DIOXIN INDUCES GENOMIC INSTABILITY IN MOUSE EMBRYONIC FIBROBLASTS.

Ionizing radiation and certain other exposures have been shown to induce genomic instability (GI), i.e., delayed genetic damage observed many cell generations later in the progeny of the exposed cells.The aim of this study was to investigate induction of GI by a nongenotoxic carcinogen, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD).Mouse embryonic fib

Recent studies demonstrate that the reproduction of prey is suppressed by the fear of predators.However, it will not respond Health immediately to fear, but rather reduce after a time lag.We propose a diffusive predator-prey model incorporating fear response delay into prey reproduction.Detailed bifurcation analysis reveals that there are three dif
