Antibacterial activity is the most investigated biological property of honey. The goal this study was to evaluate antibacterial 57 Slovak blossom honeys against Staphylococcus aureus and Pseudomonas aeruginosa investigate role several bioactive substances in action honeys. Inhibitory bactericidal activities were studied determine minimum inhibitory concentrations. contents glucose oxidase (GOX) enzyme, hydrogen peroxide (H2O2), total polyphenols (TP) determined We found that honey samples...
Sida acuta is a shrub indigenous to pantropical regions. The plant widely used for its various pharmacological properties. Among compounds of interest occurring in the plant, are indoloquinoline alkaloids. aim present study was investigate antimicrobial activity alkaloids S. from Burkina Faso. had good against test microorganisms. In agar-well diffusion assay, highest inhibition zone diameters were recorded with Gram-positive bacteria. broth microdilution assay gave minimal inhibitory...
Previous studies have suggested that P. aeruginosa possesses redundant zinc uptake systems. To identify uncharacterized transporters, we analyzed the genome-wide transcriptional responses of PA14 to restriction. This approach led identification an operon (zrmABCD) regulated by regulator Zur, encodes for a metallophore-mediated import system. includes genes TonB-dependent Outer Membrane Protein (ZrmA) and putative nicotianamine synthase (ZrmB). The simultaneous inactivation ZnuABC transporter...
Abstract There is a growing interest in therapeutically targeting the inflammatory response that underlies age-related chronic diseases including obesity and type 2 diabetes. Through integrative small RNA sequencing, we show presence of conserved plant miR159a miR156c dried nuts having high complementarity with mammalian TNF receptor superfamily member 1a (Tnfrsf1a) transcript. We detected both exosome-like nut nanovesicles (NVs) demonstrated such NVs reduce Tnfrsf1a protein dampen TNF-α...
Abstract BACKGROUND: Twenty‐seven Italian honey samples of different floral origin were analysed for total phenolic and flavonoid contents by a spectrophotometric method antioxidant power radical‐scavenging activity the ferric‐reducing/antioxidant (FRAP) 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) assays respectively. In addition, profiles using high‐performance liquid chromatography with UV detection (HPLC‐UV). RESULTS: The results this study showed that contains copious amounts phenolics...
Different studies described the antibacterial properties of Lavandula angustifolia (Mill.) essential oil and its anti-inflammatory effects. Besides, no data exist on ability to activate human macrophages during innate response against Staphylococcus aureus. The discovery promising regulators macrophage-mediated inflammatory response, without side effects, could be useful for prevention of, or as therapeutic remedy for, various inflammation-mediated diseases. This study investigated, by...
Saffron, the most expensive spice in world, is got by Crocus sativus L. stigmas. The production of this substance has attracted human interest, since ancient cultures, for its medicinal and culinary properties. Because saffron high economic value, sometimes, Middle Ages, it adulterated with other vegetal materials, dyes or synthetic molecules. Object work was study one best world saffron: Civitaretenga (AQ, Central Italy) C. sativus. Taste, color aroma were determined, according to...
Abstract Environmental antibiotic contamination is due mainly to improper and illegal disposal of these molecules that, yet pharmacologically active, are excreted by humans animals. These compounds contaminate soil, water plants. Many studies have reported the bioaccumulation antibiotics in plants their negative effects on photosynthesis, cell growth oxidative balance. Therefore, principal objective this paper was study accumulation sites its uptake modality. Iberis sempervirens L ., grown...
Abstract Human microvesicles are key mediators of cell–cell communication. Exosomes function as microRNA transporters, playing a crucial role in physiological and pathological processes. Plant (MVs) display similar features to mammalian exosomes, these MVs might enhance plant delivery mammals. Considering that microRNAs have been newly identified bioactive constituents medicinal plants, their potential regulators mammals has underlined, this study, we characterized purified from Moringa...
Our world is facing an environmental crisis that driving scientists to research green and smart solutions in terms of the use renewable energy sources low polluting technologies. In this framework, photovoltaic (PV) technology one most worthy interest. Dye-sensitized solar cells (DSSCs) are innovative PV devices known for their encouraging features cost easy fabrication, good response diffuse light colour tunability. All these make DSSCs suitable being applied so-called agrovoltaic field,...
African ethnomedicine is essentially based on the traditional use of vegetal extracts. Since these natural drugs have shown health giving properties, in present study we increased further scientific basis supporting data. We investigated effects, murine B16F10 melanoma cells, plant extracts that were directly obtained by a Cameroon 'traditional healer'. After preliminary antioxidant functions compounds, already abundant literature, Moringa oleifera Lam., Eremomastax speciosa (Hochst.) Cufod...
Dioecism characterizes many crop species of economic value, including kiwifruit (Actinidia deliciosa). Kiwifruit male sterility occurs at the microspore stage. The cell walls microspores and pollen male-sterile male-fertile flowers, respectively, differ in glucose galactose levels. In numerous plants, formation involves normal functioning degeneration timing tapetum, with calcium carbohydrates provided by tapetum essential for fertility. aim this study was to determine whether anther wall...
Moringa oleifera is a widespread plant with substantial nutritional and medicinal value. We postulated that microRNAs (miRNAs), which are endogenous, noncoding small RNAs regulating gene expression at the post-transcriptional level, might contribute to properties of plants this species after ingestion into human body, expression. However, knowledge scarce about miRNA in Moringa. Furthermore, order test hypothesis on pharmacological potential miRNA, we conducted high-throughput sequencing...
Beyond nutrition, fruits and vegetables can be considered as natural sources of bioactive molecules, for which beneficial effects on human health are widely recognised. To improve food quality, soilless growing systems could represent a good strategy promoting sustainable production chain, although the nutritional nutraceutical properties their products should investigated in depth. The main quality traits volatile non-volatile secondary metabolites Solanum lycopersicum L., Petroselinum...
Functional foods include compounds with nutritional and health properties. The human diet could play a stronger role in cancer prevention. Only few studies have described the presence of plant small RNA, humans who were fed foods, which demonstrated ability these molecules to modulate consumer's genes evidenced existence plant-animal regulation. Through silico prediction, Olea europaea RNAs (sRs), had been previously reported as miRNAs, identified, each functional homology hsa-miR34a....
Bees represent an important element for the preservation of plant biodiversity. During their activities, bees cover a large area around hive and products strictly reflect distinctive traits these environments. In honey, floral diversity areas inspected by is revealed pollen spectra. The present work characterized 460 Italian unifloral honeys melissopalynological physicochemical analyses. Obtained data contributed to: confirm botanical identity samples; determine biodiversity in each honey;...
