Overview of clinical trials for nasopharyngeal carcinoma(in the English literature)

引用

Chinese Journal of Cancer 2010年第8期29卷 709-714页

作者： anne W.M.Lee Department of Clinical Oncology Pamela Youde Nethersole Eastern Hospital

Megavoltage radiation therapy (RT) is the primary treatment modality for nasopharyngeal carcinoma (NPC). Treatment results have been steadily improving with rapid technological advances and better knowledge on optimization of dose fractionation. During the past decade, RT techniques have evolved from conventional 2-dimensional (2D) to 3-dimensional (3D) complex technique with multiple conformal fields and intensity-modulation. There is little controversy that intensity-modulated technique (IMRT) is recommended if resources permit, dosimetric studies show clear improvement in dose distribution, with conformity of high dose to concave tumor targets and sharp dose gradient for adequate tumor coverage and better protection of adjacent normal tissues.

To summarise the literature data on hepatitis C virus (HCV)-infected patients concerning the prevalence of glucose abnormalities and associated *** conducted a PubMed search and selected all studies found with the key words 'HCV' or 'hepatitis C virus' and 'diabetes' or 'insulin resistance'. We included only comparative studies written in English or in French, published from January 2000 to April 2015. We collected the literature data on HCV-infected patients concerning the prevalence of glucose abnormalities [diabetes mellitus (DM) and insulin resistance (IR)] and associated risk [i.e., severe liver fibrosis, response to antivirals, and the occurrence of hepatocellular carcinoma (HCC)].RESULTSHCV infection is significantly associated with DM/IR compared with healthy volunteers and patients with hepatitis B virus infection. Glucose abnormalities were associated with advanced liver fibrosis, lack of sustained virologic response to interferon alfa-based treatment and with a higher risk of HCC development. As new antiviral therapies may offer a cure for HCV infection, such data should be taken into account, from a therapeutic and preventive point of view, for liver and non-liver consequences of HCV disease. The efficacy of antidiabetic treatment in improving the response to antiviral treatment and in decreasing the risk of HCC has been reported by some studies but not by others. Thus, the effects of glucose abnormalities correction in reducing liver events need further *** abnormalities are strongly associated with HCV infection and show a negative impact on the main liver related outcomes.

Optimal machining conditions for turning Ti-6Al-4V using response surface methodology

引用

Advances in Manufacturing 2013年第4期1卷 329-339页

作者： Satyanarayana Kosaraju Venu Gopal anne Department of Mechanical Engineering National Institute of TechnologyWarangal

Machining titanium is one of ever-increasing magnitude problems due to its characteristics such as low thermal conductivity, modulus of elasticity and work hardening. The efficient titanium alloy machining involves a proper selection of process parameters to minimize the tangential force （Fz） and surface roughness （Ra）. In the present work, the performance of PVD/TiA1N coated carbide inserts was investigated using response surface methodology （RSM） for turning Ti-6A1-4V. The effects of process parameters such as speed （v）, feed （/＇）, depth of cut （d） and back rake angle （Ty） on Fz and Ra were investi- gated. The experimental plan used for four factors and three levels was designed based on face centered, central composite design （CCD）. The experimental results indi- cated that Fz increased with the increase in d, f and decreased with the increase in v and yy, whereas Ra decreased with the increase in v and 7y, and increased with d and v. The goodness of fit of the regression equations and model fits （R2） for Fz and Ra were found to be 0.968 and 0.970, which demonstrated that it was an effective model. A confirmation test was also conducted in order to verify the correctness of the model.

Success of three soil restoration techniques on seedling survival and growth of three plant species in the Sahel of Burkina Faso(West Africa)

引用

Journal of Forestry Research 2016年第2期27卷 313-320页

作者： Philippe Bayen anne Mette Lykke Adjima Thiombiano Laboratory of Plant Biology and Ecology University of Ouagadougou Department of Bioscience Aarhus University

In the Sahel of Africa, where 90 % of the population depends on natural resources for their liveli- hood, a large part of the soils are structurally unstable, prone to crusting and hard setting, and have low water holding capacity, which hamper vegetation establishment. The effect of soil restoration techniques on survival and growth of seedlings of Acacia nilotica, Acacia tortilis and Jatropha curcas was tested in completely barren, degraded land in a Sahelian ecosystem in Burkina Faso. A total of 522 seedlings （174 plants of each plant species） were planted in a randomized complete block design with three replicates combining three soil preparation techniques： half-moon, zai＂ and standard plantation. Survival and growth rates evaluated over 20 months were significantly higher using the half-moon technique compared with the other two techniques. Survival rates of plant species planted using half-moon technique were 62.5, 28.57 and 10.71% for A. nilotica, A. tortilis and J. curcas respec- tively, but in za＇i and standard planting, seedling survival was zero. The low survival rate of J. curcas using the half-moon technique may indicate that J. curcas is unsuit- able for barren and degraded land, whereas A. nilotica and A. tortilis appear to be promising tree species for rehabil- itation of degraded land.
