Liver is frequently injured in blunt abdominal trauma caused by road traffic accidents. The testing of safety performance of vehicles, e.g. belt usage, head support, seat shape, or air bag shape, material, pressure, and reaction, could lead to reduction of the injury seriousness. Current trends in safety testing include development of accurate computational human body models (HBM's) based on the anatomical, morphological, and mechanical behavior of tissues under high strain. The aim of this study was to describe the internal pressure changes within porcine liver, the severity of liver injury and the relation between the porcine liver microstructure and rupture propagation in an experimental impact test...

BACKGROUND AND AIMS: TRIM21 is a ubiquitin E3 ligase that is implicated in numerous biological processes including immune response, cell metabolism, redox homeostasis, and cancer development. We recently reported that TRIM21 can negatively regulate the p62-Keap1-Nrf2 antioxidant pathway by ubiquitylating p62 and prevents its oligomerization and protein sequestration function. As redox homeostasis plays a pivotal role in many cancers including liver cancer, we sought to determine the role of TRIM21 in hepatocarcinogenesis...

Acetaminophen (APAP) induced liver injury is the most common drug-induced liver injury, accounting for the top cause of acute liver failure in the United State, however the therapeutic options for it is very limited. Excess generation of reactive oxygen species (ROS) and the subsequent inflammatory responses are the major factors of the liver injury. Carbon monoxide (CO) is an important gaseous molecule with versatile functions including anti-oxidation and anti-inflammation, and we previous reported the therapeutic potential of a nano-designed CO donor SMA/CORM2 in a dextran sulphate sodium (DSS) induced mouse colitis model...

Rat genes, akr1c19 and RGD1564865, encode members (R1C19 and 20HSDL, respectively) of the aldo-keto reductase (AKR) 1C subfamily, whose functions, however, remain unknown. Here, we show that recombinant R1C19 and 20HSDL exhibit NAD+ -dependent dehydrogenase activity for prostaglandins (PGs) with 9α-hydroxy group (PGF2α , its 13,14-dihydro- and 15-keto derivatives, 9α,11β-PGF2 and PGD2 ). 20HSDL oxidized the PGs with much lower Km (0.3-14 μM) and higher kcat /Km values (0.064-2.6 min-1 μM-1 ) than those of R1C19...

The immunomodulatory effects of entecavir (ETV) in anti-hepatitis B virus (HBV) therapy have long been recognized. This study aimed to determine the effects of ETV on non-natural killer innate lymphoid cells (non-NK ILCs) in HBV-related liver disease progression. We enrolled treatment-naïve chronic hepatitis B (CHB) and HBV-related liver cirrhosis (LC) patients treated with ETV for 24 months. Before and after therapy, the frequency and cytokine profiles of ILC2s and non-NK ILCs subset homeostasis and their clinical significance were determined, and serial serum interferon (IFN)-λ levels were analyzed...

NK cells play a crucial role in the clearance of human viruses but their activity is significantly impaired in chronic hepatitis B infected patients (CHB). Cooperation with dendritic cells (DCs) is pivotal for obtaining optimal NK cell antiviral function, thus we investigated whether HBV might impact the ability of DCs to sustain NK cell functions. Human DCs were poor stimulators of IFN-γ production by NK cells when exposed to HBV, while maintained capability to trigger NK cell cytotoxicity. HBV prevented DC maturation but did not affect their expression of HLA class I, thus allowing DCs to evade NK cell lysis...
