Abstract:
... With rapid urbanization, the interactions between human and land are becoming more and more intense, which leads to increasingly diversified land use and intensifies the conflicts among land use functions (LUFs). However, land use multi-functionality (LUMF) of densely populated areas (DPAs) in less developed regions has not been studied in depth. The objective of our study is to build a multi-func ...

Abstract:
... The Belt and Road Initiative (BRI) has revealed that it is necessary to strengthen research on land use and land cover change (LUCC) and ecological risk in key regions of countries around the world. In this study, the spatiotemporal characteristics of LUCC in the five capitals of Central Asian countries within the BRI were analyzed. Based on the grid scale, a landscape pattern index was introduced ...
... Limonoids, a kind of natural tetranortriterpenoids with diverse skeletons and valuable insecticidal and medicinal bioactivities, are the characteristic metabolites of most plants of the Meliaceae family. The chemistry and bioactivities of meliaceous limonoids are a continuing hot area of natural products research; to date, about 2700 meliaceous limonoids have been identified. In particular, more t ...
... DGT (diffusive gradients in thin films) technique has been developed for measuring nitrogen in freshwaters and applied to assess the bioavailability of phosphorus in soils/sediments. These two elements are the main nutrients causing algae bloom, but DGT has never been used in the field water conditions with algae bloom. In our study, a pair of DGT devices were used in comparison with grab sampling ...
... Visible light-assisted catalysis has recently attracted considerable attention because it is efficient, cost effective, and does not cause indoor air pollution. Several birnessite-type MnO₂ catalysts with different numbers of manganese vacancies (MVs) were synthesized in this study and used for photo-assisted catalytic oxidation of HCHO. Under visible light irradiation, MVs act as trapping centers ...

Abstract:
... Accelerating the interfacial charge transfer process (ICTS) of the catalysts can immensely improve the photocatalytic efficiency. Doping transition metal ions not only promote the ICTS, but also boost multielectron reduction reactions of oxygen. Herein, birnessite-type MnO₂ have been modified by different transition metal ions (TM = Zn²⁺, Cu²⁺, and Fe³⁺) in this work. Post-doping, Fe-Birnessite wa ...
... Plant flavonoids, such as quercetin (QE), are traditionally used to treat liver injuries. Given the limited bioavailability of quercetin, sodium quercetin-5′-sulfonates (QS) were synthesised and characterised. Although beneficial effects of QE on the fatty liver are observed in vertebrates, the exact mechanism is still unclear, particularly in fish livers. As a result, RNA-sequencing was conducted ...
... Peel colour is a very important appearance quality and is strongly associated with commercial value. Green, russet and partially russet peels are observed in the fruit of Pyrus pyrifolia. Currently, the mechanisms of peel russeting in fruit development are still uncertain. Two pear cultivars, ‘Zaoshengxinshui’ (russet peel) and ‘Qiushui’ (green peel), and 92 offspring were sequenced by specific-lo ...

Abstract:
... Using Si-based photoelectrodes to generate H₂ through photoelectrochemical (PEC) water splitting has attracted extensive attention in recent years. To produce H₂ with a high efficiency, the key issues that need to be solved are the relatively low photovoltage of the Si-based photoelectrode and the sluggish kinetics of the H₂ generation reaction occurring on the surface of Si. In this study, we des ...

Abstract:
... Water is featured in an indispensable role during the process of catalytic oxidation of HCHO. In this work, a rich water-containing birnessite-type MnO₂ was synthesized, and its water content was adjusted through calcination. Phase structure and texture properties of the prepared birnessite were characterized. It was revealed that three types of water (namely absorbed water, molecular water, and s ...

Abstract:
... Slowing down DNA translocation speeds through solid-state nanopores is of vital importance to detect temporal and electrical signals with single-base resolution. To control DNA translocation speed and maintain sequencing sensitivity, the graphene nanoslit sensor is proposed and molecular dynamics simulations are performed to investigate geometric and electrophoretic effects. Results show that the ...
... Sarcandra glabra (Thunb.) Makino (Chloranthaceae) is abundant and shows important clinical effects. Traditionally, S.glabra is used to treat diseases involving inflammation, such as bone fracture and joint swelling. Lindenane-type sesquiterpenoids and dimers are the major anti-inflammatory components in S. glabra. Trishizukaol A (TSA), is an abundant lindenane sesquiterpenoid trimer in S.glabra, b ...
... αS₁-Casein (encoded by the CSN1S1 gene) is associated with food allergy more than other milk protein components. Milk allergy caused by αS₁-casein is derived from cow milk, goat milk and other ruminant milk. However, little is known about the transcription regulation of αS₁-casein synthesis in dairy goats. This study aimed to investigate the regulatory roles of signal transducer and activator of t ...
... Methylene blue (MB) is extensively used in the textile industry; meanwhile, it is also one of carcinogenic and mutagenic pollutants. The removal of MB from wastewater by photocatalytic decomposition under visible light irradiation is a very important method. In this work, a photocatalyst of Mo-doped TiO₂ coated on fly ash cenosphere (CTAB-Mo-TiO₂/FAC) was prepared by a sol-gel method and modified ...
... Classical swine fever (CSF) is caused by classical swine fever virus (CSFV) and has led to huge economic losses in the pig industry worldwide. Although vaccination and other control measures have been carried out, it is essential to establish a rapid and valid method for CSF vaccination monitoring and clinical diagnosis. The CSFV E2 protein has been widely used as a major antigen for antibody dete ...

Abstract:
... Limonoids are considered the effective part in Meliaceae plants that exert anti-inflammatory effects. Gedunin-type limonoids specifically have anti-inflammatory effects. However, the role of gedunin-type limonoids in the inflammatory diseases mediated by NLRP3 inflammasome remains to be explored. We found that deacetylgudunin (DAG), a gedunin-type limonoid from Toona sinensis, had similar anti-inf ...
... The current study was conducted to investigate the influences of ferulic acid (FA) as a dietary addition on growth performance, serum biochemical indices, liver morphology, antioxidant capacity, non-specific immunity, and expression of genes related to growth, immunity, apoptosis, and antioxidation in juvenile hybrid grouper (Epinephelus fuscoguttatus♀ × Epinephelus polyphekadion♂). Seven experime ...
... Sarglanoids A–F, six new sesquiterpenoids belonging to eudesmane (1–5) and eremophilane (6) types, were isolated from the leaves of Sarcandra glabra, a famous traditional Chinese medicine (TCM). Their structures including absolute configurations were elucidated through extensive spectroscopic analysis and electronic circular dichroism (ECD) calculations. Compounds 1–2 were rare N-containing eudesm ...
... In nonruminants, microRNA (miRNA)-24 plays an important role in lipid metabolism in adipose tissue and the liver. Although the abundance of miR-24 in ruminant mammary glands is the highest during peak lactation, its potential role in regulating the synthesis and secretion of fat into milk is unclear. This study aimed to identify the function of miR-24 in these processes using CRISPR/Cas9 technolog ...
... Osteoarthritis (OA) is a common disease caused by damage to articular cartilage and underlying bone tissues. Early OA can be treated by intra-articular injection of viscosupplements to restore the lost viscoelasticity and lubricity of synovial fluid. Hyaluronic acid (HA), as a most standard synovial fluid supplementation, can be easily degraded in vivo, bringing about lower viscoelasticity and inc ...
