Biochemical muscle composition of rainbow trout twoyears bions from population of «Bogushevski» fish farm

The paper provides the data on biochemical composition (content of dry substance), moisture, fat, protein and minerals in the muscles of two years bions of trout. There is described the variability of the said indicators of the representative sampling, there is shown the comparison of the data obtained with rated standards. Using Spearmen’s rank order correlation there was ascertained the interrelation of some biochemical indicators with fish mass and Foolton’s coefficients of condition.В статье представлены данные по биохимическому составу (содержанию сухого вещества), влаги, жира, протеина и минеральных веществ мышцах двухлетков форели. Дана характеристика изменчивости указанных показателей репрезентативной выборки, проведено сравнение полученных данных с нормативными показателями. С помощью коэффициента ранговой корреляции Спирмэна установлена взаимосвязь некоторых биохимических показателей с массой рыбы и коэффициентами упитанности Фультона

Morphometrical indicators of trout underyearlings of various origin

There is provided a description of exterior morphometrical properties of trout underyearlings taken from two populations imported from the Russian Federation and France at the phase of impregnated row. There were discovered the differences between the underyearlings of various origin in terms of absolute and relative properties.Представлена характеристика экстерьерных морфометрических признаков сеголетков форели из двух популяций, завезенных на стадии оплодотворенной икры из России и Франции. Установлены различия сеголетков разного происхождения по ряду абсолютных и относительных признаков

Comparison characteristics of interior properties of Belarussian trout breeding Populations replacement

There were presented the comparison results of relative weights of trout females and males body parts from two populations adapted to the conditions of Belarus generated from the genetic material imported to Belarus.Представлены результаты сравнения относительных масс частей тела самок и самцов форели из двух популяций, адаптированных к условиям Беларуси, сформированных из завезенного в республику генетического материала

Reproductive properties сharacteristics of trout spawners from Belarussian genetic pool

It was ascertained that the brood material of rainbow trout available in the Republic of Belarus represents the valuable genetic material adapted to the conditions of fish breeding farms of Belarus quite capable of producing proper offspring. There are defined reproductive properties of selected ensemble (25 females) of rainbow trout. There was ascertained the correlation dependence between a female body weight and its industrial fecundity.Определено, что имеющийся в республике племенной материал радужной форели представляет собой ценный генетический материал, прошедший адаптацию к условиям рыбоводных хозяйств Беларуси, способный давать полноценное потомство. Дана характеристика воспроизводительных качеств выборочной совокупности (25 самок) радужной форели. Установлена корреляционная зависимость между массой тела самки и ее рабочей плодовитостью

Novel Copper-Containing Cytotoxic Agents Based on 2-Thioxoimidazolones

A series of 73 ligands and 73 of their Cu+2 and Cu+1 copper complexes with different geometries, oxidation states of the metal, and redox activities were synthesized and characterized. The aim of the study was to establish the structure-activity relationship within a series of analogues with different substituents at the N(3) position, which govern the redox potentials of the Cu+2/Cu+1 redox couples, ROS generation ability, and intracellular accumulation. Possible cytotoxicity mechanisms, such as DNA damage, DNA intercalation, telomerase inhibition, and apoptosis induction, have been investigated. ROS formation in MCF-7 cells and three-dimensional (3D) spheroids was proven using the Pt-nanoelectrode. Drug accumulation and ROS formation at 40-60 μm spheroid depths were found to be the key factors for the drug efficacy in the 3D tumor model, governed by the Cu+2/Cu+1 redox potential. A nontoxic in vivo single-dose evaluation for two binuclear mixed-valence Cu+1/Cu+2 redox-active coordination compounds, 72k and 61k, was conducted.
