Fragmentation of Single-Particle Strength around the Doubly Magic Nucleus

Spectroscopic factors of neutron-hole and proton-hole states in ^{131}Sn and ^{131}In, respectively, were measured using one-nucleon removal reactions from doubly magic ^{132}Sn at relativistic energies. For ^{131}In, a 2910(50)-keV γ ray was observed for the first time and tentatively assigned to a decay from a 5/2^{-} state at 3275(50) keV to the known 1/2^{-} level at 365 keV. The spectroscopic factors determined for this new excited state and three other single-hole states provide first evidence for a strong fragmentation of single-hole strength in ^{131}Sn and ^{131}In. The experimental results are compared to theoretical calculations based on the relativistic particle-vibration coupling model and to experimental information for single-hole states in the stable doubly magic nucleus ^{208}Pb.

[Effectiveness of the use of iodized milk protein to improve girls' sufficiency with iodine].

The work presents the results of the research capabilities of the use of iodized milk protein as a component of food supplement and enriched food product for the correction of iodine sufficiency in girls. Milk iodinated protein was produced by the enzyme-effective iodization of amino acid residues of cow's milk whey proteins. The study involved 30 girls, whose average age was 19.9 +/- 1.4 years. Participants of observation were divided into three groups, for 10 people each. The first group received daily serving of meat cutlets (50g), enriched with dairy iodinated protein. Iodine content in the finished minced was 100 mcg. The second group received iodinated milk protein in the form of food supplement with iodine content of 100 mcg. The third group was a control one. The duration of observations was 30 days. To assess the effectiveness of measures the concentration of iodine in urine, blood levels of thyroid-stimulating hormone and free thyroxine have been determined, changes in cognitive processes (memory and attention) with the use of psychological tests have been evaluated. Studies have shown the effectiveness of using of iodized milk protein for the correction of iodine deficiency in girls. The use of iodized protein, as part of the enriched product and in the form of food supplement increased urinary iodine level and had a positive influence on the state of the hypophysial-thyroid system. In addition, the use of iodized milk protein helped to improve the cognitive functions of the students, which can be considered as an additional positive effect of correction of iodine deficiency.

[Evaluation of the effect of a medical-prophylactic product "Solnyshko" on the vitamin status in humans]. / Otsenka vliianiia lechebno-profilakticheskogo produkta "Solnyshko" na vitaminnyi status cheloveka.

The results of use of a treatment-and-prophylactic product "Solnyshko" in people's food as well as pharmacological preparations containing b-carotene and ascorbic acid were submitted. It was shown that at the use of the specified product and pharmacological preparations there is an authentic improvement of b-carotene and ascorbic acid supply.

Effects of beta-carotene and aspartame on clustogenic activity of cyclophosphamide and dioxidine in mice.

Antimutagenic effects of combination of aspartame (0.4 and 4 mg/kg) and beta-carotene (0.15-15 mg/kg) were studied by estimation of chromosome aberrations in bone marrow cells of C57Bl/6 mice. Single and 5-day treatment with this combination decreased the clastogenic effects of dioxidine and cyclophosphamide and produced a more potent and universal antimutagenic effect than its constituents.

[Clinico-rheoencephalographic characteristics of the cerebral form of neurocirculatory dystonia]. / Kliniko-reoentsefalograficheskaia kharakteristika tserebral'noi formy neirotsirkuliatornoi distonii.

The study is related to a clinical and REG study of 387 patients with cerebral forms of neurocirculatory dystonia, proceeding against the background of normal, increased and decreased arterial pressure. These studies were performed in order to clarify the question of the state of cerebral hemodynamics in this form of vascular pathology. The study detected some general regularities of the changes of cerebral hemodynamics (an increase of the cerebral vascular tone, difficulties of the venous outflow, signs of vascular dystonia in the form of unstable curves and intrahemispheric asymmetry) and some traits in different types of neurocirculatory dystonia as well as some traits of semiotics.
