Enhanced dechlorination of an enzyme-catalyzed electrolysis system by ionic liquids: Electron transfer, enzyme activity and dichloromethane diffusion.

Enzyme-catalyzed electrolysis system (EES) is a promising technique for the efficient dechlorination of pollutants. In this study, ionic liquids (ILs) was first introduced to enhance the dichloromethane dechlorination performance of an EES. An imidazole-based IL, 1-ethyl-3-methylimidazole tetrafluoroborate ([EMIM][BF]), was chosen due to its excellent performance on dechlorination enhancement than other three ILs.

Effects of genetic variation and environmental factors on bergenin in Rodgersia sambucifolia Hemsl.

Ethnopharmacological Relevance: Bergenin is a well-known active compound that exhibits antioxidant, antiarrhythmic, hepatoprotective, and anti-inflammatory activities. However, the resource reserve of Rodgersia sambucifolia, one of the main raw materials for extracting bergenin, have sharply declined, and the bergenin content in different germplasms differs vastly, resulting in a serious shortage of the market supply of bergenin.

Aim Of The Study: To investigate the influence of genetic diversity and environmental factors on bergenin content in Rodgersia sambucifolia.

TZAP plays an inhibitory role in the self-renewal of porcine mesenchymal stromal cells and is implicated the regulation of premature senescence via the p53 pathway.

Background: Mesenchymal stromal cells (MSCs) were originally characterized by the ability to differentiate into different mesenchymal lineages in vitro, and their immunomodulatory and trophic functions have recently aroused significant interest in the application of MSCs in cell-based regenerative medicine. However, a major problem in clinical practice is the replicative senescence of MSCs, which limits the cell proliferation potential of MSCs after large-scale expansion. Telomeric zinc finger-associated protein (TZAP), a novel specific telomere-binding protein, was recently found to stimulate telomere trimming and prevent excessive telomere elongation.

Ethyl acetate fraction in ethanol extract from root of.

Objective: To evaluate the anti-tumor activity of ethyl acetate fraction (EFA), extracted with ethanol from the root of ""Dai-Bai-Jie"" in A549 cancer cells and its underlying mechanism.

Methods: ""Dai-Bai-Jie"" was extracted with 95% ethanol-aqueous (DBJ-1), 50% ethanol-aqueous (DBJ-2), and water (DBJ-3) by reflux method. 95% ethanol-aqueous extract was separated byethyl acetate (EFA) and n-butyl alcohol (DBJ-5), consecutively.

The effects of genetic variation and environmental factors on rhynchophylline and isorhynchophylline in Uncaria macrophylla Wall. from different populations in China.

Uncaria macrophylla Wall. is an important Chinese medicinal herb. Rhynchophylline (RIN) and isorhynchophylline (IRN) are its major active compounds.

miR-155 accelerates proliferation of mouse hepatocytes during liver regeneration by directly targeting SOCS1.

Liver regeneration after two-thirds partial hepatectomy (PH) is a clinically significant repair process for restoring proper liver architecture. Although microRNA-155 (miR-155) has been found to serve as a crucial microRNA regulator that controls liver cell function and proliferation, little is known about its specific role in the regenerating liver. Using a mouse model with miR-155 overexpression or miR-155 knockout, we investigated the molecular mechanisms of miR-155 in liver regeneration.

[Investigation, collation and research of traditional Dai medicine of China].

In order to find out the composition, characteristics and traditional utilization characteristics of Dai medicine and promote the rational protection, inheritance and utilization of the resources and traditional knowledge of Dai medicine in China, the resources of traditional Dai medicine have been investigated systematically and the traditional knowledge of Dai medicine have been analyzed in the article. We found out that there were altogether 1 077 kinds of traditional Dai medicine in China and among which 272 were the first time recorded in the condition of Dai folk medical uses. There were 1 053 plant medicines which belong to 169 family and 694 genus.

Transcriptome Analysis of Taxillusi chinensis (DC.) Danser Seeds in Response to Water Loss.

Background: Taxillus chinensis (DC.) Danser, the official species of parasitic loranthus that grows by parasitizing other plants, is used in various traditional Chinese medicine prescriptions. ABA-dependent and ABA-independent pathways are two major pathways in response to drought stress for plants and some genes have been reported to play a key role during the dehydration including dehydration-responsive protein RD22, late embryogenesis abundant (LEA) proteins, and various transcription factors (TFs) like MYB and WRKY.
