摘要

We present for the first time the use of deferiprone as a non-toxic complexing agent for the determination of iron by sequential injection analysis in pharmaceuticals and food samples. The method was based on the reaction of Fe( III) and deferiprone in phosphate buffer at pH 7.5 to give a Fe(III)-deferiprone complex, which showed a maximum absorption at 460 nm. Under the optimum conditions, the linearity range for iron determination was found over the range of 0.05-3.0 mu g mL(-1) with a correlation coefficient (r(2)) of 0.9993. The limit of detection and limit of quantitation were 0.03214 mL(-1) and 0.055 mu g mL(-1), respectively. The relative standard deviation (%RSD) of the method was less than 5.0% (n = 11), and the percentage recovery was found in the range of 96.0-104.0%. The proposed method was satisfactorily applied for the determination of Fe(III) in pharmaceuticals, water and food samples with a sampling rate of 60 h(-1). (C) 2015 Elsevier B.V.

Emerging Roles of the Iron Chelators in Inflammation

Alessandra Di Paola, Chiara Tortora, Maura Argenziano, Maria Maddalena Marrapodi, Francesca Rossi

Summary: Iron is a crucial element for mammalian cells and its alteration could lead to the onset of disorders. Iron chelation has been proposed as a novel therapeutic strategy to counteract inflammation in autoimmune and inflammatory diseases. Several iron chelators, such as deferiprone, deferoxamine, deferasirox, and Dp44mT, have anti-inflammatory effects. Eltrombopag has been reported to reduce inflammation by chelating iron and modulating iron efflux.

Free iron rather than heme iron mainly induces oxidation of lipids and proteins in meat cooking

Yafei Zhang, Xiaojing Tian, Yuzhen Jiao, Yang Wang, Juan Dong, Ning Yang, Qinghua Yang, Wei Qu, Wenhang Wang

Summary: This study investigated the relationship between different forms of iron and the oxidation of lipids and proteins in meat. The results showed that free iron was the main oxidizing substance, and the addition of exogenous heme slightly increased meat oxidation. The study also found that lipid oxidation was more serious than protein oxidation. Controlling the generation of free iron and free iron from heme is a potential approach for reducing oxidative damage in meat cooking.

Summary: In this research, a novel dynamic migration model is proposed to better describe the dynamic characteristics of lithium-ion batteries under different aging states by adjusting battery parameters in realtime. A novel chaotic firefly-particle filtering method is proposed, which uses the behavior of fireflies in nature to simulate particle optimization and find a new optimal solution through chaotic mapping. Compared with traditional particle filtering algorithm, the proposed algorithm improves the state-of-charge and state-of-health estimation accuracy by 1.48% and 0.38% respectively under Hybrid Pulse Power Characterization condition, and by 0.67% and 0.63% respectively under Beijing bus dynamic stress test condition. The proposed battery model and algorithm are of great significance in improving the condition monitoring quality of the battery management system.

Summary: In this paper, an improved algorithm based on multi-hidden layer long short-term memory (MHLSTM) neural network and sub-optimal fading extended Kalman filtering (SFEKF) is proposed for synthetic state of charge (SoC) estimation.

Summary: The recycling of waste mandarin peels into biochar (MRBC) has been used as a high performance and cost-effective adsorbent for treating polluted wastewater effluents. Batch adsorption studies were conducted to analyze the adsorption competency of MRBC on two dyes, methylene blue (MB) and basic fuchsin (BF), either in individual solutions or binary combinations. The results showed that MRBC was capable of effectively removing a high percentage of both dyes. However, the adsorption capacity decreased when the dyes were combined. The cost estimation of MRBC production and wastewater treatment indicated that both were relatively low.

Non-invasive analysis of reference glass and historical mosaic tesserae by means of reflectance infrared spectroscopy

Maria Cristina Caggiani, Germana Barone, Paolo Mazzoleni

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
