Four isolates of Entamoeba dispar identified by their hexokinase and phosphoglucomutase isoenzyme profile and by their failure to react with Entamoeba histolytica-specific monoclonal antibody (4G6) could be grown in either Diamond's BI-S-33 medium, newly developed BCSI-S (Biosate cysteine starch iron-serum) medium, or casein-free YI-S medium in the presence(More)
The nude (athymic) mouse was used as a novel test system for the evaluation of genotoxicity of genetic recombinant human erythropoietin (rhEPO). A fibroblast cell line derived from the kidneys of baby hamsters, BHK-21, or a subclone of BHK-21 transfected with an expression vector containing the human EPO gene, named BXE cells, were implanted in nude mice.(More)
A growth-promoting factor (GPF) that promotes the growth of Entamoeba dispar under axenic culture conditions was found in fractions of mitochondria (Mt), hydrogenosomes (Hg) and chloroplasts (Cp) obtained from cells of six different protozoan, mammalian and plant species. We were able to extract the GPF from the Cp-rich leaf cells of a plant (spiderwort:(More)
A novel muscarinic receptor agonist, SNI-2011 ((+/-)-cis-2-methylspiro[1,3-oxathiolane-5,3'-quinuclidine] monohydrochloride hemihydrate, cevimeline, CAS 153504-70-2), is a candidate therapeutic drug for xerostomia in Sjögren's syndrome. The general pharmacological properties of this drug on general behavior and the central nervous system were investigated(More)
We prepared thermal heterocopolymers of amino acids, aspartic acid and proline, and solubilized them in distilled water at boiling temperature. The resulting suspension was then cooled down while controlling the cooling rate. The maximum growth of phase-separated microspheres was found to occur at a finite, nonzero cooling rate. Temperature-gradient(More)
BACKGROUND Monocrotaline is a hepatotoxic agent which exerts predominant toxicity to central veins and centrilobular sinusoids. In this study, we investigated the effects of deleted variant of hepatocyte growth factor (dHGF) on monocrotaline-induced hepatic injury in rats. METHODS 100 mg/kg monocrotaline was gavaged to male rats twice with a 4-days'(More)
In this paper, we report the progress in developing a silica-aerogel-based cosmic dust capture panel for use in the Tanpopo experiment on the International Space Station (ISS). Previous studies revealed that ultralow-density silica aerogel tiles, comprising two layers with densities of 0.01 and 0.03 g/cm3 developed using our production technique, were(More)
We tested the stability and reaction of several amino acids using hydrothermal system simulators: an autoclave and two kinds of flow reactors at 200–250 °C. This study generally showed that there is a variation in the individual amino acids survivability in the simulators. This is mainly attributed to the following factors; heat time, cold quenching(More)
