Glyphosate is a broad-spectr.m herbicide originally introduced to the market in 1974 by the agrochemical company monsanto. more than 40 years down the line, glyphosate has become one of the most economically meaningful herbicides, with a global use of more than 1.8 million pounds in 2014 (Benbrook, 2016). In non resistant plants, glyphosate is widely believed to exert its herbicidal effect via inhibition of the 5-enolpyruvylshikimate-3-phosphate synthase, an enzyme of the shikimate pathway required for the biosynthesis of ar.matic amino acids in plants and most microorganisms such as fungi, bacteria and some protozoans.

The construction of the Three Gorges Dam on the Yangtze river has extensive impact on the ecosystems and the population of the Three Gorges Area （TGA）. Inundation and resettlement have induced far-reaching land use and land cover change （LUCC）. The areas that are affected by measures of resettlement are in a tense situation between the implementation of various gover.mental tasks addressing sustainable land use and water retention and the fulfilment of the population＇s economic needs, which pr.marily depend on agricultural production. Destabilization of slopes and soil erosion are immediate hazards induced by the impoundment. Farming is a very important source of income and has to persist on the one hand to assure the income of the rural population. On the other hand, the environment has to be protected fr.m runoff, soil erosion and instabilities connected to relief, geology and hydraulic influences. In this study, supervised classifications are performed using Landsat-Tm （1987 and 2007） and ASTEr （2007） images. LUCC is assessed by post-classification change analysis. On the catchment scale, arable land has decreased significantly, while garden land （citrus orchards） and woodland have increased. LUCC mainly affects the area surrounding the reservoir （＂backwater＂） of the Xiangxi （香溪） river, driven by local resettlement, newly built infrastructure, relocation of land cultivation, and conversion of arable land to garden land. In the hinterland, LUCC occurs in form of abandonment of land cultivation as a consequence of the Grain-forGreen progr.mme.

Patients with inflammatory bowel disease have normal life expectancy and, due to modern immunosuppressive therapies, also a normal quality of life. Since mostly young people are affected, their social behaviour suits this environment. Alcohol binging is an increasingly disturbing factor among young people. We describe a patient with Crohn's disease, treated with azathioprine, who developed peliosis hepatis after three epsiodes of alcohol binging. Liver toxicity was not observed previously during the course of the treatment. Azathioprine-induced peliosis hepatis is thought to be idiosyncratic in humans. Fr.m animal studies, however, it is clear that hepatic depletion of glutathione leads to azathioprine toxicity to the sinusoidal endothelial cells. Damage of these cells causes peliosis hepatis. Since alcohol binging leads to hepatic glutathione depletion, we conclude that in our patient the episodes of binging have reduced liver gluathione content and therefore this has increased azathioprine toxicity causing peliosis hepatis. The problem of alcohol binging has not yet been addressed in IBD patients undertaking immunosuppressive therapy. This should be reviewed in future considerations regarding patients advice.

在最近几年中,影响铁路公司和为其提供机车车辆的铁路工业的市场环境正在发生根本性变化。供货方出现了相对集中的局面,Alstom、Bombardier、Siemens三巨头已经开始统治全球市场。其他小型供货商则主要提供专用产品。与此同时,需求方也发生了变化,先前的国有铁路公司不再享有20多年前为它们提供的资金来源。此外,租赁公司的重要性也日趋明显。
