[Morphological features of an optic nerve in premature infants according to the optical coherence tomography data].

Objective: To assess the morphological state of the visual analyzer in premature infants in long-term.

Material And Methods: We examined 40 premature children (74 eyes) aged 10.3±2.

[Anatomo-functional state of the central retina in premature infants with intraventricular hemorrhage and retinopathy of prematurity].

Objective: Assessment of the anatomo-functional state of the central retina in children with intraventricular hemorrhage (IVH) and retinopathy of prematurity (ROP) in the long-term period.

Material And Methods: We examined 51 patients (102 eyes) born 25-34 weeks' of gestation (birth weight 700-2290 g), aged 8.83±3.

[Modern possibilities of diagnosing lesions of the visual analyzer in perinatal lesions of the central nervous system in full-term and premature infants].

The article provides an overview of current neuro-ophthalmological diagnostic capabilities in patients with perinatal lesions. The main attention is paid to the diagnosis of patients with periventricular leukomalacia and peri- and intraventricular hemorrhages. The most relevant methods of neuro-ophthalmological diagnosis in hypoxic-ischemic CNS lesions are covered.

Assessment of the variability of reproductive abilities of a black and white cattle using genealogical data and paratypical factors.

The purpose of this study was to assess the role of paratypical and genetic factors in the variation of the complex of traits associated with the reproductive quality of livestock in the conditions of the CJSC breed livestock factory farm "Irmen" in a retrospective aspect. Black-and-White Irmenskiy interbreeds type breed was officially registered in 2000 by the Ministry of Agriculture of the Russian Federation as a breeding achievement and is a unique cattle subpopulation, bred only at the Irmen breed livestock factory farm, in Western Siberia, (Russia). This type is the best in all of Western Siberia in terms of milk yield and appearance among annual competitions and official state assessments.

[Genetics of ketosis resistance in cattle].

The frequency of ketosis among the Black-pied cattle in western Siberia have been determined. The genotype of sires and genetic composition of lines were shown to affect resistance and susceptibility to ketosis. The heritability of resistance to the disease was 0.
