Ivabradine HCL‐Loaded Polymeric Microspheres Consisting of Ethyl Cellulose and Eudragit FS30D for Controlled Drug Release
Authors: Majeed Abdul , Ranjha Nazar Muhammad 
Published: May 2016

AbstractIn this study, microspheres of Eudragit FS30D and ethyl cellulose (EC) were prepared by oil‐in‐oil (O/O) solvent evaporation method with the addition of 1% span 80 as emulsifier. Ivabradine HCl (IBH) was encapsulated into microspheres by the in situ method. The resultant microspheres were characterized with respect to drug loading, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X‐ray diffractometry (XRD), differential scanning calorimetry (DSC), and release behavior. Chemical stability of IBH encapsulated into prepared microspheres was confirmed by FTIR, DSC, and XRD analysis. SEM images showed spherical microspheres. Maximum percentage entrapment efficiency of ivabradine was found to be 45.1% and percentage yield was about 71.66%. Maximum in vitro drug release was 95.9% for the pH 7.5 buffer solution which demonstrated the pH sensitivity of microspheres. Cumulative drug release data were analyzed using different kinetic models. Korsmeyer–Peppas equation was used to determine the value of n which follows non‐Fickian diffusion.
Synthesis of Optically Active Polystyrene Catalyzed by Monophosphine Pd Complexes
Authors: Jouffroy Matthieu , Armspach Dominique , Matt Dominique , Osakada Kohtaro , Takeuchi Daisuke 
Published: May 2016

AbstractCationic PdII monophosphine complexes derived from α‐ and β‐cyclodextrins (CDs) promote the homopolymerization of styrene under carbon monoxide pressure. Although reversible CO coordination takes place under catalytic conditions according to 13C NMR studies with 13C‐enriched CO, both complexes catalyze the formation of CO‐free styrene polymers. These macromolecules display optical activity as a result of the presence of stereoregular sequences within the overall atactic polymer.
Charged groups synergically enhance protein imprinting in amphoteric polyacrylamide cryogels
Authors: Yang Chun , Zhou Xing‐Lu , Liu Ya‐Ru , Wang Jian , Tian Li‐Li , Zhang Yan , Hu Xia‐Ya 
Published: May 2016

ABSTRACTProteins are amphoteric biopolymers with unevenly charged exterior surfaces. Taking this point fully into account could accomplish ingenious recognition systems for the biological macromolecues. Molecularly imprinted polymers (MIPs) are good tools to study the interactions between polymeric matrices and template molecules. Here different protein imprinted cryogels were prepared. Imprinting factors (IFs) were determined with bovine serum albumin (BSA) as the template. The IF of the polymeric cryogel made from only acrylamide (AM) and N,N′‐methylenebisacrylamide (BisAM) is about 1.38. The introduction of charged monomers, either acrylic acid or diallylamine, would increase IFs obviously. One of the basic cryogels gave the maximum IF (about 2.0) of that type. As both acrylic acid and diallylamine were involved, IFs were further increased. An amphoteric cryogel with a suitable acid‐base ratio gave a high IF of about 3.7. Whatever used alone or both, too many added acidic or basic monomers resulted in IF reduction. Taking full advantage of charged groups in MIPs could be a good way to manipulate protein–polymer interactions. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43851.
The Quadratojugal of Eryops studied by computed tomography and the morphological variability of foramina and canals in the quadratojugal of basal tetrapods
Authors: Čerňanský Andrej , Witzmann Florian , Klembara Jozef , van Heteren Anneke H. 
Published: May 2016

ABSTRACTWith respect to its large size and abundance, Eryops is an important representative of Permo‐Carboniferous basal tetrapods and one of the best‐known large temnospondyl amphibians of this period. This taxon forms a significant component of the Early Permian tetrapod fauna of Texas and New Mexico and here we describe a new record of skull remains, the first one from Brushy Creek (30 km northeast of Seymour) in Texas (Petrolia Formation, Wichita Group; Lower Permian – lower Artinskian). Our material, found in 2015, consists of a left nasal, a jaw fragment (premaxilla or maxilla), left quadratojugal fragments, and a partial left mandible. We used computed tomography methods (micro‐CT) for imaging both internal and external structures, for the first time, for Eryops. The quadratojugal presented here is exceptional compared to all known basal tetrapods in having four different internal foramina. CT data show that these foramina are interconnected by canals within the bone. This indicates that the morphology of the foramina and the course of the canals in the quadratojugal of basal tetrapods are more variable than hitherto thought.

DNA Triplexes‐Guided Assembly of G‐Quadruplexes for Constructing Label‐free Fluorescent Logic Gates
Authors: Xu Lijun , Hong Shanni , Shen Xiaoqiang , Zhou Lu , Wang Jine , Zhang Jianye , Pei Renjun 
Published: May 2016

AbstractAssembly of G‐quadruplexes guided by DNA triplexes in a controlled manner is achieved for the first time. The folding of triplex sequences in acidic conditions brings two separated guanine‐rich sequences together and subsequently a G‐quadruplex structure is formed in the presence of K+. Based on this novel platform, label‐free fluorescent logic gates, such as AND, INHIBIT, and NOR, are constructed with ions as input and the fluorescence of a G‐quadruplex‐specific fluorescent probe NMM as output.

Published: May 2016

BackgroundConcerns about solvent releases from a microelectronics/business machine manufacturing facility in upstate New York led to interest in the health of former workers, including this investigation of birth defects in children of male and female employees.MethodsChildren born 1983 to 2001 to facility employees were enumerated and matched to New York State's Congenital Malformations Registry. Reported structural birth defects were compared with numbers expected from state rates (excluding New York City), generating standardized prevalence ratios (SPRs). Exposure assessors classified employees as ever/never potentially exposed at the facility to metals, chlorinated hydrocarbons, and other hydrocarbons during windows critical to organogenesis (female workers) or spermatogenesis (male workers). Among workers, adjusted prevalence ratios were generated to evaluate associations between potential exposures and specific birth defects.ResultsExternal comparisons for structural defects were at expectation for infants of male workers (SPR = 1.01; 95% confidence interval [CI], 0.77–1.29; n = 60) and lower for births to female workers (SPR = 0.84; 95% CI, 0.50–1.33; n = 18). Among full‐term infants of male workers, ventricular septal defects (VSDs) were somewhat elevated compared with the general population (SPR = 1.58; 95% CI, 0.99–2.39; n = 22). Within the cohort, potential paternal metal exposure was associated with increased VSD risk (adjusted prevalence ratio = 2.70; 95% CI, = 1.09–6.67; n = 7).ConclusionWhile overall SPRs were near expectation, paternal exposure to metals (primarily lead) appeared to be associated with increased VSD risk in infants. Take‐home of occupational exposures, nonoccupational exposures, and chance could not be ruled out as causes. Case numbers for many defects were small, limiting assessment of the role of occupational exposures. Birth Defects Research (Part A) 106:696–707, 2016. © 2016 Wiley Periodicals, Inc.

Published: May 2016

In order to evaluate the chemical diversity of Laurencia dendroidea J. Agardh, a widely distributed seaweed in Brazilian coast, a phytochemical study was carried out with algae collected from six different locations along the Southeast Brazilian coast. Purified compounds were identified by MS and NMR techniques. The chemical profiles of lipophilic extracts were obtained by GC/MS for each population. In total, 15 compounds were described. The sesquiterpene composition accounted for 49 – 63% of the GC/MS chromatogram area. The discrimination of three chemotypes was done by the use of HCA on GC/MS chromatograms. They were also analyzed by the PCA and, together with peak area analysis, it was possible to discriminate all populations by the main variation of elatol, obtusol, rogiolol, and triquinane. The results revealed the high diversity of sesquiterpene composition among populations of L. dendroidea. Curiously, the within and among population variation of elatol and obtusol suggested a biochemical interplay on the content of these compounds. More studies are necessary to understand the patterns of chemical diversity and compound variation within and among populations of L. dendroidea.

Published: May 2016

AbstractIntroduction of bioorthogonal functionalities (e.g., trans‐cyclooctene‐TCO) into a protein of interest by site‐specific genetic encoding of non‐canonical amino acids (ncAAs) creates uniquely targetable platforms for fluorescent labeling schemes in combination with tetrazine‐functionalized dyes. However, fluorescent labeling of an intracellular protein is usually compromised by high background, arising from the hydrophobicity of ncAAs; this is typically compensated for by hours‐long washout to remove excess ncAAs from the cellular interior. To overcome these problems, we designed, synthesized, and tested new, hydrophilic TCO‐ncAAs. One derivative, DOTCO‐lysine was genetically incorporated into proteins with good yield. The increased hydrophilicity shortened the excess ncAA washout time from hours to minutes, thus permitting rapid labeling and subsequent fluorescence microscopy.
Solution Structure of Turbo‐Hauser Base TMPMgCl⋅LiCl in [D8]THF
Authors: Neufeld Roman , Stalke Dietmar 
Published: May 2016

AbstractTurbo‐Hauser bases are very useful and highly reactive organometallic reagents in synthesis. Especially TMPMgCl⋅LiCl 1 (TMP=2,2,6,6‐tetramethylpiperidide) is an excellent base for converting a wide range of (hetero)aromatic substrates into highly functionalized compounds with a broad application in organic synthesis. The knowledge of its structure in solution is of essential importance to understand the extraordinary reactivity and selectivity. However, very little is known about the aggregation of this prominent reagent in solution. Herein, we present the THF‐solution structure of 1 by employing our newly elaborated DOSY NMR method based on external calibration curves (ECC) with normalized diffusion coefficients.
Turn‐On Fluorogenic and Chromogenic Detection of Small Aromatic Hydrocarbon Vapors by a Porous Supramolecular Host
Authors: Hatanaka Sou , Ono Toshikazu , Hisaeda Yoshiio 
Published: May 2016

AbstractBenzene, toluene, ethylbenzene, the isomers of xylene, and trimethylbenzene are harmful volatile organic compounds and pose risks to human health and the environment. However, there are currently no effective chemosensors for vapors of these compounds. A porous supramolecular host for turn‐on fluorogenic and chromogenic detection of the vapors of small aromatic hydrocarbons is presented. The host was constructed from a naphthalenediimide derivative that was supramolecularly connected to tris(pentafluorophenyl)borane. The amorphous powder form of the host allowed for effective accommodation of vapors of small aromatic hydrocarbons, resulting in a guest‐dependent fluorescence emission. Increases in the fluorescence yield of 76‐, 46‐, and 37‐fold were observed with toluene, benzene, and m‐xylene, respectively. Negligible responses were obtained with common organic solvents. This simple supramolecular host could be applied as a useful sensor of small aromatic hydrocarbon vapors.
Structural Basis for Bulky‐Adduct DNA‐Lesion Recognition by the Nucleotide Excision Repair Protein Rad14
Authors: Simon Nina , Ebert Charlotte , Schneider Sabine 
Published: May 2016

AbstractHeterocyclic aromatic amines react with purine bases and result in bulky DNA adducts that cause mutations. Such structurally diverse lesions are substrates for the nucleotide excision repair (NER). It is thought that the NER machinery recognises and verifies distorted DNA conformations, also involving the xeroderma pigmentosum group A and C proteins (XPA, XPC) that act as a scaffold between the DNA substrate and several other NER proteins. Here we present the synthesis of DNA molecules containing the polycyclic, aromatic amine C8‐guanine lesions acetylaminophenyl, acetylaminonaphthyl, acetylaminoanthryl, and acetylaminopyrenyl, as well as their crystal structures in complex with the yeast XPA homologue Rad14. This work further substantiates the indirect lesion‐detection mechanism employed by the NER system that recognises destabilised and deformable DNA structures.
