[Phylogenetic analysis of Altai osmans of the genus Oreoleuciscus (Pisces, Cyprinidae, Leuciscinae), based on the analysis of the cytochrome oxidase 1 gene (Co-1) sequence].

Molecular genetic analysis of Altai osmans of the genus Oreoleuciscus from two different parts of the range was carried out. In this study, based on the mitochondrial Co-1 gene sequence, a total of 25 fish specimens belonging to four genera were examined: (1) O. humilis, 2 specimens; O.

[The regularities in connection between fecundity with body weight and growth rate in fishes].

The absolute and relative fecundity of freshwater, anadromous and marine fishes (102 species and subspecies from 33 families) and its dependence on body mass and growth rate were analyzed on the basis of published data. According to the spawning type all studied fishes were divided into species with short-term and single spawning and fishes with extended or long-term spawning. The equations of dependence of absolute fecundity (E) on body mass (W) were calculated: E = 1.

[The assessment of the efficacy of calcium antagonists in the treatment of children with repeated episodes of the broncho-obstructive syndrome].

Overall seventy-five schoolchildren with a history of no less than 4 episodes of impassability commonly against the afebrile background were examined. The results obtained suggest that the greatest reduction in the relative risk of bronchial unspecific hyperreactivity manifestations with calcium antagonists being ingested occurs in those children experiencing recurrent episodes of bronchial obstruction in the presence of marked lability of the bronchi that is commonly associated with the atopic genesis of their obstruction.
