Induction of Ring‐Shaped Calcium Oxalate Patterns by Boundaries between Liquid Expanded Phase and Liquid Condensed Phase in Langmuir‐Blodgett Film
Authors: WAN Mu‐Hua , ZHANG Sheng , ZHENG Hui , OUYANG Jian‐Ming
Published: May 2008

The formation of calcium oxalate kidney stones was related to injuries of renal epithelial membranes. The liquid condensed (LC) domains in Langmuir‐Blodgett (LB) film of dipalmitoylphosphatidylcholine (DPPC) were used as a model system to induce crystal growth of urinary mineral calcium oxalate monohydrate (COM). The circular defective boundaries between the LC and liquid expanded (LE) phases of the DPPC monolayer could provide much more nucleating sites for crystallization of COM crystals. It induced ring‐shaped or solid circular patterns of COM crystals on hydrophobic quartz substrates depending on the crystallization time.

Published: May 2008

A magnetic photocatalyst TiO2/NiFe2O4 (TN) with typical ferromagnetic hysteresis was prepared by a sol‐gel method, which is easy to be separated from a slurry‐type photoreactor under the application of an external magnetic field, being one of promising photocatalysts for wastewater treatment. The analysis of XRD indicated that the highly dispersed NiFe2O4 nanoparticles prevented the formation of rutile phase to some extent. A transmission electron microscope (TEM) was used to characterize the structure of the photocatalyst, indicating that the NiFe2O4 nanoparticles highly dispersed among TiO2 nanoparticles. The prepared photocatalyst showed high photocatalytic activity for the degradation of methyl orange in water. The degradation results revealed that the NiFe2O4 nanoparticles played the role of recombination centre of photogenerated electrons and holes for the TN photocatalyst, which gave rise to the decrease in photocatalytic activity. Moreover, the experiment on recycled use of TN demonstrated a good repeatability of the photocatalytic activity.

Published: May 2008

Thermal decomposition of tetra(piperidinium) octamolybdate tetrahydrate, [C5H10NH2]4[Mo8O26]·4H2O, was investigated in air by means of TG‐DTG/DTA, DSC, TG‐IR and SEM. TG‐DTG/DTA curves showed that the decomposition proceeded through three well‐defined steps with DTA peaks closely corresponding to mass loss obtained. Kinetics analysis of its dehydration step was performed under non‐isothermal conditions. The dehydration activation energy was calculated through Friedman and Flynn‐Wall‐Ozawa (FWO) methods, and the best‐fit dehydration kinetic model function was estimated through the multiple linear regression method. The activation energy for the dehydration step of [C5H10NH2]4[Mo8O26]·4H2O was 139.7 kJ/mol. The solid particles became smaller accompanied by the thermal decomposition of the title compound.
Application of PC‐ANN to Acidity Constant Prediction of Various Phenols and Benzoic Acids in Water
Authors: HABIBI‐YANGJEH Aziz , ESMAILIAN Mahdi
Published: May 2008

Principal component regression (PCR) and principal component‐artificial neural network (PC‐ANN) models were applied to prediction of the acidity constant for various benzoic acids and phenols (242 compounds) in water at 25 °C. A large number of theoretical descriptors were calculated for each molecule. The first fifty principal components (PC) were found to explain more than 95% of variances in the original data matrix. From the pool of these PC's, the eigenvalue ranking method was employed to select the best set of PC for PCR and PC‐ANN models. The PC‐ANN model with architecture 47‐20‐1 was generated using 47 principal components as inputs and its output is pKa. For evaluation of the predictive power of the PCR and PC‐ANN models, pKa values of 37 compounds in the prediction set were calculated. Mean percentage deviation (MPD) for PCR and PC‐ANN models are 18.45 and 0.6448, respectively. These improvements are due to the fact that the pKa of the compounds demonstrate non‐linear correlations with the principal components. Comparison of the results obtained by the models reveals superiority of the PC‐ANN model relative to the PCR model.

Published: May 2008

Electrospray ionization mass spectrometry (ESI‐MS) was utilized to perform monitoring of the intermediates in the reaction of 1,2,3‐trisubstituted electron‐deficient cyclopropane derivatives, cis‐1‐thien‐2′‐oyl‐2‐(p‐subustituted phenyl‐6,6‐dimethyl)‐5,7‐dioxaspiro[2.5]‐4,8‐octadiones, with methanol. Key intermediates, either cationic or protonated forms of neutral species, were intercepted and characterized by ESI‐MS and its tandem version (ESI‐MS/MS). Therefore, the mechanism of the ring‐opening process for electron‐deficient cyclopropane derivatives was fully confirmed by the intermediates monitored.

BACKGROUND.

The epidermal growth factor receptor (EGFR) inhibitor cetuximab is active in recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN). The activity of cetuximab was compared with that of commonly used treatments in this setting.

METHODS.

All patients had recurrent and/or metastatic SCCHN and had progressed on cisplatin‐ or carboplatin‐based chemotherapy. Efficacy data from 3 prospective studies (n = 278 patients) that administered cetuximab as a single agent (n = 103 patients) or combined with either cisplatin/carboplatin (n = 96 patients) or cisplatin (n = 79 patients) were compared with the results from a retrospective study of patients who received various second‐line treatments (all treatments including best supportive care only, n = 151 patients; chemotherapy, n = 43 patients). Safety data considered were only those from the cetuximab studies.

RESULTS.

Over the 3 cetuximab trials, overall response rates from 10% to 13% and disease control rates from 46% to 56% were observed. The median time to disease progression ranged between 2.2 months and 2.8 months, and the median overall survival ranged between 5.2 months and 6.1 months. No patients who progressed on cetuximab alone responded to additional platinum. These survival data compared favorably with those from the retrospective study (median survival, 3.4 months [n = 151 patients] and 3.6 months [n = 43 patients]). Cetuximab‐based treatments generally were tolerated well, and cetuximab did not increase the side effects associated with platinum therapy.

CONCLUSIONS.

Cetuximab has the potential to prolong survival in patients with recurrent and/or metastatic SCCHN who fail on platinum therapy compared with various second‐line therapies. Cetuximab did not increase the toxicities associated with chemotherapy. The results obtained by treatment with cetuximab alone after platinum failure did not appear to differ from the results obtained by reintroducing platinum in combination with cetuximab.

The Dual Mode Microwave Afterglow Apparatus for Measuring the Electron Temperature Dependence of the Electron‐Ion Recombination
Authors: Mikuš O. , Lukáč P. , Morva I. , Morvová M. , Foltin V.
Published: May 2008

Three dual mode microwave apparatus (one using S ‐band and two using X ‐band) have been developed to determine ambipolar diffusion and electron‐ion recombination rates under conditions such that Tgas = 300K and Te is varied from 300 K to 6300 K, in the afterglow period of the dc glow discharge. TheTM010 cylindrical cavity (in S ‐band) and TM011 open cylindrical cavity (X ‐band) are used to determine the electron density during the afterglow period and a non‐resonant waveguide mode is used to apply a constant microwave heating field to the electrons. To test the properties of the apparatus the neon afterglow plasma has been investigated. At Te = 300 K a value of α (Ne+2) = (1.7± 0.2) × 10–7cm3/s is obtained which is in good agreement with values of other investigators. Also similar variations of α as T–0.4e (S ‐band) and as T–0.42e (X ‐band) obeyed over the range 300 ≤ Te ≤ 6300K are in good agreement with some other previous measurements. The simplicity of the X‐band microwave apparatus also allows the measurements of the gas temperature dependency and the study of electron attachment and may be used simultaneously with optical or mass spectrometry investigations.

Published: May 2008

A VHF H2 plasma was produced with the multi rod electrode at high pressure and the plasma parameters were measured as a function of pressure for different VHF powers at 60 MHz. It was found that when the pressure is increased, the ion saturation current peaks at certain pressure and finally decreases at high pressures, while the electron temperature is around 10 eV. The wall potential at high pressure was lower than the values estimated from the electron temperature using the probe theory. Furthermore, the anomalous reduction of the electron saturation current was observed. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Kinetic Modeling of Self‐Generated Magnetic Fields by Transverse Plasmons in the Relativistic Regime
Authors: Li X.Q. , Liu S.Q. , Tao X.Y.
Published: May 2008

The magnetic field generation by relativistic transverse plasmons is investigated using a kinetic description. It is shown that the behavior of self‐generated magnetic fields can be described by nonlinear coupling equations. Numerical results show that a magnetic field self‐generated by relativistic laser irradiation may collapse, leading to enhancement of the magnetic field up to ten Gigagauss in extremely small volumes, which is coincident with the estimated magnetic field strengths in experiments on the critical surface.
