An Enantio‐ and Diastereoselective Chemoenzymatic Synthesis of α‐Fluoro β‐Hydroxy Carboxylic Esters
Authors: Howard James K. , Müller Marion , Berry Alan , Nelson Adam 
Published: April 2016

AbstractThe trans‐o‐hydroxybenzylidene pyruvate aldolase‐catalysed reactions between fluoropyruvate and many (hetero)aromatic aldehydes yield aldol adducts without subsequent dehydration. Treatment of the reaction products with hydrogen peroxide yields the corresponding syn‐configured α‐fluoro β‐hydroxy carboxylic acids which have >98 % ee. The overall chemoenzymatic approach, in which fluoropyruvate serves as a fluoroacetate equivalent, may be exploited in the synthesis of polar building blocks and fragments with potential value in drug discovery.
Helium permeability of polymer materials as liners for composite overwrapped pressure vessels
Authors: Murray Brendan R. , Leen Sean B. , Semprimoschnig Christopher O. A. , Brádaigh Conchúr M. Ó 
Published: April 2016

ABSTRACTPolymers have been identified as replacement materials for metallic liners in composite overwrapped pressure vessels (COPVs) for future space launchers. PEEK, Nylon, and PVDF plastics formed from base powder grades have been permeability tested to determine their susceptibility to the diffusion of helium through flatwise panel cross sections. Permeability, diffusion, and solubility coefficients have been obtained for each material with PVDF and PA11 grades showing the lowest permeability coefficients and hence the best barrier properties to permeation. Crystallinity percentages and internal air void contents in the polymer samples have also been used to assess the differences in permeability between materials with an analysis of void dispersion effects given through X‐ray CT scanning techniques. The measured permeability coefficients have been used to assess the ability of all materials tested to act as a functional polymer liner in a standard COPV with final leak rates predicted based on liner thicknesses and weights. © 2016 Wiley Periodicals, Inc.

Published: April 2016

ABSTRACTIn order to control the impacts of blown sand in salty desert, in this article, the amphoteric emulsion, for the first time, was applied as an ecological sand‐fixing material. This study started from the synthesis of the poly{vinyl acetate‐dibutyl maleate‐acrylamide‐co‐3‐[N‐(2‐methacroyloylethyl)‐N, N‐dimethylammonio]‐propane sulfonate} [P(VAc‐DBM‐AM‐DMAPS)] copolymer emulsion. Then, the structures, composition, thermal property of the emulsion were characterized by 1H‐NMR, FTIR, and DSC, respectively. The basic properties of the emulsion and salt tolerance of the latex films were measured by using viscometer, dynamic light scattering, and laser Doppler electrophoresis also. And the sand‐fixing properties of the emulsion were evaluated. Finally, the influence of the emulsion on the growth of soil microbe and plants were discussed for understanding its ecological effect. The experimental results showed that the emulsion has been successfully synthesized and could be as an ecological sand‐fixing material. The related reason is that, first, the emulsion could significantly improve the compressive strength and water retaining; second, the emulsion had good thermal aging, freeze‐thaw stabilities and salt tolerance to withstand the changes in temperature and NaCl concentration of salty desert; third, the influence of the emulsion on the growth of plants and microbe of sand also showed a dependable ecological effect. © 2016 Wiley Periodicals, Inc.

Comparative Morphology and Histology of the Nasal Fossa in Four Mammals: Gray Squirrel, Bobcat, Coyote, and White‐Tailed Deer
Authors: Yee Karen K. , Craven Brent A. , Wysocki Charles J. , Van Valkenburgh Blaire 
Published: April 2016

ABSTRACTAlthough the anatomy of the nasal fossa is broadly similar among terrestrial mammals, differences are evident in the intricacies of nasal turbinal architecture, which varies from simple scroll‐like to complex branching forms, and in the extent of nonsensory and olfactory epithelium covering the turbinals. In this study, detailed morphological and immunohistochemical examinations and quantitative measurements of the turbinals and epithelial lining of the nasal fossa were conducted in an array of species that include the gray squirrel, bobcat, coyote, and white‐tailed deer. Results show that much more of the nose is lined with olfactory epithelium in the smallest species (gray squirrel) than in the larger species. In two species with similar body masses, bobcat and coyote, the foreshortened felid snout influences turbinal size and results in a decrease of olfactory epithelium on the ethmoturbinals relative to the longer canine snout. Ethmoturbinal surface area exceeds that of the maxilloturbinals in all four sampled animals, except the white‐tailed deer, in which the two are similar in size. Combining our results with published data from a broader array of mammalian noses, it is apparent that olfactory epithelial surface area is influenced by body mass, but is also affected by aspects of life history, such as diet and habitat, as well as skull morphology, itself a product of multiple compromises between various functions, such as feeding, vision, and cognition. The results of this study warrant further examination of other mammalian noses to broaden our evolutionary understanding of nasal fossa anatomy.

NN‐Based Output‐Feedback Control for Stochastic Nonlinear Systems with Unknown Control Directions
Authors: Min Hui‐Fang , Duan Na 
Published: April 2016

AbstractThis paper addresses the neural network‐based output‐feedback control problem for a class of stochastic nonlinear systems with unknown control directions. The restrictions on the drift and diffusion terms are removed and the conditions on unknown control directions are relaxed. By introducing a proper coordinate transformation, and combining dynamic surface control (DSC) technique with radial basis function neural network (RBF NN) approximation approach, we construct an adaptive output‐feedback controller to guarantee the closed‐loop system to be mean square semi‐globally uniformly ultimately bounded (M‐SGUUB). A simulation example demonstrates the effectiveness of the proposed scheme.
Identifying the differences in mechanisms of mycophenolic acid controlling fucose content of glycoproteins expressed in different CHO cell lines

Published: April 2016

ABSTRACTIn the biopharmaceutical industry, glycosylation is a critical quality attribute that can modulate the efficacy of a therapeutic glycoprotein. Obtaining a consistent glycoform profile is desired because molecular function can be defined by its carbohydrate structures. Specifically, the fucose content of oligosaccharides in glycoproteins is one of the most important attributes that can significantly affect antibody‐dependent cellular cytotoxicity (ADCC) activity. It is therefore important to understand the fucosylation pathway and be able to control fucosylation at the desired level to match predecessor materials in late stage and biosimilar programs. Several strategies were explored in this study and mycophenolic acid (MPA) was able to finely modulate the fucose content with the least undesired side effects. However, the response was significantly different between CHO cell lines of different lineages. Further experiments were then performed for a deeper understanding of the mechanism of fucosylation in different CHO cell lines. Results indicated that changes in the intracellular nucleotide involved in fucosylation pathway after MPA treatment are the main cause of the differences in fucosylation level response in different CHO cell lines. Differences in MPA metabolism in the various CHO cell lines directly resulted in different levels of afucosylation measured in antibodies produced by the CHO cell lines. Biotechnol.

UPLC–MS/MS assay for simultaneous determination of four compounds in rat plasma: application to pharmacokinetic study after oral administration of Caulis Spatholobi extract
Authors: Li Yubin , Song Tao , Jin Xing 
Published: April 2016

AbstractAn ultra‐performance liquid chromatography tandem mass spectrometry method was developed for the simultaneous determination of protocatechuic acid, catechin, gallocatechin and formononetin in rat plasma, with genkwanin as the internal standard in this study. Plasma samples were prepared by liquid–liquid extraction with ethyl acetate. The four components were separated on an Agilent Zorbax Eclipse Plus C18 column (2.1 × 50 mm, 1.8 μm) with the mobile phase consisting of water containing 0.05% formic acid and methanol (35:65, v/v), and detected by negative ion electrospray ionization in the selected reaction monitoring mode. The method was linear for all analytes over the investigated ranges, with all correlation coefficients >0.99. The validated lower limit of quantification was 0.5 ng/mL for protocatechuic acid, catechin, and gallocatechin and 0.8 ng/mL for formononetin. The intra‐ and inter‐day precisions (RSD, %) were <13.1%, and accuracy (RE, %) ranged from −13.8 to 9.9%. The mean absolute extraction recoveries of the analytes and internal standard from rat plasma were all >80.7%. The validated method was successfully applied for the first time to investigate the pharmacokinetics of four chemical ingredients after oral administration of Caulis Spatholobi Extract in rats.

Acetic acid removal from corn stover hydrolysate using ethyl acetate and the impact on Saccharomyces cerevisiae bioethanol fermentation
Authors: Aghazadeh Mahdieh , Ladisch Michael R. , Engelberth Abigail S. 
Published: April 2016

Acetic acid is introduced into cellulose conversion processes as a consequence of composition of lignocellulose feedstocks, causing significant inhibition of adapted, genetically modified and wild‐type S. cerevisiae in bioethanol fermentation. While adaptation or modification of yeast may reduce inhibition, the most effective approach is to remove the acetic acid prior to fermentation. This work addresses liquid–liquid extraction of acetic acid from biomass hydrolysate through a pathway that mitigates acetic acid inhibition while avoiding the negative effects of the extractant, which itself may exhibit inhibition. Candidate solvents were selected using simulation results from Aspen Plus™, based on their ability to extract acetic acid which was confirmed by experimentation. All solvents showed varying degrees of toxicity toward yeast, but the relative volatility of ethyl acetate enabled its use as simple vacuum evaporation could reduce small concentrations of aqueous ethyl acetate to minimally inhibitory levels. The toxicity threshold of ethyl acetate, in the presence of acetic acid, was found to be 10 g L−1. The fermentation was enhanced by extracting 90% of the acetic acid using ethyl acetate, followed by vacuum evaporation to remove 88% removal of residual ethyl acetate along with 10% of the broth. NRRL Y‐1546 yeast was used to demonstrate a 13% increase in concentration, 14% in ethanol specific production rate, and 11% ethanol yield. This study demonstrated that extraction of acetic acid with ethyl acetate followed by evaporative removal of ethyl acetate from the raffinate phase has potential to significantly enhance ethanol fermentation in a corn stover bioethanol facility. © 2016 American Institute of Chemical Engineers Biotechnol.

Published: April 2016

AbstractIn the paper, we present an online real‐time method for automatically transforming a basic locomotive motion to a desired motion of the same type, based on biomechanical results. Given an online request for a motion of a certain type with desired moving speed and turning angle, our method first extracts a basic motion of the same type from a motion graph, and then transforms it to achieve the desired moving speed and turning angle by exploiting the following biomechanical observations: contact‐driven center‐of‐mass control, anticipatory reorientation of upper body segments, moving speed adjustment, and whole‐body leaning. Exploiting these observations, we propose a simple but effective method to add physical and behavioral naturalness to the resulting locomotive motions without preprocessing. Through experiments, we show that our method enables a character to respond agilely to online user commands while efficiently generating walking, jogging, and running motions with a compact motion library. Our method can also deal with certain dynamical motions such as forward roll. Copyright © 2016 John Wiley & Sons, Ltd.

Authors: Wang Yanzhen , Serracino‐Inglott Ferdinand , Yi Xiaodong , Yang Xue‐Jun , Yuan Xue‐Feng 
Published: April 2016

AbstractThis paper presents an interactive simulation system for surgical procedures of endovascular aneurysm repair. It extracts anatomical structure of clinic interest from patient‐specific X‐ray computed tomography or magnetic resonance imaging data by image segmentation techniques, and then reconstructs surface triangular meshes of these anatomical structures from the volumetric data. The core of the system is an interactive computer‐based simulation module. It consists of a physical modeling unit, a collision detection unit, a visualization unit, and a control unit. The integration of these units together makes it possible for users to interact with the system in real time, performing virtual catheterization, angiography, and stent graft deployment under a user‐specified rendering mode. The prototype system can be used as a cost‐efficient tool for surgical planning with patient‐specific anatomical geometry and for practice of surgical procedures before actual operation.
