Novel Optical Criteria and Mechanisms of Critical Decline in Liver Regenerative Potential.

The most effective method of treating tumors localized in the liver remains resection. However, in the presence of concomitant pathology, the regenerative potential of the liver is significantly reduced. To date, there is insufficient fundamental data on the mechanisms responsible for the disruption of liver regeneration, and there is no effective method for assessing its regenerative potential.

[Therapeutic and diagnostic classification of degenerative spondylolisthesis: validation and multiple-center inter-observer agreement].

Object: To evaluate inter- and intra-observer agreement of the proposed diagnostic and treatment classification of degenerative spondylolisthesis.

Material And Methods: The proposed diagnostic and treatment classification of degenerative spondylolisthesis was validated according to the GRRAS protocol. For this purpose, we retrospectively analyzed MRI, CT and spinal radiography data in 20 patients.

Nanoparticles for Creating a Strategy to Stimulate Liver Regeneration.

Unlabelled: Presently, there is a need in the developing new approaches to stimulate liver regeneration, which would make its recovery more effective after resection. Application of nanoparticles, loaded with small bioactive molecules, with their targeted delivery into the liver is a promising approach. is to study the interaction of nanoparticles with various types of hepatic cells on the models of liver slices and primary hepatic cell cultures using the methods of multiphoton microscopy with fluorescence lifetime imaging.

Unexpected nanoscale CeO structural transformations induced by ecologically relevant phosphate species.

In the present study, the dissolution and microstructural transformation of CeO nanoparticles (NPs) in a phosphate-containing milieu were investigated. The dissolution behaviour of 2 nm and 5 nm CeO NPs in phosphate buffer solutions was found to differ markedly from that observed in 0.01 M NaClO.
