Abstract:
... To achieve secure and efficient saline water irrigation in arid areas, a field experiment was conducted to evaluate the salt distribution in the soil profile and response of sunflower (Helianthus annuus L.) to salinity from 2018 to 2020. The experiment included five levels of irrigation water salinity (ECi = 0.5 dS/m, 3.3 dS/m, 4.9 dS/m, 6.6 dS/m and 8.2 dS/m). The results indicated that the soil ...
... Takyric solonetz is a highly saline‐sodic soil with poor soil structure and a saturated hydraulic conductivity close to zero. Drip irrigation, soil‐water‐redistribution medium (RM), ridge planting and film mulching have been successfully used to ameliorate such soils. Here, we compared soil moisture and cation distribution during the amelioration with planting years of 1, 3, 4, 5 and 6. A suitable ...

The experiment carried out in 2019 and 2020, included four drip irrigation treatments, designated 0 (control, no irrigatio ...
... Dactylicapnos torulosa (D. torulosa) has been traditionally used as a therapeutic remedy. Here, a combined strategy using both phytochemical and biological approaches was conducted to discern the effective components of D. torulosa. Three new alkaloids, namely, (1–3), Torulosine A, 1-Methoxypseudoprotopine and 1,14-Dimethoxyprechilenine together with 33 (4–36) known compounds were isolated. The st ...
... The electrical conductivity of saturated paste extracts (ECₑ) is more widely used as the laboratory method for estimating soil salinity compared to the soil-water ratio method. However, the current saturated paste process is time consuming and mainly based on subjective experience, and the quantitative relationships among the factors influencing the saturated paste process are not clear. In order ...
... Fine activated alumina (FAA) acting as an adsorbent for phosphate was synthesized from an industrial sodium aluminate solution based on phase evolution from Al(OH)₃ and NH₄Al(OH)₂CO₃. This material was obtained in the form of γ-Al₂O₃ with an open mesoporous structure and a specific surface area of 648.02 m² g⁻¹. The phosphate adsorption capacity of the FAA gradually increased with increases in pho ...

Abstract:
... Hostaflavone A (HA) is a new flavonoid component isolated from the flower of Hosta plantaginea (Lam.) Asch., which is commonly used as a folk herbal to treat inflammatory diseases in China. Nevertheless, the anti-inflammatory effect of HA remains unknown.This work aimed to evaluate the HA with anti-inflammatory activity and mechanism in RAW 264.7 macrophages activated by lipopolysaccharide (LPS).A ...
... The conversion of Al-substituted goethite (Al-goethite) to hematite in gibbsitic bauxite is conducive to alumina extraction during the Bayer process and the enrichment of iron minerals in red mud. In this work, mineralogical characteristics of gibbsitic bauxite were identified by AMICS analysis, and the low-temperature thermal conversion behavior of both synthetic Al-goethite and natural Al-goethi ...
... Rich foam is often formed in Bayer liquors, providing a promising short green process for the removal of organics by foam flotation. In this study, foam flotation of sodium oxalate (SO), sodium benzoate (SB), sodium citrate (SC), and sodium stearate (SS) was investigated using sodium dodecyl sulfate (SDS) as a frother and collector in a synthetic sodium aluminate solution. The feasibility of foam ...
... Citrus Huanglongbing (HLB) has posed a great challenge to the citrus production. Timely removal of HLB infected trees was considered as one of the most effective strategies for citrus orchard management. Therefore, rapid detection of HLB disease is urgently needed. The study was aimed to propose an effective method for HLB disease detection by developing a handheld device to capture multicolor flu ...
... Sparse vegetation and soil desertification are widespread phenomena in coastal regions due to the accumulation of excess sodium in soil, which results in degraded land quality and ecological impairment. Artificial reclamation approaches, including physical, chemical, hydro-technical, and phytoremediation techniques, have failed mainly due to freshwater shortages, high costs, and a relative lack of ...

Abstract:
... Gut microbiome (GM) is closely related to the overall health status for the human being. The dysfunction of microbiome can lead to many diseases such as inflammation, cancer and neurodegenerative disease. Therefore, it's of great importance to develop effective strategy to regulate GM. Gut lumen-targeted oral delivery system (GLT-ODS) has been extensively investigated and widely used in food scien ...
... The noble gases He and Ar are trace components in natural gas. Although their genesis is significantly different from that of hydrocarbon gases, they can provide key information on the accumulation and preservation of natural gas. In this paper, the relative and absolute abundances of He and Ar in lower Paleozoic shale gas samples from different areas of southern China were systematically analyzed ...

Abstract:
... Citrus Huanglongbing (HLB) is nowadays one of the most fatal citrus diseases worldwide. Once the citrus tree is infected by the HLB disease, the biochemistry of the phloem region in midribs would change. In order to investigate the carbohydrate changes in phloem region of citrus midrib, the semi-quantification models were established to predict the carbohydrate concentration in it based on Fourier ...
... Phospholipids (PLs) are important components of physiological metabolism in animals and plants, and they have been widely used in clinical treatment, cosmetics, and industry. With the development of marine resources, marine PLs rich in polyunsaturated fatty acids have attracted increasing attention. As important marine resources, shrimp heads (SH), codfish roe (CR), and squid gonads (SG) contain a ...

Abstract:
... Saline water irrigation can alleviate the deficiency of agricultural freshwater resources, especially in arid regions. However, saline water may lead to soil salinization and affect crop quality. A water-salt regulation (WSR) irrigation method has been developed to avoid soil salinization. To investigate the effect of saline water irrigation on crop quality while maintaining soil salinity balance, ...
