A new complex plant for carbonization and composting of municipal wastes

引用

Particuology 2010年第6期8卷 599-601页

作者： Shigekatsu mori Nagoya University 2-17-4 MinamigaokaNishinAichi 470-0114Japan

A new complex plant for carbonization and composting of municipal wastes proposed for Gero City is introduced. The separated combustible waste and non-separated combustible waste are carbonized in two fluidized carbonization furnaces in the plant, and the coke produced is used in steelworks. The separated garbage and forest-wastes are mixed with dried septic-tank sludge to produce high quality compost for farms. This use of waste materials in the complex plant considerably lowers the amount of waste going to land-fills, and in addition, creates lower total emission of dioxins and carbon dioxide into the environment.

Shortening of alkaline DNA unwinding time does not interfere with detecting DNA damage to mouse and human spermatozoa in the comet assay

引用

Asian Journal of Andrology 2011年第1期13卷 172-174页

作者： hirokazu Kusakabe Hiroyuki Tateno Department of Biological Sciences Asahikawa Medical University Asahikawa 078-8510 Japan

The comet assay was performed on mouse and human spermatozoa to examine the effect of alkaline DNA unwinding time. The spermatozoa were treated in vitrowith the DNA-damaging agents, methyl methanesulfonate （MMS） or hydrogen peroxide （Hz02）, and then embedded in agarose gel on glass sl ides. The slides were immersed in alkaline solution （〉pH 13） for 1, 5, 10 and 20 min, and then subjected to the electrophoresis under neutral conditions. In mouse spermatozoa, comet tails seen in solvent controls became brighter and longer as the alkaline DNA unwinding time increased. However, in the MMS-treated mouse spermatozoa, a smaller difference in the damage from that in the solvent control was seen with time within a dose. DNA damage induced by H2O2 could also be detected accurately after alkali treatment for 1-20 min. In human spermatozoa, DNA damage induced by MMS and H2O2 could be detected in a dose-dependent manner after alkali treatment for 1 min. The ability of the comet assay to detect DNA damage was not adversely affected by the short period （1 min） of the alkaline DNA unwinding time.
