Introduction; Currently, the majority of countries tries to reduce their dependency on fossil fuels by the introduction of renewable resources in their energy systems. In the following the relatively small Luxembourgish electricity system is analysed (0.55 Mio Inhabitants). Current power-system-models mainly focus on larger systems, due to the unavailability of specific consumption-data. Prices and effects on the Luxembourgish power system of different supply scenarios for rural-private households are analysed. Methodology; A linear optimisation for the minimum-cost of the power-supply of all villages with the following renewable energy resources: wind- (max.100kW), solar-PV- and hydrokinetic-power is made. The electricity-demand scales with the number of inhabitants and agricultural-consumers. The wind-power-potential differs with the location of the village. The solar-radiation is assumed to be the equal over the country, due to the small size of approximately 80 by 50 km. The hydrokinetic turbines complete the supply where a village is located close to a river. Results; The minimum cost of the specific village power-supply is the result of the optimization. The installation- and maintenance-cost of each renewable technology are considered. The whole number of rural Luxembourgish private households is considered and their power contribution to the system is estimated for different renewable energy supply scenarios, namely from 11,8% to 100% renewable-energy-scenarios. For each scenario the power exchanged from the village to the grid is calculated in 15-min-steps for 9-years, the amount differs widely with the amount of applied technologies. Discussion; Due to the high share of imported electricity of about 80% in the recent years, every consideration of national power generation does not harm the supply security. Conclusion; Luxembourg is a good model country to analyse the high share of distributed, renewable generators, due to its structure of rural and civic regions and their effects on a central European region with a high electricity consumption.

Mutations in alpha-synuclein have been identified in some rare families with autosomal dominant Parkinson's disease (PD). The synuclein gene family shares physical and functional homology with 14-3-3 proteins and binds to 14-3-3 proteins and to its ligands. We therefore investigated whether 14-3-3 proteins are also involved in the pathogenesis of PD. Here we demonstrate that 14-3-3 proteins are colocalized with Lewy bodies in PD. We investigated the 14-3-3 eta (YWHAH) gene by mutation analysis and association studies as it maps to human chromosome 22q12.1-q13.1, a region which has been recently implicated in PD and carried out immunohistochemical studies of Lewy bodies with two different 14-3-3 eta antibodies. In 358 sporadic and familial PD patients, disease causing mutations were not identified. Furthermore, association studies with intragenic polymorphisms do not provide evidence for an involvement of 14-3-3 eta in the pathogenesis of PD. In accordance with these findings, there was no staining of substantia nigra Lewy bodies with antibodies specific for the 14-3-3 eta subunit. [less ▲]

High throughput sequencing of 16S/18S rRNA gene is becoming an indispensable tool to explore microbial community ecology. To date, most of the studies using next generation amplicon sequencing of microorganisms involved in the anaerobic digestion process (AD) are based on the 454 pyrosequencing. However, the cost per read obtained with the Illumina technology is currently less than 1/100 of that for the 454 pyrosequencing, thus enabling throughout sequencing and larger number of samples to be analysed per study (e.g. given the current Miseq output, around 100 000 reads per sample can be expected for a pool of 96 libraries). Moreover, the Illumina technology is less biased by the GC content of the template and currently allows for a relatively long sequence read of 600 bp (2 x 300bp). This consideration is particularly important, since longer sequences permit for more accurate assignment to a taxonomic group. Here, we designed and optimized an Illumina–based 16S rRNA amplicon approach for a high throughput characterization of microbial communities from different AD. [less ▲]

The cardioprotective effects of estrogens are clearly established. However, the underlying mechanisms are poorly understood. Because programmed cell death (apoptosis) probably contributes to the loss of cardiac myocytes in heart failure and because estrogens prevent apoptosis in breast cancer cells, we investigated whether the loss of cardiac myocytes by programmed cell death could be prevented by physiological doses of 17beta-estradiol. Apoptosis of cultured cardiac myocytes was induced by staurosporine. 17beta-estradiol (10 nM) had an antiapoptotic effect as determined by morphological analysis, vital staining using the Hoechst dye 33342 and terminal transferase dUTP nick-end labeling (TUNEL). As a potential mechanism for the antiapoptotic effect of 17beta-estradiol we found a reduced activity of the ICE-like protease caspase-3 in hormone-treated myocytes. Furthermore, inhibition of apoptosis by estradiol was associated with a reduced activity of NF-kappaB transcription factors, particularly p65/RelA and p50. To our knowledge, these data provide the first indication that 17beta-estradiol in physiological concentrations inhibits apoptosis in cardiac myocytes. The antiapoptotic effect of estrogens might contribute to the known cardioprotective effect of estrogens and provides a starting point for the development of future treatment options. [less ▲]
