Depression is a complex and prevalent mental illness. Cherry leaf is a traditional Chinese herbal medicine, which has confirmed to exert a certain antidepressant effect, but its potential neural regulation mechanism is not clear. This paper aims to investigate the improved action of cherry leaf decoction (CLD) on chronic unpredictable mild stress (CUMS) rats and its potential neural regulation mechanism by verifying the role and function of NMDAR regulatory target α2δ-1 in depression due to CUMS. Male SD rats were subjected to random stressors persisting for 5 weeks to establish the CUMS depression rat model. CLD could effectively alleviate depression-like behaviors of CUMS rats in behavioral tests including sucrose preference test, forced swimming test, tail suspension test and open field test. After the administration of the CLD, the expression of corticotropic-releasing hormone (CRH) in the hypothalamus was inhibited. Moreover, the levels of CRH, adrenal cortical hormone (ACTH) and corticosterone (CORT) in serum also decreased significantly. CUMS upregulated the expressions of α2δ-1, N-methyl- d -aspartate receptor 1 (NR1), NR2A and NR2B, and enhanced the binding ability to of α2δ-1 and NR1, which were reversed by CLD. The results demonstrated that CLD could ameliorate depression-like behaviors due to CUMS, which was related to the fact that CLD down-regulated α2δ-1 level and interfered with α2δ-1 binding to NR1, thereby reducing NMDAR expression and ultimately inhibiting HPA axis activity.

Chitosan (CTS) exhibits notable moisturizing and film-forming capabilities, whereas nano selenium (SeNPs) demonstrates antioxidant and antibacterial properties. In the present study, a CTS/Se film-forming agent was prepared by dissolving CTS, glycerol, and SeNPs in 1% (v/v) glacial acetic acid through heating and ultrasonic treatment. The results revealed that SeNPs fused with CTS via intermolecular forces, thereby enhancing the tensile strength of the CTS film. The water contact angle of the CTS film increased with an increase in SeNPs concentration. The thermal stability and water retention properties of CTS/Se were superior than CTS. In a storage experiment, the content of soluble solids in tomatoes coated with CTS/Se was higher than that in tomatoes coated with CTS and the control. The CTS/Se coating inhibited gas exchange both inside and outside the film, leading to increased activities of antioxidant enzymes. This reduced the oxidation of vitamin C in the tomatoes and decreased the content of malondialdehyde. The CTS/Se film inhibited the growth of bacteria on the tomato surface and mitigated the decline of aldehyde, alcohol and ketone aroma compounds. Consequently, the CTS/Se coating alleviated the softening, aging and rotting of tomatoes. Feeding experiments conducted on mice verified the food safety of the CTS/Se.

Wound-induced suberization is an essentially protective healing process for wounded fruit to reduce water loss and microbial infection. It has been demonstrated that abscisic acid (ABA) could promote wound suberization, but the molecular mechanism of ABA regulation remains little known. In this study, the transcript level of Achn030011 (designated as AchnKCS), coding a β-ketoacyl-coenzyme A synthase (KCS) involved in suberin biosynthesis, was found to be significantly upregulated by ABA in wounded kiwifruit. A bZIP transcription factor (Achn270881), a possible downstream transcription factor in the ABA signaling pathway, was screened and designated as AchnbZIP12 according to its homology with related Arabidopsis transcription factors. A yeast one-hybrid assay demonstrated that AchnbZIP12 could interact with the AchnKCS promoter. Furthermore, significant trans-activation of AchnbZIP12 on AchnKCS was verified. The transcript level of AchnbZIP12 was also upregulated upon treatment with ABA. These results imply that AchnbZIP12 acts as a positive regulator in ABA-mediated AchnKCS transcription during wound suberization of kiwifruit.

The occurrence of chilling injury is closely related to changes in wax. In this study, we investigated the relationship in plum fruit between wax presence (CK) and removal of epicuticular wax (REW) based on micromorphology and metabolomics. The results showed that wax reduced the incidence of chilling injury in plum fruit and slowed down the rate of loss of fruit firmness, and that the abundant wax structure not only protected the epidermal cells but also inhibited high-intensity respiration of the fruit. The correlation analysis between wax components and chilling injury illustrated that triterpene components were positively correlated with the occurrence of chilling injury. In summary, the present study revealed that wax components were involved in regulating chilling injury in plums, which provides a research idea to delay and reduce the occurrence of chilling injury in plums.

To expand the utilization of discarded walnut shells and enhance the photocatalytic activity of graphitic carbon nitride(g-C 3 N 4 ), the carbon-rich graphitic carbon nitride anchored with Fe sites (FeW-CN) was synthesized via a walnut shell-based biochar-assisted strategy. Unlike the direct thermal copolymerization of melamine for g-C 3 N 4 , the iron-loaded walnut shell-based biochar (FeW) was first synthesized, followed by thermal copolymerization of melamine with FeW to form FeW-CN. The C substitution on the triazine ring enhanced the light absorption and electron migration for FeW-CN. And the Fe sites interacting with N-(C) 3 further improved the migration and the utilization rate of photogenerated carriers. During the degradation of 2-Mercaptobenzothiazole, FeW-CN showed excellent photocatalytic performance and stability compared with g-C 3 N 4 . Moreover, FeW-CN maintained excellent photocatalytic performance in river water. Combination of electron paramagnetic resonance with active species quenching experiments, the synergistic mechanism of singlet oxygen, holes, and superoxide radicals was confirmed in the FeW-CN system. Compared to g-C 3 N 4 , the Fe sites and C substitution enhanced the production of singlet oxygen.

To extend the shelf-life of cherry tomatoes infected with Botrytis cinerea , this study analyzed the effect of Pichia membranifaciens (PM) on a composite film of gelatin (Gel) and trehalose (Tre), and explored the effect of different concentrations of trehalose on the yeast in the bioactive film and its control effect on cherry tomatoes. Scanning electron microscopy showed that Tre/Gel-based film can be applied as effective carriers to protect the cellular integrity of PM. Fourier-transform infrared spectroscopy, thermogravimetric analysis, and tests of mechanical properties showed that there was interaction between PM and the Tre/Gel base film, which maintained the thermal stability of the base film. The addition of PM reduced the water vapor permeability, hygroscopicity, and moisture content of the Tre/Gel base film, effectively extending the active film's storage time. This study also explored the growth curve of PM and found that 15% trehalose was effective in maintaining PM activity and could result in a 30-day survival rate of 62% for PM in Tre/Gel films, with 72.41% inhibition of B. cinerea . Finally, the PM/Tre/Gel film significantly reduced the incidence of decay in cherry tomatoes and improved the storage quality and fungal resistance of the fruit. Thus, PM/Tre/Gel films may be applied as a new antifungal packaging material for the preservation of fresh fruit.

Quinoline is a representative refractory ammonia nitrogen contaminant in coking wastewater, which presents a hazard to the environment and humanity. Thus, effective settlement of quinoline is eagerly required. Nevertheless, existing adsorbents are expensive and inefficient in quinoline adsorption. It is significant to explore a low-cost and efficient adsorbent. Herein an environmental-friendly activated biochar derived from agricultural waste walnut shell was synthesized. Activated biochar displays large surface area, rich pores and high surface activity. The adsorption behavior of activated biochar was tested under static and dynamic adsorption systems. Activated biochar represents excellent adsorption performance and industrial application potential. Under the conditions of 298 K, 650 rpm and pH = 7, the activated biochar's saturated adsorption capacity and equilibrium time for quinoline are 342.56 mg g −1 and 20 min, respectively. After five adsorption-desorption cycles, the adsorption capacity retained 93.43 % of the incipient value, indicating that activated biochar exhibits excellent regeneration performance. Moreover, activated biochar could maintain good adsorption performance in real wastewater. More importantly, using walnut shell as the raw material could save costs and realize resource utilization. The negative Δ G θ and positive Δ H θ values demonstrate that the adsorption process is spontaneous and endothermic, which follows the pseudo-first-order kinetics and fits well with the Langmuir–Freundlich model. This work has a good guiding significance in the domain of sewage purification.

Oil bodies (OB) are naturally occurring pre-emulsified oil droplets with broad application prospects in emulsions and gels. In this study, the chitosan and vanillin with different concentrations were used as structuring agents for preparation of oleogels based on walnut OB (WOB), and the particle size, zeta potential, spectral, thermal characteristics, physical properties and in vitro simulated digestion of WOB oleogels were evaluated. These characteristics results showed that chitosan and vanillin were successfully cross-linked with WOB and formed a dense three-dimensional network structure. Spectral analysis results demonstrated that chitosan and vanillin could improve WOB properties mainly through hydrogen bond interaction, Schiff base crosslinking and electrostatic interaction. The physical properties analysis manifested that the cross-linked WOB oleogels had strong hardness (26.86 N), good thermal stability (ΔH = −442.16 J g -1 ), excellent structural recovery (0.90) and higher gel strength (G′> 9000 Pa). In vitro simulated gastrointestinal digestion manifested that cross-linking reduced the free fatty acids released from oleogels. The microstructure of digestates illustrated that this might be related to the compact coating formed by chitosan and the integrated network induced by vanillin. This study provided a novel strategy for using WOB to replace animal fats to produce healthy oleogels.

The objective of this study is to investigate the effects of carvacrol on the postharvest storage quality and cell wall metabolism of the ’Guichang’ kiwifruit. For this purpose, the ’Guichang’ kiwifruit is selected as the test material and treated with 0.03 mg/mL of a carvacrol solution for dipping. The storage quality and cell wall metabolism of the fruit are then evaluated under ambient conditions (20 ± 1 °C). The results indicate that treatment with carvacrol effectively reduces the postharvest respiration rate and weight loss in the kiwifruit, while preserving the levels of vitamin C (VC), soluble protein, total phenols, flavonoids, soluble solids, solid–acid ratio, and soluble pectin. Additionally, it delays the decline in the starch content and mitigates the increase in soluble sugars. Furthermore, carvacrol significantly decreases amylase activity and inhibits the elevation of polygalacturonase (PG), pectin methylesterase (PME),β-galactosidase (β-Gal), and cellulase (Cx) activity. Consequently, this treatment effectively maintains fruit firmness as well as protopectin (PP) and cellulose content at elevated levels. A correlation analysis shows that firmness is highly and negatively correlated with the cell wall degrading enzymes PG, PME, β-Gal, Cx, and α-L-Af, with R values of −0.88, −0.83, −0.98, −0.94, and −0.93, respectively. The negative correlation values for the control group are all lower than 0. In conclusion, treatment with carvacrol effectively preserves a high level of postharvest ripening quality in the kiwifruit, attenuates the metabolic processes of the cell wall, and delays fruit softening and senescence.

As a deep-processed product of peach, the aroma characteristics of peach spirit have not been systematically studied, and there has been no research on improving the aroma quality through process improvement. Pervaporation technology was used for the first time in the production of peach spirit instead of distillation, and its critical aroma compounds were analyzed compared with distilled peach spirit. Compared to the distilled peach spirit, pervaporation produced peach spirit presented stronger fruity, honey, and acidic aromas, and lighter cooked-apple aroma. Sixty-two and 65 aroma-active regions were identified in the distilled and pervaporation produced peach spirits, and 40 and 43 of them were quantified. The concentrations of esters, lactones, and acids were significantly higher in the pervaporation produced peach spirit than those in the distilled peach spirit, while terpenoids showed opposite tendency. Both of the overall aromas of distilled and pervaporation produced peach spirits were reconstituted successfully by the compounds with OAV ≥ 1. The omission tests identified 10 and 18 compounds as important aroma compounds for distilled and pervaporation-produced peach spirits, respectively. The differences in the key aroma compounds between the two types of peach spirits explained the differences in the aroma profiles.Keywords:peach spirit;distillation;pervaporation;aroma;sensomics approach

Sunflowers ( Helianthus annuus ) are potential trap crops to attract the yellow peach moth ( Conogethes punctiferalis ) in orchards but the volatile compounds released from sunflowers and their effects on C. punctiferalis behaviour are not clear. Here we used solid phase micro-extraction to collect volatiles released from flower disks of sunflowers, identified them by gas chromatography–mass spectrometry, and examined the attractiveness of some of the compounds to mated female adult C. punctiferalis moths in Y-tube olfactometer choice tests. We detected nine volatile compounds (α-Pinene, β-Phellandrene, Camphene, β-Pinene, 3-Carene, D-Limonene, Eucalyptol, γ-Terpinen, and Valencene) with consistently large peak areas for α-Pinene and β-Phellandrene. Among tested volatiles, both α-Pinene and β-Phellandrene were attractive to C. punctiferalis in olfactometer tests but this was only significant for higher concentrations of β-Phellandrene. This suggests that β-Phellandrene may promote C. punctiferalis oviposition on sunflower disks. This study provides insights into volatile chemical mediated responses of insect herbivores to trap crops.

The objective of this study was to determine the antioxidant activities of defatted walnut kernel extract (DWE) and whole walnut kernel extract (WE) in vitro and in vivo. Three spectrophotometric methods, DPPH, ABTS, and FRAP, were used in in vitro experiments, and mice were used in in vivo experiments. In addition, response surface methodology (RSM) was used to optimize reflux-assisted ethanol extraction of DWE for maximum antioxidant activity and total phenolic content. The results of in vitro experiments showed that both extracts showed antioxidant activity; however, the antioxidant activity of DWE was higher than that of WE. Both extracts improved the mice’s oxidative damage status in in vivo studies. An ethanol concentration of 58%, an extraction temperature of 48 °C, and an extraction time of 77 min were the ideal parameters for reflux-assisted ethanol extraction of DWE. The results may provide useful information for further applications of defatted walnut kernels and the development of functional foods.Keywords:walnut kernel;antioxidant activity;in vitro;in vivo;response surface methodology
