Introduction: The massive hepatic necrosis of acute liver failure (ALF) results in a sudden loss of hepatic cells. Although most hepatocyte cells of ALF are completely lost, stem cell-derived circulating cells and endogenous progenitor cells rapidly regenerate them. Mesenchymal stem cells (MSCs) have a critical role in the regeneration of liver injury through regulating platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF) levels. However, their fluctuating levels in the healing process and correlation to the decrease of liver function markers remain unclear. The aim of this study was to analyze the effects of MSCs in accelerating liver regeneration of ALF by measuring VEGF and PDGF levels on day 2 and 7, as well as SGPT and SGOT levels, and assessing histopathology appearance. Methods: Using an ALF rat model, 12 animals were randomly assigned into two groups: umbilical cord (UC)-MSC injection (T1) and vehicle control (Veh). ELISA assay was employed to measure PDGF and VEGF levels, an automatic analyzer was used to assess serum glutamic pyruvic transaminase (SGPT) and serum glutamic oxaloacetic transaminase (SGOT), and hematoxylin and eosin (H&E) staining was used to evaluate morphological appearance. Results: The study showed an significant (P<0.001) increase of PDGF and VEGF levels on the 2nd day, followed by a decrease on the 7th day, along with a decrease of SGPT and SGOT levels as well as the normality of histology appearance. Conclusion: In conclusion, administration of MSCs may accelerate liver regeneration of ALF through PDGF and VEGF regulation.

BACKGROUND: Osteoarthritis (OA) is generally considered a degenerative joint disease caused by biomechanical changes and the ageing process. In OA pathogenesis, the development of OA is thought to be regulated largely by excess matrix metalloproteinase (MMP), which contributes to the degradation of extracellular matrices such as MMP-1 and Interleukin-4. AIM: This study aims to prove the influence of Mesenchymal Stem Cell Wharton Jelly on decreasing MMP-1 levels and increasing IL-4 which is a specific target as a target component in cases of osteoarthritis in vivo. MATERIAL AND METHODS: This research is an experimental study with the design of Post-Test-Only Control Group Design. The sample consisted of 16 OA rats as a control group and 16 OA rats treated with MSC-WJ as a treatment group. OA induction is done by injection of monosodium iodoacetate (MIA) into the intra-articular right knee. Giving MSC-WJ is done in the third week after MIA induction. The serum MMP-1 and IL-4 levels were measured after 3 weeks treated with MSC-WJ using the ELISA method. The statistical test used is an independent t-test. The value of p < 0.05 was said to be statistically significant. RESULTS: The result showed that serum MMP-1 levels were higher in the group treated with MSC-WJ than in the control group (p < 0.05). Serum IL-4 levels were higher in the group treated with MSC-WJ than in the control group (p < 0.05). CONCLUSION: This study concluded that MSC-WJ increased MMP-1 levels and IL-4 levels in serum OA rats. MSC-WJ showed a negative effect on MMP-1 in the serum of OA rats.

Pre-S2 start codon mutation was higher in Indonesian patients compared to other Asian countries, and its prevalence was associated with advanced liver disease, particularly in HBeAg⁺ patients.

BACKGROUND: Osteoarthritis (OA) is one of the most common diseases among the elderly. OA occurs due to an imbalance between degradation and synthesis in articular joint tissue, causing changes in joint components such as cells, matrices and molecular production. Therefore, knowledge of cartilage-degrading enzymes such as ADAMTS-4 and iNOS is needed. AIM: This study aims to prove the effect of Mesenchymal Stem Cell Wharton Jelly on decreasing ADAMTS-4 levels as cartilage-degrading enzymes and increasing levels of iNOS which showed the immunosuppressive potential of MSC-WJ in cases of osteoarthritis in vivo. MATERIAL AND METHODS: This research is an experimental study with the design of Post-test-Only Control Group Design. The sample consisted of 16 OA rats as a control group and 16 OA rats treated with MSC-WJ as a treatment group. OA induction is done by injection of monosodium iodoacetate (MIA) into the intra-articular right knee. Giving MSC-WJ is done in the third week after MIA induction. The serum ADAMTS-4 and iNOS levels were measured after 3 weeks treated with MSC-WJ using the ELISA method. The statistical test used is an independent t-test. The value of p < 0.05 was said to be statistically significant. RESULT: The result showed that serum ADAMTS-4 levels were lower in the group treated with MSC-WJ than in the control group, but not statistically significant (p > 0.05). Serum iNOS levels were higher in the group treated with MSC-WJ than in the control group (p < 0.05). CONCLUSION: This study concluded that MSC-WJ significantly reduced ADAMTS-4 levels and increased the serum iNOS levels of OA rats.

Background: Plectranthus amboinicus (Lour.) Spreng is a plant that has a high flavonoid content. The leaves of Plectranthus amboinicus (Lour.) Spreng contain many flavonoids Chrysoeriol, Cirsimaritin, Eriodictyol, Luteolin, Rutin, Salvigenin, Thymoquinone, Quercetin, Apigenin, and 5-O-Methyl-Luteolin. Objectives: To determine the antioxidant activity and anticancer activity of flavonoid compounds contained in Plectranthus amboinicus (Lour.) Spreng. Methods: Anticancer activity testing was carried out by in silico against several cancer receptors and antioxidant activity testing was carried out by in vitro using the 1,1-Diphenyl-2-Picryhydrazil method. The results showed that the flavonoid compounds contained in Plectranthus amboinicus (Lour.) Spreng have similar anticancer activity to the reference molecule at the P-Glycoprotein-1, Cyclin Dependent Kinase-2, and Phosphoinositide-3-Kinase receptors, as well as better anticancer activity than the reference molecule for the Cyclooxygenase-2 and Phosphoenolpyruvate Carboxykinase receptors. Results: The antioxidant activity of the extract gave an Inhibitory Concentration 50% value of 9.77 µg/mL, the flavonoid compounds contained in Plectranthus amboinicus (Lour.) Spreng gave an Inhibitory Concentration 50% value that lower than the extract, which ranged from 6.92 µg/mL to 8.50 µg/mL. Flavonoids in Plectranthus amboinicus (Lour.) Spreng anticancer activity by in silico molecular docking and antioxidant activity by in vitro 1,1-Diphenyl-2-Picryhydrazil method. Conclusions: All the flavonoid compounds contained in the ethanolic extract of Plectranthus amboinicus (Lour.) Spreng leaves exhibit very strong anti-cancer and antioxidant activity, which results in ethanolic extract of Plectranthus amboinicus (Lour.) Spreng leaves have very strong antioxidant activity.
