PURPOSE Detection of sentinel lymph node (SLN) metastasis in breast cancer patients has conventionally been determined by intraoperative histopathologic examination of frozen sections followed by definitive postoperative examination of permanent sections. The purpose of this study is to develop a more efficient method for intraoperative detection of lymph(More)
PURPOSE Adiponectin is a peptide hormone secreted from the adipose tissue, affecting the proliferation and insulin sensitivity of various types of cells. Because association of obesity with breast cancer risk is well established, it is possible that adiponectin plays some role in the development of breast cancer. Thus, in the present study, the association(More)
We developed a new endoscopic thyroid surgery by the axillo-bilateral-breast approach (ABBA) method, which is different from the previously described breast approach (BA) in that the port sites are modified to obtain a better view and to prevent the interference of surgical instruments. This modification also improves cosmetic results by eliminating the(More)
PURPOSE The association of BRCA2 polymorphisms at codon 372 [Asn (N)/His (H)]and codon 784 [Met (M)/Val (V)] with breast cancer risk was evaluated in Japanese women. In addition, the prognostic significance of these polymorphisms was studied in breast cancer patients. EXPERIMENTAL DESIGN A case-control study was conducted to examine the association of the(More)
PURPOSE Somatic mutations of PIK3CA, which encodes the p110alpha catalytic subunit of phosphatidylinositol 3-kinase, have recently been shown to play an important role in the pathogenesis and progression of human breast cancers. In this study, the frequency of PIK3CA mutations and their relationship with clinicopathologic and biological variables were(More)
In higher plants, O-phosphohomoserine (OPH) represents a branch point between the methionine (Met) and threonine (Thr) biosynthetic pathways. It is believed that the enzymes Thr synthase (TS) and cystathionine gamma-synthase (CGS) actively compete for the OPH substrate for Thr and Met biosynthesis, respectively. We have isolated a mutant of Arabidopsis,(More)
PURPOSE Recently, indocyanine green (ICG) has been used to visualize the internal limiting membrane during vitrectomy. After intraocular administration, ICG accumulates at the optic disc. In this study, the effects of ICG on retinal ganglion cells (RGCs) were examined. METHODS In vitro, rat RGCs were purified by a two-step immunopanning procedure, briefly(More)
A new apparatus has been developed using the laser speckle phenomenon for non-contact, two-dimensional analysis of tissue circulation in the choroid and optic nerve head (ONH). The fundus was illuminated by a diode laser spot and its image speckle was detected by an image sensor. The difference between the average of the speckle intensity (Imean) and the(More)
PURPOSE Breast cancer stem cells have been shown to be associated with resistance to chemotherapy in vitro, but their clinical significance remains to be clarified. The aim of this study was to investigate whether cancer stem cells were clinically significant for resistance to chemotherapy in human breast cancers. EXPERIMENTAL DESIGN Primary breast cancer(More)
Because there is no effective treatment for this retinal degeneration, potential application of cell-based therapy has attracted considerable attention. Several investigations support that bone marrow mesenchymal stem cells (MSCs) can be used for a broad spectrum of indications. Bone marrow MSCs exert their therapeutic effect in part by secreting trophic(More)
