We analyzed DNA from 63 Japanese men with either azoospermia or severe oligospermia whose Y chromosomes were cytogenetically normal. A total of 16 loci were examined: 15 loci on the long arm between DYS7E and DYZ1, and the YRRM1 locus, a candidate gene for the azoospermic factor, AZF. One patient with a pericentric inversion of the Y chromosome was also(More)
PURPOSE Prostate cancer epidemiology has been marked overall by a downward risk migration over time. However, in some populations, both in the United States and abroad, many men are still diagnosed with high-risk and/or advanced disease. Primary androgen deprivation therapy (PADT) is frequently offered to these patients, and disease risk prediction is not(More)
The possible involvement of immunoglobulin G4 (IgG4) in the pathogenesis of idiopathic sclerosing lesions has been suggested. In this study, a clinicopathologic analysis was performed to reveal characteristics of retroperitoneal fibrosis relating to IgG4. The study involved 17 patients with retroperitoneal fibrosis. Immunohistochemistry revealed numerous(More)
PURPOSE We performed a randomised controlled study regarding the effects of androgen replacement therapy (ART) on lower urinary tract symptoms (LUTS) in hypogonadal men with benign prostate hypertrophy (BPH). METHODS Fifty-two patients with hypogonadism and BPH were randomly assigned to receive testosterone (ART group) as 250 mg of testosterone enanthate(More)
Membrane-type 1 matrix metalloproteinase (MT1-MMP) is expressed both in carcinoma cells and in surrounding stromal fibroblasts. MT1-MMP localizes to the surface of tumor cells and is thought to play an important role in tumor invasion. To analyze the mechanism of MT1-MMP gene expression in epithelial tumor cells, the dog kidney epithelial cell line(More)
We analyzed DNA from 153 Japanese men with azoospermia or severe oligozoospermia whose Y chromosomes were cytogenetically normal. A total of 23 loci on the Y chromosome were examined: 15 loci within interval 6 including YRRM1 and DAZ, and 8 loci outside interval 6. Microdeletions were observed in 20 individuals. All deletions involved at least one locus(More)
The influence of muscarinic receptor stimulation and blockade on the central regulation of micturition was evaluated in conscious female rats. Saline was infused into the bladder to induce repeated bladder contractions and voiding. Increasing doses of a muscarinic agonist, oxotremorine-M (OXO-M; 0.01 to 1 microg/rat) or antagonist, atropine (0.1 to 30(More)
BACKGROUND Based on the data of current status of endocrine therapy for prostate cancer registered in the Japan Study Group of Prostate Cancer (J-CaP), we conducted an analysis of primary androgen deprivation therapy (PADT) and an interim analysis of the prognosis. METHODS Of the 26 272 cases registered in the server of J-CaP, the 19 409 cases initially(More)
One of the most critical issues in prostate cancer clinic is emerging hormone-refractory prostate cancers (HRPCs) and their management. Prostate cancer is usually androgen dependent and responds well to androgen ablation therapy. However, at a certain stage, they eventually acquire androgen-independent and more aggressive phenotype and show poor response to(More)
