1Modeling habitat suitability of range plant species using random forest method in arid mountainous rangelands显示文摘Mountainous rangelands play a pivotal role in providing forage resources for livestock, particularly in summer, and maintaining ecological balance. This study aimed to identify environmental variables affecting range plant species distribution, ecological analysis of the relationship between these variables and the distribution of plants, and to model and map the plant habitats suitability by the Random Forest Method(RFM) in rangelands of the Taftan Mountain, Sistan and Baluchestan Province, southeastern Iran. In order to determine the environmental variables and estimate the potential distribution of plant species, the presence points of plants were recorded by using systematic random sampling method(90 points of presence) and soils were sampled in 5 habitats by random method in 0–30 and 30–60 cm depths. The layers of environmental variables were prepared using the Kriging interpolation method and Geographic Information System facilities. The distribution of the plant habitats was finally modelled and mapped by the RFM. Continuous maps of the habitat suitability were converted to binary maps using Youden Index(?) in order to evaluate the accuracy of the RFM in estimation of the distribution of species potentialhabitat. Based on the values of the area under curve(AUC) statistics, accuracy of predictive models of all habitats was in good level. Investigating the agreement between the predicted map, generated by each model, and actual maps, generated from fieldmeasured data, of the plant habitats, was at a high level for all habitats, except for Amygdalus scoparia habitat. This study concluded that the RFM is a robust model to analyze the relationships between the distribution of plant species and environmental variables as well as to prepare potential distribution maps of plant habitats that are of higher priority for conservation on the local scale in arid mountainous rangelands.Hossein PIRI SAHRAGARD Majid AJORLO Peyman KARAMI 2018Journal of Mountain Science2018,15,10:7

3Hepatopancreatoduodenectomy for metastatic duodenal gastrointestinal stromal tumor显示文摘BACKGROUND: Duodenal gastrointestinal stromal tumors, which are rare, comprise 3%-5% of all gastrointestinal stromai tumors. We present a case of a metastatic duodenal gastrointestinal stromal tumor that was successfully treated by simultaneous tight hemihepatectomy and pancreaticoduodenectomy. METHODS: A 50-year-old woman was admitted to our department for the treatment of a possible metastatic duodenal gastrointestinal stromal tumor (GIST). At laparotomy a large duodenal tumor was found displacing the head of the pancreas. A 3 cm in diameter lesion in the posterior aspect of segment Ⅷ of the liver was also noted. Simultaneous right hepatectomy and pancreaticoduodenectomy were performed. RESULTS: Histological examination revealed a high grade metastatic duodenal GIST strongly positive for c-kit, CD34, and vimentin. The patient had no additional therapy. A follow-up of 21 months showed that the patient is very well and there is no evidence of recurrent diseases. CONCLUSIONS: Malignant stromai tumors of the duodenum are rarely encountered. They are usually slow growing, and may be amenable to curative surgery, even after occurrence of metastases. Resection of localized liver metastasis is still advocated when feasible, since imatinib does not provide a complete or long-term response. Combined surgical resection is an efficacious treatment for patients with metastatic duodenal gastrointestinal stromal tumor.Charalabos Stratopoulos Zahir Soonawalla Juan Piris Peter J Friend 2006Hepatobiliary & Pancreatic Diseases International2006,5,1:3
