| 1 | Eco-morphological characteristics of fern species for slope conservation显示文摘Degradation of slopes due to shallow landslide and the subsequent erosional processes are a big challenge on the application of soil bioengineering techniques; that is the use of plants as main structural components of a slope protection and conservation system. An optimal application of soil bioengineering techniques should include not only the technical factor of plants as structural components but also the ecology of species and the plant adaptations to disturbances, which is crucial if a longterm successful slope restoration system is intended. Ferns are a dominant understory vegetation species in the forest of Japan, but its characteristics and influences on the recovery of shallow landslide scars have not been fully studied yet. This study aims to find out the ecological characteristics of fern species through the calculation of ecological indicators and the quantification of the morphological features of specimens growing on disturbed and non-disturbed forest slopes in Japan. Gleichenia japonica was found as the vegetation species with biggest ecological indicators on both slopes. The analysis of morphological characteristics of the specimens growing on both sites showed that the development of the specimens is focused in below-ground characteristics. The pull-out force of Gleichenia japonica root system as an indicator of ecological adaptation to a constraint environment and morphological characteristics quality is influenced by height and root length according to the principal component analysis. The eco-morphological characteristics of species can be used as an indicator of an optimal element in soil bioengineering establishment for slope conservation proposes. The long and fibrous root system could be placed on forest roads, steep or small slopes where space limitation is an issue for the establishment of bigger species and if the slope conditions allow it, it can control soil losses due to rainfall and provide stability. | Laura SANCHEZ-CASTILLO Ken’ichirou KOSUGI Naoya MASAOKA Tetsuya KUBOTA | 2019 | Journal of Mountain Science2019，16，3： | 4 |
| 2 | Shear wave elastography in hepatitis C patients before and after antiviral therapy显示文摘AIM To investigate shear wave(SW) propagation velocity in patients with untreated hepatitis C and patients with sustained virological response(SVR). METHODS A total of 136 hepatitis C patients [85 patients who had not received antiviral therapy(na?ve group) and 51 patients who had received antiviral therapy and subsequently achieved SVR of at least 24 wk(SVR group)] and 58 healthy volunteers and outpatients without liver disease(control group) underwent evaluation of liver stiffness by SW elastography(SWE). Various parameters were evaluated in the chronic hepatitis C patients at the time of SWE.RESULTS SW propagation velocity(Vs) was 1.23 ± 0.14 m/s in the control group, 1.56 ± 0.32 m/s in the SVR group, and 1.69 ± 0.31 m/s in the na?ve group. Significant differences were seen between the control group and the SVR group(P = 0.0000) and between the SVR group and the na?ve group(P = 0.01417). All four fibrosis markers were higher in the na?ve group than in the SVR group. In the na?ve group, Vs was positively correlated with alanine aminotransferase(ALT)(r = 0.5372), α feto protein(AFP)(r = 0.4389), type Ⅳ collagen(r = 0.5883), procollagen Ⅲ peptide(P-Ⅲ-P)(r = 0.4140), hyaluronic acid(r = 0.4551), and Mac-2 binding protein glycosylation isomer(M2BPGi)(r = 0.6092) and negatively correlated with albumin(r =-0.4289), platelets(r =-0.5372), and prothrombinactivity(r =-0.5235). On multiple regression analysis, Vs was the most strongly correlated with ALT(standard partial regression std β = 0.4039, P = 0.00000). In the SVR group, Vs was positively correlated with AFP(r = 0.6977), type IV collagen(r = 0.5228), P-Ⅲ-P(r = 0.5812), hyaluronic acid(r = 0.5189), and M2BPGi(r = 0.6251) and negatively correlated with albumin(r =-0.4283), platelets(r =-0.4842), and prothrombin activity(r =-0.4771). On multiple regression analysis, Vs was strongly correlated with AFP(standard partial regression std β = 0.5953, P = 0.00000) and M2BPGi(standard partial regression std β = 0.2969, P = 0.03363).CONCLUSION In hepatitis C patients, liver stiffness is higher in treatment-na?ve patients than in those showing SVR. SWE may be a predictor of hepatocarcinogenesis in SVR patients. | Toshikuni Suda Osamu Okawa Rion Masaoka Yoshinori Gyotoku Naohiko Tokutomi Yasumi Katayama Masaya Tamano | 2017 | World Journal of Hepatology2017，9，1： | 4 |
| 3 | Enhanced plasma ghrelin levels in Helicobacter py/ori-colonized, interleukin-1-receptortype 1-homozygous knockout (IL-1R1-/-) mice显示文摘AIM: Ghrelin is an endogenous ligand for the growth hormone secretagogue receptor, and it plays a role in stimulating the growth hormone secretion, food intake, body weight gain and gastric motility. Eradication of Helicobacterpylori (H pylori) was shown to be associated with increase of the body weight. On the other hand, H pylori infection evokes the release of gastric IL-lp. The present study was designed to investigate the involvement of the gastric IL-1 signal in the ghrelin dynamics in Hpylori-colonized mice. METHODS: Twelve-week-old female IL-1-receptor type 1-homozygous-knockout mice (IL-1R1-/-') and their wild-type littermates (WT) were orally inoculated with H pylori (Hp group), while other cohorts received oral inoculation of culture medium (Cont group). Thirteen weeks after the inoculation, the mice were examined. The plasma and stomach ghrelin levels and the gastric preproghrelin mRNA were measured. RESULTS: Although the WT mice with H pylori infection showed a significantly decreased body weight as compared with that of the animals without H pylori infection, H pylori infection did not influence the body weight of the IL-1R1-knockout (IL-1R1-/-) mice. In the H pylori-infected IL-1R1-/-mice, the total and active ghrelin levels in the plasma were significantly increased, and the gastric ghrelin level was decreased. No significant differences were noted in the gastric preproghrelin mRNA expression. CONCLUSION: Ghrelin secretion triggered by H pylori infection might be suppressed by IL-1β, the release of which is also induced by the infection, resulting in the body weight loss of mice with H pylori infection. | Yuka Abiko Hidekazu Suzuki Tatsuhiro Masaoka Sachiko Nomura Kumiko Kurabayashi Hiroshi Hosoda Kenji Kangawa Toshifumi Hibi | 2005 | World Journal of Gastroenterology2005，11，27： | 3 |
