Optimal performances of ultrasound treated kenaf fiber reinforced recycled polypropylene composites as demonstrated by response surface method
Authors: Islam M. R. , Beg M. D. H. , Gupta A. , Mina M. F. 
Published: August 2012

AbstractKenaf fiber (KF) reinforced recycled polypropylene (RPP) composites were produced by melt cast method. To improve interfacial adhesion between fiber and RPP matrix, fiber surface modification was carried out by means of ultrasound treatment. Maleic anhydride grafted polypropylene (MAPP) was used as a coupling agent. Composites were examined by mechanical test, melt flow indexing test, scanning electron microscopy, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). Water uptake analysis and accelerated weathering test were carried out to find the suitability of the composites in outdoor application. Among the raw fiber contents ranging 10−50 wt % in the composites, the maximum tensile strength (TS) was observed at 40 wt % KF loading without using MAPP. Treated KF‐based composite with MAPP promotes this maximum TS value, which is 57% higher than that of raw KF‐based composite. TGA and DSC analyses exhibit an enhancement of thermal stability in treated KF‐reinforced RPP composites with MAPP. Incorporation of MAPP in the composites shows higher activation energy, suggesting improved interfacial bonding between fibers and matrix. Response surface method was employed to demonstrate the optimal treatment parameters for TS, showing excellent agreement with the observed values. © 2012 Wiley Periodicals, Inc. J. Appl. Polym.

Poly(ether imide)‐modified benzoxazine blends: Influences of phase separation and hydrogen bonding interactions on the curing reaction
Authors: Zhao Pei , Liang Xiaomin , Chen Jie , Ran Qichao , Gu Yi 
Published: August 2012

AbstractPolymer blends of polybenzoxazine (PBZ)/poly(ether imide) (PEI) were prepared by the in situ curing reaction of benzoxazine (BZ) resin in the presence of PEI. Phase separation induced by the polymerization of BZ resin was observed. The rheological behaviors, morphologies, and their evolution process of BZ/PEI blends were investigated by rheometer and scanning electron microscope. Phase separation that took place at the early stage of the curing reaction effectively reduced the dilution effect of PEI. Fourier transform infrared (FTIR) results suggested that hydrogen bonds between PBZ and PEI existed during the whole curing process, although weakened with phase separation. The decrease of isoconversion activation energy indicated that the polymerization of BZ resin was facilitated in the presence of such kind of hydrogen‐bonding interactions. By changing the weight fraction of PEI, extensive phase separation was obtained in PBZ blends with 5 and 20 wt % of PEI, in which systems, the crosslinking density and glass transition temperature (Tg) of PBZ‐rich phase were greatly improved compared to this single PBZ system. © 2012 Wiley Periodicals, Inc.

Authors: Yang Wei , Zhang Jiejing , Wang Yuxin 
Published: August 2012

AbstractNovel charged membranes were prepared with sulfonated poly(ether ether ketone) (SPEEK). Methylsulfonic acid was used as solvent to accommodate the very low degree of sulfonation of the SPEEK. Membranes were prepared by immersion phase inversion method, using coagulation baths of different composition and temperature. Low molecular weight and negatively charged dye molecules were used as model solutes to test the nanofiltration (NF) performance of the membranes. Higher than 93% rejection of the two dye molecules, Rose Bengal and Reactive Brilliant Red, was observed at normal operating temperature. A permeate flux as high as 497 L m−2 h−1 and higher than 90% of solute rejection at 80°C was achieved in the NF of Reactive Brilliant Red aqueous solution, in contrast to a flux of 226 L m−2 h−1 and about 78% of solute rejection at the same temperature in the case of Rose Bengal solute. © 2012 Wiley Periodicals, Inc.

Published: August 2012

ABSTRACTCilostazol (CLZ) and atorvastatin (ATV) are often co‐prescribed to treat conditions such as peripheral arterial disease. In the present study, the drug–drug interaction potential of multi‐dose ATV co‐administration with CLZ on both pharmacokinetics and the anti‐thrombotic property of CLZ is demonstrated. The pharmacokinetic parameters of CLZ (6 mg/kg, twice daily) were determined in male Wistar rats after 7 days co‐administration with ATV (5 mg/kg, once daily) in order to assess the interaction potential between CLZ and ATV on chronic treatment. In vitro metabolic inhibition and everted gut sac studies were conducted to elucidate the mechanism of this interaction. Pharmacodynamic drug–drug interaction was evaluated on anti‐thrombotic models including time to occlusion, platelet aggregation and rat tail bleeding time. A validated LC‐MS/MS method was employed simultaneously to quantify both ATV and CLZ in rat plasma matrix. A statistically significant increase in systemic exposure (Cssmax by ~1.75 fold; AUC by ~3.0 fold) to CLZ was observed in ATV pre‐treated rats. In vitro metabolism studies using liver microsomes (RLM and HLM) demonstrated statistically significant inhibition of CLZ metabolism when co‐incubated with ATV. No change in apparent permeability of CLZ was observed in the presence of ATV. Atorvastatin showed a significant delay in artery occlusion time without altering CLZ's bleeding time and platelet aggregation profile. Collectively the results of these studies provide metabolic insight into the nature of drug–drug interaction between the selected drugs. Co‐administration with ATV influences the pharmacokinetics and anti‐thrombotic property of CLZ. A thorough clinical investigation is required before extrapolation of data to humans.

Authors: Kobayashi Kaoru , Kajiwara Eri , Ishikawa Masayuki , Oka Hidenobu , Chiba Kan 
Published: August 2012

ABSTRACTBenzbromarone (BBR) is metabolized to 1′‐hydroxy BBR and 6‐hydroxy BBR in the liver. 6‐Hydroxy BBR is further metabolized to 5,6‐dihydroxy BBR. The aim of this study was to identify the CYP isozymes involved in the metabolism of BBR to 1′‐hydroxy BBR and 6‐hydroxy BBR and in the metabolism of 6‐hydroxy BBR to 5,6‐dihydroxy BBR in human liver microsomes. Among 11 recombinant P450 isozymes examined, CYP3A4 showed the highest formation rate of 1′‐hydroxy BBR. The formation rate of 1′‐hydroxy BBR significantly correlated with testosterone 6β‐hydroxylation activity in a panel of 12 human liver microsomes. The formation of 1′‐hydroxy BBR was completely inhibited by ketoconazole in pooled human liver microsomes. On the other hand, the highest formation rate of 6‐hydroxy BBR was found in recombinant CYP2C9. The highest correlation was observed between the formation rate of 6‐hydroxy BBR and diclofenac 4′‐hydroxylation activity in 12 human liver microsomes. The formation of 6‐hydroxy BBR was inhibited by tienilic acid in pooled human liver microsomes. The formation of 5,6‐dihydroxy BBR from 6‐hydroxy BBR was catalysed by recombinant CYP2C9 and CYP1A2. The formation rate of 5,6‐dihydroxy BBR was significantly correlated with diclofenac 4′‐hydroxylation activity and phenacetin O‐deethylation activity in 12 human liver microsomes. The formation of 5,6‐dihydroxy BBR was inhibited with either tienilic acid or α‐naphthoflavone in human liver microsomes. These results suggest that (i) the formation of 1′‐hydroxy BBR and 6‐hydroxy BBR is mainly catalysed by CYP3A4 and CYP2C9, respectively, and (ii) the formation of 5,6‐dihydroxy BBR is catalysed by CYP2C9 and CYP1A2 in human liver microsomes.

Comparative pharmacokinetic study of paclitaxel and docetaxel in streptozotocin‐induced diabetic rats
Authors: Lee Joo Hyun , Lee Areum , Oh Ju‐Hee , Lee Young‐Joo 
Published: August 2012

ABSTRACTThe pharmacokinetics of paclitaxel and docetaxel were compared in diabetic rats induced by streptozotocin (DMIS rats) and the impact of altered expression of cytochrome P450 3A (Cyp3A) and P‐glycoprotein (P‐gp) in the diabetic state. The pharmacokinetics of paclitaxel and docetaxel were determined after intravenous (5 mg/kg) and oral (30 and 40 mg/kg, respectively) administration to both groups and the mRNA expression levels of Cyp3A isozymes and Mdr1a and Mdr1b in the liver and small intestine were determined in control and DMIS rats. After intravenous administration, the AUC and clearance of paclitaxel and docetaxel were not significantly different in DMIS vs control rats. After oral administration, the AUC and Cmax of paclitaxel in DMIS rats were significantly greater than those in the control rats, whereas those of docetaxel was not changed significantly. The mRNA expression levels of hepatic Cyp3A1, Cyp3A9 and Mdr1b were significantly increased in DMIS compared with the control rats. In the intestine, Cyp3A62 expression decreased in the DMIS rats compared with the controls. Thus the pharmacokinetic changes of taxanes observed in the DMIS rats were attributed to changes in P‐gp and Cyp3A, predominant factors that control the absorption of paclitaxel and docetaxel, respectively. It seemed that there were different susceptibilities to intestinal P‐gp and Cyp3A between the two taxanes. Copyright © 2012 John Wiley & Sons, Ltd.
Photosynthetic efficiency and rate of CO2 assimilation by Arthrospira (Spirulina) platensis continuously cultivated in a tubular photobioreactor

Published: August 2012

AbstractSimilar to other photosynthetic microorganisms, the cyanobacterium Arthrospira platensis can be used to produce pigments, single cell proteins, fatty acids (which can be used for bioenergy), food and feed supplements, and biofixation of CO2. Cultivation in a specifically designed tubular photobioreactor is suitable for photosynthetic biomass production, because the cultivation area can be reduced by distributing the microbial cells vertically, thus avoiding loss of ammonia and CO2. The aim of this study was to investigate the influence of light intensity and dilution rate on the photosynthetic efficiency and CO2 assimilation efficiency of A. platensis cultured in a tubular photobioreactor in a continuous process. Urea was used as a nitrogen source and CO2 as carbon source and for pH control. Steady‐state conditions were achieved in most of the runs, indicating that continuous cultivation of this cyanobacterium in a tubular photobioreactor could be an interesting alternative for the large‐scale fixation of CO2 to mitigate the greenhouse effect while producing high protein content biomass.
Efficient reversal of phiC31 integrase recombination in mammalian cells
Authors: Farruggio Alfonso P. , Chavez Christopher L. , Mikell Carlos L. , Calos Michele P. 
Published: August 2012

AbstractOver the past decade, the integrase enzyme from phage phiC31 has proven to be a useful genome engineering tool in a wide variety of species, including mammalian cells. The enzyme efficiently mediates recombination between two distinct sequences, attP and attB, producing recombinant product sites, attL and attR. The reaction proceeds exclusively in a unidirectional manner, because integrase is unable to synapse attL and attR. To date, use of phiC31 integrase has been limited to attP × attB recombination. The factor needed for the reverse reaction – the excisionase or recombination directionality factor (RDF) – was identified recently and shown to function in vitro and in bacterial cells. To determine whether the phiC31 RDF could also function in mammalian cells, we cloned and tested several vectors that permit assessment of phiC31 RDF activity in mammalian environments. In the human and mouse cell lines tested (HeLa, HEK293, and NIH3T3), we observed robust RDF activity, using plasmid and/or genomic assays. This work is the first to demonstrate attL–attR serine integrase activity in mammalian cells and validates phiC31 RDF as a new tool that will enable future studies to take advantage of phiC31 integrase recombination in the forward or reverse direction.
Chemical Biology for Understanding Matrix Metalloproteinase Function
Authors: Knapinska Anna , Fields Gregg B. 
Published: August 2012

AbstractThe matrix metalloproteinase (MMP) family has long been associated with normal physiological processes such as embryonic implantation, tissue remodeling, organ development, and wound healing, as well as multiple aspects of cancer initiation and progression, osteoarthritis, inflammatory and vascular diseases, and neurodegenerative diseases. The development of chemically designed MMP probes has advanced our understanding of the roles of MMPs in disease in addition to shedding considerable light on the mechanisms of MMP action. The first generation of protease‐activated agents has demonstrated proof of principle as well as providing impetus for in vivo applications. One common problem has been a lack of agent stability at nontargeted tissues and organs due to activation by multiple proteases. The present review considers how chemical biology has impacted the progress made in understanding the roles of MMPs in disease and the basic mechanisms of MMP action.
Direct Detection of Key Intermediates in Rhodium(I)‐Catalyzed [2+2+2] Cycloadditions of Alkynes by ESI‐MS
Authors: Parera Magda , Dachs Anna , Solà Miquel , Pla‐Quintana Anna , Roglans Anna 
Published: August 2012

AbstractThe mechanism of the Rh‐catalysed [2+2+2] cycloaddition reaction of diynes with monoynes has been examined using ESI‐MS and ESI‐CID‐MS analysis. The catalytic system used consisted of the combination of a cationic rhodium(I) complex with bisphosphine ligands, which generates highly active complexes that can be detected by ESI(+) experiments. ESI‐MS on‐line monitoring has allowed the detection for the first time of all of the intermediates in the catalytic cycle, supporting the mechanistic proposal based mainly on theoretical calculations. For all ESI‐MS experiments, the structural assignments of ions are supported by tandem mass spectrometry analyses. Computer model studies based on density functional theory (DFT) support the structural proposal made for the monoyne insertion intermediate. The collective studies provide new insight into the reactivity of cationic rhodacyclopentadienes, which should facilitate the design of related rhodium‐catalysed CC couplings.
Lanosterol Biosynthesis: The Critical Role of the Methyl‐29 Group of 2,3‐Oxidosqualene for the Correct Folding of this Substrate and for the Construction of the Five‐Membered D Ring
Authors: Hoshino Tsutomu , Chiba Akifumi , Abe Naomi 
Published: August 2012

AbstractLanosterol synthase catalyzes the polycyclization reaction of (3S)‐2,3‐oxidosqualene (1) into tetracyclic lanosterol 2 by folding 1 in a chair‐boat‐chair‐chair conformation. 27‐Nor‐ and 29‐noroxidosqaulenes (7 and 8, respectively) were incubated with this enzyme to investigate the role of the methyl groups on 1 for the polycyclization cascade. Compound 7 afforded two enzymatic products, namely, 30‐norlanosterol (12) and 26‐normalabaricatriene (13; 12/13 9:1), which were produced through the normal chair‐boat‐chair‐chair conformation and an atypical chair‐chair‐boat conformation, respectively. Compound 8 gave two products 14 and 15 (14/15 4:5), which were generated by the normal and the unusual polycyclization pathways through a chair‐chair‐boat‐chair conformation, respectively. It is remarkable that the twist‐boat structure for the B‐ring formation was changed to an energetically favored chair structure for the generation of 15. Surprisingly, 14 and 15 consisted of a novel 6,6,6,6‐fused tetracyclic ring system, thus differing from the 6,6,6,5‐fused lanosterol skeleton. Together with previous results, we conclude that the methyl‐29 group is critical to the correct folding of 1, with lesser contributions from the other branched methyl groups, such as methyl‐26, ‐27, and ‐28. Furthermore, we demonstrate that the methyl‐29 group has a crucial role in the formation of the five‐membered D ring of the lanosterol scaffold.
