Subject-dependent Inversion in English: A Corpus-based Investigation
Yujiao Feng,Jong-Bok Kim(김종복) 한국언어학회 2021 언어 Vol.46 No.4
Subject-dependent inversion is one of the inverted constructions in which the complement of the copula be is preposed to the left of the main verb, whereas the grammatical subject is placed in the postverbal position. The inversion is constrained by the relative discourse familiarity of information represented by the preposed and postposed phrases. In addition, the principle of end-weight also plays a role in the felicity of inversion. This paper reviews some key properties of the predicate inversion in English and investigates their real-life uses with the corpus COCA (Contemporary Corpus of American English). Based on the attested data, the paper also sketches a theoretical direction that can account for its intriguing grammatical properties.

Recent reports have shown the antidiabetic effect of Moringa oleifera from various parts of the world. However, M. oleifera from Cambodia has never determined. Therefore, the aim of this study was to assess the antidiabetic effect of M. oleifera extract from Cambodia. The leaf ethanolic extract contained flavonoids (31.90 mg/mL), polyphenols (53.03 mg/mL), lycopene (0.042 mg/mL), and ß-carotene (0.170 mg/mL), and possessed 2,2-diphenyl-1-picrylhydrazyl, hydrogen peroxide, and hydroxyl radical scavenging activities of 92.40, 99.25, and 83.57 TE/μM at 1 mg/mL, respectively. Db/db mice were orally administered the leaf extract (150 mg/kg/day) for 5 weeks. M. oleifera treatment significantly ameliorated the altered fasting plasma glucose (from 483 to 312 mg/dL), triglyceride (from 42.12 to 23.00 mg/dL), and low-density lipoprotein cholesterol (from 107.21 to 64.25 mg/dL) compared to control group, and increased the insulin levels from 946 ± 92 to 1678 ± 268 pg/mL. The histopathological damage and expression levels of tumor necrosis factor-alpha, interleukin (IL)-1β, IL-6, cyclooxygenase-2, and inducible nitric oxide synthase in renal tissue decreased. These results indicate the potential antidiabetic benefits of M. oleifera ethanolic leaf extract.

Finding appropriate usage of waste printed circuit board (WPCB), a kind of electronic trash, is an importanttask from background of environment protection and waste management. Due to the intrinsic highhindrance barrier capability, recycled epoxy resin in rich source from WPCB gives opportunity for corrosionprotection of metals based on Two birds with one stone ideology. One stone in this ideology is to applywaste as resource, and two birds respectively indicate using PCB waste as valuable material and inhibitingmetal corrosion. In this paper, by combining biomimetics strategy, we adopt a three-step methodincluding anodic oxidation, hydrophobic treatment and infusion of composite containing epoxy resinfrom WPCB and dimethyl silicone oil to finally form WPCB based slippery liquid-infused porous surface(W-LIS). Morphology, composition, wettability and electrochemical properties are characterized bysophisticated techniques. Adding recycled hydrophobic/oleophilic epoxy resin from WPCB into oil phasecan effectively increase the barrier effect and raise anticorrosion ability. Moreover, W-LIS delivers antifreezingadhesion and biofouling inhibition property, which is obviously superior to LIS and lotus inspiredsuperhydrophobic (SHS) coating. The various excellent performances of W-LIS indicate epoxy resin fromwaste printed circuit board can act a versatile role in field of metal corrosion prevention.

Deer velvet antler (DVA) is one of the most popular medicines in China. Numerous studies have demonstrated that velvet antler possess biological effects. However, data regarding its anti-migration activity on prostate cancer is scarce. In this study, we investigated the inhibitory effect of top DVA (T-DVA) on the expression of prostate-specific antigen (PSA) and migration-related genes in the human prostate cancer cell, LNCaP. The T-DVA down-regulated the expression of PSA. In addition, the Radius TM assay revealed that T-DVA inhibited the migration behavior of prostate cancer cells. Furthermore, the expression of matrix metalloproteinase (MMP)-9 and vascular endothelial growth factor (VEGF) was also decreased with T-DVA. On the contrary, T-DVA increased the tissue inhibition of metalloproteinase (TIMP)-1 and (TIMP)-2. Taken together, our findings indicate that the T-DVA possesses anti-migration activity on prostate cancer cells. This is the first study of DVA to report the anti-migration activity on prostate cancer.

<P>We investigated the biologically active substances contained in RVA (regrowth velvet antler) by comparing the composition of biologically active substances and antioxidant potential of different antler segments. RVA was subjected to extraction using DW (distilled water). RVA was divided into 3 segments: T-RVA (top RVA), M-RVA (middle RVA), and B-RVA (base RVA). The T-RVA section possessed the greatest amounts of uronic acid (36.251 mg/g), sulfated GAGs (sulfated glycosaminoglycans) (555.76 mg/g), sialic acid (111.276 mg/g), uridine (0.957 mg/g), uracil (1.084 mg/g), and hypoxanthine (1.2631 mg/g). In addition, the T-RVA section possessed the strongest antioxidant capacity as determined by DPPH, H2O2(hydrogen peroxide), hydroxyl, and ABTS (2,2′-azinobis-3-ethylbenzthiazoline-6-sulphonate) radical scavenging activity as well as FRAP (ferric reducing antioxidant power) and ORAC (oxygen radical absorbance capacity). The values of those were 53.44, 23.09, 34.12, 60.31, and 35.81 TE/<I>μ</I>M at 1 mg/mL and 113.57 TE/<I>μ</I>M at 20 <I>μ</I>g/mL. These results indicate that the T-RVA section possesses the greatest amount of biologically active substances and highest antioxidant potential. This is the first report on the biologically active substances and antioxidant potential of RVA.</P>
