Melatonin has a powerful antioxidant ability and can enhance the effect of stem cells. Objectives This work aimed to investigate the melatonin’s effect on oxidative stress of differentiated adipose-mesenchymal stem cells (AD-MSCs) to dopaminergic (DAergic) cells. Material and methods The AD-MSCs cells were characterized after passage 3 by flow cytometry method and divided into four groups: (a) control group that was nontreated AD-MSCs, (b) MSCs+M group that was AD-MSCs cultured with 1 μM melatonin in expansion media for 12 days, (c) DN group that was MSCs treated with neurobasal A media for 12 days, (d) DN+M group which was MSCs cultured with 1 μM melatonin and neurobasal A media for 12 days. After 12 days, the catalase (CAT) activity and malondialdehyde (MDA) level were measured by using ELISA. Also, the gene expression level of MAP-2 was detected. Results and conclusion The current study proved that the isolated cells were MSCs due to high expression percentages for CD73 and CD90 and low expression percentages for CD34 and CD45. The DN+M group showed the highest expression of MAP-2 gene when compared to the other different groups (P ≤ 0.05). Moreover, there was a significant increase in CAT concentration in groups treated with melatonin than other group (P ≤ 0.05), while, there was no change in MDA level between all groups. It was concluded that melatonin has an effective antioxidative role throughout the differentiation process of AD-MSCs into DAergic neural cells","PeriodicalId":11568,"journal":{"name":"Egyptian Pharmaceutical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139364454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonribosomal peptides are considered one of these alternatives which produced by wild spectrum of bacteria. Objective Detection of nonribosomal peptide synthesis from Lactiplantibacillus plantarum LMG100 probiotic strain isolated from traditional lactic fermenting foods as alternative antimicrobial agent is important to human health and immune system. Materials and methods The identification of isolated strains using 16S rDNA technique was performed and followed by bioinformatics analysis tools; AntiSmash, PKS-NRPS analysis website, LSI based A-domain function predictor, NRPS predictor2, clustering using PhyML 3.0 to detect adenylation domain substrate specificity of NRP synthetases genes cluster of Lactiplantibacillus plantarum LMG100. To prove the presence of the NRP synthetases genes cluster, degenerate primers protocol and three sets of primers covered the five gene cluster were designed based on the original reference strain L. plantarum WCFS1. Antibacterial activity of the isolated strain was detected against bacterial strains from coliform group of the enteric genera of Escherichia, Salmonella and Shigella which formed the ordinary gastrointestinal tract infection. Results and conclusion The isolated L. plantarum LMG100 strain showed 99.96% of identity to 16S rDNA partial gene sequence of Lactiplantibacillus plantarum WCFS1 strain and bioinformatics analysis tools revealed the presence of NRPS gene cluster of five genes; two biosynthetic genes npsA and npsB from the five genes encoded for polypeptide of six amino acids, but six different predictors programs couldn’t assign the specificity of all adenylation domains except A4 serine and A5 glycine. The use of degenerate primers confirmed the presence of the NRPS in the isolated strain L. plantarum LMG100 compared to the standard strain WCFS1. Three sets of primers covering the five gene cluster were designed based on the original reference strain L. plantarum WCFS1 complete genome sequence confirmed the same organization of the putative gene cluster. In general, the approach of degenerated primers proved the presence of polypeptide NRPs gene presence in lactobacilli isolates. The new polypeptide NRP produced from the strain LMG100 showed maximum inhibition zones against G-ve short-rods bacterial strains from the coliform group of the enteric genera of Escherichia, Salmonella and Shigella which formed the ordinary gastrointestinal tract infection, and the minimal inhibitory concentrations (MIC) for G-ve bacterial strains was approximately of 125 mg.ml−1.

In vitro culture techniques, which ensure rapid, consistent, and uniform mass production, are indispensable for manufacturing important plant-derived metabolites. However, insufficient information is available regarding the tissue culture of Euphorbia milii and its important bioactive compounds. This study mainly aims to explore the impact of different carbon sources on callus formation, pigment accumulation, and antiviral activity of E. milii. Materials and methods Using inflorescence tissues as explants, we investigated the effects of different types and concentrations of plant growth regulators (2,4-dichlorophenoxyacetic acid [2,4-D], alone or combined with benzyl aminopurine) on callus induction frequency. Moreover, we studied the effects of different concentrations of carbon sources (glucose, fructose, and mannose) on callus growth, pigment (chlorophylls, carotenoids, and anthocyanins) accumulation, and antiviral activities. Results and conclusion The results indicated that 2,4-D alone (1.0 mg/l or 1.5 mg/l) induced callus formation most effectively. Furthermore, glucose was detected to be the more effective carbon source for the accumulation of chlorophylls, carotenoids, and anthocyanins compared with fructose and mannose. The highest accumulation of pigments was induced by 20 or 40 mg/l glucose supplements, with no significant difference between the effects of different concentrations. Unlike glucose, fructose or mannose did not enhance pigment accumulation; moreover, high concentrations had negative effects on pigment accumulation. Similarly, glucose was more suitable for the antiviral activity of E. milii extracts than fructose and mannose. The results will support the effective production of secondary metabolites and offer insights into the antiviral potency of E. milii.","PeriodicalId":11568,"journal":{"name":"Egyptian Pharmaceutical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42848886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the aim of this study was to investigate the immunomodulatory properties of Silene succulenta Forssk. extract that is a common herb growing in Egypt. Materials and methods S. succulenta was collected from Mediterranean coast region of Egypt, dried in shade, ground, and extracted using methanol. The effect of the plant extract on immune cells was tested using murine splenocytes and human peripheral blood mononuclear cells (PBMCs) proliferation colorimetric assays. A bioassay-directed fractionation was applied to identify the most active fraction and gas chromatography–mass spectrometry (GC–MS) was used to analyze it. The effect of the plant extract and its active fraction on human interleukin-2 (IL-2) was determined using enzyme-linked immunosorbent assay. Furthermore, the effect on macrophage nitric oxide production ability, macrophage viability, and HL-60-differentiated cells to neutrophil ROS production was tested. Results and conclusion Our results demonstrated that S. succulenta extract induced murine splenocytes and PBMCs proliferation in a concentration-dependent manner. Through bioassay-directed fractionation, we identified hexane subfraction as the active fraction of the extract and identified 18 compounds using GC–MS with major components of palmitic acid (33.19%) and phthalic acid, di(6-methylhept-2-yl) ester (20.22%). The extract and its active fraction induced human IL-2, whereas they inhibited macrophage nitrite-production ability, and neutrophil reactive oxygen species production level. We concluded that S. succulenta possesses several immunostimulatory and anti-inflammatory properties that can be utilized to treat several diseases.","PeriodicalId":11568,"journal":{"name":"Egyptian Pharmaceutical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139366191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Strong hepatocarcinogen diethyl nitrosamine (DENA) is a well-known substance. It is well known that DENA damages DNA repair enzymes and is typically used to cause liver cancer in experimental animal models, such as rats. Cerastes cerastes L-amino acid oxidase (Cc-LAAO) has hepatoprotective, antioxidant, and anticancer effects. Objective To assess the effectiveness of L-amino acid oxidase (LAAO) as a hepatoprotective agent in comparison to paclitaxel (PAC) as a conventional anticancer medicine in the early identification of HCC using biomarkers [alpha-fetoprotein (AFP) and carcinoembryonic antigen (CEA)], various liver function tests, and oxidant and antioxidant tests. Materials and methods CCl4 (200 mg/kg b.wt.) was injected subcutaneously once a week for 3 weeks after a single IP dose of DENA (200 mg/kg b.wt.) to develop hepatocellular cancer in rats. Twenty-five adult, mature, healthy rats were used in this investigation; their average weight was 100±10 g, and they were divided into five groups, each with five rats. After the experiment, some hepatic tests, histology of the liver, a tumor biomarker, and some kidney functions were assessed for all groups. Results and conclusion ASAT, ALAT, ALP, total bilirubin, tumor markers AFP, CEA, and lipid peroxides malondialdehyde (MDA) significantly rose in serum after DENA administration in rats, whereas activating antioxidants like SOD, CAT, GPx, and GSH decreased. LAAO and paclitaxel significantly ameliorated biomarkers for liver damage, lipid peroxides (MDA), antioxidants such as (SOD), (CAT), (GSH), (GPx), tumor marker (AFP), and (CEA) compared with the HCC group. Histopathology showed vacuolar hepatocytes with dispersed hepatocyte necrosis and infiltration of mononuclear cells. When used with DENA, the LAAO administration reduced negative effects and produced positive effects. These findings demonstrate that LAAO prevents liver HCC caused by DEN by preventing lipid peroxidation, hepatic cell oxidative stress, and boosting the antioxidant system.","PeriodicalId":11568,"journal":{"name":"Egyptian Pharmaceutical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41691340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is classified in the mint family (Lamiaceae) and commonly used as a landscape plant. Monoterpenes and sesquiterpenes are the most common chemical components found in essential oils. Because of these compounds, it is used for antifungal, antibacterial, and antioxidant activities. Secondary metabolite compounds, that is, jasmonic acid (JA) and methyl jasmonate (MeJA), significantly influence secondary metabolism regulation by stimulating the accumulation of phenols, flavonoids, and alkaloids. Objective The research aimed to estimate the effect of both JA and MeJA on growth parameters, chemical composition, particularly secondary metabolism, and the composition of volatile oils of L. angustifolia Mill plants. Materials and methods In the experiment, JA concentrations of 0, 1, 5, and 10 mM and MeJA concentrations of 0, 0.25, 0.50, and 1.0 mM were used as foliar spray applications on L. angustifolia. The investigation was performed as a randomized complete block design in three replicates. The parameters collected were different growth parameters, essential oil components using gas chromatography–mass spectrometry, the number of glands and secretory trichome diameter by scanning electron microscope, as well as chemical constituents. Results and conclusion The results showed that growth parameters were increased gradually with the increasing of JA and MeJA concentrations. The effects of JA and MeJA at high concentrations were more effective on all the growth parameters, biochemical components, and the number of glands and diameter of secretory trichomes than other concentrations and control plants in both seasons. JA application significantly increased chlorophyll a and b, carotenoids, and N and protein content of lavender plants. MeJA gave the highest values of total sugar, free amino acids, and phenols. Therefore, the results suggested that 10 mM of JA and 1.0 mM of MeJA significantly stimulate lavender plant growth and chemical compounds and volatile oil components, especially linalool and camphor, increasing its value and raising its quality in the perfume and cosmetics industries and various chemical industry applications.","PeriodicalId":11568,"journal":{"name":"Egyptian Pharmaceutical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139365769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
