The Effects of Melatonin and L-DOPA on the Diurnal Rhythms of Free Amino Acids Content in the Rat Retina

Autor: R. N. Etingof, E. M. Doroshenko, E. V. Lavrikova, Nikita Pozdeyev

Publikováno v: Journal of Biological Rhythms. 15:112-121

The effects of melatonin and dopamine precursor L-3,4-dihydroxyphenylalanine (L-DOPA) intraperitoneal administration on the rhythms of free amino acids content in the retina of rats were studied. The authors found that the levels of those amino acids

Biosynthesis of melatonin during early postnatal ontogeny in pineal gland of healthy rats and animals with hereditary retinal degeneration

Autor: R. N. Etingof, N. V. Pozdeev

Publikováno v: Bulletin of Experimental Biology and Medicine. 123:110-113

The content of melatonin and its precursors in the pineal gland of healthy rats and rats with hereditary retinal degeneration is studied on days 20 and 40 of postnatal development. The measurements are performed between 02:30 and 03:00, when the cont

Purine biosynthesis de novo in bovine retina: purification and characterization of amidophosphoribosyl transferase and phosphoribosyl pyrophosphate synthetase

Autor: I A, Kian, R N, Etingof

Publikováno v: Biochemistry. Biokhimiia. 64(6)

The ability of bovine retina to synthesize purines de novo is shown for the first time. Amidophosphoribosyl transferase (EC 2.4.2.14), the enzyme controlling the rate of the process, and phosphoribosyl pyrophosphate synthetase (EC 2.7.6.1), the enzym

[Decreased content of non-heme iron in the blood of patients with peripheral tapetoretinal abiotrophy]

Autor: N V, Pozdeev, M V, Volkova, M G, Efimova, Iu S, Astakhov, R N, Etingof

Publikováno v: Vestnik oftalmologii. 114(3)

Measurement of non-heme iron in the sera of patients with peripheral tapetoretinal abiotrophy aged 10-72 years with stages I-IV of the disease showed a statistically significant (26-30%) decrease of this parameter in comparison with healthy controls.
