A complex anthropological survey based on population-genetic methods and a study of a wide spectrum of genetic systems (43 alleles from 17 independent loci) was undertaken among 450 Buryat women of post-reproductive age. The results obtained showed the influence of particular genetic markers and their complex on the formation of peculiarities in the reproduction structure of the Buryat population.A sharp increase in phenotype GC 2-2 frequency and the corresponding GC*2 allele of the group-specific component (GC) was established for women groups with burdened obstetric records. These groups are characterized also by a considerable decrease in the observed geterozygosity (Ho) as compared to its expected value (He). Samples including women with multiple pregnancies in the recorded obstetric anamnesis are characterized by a significant increase in the frequency of the rare alleles TF*C3 of the transferrin system and those of PI*Z belonging to the proteinase inhibitor system (a1-antitrypsin) as compared to the control group. The results obtained widened current knowledge about the influence of genetic and environmental components on reproduction processes in human populations.

Multiple myeloma (MM) is a bone-marrow-based cancer of plasma cells. Over the last 2 decades, marked treatment advances have led to improvements in the overall survival (OS) of patients with this disease. Key developments include the use of chemotherapy, immunomodulatory drugs, proteasome inhibitors, and monoclonal antibodies.

The global prevalence of Parkinson's Disease (PD) is on the rise, driven by an ageing population and ongoing environmental conditions. To gain a better understanding of PD pathogenesis, it is essential to consider its relationship with the ageing process, as ageing stands out as the most significant risk factor for this neurodegenerative condition. PD risk factors encompass genetic predisposition, exposure to environmental toxins, and lifestyle influences, collectively increasing the chance of PD development.

Bacteriophages produce endolysins at the end of the lytic cycle, which are crucial for lysing the host cells and releasing virion progeny. This lytic feature allows endolysins to act as effective antimicrobial alternatives when applied exogenously. Staphylococcal endolysins typically possess a modular structure with one or two enzymatically active N-terminal domains (EADs) and a C-terminal cell wall binding domain (CBD).

Objectives: Childhood obesity is thought to influence pubertal development, according to observational studies. However, the exact causal relationship remains unclear due to the complexity of factors affecting pubertal development.
Methods: To explore the association between exposure (childhood obesity) and outcome (delayed puberty, height), we utilized various methods, including inverse-variance weighted (IVW), weighted median, weighted mode, and MR Egger regression.
