases de dades.

Anopheles aquasalis larvae are salt water tolerant, preferring concentrations between 10 and 20 parts per thousand (ppt). The larvicidal efficacy of two formulations of Bacillus thuringiensis var. israelensis (Vectobac-12AS® and Bactivec®), was investigated against An. aquasalis at salinities of 0, 10, and 20 ppt. A probit analysis was used to calculate the lethal concentrations (LC50 and LC95) for each product at each salinity. The LC50 and LC95 were higher for Bactivec® than Vectobac-12AS®, and for Bactivec®, the LC50 and LC95 increased with salinity. Vectobac-12AS® should thus be preferred to Bactivec® for An. aquasalis control, especially in saline breeding habitats.

Aquest treball s'estructura en tres parts. En la primera hi ha el projecte de treball. La segona part vol reflectir tot el marc conceptual elaborat i reelaborat amb profunditat entorn de la recerca, el qual és necessari per a estructurar, entendre i autoavaluar-la. El marc conceptual se centra bàsicament en tres aspectes: en primer lloc, el mètode de recerca emprat en la recerca PIC a les escoles; en segon lloc, l'evolució de les tecnologies en l'ensenyament paral·lelament a la mateixa concepció de l'ensenyament-aprenentatge, i, com a conseqüència dels dos anteriors, finalment, s'hi analitza l'evolució del concepte d'alfabetització, concretant l'estudi en l'alfabetització digital, com també la possibilitat ampliada per a les TIC de fomentar l'aprenentatge col·laboratiu. La tercera part del treball analitza la funció social de l'escola en la societat del coneixement.

L'arribada a Catalunya de població immigrant en edat escolar ha estat un repte per al nostre sistema educatiu. La resposta que s'ha donat a aquest repte amb les aules d'acollida és analitzada en aquest document. En primer lloc, s'explica quina és la situació actual de l'alumnat català i quines han estat les accions anteriors per a atendre immigrants. En segon lloc, s'estudia el cas del Canadà. Finalment, es torna a mirar cap a Catalunya i el cas concret d'un institut del Vallès Occidental. S'hi fa una avaluació del primer any de posada en marxa de les aules d'acollida i s'hi especifiquen millores que cal portar a terme per a optimitzar el recurs.
