BACKGROUND Oxidative stress and inflammation are implicated in the process of liver regeneration. Lactulose orally administered can be bacterially fermented and induces dramatic amounts of endogenous hydrogen. Hydrogen has been confirmed to have antioxidant and anti-inflammatory properties. This study investigated the potential influence of lactulose(More)
In recent years there is a growing interest in the study of sparse representation for signals. This article extends this research into a novel model for object classification tasks. In this model, we first apply the non-negative K-SVD algorithm to learning the discriminative dictionaries using very few training samples and then represent a test image as a(More)
In order to improve the convergent speed of the particle swarm optimization (PSO) algorithm in the control of real-time polarization mode dispersion (PMD) compensation, we apply a new gradient method to PSO algorithm in this paper. We call this new algorithm GTPSO. To compare the convergent speed of PSO and GTPSO algorithm, a test is carried out by(More)
Hypoxia/reoxygenation (H/R) injury of cholangiocytes causes serious biliary complications during hepatobiliary surgeries. Molecular hydrogen (H2) has been shown to be effective in protecting various cells and organs against oxidative stress injury. Human liver cholangiocytes were used to determine the potential protective effects of hydrogen against(More)
Hip Osteoarthritis (OA) is a common disease among the middle-aged and elderly people. Conventionally, hip OA is diagnosed by manually assessing X-ray images. This study took the hip joint as the object of observation and explored the diagnostic value of deep learning in hip osteoarthritis. A deep convolutional neural network (CNN) was trained and tested on(More)
