Novel Approach to Switched Controller Design for Linear Continuous‐Time Systems
Authors: Veselý Vojtech , Ilka Adrian 
Published: October 2015

AbstractIn this paper, we study a novel approach to the design of an output feedback switched controller with an arbitrary switching algorithm for continuous‐time invariant systems that is described by a novel plant model as a gain‐scheduled plant using the multiple quadratic stability and quadratic stability approaches. In the proposed design procedure, there is no need to use the notion of the "dwell time". The obtained results are in the form of bilinear matrix inequalities (BMI). Numerical examples show that, in the proposed method, the design procedure is less conservative and gives more possibilities than that described in the papers published previously.
Characterization of continuous monoclonal antibody epitopes in the N‐terminus of Ro60

Published: October 2015

ABSTRACTOne of the major targets of the autoimmune response in the rheumatic autoimmune diseases, Systemic Lupus Erythematosus and Sjögrens Syndrome, is the protein Ro60. Ro60 is known to associate with small misfolded RNAs, and is involved in RNA quality control and in enhancing cell survival during cellular stress, e.g. after ultaviolet irradiation. In this study, six monoclonal antibodies to Ro60 were analyzed in order to identify antigenic regions and the nature of these. Preliminary analyses revealed that two of the antibodies recognized continuous epitopes, while the remaining antibodies most likely recognized conformational epitopes. The continuous epitopes of Ro60 were characterised by modified immunoassays employing resin‐bound peptides and free peptides. Peptide screenings located the epitopes to the N‐terminus of Ro60, and further analyses indicated that the epitopes of the monoclonal antibodies TROVE2 and SSI‐HYB 358‐02 were located to amino acids 8‐17 and 34‐49, respectively. Moreover, charged amino acids were found to be especially important for antibody reactivity, although antibody reactivity of the monoclonal antibody TROVE2 primarily was found to be epitope backbone‐dependent. © 2015 Wiley Periodicals, Inc.

Interleukin‐15‐transferred cytokine‐induced killer cells elevated anti‐tumor activity in a gastric tumor‐bearing nude mice model

Published: October 2015

AbstractGastric cancer is the second leading cause of cancer‐related mortality worldwide. Adoptive cell therapy (ACT) for gastric cancer is a novel therapy modality. However, the therapeutic effectiveness in vivo is still limited. The objective of this study was to assess the value of interleukin‐15 (IL‐15)‐transferred cytokine‐induced killer (CIK) cells in ACT for gastric cancer. IL‐15‐IRES‐TK retroviral vector was constructed and transferred into the CIK cells. A gastric tumor‐bearing nude mice model was constructed by subcutaneously injecting gastric cancer cells, BGC‐823. Gastric tumor‐bearing nude mice were randomly divided into three groups (five mice each group) and injected with physiological saline, CIK cells, and IL‐15‐IRES‐TK‐transfected CIK cells for 2 weeks, respectively. IL‐15‐IRES‐TK‐transferred CIK cells were prepared successfully and flow cytometry (FCM) analysis indicated that the transfection rate reached 85.7% after 5 days culture. In vivo experiment, we found that CIK cells retarded tumor growth by reducing tumor volume and tumor weight, as well as increasing tumor inhibition rate. Furthermore, IL‐15‐IRES‐TK‐transferred CIK cells showed a much stronger inhibition on tumor growth than CIK cells alone. Tumor morphology observation and growth indexes also showed that IL‐15‐transfected CIK cells had stronger cytotoxicity to tumor tissue than CIK cells. IL‐15‐IRES‐TK transfection could elevate the effects of CIK cells to gastric carcinoma. The engineered CIK cells carrying IL‐15‐IRES‐TK may be used in the ACT for gastric carcinoma, but prudent clinical trial is still indispensable.
Development of porcine tetraploid somatic cell nuclear transfer embryos is influenced by oocyte nuclei
Authors: Fu Bo , Liu Di , Ma Hong , Guo Zhen‐Hua , Wang Liang , Li Zhong‐Qiu , Peng Fu‐Gang , Bai Jing 
Published: October 2015

AbstractCloning efficiency in mammalian systems remains low because reprogramming of donor cells is frequently incomplete. Nuclear factors in the oocyte are removed by enucleation, and this removal may adversely affect reprogramming efficiency. Here, we investigated the role of porcine oocyte nuclear factors during reprogramming. We introduced somatic cell nuclei into intact MII oocytes to establish tetraploid somatic cell nuclear transfer (SCNT) embryos containing both somatic nuclei and oocyte nuclei. We then examined the influence of the oocyte nucleus on tetraploid SCNT embryo development by assessing characteristics including pronucleus formation, cleavage rate, and blastocyst formation. Overall, tetraploid SCNT embryos have a higher developmental competence than do standard diploid SCNT embryos. Therefore, we have established an embryonic model in which a fetal fibroblast nucleus and an oocyte metaphase II plate coexist. Tetraploid SCNT represents a new research platform that is potentially useful for examining interactions between donor nuclei and oocyte nuclei. This platform should facilitate further understanding of the roles played by nuclear factors during reprogramming.
Recent Advances in Organocatalytic Kinetic Resolution for the Synthesis of Functionalized Products
Authors: Gurubrahamam Ramani , Cheng You‐Song , Huang Wan‐Yun , Chen Kwunmin 
Published: October 2015

AbstractThis Minireview describes organocatalytic kinetic resolution (OCKR) that has evolved on the basis of using small organic catalysts through enamine/iminium ion, N‐heterocyclic carbene, and hydrogen‐bonding catalysis. The review includes the use of recent methodologies for which the evolution of OCKR mainly involves creating new stereogenic center(s) in functionalized products through the formation of a C−C, C−N, C−O, C−X, or C−S bond. The combination of OCKR with sequential reactions and its association with desymmetrization and dynamic kinetic resolution are also described.

AbstractThe principle aspects and constraints of the dynamics and kinetics of zeolite nucleation in hydrogel systems are analyzed on the basis of a model Na‐rich aluminosilicate system. A detailed time‐series EMT‐type zeolite crystallization study in the model hydrogel system was performed to elucidate the topological and temporal aspects of zeolite nucleation. A comprehensive set of analytical tools and methods was employed to analyze the gel evolution and complement the primary methods of transmission electron microscopy (TEM) and nuclear magnetic resonance (NMR) spectroscopy. TEM tomography reveals that the initial gel particles exhibit a core–shell structure. Zeolite nucleation is topologically limited to this shell structure and the kinetics of nucleation is controlled by the shell integrity. The induction period extends to the moment when the shell is consumed and the bulk solution can react with the core of the gel particles. These new findings, in particular the importance of the gel particle shell in zeolite nucleation, can be used to control the growth process and properties of zeolites formed in hydrogels.
Titania–Silica Materials for Enhanced Photocatalysis

Published: October 2015

AbstractMesoporous titania–organosilica nanoparticles comprised of anatase nanocrystals crosslinked with organosilica moieties have been prepared by direct co‐condensation of a titania precursor, tetrabuthylortotitanate (TBOT), with two organosilica precursors, 1,4‐bis(triethoxysilyl) benzene (BTEB) and 1,2‐bis(triethoxysilyl) ethane (BTEE), in mild conditions and in the absence of surfactant. These hybrid materials show both high surface areas (200–360 m2 g−1) and pore volumes (0.3 cm3 g−1) even after calcination, and excellent photoactivity in the degradation of rhodamine 6G and in the partial oxidation of propene under UV irradiation, especially after the calcination of the samples. During calcination, there is a change in the TiIV coordination and an increase in the content of SiOTi moieties in comparison with the uncalcined materials, which seems to be responsible for the enhanced photocatalytic activity of hybrid titania–silica materials as compared to both uncalcined samples and the control TiO2.
