Megjegyzések:The anthocyanin content of Hungarian sour cherry is remarkable based on our preliminary investigations. Nutraceutical and pharmaceutical effects of anthocyanins has been extensively studied. The objective of the this work was investigation of pure sour cherry extract using human umbilical cord vein endothelial cells (HUVECs) as inflammatory model. Endothelial cells are involved in the pathogenesis of a number of inflammatory diseases, express various inflammatory mediators including cytokines, chemokines and reactive oxygen species. HUVECs were isolated by enzymatic digestion, characterized by flow cytometry and treated 100 ng/ml lipopolysaccharide (LPS) and sour cherry extract of different concentrations or M199 medium as control. The optimal concentration range of sour cherry extract was investigated and selected based on MTT, apoptosis and necrosis assays. The effect of sour cherry extract on oxidative stress was investigated by glutathione assay and measurement of level of reactive oxygen radicals (ROS) was performed. Pro-inflammatory factors were evaluated by Luminex MagPlex technique. Arachidonic pathway was tested by Q-PCR. The extract under investigation seems to have a pleitropic effect including anti-oxidative, anti-inflammatory, haemostatic, vasoactive effect. Our results indicate pure sour cherry extract could reduce the LPS-induced inflammatory thereby improving endothelial dysfunction

Megjegyzések:A Hungarian survey of Tokaj-Mád vineyards was conducted. Shotgun metabarcoding was applied to decipher the microbial-terroir. The results of 60 soil samples showed that there were three dominant fungal phyla, Ascomycota 66.36% - 15.26%, Basidiomycota 18.78% - 14.90%, Mucoromycota 11.89% - 8.99%, representing 97% of operational taxonomic units (OTUs). Mutual interactions between microbiota diversity and soil physicochemical parameters were revealed. Principal component analysis showed descriptive clustering patterns of microbial taxonomy and resistance gene profiles in the case of the four historic vineyards (Szent Tama? s, Kira? ly, Betsek, Nyu? la?szo? ). Linear discriminant analysis effect size was performed, revealing pronounced shifts in community taxonomy based on soil physicochemical properties. Twelve clades exhibited the most significant shifts (LDA > 4.0), including the phyla Verrucomicrobia, Bacteroidetes, Chloroflexi, and Rokubacteria, the classes Acidobacteria, Deltaproteobacteria, Gemmatimonadetes, and Betaproteobacteria, the order Sphingomonadales, Hypomicrobiales, as well as the family Sphingomonadaceae and the genus Sphingomonas. Three out of the four historic vineyards exhibited the highest occurrences of the bacterial genus Bradyrhizobium, known for its positive influence on plant development and physiology through the secretion of steroid phytohormones. During ripening, the taxonomical composition of the soil fungal microbiota clustered into distinct groups depending on altitude, differences that were not reflected in bacteriomes. Network analyses were performed to unravel changes in fungal interactiomes when comparing postveraison and preharvest samples. In addition to the arbuscular mycorrhiza Glomeraceae, the families Mycosphaerellacae and Rhyzopodaceae and the class Agaricomycetes were found to have important roles in maintaining soil microbial community resilience. Functional metagenomics showed that the soil Na content stimulated several of the microbiota-related agrobiogeochemical cycles, such as nitrogen and sulphur metabolism; steroid, bisphenol, toluene, dioxin and atrazine degradation and the synthesis of folate.

Megjegyzések:Increased permeability of the epithelial and endothelial cell layers results in the onset of pathogenic mechanisms. In both cell types, cell?cell connections play a regulatory role in altering membrane permeability. The aim of this study was to investigate the modulating effect of anthocyanin-rich extract (AC) on TJ proteins in inflammatory Caco-2 and HUVEC monolayers. Distribution of Occludin and zonula occludens-1 (ZO-1) were investigated by immunohistochemical staining and the protein levels were measured by flow cytometry. The mRNA expression was determined by quantitative real-time PCR. The transepithelial electrical resistance (TEER) values were measured during a permeability assay on HUVEC cell culture. As a result of inflammatory induction by TNF-?, redistribution of proteins was observed in Caco-2 cell culture, which was reduced by AC treatment. In HUVEC cell culture, the decrease in protein and mRNA expression was more dominant during inflammatory induction, which was compensated for by the AC treatment. Overall, AC positively affected the expression of the examined cell-binding structures forming the membrane on both cell types

Cím:Determination of Flavonoid and Proanthocyanidin Profile of Hungarian Sour Cherry / Nemes Andrea, Szőllősi Erzsébet, Stündl László, Biró Attila, Homoki Judit, Szarvas Mária, Balogh Péter, Cziáky Zoltán, Remenyik Judit

Megjegyzések:Hungarian sour cherries (SC) are excellent source of anthocyanin (concentrations (100?300 mg in 100 g fresh fruit) and melatonin (0.15 mg in 100 g fresh fruit), but other flavonoid derivatives also can be isolated by aqueous alcoholic extraction. We have developed a new process for extracting non-extractable procyanidines bound to the membrane, proteins, and fibers. These compounds were seperated with UHPLC-MS methods, and the structure of individual components were identified on the basis of their mass fragmentation spectra. The antioxidant capacity of soluble and non-soluble antioxidants were measured with ferric reducing antioxidant power (FRAP), 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity (DPPH), trolox equivalent antioxidant capacity (TEAC) assays, and compared to the new measurement methods of water-soluble antioxidant capacity (ACW), lipid-soluble antioxidant capacity (ACL). Furthermore, total phenolic content (TPC) and total procyanidin content (PAC) were determinated. As a result of our investigation, we found that the solvent combination, where in the first step is water?ethanol (1:1), then 100% ethanol were suitable for the extraction of the extractable antioxidants. However, the chemiluminescence method that is based on the elimination of the superoxide radical is more accurate than other colorimetric methods which measure antioxidant capacity.

Cím:HPLC Analysis of Polyphenols Derived from Hungarian Aszú from Tokaj Wine Region and Its Effect on Inflammation in an In Vitro Model System of Endothelial Cells / Arnold Markovics, László Csige, Erzsébet Szőllősi, Hajnalka Matyi, Andrea Diána Lukács, Nóra Réka Perez, Zsófia Réka Bacsó, László Stündl, Judit Remenyik, Attila Biró

Megjegyzések:Many studies have been published in recent years regarding the fact that moderate wine consumption, as a part of a balanced diet can have a beneficial effect on human health. The bio- logically active components of wine continue to be the subject of intense research today. In this study, the bioactive molecules of Hungarian aszú from the Tokaj wine region were analyzed using high-performance liquid chromatography (HPLC) and investigated in an in vitro model system of endothelial cells induced by bacterial-derived lipopolysaccharide. The HPLC measurements were performed on a reversed phased column with gradient elution. The non-cytotoxic concentration of the active substance was determined based on 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyltetrazolium bromide (MTT)-, apoptosis, and necrosis assays. The antioxidant effect of the extract was determined by evaluating its ability to eliminate ROS. The expressions of the interleukin-(IL)1?, IL1-?, IL-6, and IL-8 pro-inflammatory cytokines and nitric oxide synthase (eNOS) at the mRNA level were evaluated using a quantitative polymerase chain reaction (qPCR). We found that the lipopolysaccharides (LPS)- induced increases in the expressions of the investigated cytokines were significantly suppressed by Hungarian aszú extract, excluding IL-6. In our experimental setup, our treatment had a positive effect on the eNOS expression, which was impaired as a result of the inflammatory manipulation. In our experimental model, the Hungarian aszú extract decreased the LPS-induced increases in the expression of the investigated cytokines and eNOS at the mRNA level, which presumably had a positive effect on the endothelial dysfunction caused by inflammation due to its strong antioxidant and anti-inflammatory effects. Collectively, this research contributes to a more thorough understanding of the bioactive molecules of aszú from the Tokaj wine region.

Cím:Deciphering the Role of Postbiotics Derived from Bacillus subtilis natto on LPS-Induced Endothelial Cell Dysfunction / Szendi Róbert, Szilágyi Endre, Szarvas Mária Magdolna, Kovács-Forgács Ildikó, Homoki Judit Rita, Pesti-Asbóth Georgina, Szőllősi Erzsébet, Fazekas Mónika Éva, Cziáky Zoltán, Lukács János, Stündl László, Szilágyi-Tolnai Emese, Remenyik Judit

Megjegyzések:Background: This study aimed to assess the effects of postbiotic derived from Bacillus subtilis natto (Szendi2020) on endothelial responses under LPS-induced inflammatory stress. Methods: In human umbilical vein endothelial cells (HUVECs), inflammation was induced with 200 ng/mL LPS. Cell viability, apoptosis, and mitochondrial integrity were assessed using MTT assay, DiIC, and Sytox Green permeability assays. Intracellular ROS levels, heat shock proteins (HSPB1/Hsp27, HSPA1L/Hsp70), adhesion molecules (ICAM-1, VCAM-1), tight junction protein (Occludin), transcription regulators (NF-?B, TNF?), and proinflammatory cytokines (IL-1?, IL-6, IL-8) were quantified using qPCR and ELISA. Results: LPS exposure significantly induced apoptosis in HUVECs, as reflected by decreased metabolic activity, decreased mitochondrial membrane potential, and increased cell death (p < 0.05). Concurrent postbiotic administration completely abolished LPS-induced cytotoxicity in all assay platforms, demonstrating a potent cytoprotective effect. Postbiotic treatment significantly reduced LPS-induced ROS accumulation (p < 0.05). LPS significantly increased Hsp27 and Hsp70 mRNA expression. However, combined LPS and postbiotic exposure mitigated Hsp27 and Hsp70 mRNA expression compared with LPS treatment alone (p < 0.001, p < 0.005). Postbiotic treatment also decreased the upregulation of adhesion molecules induced by LPS. Although this effect decreased after 24 h (p < 0.001). LPS strongly increased NF-?B, IL-1? and TNF? mRNA levels and was suppressed by postbiotics at early time points but not maintained over 24 h. Importantly, postbiotics significantly reduced IL-6, and IL-8 expression at both the mRNA and protein levels, highlighting the attenuation of endothelial inflammatory features (p < 0.05, p < 0.005, p < 0.001). Conclusions: Our results are the first to demonstrate that postbiotics derived from Bacillus subtilis natto (Szendi2020) exert potent cytoprotective and anti-inflammatory effects in LPS-induced endothelial inflammation. By reducing ROS accumulation, preventing apoptosis, stabilizing mitochondrial and barrier integrity, modulating HSP, NF-?B, and cytokine responses. Postbiotics may be promising therapeutic candidates for alleviating endothelial inflammation and the resulting endothelial dysfunction.
