    Abstract: Acrylamide ( AA ) is of concern worldwide because of its neurotoxicity, genotoxicity and reproductive/developmental toxicity. Consequently, methods for minimizing AA formation during food processing are vital. RESULTS In this study, the formation and elimination of AA in an asparagine/glucose low‐moisture model system were investigated by response surface methodology. The effect of garlic powder on the kinetics of AA formation/elimination was also evaluated. The AA content reached a maximum level (674.0 nmol) with 1.2 mmol of glucose and 1.2 mmol of asparagine after heating at 200 °C for 6 min. The AA content was greatly reduced with the addition of garlic powder. Compared to without garlic powder, an AA reduction rate of 43% was obtained with addition of garlic powder at a mass fraction of 0.05 g. Garlic powder inhibited AA formation during the generation‐predominant kinetic stage and had no effect on the degradation‐predominant kinetic stage. The effect of garlic powder on AA formation in bread and bread quality was also investigated. Adding a garlic powder mass fraction of 15 g to 500 g of dough significantly ( P 〈 0.05) reduced the formation of AA (reduction rate of 46%) and had no obvious effect on the sensory qualities of the bread. CONCLUSION This study provides a possible method for reducing the AA content in bread and other heat‐treated starch‐rich foods. © 2015 Society of Chemical Industry

    Theoretical insight into the photodeactivation pathway of the tetradentate Pt (II) complex with different inductive substituents

    Abstract: Density functional theory (DFT) and time‐dependent density functional theory (TD‐DFT) both were used to explore the impacts of different inductive substituents on the photophysical properties, radiative/nonradiative processes and photodeactivation mechanism for the Pt (II) complex with novel spiro‐arranged tetradentate ligand. Spectrum simulations show that the electron donor methoxyl (‐OCH 3 ) group can cause the emission wavelength to red‐shift but have little effect on the absorption spectrum. In the simulation of the radiative decay process for the tetradentate Pt (II) complex, the singlet‐triplet splitting energy is reduced by the introduction of substituents with strong electron‐releasing capability (i.e., from the original trifluoromethyl (‐CF 3 ) group to ‐OCH 3 group), accompanied with a lower radiative rate constant ( k r ). The analyses of non‐radiative decay processes show that the substitution of ‐OCH 3 group on azole rings reduces the energy barriers of thermally activated non‐radiative photodeactivation pathway, which in turn increases the temperature‐dependent non‐radiative rate constants ( k nr (T)). In addition, the substitution of ‐CF 3 by ‐OCH 3 group slightly weakens molecular rigidity and enhances the Huang‐Rhys factor, but decreases the SOC between the triplex excited (T) state and the ground (S 0 ) state. Thereby, the two complexes may have the similar temperature‐independent non‐radiative rate constant ( k nr ’). This work offers theoretical guidance for the design and optimization of the efficient organic light emitting diode (OLED) materials based on the structure of tetradentate Pt (II) complexes.

    Abstract: A series of active coke‐based adsorbents from different sources, treated with acid‐base, modified by metal compounds and calcined at different temperatures were investigated for SO 2 removal from flue gas. RESULTS The desulfurization performance of the pure active coke was low, but it was improved after treatment with acid‐base, especially HNO 3 . The active coke loaded with 8% Na 2 CO 3 and 7% Cu(NO 3 ) 2 and calcined at 250–350 °C was best for SO 2 removal. Compared with the untreated active coke, the time for which A‐H‐8‐7 maintained DE at 90% increased from 4 min to 40 min and the value of DE of A‐H‐8‐7 increased from 0.131 mmol g ‐1 to 0.526 mmol g ‐1 . The acid‐base treatment was effective in forming rich pore structures and HNO 3 treatment formed carbonyl groups which favored desulfurization. Sodium and copper modification made a large number of unsaturated groups and chelating bonds formed and sodium and copper elements were dispersed adequately and existed as different compounds in the active coke. The active ingredients for desulfurization were different at different calcination temperatures. Cu(NO 3 ) 2 tended to break down into Cu 2 O at higher temperatures. Most adsorption products were sulfate species (SO 4 2‐ ) which combined with supported copper and sodium and then formed Na 2 Cu(SO 4 ) 2 . CONCLUSION Active coke loaded with 8% Na 2 CO 3 and 7% Cu(NO 3 ) 2 and calcined at 250–350 °C showed good performance for SO 2 removal. © 2014 Society of Chemical Industry

    Olfactomedin 1 negatively regulates NF‐κB signalling and suppresses the growth and metastasis of colorectal cancer cells

    Abstract: Uncontrolled growth and distant metastasis are hallmarks of colorectal cancer ( CRC ), but the mechanisms are poorly understood. Olfactomedin 1 ( OLFM1 ), a member of the olfactomedin domain‐containing protein family, plays an important role in the development of neurogenic tissues. Recently, OLFM1 deregulation was frequently observed in several cancers, and it was induced in colon cell lines after treatment with the demethylating agent 5‐aza‐2'‐deoxycytidine. However, the function of OLFM1 in CRC remains unknown. In this study, we reanalysed published microarray data and found that OLFM1 was significantly down‐regulated in primary CRC samples compared to adjacent non‐cancerous tissues. The results of immunohistochemistry indicated that decreased OLFM1 expression was significantly associated with lymph node status ( p = 0.023), distant metastasis ( p 〈 0.001), and AJCC / TNM stage ( p = 0.013), and CRC patients with low OLFM1 expression had consistently poor overall survival ( OS ; p 〈 0.001) and progression‐free survival ( PFS ; p 〈 0.001). Further analysis demonstrated that OLFM1 was epigenetically silenced in CRC tissues and cell lines via promoter hypermethylation. Overexpression and knockdown of OLFM1 attenuated and increased, respectively, CRC cells' proliferation, migration, and invasion in vitro and metastasis to the lung and liver in vivo . Mechanistically, the promotion of growth and metastasis of CRC cells by silencing of OLFM1 was associated with the activation of the non‐canonical NF‐κB signalling pathway. OLFM1 interacted with NF‐κB ‐inducing kinase ( NIK ; MAP3K14 ) and repressed the phosphorylation of its downstream substrate Ikappa B kinase alpha ( IKKα ). OLFM1 expression was negatively correlated with the phosphorylation level of IKKα in CRC tissue samples. Knockdown of NIK impaired the ability of OLFM1 to repress NF‐κB signalling, cell growth or migration. Thus, OLFM1 may be a valuable biomarker and therapeutic target for CRC patients.

    Whole exome and target sequencing identifies MAP2K5 as novel susceptibility gene for familial non‐medullary thyroid carcinoma

    Abstract: What's new? Although the genotype–phenotype for familial medullary thyroid carcinoma (FMTC) is well studied, only a few low susceptibility risk loci have been identified for familial non‐medullary thyroid carcinoma (FNMTC). Here, the authors screened and identified a novel susceptibility gene, MAP2K5 , as a contributor to FNMTC. The data revealed that MAP2K5 variants A321T or M367 T can activate the MAP2K5–ERK5 pathway, alter downstream gene expression, and subsequently induce thyroid epithelial cell malignant transformation. The study thus highlights the potential application of MAP2K5 for molecular diagnosis as well as better clinical management for deleterious MAP2K5 mutation carriers.

    Abstract: Copper‐supported activated carbon (Cu‐SAC) was studied for the simultaneous removal of SO 2 , NO, and CO 2 in different operating conditions. The effects of Cu loading, adsorption temperature, O 2 concentration, and relative humidity (RH) were studied. The experimental results showed that Cu‐SAC containing 9.8% of Cu had the best removal activity of SO 2 , NO, and CO 2 . The activity dropped with the further increase of Cu loading. Higher temperatures were not in favor of simultaneous adsorption of SO 2 , NO, and CO 2 . The performances of the removal of SO 2 and NO improved obviously in the presence of O 2 . Water vapor could improve the adsorption performance of SO 2 , but higher RH was bad for the adsorption performance of SO 2 . The adsorption of NO and CO 2 was deterred in the presence of water vapor. Cu‐SAC was shown to be a potential sorbent for simultaneous adsorption of SO 2 , NO, and CO 2 . © 2015 American Institute of Chemical Engineers Environ Prog, 34: 1044–1049, 2015

    Enhancing the Photovoltaic Performance of Triplet Acceptors Enabled by Side‐Chain Engineering

    Abstract: Triplet excitons have both longer lifetimes and diffusion lengths than singlet excitons due to the nature of triplet excitons, which is expected to increase the photocurrent and further improve the performance of organic solar cells (OSCs). However, the working mechanism of triplet excitons in OSCs is not clearly clarified. Therefore, it is urgent to develop new triplet acceptors for in‐depth understanding. Herein, a series of acceptors ( BT n ‐4Cl ) are synthesized by fine‐tuning of the side‐chain branch positions. The generation of triplet excitons of BT n ‐4Cl is confirmed by the time‐resolved photoluminescence (TRPL) spectra, magnetophotocurrent (MPC) experiment, and electron paramagnetic resonance (EPR) spectra. The effects of side‐chain engineering on the optoelectronic properties, packing behaviors, energy losses, charge transport properties, spin lifetimes of triplet polarons, and blend film morphologies are systematically studied. These results show that D18: BT3‐4Cl ‐based OSCs possess the best power conversion efficiency (PCE) of 17.31% due to lower energy losses, less recombination losses, more balanced charge carrier mobilities, longer spin–lattice ( T 1 ) relaxation time, and more favorable morphology. This work enhances the understanding of the structure–property relationship for high‐performance triplet acceptors.
