Increasing evidence on the adverse health impacts of microplastics (MPs) is available, but their associated risks to the well-being of humans and long-term impacts are poorly understood. An indicator of the remote effects of MPs may be their influence on the rate of aging. To assess the effects of MPs on the aging process, we used accelerated senescence OXYS rats that develop a complex of geriatric diseases.

- A(H5Nx) avian influenza viruses are widespread and evolving, with a notable emergence of highly pathogenic A(H5N1) clade 2.3.4.4b reassortant viruses since 2020.
- Some of these viruses, particularly those isolated from mammals, carry a mutation (E627K) in the PB2 protein that enables adaptation to mammalian cells.
- Recent findings from Russia reveal a highly pathogenic A(H5N1) virus with the E627K mutation that shows increased virulence in mice and limited airborne transmission in ferrets, underscoring the need for ongoing surveillance to mitigate pandemic risks.
Background: It is believed that alterations in the functioning of the cytochrome P450 (CYP), which participates in metabolic transformations of endogenous polyunsaturated fatty acids (PUFAs) (with the formation of cardioprotective or cardiotoxic products), affects the development of age-related cardiovascular diseases and reduces the effectiveness of some cardioselective drugs. For example, CYP2J2 activation or CYP1B1 inhibition protects against the cardiovascular toxicity of anticancer drugs. It is currently unclear whether CYPs capable of metabolizing arachidonic acid and ω-3 PUFAs to vasodilatory and vasoconstrictive derivatives are expressed in all heart regions.

Consolidation of data on the role of ω-3 PUFAs in child development may increase the professional's awareness, help to plan clinical studies, and develop recommendations for supplementation. of the research was to analyze literature data on the effect of ω-3 PUFAs on the central nervous system, immune system, and vision in children.
