The purpose of this study was to evaluate changes in brain activity during voluntary walking in normal subjects using technetium-99m-hexamethyl-propyleneamine oxime single photon emission computed tomography. This study included 14 normal subjects. Statistical parametric mapping analysis revealed that the supplementary motor area, medial primary(More)
The Wisconsin Card Sorting Test (WCST) is used clinically for evaluating frontal lobe function, but there is some controversy as to its specificity for detecting frontal lobe damage. To investigate the cerebral regions essential to the performance of the Card Sorting Test, we measured the regional cerebral blood flow (rCBF) in 18 normal subjects by PET(More)
Endometriosis, a common gynecological disorder that causes infertility and pelvic pain, is defined as the presence of endometrial glands and stroma within extra-uterine sites. However, despite extensive studies its etiology and pathogenesis are not completely understood. Differentially expressed genes were investigated in epithelial and stromal cells from(More)
OBJECTIVE To investigate differentially expressed genes in epithelial and stromal cells of eutopic endometrium from patients with deep endometriosis and women with normal pelvic cavities using laser capture microdissection and complementary DNA microarrays. DESIGN Prospective study. SETTING University hospital. PATIENT(S) Patients with deep(More)
We investigated apoptosis in tumor-infiltrating lymphocytes (TILs) obtained from 41 colorectal carcinomas by in situ nick translation (ISNT). When the ISNT labeling index (LI) was determined as the number of positive nuclei per 1000 nuclei of TIL in tissue sections, the median LI was 12.0 (range, 2-30). The ISNT LI of colorectal carcinoma with lymph node(More)
BACKGROUND Endometrium is derived from intermediate mesoderm via mesenchymal to epithelial transition (MET) during development of the urogenital system. By retaining some imprint of their mesenchymal origin, endometrial epithelial cells may be particularly prone to return to this state, via epithelial to mesenchymal transition (EMT). We hypothesized that(More)
The aberrant splicing isoform (PS2V), generated by exon 5 skipping of the Presenilin-2 (PS2) gene transcript, is a diagnostic feature of sporadic Alzheimer's disease (AD). We found PS2V is hypoxia-inducible in human neuroblastoma SK-N-SH cells. We purified a responsible trans-acting factor based on its binding to an exon 5 fragment. The factor was(More)
THE neural mechanisms of micturition in man were studied using single photon emission computed tomography (SPECT). The areas activated during micturition, relative to the resting state, were the upper pons, the left sensorimotor cortex, the right frontal cortex and the bilateral supplementary motor areas. Some of these regions have been established by(More)
OBJECTIVE To investigate mRNA expression of aromatase and 17beta-hydroxysteroid dehydrogenase type 2 (17betaHSD2) in epithelial and stromal cells from eutopic and ectopic endometrium of patients with deep endometriosis. DESIGN Prospective study. SETTING University hospital. PATIENT(S) Patients with deep endometriosis and fertile women with(More)
Expression levels of 8-hydroxydeoxyguanosine, a sensitive indicator of DNA damage resulting from oxidative stress, were significantly higher in samples of normal ovarian cortex surrounding endometriotic cysts when compared with ovarian cortex surrounding dermoid and serous ovarian cysts. These findings suggest that the normal ovarian cortex surrounding(More)
