| 1 | Intestinal alkaline phosphatase in the colonic mucosa of children with inflammatory bowel disease显示文摘AIM:To investigate intestinal alkaline phosphatase(iAP) in the intestinal mucosa of children with inflammatory bowel disease(IBD).METHODS:Colonic biopsy samples were taken from 15 newly diagnosed IBD patients and from 10 healthy controls.In IBD patients,specimens were obtainedboth from inflamed and non-inflamed areas.The iAP mRNA and protein expression was determined by reverse transcription-polymerase chain reaction and Western blotting analysis,respectively.Tissue localization of iAP and Toll-like receptor(TLR) 4 was investigated by immunofluorescent staining.RESULTS:The iAP protein level in the inflamed mucosa of children with Crohn's disease(CD) and ulcerative colitis(UC) was significantly decreased when compared with controls(both P < 0.05).Similarly,we found a significantly decreased level of iAP protein in the inflamed mucosa in CD compared with non-inflamed mucosa in CD(P < 0.05).In addition,the iAP protein level in inflamed colonic mucosa in patients with UC was decreased compared with non-inflamed mucosa in patients with CD(P < 0.05).iAP protein levels in the non-inflamed mucosa of patients with CD were similar to controls.iAP mRNA expression in inflamed colonic mucosa of children with CD and UC was not significantly different from that in non-inflamed colonic mucosa with CD.Expression of iAP mRNA in patients with noninflamed mucosa and in controls were similar.Co-localization of iAP with TLR4 showed intense staining with a dotted-like pattern.iAP was present in the inflamed and non-inflamed mucosa of patients with CD,UC,and in control biopsy specimens,irrespective of whether it was present in the terminal ileum or in the colon.However,the fluorescent signal of TLR4 was more pronounced in the colon compared with the terminal ileum in all groups studied.CONCLUSION:Lower than normal iAP protein levels in inflamed mucosa of IBD patients may indicate a role for iAP in inflammatory lesions in IBD.Based on our results,administration of exogenous iAP enzyme to patients with the active form of IBD may be a therapeutic option. | Kriszta Molnár dám Vannay Beáta Szebeni Nóra Fanni Bánki Erna Sziksz ron Cseh Hajnalka Gyrffy Péter László Lakatos Mária Papp András Arató Gábor Veres | 2012 | World Journal of Gastroenterology2012,18,25: | 5 |
| 2 | Phytochemical overview and medicinal importance of Coffea species from the past until now显示文摘Coffea(coffee) species are grown in almost all countries along the Equator. Many members of the genus have a large production history and an important role both in the global market and researches. Seeds(Coffeae semen) are successfully used in food, cosmetic, and pharmaceutical industries due to its caffeine and high polyphenol content. Nowadays, the three best-known coffee species are Arabic(Coffea arabica L.), Robusta(Coffea robusta L. Linden), and Liberian coffees(Coffea liberica Hier.). Even though, many records are available on coffee in scientific literature, wild coffee species like Bengal coffee(Coffea benghalensis Roxb. Ex Schult.) could offer many new opportunities and challenges for phytochemical and medical studies. In this comprehensive summary, we focused on the ethnomedicinal, phytochemical, and medical significance of coffee species up to the present. | éva Brigitta Patay Tímea Bencsik Nóra Papp | 2016 | Asian Pacific Journal of Tropical Medicine2016,9,12: | 4 |
| 3 | Multiple haploids, triploids, and tetraploids found in modern-day “living fossil” Ginkgo biloba显示文摘Ginkgo biloba,the last extant representative of a lineage of Mesozoic gymnosperms,is one of the few seed plants with an exceptionally long(~300 Myr)evolutionary history free of genome-wide duplications(polyploidy).Despite this genome conservatism,we have recently found a viable spontaneous tetraploid Ginkgo sapling during routine screening of several plants,demonstrating that natural polyploidy is possible in Ginkgo.Here we provide a much wider flow cytometry survey of ploidy in some European Ginkgo collections,and own seedlings(>2200 individuals and~200 cultivars).We found a surprisingly high level of ploidy variation in modern-day Ginkgo and documented altogether 13 haploid,3 triploid,and 10 tetraploid Ginkgo plants or cultivars,most of them being morphologically distinct from common diploids.Haploids frequently produced polyploid(dihaploid)buds or branches.Tetraploids showed some genome size variation.The surveyed plants provide a unique resource for future Ginkgo research and breeding,and they might be used to accelerate the modern diversification of this nearly extinct plant lineage. | PetrŠmarda Lucie Horová Ondřej Knápek Heidi Dieck Martin Dieck Katarína Ražná Pavel Hrubík Laszlo Orlóci Laszlo Papp Kristýna Veselá Pavel Veselý Petr Bureš | 2018 | Horticulture Research2018,5,1: | 4 |
| 4 | Antioxidant potential,tannin and polyphenol contents of seed and pericarp of three Coffea species显示文摘Objective:To investigate the antioxidant activity,total phenolic and total tannin content of the pericarp and the seed of Coffea benghalensis(C.benghalensis) and Coffea liberica compared to Coffea arabica(C.arabica).Methods:The antioxidant potential,total tannin and polyphenol contents of the immature and mature seed and pericarp of C.benghalensis and Coffea liberica were quantified and compared to C.arabica.Enhanced chemiluminescence(ECL).2,2-diphenyl-1-picrylhydruzyl(DPPH).oxygen radical absorbance capacity,Folin-Ciocaltcau method and total tannin content assays were used.Results:Trolox equivalent(TE/g plant material) values obtained by ECL and DPPH methods showed loose correlation(r^2=0.587)while those measured by oxygen radical absorbance capacity assay were higher without correlation in each plant.A closer correlation was detected between the ECL method and the percentage antioxidant activity of the DPPH technique(r^2=0.610 7) in each species,however the immature pericarp of C.benghalensis showed much higher DPPH scavenging potential than was seen in the ECL assay.The immature pericarp of C.benghalensis expressed the highest tannin and polyphenol content,and a high polyphenol level was also detected in the immature seed of C.arabica.The immature pericarp of Bengal and Liberian coffees showed the largest amount of phenolic contents.Conclusions:The obtained data highlight the potential role of C.benghalensis as a new source of natural antioxidants and polyphenols compared to C.arabica. | va Brigitta Patay Nikolett Sali Tams Kszegi Rita Csepregi Viktória Lilla Blaz Tibor Sebastian Németh Tibor Németh Nóra Papp | 2016 | Asian Pacific Journal of Tropical Medicine2016,9,4: | 3 |
