A retrospective comparative study of two groups of patients with decompensated liver disease, ascites and varices included in the LTWL, who received EBL (n = 41, group 1) and EBL + NSBB (n = 45, group 2).Results. The groups being compared did not differ in demographics, clinical parameters, MELD and Child-Turcotte-Pugh scores. There were no significant differences in the incidence of severe ascites, particularly diuretic-resistant ascites. The study groups did not differ in the incidence of medium-and large-sized varices. Incidence of bleeding did not differ in both groups. Overall mortality was significantly higher in the EBL + NSBB group than in the EBL group. Patient survival was lower, while mortality was higher in the EBL + NSBB group. The combined therapy group had a significantly higher number of acute kidney injury (AKI) than the EBL group.Conclusion. The compared methods are equivalently effective in preventing VB in patients with decompensated cirrhosis with a prolonged stay on the waiting list. Survival rate is significantly lower, while mortality is significantly higher in the EBL + NSBB group than in the EBL group.","PeriodicalId":21400,"journal":{"name":"Russian Journal of Transplantology and Artificial Organs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85228294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Male Wistar rats (n = 77) with an ELR model (70–75%) were divided into 3 groups: group 1 (control with a single intraperitoneal injection of saline), group 2 (single intraperitoneal injection of unsorted intact BMMCs at a dose of 30–35 × 106, and group 3 (single intraperitoneal injection of apoptotic BMMCs at the same dose). Restoration of biochemical parameters of liver function and mass, as well as the emerging microstructural changes in hepatocytes in histological preparations, were monitored by assessing hepatocyte mitotic activity (MA) during the first 7–10 days after ELR.Results. It was found that in groups 2 and 3, as compared with group 1, there was no death after ELR modeling, and that the biochemical parameters of liver function normalized more rapidly (at days 10–14). Hepatocyte MA in group 3 sharply increased as early as on day 1, and mitotic index (MI) averaged 14‰, reaching 20.9‰ in some experiments; MI in the control group remained at the baseline by this time, while in group 2, MI was only 3.2‰. In group 3, liver mass recovered more rapidly after ELR to baseline values already at days 8–10, whereas the recovery was at day 12–14 and day 17–20 in group 2 and group 1, respectively. It was suggested that the more pronounced increase in the efficiency of regenerative processes in the liver after ELR in group 3 after using apoptotic BMMCs was due to the release from these cells of a large spectrum of formed paracrine factors, including various classes of RNA molecules involved in the regeneration process.Conclusion. Apoptotic BMMNCs have a more effective adaptive and regulatory potential than intact BMMCs because reorganizations are rapidly formed in the damaged liver cells, providing an early and more powerful activation of the targeted regenerative program.","PeriodicalId":21400,"journal":{"name":"Russian Journal of Transplantology and Artificial Organs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87614771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiments were carried out on male Wistar rats (n = 80) aged 6–8 months with an initial weight of 230–250 g. CLD was modeled by inoculating the rats with 60% CCl4 oil solution for 42 days based on a modified scheme. Microgel based on recombinant spidroin rS1/9 was used as a matrix for CECs fabrication. Allogeneic liver cells (LCs) and multipotent bone marrow-derived mesenchymal stem cells (BM-MSCs) from a healthy donor were used as the cellular component of the CECs. The effectiveness of the corrective effect of the implanted CECs was assessed in an experimental CLD model (n = 60) in two groups of rats: Group 1 (control, n = 20, 1 mL of saline solution was injected into the damaged liver parenchyma) and Group 2 (experimental, n = 40, CECs containing allogenic LCs and BM-MSCs in a 5 : 1 ratio in a volume of 1 mL were implanted into the damaged liver parenchyma). For long-term monitoring of the CEC state, the CECs were labeled by additional inclusion in Cytodex-3. The effectiveness of the regulatory effect of CECs on regenerative processes in the liver was evaluated using biochemical, morphological and morphometric techniques, as well as by flow cytometry at 90 days after implantation.Results. In the control group, the mortality rate in CLD was 25%. There was no death in the experimental group with CLD after CEC implantation. The CECs were found to have a corrective effect on the biochemical and morphological parameters of the liver in CLD during 90 days of follow-up, with concomitant preservation of structural cellular homeostasis in the implanted CECs. Conclusion. Implantation of CECs in the liver facilitates effective correction of CLD by activating regenerative processes in the damaged liver, which is due to long-term preservation of structural cellular homeostasis in the CECs.","PeriodicalId":21400,"journal":{"name":"Russian Journal of Transplantology and Artificial Organs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85867939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the use of existing vascular patches is often associated with thrombosis, restenosis, calcification and other complications.Objective: to develop biodegradable patches for arterial reconstruction, containing vascular endothelial growth factor (VEGF) or arginyl-glycyl-aspartic acid (RGD), and comparatively evaluate their biocompatibility and efficacy in in vitro experiments and during preclinical trials in large laboratory animal models.Materials and methods. Biodegradable patches, made from a mixture of poly(3-hydroxybutyrate-co-3- hydroxyvalerate (PHBV) and poly(ε-caprolactone) (PCL), were fabricated by electrospinning and modified with VEGF or the peptide sequence RGD in different configurations. In in vitro experiments, the surface structure, physicomechanical and hemocompatibility properties were evaluated. In in vivo experiments, we evaluated the effectiveness of the developed vascular patches for 6 months after implantation into the carotid artery of 12 sheep. The quality of remodeling was assessed using histological and immunofluorescence studies of explanted specimens.Results. The PHBV/PCL/VEGF patches had physicomechanical characteristics closer to those of native vessels and their biofunctionalization method resulted in the smallest drop in strength characteristics compared with their unmodified PHBV/PCL counterparts. Modification with RGD peptides reduced the strength of the polymer patches by a factor of 2 without affecting their stress-strain behavior. Incorporation of VEGF into polymer fibers reduced platelet aggregation upon contact with the surface of the PHBV/PCL/VEGF patches and did not increase erythrocyte hemolysis. At month 6 of implantation into the carotid artery of sheep, the PHBV/PCL/ VEGF patches formed a complete newly formed vascular tissue without signs of associated inflammation and calcification. This indicates the high efficiency of the VEGF incorporated into the patch. In contrast, the patches modified with different configurations of RGD peptides combined the presence of neointimal hyperplasia and chronic granulomatous inflammation present in the patch wall and developed during bioresorption of the polymer scaffold.Conclusion. PHBV/PCL/VEGF patches have better biocompatibility and are more suitable for vascular wall reconstruction than PHBV/PCL/RGD patches.","PeriodicalId":21400,"journal":{"name":"Russian Journal of Transplantology and Artificial Organs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90723609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For decellularization, microdispersed cartilage particles (MCPs), obtained by cryomilling, were incubated in detergent solutions (sodium dodecyl sulfate and Triton X-100), then treated with supercritical carbon dioxide (scCO2) with 10% ethanol and DNase I. The Ames test (Salmonella typhimurium reverse mutation assay) was used to determine the genotoxicity of decellularized microdispersed cartilage particles (dMCPs). Local and general toxic effects, as well as resorption of dMCPs were studied in vivo on sexually mature outbred rats. Decellularized MCP specimens (10 mg) were implanted into the thigh muscle tissue. Viability of human adipose-derived mesenchymal stem/stromal cells (hAdMSCs), when cultured on dMCPs, was analyzed by in vivo microscopy, stained with fluorescent Calcein AM dye. Cell metabolic activity was assessed using PrestoBlue™ Cell Viability Reagent.Results. It has been proven that porcine dMCPs implanted in rat muscle after treatment with scCO2 do not exhibit local and general toxic effects, and do not show genotoxicity and negative effects on the reproductive system of animals. After 6 months of in vivo experiment, most (87%) of the implanted decellularized cartilage was resorbed. It was shown that the resulting matrices are able to support adhesion and proliferation of hAdMSCs. Conclusion. Porcine dMCP specimens are suitable for biocompatible medical products in terms of local and general toxic effects, genotoxicity and reproductive toxicity, and can be used as a matrix for creating cell- and tissue-engineered cartilage constructs.","PeriodicalId":21400,"journal":{"name":"Russian Journal of Transplantology and Artificial Organs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91067527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
