Our laboratory has been examining the mechanisms whereby chemicals are mutagenic in short-term in-vitro assays yet are not carcinogenic in 2-year rodent bioassays. Previous studies indicated that mutagenic carcinogens increased the amount of cell turnover in the target organ, but that mutagenic noncarcinogens failed to do so. The present study compares the incidence of cell proliferation in spe...

abstract gatan has distributed in the main rivers in khoozestan province and there are few researches on propagation and reproductive system of this species. therefore, this study has focused on using of activating solutions on sperm activity and fertilization capability in gatan fish in comparison with grass carp. in this research, 5 activating solutions together with workshop water and distil...

In the title compound, 3[(CH(3))(3)HN(+)]·3C(3)H(2)N(3)S(3) (-)·H(2)O, two independent trithio-cyanurate anions construct a planar hydrogen-bonded ribbon with two N-H⋯S hydrogen bonds linking each pair of adjacent anions in the chain. The third independent anion and the water mol-ecule form a chain by way of N-H⋯S and O-H⋯S contacts, which propagates parallel to the ribbon. The chains and ribbo...

In the title compound, C(21)H(21)O(3)P, the whole mol-ecule is disordered over two sets of positions with refined occupancies of 0.503 (1) and 0.497 (1). The dihedral angles between the three benzene rings are 72.9 (2)°, 82.9 (3)° and 70.0 (2)° in the major disorder component and the corresponding angles in the minor disorder component are 85.0 (2)°, 79.2 (2)° and 72.3 (2)°. The crystal structu...
