Coordinated seasonal regulation of metabolic and reproductive hypothalamic peptides in the desert jerboa
Authors: Talbi Rajae , Klosen Paul , Laran‐Chich Marie‐Pierre , El Ouezzani Seloua , Simonneaux Valérie 
Published: April 2016

ABSTRACTJerboa (Jaculus orientalis) is a semi‐desert rodent displaying strong seasonal variations in biological functions in order to survive harsh conditions. When environmental conditions become unfavorable in early autumn, it shuts down its reproductive axis, increases its body weight, and finally hibernates. In spring, the jerboa displays opposite regulations, with a reactivation of reproduction and reduction in body weight. This study investigated how genes coding for different hypothalamic peptides involved in the central control of reproduction (Rfrp and Kiss1) and energy homeostasis (Pomc, Npy, and Somatostatin) are regulated according to seasons in male jerboas captured in the wild in spring or autumn. Remarkably, a coordinated increase in the mRNA level of Rfrp in the dorso/ventromedial hypothalamus and Kiss1, Pomc, and Somatostatin in the arcuate nucleus was observed in jerboas captured in spring as compared to autumn animals. Only Npy gene expression in the arcuate nucleus displayed no significant variations between the two seasons. These variations appear in line with the jerboa's seasonal physiology, since the spring increase in Rfrp and Kiss1 expression might be related to sexual reactivation, while the spring increase in genes encoding anorexigenic peptides, POMC, and somatostatin may account for the reduced body weight reported at this time of the year.

Iron Pentapyridyl Complexes as Molecular Water Oxidation Catalysts: Strong Influence of a Chloride Ligand and pH in Altering the Mechanism
Authors: Das Biswanath , Orthaber Andreas , Ott Sascha , Thapper Anders 
Published: April 2016

AbstractThe development of molecular water oxidation catalysts based on earth‐abundant, non‐noble metals is essential for artificial photosynthesis research. Iron, which is the most abundant transition metal in the earth's crust, is a prospective candidate for this purpose. Herein, we report two iron complexes based on the polypyridyl ligand Py5OH (Py5OH=pyridine‐2,6‐diylbis [di(pyridin‐2‐yl)methanol]) that can catalyse water oxidation to produce O2 in RuIII‐induced (at pH 8, highest turnover number (TON)=26.5; turnover frequency (TOF)=2.2 s−1), CeIV‐induced (at pH≈1.5 highest TON=16; TOF=0.75 s−1) and photo‐induced (at pH 8, highest TON=43.5; TOF=0.6 s−1) reactions. A chloride ligand in one of the iron complexes is shown to affect the activity strongly, improve stability and, thereby, the performance at pH 8 but it inhibits oxygen evolution at pH≈1.5. The observations are consistent with a change in mechanism for catalytic water oxidation with the Fe(Py5OH) complexes between acidic (CeIV) and near‐neutral pH (RuIII).
Elucidating Structural Characteristics of Biomass using Solution‐State 2 D NMR with a Mixture of Deuterated Dimethylsulfoxide and Hexamethylphosphoramide
Authors: Yoo Chang Geun , Pu Yunqiao , Li Mi , Ragauskas Arthur J. 
Published: April 2016

AbstractRecent developments of NMR methods for characterization of lignocellulosic biomass allow improved understanding of plant cell‐wall structures with minimal deconstruction and modification of biomass. This study introduces a new NMR solvent system composed of dimethylsulfoxide (DMSO‐d6) and hexamethylphosphoramide (HMPA‐d18). HMPA as a co‐solvent enhanced swelling and mobility of the biomass samples; thereby it allowed enhancing signals of NMR spectra. The structural information of biomass was successfully analyzed by the proposed NMR solvent system (DMSO‐d6/HMPA‐d18; 4:1, v/v) with different biomass. The proposed bi‐solvent system does not require derivatization or isolation of biomass, facilitating a facile sample preparation and involving with no signals overlapping with biomass peaks. It also allows analyzing biomass with a room‐temperature NMR probe instead of cryo‐probes, which are traditionally used for enhancing signal intensities.
Catalytic Conversion of Alcohols into Carboxylic Acid Salts in Water: Scope, Recycling, and Mechanistic Insights
Authors: Zhang Lei , Nguyen Duc Hanh , Raffa Guillaume , Trivelli Xavier , Capet Frédéric , Desset Simon , Paul Sébastien , Dumeignil Franck , Gauvin Régis M. 
Published: April 2016

AbstractThe catalytic conversion of alcohols into carboxylic acid salts in water was performed in the presence of ruthenium complexes supported by aliphatic PNP pincer ligands preformed or formed in situ. High activity toward a wide substrate scope was achieved with turnover number values of up to 4000. The air‐stable catalytic system can be recycled by using toluene as a catalyst‐immobilizing phase; the activity is maintained after five consecutive runs. Finally, mechanistic studies allowed some fundamental aspects related to water activation to be unveiled and to the mechanism postulated.
A novel active auxiliary circuit for efficiency enhancement integrated with synchronous buck converter
Authors: Panda Anup Kumar , Sarode Shiva , Tejavathu Ramesh 
Published: April 2016

SummaryIn this paper, a novel auxiliary circuit is introduced for the synchronous buck converter. This auxiliary circuit provides zero‐current, zero‐voltage switching conditions for the main and synchronous switches while providing zero‐current condition for the auxiliary switch and diodes. The proposed active auxiliary circuit integrated with synchronous buck converter that emanates to zero‐voltage transition (ZVT)–zero‐current transition (ZCT) pulse width‐modulated (PWM) synchronous buck converter is analyzed, and its operating modes are presented. The additional voltage and current stresses on main, synchronous and auxiliary switches get decimated because of the resonance of the auxiliary circuit that acts for a small segment of time in the proposed converter. The important design feature of soft‐switching converters is the placement of resonant components that mollifies the switching and conduction losses. With the advent of ZVT–ZCT switching, there is an increase in the switching frequency that declines the resonant component values in the converters and also constricts the switching losses. The characteristics of the proposed converter are verified with the simulation in the Power Sim (PSIM) software co‐simulated with MATLAB/SIMULINK environment and implemented experimentally.

Dynamic Behavior of Polydisperse Dust System in Cryogenic Gas Discharge Complex Plasmas
Authors: Antipov S. N. , Schepers L. P. T. , Vasiliev M. M. , Petrov O. F. 
Published: April 2016

AbstractComplex (dusty) plasmas of micron‐sized CeO2 polydisperse particles in dc glow discharges at 77 and ∼ 10 K were experimentally investigated. It was obtained that dust structure in cryogenic gas discharge plasma can be a mixture of two fractions (components) with completely different dust ordering and dynamics. We observed under some specific conditions that fast‐moving particles of one component diffuse through another component consisted of dust particles arranged in linear chains (strings). From experimental data analysis particle velocity distribution functions for each dust component were obtained. The possible nature of two‐component dust structure formation was discussed.
