Comparison between ATR-IR, Raman, concatenated ATR-IR and Raman spectroscopy for the determination of total antioxidant capacity and total phenolic content of Chinese rice wine.

Food Chem. 194 , 671-9, (2015)

The application of attenuated total reflectance infrared spectroscopy (ATR-IR), Raman spectroscopy (RS) and combination of ATR-IR and RS for measurements of total antioxidant capacity (TAC) and total phenolic content (TPC) of Chinese rice wine (CRW) were inve...

Arhodomonas sp. strain Seminole and its genetic potential to degrade aromatic compounds under high-salinity conditions.

Appl. Environ. Microbiol. 80(21) , 6664-76, (2014)

Arhodomonas sp. strain Seminole was isolated from a crude oil-impacted brine soil and shown to degrade benzene, toluene, phenol, 4-hydroxybenzoic acid (4-HBA), protocatechuic acid (PCA), and phenylacetic acid (PAA) as the sole sources of carbon at high salini...

Antagonistic control of a dual-input mammalian gene switch by food additives.

Nucleic Acids Res. 42(14) , e116, (2014)

Synthetic biology has significantly advanced the design of mammalian trigger-inducible transgene-control devices that are able to programme complex cellular behaviour. Fruit-based benzoate derivatives licensed as food additives, such as flavours (e.g. vanilla...

DNA-Linked Enzyme-Coupled Assay for Probing Glucosyltransferase Specificity.

ACS Synth. Biol. 4 , 833-41, (2015)

Traditional enzyme characterization methods are low-throughput and therefore limit engineering efforts in synthetic biology and biotechnology. Here, we propose a DNA-linked enzyme-coupled assay (DLEnCA) to monitor enzyme reactions in a high-throughput manner....

Age-related reference values for urinary organic acids in a healthy Turkish pediatric population.

Clin. Chem. 40(6) , 862-6, (1994)

Organic acid concentrations were quantified by gas chromatography and the individual acids identified by mass spectrometry in urine specimens from a healthy Turkish pediatric population of ages 2 days to 16 years, subdivided into five age groups. We quantifie...

Convenient QSAR model for predicting the complexation of structurally diverse compounds with β-cyclodextrins

Bioorg. Med. Chem. 17 , 896-904, (2009)

This paper reports a QSAR study for predicting the complexation of a large and heterogeneous variety of substances (233 organic compounds) with beta-cyclodextrins (beta-CDs). Several different theoretical molecular descriptors, calculated solely from the mole...

Calculating virtual log P in the alkane/water system (log P(N)(alk)) and its derived parameters deltalog P(N)(oct-alk) and log D(pH)(alk).

J. Med. Chem. 48 , 3269-79, (2005)

Growing interest in the use of both the logarithm of the partition coefficient of the neutral species in the alkane/water system (log P(N)(alk)) and the difference between log P(N)(oct) (the logarithm of the partition coefficient of the neutral species in the...

Efficient removal of insecticide "imidacloprid" from water by electrochemical advanced oxidation processes.

Environ. Sci. Pollut. Res. Int. 21(14) , 8387-97, (2014)

The oxidative degradation of imidacloprid (ICP) has been carried out by electrochemical advanced oxidation processes (EAOPs), anodic oxidation, and electro-Fenton, in which hydroxyl radicals are generated electrocatalytically. Carbon-felt cathode and platinum...

Optimization of antioxidant phenolic compounds extraction from quinoa (Chenopodium quinoa) seeds.
