Bowel Colonization With Carbapenem-Resistant Bacteria Is Associated With Short-Term Outcomes in Patients With Acute-On-Chronic Liver Failure.

Background: Bowel colonization with antimicrobial-resistant bacteria has been associated with worse clinical outcomes in patients with cirrhosis; however, it has not been studied in patients with acute-on-chronic liver failure (ACLF). We evaluated whether fecal isolation of carbapenem-resistant gram-negative bacteria (CR-GNB) among patients with ACLF affects short-term outcomes.

Methods: Patients of APASL-ACLF (n = 339) were screened between June 2020 and December 2021, and 150 were included.

Decoding Hydrogen Desorption Kinetics in Porous Silicon: An Electrical Circuit Modeling Approach.

Solid-state hydrogen storage outperforms conventional storage methods in terms of safety and on-board applications. Porous Si (PS) is the optimized Si nanostructure with ample surface area (∼400 m g) and maximum dangling sites for hydrogenation. Though solid-state hydrogen storage in Si nanostructures, especially in porous Si, is extensively studied, the thermal desorption of hydrogen is rarely reported.

Intrabiliary pressure in the pathophysiology of extra hepatic biliary obstruction.

Background And Aim: The aim of this study was to evaluate the role of intrabiliary pressure (IBP) in the pathophysiology of extrahepatic biliary obstruction (EHBO) during percutaneous transhepatic biliary drainage (PTBD).

Materials And Methods: Adult patients with EHBO who underwent PTBD were prospectively enrolled. IBP was recorded during primary PTBD.

Palmitic acid causes hepatocyte inflammation by suppressing the BMAL1-NAD-SIRT2 axis.

Palmitic acid is the most abundant saturated fatty acid in circulation and causes hepatocyte toxicity and inflammation. As saturated fatty acid can also disrupt the circadian rhythm, the present work evaluated the connection between clock genes and NAD+ dependent Sirtuins in protecting hepatocytes from lipid-induced damage. Hepatocytes (immortal cells PH5CH8, hepatoma cells HepG2) treated with higher doses of palmitic acid (400-600μM) showed typical features of steatosis accompanied with growth inhibition and increased level of inflammatory markers (IL-6 IL-8, IL-1α and IL-1β) together with decline in NAD+ levels.
