“BACKGROUNDThe integrated approach of using metal chelate (e.g. Fe(II)EDTA) absorption combined with microbial reduction for nitric oxide (NO) removal has been a frequent topic of much recent study. The present study was undertaken to evaluate simultaneous Fe(II)EDTA-NO and Fe(III)EDTA with Paracoccus denitrificans as a model microorganism.
RESULTSThe experimental results suggested that Fe(III)EDTA reduction was severely inhibited by Fe(II)EDTA-NO while the addition of Fe(III)EDTA could have a positive effect on the reduction of Fe(II)EDTA-NO. Riboflavin, AQDS and vitamin B12 at 0.1
mmol L-1 did not have significant effects on simultaneous reduction of Fe(II)EDTA-NO and Fe(III)EDTA.
Addition of sulfide not only could directly react with selleck Fe(II)EDTA-NO and Fe(III)EDTA but also might play multiple roles in biological Fe(II)EDTA-NO reduction and Fe(III)EDTA reduction. R428 mw The respiratory inhibitor CuCl2 inhibited Fe(II)EDTA-NO reduction as well as Fe(III)EDTA reduction while NaN3 and rotenone showed no measurable effects.
CONCLUSIONSThe present study showed that Fe(II)EDTA-NO reduction and Fe(III)EDTA reduction reacted upon each other. The roles of sulfide were divided in terms of biological and chemical interactions during the simultaneous reduction. CuCl2 could inhibit the simultaneous reduction rates.

“The influence of polarization induced electric fields on the wavelength and the refractive index of intersubband transitions (ISBTs) in AlN/GaN coupled double quantum wells (CDQWs) has been performed by solving Schrodinger and Poisson equations self-consistently. It is found that the intersubband refractive index change of the ISBT between the ground state and the second excited state (1(odd)-2(odd) ISBT) increases, while that of the ISBT between the ground state and the third excited state (1(odd)-2(even) ISBT) decreases with the increase of the polarization induced electric fields. The maximal intersubband refractive index change of
the 1(odd)-2(odd) ISBT can be up to 0.142. The results are finally used to discuss the prospects of nitride quantum wells for electric-optical modulation via cross-phase modulation operating within optical communication wavelength range.

“Background: Our previous studies have reported that activation of Toll-like receptor (TLR) 4 is implicated in the etiology of human dilated cardiomyopathy (DCM). A recent report has demonstrated that let-7i, a member of the let-7 family of cellular microRNAs (miRs) miR-21, miR-126, and miR-155, directly regulate TLR4 expression. The aim of this study was to determine whether let-7i, miR-21, miR-126, and miR-155 are expressed with TLR4 in human DCM, and whether let-7i levels are related to clinical outcomes.
