Sensomics-assisted analysis unravels the formation of the Fungus Aroma of Fu Brick Tea.

Fu Brick Tea (FBT) is characterized by Fungus Aroma (FA), which determines the quality of FBT products. However, the aroma constituents and their interactive mechanism for FA remain unclear. In this study, the FBT sample with the optimal FA characteristics was selected from 29 FBTs.

The impact of identity conflicts among Chinese knowledge-based miners on unsafe behavior: A moderated chain mediation model.

Background: In the context of smart mine construction, coal mine safety management is imposing stringent requirements on the safety competence of miners. To meet these demands, coal mine enterprises have initiated proactive measures to recruit a new generation of knowledge-based miners who possess high qualifications and specialized backgrounds.

Objective: This study aims to explore the underlying mechanisms of identity conflict (IC) and its influence on unsafe behavior (USB) among KBMs within the context of China's smart mining initiatives, as well as to identify the role of potential mediating and moderating variables in this relationship.

Effects of different aging methods on the ability of biochar to adsorb heavy metal cadmium and its physical and chemical properties.

The aging process can affect the physical and chemical properties as well as adsorption capacity of biochar. This study focuses on the heavy metal cadmium (Cd) as the research object, and artificially ages biochar prepared from rice straw and corn straw through accelerated freeze-thaw cycles, alternating dry wet cycles, and ultraviolet light treatment, in order to evaluate the effects of different aging conditions on the physical and chemical properties of the two different types of biochar and on their adsorption capacities for Cd. After aging, the pH of rice and corn biochar decreased to varying degrees, respectively.

Widely targeted volatileomics analysis reveals the typical aroma formation of Xinyang black tea during fermentation.

Xinyang black tea (XYBT) is characterized by the honey sugar-like aroma which is produced during the fermentation process. However, the formation of this typical aroma is still unclear. We here performed widely targeted volatileomics analysis combined with GC-MS and detected 116 aroma active compounds (AACs) with OAV > 1.

Effects of microplastics and cadmium on the soil-wheat system as single and combined contaminants.

Two types of microplastics (MPs) (micro polyethylene (mPE) and micro polypropylene (mPP)) were studied alongside and cadmium (Cd) to determine how they affected soil-wheat systems, both individually and in mixed combinations. This was accomplished by carrying out a pot experiment to reveal their respective interaction effects. Results showed that in different Cd pollution levels soils (0, 1, and 5 mg kg), chlorophyll concentrations in wheat leaves decreased markedly with rising levels of mPE/mPP.

Effect of Microplastics on the Adsorption and Desorption Properties of Cadmium in Soil.

This study analyzed the role of micro polyethylene (mPE) and micro polypropylene (mPP) on cadmium (Cd) adsorption and desorption in soil. Cd adsorption in soils reached equilibrium within 240 min with or without mPP/mPE. The largest Cd adsorption amount was 923.

Role of particle aggregates in herbal medicine decoction showing they are not useless: considering Coptis chinensis decoction as an example.

A large number of plants and fungi are homologs of medicine and food, and are used in the form of decoctions for complementary foods, dietary cures, and disease therapy in traditional medicine. Besides the widespread concern around the physiological and pharmacological actions of the active ingredients, the phase change in decoction and its influences on the active ingredients' absorption should not be ignored. Lots of particle aggregates are generated during the decoction of herbal medicine and then end up being taken together with the active ingredients.

In situ eNOS/NO up-regulation-a simple and effective therapeutic strategy for diabetic skin ulcer.

Decreased nitric oxide (NO) synthesis and increased NO consumption in diabetes induces the inadequate blood flow to tissues that is primarily responsible for the pathogenesis and refractoriness of diabetic skin ulcers. The present study proposed a simple and effective therapeutic strategy for diabetic skin ulcers-in situ up-regulation of endothelial nitric oxide synthase (eNOS) expression and NO synthesis by statin-loaded tissue engineering scaffold (TES). In vitro experiments on human umbilical vein endothelial cells indicated that the statin-loaded TES relieved the high-glucose induced decrease in cell viability and promoted NO synthesis under high-glucose conditions.
