Abstract

The use of nanostructured components in drug manufacturing and, more specifically, targeted drug delivery has recently become a major trend in the pharmaceutical industry. Nanodrugs encompass a wide range of pharmaceutical agents containing dendrimers, nanocrystals, micelles, liposomes, and polymer nanoparticles. Liposomes are the most well-studied nanoparticles and effective drug carriers. However, the more complex their structure is, the more process controls are needed and the more quality attributes have to be monitored, including the chemical properties of the liposomal fraction such as the shape, size and charge of the nanoparticle, conjugation efficacy, and distribution of the active ingredient. We believe that quality control of key liposome characteristics should rely on dynamic and laser light scattering coupled with electrophoresis, differential scanning calorimetry, cryo-electron microscopy, nuclear magnetic resonance, laser diffraction analysis, and gel filtration chromatography.

Highlights

  • Carotid artery stenosis is a risk factor for ischemic stroke

  • The inclusion criteria were: any gender; an active chronic ischemic cerebrovascular disease; internal carotid artery (ICA) surgery performed from May 2015 to December 2018 at the Department of Vascular and Endovascular Surgery (27 patients underwent carotid endarterectomy (CEE), 63 patients underwent carotid angioplasty with stenting)

  • The development of cognitive impairment (CI) was associated with the severity of brachiocephalic arteries (BCA) atherosclerosis, advanced age, arterial hypertension, coronary heart disease, diabetes mellitus, previous cerebral circulation failures

Summary

Introduction

Surgical treatment is often used to improve cerebral perfusion and prevent the development of cerebrovascular pathology and related cognitive impairment. The aim of this prospective pilot study was to evaluate the cognitive functions (CF) of patients after surgery (open or endovascular intervention) on the internal carotid artery. Compliance with ethical standards: the study was approved by the Research Center of Neurology Ethics Committee (protocol No 11/14 of November 19, 2014) All patients or their legally authorized representatives have signed the informed consent for surgery; the study followed the ethical principles of the Declaration of Helsinki (1975). Через 3 и 6 месяцев после операции у пациентов наблюдали небольшие разнонаправленные изменения КФ (по шкале MMSE), но к концу срока наблюдения (9 месяцам) распределение оценок КФ у пациентов приблизилось к дооперационному (р = 0,43). Для оценки связи КФ с множественными интраоперационными эмболиями сосудов мозга требуется более длительное наблюдение
