Abstract
BACKGROUND Pulmonary fibrosis (PF) is an escalating global health issue, characterized by rising rates of morbidity and mortality annually. Consequently, further investigation of potential damage mechanisms and potential preventive strategies for PF are warranted. Specnuezhenide (SPN), a prominent secoiridoid compound derived from Ligustrum lucidum Ait, exhibits anti-inflammatory and anti-oxidative capacities, indicating the potential therapeutic actions on PF. However, the underlying mechanisms of SPN on PF remain unclear. PURPOSE This work was aimed at investigating the protective actions of SPN on PF and the potential mechanism. METHODS In vivo, mice were administrated with bleomycin (BLM) to establish PF model. PF mice were treated with SPN (45/90 mg/kg) by gavage. In vitro, we employed TGF-β1 (10 ng/mL)-induced MLE-12 and PLFs cells, which then were treated with SPN (5, 10, 20 µM). DARTS assay, biofilm interference experiment and molecular docking were performed to investigate the molecular target of SPN. RESULTS In vivo, we found SPN treatment improved survival rate, alleviated pathological changes through reducing BLM-induced extracellular matrix (ECM) deposition, as well as BLM-induced epithelial-mesenchymal transition (EMT). In vitro, SPN inhibited EMT and lung fibroblast transdifferentiation. Mechanistically, SPN activated the AMPK protein to decrease the abnormally high level of PD-L1. Furthermore, the compound C, known as an AMPK inhibitor, exhibited a significant hindrance to the inhibition of SPN on TGF-β1-caused fibroblast transdifferentiation and proliferation. This outcome could be attributed to the fact that compound C could eliminate the inhibitory effects of SPN on PD-L1 expression. Interestingly, DARTS assay, biofilm interference experiment and molecular docking results all indicated that SPN could bind to AMPK, which suggested that SPN might be a potential agonist targeting AMPK protein. CONCLUSION Altogether, the results in our work illustrated that SPN promoted AMPK-dependent reduction of PD-L1 protein, contributing to the inhibition of fibrosis progression. Thus, SPN may represent a potential AMPK agonist for PF treatment.

Novel inhibitory effect of black chokeberry ( Aronia melanocarpa) from selected eight berries extracts on advanced glycation end-products formation and corresponding mechanism study.

Abstract
Numerous health hazards have been connected to advanced glycation end products (AGEs). In this investigation, using reaction models including BSA-fructose, BSA- methylglyoxal (MGO), and BSA-glyoxal (GO), we examined the anti-glycation potential of eight different berry species on AGEs formation. Our results indicate that black chokeberry (Aronia melanocarpa) exhibited the highest inhibitory effects, with IC50 values of 0.35 ± 0.02, 0.45 ± 0.03, and 0.48 ± 0.11 mg/mL, respectively. Furthermore, our findings suggest that black chokeberry inhibits AGE formation by binding to BSA, which alleviates the conformation alteration, prevents protein cross-linking, and traps reactive α-dicarbonyls to form adducts. Notably, three major polyphenols, including cyanidin-3-O-galactoside, cyanidin-3-O-arabinoside, and procyanidin B2 from black chokeberry, showed remarkably inhibitory effect on MGO/GO capture, and new adducts formation was verified through LC-MS/MS analysis. In summary, our research provides a theoretical basis for the use of berries, particularly black chokeberry, as natural functional food components with potential anti-glycation effects.

Abstract
The eelgrass Zostera marina L. has several economic roles, from its earlier usage in the insulation industry to protecting the earth from global warming. In this study, we aimed to discover the cosmetic potential of Z. marina. A methanolic extract of Z. marina showed anti-phototoxicity and anti-melanogenesis activity with an IC50 of 17.5 μM, followed by a phytochemical analysis of its phenolic constituents. Ten compounds (1-10) were isolated by several chromatographic techniques and identified by means of nuclear magnetic resonance spectroscopy (NMR) as well as high-resolution mass spectrometry (HR/MS). The identified compounds are caffeic acid (1), 3,4-dihydroxybenzoic acid (protocatechuic acid) (2), luteolin (3), diosmetin (4), 4-coumaroyl-4'-hydroxyl phenyllactic acid (5), rosmarinic acid (6), caffeoyl-4'-hydroxy-phenyllactic acid (isorinic acid) (7), apigenin 7-O-β-D-glucopyranoside (8), luteolin 7-O-β-D-glucopyranoside (9), and luteolin 7-sulfate (10). This is the first report to identify compounds 5 and 7 from the family Zosteraceae. The isolated compounds were assessed for their anti-aging abilities and were found to exhibit good anti-phototoxicity and anti-melanogenesis activities by increasing the viability of UVB-irradiated HaCaT cells by 6% to 34% and by inhibiting melanin synthesis in B16 melanoma cells by 44% to 65%.

Abstract
Three prenylated flavonoids (1-3) were isolated from Tetragonula biroi propolis. The structures of the isolated compounds were characterized by NMR, IR, and UV spectroscopic and mass spectrometric analyses. The cytotoxicity activity of the crude extracts, fractions and the isolated compounds were established against four cell lines such as Caco-2, HeLa, MCF-7, and OVK-18. Among the tested compounds, compound 1 showed cytotoxicity activity against MCF-7 cell lines, whereas compound 2 showed good activity against Caco-2 and OVK-18 cell lines with IC50 values of 14.73 and 14.44, respectively. Moreover, compound 3 exhibited strong activity against OVK-18 cell lines. These findings contribute to the phytochemical understanding of the T. biroi propolis, and their cytotoxicity effects for future pharmaceutical purposes.

Abstract
An eco-friendly dispersive liquid-liquid microextraction mediated with a reverse micelle and coupled to an HPLC-DAD was developed for the simultaneous determination of venlafaxine and agomelatine in dosage forms and human plasma. All the parameters affecting the extraction efficiencies of both drugs were investigated and optimized. Under the optimal conditions, an effective analytes' preconcentration with enrichment factors (EFs) up to 72 was achieved. The linearity of the method was established over the concentration range of 0.50-70.0 and 3.0-100.0 ng/mL for venlafaxine and agomelatine, respectively with good correlation coefficients > 0.998. The method exhibited low detection limits in the range of 0.15-0.89 ng/mL and excellent precisions expressed in %RSD < 3% with average recoveries between 95.0 to 101.0%. The proposed method was employed to analyze the targeted analytes in dosage forms and human plasma samples with favorable characteristics like excellent enrichment, high sensitivity, great accuracy, and high precision. Finally, the greenness of the developed method was assessed using three distinct metric tools, confirming the greenness of the proposed method. The findings of this research could have more general implications for the extraction of other analytes from various matrices.

Abstract
AIMS Idiopathic pulmonary fibrosis (IPF) is a severe pulmonary interstitial pneumonia. Our study focuses on the role of PLA2 enzyme in the IPF to explore a more effective diagnosis and treatment mechanism of IPF. MAIN METHODS Transcriptome data of IPF from GEO database and bleomycin-induced pulmonary fibrosis mice were analyzed to identify PLA2 enzyme and their metabolite, lysophosphatidylcholines 18:0, in IPF. Based on PLA2G2A and PLA2G2D / PLA2G2A-associated cell death genes (PCDs), the consensus clustering analysis was used to identify the subtypes of IPF and the correlation between PLA2G2A and prognosis was analyzed. The machine learning (ML) models and artificial neural network (ANN) model was used to validate the diagnostic accuracy of PLA2s and PCDs in diagnosing IPF. The gene and protein expression of NLRP3, GSDMD, and CASP-1 was estimated in recombinant PLA2G2A protein induced MLE-12 cells. KEY FINDINGS The expression of PLA2G2D, PLA2G2A, and LPC18 significantly changed in IPF. Furtherly, PLA2G2A has a significant correlation with poor patient prognosis, which could predict the 2 or 3-years mortality rates of IPF. Two subtypes of IPF patients, identified based on PCDs, showed significant different immunoinfiltration. Recombinant PLA2G2A protein could induce the pyrotosis in the MLE-12 cell. The generalized linear model and ANN model of PLA2s or PCDs accurate diagnosis IPF. SIGNIFICANCE PLA2G2A is the most robustly associated gene with IPF among the PLA2s, which demonstrates a potential in diagnosing and prognostic value in IPF, and provides a foundation for further understanding and breakthroughs in IPF diagnosis and treatment.

Abstract
Loquat (Eriobotrya japonica) leaves contain many bioactive components such as ursolic acid (UA) and amygdalin. We investigated the effects of loquat leaf powder and methanol extract in human neuroglioma H4 cells stably expressing the Swedish-type APP695 (APPNL-H4 cells) and C57BL/6 J mice. Surprisingly, the extract greatly enhanced cellular amyloid-beta peptide (Aβ) 42 productions in APPNL-H4 cells. Administration of leaf powder increased Aβ42 levels after 3 months and decreased levels after 12 months compared to control mice. Leaf powder had no effect on working memory after 3 months, but improved working memory after 12 months. Administration of UA decreased Aβ42 and P-tau levels and improved working memory after 12 months, similar to the administration of leave powder for 12 months. Amygdalin enhanced cellular Aβ42 production in APPNL-H4 cells, which was the same as the extract. Three-month administration of amygdalin increased Aβ42 levels slightly but did not significantly increase them, which is similar to the trend observed with the administration of leaf powder for 3 months. UA was likely the main compound contained in loquat leaves responsible for the decrease in intracerebral Aβ42 and P-tau levels. Also, amygdalin might be one of the compounds responsible for the transiently increased intracerebral Aβ42 levels.

Abstract
A large variety of natural plants are widely produced and utilised because of their remarkable pharmacological effects. In this study, two phenolic glycosides were isolated for the first time from Vanilla pompona Schiede (Orchidaceae) from Kyushu, Japan: bis [4-(β-D - O-glucopyranosyloxy)-benzyl] (S)-2-isopropylmalate (1: ) and bis 4-[β-D-O-glucopyranosyloxy)-benzyl]-(2R,3S)-2-isopropyl tartrate (2: ). We have discovered that the crude extract of V. pompona leaves and stems and its two phenolic glycosides (compounds 1: - 2: ) are highly effective in reversing skin senescence. V. pompona and compounds 1: - 2: were found to promote the synthesis of collagen, hyaluronic acid, and elastin in skin fibroblasts in a normal skin cell model; in a replicative senescence model, V. pompona and compounds 1: - 2: significantly reduced the ageing phenotype in skin fibroblasts. These compounds also demonstrated a significant protective effect in a UV-induced photo-senescence model; the possible mechanisms of this effect were investigated in this study. To the best of our knowledge, this study is the first to develop V. pompona leaves and stems as new sources of bioactive compounds and to examine their therapeutic potential for skin senescence. The development potential of V. pompona leaves and stems for use in the cosmetics, cosmeceutical, and pharmaceutical industries remains to be investigated.

Abstract
Sixteen chemically varied metabolites were isolated from the bulbs of Hippeastrum vittatum (L'Her.) Herb., including eight flavonoids [3'-methyl isoliquiritigenin (2), 7-hydroxyflavan (8), 7-hydroxyflavanone (9), 7-hydroxyflavan-3-ol (10), 7-methoxy-3',4'-methylenedioxyflavan-3-ol (11), 7-hydroxy-3',4'-methylenedioxy flavan (12), 2',4'-dihydroxy-3'-methyl-3,4-methylenedioxychalcone (13), and isoliquiritigenin (14)], four acetophenones [2,6-dimethoxy-4-hydroxyacetophenone (3), 2,4-dihydroxyacetophenone (4), 2,4-dihydroxy-6-methoxy-3-methylacetophenone (6), and 2,4,6-trimethoxyacetophenone (7)], two alkaloids [lycorine (1) and narciprimine (15)], one phenol derivative [p-nitrophenol (5)], and one steroid [β-sitosterol 3-O-β-glucopyranoside (16)]. Their structures were elucidated by combining one- and two-dimensional NMR and ESI-MS techniques and by comparison with the reported literature data and some authentic samples. Except for lycorine (1), the isolated metabolites were obtained herein for the first time from Hippeastrum plants, among which compound 13 was identified as a new chalcone derivative. Additionally, the total phenolic and flavonoid contents of the total ethanol extract and different fractions of the bulbs were determined by the Folin-Ciocalteu and aluminum chloride colorimetric methods, respectively, whereas their antioxidant potential was compared using the phosphomolybdenum and 2,2'-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assays. Finally, the binding affinities of compounds 1-16 to some key target proteins of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), namely, main protease (Mpro), papain-like protease (PLpro), and RNA-dependent RNA polymerase (RdRp), were screened and compared using molecular docking analysis. The possible chemotaxonomic significance of the identified metabolites was also discussed.

Abstract
Oil spills that contaminate the environment can harm the surrounding ecosystem. The oil contains petroleum hydrocarbon which is toxic to the environment hence it needs to be removed. The use of bacteria as remediation media was modified by immobilizing into a matrix hence the bacteria can survive in harsh conditions. In this research, the ability of biosurfactant-producing bacteria (Pseudomonas aeruginosa, Bacillus subtilis, and Ralstonia pickettii) immobilized in the PVA/SA/bentonite matrix was tested in remediation on oil-contaminated soil. The immobilized beads filled with bacteria were added to the original soil sample, as well as washed soil. The beads were characterized by using FTIR and SEM. Based on FTIR analysis, the PVA/SA/bentonite@bacteria beads had similar functional groups compared to each other. SEM analysis showed that the beads had non-smooth structure, while the bacteria were spread outside and agglomerated. Furthermore, GC-MS analysis results showed that immobilized B. subtilis and R. pickettii completely degraded tetratriacontane and heneicosane, respectively. Meanwhile, after soil washing pre-treatment, immobilized bacteria could completely degrade octadecane (P. aeruginosa and R. pickettii) and tetratriacontane (P. aeruginosa and B. subtilis). Based on those results, immobilized bacteria could degrade oil compounds. The degradation result was influenced by the enzymes produced, the ability of the bacteria, the suitability of the test media, and the matrix used. Therefore, this study can be a reference for further soil remediation using eco-friendly methods.

Abstract
Juncus decipiens is a member of the Juncaceae family and has culinary, medicinal, and decorative properties. It is also used in traditional Chinese Medicines for many years that promotes diuresis for strangury and clears out heart fire. This species has recently gained medicinal attention as a source of phenanthrenes, phenolic compounds, glycerides, flavonoids, and cycloartane triterpenes. This plant was also shown to be active, and researchers explored its antioxidant, anti-inflammatory, antialgal, antibacterial, and psychological behaviour-boosting properties. Preliminary research suggests that this species might be used for skin protection and brain disorders if proper clinical trials are conducted. The ethnomedicinal, phytochemistry, biological potencies, dangers, and scopes of Juncus decipiens have been examined in this respect.

Abstract
Hericium erinaceus, a mushroom species commonly known as Yamabushitake in Japan, is known to have a stimulatory effect on neurotrophic factors, such as brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF). Hericenone C, a meroterpenoid with palmitic acid as the fatty acid side chain, is reported to be one such stimulant. However, according to the structure of the compound, the fatty acid side chain seems highly susceptible to lipase decomposition, under in vivo metabolic conditions. To study this phenomenon, hericenone C from the ethanol extract of the fruiting body was subjected to lipase enzyme treatment and observed for changes in the chemical structure. The compound formed after the lipase enzyme digestion was isolated and identified using LC-QTOF-MS combined with 1H-NMR analysis. It was found to be a derivative of hericenone C without its fatty acid side chain and was named deacylhericenone. Interestingly, a comparative investigation of the neuroprotective properties of hericenone C and deacylhericenone showed that the BDNF mRNA expression in human astrocytoma cells (1321N1) and the protection against H2O2-induced oxidative stress was considerably higher in the case of deacylhericenone. These findings suggest that the stronger bioactive form of the hericenone C compound is in fact deacylhericenone.

Abstract
The formation of the Ontong Java Nui super oceanic plateau (OJN), which is based on the model that the submarine Ontong Java Plateau (OJP), Manihiki Plateau (MP), and Hikurangi Plateau (HP) were once its contiguous fragments, could have been the largest globally consequential volcanic event in Earth's history. This OJN hypothesis has been debated given the paucity of evidence, for example, the differences in crustal thickness, the compositional gap between MP and OJP basalts and the apparent older age of both plateaus relative to HP remain unresolved. Here we investigate the geochemical and 40Ar-39Ar ages of dredged rocks recovered from the OJP's eastern margin. Volcanic rocks having compositions that match the low-Ti MP basalts are reported for the first time on the OJP and new ~ 96-116 Ma and 67-68 Ma 40Ar-39Ar age data bridge the temporal gap between OJP and HP. These results provide new evidence for the Ontong Java Nui hypothesis and a framework for an integrated tectonomagmatic evolution of the OJP, MP, and HP. The isotopic data imply four mantle components in the source of OJN that are also expressed in present-day Pacific hotspots sources, indicating origin from (and longevity of) the Pacific Large Low Shear-wave Velocity Province.

Abstract
BACKGROUND Alzheimer's disease (AD) is a neurodegenerative disease that is strongly associated with aging. Telomeres are DNA sequences that protect chromosomes from damage and shorten with age. Telomere-related genes (TRGs) may play a role in AD's pathogenesis. OBJECTIVES To identify TRGs related to aging clusters in AD patients, explore their immunological characteristics, and build a TRG-based prediction model for AD and AD subtypes. METHODS We analyzed the gene expression profiles of 97 AD samples from the GSE132903 dataset, using aging-related genes (ARGs) as clustering variables. We also assessed immune-cell infiltration in each cluster. We performed a weighted gene co-expression network analysis to identify cluster-specific differentially expressed TRGs. We compared four machine-learning models (random forest, generalized linear model [GLM], gradient boosting model, and support vector machine) for predicting AD and AD subtypes based on TRGs and validated TRGs by conducting an artificial neural network (ANN) analysis and a nomogram model. RESULTS We identified two aging clusters in AD patients with distinct immunological features: Cluster A had higher immune scores than Cluster B. Cluster A and the immune system are intimately associated, and this association could affect immunological function and result in AD via the digestive system. The GLM predicted AD and AD subtypes most accurately and was validated by the ANN analysis and nomogram model. CONCLUSION Our analyses revealed novel TRGs associated with aging clusters in AD patients and their immunological characteristics. We also developed a promising prediction model based on TRGs for assessing AD risk.

Abstract
Nutritional foods are concentrated sources of molecules with a nutritional or physiological effect which contain nutrients. There is a category, “nutricosmetics”, defined as ingestible natural health products that enhance the function and appearance of human skin, nails, and hair. A new variety of Flammulina velutipes (F. velutipes), Oki-Shirayuki 919, was explored to ascertain whether its components have functions of nutricosmetics. We focused on physiological effects for enhancing the human skin condition, such as moisturizing or barrier functions in F. velutipes. A randomized, double-blind, placebo-controlled clinical study was performed between January and March 2022. Among healthy men and women (n = 30) aged 20 to 59 years, the test group (n = 15) took a test product which included F. velutipes dry powder, and the placebo group (n = 15) took a placebo (a similar product in which the F. velutipes dry powder was replaced with plum fruit paste). Since the amount of increase in skin hydration over four weeks in the test group was significantly larger than that in the placebo group, a significant difference between the two groups was observed (p = 0.033). F. velutipe was suggested to have some physiological functions such as improving skin moisture.

Abstract
The timing of delivery and the types of body that contributed volatiles to the terrestrial planets remain highly debated1,2. For example, it is unknown if differentiated bodies, such as that responsible for the Moon-forming giant impact, could have delivered substantial volatiles3,4 or if smaller, undifferentiated objects were more probable vehicles of water delivery5-7. Here we show that the water contents of minerals in achondrite meteorites (mantles or crusts of differentiated planetesimals) from both the inner and outer portions of the early Solar System are ≤2 μg g-1 H2O. These are among the lowest values ever reported for extraterrestrial minerals. Our results demonstrate that differentiated planetesimals efficiently degassed before or during melting. This finding implies that substantial amounts of water could only have been delivered to Earth by means of unmelted material.

Abstract
Although considered an abundant source of agricultural by-products, avocado (Persea americana Mill.) seed, with several biological activities and bioactive components, might become a promising resource for phytopharmaceutical development. In this study, through bioassay-guided isolation of the main α-glucosidase inhibitors in avocado seed, we discovered the major α-glucosidase inhibitor to be avocado seed oligomeric proanthocyanidin complex (ASOPC). Thiolysis and UPLC-DAD-HRESIMS showed the presence of A- and B-type procyanidins, and B-type propelargonidin with (epi)afzelechin as extension unit. Mean degree of polymerization (mDP) of ASOPC was calculated as 7.3 ± 1. Furthermore, ASOPC appeared to be a strong, reversible, competitive inhibitor of α-glucosidase, with IC50 value of 0.1 µg/mL, which was significantly lower than Acarbose (IC50 = 75.6 µg/mL), indicated that ASOPC is a potential natural α-glucosidase inhibitor. These findings would contribute to the direction of utilizing avocado seed bioactive components with the possibility to be used as natural anti-diabetic agents.

Abstract
Since the recent coronavirus disease 2019 pandemic and the lifestyle changes it necessitated, the demand for mental health treatment has skyrocketed, with long wait lists for both psychological and psychiatric care. Over-the-counter supplements and home remedies are increasingly sought. In this study, we screened natural materials and blended supplements from Asia that may improve the mood and mental health of humans by testing cell viability and expression of the proopiomelanocortin gene as a marker of β-endorphin production in rat hypothalamus neuron cells. Among 23 tested samples, 3 samples produced significantly higher cell viability in R-HTH-507 cells than the control treatment. In a real-time-polymerase chain reaction (RT-PCR) experiment, 7 samples showed significant β-endorphin synthesis activity. This is the first report that the Asian natural materials Areca catechu, Moringa oleifera, Lignosis rhinocerus, and Aegle marmelos promote β-endorphin synthesis; further investigation will identify the active ingredients in the blended samples. These results suggested that these Asian natural materials have great potential to expand the range of treatments for mental health.

Abstract
We report a search for cosmic-ray boosted dark matter with protons using the 0.37 megaton×years data collected at Super-Kamiokande experiment during the 1996-2018 period (SKI-IV phase). We searched for an excess of proton recoils above the atmospheric neutrino background from the vicinity of the Galactic Center. No such excess is observed, and limits are calculated for two reference models of dark matter with either a constant interaction cross section or through a scalar mediator. This is the first experimental search for boosted dark matter with hadrons using directional information. The results present the most stringent limits on cosmic-ray boosted dark matter and exclude the dark matter-nucleon elastic scattering cross section between 10^{-33}cm^{2} and 10^{-27}cm^{2} for dark matter mass from 1 MeV/c^{2} to 300 MeV/c^{2}.

Abstract
Accumulating evidences show that the hazardous substance atmospheric nanoplastics increase the respiratory risk of individuals, but the inside toxicity mechanisms to lung tissue remain unclear. This study aims at investigating the potential mechanisms of inhaled cationic polystyrene nanoplastics (amine-polystyrene nanoplastics, APS-NPs)-induced pulmonary toxicity on mice. In vivo, the mice intratracheal administrated with APS-NPs suspension (5 mg/kg) were found inflammatory infiltrates in lung tissues through histopathology analysis. Furthermore, transcriptome analysis demonstrated that 1821 differentially expressed mRNA between APS group and control group were dominantly associated with 288 known KEGG pathways, indicating that APS-NPs might cause early inflammatory responses in lung tissue by activating the NLRP3/capase-1/IL-1β signaling pathway. Moreover, in vitro results also showed that NLRP3 inflammasome could be activated to induce pyroptosis in MLE-12 cells after exposure to APS-NPs. And, MH-S cells after exposure to APS-NPs exhibited increased Irg1 proteins, leading to the increasing generation of ROS and inflammatory factors (e.g., tnf-α, il-6, il-1β). In conclusion, these results revealed that Irg1/NF-κB/NLRP3/Caspase-1 signaling pathway was activated significantly after exposing to APS-NPs, leading to pulmonary toxicity on mice. Intriguingly, prior administration of the clinical antioxidant N-acetylcysteine (NAC) could serve as a possible candidate for the prevention and treatment of pulmonary toxicity induced by APS-NPs. The study contributes to a better understanding of the potential risks of environmental nanoplastics to humans and its improvement measure.

Abstract
We collected stingless bee propolis Tetragonula biroi in order to find materials for medicine and cosmetics applications from tropical rainforest resources. Even though this bee has some biological functions including a cancer cell line, hair growth promotion, asthma remedy, α-glucosidase enzyme inhibition, and antiviral action, the investigation on anti-acne has not been reported yet. This study was to focus on propolis Tetragonula biroi extracts and leads us to isolate active compounds for antioxidant, anti-inflammatory, and anti-acne. We used methanol to obtain the extract from this propolis and assayed it with antioxidants, anti-inflammation, and anti-acne. The extract showed strong activity in antioxidants by DPPH radical scavenging activity (82.31% in 6.25 μg/ml). Via a column chromatography and Reveleris PREP purification system, we isolated 3'-O-methyldiplacone, nymphaeol A, and 5,7,3',4'-tetrahydroxy-6-geranyl flavonol. These compounds showed potential biological activity with IC50 for antioxidant 6.33, 15.49, 17.32 μM; and antiinflammatory 121.54, 121.20, 117.31 μM. The isolated compounds showed anti-acne properties with properties 0.00, 14.11, and 13.78 mm for the inhibition zone (at a concentration of 1 μg/well), respectively. The results indicated that the propolis extract of Tetragonula biroi has the potential to be developed as a cosmetic agent; however, further work needs to be done to clarify its application.

Abstract
New ternary deep eutectic solvents were prepared and applied as efficient green dispersing solvents in miniaturized matrix solid-phase dispersion to extract chlorophenols from river sediments for the first time. High-performance liquid chromatography coupled with a photodiode array detector was used to analyze the target analytes. The significant factors affecting the extraction were optimized as follows: dispersant (100 mg), sample (100 mg), ternary eutectic solvents (150 μl), grinding for 1 min, 450 μl of acetonitrile as the elution solvent, and vortex mixing for 20 s. Under the optimal conditions, the method exhibited excellent linearity (correlation coefficient > 0.9980), low limits of detection between 1.039-2.478 μg/g, and extraction recoveries between 93.9% and 99.2%. Furthermore, the method demonstrated excellent precision in the intra- and inter-day analysis with a relative standard deviation below 6%. When compared to conventional extraction techniques, the miniaturized matrix solid-phase dispersion considerably reduced samples and solvent usag, offering important environmental benefits. The green profile of the method was assessed using the complementary green analytical procedure index tool confirming its eco-friendship. The technique was finally employed to evaluate sediment samples from three distinct locations along the Zuibaiji River, indicating its applicability for monitoring environmental samples.

Abstract
This study targets the evaluation of melanin synthesis inhibition activity of the bamboo shoot skin as agro-waste. The total methanolic extract of bamboo peel extract was evaluated for its skin protective effects via measuring its melanin inhibitory activity and its suppression activity on the expression of tyrosinase mRNA levels. Results showed that bamboo peel extract has a good ability for the inhibition of melanin synthesis so further studies were performed for the isolation of its constituents. Twelve compounds have been isolated from the shoot skin of Phyllostachys pubescens. Their structures were elucidated based on extensive spectroscopic methods. The melanin inhibition potential of the isolates was tested with their collagen-production-promoting activity for the determination of active principles. Results showed that Betulinic acid, tachioside, and 1,2-dilinolenin significantly suppressed melanin production per cell compared to control. Triacontanol, tricin, and (+)-lyoniresinol 9'-O-glucoside also tended to decrease melanin production per cell. These findings indicated that the skin of bamboo shoots, a significant agricultural waste, is a useful natural source for further research on its potential for aging problems such hyperpigmentation and cognitive function impairment.

Abstract
Hyperpigmentation is a skin condition where patches of skin become darker in color due to excess melanin production upon UV exposure leading to melasma, which are lentigines or post inflammatory hyperpigmentation that psychologically affecting a great number of people. The present study investigates the anti-melanogenic effect of Butyroside D and the underling mechanism. After the confirmation of the non-cytotoxic effect of Butyroside D on B16F10 cells, we proceeded with analyzing the impact of the treatment at low and high concentration (i.e., 0.2 μM and 2 μM) using gene profiling analysis and examined the differentiation in gene expression. Our results identify cyclic adenosine monophosphate (cAMP), Wnt/β-catenin and Mitogen-Activated Protein Kinase (MAPK) signaling pathways to be downregulated upon treatment with Butyroside D. These pathways were targeted to further validate the effect of Butyroside D on membrane receptors melanocortin 1 receptor (MC1R) and receptor tyrosine kinase (c-Kit), related microphthalmia-associated transcription factor (MITF) and consequently tyrosinase (TYR), and tyrosine-related protein-1 (TYRP-1) that were all shown to be downregulated and, therefore, leading to the repression of melanin biosynthesis. Finally, the anti-melanogenic effect of Butyroside D was confirmed on human epidermal melanocytes (HEM) cells by inhibiting the activation of cAMP pathway generally mediated through α-melanocyte-stimulating hormone (α-MSH) and MC1R. Overall, this study suggests the potential applicability of this purified compound for the prevention of hyperpigmentation conditions.

Abstract
Diet is considered as a major driver of gut microbiota composition. However, little is known about the relationship between overall dietary balance and gut microbiota, especially in the elderly. Here, using the Quantitative Index for Dietary Diversity (QUANTIDD), we analysed the relationships between dietary diversity and gut microbiota diversity in 445 Japanese subjects aged 65-90 years. We also examined the effect of age by comparing the young-old group aged 65 to 74 years (<75 years group; n=246) and the old-old group aged 75 years and older (≥75 years group; n=199). QUANTIDD showed significant positive relationships with Pielou's evenness and Shannon indices, two α-diversity indices related to the uniformity of species distribution. This suggests that a more diverse diet is associated with a more uniform abundance of various bacterial groups, rather than a greater variety of gut bacteria. QUANTIDD also showed significant positive associations with the abundance of Anaerostipes, Eubacterium eligens group, and Eubacterium ventriosum group, which produce short-chain fatty acids (SCFAs) and are beneficial to health. Negative association was found with the abundance of Ruminococcus gnavus group, which produces inflammatory polysaccharides. Positive associations between QUANTIDD and α-diversity indices or the abundance of specific bacterial groups were identified among all subjects and in the <75 years group, but not in the ≥75 years group. Our results suggest that dietary diversity contributes to the diversity of the gut microbiota and increases the abundance of SCFAs-producing bacteria, but only up to a certain age. These findings help to understand the complex relationship between diet and gut microbiota, and provide hints for specific dietary interventions to promote beneficial gut microbiota in the elderly.

Abstract
Bassia indica (Wight) A.J. Scott, family Amaranthaceae, is a halophyte herb growing in extreme environments and hence deemed as a potential economic source of bioactive chemicals with functional properties. In our study, 25 compounds were obtained from B. indica. We aimed to assess the inhibitory effect of the methanol extract of B. indica and its isolated compounds on COX-2 and cytotoxicity activity against MCF-7, OVK-18, HepG2, and HCT116 tumor cells. Among the isolates, the triterpene oleanane saponin (23) displayed promising anti-inflammatory activity with an IC50 = 3.05 ± 0.15 μg/mL. Additionally, N- trans-feruloyl tyramine (11) exhibited significant cytotoxicity to OVK-18 with IC50 = 1.74 ± 1.56 μg/mL, whereas 6,7-dihydroxy coumarin (7) exhibited potent inhibition against the MCF-7 cell line with IC50 = 1.47 ± 0.22 μg/mL. Interestingly, compounds 1 and 25 exhibited remarkable cytotoxicity against HepG2 and HCT116 cells with IC50 < 0.1 μg/mL, while compounds 2, 4, 5, 6, and 9 exerted potent cytotoxicity against HepG2. Finally, B. indica is a potential source of candidate compounds for the development of anti-inflammatory and antitumor therapies.

Abstract
Chemical investigation of the total extract of the Egyptian soft coral Heteroxenia fuscescens, led to the isolation of eight compounds, including two new metabolites, sesquiterpene fusceterpene A (1) and a sterol fuscesterol A (4), along with six known compounds. The structures of 1–8 were elucidated via intensive studies of their 1D, 2D-NMR, and HR-MS analyses, as well as a comparison of their spectral data with those mentioned in the literature. Subsequent comprehensive in-silico-based investigations against almost all viral proteins, including those of the new variants, e.g., Omicron, revealed the most probable target for these isolated compounds, which was found to be Mpro. Additionally, the dynamic modes of interaction of the putatively active compounds were highlighted, depending on 50-ns-long MDS. In conclusion, the structural information provided in the current investigation highlights the antiviral potential of H. fuscescens metabolites with 3β,5α,6β-trihydroxy steroids with different nuclei against SARS-CoV-2, including newly widespread variants.

Abstract
The broader objective of this study is to identify natural materials that might inhibit the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We have focused on stingless bee honey, which has a unique taste that is both sweet and sour and sometimes bitter. We screened 12 samples of honey from 11 species of stingless bees using an angiotensin-converting enzyme 2 (ACE2)-spike protein-binding assay and phytochemical analysis. Ten of the samples showed inhibition above 50% in this assay system. Most of the honey contained tannins, alkaloids, flavonoids, triterpenoids, carotenoids and carbohydrates. Our findings in this in vitro study showed that honey from stingless bees may have a potent effect against SARS-CoV-2 infection by inhibiting the ACE2-spike protein-binding.

Abstract
The phytochemical study of Agathophora alopecuroides (Chenopodiaceae) led to the isolation of previously undescribed glucosylceramide, flavonol triglycoside, and triterpene oleanane saponin, together with eight known compounds. Their structures were elucidated using NMR analysis and HR-MS as (2'R, 12E) N-[(2S, 3S, 4R)-1-(β-D-glucopyranosyloxy)-3,4-dihydroxy-octadec-2-yl]-2-hydroxytetracos-12-enamide, namely Agathophamide A; isorhamnetin-3-O-[β-D-xylopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→6)]-β-D-galactopyranoside, namely Agathophoroside A; and 3-O-[4'-(β-D-xylopyranosyl)-β-D-glucuronopyranosyl]-28-O-β-D-glucopyranosyl-olean-12-en-3β-ol-28-oic acid, namely Solysaponin A. We evaluated the effect of extract and isolates on ceramide levels via the up-regulated expression of the enzyme for ceramide synthesis in HaCaT keratinocytes. Interestingly, the study results revealed that the methanol extract of A. alopecuroides, together with some isolated compounds significantly up-regulated the mRNA expression of ceramide synthase-3 by 1.2- to 4.3-fold compared with the control in HaCaT cells. These findings indicate that the halophyte A. alopecuroides is a promising source of candidate compounds that can contribute to ceramide synthesis via the up-regulated expression levels of ceramide synthase-3 in the ceramide synthesis pathway.

Abstract
Shiikuwasha (Citrus depressa Hayata) essential oil (SEO) extracted from Shiikuwasha fruit pulp contains two major volatile components, limonene and γ-terpinene (56.56–57.31 and 24.41–24.98%, respectively). In this study, we showed that the aroma streams of SEO, limonene, and γ-terpinene exhibited significant physiological stress amelioration effects in nine healthy female panelists tested in a 30-min visual display task. While SEO administration significantly reduced work errors by 15 min compared to the odorless control condition, the limonene stream reduced work errors only at the first and fourth 5-min intervals, and the γ-terpinene effect lasted only for the initial 5-min. However, γ-terpinene inhalation reduced stress by significantly increasing post-work electrocardiogram R–R interval variability and lowering electroencephalogram beta wave powers at the midline occipital Oz position. Additionally, SEO, limonene, and γ-terpinene displayed anti-inflammatory activity in vitro by suppressing the pro-inflammatory markers NO and IL-1β in BV-2 microglial cells in a dose-dependent manner.

Abstract
Averrhoa carambola L. is reported for its anti-obese and anti-diabetic activities. The present study aimed to investigate its aqueous methanol leaf extract (CLL) in vivo anti-obese activity along with the isolation and identification of bioactive compounds and their in vitro α-glucosidase inhibition assessment. CLL improved all obesity complications and exhibited significant activity in an obese rat model. Fourteen compounds, including four flavone glycosides (1–4) and ten dihydrochalcone glycosides (5–12), were isolated and identified using spectroscopic techniques. New compounds identified in planta included (1) apigenin 6-C-(2-deoxy-β-D-galactopyranoside)-7-O-β-D-quinovopyranoside, (8) phloretin 3′-C-(2-O-(E)-cinnamoyl-3-O-β-D-fucopyranosyl-4-O-acetyl)-β-D-fucopyranosyl-6′-O-β-D fucopyranosyl-(1/2)-α-L arabinofuranoside, (11a) phloretin3′-C-(2-O-(E)-p-coumaroyl-3-O-β-D-fucosyl-4-O-acetyl)-β-D-fucosyl-6′-O-(2-O-β-D-fucosyl)-α-L-arabinofuranoside, (11b) phloretin3′-C-(2-O-(Z)-p-coumaroyl-3-O-β-D-fucosyl-4-O-acetyl)-β-D-fucosyl-6′-O-(2-O-β-D-fucosyl)-α-L-arabinofuranoside. Carambolaside M (5), carambolaside Ia (6), carambolaside J (7), carambolaside I (9), carambolaside P (10a), carambolaside O (10b), and carambolaside Q (12), which are reported for the first time from A. carambola L. leaves, whereas luteolin 6-C-α-L-rhamnopyranosyl-(1-2)-β-D-fucopyranoside (2), apigenin 6-C-β-D-galactopyranoside (3), and apigenin 6-C-α-L-rhamnopyranosyl-(1-2)-β-L-fucopyranoside (4) are isolated for the first time from Family. Oxalidaceae. In vitro α-glucosidase inhibitory activity revealed the potential efficacy of flavone glycosides, viz., 1, 2, 3, and 4 as antidiabetic agents. In contrast, dihydrochalcone glycosides (5–11) showed weak activity, except for compound 12, which showed relatively strong activity.

Abstract
In Alzheimer's disease (AD), the accumulation of amyloid-β plaques, overactivity of MAO-B, and phosphorylated tau protein in the central nervous system result in neuroinflammation and cognitive impairments. Therefore, the multi-targeting of these therapeutic targets has emerged as a promising strategy for the development of AD treatments. The current study reports the isolation and identification of seven amide alkaloids, namely, N-trans-feruloyl-3-methoxytyramine (1), N-trans-feruloyltyramine (2), S-(-)-N-trans-feruloylnormetanephrine (3), S-(-)-N-trans-feruloyloctopamine (4), R-(+)-N-trans-feruloyloctopamine (5), N-trans-caffeoyltyramine (6), and S-(-)-3-(4-hydroxy-3-methoxyphenyl)-N-[2-(4-hydroxyphenyl)-methoxyethyl]acrylamide (7), from B. indica and A. alopecuroides, which are halophytic plants that have been reported to contain diverse phytochemicals. Additionally, the study explores the potential inhibition effects of the isolates on β-secretase, monoamine oxidase enzymes, and phosphorylated tau protein, and their anti-aggregation effects on amyloid-β fibrils. Compounds 1, 2, and 7 showed potent inhibitory activity against BACE1, MAO-B, and phosphorylated tau protein, as well as anti-aggregation activity against Aβ-peptides. Additionally, compound 6 displayed promising inhibition activity against MAO-B enzyme. Further in-depth in silico and modeling analyses (i.e., docking, absolute binding free energy calculations, and molecular dynamics simulations) were carried out to reveal the binding mode of each active compound inside the corresponding enzyme (i.e., MAO-B and BACE1). The results indicate that B. indica, A. alopecuroides, and the isolated amide alkaloids might be useful in the development of lead compounds for the prevention of neurodegenerative diseases, especially AD.

Abstract
OBJECTIVES We previously reported, based on a multicenter randomized-control study, that the efficacy of intra-articular injections of hyaluronic acid (IA-HA) was not inferior to that of oral non-steroidal anti-inflammatory drugs (NSAIDs) in patients with knee osteoarthritis (OA). However, the molecular effects on the pathophysiology of knee OA remain unclear. C-terminal telopeptides of type II collagen (CTX-II) is reported to primarily originate from the interface between articular cartilage and subchondral bone, which is a site of potential remodeling in OA. We performed a predefined sub-analysis of the previous study to compare the changes of urinary CTX-II (uCTX-II) in response to IA-HA to those in response to NSAID for knee OA. DESIGN A total of 200 knee OA patients were registered from 20 hospitals and randomized to receive IA-HA (2,700 kDa HA, 5 times at 1-week intervals) or NSAID (loxoprofen sodium, 180 mg/day) for 5 weeks. The uCTX-II levels were measured before and after treatment. RESULTS The uCTX-II levels were significantly increased by IA-HA treatment (337.7 ± 193.8 to 370.7 ± 234.8 ng/μmol Cr) and were significantly reduced by NSAID treatment (423.2 ± 257.6 to 370.3 ± 250.9 ng/μmol Cr). The %changes of uCTX-II induced by IA-HA (11.6 ± 29.5%) and NSAID (-9.0 ± 26.7%) was significantly different (between-group difference: 20.6, 95% confidence intervals: 10.6 to 30.6). CONCLUSIONS While both IA-HA and NSAID improved symptoms of knee OA, uCTX-II levels were increased by IA-HA and reduced by NSAIDs treatment, suggesting these treatments may improve symptoms of knee OA through different modes of action.

Abstract
Chronic ultraviolet (UV) exposure produces oxidative stress, molecular damage, and aging-related signal transduction, all of which contribute to skin photoaging. In this study, the antioxidant and anti-inflammatory activities of Entada phaseoloides are reported. High-performance liquid chromatography (HPLC) detected 7 phenolic compounds: gallic acid, protocatechuic acid, 4-hydroxybenzoic acid, quercetin, luteolin, kaempferol, and apigenin. We investigated the antioxidant and protective effect of the acetone extract of E. phaseoloides leaves (AEP) on UVB-irradiated human epidermal keratinocytes (HaCaT cells). AEP showed antioxidant activity in the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) assays. AEP at a concentration of 40 μg/mL increased cell survival rate of the UVB-damaged cells. Moreover, AEP blocked gene expression of nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in UVB-induced HaCaT cells and decreased UVB-induced apoptosis in HaCaT cells by regulating the gene expression of caspase-3. These results suggest that AEP has the potential to protect against UVB irradiation and antioxidant.

Abstract
Pulmonary fibrosis (PF) is a chronic interstitial lung disease with unknown etiology. In the present study, we evaluated the anti-fibrotic effects of heterophyllin B, a natural product from Radix Pseudostellariae having anti-inflammatory and tyrosinase inhibitory activities. In bleomycin (BLM)-induced PF mouse model, heterophyllin B treatments (5 or 20 mg/kg/d) significantly attenuated BLM-induced alveolar cavity collapse, inflammatory cell infiltration, alveolar wall thickening and collagen deposition. When compared to model group, heterophyllin B treatments also increased adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) phosphorylation levels by 359% (P < 0.001) and reduced the expression of stimulator of interferon genes (STING) by 73% (P < 0.001). Furthermore, co-administration of heterophyllin B with AMPK inhibitor dorsomorphin (Compound C) significantly blocked the improvement effects of heterophyllin B on BLM-damaged lung tissue, and also increased the protein expression of STING which was inhibited by heterophyllin B in fibrotic lungs (P < 0.001). It is known that alveolar epithelia and lung fibroblasts exert prominent roles in the fibrosis progression. In the present study we found that, in vitro, heterophyllin B significantly inhibited alveolar epithelial mesenchymal transition (EMT) and lung fibroblast transdifferentiation. We also found that the inhibition of heterophyllin B on lung fibroblast transdifferentiation and STING expression was reversed by Compound C. To summarize, heterophyllin B exhibited protective effects on BLM-induced lung fibrosis potentially by inhibiting TGF-Smad2/3 signalings and AMPK-mediated STING signalings.

Abstract
Introduction Placenta extract is used as an ingredient in ointments for treating dermatological diseases, skin dryness, and for skin beautification. However, the clinical effects of the equine placenta on humans and the underlying mechanism of action are unclear. This randomized, controlled, double‐blind study aimed to clinically evaluate the effect of oral intake of equine placental extract on human skin quality. Methods Healthy women volunteers between the ages of 30 and 59 years (n = 29) were randomly assigned to receive 220 mg of equine placental extract–placebo orally, once daily for 4 weeks. Skin quality parameters such as skin hydration, skin barrier function (transepidermal water loss [TEWL]), and melanin index were assessed at baseline and after 4 weeks of administration. Results The melanin index was significantly increased in the placebo group, whereas it remained unchanged in the equine placenta group. The pattern of melanin index change was significantly different due to intake or no intake of equine placenta supplements over 4 weeks. No significant difference was found in skin hydration and TEWL between the two groups at 4 weeks of postadministration. It was shown that the intake of the equine placenta was more effective in protecting the skin condition against the change of ultraviolet (UV) sensitively than the change in temperature and humidity. Conclusions Effect of equine placental extract intake was evident on the cheek skin of the equine placenta group where participants were protected from UV‐induced pigmentation. Equine placental extract is useful for decreasing melanin synthesis and melanin content in the human skin and can be used as an effective food supplement to maintain human skin quality.

Abstract
This study compared the participants’ physiological responses and subjective evaluations of air scented with different concentrations of common rush (Juncus effusus L. var. decipiens Buchen.) (30 g and 15 g, with fresh air as a control). We asked 20 participants to complete a series of visual discrimination tasks while inhaling two different air samples. We evaluated (1) brain activity, (2) autonomic nervous activity, and (3) blood pressure and pulse rate, (4) in combination with self-evaluation. In addition, we quantified the concentrations of volatile organic compounds. The participants reported the scent to be sour, pungent, and smelly; this impression was likely caused by hexanal and acetic acid. Although the self-evaluations showed that participants did not enjoy the scent, their alpha amplitudes of electroencephalogram and parasympathetic nervous activity were increased, suggesting that participants were relaxed in this atmosphere. Moreover, a lower concentration resulted in a greater induction of relaxation. While the air was not pleasant-smelling, the volatile organic compounds present had a positive psychophysiological impact.

Abstract
BACKGROUND Bryodulcosigenin (BDG) a cucurbitane-type triterpenoid has been isolated from the roots of Bryonia dioca and possesses marked anti-inflammatory effects, although its beneficial effect against intestinal disorders remains unclear. PURPOSE To explore the underlying mechanism of BDG on the dysbiosis of chronic ulcerative colitis (UC) and its associated side-effects on lung tissues. METHODS A chronic UC model was established using 2.5% dextran sulfate sodium (DSS) in mice treated for 64 days and diagnostic assessments, western blot analysis and quantitative real time-PCR were employed to determine the protective mechanism of BDG. RESULTS Oral administration of BDG (10 mg/kg/day) significantly improved colon length, disease activity index, and alleviated colonic histopathological damage in the DSS-induced colitis mice. BDG not only reversed the TNF-α-induced degradation of tight junction proteins (occludin and ZO-1) but also suppressed the elevated apoptosis seen in intestinal epithelial cells (NCM460). In addition, BDG significantly attenuated damage in alveolar epithelial cells (MLE-12) co-cultured with NCM460 cells under inflammatory conditions. Furthermore, BDG in vivo significantly prevented the symptoms of respiratory disorders and repressed alveolar inflammation by regulating DSS-induced chronic colitis in mice. CONCLUSION BDG effectively inhibited the apoptosis of intestinal epithelial cells and suppressed the activation of the NLRP3 inflammasome which resulted in the restoration of the intestinal barrier. Therefore, the enhanced integrity of intestinal epithelial cells produced by BDG intervention contributed to its anti-colitis effects, indicating its great potential as an inhibitor of UC and lung injury. Therefore, restoring intestinal integrity may represent a promising strategy in the prevention of pulmonary disease.
