The Union of Nature and Conscience in F. Dostoevsky’s Novel “Crime and Punishment”

The article deals with the problem of conscience in the novel by F. Dostoevsky’s “Crime and Punishment”. The concept of conscience is analyzed in an indissoluble union with human nature

Computational chemistry of the silicon nitride surface. 2. Binary hydroxylamine complexes. Geometry and bond energies

In order to study the silicon nitride surface it is interesting to consider hydrogen-bonded complexes with hydroxyl and amine key groups (OH...O, OH...N, NH...O, and NH...N). To investigate the behavior of the above bonds, we considered the water, ammonia, and hydroxylamine dimers and the binary hydroxylamine complexes with water and ammonia. The results of this work are compared with the data obtained by an ab initio method. © 1996 Plenum Publishing Corporation

COMPUTATIONAL CHEMISTRY OF THE SILICON-NITRIDE SURFACE .1. WATER, AMMONIA, AND WATER-AMMONIA COMPLEX

This paper deals with computational modeling of structure and properties of the silicon nitride surface zone using combined computational and real experiments. The computational experiment implies quantum chemical calculations of structure and vibrational spectra of polyatomic clusters. The real experiment suggests measurement and analysis of vibrational spectra. For quantum chemical calculations, semiempirical methods (MNDO and AM1) were chosen. In most calculations, the MNDO/H method was preferred because of the presence of many H-bonds in the surface zone. For verification of calculations, we calculated the structures and vibrational spectra of water and ammonia molecules and the water-ammonia complex and compared the results with experimental and ab initio (extended basis) data; MNDO/H proved to be an optimal method giving reliable results

EFFICIENCY OF MONTELUKAST TREATMENT OF THE CHILDREN, SUFFERING FROM BRONCHIAL ASTHMA

The aim of the present open research was to assess the montelukast efficiency among 41 children, suffering from bronchial asthma. the age of patients was between 6 and 15 years old. Clinical and functional efficiency of montelukast was noted among 85,4% of the patients. montelukast treatment contributed to the decrease of the bronchial asthma recrudescence frequency, reduction of the number of the used betab2bprotoganists, inhaled glucocorticosteroids and increase of tolerance towards the physical load.Key words: bronchial asthma, montelukast, children, treatment

Bashlyaeva City Children Clinical Hospital, Moscow, Russian Federation Aim: to improve the efficacy of iron deficiency treatment in teenage girls by their early diagnosis and rational treatment. Patients and Methods: complete blood count was performed in 2,303 teenage schoolgirls aged 14–17 years (mean age 16.3±0.6 years) who underwent routine annual medical examination. Whole capillary blood was tested. Reduced hemoglobin concentration (less than 120 g/l) was anemia diagnostic criterion in teenage girls. Hypochromic anemia was verified in color index less than 0.85 and mean corpuscular hemoglobin (MCH) less than 26 pg. In some girls (n=133) with verified isolated hypochromic red blood cells but in the lack of anemia and microcytosis, serum iron, total iron-binding capacity, serum ferritin, and transferrin saturation were measured. Results: hypochromic anemia was diagnosed in 8.3% of teenage girls. In 96.8% of them, anemia was mild. In 133 teenage girls with verified hypochromic red blood cells but no anemia, latent iron deficiency was diagnosed in 20.3% of cases. Preliminary results of mild iron-deficiency anemia treatment in 19 teenage girls (mean age 14.7±0.5 years) using Tardyferon demonstrate its good tolerability and high clinical laboratory efficacy. After 4 weeks of the treatment, hemoglobin concentration has increased by 10.7±0.3 g/l (р&lt;0.05). No adverse side effects were reported. Conclusions: our findings demonstrate that the algorithm described in this paper should be followed to improve the diagnosis of iron deficiencies. Keywords: anemia, hypochromic RBCs, teenage, iron deficiencies, iron-deficiency anemia, latent iron deficiency, iron preparations, Tardyferon.
