[Rats' reproductive function under toxic load against the background of protein deficiency].

Safety assessment approaches of novel food, currently adopted in the Russian Federation, imply mandatory in vivo reproductive toxicity tests with the study of reproductive function and offspring development in order to obtain comprehensive evidence of the absence of distant adverse effects that may manifest only in the next generation. Comprehensive study of reproductive function, pre- and postnatal offspring development, as a rule, includes the research of a large number of parameters, all of which has a wide range of physiological fluctuations, and the heterogeneous distribution of some parameters' values complicates the interpretation of the results. of the study was to investigate the efficiency of a reduced adaptive potential model in rats, based on decreased diet protein intake, for the use in reproductive toxicity experiments.

Where in the tissues of Danio rerio is more H2O2 produced during acute hypoxia?

The lack of oxygen (O2) causes changes in the cell functioning. Modeling hypoxic conditions in vitro is challenging given that different cell types exhibit different sensitivities to tissue O2 levels. We present an effective in vivo platform for assessing various tissue and organ parameters in Danio rerio larvae under acute hypoxic conditions.

[Characteristics of Inferior Myocardial Infarction With a Special Electrocardiographic Pattern (Aslanger) in Metabolic Syndrome].

Aim: To evaluate the features of ST-segment elevation myocardial infarction with the Aslanger pattern in comparison with traditional forms of inferior myocardial infarction in metabolic syndrome.

Material And Methods: This study included 30 patients with inferior myocardial infarction in the presence of metabolic syndrome: 9 patients with the Aslanger electrocardiographic pattern (group 1, age 59.7 [58.

Redox differences between rat neonatal and adult cardiomyocytes under hypoxia.

It is generally accepted that oxidative stress plays a key role in the development of ischemia-reperfusion injury in ischemic heart disease. However, the mechanisms how reactive oxygen species trigger cellular damage are not fully understood. Our study investigates redox state and highly reactive substances within neonatal and adult cardiomyocytes under hypoxia conditions.
