Abstract

Background: Curcumin (Cur) is a natural pigment containing a diketone structure, which has attracted extensive attention due to its strong functional activities. However, the low solubility and poor stability of Cur limit its low bioavailability and multi-function. It is essential to develop effective measures to improve the unfavorable nature of Cur and maximize its potential benefits in nutritional intervention. Scope and approach: The focus of this review is to emphasize the construction of lipo-solubility delivery vehicles for Cur, including emulsion, nanoliposome and solid liposome. In addition, the potential benefits of vehicles-encapsulated Cur in the field of precise nutrition were summarized, including high targeting properties and multiple disease interventions. Further, the deficiencies and prospects of Cur encapsulated in vehicles for precise nutrition were discussed. Key findings and conclusions: The well-designed lipo-solubility delivery vehicles for Cur can improve its stability in food processing and the digestion in vivo. To meet the nutritional requirements of special people for Cur-based products, the improvement of the bioavailability by using delivery vehicles will provide a theoretical basis for the precise nutrition of Cur in functional food. HIGHLIGHTS: Structural properties and bioavailability of curcumin were summarized. The practical problems and challenges in the utilization of curcumin were discussed. Various technologies for preparing lipo-solubility delivery vehicles for curcumin were described. The design of delivery vehicles for curcumin and intervention strategies in precise nutrition was reviewed. [ABSTRACT FROM AUTHOR]

Abstract

Cutting performance and wear mechanism of spark plasma-sintered Si3N4 (SN91) and Si3N4/WC (SW10) ceramic tools in the dry turning of 41Cr4 hardened steel are studied. SN91 tool shows better wear resistance than SW10 tool and commercial ceramic tool SW500 and cemented carbide tool YG8 under the same cutting conditions. The better cutting performance of SN91 can be attributed to its excellent high-temperature flexural strength. The most significant factor affecting the tool life of SN91 is the cutting speed. A higher material removal volume can be achieved at a low cutting speed, large depth of cut, and large feed rate. A long cutting distance/time can be achieved at a low cutting speed, small depth of cut, and feed rate. At a cutting speed of 103.62 m/min (ap = 0.1 mm, and f = 0.05 mm/rev), the wear mechanisms of SN91 are adhesion, oxidation, and diffusion, and no crater wear is observed on the rake face. At a cutting speed of 214.31 (ap = 0.3 mm and f = 0.05 mm/rev) and 314 m/min (ap = 0.2 mm and f = 0.05 mm/rev), the failure forms of SN91 tool are mainly rake face crater wear and flank wear; the wear mechanisms of rake face are diffusion, abrasion, and oxidation; and the wear mechanisms of flank face are abrasion, adhesion, and oxidation. The failure forms of SW10 tool are mainly rake face crater wear and flank wear, and the wear mechanisms are diffusion, abrasion, adhesion, and oxidation.

Abstract

African swine fever (ASF) is one of the most severe infectious diseases of pigs. In this study, a loop‐mediated isothermal amplification (LAMP) assay coupled with the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a system was established in one tube for the detection of the African swine fever virus (ASFV) p72 gene. The single‐stranded DNA–fluorophore quencher reporter and CRISPR‐derived RNA were screened and selected for the CRISPR detection system. In combination with LAMP amplification assay, the detection limit for the LAMP–CRISPR assay can reach 7 copies/μl of p72 gene per reaction. Furthermore, this method displays no cross‐reactivity with other porcine DNA or RNA viruses. The performance of the LAMP–CRISPR assay was compared with real‐time qPCR tests for clinical samples; a good consistency between the LAMP–CRISPR assay and real‐time qPCR was observed. The method shed a light on the convenient, portable, low cost, highly sensitive and specific detection of ASFV, demonstrating a great application potential for monitoring on‐site ASFV in the field.
