[Possibilities of a software-based hybrid single photon emission computed tomography/magnetic resonance imaging in the diagnosis of complicated diabetic foot syndrome].

Objective: To give the results of a software-based hybrid single photon emission computed tomography/magnetic resonance imaging (SPECT/MRI) in detecting osteomyelitis (OM) in patients with diabetic foot syndrome (DFS).

Material And Methods: Seventy-six patients (35 men and 41 women) (mean age, 59.4 +/- 7.

[Different types of 199Tl chloride scintigraphic visualization of malignant tumors of the locomotor apparatus].

Background: 201Tl chloride scintigraphy allows malignant tumors of the locomotor apparatus to be diagnosed. The capacities of scintigraphy with 199Tl chloride, a 201Tl chloride analog, in addition to routine visualization of malignant tumors of the locomotor apparatus, have revealed its untypical variants.

Objective: to study the specific features of 199Tl chloride scintigraphic visualization of malignant tumor processes in the locomotor apparatus.

Mitochondria-targeted plastoquinone derivatives as tools to interrupt execution of the aging program. 4. Age-related eye disease. SkQ1 returns vision to blind animals.

Mitochondria-targeted cationic plastoquinone derivative SkQ1 (10-(6'-plastoquinonyl) decyltriphenylphosphonium) has been investigated as a potential tool for treating a number of ROS-related ocular diseases. In OXYS rats suffering from a ROS-induced progeria, very small amounts of SkQ1 (50 nmol/kg per day) added to food were found to prevent development of age-induced cataract and retinopathies of the eye, lipid peroxidation and protein carbonylation in skeletal muscles, as well as a decrease in bone mineralization. Instillation of drops of 250 nM SkQ1 reversed cataract and retinopathies in 3-12-month-old (but not in 24-month-old) OXYS rats.

New method of in vitro culturing of pigment retinal epithelium in the structure of the posterior eye sector of adult rat.

We propose a new method of organotypic roller 3D-culturing of the posterior sector of the eye. The method allows maintaining tissue viability in vitro for 14 days (which considerably surpasses the capacities of stationary culturing) and studying of the behavior, of pigment retinal epithelial cells and choriocapillary membrane. Using this method we demonstrated phenotypic transformation, migration, and proliferation of pigment retinal epithelial cells under conditions of roller organotypic culture.
