The ability of Shewanella decolorationis S12 to obtain energy for growth by coupling the oxidation of various electron donors to dissimilatory azoreduction was investigated. This microorganism can reduce a variety of azo dyes by use of formate, lactate, pyruvate, or H(2) as the electron donor. Furthermore, strain S12 grew to a maximal density of 3.0 x 10(7)(More)
Shewanella decolorationis S12 was able to reduce various azo dyes in a defined medium with formate, lactate, and pyruvate or H2 as electron donors under anaerobic conditions. Purified membranous, periplasmic, and cytoplasmic fractions from strain S12 analyzed, respectively, only membranous fraction was capable of reducing azo dye in the presence of electron(More)
Reduction and biodegradation mechanisms of naphthylaminesulfonic azo dye amaranth using a newly isolated Shewanella decolorationis strain S12 were investigated. Under anaerobic conditions, amaranth was reduced by strain S12, and a stoichiometric amount of two reduction products RP-1 and RP-2 were generated. UV/visible spectrophotometric and high performance(More)
BACKGROUND Necrotizing enterocolitis (NEC) is the leading cause of neonatal gastrointestinal mortality; effective interventions are lacking with limited understanding of the pathogenesis of NEC. The importance of Toll-like receptor 4 (TLR4) signaling in NEC is well documented; however, the potential mechanisms that regulate enterocyte inflammation and(More)
The interaction of a new intramolecular charge transfer probe, namely 4'-dimethylamino-2,5-dihydroxychalcone (DMADHC), with calf thymus DNA has been studied. Compared to the spectral characteristics of the free form in aqueous solution, the fluorescence of DMADHC enhanced dramatically accompanying a blueshift of the emission maxima in the presence of DNA.(More)
OBJECTIVE To summarize experiences and discuss the reasons for postlaparoscopic indirect inguinal hernia recurrence in children. PATIENTS AND METHODS From June 2008 to June 2013, 6120 laparoscopic inguinal hernia repairs were performed in our hospital involving 5382 males and 738 females. The average age was 3.1 years. When pneumoperitoneum was(More)
Propranolol, a lipophilic nonselective β-blocker, has recently been reported to be the treatment of choice for select types of infantile hemangiomas (IHs). Atenolol is a hydrophilic, selective β1-blocker and therefore may be not associated with side effects attributable to β2-adrenergic receptor blockade and lipophilicity. However, the efficacy and safety(More)

To deal with a kind of uncertainties existed in the complex industry processes, a new design method of robust proportional- integral- derivative (PID) controller based on coevolutionary particle swarm optimization was presented in the paper. The parameters tuning problem for robust PID controller was reduced to solve a maximum-minimum problem. A co-(More)
