Numerical Investigations of the Effect of Nonlinear Quadratic Pressure Gradient Term on a Moving Boundary Problem of Radial Flow in Low-Permeable Reservoirs with Threshold Pressure Gradient

open access: yes, 2015
The existence of a TPG can generate a relatively high pressure gradient in the process of fluid flow in porous media in low-permeable reservoirs, and neglecting the QPGTs in the governing equations, by assuming a small pressure gradient for such a ...

Exposure–Recovery Approach for Hepatic Toxicity Analysis of Pyrethroid Lambda‐Cyhalothrin: Histopathological, Histochemical, and Biochemical Responses in Oreochromis niloticus

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Lambda‐cyhalothrin is a synthetic pyrethroid insecticide widely used in agriculture, but its potential to contaminate aquatic ecosystems and exert high toxicity on fish at low concentrations raises ecotoxicological concerns. While standard histopathological and biochemical assessments are common, the novel integration of pigment‐based ...

Effect of Visualized Respiratory Training on Patient Cooperation and Image Quality in Gadoxetic Acid Disodium‐Enhanced Liver MRI: A Randomized Controlled Trial

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Respiratory motion artifacts impair diagnostic accuracy in gadoxetic acid disodium (Gd‐EOB‐DTPA)‐enhanced liver MRI. Conventional verbal pre‐scan breathing training often yields inconsistent patient cooperation and image quality, creating an urgent clinical need for optimized training methods.

Pharmacokinetics and Pharmacodynamics of a Single Oral Dose of Ascelia‐Manganese‐Based MRI Contrast Agent (ACE‐MBCA) in Adult Subjects With and Without Hepatic Impairment

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Orally administered Ascelia‐manganese‐based contrast agent (ACE‐MBCA) is used for liver MRI, but its feasibility in patients with hepatic dysfunction remains unknown. Purpose To investigate the pharmacokinetics (PK), pharmacodynamics, and safety of ACE‐MBCA in subjects without/with hepatic impairment.

[Portal pressure should be measured on suspicion of portal hypertension]

open access: yes, 2010
Portal hypertension leads to serious complications such as oesophageal varices, ascites, and in some patients hepatocellular carcinoma (HCC). The importance of measurement of the hepatic venous pressure gradient (HVPG) has recently been substantiated as ...

Portal hypertension contributes to ascites formation via the Piezo1−nuclear factor kappa-B−aquaporin1 pathway in liver cirrhosis

open access: yesExperimental and Molecular Medicine
Portal hypertension is critical to the development of ascites in liver cirrhosis. The aim of our study was to evaluate the contribution of portal hypertension to ascites formation and explore the underlying mechanism.
