Growing aquarium fish on organic food objects

The dependence of the cultivation of predatory aquarium fish on the use of live food in the diet as an organic food object in the aquaterrarium of the Roev Ruchey Park in the city of Krasnoyarsk was studied. When choosing an organic food object for growing ornamental fish, guppies and swordtail fish of the Pecilia family were considered. Their diet consisted of a combination food and meat mix for freshwater fish. Swordtails gave offspring more than guppies by almost 2 times, puberty came 1 week earlier, the life cycle is longer by 2 years. Brilliant cichlazomas of the studied groups received a combined feed in the diet, the fish of the control group were additionally fed a meat mixture for freshwater fish, in the experimental group this mixture and part of the combined feed were replaced with organic food objects - swordtails in the amount of 0.75 g/head per day

ASTHMA PREVALENCE AND RISK FACTORS Morphological and Molecular Characteristics of "Difficult" Asthma

Background. There are several clinical variants of severe difficult-to-treat asthma: asthma with persistent airflow limitation, brittle asthma, and fatal asthma; but the differences between the pathogenetic mechanisms underlying the disease heterogeneity are unknown. Objectives. The aim was to evaluate the morphological and molecular characteristics of brittle asthma type I and asthma with persistent airflow limitation compared to mild-to-moderate asthma, by the analysis of the cellular structure and gene expression in the bronchial mucosa. Methods. Bronchoscopic evaluation was performed in 42 asthmatic patients: 10 with brittle asthma, 10 with severe asthma with persistent airflow limitation, and 22 with mild-to-moderate asthma. Morphometric and cytological analyses of the bronchial mucosa were performed. The mRNA levels for the ADRB2, HRH1, and CHRM3 genes in the bronchial mucosa were measured by quantitative real-time polymerase chain reaction (PC
