[Potter sequence in a newborn with polycystic kidney disease].

A rare clinical case of a newborn boy with a diagnosed Potter sequence is presented. The diagnosis was made based on polycystic dysplasia of the kidneys, cysts in the liver, hypoplasia of the lungs and characteristic external signs due to critical oligohydramnios. The child's parents were closely related, which suggested an autosomal recessive form of the disease.

In Silico Predictions on the Productive Life Span and Theory of Its Developmental Origin in Dairy Cows.

Animal welfare includes health but also concerns the need for natural factors that contribute to the increase in viability. Therefore, quantitative parameters are necessary to predict the risks of early culling of cows. In the study of the age dynamics of the disposal rate (culling for sum of reasons + death) in dairy cow populations, it was found that the average productive life span can be predicted by the value of the reciprocal culling/death rate (reciprocal value of Gompertz function) at the first lactation.

The Processes of Nutrition and Metabolism Affecting the Biosynthesis of Milk Components and Vitality of Cows with High- and Low-Fat Milk.

In order to clarify the mechanism of the depression of milk fat formation and preserve the health of animals, the aim of the research was to study the characteristics of rumen digestion, energy metabolism, and milk composition in high-producing dairy cows with high and low levels of milk fat that are fed the same diet. Two groups of cows with normal milk fat content (3.94 ± 0.

Communicating artificial neural networks develop efficient color-naming systems.

Words categorize the semantic fields they refer to in ways that maximize communication accuracy while minimizing complexity. Focusing on the well-studied color domain, we show that artificial neural networks trained with deep-learning techniques to play a discrimination game develop communication systems whose distribution on the accuracy/complexity plane closely matches that of human languages. The observed variation among emergent color-naming systems is explained by different degrees of discriminative need, of the sort that might also characterize different human communities.

[Creation of Blast Disease-Resistant Rice Sorts with Modern DNA-Markers].

Based on modern technologies of molecular DNA-markers, blast disease-resistance genes (Pi-ta, Pi-b, Pi-1, Pi-2, and Pi-33) were introgressed and pyramided into domestic rice varieties to give them long-term disease resistance. For that purpose, this case study uses SSR-markers closely linked to these genes, as well as intragenic markers of genes Pi-ta and Pi-b. Multiplex PCR systems were created for simultaneous identification of two resistance genes in the hybrid progeny for the following combinations: Pi-1 + Pi-2, Pi-ta + Pi-b, Pi-ta + Pi-33.
