In order to explore the evolution process of regional vegetable circulation efficiency and its influencing factors, this paper uses Super-SBM model considering unexpected output and GML index to calculate the vegetable circulation efficiency of 13 provinces (cities) in Central China and its surrounding areas from 2015 to 2019, then conducts spatial autocorrelation analysis on the vegetable circulation efficiency in this region through Moran index. Finally, SPDM model is constructed to explore the spatial effect of the influencing factors on the vegetable circulation efficiency in this region. The results show that (1) the vegetable circulation efficiency of most provinces (cities) in this region is low. (2) The Global Moran's I of the vegetable circulation efficiency in this region is positive, that is, the vegetable circulation efficiency in this region shows a certain degree of spatial agglomeration effect. (3) The level of scientific and technological innovation and the degree of government support have significant positive direct and indirect effects on the efficiency of vegetable circulation in the region, the quality of workers has significant positive indirect effects, and the level of economic development and industrial structure have significant negative indirect effects.

Background: Triglyceride glucose (TyG) index has been proposed as a credible and simple surrogate indicator for insulin resistance. The primary aim of this study was to novelly examine the associations between dietary patterns reflecting variations in circulating TyG index and the risk of type 2 diabetes mellitus (T2DM).

Methods: This study included 120,988 participants from the UK Biobank, all of whom completed multiple 24-h dietary assessments.

Cystic and alveolar echinococcosis are severe zoonotic diseases characterized by long asymptomatic periods lasting months or years. Viable Echinococcus spp. eggs released into the environment through the feces of canids can infect humans through accidental ingestion via hand-to-mouth contact or consumption of contaminated food or water.

Nobiletin (NOB), a lipid-soluble polymethoxyflavone with potent antioxidant, antimicrobial, and anti-inflammatory properties, suffers from poor stability and pH sensitivity, limiting its bioavailability. In this study, Pickering high internal phase emulsions (HIPEs) stabilized by soy protein isolate (SPI) and κ-carrageenan (KC) were developed to encapsulate and protect NOB. The emulsions, containing a 75 % medium-chain triglyceride (MCT) volume fraction, were optimized by investigating the effects of pH and KC concentration on the key properties such as the creaming index, particle size, zeta potential, microstructure, and rheology.
