The growth cone is responsible for axonal growth, where membrane expansion is most likely to occur. Several recent reports have suggested that presynaptic proteins are involved in this process; however, the molecular mechanism details are unclear. We suggest that by cleaving a presynaptic protein syntaxin, which is essential in targeting synaptic vesicles(More)
Changes in synaptic density in various brain regions were assessed among different age groups of rats maintained in ordinary small cages, as determined by synaptophysin assay. The synaptophysin content in hippocampus decreases as early as in the adult stage. The most remarkable decrement occurs in occipital cortex. In other regions, synaptophysin contents(More)
A new peptide having gonadotropin-releasing activity distinct from the known luteinizing hormone-releasing hormones ( LHRHs ) has been identified in a chicken hypothalamic extract. The existence of [Gln8]LHRH in avian hypothalamus has been reported previously. The new molecular species of gonadotropin-releasing activity, named chicken gonadotropin-releasing(More)
To examine the efficacy of Lactobacillus gasseri OLL2716 (LG21) as a probiotic for Helicobacter pylori in humans, 31 subjects infected with the bacterium ingested yogurt containing LG21 daily for an 8 week period. The [(13)C]urea breath test and assays of serum pepsinogens revealed a significant improvement following LG21 treatment. LG21 was thus determined(More)
The Research Group on Progressive Renal Diseases conducted a national survey, in Japan, of cases of primary glomerulonephritis (GN) in 1985 and 1993. The results of the survey, reported here, revealed a high prevalence and relatively poor prognosis for immunoglobulin A nephropathy (IgAN). Using immunofluorescent microscopy, 47.2% of 1,063 patients were(More)
Soluble N-ethylmaleimide-sensitive factor attached protein (SNAP) receptor (SNARE) mechanisms are thought to be involved in two important processes in axonal growth cones: (1) membrane expansion for axonal growth and (2) vesicular membrane fusion for mature synaptic transmission. We investigated the localization and interactions among the proteins involved(More)
The neuronal growth-associated protein GAP-43 is expressed maximally during development and regeneration, and is enriched at the cytosolic surface of the growth cone membrane. GAP-43 can activate the GTP-binding protein G(o) which is also a major component of the growth cone membrane. These findings have led to the hypothesis that GAP-43 might modulate(More)
The step-down method can be an alternative method of ovulation induction in women with PCOS. This protocol can induce ovulation with a smaller dose of FSH and with lower incidence of excessive ovarian enlargement in comparison with the traditional fixed-dose administration method.
We report 10 cases of glomerulonephritis following methicillin-resistant Staphylococcus aureus (MRSA) infection. The clinical features of this syndrome were an abrupt or insidious onset of rapidly progressive glomerulonephritis (RPGN) with nephrotic syndrome and occasionally purpura, following MRSA infection. The renal histologic findings showed a variety(More)
