Published: April 2006

AbstractThe reaction of poly(allyl azide) (PAA; number‐average molecular weight = 1800 g/mol) with N‐phenyl maleimide, 4,4′‐bis(maleimidodiphenyl) ether, 4,4′‐(bismaleimidodiphenyl) sulfone, and 1,6‐bismaleimido hexane is described in this article. As indicated by Fourier transform infrared studies, the azido group reacted with the highly electron‐deficient olefinic bond of N‐phenyl maleimide or bismaleimides in a 3 + 2 cycloaddition reaction under mild reaction conditions. The curing of PAA with bismaleimides (10–30 phr) was monitored with differential scanning calorimetry. In freshly prepared samples of PAA and bismaleimides, a broad exothermic transition was observed in the temperature range of 150–280°C and could be attributed to the loss of N2 from PAA and the curing of bismaleimides. The heat of the exothermic reaction (ΔH) depended on the structure and composition and was in the range of 800–1413 J/g. Isothermal heating in an air oven at 40°C (2 days) followed by 60°C (5–6 days) resulted in the conversion of a sticky, viscous liquid into an elastic, nonsticky material. No significant difference in the ΔH values of uncured and cured samples was observed, and this indicated the reaction of fewer azido groups with the bismaleimides (dipolarophiles). In the thermogravimetry traces, a mass loss was indicated in the temperature range of 130–280°C due to the loss of nitrogen from the azido group. © 2006 Wiley Periodicals, Inc.

Published: April 2006

AbstractPolyaniline doped with (±)‐camphor sulfonic acid was blended with polyvinyl chloride/nitrile rubber. The thermoplastic blend was characterized for its conductivity, mechanical and dynamic mechanical properties, and microwave response. The blend was found to be compatible in nature. Loss component of relative permittivity increased with polyaniline content. Storage modulus increased with polyaniline content, whereas tan δ showed decline. © 2006 Wiley Periodicals, Inc.

Changes of fluorescence color in novel poly(azomethine) by the acidity variation
Authors: Kil Choi Myon , Lim Kim Hoi , Hack Suh Dong 
Published: April 2006

AbstractA novel polymer, poly(4,4′‐oxydiphenylenemethylidynenitrilo‐2,5‐dihexyloxy‐1,4‐phenylenenitrilomethyli‐ dyne) (POPNM), with a azomethine structure, containing long alkoxy side chains, was synthesized by the polycondensation of 2,5‐bis(hexyloxy)terephthalaldehyde with 4,4′‐oxydianiline. It displayed acid‐sensory properties as colorimetric and fluorescent transducers to the strong acid analytes because of the protonation of an imine group in the compound. To examine the sensitivity to the acid, the effect of absorption and fluorescence of the polymer was investigated by simply adding trifluoroacetic acid into a chloroform solution of the polymer, and as a result, the multiple colors of fluorescence were sharply changed. Increasing the amount of the acid, the maximum absorption bands of fluorescence spectra were bathochromically shifted from 470 to 570 nm and, then, treating the pyridine as a base, they were recovered. A polymer film containing both the polymer and a photoacid generator (PAG) was prepared by semi‐interpenetrating network polymerization method. When the polymer film was exposed to UV in the presence of PAG through a photomask, well‐resolved fluorescent image patterns were readily obtained. © 2006 Wiley Periodicals, Inc.

The long‐term but not the short‐term antiviral effectof IFN‐α depends on Flt3 ligand and pDC
Authors: Vollstedt Sabine , O'Keeffe Meredith , Ryf Beat , Glanzmann Bettina , Hochrein Hubertus , Suter Mark 
Published: April 2006

AbstractThe cooperation between IFN‐α/β and FL, the ligand of Fms‐like tyrosine kinase 3 (Flt3), plays an important role in the defense against herpes simplex virus type 1 (HSV‐1) in neonates. Treatment of neonatal mice with recombinant IFN‐α has a short‐term, FL‐independent and a long‐term, FL‐dependent protective effect against HSV‐1. In mice lacking FL, neonatal resistance against HSV‐1 is very low and DC numbers in the spleen are reduced. The treatment of these mice with rIFN‐α at day 6 resulted in an increased resistance against infection with HSV‐1 at day 7. In C57BL/6 mice, treatment with rIFN‐α at birth induced both FL and plasmacytoid DC (pDC), resulting in enhanced resistance against HSV‐1 at day 7. In contrast, in mice lacking FL, IFN‐α treatment at birth did not influence the splenic cell composition and had no effect on viral protection. The transfer of pDC to mice lacking FL enhanced viral resistance. Therefore, the induction and function of pDC, normally controlled by IFN‐α/β and FL, are decisive for viral resistance in neonatal mice.
Optimizing cancer immunotherapy trials: Back to basics
Authors: Stevenson Freda K , Rice Jason 
Published: April 2006

AbstractAttempts to raise effective immunity against cancer are benefiting from information on the nature of the immunity involved and its regulation and, perhaps, now it is time to step back and define our approach in molecular terms prior to clinical testing. Although there are immunological differences between mice and patients, results from murine studies are encouraging early ‘translation’ of concepts to the clinic and it is vital to take immunological principles emerging from mice into clinical vaccine design. One is the requirement to break tolerance against over‐expressed self‐antigens, a potentially risky procedure but necessary for several cancer targets. A study in this issue of the European Journal of Immunology attempts to do this by using xenogeneic antigens, albeit with variable outcome. The unstated goal is to activate T‐cell help but this can be achieved more effectively by harnessing a predictable anti‐microbial repertoire. The second issue lies in the delivery of antigen. One strategy is "prime/boost" using DNA priming and boosting with a viral vector; however, this induces blocking immunity against viral proteins, and must be used judiciously. There are other physical methods to increase immunity such as electroporation, which can itself be used in ‘prime/boost’ sequence. These twin problems of engagement of T‐cell help and delivery of adequate antigen can now be addressed by applying immunological logic to cancer vaccines.See accompanying article http://dx.doi.org/10.1002/eji.200535514
