Published: June 2008

Novel ruthenium (II) complexes were prepared containing 2‐phenyl‐1,8‐naphthyridine derivatives. The coordination modes of these ligands were modified by addition of coordinating solvents such as water into the ethanolic reaction media. Under these conditions 1,8‐naphthyridine (napy) moieties act as monodentade ligands forming unusual [Ru(CO)2Cl2(η1‐2‐phenyl‐1,8‐naphthyridine‐kN)(η1‐2‐phenyl‐1,8‐naphthyridine‐kN′)] complexes. The reaction was reproducible when different 2‐phenyl‐1,8‐naphthyridine derivatives were used. On the other hand, when dry ethanol was used as the solvent we obtained complexes with napy moieties acting as a chelating ligand. The structures proposed for these complexes were supported by NMR spectra, and the presence of two ligands in the [Ru(CO)2Cl2(η1‐2‐phenyl‐1,8‐naphthyridine‐kN)(η1‐2‐phenyl‐1,8‐naphthyridine‐kN′)] type complexes was confirmed using elemental analysis. All complexes were tested as catalysts in the hydroformylation of styrene showing moderate activity in N,N′‐dimethylformamide. Copyright © 2008 John Wiley & Sons, Ltd.

Authors: Patel M. N. , Pansuriya P. B. , Chhasatia M. R.
Published: June 2008

The mixed‐ligand complexes of iron(III) with 1‐cyclopropyl‐6‐fluoro‐4‐oxo‐7‐piperazin‐1‐yl‐1,4‐dihydroquinoline‐3‐carboxylic acid and various neutral bidentate Schiff base ligands were prepared. The structure of mixed‐ligand complexes was investigated using spectral, physicochemical and elemental analyses. Biocidal activity was determined using agar plate technique against Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Salmonella typhi, Escherichia coli and Serratia marcescens. The result showed a significant increase in a biocidal activity compared with parent ligands, metal salts and standard drugs (ofloxacin, levofloxacin). DNA binding and cleavage studies were carried out using absorption titration and gel electrophoresis techniques, respectively. The binding constant of Fe(III) complexes was obtained in the range 2.5–4.0 × 104 M−1. The DNA binding and cleavage efficacy were raised in mixed‐ligand complexes as compared with parental ligands and metal salts. Copyright © 2008 John Wiley & Sons, Ltd.

Published: June 2008

A series of ortho‐(aminomethyl)phenylboronic acids was synthesized and their structures were determined by single‐crystal X‐ray diffraction. The structures are stabilized by the inter‐ and intramolecular hydrogen bonds. The sugar‐binding ability of these compounds was evaluated for D‐glucose, D‐fructose and D‐galactose by the competition assay with Alizarin Red S (ARS). The results indicate that the sugar binding ability and selectivity towards sugars depend on the substituents in amino group. Copyright © 2008 John Wiley & Sons, Ltd.
Effect of diorganotin(IV) carboxylate complexes, [N‐(2‐carboxyphenyl) salicylideneiminato]dimethyltin(IV), bis(µ3‐oxo)bis(µ‐O‐aminobenzoato‐O,O′) bis(O‐aminobenzoato)tetrakis[dimethyltin(IV)] and bis(O‐aminobenzoato‐O,O′) di‐n‐butyltin(IV), on the membrane of Candida albicans cells—a mechanistic investigation of the antifungal activity of organotin complexes

Published: June 2008

The in vitro anti‐fungal activity of diorganotin(V) carboxylate complexes, [N‐(2‐carboxyphenyl)salicylideneiminato] dimethyltin(IV) (1), bis(µ3‐oxo)bis(µ‐O‐aminobenzoato‐O,O′)bis(O‐aminobenzoato)tetrakis[dimethyltin(IV)] (2) and bis(O‐ aminobenzoato‐O,O′)di‐n‐butyltin(IV) (3) has been screened against Candida albicans. The complexes, prepared by minor modifications of a literature method, have been fully characterized. The biological activities of complexes 1–3 on cultures of Candida albicans have been studied and the related mechanism has been investigated. No changes in DNA integrity or in the mitochondria function have been observed. However, all the tin compounds were found to reduce the ergosterol biosynthesis. The compounds have inhibitory concentrations (IC50) in the range of 7.5–20.0 µg ml−1, with compound 3 the most active. These results were compared with those provided by the literature, using myconazole, amphotericin B and fluconazole as standards. Scanning electron microscopy and transmission electron microscopy of the cells treated with complexes 1–3, revealed severe damage on the C. albicans cells compromising the cellular integrity, suggesting that the organotin complexes act on the cell membrane, in view of cytoplasm leaking and cellular deformation. The data indicate for 1–3 a mechanism of action similar to that of azole drugs, such as ketoconazole or fluconazole, normally used in Candida infections. Copyright © 2008 John Wiley & Sons, Ltd.
New fire‐protective intumescent coatings for wood
Authors: Hassan M. A. , Kozlowski Ryszard , Obidzinski Bartoz
Published: June 2008

Polyurethane coatings are highly flammable, and because of their widespread applications on different substrates (wood, steel, and building materials), there is a need to increase their fire‐safety properties. Intumescent additives sharply suppress the flammability properties of polyurethane coatings. Two problems accompany intumescent additives: their high loading percentage and incompatibility with polyurethane coatings. In this research, we succeeded in increasing the compatibility by mixing intumescent additives with a butyl acrylate polymer and in lowering the flame‐retardant additive loading (up to 20%) by incorporating newly modified montmorillonite. The flammability properties of the new intumescent coatings were characterized with a cone calorimeter. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Structural, thermal, and tribological properties of intercalated polyoxymethylene/molybdenum disulfide nanocomposites
Authors: Wang J. , Hu K. H. , Xu Y. F. , Hu X. G.
Published: June 2008

Intercalated polyoxymethylene (POM)/molybdenum disulfide (MoS2) nanocomposites were prepared by in situ intercalation/polymerization. The structures of the composites were characterized by means of powder X‐ray diffraction (XRD) and transmission electron microscopy. The XRD pattern showed that the polymer was inserted into the MoS2 galleries. The interlayer spacing of the intercalated phase increased from 6.15 to 11.18 Å. The thermal behavior of the composites was also investigated through thermogravimetric analysis. The results show that the heat resistance of the intercalated composites decreased slightly. The tribological behavior of POM/MoS2 was investigated on an MQ‐800 end‐face tirbometer under dry friction. The worn surfaces were observed by scanning electron microscopy. The results show that POM/MoS2 presented better friction reduction and wear resistance, especially under high load. The friction mechanism of the nanocomposites is also discussed in association with X‐ray photoelectron spectroscopy. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Observations of physical aging in a polycarbonate and acrylonitrile–butadiene–styrene blend
Authors: Tang Jacky K. Y. , Lee‐Sullivan Pearl
Published: June 2008

The effects of physical aging of a 75 : 25 PC/ABS blend have been studied using differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR). From DSC, two distinct peak endotherms at about 90°C and 110°C, which are associated with the glass transition of ABS (Tg,ABS) and PC (Tg,PC) components, respectively, were observed. When progressive aging was monitored at 80°C for over 1000 h, the changes in enthalpic relaxation, glass and fictive temperatures for the blend followed similar trends to those already seen in the literature for PC aged between 125 and 130°C. The rate of enthalpy relaxation was also comparable. The plot of peak endotherm against logarithmic aging time for the PC blend constituent, however, behaved quite differently from the linear relationship known for highly aged PC. The ABS peak component also appeared to be insensitive to aging. Both observations were confirmed to be statistically significant using analysis of variance methods. Using temperature modulated‐DSC, there is evidence that aging increases the blend miscibility as the Tg,PC shifts toward the stationary Tg,ABS during aging. Parallel FTIR investigations found oxidation of butadiene during aging to be even at this relatively low temperature, forming hydroxyl and carbonyl degradation products. The presence of ABS in the blend also appeared to have prevented the shifting from the trans‐cis to trans‐trans arrangement of the carbonate linkage, which is a well‐known phenomenon during elevated temperature aging of PC alone. Moreover, the carbonate linkage appears to have been at the lower energy, trans‐trans, arrangement prior to the aging process. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Release behavior of freeze‐dried alginate beads containing poly(N‐isopropylacrylamide) copolymers
Authors: Choi Jae‐Hyung , Lee Hyeon Yong , Kim Jin‐Chul
Published: June 2008

Beads composed of alginate, poly(N‐isopropylacrylamide) (PNIPAM), the copolymers of N‐isopropylacrylamide and methacrylic acid (P(NIPAM‐co‐MAA)), and the copolymers of N‐isopropylacrylamide, methacrylic acid, and octadecyl acrylate (P(NIPAM‐co‐MAA‐co‐ODA)), were prepared by dropping the polymer solutions into CaCl2 solution. The beads were freeze‐dried and the release of blue dextran entrapped in the beads was observed in distilled water with time and pH. The degree of release was in the order of alginate bead < alginate/PNIPAM bead ≈ alginate/P(NIPAM‐co‐MAA) bead < alginate/P(NIPAM‐co‐MAA‐co‐ODA) bead. On the other hand, swelling ratios reached steady state within 20 min, and the values were 200–800 depending on the bead composition. The degree of swelling showed the same order as that of release. Among the beads, only alginate/P(NIPAM‐co‐MAA‐co‐ODA) bead exhibited pH‐dependent release. At acidic condition, inter‐ and intraelectrostatic repulsion is weak and P(NIPAM‐co‐MAA‐co‐ODA) could readily be assembled into an aggregate due to the prevailing hydrophobic interaction of ODA. Thus, it could block the pore of bead matrix, leading to a suppressed release. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Oxidative polymerization of pyrrole photocatalyzed by TiO2 nanoparticles and interactions in the composites
Authors: Weng Zhen , Ni Xiuyuan
Published: June 2008

Oxidative polymerization of pyrrole is initiated by photoexcited TiO2 nanoparticles. Pyrrole oligomers and polypyrrole (PPy) are continuously produced with reaction time. The conversion of pyrrole monomer changes as a function of the concentration of TiO2 nanoparticles. It is found that PPy in the composite has the conjugated structure and is partially oxidized with a formation of positively charged N+. Results from X‐ray photoelectron spectroscopy and Raman analysis consistently indicate that a strong interaction is established between the TiO2 and PPy. According to the results of UV–vis spectroscopy, a mechanism of photocatalytic oxidation is proposed for this polymerization. The interaction between TiO2 and PPy is found to arise from the photocatalytic reaction and discussed in terms of photoinduced Ti3+. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Diffusion‐Influenced Excited‐State Reversible Geminate ABCD Reaction in the Presence of an External Field
Authors: Park Soohyung , Shin Kook Joe
Published: June 2008

We obtained the exact Green functions, in the Laplace domain, for a diffusion‐influenced excited‐state reversible geminate ABCD reaction with two different lifetimes and quenching processes under a constant external field in one dimension. Analytic expressions for the survival probabilities of the initial and final states are obtained in the time domain at short and long times, respectively. The short‐time approximations obtained in this work are valid for ${t \char60 \left| K \right|^{ - 1} }$, where K depends on several parameters of the system. The analysis of the long‐time asymptotic behaviors reveals rather complex kinetic transitions dependent upon the field and lifetimes. We also find a destructive interplay leading to the reduction in the number of kinetic transitions similar to that found for the excited‐state geminate ABC reaction with an external field in one dimension.
Aryl Triolborates: Novel Reagent for Copper‐Catalyzed N Arylation of Amines, Anilines, and Imidazoles
Authors: Yu Xiao‐Qiang , Yamamoto Yasunori , Miyaura Norio
Published: June 2008

The N arylation of primary and secondary aliphatic amines, anilines, and imidazoles with novel potassium aryl triolborates was carried out in the presence of a reoxidant and a catalytic amount of Cu(OAc)2 (10 mol %). Aryl triolborates were found to be better reagents than aryl boronic acids or potassium aryl trifluoroborates as the former achieved high yields under mild conditions. Coupling of primary and secondary aliphatic amines to give N‐aryl amines in excellent yields was performed under oxygen atmosphere. The reactions of anilines and imidazoles to provide N‐aryl anilines and N‐aryl imidazoles in good yields proceeded smoothly when trimethylamine N‐oxide was used as an oxidant.
A hybrid framework for resource allocation among multiple agents moving on discrete environments
Authors: Piovesan Jorge L. , Abdallah Chaouki T. , Tanner Herbert G.
Published: June 2008

We consider the problem of controlling a multi‐agent system whose agents move across discrete locations. The agents attempt to extract resources from the environment while the environment, which may vary as the system evolves, distributes its resources according to the agents requests. The environment is modeled as a network of discrete nodes. Our ultimate goal is to design the dynamical policies that determine the behavior of agents and nodes, such that the usage of resources in the network is optimized. We propose a hybrid model to describe both agents and nodes. Several components of this model are design variables that may be obtained analytically. We then formulate an optimization problem that may be decomposed into two hierarchical optimization problems: an integer optimization problem that considers the distribution of agents among the nodes of the network; and a convex optimization problem within each node that corresponds to the distribution of resources of each node among its resident agents. We show that the optimization problem within each node is a special case of the formulation that models congestion control algorithms in the internet. We then use available results to solve a portion of the proposed hybrid description for agents and nodes. Moreover, we show that the resulting continuous dynamics are globally asymptotically stable, with their equilibrium point coinciding with the solution of the optimization problem. As a consequence, the proposed continuous dynamics yield an interconnected system that is stable on each possible configuration of agents and nodes.

Antioxidants for improving storage stability of biodiesel
Authors: Dunn Robert O.
Published: June 2008

Biodiesel is an alternative diesel fuel made from vegetable oil or animal fat that may be burned in a compression‒ignition (diesel) engine. The chemical nature of biodiesel makes it more susceptible to oxidation or autoxidation during long‒term storage than conventional petroleum‒based diesel (petrodiesel). Oxidative degradation during storage can compromise fuel quality with respect to effects on kinematic viscosity, acid value (number), cetane number, total ester content, and formation of hydroperoxides, soluble polymers, and other secondary products. One promising method of increasing the resistance to oxidation of biodiesel is to add oxidation inhibitors (antioxidants). This review summarizes relevant research progress in the development of effective antioxidants for treating biodiesel. Performance of antioxidants evaluated for treating biodiesel derived from soybean oil, rapeseed (low‒erucic) oil, used cooking oil, tallow (beef), and palm oil feedstocks is discussed.

Unique spatial and cellular expression patterns of Hoxa5, Hoxb4, and Hoxb6 proteins in normal developing murine lung are modified in pulmonary hypoplasia
Authors: Volpe MaryAnn Vitoria , Wang Karen Ting Wai , Nielsen Heber Carl , Chinoy Mala Romeshchandra
Published: June 2008

BACKGROUND:

Hox transcription factors modulate signaling pathways controlling organ morphogenesis and maintain cell fate and differentiation in adults. Retinoid signaling, key in regulating Hox expression, is altered in pulmonary hypoplasia. Information on pattern‐specific expression of Hox proteins in normal lung development and in pulmonary hypoplasia is minimal. Our objective was to determine how pulmonary hypoplasia alters temporal, spatial, and cellular expression of Hoxa5, Hoxb4, and Hoxb6 proteins compared to normal lung development.

METHODS:

Temporal, spatial, and cellular Hoxa5, Hoxb4, and Hoxb6 expression was studied in normal (untreated) and nitrofen‐induced hypoplastic (NT‐PH) lungs from gestational day 13.5, 16, and 19 fetuses and neonates using Western blot and immunohistochemistry.

RESULTS:

Modification of protein levels and spatial and cellular Hox expression patterns in NT‐PH lungs was consistent with delayed lung development. Distinct protein isoforms were detected for each Hox protein. Expression levels of the Hoxa5 and Hoxb6 protein isoforms changed with development and were altered further in NT‐PH lungs. Compared to normal lungs, GD19 and neonatal NT‐PH lungs had decreased Hoxb6 and increased Hoxa5 and Hoxb4. Hoxa5 cellular localization changed from mesenchyme to epithelia earlier in normal lungs. Hoxb4 was expressed in mesenchyme and epithelial cells throughout development. Hoxb6 remained mainly in mesenchymal cells around distal airways.

CONCLUSIONS:

Unique spatial and cellular expression of Hoxa5, Hoxb4, and Hoxb6 participates in branching morphogenesis and terminal sac formation. Altered Hox protein temporal and cellular balance of expression either contributes to pulmonary hypoplasia or functions as a compensatory mechanism attempting to correct abnormal lung development and maturation in this condition.

Published: June 2008

This article presents an investigation of the effect of salt and phage concentrations on the binding affinity of magnetoelastic (ME) biosensors. The sensors were fabricated by immobilizing filamentous phage on the ME platform surface for the detection of Bacillus anthracis spores. In response to the binding of spores to the phage on the ME biosensor, a corresponding decrease occurs in resonance frequency. Transmission electron microscopy (TEM) was used to verify the structure of phage under different combinations of salt/phage concentration. The chemistry of the phage solution alters phage bundling characteristics and, hence, influences both the sensitivity and detection limit of the ME biosensors. The frequency responses of the sensors were measured to determine the effects of salt concentration on the sensors' performance. Scanning electron microscopy (SEM) was used to confirm and quantify the binding of spores to the sensor surface. This showed that 420 mM salt at a phage concentration of 1 × 1011 vir/mL results in an optimal distribution of immobilized phages on the sensor surface, consequently promoting better binding of spores to the biosensor's surface. Additionally, the sensors immobilized with phage under this condition were exposed to B. anthracis spores in different concentrations ranging from 5 × 101 to 5 × 108 cfu/mL in a flowing system. The results showed that the sensitivity of this ME biosensor was 202 Hz/decade. Biotechnol. Bioeng. © 2008 Wiley Periodicals, Inc.
Laparoscopic resection for colorectal cancer
Authors: Buchanan G N , Malik A , Parvaiz A , Sheffield J P , Kennedy R H
Published: June 2008

Background

This study examined one surgeon's practice to determine the place of laparoscopic colorectal cancer surgery.

Methods

Some 365 patients undergoing elective colorectal cancer resection (219 colonic, 146 rectal) were studied prospectively. Early (1994–1997; 104 patients), middle (1998–2001; 112) and late (2002–2005; 149) cohorts were analysed with respect to suitability for laparoscopic surgery, conversion and outcome.

Results

Forty-six of 135 patients undergoing open resection were suitable for laparoscopic surgery but randomized to open surgery. The proportion of attempted laparoscopic resections (35·6, 65·2 and 80·6 per cent in early, middle and late cohorts) and patients thought suitable for laparoscopic resection (37·5, 87·5 and 94·0 per cent respectively; P = 0·001) increased over time. Independent predictors of conversion were rectal cancer surgery (odds ratio (OR) 3·12 versus colonic surgery) and body mass index 28 kg/m2 or more (OR 3·87). Conversion was necessary in all five patients with a threatened margin predicted by preoperative magnetic resonance imaging. After exclusion of these patients the conversion rate in the late cohort was 8·7 per cent. During the same period, inclusion of 20 patients who were suitable for laparoscopic surgery but underwent open resection meant that 135 (90·6 per cent) of 149 patients were actually suitable for laparoscopic resection.

Conclusion

With experience, laparoscopic surgery is feasible in around 90 per cent of elective colorectal cancer resections.
Exploring the Conserved Water Site and Hydration of a Coiled‐Coil Trimerisation Motif: A MD Simulation Study
Authors: Dolenc Jožica , Baron Riccardo , Missimer John H. , Steinmetz Michel O. , van Gunsteren Wilfred F.
Published: June 2008

The solvent structure and dynamics around ccβ‐p, a 17‐residue peptide that forms a parallel three‐stranded α‐helical coiled coil in solution, was analysed through 10 ns explicit solvent molecular dynamics (MD) simulations at 278 and 330 K. Comparison with two corresponding simulations of the monomeric form of ccβ‐p was used to investigate the changes of hydration upon coiled‐coil formation. Pronounced peaks in the solvent density distribution between residues Arg8 and Glu13 of neighbouring helices show the presence of water bridges between the helices of the ccβ‐p trimer; this is in agreement with the water sites observed in X‐ray crystallography experiments. Interestingly, this water site is structurally conserved in many three‐stranded coiled coils and, together with the Arg and Glu residues, forms part of a motif that determines three‐stranded coiled‐coil formation. Our findings show that little direct correlation exists between the solvent density distribution and the temporal ordering of water around the trimeric coiled coil. The MD‐calculated effective residence times of up to 40 ps show rapid exchange of surface water molecules with the bulk phase, and indicate that the solvent distribution around biomolecules requires interpretation in terms of continuous density distributions rather than in terms of discrete molecules of water. Together, our study contributes to understanding the principles of three‐stranded coiled‐coil formation.

Perturbing genes: The incorporation of >100 HSV‐tk plasmid molecules into a single, ordered, concatemer when injected into somatic cells was the first demonstration of homologous recombination between cointroduced DNA molecules in cultured mammalian cells. From this came first the idea that manipulating this efficient machinery would allow any endogenous cellular gene in cultured cells to be mutated in any chosen way, and, eventually, the award of the 2007 Nobel Prize for Physiology or Medicine.
