Abstract:
... A ferulic acid-sugar beet pulp pectin complex (FA-SBPP) was prepared using an immobilized enzyme (Novozym 435®) as the catalyst at 60 °C in a vacuum-controlled system. The structure of FA-SBPP was characterized by FT-IR and NMR (1H and 13C). In addition, the antioxidant activity of FA-SBPP was evaluated according to the DPPH free radical scavenging ability and ORAC values. Moreover, the physical a ...

Abstract:
... MCPA (4-chloro-2-methylphenoxyacetic acid) is an acidic herbicide, widely used in paddy fields. The presence of dissolved organic matter (DOM) modifies the sorption-desorption of herbicides in soils. In this study, effects of DOM on sorption- desorption of MCPA were tested using three typical ferralsol soil types from China: rhodic ferralsol, haplic ferralsol and paddy soil. DOM preparations were ...

Abstract:
... Identifying interactions between known drugs and targets is a major challenge in drug repositioning. In silico prediction of drug–target interaction (DTI) can speed up the expensive and time-consuming experimental work by providing the most potent DTIs. In silico prediction of DTI can also provide insights about the potential drug–drug interaction and promote the exploration of drug side effects. ...

Abstract:
... Blood serum and plasma are the most frequently used biofluids in metabolomics. The primary aim of this study was to ascertain the feasibility of the commonly used gas chromatography-mass spectrometry (GC-MS)-based methoximation followed by silylation with the BSTFA + 1% TMCS (MeOx-TMS) derivatization method, and to reveal the metabolic differences between serum and plasma. Individual variations we ...

Abstract:
... Automatic feature extraction from large-scale datasets is one of the major challenges when analyzing complex samples with gas chromatography-mass spectrometry (GC-MS). The classic processing pipeline basically consists of noise filtering, baseline correction, peak detection, alignment, normalization and identification. The long pipeline makes the extracted features inconsistent with different meth ...

Abstract:
... The voltammograms of lead and tin are strongly overlapped due to their similar properties in electroanalysis, making it difficult for the individual quantification of each analyte. A square wave anodic stripping voltammetry (SWASV) method for the simultaneous determination of the two metals at the bismuth film electrode (BiFE) was proposed. The experimental conditions were investigated and optimiz ...
