Monascus pigments are secondary metabolites of Monascus species and are mainly composed of yellow pigments, orange pigments and red pigments. In this study, a larger proportion of Monascus yellow pigments could be obtained through the selection of the carbon source. Hydrophilic yellow pigments can be largely produced extracellularly by Monascus ruber CGMCC 10910 under conditions of high glucose fermentation with low oxidoreduction potential (ORP). However, keeping high glucose levels later in the culture causes translation or a reduction of yellow pigment...

Surgical removal with radical prostatectomy has been a cornerstone for the treatment of prostate cancer and is associated with level one evidence for survival advantage compared to watchful waiting. Since the first structured robotic program was launched in 2000, robot-assisted radical prostatectomy (RARP) has had a rapid diffusion and surpassed its open (ORP) and laparoscopic (LRP) counterparts in the United States and is progressively expanding in other countries. Interestingly, this common acceptance of RARP was initially driven in the paucity of robust clinical evidence...

Internal micro-electrolysis (IE) coupled with Fenton oxidation (IEF) was a very effective technology for copper (Cu)-ethylenediaminetetraacetic acid (EDTA) wastewater treatment. However, the mechanisms of Cu(2+) removal and EDTA degradation were scarce and lack persuasion in the IEF process. In this paper, the decomplexation and removal efficiency of Cu-EDTA and the corresponding mechanisms during the IEF process were investigated by batch test. An empirical equation and the oxidation reduction potential (ORP) index were proposed to flexibly control IE and the Fenton process, respectively...

Prostate cancer (PCa) has been stratified in different risk categories according to the patient prognosis. High-risk disease is formerly known for increased risk of metastasis and lethality, requiring complex treatments. Recently, surgery was highlighted to have a pivotal role for the treatment of such cases, even as monotherapy. Formerly open radical prostatectomy (ORP) was adopted for most patients with high-risk PCa, however robot assisted radical prostatectomy (RARP) emerged as a reasonable option since it proved to provide optimal outcomes for low and intermediate-risk PCa...

Interaction between old, corroded iron pipe surfaces and bulk water is crucial to the water quality protection in drinking water distribution systems (WDS). Iron released from corrosion products will deteriorate water quality and lead to red water. This study attempted to understand the effects of pipe materials on corrosion scale characteristics and water quality variations in WDS. A more than 20-year-old hybrid pipe section assembled of unlined cast iron pipe (UCIP) and galvanized iron pipe (GIP) was selected to investigate physico-chemical characteristics of corrosion scales and their effects on water quality variations...

Enhanced removal of As(V) and Se(VI) by zero valent iron (ZVI) has been recently revealed by using H2O2 as the corrosion accelerator, however, the detailed performance of such enhanced removal in ZVI column as well as the underlying mechanism is still unclear. In this study, the temporospatial evolution of As(V) and Se(VI) along a self-designed ZVI/H2O2 column in down-flow mode was systematically investigated. The variations of concerned aqueous parameters (pH, ORP, H2O2, Fe(2+), As, and Se) were monitored at different positions along the column throughout the experiments...

The reaction between Fe(2+) and H2O2 generates ·OH, which is capable of degrading organic pollutants. However, the weak conversion from Fe(3+) back to Fe(2+) limits its continuous reaction. Here, difference between Fenton system and modified Fenton system (i.e., Hydroquinone-Fenton, 1,4-Bezoquinone-Fenton, NH2OH-Fenton) for the regeneration of Fe(2+) was analyzed. UV-vis spectrometer and redox potential measurements were used to detect Fe(2+) concentration. HPLC was used to detect concentration of ·OH. Results indicated that, different from traditional Fenton system, Fe(2+) could be better regenerated in modified Fenton system...
