BACKGROUND Primary liver cancer is common in West Africa due to endemic risk ***,epidemiological studies of the global burden and trends of liver cancer are *** report changes in trends of the incidence of liver cancer over a period of 28 years using the population-based cancer registry of Bamako,*** assess the trends and patterns of liver cancer by gender and age groups by analyzing the cancer registration data accumulated over 28 years(1987-2015)of activity of the population-based registry of the Bamako *** Data obtained since the inception of the registry in 1987 through 2015 were stratified into three periods(1987-1996,1997-2006,and 2007-2015).Age-standardized rates were estimated by direct standardization using the world *** rate ratios and the corresponding 95%confidence intervals(CI)were estimated using the early period as the reference(1987-1996).Joinpoint regression models were used to assess the annual percentage change and highlight trends over the entire period(from 1987 to 2015).REsULTs Among males,the age-standardized incidence rates significantly decreased from 19.41(1987-1996)to 13.12(1997-2006)to 8.15(2007-2015)per 105 *** incidence rate ratio over 28 years was 0.42(95%CI:0.34-0.50),and the annual percentage change was-4.59[95%CI:(-6.4)-(-2.7)].Among females,rates dropped continuously from 7.02(1987-1996)to 2.57(2007-2015)per 105 person-years,with an incidence rate ratio of 0.37(95%CI:0.28-0.45)and an annual percentage change of-5.63[95%CI:(-8.9)-(-2.3)].CONCLUsION The population-based registration showed that the incidence of primary liver cancer has steadily decreased in the Bamako district over 28 *** trend does not appear to result from biases or changes in registration *** is the first report of such a decrease in an area of high incidence of liver cancer in *** decrease may be explained by the changes and diversity of diet that could reduce exposure to

碳纳米管纱(CNTY)因具有优异的力学强度、化学稳定性、热稳定性和高比表面积而成为去除废水中有机污染物的潜在材料。本文将CNTY用于含2,4-二硝基甲苯(DNT)的污水处理。CNTY对DNT的吸附能力与文献报道值作对比研究,同时探讨吸附动力学。采用sEM-EDX、HRTEM、Raman与XPs表征CNTY吸附DNT前后的尺寸、表面形貌及表面化学。结果表明,经CNTY对DNT污水处理后的水质达到实验室无离子水级纯度。CNTY对DNT吸附符合Freundlich吸附等温线,Freundlich参数由K/nF为55.0 mg/g(L/mg)1,指数1/n为0.737得到,表明其比活性炭吸附性弱,但更易再生。CNTY比活性炭的吸附性速率更快,遵循拟二级动力学模型。CNTY吸附DNT引起D、G常偏移,归因于CNTs与DNT间电子受体和供体效应。

Geochemical and Geostatistical tools were used to assess: 1) the chemical quality and, geochemical processes in crystalline rock aquifers in sabodala (Eastern senegal) and its surroundings and 2) the impact of mining activities on their quality. A total of 26 water samples collected at boreholes, dug wells and stream, were analyzed to determine major and trace elements concentration focused on elements that represent more threats on human health. Boxplots define chemical characteristics of water for each aquifer formation compared to surface waters. Geostatistical analysis show two sources of water mineralization with regard to major elements: a first natural source characterized by Ca-Mg-HCO3 water type from boreholes and unpolluted surface water and a second group characterized by polluted water by nitrates with Na-NO3-Cl type mainly observed in upper weathered aquifers. However, considering trace element, geostatistical analysis showed three water groups: water with very low trace element concentrations encountered in boreholes and unpolluted surface waters, and waters with relatively high trace element concentrations such as Al observed in areas affected by gold mining activities and finally, polluted waters by Ni, Co, Mn and Cr observed at sabodala. Results show that in eastern senegal well waters are vulnerable and often affected by pollution.

Mycoplasma mycoides subsp. capri is the causative agent of severe and acute respiratory problems in goats, which spreads rapidly and represents high mortality. The serological profile of the goat population, from nine regions in seven states of Mexico, was screened by the Complement Fixation test (CF) in sera from asymptomatic goats and animals with mild respiratory symptoms. sera and nasal swabs of 827 goats were collected for the isolation of the organism. An antiserum was prepared against a previously isolated field strain of Mycoplasma mycoides subsp. capri. CF Antibody titers were associated with the results of the isolates to determine the cutoff point. The CF was considered as positive if its result was ≥1/16. The CF registered 251 positive goats (30.35%) and 576 (69.65%) negative;the test showed high sensitivity (93.33%) and specificity (72.27%). In the specific case of diagnosis for mycoplasmosis associated with respiratory problems in goats, the CF proved to be a good diagnosis test, this study determined that 30% of the goat population showed antibody titers against Mycoplasma mycoides subsp. capri and revealed those animals who have had contact with this microorganism during their lives regardless of the presence or absence of respiratory symptoms.
