Advances and perspectives in animal models of human hepatitis A virus

Animal Models and Experimental Medicine, EarlyView.
Following HAV infection, humans, non‐human primates, and Ifnar1−/− mice develop characteristic manifestations of hepatitis A, including fecal viral shedding, elevated serum ALT levels, and inflammatory cell infiltration in the liver. In contrast, HAV‐infected human liver chimeric mice exhibit fecal viral shedding but do not develop clinical features of

Image hashing framework for tampering localization in distorted images

IEICE Electronics Express, 2010
Many image hashing algorithms have been proposed to detect the malicious tampering for content authentication. However, their tampering localization performance degrades dramatically on images with content-preserving distortion, as these algorithms cannot distinguish the malicious tampering from content-preserving distortion.

Animal models in molecular biology research: Challenges, ethical imperatives, and the path to human‐relevant translation

Animal Models and Experimental Medicine, EarlyView.
The graphical abstract shows how molecular biology research has shifted from using traditional animal models toward using methods that are more relevant to humans. It points out the main problems, differences between species, difficulty in reproducing results, moral issues, and lack of infrastructure that make translational accuracy harder to achieve ...

IL‐31 levels correlate with pruritus in patients with cholestatic and metabolic liver diseases and is farnesoid X receptor responsive in NASH

Hepatology, EarlyView., 2022
IL‐31 levels correlate with pruritus in patients with cholestatic and metabolic liver diseases Abstract Background and Aims Pruritus is associated with multiple liver diseases, particularly those with cholestasis, but the mechanism remains incompletely understood.

A SECURE IMAGE AUTHENTICATION ALGORITHM WITH PIXEL-LEVEL TAMPER LOCALIZATION *

, 2008
In this paper, we use a generalized model for all the previously proposed pixel-wise authentication schemes. Then we show how this model can be compromised with an oracle attack.
