Fragaria indica stem, leaf, and root extract was used to assess the antimicrobial activity against bla-TEM beta-lactamase producing Shigella flexneri, Salmonella typhi, and Escherichia coli. Ethanolic extracts of F. indica leaves exhibited a maximum zone of inhibition of 20 ± 1.2 mm (p < 0.001), 18 ± 1.4 mm (p < 0.001), and 16 ± 1.5 mm (p < 0.001) against E. coli, S. flexneri, and S. typhi, respectively. To identify different compounds, the bioactive ethanolic leaf extracts were further processed for HPLC, GC-MS, ADMET, and docking analysis. In the ethanolic leaf extract, 19 phenolic compounds were identified in HPLC analysis. Three phenolic compounds, including Isorhamnetin-3-rutinoside, 5, 7-Dihydroxy-4’ -methoxyflavone, and Luteolin, were for the first time reported in F. indica. In GC-MS analysis, sixteen compounds were identified. From the literature search, among the identified compounds, AlphaHimachalene, 1,3-Diphenyl-1-((trimethylsilyl)oxy)-1(Z)-heptene, 1H-Benzocycloheptene, Bicyclo[5.2.0] nonane, cis-1,1,3,4-Tetramethylcyclopentane, Bicyclo[2.2.2]octane-cis-2,3-diyl Carbonate, BetaHimachalene and 2-methylene-4,8,8-trimethyl-4-vinyl were reported for the first time in F. indica. Two compounds, including Alpha-Himachalene and Bicyclo[2.2.2]octane-cis-2,3-diyl carbonate, having good water solubility, drug likeness, and medicinal characteristics, were selected for docking analysis. Docking of Alpha-Himachalene and Bicyclo[2.2.2]octane-cis-2,3-diyl carbonate showed interaction with Pro-26, Phe-22, and Ala-23 residues of bacterial bla-TEM beta-lactamase. Similarly, Bicyclo[2.2.2] octane-cis-2,3-diyl carbonate interacts with amino acid residues of Ala-235 and Ser-233 of bla-TEM beta-lactamase. Further studies will help to characterize the anti-infective compounds against bla-TEM producing foodborne bacterial pathogens.

Introduction: Dietary inflammation is a significant risk factor for age-related cognitive impairments among older adults. However, information related to the relationship between Empirical Dietary Inflammatory Index (eDII) score and cognitive frailty (CF) among Malaysian community-dwelling older adults is still limited. The objective of this study is to determine the association between dietary inflammatory risk and CF among community-dwelling older adults. Method: This is a cross sectional study involving community-dwelling older adults in Klang Valley. The Fried’s Criteria and Clinical Dementia Rating (CDR) were used to determine CF status. Subjects were also interviewed using the Dietary History Questionnaire (DHQ) and eDII food checklist to assess the food intake and dietary inflammatory risk. Data collected was analyzed using SPSS version 26.0. Results: A total of 158 older adults (66.7 ± 5.2 years old) residing in Klang Valley were involved. Energy and macronutrients have a weak positive association with pro-inflammatory score (p<0.05). There is no significant mean difference between CF older adults consumed a more pro-inflammatory diet (mean 2.07 ± 1.10) compared to non CF (mean 2.06 ± 1.14). However, white rice food item significantly consumed by CF people (22.4%) than non CF (8.5%) (p<0.05). Conclusion: CF older adults were more likely to consume a pro-inflammatory diet particularly from the rice food group. There is a need to further assess the risk of consuming a pro-inflammatory diet using larger sample size and appropriate biomarkers.

Plants are alternative source of natural medicines due to secondary active metabolites. Fagonia cretica extracts and Gradient High-Pressure Liquid Chromatography fractionations were checked against multidrug-resistant gastrointestinal pathogens including, Salmonella typhi, Escherichia coli and Shigella flexneri. ESI-MS/MS analysis of bioactive HPLC fractions was performed to elucidate antibacterial compounds. F. cretica extracts exhibited potential antibacterial activity. Twenty-four (24) HPLC fractions were obtained from methanol, ethanol and aqueous extracts of F. cretica. Eighteen (18) fractions showed antibacterial activity, while no activity was observed by the remaining six (6) fractions. HPLC fractions, F1 (25g ± 0.20 mm) and F2 (15f ± 0.12 mm) of aqueous extract exhibited activity against multidrug resistant GI pathogens. Gallic acid, quinic acid, cyclo-l-leu-l-pro, vidalenolone, liquirtigenin, rosmarinic acid and cerebronic acid were identified in F1 fraction of aqueous extract, while succinic acid, cyclo (l-Leul-Pro) and liquirtigenin were identified in F2 fraction of aqueous extract through ESI-MS/MS analysis. F. cretica extracts and HPLC fractions showed potential activity against MDR GI pathogens. Vidalenolone, Cyclo-1-leu-1-pro and Cerebronic acid are first time reported in F. cretica. Further characterization of bioactive compounds from F. cretica may be helpful to elucidate antibacterial therapeutic molecules.

The objective of this study was to investigate the angiogenic potential of human chorion-derived stem cells (CDSC) cultured in medium containing bFGF and VEGF (EDM50). Total RNA was extracted from cells cultured in FD+10% FBS and EDM50. Quantitative RT-PCR was carried out to score the differential mRNA expression of genes involve in angiogenesis and endothelial differentiation. Our finding demonstrated that all angiogenic and endothelial associated genes were expressed higher in EDM50. Expression level of ANG-1, eNOS and VEGFR2 were significantly higher in EDM50 compared to FD+10% FBS. Our results suggested that human CDSC cultured in EDM50 can be used for angiogenesis purpose in regenerative medicine.

The aim of the study is to determine the neuronal and glial gene expression of cultured human amniotic epithelial cells (HAECs) in serial passages. HAECs obtained from human term placentae were cultured in F12:DMEM (1:1) + 10% FBS +10ng/ml EGF in serial passages. Quantitative RT-PCR was used to assess the gene expression analysis. The results showed that the cultured HAECs expressed the neural stem cell genes (Nestin, NSE and Vimentin), mature neuronal genes (TH, MAP-2, beta-III-tubulin and NFM) and glial genes (CNPase, MBP and Olig). These neural stem cell genes increased with serial passages while the genes expression for mature neuronal and glial cells were downregulated. These results suggested that HAECs may promote or involve in neurogenesis and gliagenesis.

The aim of the study is to evaluate the stemness gene expression of cultured human amniotic epithelial cells (HAECs) in serial passages. HAECs obtained from human term placentae were cultured in F12:DMEM(1:1) + 10% FBS +10ng/ml EGF in serial passages (P0, P1, P2 and P4). Quantitative RT-PCR was used to assess the gene expression analysis. The results showed that cultured HAECs expressed and downregulated the stemness genes expression for Oct-4, Sox-2, Nanog3, FGF4, Rex-1, FZD-9, BST-1 ABCG2. However, vimentin and nestin gene expression were upregulated. The results suggested that cultured HAECs may have pluripotent and multipotent properties.

Angiogenic induction was made to promote angiogenesis by differentiating stem cells towards endothelial cells. However, the stemness property of induced cells has not been revealed yet. Hence, we aim to evaluate the differential mRNA expression of stemness genes in human chorion-derived stem cells (CDSC) after being cultured in EDM50 comprised bFGF and VEGF. Results indicated that CDSC cultured in EMD50 expressed significantly higher mRNA level of Sox-2, FZD9, BST-1 and Nestin. In addition Oct-4, FGF-4 and ABCG-2 were also upregulated. Our finding suggested that CDSC after angiogenic induction enhanced its stem cell properties. This could be contributed for the mechanism of stem cell therapy in ischemic problem.
