Thermographic study of the reaction of copper, zinc, nickel, and lead selenites with sodium carbonate: Thermographic study of the reaction of copper, zinc, nickel, and lead selenites with sodium carbonate. Muldagalieva, R. A.; Pashinkin, A. S.; Makhmetov, M. Zh.; Malyshev, V. P. (Khim.-Metall. Inst., Karaganda, USSR). Deposited Doc., VINITI 3722-75, 12 pp. Avail. VINITI (Russian) 1975. DOCUMENT TYPE: Report CA Section: 54 (Extractive Metallurgy) The reaction mechanism of CuSeO3 [16509-17-4], CuO×CuSeO3 [15599-88-9], ZnSeO3 [13597-46-1], NiSeO3 [10101-96-9], and PbSeO3 [7488-51-9] with Na2CO3 was investigated. Cu selenite reaction with Na2CO3 began at 130 and ended at 430°. The wt. loss in 20 min at 450° of ~10% indicated formation of Na2SeO3 [10102-18-8].

Activation of lipid peroxidation in the liver during hypokinesia and its prevention by antioxidants: Activation of lipid peroxidation in the liver during hypokinesia and its prevention by antioxidants. Panasyuk, E. N.; Skakun, L. N. (USSR). Kosm. Biol. Aviakosm. Med., 19(1), 48-52 (Russian) 1985. CODEN: KBAMAJ. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacology) Section cross-reference(s): 18 In rats subjected to 4-30 days of hypokinesia, peroxidn. of cell-membrane unsatd. fatty acids increased in the liver, as well as the no. of disulfide groups. This was most marked during the stress-response period (4-7 days), the rate of free-radical processes declining slightly thereafter. After termination of 7-day hypokinesia, lipid peroxidn. rates returned to normal. S.c. or i.m. administration of antioxidants such as syrepar [11095-03-7] (0.1 mL/0.1 kg), a-tocopherol acetate [58-95-7] (5 mg/0.1 kg), or sodium selenite [10102-18-8] (3 mg/0.1 kg) blocked the initiation of free-radical reactions.
