Tyrosine phosphorylation of adaptor proteins permits the B cell antigen receptor (BCR)-associated protein tyrosine kinases to regulate downstream effector molecules. Here, we report the identification of a novel B cell adaptor for phosphoinositide 3-kinase (PI3K), termed BCAP. Tyrosine phosphorylation of BCAP is mediated by Syk and Btk, thereby providing(More)
Although less common than oesophageal varices in portal hypertension, gastric fundal varices carry a higher mortality rate when they rupture. They are less amenable to sclerotherapy. We have developed a minimally invasive balloon-occluded retrograde transverse obliteration (B-RTO) procedure to treat gastric fundal varices. B-RTO involves inserting a balloon(More)
In chronic obstructive pulmonary disease (COPD) which consists of emphysema and chronic bronchitis, alveolar tissue and/or bronchiolar walls are progressively destroyed. This suggests cell death by necrosis and/or apoptosis although no direct evidence of apoptosis has been reported. It was speculated that the apoptosis-related factors are associated with(More)
The testicular toxicities of two compound semiconductor materials, gallium arsenide (GaAs) and indium arsenide (InAs), and arsenic oxide (As2O3) were examined in rats by repetitive intratracheal instillation of these substances in suspension twice a week, a total of 16 times. A single instillation dose was 7.7 mg/kg in the GaAs and the InAs groups and 1.3(More)
We previously reported a truncated polyphemusin peptide analogue, T140, which efficiently inhibits infection of target cells by T-cell line-tropic strains of HIV-1 (X4-HIV-1) through its specific binding to a chemokine receptor, CXCR4. We have found that T140 is not stable in feline serum due to the cleavage of the C-terminal Arg,(14) indispensable for(More)
This study evaluates whether immunohistochemical staining using antibody TKH-2 is presented as a sensitive method for the histological diagnosis of amniotic fluid embolism (AFE). TKH-2 is the sensitive antibody clearly directed to sialyl Tn, NeuAc alpha 2-6GalNAc and reacts with meconium- and amniotic fluid-derived mucin-type glycoprotein. Formalin-fixed,(More)
BACKGROUND The optimal surgical resection method in patients with HCC to minimize the risk of local recurrence has not yet been determined. The aim of this study was to compare the prognosis following anatomical versus non-anatomical hepatic resection for hepatocellular carcinoma (HCC). METHODS Consecutive patients with HCC without macroscopic vascular(More)
Recombinant human transforming growth factor beta 1 (rhu TGF beta 1) was injected singly or repeatedly for 3-12 days into the periosteum of the right side parietal bone of neonatal rats under the period of bone growth, and the time course of histological changes of the bone was observed by light and electron microscopy and by enzyme histochemistry. The(More)
Betulinic acid, a triterpenoid isolated from the methyl alcohol extract of the leaves of Syzigium claviflorum, was found to have a potent inhibitory activity against human immunodeficiency virus type 1 (HIV-1). Betulinic acid derivatives were synthesized to enhance the anti-HIV activity. Among the derivatives, 3-O-(3',3'-dimethylsuccinyl) betulinic acid,(More)
Leukocyte cell-derived chemotoxin 2 (LECT2) is a recently isolated protein and has been shown to be synthesized by human hepatocytes. All hepatocytes show diffuse immunostaining for LECT2 within the cytoplasm. In the present study, an attempt was made to clarify the expression pattern of LECT2 in nine cases of low-grade malignant hepatocellular carcinoma(More)
