Functional UV Blocking and Superhydrophobic Coatings Based on Functionalized CeO and AlO Nanoparticles in a Polyurethane Nanocomposite.

Water repellency has significant potential in applications like self-cleaning coatings, anti-staining textiles, and electronics. This study introduces a novel nanocomposite system incorporating functionalized AlO and CeO nanoparticles within a polyurethane matrix to achieve hydrophobic and UV-blocking properties. The nanoparticles were functionalized using an octadecyl phosphonic acid solution and characterized by FTIR and XPS, confirming non-covalent functionalization.

[Moscow scientific schools on the field of internal medicine in the second half of the XIX - early XX centuries: comparative characteristics].

Peculiarities and comparative characteristics of three main Moscow schools on the field of internal medicine of the second half of the XIX - early XX centuries are discussed: schools of Grigory Zakharyin, Alexey Ostroumov and Vassily Shervinsky - Leonid Golubinin; the legitimacy to acknowledge scientific clinical schools of Mikhail Cherinov and Nikolay Golubov is disputed. The arguments are provided that of the Moscow therapeutic schools, it was the Shervinsky-Golubinin school, and not the Zakharyin or Ostroumov school, that played the most significant role in the formation of the internal medicine in the USSR, in passing the accumulated knowledge and ideas to therapeutic elites in the USSR.

Drug Policy in the Russian Federation.

Objectives: To describe characteristics of the drug policy in Russia in terms of health technology assessment (HTA), registries of patients, pricing of drugs, cost-containment methods, and reimbursement of drugs.

Methods: The legal and regulatory frameworks and the literature were reviewed to analyze several aspects of Russian healthcare: the scheme of cooperation between its structures, its levels, drug provision, issues related to HTA, the reimbursement system, pricing of medicines, and cost-containment methods.

Results: The Russian drug policy has improved over the last few years: HTA has been developed, rules for the pricing of drugs and cost-containment methods have been established, and registries of patients have been created.
