Activin A, an important member of transforming growth factor-β superfamily, is reported to inhibit proliferation of mature hepatocyte. However, the effect of activin A on growth of hepatic progenitor cells is not fully understood. To that end, we attempted to evaluate the potential role of activin A in the regulation of hepatic progenitor cell(More)
Hepatic stem cell niche plays an important role in hepatic oval cell-mediated liver regeneration. As a component of hepatic stem cell niche, the role of hepatic stellate cells (HSCs) in oval cell proliferation needs further studies. In the present study, we isolated HSCs from rats at indicated time point after partial hepatectomy (PH) in(More)
OBJECTIVE To propose a criterion and its significance of clinical classification of hepatic hydatidosis complicated with biliary fistula. METHODS 47 hepatic hydatidosis with biliary fistula cases who were given a subadventitial pericystectomy were observed from 2000 to 2005 in a retrospective study. The methods included observation of the different(More)
This paper studied the fatty acid composition, reactive oxygen species (ROS), lipoxygenase (LOX) activity, and malondialdehyde (MDA) content in the leaves and roots of Malus hupehensis seedlings under effects of cadmium (Cd) stress. Noticeable changes were observed in the kinds and relative contents of fatty acids after treated with CdCl2 for 7-12 hours.(More)
OBJECTIVE To investigate the expression and distribution of osteopontin (OPN) in Echinococcus multilocularis cyst, and explore the role of OPN in the metastasis of hepatic E. multilocularis infection. METHODS Forty gerbils were infected with 20% E. multilocularis suspension (0.1 ml per gerbil) through abdominal opening injection in liver. Gerbils were(More)
Liver tissues around hydatid from 8 patients with cystic echinococcosis were observed by transmission electron microscopy, normal hepatic tissues of 6 cases were used as control. The results demonstrated predominant atrophy and necrosis of hepatocytes. These changes seem to be the major hepatic lesion in cystic echinococcosis.
The feature extraction of protein sequences is a challenging problem. It might need a lot of theoretical and practical knowledge from many fields. The difficulty would increase when investigators extract the features solely from protein sequences. In this paper, we present a method of protein granularity. The concepts of protein granularity, granularity(More)
Gastric cancer is the fourth most common type of cancer and the second cause of cancer‑related mortalities worldwide despite the use of multimodal therapy. Cadherins are transmembrane glycoproteins that are involved in tumorigenesis. CDH17 has been found to be over‑expressed in gastric cancer and its overexpression was associated with lymph node metastasis(More)
BACKGROUND To investigate the safety and feasibility of a new intrahepatic cholangiojejunostomy for multiple intrahepatic biliary ductal openings after hepatobiliary resection. MATERIALS AND METHODS Forty-eight pigs were randomly assigned into two groups: the new intrahepatic cholangiojejunostomy group (n = 24); and the control group (n = 24) with(More)
Currently, there are many ways to generate new formal contexts from the original ones. Among these ways, combining formal contexts is the simplest one. This paper mainly discusses the attribute characteristics in the composition of two formal contexts, which is called the combined formal context. It is proved that there exists a strong connection between(More)
