On the determination of the solutions and maximum admissible power of the load flow equation via LMIS
Authors: Chesi G. , Hung Y. S. 
Published: July 2011

AbstractIt is well‐known that the load flow equation plays a key role in power systems. This paper investigates the load flow equation addressing two fundamental problems, namely the determination of the solutions of this equation in a given region of interest, and the computation of the maximum admissible power for which this equation has a solution in such a region. For the first problem, it is shown that the sought solutions can be computed by solving an eigenvalue problem (EVP), i.e. a convex optimization problem with linear matrix inequality (LMI) constraints, and by looking for vectors with special structure into a linear subspace. For the second problem, it is shown that an upper bound of the sought maximum admissible power can be found by solving another EVP, moreover a sufficient and necessary condition for establishing the tightness of the found upper bound is provided. The proposed methodology is illustrated by some numerical examples.Copyright © 2011 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society
Are the Ro RNP‐associated Y RNAs concealing microRNAs? Y RNA‐derived miRNAs may be involved in autoimmunity
Authors: Verhagen Anja P. M. , Pruijn Ger J. M. 
Published: July 2011

AbstractHere we discuss the hypothesis that the RNA components of the Ro ribonucleoproteins (RNPs), the Y RNAs, can be processed into microRNAs (miRNAs). Although Ro RNPs, whose main protein components Ro60 and La are targeted by the immune system in several autoimmune diseases, were discovered many years ago, their function is still poorly understood. Indeed, recent data show that miRNA‐sized small RNAs can be generated from Y RNAs. This hypothesis leads also to a model in which Ro60 acts as a modulator in the Y RNA‐derived miRNA biogenesis pathway. The implications of these Y RNA‐derived miRNAs, which may be specifically produced under pathological circumstances such as in autoimmunity or during viral infections, for the enigmatic function of Ro RNPs are discussed.
A highly selective fluorescent probe for pyrophosphate detection in aqueous solutions

Published: July 2011

ABSTRACTA novel and simple fluorescence enhancement method is introduced for selective pyrophosphate (PPi) sensing in an aqueous solution. The method is based on a 1:1 metal complex formation between tris(8‐hydroxyquinoline‐5‐sulphonate) thulium(III) [Tm(QS)3] and PPi ion. The linear response covers a concentration range of 1.6 × 10−7–1.0 × 10−5 mol/L PPi and the detection limit is 2.3 × 10−8 mol/L. The association constant of Tm(QS)3–PPi complex was calculated as 2.6 × 105 mol/L. Tm(QS)3 shows a selective and sensitive fluorescence enhancement toward PPi ion in comparion with I3−, NO3−, CN−, CO32−, Br−, Cl−, F−, H2PO4− and SO42−, which is attributed to higher stability of the inorganic complex between pyrophosphate ion and Tm(QS)3.

Binding Energetics of Ferredoxin‐NADP+ Reductase with Ferredoxin and Its Relation to Function
Authors: Lee Young‐Ho , Ikegami Takahisa , Standley Daron M. , Sakurai Kazumasa , Hase Toshiharu , Goto Yuji 
Published: July 2011

AbstractTo obtain insight into the motional features of proteins for enzymatic function, we studied binding reactions between ferredoxin‐NADP+ reductase (FNR) and ferredoxin (Fd) using isothermal titration calorimetry and NMR‐based magnetic relaxation and hydrogen/deuterium exchange (HDex). Fd–FNR binding was accompanied by endothermic reactions and driven by the entropy gain. Component‐wise analysis of the net entropy change revealed that increases in the conformational entropy of the Fd–FNR complex contributed largely to stabilizing the complex. Intriguingly, analyses of magnetic relaxation and HDex rates with X‐ray B factor implied that Fd binding led to both structural stiffening and softening of FNR. Enhanced FNR backbone fluctuations suggest favorable contributions to the net conformational entropy. Fd‐bound FNR further showed that relatively large‐scale motions of the C terminus, a gatekeeper for interactions of NADP+(H), were quenched in the closed form, thereby facilitating exit of NADP+(H). This can provide a first dynamic structure‐based explanation for the negative cooperativity between Fd and NADP+(H) via FNR.
