Development, Pre-Clinical Safety, and Immune Profile of RENOVAC-A Dimer RBD-Based Anti-Coronavirus Subunit Vaccine.

The development of effective and safe vaccines and their timely delivery to the public play a crucial role in preventing and managing infectious diseases. Many vaccines have been produced and distributed globally to prevent COVID-19 infection. However, establishing effective vaccine development platforms and evaluating their safety and immunogenicity remains critical to increasing health security, especially in developing countries.

Predictive model for orbital target volume for reconstruction in hyperostotic sphenoid wing meningiomas.

Objective: To devise a predictive model for estimating the requisite volume of the orbit in patients poised for resection of hyperostotic spheno-orbital meningiomas.

Material And Methods: The predictive regression model was conceived through the retrospective analysis of perioperative radiological data from 25 patients who initially underwent surgery at the Burdenko Neurosurgery Center for hyperostotic spheno-orbital meningiomas grade I. The model quality metrics were evaluated utilizing the performance library in the R programming language, including the Akaike Information Criterion, Bayesian Information Criterion, adjusted R-squared, Root Mean Squared Error, and Sigma.

[The dynamics of provision of population of the Russian Federation with otorhinolaryngologists in 2018-2023].

The most acute problem of state health care system is shortage of medical personnel, both physicians and paramedics. The purpose of the study is to assess dynamics of personnel support with otolaryngologists in medical organizations of the Russian Federation for 2018-2023. The retrospective analytical descriptive study was carried out using continuous method based on studying dynamics of personnel support with otolaryngologists in the Russian Federation in general, Federal Okrugs and particular Subjects of the Russian Federation for 2018-2023.

Superhydrophobic Electrospun PI/PTFE Membranes with Ultralow Dielectric Constants for High-Frequency Telecommunication.

High-frequency, high-power, and high-speed telecommunication in a complex environment promotes the development of dielectric materials toward a low dielectric constant, low dielectric loss, good thermal properties, and long-term reliability. Here, polyimide/polytetrafluoroethylene (PI/PTFE) nanofiber membranes with an inherent super hydrophobicity, excellent dielectric properties, good thermal stability, and enhanced tensile strength were prepared via a simple electrospinning strategy and an imidization reaction. The obtained PI/PTFE membranes demonstrate a superlow average dielectric constant of 1.
