Establishing a Clean‐quality Indicator System for Evaluating Reclaimed Land in the Antaibao Opencast Mine Area, China
Authors: Bi R. T. , Bai Z. K. , Li H. , Shao H. B. , Li W. X. , Ye B. Y. 
Published: August 2010

AbstractThis article discusses the existing problems associated with reclaimed land in the area of the Antaibao Opencast Coal Mine, which is located in the semi‐arid region of northwest China. The following eight indicators of the suitability of the reclaimed land were developed based on the theory of soil genesis and landscape ecology: the thickness of the effective soil layer, composition of the soil surface, vegetation index, types of covering vegetation, slope of the terrain, time of reclamation, area of the evaluation unit, and the shape index of the evaluation unit. The suitability evaluation indexes of the reclaimed land were determined using the 3S technology and fuzzy evaluation methods, which revealed that the suitability of the reclaimed land in the study area could be divided into six grades and two categories, land suitable for farming, and land suitable for trees or grass. The suitability evaluation indicators and evaluation methods developed to evaluate reclaimed land in this study will be beneficial to the large‐scale rapid monitoring and the effective management of reclaimed land in the opencast mine area.
An Assessment on Metal Sources by Multivariate Analysis and Speciation of Metals in Soil Samples Using the BCR Sequential Extraction Procedure
Authors: Tokalıoğlu Şerife , Yılmaz Vedat , Kartal Şenol 
Published: August 2010

AbstractThe concentrations of Cr, Mn, Fe, Ni, Cu, Zn, and Pb metals in soil samples (N = 21) were determined by flame atomic absorption spectrometry. The modified Community Bureau of Reference (BCR) sequential extraction procedure (three‐step) was used in order to evaluate mobility, availability, and persistence of heavy metals in soil samples taken from an agricultural area in Erciyes University Campus. The operationally defined fractions isolated using the BCR procedure were: acid extractable, reducible, and oxidizable. The mobility sequence based on the sum of the BCR sequential extraction stages was: Mn (70.2%) > Pb (62.9%) > Ni (26.7%) > Cr (15.4%) > Zn (14.4%) > Cu (12.9%) > Fe (1.24%). Multivariate statistical analysis was used to define the possible origin of heavy metals in soils. Correlation analysis, principal component analysis (PCA), and cluster analysis (CA) were applied to the data matrix to evaluate the analytical results and to identify the possible pollution sources of heavy metals. PCA results revealed that the sampling area was mainly influenced from three sources, namely natural, airborne emissions from domestic heating and traffic.
Probing the Peptidylglycine α‐Hydroxylating Monooxygenase Active Site with Novel 4‐Phenyl‐3‐butenoic Acid Based Inhibitors

Published: August 2010

AbstractSpecific inhibition of the copper‐containing peptidylglycine α‐hydroxylating monooxygenase (PHM), which catalyzes the post‐translational modification of peptides involved in carcinogenesis and tumor progression, constitutes a new approach for combating cancer. We carried out a structure–activity study of new compounds derived from a well‐known PHM substrate analogue, the olefinic compound 4‐phenyl‐3‐butenoic acid (PBA). We designed, synthesized, and tested various PBA derivatives both in vitro and in silico. We show that it is possible to increase PBA affinity for PHM by appropriate functionalization of its aromatic nucleus. Compound2 d, for example, bears ameta‐benzyloxy substituent, and exhibits better inhibition features (Ki=3.9 μM,kinact/Ki=427 M−1 s−1) than the parent PBA (Ki=19 μM,kinact/Ki=82 M−1 s−1). Docking calculations also suggest two different binding modes for PBA derivatives; these results will aid in the development of further PHM inhibitors with improved features.
New Halogenated Water‐Soluble Chlorin and Bacteriochlorin as Photostable PDT Sensitizers: Synthesis, Spectroscopy, Photophysics, and in vitro Photosensitizing Efficacy

Published: August 2010

AbstractChlorin and bacteriochlorin derivatives of 5,10,15,20‐tetrakis(2‐chloro‐5‐sulfophenyl)porphyrin have intense absorptions in the phototherapeutic window, high water solubility, high photostability, low fluorescence quantum yield, long triplet lifetimes, and high singlet oxygen quantum yields. Biological studies revealed their negligible dark cytotoxicity, yet significant photodynamic effect against A549 (human lung adenocarcinoma), MCF7 (human breast carcinoma) and SK‐MEL‐188 (human melanoma) cell lines upon red light irradiation (cutoffλ<600 nm) at low light doses. Time‐dependent cellular accumulation of the chlorinated sulfonated chlorin reached a plateau at 2 h, as previously observed for the related porphyrin. However, the optimal incubation time for the bacteriochlorin derivative was significantly longer (12 h). The spectroscopic, photophysical, and biological properties of the compounds are discussed in relevance to their PDT activity, leading to the conclusion that the bacteriochlorin derivative is a promising candidate for future in vivo experiments.
Overexpression of CD151 as an adverse marker for intrahepatic cholangiocarcinoma patients

Published: August 2010

AbstractBACKGROUND:Previous studies have indicated that CD151, a hydrophobic protein, forms a functional complex with the proto‐oncogene that encodes an N‐methyl‐N′‐nitro‐N‐nitroso‐guanidine (MET) protein (c‐Met), and CD151 overexpression reportedly is involved in metastasis/invasion of several tumors. The objective of the current study was to investigate the expression and role of CD151 and/or c‐Met in intrahepatic cholangiocarcinoma (ICC).METHODS:Sixty ICC tissues with matched nontumorous tissues and 20 normal liver tissues were used to analyze CD151 expression at the level of messenger RNA (mRNA) and protein. Then, the expression of CD151 in an ICC cell line was interrupted using a specific lentiviral‐mediated small hairpin RNA (shRNA)‐CD151, and the role of CD151 in the proliferation, metastasis, and invasion of ICC cells was assessed. The expression of CD151/c‐Met was examined further by immunohistochemistry in a tissue microarray (TMA) that included 140 samples of ICC, and the prognostic role of CD151 and/or c‐Met in ICC was evaluated in Kaplan‐Meier and Cox regression analyses.RESULTS:The expression of CD151 in ICC tissues was much higher than that in nontumorous samples and normal liver; and, after the down‐regulation of CD151, HCCC‐9810 cells had decreased capability for metastasis/invasion in vitro. CD151 overexpression was correlated significantly with larger tumors, poor differentiation, multiple nodular, microvascular/bile duct invasion, and lymphatic metastasis (P<.05). The postoperative 2‐year and 5‐year overall survival (OS) rates for patients with low CD151 expression (<50% tumor staining) and/or low c‐Met expression (<20% tumor staining) were higher than the rates for patients with high CD151 expression (≥50% tumor staining) and/or high c‐Met expression (≥20% tumor staining). Multivariate analysis revealed that CD151 overexpression and c‐Met overexpression were independent prognostic markers for ICC.CONCLUSIONS:Overexpression of CD151 was implicated in metastasis/invasion of ICC, and both CD151 overexpression and c‐Met overexpression may be potential molecular therapeutic targets for ICC.
