6) across the anion-exchange membrane (AEM) was very low, under https://www.selleckchem.com/products/SB-202190.html similar experimental conditions. Under optimum experimental conditions, separation of GLU from GLU-LYS mixture was achieved with moderate energy consumption (12.9 kWh kg(-1)), high current efficiency (CE) (65%) and 85% recovery of GLU.
CONCLUSIONS: On the basis of the electro-transport rate of AA and membrane selectivity, it was concluded that the separation of GLU-LYS mixture was possible at pH 8.0, because of the oppositely charged
nature of the two amino acids due to their different pi values. Moreover, any type of membrane fouling and deterioration in membrane conductivity was ruled out under experimental conditions. This work clearly demonstrates the great potential of EMP for industrial applications. (C) 2010 Society of Chemical Industry”
“A correct function of adipocytes in connection with cellular fatty acid loading and release is a vital aspect of energy homeostasis; dysregulation of these reactions can result in obesity and type 2 diabetes mellitus. In addition, adipocytes have been proposed to play a major role in preventing lipotoxicity by removing excess fatty acids from the circulation and converting them into triglycerides and thus decreasing the exposure of other cells to their potentially harmful
effects. We report here that the addition of a-tocopheryl phosphate (but not a-tocopherol) to NIH3T3-L1 preadipocytes transcriptionally activates a set of genes TRB3 (Tribbles Selleck INCB024360 Homolog 3), Sestrin-2
(SESN2), and Insulin-Induced Selleckchem Sapanisertib Gene 1 (INSIG1)] potentially preventing fat accumulation in these cells. In contrast, in differentiated adipocytes, a-tocopheryl phosphate is responsible for the transcriptional inhibition of the same genes, possibly facilitating fat uptake and storage. In conclusion, it appears that in proliferating preadipocytes a-tocopheryl phosphate foils fat accumulation, whereas in adipocytes it enhances it. These processes may be relevant in the regulation of excess fat accumulation and in prevention of lipotoxicity. (C) 2012 International Union of Biochemistry and Molecular Biology, Inc.”
“BACKGROUND: Unutilized dyes present a significant environmental problem. Recently, biological activated carbon has been used extensively for the removal of gas and wastewater pollutants but its use in dye removal is still limited. The system provides simultaneous adsorption of pollutants and biodegradation/biotransformation of pollutants in a single reactor, and showed high efficiency and a long working life.
RESULTS: The adsorption of Reactive Black 5 by three selected adsorbents, F400, bone char and bamboo activated carbon, was studied. The relationships between adsorption, desorption, bioregeneration and the effect of nutrient on dye adsorption was assessed. The potential value of using adsorbents as a microbial support in the biodegradation of Reactive Black 5 was investigated.
