Preparation and selective binding characterization of Bisphenol A imprinted polyethersulfone particles
Authors: Yang Kaiguang , Li Bingquan , Zhou Hui , Ma Jiaojiao , Bai Pengli , Zhao Changsheng 
Published: August 2007

AbstractBisphenol A (BPA) imprinted polyethersulfone (PES) particles were prepared for the recognition of BPA by means of phase inversion method. During the preparation of the BPA‐imprinted particles, acetone, ethanol and acetone/ethanol solutions were used to extract the template BPA molecules. The SEM morphology and the recognition experiments suggested that the acetone/ethanol provided an efficient way to extract the BPA from the imprinted PES particles. The binding and recognition ability for the imprinted particles disappeared under alkali condition, and they recovered as soon as possible when the solution changed from alkali condition to neutral or acid condition. With the addition of Na+, Mg2+, and Cl−, the binding amounts for the imprinted particles and nonimprinted particles were not changed heavily, which suggested the potential application of the particles in seawater. In the BPA/BPA analogue mixed solution, the imprinted particles showed selectivity for the template molecules BPA. The FTIR results suggested that the PES and BPA interacted through hydrogen bonds. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
Synthesis, properties, and gas permeation performance of cardo poly(arylene ether sulfone)s containing phthalimide side groups
Authors: Chen Guang , Zhang Xiaosa , Zhang Suobo , Chen Tianlu , Wu Yonglie 
Published: August 2007

AbstractNovel bisphenol monomers (1a‐d) containing phthalimide groups were synthesized by the reaction of phenolphthalein with ammonia, methylamine, aniline, and 4‐tert‐butylanilne, respectively. A series of cardo poly(arylene ether sulfone)s was synthesized via aromatic nucleophilic substitution of 1a‐d with dichlorodiphenylsulfone, and characterized in terms of thermal, mechanical and gas transport properties to H2, O2, N2, and CO2. The polymers showed high glass transition temperature in the range 230–296°C, good solubility in polar solvents as well as excellent thermal stability with 5% weight loss above 410°C. The most permeable membrane studied showed permeability coefficients of 1.78 barrers to O2 and 13.80 barrers to CO2, with ideal selectivity factors of 4.24 for O2/N2 pair and 28.75 for CO2/CH4 pair. Furthermore, the structure–property relationship among these cardo poly(arylene ether sulfone)s had been discussed on solubility, thermal stability, mechanical, and gas permeation properties. The results indicated that introducing 4‐tert‐butylphenyl group improved the gas permeability of polymers evidently. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
Structure and properties of cellulose nanocomposite films containing melamine formaldehyde
Authors: Henriksson Marielle , Berglund Lars A. 
Published: August 2007

AbstractFilms of high Young's modulus and low density are of interest for application as loudspeaker membranes. In the present study nanocomposite films were prepared from microfibrillated cellulose (MFC) and from MFC in combination with melamine formaldehyde (MF). The prepared materials were studied with respect to structure as well as physical and mechanical properties. Studies in SEM and calculation of porosity showed that these materials have a dense paper‐like structure. The moisture sorption isotherms were measured and showed that moisture content decreased in the presence of MF. Mechanical properties were studied by dynamical mechanical thermal measurements as well as by tensile tests. Cellulose films showed an average Young's modulus of 14 GPa while the nanocomposites showed an average Young's modulus as high as 16.6 GPa and average tensile strength as high as 142 MPa. By controlling composition and structure, the range of properties of these materials can extend the property range available for existing materials. The combination of comparatively high mechanical damping and high sound propagation velocity is of technical interest. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
Malnutrition after oesophageal cancer surgery in Sweden
Authors: Martin L , Lagergren J , Lindblad M , Rouvelas I , Lagergren P 
Published: August 2007

Abstract

Background
Oesophageal cancer resection carries a risk of nutritional disorders. The aim of this study was to estimate weight change after surgery in a population-based setting and to identify nutritional problems that might correlate with weight loss.

Methods
Data were collected through the Swedish Esophageal and Cardia Cancer Register, a nationwide registry of oesophageal cancer surgery. Patients who underwent oesophageal cancer surgery between 2001 and 2004 were followed up until April 2005, and data on patient and tumour characteristics and surgical treatment were collected. Six months after surgery the patients were asked to complete a questionnaire about weight and a health-related quality of life questionnaire (European Organization for Research and Treatment of Cancer (EORTC QLQ-C30) with an oesophageal-specific module (EORTC QLQ-OES18)).

Results
The response rate to the questionnaire was 76·9 per cent and weight change in 226 patients was analysed. Six months after operation 63·7 per cent had lost more than 10 per cent of their preoperative BMI, and 20·4 per cent had lost more than 20 per cent. Appetite loss, eating difficulties and odynophagia were significantly linked to postoperative weight loss, whereas dysphagia or reflux did not correlate with malnutrition.

Conclusion
Malnutrition is a considerable problem after oesophagectomy, and is linked to appetite loss, eating difficulties and odynophagia.
The value of radio‐anatomical features on non‐contrast CT scans in localizing the source in aneurysmal subarachnoid haemorrhage

Published: August 2007

AbstractIdentification of the source of subarachnoid haemorrhage (SAH) can be a challenge in the presence of multiple aneurysms. This study was carried out to assess whether radioanatomical features on noncontrast enhanced computerised tomography (CT) scans may be of value in localizing ruptured intracranial aneurysms. The diagnostic CT scans of 56 consecutive patients, investigated for SAH with cerebral angiography, over a period of six months were available for review. Various radioanatomical features were assessed: (1) pattern of subarachnoid blood (e.g. predominant site and location near major vessel bifurcation), (2) presence of intraparenchymal haematoma, (3) presence of aneurysm contour and (4) hydrocephalus. On the basis of the findings an estimation of the anatomical location of the source of bleeding was made and then compared with the angiogram findings to which the reviewer was blinded. The location of the aneurysm was correctly identified in 89.5% of cases. Careful analysis of the pattern of bleeding was essential for the successful localization of the aneurysm in all these cases. The presence of an aneurysm contour was also associated with correct identification of the source of bleeding (χ2 = 6.067, P = 0.02). Our findings suggest that radioanatomical features on CT scans in SAH can be a valuable aid in the correct identification of the location of the ruptured aneurysm. This would be of particular significance in the presence of multiple intracranial aneurysms. Clin. Anat. 20:618–623, 2007. © 2007 Wiley‐Liss, Inc.
Metal‐Binding Properties of a Dicysteine‐Containing Motif in Protein Tyrosine Kinases

Published: August 2007

AbstractStudying the structural consequences of the direct binding of arsenite, cadmium, cobalt, nickel, and lead to a number of protein tyrosine kinases led to the discovery of the metal‐binding properties of a dicysteine‐containing motif in the C‐terminal (CT) lobe of the kinases. Of all the synthesized peptides derived from different domains of c‐Src and Csk, only peptides based on a dicysteine‐containing motif located in the CT lobe of the kinase domain—CPESLHDLMCQC and CPESLHDLMC in c‐Src, and CPPAVYDVMKNC in Csk—exhibited significant conformational changes in the presence of all metals, as shown by circular dichroism (CD) analyses. Furthermore, CD analysis of natural enzymes c‐Src, Csk, Fyn, c‐Abl, Lck, EGFR, and c‐Src domains containing the CT lobe in the presence of metals showed a significant concentration‐dependent conformational change. ICP‐MS, 113Cd NMR, 33S NMR, and/or molecular modeling studies of CPESLHDLMC and CPPAVYDVMKNC confirmed the binding between the free sulfhydryl groups of the cysteine residues and CdII or AsIII. UV‐titration studies suggested a high‐affinity interaction between CdII and AsIII and the peptides (Kd values in the range of 0.6–18.3 nM).
Standardization of line‐scan NIR imaging systems
Authors: Liu Zheng , Yu Honglu , MacGregor John F. 
Published: August 2007

AbstractA simple and easy to use method is proposed for standardizing NIR imaging systems for differences among detectors in the charge‐coupled device (CCD) array and illumination unevenness. The standardization equations are then used to pre‐treat NIR image data to reduce the systematic errors introduced by a line‐scan NIR imaging system. The method requires only easily available homogeneous standards with relatively uniform spectral response. The effectiveness of the standardization in reducing the pixel‐to‐pixel biases and other systematic effects is illustrated with examples, and the improved sensitivity in results obtained from a multivariate image analysis (MIA) based on multi‐way principal component analysis (MPCA) is demonstrated.
