Preparation of porous chitosan/agarose microsphere and its R‐phycoerythrin release properties
Authors: Xue Zhi‐Xin , Yang Gui‐Peng , Wang Guang‐Ce , Niu Jian‐Feng , Cao Xiao‐Yan
Published: November 2006

The chitosan microspheres (CS‐CL) were prepared by suspension crosslinking method and used as carriers of R‐phycoerythrin (R‐PE). In this study, R‐PE was loaded in the microspheres and released in vitro. The effects of pH value, temperature, ionic strength, and R‐PE concentration on loading efficiency and release behavior were discussed. A novel microsphere that contained agarose (CS‐AR MP) was prepared and the basic loading and releasing behavior for R‐PE of this kind of new microspheres were also investigated. The results showed that all these chitosan microspheres have the ability to control‐release R‐PE. The addition of agarose may somewhat accelerate the release rate of R‐PE from microspheres and reduce the capacity of adsorption for R‐PE. © 2006 Wiley Periodicals, Inc.

Influence of the cross‐sectional shape on the structure and properties of polyester fibers
Authors: Karaca Esra , Ozcelik Feryal
Published: November 2006

The effects of the fiber cross‐sectional shape on the structure and properties of polyester fibers were investigated. Fully drawn yarn (FDY) polyester fibers (167 dtex and 48 filaments) were produced under the same spinning conditions used in a spinning plant. The only difference between the fibers was their cross‐sectional shapes. Four different cross‐sectional shapes were chosen for the experimental work: round, hollow‐round, trilobal, and hollow‐trilobal. The crystallinity and values of the maximum stress, maximum strain, modulus, yield stress, shrinkage in boiling water, and unevenness of the fibers were determined. The difference in the cross‐sectional shapes influenced the modulus, maximum strain, yield stress, and shrinkage in boiling water. No effects on the crystallinity and maximum stress were observed. The results suggested that the hollow fibers had higher amorphous orientation than the full fibers. The hollow‐round fiber had the highest unevenness value. © 2006 Wiley Periodicals, Inc.

Physical and electrochemical properties of low molecular weight poly(ethylene glycol)‐bridged polysilsesquioxane organic–inorganic composite electrolytes via sol–gel process
Authors: Yuan C. Y. , Chen S. Y. , Tang J. C. , Yang H. C. , Chen‐Yang Y. W.
Published: November 2006

A new class of ionic conducting organic/inorganic hybrid composite electrolyte with high conductivity, better electrochemical stability and mechanical behavior was prepared through the sol–gel processing between ethylene‐bridged polysilsesquioxane and poly(ethylene glycol) (PEG). The composite electrolyte with 0.05 LiClO4 per PEG repeat unit has the best conductivity up to 10−4 S/cm at room temperature with the transference number up to 0.48 and an electrochemical stability window as high as 5.5 V versus Li/Li+. Moreover, the effect of the PEG chain length on the properties of the composite electrolyte has also been studied. The interactions between ions and polymer have also been investigated for the composite electrolyte in the presence of LiClO4 by means of FTIR, DSC, and TGA. The results indicated the interaction of Li+ ions with the ether oxygen of the PEG, and the formation of transient crosslinking with LiClO4, resulting in an increase of the Tg of the composite electrolyte. The VTF‐type behavior of the ionic conductivity implied that the diffusion of the charge carriers was assisted by the segmental motions of the polymer chains. © 2006 Wiley Periodicals, Inc.

Thermal and mechanical properties of poly(ε‐caprolactone) crosslinked with γ radiation in the presence of triallyl isocyanurate
Authors: Han Changyu , Ran Xianghai , Zhang Kunyu , Zhuang Yugang , Dong Lisong
Published: November 2006

Poly(ϵ‐caprolactone) was crosslinked by γ radiation in the presence of triallyl isocyanurate. The influence of γ‐radiation crosslinking on the thermal and mechanical properties of poly(ϵ‐caprolactone)/triallyl isocyanurate was investigated. Differential scanning calorimetry analyses showed differences between the first and second scans. Dynamic mechanical analysis showed an increase in the glass‐transition temperature as a result of the radiation crosslinking of poly(ϵ‐caprolactone). Thermogravimetric analysis showed that γ‐radiation crosslinking slightly improved the thermal stability of poly(ϵ‐caprolactone). The γ radiation also strongly influenced the mechanical properties. At room temperature, crosslinking by radiation did not have a significant influence on the Young's modulus and yield stress of poly(ϵ‐caprolactone). However, the tensile strength at break and the elongation at break generally decreased with an increase in the crosslinking level. When the temperature was increased above the melting point, the tensile strength at break, elongation at break, and Young's modulus of poly(ϵ‐caprolactone) were also reduced with an increase in the crosslinking level. The yield stress disappeared as a result of the disappearance of the crystallites. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 103: 2676–2681, 2007
Dielectric behavior of natural rubber composites in microwave fields
Authors: John Honey , Joseph Rani , Mathew K. T.
Published: November 2006

In this article, we report the preparation of conducting natural rubber (NR) with polyaniline (Pani). NR was made into a conductive material by the compounding of NR with Pani in powder form. NR latex was made into a conductive material by the in situ polymerization of aniline in the presence of NR latex. Different compositions of Pani–NR semi‐interpenetrating networks were prepared, and the dielectric properties of all of the samples were determined in microwave frequencies. The cavity perturbation technique was used for this study. A HP8510 vector network analyzer with a rectangular cavity resonator was used for this study. S bands 2–4 GHz in frequency were used. Thermal studies were also carried out with thermogravimetric analysis and differential scanning calorimetry. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 103: 2682–2686, 2007
Fabrication, structures, and properties of acrylonitrile/methyl acrylate copolymers and copolymers containing microencapsulated phase change materials
Authors: Han Na , Zhang Xing‐Xiang , Wang Xue‐Chen
Published: November 2006

The polyacrylonitrile‐methyl acrylate (AN/MA mole ratio 100/0–70/30) copolymers and copolymers (AN/MA mole ratio 85/15) containing up to 40 wt % of microencapsulated n‐octadecane (MicroPCMs) are synthesized in water. The MicroPCMs were incorporated at the step of polymerization. The effect of the MA mole ratio and MicroPCMs content on structures and properties of the copolymers were studied by using Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (1H NMR), scanning electronic microscope (SEM), differential scanning calorimetry (DSC), thermogravimetry analysis (TG), gel permeation chromatography (GPC), and X‐ray diffraction (XRD). The feeding ratio agreed well with the composition of the AN/MA copolymers. The copolymers are synthesized in the presence of MicroPCMs. The melting point moves to lower temperature (206°C), while the decomposition temperature moves to higher temperature (309°C) with increasing of the MA mole ratio and microcapsules content. The number–average molecular weight of the copolymer is ∼30,000. The crystallinity of the copolymer decreases with increasing of the MA mole ratio and microcapsules content. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 103: 2776–2781, 2007
Ion‐exchange membrane based on poly(styrene sulfonic acid‐co‐n‐(2‐hydroxyethyl) acrylamide)
Authors: Tanigami Tetsuya , Iwata Hiroshi , Mori Takamasa
Published: November 2006

A new ion‐exchange membrane was prepared by blending a copolymer of poly(styrene sulfonic acid‐co‐N‐(2‐hydroxyethyl) acrylamide) with poly(vinylidene fluoride). The dissolution of the copolymer into water was prevented by the crosslinked network formed by condensation reaction between N‐(2‐hydoroxyethyl) acrylamide (HEAA) units. The reaction was caused after film‐forming the blend. Swellability in water, ion‐exchange capacity, ion conductivity, and mechanical properties of the membrane were investigated and compared with those of a well‐known ion‐exchange membrane, Nafion 117. © 2006 Wiley Periodicals, Inc.

Presence of significant synovitis in rheumatoid arthritis patients with disease‐modifying antirheumatic drug–induced clinical remission: Evidence from an imaging study may explain structural progression
Authors: Brown A. K. , Quinn M. A. , Karim Z. , Conaghan P. G. , Peterfy C. G. , Hensor E. , Wakefield R. J. , O'Connor P. J. , Emery P.
Published: November 2006

Objective

More timely and effective therapy for rheumatoid arthritis (RA) has contributed to increasing rates of clinical remission. However, progression of structural damage may still occur in patients who have satisfied remission criteria, which suggests that there is ongoing disease activity. This questions the validity of current methods of assessing remission in RA. The purpose of this study was to test the hypothesis that modern joint imaging improves the accuracy of remission measurement in RA.

Methods

We studied 107 RA patients receiving disease‐modifying antirheumatic drug therapy who were judged by their consultant rheumatologist to be in remission and 17 normal control subjects. Patients underwent clinical, laboratory, functional, and quality of life assessments. The Disease Activity Score 28‐joint assessment and the American College of Rheumatology remission criteria, together with strict clinical definitions of remission, were applied. Imaging of the hands and wrists using standardized acquisition and scoring techniques with conventional 1.5T magnetic resonance imaging (MRI) and ultrasonography (US) were performed.

Results

Irrespective of which clinical criteria were applied to determine remission, the majority of patients continued to have evidence of active inflammation, as shown by findings on the imaging assessments. Even in asymptomatic patients with clinically normal joints, MRI showed that 96% had synovitis and 46% had bone marrow edema, and US showed that 73% had gray‐scale synovial hypertrophy and 43% had increased power Doppler signal. Only mild synovial thickening was seen in 3 of the control subjects (18%), but no bone marrow edema.

Conclusion

Most RA patients who satisfied the remission criteria with normal findings on clinical and laboratory studies had imaging‐detected synovitis. This subclinical inflammation may explain the observed discrepancy between disease activity and outcome in RA. Imaging assessment may be necessary for the accurate evaluation of disease status and, in particular, for the definition of true remission.
Soluble receptor for advanced glycation end products triggers a proinflammatory cytokine cascade via β2 integrin Mac‐1
Authors: Pullerits Rille , Brisslert Mikael , Jonsson Ing‐Marie , Tarkowski Andrej
Published: November 2006

Objective

Receptor for advanced glycation end products (RAGE) is a cell surface molecule that binds a variety of ligands, including high mobility group box chromosomal protein 1 (HMGB‐1), a potent proinflammatory cytokine. RAGE–ligand interaction leads to an inflammatory response. A truncated form of the receptor, soluble RAGE (sRAGE), has been suggested to function as a decoy abrogating cellular activation, but its endogenous activity is not fully understood. We undertook this study to assess the properties of sRAGE in vivo and in vitro and to analyze the role of sRAGE in HMGB‐1–induced arthritis.

Methods

Mice were injected intraarticularly with HMGB‐1 and treated systemically with sRAGE prior to histologic joint evaluation. All animals were subjected to peritoneal lavage to assess the local effect of sRAGE treatment. For in vitro studies, mouse splenocytes were incubated with sRAGE followed by assessment of NF‐κB activation and cytokine production. The chemotactic properties of sRAGE were investigated using in vitro migration assay.

Results

Soluble RAGE was determined to have proinflammatory properties since it gave rise to production of interleukin‐6, tumor necrosis factor α, and macrophage inflammatory protein 2. This effect was triggered by interaction with leukocyte β2 integrin Mac‐1 and was mediated via NF‐κB. Systemic treatment with sRAGE significantly down‐regulated HMGB‐1–triggered arthritis, but the observed effect was due to a deviation of the inflammatory response from the joint to the peritoneal cavity rather than a genuine antiinflammatory effect. Apart from its proinflammatory properties, sRAGE was proven to act as a chemotactic stimulus for neutrophils.

Conclusion

We conclude that sRAGE interacts with Mac‐1, thereby acting as an important proinflammatory and chemotactic molecule.
Isotype distribution of ANTI–CYCLIC citrullinated peptide antibodies in undifferentiated arthritis and rheumatoid arthritis reflects an ongoing immune response

Published: November 2006

Objective

The evolution of the rheumatoid arthritis (RA)–specific anti–cyclic citrullinated peptide (anti‐CCP) antibody response, as measured by the isotypes of anti‐CCP, has not been described. This study was undertaken to determine anti‐CCP isotype usage in patients with undifferentiated arthritis (UA), patients with recent‐onset RA, and patients with RA of long duration.

Methods

IgA, IgM, and IgG subclasses of anti‐CCP were measured by enzyme‐linked immunosorbent assay in serum samples that were obtained from IgG anti‐CCP antibody–positive patients with UA (n = 110) and IgG anti‐CCP antibody–positive patients with RA (n = 152) early after the onset of arthritis. Patients with UA in whom RA developed within 1 year (UA→RA) were compared with patients with UA in whom RA did not develop within 1 year (UA→UA). In addition, baseline serum samples obtained from a subset of patients with RA (n = 64) were compared with sera obtained from the same patients a median of 7 years later.

Results

IgM anti‐CCP was present in early samples from both patients with UA and patients with RA and in followup samples from patients with RA. Several IgG anti‐CCP antibody–positive patients who did not have IgM anti‐CCP early after disease onset did display IgM anti‐CCP later in the course of the arthritis. A diverse pattern of isotype usage was detected in early samples, with a trend toward lower frequencies of all isotypes of anti‐CCP in patients with UA compared with patients with RA and in UA→UA patients compared with UA→RA patients. Levels of all isotypes except IgG1 had decreased after 7 years.

Conclusion

These data indicate development of the anti‐CCP isotype repertoire into full usage early in the course of arthritis. The sustained presence of IgM anti‐CCP indicates ongoing recruitment of new B cells into the anti‐CCP response, reflecting a continuous (re)activation of the RA‐specific anti‐CCP response during the course of anti‐CCP–positive arthritis.
An XMM‐Newton survey of broad iron lines in AGN
Authors: Nandra K. , O'Neill P. M. , George I. M. , Reeves J. N. , Turner T. J.
Published: November 2006

We report on the iron Kα line properties of a sample of Seyfert galaxies observed with the XMM‐Newton EPIC pn instrument. Using a systematic and uniform analysis, we find that complexity at iron‐K is extremely common in the XMM‐Newton spectra. Once appropriate soft X‐ray absorption, narrow 6.4 keV emission and associated Compton reflection are accounted for, ∼75% of the sample show an improvement when a further component is introduced. The typical properties of the broad emission are both qualitatively and quantitatively consistent with previous results from ASCA. The complexity is in general very well described by relativistic accretion disk models. In most cases the characteristic emission radius is constrained to be within ∼50R g, where strong gravitational effects become important. We find in about 1/3 of the sample the accretion disk interpretation is strongly favoured over competing models. In a few objects no broad line is apparent. We find evidence for emission within 6R g in only two cases, both of which exhibit highly complex absorption. Evidence for black hole spin based on the X‐ray spectra therefore remains tentative.

Theoretical aspects of relativistic spectral features
Authors: Karas V.
Published: November 2006

The inner parts of black‐hole accretion discs shine in X‐rays which can be monitored and the observed spectra can be used to trace strong gravitational fields in the place of emission and along paths of light rays. This paper summarizes several aspects of how the spectral features are influenced by relativistic effects. We focus our attention onto variable and broad emission lines, origin of which can be attributed to the presence of orbiting patterns – spots and spiral waves in the disc. We point out that the observed spectrum can determine parameters of the central black hole provided the intrinsic local emissivity is constrained by theoretical models.

Published: November 2006

The transient system SAX J1711.6–3808 was observed by XMM‐Newton during its 2001 outburst, when the source was close to its maximum outburst luminosity. Our observations show that the broad Fe emission line detected in this outburst by In' t Zand et al. (2002) has indeed a relativistic nature, suggesting that SAX J1711.6–3808 harbors a black hole with a high spin parameter. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Discovery of a double peaked Fe emission line in the Cloverleaf quasar H1413+117
Authors: Chartas G. , Eracleous M. , Dai X. , Agol E. , Gallagher S. C.
Published: November 2006

Our spatial and spectral analysis of a recent deep Chandra observation of H1413+117 confirms a microlensing event in a previous Chandra observation of this object performed about 5 years earlier. We present constraints on the structure of H1413+117 based on the time‐scale of this microlensing event. The analysis of the combined spectrum of the images indicates the presence of two emission line peaks at rest‐frame energies of 5.35 keV and 6.32 keV and detected at the ≳97% and ≳99% confidence levels, respectively. The double peaked Fe emission is fit well with an accretion disk‐line model, however, the best‐fit accretion disk model parameters are neither well constrained nor unique. Another possible interpretation of the Fe emission is fluorescent Fe emission from the back‐side of the wind. Additional observations are required to constrain better the model parameters.

Folic acid–containing supplement consumption during pregnancy and risk for oral clefts: A meta‐analysis
Authors: Badovinac Rachel L. , Werler Martha M. , Williams Paige L. , Kelsey Karl T. , Hayes Catherine
Published: November 2006

BACKGROUND: There is equivocal evidence in the published literature that folic acid supplementation during pregnancy may protect against the common congenital anomalies cleft lip with or without cleft palate (CLP) and cleft palate alone (CP). We undertook this meta‐analysis to test the hypothesis that nonsyndromic oral cleft birth prevalences are different for those whose mothers took folic acid–containing supplements and for those whose mothers did not. METHODS: Human studies published in English were identified through MEDLINE, bibliography reviews, and contacting experts in the field. Within strata of prospective and case‐control studies, CLP, CP, and all clefts, respectively, were analyzed using either a fixed or random effects model, as appropriate. We assessed for publication bias using Begg and Mazumdar's rank correlation and Egger's regression‐based tests. RESULTS: Five prospective studies were analyzed, yielding combined relative risks of 0.51 (95% CI: 0.32, 0.95) for CLP, 1.19 (95% CI: 0.43, 3.28) for CP, and 0.55 (95% CI: 0.32, 0.95) for all clefts. Twelve case‐control studies were assessed, which resulted in combined relative risks of 0.77 (95% CI: 0.65, 0.90) for CLP, 0.80 (95% CI: 0.69, 0.93) for CP, and 0.78 (95% CI: 0.71, 0.85) for all clefts. CONCLUSIONS: In aggregate, our results support the hypothesis of a protective effect of folic acid–containing supplement intake during pregnancy on the risk for oral clefts, although this conclusion is tempered by the potential for bias and uncontrolled confounding.

XX – das schlaue Geschlecht? Der “kleine Unterschied” – und seine großen Auswirkungen auf Gehirn und Denken
Authors: Zankl Heinrich
Published: November 2006

Aus der unterschiedlichen genetischen Ausstattung von Mann und Frau resultieren Unterschiede sowohl in der Anatomie als auch in den Funktionen des Gehirns. Eine wichtige Rolle spielen dabei intelligenzbeeinflussende Gene, die sich während der menschlichen Evolution verstärkt auf dem X‐Chromosom angesammelt haben. Insbesondere das Fehlen eines zweiten X‐Chromosoms macht den Mann deshalb anfällig für verschiedene Formen der geistigen Retardierung.

Für die schnelle Zunahme der geistigen Leistungsfähigkeit in der stammesgeschichtlichen Entwicklung des Menschen war vermutlich auch von großer Bedeutung, dass die Frauen schon früh die Intelligenz des Partners als ein wichtiges Auswahlkriterium erkannt haben.
Algen als Notproviant
Authors: Wendler Silke
Published: November 2006

Die Meeresnacktschnecke Phyllodesmium jakobsenae hat eine Strategie entwickelt, die es ihr erlaubt, über Monate hinweg ohne Nahrung auszukommen. Sie entnimmt Weichkorallen, die zu ihrer bevorzugten Nahrung gehören, einzellige Algen und beherbergt diese in ihrem stark verzweigten Mitteldarm, wo sie weiterhin Photosynthese betreiben. Indem Phyllodesmium jakobsenae die Stoffwechselprodukte (Zucker und Aminosäuren) der Algen zur eigenen Ernährung nutzt, kann sie lange Hungerperioden unbeschadet überstehen.
Südafrika: Seepferdchen in Flussmündungen
Authors: Fourie Wendy , Kronberg Inge
Published: November 2006

Wechselnde Körperfarbe, unabhängig voneinander bewegliche Augen und ein kräftiger Wickelschwanz: Diese Merkmale erinnern eher an ein Chamäleon als an einen Fisch. Die Kopfform hat dem Seepferdchen seinen Namen eingebracht. Alle circa 40 bekannten Seepferdchen‐Arten weltweit sind von der IUCN als gefährdet eingestuft, was sowohl am Rückgang ihrer Lebensräume und als auch an gezielter Ausbeutung liegt. Insbesondere die asiatische Medizin nutzt Seepferdchen als zweifelhaftes Aphrodisiakum und in der traditionellen Medizin, Aquarianer und Souvenirjäger verfolgen die bizarren Tiere.

DNA‐Based Phosphane Ligands
Authors: Caprioara Mihaela , Fiammengo Roberto , Engeser Marianne , Jäschke Andres
Published: November 2006

In order to expand the repertoire of DNA sequences specifically interacting with transition metals, we report here the first examples of DNA sequences carrying mono‐ and bidentate phosphane ligands as well as P,N‐ligands. Aminoalkyl‐modified oligonucleotides have been reacted at predetermined internal sites with carboxylate derivatives of pyrphos, BINAP and phosphinooxazoline (PHOX) 2 b–d. Carbodiimide coupling in the presence of N‐hydroxysuccinimide provided the DNA–ligand conjugates in 38–78 % yield. Phosphane‐containing oligonucleotides and their phosphane sulfide analogues were characterized by mass spectrometry (MALDI‐TOF and FT‐ICR‐ESI) and their stability after purification and isolation was systematically investigated. While DNA‐appended pyrphos ligand was quickly oxidized, BINAP and PHOX conjugates showed high stabilities, making them useful precursors for incorporation of transition metals into DNA.
