In this investigation, we report identification and characterization of a 95 kDa postsynaptic density protein (PSD-95)/discs-large/ZO-1 (PDZ) domain-containing protein termed tamalin, also recently named GRP1-associated scaffold protein (GRASP), that interacts with group 1 metabotropic glutamate receptors (mGluRs). The yeast two-hybrid system and in vitro(More)
Layer 1 in the developing cerebral cortex is populated by two basic neuronal cell types, Cajal-Retzius (CR) cells and non-CR cells. We generated transgenic mice in which green fluorescent protein (GFP) was driven by the promoter of metabotropic glutamate receptor subtype 2 and expressed specifically in CR cells during cortical development. On the basis of(More)
Glutathione S-transferases (GSTs), superoxide dismutase 2 (SOD2) and NAD(P)H:quinone oxidoreductase 1 (NQO1) are anti-oxidant enzyme genes. Polymorphisms of GSTs, SOD2 and NQO1 have been reported to influence individual susceptibility to various diseases. In an earlier study, we obtained preliminary findings that a subset of glutathione S-transferase T1(More)
The access to sufficient numbers of spermatogonial stem cells (SSCs) is a prerequisite for the study of their regulation and further biomanipulation. A specialized medium and several growth factors were tested to study the in vitro behavior of bovine type A spermatogonia, a cell population that includes the SSCs and can be specifically stained for the(More)
PURPOSE Nocturia has a major impact on quality of life and affects numerous aspects of health. Lifestyle modifications are expected to be helpful in improving nocturia. However, the efficacy of this strategy has not been established. We tested the efficacy of nondrug lifestyle measures as a first step in treating nocturia and found factors predictive of the(More)
PURPOSE Septins are the major constituents of the annulus, a submembranous ring that separates the middle and principal pieces of spermatozoa. We previously reported its essential role in spermiogenesis and reproduction in mice. In the current study we investigated septin abnormality in infertile men. MATERIALS AND METHODS Semen samples from 108 infertile(More)
Spermatogonial stem cells (SSC) are a small self-renewing subpopulation of type A spermatogonia, which for the rest are composed of differentiating cells with a very similar morphology. We studied the development of primary co-cultures of prepubertal bovine Sertoli cells and A spermatogonia and the effect of glial cell line-derived neurotropic factor (GDNF)(More)
A 58-year-old man presented with lasting nasal obstruction. He had undergone right nephrectomy for renal cell carcinoma 11 years ago and right lobectomy for pulmonary metastasis 10 years ago. Paranasal sinus CT scans showed a soft tissue mass in the bilateral maxillary sinus. Abdominal CT showed left renal mass. Each mass was enhanced on the(More)
Although nocturia has been reported to increase mortality in elderly individuals, the particular risk factors that are associated with this event are unclear. Therefore, we evaluated risk factors for death in outpatients with nocturia. Between October 2002 and December 2009, 250 consecutive patients with nocturia were enrolled in two general hospitals in(More)
