| 1 | Increased levels of homocysteine in patients with ulcerative colitis显示文摘AIM: To investigate serum levels of homocysteine (Hcys) and the risk that altered levels carry for thrombosis development in ulcerative colitis (UC) patients. METHODS: 55 UC patients and 45 healthy adults were included. Hcys, vitamin B12 and folic acid levels were measured in both groups. Clinical history and thrombo- embolic events were investigated. RESULTS: The average Hcys level in the UC patients was 13.3 ± 1.93 μmmol/L (range 4.60-87) and was higher than the average Hcys level of the control group which was 11.2 ± 3.58 μmmol/L (range 4.00-20.8) (P < 0.001). Vitamin B12 and folic acid average values were also lower in the UC group (P < 0.001). Whenmultivariate regression analysis was performed, it was seen that folic acid deficiency was the only risk factor for hyperhomocysteinemia. Frequencies of thromboembolic complications were not statistically significantly different in UC and control groups. When those with and without a thrombosis history in the UC group were compared according to Hcys levels, it was seen that there were no statistically significant differences. A negative linear relationship was found between folic acid levels and Hcys. CONCLUSION: We could not find any correlations between Hcys levels and history of prior thromboembolic events. | Sabiye Akbulut Emin Altiparmak Firdevs Topal Ersan Ozaslan Metin Kucukazman Ozlem Yonem | 2010 | World Journal of Gastroenterology2010，16，19： | 13 |

| 4 | Illumination of parameter contributions on uneven break: phenomenon in underground stoping mines显示文摘One of the most serious conundrum facing the stope production in underground metalliferous mining is uneven break(UB: unplanned dilution and ore-loss). Although the UB has a huge economic fallout to the entire mining process, it is practically unavoidable due to the complex causing mechanism. In this study,the contribution of ten major UB causative parameters has been scrutinised based on a published UB predicting artificial neuron network(ANN) model to put UB under the engineering management. Two typical ANN sensitivity analysis methods, i.e., connection weight algorithm(CWA) and profile method(PM) have been applied. As a result of CWA and PM applications, adjusted Q rate(AQ) revealed as the most influential parameter to UB with contribution of 22.40% in CWA and 20.48% in PM respectively. The findings of this study can be used as an important reference in stope design, production, and reconciliation stages on underground stoping mine. | Jang Hyongdoo Topal Erkan Kawamura Youhei | 2016 | International Journal of Mining Science and Technology2016，26，6： | 2 |

| 8 | Designing an optimal stope layout for underground mining based on a heuristic algorithm显示文摘An optimal layout or three-dimensional spatial distribution of stopes guarantees the maximum profitability over life span of an underground mining operation.Thus,stope optimization is one of the key areas in underground mine planning practice.However,the computational complexity in developing an optimal stope layout has been a reason for limited availability of the algorithms offering solution to this problem.This article shares a new and efficient heuristic algorithm that considers a three-dimensional ore body model as an input,maximizes the economic value,and satisfies the physical mining and geotechnical constraints for generating an optimal stope layout.An implementation at a copper deposit demonstrates the applicability and robustness of the algorithm.A parallel processing based modification improving the performance of the original algorithm in terms of enormous computational time saving is also presented. | Sandanayake Don Suneth Sameera Topal Erkan Asad Mohammad Waqar Ali | 2015 | International Journal of Mining Science and Technology2015，25，5： | 2 |
