Abstract
Oenothera paradoxa (EP) preparations are commonly used in folk medicine to treat skin diseases, neuralgia, and gastrointestinal (GI) disorders. Several reports suggested that EP preparations exhibit potent anti-inflammatory and antioxidant activities both in vitro and in vivo. Here, we aimed to characterize the action of EP pomace polyphenol extract in mouse model of colitis. We analyzed the composition of EP pomace polyphenol extract using reversed phase HPLC system and ultra-performance liquid chromatography (UPLC) system coupled with a quadrupole-time of flight (Q-TOF) MS instrument. Then, we used a well-established animal model of 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis to determine the anti-inflammatory action of EP pomace polyphenol extract. We also investigated the effect of the EP pomace polyphenol extract on pro-inflammatory (IL-1β and TNF-α) cytokine mRNA levels and hydrogen peroxide concentration in the inflamed colon. Administration of EP pomace polyphenol extract significantly improved macroscopic and microscopic damage scores, as well as myeloperoxidase (MPO) activity in TNBS-treated mice. The anti-inflammatory effect of the extract was observed after intracolonic and oral administration and was dose-dependent. Significant reduction of tissue hydrogen peroxide level after treatment with EP pomace polyphenol extract suggests that its therapeutic effect is a result of free radical scavenging. This novel finding indicates that the application of the EP pomace polyphenol extract in patients with inflammatory bowel diseases (IBDs) may become an attractive supplementary treatment for conventional anti-inflammatory therapy.

Abstract
Fruits traditionally used for liqueurs are a good source of phenolic compounds endowed with antioxidant activity. The aim of this study was to compare the content of phenolic compounds and anthocyanins and the antioxidant capacity of liqueurs made from red fruits. The liqueurs were made from fruits of 10 species: chokeberry, cornelian cherry, black rose, blackcurrant, blackberry, raspberry, mahonia, sloe, strawberry, and sour cherry. The liqueurs from black rose, chokeberry, sloe and mahonia fruits contained the most of substances which react with the Folin-Ciocalteu reagent (671, 329, 271 and 218 mg GAE/100 mL, respectively) and had the highest antioxidant activity. The samples stored at a temperature of 30 °C had antioxidant activity from 3% to 11% lower than the fresh samples. After 6 months, anthocyanins degraded almost completely in the samples stored at 30 °C and at 15 °C there was from 0% (blackcurrant liqueurs) to 47% (sloe liqueurs) of their initial content and slightly more in sweet liqueurs.

Abstract
Low concentrations of black tea and water extracts from medicinal plants Arctostaphylos uva-ursi, Vaccinium vitis-idaea, Tilia cordata, Betula pendula and Zea mays stimulated biofilm formation in Escherichia coli BW25113 up to three times. Similar effect was observed for tannic acid and low concentrations of quercetin. In contrast, the extract from Urtica dioica reduced biofilm production. Pretreatment with plant extracts variously modified antibiotic effects on specific biofilm formation (SBF). Extract from V. vitis-idaea increased SBF, while the extracts from Achillea millefolium, Laminaria japonica and U. dioica considerably decreased SBF in the presence of ciprofloxacin, streptomycin and cefotaxime. Stimulatory effect of the extracts and pure polyphenols on biofilm formation was probably related to their prooxidant properties. The rpoS deletion did not affect SBF significantly, but stimulation of biofilm formation by the compounds tested was accompanied by inhibition of rpoS expression, suggesting that a RpoS-independent signal transduction pathway was apparently used.

Abstract
The subject of study was the evaluation of antibacterial activities of rosmarinic acid (RA) on clinical Staphylococcus aureus strains obtained from catheter-related infections. Minimal inhibitory (MIC) and minimal bactericidal concentrations (MBC) of RA were tested by broth microdilution assay. Biofilm-eradication activity was detected on 24-hour biofilm in microtiter plates using a regrowth technique; activity on biofilm formation was measured by a microtiter plate method after RA application to bacterial samples after 0, 1, 3 and 6 hours of biofilm development. RA had antimicrobial activity on all tested strains in concentrations from 625 to 1250 μg.mL−1 (MICs equal to MBCs). No biofilm-eradication activity on 24-hour biofilm was observed in the tested range of concentrations (from 156 to 5000 μg.mL−1). Subinhibitory RA concentrations suppressed the biofilm production, when applied at early stages of its development. Concentrations lower than subinhibitory stimulated the biofilm mass production in a concentration- and time-dependent manner. Considering our results, RA could be a candidate for a topical antimicrobial agent with killing activity on planktonic forms of bacteria and suppressing activity in the early stages of biofilm development, but probably not for the therapy of catheter-related infections as a sole agent.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional usage suggests Citrus reticulata Blanco seeds have beneficial effects against infection. The purpose of this study was to investigate the effect of Citrus reticulata on the uroepithelium and to determine the mechanisms responsible for protection against urinary tract infection (UTI). MATERIALS AND METHODS Human bladder cell lines T24 and 5637 were employed in a cell culture infection model to determine the effects of Citrus reticulata treatment on Escherichia coli adherence and invasion of the uroepithelium. β1 integrin and caveolin-1 mRNA expression was assessed using RT real-time PCR. β1 integrin protein expression was confirmed by Western Blot. The effect of Citrus reticulata on bacteria was investigated using antibacterial sensitivity, yeast agglutination and biofilm assays. RESULTS Citrus reticulata treatment decreased β1 integrin expression and reduced bacterial invasion while adhesion of uroepithelial cells was not affected. Caveolin-1 expression was not influenced either and Citrus reticulata did neither exhibit any direct antimicrobial effect nor interfered with type 1 fimbriae binding. CONCLUSIONS Our results show that Citrus reticulata has a protective effect on the uroepithelium as seen by reduced bacterial invasion of uroepithelial cells. These properties suggest that seeds from Citrus reticulata may have therapeutic potential in preventing UTI.

Ethanolic Extract of Polish Propolis: Chemical Composition and TRAIL-R2 Death Receptor Targeting Apoptotic Activity against Prostate Cancer Cells. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:757628.

Abstract
Propolis possesses chemopreventive properties through direct anticancer and indirect immunomodulatory activities. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) plays a significant role in immunosurveillance and defense against cancer cells. TRAIL triggers apoptosis upon binding to TRAIL-R1 (DR4) and TRAIL-R2 (DR5) death receptors expressed on cancer cell surface. The activation of TRAIL apoptotic signaling is considered an attractive option for cancer prevention. However, as more tumor cells are reported to be resistant to TRAIL-mediated death, it is important to develop new strategies to overcome this resistance. The aim of this study was to investigate the chemical composition and proapoptotic mechanism of ethanolic extract of Polish propolis (EEP-P) against cancer cells. The identification and quantification of phenolic compounds in propolis extract were performed using HPLC-DAD and UPLC-Q-TOF-MS methods. TRAIL-resistant LNCaP prostate cancer cells were treated with EEP-P and TRAIL. Cytotoxicity was measured by MTT and LDH assays. Apoptosis was detected using annexin V-FITC staining by flow cytometry and fluorescence microscopy. Death receptors expression was analyzed using flow cytometry. Pinobanksin, chrysin, methoxyflavanone, p-coumaric acid, ferulic acid and caffeic acid were the main phenolics found in EEP-P. Propolis sensitized LNCaP cells through upregulation of TRAIL-R2. These results suggest that EEP-P supports TRAIL-mediated immunochemoprevention in prostate cancer cells.

Abstract
Infection with enterohemorrhagic Escherichia coli O157:H7 (EHEC) is a worldwide problem. Of the 498 plant extracts screened against EHEC, 16 inhibited the formation of biofilm of EHEC by >85% without inhibiting the growth of planktonic cells, and 14 plant extracts reduced the swarming motility of EHEC. The most active extract, Carex dimorpholepis, decreased swimming and swarming motilities and curli formation. Transcriptional analyses showed that the extract of C. dimorpholepis repressed curli genes, various motility genes, and AI-2 quorum sensing genes, which was corroborated by reduction in the production of fimbria, motility, and biofilm by EHEC. Trans-resveratrol at 10 μg ml(-1) in the extract of C. dimorpholepis was found to be a new anti-biofilm compound against EHEC, but importantly, the extract of C. dimorpholepis and trans-resveratrol did not inhibit the fomation of biofilm in four commensal E. coli strains. Furthermore, the extract of C. dimorpholepis decreased the adhesion of EHEC cells to human epithelial cells without affecting the viability of these cells.

Abstract
OBJECTIVE Staphylococcus aureus is a common opportunistic pathogen causing human infections. In the present study, we investigated photodynamic inactivation on S. aureus using hypocrellin B from a traditional Chinese herb. MATERIALS AND METHODS After incubation of S. aureus cells with different concentrations of hypocrellin B for 60 min, subsequent light irradiation from a novel LED light source with wavelength of 470 nm was combined with the energy density of 0.3 J/cm(2). Phototoxicity of hypocrellin B on S. aureus was investigated by colony forming unit assay. Membrane permeability was measured using confocal laser scanning microscopy (CLSM) with propidium iodide (PI) staining. Intracellular reactive oxygen species (ROS) level was measured using flow cytometry (FCM) with DCFH-DA staining. Morphology and structure of treated and controlled bacteria were observed using transmission electron microscopy (TEM). RESULTS Activity of S. aureus was substantially inhibited by photodynamic action in hypocrellin B dose-dependent manner. Notable damage to S. aureus were found in TEM after photodynamic treatment of hypocellin B. Red fluorescence of PI dye was observed more frequently in bacterial cells treated by photodynamic action of hypocrellin B than those of bacterial cells treated by the controls including sham control, hypocrellin B treatment alone and light irradiation alone. Intracellular ROS increase was also found in S. aureus treated by photodynamic action of hypocrellin B. CONCLUSION Photodynamic action of hypocrellin B markedly increased intracellular ROS level and caused damage to membrane permeability, resulting in cell death of S. aureus.

Abstract
The aim of this study was to investigate the chemical composition and anti-inflammatory effect of ethanolic extract of Brazilian green propolis (EEP-B) on LPS + IFN-γ or PMA stimulated J774A.1 macrophages. The identification and quantification of phenolic compounds in green propolis extract were performed using HPLC-DAD and UPLC-Q-TOF-MS methods. The cell viability was evaluated by MTT and LDH assays. The radical scavenging ability was determined using DPPH• and ABTS•+. ROS and RNS generation was analyzed by chemiluminescence. NO concentration was detected by the Griess reaction. The release of various cytokines by activated J774A.1 cells was measured in the culture supernatants using a multiplex bead array system based on xMAP technology. Artepillin C, kaempferide, and their derivatives were the main phenolics found in green propolis. At the tested concentrations, the EEP-B did not decrease the cell viability and did not cause the cytotoxicity. EEP-B exerted strong antioxidant activity and significantly inhibited the production of ROS, RNS, NO, cytokine IL-1α, IL-1β, IL-4, IL-6, IL-12p40, IL-13, TNF-α, G-CSF, GM-CSF, MCP-1, MIP-1α, MIP-1β, and RANTES in stimulated J774A.1 macrophages. Our findings provide new insights for understanding the anti-inflammatory mechanism of action of Brazilian green propolis extract and support its application in complementary and alternative medicine.
