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)
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)
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)
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)
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)
PURPOSE Recently, Ki67 index (cell proliferation marker) has been attracting a considerable attention as a prognostic factor in breast cancer but the prognostic significance of Ki67 after neoadjuvant chemotherapy (NAC) has rarely been examined. EXPERIMENTAL DESIGN Primary breast cancer patients (n = 102) treated with NAC (sequential paclitaxel 12 cycles(More)
Glutathione S-transferase P1 (GSTP1) belongs to a family of phase II metabolic enzymes that can detoxify the carcinogens and cytotoxic drugs by conjugating them with glutathione. Relationship of GSTP1 CpG islands hypermethylation or GSTP1 protein expression with clinicopathological characteristics of breast cancers was studied. The CpG islands(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)
