[Formation of probabilistic structure of motor behavior in bottlenose dolphins in captivity].

A probabilistic structure of the motor behavior was analyzed in dolphin calves Tursiops truncatus in the prenatal period and adult dolphins in an oceanarium. Ethograms were recorded and subjected to a computer analysis. Ranking probabilities of transitions between behavioral acts revealed a highly determined sequence of operations underlying the newborn dolphins' behavior.

[Diagnosis of left-ventricular diastolic dysfunction in patients with predialysis chronic renal failure].

Aim: To specify effectiveness of different methods for assessment of diastolic function in patients with pre-dialysis chronic renal failure (CRF).

Material And Methods: Forty non-diabetic pre-dialysis CRF patients (20 males and 20 females, mean age 51 +/- 11 years) were studied. Serum creatinine was 209.

[Use of ceramic endoprostheses in reconstructive surgery of the lower jaw in children].

The work analyses the possibility to use individually prepared ceramic endoprostheses in 6 children with a congenital or acquired pathology of the mandible. The operative methods with the application of ceramic endoprostheses are described which are characterized by less traumatic action and higher accuracy of correcting the defect or deformity of the mandible as compared with using biological plastic materials. This method of treatment can be recommended at the intermediate stages of the restorative reconstruction treatment of the mandible pathology in children.

[Impact of day-to-day arterial pressure variability on the left ventricle geometry in patients with predialysis chronic kidney insufficiency].

Aim: To estimate the impact of day-to-day variability of blood pressure (BP) on left ventricular geometry in pre-dialysis patients.

Material And Methods: We estimate the impact of day-to-day variability of BP on left ventricular geometry in 42 non-diabetic pre-dialysis patients (22 F, 20 M, mean age 47 +/- 12 years) with arterial hypertension (> 140 and 90 mm Hg). Serum creatinine was 286.

[Effects of arterial compliance on geometry of the left ventricle in patients with pre-dialysis chronic renal failure].

To examine relationships between left ventricular geometry and general arterial compliance (GAC) in patients with predialysis chronic renal failure (CRF). 102 patients with predialysis CRF unrelated to diabetes mellitus (males 46, females 56, mean age 49.1 +/- 18.
