Quantitative Parameters of Lysozyme in Organs and Tissues of Female Pikes Esox lucius (Esocidae) during Gonad MaturationBiology Bulletin Reviews - Tập 13 - Trang 674-680 - 2023
M. F. Subbotkin, T. A. Subbotkina
The effect of the development of female pike Esox lucius gonads on the quantitative parameters of lysozyme, a component of nonspecific resistance, and the size of some organs of the immune system was studied from September to April. It was established that there is a significant decrease in the concentration of lysozyme in the serum and spleen during the period of female maturation and gonad devel...... hiện toàn bộ
Biological effects of Wolbachia pipientis: Elucidation of genetic mechanismsBiology Bulletin Reviews - Tập 5 - Trang 109-118 - 2015
I. I. Goryacheva, B. V. Andrianov
The intracellular alpha-proteobacteria Wolbachia pipientis infects about 40% of arthropod species from all major taxonomic groups; it also infects nematodes. Such a wide range of host species is unusual for highly specialized parasites, which include Wolbachia; it may be associated with the adaptation to the presence of germplasm in cells that exhibit minimal evolutionary variability in animals.

The Renewing Species. A Common Population-Genetic Explanation of Species Phenomena for Sexual and Asexual OrganismsBiology Bulletin Reviews - Tập 9 - Trang 385-392 - 2019
A. Pshenichnov
I suggest a common population genetic mechanism that explains persistence of biological species as consistently reproducing groups of similar organisms: genetic renewal due to genetic drift or selection, which restricts genetic diversity of populations. In contrast to concepts explaining species integrity via interbreeding, the concept of drift- and selection-induced genetic renewal explains speci...... hiện toàn bộ
Nucleotide substitutions in rDNA of evolutionarily static angiosperm groupsBiology Bulletin Reviews - Tập 1 - Trang 110-124 - 2011
V. S. Chupov, E. M. Machs
In this study we examine nucleotide substitutions in rDNA ITS1 of a number of evolutionarily static angiosperm taxa. It has been demonstrated that, in the majority of cases, cytosine-to-thymine substitutions in CpG dinucleotides prevail. The rate of cytosine-to-thymine substitutions in other neighboring positions is on the average twice as small. The rate of all other substitution types is 4–10 ti...... hiện toàn bộ
Interspecies hybridization in the origin of plant species: Cases in the genus Poa sensu latoBiology Bulletin Reviews - Tập 5 - Trang 366-382 - 2015
N. N. Nosov, E. O. Punina, E. M. Machs, A. V. Rodionov
A comparative analysis of the ITS sequences and several chloroplast genome sequences of the Poa and their relative species showed that the genus Poa contained a significant amount of species originating from intersectional, and in some cases intergeneric, hybridization (between species Poa and species of subtribe Puccinellinae). The position of several new Poa hybrids founded in the Altai Mountain...... hiện toàn bộ
Molecular Markers of Caspase-Dependent and Mitochondrial Apoptosis: Role in the Development of Pathology and Cellular SenescenceBiology Bulletin Reviews - Tập 8 - Trang 472-481 - 2018
A. S. Diatlova, A. V. Dudkov, N. S. Linkova, V. Kh. Khavinson
The data on the molecular mechanisms of normal and pathological apoptosis are summarized. Three phases of apoptosis are distinguished: signal, effector, and degradation. The signal phase includes the extrinsic (caspase-dependent) and extrinsic (mitochondrial) pathways. Molecular markers of extrinsic and extrinsic apoptotic pathways play an important role in the diagnostics and treatment of immune,...... hiện toàn bộ
