Wnt3a encodes a signal that is expressed in the primitive streak of the gastrulating mouse embryo and is required for paraxial mesoderm development. In its absence cells adopt ectopic neural fates. Embryos lacking the T-box-containing transcription factors, Brachyury or Tbx6, also lack paraxial mesoderm. Here we show that Brachyury is specifically(More)
Wnt-3a mutant embryos show defects caudal to the forelimb level; somites are absent, the notochord is disrupted, and the central nervous system has a pronounced dysmorphology. Previous studies revealed that the primary defects of the mutant embryos are likely to be in the process of paraxial mesoderm formation. In this study, we analyzed the phenotype of(More)
Surface structure of myofibrils of rabbit skeletal muscle and their transverse elasticity were studied by atomic force microscopy. Images of myofibrils had a periodic structure characteristic of sarcomeres of skeletal muscle fibers. The transverse elasticity distribution in the sarcomere was determined based on force-distance curves measured at various loci(More)
Caspase-3 is one of the cystein proteases that play essential roles in programmed cell death. As such, brain development is profoundly affected by caspase-3-deficiency, resulting in hyperplasia and abnormal cell organization (Kuida et al., Nature 1996;384:368-372). In the present study, we used caspase-3 (-/-) mice to show that caspase-3 deficiency results(More)
The matrix (M) genes of Yamagata-1 strain subacute sclerosing panencephalitis virus passaged in African green monkey kidney cells and human neuroblastoma cells displayed strikingly nonrandom sequence divergence. The genes of both substrains shared a large number of uridine (U) to cytidine (C) transitions, but the latter contained numerous additional U to C(More)
Aureobasidin A (AbA) is a novel cyclic depsipeptide antifungal antibiotic. The antifungal activity of AbA was studied in vitro and in vivo in comparison with clinically effective antifungal agents, amphotericin B and fluconazole. AbA was highly active in vitro against many pathogenic fungi, including Candida albicans, Cryptococcus neoformans, Blastomyces(More)
Blood collection is a common laboratory procedure in animal experiments. The purpose of this study is to establish baseline data for two essential hematologic parameters, total blood volume (TBV) and specific gravity of blood (SGB), of nonhuman primates. The SGB was determined by dropping samples of whole blood into cupric sulfate solution. The values for(More)
Atomic force microscopic images of single skeletal myofibrils showed periodical broad filamentous bands interspaced with narrow rigid bands corresponding to the sarcomere structures of skeletal muscle (Yoshikawa, Y., Yasuike, T., Yagi, A., and Yamada, T. 1999. Biochem. Biophys. Res. Comm., 256: 13-19). In order to identify the narrow rigid bands,(More)
The prognostic value of pressure-flow study (P-FS) in the surgical treatment of bladder outlet obstruction (BOO) was retrospectively studied in patients with benign prostatic hyperplasia. In 74 patients who underwent surgical treatment for BOO, P-FS and free uroflowmetry were performed pre- and postoperatively. On P-FS, obstruction and detrusor(More)
The full-length cDNA corresponding to the mRNA for the hemagglutinin (H) protein of the Yamagata-1 strain of the subacute sclerosing panencephalitis (SSPE) virus was cloned and the nucleotide sequence was determined. The mRNA corresponding to the H protein was composed of 1952 nucleotides and contained a single large open reading frame, which encoded 620(More)
