[Main mechanisms of secondary ischemic brain damage formation in case of craniocerebral injury].

Objective: To systematize the mechanisms of formation and morphology of secondary ischemic brain damage, formed in the case of craniocerebral injury.

Material And Methods: A literature review devoted to the study of formation mechanisms of secondary ischemic brain damage in craniocerebral injury was conducted. The secondary sequential and secondary long-term ischemic brain damage in the posttraumatic period, as well as intracranial and extracranial factors that contribute to their occurrence and progression, were considered.

Vascular-targeted micelles as a specific MRI contrast agent for molecular imaging of fibrin clots and cancer cells.

Molecular medical imaging is intended to increase the accuracy of diagnosis, particularly in cardiovascular and cancer-related diseases, where early detection could significantly increase the treatment success rate. In this study, we present mixed micelles formed from four building blocks as a magnetic resonance imaging targeted contrast agent for the detection of atheroma and cancer cells. The building blocks are a gadolinium-loaded DOTA ring responsible for contrast enhancement, a fibrin-specific CREKA pentapeptide responsible for targeting, a fluorescent dye and DSPE-PEG.

Pharmacokinetics and biodistribution study of self-assembled Gd-micelles demonstrating blood-pool contrast enhancement for MRI.

Magnetic resonance angiography (MRA) requires the use of contrast agents (CAs) to enable accurate diagnosis. There are currently no CAs on the market with appropriate pharmacokinetic (PK) parameters, namely long persistence in the blood, that can be easily used for MRA. We have recently synthesized amphiphilic building blocks loaded with gadolinium (Gd), which self-assemble into Gd-micelles in aqueous media, and have evaluated their potential as a blood-pool contrast agent (BPCA) in vivo.

[The diagnostic screening of acute leukemia using new technologies of automated blood analysis.].

The leukemia is a neoplastic clonal disease of hematopoietic system with primary affection of bone marrow. The modern technologies of automated blood analysis permit to implement a quick primary screening of pathological samples of blood suspicious for presence of blast cells. The application of various analysis techniques (optical, cytochemical, immune phenotypical) with the purpose of detecting blast cells demonstrates their different distribution at the graphics.

MRI micelles self-assembled from synthetic gadolinium-based nano building blocks.

A synthetic nano building block endowed with amphiphilic properties and chelated gadolinium is presented. Spontaneous self-assembly into small 12 nm corona-core stealth Gd-micelles with inherently high gadolinium loading occurs in water. Gd-Micelles are a new blood pool contrast agent with high relaxivity for magnetic resonance imaging.
