A rapid approach to monitor ablative therapy through optimizing shape and elasticity parameters is introduced. Our motivating clinical application is targeting and intraoperative monitoring of hepatic tumor thermal ablation, but the method translates to the generic problem of encapsulated stiff masses (solid organs, tumors, ablated lesions, etc.) in ultrasound imaging. The approach involves the...
The results of treatment 367 patients operated on in the proctology department Samarkand State Medical University, clinic No 1 during 2015-2022 are reviewed article, among which with necrotic forms disease amounted to 26 (7.1%) patients. Among them 341 (92.9%) had aerobic etiology peritoneal tissue lesions. average age was 62.1±3.9 years.
Magnetic Resonance Imaging has the ability to describe vessel wall thickness, plaque structure, distinguish fibrotic, fatty, calcific or hemorrhagic contents with excellent soft tissue contrast. Our aim in this study is determine symptomatic and asymptomatic carotid morphology imaging properties. We tried understand whether components images match histopathological sections. MRI was performed 3...
BACKGROUND Previous studies suggest that erythrocyte membranes from intraplaque hemorrhage into the necrotic core are a source of free cholesterol and may become a driving force in the progression of atherosclerosis. We have shown that MRI can accurately identify carotid intraplaque hemorrhage and precisely measure plaque volume. We tested the hypothesis that hemorrhage into carotid atheroma st...
PURPOSE To develop a Gamma Knife-based mouse model of late time-to-onset, cerebral radiation necrosis (RN) with serial evaluation by magnetic resonance imaging (MRI) and histology. METHODS AND MATERIALS Mice were irradiated with the Leksell Gamma Knife® (GK) PerfexionTM (Elekta AB; Stockholm, Sweden) with total single-hemispheric radiation doses (TRD) of 45- to 60-Gy, delivered in one to thre...
Disposition characteristics of model macromolecules with different physicochemical characteristics and macromolecular prodrugs of mitomycin C, namely mitomycin C-dextran conjugates, were studied in tissue-isolated tumor preparations of Walker 256 carcinoma with the use of a single-pass vascular perfusion technique. In constant infusion experiments, all radiolabeled macromolecules accumulated in...

Abstract Raman Spectroscopy is able to provide a fast identification method for healthy and pathological tissues without the need sample preparation. This makes it highly interesting intraoperative use in identifying tumor types borders. However, capability of machine-learning classifier recognize known based on spectra relies solid ground truth that usually provided by measuring small tissue s...
clostridial myositis, considered to be rare in pet animals, is an acutely fatal toxaemic condition. some species of clostridia are responsible for necrotic myositis. a 2-year-old male german shepherd dog was admitted with non-weight bearing lameness and massive swelling of the left hind limb. clostridium perfringens type a with alpha toxin was diagnosed as a pathogenic agent. based on the histo...
