During Stage II (20-80 days), higher proportions of Fe3O4 in scale in experiments with no or low NaOCl dosages restrained the corrosion process and presented smaller corrosion current. Subsequently, the ductile iron surface became passivated and the difference of various NaOCl dosages affecting corrosion and scaling process turned to be negligible during Stage III (80-90 days). A negative linear relationship between the proportion of stable scale component and the corrosion current density was established. Besides the direct corrosion reaction with iron substrate, NaOCl dosing was accompanied by an increase in pH and calcium carbonate precipitation potential values, which affected the early period corrosion and scaling phenomenon greatly. Effect of in-bag dielectric barrier discharge cold plasma (IB-DBD-CP) on the keeping quality of Asian sea bass slices (ASBS) packaged under different gases during refrigerated storage at 4 °C was studied. ASBS without and with IB-DBD-CP treatment packaged under the gas combination of argon and oxygen (1090) (gas A) or the mixtures of carbon dioxide, argon and oxygen (603010) (gas B) and the control (kept in air) were monitored for quality changes up to 18 days. ASBS treated with IB-DBD-CP, regardless of gas composition, had lower microbial loads than those without treatment and the control (p 15 days at 4 °C. BACKGROUND Regular transfusions are the gold standard therapy for β-thalassemia and are often complicated by secondary-iron overload and alloimmunization. We assessed the frequency of regulatory T cells (Tregs) and the levels of cytokines implicated in Th-responses in 49 patients 33 TDT and 16 NTDT in order to investigate the contribution of transfusion and its complications on immune responses. MATERIALS AND METHODS Tregs were characterized with flow cytometry. Soluble IL-4, IL-6, IL-10, IL-17A, and TGF-β1 were assessed by ELISA. Clinical data including alloimmunization, age of onset of transfusion splenectomy hepatitis B and C infection, iron overload assessment with MRI T2* (liver and heart) were recorded from the patients' files. RESULTS Tregs levels, IL-6, IL-10, TGFβ and serum ferritin were higher in the TDT compared to the NTDT group (all p  less then  0.05). There was no difference of Tregs and circulating cytokines in patients in correlation with the extend of iron overload (assessed by T2*liver), the type of chelator or the development of alloantibodies. DISCUSSION Tregs levels are higher in TDT patients compared to NTDT, a difference which could be ascribed to transfusion. Tregs levels and the cytokines analyzed may play little role in alloimmunization and are not impacted by the extend of iron overload. Photo-fermentative hydrogen production, the new energy production alternative, was greatly enhanced by formed biofilm. To understand the mechanism of enhancement, the intracellular proteome and extracellular polymeric substance (EPS)i during biofilm formation were investigated in this work. Experimental results indicated that a possible and effective altered system could transfer light to hydrogen. Proteins were significantly regulated, for example those related with nitrogenase, flagellin, EPS transportation and DNA duplication were up-regulated while those concerned photosystem were down-regulated. It revealed these changes of proteins contributed to positive activity of key enzymes, improved communication system and increased total light utilization efficiency thus leading to enhanced capacity of hydrogen production. Besides above metabolic changes inside the cells, EPS secreted by the bacteria played an important role in hydrogen production and its yield decided the release of hydrogen. CCT251545 When EPS descended to a lower concentration during biofilm formation, it meant carbon source for EPS synthesis was reduced, and more energy and reducing power could be transferred into hydrogen energy. More importantly, this work found that c
