The role of Ginkgo Folium on antitumor: Bioactive constituents and the potential mechanism.

ETHNOPHARMACOLOGICAL RELEVANCE: Ginkgo biloba L. is a well-known and highly regarded resource in Chinese traditional medicine due to its effectiveness and safety. Ginkgo Folium, the leaf of Ginkgo biloba L., contains biologically active constituents with diverse pharmacological activities. Recent studies have shown promising antitumor effects of the bioactive constituents found in Ginkgo Folium against various types of cancer cells, highlighting its potential as a natural source of antitumor agents. Further research is needed to elucidate the underlying mechanisms and optimize its therapeutic potential. AIM OF THE REVIEW: To provide a detailed understanding of the pharmacological activities of Ginkgo Folium and its potential therapeutic benefits for cancer patients. MATERIALS AND METHODS: In this study, we conducted a thorough and systematic search of multiple online databases, including PubMed, Web of Science, Medline, using relevant keywords such as "Ginkgo Folium," "flavonoids," "terpenoids," "Ginkgo Folium extracts," and "antitumor" to cover a broad range of studies that could inform our review. Additionally, we followed a rigorous selection process to ensure that the studies included in our review met the predetermined inclusion criteria. RESULTS: The active constituents of Ginkgo Folium primarily consist of flavonoids and terpenoids, with quercetin, kaempferol, isorhamnetin, ginkgolides, and bilobalide being the major compounds. These active constituents exert their antitumor effects through crucial biological events such as apoptosis, cell cycle arrest, autophagy, and inhibition of invasion and metastasis via modulating diverse signaling pathways. During the process of apoptosis, active constituents primarily exert their effects by modulating the caspase-8 mediated death receptor pathway and caspase-9 mediated mitochondrial pathway via regulating specific signaling pathways. Furthermore, by modulating multiple signaling pathways, active constituents effectively induce G1, G0/G1, G2, and G2/M phase arrest. Among these, the pathways associated with G2/M phase arrest are particularly extensive, with the cyclin-dependent kinases (CDKs) being most involved. Moreover, active constituents primarily mediate autophagy by modulating certain inflammatory factors and stressors, facilitating the fusion stage between autophagosomes and lysosomes. Additionally, through the modulation of specific chemokines and matrix metalloproteinases, active constituents effectively inhibit the processes of epithelial-mesenchymal transition (EMT) and angiogenesis, exerting a significant impact on cellular invasion and migration. Synergistic effects are observed among the active constituents, particularly quercetin and kaempferol. CONCLUSION: Active components derived from Ginkgo Folium demonstrate a comprehensive antitumor effect across various levels and pathways, presenting compelling evidence for their potential in new drug development. However, in order to facilitate their broad and adaptable clinical application, further extensive experimental investigations are required to thoroughly explore their efficacy, safety, and underlying mechanisms of action.

Application of Insect Medicines in Treatment of Coronary Microvascular Dysfunction Based on Comorbidity Theory of "Blood-Vessel-Cardiac Collaterals" / 中国实验方剂学杂志

Coronary microvascular dysfunction （CMD） is one of the important causes of myocardial ischemia and non-obstructive coronary artery ischemic symptoms. However， effective diagnostic methods and targeted treatment strategies for CMD are currently lacking. According to traditional Chinese medicine （TCM）， the comorbidity theory of "blood-vessel-cardiac collaterals" plays a central role throughout the entire development process of CMD. It suggests that in the clinical diagnosis and treatment of CMD， the treatment of blood， vessels， and cardiac collaterals should not be neglected. In light of this， insect medicines， known for their efficacy in promoting blood circulation， resolving stasis， and alleviating spasms， hold promise as a potential treatment for CMD. However， there is currently no research or summary on the use of insect medicines for the treatment of CMD. Therefore， this article took the comorbidity theory of "blood-vessel-cardiac collaterals" as the starting point and divided the pathogenesis of CMD into five evolution stages： Beginning in the blood （changes in blood components and hemorheology）， progressing in the vessels （atheromatous plaque formation and unstable plaques）， occurring in the cardiac collaterals （microvascular endothelial damage and microvascular constriction and spasms）， ending in the cardiac collaterals （microvascular remodeling）， and resulting in energy metabolism disorders throughout the process， so as to explore the pathogenesis and evolution of CMD. In addition， based on the modern pharmacological research on insect medicines， this article discussed the clinical application of insect medicines in the treatment of CMD from four aspects： Promoting blood circulation and removing blood stasis to relieve vessels' obstruction， relieving spasms to alleviate pain， combating poison with poison to disperse stagnation， and tonifying cardiac collaterals to nourish the heart， which aims to provide a theoretical basis for the use of TCM in treating CMD， broaden the scope of medication， and improve clinical efficacy.

Inhibition of cell wall pectin metabolism by plasma activated water (PAW) to maintain firmness and quality of postharvest blueberry.

Blueberry is a class of berries with high nutritional and economic value but has short shelf life due to its rapid softening at room temperature. This study investigated the effects of plasma-activated water (PAW) treatment on the softening quality and cell wall pectin metabolism of blueberries stored for 10 d at 25 °C after being immersed in PAW for 10 min. PAW was generated by plasma with different times (1 and 2 min), fixed frequency (10 kHz) and fixed voltage (50 kV). The analysis showed that the firmness of PAW-treated fruit significantly increased (P < 0.05) by 36.4% after 10 d storage. PAW treatment controlled the solubilization of pectin from water-insoluble to water-soluble. The activities of cell wall pectin-degrading enzymes like polygalacturonase (PG), ß-galactosidase (ß-Gal) and pectin methylesterase (PME) in PAW-treated blueberries decreased by 15.7%, 18.3%, and 27.9%, respectively, on day 10. After PAW treatment, blueberries also maintained better postharvest quality (firmness, colour, soluble solid content and anthocyanin content) and intact epidermal waxy and cell wall structure. These results suggested that PAW showed great potential for postharvest fresh-keeping of blueberry.

Enhancement of Wheat Seed Germination, Seedling Growth and Nutritional Properties of Wheat Plantlet Juice by Plasma Activated Water.

Previous studies have shown the great potential of using plasma-activated water (PAW) on improving agriculture seed germination, however, information on the influence of PAW on crop plantlet juice remains scanty. In this research, the effect of PAW generated by atmosphere pressure Ar-O2 plasma jet for 1-5 min on wheat seed germination, seedling growth and nutritional properties of wheat plantlet juice was investigated. Results revealed that all PAWs could enhance wheat seed germination and seedling growth in 7 days by improving the germination rate, germination index, fresh weight, dry weight and vigour index, and especially that PAW activated for 3 min (PAW-3) showed the best overall performance. In addition, the application of PAWs enhanced the nutritional properties of wheat plantlet juice from those grown for 14 days by improving total soluble solids, protein content, photosynthetic pigments, total phenolic content, antioxidant activity, enzyme activity, free amino acids and minerals content, and the best enhancement was also observed in PAW-3. It was concluded that PAWs would be an effective technique to enhance the growth and nutritional properties of crop sprouts, which could be served as functional foods in many forms.

Role of Aquaporins in Heart Failure from Theory of Cardiac and Renal Coordination / 中国实验方剂学杂志

Heart failure refers to a group of clinical syndromes caused by structural or functional abnormalities of the heart that lead to impaired ejection or filling of the ventricles. The traditional Chinese medicine （TCM） theory of cardiac and renal coordination holds that the kidney governs water and plays a key role in maintaining the balance of fluid metabolism. Therefore， the treatment of water retention in heart failure can start from the heart and kidney. The basic pathogenesis of heart failure is kidney deficiency， blood stasis， and water stagnation， and the therapies including dredging the heart and kidneys， warming yang and excreting water， tonifying kidneys and activating blood， and dredging meridians and collaterals. Aquaporins （AQPs）， the key molecular basis of water metabolism， are involved in the pathogenesis of water retention in heart failure together with the arginine vasopressin system （AVP）， renin-angiotensin-aldosterone system （RAAS）， and diuretic resistance. Studies have shown that herbal medicines that regulate the heart and kidney can alleviate water retention in heart failure by targeting AQPs， thereby delaying or even reversing the progression of heart failure. This paper expounds the TCM name and pathogenesis of heart failure from the theory of cardiac and renal coordination， the role of AQPs in the pathogenesis of water retention in heart failure， and the modern connotation of the therapy of tonifying heart and kidney for heart failure， aiming to provide ideas for the prevention and treatment of water retention in heart failure by TCM.

Mechanisms of traditional Chinese medicine formulas and active ingredients in regulation of macrophage subsets involved in inflammation and repair of coronary heart disease / 中国中药杂志

Coronary artery disease(CAD) caused by atherosclerosis(AS) is a major contributor to the global burden of disease. The pathogenesis of CAD is complex, and the subset and function of cardiac macrophages are important factors affecting the occurrence and development of AS and the prognosis of CAD. Recent studies have shown that some traditional Chinese medicine(TCM) formulas and active ingredients can regulate macrophage subsets involved in the inflammation, injury, and repair process of CAD. This paper summarized the significant role of macrophages in AS and myocardial infarction. Based on the plasticity of macrophages, this paper elaborated that traditional Chinese medicine prevented and attenuated AS by regulating macrophage subsets, reducing the level of inflammatory factors, and promoting macrophage autophagy.Traditional Chinese medicine participated in the cardiac repair process after myocardial infarction by accelerating the recruitment of M2 macrophages, inhibiting the polarization of M1 macrophages mediated by glycolysis, inhibiting M1 macrophage-mediated cardiac nerve remodeling, and promoting M2 macrophage-mediated angiogenesis. In addition, in vitro studies on the regulation of macrophage subsets by the active ingredients of traditional Chinese medicine were also reviewed. It was pointed out that nuclear factor kappa B(NF-κB), adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK), phosphoinositide 3-kinase/protein kinase B(PI3K/Akt), chemokine(C-C motif) ligand 2/C-C chemokine receptor type 2(CCL2/CCR2) were the key targets and pathways for the regulation of macrophages by TCM.

Integrated strategy for biomarkers of stable coronary heart disease with phlegm and blood stasis syndrome based on RNA-seq and network pharmacology / 中国中药杂志

This study aimed to analyze the biological foundation and biomarkers of stable coronary heart disease(CHD) with phlegm and blood stasis(PBS) syndrome based on RNA-seq and network pharmacology. Peripheral blood nucleated cells from five CHD patients with PBS syndrome, five CHD patients with non-PBS syndrome, and five healthy adults were collected for RNA-seq. The specific targets of CHD with PBS syndrome were determined by differential gene expression analysis and Venn diagram analysis. The active ingredients of Danlou Tablets were screened out from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform, and the "component-target" prediction was completed through PubChem and SwissTargetPrediction. The "drug-ingredient-target-signaling pathway" network of Danlou Tablets against CHD with PBS syndrome was optimized by Cytoscape software. After the target biomarkers were identified, 90 participants were enrolled for diagnostic tests, and 30 CHD patients with PBS syndrome were included in before-and-after experiment to determine the therapeutic effect of Danlou Tablets on those targets. As revealed by RNA-seq and Venn diagram analysis, 200 specific genes were identified for CHD with PBS syndrome. A total of 1 118 potential therapeutic targets of Danlou Tablets were predicted through network pharmacology. Through integrated analysis of the two gene sets, 13 key targets of Danlou Tablets in the treatment of CHD with PBS syndrome were screened out, including CSF1, AKR1C2, PDGFRB, ARG1, CNR2, ALOX15B, ALDH1A1, CTSL, PLA2G7, LAP3, AKR1C3, IGFBP3, and CA1. They were presumably the biomarkers of CHD with PBS syndrome. The ELISA test further showed that CSF1 was significantly up-regulated in the peripheral blood of CHD patients with PBS syndrome, and was significantly down-regulated after Danlou Tablets intervention. CSF1 may be a biomarker for CHD with PBS syndrome, and it is positively correlated with the severity of the disease. The diagnostic cut-off of CSF1 for CHD with PBS syndrome was 286 pg·mL~(-1).

Arsenic Content in Cordyceps： A Review / 中国实验方剂学杂志

Cordyceps， a unique precious Chinese herbal medicine in China， has the effects of tonifying the kidney and lungs， stopping bleeding， and resolving phlegm. It has definite clinical effects on diabetes， respiratory diseases （such as chronic obstructive pulmonary disease）， chronic kidney diseases， slow arrhythmia， and hyperlipidemia. We searched China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， SpringerLink （Biomedical Sciences）， Embase， Proquest （Life Sciences）， PubMed， Cochrane Library， and SinoMed for the research on the arsenic content in Cordyceps. According to statistical analysis， arsenic in Cordyceps mainly exists in the non-toxic or low-toxic form. The arsenic-containing compounds in Cordyceps may be an arsenic-sugar compound with anticancer effect. The inorganic arsenic content in Cordyceps is lower than the arsenic standard stipulated by the State Food and Drug Administration. It remains uncertain whether different measurement methods can affect the results. The total arsenic content varies in Cordyceps from different producing areas， and the general rule of total arsenic content in Cordyceps produced in different provinces， districts， and counties cannot be obtained from the results of the existing studies. The arsenic content in Cordyceps is mainly concentrated in the insect part， which is significantly different from that in stroma， and no arsenic is detected in the mycelia. The soil arsenic content in the growing areas is generally high， which may be a main reason for the high arsenic content in Cordyceps. As a valuable medicinal material for tonifying and nourishing， Cordyceps still plays an irreplaceable role in disease prevention， health care， chronic disease management， and rehabilitation.

[Characteristics of Soil Organic Carbon Components and Their Correlation with Other Soil Physical and Chemical Factors in Cotton Fields with Different Continuous Cropping Years in the Oasis on the Northern Edge of Tarim Basin].

The study of soil organic carbon components in continuous cropping cotton fields in oases is helpful to reveal the change characteristics of the soil organic carbon stability mechanism in arid areas under the effects of man-land relationships. In this study, the contents of soil organic carbon, easily oxidized organic carbon, dissolved organic carbon, and microbial biomass carbon in cotton fields with different continuous cropping years (2 a, 5 a, 12 a, 20 a, and 35 a) were collected and analyzed by using space instead of the time series method. Through redundancy analysis, the relationship between soil organic carbon components and other soil physical and chemical factors was discussed. The results showed that:① continuous cropping for different years had a significant impact on the content of soil organic carbon components in the study area. The contents of soil organic carbon, easily oxidized organic carbon, dissolved organic carbon, and microbial biomass carbon in continuous cropping cotton fields for 12 a, 20 a, and 35 a were higher than those in continuous cropping cotton fields and wasteland for 2 a and 5 a. ω(soil organic carbon) reached the peak value (7.06 g·kg-1) in the cotton field in 20 a, which was 76.91% higher than that in the wasteland. The content of soil organic carbon decreased with the deepening of the soil layer. ② Based on the redundancy analysis of soil organic carbon content and soil environmental factors, the results showed that the content of soil organic carbon was positively correlated with total nitrogen, available phosphorus, and water content and negatively correlated with pH value and bulk density. The importance of soil environmental factors on the interpretation of soil organic carbon content was as follows:total N>available P>pH value>bulk density>water content>available K>total salt.

Influence of mild oxidation induced through DBD-plasma treatment on the structure and gelling properties of glycinin.

The effects of dielectric-barrier discharge (DBD) plasma treatment (20 s to 120 s treatment time with 40 kV, 12 kHz) induced mild oxidation on the gelling properties, and related structural changes of glycinin were investigated. The gelling ability of glycinin was improved by the mild oxidation induced by the plasma treatment. Treated glycinin gels exhibited a continuous and uniform network microstructure. Samples treated for 120 s had a 2.07-, 3.99- and 2.03-fold increase in hardness, chewiness, and resilience compared to the 20 s treated samples. Structural analyses showed that primary and secondary structures of glycinin were unaffected. The tertiary structure was shifted, accompanied by a decrease in free sulfhydryl (-SH) content. At the same time, carbonyl content and average particle diameter were increased by DBD treatment. The DBD treatment facilitated the generation/exchange of intermolecular disulfide bonds and enhanced gelling properties of glycinin. It is concluded that controlled plasma-induced protein oxidation can improve protein functionality.

Effects of combined treatment of plasma activated liquid and ultrasound for degradation of chlorothalonil fungicide residues in tomato.

The effects of combined treatment (PAL-U) of plasma-activated liquid (PAL) including plasma-activated water (PAW) and plasma-activated buffer solution (PABS) and ultrasound (U) for the degradation of chlorothalonil fungicide on tomato fruit was investigated. Distilled water and buffer solution were activated by radiofrequency plasma jet for durations of 1, 3, 5, and 10 min to obtain PAL1 to PAL10. Fruits were immersed in PAL for 15 min and also in distilled water with sonication for 15 min for individual treatments, and in PAL with sonication for 15 min for combined treatments. The maximum chlorothalonil fungicide residues were reduced by 89.28 and 80.23% for PAW10-U and PABS10-U, respectively. HPLC-MS characterization revealed chlorothalonil degradation pathway and formation of 2,4,5-trichloroisophthalonitrile, 2,4-dichloroisophthalonitrile, 4-chloroisophthalonitrile, isophthalonitrile and phenylacetonitrile as degradation products. Treatments also showed no negative effects on tomato quality. Therefore, PAL and PAL-U treatments could serve as effective methods for degrading pesticides on tomatoes.

Quality value transfer of substance benchmarks in Sanpian Decoction / 中国中药杂志

According to the polarity of different components in Sanpian Decoction, two fingerprints were established. Then the substance benchmark freeze-dried powder of 15 batches of Sanpian Decoction was prepared, followed by the determination of the fingerprints, index component content, and dry extract rates, the identification of attribution of characteristic peaks, and the calculation of similarities between these fingerprints and the reference(R), the content and transfer rate ranges of ferulic acid, sinapine thiocyanate, liquiritin, and glycyrrhizic acid, and the dry extract rate range. The results showed that the similarities of 15 batches of the substance benchmark fingerprints with R were all greater than 0.900.Further summarization of the characteristic peaks revealed that there were a total of 20 characteristic peaks in fingerprint 1, among which, eight were from Sinapis Semen, four from Paeoniae Radix Alba, six from Chuanxiong Rhizoma, and two from Glycyrrhizae Radix et Rhizoma. A total of 16 characteristic peaks were observed in fingerprint 2, including one from Sinapis Semen, three from Paeoniae Radix Alba, eight from Chuanxiong Rhizoma, and four from Glycyrrhizae Radix et Rhizoma. The average dry extract rate of 15 batches of substance benchmarks was 18.25%, with a dry extract rate range of 16.28%-20.76%. The index component content and transfer rate ranges were listed as follows: 0.15%-0.18% and 38.81%-58.05% for ferulic acid; 0.26%-0.42% and 36.51%-51.02% for sinapine thiocyanate; 0.09%-0.15% and 48.80%-76.61% for liquiritin; 0.13%-0.24% and 23.45%-35.61% for glycyrrhizic acid. The fingerprint, dry extract rate, and index component content determination was combined for analyzing the quality value transfer of substance benchmarks in the classic prescription Sanpian Decoction.The established quality evaluation method for the substance benchmarks was stable and feasible, which has provided a basis for the quality control of Sanpian Decoction and the follow-up development of related preparations.

Components of drugs in acupoint sticking therapy and its mechanism of intervention on bronchial asthma based on UPLC-Q-TOF-MS combined with network pharmacology and experimental verification / 中国中药杂志

UPLC-Q-TOF-MS combined with network pharmacology and experimental verification was used to explore the mechanism of acupoint sticking therapy(AST) in the intervention of bronchial asthma(BA). The chemical components of Sinapis Semen, Cory-dalis Rhizoma, Kansui Radix, Asari Radix et Rhizoma, and Zingiberis Rhizoma Recens were retrieved from TCMSP as self-built database. The active components in AST drugs were analyzed by UPLC-Q-TOF-MS, and the targets were screened out in TCMSP and Swiss-TargetPrediction. Targets of BA were collected from GeneCards, and the intersection of active components and targets was obtained by Venny 2.1.0. The potential targets were imported into STRING and DAVID for PPI, GO, and KEGG analyses. The asthma model induced by house dust mite(HDM) was established in mice. The mechanism of AST on asthmatic mice was explored by pulmonary function, Western blot, and flow cytometry. The results indicated that 54 active components were obtained by UPLC-Q-TOF-MS and 162 potential targets were obtained from the intersection. The first 53 targets were selected as key targets. PPI, GO, and KEGG analyses showed that AST presumedly acted on SRC, PIK3 CA, and other targets through active components such as sinoacutine, sinapic acid, dihydrocapsaicin, and 6-gingerol and regulated PI3 K-AKT, ErbB, chemokine, sphingolipid, and other signaling pathways to intervene in the pathological mechanism of BA. AST can improve lung function, down-regulate the expression of PI3 K and p-AKT proteins in lung tissues, enhance the expression of PETN protein, and reduce the level of type Ⅱ innate immune cells(ILC2 s) in lung tissues of asthmatic mice. In conclusion, AST may inhibit ILC2 s by down-regulating the PI3 K-AKT pathway to relieve asthmatic airway inflammation and reduce airway hyperresponsiveness.

Oxidation induced by dielectric barrier discharge (DBD) plasma treatment reduces IgG/IgE binding capacity and improves the functionality of glycinin.

The effect of dielectric barrier discharge (DBD) plasma treatment times from 2 to 5 min at 40 kV on IgG/IgE binding capacity and functionality of soybean glycinin was examined. A substantial reduction in the binding capacity (91.64% for IgG and 81.49% for IgE) was obtained after 5 min of plasma treatment, as determined by western-blot and ELISA analyses. Further studies demonstrated that the elimination of antigenicity and allergenicity of glycinin was directly related to plasma-induced structural changes on two aspects. A conformational alteration caused by oxidation of peptide bond amino groups, accompanied with an oxidation of Trp, Tyr, and Phe amino acid residues, which was confirmed by surface hydrophobicity, multi-spectroscopic analysis, and amino acid analysis. The cleavage of polypeptide chains inevitably partially diminished the linear epitopes, resulting in a primary decline in IgG/IgE binding capacity. Additionally, an increase in the solubility from 10.78 ± 0.35 to 65.96 ± 1.86% and significant increase in the emulsifying ability from 21.08 ± 2.64 to 160.29 ± 4.12 m2/g were observed after treatment of the plasma for 2 min. The present results confirm the potential use of DBD for the production of hypoallergenic soy protein-based products and improving their technical functions such as solubility and emulsifying ability.

Oxidation induced by dielectric-barrier discharge (DBD) plasma treatment reduces soybean agglutinin activity.

In this study, potential of dielectric-barrier discharge (DBD) plasma treatment (40 kV, 12 kHz at 1, 2, 3 and 4 min) to eliminate soybean agglutinin (SBA) activity was investigated in a SBA model system and soymilk. The plasma treatment decreased the SBA in the model system and hemagglutination activity was decreased by 87.31%. SDS-PAGE analysis confirmed the degradation of the SBA polypeptide chain. The multi-spectroscopic analysis revealed a two-stage structure alteration in the SBA upon exposure to the plasma treatment. Oxidation of NH-/NH2- at the peptide bond disrupted the hydrogen bonds and altered the secondary structure of SBA. Further oxidation of aromatic amino acid, cleavage of peptide bonds and the breakage of polypeptide led to the SBA fragmentation and complete unfolding of the protein. The SBA inactivation by the plasma treatment was confirmed in soymilk. Plasma treatment is a promising technology for the elimination of SBA in soybean product.

Objective: To observe the clinical efficacy of Tuina (Chinese therapeutic massage) manipulation for pediatric adenoid hypertrophy (AH). Methods: A total of 60 children with AH were randomized into an observation group and a medication group, with 30 cases in each group. The observation group was treated with pediatric Tuina treatment, and the medication group was treated with 0.05％ mometasone furoate nasal spray. The changes of main clinical symptom score, quality of life (QOL) score and X-ray nasopharynx lateral film were observed, and the clinical efficacy was evaluated. Results: The total effective rate of the observation group was 90.0％, and that of the medication group was 66.7％. The difference between the two groups was statistically significant (P<0.05). After treatment, the A/N value [ratio of adenoid thickness (A) and nasopharyngeal cavity width (N)] of posterior nasopharyngeal lateral film did not show significant change in either group (P>0.05). After treatment, the clinical symptom scores in both groups decreased, and the intra-group differences were statistically significant (P<0.001), but there was no statistical difference between the two groups (P>0.05). After treatment, the QOL scores of children in both groups decreased, and the intra-group differences were statistically significant (P<0.001), and the difference between the two groups was statistically significant (P<0.001). Conclusion: Tuina manipulation is effective in treating pediatric AH, and produces a better effect in improving traditional Chinese medicine symptoms and QOL than 0.05％ mometasone furoate nasal spray.

Chemical, physical and physiological quality attributes of fruit and vegetables induced by cold plasma treatment: Mechanisms and application advances.

In recent years, applications of cold plasma treatments have shown high efficiency in sterilization of fresh fruit and vegetables. With encouraging results, development of this technique focuses on influences of cold plasma on the quality attributes of these fresh produce. More studies found that the quality attributes are maintained in an acceptable range or can even be improved under certain plasma treatment conditions. This review provides an overview of the multiple effects of cold plasma on the fresh produce, in terms of physical, chemical and physiological aspects. Besides, the possible mechanisms of how plasma influences these quality attributes is elaborated, which is useful for further modification and improvement of the plasma technology, so that quality enhancement and shelf life extension can be achieved. Future trends in the development of cold plasma technology are also presented. Cold plasma treatment is a potential technology for treating fresh fruit and vegetables to enhance their quality and extend their shelf life. However, knowledge of the effects of cold plasma on the quality changes of fresh fruit and vegetables is still limited. Therefore, there is a need for future studies to understand the mechanisms of plasma effects on controlling the interactions between plasma and food products in order to realize the early adoption of the technology to the food industry.
