Varicella‐zoster virus in cerebrospinal fluid at relapses of multiple sclerosis
Authors: Sotelo Julio , Martínez‐Palomo Adolfo , Ordoñez Graciela , Pineda Benjamin
Published: February 2008

Objective

Recent studies in peripheral blood mononuclear cells (PBMCs) have indicated that exacerbations of multiple sclerosis (MS) could be associated with the reactivation of latent varicella‐zoster virus (VZV).

Methods

Ultrastructural observations for viral particles were made by electron microscopy in cerebrospinal fluid (CSF) from 15 MS patients during relapse, 19 MS patients during remission, and 28 control subjects. Initial findings were reproduced in a confirmation cohort. In addition, DNA from VZV was quantified by real‐time polymerase chain reaction in PBMCs and CSF from a large number of MS patients (n = 78).

Results

We found by electron microscopy the presence of abundant viral particles identical to VZV in CSF obtained from MS patients within the first few days of an acute relapse. In contrast, viral particles were not seen in CSF samples from MS patients in remission or from neurological control subjects. Also, DNA from VZV was present in CSF and in PBMCs during relapse, disappearing in most patients during remission. The mean viral load was 542 times greater in CSF at relapse than in CSF at remission and 328 times greater in CSF at relapse than in PBMCs at relapse.

Interpretation

The ultrastructural finding of viral particles identical to VZV, together with the simultaneous presence of large quantities of DNA from VZV in the subarachnoid space, almost restricted to the periods of exacerbation, as well as its steady diminution and eventual disappearance from clinical relapse to clinical remission are surprising and constitute the strongest evidence to support the participation of VZV in the pathogenesis of MS.

Neurohospitalists: An emerging model for inpatient neurological care
Authors: Josephson S. Andrew , Engstrom John W. , Wachter Robert M.
Published: February 2008

Over the past decade, the hospitalist model has become a dominant system for the delivery of general adult and pediatric inpatient care. Similar forces, including national mandates to improve safety and quality and intense pressure to safely reduce length of hospital stays, that led to the remarkable growth of hospitalist medicine are now exerting pressure on neurologists. A neurohospitalist model, in which inpatient neurology specialists deliver high‐quality and efficient care to neurology patients, is emerging to meet these challenges. Benefits of this system may include more frequent, timely neurology consultations in the hospital and emergency department, as well as improved quality of inpatient neurological education for residents and medical students. Challenges will involve defining the relationship of neurohospitalists with primary stroke centers, the economic feasibility of such neurohospitalist systems, and how to train members of this new field. A neurohospitalist model of care is an emerging idea in neurology that would overcome many regulatory, educational, and economic challenges facing neurologists; further research is needed to gauge the effects of this innovative approach.

Tailored functionalization of low‐density polyethylene surfaces
Authors: Goddard J. M. , Hotchkiss J. H.
Published: February 2008

Surface‐functionalization chemistries were optimized to tailor the surface chemistry of polyethylene, and this made covalent attachment of bioactive molecules possible. This concept has relevance in biomaterials, biosensors, textiles, and active food‐packaging applications. Clean polyethylene films were subjected to chromic acid oxidation to introduce carboxylic acids. A range of functional groups, including amine, aldehyde, thiol, and hydroxyl, were then introduced to the surface of the oxidized films with functionalized crosslinking agents and covalent bioconjugation chemistries. The quantity of functional groups was further increased by subsequent grafting of polyfunctional agents such as polyethylenimine and poly(acrylic acid). The number and type of functional groups were quantified by contact‐angle, dye‐assay, attenuated total reflectance/Fourier transform infrared, and X‐ray photoelectron spectroscopy analyses. We optimized chemistries to introduce a variety of functional groups to the surface of low‐density polyethylene in numbers ranging from several picomoles per centimeter squared to tens of nanomoles per centimeter squared. A range of bioactive compounds, including antimicrobials, antibodies, oligonucleotides, cell precursors, drugs, peptides, enzymes, and synthetic biomimetic agents, can be covalently bound to these functional groups in the development of nonmigratory biofunctionalized polymers. © 2008 Wiley Periodicals, Inc.

Nonequilibrium nanoblend membranes for the pervaporation of benzene/cyclohexane mixtures
Authors: Okeowo Oluwasijibomi , Nam Sang Yong , Dorgan John R.
Published: February 2008

Immiscible blends of polymers were cast from solution, and the rate of evaporation was controlled relative to the rate of phase separation to produce different morphologies; upon crosslinking, stable nonequilibrium nanoblends were realized. This process of forced assembly produced useful membrane materials that could be designed for solubility selectivity with the group contribution methodology. Crosslinked ternary blends of nitrile butadiene rubber (NBR), poly(methyl methacrylate) (PMMA), and a tercopolymer of ethylene oxide/epichlorohydrin/allyl glycidyl ether (Hydrin) were examined for use in the separation of benzene from cyclohexane by pervaporation. For a 50 : 50 wt % benzene/cyclohexane feed, blend 811 (containing 80 wt % NBR, 10 wt % Hydrin, and 10 wt % PMMA) gave a separation factor of 7.3 and a normalized flux of 28 kg μm/m2 h; such a performance is unmatched in the literature, with the flux being very high for the reported separation factor. Among the samples tested, the flux of the membrane increased as the amount of NBR in the ternary blend decreased; however, the separation factor was not largely affected. Blended samples showed no sign of deformation after 48 h at the operating temperature as compared to pure NBR, which did show evidence of creep. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
General and more precise relationships between molecular weight, blend ratio, and melt index of binary polyethylene blends
Authors: Ghasemi S. M. , Sadeghi G. Mir Mohamad
Published: February 2008

Simpler, cheaper, and fast methods to characterize material properties are important in industrial plants. One of these properties is molecular weight which is measured generally by size exclusion chromatography, an expensive method and also limited for polyolefins which have few solvents. Melt flow index (MFI) measurement is simple, cheap, and rapid that could be a considerable method to estimate of polymers. In this work, mathematical correlation between MI* (a new defined MFI), first melt dropping of blend (t1), weight fraction (wi) and
in binary polyethylene blends, PE/PE wax, has been investigated by using a new device. Results show that relationships MI* and t1 with wi of the blended materials follow a modified Arrhenius equation (Wong equation) and also new non‐Arrhenius equations for prediction of MI of blends have been investigated. We proposed a modified molecular weight () for Bremner and Rudin's equation (Bremner et al., J Appl Polym Sci 1990, 41, 1617), which is used in 1/MI* and t1 correlations with molecular weight of polymer. © 2008 Wiley Periodicals, Inc.

Measurement of the condensation temperature of nanosilica powder organically modified by a silane coupling agent and its effect evaluation
Authors: Liu Xiao , Zhao Suhe
Published: February 2008

The proper condensation temperatures of nanosilica powder modified by silane coupling agents such as 3‐methacryloxypropyl trimethoxy silane (MEMO), [3‐(2‐aminoethyl)aminopropyl] trimethoxy silane (AMMO), and bis[3‐(triethoxysilyl)propyl] disulfide (TESPD) were measured with Fourier transform infrared. Moreover, the structure and properties of solution‐polymerized styrene–butadiene rubber (SSBR) filled with nanosilica powder that was organically modified by the three silane coupling agents at different temperatures were investigated. The results showed that the proper condensation temperatures of nanosilica powder modified by MEMO, AMMO, and TESPD were about 80, 80, and 100°C, respectively. Compared with SSBR filled with silica powder, SSBR filled with silica powder modified by a silane coupling agent exhibited not only better filler‐dispersion and mechanical properties but also lower internal friction loss in a selected range of strains. Furthermore, when the organic modification was carried out at the proper condensation temperature, the improvement of the modification effect became more obvious. Among these silane coupling agents, AMMO presented the most remarkable modification effect for nanosilica. The mechanism of modification for silica powder and its enhancement of the properties of SSBR were examined. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Synthesis and characterization of new optically active segmented poly(amide imide urethane)s based on different diacids via an isocyanate route
Authors: Mallakpour Shadpour , Khani Marziyeh , Rafiemanzelat Fatemeh
Published: February 2008

A new class of optically active poly(amide imide urethane)s (PAIUs) was synthesized via a two‐step diisocyanate route. In the first step, 4,4′‐methylenebis(phenyl isocyanate) (MDI) was reacted with different diacids to produce an isocyanate‐terminated oligo(amide imide). The chain extension of the previous hard segment with poly (ethylene glycol) diols with a molecular weight of 400 was the second step for furnishing a series of new PAIUs. N‐Trimellitylimido‐L‐leucine was used as a diacid monomer for polycondensation reactions. Polymerization reactions were performed without any catalysts or with pyridine or dibutyltin dilaurate as a catalyst. The optimized reaction conditions were used for the reaction of N‐trimellitylimido‐L‐isoleucine, N‐trimellitylimido‐L‐methionine, N‐trimellitylimido‐S‐valine, and N‐trimellitylimido‐L‐phenylalanine as diacid monomers with MDI. The resulting multiblock copolymers had inherent viscosities of 0.25–0.78 dL/g. These multiblock copolymers were optically active, thermally stable, and soluble in amide‐type solvents. All these polymers were fully characterized with Fourier transform infrared spectroscopy, 1H‐NMR and ultraviolet–visible spectroscopy, specific rotation measurements, and thermal analyses. Some structural characteristics and physical properties of these new optically active PAIUs were examined. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Study on the microstructure of EPDM/NBR blend by positron annihilation spectroscopy
Authors: Mostafa N.
Published: February 2008

Positron annihilation lifetime and Doppler broadening of annihilation radiation techniques were employed to investigate the relationship between free‐volume hole properties and miscibility of ethylene propylene diene monomer (EPDM)/acrylonitrile butadiene rubber (NBR) blends. It has been found that there were positive and negative deviations in free‐volume hole size (τ3) and concentration (I3) as well as S‐parameter from linear relationship of initial polymers indicating the immiscibility of the blend. The broadening in free‐volume hole distribution by increasing NBR content in EPDM/NBR blend confirm the results obtained by finite term analysis. From the filling effect of silica on free‐volume properties of EPDM/NBR (75/25) blend, it has been found that the addition of silica up to 50 phr is the most promising concentration for electrical application. Furthermore, correlations were established between free‐volume hole size and fraction combined with the results of electrical (dielectric constant and dielectric loss) and mechanical (stress at yield and strain at yield) properties. © 2008 Wiley Periodicals, Inc.

Auf dem Weg zu einer CO2‐freien Wärmeversorgung – Probleme mit den Wegweisern?
Authors: Rabenstein Dietrich
Published: February 2008

Es wird geprüft, wie gut sich die geplante EnEV 2009, die Hamburgische Klimaschutzverordnung sowie die Erneuerbare‐Energien‐Wärmegesetze auf Bundesebene und in Baden‐Württemberg dazu eignen, die beabsichtigten Klimaschutzziele zu erreichen. Ein sparsamer Umgang mit erneuerbarer Wärme ist bisher nicht ausreichend abgesichert. Ersatzmaßnahmen sind ökonomisch noch attraktiver als Solarpflichten. CO2‐Emissions‐Grenzen wären vorteilhafter als Primärenergiebedarfs‐Grenzen. Eine Zusammenfassung der Energieeinsparverordnung und des Erneuerbare‐Energien‐Wärmegesetzes wird vorgeschlagen.

Analytical Model for Predicting Thermal Bridge Effects due to Vacuum Insulation Panel Barrier Envelopes
Authors: Tenpierik Martin , van der Spoel Wim , Cauberg Hans
Published: February 2008

Because of a necessity for sustainability and thus for a reduction of the amount of primary energy generated with fossil fuels, vacuum insulation panels (VIP) have recently caught the attention of practitioners in the building industry. The reduction of layer thickness may be considered among the most promising features for large‐scale application of VIPs in buildings. The high barrier laminate (or casing) with relatively high thermal conductivity envelops the core material, thus introducing a thermal bridge at the panel edges and corners. Especially for barrier laminates containing ‘thick’ metal foils, the thermal bridge effect needs to be considered thoughtfully. In this contribution analytical models are presented which on the one hand allow rapid estimation of the VIP's overall thermal performance and on the other hand show the influence of material and geometric parameters on this performance. The analytical models are validated through numerical simulations.
Risk of new aneurysms after surgery for popliteal artery aneurysm
Authors: Ravn H , Wanhainen A , Björck M
Published: February 2008

Background

The risk of developing a new aneurysm after surgery for popliteal artery aneruysm (PAA) is not well known. The aim was to study this risk in a cohort of patients.

Methods

A total of 571 patients who had primary operation for PAA (717 legs) between 1987 and 2002 were identified from the Swedish Vascular Registry (Swedvasc). Of these, 190 patients were re-examined by ultrasonography after a median of 7 (range 2·9–18·7) years.

Results

The number of patients with at least one aneurysm in addition to the PAA was 108 (56·8 per cent) at the index operation and 131 (68·0 per cent) at re-examination. The overall number of aneurysms increased by 41·8 per cent, from 244 to 346. Among the 82 patients who had an isolated PAA at the index operation, 23 developed a new aneurysm; these patients tended to be older (P = 0·004). Bilateral PAA at the index operation was associated with a later development of abdominal aortic aneurysm (P = 0·004). Age (P = 0·004) and hypertension (P = 0·012) at the time of the index operation were associated with multianeurysm disease at any time. Six (4·3 per cent) of 138 legs treated by venous bypass grafts had developed a graft aneurysm by the time of re-examination. No normal arterial segment developed an aneurysm that required surgery within 3 years.

Conclusion

The development of new aneurysms was common in patients with a PAA; lifelong surveillance may be warranted.
Through‐Bond Excited Energy Transfer Mediated by an Amidinium–Carboxylate Salt Bridge in Zn–Porphyrin Free‐Base Porphyrin Dyads
Authors: Otsuki Joe , Kanazawa Yuki , Kaito Atsuko , Shafiqul Islam D.‐M. , Araki Yasuyuki , Ito Osamu
Published: February 2008

Excited energy‐transfer processes were investigated for a supramolecular Zn–porphyrin free‐base porphyrin dyad, ZnPA‐2⋅FbPC‐2, in which β‐octaalkylated meso‐diarylporphyrins are connected through an amidinium–carboxylate salt bridge. The rate of energy transfer in the dyad (1.3×109 s−1) is substantially slower than that in the previously reported dyad, ZnPA‐1⋅FbPC‐1 (4.0×109 s−1), in which meso‐tetraarylporphyrins are connected through the same amidinium–carboxylate salt bridge. The Förster‐type mechanism can explain only minor parts of these rates (3.3×108 and 5.1×108 s−1, respectively). Thus, Dexter‐type through‐bond energy transfer may be invoked. Indeed, bridge‐mediated electronic processes would be favored in ZnPA‐1⋅FbPC‐1 over ZnPA‐2⋅FbPC‐2 on the basis of steric and electronic factors. Sterically, the phenyl groups in ZnPA‐2 and FbPC‐2 are more closely perpendicular to the porphyrin planes than those in ZnPA‐1 and FbPC‐1. Electronically, the energy and symmetry of the occupied frontier orbitals should favor ZnPA‐1⋅FbPC‐1 over ZnPA‐2⋅FbPC‐2 in terms of electronic interactions through the bridge. Therefore, the observed trend (ZnPA‐1⋅FbPC‐1>ZnPA‐2⋅FbPC‐2), consistent with these considerations, lends further support to the through‐bond mechanism. Thus, the amidinium–carboxylate salt bridge is effective in mediating through‐bond energy transfer even though the bond is noncovalent.
Modular Phosphite–Oxazoline/Oxazine Ligand Library for Asymmetric Pd‐Catalyzed Allylic Substitution Reactions: Scope and Limitations—Origin of Enantioselectivity
Authors: Diéguez Montserrat , Pàmies Oscar
Published: February 2008

A library of phosphite–oxazoline/oxazine ligands L1–L15 a–h has been synthesized and screened in the Pd‐catalyzed allylic substitution reactions of several substrate types. These series of ligands can be prepared efficiently from easily accessible hydroxyl amino acid derivatives. Their modular nature enables the substituents/configurations in the oxazoline/oxazine moiety, alkyl backbone chain and in the biaryl phosphite moiety to be easily and systematically varied. By carefully selecting the ligand components, therefore, high regio‐ and enantioselectivities (ee values up to 99 %) and good activities have been achieved in a broad range of mono‐ and disubstituted linear hindered and unhindered liner and cyclic substrates. The NMR studies on the Pd–π‐allyl intermediates provide a deeper understanding about the effect of the ligand parameters on the origin of enantioselectivity. It also indicates that the nucleophilic attack takes place predominantly at the allylic terminal carbon atom located trans to the phosphite moiety.
