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.

[Present-day possibilities of surgical management of tumour-like forms of arteriovenous angiodysplasias].

Described herein is the treatment policy pursued in a relatively uncommonly encountered variant of congenital vascular pathology, i. e. arteriovenous angiodysplasias.

[Combined methods of treatment the congenital arterio-venous fistulas of peripheral vessels].

A 10-year experience and results of combined methods of surgical treatment of arterio-venous fistulas of peripheral vessels in 50 patients were analyzed. The patients were systematized on the basis of existing classifications, clinical manifestations of the disease, methods of invasive (ultrasound dopplerography and duplex scanning) and invasive (angiography) examinations. According to many authors no one of conventional methods of surgical treatment of arterio-venous fistulas which are used singly can be effective and must not be recommended as the most optimal.

[The combined strategy in treatment of lymphangiodysplasia].

The experience of treatment of a rare form of pathology of the lymphatic system was analyzed. The surgical tactics, depending on both the dimentions and the form of lymphangiodysplasia, were described. The absence of the pain sensitivity and large tumor size were the main reason of medical help seeking for the patients on the late stages of the disease.

Revascularization in distal lesions of upper extremity arteries.

A study was made of the course of ischemia and hemodynamic disorders in 53 patients with occlusion of the distal arterial system of the upper extremities. Circulation was examined by ultrasound Doppler, tetrapolar rheology, transcutaneous oxymetry and angiography. Critical ischemia was discovered in 58.

Traumatic injuries of the popliteal and tibial arteries: limb ischemia and problems of surgical management.

This paper analyzes the results of examination of 106 patients with traumatic injuries of the popliteal (n=36) and leg arteries (n=70) including gunshot (n=48), punctured and incized (n=32), contused-crushed (n=17) wounds and blunt (n=9) traumas. Sixty-two patients were admitted within 8 hours of injury and 20 within 8 to 24 hours, 24 patients within 1 to 15 days. Sixty-five patients had been rendered first aid at other medical institutions.

[Surgical strategy in traumatic lesions of the popliteal artery].

An examination and treatment of 32 patients with injured popliteal arteries are analyzed. Among the etiological factors there were gunshot wounds (16), crushed (4), punctured-incised (7) and blunt (7) traumas. Combined injuries of the popliteal vein were diagnosed in 12 patients, and injuries of the bones--in 16 patients.

Surgical management of traumatic injuries to the tibial arteries.

Altogether 60 patients with traumatic injuries to the tibial arteries were entered into the study. Twenty-four patients presented with gunshot, 24 with stab and incised, 10 with contused and lacerated wounds, and 2 patients had blunt traumas. Thirty-nine patients were admitted to the clinic within the period as long as 8 hours since the time of wounding, 9 patients within 8 to 24 hours, and 12 patients within the period as long as one to 15 days.
