If a regional lymph node taken during surgery for colorectal cancer is found to be free of tumour on histological examination this is taken to be a good sign. However, conventional staining may not be sensitive enough. Mutant-allele-specific amplification (MASA) is a technique that can detect, at the level of an individual cell, micrometastases to lymph(More)
Steroid hydroxylase cytochrome P450c17 has been previously purified from microsomal fractions of immature rat livers. In this study, we investigated the expression of P450c17 in rat livers to understand a role of steroidogenesis in the extrasteroidogenic tissue. Upon immunoblot analysis utilizing liver microsomes from rats, P450c17 was detected in 1 and 3(More)
The existence of cytochrome P450 2D isoforms in the brain has been demonstrated, although their physiological functions remain to be elucidated. In this study we demonstrated that recombinant rat cytochrome P450 2D1 and 2D4 and human cytochrome P450 2D6 possess progesterone 6 beta- and 16 alpha- hydroxylation activities; 2 beta- and 21-hydroxylation(More)
Basic fibroblast growth factor (bFGF) isolated from the brain and pituitary, has been shown to induce cell divisions in a variety of cell types. It also acts as a potent stimulator of angiogenesis, and it is important in the survival of several types of cultured neurons. Despite considerable information on the functions of bFGF, there is incomplete(More)
For identification of microsomal cytochrome P-450 (P-450) enzymes which catalyze 2- or 4-hydroxylations of estrogens in the rat liver, estradiol (E2) and estradiol 17-sulfate (E2-17-S) were selected as the substrates and incubated with various kinds of purified P-450 enzymes: PB-1, PB-2, PB-4 and PB-5 obtained from phenobarbital-treated male rats(More)
Discrepancies between previous light microscopic studies on the localization of basic fibroblast growth factor (bFGF) in neuroglias and neurons of the normal rat brain prompted us to investigate, by electron microscopy, the subcellular localization of bFGF-like immunoreactivity in neuroglias and neurons of the trigeminal motor and mesencephalic nuclei.(More)
A rare case of systemic multiple aneurysms located in the extracranial internal carotid artery, intracranial vertebral artery, and intraperitonial arteries is described. A 56-year-old woman was referred to our hospital with suspected rupture of an aneurysm of the right extracranial internal carotid artery. Digital subtraction angiography demonstrated a(More)
A PC-based interactive image processing system for 3-D analyses of stereo images of a scanning electron microscope (SEM) using an advanced feature-based stereo model is described. Integration between the global and qualitative human vision and the local and quantitative computer vision makes it possible to greatly reduce the computational load and to highly(More)
