Light-emitting diode irradiation at 590nm combined with active substances modulates ultraviolet B radiation-induced keratinocyte inflammation.

To evaluate the efficacy of yellow light-emitting diode (LED) irradiation at 590 nm, alone or in combination with anti-inflammatory active substances against ultraviolet (UV)-induced inflammation in keratinocytes. HaCaT keratinocytes were pretreated with LED yellow light (590 nm) alone or in combination with an antiinflammatory active substance such as glycerophosphoinositol choline (GC), extract of grains of paradise (Aframomum melegueta Schum, AM), or a bisabolol and ginger root extract mixture (Bb-GE) before UVB irradiation. Following each treatment, we measured the levels of inflammatory mediators secreted by keratinocytes. HaCaT keratinocytes treated with UVB (300mJ cm-²) and then cultured for 24h exhibited significantly upregulated expression of proinflammatory factors, including interleukin (IL)-1α, prostaglandin E2 (PGE2), and IL-8. After pretreatment with 590nm LED, UVB-induced inflammatory responses were significantly inhibited. Co-pretreatment with 590nm LED irradiation and GC further inhibited the expression of IL-1α and IL-8. IL-8 expression was inhibited by co-pretreatment with 590nm LED irradiation and AM, whereas PGE2 expression was inhibited by co-pretreatment with 590nm LED irradiation and Bb-GE. Co-treatment with 590nm LED irradiation and various active substances modulated UVB-induced inflammation in keratinocytes, suggesting the potential application of this approach to prevent damage caused by voluntary sun exposure in daily life.

Biomimetic nanoplatform with microbiome modulation and antioxidant functions ameliorating insulin resistance and pancreatic β-cell dysfunction for T2DM management

Insulin resistance and pancreatic β-cell dysfunction are the main pathogenesis of type 2 diabetes mellitus (T2DM). However, insulin therapy and diabetes medications do not effectively solve the two problems simultaneously. In this study, a biomimetic oral hydrogen nanogenerator that leverages the benefits of edible plant-derived exosomes and hydrogen therapy was constructed to overcome this dilemma by modulating gut microbiota and ameliorating oxidative stress and inflammatory responses. Hollow mesoporous silica (HMS) nanoparticles encapsulating ammonia borane (A) were used to overcome the inefficiency of H2 delivery in traditional hydrogen therapy, and exosomes originating from ginger (GE) were employed to enhance biocompatibility and regulate intestinal flora. Our study showed that HMS/A@GE not only considerably ameliorated insulin resistance and liver steatosis, but inhibited the dedifferentiation of islet β-cell and enhanced pancreatic β-cell proportion in T2DM model mice. In addition to its antioxidant and anti-inflammatory effects, HMS/A@GE augmented the abundance of Lactobacilli spp. and tryptophan metabolites, such as indole and indole acetic acid, which further activated the AhR/IL-22 pathway to improve intestinal-barrier function and metabolic impairments. This study offers a potentially viable strategy for addressing the current limitations of diabetes treatment by integrating gut-microbiota remodelling with antioxidant therapies.

Dehydration of Ginger (Zingiber officinale Roscoe) and Its Effect on Water Flavoring

Dehydration of Ginger (Zingiber officinale Roscoe) and Its Effect on Water Flavoring

Development of a determination method for quality control markers utilizing metabolic profiling and its application on processed Zingiber officinale Roscoe rhizome.

This study established an Orthogonal Partial Least Squares (OPLS) model combining 1H-NMR and GC-MS data to identify characteristic metabolites in complex extracts. Both in metabolomics studies, and natural product chemistry, the reliable identification of marker metabolites usually requires laborious isolation and purification steps, which remains a bottleneck in many studies. Both ginger (GR) and processed ginger (PGR) are listed in the Japanese pharmacopeia. The plant of origin, the rhizome of Zingiber officinale Roscoe, is differently processed for these crude drugs. Notably, the quality of crude drugs is affected by genetic and environmental factors, making it difficult to maintain a certain quality standard. Therefore, characteristic markers for the quality control of GR and PGR are required. Metabolomic analysis using 1H-NMR was able to discriminate between GR and PGR, but there were unidentified signals that were difficult to distinguish based on NMR data alone. Therefore, we combined 1H-NMR and GC-MS analytical data to identify them by OPLS. As a result, αr-curcumene was found to be a useful marker for these identifications. This new approach enabled rapid identification of characteristic marker compounds and reduced the labor involved in the isolation process.

Optimization, molecular dynamics and quantum parameters simulations of Zingiber officinale rhizome as a green corrosion inhibitor

This study combines experimental and theoretical approaches to investigate ginger root extract (GRE) as an eco-friendly corrosion inhibitor for mild steel in acidic environments at temperatures ranging from 303 to 333 K. Experimental techniques, including weight loss measurements, were used to assess the inhibiting performance and adsorption behavior of GRE, while GC-MS, FT-IR, and UV–visible spectrophotometric methods provided further characterization. Results indicated that the inhibition efficiency of GRE increased with higher concentrations and decreased with temperature, highlighting its potential to effectively prevent corrosion in H2SO4 medium. GC-MS analysis identified four major phenolic compounds—6-gingerol, 6-isoshogaol, zingerone, and vanillyl glycol—and two secondary metabolites, α-Farnesene and β-Bisabolene. Among these, 6-gingerol, the most active and abundant constituent, was selected for computational studies. Optimal corrosion inhibition of 81.3 % was achieved at 303 K with a GRE concentration of 10 g/L for 1 h. Thermodynamic activation parameters suggested a temperature-dependent process, and alignment with the Langmuir isotherm indicated a physical adsorption mechanism. Quantum chemical calculations for 6-gingerol revealed highest occupied molecular orbital energy (EHOMO) and lowest unoccupied molecular orbital energy (ELUMO) values of -6.286 eV and -0.366 eV, respectively, in its protonated state, and -8.338 eV and -0.247 eV, respectively, in its neutral state. Molecular simulations showed a binding affinity of -4.736 kJ/mol between 6-gingerol and the steel surface, supporting the experimental findings and underscoring the potential of GRE as an effective corrosion inhibitor.

The hemostatic activity and Mechanistic roles of glucosyloxybenzyl 2-isobutylmalate extract (BSCE) from Bletilla striata (Thunb.) Rchb.f. in Inhibiting pulmonary hemorrhage

BackgroundHemorrhagic events cause numerous deaths annually worldwide, highlighting the urgent need for effective hemostatic drugs. The glucosyloxybenzyl 2-isobutylmalates Control Extract (BSCE) from the orchid plant Bletilla striata (Thunb.) Rchb.f. has demonstrated significant hemostatic activity in both in vitro and in vivo studies. However, the effect and mechanism of BSCE on non-traumatic bleeding remain unclear. MethodsPulmonary hemorrhage was induced in 40 Sprague-Dawley rats by administering Zingiber officinale Roscoe. for 14 days. These rats were then randomly divided into five groups: model (Mod), positive control (YNBY), and BSCE low, medium, and high-dose groups. An additional 8 rats served as the control group (Con). The BSCE groups received different doses of BSCE for 10 days, while the YNBY group received Yunnan Baiyao suspension. The effects on body weight, food and water intake, red blood cell count (RBC), hemoglobin concentration (HGB), lung tissue pathology, platelet count, coagulation parameters, and fibrinolytic system markers were evaluated. Network pharmacology and molecular docking analyses were also conducted to identify potential targets and pathways involved in BSCE's effects. ResultsBSCE treatment significantly improved body weight, food intake, and water consumption in rats with pulmonary hemorrhage. RBC and HGB levels increased significantly in the BSCE medium and high-dose groups compared to the Mod group (P < 0.05). Pathological examination revealed that BSCE reduced lung tissue hemorrhage and inflammation, with improvements in alveolar structure. BSCE also positively affected platelet count, thrombin time (TT), activated partial thromboplastin time (APTT), fibrinogen (FIB) levels, and fibrinolytic markers (D-dimer, PAI-1, and t-PA). Network pharmacology and molecular docking identified key targets such as MMPs, CASPs, and pathways including IL-17 and TNF signaling, suggesting BSCE's involvement in hemostasis and anti-inflammatory processes. ConclusionsBSCE exhibits significant hemostatic and protective effects on Z.officinale-induced pulmonary hemorrhage in rats by improving hematological parameters, reducing lung tissue damage, and modulating the coagulation and fibrinolytic systems. The study provides evidence supporting the potential of BSCE as a therapeutic agent for hemorrhagic diseases, with its efficacy linked to multi-target and multi-pathway interactions.

Genome-wide investigation of the nuclear factor Y gene family in Ginger (Zingiber officinale Roscoe): evolution and expression profiling during development and abiotic stresses

BackgroundNuclear factor Y (NF-Y) plays a vital role in numerous biological processes as well as responses to biotic and abiotic stresses. However, its function in ginger (Zingiber officinale Roscoe), a significant medicinal and dietary vegetable, remains largely unexplored. Although the NF-Y family has been thoroughly identified in many plant species, and the function of individual NF-Y TFs has been characterized, there is a paucity of knowledge concerning this family in ginger.MethodsWe identified the largest number of NF-Y genes in the ginger genome using two BLASTP methods as part of our ginger genome research project. The conserved motifs of NF-Y proteins were analyzed through this process. To examine gene duplication events, we employed the Multiple Collinearity Scan toolkit (MCScanX). Syntenic relationships of NF-Y genes were mapped using the Dual Synteny Plotter software. Multiple sequence alignments were performed with MUSCLE under default parameters, and the resulting alignments were used to generate a maximum likelihood (ML) phylogenetic tree with the MEGA X program. RNA-seq analysis was conducted on collected samples, and statistical analyses were performed using Sigma Plot v14.0 (SYSTAT Software, USA).ResultsIn this study, the ginger genome was utilized to identify 36 NF-Y genes (10 ZoNF-YAs, 16 ZoNF-YBs, and 10 ZoNF-YCs), which were renamed based on their chromosomal distribution. Ten distinct motifs were identified within the ZoNF-Y genes, with certain unique motifs being vital for gene function. By analyzing their chromosomal location, gene structure, conserved protein motifs, and gene duplication events, we gained a deeper understanding of the evolutionary characteristics of these ZoNF-Y genes. Detailed analysis of ZoNF-Y gene expression patterns across various tissues, performed through RNA-seq and qRT-PCR, revealed their significant role in regulating ginger rhizome and flower growth and development. Additionally, we identified the ZoNF-Y family genes that responded to abiotic stresses.ConclusionThis study represents the first identification of the ZoNF-Y family in ginger. Our findings contribute to research on evolutionary characteristics and provide a better understanding of the molecular basis for development and abiotic stress response. Furthermore, it lays the foundation for further functional characterization of ZoNF-Y genes with an aim of ginger crop improvement.

Potentials of Zingiber officinale and Allium sativum ethanol extracts to inhibit oxidative stress and inflammation resulting from cancer inducement with 7,12-dimethylbenz[a]anthracene

Oxidative stress is the outcome of an imbalance between systemic manifestation of reactive oxygen species and a biological systems ability to readily detoxify the reactive intermediates in order to repair the resulting damage. This imbalance causes toxic effects through production of peroxides and free radicals. This study evaluated the potentials of Zingiber officinale and Allium sativum ethanol extracts to inhibit oxidative stress and inflammation resulting from cancer inducement with 7,12-dimethylbenz[a]anthracene (DMBA) using female Swiss virgin Albino rats of 7–8 weeks old. The plants were extracted with ethanol and assayed for tumor necrosis factor-alpha (TNF-α) and nuclear factor kappa B (NFk-β) to indicate inflammatory responses; malondialdehyde, superoxide dismuthase, catalase and glutathione as indicators of oxidative stress.. All assays were done using standard methods. Phytocompounds in Zingiber officinale were: alkaloids, tannins, flavonoids, steroids and terpenoids while those in Allium sativum were alkaloids, saponins, flavonoids, and glycosides. The actual lethal doses (LD50) of Zingiber officinale, Allium sativum and combination of the two were 8,660, 4,472, and 5,477 mg/kg body weight respectively. Zingiber officinale and Allium sativum ethanol extracts either as mono-therapy or in combination decreased the serum levels of malondialdehyde, and increased superoxide dismuthase, catalase and glutathione. They also decreased tumor necrosis factor-alpha and nuclear factor kappa B significantly (p˂0.05) when compared with control group. These were most remarkable in group 8. In conclusion, Zingiber officinale and Allium sativum ameliorated the oxidative stress and inflammation responses most remarkably when given at the proportion of ZO:AS = 6:4 (318:212 mg/kg body weight).

Assessing the impact of cold plasma rotational dynamics on ginger's total phenolic content, antioxidant activity, surface structure and color using response surface methodology

This study investigated the efficacy of a rotational chamber in enhancing the effectiveness of cold plasma application to augment antioxidant activity and phenolic content in ginger (Zingiber officinale). To address the limitation of cold plasma (CP), which predominantly treats only the surface layers of samples, we implemented rotational techniques during the treatment. This methodology facilitates a more uniform treatment, ensuring that all layers of the samples are effectively exposed to plasma. We employed response surface methodology (RSM) to analyze the effects of three variables: power (10–90 W), treatment time (1–30 min), and pressure (0.4–0.9 mbar), along with a categorical variable for rotation. CP treatment (65 W, 0.7 mbar, 1 min with rotation) resulted in a significant increase in antioxidant activity compared to non-treated samples, determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric-reducing antioxidant power (FRAP), and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) ABTS assays, and total phenolic content reaching their highest values of 100.9 Trolox equivalent (TE) μmol⋅L−1, 8.23 Fe2+⋅g−1, 0.293 μmol⋅g−1, and 32.80 gallic acid equivalent (GAE)/g, respectively. There were no significant changes in color. Scanning Electron Microscopy (SEM) analysis revealed that the samples treated with CP exhibited a smoother surface, albeit with minimal damage to cell walls in our selected samples. Including a rotational feature as a unique upgrade to the cold plasma, the glow discharge device demonstrated positive enhancements and preservation of antioxidant activity and phenolic compounds.
