Caenorhabditis elegans (C. elegans), with homologous genes and conservative spermiogenesis in mammals, has a series of advantages to illuminate and study many biological processes including reproductive toxicity. So it is a very useful model to assess environmental and ecological toxicity. Here we introduce C. elegans as an animal model and three known mammalian sperm teratogens methyl methanesulfonate,...
In this paper, thermal expansion coefficients of 42 pure metallic elements were evaluated on the basis of empirical and theoretical methods and the adjusted Debye–Grüneisen model. In Debye–Grüneisen model, Debye temperature was regarded as an undetermined constant. Parameters in the model were determined via the nonlinear least square fit method through MATLAB program. Besides, for pure metallic elements...
