[Optical coherence tomography angiography in the differential diagnosis of iris melanoma and progressive iris nevus].

Unlabelled: Considering the similarity in clinical presentations of iris neoplasms of various origins, questions of their noninvasive diagnosis remain relevant. Optical coherence tomography angiography (OCT-A) is one of the imaging method that enables visualization of tumor vessels.

Purpose: This article examines the features of angioarchitecture, vascular network density, and perfusion density of iris melanoma and progressive iris nevus using OCT-A.

[Intravenous thrombolytic therapy of ischemic stroke with the drug Revelisa in real clinical practice: results of the IVT-AIS-R study].

Objective: Evaluation of the safety and effectiveness of thrombolytic therapy (TLT) with the drug Revelisa (alteplase) in patients with ischemic stroke (AI) in real clinical practice.

Material And Methods: An open prospective multicenter non-interventional register study was conducted, which included 550 patients with AI - 259 (47.1%) women and 291 (52.

[Use of optical coherence tomography angiography in assessment in conjunctival vascular architecture in health and pathology].

Purpose: Investigation of the capabilities of anterior segment (AS) optical coherence tomography angiography (OCTA) in evaluation of conjunctival vascular architecture in healthy individuals and in various pathological conditions.

Material And Methods: The study included 17 healthy volunteers (34 eyes; the control group) and 62 patients (68 eyes) with conjunctival lesions of various nature. All participants underwent AS-OCT and AS-OCTA with assessment of qualitative (vessels pattern, lumen, pathologic tortuosity) and quantitative parameters (vessel density (VD, %) in the lesion area).

Size-Dependent Structural, Magnetic and Magnetothermal Properties of YFeO Fine Particles Obtained by SCS.

Iron-containing oxides are the most important functional substance class and find a tremendous variety of applications. An attractive modern application is their use in biomedical technologies as components in systems for imaging, drug delivery, magnetically mediated hyperthermia, etc. In this paper, we report the results of the experimental investigation of submicron YFeO garnet particles obtained in different sizes by solution combustion synthesis (SCS) using glycine organic fuel to discuss the interdependence of peculiarities of the crystal and magnetic structure and size's influence on its functional magnetothermal performance.

Association of gene polymorphisms with body weight changes in prediabetic patients.

Background: Recent research has demonstrated that Type 2 Diabetes (T2D) risk is influenced by a number of common polymorphisms, including MC4R rs17782313, PPARG rs1801282, and TCF7L2 rs7903146. Knowledge of the association between these single nucleotide polymorphisms (SNPs) and body weight changes in different forms of prediabetes treatment is still limited. The aim of this study was to investigate the association of polymorphisms within the MC4R, PPARG, and TCF7L2 genes on the risk of carbohydrate metabolism disorders and body composition changes in overweight or obese patients with early carbohydrate metabolism disorders.
