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...

The effect of extraction buffer on extractable calpain and calpastatin activity in postmortem muscles was examined. Muscles were removed from ovine carcasses 24 h after slaughter and extracted with three volumes of two extraction buffers containing 20 (pH 7.5) and 100 (pH 8.3) mM Tris. There was a significant difference in pH of the muscle homogenates, having a pH of 5.84 and 7.58 for 20 and 10...

A flame retardant used in children's sleepwear, tris-(1,3-dichloro-2-propyl)phosphate (Fyrol FR2) is a mutagen in the Salmonella-mammalian tissue homogenate test after it has been activated by mouse or rat liver homogenate. The expected enzymatic hydrolysis product, 1,3-dichloro-2-propanol, is similarly a mutagen after activation by liver homogenate. A proposed metabolite of the flame retardant...
