AIM:To evaluate the safety and efficacy of the bioartificial liver support system in canines with acute liver failure (ALF).METHODS:Nine canines with acute liver failure by acetaminophen-induced received TECA-I bioartificial liver support system (BALSS) from Hong Kong TECA LTD Co. Blood was perfused through a hollow fiber tube containing (1-2)X10(10) the porcine hepatocytes.In contrast, another 10 canines with acute liver failure by Acetaminophen received drugs. Each treatment lasted 6 hours.RESULTS:BALSS treatment resulted in beneficial effects for acetaminophen-induced ALF canines with survival and with the recovery of the liver functions and tissues, and plasma ammonia decreased from 135.9&mgr;mol/L plus minus 17.5&mgr;mol/L to 65.7&mgr;mol/L plus minus 22.0&mgr;mol/L, 32.5&mgr;mol/L plus minus 8.8&mgr;mol/L, GPT from 97.8U/L plus minus 8.7U/L to 64.8U/L plus minus 11.9U/L, 19.0U/L plus minus 6.3U/L, GOT from 103.0U/L plus minus 16.7U/L to 75.7U/L plus minus 19.6U/L, 26.5U/L plus minus 5.0U/L, and AKP from 158.3U/L plus minus 12.1U/L to 114.5U/L plus minus 19.8U/L, 43.8U/L plus minus 5.6U/L during and after the treatment. In contrast, 10 ALF canines in both the drug and control groups died 1 or 2 days after treatment.CONCLUSION: TECA-1 artificial liver support system is safe and efficacious for canines with acute liver failure.

: Clinical findings have shown a negative correlation between the severity of depressive symptoms and serum uric acid levels in men, yet the role of metabolic regulation in the pathophysiology of depression remains largely unknown. : In this study, we utilized an acute restraint-stress-induced male rat model of depression to investigate biochemical changes through NMR-based metabolomics combined with serum biochemical analysis. Additionally, we employed qPCR, immunoblotting, and enzyme activity assays to assess the expression and activity of xanthine oxidoreductase, the rate-limiting enzyme in uric acid production.

Hepatitis, a significant medical concern owing to its potential to cause acute and chronic liver disease, necessitates early intervention. In this study, we aimed to elucidate the histopathological features of lipopolysaccharide-induced hepatitis in mice, focusing on tissue alterations. The results demonstrated that hepatocytes exhibited decreased eosin staining, indicating cellular shrinkage, whereas sinusoids were swollen with blood cells.

Hepatitis A virus (HAV), a major cause of acute liver infections, is transmitted through the fecal-oral route and close contact with infected individuals. Current HAV standardized methods rely on the detection of virus antigen or RNA, which do not differentiate between infectious and non-infectious HAV. The objective of this study was to develop a prototype cell-based electrochemical biosensor for detection of infectious HAV.

Background And Objective: Iliopsoas abscess (IPA) is a rare condition with varied symptomology and etiology. Less than one-third of patients with IPA present in the emergency department (ED) with the traditional triad of fever, back pain, and restricted hip motion (or limp), leading to delays in diagnosis and management. Acute liver failure is also a rare clinical presentation in the ED, being associated with high morbidity and mortality.

Background/purpose: There have been no studies evaluating how body mass index (BMI) impacts on waitlist and post-liver transplant (LT) mortality in acute-on-chronic liver failure (ACLF) by sex. We aimed to determine these impacts using the United Network for Organ Sharing (UNOS) database.
Methods: Adults listed for LT with estimated ACLF (Est-ACLF) (2005-2023) were identified and subdivided by sex and BMI (high/middle/low).
