2Farinose fiavonoids are associated with high freezing tolerance in fairy primrose (Primula malacoides) plants显示文摘The deposition of surface(farinose)fiavonoids on aerial parts of some Primula species is a well-documented but poorly understood phenomenon.Here,we show thatfiavonoid deposition on the leaves and winter buds may contribute strongly to preventing freezing damage in these plants.The ice nucleation temperature of fairy primrose(Primula malacoides)leaves covered with naturalfiavone was approximately 6°C lower compared to those that had theirfiavone artificially removed.Additionally,farinosefiavonoids on the leaves reduced subsequent electrolyte leakage(EL)from the cells exposed to freezing temperatures.Interestingly,exogenous application offiavone at4 mg/g fresh weight to P.malacoides leaves,which had the originalfiavone mechanically removed,restored freezing tolerance,and diminished EL from the cells to pretreatment values.Our results suggest that farinosefiavonoids may function as mediators of freezing tolerance in P.malacoides,and exogenous application offiavone could be used to reduce freezing damage during sudden but predictable frost events in other plant species.Ryutaro Isshiki Ivan Galis Shigemi Tanakamaru 2014Journal of Integrative Plant Biology2014,56,2:3
3Biological efficacy of perpendicular type-I collagen protruded from TiO_(2)-nanotubes显示文摘The aim of this study was to evaluate the biological efficacy of a unique perpendicular protrusion of type-I collagen(Col-I)from TiO2 nanotubes(NT-EPF surface).We hypothesized that the NT-EPF surface would play bifunctional roles in stimulating plateletmediated fibroblast recruitment and anchoring fibroblast-derived Col-I to form a perpendicular collagen assembly,mimicking the connective tissue attachment around natural teeth for the long-term maintenance of dental implants.Ti surface modification was accomplished in two steps.First,TiO2 nanotubes(NT)array was fabricated via anodization.Diameters and depths of NTs were controlled by applied voltage and duration.Subsequently,an electrophoretic fusion(EPF)method was applied to fuse Col-I into nanotube arrays in a perpendicular fashion.Surface wettability was assessed by contact angle measurement.The bioactivity of modified TiO2 surfaces was evaluated in terms of NIH3T3 fibroblast attachment,platelet activation,and collagen extension.Early attachment,aggregation,and activation of platelets as well as release of platelet-related growth factors were demonstrated on NTEPF surfaces.Platelet-mediated NIH3T3 cells migration toward NT-EPF was significantly increased and the attached cells showed a typical fibrous morphology with elongated spindle shape.A direct linkage between pseudopod-like processes of fibroblasts to NTEPF surfaces was observed.Furthermore,the engineered EPF collagen protrusion linked with cell-derived collagen in a perpendicular fashion.Within the limitation of this in vitro study,the TiO2 nanotube with perpendicular Col-I surface(NT-EPF)promoted better cell attachment,induced a strong platelet activation which suggested the ability to create a more robust soft tissue seal.Chia-Yu Chen David M.Kim Cliff Lee John Da Silva Shigemi Nagai Toshiki Nojiri Masazumi Nagai 2020International Journal of Oral Science2020,12,4:3
4Epithelial cell adhesion efficacy of a novel peptide identified by panning on a smooth titanium surface显示文摘Epithelial attachment via the basal lamina on the tooth surface provides an important structural defence mechanism against bacterial invasion in combating periodontal disease. However, when considering dental implants, strong epithelial attachment does not exist throughout the titanium-soft tissue interface, making soft tissues more susceptible to peri-implant disease. This study introduced a novel synthetic peptide(A10) to enhance epithelial attachment. A10 was identified from a bacterial peptide display library and synthesized. A10 and protease-activated receptor 4-activating peptide(PAR4-AP, positive control) were immobilized on commercially pure titanium. The peptide-treated titanium showed high epithelial cell migration ability during incubation in platelet-rich plasma. We confirmed the development of dense and expanded BL(stained by Ln5) with pericellular junctions(stained by ZO1) on the peptide-treated titanium surface. In an adhesion assay of epithelial cells on A10-treated titanium, PAR4-AP-treated titanium, bovine root and non-treated titanium, A10-treated titanium and PAR4-AP-treated titanium showed significantly stronger adhesion than non-treated titanium. PAR4-AP-treated titanium showed significantly higher inflammatory cytokine release than non-treated titanium. There was no significant difference in inflammatory cytokine release between A10-treated and non-treated titanium. These results indicated that A10 could induce the adhesion and migration of epithelial cells with low inflammatory cytokine release. This novel peptide has a potentially useful application that could improve clinical outcomes with titanium implants and abutments by reducing or preventing peri-implant disease.Hidemichi Kihara David M.Kim Masazumi Nagai Toshiki Nojiri Shigemi Nagai Chia-Yu Chen Cliff Lee Wataru Hatakeyama Hisatomo Kondo John Da Silva 2018International Journal of Oral Science2018,10,3:2
5Regular arrangement of collecting venules:Does patient age affect its accuracy?显示文摘AIM:To address the diagnostic value of the regular arrangement of collecting venules(RAC)among old age patients. METHODS:A total of 390 consecutive patients whose Helicobacter pylori(H.pylori)status was known and who received upper gastrointestinal endoscopy,were retrospectively studied for the presence or absence of RAC as well as gastric mucosal atrophy.The sensitivity, specificity,positive predictive value,negative predic-tive value and accuracy of RAC to detect normal gastric mucosa were assessed and were compared among two different age groups of patients. RESULTS:The mean age±standard deviation(SD)of included patients(n=390),was 62.9±13 years.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of RAC to detect normal gastric mucosa were 91.7%,66.1%,18.8%,99%and 68.1%respectively.Although the sensitivity,specificity,positive predictive value,negative predictive value and accuracy of RAC among patients<60 years(n= 139)was 94.7%,71.2%,46.2%,98.1%and 76.1%,respectively,it was 80%,64.3%,5.1%,93%and 64.6%, respectively,among patients≥60 years(n=251). Younger Patients(<60 years),have highly significant rates of RAC sensitivity,positive predictive value,and accuracy(P≤0.001,≤0.001 and≤0.02,respectively).Older patients had highly significant rates of H. pylori infection and gastric mucosal atrophy(P≤0.01). CONCLUSION:Although RAC is a valuable sign for real-time identification of normal gastric mucosa,its accuracy seems to be affected by the patient's age.Alshimaa Alaboudy Ashraf Elbahrawy Shigemi Matsumoto Ghada M Galal Tsutomu Chiba 2011World Journal of Gastrointestinal Endoscopy2011,3,6:2
