Abstract

Background
Emergency treatment for patients with a ruptured hepatocellular adenoma is controversial. The aim of this study was to evaluate management with selective arterial embolization.

Methods
The study included 11 consecutive patients treated for ruptured hepatocellular adenomas between 2001 and 2006. After initial haemodynamic support, all patients received selective embolization of branches of the hepatic artery. The primary outcome was effectiveness in stopping the bleeding. Secondary outcomes were complications and changes in tumour size after embolization.

Results
A single embolization brought haemorrhaging under control in ten patients; one patient needed three embolizations. None of the patients required emergency surgery. In the follow-up of 19 (range 7–49) months, no general or hepatobiliary complications were observed. All 25 adenomas, including those without signs of haemorrhaging in the same liver lobe, were either smaller or not detectable on computed tomography or magnetic resonance imaging after embolization, with the median diameter decreasing from 7·0 to 2·5 cm (P &lt; 0·001).

Conclusion
Selective embolization of the hepatic artery is a safe and adequate first approach in the management of patients with haemorrhaging hepatocellular adenomas. Furthermore, arterial embolization reduces the size of adenomas in the liver.

A Flow‐Tube and PERCA Study of Radical Yields in the Ozonolysis of Ethene
Authors: Qi Bin , Yang Hong‐Yan , Wang Zhu‐Qing 
Published: August 2007

AbstractThe production of radicals in the ozonolysis of ethene in air in a flow tube was monitored directly by a chemical amplification instrument at room temperature (298±2) K and 1×105 Pa. The radical yield is 0.50±0.08 (() and found to be independent of CO. The result shows that the indirectly measured radical yields for the ozonolysis of ethene may be underestimated by a factor of 2.
Studies on Thermodynamics Features of the Interaction between Imidacloprid and Bovine Serum Albumin
Authors: Yan Cheng‐Nong , Mei Ping , Guan Zhong‐Jie , Liu Yi 
Published: August 2007

AbstractAt different temperatures, the interactions between imidacloprid (IMI) and bovine serum albumin (BSA) were investigated with a fluorescence quenching spectrum, a synchronous fluorescence spectrum, a three‐dimensional fluorescence spectrum and an ultraviolet‐visible spectrum. The average values of bonding constants (KLB: 3.424×104 L·mol−1), thermodynamic parameters (ΔH: 5.188 kJ·mol−1, ΔG(:−26.36 kJ·mol−1, ΔS: 103.9 J·K−1·mol−1) and the numbers of bonding sites (n: 1.156) could be obtained through Stern‐Volmer, Lineweaver‐Burk and thermodynamic equations. It was shown that the fluorescence of BSA could be quenched for its reactions with IMI to form a certain kind of new compound. The quenching belonged to a static fluorescence quenching, with a non‐radiation energy transfer happening within a single molecule. The thermodynamic parameters agree with ΔH>0, ΔS>0 and ΔGσ<0, suggesting that the binding power between IMI and BSA should be mainly a hydrophobic interaction.

Published: August 2007

AbstractRestrained molecular dynamics simulations were performed to study the binding affinity of the peptide with alkanethiols of different tail‐groups, S(CH2)7CH3, S(CH2)7OH and S(CH2)7COOH, which self‐assembled on Au(111) surface in the presence of water molecules. The curves of binding affinity were calculated by fixing the center of mass of the peptide at various distances from the assembling surface. Simulation results show that the binding affinity is in the order as COOH‐SAMs>OH‐SAMs>CH3‐SAMs, while 100% COOH‐SAMs>5% COOH‐SAMs in concentration. The effects on binding affinity by different tail‐groups were also studied. Results show that the binding affinity between COOH‐SAMs and the peptide is bigger than those of the others and increasing the acidity of COOH‐SAMs will result in stronger attractive power.
Theoretical Study on the Reaction Mechanism of Ketene CH2CO with Isocyanate NCO Radical

Published: August 2007

AbstractThe bimolecular single collision reaction potential energy surface of an isocyanate NCO radical with a ketene CH2CO molecule was investigated by means of B3LYP and QCISD(T) methods. The computed results indicate that two possible reaction channels exist on the surface. One is an addition‐elimination reaction process, in which the CH2CO molecule is attacked by the nitrogen atom at its methylene carbon atom to lead to the formation of the intermediate OCNCH2CO followed by a C–C rupture channel to the products CH2NCO+CO. The other is a direct hydrogen abstraction channel from CH2CO by the NCO radical to afford the products HCCO+HNCO. Because of a higher barrier in the hydrogen abstraction reaction than in the addition‐elimination reaction, the direct hydrogen abstraction pathway can only be considered as a secondary reaction channel in the reaction kinetics of NCO+CH2CO. The predicted results are in good agreement with previous experimental and theoretical investigations.

Published: August 2007

AbstractA homodinuclear complex (NH3CH2CH2CH2NH3)2{Na2[(C6H4O2)2](C6H4O2H)2} (1) has been synthesized by a solution‐based self‐assembly route. It crystallized in monoclinic system with space groupP21/c. Every sodium ion coordinates in a tetragonal prism fashion with two O atoms of a terminal chelating catecholate ligand and three O atoms from two bridging catecholate ligands. Two neighboring NaO5tetragonal prisms are edge‐shared and centrosymmetric with regard to the inversion center to form a binuclear cluster {Na2[(C6H4O2)2](C6H4OOH)2}4−anion. The complex anions were aligned parallelly by π‐π interaction and linked with the protonated 1,3‐propylenediamine through hydrogen bonds which were assembled into a multi‐lamellar structure with channels. The crystal exhibits rectangular geometry with an interior triangle hollow structure under optical microscopy. And the scanning electron microscopy (SEM) indicates that the wall of the tubes shows multi‐lamella morphologies. Further, the transmission electron microscopy (TEM) reveals that the crystal is composed of multi‐lamellar nano‐tubes with diameters less than 100 nm. The molecular structure of the complex was compared with that of its isomer complex2.
A Highly Sensitive Spectrophotometric Assay of Bleomycins Based on the Fading Reaction of Some Halofluorescein Dyes

Published: August 2007

AbstractIn weak acidic medium, anticancer antibiotics bleomycin A5 (BLMA5) and bleomycin A2 (BLMA2) can react with halofluorescein dyes such as erythrosin (Ery), eosin Y (EY), eosin B (EB) and rose bengal (RB) by virtue of electrostatic attraction and hydrophobic force to form the ion‐association complexes, which can result in the fading reactions of four halofluorescein dyes. The maximum fading wavelengths of these four dyes were located at 527 nm for Ery, 515 nm for EY, 517 nm for EB and 546 nm for RB, respectively. The decrements of absorbance ((A) were directly proportional to the concentrations of bleomycin in a certain range. A new method for the determination of bleomycins anticancer drugs based on fading reactions of halofluorescein dyes has been developed. The method was not only highly sensitive but also simple and rapid. The molar absorptivities (ε) ranged from 1.5×105 to 7.5×105 L·mol−1·cm−1. It was applied to determination of the bleomycins in human serum, urine and rabbit serum samples. In this work, the spectral properties and the optimum reaction conditions were investigated. The structure of ion‐association complexes and the reaction mechanism were discussed.

AbstractIn the presence of KF·2H2O, furoylmethyltriphenylarsonium bromide (1a) or thienoylmethyltriphenylarsonium bromide (1b) reacted with 2‐[(un)substituted benzylidene]malononitrile (2) in chloroform at room temperature to give trans‐3,3‐dicyano‐1‐furoyl‐2‐[(un)substituted phenyl]cyclopropane (3a) or trans‐3,3‐dicyano‐1‐thienoyl‐2‐[(un)substituted phenyl]cyclopropane (3b) respectively in good yield with high stereoselectivity. The structures of product 3 were confirmed by IR, MS, 1H NMR, 1H‐1H COSY and microanalysis. The relative configuration of product 3 was determined by 1H‐1H NOESY technique. The mechanism for the formation of product 3 was also proposed.

Published: August 2007

AbstractThe expression of the chimeric BCR/ABL1 fusion gene resulting from t(9;22)(q34;q11) in chronic myelogenous leukemia (CML) is necessary for malignant transformation, but not sufficient to maintain disease progression. The appearance of various chromosomal and molecular alterations in the accelerated and terminal phase of CML is well documented, but evidence for causal relationship is largely lacking. We carried out a genome wide screening at a resolution of 1 Mb of 54 samples at different stages of CML together with 12 CML cell lines and found that disease progression is accompanied by a spectrum of recurrent genome imbalances. Among the most frequent are losses at 1p36, 5q21, 9p21, and 9q34 and gains at 1q, 8q24, 9q34, 16p, and 22q11, all of which were located with higher precision within the genome than previously possible. These genome imbalances are unique to CML cases with clinically manifested or suspected accelerated/blast stage alike, but not seen in chronic phase samples. Previously unrecognized cryptic imbalances occurring within the Ph‐chromosome were also detected, although further scrutiny is required to pin‐point gene involvement and seek association with disease features. Importantly, some of these imbalances were seen in the CD34(+) cells but not in the whole BM samples of patients in accelerated phase. Taken together, these findings highlight the potential of screening CD34(+) cells for genome wide imbalances associated with disease progression. Finally, the numerous single copy number variations recorded, many unique to this cohort of patients, raise the possible association of genome polymorphism and CML. © 2007 Wiley‐Liss, Inc.
Modelling of meteorological conditions at an urban scale for the PUMA campaigns

Published: August 2007

AbstractIn this paper, a comparison of modelled and observed surface wind and temperature for two campaigns of the PUMA (Pollution of Urban Midlands Atmosphere) project is presented. The Regional Atmospheric Modelling System (RAMS) was configured for the West Midlands conurbation (WM), UK, to have two nested grids with a mesh size of 2 km for the inner grid which is embedded in the outer grid with a mesh size of 8 km. Statistical evaluation of the model results against observational data of wind speed, direction and temperature was conducted. In general, the model's performance is better in the summer campaign than in the winter campaign. The results suggest that the quality of the prediction is sensitive to whether or not cloud cover is captured by the model under winter conditions. Although the topography of the region is relatively flat, some spatial patterns of wind and temperature may exist under stagnant conditions during the summer and winter seasons. Under summer conditions, the spatial patterns are associated with convective eddies or rolls during daytime, while under winter conditions, the spatial patterns are closely linked to stability and topography. The modelled results of such winter conditions for the inner grid reveal subtle spatial patterns at a scale smaller than 10 km near hills and valleys with differences in elevation of a few hundred metres.
