Recent Progress in Photocatalytic Applications of Electrospun Nanofibers: A Review.

Electrospun fiber-based photocatalysts demonstrate significant potential in addressing global environmental and energy challenges, primarily due to their high specific surface areas and unique properties. This review examines recent advances in the application of these materials in photocatalytic processes, with a particular focus on water splitting and hydrogen production. The principles of the electrospun method are described in detail, along with the operating parameters, material characteristics, and environmental conditions that affect the fiber formation.

[Reconstruction of caval veins].

Objective: To study the possibilities and results of reconstruction of caval veins.

Material And Methods: We analyzed the results of reconstruction of caval veins in 31 patients (19 men and 12 women) including superior vena cava (SVC) in 5 cases and inferior vena cava (IVC) in 26 cases. Penetrating wounds with vascular damage were found in 8 patients.

[Some aspects of iatrogenic vessel injury].

Iatrogenic events made up 1-10% of in-hospital mortality. Currently, iatrogenic vascular injuries are described for almost all surgical areas. Incidence of iatrogenic vascular injuries is gradually increased that is primarily associated with high number of percutaneous endovascular interventions.

[Non-standard method of reconstruction of the abdominal aorta for a giant aneurysm].

Abdominal aortic aneurysms are encountered predominantly in elderly patients suffering from severe concomitant diseases. Therefore, the rate of various complications associated with resection of aortic aneurysm amounts to 30%, with lethality in separate cohorts of patients reaching 43.7%.

[THE STATE AND PERSPECTIVES OF DEVELOPMENT OF TRAUMATOLOGICAL ORTHOPEDIC OUT-PATIENT CARE TO POPULATION OF THE PRIVOLJSKII FEDERAL OKRUG].

The article presents the results of analysis ofmanpower support of specialized out-patient traumatological orthopedic care in the Privoljskii federal okrug. The manpower deficiency of traumatologist-orthopedist at the out-patient stage was established especially especially in rural area. This is cause of low indicators ofdispensary monitoring of patients with consequences of traumas and diseases of musculo-skeletal system and factual unavailability of rehabilitation care to patients of given profile.
