Abstract:
... Biomass has attracted considerable attention from both researchers and practitioners as an important renewable energy source that can help achieve sustainable development. However, inefficient biomass logistics systems hinder the development of biomass utilisation. This study investigates a two-echelon biomass resource location-routing problem (2E-BRLRP). Considering a predetermined supply of biom ...

Abstract:
... A series of water-soluble co-polymer (NS) from N-vinylpyrrolidone (NVP) and sodium p-styrenesulfonate (SSS) with a low molecular weight are synthesized as substitutes for urea in the reactive printing of cotton fabrics. The effects of the monomer ratio of NVP to SSS on the color yield of the printed fabrics, the color fastness, and the solubility of the reactive dyes were investigated. The possibi ...

Abstract:
... Taraxacum mongolicum Hand.-Mazz. has been used in lung cancer treatment in Chinese medicine. However, its specific mechanism of action has not yet been reported, and developing pharmaceutical anti-cancer resources is important. Here, we aimed to elucidate the anti-tumor effects of dandelion in vitro and in vivo and assess its effects on immune function in lung cancer patients.In the present study, ...
... Obesity continues to be a global public health challenge. Litchi chinensis seed is rich in bioactive ingredients with pharmacological effects, such as hypoglycemic activity and anti-oxidation. This study aimed to assess the potential anti-obesity effects of L. chinensis seed and the changes of gut microbiota and mycobiota compositions in obese zebrafish induced by a high-fat diet. The anti-obesity ...
... Fluorine (F) is widely dispersed in the environment and frequently used in industry and agriculture with a high migration ability. Thus, it is essential to understand the leaching characteristic of F in soil from industry and agriculture sources. Several sources of F pollutants in soil, including fertilizers, pesticides, phosphogypsum, and atmospheric deposition, were selected to investigate leach ...
... Golden Syrian hamster (GSH) have many advantages as animal models in preclinical research, but their application is currently limited by the lack of standardized techniques for analyzing gene expression. Quantitative real-time polymerase chain reaction (RT-qPCR) is a sensitive method for analyzing gene expression, but its reliability depends upon the selection of stable reference (“housekeeping”) ...

Abstract:
... A chemical investigation on the aerial parts of Euphorbia neriifolia led to the identification of thirteen undescribed diterpenoids, phorneroids A–M, including ent-abietane (A–D), ent-kaurane (E–G), ent-atisane (H–K), and ent-isopimarane (L and M) types, together with three known compounds. Phorneroid A represents the first example of 8-spiro-fused 9,10-seco-ent-abietane diterpenoid lactone featur ...
... Biochar additions to soil have been proposed as an environment-friendly way to enhance the soil nutrients or to amend the contaminated soils; however, few studies have evaluated the effectiveness of biochars from an integrated perspective of soil remediation and quality improvement, especially for the soil contaminated by vanadium with increasing prevalence, complex species and chemistry, widespre ...
... RNA binding motif proteins (RBMs) have been widely implicated in the tumorigenesis of multiple human cancers but scarcely studied in nasopharyngeal carcinoma (NPC). Here, we compare the mRNA levels of 29 RBMs between 87 NPC and 10 control samples. We find that RBM47 is frequently upregulated in NPC specimens, and its high expression is associated with the poor prognosis of patients with NPC. Biolo ...
... The Clt-1 protein may interact with other functional proteins via a BTB (Drosophila transcription factors Bric-a-brac, Tramtrack and Broad Complex) domain to regulate methyl 5-(hydroxymethyl) furan-2-carboxylate toxin production in the fungal pathogen Curvularia lunata. To date, however, the proteins that interact with Clt-1 are unknown. In this study, a high-quality yeast two-hybrid (Y2H) library ...
... In our previous study, we have successfully cloned and deleted the pks18 gene, which is involved in 1,8‐dihydroxynaphthalene melanin and methyl 5‐(hydroxymethyl) furan‐2‐carboxylate toxin production and in the pathogenicity of Curvularia lunata. Moreover, we hypothesized that other genes may also be related to the melanin and toxin production, or pathogenicity. In this study, a transcriptome appro ...

Abstract:
... A heterogeneous photocatalyst based on copper modified phosphorus doped g-C₃N₄ (Cu/P-CN) has been prepared and characterized. This recyclable catalyst exhibited high photocatalytic activity for the synthesis of N-arylpyridin-2-amine derivatives by the reaction of 2-aminopyridine and aryl boronic acid at room temperature under the irradiation of blue light. Importantly, the range of substrates for ...
... The vibration problem associated with rice transplanters not only affects the quality and effect of the transplanting operation but also reduces the service life of the machine. With a focus on the vibration problem in the working process of a high-speed rice transplanter, a mechanical deformation prediction system based on the effective independence method for modal analysis was developed. This s ...
... Stabilization technique is regarded effective to control heavy metal pollution in soil. Traditional stabilizers have raised concerns about soil acidification/alkalization, or the stable effectiveness in a long-term. To stabilize vanadium (V) in calcareous purple soil in an environmentally friendly way, Na-bentonite (Na–B) modified by tea polyphenol (TP-B), by FeSO₄ (Fe–B), and by TP and FeSO₄ (TP- ...
... Fifteen new labdane-type diterpenoids, sublyratins A–O (1–15), along with four known analogues (16–19) were isolated from the aerial parts of Croton sublyratus. Their structural assignments were challenging due to the stereoisomeric features evident and were achieved by analyzing comprehensively the spectroscopic data and electronic circular dichroism spectra and using X-ray crystallographic analy ...

ENP701 fermentation broth, a microorganism from the east China sea, one new quinolactacin was isolated and named quinolactacin-H. The structure of quinolactacin-H was determined by spectroscopic analysis and the absolute configurations by X-ray crystallographic ...
... An asymmetric bi-functional gel polymer electrolyte (GPE) with an interpenetrating network (IPN) has been prepared by in situ cationic polymerization of 1,3-dioxolane (DOL) (PDXL) and cross-linking of cyanoethyl polyvinyl alcohol (PVA-CN), which is initiated by lithium hexafluorophosphate. The mechanism of the Ritter reaction was proposed for the cross-linking of PVA-CN. The IPN-GPE has a high ion ...
... Panax japonicus is the dried rhizome of Panax japonicus C.A. Mey. (Araliaceae). Saponins from Panax japonicus (SPJ) exhibit anti-inflammatory and antioxidative effects. To explore the neuroprotective effect of SPJ on natural ageing of rat. Sprague-Dawley (SD) rats 18-month-old were divided into ageing control, ageing treated with SPJ 10 or 30 mg/kg (n = 8). Five-month-old rats were taken as the ad ...
