Background: Over the past five years, the pregnancy rate in assisted reproductive technology (ART) programs in Russia has remained relatively stable. The aim of this study was to assess the distribution of monocyte and macrophage subsets in the blood and follicular fluid of infertile women undergoing assisted reproductive technology.
Methods: The study involved 45 women with a mean age of 35 ± 4.
Laser reduction of graphene oxide (GO) is a promising approach for achieving flexible, robust, and electrically conductive graphene/polymer composites. Resulting composite materials show significant technological potential for energy storage, sensing, and bioelectronics. However, in the case of insulating polymers, the properties of electrodes show severely limited performance.

However, the risk of minor stroke has been consistently higher with carotid artery stenting.
Objectives: The authors sought to evaluate the safety and effectiveness of a novel carotid stent system comprised of a stent, an adjustable integrated embolic filter and a postdilation balloon, in patients at elevated risk for adverse events from carotid endarterectomy.
Light environment in the Arctic differs widely with the seasons. Studies of relationships between objectively measured circadian phase and amplitude of light exposure and melatonin in community-dwelling Arctic residents are lacking. This investigation combines cross-sectional (n = 24-62) and longitudinal (n = 13-27) data from week-long actigraphy (with light sensor), 24-h salivary melatonin profiles, and proxies of metabolic health.

- PreHevbrio® is a 3-antigen hepatitis B virus (HBV) vaccine designed to produce three types of HBV envelope proteins, leading to a more robust immune response compared to traditional single-antigen vaccines.
- The study found that the increased immunogenicity of the 3-antigen vaccine is not linked to glycosylation, but rather to its ability to trigger T cell responses specific to the PreS antigens.
- Results show that the 3-antigen vaccine generates stronger and longer-lasting antibody responses, correlating significantly with T cell activity and better antibody production.
