Role of von Willebrand factor levels in the prognosis of stage Ⅳ colorectal cancer: Do we have enough evidence?

World journal of Gastroenterology 2005年第38期11卷 6072-6073页

作者： I.Gil-Bazo j.a Díaz-González j.Rodríguez j.Cortés E.Calvo j. A. Páramo j.García-Foncillas Department of Oncology Institute for Drug Development Service of Haematology

Cancer patients usually present a prothrombotic condition. Several clotting-related proteins, such as von Willebrand factor （vWF）, presenting higher plasma concentrations in these patients, may play a key role in this process. Moreover, some of those proteins are currently being characterized as response rate and overall survival markers in metastatic colorectal cancer （MCRC）. In this comment article,

Thermal conductivity of soils with heavy metals concentration from the Niger Delta region of Nigeria

引用

journal of Zhej.ang University-Science B(Biomedicine & Biotechnology) 2006年第8期7卷 615-618页

作者： AKINYEMI O.D OLOWOFELA j.a AKINLADE O.O. AKANDE O.O. Department of Physics University of Agriculture AbeokutaPMB 2240Nigeria

This paper presents the characteristic thermal and chemical properties of some surface soil samples from the oil-producing regions of Nigeria. A microprocessor-based thermal analyzer was used to determine the thermal conductivity while spectrophotometric procedure was employed to conduct the heavy metal concentration analysis. Thermal conductivity values were compared with heavy metal concentrations in each soil sample. The values of lead and cadmium and their respective measured thermal conductivities were highly correlated, with their correlation coefficients both greater than 0.900, while other metals showed no correlation.

＜正＞ This work presents a model of economic assessment for irrigated lands in order to establish the possible compensatory allowances to the farmer for the, total or partial, withdrawal of the water use rights in over-exploited aquifers. This is one of the possible solutions considered in the Spanish Hydrologic National Plan （HNP, 2000） to solve the environmental problems caused in a surface of 16000 km2 named Upper Guadiana. The model analyzes the gross
