Background And Aim: The success of partial donor liver transplantation is affected by the implantation site of the donor liver and the vascular reconstruction approach. We investigated the effects of different donor liver implantation sites and vascular reconstruction approaches on liver regeneration using a rat kidney-sparing heterotopic auxiliary liver transplantation model, with portal vein arterialization (PVA).
Methods: Sixty male Sprague-Dawley rats underwent end-to-end anastomosis of the donor liver portal vein and the right renal artery stent (control group), or end-to-side anastomosis of the donor liver portal vein and the left common iliac artery (experimental group).
Results: The experimental group had significantly lower plasma levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, and cholinesterase than the control group (all, P < 0.05). The levels of tumor necrosis factor-α (TNF-α), interleukin 6 (IL-6), and hepatocyte growth factor (HGF) in the liver were significantly higher in the experimental group than that in the control group (all, P < 0.05). Hematoxylin and eosin (HE) staining of the liver tissue specimens indicated that the experimental group had greater hepatocyte regeneration compared to the control group.
Conclusions: The modified kidney-sparing PVA model of heterotopic auxiliary liver transplantation is more conducive to liver regeneration with quicker return of liver function.

UW supplementation with AP39 improves liver viability following static cold storage.

Static cold storage of donor livers at 4 °C incompletely arrests metabolism, ultimately leading to decreases in ATP levels, oxidative stress, cell death, and organ failure. Hydrogen Sulfide (HS) is an endogenously produced gas, previously demonstrated to reduce oxidative stress, reduce ATP depletion, and protect from ischemia and reperfusion injury. HS is difficult to administer due to its rapid release curve, resulting in cellular death at high concentrations.

Background: The viability of the liver pre-transplant depends on the type of donor, age, medical history, circumstances of death, result of analytics, and complementary exploration of the abdominal cavity. Abdominal ultrasound is the initial option for the assessment of previously unknown liver disease, such as the qualitative determination of hepatic steatosis . The presence of hepatic steatosis is considered a risk factor for graft failure after liver transplantation, therefore, at the time of clinical assessment of the donor or its presence in the macroscopic assessment in the operating room can be cause for rejection of the organ by the transplant teams.

Background: The spectrum of metabolic dysfunction-associated steatotic liver disease (MASLD) is highly prevalent, affecting 30% of the world's population, with a significant risk of hepatic and cardiometabolic complications. Different stages of MASLD are accompanied by distinct gut microbial profiles, and several microbial components have been implicated in MASLD pathophysiology. Indeed, earlier studies demonstrated that hepatic necroinflammation was reduced in individuals with MASLD after allogenic faecal microbiota transplantation (FMT) from healthy donors on a vegan diet.

End-stage liver disease includes liver failure and decompensated cirrhosis resulting from various etiologies and often leads to patient mortality due to complications and clinical symptoms such as severe jaundice, ascites, hepatic encephalopathy, coagulopathy, and hepatorenal syndrome. Liver transplantation is currently regarded as the most effective treatment, but its clinical application is limited by the shortage of donors, elevated expenses, and post-transplant rejection. Stem cells are a group of cells with multidirectional differentiation potential and self-renewal ability, which can improve the clinical indicator outcomes through mechanisms such as immunoregulation and promotion of tissue repair in patients with end-stage liver disease.

Living donor liver transplantation (LDLT) has been, and continues to be, an excellent solution for many patients worldwide. Although the procedure poses significant risks for the liver donor due to its complexity, the challenge of obtaining cadaveric donors in time to prevent mortality on the waiting list makes this type of liver transplantation (LT) very common in many countries.
