BACKGROUND Biliary atresia (BA) is a neonatal cholestatic disease of unknown etiology. It is the leading cause of liver transplantation in children. Many similarities exist between BA and graft versus host disease suggesting engraftment of maternal cells during gestation could result in immune responses that lead to BA. The aim of this study was to determine the presence and extent of maternal ...

breast cancer is the second largest cause of cancer deaths among women. at the same time, it is also among the most curable cancer types if it can be diagnosed early. this paper presents a novel hybrid intelligent method for recognition of breast cancer tumors. the proposed method includes three main modules: the feature extraction module, the classifier module and the optimization module. in t...

BACKGROUND AND PURPOSE Subclinical atherosclerotic plaques are common in patients with pontine infarctions (PIs) but without basilar artery (BA) stenosis. We hypothesized that BA plaque locations may differ by PI type and vertical location as well as vertebrobasilar artery geometry. METHODS Ninety-six patients with PI but without BA stenosis on magnetic resonance imaging (MRI) and magnetic re...

By immunizing mice with killed whole bacterial cells of Brucella abortus S (99), a panel of six hybridomas producing monoclonal antibodies (mAb) specific for the surface antigens of this bacterium were produced. ELISA was used to screen the hybridoma supernatants. Immunoblots of the cell extract indicated that three mAb were specific for S-LPS (Ba-1, Ba-2, Ba-3) and three others were reactive w...

Two oligopeptides containing phosphinothricin were accumulated in the culture of bialaphos (BA) producer Streptomyces hygroscopicus SF1293 when large amount of BA was added to the culture at idio phase. One of the oligopeptides was a new substance, BA dimer (phosphinothricyl-alanyl-alanyl-phosphinothricyl-alanyl-alan ine), and the other was a known substance called If (phosphinothricyl-alanyl-a...

The metabolism of the carcinogen benz[a]anthracene (BA), a tetracyclic aromatic hydrocarbon, by Cunninghamella elegans was investigated. C. elegans grown on Sabouraud dextrose broth transformed [14C]BA to labeled BA trans-8,9-dihydrodiol (90%), BA trans-10,11-dihydrodiol (6%), and BA trans-3,4-dihydrodiol (4%), but not to BA trans-5,6-dihydrodiol. These metabolites were separated by thin-layer ...

Serum bile acids (BA) reference values are lacking for neonates. Therefore, this study aimed to determine serum BA reference values in term and preterm neonates. Furthermore, as serum BA concentrations are well-known to rise in septic adults, BA values were determined in early-onset neonatal sepsis (EOS), a common and serious disease in neonates.Using high-performance liquid chromatography-high...

AIM To compare responses to therapy of Black African (BA) and non-Black African (non- BA) patients with hepatitis C virus genotype 4 (HCV-4) residing in Belgium. METHODS In this retrospective multicenter study, 473 patients with HCV-4 were selected from databases at 7 Belgian centers; 209 treatment-naive patients (154 BA) had received treatment with peg-interferon (peg-IFN) plus ribavirin (RB...

Bile acids (BAs) are recently recognized signalling molecules that profoundly affect metabolism. Because of detergent-like toxicity, BA levels must be tightly regulated. An orphan nuclear receptor, Small Heterodimer Partner (SHP), plays a key role in this regulation, but how SHP senses the BA signal for feedback transcriptional responses is not clearly understood. We show an unexpected function...
