BACKGROUND The hypofunction of the N-methyl-D-aspartate (NMDA) subtype of glutamate receptors has been implicated in the pathophysiology of schizophrenia. Several lines of evidence suggest that D-serine may function as an endogenous agonist of the glycine site of the NMDA receptor. The aim of this study was to examine whether serum levels of D- and L-serine(More)
Several lines of evidence suggest that D-serine may function as an endogenous agonist of the glycine site on the N-methyl-D-aspartate (NMDA) receptor that has been implicated in the pathophysiology of Alzheimer's disease (AD). The purpose of the study was to determine whether serum levels of D- and L-serine in patients with AD are altered as compared with(More)
A recent report demonstrated that serum levels of epidermal growth factor (EGF) were significantly decreased in patients with schizophrenia, suggesting that impaired EGF signaling might be associated with the pathophysiology of schizophrenia. Our goal in the present study was to determine whether serum levels of EGF are altered in patients with(More)
BACKGROUND To examine a subclass-effect relationship and a dose-effect relationship of autoantibodies in the rat antiglomerular basement membrane (GBM) antibody-induced glomerulonephritis (anti-GBM nephritis) model, we injected homologous monoclonal antibodies against the NC1 domains of rat type IV collagen into inbred Wistar-Kyoto (WKY) rats. METHODS(More)
Midkine (MK) is a heparin binding growth factor and promotes growth, survival and migration of various cells including neurons. It is also known to accumulate in senile plaques of patients with Alzheimer's disease (AD). To investigate the involvement of serum MK in the pathophysiology of AD, serum MK levels were determined in patients with AD (n=36) and(More)
BACKGROUND Although the outcomes of pancreatic cancer have been improved by gemcitabine, the changes in its characteristics and long-term outcomes within the gemcitabine era remain unclear. This study was conducted to identify clinical characteristics of pancreatic cancer patients within the gemcitabine era. METHODS A retrospective chart review was(More)
Basic fibroblast growth factor (bFGF) is a multifunctional growth factor that has been implicated in a variety of neurodevelopmental processes. The aim of the present study was to examine whether bFGF contributes to the pathophysiology of schizophrenia. Serum bFGF levels in 40 patients with schizophrenia (15 drug-naive and 25 medicated patients) and in 40(More)
PURPOSE We investigated pharmacological properties, functional alterations and gene expression of the muscarinic receptor system in young and old Goto-Kakizaki rat bladders. MATERIALS AND METHODS Male 12 and 70-week-old Goto-Kakizaki rats and age matched male Wistar rats were used in this study. Bladder function was estimated by voiding behavior,(More)
BACKGROUND Nephrogenic diabetes insipidus (NDI) is a rare disease whose complications include polyuria, renal dysfunction, growth disorder and mental retardation. The details of NDI's clinical course have been unclear. To address this uncertainty, we performed a large investigation of the clinical course of NDI in Japan. METHODS Between December 2009 and(More)
We report a 14-year-old boy with Castleman disease in this article. He complained of short stature, and his body height was 133.8 cm (<3rd percentile; z score -4.5). There was marked delay in the appearance of secondary sexual characteristics. He was found to have a remittent fever and a lower mid-abdominal tumor. Blood test revealed microcytic hypochromic(More)
