Changes in the Transcription of Proliferation- and Apoptosis-Related Genes in Embryos in Women of Different Ages under the Influence of Extracellular Vesicles from Donor Follicular Fluid In Vitro.

We studied the influence of extracellular vesicles from the follicular fluid of a young donor on gene expression (MKI67, MYBL2, CCNB1, CCND1, CCNE1, CALM2, BAX, NDRG1, TP53I3, VEGF, VCAN, HAS2, CTSL2, PIBF1, RPL37, PFKP, GPX3, and AQP3) in embryos of women of different ages. According to nanoparticle tracking analysis data, the concentration of extracellular vesicles was 3.75±0.

Influence of Extracellular Vesicles from the Follicular Fluid of Young Women and Women of Advanced Maternal Age with Different miRNA Profiles on Sperm Functional Properties.

We studied the effect of co-culturing of extracellular vesicles in the follicular fluid of young women and women of advanced maternal age on sperm motility. Vesicles were obtained by differential centrifugation. The sperm fraction was isolated from the seminal fluid of 18 patients (age 28-36 years).

Influence of Extracellular Vesicles of the Follicular Fluid on Morphofunctional Characteristics of Human Sperm.

We studied the effect of extracellular vesicles of the follicular fluid on morphofunctional characteristics of human spermatozoa using CASA (computer-assisted sperm analysis) analytical system. The vesicles were obtained by sequential centrifugation at different rotational speeds and frozen at -80°C in the Sydney IVF Gamete Buffer medium. The sperm fraction was isolated from the seminal fluid of 21 patients aged 27-36 years by differential centrifugation in a density gradient.

Pathogenetic Therapy of Epidermolysis Bullosa: Current State and Prospects.

Epidermolysis bullosa is a severe hereditary disease caused by mutations in genes encoding cutaneous basement membrane proteins. These mutations lead to dermal-epidermal junction failure and, as a result, to disturbances in the morphological integrity of the skin. Clinically, it manifests in the formation of blisters on the skin or mucosa that in some cases can turn into non-healing chronic wounds, which not only impairs patient's quality of life, but also is a live-threatening condition.
