- Abstract
This paper discusses an innovative sensorless control for high performance drive trains with Doubly Fed Induction Machines (DFIM) and tendency to torsional oscillation, e.g. drive trains of wind turbines. The main goal of the presented closed loop control is the active damping of those torsional oscillations due to external load excitations for minimization of wear out and improvement of life-time and the overall reliability. The outstanding characteristic of the control algorithm is to work with highest performance without using sensors for rotation angle, rotational speed and shaft torque. Only the stator voltages and the phase currents of stator and rotor needs to be measured, which is done inherently and without high additional effort by the power converter for field oriented control of the DFIM. The performance of the sensorless control is presented by means of many measurement results. Zusammenfassung Der Beitrag bezieht sich auf ein sensorloses Regelverfahren für Antriebe mit doppeltgespeisten Asynchronmaschinen (DGASM) großer Leistung mit schwingungsfähigem mechanischem System, wie z.B. für Windenergieantriebe. Ziel des Verfahrens ist es, durch eine intelligente Regelung der DGASM die Torsionsschwingungen im mechanischen Antriebsstrang aktiv zu dämpfen, damit den Verschleiß zu vermindern und die Lebensdauer zu erhöhen. Das herausragende Merkmal des Regelverfahrens besteht darin, dass es ohne Sensoren für Drehwinkel, Drehzahlen und Drehzahlmomente auskommt. Gemessen werden nur die Ständerspannungen und die Ständerströme sowie die Läuferströme der DGASM. Das Leistungsvermögen des sensorlosen Regelverfahrens wird durch eine Vielzahl von Messergebnissen belegt.

AIMS To compare the efficacy and safety of lanoteplase, a single-bolus thrombolytic drug derived from alteplase tissue plasminogen activator, with the established accelerated alteplase regimen in patients presenting within 6 h of onset of ST elevation acute myocardial infarction. METHODS AND RESULTS 15,078 patients were recruited from 855 hospitals worldwide and randomized in a 2:1 ratio to receive either lanoteplase 120 KU. kg(-1)as a single intravenous bolus, or up to 100 mg accelerated alteplase given over 90 min. The primary end-point was all-cause mortality at 30 days and the hypothesis was that the two treatments would be equivalent. By 30 days, 6.61% of alteplase-treated patients and 6.75% lanoteplase-treated patients had died (relative risk 1.02). Total stroke occurred in 1.53% alteplase- and 1.87% lanoteplase-treated patients (ns); haemorrhagic stroke rates were 0.64% alteplase and 1.12% lanoteplase (P=0.004). The net clinical deficit of 30-day death or non-fatal disabling stroke was 7.0% and 7.2%, respectively. By 6 months, 8.8% of alteplase-treated patients and 8.7% of lanoteplase-treated patients had died. CONCLUSION Single-bolus weight-adjusted lanoteplase is an effective thrombolytic agent, equivalent to alteplase in terms of its impact on survival and with a comparable risk-benefit profile. The single-bolus regimen should shorten symptoms to treatment times and be especially convenient for emergency department or out-of-hospital administration.

- Abstract
Mammalian cells contain the cyclic pyrimidine nucleotides cCMP and cUMP. It is unknown whether these tentative new second messenger molecules occur in vivo. We used high performance liquid chromatography quadrupole tandem mass spectrometry to quantitate nucleoside 3',5'-cyclic monophosphates. cCMP was detected in all organs studied, most notably pancreas, spleen and the female reproductive system. cUMP was not detected in organs, probably due to the intrinsically low sensitivity of mass spectrometry to detect this molecule and organ matrix effects. Intratracheal infection of mice with recombinant Pseudomonas aeruginosa harboring the nucleotidyl cyclase toxin ExoY massively increased cUMP in lung. The identity of cCMP and cUMP in organs was confirmed by high performance liquid chromatography quadrupole time of flight mass spectrometry. cUMP also appeared in serum, urine and faeces following infection. Taken together, this report unequivocally shows for the first time that cCMP and cUMP occur in vivo., (Copyright © 2015 Elsevier Inc. All rights reserved.)

- Abstract
Adenosine 3',5'-cyclic monophosphate (cAMP) and guanosine 3',5'-cyclic monophosphate (cGMP) are well-established second messengers, whereas the physiological role of the cyclic pyrimidine nucleotides cytidine 3',5'-cyclic monophosphate (cCMP) and uridine 3',5'-cyclic monophosphate (cUMP) is poorly understood. Certain mammalian nucleotidyl cyclases (NCs) and bacterial NC toxins can generate cCMP and cUMP. Human HEK293 cells and rat B103 neuroblastoma cells are of neuronal origin and possess high basal concentrations of cCMP and cUMP that can be attributed to soluble adenylyl cyclase activity. These data prompted us to conduct a systematic analysis of basal nucleoside 3',5'-cyclic monophosphate (cNMP) concentrations across the tree of life. cCMP and cUMP were identified in many mammalian cell lines and primary cells. cNMP patterns varied broadly among cells, and in several systems, cCMP and cUMP concentrations were quite high. Prokaryotes, fungi, amoeba and invertebrates lacked cCMP and cUMP, whereas cAMP was found across the tree of life. High cCMP and cUMP concentrations were found in astrocytes. The distinct cNMP patterns support specific second messenger roles of cCMP and cUMP, specifically in astrocytes., (Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.)

- Abstract
In addition to the well-known second messengers cAMP and cGMP, mammalian cells contain the cyclic pyrimidine nucleotides cCMP and cUMP. The Pseudomonas aeruginosa toxin ExoY massively increases cGMP and cUMP in cells, whereas the Bordetella pertussis toxin CyaA increases cAMP and, to a lesser extent, cCMP. To mimic and dissect toxin effects, we synthesized cNMP-acetoxymethylesters as prodrugs. cNMP-AMs rapidly and effectively released the corresponding cNMP in cells. The combination of cGMP-AM plus cUMP-AM mimicked cytotoxicity of ExoY. cUMP-AM and cGMP-AM differentially activated gene expression. Certain cCMP and cUMP effects were independent of the known cNMP effectors protein kinases A and G and guanine nucleotide exchange factor Epac. In conclusion, cNMP-AMs are useful tools to mimic and dissect bacterial nucleotidyl cyclase toxin effects., (Copyright © 2014 Elsevier Inc. All rights reserved.)

- Abstract
In addition to the well known second messengers cAMP and cGMP, mammalian cells contain the cyclic pyrimidine nucleotides cCMP and cUMP. Soluble guanylyl cyclase and soluble adenylyl cyclase produce all four cNMPs. Several bacterial toxins exploit mammalian cyclic nucleotide signaling. The type III secretion protein ExoY from Pseudomonas aeruginosa induces severe lung damage and effectively produces cGMP. Here, we show that transfection of mammalian cells with ExoY or infection with ExoY-expressing P. aeruginosa not only massively increases cGMP but also cUMP levels. In contrast, the structurally related CyaA from Bordetella pertussis and edema factor from Bacillus anthracis exhibit a striking preference for cAMP increases. Thus, ExoY is a nucleotidyl cyclase with preference for cGMP and cUMP production. The differential effects of bacterial toxins on cNMP levels suggest that cUMP plays a distinct second messenger role., (Copyright © 2014 Elsevier Inc. All rights reserved.)

- Abstract
Adenosine 3', 5'-cyclic monophosphate (cAMP) and guanosine 3', 5'-cyclic monophosphate (cGMP) are well-studied second messengers that transmit extracellular signals into mammalian cells, with conserved functions in various other species such as Caenorhabditis elegans (C. elegans). cAMP is generated by adenylyl cyclases, and cGMP is generated by guanylyl cyclases, respectively. Studies using C. elegans have revealed additional roles for cGMP signaling in lifespan extension. For example, mutants lacking the function of a specific receptor-bound guanylyl cyclase, DAF-11, have an increased life expectancy. While the daf-11 phenotype has been attributed to reductions in intracellular cGMP concentrations, the actual content of cyclic nucleotides has not been biochemically determined in this system. Similar assumptions were made in studies using phosphodiesterase loss-of-function mutants or using adenylyl cyclase overexpressing mutants. In the present study, cyclic nucleotide regulation in C. elegans was studied by establishing a special nematode protocol for the simultaneous detection and quantitation of cyclic nucleotides. We also examined the influence of reactive oxygen species (ROS) on cyclic nucleotide metabolism and lifespan in C. elegans using highly specific HPLC-coupled tandem mass-spectrometry and behavioral assays. Here, we show that the relation between cGMP and survival is more complex than previously appreciated.
